Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a tilting transport device for long objects, and in particular, a device for transporting long objects from an upper floor in a multi-story building to a lower floor by using an opening. The present invention relates to a tilting transport device suitable for transporting long objects.

[Conventional technology]

Conventionally, when transporting long objects such as piping and scaffolding materials to and from work sites in multi-story buildings such as power plants,
Upper floor openings near the work area are often used. In this case, a long object is suspended almost vertically using an overhead crane installed on the upper floor of the building, and then lowered from the opening to the lower floor using an overhead crane. While pulling the object with ropes, etc., a plurality of chain blocks etc. are temporarily installed on the ceiling of the lower floor to adjust the long object to a substantially horizontal state and transport it to the work site.

However, with the above method, the temporary setup of the chain block is time consuming and work efficiency is low.Furthermore, since the long object is adjusted to a substantially horizontal state while being suspended substantially vertically, it is said that the chain block is likely to come off from the hanging wire rope. There were deficiencies that created safety problems.

[The problem that the idea aims to solve]

The present invention eliminates the drawbacks of the prior art and allows long objects to be easily and safely tilted from a vertical position to a horizontal position without the need for setup such as a chain block, and after tilting, travels on the floor to the work area. An object of the present invention is to provide a tilting conveyance device for long objects that can convey long objects up to 100 degrees.

[Means to solve the problem]

The present invention includes a pair of horizontal guide rails provided on the floor, a pair of vertical guide rails standing upright on one end side of the horizontal guide rails, a horizontal moving means movable guided by the horizontal guide rails, and a horizontal moving means that is movable while guided by the horizontal guide rails. a frame-shaped truck that is movable up and down guided by vertical guide rails and that moves horizontally by engaging the horizontal moving means at the other end; lifting means for the truck that engages with one end of the truck; a vertical motion adjustment mechanism provided at the other end of the vehicle for raising and lowering the vehicle and the horizontal moving means; and wheels that touch the ground when the vehicle is lowered by operation of the vertical motion adjustment mechanism; The vehicle is characterized in that it can run on the floor even if it separates from the horizontal guide rail.

[Effect]

In this invention, a long object is loaded onto a cart whose both ends are engaged with a vertical guide rail and a horizontal guide rail, and one end of the cart is moved up and down by a lifting means that moves up and down along the vertical guide rail. Then, since the center of gravity of the long object is on the vertical beam side from the engagement position of the horizontal movement means at the other end of the cart, the other end of the cart naturally moves along the horizontal guide rail to the side opposite to the vertical guide rail. It can be moved and the cart can be tilted. Further, when the truck is tilted to a substantially horizontal state, the entire truck is lowered by a vertical adjustment device attached to the horizontal moving means, and the wheels attached to the truck are grounded on the floor, so that the truck can run on the floor.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is an overall configuration diagram of one embodiment, and Figure 2 is a diagram of the first embodiment.
Fig. 3 is a view from B to B in Fig. 1, Fig. 4 is a view from C to C in Fig. 3, Fig. 5,
, are side views showing changes in the tilting state of the truck in the example.

As shown in FIG. 1, this embodiment includes a pair of parallel horizontal guide rails 12 temporarily installed on the floor 11 of the lower floor 31, and an opening 13 of the upper floor 29 that abuts one end of the horizontal guide rails 12. A pair of parallel vertical guide rails 14 erected so as to penetrate through the
There is. A hoist 15 is suspended from a beam 16 above the vertical guide rail 14. The center portion of the hoist 15 is suspended from the hook 15a, and both ends are connected to the vertical guide rail 14 by rotating rollers 17.
There is a lifting beam 18 as a lifting means fitted into the guide groove 14a.

The lifting beam 18 is connected to the hook 15a of the hoist 15.
By winding up or lowering the vertical guide rail 14, the rotating roller 17 fitted along the guide groove 14a of the vertical guide rail 14 rotates and moves up and down. The pair of horizontal guide rails 12 also have guide grooves 12a, and two rotating rollers 19 are rotatably fitted into each guide groove 12a. As shown in FIG. 3, two rotating rollers 19 are connected by a frame 19a, and these opposing frames 19a are connected by a horizontally moving beam 20 serving as a horizontally moving means.
The horizontal beam 20 has two pins 21 and this pin 2.
A pin support 21a for pivotally supporting 1 is attached.

The truck 22 has a hook 23 at one end 22a, and the hook 23 is rotatably hooked onto the lifting beam 18. Trolley 22
As shown in FIG. 4, the other end portion 22b includes a metal fitting 24 that loosely connects the pin 21 and this metal fitting 2.
Guide groove 25 for adjusting the position of 4 in the vertical direction
There is a guide block 25a. A screw shaft 25b is engaged with this guide block 25a, and this screw shaft 25b is threaded by rotating a handle 25c attached to the upper part of the guide groove 25, thereby moving the guide block 25a up and down.
The trolley 22 has a flat frame structure, and has four running wheels 26 attached to its lower surface. The other end 22b of the cart 22 has a pedestal 28 on which a long object 27 is loaded, and the guide groove 25 is attached to the bottom surface of the pedestal 28 on the side opposite to the loading side.

A method of using this embodiment with the above configuration will be described next.

As shown in FIG. 5, the pedestal 28 of the trolley 22 of the long object tilting device 10 is waiting for a long object 27 suspended substantially vertically by an overhead crane or the like on the upper floor 29.
Load on top. After loading the long object 27, the hook 15a of the hoist 15 attached to the top of the vertical guide rail 14 is lowered as shown in FIG. One end 22a of the truck 22 is gradually guided by the horizontal movement beam 20 of the rail 12.
is lowered, and the other end portion 22b moves and tilts in the direction of arrow F.

For tilting, the center of gravity G position of the long object 27 is moved from the pin 21 position of the horizontally moving beam 20 to the vertical guide rail 1.
4 side, the rotating roller 19, which is necessarily engaged with the horizontally moving beam 20, naturally rolls in the direction of the arrow F at the same time as the lifting beam 18 descends. Next, as shown in FIG. 5, when the trolley 22 becomes approximately horizontal on the lower floor 31, lowering of the hoist 15 is temporarily stopped. At this time, the traveling wheels 26 on the lower surface of the truck 22 are not in contact with the floor 11 of the lower floor 31. The reason why the hook 23 does not touch the ground is to prevent the hook 23 from coming off the lifting beam 18 during tilting due to the thrusting force caused by the grounding. In this state, the guide block 25a in the guide groove 25 on the bottom surface of the pedestal 28 of the cart 22 on the opposite side of the load shown in FIG. 4 is pulled up by turning the screw shaft 25b using the handle 25c. , the other end 22b side of the truck 22 descends relatively, and the wheels 26b on the other end 26b side of the running wheels 26 touch the floor 11. Then, the hoist 15 is further lowered. Then, the wheels 26a on the one end 22a side of the truck 22 also come into contact with the floor 11. At the same time, the hook 23 is also removed from the lifting beam 18. In this state, if the trolley 22 is pushed or pulled in the direction of the arrow P using an input or other method, the trolley 22 will be moved along the horizontal guide rail 12 to the floor 11 of the lower floor 31. Can be moved horizontally on top. In the above explanation, the case of moving down from the upper floor 29 to the lower floor 31 has been explained, but when moving up from the lower floor 31 to the upper floor 29, it can also be done by performing the operation in the reverse order.

As explained above, according to this embodiment, the long object 2
When unloading and transporting 7 from the upper floor 29 to the floor 11 of the lower floor 31 using the opening 13, the long object 27 suspended approximately vertically is loaded onto the pedestal 28 of the trolley 22. For example, it can be tilted approximately horizontally easily and safely. Furthermore, the movement in the direction of arrow P in the almost horizontal state is caused by the guide groove 1 of the horizontal guide rail 12.
Even if the rotating roller 19 is detached from the end 12b of the horizontal guide rail 12, as well as within the section where the rotating roller 19 is fitted into the horizontal guide rail 12, the rotating roller 19 will move along with the horizontal moving beam 20 to the cart 22.
Since it is suspended from the horizontal guide rail 12, it can be moved even outside the section where there is no horizontal guide rail 12. Therefore, the chain block can be transported horizontally without having to temporarily set up the chain block on the ceiling 32 of the lower floor 31.

In this embodiment, as shown in FIG. 1, the opening 13 is located near the building wall 33, and the vertical guide rail 14 is supported along the building wall 33.
As shown in FIG. 6, by providing a support 34 even in an opening 13 where there is no building wall 33, it can be temporarily installed anywhere.

Further, in this embodiment, the guide groove 12a of the horizontal guide rail 12 and the guide groove 1 of the vertical guide rail 14
Although rotating rollers 17 and 19 are fitted into each of the rollers 4a, these may be slide blocks instead of the rotating rollers 17 and 19.

Further, in the present invention, the guide block 25a is moved up and down by the screw shaft 25b, but it may be moved by other methods, such as a rack and pinion type or a hydraulic cylinder type.

[Effect of idea]

Since the present invention is configured as described above, it has the following effects.

A long object suspended approximately vertically is placed on the pedestal of a cart whose both ends are supported by a vertical guide rail and a horizontal guide rail, and one end of the cart is lifted by a lifting beam that moves up and down along the vertical guide rail. By raising and lowering the trolley, the cart can be tilted to easily and safely hold a long object in a horizontal or vertical state.

Furthermore, a long object placed in a horizontal state can be placed on the trolley and transported horizontally to the desired work location.
