Description

Double power pipe pusher

technical field

The invention relates to pipeline construction equipment, in particular to a pipe pushing equipment.

Background technique

Pipeline transportation is one of the three major modes of transportation in modern times. Due to its advantages of high efficiency, low cost, less land occupation and less environmental impact, it is more and more widely used in energy supply, petrochemical industry and residential living systems. The lifeline of the city. Horizontal directional drilling technology is currently the most widely used technology for pipeline laying at home and abroad. However, in the process of directional drilling, due to the complexity of geology and the influence of factors such as the rated tensile force that the drill pipe can bear, there are still many limitations. , In the horizontal directional crossing of large-diameter, long-distance and complex geological rivers, problems such as plugging and sticking of drills and drill pipe breakage are prone to occur. In view of the above situation, German Herrenknecht combined the characteristics of micro-tunnel construction and horizontal directional drilling technology to propose the direct pipe laying method. The construction technology has the advantages of small construction area, fast speed and retractable. The direct pipe laying method allows prefabricated pipes to be laid in a single continuous pipe, with the help of a thrust device "pipe pusher", into the ground for work. However, the above pipe pusher uses a long-stroke, high-thrust hydraulic cylinder to directly push the pipe. Such a hydraulic cylinder has greater manufacturing difficulty and higher manufacturing cost, and the pipe pusher has larger equipment and requires a larger construction site. The pipe holder used in the above pipe pusher is a hydraulic radial active clamping, which requires a targeted clamping hydraulic cylinder, which further increases the equipment cost.

SUMMARY OF THE INVENTION

In view of this, the present invention provides a dual-power pipe pusher.

Its technical solutions are as follows:

The key point of a dual-power pipe pusher is that it includes two groups of propulsion mechanisms, and the two groups of propulsion mechanisms are provided with the same pipe-holding seat;

The advancing direction is parallel, and a clamping and holding tube is provided in the through hole of the pipe, and the center line of the clamping and holding tube is parallel to the hole center line of the through hole. A wedge-shaped mechanism is arranged between the outer cylinder wall and the fixed seat;

When the clamping and holding tube is axially relative to the fixed seat, the wedge-shaped mechanism makes the clamping and holding tube radially inwardly shrink.

By adopting the above technical solution, the clamping between the clamping tube and the pipe is realized by the wedge-shaped mechanism, and no special clamping power device is required, which reduces the equipment manufacturing cost and maintenance cost, and reduces the failure rate.

Preferably, the clamping and holding tube includes a shaped cylinder and at least two arc-shaped slips, the arc-shaped slips are arranged at the same end of the shaped cylinder, and all the arc-shaped slips are located at the same end of the shaped cylinder.
