Description

Technical Field

[0001] The utility model relates to the technical field of expansion joint processing, in particular to an expansion joint positioning support frame. Background Art

[0002] An expansion joint is a device used to compensate for deformation of pipelines, containers or equipment caused by temperature changes, vibrations, displacements and other factors. It can effectively solve the pipeline stress and deformation problems caused by temperature changes and protect the pipeline system from damage. During the processing, the assembly of flanges and bellows requires repeated flipping and moving of the expansion joint for welding operations.

[0003] The existing patent number CN217452750U discloses an expansion joint positioning support frame, which includes two parallel and horizontally arranged channel steels, the width between adjacent channel steels is equal to the length of the expansion joint, the channel width of the channel steel is 3-5mm larger than the thickness of the flange of the expansion joint, the channel depth of the channel steel is equal to 1-1.5 times the minimum distance from the center of the threaded hole on the flange to the outer circumference of the flange, and after the two flanges of the expansion joint are inserted into the groove of the channel steel, the whole composed of the two flanges and the bellows can roll along the groove of the channel steel. When in use, since the channel steel is used to clamp the flange locally, the flange can be smoothly rolled along the groove of the channel steel, thereby eliminating the need for the welding operator to flip the expansion joint after each weld, and will not cause the direction of the expansion joint to change, which is convenient for operation. The structure of the utility model facilitates welding operators to weld while standing, making the welding operator more comfortable during operation and eliminating the problem of physical pain caused by squatting for a long time.

[0004] In the prior art, the distance between the horizontally arranged channel steel and the ground is fixed. During the processing, the height cannot be adjusted according to the usage. At the same time, due to the weight of the expansion joint, the expansion joint needs to be lifted during the loading and unloading process, which poses certain safety hazards. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] In view of the above problems existing in the existing expansion joint positioning support frame, the present utility model is proposed.

[0007] Therefore, the purpose of the present utility model is to provide an expansion joint positioning support frame, which is designed to solve the problem that "the distance between the horizontally arranged channel steel and the ground in the prior art is fixed, and the height cannot be adjusted according to the usage during the processing. At the same time, due to the weight of the expansion joint, the expansion joint needs to be lifted during the loading and unloading process of the expansion joint, which poses certain safety hazards."

[0031] The main unit 100 includes a base plate 101. Two sets of side fixing plates 102 are fixedly connected to the upper side surface of the base plate 101. One end of each side fixing plate 102 has a power compartment 103. The lower surface of the base plate 101 is mounted with four sets of brake wheels 105, allowing the base plate 101 to move flexibly.

[0032] The support unit 200 includes a motor 201 fixedly connected to the inner wall surface of the power compartment 103, and the output end shaft of the motor 201 is fixedly connected to a threaded rod 202, the surface of the threaded rod 202 is rotatably connected to the side fixing plate 102, the surface of the threaded rod 202 is threadedly connected to a threaded sleeve 203, and one side of the threaded sleeve 203 is fixedly connected to a bearing plate 204, the side surfaces of the two groups of side fixing plates 102 that are close to each other are movably connected to the bearing plate 204, and both ends of the two groups of bearing plates 204 are rotatably connected to a flap 207 to prevent the expansion joint from rolling out from the surface of the bearing plate 204, and a switch assembly 208 is provided on the opposite side of the flap 207.

[0033] Among them, both sets of switch components 208 include a fixed base 208a fixedly connected to the supporting plate 204, and the upper surface of the fixed base 208a is provided with a rotating groove. The interior of the two sets of rotating grooves is rotatably connected to a rotating rod 208b. The rotating rod 208b is manually pulled to flip inside the rotating groove, so that the rotating rod 208b is movably connected to the flip door 207, thereby being able to control the switch of the supporting plate 204.

[0034] Furthermore, the surfaces of the two sets of rotating rods 208b are fixedly connected with silicone sleeves 208c, and the surfaces of the silicone sleeves 208c are movably connected to the inner wall surface of the rotating groove, thereby increasing the rotational friction between the rotating rods 208b and the fixing base 208a.

[0038] During use, the expansion joint is rolled along the flap 207 to the surface of the supporting plate 204, and then the flap 207 is flipped upward to fit tightly with the supporting plate 204. Then the rotating rod 208b is manually pulled to flip inside the fixed seat 208a, so that the rotating rod 208b is movably connected to the flap 207, and the supporting plate 204 is closed. Then the motor 201 is turned on to drive the threaded rod 202 to rotate inside the side fixing plate 102, and the threaded sleeve 203 threadedly connected to the threaded rod 202 drives the fixedly connected supporting plate 204 to move upward to a specified height. At the same time, the sliding sleeve 205 fixedly connected to the supporting plate 204 slides upward on the surface of the sliding rod 206 to limit and support the supporting plate 204.
