Description

Safety brake slider stop device

Technical Field

The utility model relates to a safety brake's mechanism, specifically speaking are safety brake slider stop device.

Background

A disk locking device used as a safety brake is characterized in that a wedge-shaped groove is formed in a base, two sliding blocks with opposite braking surfaces are arranged in the wedge-shaped groove, each sliding block is of a wedge-shaped block structure, the braking surfaces of the sliding blocks are planes, the rear side of each sliding block is a slope surface, and friction plates are attached to the braking surfaces of the sliding blocks. The two oppositely arranged sliding blocks are pushed by the braking electromagnet in the wedge-shaped groove of the base to clamp the brake disc with large torque arranged between two sides, the brake disc drives the sliding blocks to move towards the narrow opening end of the wedge-shaped groove through friction force, and the brake disc is clamped under the action of the wedge-shaped groove, so that the emergency braking purpose is realized.

However, the disc locking device has certain disadvantages, such as that after the brake disc is clamped tightly by implementing emergency braking, the wedge-shaped groove of the base also clamps the sliding block tightly, so that the sliding block is difficult to withdraw, great inconvenience is brought to field unlocking operation of a maintenance worker for the safety brake, the maintenance time of the safety brake is prolonged, and the normal use of a braked device is delayed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a safety brake slider stop device to solve the inconvenient problem of current lock dish ware unblock after the braking.

The utility model discloses a realize like this: a safety brake slide stop device comprising:

the support frame is arranged on the outer end face beside the narrow end of the wedge-shaped groove of the brake base, is used for fixedly connecting the stop block and provides an accommodating space for the extension section of the sliding block of the brake extending out of the narrow end of the wedge-shaped groove during braking; and

and the stop block is arranged on the support frame and used for stopping the extending position of the sliding block of the brake, which extends out of the narrow end of the wedge-shaped groove, for limiting in a blocking manner.

The utility model discloses still include:

the extending end of the screw hole penetrating through the inner end surface of the stop block is an adjustable limiting end of the stopping slide block.

The utility model discloses utilize the dog of horizontal in the stopper base wedge groove slot end outside to be the basis, the utilization relies on the jackscrew that reaches the dead point before the adjusting bolt on the dog is as the restriction slider, carry out appropriate spacing by the slider that base wedge groove front end mouth explored forward during to the braking from this, make the slider both can satisfy the effect purpose of pressing from both sides dead brake disc, but also can not form with the notch in base wedge groove and press from both sides the dead state, both can solve the problem that the slider withdraws from the difficulty effectively from this, make safety brake's on-the-spot unblock operation very convenient, safety brake's unblock maintenance time has both been shortened, accelerated again by braking equipment's normal use, user's user needs have been satisfied.

Detailed Description

As shown in fig. 1, a wedge-shaped groove is formed in a base 7 of the brake, two wedge-shaped sliding blocks 8 are arranged in the groove, a friction plate 9 is attached to the braking surface of each sliding block, and a brake disc 10 is clamped between the two sliding blocks 8. The utility model comprises a support frame 1 and a stop block 2. The support frame 1 is arranged on the outer end faces of two sides of the narrow end of the wedge-shaped groove of the base 7 and is used for being fixedly connected with the stop block 2 and providing accommodating space for the sliding block 8 to extend out of the extending section of the narrow end of the wedge-shaped groove during braking. The stop block 2 is arranged on the support frame 1 and used for stopping and limiting the extending position of the slide block 8 extending out of the narrow end of the wedge-shaped groove during braking so as to prevent the slide block from being stuck in the wedge-shaped groove.

The support frame 1 can be fixed on the base 7 by welding (fig. 3) or screw connection (fig. 1). The stop block 8 and the support frame 1 can be of a split structure, and the two are connected together in a welding (fig. 3 and 4) or screw connection (fig. 1 and 2) mode. The stop 8 may also be formed integrally with the support 1 and then fixed to the base 7.

As shown in fig. 1 and 2, the stopper 2 is of an integral structure or a split integral structure, and a notch (fig. 5) for avoiding the brake disc 10 is formed at a central position of the upper edge of the stopper 2.

As shown in fig. 3 and 4, the block 2 is a split structure composed of two symmetrical split bodies, and each split body of the block 2 is connected with a support frame 1, so that a gap avoiding the brake disc 10 is formed between the two split bodies of the block 2.

As shown in fig. 2 and 4, the utility model can also be provided with a screw hole on the stop block 2, and the screw hole points to the end surface of the slide block 8. The adjusting bolt 3 is threaded in the threaded hole. The adjusting bolt 3 is in threaded connection with the stop block 2 to form a jackscrew, and the sliding block 8 which forwards extends out of the wedge-shaped groove of the base when the brake is braked is limited. The front and back position adjustment of the limiting end of the sliding block can be realized by adjusting the position of the adjusting bolt 3, so that the front extension amount of the sliding block 8 is adjusted, the adjusting bolt 3 is in the best position, the sliding block 8 can achieve the purpose of clamping the brake disc 10, and the sliding block and the notch of the wedge-shaped groove of the base cannot form a clamping state, so that the safety brake forms a flexible braking effect.
