Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline support, in particular to a pipeline support device for port construction. BACKGROUND

[0002] In the process of port construction, it is often necessary to lay pipelines for respective purposes. The pipelines are generally made of PE pipes. During laying and construction, a support device needs to be set up to support the pipeline body and limit and fix it. In the prior art, two groups of semicircular ring structure members are used to wrap and fix the pipeline, and then the pipeline is supported by a base.

[0003] However, the existing pipeline support and positioning mode using two semicircular rings has poor adaptability to changes in pipe diameter. Different pipe diameters require different sizes of rings, which are troublesome to replace. If the semicircular rings are not replaced, the two semicircular rings have a small clamping contact surface with the pipeline, which affects the pipeline support and positioning effect and causes the pipeline to be subjected to a relatively serious local stress. Moreover, the existing pipeline support device can only achieve a simple support function and has poor functionality. SUMMARY

[0004] The present application is proposed to solve the problems in the prior art and provides a pipeline support device for port construction.

[0005] To achieve the above object, the present application adopts the following technical scheme:

[0006] The pipeline support device for port construction comprises a bottom plate and further comprises:

[0007] A pipeline support part, which comprises two support seats arranged on the bottom plate through supports, and two clamping and positioning mechanisms arranged on the two support seats, respectively, for supporting and positioning two to-be-connected pipe bodies, and a connecting flange arranged on the contact surface of each to-be-connected pipe body;

[0008] and an auxiliary positioning mechanism arranged on the support seat and connected with the clamping and positioning mechanism, for assisting in positioning the connected pipe body.

[0009] The two auxiliary positioning mechanisms are provided with a sealing assembly for sealing the connection position of the two connecting flanges.

[0010] Preferably, the clamping and positioning mechanism comprises a plurality of rotating rings arranged on the support seat in a circumferential uniform manner, an adjusting screw threadedly arranged on the support seat and connected with the rotating ring in a sliding manner, a clamping plate arranged at the end of the adjusting screw, and a first rubber gasket arranged on the clamping plate.

[0011] Preferably, the inner wall of the rotating ring is fixed with a guide strip, and the adjusting screw is provided with a guide groove for sliding of the guide strip.

[0012] Preferably, the clamping positioning mechanism further comprises a driven bevel gear arranged on each rotating ring and a bevel gear ring rotatably connected to the support base and simultaneously engaged with the plurality of driven bevel gears.

[0013] Preferably, the auxiliary positioning mechanism comprises a plurality of connecting seats fixed on the support base at equal intervals in the circumferential direction, a pushing part movably connected to the connecting seat, a positioning part arranged at the end of the pushing part and movably abutting against the connecting flange, a movable rod movably connected to the pushing part, and a sleeve ring movably connected to the end of the movable rod away from the pushing part, wherein the sleeve ring is rotatably connected to the adjusting screw through a bearing.

[0014] Preferably, the positioning part comprises an outer ring movably connected to the pushing part, a plurality of baffles slidingly connected to the outer ring at equal intervals in the circumferential direction, and a flexible expansion rod arranged between the baffles and the outer ring, wherein the baffles are provided with second rubber gaskets, and the side of the baffles away from the second rubber gaskets is provided with an extrusion inclined surface movably abutting against the connecting flange.

[0015] Preferably, the pushing part comprises a pushing rod rotatably connected to the connecting seat through a pin shaft, a sliding block movably connected to the end of the pushing rod away from the connecting seat, a fixed ring fixed on the pushing rod, a first elastic element connected to the fixed ring and sleeved on the outside of the pushing rod, and a sliding seat connected to the end of the first elastic element away from the fixed ring, wherein the sliding seat is slidingly connected to the pushing rod and movably connected to the end of the movable rod through a pin shaft, and the sliding block is arranged on the baffle.

[0016] Preferably, the baffle is provided with a sliding groove for sliding of the sliding block, and a second elastic element is arranged between the inner wall of the sliding groove and the sliding block.

[0017] Preferably, the sealing assembly comprises a conical rubber block and an annular pressing block movably abutting against the conical rubber block, wherein the conical rubber block is connected to the outer ring of one of the auxiliary positioning mechanisms, the annular pressing block is connected to the outer ring of another auxiliary positioning mechanism, and the conical rubber block movably abuts against the outer side wall of the connecting flange.

[0018] Preferably, the conical rubber block is internally provided with a flexible metal spring piece, and the inner wall of the outer ring connected to the conical rubber block is fixed with a positioning ring connected to the flexible metal spring piece.

[0019] Compared with the prior art, the pipe supporting device for port construction provided by the present application has the following beneficial effects:

[0020] 1. The pipeline support device used in port construction drives all rotating rings to rotate synchronously through a bevel gear ring, ensuring that each clamping plate moves synchronously and the clamping force is evenly distributed. The synchronous diameter changing mechanism (bevel gear ring + adjusting screw) enables single-drive adaptation to multiple pipe diameters, solving the problem of frequent replacement of traditional semi-circular rings to adapt to different pipe diameters. The circumferentially distributed clamping plates increase the contact area with the pipeline and avoid uneven force on the pipeline.

[0021] 2. The pipeline support device used in port construction uses a clamping and positioning mechanism that is linked to an auxiliary positioning mechanism during the clamping and positioning process. This allows the pushing part to be elastically buffered while the clamping and positioning mechanism continues to tighten, preventing overpressure damage to the connecting flange, until the clamping and positioning of the pipe is completed. The operation is simple and convenient, significantly improving construction efficiency and safety.

[0022] 3. The pipeline support device used in port construction automatically operates the sealing component when the auxiliary positioning mechanism is working, pushing the conical rubber block to cooperate with the annular pressure block, automatically sealing the flange connection gap, preventing media leakage, and improving the sealing effect of the pipeline connection.
