[0001] The present invention relates to the technical field of vehicle brake system detection equipment, in particular to a rail transit vehicle brake system detection equipment. Background Art

[0002] Rail transit vehicle brake system testing equipment is a tool and equipment specifically used to test and evaluate the performance of the brake system of rail transit vehicles (such as subways, trams, light rails, etc.). These devices can help ensure that the vehicle's brake system can work effectively, protect passenger safety, and meet relevant regulations and safety standards. The brake system is a vital part of railways and urban rail transit.

[0003] For example, the "A safety detection device for a railway vehicle braking system" with publication number CN208076170U includes a protective shell and a device body, the outer surfaces of both ends of the protective shell are fixedly mounted with reinforcement plates, and the inner surface of the front end of the reinforcement plate is fixedly mounted with reinforcement holes, the outer surface of the front end of the protective shell is provided with a movable door, and the outer surface of the front end of the movable door is provided with a hinge near one side, the inner surface of the front end of the movable door is fixedly mounted with a door handle near the other side, and the inner surface of the front end of the movable door is fixedly mounted with a door lock near the door handle.

[0004] In the prior art, although this type of brake system detection equipment can prevent external rain from affecting the normal operation of the equipment and is suitable for different working conditions, it is lacking in the adjustment and replacement of the detection head in the detection equipment. Since this type of detection equipment does not have a structure for replacing or adjusting the detection head, this will result in this type of detection equipment being able to only detect the brake caliper of the rail vehicle through one detection head. When it is necessary to detect brake calipers of different models or sizes, this type of detection equipment cannot be flexibly adjusted according to different models of brake calipers, thereby reducing the adaptability of the detection equipment and also reducing the detection efficiency of the brake caliper.

[0016] Preferably, one end of the torsion spring is connected to the side of the material guide plate, and the other end is connected to the inner surface of the base.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When in use, the brake clamp is transported by a conveyor belt, and then the motor A drives the gear A to rotate. When the gear A rotates, it drives the U-shaped frame to slide inside the base through the rack, thereby driving the limit plate to limit and clamp the brake clamp. At this time, turn on the motor B, and the motor B will drive the screw rod A to rotate. When the screw rod A rotates, it will drive the slider to slide inside the bracket, thereby driving the gear B and the crossbeam to move downward. At this time, the crossbeam will drive the laser displacement sensor to move. After the laser displacement sensor moves to the brake clamp, the brake clamp can be tested. After the key dimensions of the brake clamp are tested, the electric push rod B drives the connecting block to move inside the bracket. At this time, the connecting block drives the tooth plate to move. After the tooth plate moves to the position where it fits the gear B, it can be moved through the screw rod A. The rotation of the slider drives the gear B and the beam to move upward, and the electric push rod A drives the push block to slide out of the slider. When the gear B touches the tooth plate, the gear B drives the beam to rotate. After the ultrasonic flaw detection probe on the beam rotates to the bottom of the beam, the electric push rod A drives the push block to be inserted into the slider. After the beam is fixed, the electric push rod B drives the connecting block and the tooth plate away from the gear B. At this time, the beam and the ultrasonic flaw detection probe can be moved downward by the rotation of the screw rod A, so as to detect the inside of the brake caliper. The rotating design of the beam first uses the laser displacement sensor to measure the key size of the brake caliper, and then uses the ultrasonic flaw detection probe to check whether there are defects such as cracks in its internal structure, thereby improving the detection efficiency and comprehensiveness of the detection equipment.

[0019] 2. When in use, the motor A drives the gear C to rotate. When the gear C rotates, it drives the gear D to rotate through the toothed chain. The gear D drives the gear E to rotate through the transmission shaft. When the gear E rotates, it drives the screw B to rotate through the gear F, thereby driving the baffle to slide on the surface of the limit rod. After the baffle is lifted from the base, the brake clamp can be tested. When the motor A drives the gear A to rotate so that the limit plate clamps the brake clamp, the baffle is lifted synchronously, thereby avoiding the situation that the staff's head is hit due to the downward movement of the crossbeam when the brake clamp is tested. At the same time, it also avoids the abnormal increase of energy output due to the failure of the ultrasonic flaw detection probe or the operator's operating error, or the operator's long-term close contact with the high-energy output probe, which causes certain adverse effects on the human body, thereby improving the safety of the detection equipment;

[0020] 3. When in use, after the brake caliper is inspected by the ultrasonic flaw detection probe, the conveyor belt will transport the inspected brake caliper to the push plate. At this time, the brake caliper with abnormal detection will be pushed to the guide rack by the electric push rod C, and the brake caliper with normal detection will be guided to the conveyor rack through the guide plate. When the guide plate guides the brake caliper, the guide plate rotates downward under the influence of the gravity of the brake caliper, and the guide plate is also rotated upward by the torsion of the torsion spring, thereby buffering the fall of the brake caliper. After the brake caliper falls onto the conveyor rack, the guide plate is rotated to the initial position by the torsion spring to facilitate the guiding of the next batch of brake calipers. The design of the push plate and the guide plate not only sorts the brake calipers after detection, but also buffers the fall of the brake caliper with normal detection, thereby avoiding the secondary damage of the brake caliper after detection due to bumps.

[0035] In this embodiment, the brake clamp is transported by the conveyor belt 102, and then the motor A103 drives the gear A104 to rotate. When the gear A104 rotates, it drives the U-shaped frame 105 to slide inside the base 100 through the rack 106, thereby driving the limit plate 107 to limit and clamp the brake clamp. At this time, the motor B108 is turned on, and the motor B108 drives the screw rod A109 to rotate. When the screw rod A109 rotates, it drives the slider 110 to slide inside the bracket 101, thereby driving the gear B111 and the crossbeam 112 to move downward. At this time, the crossbeam 112 drives the laser displacement sensor 116 to move. After the laser displacement sensor 116 moves to the brake clamp, the brake clamp can be detected;

[0036] After the key dimensions of the brake caliper are detected, the electric push rod B125 drives the connecting block 126 to move inside the bracket 101.

[0040] Embodiment 3: According to Figure 10-11 As shown, a conveying frame 300 is arranged on the side of the base 100, an electric push rod C301 is fixedly installed on the surface of the base 100, a push plate 302 is installed on the output end of the electric push rod C301, a material guide frame 303 is fixedly installed on the back of the base 100, a rotating rod 304 is rotatably connected inside the base 100, a torsion spring 305 is sleeved on the surface of the rotating rod 304, the material guide frame 303 is fixedly installed on one end of the rotating rod 304, a roller 307 is rollingly connected inside the base 100, the push plate 302 is slidably connected to the base 100, the push plate 302 is slidably connected to the conveyor belt 102, the surface of the material guide frame 303 is an inclined surface, one end of the torsion spring 305 is connected to the side of the material guide plate 306, and the other end is connected to the inner surface of the base 100.

[0041] In this embodiment, after the brake caliper is inspected by the ultrasonic flaw detection probe 115, the conveyor belt 102 will transport the inspected brake caliper to the push plate 302. At this time, the brake caliper with abnormal detection will be pushed to the guide frame 303 by the push plate 302 driven by the electric push rod C301, and the brake caliper with normal detection will be guided to the conveyor frame 300 through the guide plate 306. When the guide plate 306 guides the brake caliper, it rotates downward under the influence of the gravity of the brake caliper, and the guide plate 306 is also affected by The push plate 302 and the guide plate 306 are designed to not only sort the brake calipers after inspection, but also to cushion the drop of the brake calipers that have been inspected normally, thereby avoiding the brake calipers from being damaged again after inspection due to bumps.

[0042] The use method and working principle of this device: when the brake caliper needs to be tested, the brake caliper only needs to be placed on the surface of the conveyor belt 102. At this time, the conveyor belt 102 will transport the brake caliper, and then the motor A103 will drive the gear A104 to rotate. When the gear A104 rotates, it will drive the U-shaped frame 105 to slide inside the base 100 through the rack 106, thereby driving the limit plate 107 to limit and clamp the brake caliper. At this time, the motor B108 is turned on, and the motor B108 will drive the screw rod A109 to rotate. When the screw rod A109 rotates, it will drive the slider 110 to slide inside the bracket 101, thereby driving the gear B111 and the beam 112 to move downward. At this time, the beam 112 will drive the laser displacement sensor 116 to move. After the laser displacement sensor 116 moves to the brake caliper, the brake caliper can be tested;

[0043] After the key dimensions of the brake caliper are detected, the electric push rod B125 drives the connecting block 126 to move inside the bracket 101. At this time, the connecting block 126 drives the tooth plate 127 to move. After the tooth plate 127 moves to the position where the gear B111 is in contact, the screw rod A109 can be rotated to make the slider 110 drive the gear B111 and the beam 112 to move upward.

After the ultrasonic flaw detection probe 115 on the beam 112 rotates to the position of the beam 112, the ultrasonic flaw detection probe 115 on the beam 112 rotates to the position of the beam 112. After the bottom surface is reached, the electric push rod A113 drives the push block 114 to be inserted into the slider 110. After the cross beam 112 is fixed, the electric push rod B125 drives the connecting block 126 and the tooth plate 127 away from the gear B111. At this time, the cross beam 112 and the ultrasonic flaw detection probe 115 can be moved downward by rotating the screw rod A109, so as to detect the inside of the brake caliper. The rotating design of the cross beam 112 first uses the laser displacement sensor 116 to measure the key size of the brake caliper, and then uses the ultrasonic flaw detection probe 115 to check whether there are defects such as cracks in its internal structure, thereby improving the detection efficiency and comprehensiveness of the detection equipment;

[0044] When the ultrasonic flaw detection probe 115 needs to be replaced, the ultrasonic flaw detection probe 115 only needs to be pushed downward, and the ultrasonic flaw detection probe 115 will drive the block C124 to move downward. After the block C124 moves to the bottom of the block B118, the ultrasonic flaw detection probe 115 can be lifted upward. At this time, the block C124 will slide out of the crossbeam 112 along the arc surface of the bottom surface of the block B118, thereby completing the disassembly of the ultrasonic flaw detection probe 115. After completion, insert the ultrasonic flaw detection probe 115 of different models into the crossbeam 112. At this time, the block C124 will be affected by the arc surface of the top surface of the block A117 and slide to the two sides of the ultrasonic flaw detection probe 115. After the block C124 moves to the bottom surface of the block A117, the block C124 will be affected by the elastic force of the spring B123 and slide to the middle of the block A117, thereby fixing the ultrasonic flaw detection probe 115. At this time, the replacement of the ultrasonic flaw detection probe 115 can be completed.

[0045] Before testing the brake caliper, turn on the motor A103 first. The motor A103 will drive the gear C200 to rotate. When the gear C200 rotates, it will drive the gear D202 to rotate through the toothed chain 201. The gear D202 will drive the gear E204 to rotate through the transmission shaft 203. When the gear E204 rotates, it will drive the screw B206 to rotate through the gear F205, thereby driving the baffle 207 to slide on the surface of the limit rod 208. After the baffle 207 rises from the base 100, the brake caliper can be tested. The motor A103 drives the gear A103 to rotate. 04 rotates to make the limit plate 107 clamp and limit the brake clamp, and at the same time, the baffle 207 is raised synchronously, so as to avoid the worker's head being hit due to the downward movement of the crossbeam 112 when the brake clamp is tested. At the same time, it also avoids the abnormal increase of energy output due to the failure of the ultrasonic flaw detection probe 115 or the operator's operating error, or the operator's long-term close contact with the high-energy output probe, which causes certain adverse effects on the human body, thereby improving the safety of the detection equipment;

[0046] When the brake calipers need to be sorted, the brake calipers are first inspected by the ultrasonic flaw detection probe 115, and the conveyor belt 102 will transport the inspected brake calipers to the push plate 302. At this time, the brake calipers with abnormal detection will be pushed to the guide rack 303 by the push plate 302 driven by the electric push rod C301, and the brake calipers with normal detection will be guided to the conveyor rack 300 by the guide plate 306. When the guide plate 306 guides the brake calipers, it rotates downward under the influence of the gravity of the brake calipers, and at the same time, the guide plate 306 06 will also be rotated upward by the torsion force of the torsion spring 305, thereby cushioning the fall of the brake caliper. After the brake caliper falls onto the conveyor rack 300, the guide plate 306 will be rotated to the initial position by the torsion spring 305 to facilitate the guidance of the next batch of brake calipers. The design of the push plate 302 and the guide plate 306 not only sorts the brake calipers after inspection, but also cushions the fall of the brake calipers that have been inspected normally, thereby avoiding the brake caliper from being damaged again after inspection due to bumps.
