Problems solved by technology

The existing problems are: the pipeline is easy to deviate, and it is blocked on the wall of the tunnel during the process of traveling, so it is blocked, and the pipeline laying cannot be completed quickly and smoothly; and even if it is not stuck, there will be a problem that the quality of the two pipelines is not high.

Embodiment Construction

[0014] Such as Figure 2-4 As shown, the power device for pipe jacking mainly includes a jack 3 and a support for supporting the jack.

[0015] Wherein said jack 3 is provided with four, and the specification of four jacks is exactly the same. The rear end coaxial line of each jack 3 is fixed with a pinion gear 5; the parameters of the four pinion gears 5 are equal and all mesh with a central bull gear 6, and the four pinion gears 5 are evenly arranged around the axis of the central bull gear 6; Four small gears 5 are located in an external gear 7 and are all meshed with the external gear 7; the external gear 7 is fixed on the bracket 8; the central bull gear 6 is coaxially equipped with a driving gear 9, and the driving gear 9 passes through the transmission The gear 10 is connected with the drive motor 11; the drive motor 11 is fixed on the bracket 8.

[0016] During pipe jacking construction, four jacks are used to exert force on four points on the end surface of the pipe...

Abstract

A power device for jacking pipes comprises four jacks and a support for supporting the jacks and is characterized in that the rear end of each jack is coaxially provided with a small gear, parameters of the four small gears are identical and meshed with a center large gear, and the axes of the four small gears around the center large gear are evenly distributed. The four small gears are located in an outer gear ring and meshed with the outer gear ring. The outer gear ring is fixed on the support. A driving gear is coaxially installed on the center large gear, and the driving gear is connected with a driving motor through a transmission mechanism. The driving motor is fixedly installed on the support. The device can prevent pipes from moving off course in the advancing process, prevent blocking of the pipes, improve pipe abutting connection coaxility and improve the abutting connection quality.

Description

technical field [0001] The invention relates to a device for pipe laying in municipal engineering, especially a power device for pipe jacking. Background technique [0002] At present, in municipal engineering, the laying of underground pipelines adopts the pipe jacking process, which is to push the pipeline 2 into the pre-dug tunnel 1, such as figure 1 shown. And when pipe jacking, adopt jack to implement, the rear end of jack is fixed on the support, and the front end is that telescoping end pushes on the end face of pipeline, then starts jack to promote pipeline and advances. The existing problems are: the pipeline is easy to deviate, and it is blocked on the wall of the tunnel during the process of traveling, so it is blocked, and the pipeline laying cannot be completed quickly and smoothly; and even if it is not stuck, there will be a problem of poor quality of the butt joint of the two pipelines. Contents of the invention [0003] In order to overcome the shortcomi...
