After the brake unit is overhauled, the inspection department shall supervise and accept the quality of the brake unit. The inspector shall conduct random inspections according to regulations and conduct test bench inspections according to the "XFD Tread Brake Unit Maintenance Test Specifications". After passing the inspection, the maintenance record, test report and certificate shall be filled in before the finished product can be put into storage and loaded for use.

[0003] Since the brake unit has many disassembly and maintenance surfaces during disassembly and maintenance, and the brake unit is heavy, at least two people are required to cooperate to turn over the brake unit on the workbench. This is not only laborious, but also in the process of turning over the brake unit, the brake unit can easily cause crushing injuries to the fingers of the workers, seriously affecting the efficiency of disassembly and maintenance of the brake unit. Summary of the invention

[0004] In view of this, the present invention provides a brake unit flipping device and method to solve the problem in the prior art that, due to the large number of disassembly and maintenance surfaces of the brake unit when it is disassembled and repaired, and the heavy weight of the brake unit, at least two people are required to cooperate to flip the brake unit on the workbench, which is not only laborious but also in the process of flipping the brake unit, the brake unit can easily cause crushing injuries to the fingers of the staff, seriously affecting the work efficiency of disassembling and repairing the brake unit.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A braking unit flipping device comprises a base, a frame is vertically arranged on the top of the base, a mounting seat is slidably connected inside the frame, a motor is provided on the mounting seat, a rotating shaft is fixedly connected to the output end of the motor, a first placement seat is fixedly connected to the rotating shaft, the first placement seat is provided with a plurality of first fixing holes corresponding to the through holes on the braking unit; and a lifting device for lifting the mounting seat is also included.

[0007] In this technical solution, it should be noted that when the brake unit needs to be inspected and repaired, the first placement seat is first lowered to a lower position by the lifting device, so that the work team can move the brake unit to the first placement seat more labor-saving. After the first placement seat is lowered, the staff places the brake unit on the first placement seat, and aligns the first fixing hole on the first placement seat with the through hole on the brake unit, and then passes the bolt through the first fixing hole and the through hole, and screws two nuts at both ends of the bolt to fix the first placement seat and the brake unit. After the brake unit is fixed, the staff raises the first placement seat to a height that is convenient for the staff to inspect and repair by the lifting device, and then the brake unit can be inspected and repaired. When the brake unit needs to be flipped, the motor is started, and the motor drives the first placement seat to rotate 180 degrees. At this time, the brake unit rotates 180 degrees, and the flipping of the brake unit is completed. In summary, in the present invention, the first placement seat can be driven to rise or fall by the provided lifting device. When the first placement seat is lowered to the position for briefing, the staff can place the brake unit on the first placement seat with less effort. When the first placement seat is raised to a certain height, the staff can inspect the brake unit more easily without squatting to inspect the brake unit. Secondly, in the present invention, the brake unit on the first placement seat can be automatically flipped by the provided motor, and there is no need for multiple people to cooperate in flipping.

[0008] Preferably, the lifting device includes a screw, the upper and lower ends of which are rotatably connected to the upper and lower ends of the frame respectively, the frame is provided with a driving machine for driving the screw to rotate, and the mounting seat is threadedly connected to the screw.

[0009] In this technical solution, it should be noted that the lifting device specifically includes a lead screw and a driving machine, and the lead screw is driven to rotate by the driving machine to drive the mounting seat to rise or fall.

[0010] Preferably, a second placement seat is further provided on the base, the second placement seat is located below the first placement seat, and the second placement seat is provided with a plurality of second fixing holes.

[0011] In this technical solution, it should be noted that after the brake unit on the first placement seat is flipped 180 degrees, the side of the brake unit in contact with the first placement seat is still blocked by the first placement seat. At this time, the staff can only remove the brake unit from the first placement seat to inspect the blocked surface. However, when removing the brake unit, the staff is required to hold up the brake unit to prevent it from falling, which increases the work intensity of the staff. Based on this, the present invention is provided with a second placement seat. After the brake unit is flipped 180 degrees, the bottom of the brake unit is in contact with the second placement seat or there is only a small width gap. At this time, the staff only needs to remove the bolts on the first placement seat, and the brake unit can automatically fall on the second placement seat without manually holding up the brake unit.

[0012] Preferably, the base is provided with a slide rail, the slide rail is arranged along the width direction of the base, and the second placement seat is slidably connected to the slide rail. The rotating shaft is provided with a connecting rope, and the end of the connecting rope away from the rotating shaft is connected to the slide seat. The base is provided with a guide plate, the guide plate is provided with a through hole, and the end of the connecting rope away from the rotating shaft passes through the through hole and is connected to the bottom of the groove. The first placement seat includes a horizontal plate and a vertical plate, the horizontal plate and the vertical plate are vertically arranged, the first fixing hole is provided on the horizontal plate, and the end of the horizontal plate is detachably connected to the vertical plate.

[0013] In this technical solution, it should be noted that in order to facilitate the staff to carry the brake unit to the first placement seat, the first placement seat needs to be lowered to a certain position. However, during the lowering process of the first placement seat, the second placement seat located below the first placement seat will form a blockage for the first placement seat, so that the first placement seat cannot be lowered to the lowest position. Based on this, the present invention arranges a connecting rope and a guide rail so that the position of the second placement seat can be automatically adjusted. The specific principle is as follows: in the initial state, the first placement seat is aligned with the second placement seat up and down, and the second placement seat is pushed inward so that the second placement seat and the first placement seat are staggered with each other. At this time, the connecting rope is in a straight state; start the driving machine, the driving machine drives the lead screw to rotate forward, so that the mounting seat threadedly connected to the lead screw descends, and the mounting seat drives the first placement seat to descend to the initial position of the second placement seat, at this time The connecting rope is in a relaxed state; place the brake unit on the first placement seat, and align the first fixing hole on the first placement seat with the through hole on the brake unit, and then through The bolt passes through the first fixing hole and the through hole, and two nuts are screwed into the two ends of the bolt to fix the first placement seat and the brake unit; start the driving machine, the driving machine drives the lead screw to reverse, so that the mounting seat threaded with the lead screw rises to the initial position, and the staff can inspect the brake unit, and the connecting rope is restored to a straight state at this time; when the brake unit needs to be flipped, start the motor, the motor drives the rotating shaft to rotate, and then the first placement seat rotates. During the rotation of the rotating shaft, the connecting rope is wrapped around the rotating shaft, and then the second placement seat below is pulled to move. When the first placement seat rotates 180 degrees, the second placement seat is just moved to the bottom of the first placement seat, and the second placement seat and the brake unit are in contact or separated by a certain gap. At this time, the bolts and nuts on the first placement seat are released, and the flipped brake unit is placed on the second placement seat and fixed through the second fixing hole; remove the horizontal plate from the vertical plate. At this time, there is no interference above the brake unit located at the top of the second placement seat, and the brake unit can be inspected.

[0014] Preferably, wheels are provided at the bottom of the base.

[0015] In this technical solution, it should be noted that the wheels facilitate the movement of the tooling, and the wheels have built-in brake structures. The brake structures are prior art and will not be described in detail here.

[0016] A brake unit flipping method, comprising:

[0017] Step 1: In the initial state, the first placement seat is aligned with the second placement seat up and down, and the second placement seat is pushed inward so that the second placement seat and the first placement seat are staggered with each other. At this time, the connecting rope is in a straight state;

[0018] Step 2: Start the driving machine, which drives the lead screw to rotate forward, so that the mounting seat connected to the lead screw thread descends, and the mounting seat drives the first placement seat to descend to the initial position of the second placement seat. At this time, the connecting rope is in a relaxed state;

[0019] Step 3: Place the brake unit on the first placement seat, and align the first fixing hole on the first placement seat with the through hole on the brake unit, then pass a bolt through the first fixing hole and the through hole, and screw two nuts into both ends of the bolt to fix the first placement seat and the brake unit;

[0020] Step 4: Start the driver, which drives the lead screw to reverse, so that the mounting seat connected to the lead screw thread rises to the initial position, and the staff can inspect the brake unit. At this time, the connecting rope returns to the straight state;

[0021] Step 5: When the brake unit needs to be flipped, the motor is started, and the motor drives the rotating shaft to rotate, thereby rotating the first placement seat. During the rotation of the rotating shaft, the connecting rope is wound around the rotating shaft, thereby pulling the second placement seat below to move. After the first placement seat rotates 180 degrees, the second placement seat is moved just below the first placement seat, and the second placement seat and the brake unit are in contact or separated by a certain gap. At this time, the bolts and nuts on the first placement seat are released, and the flipped brake unit is placed on the second placement seat, and fixed through the second fixing hole;

[0022] Step 6: Remove the horizontal plate from the vertical plate. Now there is no interference above the brake unit located on the top of the second placement seat, and the brake unit can be inspected and repaired.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, the lifting device can drive the first placement seat to rise or fall. When the first placement seat is lowered to the position for briefing, the staff can place the brake unit on the first placement seat with relatively less effort. When the first placement seat rises to a certain height, the staff can inspect the brake unit relatively easily without squatting to inspect the brake unit. Secondly, in the present invention, the motor can automatically flip the brake unit on the first placement seat without the cooperation of multiple personnel to flip it.

[0025] 2. In the present invention, a second placement seat is provided. When the brake unit is turned over 180 degrees, the bottom of the brake unit is in contact with the second placement seat or there is only a small gap between them. At this time, the staff only needs to remove the bolts on the first placement seat, and the brake unit can automatically fall on the second placement seat without manually lifting the brake unit;

[0026] 3. In the present invention, it should be noted that in order to facilitate the staff to carry the brake unit to the first placement seat, the first placement seat needs to be lowered to a certain position. However, during the descending process of the first placement seat, the second placement seat located below the first placement seat will block the first placement seat, so that the first placement seat cannot be lowered to the lowest position. Based on this, the present invention arranges a connecting rope and a guide rail so that the position of the second placement seat can be automatically adjusted, that is, during the rotation of the first placement seat, the connecting rope will be driven to wrap around the rotating shaft, and then the second placement seat will be automatically pulled below the first placement seat.
