Description

Technical Field

[0001] The utility model belongs to the technical field of circuit detection, in particular to a track circuit detection device. Background Art

[0002] With the rapid development of modern transportation, people are gradually replacing traditional modes of travel with new means of transportation to reach areas that are beyond human reach. Rail transit is the best of these means of transportation. It is favored by the majority of travelers because of its convenience, wide coverage, and affordability. In order to ensure the safe passage of rail transit, maintenance and inspection are required after long-term use.

[0003] A track circuit is a circuit composed of a section of steel rail as a conductor. It is used to continuously detect whether a section of the line is occupied by a locomotive or vehicle. It is also used to control signal devices or switch devices to ensure driving safety.

[0004] In the existing technology, the detection device workers need to hold the detection instrument in one hand and the caliper in the other hand. At this time, it is impossible to record the test results. The existing technology lacks a fixing device for the detection instrument, and different instruments have different fixing devices. The same fixing device cannot be used for different instruments; the existing caliper structure is also difficult to use for rails of different models and specifications. Utility Model Content

[0005] In view of this, the present invention aims to provide a track circuit detection device to solve the problems in the prior art that the detection instrument cannot be fixed and the detection caliper cannot be applied to rails of different models and specifications.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0007] A track circuit detection device includes a caliper adjustment assembly, a connecting assembly, an instrument fixing assembly, and a handle. The bottom of the caliper adjustment assembly is connected to the top of the instrument fixing assembly through the connecting assembly, and the handle is provided at the bottom of the instrument fixing assembly.

[0008] The caliper adjustment assembly includes a base plate, a first caliper, a second caliper, two telescopic assemblies, and a pulling rope. The bottom of the base plate is arranged on the top of the connecting assembly. The top of the base plate is provided with a first slide groove. The bottom of the first caliper is provided with a first slider corresponding to the first slide groove. The bottom of the second caliper is provided with a second slider corresponding to the first slide groove. The first caliper is slidably arranged at one end of the first slide groove by the first slider, and the second caliper is slidably arranged at the other end of the first slide groove by the second slider.

[0009] The first caliper and the second caliper are electrically connected to the meter;

[0010] Two telescopic components are arranged at both ends of the first slide groove, and the two telescopic components are connected to the first slider and the second slider respectively;

[0011] One end of the pulling rope is connected to the first slider and the second slider, and the other end of the pulling rope extends into the interior of the connecting component.

[0012] Furthermore, a through hole is provided at the bottom center of the bottom plate, which is connected to the first slide groove and the interior of the connecting assembly. The through hole can allow the pulling rope to pass through.

[0013] Furthermore, the width of the first sliding groove is smaller than the width of the first caliper and the second caliper.

[0014] Furthermore, the telescopic assembly includes a telescopic outer tube, a telescopic inner tube, and a spring. The telescopic inner tube is telescopically arranged inside the telescopic outer tube. An end of the telescopic outer tube away from the telescopic inner tube is connected to the side wall of the first chute. An end of the telescopic inner tube away from the telescopic outer tube is connected to the first slider or the second slider.

[0015] The spring is arranged inside the telescopic outer tube and the telescopic inner tube, one end of the spring is connected to the side wall of the first sliding groove, and the other end of the spring is connected to the first slider or the second slider.

[0016] The first caliper and the second caliper can slide in the first slide groove through the first slider and the second slider, and the telescopic component guides the first slider and the second slider; by pulling the pulling rope, the first slider and the second slider move toward each other, and by loosening the pulling rope, the first slider and the second slider move away from each other under the action of the rebound force of the spring, so as to adjust the distance between the first caliper and the second caliper, so as to adapt to different models and specifications of rails.

[0017] Furthermore, the connecting assembly includes a connecting pipe and a bolt, the top of the connecting pipe is connected to the bottom of the base plate, and the bottom of the connecting pipe is connected to the top of the instrument fixing assembly;

[0018] The side wall of the connecting pipe is provided with a first bolt hole, the bolt is threadedly arranged on the connecting pipe through the first bolt hole, the bolt is provided with a first limiting plate and a second limiting plate, and the first limiting plate and the second limiting plate are arranged inside the connecting pipe.

[0020] When it is necessary to reduce the distance between the first caliper and the second caliper, the bolt is rotated to wrap the pulling rope around the bolt. Under the traction force of the pulling rope, the first slider and the second slider are moved in the direction of approaching each other, thereby causing the first caliper and the second caliper to move in the direction of approaching each other, and the first caliper and the second caliper are used to clamp the rail and complete the circuit test. After the test is completed, the bolt is rotated in the opposite direction to release the pulling rope from the bolt. After the traction force of the pulling rope disappears, under the action of the rebound force of the spring, the first slider and the second slider will move in the direction of moving away from each other, thereby causing the first caliper and the second caliper to move in the direction of moving away from each other, thereby releasing the clamping of the rail.

[0021] The first limiting plate and the second limiting plate can play a limiting role, so that the pulling rope is wound between the first limiting plate and the second limiting plate.

[0022] Furthermore, the instrument fixing assembly includes a first mounting plate, a second mounting plate, a first fixing plate, and a second fixing plate. A second slide groove is provided on the top of the first mounting plate, the second mounting plate is slidably arranged inside the second slide groove, the first fixing plate is arranged on the bottom outer surface of the first mounting plate, and the second fixing plate is arranged on the top outer surface of the second mounting plate.

[0024] Furthermore, a first positioning groove is provided on the top of the first fixing plate, and a second positioning groove is provided on the bottom of the second fixing plate.
