Description
Technical Field
[0001] This utility model belongs to the field of pipeline maintenance technology, and in particular relates to a support device for pipeline maintenance. Background Technology
[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. When a pipeline is damaged, support devices are needed to reinforce and strengthen it during maintenance and repair.
[0003] Chinese utility model patent CN221922280U discloses a pipe support device for water supply and drainage maintenance. The device is moved to the bottom of the water supply and drainage pipe by casters. The motor works, and the first bevel gear at the output end of the motor drives the lead screw to rotate through the second bevel gear. The lead screw drives the base plate to move through the lead screw sleeve. The base plate pushes the top seat to move through the support rod and the cross plate. The inner wall of the arc groove opened on the top seat fits tightly with the pipe. The movable end of the electric cylinder works and pushes the baffle to rotate. The baffles on both sides of the pipe restrict the pipe and prevent the pipe from rolling on the support device during maintenance.
[0004] Based on research and practical experience in pipeline maintenance and support, it was found that the aforementioned devices offer limited support points for pipelines, hindering the provision of broader and more effective support, and also exhibiting instability in the clamping of the pipeline. Therefore, there is an urgent need to improve existing pipeline maintenance support devices and provide a new type of pipeline maintenance support device. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a pipeline maintenance support device that is reasonably designed, simple in structure, has better support and reinforcement effect, and facilitates stable clamping and positioning of pipelines, thereby solving the problems existing in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A support device for pipeline maintenance includes a base, with support leg assemblies at the bottom of each of the four right angles of the base. A first horizontal shaft and a second horizontal shaft are symmetrically connected by bearings inside the base. First support rods are fixed to both ends of the first horizontal shaft, and second support rods are fixed to both ends of the second horizontal shaft. The first and second support rods on the same side are of equal length and horizontal to each other. Gear plates are fixed to the outer walls of the two second support rods on the side where their bottom ends are close together, and the two gear plates mesh with each other. An adjustment assembly for controlling the rotation of the second horizontal shaft is installed inside the left end of the base. The top ends of the first and second support rods are hinged to a lower support. Fixed studs are symmetrically fixed above the front and rear ends of the lower support. An upper support is located directly above the lower support.
[0008] In a preferred embodiment, the support leg assembly includes a fixing block, a splicing column, and a base. The fixing block is fixedly installed on the bottom surface of the base, and a splicing column is installed between the fixing block and the base. The number of splicing columns is at least one.
[0009] In a preferred embodiment, a locking block is fixed at the center of the bottom end of both the fixing block and the splicing column, and the locking block has a through hole structure inside. A slot is formed at the center of the top end of both the splicing column and the base, and the slot is adapted to the locking block.
[0010] In a preferred embodiment, both the top outer surfaces of the splicing column and the base are threaded with a first bolt, which is adapted to the internal through-hole structure of the locking block.
[0011] In a preferred embodiment, the adjusting assembly includes a worm gear, a worm, and a second bolt. The worm gear is fixedly installed on the outer side of the middle of the second horizontal shaft, the worm bearing is installed on the inner side of the top of the base, and a second bolt for positioning the worm by contact is threaded onto the upper left of the base.
[0012] In a preferred embodiment, the worm gear is located directly below the spiral portion of the worm and the two mesh with each other.
[0013] In a preferred embodiment, both the lower and upper supports have a "V"-shaped groove at the center of their adjacent sides. The front and rear ends of the upper support are slidably fitted onto the outer sides of two fixing studs, and nuts are threaded onto the outer sides of the fixing studs, above the upper support. Compared with the prior art, the advantages of this utility model are:
[0014] In the solution of this utility model:
[0015] By manually rotating the worm gear, the worm wheel can be driven to rotate the second horizontal shaft and the second support rod. Under the action of the two meshing gear discs, the left and right second support rods can be controlled to rotate synchronously in opposite directions. With the support and cooperation of the first support rod, the left and right lower supports can be easily controlled to move in a stable horizontal posture. The distance between the two lower supports can be adjusted, which is convenient to adjust the support range according to the actual needs of pipeline maintenance, so as to realize multi-point support of the pipeline and better pipeline support effect.
[0016] The device utilizes "V"-shaped grooves on both the lower and upper supports that are close to each other to securely clamp pipes of different diameters. Furthermore, the number of splicing columns can be flexibly increased or decreased during actual installation and use, facilitating convenient height adjustment and providing stable support for pipes at different heights.

Detailed Implementation
[0025] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:
[0026] like Figure 1-5 As shown, the pipeline maintenance support device of this utility model includes a base 1. Support leg assemblies 2 are provided at the bottom of the four right angles of the base 1. The base 1 is symmetrically connected to the first horizontal shaft 3 and the second horizontal shaft 5 by bearings. The first support rod 4 is fixed at both the front and rear ends of the first horizontal shaft 3. The second support rod 6 is fixed at both the front and rear ends of the second horizontal shaft 5. The first support rod 4 and the second support rod 6 on the same side are of equal length and are in a horizontal state. The outer wall of the side where the bottom ends of the two second support rods 6 are close together is fixed with a toothed disc 7. The two toothed discs 7 mesh with each other. An adjustment assembly 8 for controlling the rotation of the second horizontal shaft 5 is installed inside the left end of the base 1. The top ends of the first support rod 4 and the second support rod 6 are hinged to the lower support 9. Fixing studs 10 are symmetrically fixed above the front and rear ends of the lower support 9. An upper support 11 is provided directly above the lower support 9.
[0027] Based on the above structure, the support leg assembly 2 includes a fixing block 21, a splicing column 22 and a base 23. The fixing block 21 is fixedly installed on the bottom end face of the base 1. The splicing column 22 is installed between the fixing block 21 and the base 23. The number of splicing columns 22 is at least one.
[0028] Based on the above structure, a locking block 24 is fixed at the bottom center of both the fixing block 21 and the splicing column 22. The locking block 24 has a through hole structure inside. A slot 25 is opened at the top center of both the splicing column 22 and the base 23. The slot 25 is adapted to the locking block 24.
[0029] In this embodiment, the card block 24 and card slot 25 are used to facilitate quick connection between the fixing block 21, splicing column 22 and base 23. Moreover, the number of splicing columns 22 can be increased or decreased according to the actual situation, which facilitates convenient adjustment of the height of the device.
[0030] Based on the above structure, the top outer surfaces of both the splicing column 22 and the base 23 are threaded with a first bolt 26, which is compatible with the internal through hole structure of the locking block 24.
[0031] In this embodiment, by tightening the first bolt 26, one end of it is inserted into the through hole structure inside the corresponding locking block 24, which facilitates the stable splicing and installation between the fixing block 21, the splicing column 22 and the base 23.
[0032] Based on the above structure, the adjusting assembly 8 includes a worm gear 81, a worm 82, and a second bolt 83. The worm gear 81 is fixedly installed on the outer side of the middle part of the second horizontal shaft 5, and the worm 82 is bearing installed on the inner side of the top of the base 1. The second bolt 83 for positioning the worm 82 by contact is threaded on the upper left side of the base 1.
[0033] In this embodiment, tightening the second bolt 83 facilitates the positioning of the worm gear 82, preventing accidental rotation of the worm gear 82 from affecting the stability of the device's support for the pipeline.
[0034] Based on the above structure, the worm gear 81 is located directly below the worm section of the worm 82 and the two mesh with each other.
[0035] In this embodiment, by controlling the rotation of the worm gear 82, it is easy to control the worm wheel 81 to drive the second horizontal shaft 5 to rotate, thereby facilitating the control of the rotation adjustment of the first support rod 4 and the second support rod 6.
[0036] Based on the above structure, a "V" shaped groove is provided in the middle of the side of the lower support 9 and the upper support 11 that are close to each other. The front and rear ends of the upper support 11 are respectively slidably sleeved on the outside of the two fixing studs 10. A nut 12 is threadedly sleeved on the outside of the fixing studs 10 and above the upper support 11.
[0037] In this embodiment, the "V"-shaped grooves on both the lower support 9 and the upper support 11, which are close to each other, facilitate the stable clamping of pipes of different diameters.
[0038] The working principle of this utility model is as follows:
[0039] When in use, first install an appropriate number of splicing columns 22, and tighten the first bolt 26 so that one end of it is inserted into the through hole structure inside the corresponding clip 24, which facilitates the stable splicing installation between the fixing block 21, splicing column 22 and base 23. The number of splicing columns 22 can be flexibly increased or decreased, which facilitates the convenient adjustment of the height of the device and provides stable support for pipes at different heights.
[0040] The device is then placed under the pipe to be supported, with the first support rod 4 and the second support rod 6 in a horizontal position. The worm gear 82 is then manually rotated, which drives the second horizontal shaft 5 and the second support rod 6 to rotate via the worm wheel 81. Under the action of the two meshing gear discs 7, the left and right second support rods 6 can be controlled to rotate synchronously in a direction that approaches each other. With the support and cooperation of the first support rod 4, the left and right lower supports 9 can be easily controlled to rise in a stable horizontal position until the lower supports 9 are in contact with the bottom outer wall of the pipe. The two lower supports 9 can achieve multi-point support for the pipe, making the support more stable and effective. Then, the upper support 11 is fitted onto the outside of the fixing stud 10 and moved down, and the nut 12 is tightened. The "V"-shaped grooves on the side of the lower support 9 and the upper support 11 that are close to each other are used to securely clamp pipes of different diameters. The worm gear 82 can also be positioned by tightening the second bolt 83.
[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
