Embodiment Construction

[0018] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0019] Such as Figure 1-3 As shown, a kind of elevator traction rope brake of the present invention, wherein there are three traction ropes 1, the same diameter, and parallel to each other in a straight line, the brake includes a rope clamping device rotating around the fixed shaft 21 and a blocking positioning device The blocking device of the rope clamping device. The rope clamping device includes two integrated rope clamping blocks, namely the rope clamping block 2 and the rope clamping block 4 . The fixed shaft 21 is arranged in the rope clamping block 2, and the fixed shaft 21 is provided with a reset spring. The two rope clamping blo...

Abstract

The invention relates to an elevator hoisting rope brake. The quantity of hoisting ropes is two or more, and the hoisting ropes are arranged in a linear way. The elevator hoisting rope brake is characterized by comprising a rope clamping device which rotates along a fixed shaft and a stop device for stopping and positioning the rope clamping device, wherein the rope clamping device comprises two rope clamping blocks of an integral type, a fixed shaft is arranged in one rope clamping block, the two rope clamping blocks are oppositely arranged at a certain interval, a strip-shaped clipper seam is formed between the two rope clamping blocks, the clipper seam is vertical to the cross section of the fixed shaft and is in a shape with two large ends and small middle part, the minimal width in the middle of the clipper seam is the diameter of one hoisting rope, and the stop device comprises a stop block which is fixed in the rotation direction of the rope clamping device. The elevator hoisting rope brake has large clamping force and good brake effect, is stable to brake, has little damage to the hoisting rope and the brake and can be reset without blocking.

Description

technical field [0001] The invention relates to a braking device for driving ropes, in particular to a rotating braking device for elevator traction ropes. Background technique [0002] Usually one end of the traction rope is fixed on the counterweight of the elevator, and the other end is fixed on the car, and the lift is realized by the forward and reverse rotation of the traction sheave. The multi-rope friction lifting form is a commonly used form, which has the advantages of large lifting capacity and high safety. At present, the direct braking objects of the common brakes are divided into two types: elevator guide rails and traction ropes. The structure of the brake for the guide rail is complicated and the cost is high. And the usually used brake for the traction rope adopts the form of two parallel plates clamping the rope to brake, and the required clamping force is large, which is prone to loosening and affects safety. Contents of the invention [0003] The inv...
