Technical Field

[0001] The utility model relates to the technical field of trolley brake devices, in particular to a tire half-component trolley brake device. Background Art

[0002] The trolley is a tool used to load tire semi-component materials. During the transportation process, it is necessary to ensure that the material reel and the pad cloth reel do not rotate to prevent the material and the pad cloth from falling to the ground. The trolley brake device is a structure that locks the two reels to realize the control of the trolley operation.

[0003] The existing related technologies often have the following defects: the existing trolley brake devices are mainly friction disc type and latch type. The main disadvantage of the friction disc type is that it is difficult to adjust the clamping force of the brake pad. The main disadvantage of the latch type is that the latch is easy to fall off. Two reels require two latches. Employees sometimes forget to pull out one of the latches, resulting in an equipment overload alarm when the equipment is unloaded.

[0004] Therefore, the utility model provides a tire half-component trolley brake device. Utility Model Content

[0015] The effect achieved by the above components is that the pressure rod drives the two pull ropes to pull down.

[0016] Preferably, two connecting blocks are fixedly connected to the lower side of the sliding frame, and a spring is fixedly connected to one side of the connecting block and the connecting frame close to each other.

[0017] The effect achieved by the above components is that when the pressure rod is loosened, the sliding frame will be reset by the elastic force of the spring between the connecting block and the connecting frame.

[0027] Reference Figure 1 As shown, the utility model provides a technical solution: a tire half-component trolley brake device, comprising a mounting plate 1, wherein two engaging discs 4 are rotatably connected inside the mounting plate 1.

[0028] The following is a detailed description of its overall specific settings and functions.

[0029] Reference Figure 1 and Figure 2As shown, in this embodiment: two mounting blocks 3 are fixedly mounted on the surface of the mounting plate 1, and the insides of the two mounting blocks 3 are slidably connected with sliding pins 7, and the lower sides of the two sliding pins 7 are fixedly mounted with brake rods 2, and both sides of the brake rods 2 are provided with tooth surfaces, and the tooth surfaces on the brake rods 2 mesh with the tooth surfaces on the meshing plate 4, and the upper ends of the two sliding pins 7 are fixedly mounted with connecting plates 8, and the surface of the mounting plate 1 is fixedly mounted with positioning blocks 10, and the inside of the positioning blocks 10 is slidably connected with limit pins 9, and the limit pins 9 are rotatably connected with the inside of the connecting plate 8. When the brake rod 2 is lifted, the meshing is separated, and the reel can rotate freely. When the brake rod 2 falls, it meshes with the gear to lock the reel. After the reel is locked, the reel does not rotate during the transportation process, and the material and the pad cloth are tightly wrapped around the reel, and the material does not accumulate or stick. The gears are meshed, the locking is firm, and the brake is convenient to lock and unlock, which improves the performance of the tire half-component trolley brake device to a certain extent. The side wall of the positioning block 10 is provided with a limit groove 12, and the side wall of the limit pin 9 is fixedly connected with a control rod 11, and the control rod 11 is located inside the limit groove 12. The control rod 11 is slid inside the limit groove 12, and the control rod 11 is moved to the lowest side position of the limit groove 12. At this time, the side of the brake lever 2 with the tooth surface can be controlled to be stuck on the surface of the two meshing discs 4, so as to realize the simultaneous locking of the two meshing discs 4. The control rod 11 is lifted and moved to the topmost position of the limit groove 12, so as to realize the lifting of the brake lever 2, which is convenient for the normal operation of the meshing disc 4.

[0030] Reference Figure 1-Figure 4 As shown, specifically, two connecting frames 13 are fixedly installed on the surface of the mounting plate 1, and a sliding frame 14 is slidably connected inside the connecting frame 13. A pressing plate 15 is fixedly installed on the end side of the sliding frame 14, and an anti-skid pad 16 is glued on the surface of the pressing plate 15. The sliding frame 14 will drive the anti-skid pad 16 on the pressing plate 15 to stick to the surface of the meshing disk 4, thereby increasing the resistance of the meshing disk 4 during the rotation process and facilitating the deceleration of the meshing disk 4. A pulley 19 is rotatably connected to the inner side of the connecting frame 13, and a pull rope 6 is fixedly connected to the inner side of the sliding frame 14, and the pull rope 6 is located on the side wall of the pulley 19. The pull rope 6 slides on the surface of the pulley 19 to change the pulling direction of the pull rope 6.

[0031] The lower ends of the two pull ropes 6 are fixedly connected with a pressure rod 5. The pressure rod 5 will drive the two pull ropes 6 to pull down. Two connecting blocks 17 are fixedly connected to the lower side of the slide frame 14, and a spring 18 is fixedly connected to the side where the connecting block 17 and the connecting frame 13 are close to each other. When the pressure rod 5 is released, the slide frame 14 will be reset by the elastic force of the spring 18 between the connecting block 17 and the connecting frame 13. Two rectangular bars 20 are fixedly connected to the surface of the mounting plate 1, and a limiting frame 21 is slidably connected to the inner side of the rectangular bar 20, and the lower end of the limiting frame 21 is fixedly connected to the pressure rod 5. The limiting frame 21 on the pressure rod 5 slides inside the rectangular bar 20 to limit the moving direction of the pressure rod 5.

[0032] Working principle: when it is necessary to lock the engaging disk 4, the operating rod 11 can be slid inside the limiting groove 12 to move the operating rod 11 to the lowest side position of the limiting groove 12. At this time, the side of the brake rod 2 with the tooth surface can be controlled to be stuck in the surface of the two engaging disks 4, thereby realizing the simultaneous locking of the two engaging disks 4, lifting the operating rod 11 and moving the operating rod 11 to the topmost position of the limiting groove 12 to realize the lifting of the brake rod 2, which is convenient for the normal operation of the engaging disk 4. Before the engaging disk 4 needs to be braked, the pressure rod 5 can be stepped on, and the limiting frame 21 on the pressure rod 5 slides inside the rectangular bar 20 to limit the moving direction of the pressure rod 5. The pressure rod 5 will drive the two pull ropes 6 to pull down, and the pull rope 6 slides on the surface of the pulley 19 to change the pulling direction of the pull rope 6. At this time, the movement of the sliding frame 14 can be realized, and the sliding frame 14 will drive the anti-skid pad 16 on the pressure plate 15 to stick to the surface of the engaging disk 4. The outer edge of the meshing disk 4 connecting the trolley and the equipment is designed to be gear-type, and the two ends of the brake rod 2 are designed to be toothed and meshed with the gear of the meshing disk 4. When the brake rod 2 is lifted, the meshing is separated and the spool can rotate freely. When the brake rod 2 falls, it meshes with the gear to lock the spool. After the spool is locked, the spool does not rotate during transportation, and the material and the pad cloth are tightly wrapped around the spool. The material does not accumulate or stick. The gears are meshed and locked firmly. The brake is locked and unlocked conveniently, which improves the performance of the brake device of the tire half-component trolley to a certain extent.
