Hole forming device for hoisting steel cable strand threading

Abstract

The invention provides a hole forming device for hoisting steel cable strand threading and belongs to steel cable strand threading devices. The hole forming device is characterized by comprising a rack, a hole perforating rod, a steel cable box, a box cover, a locking bolt, a box groove, a cable winding fork, a shifting rod, a rotary shaft, a rear pulley, a front pulley, a cable fastener, a handle, a pedal shaft, a pedal, a counter weight and a guide pipe; the steel cable box and the cable winding fork are mounted at the rear end of an upper frame of the rack; the hole perforating rod with the rear end section being a sharp-end section is mounted on the rack; the pedal, the pedal shaft, the rear pulley, a pulling rope and a revolving plate are mounted on the rack; the hole perforating rod is made to move backwards to perforate a hole in a steel cable so that strand threading of the steel cable can be conducted; the counter weight, the front pulley and a counter weight rope are mounted on the rack to drive the hole perforating rod to move forwards and return; hole perforating and stranding threading can be completed once when the pedal is pedaled once; the hole forming device is convenient and reliable to use, capable of saving labor, low in cost and high in utilization rate.

Description

technical field [0001] The invention belongs to a wire rope threading device, in particular to a hole-forming device for hoisting a steel wire rope. Background technique [0002] In building construction, hoisting operations are ubiquitous, and hoisting equipment and the installation of hoisting equipment and the hoisting process have always been the focus and difficulty of each construction unit's control. In recent years, hoisting equipment such as gantry cranes and tower cranes have been used in construction The frequent accidents, even the tragedies of aircraft crash and human death, have threatened human life and caused great economic losses to the enterprise. The reasons for this are mainly in several aspects: poor technical quality of hoisting personnel and hoisting The foundation and foundation of equipment installation are not firm enough to cause the crane to collapse, and the objects to fall due to the breakage of the rope during the hoisting process. Therefore, t...

[0002] In building construction, hoisting operations are ubiquitous, and hoisting equipment and the installation of hoisting equipment and the hoisting process have always been the focus and difficulty of each construction unit's control. In recent years, hoisting equipment such as gantry cranes and tower cranes have been used in construction The frequent accidents, even the tragedies of aircraft crash and human death, have threatened human life and caused great economic losses to the enterprise. The reasons for this are mainly in several aspects: poor technical quality of hoisting personnel and hoisting The foundation and foundation of equipment installation are not firm enough to cause the crane to collapse, and the objects to fall due to the breakage of the rope during the hoisting process. Therefore, the bearing capacity of the hoisting rope and wire rope must meet the requirements, and the quality of the manual fixation of the spreader must be effectively improved. control, wherein the breaking force of the steel wire rope should be within the allowable range, so the threading and knotting of the thick diameter steel wire rope (that is, wearing a small diameter steel wire rope at the rope head of the thick diameter steel Knot) has always been a technical problem that the technicians of the construction unit have been trying to explore and solve. The existing steel wire ropes are usually drilled through the beam holes on the thick diameter steel wire ropes manually, which is time-consuming and laborious, and the efficiency is low. Details See the "Technology and Research on Wire Rope Threading and Winding Method" recorded in the magazine "Lifting and Transportation Machinery", but there is no similar or similar content to the technical solution declared by the patent of the present invention
