Detailed Description of the Preferred Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a mine car caliper brake inspection mechanism, including a support platform 1 and a controller. The controller is a PLC logic controller, a PCB control board or a host. Support legs are provided at the bottom edge of the support platform 1, and a control cabinet 21 fixed to the support legs is provided below the support platform 1. A hydraulic control station connected to the controller is provided inside the control cabinet 21, and the controller is arranged inside the control cabinet 21;

[0023] The controller is connected to a display device. As Figure 1 shown, the display device includes a display screen bracket 14 provided at one side edge of the support platform 1. An operation screen 12 is installed on the top of the display screen bracket 14, and the operation screen 12 is connected to the controller.

[0024] A second support 9 is provided at the top of the support platform 1. A second L-shaped frame 15 is provided on one side of the second support 9. Both the second L-shaped frame 15 and the bottom of the second support 9 are connected to the support platform 1. As Figure 1 shown, a bearing seat 16 is provided at the top of the second L-shaped frame 15. A drive shaft 23 is rotatably provided in the bearing seat 16, and the two are connected by a bearing. One end of the drive shaft 23 is connected to a torque sensor 13. The torque sensor 13 is connected to a controller, and the torque sensor 13 is installed on the support table 22. The support table 22 is located on the side of the second L-shaped frame 15 and is connected to the second L-shaped frame 15. The other end of the torque sensor 13 is connected to a drive mechanism. As Figure 2 shown, the drive mechanism includes a gearbox 11. The gearbox 11 is connected to the end of the torque sensor 13. The other end of the gearbox 11 is connected to a drive motor 10. Both the drive motor 10 and the gearbox 11 are installed on the support platform 1. The drive motor 10 is connected to the controller. During use, the drive motor drives the torque sensor 13 and the drive shaft 23 to rotate after deceleration through the gearbox.

[0025] One end of the drive shaft 23 away from the drive mechanism is a load end, that is, a caliper brake is installed at the end. As Figure 1 shown, specifically, a brake disc 17 is installed at one end of the drive shaft 23 away from the drive mechanism. Among them, one side of the brake disc 17 is placed inside the second caliper 18. The second caliper 18 is connected to the second support 9 through a first frame. As Figure 4 shown, the specific structure of the first frame includes a second mounting frame 26 provided on the side of the second support 9 close to the brake disc 17. A second caliper bracket 19 matching the second caliper 18 is installed at the end of the second mounting frame 26. The second caliper 18 is installed in the second caliper bracket 19, that is, the second caliper 18 can be fixed and disassembled by being fastened in the second caliper bracket 19 with bolts. The second caliper 18 is connected to the hydraulic control station through a pipeline. The controller controls the hydraulic control station to supply oil into the second caliper 18, so that the second caliper 18 clamps the brake disc 17;

[0026] The specific operation process is as follows: Install the second caliper 18 in the second caliper bracket 19. At the beginning, the second caliper 18 is open. Place the edge of the brake disc 17 inside the second caliper 18. Then connect the pipeline of the second caliper 18 to the hydraulic control station. The hydraulic control station supplies oil into the second caliper 18 to establish oil pressure, so as to simulate the vehicle oil pump supplying oil into the caliper brake. Therefore, as the oil pressure increases, the second caliper 18 will tightly clamp on the brake disc 17 to simulate the braking process;

[0027] Before the second caliper 18 is clamped, start the drive motor 10 to drive the drive shaft 23 to rotate, so as to simulate the process of wheel rotation. When the force of the second caliper 18 gradually tightens, the brake disc 17 can be braked, and the output torque of the drive motor 10 can be monitored in real time by the torque sensor 13. It should be noted that after the drive motor 10 is decelerated by the gearbox 11, its output torque is greater than the maximum braking pressure value of the second caliper 18, so as to observe the working condition of the second caliper 18 under the extreme braking state.

[0028] However, in the above process, only the output torque of the drive motor when the second caliper 18 is braking can be measured, so as to obtain the torque condition of the wheel axle. However, the pressure of the second caliper 18 cannot be measured. Therefore, a device capable of monitoring the clamping force of the second caliper 18 is needed. The device includes a first bracket 5 arranged on the top of the support platform 1. One side of the first bracket 5 is connected to the first L-shaped frame 8. Both the first L-shaped frame 8 and the first bracket 5 are arranged on the support platform 1. As Figure 1 shown, a fixing seat 7 is installed on the top of the first L-shaped frame 8. A support shaft 20 is horizontally installed in the fixing seat 7. A clamping disc 2 is arranged at the end of the support shaft 20. One side of the clamping disc 2 is placed inside the first caliper 3. The first caliper 3 is connected to the first bracket 5 through a second frame body. As Figure 5 shown, the second frame body includes a first mounting frame 25 arranged on the side of the first bracket 5 close to the clamping disc 2. A first caliper bracket 4 matching the first caliper 3 is arranged at the end of the first mounting frame 25. The first caliper 3 is arranged inside the first caliper bracket 4. The first caliper 3 and the second caliper 18 are of the same specification;

[0029] A pressure sensor is arranged on the surface of the clamping disc 2 located inside the first caliper 3 (as Figure 5 indicated by the arrow A). The pressure sensor is connected to the controller. The first caliper 3 is connected to the hydraulic control station through a pipeline. It should be noted that the first caliper 3 and the second caliper 18 are simultaneously connected to the hydraulic control station through pipelines, that is, the pipelines on the first caliper 3 and the second caliper 18 are interconnected. The hydraulic control station simultaneously delivers hydraulic oil into the first caliper 3 and the second caliper 18. Because the oil pressure coming out of the hydraulic control station is constant, and because the pipelines of the first caliper 3 and the second caliper 18 are interconnected, it can be considered that the first caliper 3 and the second caliper 18 are connected to the same pipeline. Therefore, the oil pressure at any point in the same pipeline is the same. Therefore, the clamping forces of the first caliper 3 and the second caliper 18 are the same. When in use, the pressure of the first caliper 3 on the clamping disc 2 is the pressure of the second caliper 18 on the brake disc 17.

[0030] It should be noted that setting the calipers to two, namely the first caliper 3 and the second caliper 18, also has the following advantages. That is, the positions of the first caliper 3 and the second caliper 18 can be swapped, and the above operations can be repeated. In this way, the braking effects of the two calipers can be monitored, and the braking capabilities of the two calipers can be detected accordingly.

[0031] Furthermore, a first annular seat 6 is coaxially provided at one end of the support shaft 20 close to the clamping disc 2. The clamping disc 2 is disposed through the first annular seat 6, and the clamping disc 2 and the first annular seat 6 are fastened by bolts, which facilitates the disassembly and installation of the clamping disc 2.

[0032] Even further, a second annular seat 24 is coaxially provided at one end of the drive shaft 23 close to the brake disc 17. The brake disc 17 and the second annular seat 24 are fastened by bolts, which facilitates the disassembly and installation of the brake disc 17 and is convenient for replacing a new brake disc.

[0033] Based on the above embodiments, it can be further optimized that pressure monitors are respectively installed on the pipelines of the first caliper 3 and the second caliper 18, so that the oil pressure condition can be monitored.

[0034] Based on the above embodiments, it can be further optimized that an exhaust fan and a ventilation louver are installed on the side surface of the control cabinet 21.
