Description

[Detailed Description of the Device] (a) Field of Industrial Use This device is designed so that the tip of a set screw that is screwed into a pad interposed between a clasp and a basic rail is brought into contact with the upper surface of the root of the basic rail. ,
By pushing the basic rail downward, the holding piece at the tip of the claw bolt is prevented from swinging due to vibration or impact due to train passing or track maintenance work, and the pointed rail can always be in close contact with the basic rail at a fixed position. The present invention relates to a locking device holding device for a roll holder.

(B) Conventional technology While the electric rolling machine is being installed on the track, it cannot function as a rolling machine yet.Therefore, the rolling point is temporarily set at a fixed position. In order to hold it, for example, as shown in FIGS. 4 to 9, a substantially L-shape is formed at the rear (right side in FIG. 4) of the claw bolt 1 in which the spiral s is engraved in the front (left side in FIG. 4). The hug piece h of is integrally formed,
The tip rail 2 is pressed against the basic rail 3 by the inner wall surface of the holding piece h.
While closely contacting each other, the bulging portion e having the through hole d is integrally projected beyond the middle of the sleeve 4 partially screwed into the spiral s, and the bulging portion e is held in the middle. Of the pair of U-shaped arm pieces a ₁ and a ₂ of the clamp 5, which are formed on the front and upper sides, through holes b ₁ and c
And a notch v for weight reduction on the lower rear side of the clasp 5, and side plates W ₁ and W ₂ on the outer front side of the arm pieces a ₁ and a ₂ of the clasp 5, respectively. Through holes g and i are formed at the upper and lower sides of the rocker 6 to be provided alongside, and the clasp 5 and the rocker 6 are rotatably supported by the pin 7 which penetrates the through holes d, b and g. The retaining pin 8 is inserted into one end of the pin 7 to prevent the clamp 5 and the rocker 6 from coming off the pin 7, and is clamped via a washer 9 and a spring washer 10 which are fitted to the spiral s in front of the sleeve 4. Tighten the nut 11 to the spiral s, and
The pawl bolt 1 is inserted below the pad 12 that is interposed between the base rail 3 and the base rail 3, and the pawl bolt 1 is sandwiched between the forks f and f that are branched and formed at the lower rear of the pad 12. There is. Further, the locking piece 13 inserted through the through holes c and i in the lower part of the clamp 5 and the rocker 6 is engaged with and disengaged from a locking device (not shown) so that the pawl bolt 1 and
The clamp 5 and the rocker 6 are integrally connected, and the basic rail 3 and the tip rail 2 can be brought into close contact with each other as shown in FIG.

(C) Problems to be solved by the invention In the rolling device locking metal fitting mechanism of the above-mentioned type,
When the train passes through the rolling point or the track maintenance work is performed, although the middle of the claw bolt 1 is held by the forks f of the contact plate 12, the contact plate 12 itself is
Since it is in a state of play against any of the basic rails 3,
In FIG. 4, the gripping piece h oscillates from the front side to the back side with respect to the paper surface, so that the tip rail 2 cannot be brought into close contact with and held by the basic rail 3 at a certain position, and the reliable rolling function is achieved. There is a problem that you cannot do it.

The present invention was proposed by paying attention to the above-mentioned drawbacks, and the purpose thereof is to make the holding piece swinging at the tip of the claw bolt by contacting the end of the set screw screwed with the pad to the basic rail. An object of the present invention is to provide a rolling device locking device holding device capable of preventing movement.

(D) Means for Solving the Problems In order to achieve the above-mentioned object, the rolling device locking metal fitting holding device according to the present invention comprises a rocker, a sleeve, a clasp, and a pointed rail through a lower part of the basic rail. A claw bolt having a holding piece at its tip end that comes into contact with, a locking piece integrally connecting these members, a set screw, and a metal plate interposed between the clamp and the basic rail. It is a rolling device locking device holding device, wherein the backing plate is substantially L-shaped, and the arm piece formed above the rear part is made to face the root upper surface of the basic rail, and the female screw engraved on this arm piece A set screw is screwed onto the base, and the tip of the set screw is brought into contact with the upper surface of the root portion to press the basic rail downward to prevent the holding piece at the tip of the claw bolt from swinging.

The invention will be described with reference to FIGS. The structure of each of the claw bolt 1, the sleeve U, and the rocker L according to the present invention is the same as that of each member of the above-mentioned conventional type, and therefore the description thereof is omitted, and the clasp K is the end portion on the basic rail R side. Although it is slightly different from the conventional one in that it is formed in a substantially semicircular shape, the other points are the same and the description thereof is omitted. A substantially L-shaped pad J having a circular middle section m penetrated in the middle of the claw bolt 1.
A female screw 22 is engraved in the middle of the upper arm piece 21, and the tip (here, the lower end) of a set screw 23 screwed onto the female screw 22 is brought into contact with the upper surface of the root portion 24 of the basic rail R, while the pad J As shown in FIG. 3, the lower portion of the claw bolt 1 on the holding piece h side is formed into a pair of fork pieces 25, 25 facing each other as in the case of the conventional pad 12, and the fork pieces 25, 25 are formed.
Hold the claw bolt 1 with. In the figure, 26 is a washer, 27 is a spring washer, 28 is a locking piece, N is a tightening nut, P is a pin,
q is a retaining pin, and T is a pointed rail.

(E) Action / Effect Since this invention has the above-mentioned structure, the locking piece 28 is engaged with a locking device (not shown), while the tip of the set screw 23 is a basic rail R as shown in FIG. When it comes into contact with the upper surface of the root portion 24 of the clamp 24,
Is held in a fixed position by the
And the lower part of the basic rail R of the claw bolt 1 is clamped and fixed by the fork pieces 25 of the pad J, so that the clamp K, the rocker L, the sleeve U,
Since the pad J and the claw bolt 1 are integrally connected to the basic rail R, the holding piece h of the bolt 1 is also held at a fixed position and does not swing even by vibration, impact, etc. The rail R and the tip rail T can always maintain a close contact state,
It can perform a reliable rolling action, and by screwing a set screw to a hitherto used in the past, bringing its tip into contact with the basic rail and pressing it downward, This has the advantages that it can prevent swinging, is extremely simple and reliable as means for preventing swinging of the claw bolt, and can be easily handled by anyone.
