Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a testing and maintenance device for tracked vehicles. Background Technology

[0002] Tracked vehicles are vehicles that use tracks as their moving mechanical structure. During operation, they rely on the friction between the tracks and the ground to propel themselves. Because of their large contact area with the ground and the resulting high friction, tracked vehicles are widely used on complex terrains, such as mountainous areas. Since tracked vehicles are less prone to slipping, they exhibit very high stability during movement. Tracked vehicles have a wide range of applications in practice, such as tanks for military use and excavators for construction.

[0003] Tracked vehicles frequently travel on complex terrains such as muddy or wet surfaces, generating significant vibrations that can alter the airtightness of the gearbox. Therefore, during the inspection and maintenance of tracked vehicles, it is often necessary to perform an airtightness test on the multi-gearbox assembly. The test involves placing the gearbox assembly on a test bench, removing one of the two rubber stoppers from the top of the gearbox while leaving the other sealed, pressing the air pump nozzle into the open stopper, and then adding air into the gearbox. The test is then conducted using a testing instrument. If there is no leakage, the light in the center of the instrument illuminates; if there is leakage, the lights on either side of the instrument illuminate.

[0004] In existing technologies, the air nozzle is usually pressed directly into the filler neck. However, if the installation is not done properly, there may be a gap between the air nozzle and the filler neck, which will affect the accuracy of the test results. Utility Model Content

[0005] The purpose of this invention is to provide a tracked vehicle inspection and maintenance device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A tracked vehicle inspection and maintenance device includes an inspection platform with support legs fixedly connected to the bottom. A gearbox is placed on top of the inspection platform, and two refueling pipes are fixedly connected to the top of the gearbox. Rubber stoppers are inserted into the top of the refueling pipes. Clamping mechanisms are provided on both sides of the gearbox, and an inspection mechanism is provided above the gearbox. The inspection mechanism includes a horizontal plate, and a conical air nozzle with the small end facing down is fixedly connected to the bottom of the horizontal plate. An air bladder is fixedly connected to the outer periphery of the air nozzle. An air supply assembly is also provided on the horizontal plate. After the air nozzle is inserted into the refueling pipe to a certain depth, the air bladder is inflated by the air supply assembly.

[0008] Preferably, the air nozzle has an air supply chamber that communicates with the airbag inside its wall, and the top of the horizontal plate has an air supply hole that communicates with the air supply chamber.

[0009] Preferably, the air supply assembly includes a cylinder fixedly connected to the top of the horizontal plate, a piston plate slidably connected between the inner walls of the cylinder, a piston rod fixedly connected to the bottom of the piston plate, the bottom end of the piston rod extending out of the horizontal plate and fixedly connected to an abutment plate, a spring fixedly connected between the abutment plate and the horizontal plate, the spring being wound around the outer circumference of the piston rod, a delivery pipe fixedly connected between the top of the cylinder and the horizontal plate, the delivery pipe communicating with an air supply hole opened at the top of the horizontal plate, the piston plate dividing the inner part of the cylinder into an upper chamber and a lower chamber, and a vent hole opened on the side wall of the cylinder, the vent hole communicating with the lower chamber of the cylinder.

[0010] Preferably, the testing mechanism also includes a frame fixedly connected to the top of the testing platform, on which an mounting plate is slidably mounted; a hydraulic cylinder is slidably connected to the mounting plate from side to side, a horizontal plate is fixedly connected to the bottom of the hydraulic cylinder, a detector is placed on the top of the testing platform, an air pipe is fixedly connected to the detector, the other end of the air pipe is fixedly connected to the side wall of the horizontal plate, and the air nozzle is connected to the air pipe.

[0011] Preferably, a first indicator light and a second indicator light are provided on the front side of the detector, with the second indicator light located on both sides of the first indicator light.

[0012] Preferably, the clamping mechanism includes a clamping motor fixedly connected to one side of the testing table. The output end of the clamping motor is connected to a bidirectional lead screw via a coupling. The top of the testing table has a mounting groove. The bidirectional lead screw is rotatably connected in the mounting groove. Two symmetrically arranged sliders are threaded onto the bidirectional lead screw. The sliders are slidably connected in the mounting groove. The top of the sliders extends out of the testing table. A clamping plate is fixedly connected to the side of the two sliders that are close to each other. A gearbox is placed between the two clamping plates.

[0013] Preferably, sponge is fixedly connected to the side of the two clamps that are close to each other.

[0014] The beneficial effects are as follows: After the air nozzle is inserted into the refueling pipe to a certain depth, air is inflated into the airbag through the air supply component, causing the airbag to bulge. As the air nozzle continues to move downward, the inner wall of the refueling pipe squeezes the airbag, flattening the part of the airbag inside the refueling pipe. The inner wall of the refueling pipe and the side wall of the air nozzle press tightly together to seal. At the same time, the refueling pipe pushes the gas in the lower part of the airbag into the upper part of the airbag. The expansion of the upper part of the airbag further seals the gap between the refueling pipe opening and the air nozzle, improving the sealing performance between the air nozzle and the refueling pipe, thereby improving the accuracy of the test results.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-5 As shown, a tracked vehicle inspection and maintenance device includes an inspection platform 1. A support leg 101 is fixedly connected to the bottom of the inspection platform 1. A gearbox 2 is placed on the top of the inspection platform 1. Two oil filling pipes 201 are fixedly connected to the top of the gearbox 2. The top of the oil filling pipes 201 is plugged with rubber stoppers. During inspection, one of the sealing stoppers is removed, so that one oil filling pipe 201 is in an open state and the other oil filling pipe 201 is in a blocked state.

[0027] Gearbox 2 is equipped with clamping mechanisms on both sides. The clamping mechanism includes a clamping motor 301 bolted to one side of the testing table 1. The output end of the clamping motor 301 is connected to a double-acting lead screw 302 via a coupling. The top of the testing table 1 is provided with a mounting groove. The double-acting lead screw 302 is rotatably connected in the mounting groove. Two symmetrically arranged sliders 303 are threaded onto the double-acting lead screw 302. The sliders 303 are slidably connected in the mounting groove. The top of the sliders 303 extends out of the testing table 1. A clamping plate 304 is fixedly connected to the side of the two sliders 303 that are close to each other. Gearbox 2 is placed between the two clamping plates 304. A sponge 305 is fixedly connected to the side of the two clamping plates 304 that are close to each other. The sponge 305 prevents wear on gearbox 2 during clamping.

[0028] A detection mechanism is installed above the gearbox 2. The detection mechanism includes a horizontal plate 403, and a conical air nozzle 404 with its small end facing downwards is fixedly connected to the bottom of the horizontal plate 403. The detection mechanism also includes a frame 401 bolted to the top of the detection platform 1. A mounting plate 4011 is slidably mounted on the frame 401. A hydraulic cylinder 402 is slidably connected to the mounting plate 4011. The horizontal plate 403 is fixedly connected to the bottom of the hydraulic cylinder 402. A detector 405 is placed on the top of the detection platform 1. An air pipe 406 is fixedly connected to the detector 405. The other end of the air pipe 406... Fixedly connected to the side wall of the horizontal plate 403, the air nozzle 404 is connected to the air pipe 406. The front side of the detector 405 is provided with a first indicator light 4051 and a second indicator light 4052. The second indicator light 4052 is located on both sides of the first indicator light 4051. The detector 405 can be inflated into the gearbox 2 through the air nozzle 404. After the test, if the first indicator light 4051 is lit, it means that the gearbox 2 is airtight and has good air tightness. If the second indicator light 4052 is lit, it means that the gearbox 2 is airtight and has poor air tightness. The detector 405 adopts existing technology, which will not be described in detail.

[0029] An air bladder 501 is fixedly connected to the outer periphery of the air nozzle 404. An air supply chamber communicating with the air bladder 501 is opened in the inner wall of the air nozzle 404. An air supply hole communicating with the air supply chamber is opened at the top of the horizontal plate 403.

[0030] An air supply assembly is also provided on the horizontal plate 403. After the air nozzle 404 extends into the refueling pipe 201 to a certain depth, the air supply assembly inflates the airbag 501. The air supply assembly includes a cylinder 502 fixedly connected to the top of the horizontal plate 403. A piston plate 503 is slidably connected between the inner walls of the cylinder 502. A piston rod 504 is fixedly connected to the bottom of the piston plate 503. The bottom end of the piston rod 504 extends out of the horizontal plate 403 and is fixedly connected to an abutment plate 505. A spring 506 is fixedly connected between 505 and the horizontal plate 403. The spring 506 is wrapped around the outer circumference of the piston rod 504. A delivery pipe 507 is fixedly connected between the top of the cylinder 502 and the horizontal plate 403. The delivery pipe 507 is connected to the air supply hole opened on the top of the horizontal plate 403. The piston plate 503 divides the interior of the cylinder 502 into an upper chamber and a lower chamber. A vent hole for air inlet and outlet is opened on the side wall of the cylinder 502. The vent hole is connected to the lower chamber of the cylinder 502.

[0031] Working principle: In use, place the gearbox 2 on the testing table 1 and open one of the oil filling pipes 201. Manually push the air nozzle 404 and the mounting plate 4011 to adjust the position of the air nozzle 404 on the frame 401 so that the air nozzle 404 is directly above the opened oil filling pipe 201. Start the clamping motor 301, which drives the double-acting screw 302 to rotate. The double-acting screw 302 drives the two sliders 303 to move the clamping plates 304 closer to each other until the clamping plates 304 and the sponge 305 clamp the gearbox 2. Then, turn off the clamping motor 301. Control the hydraulic cylinder 402 to move the horizontal plate 403 downwards, causing the air nozzle 404 to move downwards. After 404 extends into the refueling pipe 201 to a certain depth, the abutment plate 505 abuts against the gearbox 2. As the horizontal plate 403 continues to descend, the piston plate 503 gradually moves upward along the cylinder body 502, squeezing the gas in the cylinder body 502 into the air bladder 501 through the delivery pipe 507, inflating the air bladder 501 and filling the gap between the air nozzle 404 and the refueling pipe 201. At this time, the control hydraulic cylinder 402 continues to drive the air nozzle 404 downward through the horizontal plate 403. The air bladder 501, in conjunction with the conical sidewall of the air nozzle 404, drives the hydraulic cylinder 402 to slide and fine-tune its position on the frame 401, making the air nozzle 404 and the refueling pipe 201 coaxial. As the nozzle 404 continues to move downward, the inner wall of the refueling pipe 201 compresses the airbag 501, flattening the portion of the airbag 501 inside the refueling pipe 201. The inner wall of the refueling pipe 201 and the side wall of the nozzle 404 press tightly together to seal. At the same time, the refueling pipe 201 pushes the gas in the lower part of the airbag 501 into the upper part of the airbag 501. The upper part of the airbag 501 expands, further sealing the gap between the nozzle 404 and the refueling pipe 201, thus improving the sealing performance between the nozzle 404 and the refueling pipe 201.

[0032] Next, air is added to the gearbox 2 through the air pipe 406 to test the air tightness of the gearbox 2. After the test, if the first indicator light 4051 is on, it means that the gearbox 2 is not leaking and has good air tightness. If the second indicator light 4052 is on, it means that the gearbox 2 is leaking and has poor air tightness, requiring maintenance. After the test, the hydraulic cylinder 402 drives the horizontal plate 403 to move the air nozzle 404 upward. The abutment plate 505, under the elastic force of the spring 506, drives the piston plate 503 downward, drawing the gas in the air bag 501 into the cylinder 502, thus facilitating the removal of the air nozzle 404 from the filling pipe 201.
