Wire clamping device for preventing lead from slipping away during tension stringing

Abstract

The invention discloses a wire clamping device for preventing a lead from slipping away during tension stringing. The wire clamping device comprises a main frame body, an upper clamping plate, a lower clamping plate and a revolving rod, wherein a speed detector, an electromagnetic push rod, a push rod support frame and two guide rollers are arranged on the main frame body; the upper clamping plate is fixed on the main frame body; a right end of the lower clamping plate is connected with the main frame body in a sliding way; an upper end of the revolving rod is rotationally connected with a left end of the upper clamping plate; a middle part of the revolving rod is rotationally connected with a middle part of the lower clamping plate; connecting rods are hinged to a front side and a back side of a lower end of the revolving rod respectively; right ends of the two connecting rods are connected with the main frame body in a sliding way, and a pull ring is hinged to the right ends of the two connecting rods; the pull ring is connected with a ground anchor; a stay wire is fixed on the revolving rod; the other end of the stay wire sleeves an extension shaft of the electromagnetic push rod; and the main frame body is provided with an elastic part for driving the lower clamping plate to be clamped upwards. The wire clamping device has the advantages of simple structure, saving of materials, high stability and wear resistance. The lead is stuck in time through coordination and cooperation of components, thereby achieving safety and reliability, and saving time and labor.

Description

technical field [0001] The invention belongs to the technical field of electric construction and installation equipment, and in particular relates to a wire clamping device for preventing the wire from running away when the tension is paid out. Background technique [0002] At present, hydraulic tensioners and tractors are mostly used in the construction of electric power construction tension wires. The failure of hydraulic components during construction leads to the disappearance of the tension during wire installation, and the running of the unfolding wires occurs instantly. In addition, there will also be wire breakage or breakage at the joint during construction. Under the action of the traction force and the wire's own gravity, the wire will speed up and run away instantly. Once the wire slip occurs, the entire pay-off channel will become very dangerous and endanger the construction channel. safety of construction workers. At present, the wire clamps used in constructi...

Problems solved by technology

[0002] At present, hydraulic tension machines and traction machines are mostly used in the tension stringing construction of electric power construction. The failure of hydraulic components during construction causes the tension to disappear during stringing, and the wires slip away instantly.

In addition, wire breakage or joint breakage may also occur during construction. Under the action of traction force and the gravity of the wire itself, the wire speeds up and slips away instantly. Once the wire slips, the entire pay-off channel will become very dangerous and endanger the construction channel. safety of construction workers

At present, the wire clamps used in construction are all static anti-slipping wires, and there is no dynamic anti-slipping device in the construction of electric tension stringing, so it is necessary to develop a device that can detect and act in time when the wire slipping occurs. Prevent the extended wires from running away quickly, and avoid the occurrence of accidents in the extended wire passage
