Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a device for preventing circular objects, particularly circular objects loaded on lorries, freight cars, etc., from rolling (rotating) in one or both directions. Regarding. To explain in rough detail, Maruki,
When transporting rotatably movable cargo such as valve rolls and vehicles that are in curved contact with the loading surface, there are two types of cooperative fixing means: fixing means that ties the cargo to the loading platform, and! 1F means for preventing movement of cargo on the loading surface is required, and the present invention relates to the latter movement preventing means.

BACKGROUND OF THE INVENTION West German Patent Nos. 414,974 and 415,858 disclose a fixing device for preventing rotational movement of barrels during transportation by freight cars or lorries. The fixing device consists of four blocks arranged at the four corners so as to form a rectangular shape as a whole. Among the blocks, the long side parts with large distances are connected by square iron bars so that the blocks are parallel to the iron bars, and the short sides with small distances are connected with chains and springs are installed. It is urging them to attract each other.

Problem to be Solved by the Invention This known device has the disadvantage that the cooperation between the iron bar, the block and the chain must all work properly. Normally, inserting this device under a large object to be fixed is a cumbersome task, as the chain on the short side must be loosened beforehand, and the device must be repositioned between the two inner blocks after insertion. Even without a chain or other connecting device, both outer blocks will work for a while, but in that case the fixed state will eventually loosen due to vibrations, movement of cargo, etc. Further, when connecting blocks with a chain, it is necessary to grasp both blocks when positioning the fixing device.

Means for Solving the Problem The present invention has been made in view of the above-mentioned problems, and it is possible to insert the object to be fixed from one side, grip it during positioning, and maintain the space between the locking blocks in a good condition. The purpose is to provide a fixation device that can be held.

This purpose consists of mutually self-sufficiently guided holding members and
spring means acting between the retaining members and biasing the retaining members toward each other, the first lock having a free end of one of the retaining members generally wedge-shaped; the other of the holding members is configured to fit into the body to restrict rotational movement of the circular object in one direction, and the free end of the other holding member is opposite to the one direction of the circular object. Either a wedge-shaped second locking body configured to restrict rotational movement in the direction or a roller means that allows rotational movement of the circular object in the opposite direction is fitted. This is achieved by an anti-rolling device designed as follows.

EXAMPLES The present invention will now be described with reference to the accompanying drawings showing examples.

FIG. 1 shows a state in which a circular object (2), such as a car wheel, is placed on a placement plane (1). This circular object is fixed against rotational movement using the device (3) according to the invention. This device (3) consists of two wedge-shaped locking blocks (4,
5), and both locking blocks (4, 5) are the first and second locking blocks (4, 5).
They are interconnected by retaining members (6, 1). At least the first holding member (6) has a cylindrical shape, and the second holding member (7) is inserted into the first holding member (6) so as to be telescopically movable. The elastic force of the spring acts between the holding members (6, 7), urging the locking blocks (4, 5) in the direction opposite to each other. Preferably, the second holding member (7) is also cylindrical, and the tension coil spring (8) is guided inside both cylindrical holding members (6, 7). Both ends of the tension coil spring (8) are connected to the cylindrical first and second holding members by connecting pins (9, 10) penetrating through holes provided in both end side wall surfaces of each holding member. . 1st・
Each open end of the second holding member has a plastic plug (11, 12).
) is occluded.

From the first and second holding members (6, 7), the holding rods (13
, 14) preferably project at right angles (FIG. 2) and are fixedly connected to the respective retaining member. Holding rod (13, 14)
are respectively inserted into the locking blocks (4, 5) through openings extending laterally through the locking blocks (4, 5).

At the free end of the holding rod (13, 14) is a bending pin (5).
is attached to prevent the holding rod (13°14) from being manipulated.

The holding members (6, 7) may have a polygonal cross-section, preferably a rectangular cross-section, to prevent rotation of the holding members relative to each other. In the illustrated example, the first and second holding members (6, 7) have a square cross section. Also, Yuji Samurai (1)
3, 14) is provided on the locking block (4, 5) in order to fit such a holding rod. In the illustrated example, the retaining rods (13, 14) also have a square cross-section.

In order to increase the friction between the mounting plane (1) and the locking blocks (4, 5), the locking block ('4.5) is coated with a coating Ft (is, 17) made of a thin rubber material r11. It is also useful to provide

The spring (8) has enough elasticity to allow the first and second holding members to be easily stretched by hand, and the first holding member (6) of both holding members is in contact with the holding rod (14). Shortest state (
From FIG. 2), it is extended by the distance widened in order to insert the locking blocks (4, 5) on both sides of the circular object (2) to be fixed. Further, the spring (8) biases the locking blocks (4, 5) in the mutually opposing direction when the locking blocks (4, 5) are under no load, that is, when the friction between the locking blocks and the mounting plane (1) is relatively small. It has sufficient elasticity. When the object (cargo) to be fixed moves or moves up and down when the transportation vehicle is braking, the locking block that is in a no-load state will stop locking when the degree of no-load becomes large enough. If the blocks are spaced too far apart or spread out too much and the cargo is not secured properly, they will move close to each other.

In this embodiment, the locking blocks (4, 5) have a welded box structure made of steel or aluminum, and each locking block has an ear (18) welded to it for loading and unloading of cargo. It is designed to be used when removing the device (3) such as when That is, press a pry tool such as a crowbar against the ear (18) to lift the locking block from the mounting plane, stretch the first and second holding members (6, 7), and remove them from the cargo that has been fixed up until now. It looks like this.

In the above-described embodiment, the expansion movement width of the locking block is limited to a certain length. Therefore, in the second embodiment shown in FIGS. 3 to 5, the expansion movement width can be variably adjusted. Regarding the reference numerals, the same reference numerals indicate corresponding members, and similar members are indicated with the same reference numerals followed by a change code.

The locking block (4') shown in FIGS. 3 and 4.

5') consists of an extruded aluminum profile. The interior of this profile will not be described in detail. The ears (18=) extend over the entire width of the locking block (4-, 5=). The expansion and contraction action in this embodiment is the same as that in the first embodiment described above,
Cylindrical holding member (6>, holding rod (13), spring (8),
There is no change in the configuration of the connecting bins (9, 10). Similarly to the second holding member, the cylindrical body (7') is provided in the first holding member (6) so as to be movable, and the cylinder body (7') is provided in the holes provided in both side wall surfaces at a position closer to the end than the connecting bottle (10). The snap spring (19) is visible. Both ends of the snap spring (19) are bottle-shaped engaging ends (20, 21) that are fitted into the holes. In this embodiment, the connecting bottle (10) is provided at a position where the distance -1 from the end of the holding member is greater than in the first embodiment.

One end of the cylindrical body (7') is inserted into a cylindrical third holding member (22) having the same cross-sectional dimensions as the first holding member (6) and a short length. Holes (23, 24) are provided on both side walls near the end of the third holding member (22), and snap springs (1
The cylindrical body 7') and the third holding member (22) are interconnected by fitting the engaging ends (20, 21) of 9) with their elasticity. From the third holding part shrine (22), the second holding member (
7) As in the first embodiment, a retaining rod (14=) projects laterally and is fixed to a locking block (5'), and a bending pin (15) is also provided.

The device according to the second embodiment has the same function as the device according to the first embodiment, and the expansion movement width is also limited.

By pressing down the engaging ends (20, 21) at both ends of the snap spring (19), the cylinder body (7') and the third holding member (22) can be separated, as shown in Fig. 4. It is also possible to connect both holding members with a joint member (25) not shown.

The joint member (25) is 2 which is telescopically engaged with the phase n.
The cylinder (26) has the same cross-sectional dimensions as the cylindrical first holding member (6), and the cylinder (27) has the same cross-sectional dimensions as the cylinder (7-). It has a cross-sectional dimension of.

The joint member (25) is arranged between the cylindrical body (7-) and the third holding member (22), as shown by the arrow in FIG.

FIG. 5 shows details of connecting the cylindrical body 7' and the holding member (22) using the joint U (25>).

Opposing holes (28, 29) are provided in the cylindrical body (26), and the engaging ends (20, 21) of the snap spring (19) connect the cylindrical body (1-) to the cylindrical body (26)). When it enters the hole (28
, 29), and both cylindrical bodies (7', 26) are locked to each other. A cylindrical body (26) extending from inside the cylindrical body (26)
A snap spring (30) is disposed within the end of the snap spring (30), and the locking ends (31, 32) at both ends of the snap spring (30)
) passes through holes provided on both side wall surfaces of the cylinder (27). When the cylindrical body (21) is inserted into the third holding member (22), the engaging ends (31, 32) fit into the hole (22) of the third holding member (22).
23, 24), it is made to fit 18 times due to elasticity. If the cylindrical body (7') and the third holding member (22) are connected as described above using the joint member (25), the locking block (4
", 5') can be expanded to any desired width.

In order to fix the joint member (25) at any position, the cylindrical body (
A plurality of pairs of holes (33, 34) are provided on the opposite side wall surfaces of the cylinder (26), and the other end of the cylinder (27), that is, the end opposite to the end where the snap spring (30) is provided. A snap spring (35) is also provided in the same manner. The locking ends (36, 37) forming both ends of the snap spring (35) are connected to the hole (33).
34) can be elastically fitted.

When rolling (rotating) a circular object, there are cases where it is necessary to roll it only in one direction. An example of this is when a plurality of pulp rolls or cylinders are loaded onto a freight car or a port car from the rear end. In this case, the roll is rolled until it hits the front wall of the vehicle. The third example is constructed with this purpose in mind.

As the third embodiment of the present invention is shown in FIGS.
Basic members constituting the second embodiment, namely, first and second telescopic holding members (6, 7), holding rods (13, 14) extending from the holding members, and a wedge-shaped lock attached to the holding rod. block (4).

A roller means (40) including two rollers (/11.42) is attached to the holding rod (14) of the second holding member (7). Both days - La (41, 42) is the holding rod (14
) can be freely rotated individually around each axis parallel to the axis. In the illustrated embodiment, the f-yaw 5 means are attached to the retaining rod <1
4) A boulder (49) is attached so as not to rotate, and a shaft is attached between a pair of brackets (45, 46: 47, 48) each extending from this holder (49) in opposite directions. The rollers (43, 44) are in the center (
41, 42) are configured to rotate. The holder (49) consists of a housing having an inner cross-sectional dimension corresponding to the outer surface dimension of the holding rod (14), and is slidable along the holding rod.

As in the other embodiments, a bend stop pin (15) prevents the holder (49) from coming off the retaining rod.

Preferably, with the roller means attached, the roller (41
, 42), the planes in which the shafts (43, 44) extend together form an angle of about 45° with the retaining member (7).

The device according to the third embodiment is placed around a circular object to be fixed in a similar manner to the devices according to the other embodiments. As shown in FIG. 7, when this device is used on a circular object (50) with a relatively large diameter such as a pulp roll, the circular object will block the wedge-shaped lock even if it tries to roll to the right. (4) It is closed and cannot roll, but it can roll to the left. This is because the circular object (50) and the roller (42) are in contact with each other, and the roller (41) and the mounting plane (1) are in contact with each other.

When the circular object (50) rolls to the left, the telescopic holding members (6, 7) with built-in springs expand slightly.
The locking block (4) is placed in an unloaded state, and then the locking block (4) is pulled together. When it collides with the wall of the freight car or a circular object that has already been loaded and is unable to proceed roughly to the left, the circular object (50) bounces and tries to return to the right, but the locking block ( 4) is closed.

FIGS. 8 and 9 show a device according to a third embodiment of the present invention in a relatively small diameter circular object or a circular object (51° 52, 53
) shows how to use it. In the figure, the roller means (
40) is inserted inside one of the circular objects 52), and the cone-shaped locking block (4) is inserted into another adjacent circular object (53).
is engaged in. In Fig. 8, the circular objects (52, 53) both move to the left, and the circular object (52) moves 4? It does not show the state where it just hit another circular object (51) which is loaded on the wagon and is in contact with the wall of the freight car. At the next moment, the circular object (53) collides with the circular object (52), and the first and second holding part shrines (6
, 7> by the spring acting between them, the locking block (
4) is able to maintain its proximity to the circular object (53) and prevent the subsequent circular object (53) from rebounding to the right.

As roughly shown in FIG. 8, one or both of the rollers (44, 42) rotate within the circular object (52) while the circular object (52, 53) rolls to the left. 1st・
The second holding members (6, 7) move upward, and roughly the locking block (4) rises upward from the mounting plane (1), causing the locking block (4) and the mounting plane (1) to move upward. fIJ friction between the two is reduced.

As can be seen from the above description, the first and second embodiments of the present invention can be easily changed to the third embodiment by simply replacing one of the locking blocks with a roller means.

In addition to the above-mentioned applications, the device according to the present invention can also be used as a locking block means for an aircraft, or a locking block means for a passenger car or truck mounted on a ferry.

Effects of the Invention The anti-rolling device according to the present invention uses a spring to urge the two wedge-shaped locking blocks in mutually opposing directions, so it is easy to arrange the blocks close to both sides of a circular object to be fixed. can. Further, when restricting the rolling direction of a circular object to one direction, this can be done simply by interlocking one of the locking blocks with the roller means. Therefore, there is no need to adjust the spacing of the locking blocks every time the device is used in accordance with the width of the circular object.
