Double Tube Fixing Clamp

Abstract

The invention relates to the technical field of heavy-duty vehicle pipeline fixing, in particular to a double-pipe fixing clamp mainly used for fixing water pipes of hydraulic retarders of commercial vehicles. The two petals are exactly the same, and they are separately buckled on the upper and lower sides of the steel pipe. The middle is connected by bolts, nuts and limit sleeves. It can also be fixed on the power assembly with a connecting bracket, so that the two water pipes can be fixed separately as a whole, or two pipes can be fixed together. The water pipes are connected together and then fixed with the powertrain. The number of pipeline fixing brackets is greatly reduced, saving space and cost. The clamp has a rubber wrapping layer, which can effectively protect the steel pipe from large deformation, and the rubber has a convex-concave structure to increase friction. The hoop wrapping range exceeds 310° and can effectively tighten the steel pipe. During the assembly process, the steel pipe is effectively compressed through rubber deformation, and the fixation is reliable.

Description

technical field [0001] The invention relates to the technical field of heavy-duty vehicle pipeline fixing, in particular to a double-pipe fixing clamp mainly used for fixing water pipes of hydraulic retarders of commercial vehicles. Background technique [0002] With the continuous development of high-speed logistics and the improvement of vehicle safety, retarders have become the standard configuration of high-speed vehicles. The cooling water pipe of the retarder runs through the front and back of the powertrain, and the high-temperature and high-pressure water flows through the water pipe, which requires reliable fixing of the pipe. The fixing points for pipelines on the powertrain are generally very limited, and in most cases, the inlet and outlet pipes are arranged together. Therefore, it is very necessary to develop a dual-pipe fixing device that occupies less space and is reliable. Furthermore, the wall thickness of the pipeline is relatively thin, so it is necessary...

Problems solved by technology

[0004] In order to solve the above-mentioned technical defects, the present invention provides a double-pipe fixing clamp, which can solve the problem that it is difficult to find a fixed point on the power assembly for the inlet and outlet water pipes of the retarder, the fixing bracket takes up a large space, and the fixing bracket of the retarder water pipe is unreliable. problem, and the clamp can effectively protect the steel pipe from large deformation, and it is fixed reliably, avoiding the change of the pipeline direction caused by the too small rigidity of the bracket during the operation of the car, and accidents
