Abstract
Description
Technical Field
[0001] The utility model relates to a low-friction heat-insulating sliding bracket for a steam pipeline. Background Art
[0002] The common practice of the polytetrafluoroethylene heat insulation and drag reduction plate in the steam pipe heat insulation sliding bracket is to simply fix it with the embedded parts of the concrete or steel structure bracket. During the operation, many brackets have the phenomenon of polytetrafluoroethylene heat insulation and drag reduction plate falling off. The contact surface of some brackets changes due to the falling of polytetrafluoroethylene heat insulation and drag reduction plate, and the friction coefficient increases, which leads to the increase of the force on the bracket. In reality, some brackets also tilt or deform due to the increase of force, resulting in a large amount of cost for bracket reinforcement in the later stage. In addition, in the current design, the steam pipe heat insulation bracket generally achieves that the heat insulation bracket and the steam pipe do not have relative displacement through the static friction between the upper and lower pipe clamps of the heat insulation bracket and the steam pipe. However, in actual operation, some pipe brackets have reduced the strength of the heat insulation tile due to the long operation time and the carbonization of the soft heat insulation material between the heat insulation tile and the pipe, which leads to the reduction of the static friction between the heat insulation bracket and the steam pipe, which is not enough to maintain the stable state between the steam pipe and the heat insulation bracket, resulting in the relative displacement of the steam pipe and the heat insulation bracket, resulting in the failure of the pipe bracket falling off from the civil support surface. In addition, in actual cases, steam pipes are laid along the walls of existing buildings or multiple rows of steam pipes are laid side by side. The insulation bracket connection bolts are too close to the wall or adjacent pipes, which affects the installation efficiency and quality of the bracket. The utility model aims to solve the problem that the polytetrafluoroethylene insulation board of the commonly used sliding bracket for steam pipes is easy to fall off, the problem that the insulation bracket and the steam pipe are relatively displaced, resulting in bracket failure, and the inconvenience of installing the steam pipe insulation bracket when it is close to obstacles, thereby improving the safety of steam pipe operation and the convenience of bracket installation in special scenarios. Summary of the invention
[0003] The problem to be solved by the utility model is to provide a low-friction heat-insulating sliding bracket for steam pipes. The bracket is used as a plane sliding bracket for laying overhead steam pipes, which helps to improve the safety and reliability of the operation of the pipe steam network, has stronger operability when multiple pipes are laid side by side, and is more convenient to use.
[0004] The technical solution provided by the utility model is: a low-friction heat-insulating sliding bracket for a steam pipe, comprising a pipe clamp and a bracket frame supporting the pipe clamp, the pipe clamp comprising an upper pipe clamp and a lower pipe clamp, the upper pipe clamp and the lower pipe clamp are respectively integrally cast with the heat-insulating tile and then connected to the steam pipe by bolts, and a thrust piece is provided on the steam pipe to limit the relative displacement between the pipe clamp and the steam pipe; the bracket frame comprises a pipe support vertical plate, a pipe support upper bottom plate, a polytetrafluoroethylene heat-insulating drag-reducing plate and a pipe support lower base plate, which are sequentially connected from top to bottom.
[0005] There are multiple thrust members, which are arranged at the front and rear sides of the pipe clamp and welded to the steam pipe along the four sides of the pipe. The relative displacement between the steam pipe and the insulation bracket is limited by the contact between the soft insulation material, the insulation tile of the insulation bracket and the pipe clamp. A silica aerogel insulation pad is arranged between the thrust member and the pipe clamp.
[0006] The connecting line of the two bolt connection positions of the upper pipe clamp and the lower pipe clamp forms an angle of 45° with the radial horizontal line of the pipeline.
[0007] A pipe support rib plate is arranged between the pipe clamp and the upper bottom plate of the pipe support, the pipe support vertical plate and the pipe support rib plate are respectively welded to the upper bottom plate and the pipe clamp, and a stainless steel plate is welded to the bottom of the upper bottom plate of the pipe support to form the upper drag reduction surface of the bracket; a plurality of round steels are welded to the lower base plate of the pipe support, a plurality of circular holes corresponding to the plurality of round steels are arranged at the bottom of the polytetrafluoroethylene thermal insulation and drag reduction plate, and the lower base plate of the pipe support is connected to the polytetrafluoroethylene thermal insulation and drag reduction plate by the plurality of round steels passing through the plurality of circular holes.
[0008] The pipe support upright plate, pipe support rib plate, pipe support upper bottom plate and stainless steel plate constitute the root structure of the thermal insulation bracket. The pipe support upright plate and rib plate are welded to the pipe clamp to connect the pipe part and the root of the thermal insulation bracket. The pipe support upper bottom plate is welded to the pipe support upright plate and rib plate to form a supporting structure. The stainless steel plate is welded under the pipe support upper bottom plate to form the upper drag reduction surface of the bracket.
[0009] The polytetrafluoroethylene heat-insulating and drag-reducing blocks, round steel, and the lower base plate of the pipe support constitute the heat-insulating and drag-reducing layer at the lower part of the heat-insulating support.
[0010] The lower base plate of the pipe support is welded to the concrete or steel structure pier embedded parts to form an integral body with the concrete or steel structure bracket. A plurality of round steels are welded to the upper part of the lower base plate of the pipe support, and a corresponding number of holes are arranged on the polytetrafluoroethylene plate to connect with the lower base plate, thereby preventing the polytetrafluoroethylene plate from falling off during the sliding of the bracket during the operation of the steam pipeline. The utility model helps to stabilize the drag reduction surface of the bracket, and avoid changes in the contact surface of the bracket due to the falling of the polytetrafluoroethylene plate, which in turn leads to increased friction and heat dissipation, affecting the safe operation of the steam pipeline.
[0011] The utility model is used for the plane sliding bracket for laying overhead steam pipelines. By optimizing the connection form between the heat-insulating pipe clamp and the steam pipeline, the phenomenon that the heat-insulating pipe clamp and the steam pipeline are relatively displaced due to thermal expansion and contraction during the operation of the steam pipeline network, thereby causing the sliding bracket to slide off the concrete pier, is avoided. In addition, by optimizing the fixing method of the polytetrafluoroethylene heat-insulating drag-reducing block and the embedded parts of the concrete pier, the phenomenon that the contact surface of the bracket changes due to the falling of the polytetrafluoroethylene heat-insulating drag-reducing block, thereby causing the stress of the civil engineering bracket to increase, is avoided. The utility model bracket helps to improve the safety and reliability of the operation of the pipe steam network, has stronger operability when laying multiple pipes side by side, and is more convenient to use.
