Description

Technical Field

[0001] This utility model relates to the field of pipeline support technology, specifically an adjustable large-diameter pipe support structure. Background Technology

[0002] Pipeline support refers to various structures or devices used in pipeline systems to fix, support, and protect pipelines, ensuring their stability, safety, and normal function under various operating conditions (such as normal operation, temperature changes, pressure fluctuations, earthquakes, etc.). Pipeline support is fundamental to the safe operation of pipeline systems and requires comprehensive design based on pipeline operating conditions, media characteristics, and environmental conditions. Appropriate support can not only extend pipeline life but also reduce maintenance costs and ensure production safety.

[0003] However, in practical applications, supporting large-diameter pipes is a critical issue during building construction and pipeline laying. Traditional support methods have many drawbacks, such as the relatively fixed support rod structure, which makes it difficult to adapt to the support requirements of different diameters and spatial heights, thus making it difficult to adapt to pipeline laying under complex working conditions. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable large-diameter pipe support structure to address the critical issue of supporting large-diameter pipes during building construction and pipeline laying, as mentioned in the background section. Traditional support methods have many drawbacks, such as relatively fixed support rod structures that are difficult to adapt to the support requirements of different diameters and spatial heights, thus making it difficult to address pipeline laying problems under complex working conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a movable base, a U-shaped support seat fixedly installed on the upper end of the movable base, a first drive motor fixedly installed at the bottom of the U-shaped support seat, a first transmission gear fixedly installed on the upper transmission shaft portion of the first drive motor, a second transmission gear meshing with the side end of the first transmission gear, an internally threaded transmission tube fixedly installed in the middle of the second transmission gear, a lifting screw threadedly connected to the inner wall of the internally threaded transmission tube, a lifting platform fixedly installed at the top end of the lifting screw, a vertical limiting slide rail fixedly installed on the inner side wall of the U-shaped support seat, a second drive motor fixedly installed on the outer side of the upper end of the lifting platform, a transmission screw fixedly installed on the inner transmission shaft portion of the second drive motor, a movable platform threadedly connected to the outer curved surfaces at both ends of the transmission screw, a horizontal limiting slide rail fixedly installed on the upper end of the lifting platform, and a scissor-type support frame rotatably connected to the outer side of the movable platform via a pin shaft, with a support roller fixedly installed at the upper end of the scissor-type support frame for supporting the tube body.

[0006] Preferably, the bottom of the movable base is fixedly equipped with a number of support rollers, which are symmetrically distributed around the bottom of the movable base. The support rollers are composed of lockable rollers.

[0007] Preferably, a power control box is fixedly installed on the outside of the mobile base, and a mobile control power supply is fixedly installed inside the power control box.

[0008] Preferably, the internal threaded transmission tube is rotatably connected to the lower middle part of the U-shaped support through a rotating shaft, and there are four vertical limiting slide rails, which are symmetrically distributed on the inner sidewall of the U-shaped support. The outer end of the lifting platform is movably connected to the inner side of the vertical limiting slide rail.

[0009] Preferably, the first drive motor and the second drive motor are lockable motors, and the outer curved threads at both ends of the transmission screw face opposite directions.

[0010] Preferably, there are two movable stages, which are symmetrically distributed at both ends of the transmission screw, and the movable stages are movably connected to the upper end of the horizontal limiting slide rail.

[0011] Preferably, the scissor support frame consists of a main support frame and a secondary support frame, which are connected to each other by a pivot pin at their midpoints, and the outer curved surface of the support roller is provided with anti-slip stripes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When the first drive motor is turned on, it drives the first transmission gear to rotate. When the first transmission gear rotates, it meshes with and drives the second transmission gear to rotate. When the second transmission gear rotates, it drives the internal thread transmission tube to rotate. When the internal thread transmission tube rotates, the force generated by the threaded connection drives the lifting screw to move up and down. When the lifting screw moves up and down, it drives the lifting platform to move up and down linearly. When the lifting platform moves up and down linearly, it synchronously drives the support roller to move up and down linearly to adjust the support height.

[0014] This invention also features a second drive motor that, when activated, drives a transmission screw to rotate. The threads on the outer curved surfaces of the two ends of the transmission screw face opposite directions. This rotation of the transmission screw, due to the force generated by the threaded connection, causes the moving platform to move synchronously inward or outward in a straight line. This inward or outward movement of the moving platform, in turn, causes the lower end of the scissor support frame to move synchronously inward or outward in a straight line. This inward or outward movement of the lower end of the scissor support frame causes the entire scissor support frame to move in a cross motion. This cross motion of the entire scissor support frame causes the support rollers to contract or expand synchronously, adjusting the support distance. This allows for the support of pipes of different diameters, thus enabling simultaneous support of the pipe and easy adjustment of the support height and support distance.

[0020] Please see Figure 1-3This utility model provides an adjustable large-diameter pipe support structure technical solution: including a movable base 1, with a number of support rollers 2 fixedly installed at the bottom of the movable base 1, and the support rollers 2 are symmetrically distributed at the bottom of the movable base 1. The support rollers 2 are composed of lockable rollers, so that the movable base 1 can be locked and fixed at the same time as being supported by the support rollers 2. A power control box 3 is fixedly installed on the outside of the movable base 1, and a movable control power supply is fixedly installed inside the power control box 3.

[0021] A U-shaped support base 4 is fixedly installed on the upper end of the mobile base 1. A first drive motor 5 is fixedly installed on the bottom of the U-shaped support base 4. A first transmission gear 6 is fixedly installed on the upper drive shaft of the first drive motor 5. A second transmission gear 7 is meshed with the side end of the first transmission gear 6. An internally threaded transmission tube 8 is fixedly installed in the middle of the second transmission gear 7. The internally threaded transmission tube 8 is rotatably connected to the lower middle of the U-shaped support base 4 through a rotating shaft. A lifting screw 9 is threadedly connected to the inner wall of the internally threaded transmission tube 8. A lifting platform 10 is fixedly installed on the top end of the lifting screw 9. A vertical limiting slide rail 11 is fixedly installed on the inner side wall of the U-shaped support base 4. There are four vertical limiting slide rails 11, which are symmetrically distributed on the inner side wall of the U-shaped support base 4. The outer end of the lifting platform 10 is movably connected to the inner side of the vertical limiting slide rail 11, so that the lifting platform 10 can be linearly limited by the vertical limiting slide rail 11. A second drive motor 1 is fixedly installed on the outer side of the upper end of the lifting platform 10. 2. The first drive motor 5 and the second drive motor 12 are lockable motors. The transmission shaft of the second drive motor 12 is fixedly installed with a transmission screw 13. The outer curved threads at both ends of the transmission screw 13 face opposite directions. The outer curved threads at both ends of the transmission screw 13 are connected to a moving platform 14. There are two moving platforms 14, which are symmetrically distributed at both ends of the transmission screw 13. A horizontal limiting slide rail 15 is fixedly installed on the upper end of the lifting platform 10. The moving platform 14 is movably connected to the upper end of the horizontal limiting slide rail 15, so that the moving platform 14 can be linearly limited by the horizontal limiting slide rail 15. A scissor support frame 16 is rotatably connected to the outside of the moving platform 14 by a pin. The scissor support frame 16 is composed of a main support frame and a secondary support frame. The main support frame and the secondary support frame are rotatably connected to each other by a pin. A support roller 17 for supporting the tube is fixedly installed on the upper end of the scissor support frame 16. The outer curved surface of the support roller 17 is provided with anti-slip stripes.

[0022] Working principle: In use, this utility model controls the activation of the first drive motor 5. When the first drive motor 5 is activated, it drives the first transmission gear 6 to rotate. When the first transmission gear 6 rotates, it meshes with and drives the second transmission gear 7 to rotate. When the second transmission gear 7 rotates, it drives the internal thread transmission tube 8 to rotate. When the internal thread transmission tube 8 rotates, the force generated by the threaded connection drives the lifting screw 9 to move up and down. When the lifting screw 9 moves up and down, it drives the lifting platform 10 to move up and down linearly. When the lifting platform 10 moves up and down linearly, it synchronously drives the support roller 17 to move up and down linearly to adjust the support height.

[0023] By controlling the activation of the second drive motor 12, when the second drive motor 12 is activated, it drives the transmission screw 13 to rotate. The outer curved threads at both ends of the transmission screw 13 face opposite directions. When the transmission screw 13 rotates, the force generated by the threaded connection drives the moving table 14 to move inward or outward in a straight line synchronously. When the moving table 14 moves inward or outward in a straight line synchronously, it drives the lower end of the scissor support frame 16 to move inward or outward in a straight line synchronously. When the lower end of the scissor support frame 16 moves inward or outward in a straight line synchronously, it drives the entire scissor support frame 16 to perform cross-movement. When the entire scissor support frame 16 performs cross-movement, it drives the support roller 17 to contract or expand synchronously to adjust the support distance, so as to support pipes of different diameters. This allows for the support of the pipe while facilitating the adjustment of the support height and support distance.
