DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a railway rail laid on a sleeper such as a concrete sleeper which is used for fastening or releasing the rail to or from the sleeper using an e-type spring clip. The present invention relates to an e-type spring clip attachment / detachment tool.

[0002]

2. Description of the Related Art In order to fasten or release a railway rail laid on a sleeper to the sleeper using an e-type spring clip, the e-hole is inserted into an insertion hole provided in a receiving stand fixed on the sleeper.
Although the insertion end of the type spring clip is moved in and out,
As an instrument for performing the in / out operation, that is, the operation of attaching / detaching the clip to / from the receiving table, for example, Utility Model Registration No. 2514472
There is a structure described in the official gazette.

This conventional example has a structure in which a base of a claw provided with a locking claw on the distal end side is rotatably connected to an intermediate portion on the distal end side at an angle of an operating handle having a distal end as a receiving portion. It is.

[0004]

In the above prior art, the receiving portion is brought into contact with the end surface of the receiving base, and the locking claw is hooked on the arc-shaped receiving portion of the e-shaped spring clip to extend around the receiving portion. The e-clip is attached to and detached from the cradle or the sleeper by rotating the operation handle by a child action. However, since the receiving portion has an arc shape, the rotation operation of the operation handle is performed. Sometimes, the hooking position of the locking claw with respect to the receiving portion is shifted or the locking claw is disengaged from the receiving portion, so that the above operation cannot be performed smoothly.

The present invention has been devised in view of the drawbacks of the prior art in order to provide a device which can smoothly attach and detach (rotate an operation handle) an e-type spring clip to a receiving stand or a sleeper. It is.

[0006]

Means for Solving the Problems A pressure receiving portion having a receiving portion as a receiving portion is protruded from a tip piece continuously provided at an angle to the tip of the operating handle, and is in the same direction as the projecting direction of the pressure receiving piece. A claw provided with a locking claw on the distal end side is pivotably pivotally attached to an intermediate portion of the distal end piece, and a side edge of the e-type spring clip or A guide piece that slides on a side edge of the receiving stand to which the e-type spring clip is attached, which is opposite to the side edge of the clip, is provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view, FIG. 2 is a side view, and FIG.
FIG. 4 is a front view showing an e-type spring clip assembling operation, FIG. 4 is a front view showing an e-type spring clip removing operation, and FIG. 5 is a plan view showing a relationship between the e-type spring clip and a railroad rail.

In the drawing, reference numeral 1 denotes an operation handle, and a tip piece 3 constituted by a pair of parts 3a, 3a opposed to each other with a gap 2 is provided at an end (lower end) of the operation handle 1 at an angle. At the tip (lower end) of the tip piece 3, the base is attached to the piece 3
a, 3a, and a pressure receiving piece 4 having a receiving end 4a at its tip is provided in a horizontal state to protrude therefrom.
In the same direction as above, a claw piece 5 is pivotally connected to the intermediate portion of the tip piece 3 so as to be freely rotatable. The claw piece 5 is provided with a pair of front and rear locking claws 5a and 5b which are displaced to the front end side, and on the base side where the gap 2 between the pieces 3a and 3a constituting the front end piece 3 is penetrated. A bolt 6 penetrating through the pieces 3a, 3a together with the side, and a nut 7 screwed to the bolt 6 are tightened, and the bolt 6 is pivotally attached to the intermediate portion of the tip piece 3 with the bolt 6 as a pivot axis as described above. is there.

A guide piece 8 is cantilevered and protrudes from the tip of the side surface of the claw piece 5, and the guide piece 8 is displaced in the projecting direction of the guide piece 8 with respect to the claw piece 5. The first and second pair of arm pieces 8a and 8b protrude in the direction of the pressure receiving portion, and the first arm piece 8a is attached to the side edge 9a of the e-shaped spring clip 9 and the second arm piece 8b. Are slidably in contact with a side edge 10a of the receiving stand 10 on which the e-type spring clip 9 is assembled (inserted), which side is opposite to the side edge 9a of the e-type spring clip 9.

After the insertion end of the e-shaped spring clip 9 is slightly inserted into the insertion hole (not shown) of the receiving base 10 provided in the sleeper 11, the second attachment / detachment tool A according to the above-described configuration is used. The receiving portion 4a of the pressure receiving portion 4 is applied to one end face 10 'of the receiving base 10 so that the arm portion 8b contacts the side edge 10a of the receiving base 10, and the rear locking claw 5b of the claw 5 is set to e. When the operating handle 1 is rotated by a lever action around the receiving portion 4a by hooking and locking to a receiving portion 9 'formed by folding over the mold spring clip 9 (FIG. 3), The insertion end of the e-type spring clip 9 moves in the insertion hole along the insertion hole as pulled by the stopper 9 ′. As a result, the e-type spring clip 9 presses the fastening piece 12 against the rail 13. And rail 13 is sleeper 1
1

During this fastening (assembling) operation, the second arm piece 8b of the guide piece 8 always comes into sliding contact with the side edge 10a of the pedestal 10, so that the locking claws 5a, 5b contact the receiving portion 9 '. The locking position is kept constant, and the turning operation (fastening operation) of the operation handle 1 is performed without any inconvenience.

In order to remove the e-type spring clip 9 from the pedestal 10 or the sleeper 11, the position of the attachment / detachment A is set in a direction different from the direction of fastening when the e-type spring clip 9 is inserted into the pedestal 10. The receiving portion 4a of the pressure-receiving portion 4 is positioned at the opposite side, that is, such that the first arm portion 8a of the guide piece 8 is in contact with the side edge 9a of the e-shaped spring clip 9. One end face 10 ″ is opposed to the end face 10 ′, and the front locking claw 5 a of the claw piece 5 is engaged with the receiving portion 9 ′ of the e-shaped spring clip 9.
(FIG. 4), and the operation handle 1 is received by the receiving portion 4a.
(This operation is almost the same as that at the time of the above-mentioned fastening), pull out the e-type spring clip 9 from the insertion hole of the receiving base 10, and press the e-type spring clip 9 against the rail 13. During this operation, the first arm piece 8a is always in sliding contact with the side edge 9a of the e-shaped spring clip 9 during this operation, so that the locking claws 5a,
The locking position of 5b with respect to the receiving portion 9 'is kept constant, and the turning operation of the operation handle 1 is performed without any inconvenience as in the case of fastening.

In the drawing, reference numeral 14 denotes a rail pad.

[0014]

The present invention has the configuration described above,
The attachment / detachment operation of the e-type spring clip with respect to the sleeper or the pedestal can be performed smoothly. Particularly, during the attachment / detachment (rotation of the operation handle), the guide piece always slides on the pedestal or the side edge of the clip, The displacement of the fulcrum of the operation handle is unlikely to occur,
Therefore, the hooking position of the locking claw with respect to the receiving portion of the e-type spring clip is kept constant, and the above-mentioned attaching / detaching operation can be performed even more smoothly.
