Embodiment Construction

[0020] Such as figure 1 , 2 , 3, 4, and 5 show a specific embodiment of an automatic unhooking safety hanger, including a main body 1, a hanging nail 2 and a driving device 3 installed on the main body 1. The main body 1 is hinged with two hook plates 4 through the rotating shaft 7 at opposite positions, so that the two hook plates can rotate around the rotating shaft to realize the separation / closing of the lower ends of the two hook plates. The driving device 3 is used to drive the two hook plates 4 to turn over in the opposite direction to separate them. Specifically, the driving device 3 is an up and down driving device, and the telescopic end of the driving device 3 is equipped with a driving body 5. The driving device in the example used an electric push rod, and the driving body was installed on the rod end of the electric pushing rod, so that the driving device drove the driving body to move up and down. The inner sides of the two hook plates 4 are provided with a gu...

Abstract

The invention discloses a safety lifting appliance capable of automatic hooking and unhooking. The safety lifting appliance comprises a main body, a hooking nail and a driving device arranged on the main body, wherein two hook plates are hinged to the main body in opposite positions, holes are formed in the two hook plates, the driving device is used for driving the two hook plates to overturn inthe reverse direction for separation, the hook plates can be closed in the opposite direction under the action of gravity of the hook plates, flange plates are arranged on the two sides of the liftingnail, the edges of the flange plates are provided with downward protrusions, when the two hook plates are closed, the two flange plates are inserted into the two holes respectively, and the protrusions can prevent the hook plates from sliding out from the edges of the flange plates. According to the safety lifting appliance, the hook plates are driven to open or allow the hook plate to be closedthrough the driving device, the hook plates are provided with the holes, the lifting nail are provided with the flange plates, the flange plates are provided with the downward protrusions, when the hook plates are opened, the flange plates are separated from the holes to realize unhooking, when the hook plates are closed, the flange plates enter the holes to realize hooking, and the situations that the hook is hooked falsely and the hook is unhooked accidentally are prevented.

Description

technical field [0001] The invention relates to the field of construction hoisting equipment, in particular to an automatic lifting safety hanger. Background technique [0002] At present, in the hoisting operation of building structural parts, the removal and hanging of the hook is usually done manually. Due to the large size of the components, ladder climbing operations are required, and the safety guarantee is poor and the efficiency is low. The use of automatic hook removal for hoisting operations can effectively improve the safety of component hoisting operations. [0003] Therefore, the present invention proposes a simple and reliable automatic detachment hanger form. Contents of the invention [0004] The purpose of the present invention is to provide an automatic unhanging safety spreader, which solves the problems of automatic unhanging and detachment of the spreader. [0005] In order to solve the problems of the technologies described above, the present invent...
