Description

Technical Field

[0001] The utility model relates to the technical field of maintenance racks, in particular to a pipeline maintenance rack. Background Art

[0002] A pipe access rack, also known as a pipe support or pipe bracket, is a device used to support and fix pipes. Its main function is to ensure the stability and safety of pipes in various industrial and commercial environments, such as petroleum, chemical, electric power, heat, water and other industries. The design and structure of pipe access racks vary depending on the type, size, weight, working environment and required functions of the pipes. Generally speaking, they are made of steel, stainless steel or other corrosion-resistant materials to ensure that their structural integrity and functionality can be maintained under various environmental conditions.

[0003] For example, the Chinese authorized patent "A Pipeline Maintenance Frame" with announcement number CN207814748U includes a load-bearing plate, a fixing plate welded on the upper surface of the load-bearing plate, the fixing plate is trapezoidal, and a lower support plate is welded on the upper part, and a protective rubber pad is fixed to the lower end of the inner surface of the lower support plate by glue, and spring hinges are symmetrically provided on the left and right sides of the protective rubber pad, and the spring hinges are fixed on the inner surface of the lower support plate, and a connecting shaft is provided at the upper end of the connecting rod, and rotating wheels are placed on both sides of the pipeline, and the upper support plate is installed on the hinge, and a threaded cavity is opened in the middle of the upper support plate, and the main tightening rod is screwed into the threaded cavity, and a tightening nut is provided at the upper end of the main tightening rod, and a clamping block is fixed below the connecting block, and the clamping block is placed above the pipeline, and the auxiliary tightening rod is installed in the upper support plate.

[0004] Although the above-mentioned existing technology can support the pipeline, it is applied in different scenarios. Due to the relatively simple overall adjustment structure, the angle and height of the pipeline cannot be flexibly adjusted during the maintenance process, and therefore does not meet the existing needs. In this regard, we propose a pipeline maintenance rack. Utility Model Content

[0005] The utility model aims to provide a pipeline maintenance rack to solve the problem that the maintenance rack proposed in the above background technology cannot flexibly adjust the angle and height of the pipeline during the maintenance process.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a pipeline maintenance frame, comprising a base, an angle adjustment platform is arranged above the base, a support platform is arranged above the angle adjustment platform, pipeline clamping frames are arranged on both sides of the upper end surface of the support platform, clamping mechanisms are arranged at the front and rear upper ends of the pipeline clamping frames, the inner cavity of the clamping mechanism passes through the inner wall of the pipeline clamping frame, and the clamping mechanism is welded and fixed to the pipeline clamping frame, a clamping block is installed inside the clamping mechanism, and the clamping block and the inner cavity of the clamping mechanism are slidably limited, a threaded hole is arranged inside the clamping block, a first adjusting wheel is installed on the outer side of the clamping mechanism, and the first adjusting wheel is rotatably connected to the clamping mechanism, a stud is fixedly installed on the shaft at one end of the inner side of the first adjusting wheel, the stud extends to the inside of the clamping block, and the stud is adapted to the clamping block.

[0007] Preferably, support frames are provided on both sides of the angle adjustment platform, and the bottom of the support frame is welded and fixed to the base, a connecting shaft is fixedly provided at the middle position of the side wall of the angle adjustment platform, the connecting shaft extends to the interior of the support frame, and the connecting shaft is rotatably connected to the support frame, a worm gear is fixedly provided at one end of the connecting shaft located inside the support frame, a worm is installed below the worm gear, the worm gear is rotatably connected to the support frame, and the external thread of the worm gear is adapted to the worm wheel, a second adjusting wheel is rotatably installed at the front end of the support frame, and the shaft at the rear end of the second adjusting wheel is fixed to the worm gear.

[0008] Preferably, a rubber block is provided at one end of the clamping block close to the pipe, and the rubber block is adhered and fixed to the clamping block.

[0009] Preferably, an electric push rod is symmetrically installed between the angle adjustment platform and the support platform, the fixed end of the electric push rod is fixed to the angle adjustment platform by bolts, and the movable end of the electric push rod is fixed to the support platform by bolts.

[0010] Preferably, a fixing seat is welded between the pipe clamping frame and the supporting platform.

[0011] Preferably, universal locking wheels are installed at the four corners of the bottom of the base.

[0012] Preferably, a tool box is fixedly mounted at a middle position of the upper end surface of the base.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a flexible pipe clamping mechanism. When inspecting the pipe, the pipe clamping frame is moved to the bottom of the target pipe through the universal locking wheel, and then the electric push rod is turned on to drive the pipe clamping frame to rise until the bottom of its inner wall contacts the pipe. Then the staff can turn the first adjusting wheel to drive the stud at one end to rotate. Under the friction between the stud and the internal threaded hole of the clamping block, the inner cavity of the clamping mechanism guides the clamping block, so that the clamping block moves toward the direction of the pipe until it is clamped and fixed. At the same time, a rubber block is adhered to the outside of the clamping block. The rubber block can not only improve the fastening effect with the pipe through its own elasticity, but also avoid hard friction between the fastening block and the pipe to cause damage to each other. The structure can be flexibly fixed according to the diameter specification of the pipe, which is not only convenient to operate, but also effectively improves the overall stability.

[0015] 2. The utility model is provided with an angle adjustment platform. When the angle of the pipeline needs to be adjusted before installation or after disassembly, the staff can manually turn the second adjusting wheel, and one end of the second adjusting wheel will drive the worm to rotate. The contact surface between the worm and the worm wheel forms a spiral friction transmission surface, and the rotation of the worm drives the worm wheel to rotate, and then the angle adjustment platform is driven by the shaft at one end of the worm wheel to adjust the angle, thereby realizing the inclination of the pipeline angle. During this process, the angle adjustment platform can be smoothly and accurately adjusted to the required angle to ensure that the inclination angle of the pipeline meets the working requirements. At the same time, the self-locking property of the worm gear can be used to ensure that the adjusted angle adjustment platform remains fixed in this position. Therefore, the pipeline maintenance rack can realize fast, accurate and stable pipeline angle adjustment, which greatly improves the efficiency and safety of pipeline installation and maintenance.
