Description

Technical field:

[0001] The utility model relates to the field of TBM equipment, in particular to a support bracket used for pipelines such as TBM hydraulic pipes or water pipes. Background technology:

[0002] TBM (Tunnel Boring Machine, full name: full-section rock tunnel boring machine) is increasingly widely used in tunnel construction in water conservancy and hydropower, railways, transportation, urban underground projects, oil and gas pipelines, national defense, etc. Since most of the mechanical equipment in TBM equipment is driven by hydraulics, and TBM motors, hydraulic pumps, and industrial production have a large demand for water, the installation of pipelines of various sizes is also of great significance to the operation of the equipment.

[0003] At present, the hose near the rear-end drag cylinder of the TBM adopts the form of directly connecting the two ends of the hose to the hard pipe, and the hard pipe is fixed at both ends by a pipe clamp. Since the hose near the rear-end drag cylinder of the TBM is long and the pipeline moves frequently, during the initial excavation, the middle part of the hose is close to the equipment, and the probability of friction is high, which can easily cause frequent wear and pressure release of the pipeline. When the TBM is excavating, the hose pipeline must move forward with the main machine. When the TBM changes steps, the hose pipeline must move forward with the rear supporting equipment. The existing TBM water pipe pipeline uses a clamp connection method at the connection between the hose and the hard pipe. Therefore, frequent activities can easily cause the connection between the hose and the hard pipe to loosen or be damaged, affecting the normal excavation of the TBM. Summary of the invention:

[0004] The technical problem to be solved by the utility model is to provide a movable support bracket for TBM pipelines which can reduce the stress on the connection between the two ends of the hose and the hard pipe, and prevent the middle of the hose from completely hanging down onto the equipment and scratching the equipment.

[0005] The purpose of the utility model is achieved as follows: it comprises a bracket fixing beam, and the upper rear side of the bracket fixing beam is connected with a fixing plate by bolts;

[0006] It also includes a plurality of arc-shaped support brackets arranged up and down, wherein the arc-shaped support bracket includes an arc-shaped bottom plate, a rear vertical plate extending upward is fixed to the rear end of the arc-shaped bottom plate, a front vertical plate extending upward is fixed to the front end of the arc-shaped bottom plate, the rear vertical plate is connected to the bracket fixing beam by connecting bolts, an annular plastic guard plate is arranged outside the connecting bolts, the plastic guard plate is fixed to the rear vertical plate of the arc-shaped support bracket, and the front side edge of the plastic guard plate is in front of the front side edge of the connecting bolt;

[0007] The height of the middle part of the arc-shaped bottom plate is higher than the heights of the left and right ends.

[0008] The width of each arc-shaped support bracket (the distance between the front and rear vertical plates of the arc-shaped support bracket is the width) gradually increases from top to bottom, that is, the distance between the front and rear vertical plates of the arc-shaped support bracket at the top is the smallest, and the distance between the front and rear vertical plates of the arc-shaped support bracket at the bottom is the largest, which facilitates the placement of pipelines.

[0009] A supporting channel steel is arranged directly below each arc-shaped supporting bracket, and each arc-shaped supporting bracket is in contact with the supporting channel steel directly below it. The supporting channel steel is welded to the bracket fixing beam, and the supporting channel steel can play the role of supporting the arc-shaped supporting bracket.

[0010] The advantages of the utility model are: by installing the device in the middle of the hose, the stress on the two ends of the hose and the connection between the hard pipe is reduced; the middle of the hose will not all fall onto the equipment and scratch the equipment; a plastic guard plate is provided to prevent the pipeline from directly contacting the fixing bolts and causing scratches when the pipeline is moving; the device can make the hose pipeline layout more compact and increase the service life of the hose pipeline.
