Description

Technical Field

[0001] This utility model belongs to the technical field of thermal insulation pipe processing equipment, and relates to a binding device for forming thermal insulation pipes, specifically a steel strap binding device for forming large-diameter steam thermal insulation pipes. Background Technology

[0002] Steam insulation pipes are generally composed of steel pipes and insulation layers installed on the outside of the steel pipes. In order to ensure that the insulation layer can be stably installed on the steel pipes, steel strapping needs to be wrapped around the outside of the insulation layer, and then an external protective layer is installed.

[0003] In existing technology, the binding of steel cable ties is done manually, with a person holding a steel cable tying machine to connect and secure the steel cable ties wrapped around the steel pipe. This method has the following problems:

[0004] 1. Manual operation and low binding efficiency greatly affect the production progress of large-diameter steam insulation pipes;

[0005] 2. The edges of steel cable ties are relatively sharp, and during manual operation, it is inevitable that the steel cable ties will cut the operators.

[0006] 3. Manual binding is not strong enough to guarantee the stability of the insulation layer.

[0007] Therefore, it is essential to propose a steel strapping device for forming large-diameter steam insulation pipes. Utility Model Content

[0019] The advantages and positive effects of this utility model are:

[0020] 1. The steel cable tie binding device used for forming large-diameter steam insulation pipes adopts a combination of welding and angle grinder cutting. The overlapping parts of the steel cable ties are welded by a welding head, which eliminates the risk of loosening when manually tied. The high-speed cutting of the angle grinder in sync with the process results in a smooth cut without burrs. This completely solves the problems of loosening caused by stress concentration at the knots in traditional methods, as well as the corrosion failure caused by sharp ends piercing the outer protective layer, greatly extending the service life of the product.

[0039] The lifting and extending of the welding head is achieved through the coordinated action of the lifting electric cylinder and the horizontal drive cylinder. When the steel cable tie coincides with the initial end after rotating one revolution with the steel pipe, the overlapping joint is welded and fixed.

[0040] While welding, the excess steel cable tie is cut off by the high-speed rotating grinding wheel of the angle grinder, resulting in a smooth cut without burrs, thus avoiding the problem of damage to the outer protective layer caused by the sharp ends of traditional iron wire.

[0041] Working principle:

[0042] This device is used in conjunction with a steel pipe loading trolley, which provides linear conveying, lifting and rotating motion of steel pipes.

[0043] In use, steel pipe 26 is located at the bottom of the device. The end of the steel cable tie guided by the device is fixed to the insulation layer of the steel pipe. Then, the steel pipe loading trolley drives the steel pipe to rotate clockwise. After one rotation, the end of the steel cable tie meets the steel cable tie that is being fed. At this time, the pressure cylinder extends forward and presses down to press the two steel cable ties together. At the same time, the welding head pressed on the two steel cable ties welds and fixes them together. The grinding wheel of the angle grinder cuts the steel cable tie, thereby completing the binding and fixing of the insulation layer on the large-diameter steel pipe.
