Traction device and method capable of increasing speed for winding heat-preserving strap around plastic pipe

Abstract

The invention provides a traction device and method capable of increasing the speed for winding a heat-preserving strap around a plastic pipe. The traction device and method capable of increasing thespeed for winding the heat-preserving strap around the plastic pipe are arranged on the plastic pipeline and correspond to the wall face. The heat-preserving strap is wound around the plastic pipeline. The traction device comprises multiple arc-shaped bases, two fixing rods, a fixing spring and a sliding block assembly. The multiple arc-shaped bases are sequentially clamped with one another end toend. A groove is formed in the top of each arc-shaped base. According to the traction device and method capable of increasing the speed for winding the heat-preserving strap around the plastic pipe,by means of mutual cooperation among the arranged multiple arc-shaped bases, the two fixing rods, the fixing spring and the sliding block assembly, thus a worker does not need to grab the heat-preserving strap with hands and carry out penetrating operation from a gap between the plastic pipeline and the wall face. Use of the worker is facilitated greatly. Meanwhile, the phenomenon that when the worker carries out penetrating operation on the heat-preserving strap, finger knuckles frequently collide and make contact with the wall face 1 or the plastic pipeline and are injured can be avoided.

Description

technical field [0001] The invention relates to the technical field of plastic pipe heat preservation equipment, in particular to a traction device and method capable of increasing the speed of a heat preservation belt winding a plastic pipe. Background technique [0002] Sewer pipes are generally made of two materials, plastic and metal, and plastic sewer pipes have a relatively weak wall when the temperature is low in winter in the north, and they are also easy to block the pipes. Therefore personnel often wraps insulation fabrics such as cloth strips, plastics on the pipe outer wall, but, because sewer pipes are often all set up against the wall. When people wind the insulation tape, they often need to use their hands to pass one end of the insulation tape through the gap between the pipe and the wall. , and therefore also vulnerable to injury. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the p...

AI Technical Summary

Problems solved by technology

[0002] Sewer pipes are generally made of plastic and metal, and when the temperature is low in winter in the north, the wall of plastic sewer pipes will become more fragile, and it is also easy to block the pipes

Therefore, personnel often wrap cloth strips, plastics and other thermal insulation fabrics on the outer wall of the pipe. However, because the sewer pipes are often set up against the wall

When people wind the insulation tape, they often need to use their hands to pass one end of the insulation tape through the gap between the pipe and the wall. , and thus also susceptible to injury
