Steel strand pulling device

Technical Field

The invention relates to the technical field of strand pulling machines, in particular to a steel strand pulling device.

Background

With the market competition becoming more and more intense, the work center of gravity of each construction unit and enterprise is achieved by reducing the production cost, improving the production efficiency and pursuing the maximization of profit. At present, in the large-scale high-speed rail construction of China, a precast beam is an indispensable procedure in the high-speed rail, and steel strand blanking and reeving is a first procedure in prestress construction. The prior manual blanking reeving requires at least 5 to 6 people like 32-meter box girders, and the blanking reeving is carried out by 1.5 pieces of box girders at most every day. The manual blanking reeving labor intensity is high, a large amount of labor force is needed, the efficiency is low, and the next procedure is affected due to the fact that the progress cannot be kept up. The manual blanking reeving needs larger field space, and the blanking is completed firstly and then reeving is needed, so that the blanking length is not easy to control, and the steel stranded wires at the other end of the beam are often different in length or exceed the required length.

The strand pulling machine is an ideal cable pulling construction machine, and is a main tool for pulling steel strands through a duct in prestressed work for constructing bridges and large buildings. The pre-stressed steel strand pulling machine can advance and retreat, can be fast and slow, is small in size, light in weight, simple to operate and convenient to maintain, can be operated by two persons in the construction process, greatly reduces labor intensity and improves production efficiency.

The strand pulling machine is before carrying out steel strand wires and pulling a bundle work, generally need to fix the strand pulling machine, it is enough to penetrate steel strand wires through the inlet after finishing fixing, spread through the outlet, steel strand wires need to cut off steel strand wires after transmitting certain length, the guide cap need be sheathe in to the steel strand wires cut surface, current strand pulling machine has certain drawback when using, can't carry out quick safe cutting to steel strand wires, the unable convenient guide cap that installs additional for the steel strand wires cut surface, can't carry out convenient fixing to the strand pulling machine, its outlet and steel strand wires contact surface easily wear and tear, influence life, we propose a steel strand wires and pull a bundle device for this reason.
