Embodiment Construction

[0015] Such as figure 1 , 2 Shown in the middle: The wire rope break protection system has a safety rod device for synchronous lifting with the clamp suspension beam, a locking mechanism for tightening and releasing the safety rod device, and a control device for controlling tightening and releasing. A sensing device that provides a wire rope break signal to the control device; the lifting safety rod device is a cylindrical safety rod 13 surrounded by layers of annular bosses, each boss has a trapezoidal cross-section; the safety rod The lower end is fixed on the clamp beam or hanging beam. The safety rod is covered with an upper guide sleeve 7. The upper guide sleeve is a cylindrical hollow sleeve, which is always sleeved on the safety rod, which ensures that the safety rod is always up and down in the vertical direction mobile. The upper guide sleeve is fixed on the workbench 13 by bolts B1, nuts B2, and washers B3 through the upper guide sleeve backing plate. The safety lever ...

Abstract

The present invention discloses a wire cable rupture protection system which comprises the following components: a safety rod device which is used for lifting synchronously with the suspending beam of a clamper, a locking mechanism which is used for locking and unloosening, a control device used for controlling the locking and unloosing, and a sensing device which is used for providing a wire cable rupture signal to the control device. The lifting safety rod device is always in the locking range of the locking mechanism. The locking mechanism is positioned on a stationary worktable (13). The sensing device monitors the condition of wire cable rupture, and when the wire cable is ruptured, the sensing device transmits the rupture signal to the control device; a reset device (12) operates and the locking mechanism locks the safety rod device so that the heavy object does not fall off and a protection effect is provided. The wire cable rupture protection system of the invention is especially suitable for the problem of wire cable rupture occurred on the travelling crane with small height and has the functions of protecting the wire cable and prolonging the service lifetime of the wire cable. Furthermore the wire cable rupture protection system can be used in various dangerous working conditions and the serious accident is prevented.

Description

Technical field [0001] The invention relates to the technical field of steel wire rope protection, in particular to a steel wire rope fracture protection system in the lifting industry. Background technique [0002] At present, there is still no effective way to solve the problem of wire rope breakage in the lifting industry. If the wire rope breaks, a major safety accident will occur. The only way is to regularly maintain and maintain the wire rope. If there are cracks in the wire, the wire rope must be replaced immediately to prevent major accidents. However, when there are inspection omissions and incorrect maintenance, major safety accidents may still occur. Therefore, it is necessary to design a wire rope break protection system. Summary of the invention [0003] In order to overcome the shortcomings of the prior art and solve the problem of sudden breakage of a steel wire rope, the present invention provides a wire rope breakage protection system. It can prevent the wire r...
