Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a water conservancy construction pipeline positioning device. Background Technology

[0002] Water conservancy pipelines are an important component of modern water conservancy infrastructure, mainly used for the transportation, distribution, regulation and discharge of water resources. These pipeline systems are usually made of high-strength materials and are designed with different diameters, pressure ratings and corrosion resistance performance according to project requirements. When laying pipelines, positioning devices are needed to determine the pipeline laying location.

[0003] Most current pipe positioning devices have relatively simple structures. When positioning the pipe laying position, they often directly clamp the outside of the pipe. When the pipe is long, the clamping position of the device may be offset from the middle of the pipe, causing the center of gravity at both ends of the pipe to be unstable. The pipe is prone to shaking when moving, which affects the quick and accurate positioning of the pipe laying position.

[0004] Therefore, in view of the fact that the clamping center of gravity of existing pipeline positioning devices is prone to shift and wobbling during movement, a new pipeline positioning device for water conservancy construction can be designed. By extending the fixing method, the clamping center of gravity is ensured to be stable according to the pipeline length, improving the stability of the pipeline during movement, ensuring rapid and accurate positioning of the pipeline laying position, thereby effectively enhancing the practical value of the device. Utility Model Content

[0005] To overcome the problem that most pipe positioning devices may shift the clamping position to the middle position when the pipe is long, causing instability at both ends of the pipe and making the pipe sway easily during movement, thus affecting the rapid and accurate positioning of the pipe laying position, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: a positioning device for a water conservancy construction pipeline, comprising a base, universal stop wheels, a first hydraulic rod, a top plate, a bidirectional screw rod, a control component, a first clamping plate, a first support plate, a pressing component, a third hydraulic rod, a second clamping plate, a second support plate, and a fixing component. Two sets of universal stop wheels are symmetrically arranged on the bottom surfaces of both ends of the base. A first hydraulic rod is arranged at the center of the top of the base. A top plate is arranged at the outer telescopic end of the first hydraulic rod. A bidirectional screw rod is arranged on the inner side of the bottom end of the top plate. A control component is arranged on one side of the top plate. A first clamping plate is arranged on the outer side of the bidirectional screw rod. A first support plate is arranged on the inner side of the bottom end of the first clamping plate. A pressing component is arranged at the bottom end of the top plate. Two sets of third hydraulic rods are symmetrically arranged on the outer side of the bottom end of the first clamping plate. A second clamping plate is arranged at the outer telescopic end of the third hydraulic rod. A second support plate is arranged on the inner side of the bottom end of the second clamping plate. A fixing component is arranged on the outer side of the bottom end of the first clamping plate.

[0007] Preferably, a double-acting screw is fixed to the top plate, and the operation of each structure of the device is controlled by the control component. Rotating the double-acting screw flexibly adjusts the distance between the two sets of first clamping plates. The first clamping plates clamp and fix the pipe according to the actual diameter of the pipe. The first support plate supports the pipe channel, and the pressing component presses and fixes the pipe from top to bottom, initially fixing the pipe position in the device. The third hydraulic rod is extended and retracted according to the actual length of the pipe. The position of the third hydraulic rod is fixed to the first clamping plate by the fixing component. The extension and retraction of the third hydraulic rod adjusts the position of the second clamping plate, moving the second clamping plate to both ends of the pipe. The second clamping plate clamps the outer sides of both ends of the pipe. The second support plate supports both ends of the pipe channel, ensuring the pipe is placed in a balanced position. Rotating the universal stop wheel flexibly moves the position of the base, and simultaneously extending and retracting the first hydraulic rod adjusts the height of the top plate, moving the pipe to the designated laying height. This achieves the effect of ensuring the stability of the clamping center of gravity according to the pipe length, improving the stability of the pipe during movement, ensuring the effect of quickly and accurately positioning the pipe laying position, and enhancing the practical value of the device.

[0008] Preferably, the base is symmetrically arranged with two sets of bidirectional lead screws rotatably connected to the top plate, the top of the first clamping plate is threadedly connected to the bidirectional lead screws, the distance between the two sets of second clamping plates is the same as the distance between the two sets of first clamping plates, and the second support plate is at the same horizontal height as the first support plate.

[0009] Preferably, the control components include a console and a servo motor, wherein the console is located on one side of the top of a set of bases, and the servo motor is located on one side of the outer side of the top plate.

[0010] Preferably, the control console is electrically connected to the first hydraulic rod and the third hydraulic rod, the output end of the servo motor is connected to the bidirectional lead screw, and the servo motor is electrically connected to the control console.

[0011] Preferably, the pressing assembly includes a second hydraulic rod and a pressure plate, with the second hydraulic rod located at the bottom end of the top plate and the pressure plate located at the outer telescopic end of the second hydraulic rod.

[0012] Preferably, the second hydraulic rod is located at the center of the bottom end of the top plate, and the second hydraulic rod is electrically connected to the control console.

[0013] Preferably, the fixing assembly includes a fixing plate and a connecting plate. The fixing plate is provided on the outer side of the bottom end of the first clamping plate, the third hydraulic rod is symmetrically arranged on both sides of the fixing plate, the outer telescopic end of the third hydraulic rod is provided with a connecting plate, and the second clamping plate is provided on one outer end of the connecting plate.

[0014] The beneficial effects of this utility model are:

[0015] During pipeline laying, the third hydraulic rod is extended or retracted according to the actual length of the pipeline. This extension or retraction adjusts the position of the second clamping plate, moving it to both ends of the pipeline. A double-acting screw is fixed to the top plate, and the distance between the two sets of first clamping plates is flexibly adjusted by rotating the screw. The first clamping plates clamp and fix the pipeline according to its actual diameter. The first support plate supports the pipeline, simultaneously causing the second clamping plate to clamp the outer sides of both ends of the pipeline. The second support plate supports both ends of the pipeline, ensuring balanced placement. The universal stop wheels are rotated to flexibly move the base position, and the first hydraulic rod is extended or retracted simultaneously to adjust the height of the top plate, moving the pipeline to the designated laying height. This addresses the problem that with most pipeline positioning devices, when the pipeline length is long, the clamping position may deviate from the middle of the pipeline, causing instability at both ends and easy swaying during movement, affecting the rapid and accurate positioning of the pipeline. This enhances the practical value of the device. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 2This utility model provides an embodiment: a positioning device for a water conservancy construction pipeline, including a base 1, universal stop wheels 2, a first hydraulic rod 3, a top plate 4, a bidirectional screw rod 5, a control component, a first clamping plate 6, a first support plate 7, a pressing component, a third hydraulic rod 8, a second clamping plate 9, a second support plate 10, and a fixing component. Two sets of universal stop wheels 2 are symmetrically arranged on the base 1. Two sets of universal stop wheels 2 are symmetrically arranged on the bottom surfaces of both ends of the base 1. A first hydraulic rod 3 is arranged at the center of the top of the base 1. A top plate 4 is arranged at the outer telescopic end of the first hydraulic rod 3. A bidirectional screw rod 5 is arranged on the inner side of the bottom end of the top plate 4. The bidirectional screw rod 5 is rotatably connected to the top plate 4. A control component is provided on one side of the top plate 4. A first clamping plate 6 is provided on the outer side of the double-acting screw 5. The top of the first clamping plate 6 is threadedly connected to the double-acting screw 5. A first support plate 7 is provided on the inner side of the bottom end of the first clamping plate 6. A pressing component is provided on the bottom end of the top plate 4. Two sets of third hydraulic rods 8 are symmetrically arranged on the outer side of the bottom end of the first clamping plate 6. A second clamping plate 9 is provided on the telescopic end of the outer side of the third hydraulic rod 8. The distance between the two sets of second clamping plates 9 is the same as the distance between the two sets of first clamping plates 6. A second support plate 10 is provided on the inner side of the bottom end of the second clamping plate 9. The second support plate 10 is at the same horizontal height as the first support plate 7. A fixing component is provided on the outer side of the bottom end of the first clamping plate 6.

[0023] Please see Figure 1 and Figure 3 In this embodiment, the control component includes a control console 301 and a servo motor 501. The control console 301 is provided on one side of the top of a set of bases 1. The control console 301 is electrically connected to the first hydraulic rod 3 and the third hydraulic rod 8. The servo motor 501 is provided on one side of the outer side of the top plate 4. The output end of the servo motor 501 is connected to the bidirectional lead screw 5. The servo motor 501 is electrically connected to the control console 301. The control console 301 sends extension and retraction commands to the first hydraulic rod 3 and the third hydraulic rod 8. The extension and retraction of the first hydraulic rod 3 adjusts the placement height of the top plate 4, and the extension and retraction of the third hydraulic rod 8 adjusts the position of the second clamping plate 9. The control console 301 sends a running command to the servo motor 501, which drives the bidirectional lead screw 5 to rotate. The bidirectional lead screw 5 is rotated according to the actual outer diameter of the pipe to adjust the distance between the two sets of first clamping plates 6, so that the first clamping plates 6 clamp the middle of the pipe.

[0024] The pressing assembly includes a second hydraulic rod 701 and a pressure plate 702. The second hydraulic rod 701 is located at the bottom end of the top plate 4 and is positioned in the middle of the bottom end of the top plate 4. The second hydraulic rod 701 is electrically connected to the control console 301. The pressure plate 702 is located at the outer telescopic end of the second hydraulic rod 701. The control console 301 sends a telescopic command to the second hydraulic rod 701 to adjust the height of the pressure plate 702. The pressure plate 702 is used to press the pipe, so that the pressure plate 702 and the first support plate 7 clamp and fix the pipe from another direction.

[0025] Please see Figure 4 In this embodiment, the fixing component includes a fixing plate 801 and a connecting plate 802. The fixing plate 801 is provided on the outer side of the bottom end of the first clamping plate 6. The third hydraulic rod 8 is symmetrically arranged on both sides of the fixing plate 801. The connecting plate 802 is provided on the outer telescopic end of the third hydraulic rod 8. The second clamping plate 9 is provided on one outer end of the connecting plate 802. The position of the third hydraulic rod 8 is fixed by the fixing plate 801, and the position of the second clamping plate 9 is fixed by the connecting plate 802, ensuring that the position of the second clamping plate 9 corresponds to the position of the first clamping plate 6.

[0026] When fixing the pipeline, the top plate 4 is located above the middle of the pipeline. The control console 301 sends a retraction command to the first hydraulic rod 3, which retracts the first hydraulic rod 3 to lower the height of the top plate 4. According to the length of the pipeline, the control console 301 controls all the third hydraulic rods 8 to extend synchronously. The extension of the third hydraulic rods 8 moves the second clamping plate 9 to both ends of the pipeline.

[0027] Subsequently, the servo motor 501 is controlled by the console 301 to run, and the servo motor 501 drives the bidirectional lead screw 5 to rotate. Rotating the bidirectional lead screw 5 pulls the distance between the two sets of first clamping plates 6 closer, so that the first clamping plates 6 clamp the outer side of the middle part of the pipe.

[0028] At the same time, the third hydraulic rod 8 on the fixed plate 801 moves synchronously with the first clamping plate 6, driving the second clamping plate 9 on the connecting plate 802 to clamp the outer sides of both ends of the pipe synchronously. Then, the control console 301 sends an extension command to the second hydraulic rod 701, extending the second hydraulic rod 701 to reduce the height of the pressure plate 702, so that the pressure plate 702 presses the pipe.

[0029] When positioning the pipeline, extend the first hydraulic rod 3 to raise the height of the top plate 4, so that the first support plate 7 and the second support plate 10 lift the pipeline upward. Rotate the universal stop wheel 2 to drive the base 1 to move. After moving the pipeline to the designated laying position, lock the universal stop wheel 2 and extend and retract the first hydraulic rod 3 to adjust the pipeline laying height so that both ends of the pipeline are stably aligned with the designated laying position.

[0030] Through the above steps, the top plate 4 is used to fix the bidirectional screw 5, and the operation of each structure of the device is controlled by the control component. The bidirectional screw 5 is rotated to flexibly adjust the distance between the two sets of first clamping plates 6. The first clamping plates 6 clamp and fix the pipe according to the actual diameter of the pipe. The first support plate 7 supports the pipe channel. The pressing component presses and fixes the pipe from top to bottom, and the position of the pipe is initially fixed in the device. The third hydraulic rod 8 is extended and retracted according to the actual length of the pipe. The position of the third hydraulic rod 8 is fixed in the first clamping plate 6 by the fixing component. The extension and retraction of the third hydraulic rod 8 adjusts the position of the second clamping plate 9 and moves the second clamping plate 9 to both ends of the pipe. The second clamping plate 9 clamps the outer sides of both ends of the pipe. The second support plate 10 supports both ends of the pipe channel to ensure that the pipe is placed in a balanced position. The universal stop wheel 2 is rotated to flexibly move the position of the base 1. The first hydraulic rod 3 is extended and retracted simultaneously to adjust the height of the top plate 4 and move the pipe to the designated laying height. This ensures the stability of the clamping center of gravity according to the pipe length, improves the stability of the pipe during movement, and ensures the rapid and accurate positioning of the pipe laying position.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
