Non-slip lifting hook based on gear and rack

Abstract

The invention discloses a non-slip lifting hook based on a gear and a rack. The non-slip lifting hook comprises a lifting hook body, a non-slip installation block is arranged at the upper end of the lifting hook body, the gear is fixedly arranged on the non-slip installation block, and a crank handle is coaxially installed on the gear; the lifting hook body is movably connected with a vertically-arranged non-slip rod, and the rack capable of being meshed with the gear is arranged on one side of the non-slip rod; a hook tip cover is arranged at the bottom end of the non-slip rod, a hook tip can be sleeved with the hook tip cover, a first locking hole is formed in the hook tip cover, a second locking hole matched with the first locking hole is formed in the hook tip, and the first locking hole and the second locking hole can be locked through a locking piece. The non-slip rod of the non-slip lifting hook is driven to move up and down through the gear and the rack, opening and closing of the lifting hook body are achieved conveniently and rapidly, operation is easy and convenient, manpower is saved, working efficiency is high, unhooking resistance is good, safety performance is high, and the non-slip lifting hook is light, high in strength, long in service life, good in practicability and worthy of being widely popularized.

Description

technical field [0001] The invention relates to a construction machine, in particular to an anti-slip hook based on a gear-rack. Background technique [0002] Cranes, also known as cranes, refer to multi-action hoisting machinery that vertically lifts and horizontally transports heavy objects within a certain range. The working characteristic of the crane is to do intermittent movement, that is, the corresponding mechanisms for taking materials, moving, and unloading in a working cycle are alternately working, and are widely used in industrial production, construction, freight terminals, warehousing and other industries. , mainly used to lift various goods. In addition to the power unit and the steel rope for hoisting, there are also hooks on the crane, and the hook is an important part of the crane. It plays an important role in the whole lifting process and bears all the loads of lifting. Its Safety directly affects the operation of the crane. During use, once the hook i...

Problems solved by technology

But there is following defect in anti-off design like this: because the anti-slip bar is close to the inwall of hook body hook tip, when taking out or replacing the sling, the anti-slip bar needs to be artificially pressed down toward the inner space of the suspension hook body. The sling is heavy and requires two people to operate, which wastes manpower; in addition, because the anti-slip rod occupies the opening area of ​​the hook body, if the size of the sling is large, the opening area between the anti-slip rod and the hook tip of the hook body is small. This increases the difficulty of replacing or taking out the sling and reduces work efficiency
