Description

TECHNICAL FIELD

[0001] The utility model relates to a pipeline support anti -drop technical field especially relates to a kind of anti -drop steam pipeline support. BACKGROUND

[0002] In the industrial field, steam pipeline system is widely used in various production processes, such as power plants, chemical plants, etc. The safe and stable operation of steam pipeline is crucial to the whole production system, and as the key component of supporting and fixing steam pipeline, the performance of pipeline support directly affects the safety and reliability of pipeline system.

[0003] The basic composition of steam pipeline support:

[0004] 1. Beam: the main load-bearing component of the support, usually made of steel beam or other high-strength metal materials;

[0005] 2. Column: used to support the beam, transferring the weight of the pipeline to the ground or foundation structure;

[0006] 3. Pipe support: directly in contact with the steam pipeline, playing the role of supporting and fixing the pipeline;

[0007] 4. Hoop or clamp: used to further fix the connection between the pipeline and the pipe support or support, increasing the reliability of the connection.

[0008] The traditional steam pipeline support mainly focuses on the supporting function in design, usually composed of simple metal structures, such as steel beams, angle steels, etc. welded together. Its connection mode is mostly bolted or welded to the support structure of pipe gallery or building.

[0009] However, this traditional support has many problems. In terms of anti -drop, due to the lack of effective measures to deal with the transverse displacement of pipeline, when the pipeline generates transverse force due to thermal expansion and contraction or external load, the support is prone to disengagement, resulting in the loss of support for the pipeline and causing safety accidents. In terms of heat insulation performance, ordinary supports do not have heat insulation design, and the heat of high-temperature steam pipeline will be conducted to the support, making the support in high-temperature state for a long time. The present application aims to provide an anti -drop steam pipeline support, which considers the functions of anti -drop, heat insulation, damping guide, etc. in view of the shortcomings of the prior art, through special structure design, such as increasing the support structure at the bottom of the pipe rack to effectively increase the contact surface in the transverse thermal displacement direction of the pipeline, reducing the risk of disengagement; setting high-thermal insulation pad in the support to reduce heat conduction to the support part and protect the strength of the support; using the combination of damper and guide structure to control the displacement and vibration of the pipeline, ensuring the stability of the pipeline during operation. This anti -drop steam pipeline support can improve the safety and reliability of steam pipeline system, prolong the service life of the support and pipeline, reduce maintenance cost, and ensure the smooth progress of industrial production. Utility Model Content

[0010] In response to the shortcomings of the existing technology, the utility model provides an anti-detachment steam pipe support, which solves the problem of lack of effective response measures to the lateral displacement of the pipeline. When the pipeline generates lateral force due to thermal expansion and contraction or external load, the support is prone to detachment, causing the pipeline to lose support and cause safety accidents.

[0011] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0012] A steam pipe support with an anti-slipping structure, comprising a connecting plate, two clamps are provided above the connecting plate, and the steam pipe support with an anti-slipping structure further comprises: a crossbeam is fixedly connected to the lower surface of the clamp located below the two clamps, two clamps are fixedly connected to the inner wall of the crossbeam, a group of reinforcing plates are fixedly connected to the left and right sides of the crossbeam, a fixing plate is provided below the connecting plate, two dampers are provided above the fixing plate, thermal insulation pads are provided on the opposite surfaces of the two clamps, clamps are fixedly connected to the front and rear sides of the connecting plate, screws are fixedly connected to the upper surfaces of the two clamps, and the crossbeam is fixedly connected to the connecting plate.

[0013] Preferably, the two groups of reinforcing plates are fixedly connected to the connecting plate, the connecting plate is provided with a card slot on both the front and rear sides, and the two card slots are movably connected to the fixed plate.

[0014] Preferably, the upper surface of the fixing plate is fixedly connected to two screw rods 2, the annular side surfaces of the two screw rods 2 and the two screw rods 1 are threadedly sleeved with nuts, and the two screw rods 1 and the two screw rods 2 are movably sleeved with two dampers respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A wider connecting plate is used as a whole. When the pipeline produces lateral thermal displacement due to high temperature, the larger contact surface can disperse the force applied by the pipeline to the bracket, making it less likely for the bracket to detach due to excessive local force. Symmetrical clamps and increased lateral reinforcement plates are also used to enable the bracket to maintain balance when subjected to lateral force, preventing the bracket from falling off due to uneven force. The bracket is made of alloy steel as a whole. This material itself has high yield strength and tensile strength and can withstand greater external force without deformation or damage. Insulation pads are installed inside the two clamps. The insulation pads are made of vermiculite and have a low thermal conductivity coefficient. They can effectively prevent heat from being transferred from the pipeline to the bracket, thereby extending the service life of the bracket.

[0017] 2、When the pipeline occurs transverse displacement, the damper is stretched to generate an elastic force opposite to the displacement direction, limiting the excessive displacement of the pipeline, two dampers are installed on the connecting plate and the fixed plate, the fixed plate is fixedly connected with the stand, the connecting plate is movably connected with the fixed plate, and when displacement occurs, the pipeline can be guided to move in the transverse displacement according to the predetermined direction, so that the pipeline is prevented from deviating or twisting due to uneven stress, and the risk of the support falling off is reduced.
