Description

Technical Field

[0001] The utility model belongs to the technical field of subway signal system switch machine maintenance, in particular to a subway signal system switch machine maintenance device. Background Art

[0002] When inspecting and repairing the switch machine of the subway signal system, it is necessary to use a switch track close-fitting detection hammer to test the switch track to determine whether there is a fault in the switch machine.

[0003] Since the front test piece of the conventional switch track close fit detection hammer cannot be folded and requires a relatively large space for storage, during the test, the instantaneous pulling force when the switch track is switched acts on the arm through the switch track close fit detection hammer. The force is relatively large, causing certain discomfort to the arm, thus resulting in the problem of low practicality of the conventional switch track close fit detection hammer.

[0004] Therefore, we propose a subway signal system switch machine maintenance device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem of low practicability of conventional switch track close-fitting detection hammers, and proposes a subway signal system switch machine maintenance device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A subway signal system switch machine maintenance device includes a guide sleeve, a slide rod is slidably installed inside the guide sleeve, the front end of the slide rod is fixedly connected to a bearing seat, the front part of the bearing seat is rotatably connected to a swivel seat, the upper part of the swivel seat is threadedly installed with a bolt, a detection piece is sandwiched between the swivel seat and the bolt, and the outer movable sleeve of the slide rod has a spring, the front end of the spring is fixedly connected to the slide rod, and the rear end of the spring is fixedly connected to the guide sleeve. Hold the guide sleeve, and then hang the detection piece on the target branch rail. When the detection piece is subjected to outward pulling force, the detection piece acts on the bearing seat, and the bearing seat acts on the slide rod, so that the slide rod overcomes the elastic force of the spring and slides forward along the guide sleeve. The spring is used to buffer the force to improve the comfort of operation. After use, the detection piece and the swivel seat are folded backwards to save storage space, thereby improving practicality.

[0008] Preferably, a leather sheath is fixedly connected to the rear of the guide sleeve, so as to increase the comfort of holding the guide sleeve.

[0009] Preferably, the bearing seat comprises a bearing and a first seat body, wherein the first seat body is fixedly connected to the front end of the slide rod, and the bearing is used to conveniently guide the rotation of the swivel seat.

[0010] Preferably, the bearing seat further comprises a snap button, one end of which is fixedly connected to the bearing, and the snap button is fastened to the side of the swivel seat to increase the stability of the swivel seat in the unfolded state.

[0011] Preferably, the rotating seat comprises a second seat body and a rotating shaft, and the rotating shaft is symmetrically fixedly connected to the side end of the second seat body. When the detection sheet is flipped backward, the rotating seat is driven to flip backward by the detection sheet, thereby reducing the side area occupied by the detection sheet.

[0012] Preferably, the rotating seat further comprises a blocking bar, which is symmetrically fixedly connected to the side of the second seat body. The blocking bar is used to block the side of the detection piece to prevent the detection piece from rotating.

[0013] Preferably, the bolt includes a knob, a pressure block and a threaded rod, and the pressure block is fixedly connected between the threaded rod and the knob. The operation knob drives the pressure block to rotate, and the pressure block drives the threaded rod to rotate, and the threaded rod is tightened in the second seat body, so that the pressure block presses or loosens the detection piece, thereby facilitating the replacement of the detection piece.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Hold the guide sleeve, and then hang the detection piece on the target branch track rail. When the detection piece is subjected to outward pulling force, it acts on the bearing seat through the detection piece, and acts on the slide bar through the bearing seat, so that the slide bar overcomes the elastic force of the spring and slides forward along the guide sleeve. The spring is used to buffer the force to improve the operating comfort. After use, fold the detection piece and the swivel seat backwards to save storage space, thereby improving practicality.

[0016] 2. When flipping the detection piece backward, the detection piece drives the rotating seat to flip backward, reducing the side area occupied by the detection piece, and the operating knob drives the pressing block to rotate, and the pressing block drives the threaded rod to rotate, and the threaded rod is tightened in the second seat body, so that the pressing block presses or loosens the detection piece, thereby facilitating the replacement of the detection piece.
