Description

Technical Field

[0001] The invention relates to the technical field of railway signal circuit detection, in particular to an insulation detection device used for railway signal circuits. Background Art

[0002] With the continuous development of our country, railway travel has become an indispensable way of life in people's daily life. The use of railways has brought great convenience to people's travel. A large number of signal circuits will be used in the use of railways, and in order to ensure their normal operation, insulation detection equipment is required to perform daily detection and maintenance of the circuit.

[0003] Existing testing equipment usually uses two test pens of a multimeter to continuously measure multiple points on the rail for insulation testing. During the test, a person needs to squat on one side of the track and then move on the track while squatting, which is inconvenient and inconvenient to fix the test points, which is prone to poor contact.

[0004] At the same time, when the existing SICO2046 online tester performs insulation testing, it uses a signal generator and a signal receiver to be put on the outside of the rail through a hose, and a voltage sensing sheet is placed between the two for testing. When installing the device, personnel are also required to squat for installation testing and plug and fix the hose. Due to the inconvenience of observation, stones with smaller diameters under the rails are easy to enter the hose joint, and the stones are easy to damage the hose joint during plugging. The installation process is inconvenient, and after testing one test point, the device needs to be disassembled and then moved to the next test point for installation testing. The test personnel are required to squat and stand up repeatedly, which is easy to aggravate the pain of the test personnel with bad waists, and it is inconvenient to use. Summary of the invention

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The signal generator, signal receiver and voltage sensing sheet are easy to install and disassemble through the card frame and buckle, so that they can be placed on the rail synchronously for easy operation. The No. 1 roller supports the fixed component when it moves to another rail, so that when the personnel pushes the handle, the No. 1 roller rotates, driving the fixed component on the other rail to move, thereby maintaining the overall stability of the detection equipment when detecting another rail.

[0036] 2. The No. 2 motor runs, driving multiple flaps to flip downward, flipping the push assembly and the hose stuck inside the holder to the two sides under the rail. The No. 3 motor runs, causing the No. 3 rack to slide inside the No. 3 fixed frame, pushing the hose connector to plug in, so that the inspectors can install and disassemble the inspection equipment while standing, replacing the repeated squatting and standing for installation and inspection, reducing the pain of inspectors with bad waists, speeding up the installation and disassembly of the inspection equipment, and making the inspection equipment easy to use.

[0037] 3. When the hose connector moves, the No. 1 and No. 2 pressure plates push downward to squeeze the stones on the hose plug-in path. The No. 2 pressure plate first presses against the No. 1 mounting frame to flip the No. 2 pressure plate downward, and then presses the No. 1 pressure plate to flip the No. 1 pressure plate downward, exposing the plug-in paths at both ends of the hose for plugging. This prevents the stones from entering the hose connector when it is plugged in, thereby preventing the stones from entering the hose connector and damaging the hose connector due to inconvenience in observation.

[0038] 4. When detecting another rail, the inspector does not cross the track. Instead, he flips the rail so that the support rod at the other end of the rail contacts the ground. The No. 1 motor starts to drive the pull rope to rotate on the roller surface, so that the pull rope drives the slider to slide inside the rail, and the fixed component is moved to the other rail. In this way, the insulation of the other rail can be tested without crossing the track, thereby improving the safety of the inspectors and reducing potential safety hazards.

The No. 3 motor 502 runs, drives the No. 3 gear 505 to rotate, and through the meshing transmission of the No. 3 gear 505 and the No. 3 rack 503, the No. 3 rack 503 slides inside the No. 3 fixing frame 501, pushing the hose 703 connector to be plugged in, so that the inspection personnel can install and disassemble the inspection equipment while standing, instead of repeatedly squatting and standing for installation and inspection, reducing the pain of the inspection personnel with bad waists, speeding up the installation and disassembly of the inspection equipment, and making the inspection equipment easy to use.

[0059] like Figure 7-9 As shown, in this embodiment, the protective component 6 includes: a No. 1 mounting frame 601 is fixedly installed on a side surface of a card seat 504, a No. 2 mounting frame 602 is fixedly installed on a side surface of another card seat 504, a No. 1 pressure plate 603 is rotatably connected to the inside of the No. 1 mounting frame 601, and a No. 2 pressure plate 606 is rotatably connected to the inside of the No. 2 mounting frame 602; one end of the No. 1 pressure plate 603 and the No. 2 pressure plate 606 are fixedly connected to a coil spring 604 that can reset them, and a limit block 605 that limits the rotation of the No. 1 pressure plate 603 is fixedly installed on the inner surface of the No. 1 mounting frame 601.

[0061] Embodiment 2

[0062] On the basis of the first embodiment, in order to make up for the problem that the inspectors in the first embodiment cross between the tracks to inspect the rails, there are certain potential safety hazards.

[0064] During specific implementation, when another rail is detected, the inspector does not cross the track, but flips the slide rail 201 so that the support rod at the other end of the slide rail 201 contacts the ground to provide auxiliary support for the slide rail 201. At this time, the handle 101 and the slide rail 201 are L-shaped, and the No. 1 motor 208 runs, driving the pull rope 209 to rotate on the surface of the roller 207, so that the pull rope 209 drives the slider 202 to slide inside the slide rail 201, and the fixed component 3 is moved to the other rail. At this time, the handle 101 is pulled upward to make the slide rail 201 in an inclined state, so that the No. 2 roller 307 is in contact with the top of the other rail, and the height of one end of the slide rail 201 with the support rod is lifted to separate the support rod from the ground to ensure that the slide rail 201 can be pushed, thereby performing insulation testing on the other rail without the personnel crossing the track, thereby improving the safety of the inspectors and reducing safety hazards.
