Description

Technical Field

[0001] This invention relates to the field of wear detection technology, specifically to a material wear detection device based on rail transit. Background Technology

[0002] In rail transit, brake pads are usually used in conjunction with braking mechanisms to reduce vehicle speed and stop. As a core component of the rail transit braking system, the wear of brake pads directly affects driving safety. During inspection, key indicators such as thickness and abnormal wear should be focused on. Using a laser measuring instrument to detect the thickness of worn brake pads is a conventional method. However, existing material wear detection equipment has the following problems when used.

[0003] Existing material wear testing equipment mostly involves fixing brake pads, simulating braking using calipers and other mechanisms, and then using a laser measuring instrument to measure the thickness of the worn brake pads to determine their compliance. However, existing equipment is not suitable for stably positioning and fixing brake pads of different specifications, and mostly uses a unidirectional positioning method. This makes it easy for the brake pads to deviate during rotational braking, affecting the testing accuracy. Furthermore, braking generates debris and high temperatures, and existing equipment cannot stably cool and clean brake pads of different specifications. Debris can affect the testing results. Additionally, the temperature during continuous testing is generally higher than the normal operating temperature, which can affect material properties. If this factor is not mitigated, testing accuracy cannot be guaranteed.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a material wear detection device based on rail transit to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material wear detection device based on rail transit, comprising a detection base, a detection frame fixed on the top of the detection base, and a control box fixed inside the top of the detection frame;

[0007] It also includes a vertical electric slide rail, which is fixed at the lower right position inside the test frame. A test clamp is installed on the vertical electric slide rail via a first hydraulic rod. A mounting base is installed at the top center of the test base via a motor. A mounting column is fixed at the top of the mounting base. A receiving plate is sleeved in the middle of the mounting column. A positioning component is provided inside the mounting column.

[0008] The second hydraulic rod is fixed to the bottom of the control box. The bottom output end of the second hydraulic rod is connected to a mounting plate. A laser measuring instrument is connected to the lower left side of the mounting plate via a horizontal electric slide rail. A cleaning and cooling component is set at the lower right side of the mounting plate. An adjustment component is set on the left side of the cleaning and cooling component.

[0009] Preferably, the positioning component includes an electric push rod, which is embedded in the cavity inside the mounting column. A push head is fixed to the top output end of the electric push rod, and a crossbar is provided on the outer side of the top of the push head. The crossbar is slidably disposed inside the mounting column by means of a spring. A positioning block is fixed to the outer end of the crossbar, and the positioning block is located on the outer side of the mounting column. A guide rod is fixed to the top of the push head, and the top of the guide rod extends out of the top of the mounting column.

[0010] Preferably, the top outer side of the pusher head is designed as a sloping structure, and the sloping surface of the top outer side of the pusher head is parallel and attached to the bottom sloping surface of the inner end of the crossbar.

[0011] Preferably, the crossbars are distributed at equal angles within the mounting column, and the cross-section of the positioning block on the outer side of the crossbar is designed as a right-angled trapezoidal structure, with the outer inclined surface of the positioning block inclined inward.

[0012] Preferably, the cleaning and cooling assembly includes a mounting frame, which is laterally slidably disposed in the bottom cavity of the mounting plate via an elastic telescopic rod. A blower head is rotatably mounted in the bottom cavity of the mounting frame. A first gear is fixed to the front side of the blower head, and a second gear meshes with the bottom of the first gear. Both the second gear and the first gear are rotatably mounted in the bottom cavity of the mounting frame. A rack meshes with the bottom of the second gear, and the rack is laterally slidably disposed inside the bottom of the mounting frame via a spring.

[0013] Preferably, the blower head has an overall "L" shaped structure design, with the bottom of the blower head blowing air outwards, and the blower head is connected to an external fan via a flexible hose.

[0014] Preferably, the adjustment assembly includes a vertical rod that slides through the bottom of the mounting plate via a spring, with the top of the vertical rod located within an adjustment groove, which is formed within the mounting frame.

[0015] Preferably, the bottom of the vertical rod corresponds to the top of the guide rod, and the right side of the adjustment groove is designed as an inclined structure.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this invention, multiple positioning blocks are set up. The push head is driven to move up by an electric push rod, and the positioning blocks are moved outward by a crossbar. The inclined structure on the outside of the positioning blocks provides positioning support for the brake pads from the inside. At the same time, the receiving plate applies a vertical pressure to the brake pads, which helps to improve the tight fixing effect. During the detection process of rotating the brake pads by the mounting column, it helps to improve the positioning strength, avoid deviation, and thus help to improve the detection accuracy.

[0018] 2. In this invention, based on the size of the brake pad, the pusher moves upward, causing the guide rod to move upward. During the detection process of the mounting plate descending, the vertical rod contacts the guide rod and moves upward passively. This, in conjunction with the adjustment groove, adjusts the lateral position of the mounting bracket, thereby adjusting the initial position of the blower head. This ensures sufficient airflow to cool and clean the brake pads. Simultaneously, in conjunction with the rack, first gear, and second gear, the angle of the blower head is adjusted synchronously. This allows the blower head to travel a greater distance when dealing with larger brake pads, providing good cleaning and cooling effects for brake pads of different specifications. This provides a stable foundation for subsequent thickness wear detection and improves the practicality of the device. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1-5 The present invention provides a technical solution: a material wear detection device based on rail transit, including a detection base 1, a detection frame 2 fixed on the top of the detection base 1, a control box 3 fixed inside the top of the detection frame 2; a vertical electric slide rail 4 fixed at the lower right position inside the detection frame 2, and a test clamp 6 installed on the vertical electric slide rail 4 through a first hydraulic rod 5;

[0027] The test caliper 6 is driven to make adaptive vertical and lateral movements by the vertical electric slide rail 4 and the first hydraulic rod 5, so that the test caliper 6 can reach the outer area of ​​the subsequently installed brake pad.

[0028] The top center of the detection seat 1 is equipped with a mounting seat 7 via a motor. The top of the mounting seat 7 is fixed with a mounting column 8. The middle of the mounting column 8 is fitted with a receiving plate 9. A positioning component is installed inside the mounting column 8.

[0029] In one embodiment of the present invention, the positioning assembly includes an electric push rod 101, which is embedded in the cavity inside the mounting column 8. A push head 102 is fixed to the top output end of the electric push rod 101. A crossbar 103 is provided on the outer side of the top of the push head 102. The crossbar 103 is slidably disposed inside the mounting column 8 by means of a spring. A positioning block 104 is fixed to the outer end of the crossbar 103. The positioning block 104 is located on the outer side of the mounting column 8. A guide rod 105 is fixed to the top of the push head 102. The top of the guide rod 105 extends out of the top of the mounting column 8. The outer side of the top of the push head 102 is designed as a slope structure. The outer slope of the top of the push head 102 is parallel and abuts against the bottom slope of the inner end of the crossbar 103. The crossbars 103 are distributed at equal angles inside the mounting column 8. The cross section of the positioning block 104 on the outer side of the crossbar 103 is designed as a right-angled trapezoidal structure. The outer slope of the positioning block 104 is inclined inward.

[0030] The brake pad to be tested is placed on the mounting post 8, positioning it on top of the receiving plate 9. Then, the electric push rod 101 inside the mounting post 8 is activated. The electric push rod 101 pushes the push head 102 upward. The top inclined surface of the push head 102 and the bottom inclined surface of the crossbar 103 push the crossbar 103 to move outward. The crossbar 103 drives the positioning block 104 to move, so that the outer side of the positioning block 104 contacts the inner ring of the brake pad. The outer inclined positioning block 104 supports the brake pad from the inside while applying a downward force to the brake pad, firmly fixing the brake pad to the receiving plate 9.

[0031] In one embodiment of the present invention, the second hydraulic rod 11 is fixed to the bottom of the control box 3. The bottom output end of the second hydraulic rod 11 is connected to the mounting plate 12. The laser measuring instrument 13 is connected to the lower left side of the mounting plate 12 via a horizontal electric slide rail 121. A cleaning and cooling component is provided at the lower right side of the mounting plate 12. An adjustment component is provided on the left side of the cleaning and cooling component. The cleaning and cooling component includes a mounting frame 141, which is laterally slidably disposed in the bottom cavity of the mounting plate 12 via an elastic telescopic rod 142.

[0032] The adjustment assembly includes a vertical rod 151, which slides through the bottom of the mounting plate 12 via a spring. The top of the vertical rod 151 is located in the adjustment groove 152, which is opened in the mounting bracket 141. The bottom of the vertical rod 151 corresponds to the top of the guide rod 105. The right side of the adjustment groove 152 is designed with an inclined structure.

[0033] The second hydraulic rod 11 drives the mounting plate 12 to move down, adjusting the position of the laser measuring instrument 13. When the mounting plate 12 moves down, the vertical rod 151 contacts the guide rod 105, and the force pushes the vertical rod 151 to move upward. The vertical rod 151 abuts against the inclined surface of the adjustment groove 152, pushing the mounting frame 141 to move to the right.

[0034] In one embodiment of the present invention, a blower head 143 is rotatably mounted in the bottom cavity of the mounting bracket 141. A first gear 144 is fixed to the front side of the blower head 143. A second gear 145 meshes with the bottom of the first gear 144. Both the second gear 145 and the first gear 144 are rotatably mounted in the bottom cavity of the mounting bracket 141. A rack 146 meshes with the bottom of the second gear 145. The rack 146 is slidably disposed inside the bottom of the mounting bracket 141 by a spring. The blower head 143 has an overall "L" shaped structure design. The bottom of the blower head 143 blows air outward. The blower head 143 is connected to an external fan through a hose. The left end of the rack 146 abuts against the vertical rod 151. The elastic force of the spring connected to the rack 146 is less than the elastic force of the elastic telescopic rod 142.

[0035] Push the mounting bracket 141 to the right to adjust the position of the blower head 143 according to the brake pad braking area. At the same time, the rack 146 moves away from the vertical rod 151. Under the action of the spring, the rack 146 is pushed to the left. The rack 146 and the second gear 145 drive the first gear 144 to rotate, which in turn drives the blower head 143 to rotate. Adjust the angle of the blower head 143. The motor drives the mounting base 7 and the mounting column 8 to rotate, which drives the brake pad to rotate. The test caliper 6 brakes the brake pad. The transverse electric slide rail 121 drives the laser measuring instrument 13 to move laterally back and forth to detect the thickness of the worn brake pad.

[0036] Working principle: First, the brake pad to be tested is placed on the mounting post 8, so that it is placed on top of the receiving plate 9. Then, the electric push rod 101 inside the mounting post 8 is activated. The electric push rod 101 pushes the push head 102 upward. The top inclined surface of the push head 102 and the bottom inclined surface of the crossbar 103 are structured to push the crossbar 103 to move outward. The crossbar 103 drives the positioning block 104 to move, so that the outer side of the positioning block 104 contacts the inner ring of the brake pad. The outer inclined positioning block 104 supports the brake pad from the inside and can apply a downward force to the brake pad, so that the brake pad is firmly fixed on the receiving plate 9. Then, the test caliper 6 is driven to make adaptive vertical and horizontal movements through the vertical electric slide rail 4 and the first hydraulic rod 5, so that the test caliper 6 reaches the outer area of ​​the brake pad.

[0037] Simultaneously, the second hydraulic rod 11 drives the mounting plate 12 to move downward, adjusting the position of the laser measuring instrument 13. When the mounting plate 12 moves downward, the vertical rod 151 contacts the guide rod 105, and the force pushes the vertical rod 151 to move upward. The vertical rod 151 abuts against the inclined surface of the adjustment groove 152, pushing the mounting bracket 141 to move to the right. The position of the blower head 143 is adjusted according to the brake pad braking area. At the same time, the rack 146 moves away from the vertical rod 151. Under the action of the spring, the rack 146 is pushed to move to the left. The rack 146 and the second gear 145 drive the first gear 144 to rotate, which in turn drives the blower head 143 to rotate. The angle of the blower head 143 is adjusted to facilitate subsequent air blowing and cooling of the subsequent rotating area of ​​the test caliper 6 braking area. Then, the motor drives the mounting base 7 and mounting column 8 to rotate, driving the brake pad to rotate. The test caliper 6 brakes the brake pad. The transverse electric slide rail 121 drives the laser measuring instrument 13 to move laterally back and forth, and the thickness of the worn brake pad is detected to observe whether the wear thickness exceeds the standard.
