Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 4 As shown, the utility model provides a pneumatic brake device for starting and stopping a wire rope winch, which includes a frame 2 arranged on both sides of a winch 1, two frames 2 are provided with movably connected distance adjusting columns 3, and the opposite surfaces of the two distance adjusting columns 3 are provided with brake pads 4 for braking the winch 1. The fitting surface of the brake pads 4 and the winch 1 is in an arc shape, so that the winch 1 can be braked.

[0025] A solenoid valve is installed inside the frame 2, and a cylinder 18 is provided on the top of the frame 2 on the side of the winch 1 away from the brake pad 4. A pull rod for controlling the movement of two brake pads is connected to the telescopic rod of the cylinder 18, and the solenoid valve controls the movement of the cylinder 18 to realize the start and stop of the winch 1 brake.

[0026] It should be explained that the pull rods are respectively connected to the two brake pads 4. Under the control of the solenoid valve, the movement stroke of the cylinder 18 can be realized, thereby driving the position of the pull rod to change, realizing the position movement of the brake pads 4, and realizing the start and stop of the winch 1.

[0027] A fixedly connected travel rack 5 is symmetrically provided at the bottom of the distance adjusting column 3, and a linkage gear 6 is symmetrically provided inside the frame body 2. The linkage gear 6 cooperates with the travel rack 5. A main shaft 7 that passes through and is connected to the frame body 2 is provided on the two linkage gears 6. A motor 8 with an external power supply is provided on one side of the frame body 2, and the output shaft of the motor 8 is connected to the main shaft 7.

[0028] It needs to be explained that, under the drive of the motor 8, the linkage gear 6 is driven to move the rack, thereby changing the position of the distance adjustment column 3, so that the distance between the two brake pads 4 can be adjusted, and the flexibility of the brake pads 4 can be improved. When replacing the winch 1 of different sizes, there is no need to replace the entire equipment, which is more convenient and flexible.

[0029] Preferably, the frame 2 is welded by two vertical straight plates 2-1 and vertically spaced reinforcement plates 2-2, the reinforcement plate 2-2 is arranged between the two straight plates 2-1, and the bottom of the frame 2 is fixed to the ground. The straight plates 2-1 and the reinforcement plates 2-2 are made of steel plates to ensure a certain strength, thereby avoiding tilting.

[0030] Preferably, a fixedly connected limit plate 9 is provided on the side of the frame body 2 away from the winch 1 , a penetrating guide hole 10 is provided inside the limit plate 9 , and the distance adjustment column 3 passes through the guide hole 10 and is movably connected to the limit plate 9 .

[0031] It needs to be explained that the vertical section of the distance adjusting column 3 cooperates with the guide hole 10 so that the distance adjusting column 3 can be kept unchanged during movement, and the limit plate 9 is fixedly connected to the frame 2 to provide a certain supporting force for the distance adjusting column 3.

[0032] Preferably, the brake pad 4 adopts a pneumatic brake mode, and the solenoid valve and the start brake are electrically connected.

[0033] It needs to be explained that by setting the winch 1 in the winch machine to also serve as a brake disc, using a pneumatic brake, and using an electromagnetic valve to control the air pressure to meet the requirements of the winch 1 brake start and stop operation, it is safer, more reliable and more applicable when facing large equipment inertia.

[0034] Preferably, an anti-skid sheet 11 is provided on one side of the two brake pads 4 close to the winch 1 . The anti-skid sheet 11 can further increase the friction force, thereby achieving normal braking of the winch 1 .

[0035] Preferably, a mounting block 12 is disposed on the top of the two frames 2 , and a threaded rod 13 and a matching rod 14 are respectively disposed on opposite surfaces of the two mounting blocks 12 , and the threaded rod 13 and the matching rod 14 are movably connected.

[0036] Preferably, the threaded rod 13 extends into the interior of the matching rod 14 , and a locking ring 15 is provided at the exterior where the matching rod 14 and the threaded rod 13 intersect to fix the two to each other.

[0037] It needs to be explained that the threaded rod 13 can be movably inserted into the interior of the matching rod 14. When the distance between the two frames 2 is adjusted and installed, the inner wall of the locking ring has an inner screw that matches the outer screw on the threaded rod 13. It can be locked when it is pressed against one end of the matching rod 14, keeping the threaded rod 13 and the matching position stationary, thereby maintaining the relative distance between the two frames 2, so that during long-term work, the brake pad 4 can brake the winch 1 at the same time when braking.

[0038] Preferably, a vertical limiting cable 16 is provided on the other side of the frame 2 where the cylinder 18 is installed. The top of the limiting cable 16 is fixedly connected to the mounting block 12 , and the other end passes through a cable fixture 17 fixed on the top of the frame 2 .

[0039] It needs to be explained that one end of the limiting cable 16 is fixedly connected to the mounting block 12, and the other end of the limiting cable 16 is fixed by a cable fixture 17. The cable fixture 17 can adjust the length of the limiting cable 16. After the frame 2 is installed, the cable is straightened by the cable fixture 17, so that the frame 2 can be stabilized and can maintain a relative balance with the cylinder 18 on the other side, thereby maintaining the stability of the frame 2 during long-term work.

[0040] Detailed usage and effects of the above embodiments:

[0041] The pneumatic brake device is installed on the frame 2 on the winch machine, so that the winch 1 can also serve as a brake disc. Under normal conditions, the solenoid valve is energized and the brake pad 4 is not engaged. When the winch 1 needs to be stopped, the solenoid valve is powered off. At this time, the air source is controlled to pass, and the cylinder 18 is connected to the two brake pads 4 through a pull rod, thereby controlling the movement of the brake pad 4 and contacting the winch 1 to stop the winch 1.

[0042] When faced with winches 1 of different diameters, we do not need to disassemble the entire device or replace different brake pads 4. We only need to move the entire device to the next position for installation, and then start the motor 8. The motor 8 will drive the linkage gear 6 to rotate through the main shaft 7. The linkage gear 6 cooperates with the travel gear to drive the linkage gear 6 to move. The brake pad 4 is fixedly connected to the distance adjusting column 3, so that the distance between the two distance adjusting columns 3 can be flexibly adjusted to adapt to winches 1 of different diameters.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
