Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, and particularly relates to a brake torque lock. Background Art

[0002] Port cranes are located on the shore of port terminals and are the most widely used large-scale mechanical equipment in the process of port loading, unloading and production. Due to the special geographical location of the port, port cranes are extremely vulnerable to sudden strong gusts of wind and slide along the track, resulting in safety accidents such as collisions or rollovers, causing unnecessary losses. Using the trolley brake to provide braking torque for the trolley of the port crane can achieve timely braking and effectively prevent the port crane from slipping caused by sudden strong gusts of wind. The trolley brake of the port crane is generally a normally closed disc brake. When the driver operates the port crane to drive the trolley, the disc brake opens and the trolley moves under the drive of the motor. When the driver stops driving the trolley, the disc brake immediately clamps the brake to ensure that the trolley is always in a windproof state.

[0003] During the safety inspection of the disc brake, it is found that when the disc brake is used for high-frequency braking actions, the torque adjustment nut of the disc brake will loosen under the action of the brake spring, resulting in the phenomenon of running position of the braking torque during the braking process. The decrease of the braking torque will cause insufficient windproof ability of large equipment, and even major problems such as vehicle slipping, collision and overturning. Summary of the Utility Model

[0004] Aiming at the problem that the torque adjustment nut of the disc brake in the prior art is easy to loosen during high-frequency braking actions, the utility model provides a brake torque lock. The position of the brake torque lock is fixed by using the first fixed insertion plate and the second fixed insertion plate, and the mutual locking of the nuts is realized by using the first nut locking hole position and the second nut locking hole position on the locking part, so as to prevent the nuts from loosening and improve the safety and stability of the brake.

[0005] The technical solution of the utility model is as follows:

[0006] A brake torque lock includes a fixed insertion plate, and the fixed insertion plate includes a first fixed insertion plate and a second fixed insertion plate arranged in parallel. The top of the first fixed insertion plate is connected with the top of the second fixed insertion plate through a locking part; the locking part is provided with a first-stage step and a second-stage step, the first-stage step is provided with a first nut locking hole position, and the second-stage step is provided with a second nut locking hole position.

[0007] Further, the brake is an electric disc brake.

[0008] Further, the distance between the inner sides of the first fixed insertion plate and the second fixed insertion plate is equal to the width of the braking spring fixing block of the electric disc brake, so as to ensure that the inner sides of the first fixed insertion plate and the second fixed insertion plate are in close contact with the two opposite sides of the braking spring fixing block.

[0009] Further, the first-level stepped platform is higher than the second-level stepped platform.

[0010] Further, the first nut locking hole position is adapted to the first-level braking torque adjusting nut of the brake. The first nut locking hole position is opened at the bottom of the first-level stepped platform and can penetrate the first-level stepped platform. The first nut locking hole position is used to lock the first-level braking torque nut.

[0011] Further, the second nut locking hole position is adapted to the second-level braking torque adjusting nut of the brake. The second nut locking hole position is opened at the bottom of the second-level stepped platform and can penetrate the second-level stepped platform. The second nut locking hole position is used to lock the second-level braking torque nut.

[0012] The beneficial effects of the present utility model are as follows:

[0013] A brake torque lock provided by the present utility model uses the first fixed insertion plate and the second fixed insertion plate arranged in parallel to provide fixed support for the locking part, preventing the locking part from shifting; a first-level stepped platform and a second-level stepped platform are provided on the locking part, a first nut locking hole position is opened on the first-level stepped platform, and a second nut locking hole position is opened on the second-level stepped platform, realizing the simultaneous interlocking of two nuts, preventing the change of the braking torque of the brake caused by the loosening of the nuts, and improving the safety and stability of the brake.

[0019] Embodiment 1

[0020] A brake torque lock includes a fixed insertion plate, as Figure 1 and Figure 2 shown. The fixed insertion plate includes a first fixed insertion plate 1 and a second fixed insertion plate 2. The first fixed insertion plate 1 and the second fixed insertion plate 2 are arranged in parallel. The distance between the inner sides of the first fixed insertion plate 1 and the second fixed insertion plate 2 is equal to the width of the brake spring fixing block of the brake. The first fixed insertion plate 1 is connected to the second fixed insertion plate 2 through a locking portion. The locking portion is welded and fixed on the upper surfaces of the first fixed insertion plate 1 and the second fixed insertion plate 2. The locking portion is sequentially provided with a first-stage step 3 and a second-stage step 4 along the length direction. The upper end surface of the first-stage step 3 is higher than the upper end surface of the second-stage step 4. A first nut locking hole position 5 penetrating the first-stage step 3 is opened at the middle position of the first-stage step 3, and a second nut locking hole position 6 penetrating the second-stage step 4 is opened at the middle position of the second-stage step 4. The cross-sections of the first nut locking hole position 5 and the second nut locking hole position 6 are both hexagonal. The first nut locking hole position 5 is adapted to the first-stage braking torque adjusting nut of the brake, and the second nut locking hole position 6 is adapted to the second-stage braking torque adjusting nut of the brake. Among them, the model of the brake is YP11-Ed220-50-355*20.

[0021] Usage method: First, calibrate the primary braking torque adjusting nut and the secondary braking torque adjusting nut installed above the brake spring fixing block, and adjust them to appropriate positions. Then, insert the first fixing plug and the second fixing plug of the brake torque lock from top to bottom into the gaps on both sides of the brake spring fixing block, so that the inner sides of the first fixing plug and the second fixing plug are in close contact with the two opposite sides of the brake spring fixing block exposed in the gaps. When the bottom surface of the locking part of the brake torque lock contacts the upper end surface of the brake spring fixing block, the primary braking torque adjusting nut is nested in the first nut locking hole position, and at the same time, the secondary braking torque adjusting nut is nested in the second nut locking hole position. The thicknesses of both the primary step and the secondary step do not exceed the heights of their corresponding braking torque adjusting nuts. The present utility model realizes the fixation of the locking part by setting the first fixing plug and the second fixing plug, and realizes the simultaneous locking of the primary braking torque adjusting nut and the secondary braking torque adjusting nut through the first nut locking hole position and the second nut locking hole position on the locking part.
