Embodiment 1

[0035] Such as figure 1 , figure 2 , image 3As shown, the frame 1 is a three-dimensional frame structure in the shape of a square column, and upper and lower opposite slit openings are arranged on the top surface and the bottom surface of the frame 1, and two brake clips with opposite clamping surfaces are arranged in the frame 1, A rope channel 2 is formed between the clamping surfaces of the two brake clips, and the rope channel 2 is vertically opposite to the slit-shaped opening on the frame 1 , so that the traction wire rope 10 can pass up and down in the frame 1 . The two brake clips are arranged opposite to each other, and the opposite surfaces of the brake clips are clamping surfaces parallel to each other, and a friction plate 3 is arranged on the clamping surface of each brake clip. The two brake clips in this embodiment are both movable clips 4 , and the two movable clips 4 have the same structure and are arranged symmetrically in the frame 1 .

Embodiment 2

[0047] The structure of this embodiment is basically the same as that of Embodiment 1, and it is also the setting structure of double movable clamping blocks, and is provided with two brake trigger mechanisms; the front ends of the brake push rods 75 in the two brake trigger mechanisms respectively push Trigger braking is performed in the chute 6 of the movable clamp block 4 on each side.

[0048] The difference is that the rope channel 2 is an upper and lower channel that is surrounded by three sides and opened on one side by the frame 1, the brake clip and the end plate 8 ( Figure 5 ). The open side of the rope channel is convenient for installing the rope clamp on the elevator equipment that is not easy to disassemble, that is, the steel wire rope 10 on the elevator can enter the rope channel 2 through the open side, thus greatly facilitating the installation of the rope clamp .

Embodiment 3

[0050] Such as Figure 6 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, except that one of the two brake clips in the frame 1 is a movable clip 4, and the other is a fixed clip 9; the fixed clip 9 is fixed on the frame 1, and save the setting of a corresponding brake trigger mechanism. Therefore, in this embodiment, only the frame 1 on one side of the movable clamp block 4 is provided with a brake trigger mechanism, and the brake trigger mechanism includes a brake electromagnet 7, a compression spring 74, a brake push rod 75, and the like. Similarly, the braking electromagnet 7 is composed of a yoke 71, an armature 72 and an electromagnetic coil 73; the compression spring 74 is installed in the inner cavity of the braking electromagnet 7 (it can also be arranged outside the braking electromagnet) , the brake push rod 75 passes through the yoke 71 , the armature 72 and the compression spring 74 , and maintains a linkage structure with...

Abstract

The invention relates to a rope gripper. According to the structure of the rope gripper, two braking and clamping blocks with opposite clamping faces are arranged in a frame. A rope channel is formed between the clamping faces of the two braking and clamping blocks. The clamping faces of the braking and clamping blocks are provided with friction plates. At least one of the braking and clamping blocks is a movable clamping block capable of moving in the frame up and down. Tension springs capable of pulling the movable clamping blocks so that the back faces of the movable clamping blocks can be attached to the inner edge of the frame are arranged between the movable clamping blocks and the frame. The back faces, opposite to the corresponding clamping faces, of the movable clamping blocks are inclined faces so that the movable clamping blocks can form wedge-shaped blocks. The inner edge, attached to the back faces of the movable clamping blocks, of the frame is an inclined face combined with the back faces of the movable clamping blocks. By the adoption of the rope gripper, a lift car or a hoisted heavy object can be clamped immediately by the rope gripper no matter in the upward hoisting process or the downward sliding process, and vicious consequences caused by accidents are prevented.

Description

technical field [0001] The invention relates to a rope brake, in particular to a rope clamp. Background technique [0002] In recent years, accidents of elevators slipping, rushing to the top, and squatting at the bottom have occurred from time to time. In order to curb the occurrence of such accidents, elevators have been added to the No. Mandatory requirements for safety protection devices to prevent accidental movement of the car should be added to prevent vicious casualties caused by accidental movement of the car. [0003] Existing safety protection devices to prevent accidental movement of the car generally include the following three methods: [0004] The first way is to add a separate set of brakes on the basis of the original brakes as a redundant design. The disadvantage of this form is that if the car unexpectedly moves in the power failure state, the two brakes will act at the same time, which not only greatly increases the original adjusted braking torque, but...
