Technical Field
The utility model relates to the technical field of crane hoisting mechanism equipment, in particular to a locking rope detection device for a fixed end of a steel wire rope.
Background
In the use process of the lifting mechanism of the crane, the steel wire rope can be loosened or broken due to various reasons, if too much rope is loosened, the steel wire rope can be wound on the winding drum poorly, a jump groove is caused, and the steel wire rope can be damaged or broken seriously. Therefore, the method is particularly important for rope loosening and rope breakage detection of the steel wire rope.
Disclosure of Invention
The utility model provides a device for detecting a locking rope at a fixed end of a steel wire rope, which solves the problem that the detection of the loosening of the steel wire rope is not timely in the prior art.
The technical scheme of the utility model is realized as follows:
a locking rope detection device of wire rope stiff end includes: the device comprises a mounting shaft, a fixed end pulling plate and a balance plate, wherein the mounting shaft is mounted on a crane beam, the fixed end pulling plate is mounted on the mounting shaft, and the balance plate is in running fit with the fixed end pulling plate through a first rotating shaft; wedge sleeve sets are symmetrically arranged on two sides of the balance plate by taking the first rotating shaft as a center, and are connected with the steel wire rope fixed end of the crane; the wedge body and wedge sleeve group is in running fit with the balance plate through a second rotating shaft; one side end of the balance plate is provided with a matching group; and a limit switch is arranged on the fixed end pulling plate.
Preferably, the counterweight group is fixedly connected with one side end of the balance plate through a bolt.
Preferably, the limit switch is mounted on a switch mounting plate, and the switch mounting plate is fixedly connected with the fixed end pulling plate through bolts.
The working principle of the utility model is as follows:
when the steel wire ropes at the two ends of the wedge body wedge sleeve group are not long, namely when the steel wire ropes are loosened or broken, unbalance conditions can occur at the two ends of the balance plate, the balance plate can rotate along the first rotating shaft and the fixed end pulling plate, the balance plate can deflect towards one side of the balance plate due to the addition of the balance weight group, and then the balance plate can trigger the limit switch, so that rope loosening signals are fed back to the controller of the crane in time, and the crane stops lifting.
The beneficial effects of the utility model are as follows:
the condition of rope loosening or rope breakage of the steel wire rope can be timely detected, the crane is informed to stop running, and the steel wire rope is effectively prevented from being damaged or broken.
Drawings
In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings that are required in the embodiments or the description of the prior art will be briefly described, it being obvious that the drawings in the following description are only some embodiments of the utility model, and that other drawings may be obtained according to these drawings without inventive effort for a person skilled in the art.
