Problems solved by technology

In important occasions, the electric hoist is used to increase the protection function of the broken rope by using a balance bar, which is realized by fixing the two ends of the wire rope respectively. When transporting heavy objects, due to shaking or cable-staying, it is easy to cause the balance bar to swing, which makes the height of the wire rope aggravate the unbalance of the sling, causing inconvenience in use and increasing safety hazards

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Such as Figure 1-Figure 6 As shown, an electric hoist with a broken rope protection function includes a reel seat 1, a hook 4 and a movable pulley 5 fixed on the hook 4, and a reel machine 2 is fixed above the reel seat 1. One side of the reel seat 1 is fixedly provided with a pulley hanging plate 3, and a balance pulley 6 is arranged in the pulley hanging plate 6, and the steel wire rope 8 passes through the movable pulley 5 and the balance pulley 6 in turn, and the steel wire rope 8 at the balance pulley 6 places Wire rope clips 8 close to the pulley hanging plate 6 are fixedly arranged at both ends.

[0023] Such as figure 1 with figure 2 As shown, through the fixed wire rope clips 8 on the steel wire ropes at the two ends of the balance pulley 6, no matter which side of the wire rope breaks, the corresponding wire rope clips rise and are stuck with the ...

Abstract

The invention discloses an electric block with a rope breakage protection function. The electric block comprises a winding wheel base, a lifting hook, and a movable pulley fixed on the lifting hook; a winding wheel machine is fixedly arranged above the winding wheel base; a pulley lifting plate is fixedly arranged on one side of the winding wheel base; a balance pulley is arranged in the pulley lifting plate; a steel wire rope penetrates through the movable pulley and the balance pulley in sequence; and steel wire rope clamping blocks near the pulley lifting plate are fixedly arranged at two ends of the steel wire rope of the balance pulley. The steel wire rope clamping blocks clamped on the steel wire ropes at two ends of the balance pulley are used for reserving a safe gliding distance with the pulley lifting frame; and when the steel wire rope on one side is broken, the steel wire rope clamping blocks are ascended to clamp on the pulley lifting frame to guarantee no falling of weights.

Description

technical field [0001] The invention relates to an electric hoist with a rope breaking protection function, belonging to the technical field of electric hoists. Background technique [0002] When the general electric hoist adopts the balance pulley, there is no protection function for broken rope (wire rope). In important occasions, the electric hoist is used to increase the protection function of the broken rope by using a balance bar, which is realized by fixing the two ends of the wire rope respectively. When transporting heavy objects, the balance bar will easily swing due to shaking or cable-staying, which will cause the different heights of the wire ropes to aggravate the unbalance of the spreader, causing inconvenience in use and increasing safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric hoist with the function of rope breakage protection, using the wire rope clamps clamped on ...
