A high-density polyethylene outer protective pipe clamping device

Abstract

The invention discloses a high-density polyethylene outer protection pipe clamping device. The high-density polyethylene outer protection pipe clamping device comprises a high-density polyethylene outer protection pipe support, the front end and the rear end of one side of the high-density polyethylene outer protection pipe support are each provided with a winding belt fixing ring, and the positions, opposite to the winding belt fixing rings, of the other side of the high-density polyethylene outer protection pipe support are provided with clamping devices; each clamping device comprises a supporting platform, a motor is arranged on each supporting platform, and is connected with a speed reducer, each speed reducer is connected with a rotating shaft, each rotating shaft is sleeved with a clamping gear, a clamping device is arranged above each clamping gear, a winging belt fixing device is arranged on each rotating shaft, and a winding belt is arranged between each winding belt fixing device and the corresponding winding belt fixing ring. The mechanical manner is adopted for fastening, the fastening effect is improved, the safety of he construction site is ensured, and the labor cost is also saved.

Description

technical field [0001] The invention relates to the field of fastening high-density polyethylene outer protective pipes, in particular to a clamping device for high-density polyethylene outer protective pipes. Background technique [0002] In recent years, prefabricated direct-buried jacketed pipes have been widely used in various pipelines for heating, cooling, oil transportation, and steam transportation due to their simple construction and remarkable energy-saving and anti-corrosion effects. The high-density polyethylene outer protection pipe sometimes needs to be placed for a period of time after production is completed, because the diameter of the pipe used is getting larger and larger, and at the same time, the end of the high-density polyethylene outer protection pipe will have a certain internal shrinkage due to stress. , will not be as round as steel pipes, which will inevitably cause difficulties in threading pipes in the process of threading pipes, and virtually i...
