Description

Technical Field

[0001] The utility model relates to the technical field of pipeline maintenance, in particular to an auxiliary supporting device for pipeline installation and maintenance. Background Art

[0002] Pipes are often used in water supply, drainage, heating and gas supply projects. At present, when installing or repairing pipelines, temporary masonry piers are mostly used to fix the pipelines on the piers, and then repair or decorate them. After the completion, they are dismantled and the piers are transported out as garbage. This practice is not recyclable and is not environmentally friendly. Therefore, in order to solve the above problems, as shown in patent application number 202021224990.4, an adjustable and movable temporary support for pipelines is proposed. The main structure consists of a movable support plate, a telescopic rod, a U-shaped support and an arc-shaped steel plate. When in use, first move the device to the bottom of the pipeline, and then adjust the telescopic rod to the appropriate height according to the height of the pipeline, and support the pipeline through the arc-shaped tray.

[0003] However, during use of the above-mentioned supporting device, since the size of the arc-shaped steel plate is fixed and cannot be adjusted according to the size of the pipeline, when encountering a pipeline with a larger diameter, since the spacing of the arc-shaped steel plates cannot be increased, the pipeline with a large diameter cannot be supported, resulting in poor practicality. When encountering a pipeline with a smaller diameter, since the spacing of the arc-shaped steel plates cannot be reduced, the spacing between the pipeline and the arc-shaped steel plate is too large, causing the pipeline to shake easily. Utility Model Content

[0004] The utility model aims to provide an auxiliary support device for pipeline installation and maintenance, so as to solve the problem that the existing support device cannot be adjusted according to the size of the pipeline, is easy to shake for pipelines with smaller diameters, and cannot support pipelines with larger diameters, resulting in poor practicality.

[0005] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: it includes an adjusting component, a telescopic mechanism and a movable frame, the two ends of the telescopic mechanism are respectively connected to the adjusting component and the movable frame, the adjusting component includes two arc-shaped trays and a fixed track, a bidirectional screw is rotated through the fixed track, one end of the bidirectional screw extends outside the fixed track, and a connecting block is provided at the bottom of each arc-shaped tray, and the two connecting blocks are threadedly connected to the bidirectional screw.

[0006] The working principle of the utility model is as follows: when it is necessary to install or overhaul a pipeline, first the device is pushed to the bottom of the pipeline through the mobile frame, and the screw is rotated according to the size of the pipeline. As the bidirectional screw rotates, the two arc trays on the bidirectional screw move so that the distance between the two arc trays can be inserted into the pipeline. Then the staff stands on the mobile frame and adjusts the length of the telescopic mechanism according to the height of the pipeline until the arc tray supports the pipeline. When the installation or overhaul of the pipeline is completed, the staff stands on the mobile frame, sinks the telescopic mechanism, and the pipeline can be moved out of the arc tray.

[0007] Beneficial effect: The arc tray is set to be adjustable, which is convenient for adjusting the arc tray according to the size of the pipeline, which is beneficial to stabilizing the pipeline, preventing the pipeline from falling off or being unable to support due to being too large or too small, and improving the practicality of the device.

[0018] Example 1

[0019] like Figures 1 to 3 As shown: an auxiliary support device for pipeline installation and maintenance, including an adjustment component 1, a telescopic mechanism 2 and a movable frame 3, the two ends of the telescopic mechanism 2 are respectively connected to the adjustment component 1 and the movable frame 3, the adjustment component 1 includes two arc-shaped trays 11 and a fixed track 12, a bidirectional screw 13 is rotatably penetrated in the fixed track 12, one end of the bidirectional screw 13 extends to the outside of the fixed track 12, and a knob 131 is provided at the end of the bidirectional screw 13 extending to the outside of the fixed track 12, and a connecting block 111 is provided at the bottom of each arc-shaped tray 11, and the two connecting blocks 111 are both threadedly connected to the bidirectional screw 13.

[0020] The telescopic mechanism 2 includes a screw 21 and a sleeve 22, a connecting ring 23 is fixedly connected to the sleeve 22, a bearing 24 is fixedly connected to the connecting ring 23, the bearing 24 is located directly above the sleeve, a nut 25 for threaded connection to the screw 21 is fixedly connected to the top of the inner ring of the bearing 24, and the end of the screw 21 away from the nut 25 is fixedly connected to the bottom of the fixed rail 12.

[0021] The mobile frame 3 includes a chassis 31, and four universal wheels 32 are provided at the bottom of the chassis 31. The end of the sleeve 22 away from the connecting ring 23 is fixedly connected to the chassis 31. A screw rod 33 is threadedly connected to the chassis 31. One end of the screw rod 33 located at the bottom of the chassis 31 is rotatably connected to a support plate 34, and a handle is provided on the screw rod 33.

[0022] The implementation method of this embodiment is as follows: when it is necessary to install or repair the pipeline, first push the device to the right below the pipeline through the universal wheel 32, then rotate the screw rod 33 to move the screw rod 33 downward, and as the screw rod 33 moves, the support plate 34 slowly contacts the ground. When the universal wheel is lifted and suspended in the air, the knob 131 is manually rotated according to the size of the pipeline, and the knob 131 drives the bidirectional screw rod 13 to rotate. As the bidirectional screw rod 13 rotates, the two arc trays 11 on the bidirectional screw rod 13 move, so that the distance between the two arc trays 11 can be stuck into the pipeline, and then the staff stands on the chassis 31, Hold the lead screw 21 with one hand and then use a wrench to turn the nut 25. As the nut 25 turns, the end of the lead screw 21 located in the sleeve 22 slowly rises until the arc-shaped tray 11 supports the pipeline; when the pipeline is installed or repaired, the staff stands on the chassis 31, holds the lead screw with one hand, and then uses a wrench to turn the nut 25 in the opposite direction. As the nut 25 turns, the lead screw 21 slowly extends into the sleeve 22. After the pipeline is moved out of the arc-shaped tray 11, the screw 33 is rotated in the opposite direction to move the screw 33 upward. As the screw 33 moves, the support plate 34 leaves the ground and the universal wheel 32 contacts the ground.
