Description

Technical Field

[0001] The utility model relates to a docking auxiliary device, in particular to an auxiliary docking lifting device for HDPE drainage pipes. Background Art

[0002] HDPE pipe joints often adopt heat shrinkable sleeves for connection, and it is difficult to control the construction quality of the joints. There are often leakage phenomena at the pipe joints during the water tightness test, and multiple rework treatments are required. According to past experience, pipe welding can be divided into welding above the trench and welding inside the trench. When welding above the trench, since the length of the well section is generally 30m - 50m, it is very inconvenient to lower the pipe as a whole, and the joint position is extremely easy to be damaged during the pipe lowering process. Therefore, only welding inside the trench can be selected. According to the specification requirements, the trench bottom width and slope ratio are used to excavate the trench. When welding the pipe, there is insufficient operating space for the extrusion welding gun and the blowtorch, and the bottom of the pipe cannot be welded, making it difficult to ensure the construction quality.

[0003] In view of the above defects, the designer actively conducts research and innovation in order to create an auxiliary docking lifting device for HDPE drainage pipes, making it more valuable in industrial use. Summary of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide an auxiliary docking lifting device for HDPE drainage pipes.

[0005] An auxiliary docking lifting device for HDPE drainage pipes of the utility model includes a mounting plate fixed to the foundation. A plurality of equally spaced bases are fixed on the mounting plate. A lower slide rail is installed between the end plates of the base. A cross-shaped lifting rod is installed on the lower slide rail through a slider. The lower end of the lifting rod is movably connected to the slider through a shaft, and the upper end of the lifting rod has a limiting part for supporting the drainage pipe.

[0006] When this auxiliary docking lifting device for HDPE drainage pipes is in use, the pipe is limited by the limiting part, and the pipe can be lifted for easy docking.

[0007] Furthermore, the limiting part includes a support plate. An upper slide rail is installed below the support plate. The upper end of the lifting rod is movably installed with a slider through a shaft. The slider cooperates with the upper slide rail, and the middle part of the support plate is concave.

[0008] The main body of this limiting part is a support plate with a concave middle part. After the pipe is clamped into this groove, the limiting can be completed, and the lifting rod can drive the support plate to move up and down.

[0009] Furthermore, the limiting part is a roller installed between the top ends of the lifting rods.

[0010] The limiting part is a roller at the top. The roller can be clamped on the outer wall of the pipe, and can provide auxiliary rotation, and can rotate the pipe when necessary.

[0011] Furthermore, there is a cross beam between the lower ends of the lifting rods. A screw rod is installed on the end plate of the base, and there are screw holes on the cross beam that cooperate with the screw rod.

[0012] The cross beam at the lower end of the lifting rod is used to cooperate with the screw rod. The two ends of the screw rod have reverse threads. When the screw rod rotates, it can drive the "X"-shaped lifting rods to move inwards / outwards synchronously, thereby satisfying the lifting operation.

[0013] Furthermore, a motor for synchronously driving multiple screw rods to rotate simultaneously is fixed on the mounting plate.

[0014] The screw rods are synchronously driven by the motor for lifting operation, which facilitates the lifting operation of the pipe.

[0015] Furthermore, the end of the screw rod extends out of the base, and two identical first sprockets are fixed on the screw rod. The first chains are staggeredly installed on the first sprockets between adjacent bases. A second sprocket is fixed on the output shaft of the motor, and the second sprocket is driven by a second chain between adjacent first sprockets.

[0016] The first sprockets are installed at the tail ends of the screw rods, and the first sprockets are driven by the first chains. The second sprocket installed on the output shaft of the motor is driven by a second chain between adjacent first sprockets, achieving the purpose of synchronously driving each screw rod to move and satisfying the synchronous lifting operation of multiple lifting rods.

[0017] By means of the above solution, the present invention has at least the following advantages: This kind of HDPE drainage pipe auxiliary docking and lifting device, when in use, drives the lifting rods to contract and expand through the motor, and then completes the lifting operation of the limiting part at its top, jacks up the pipe, which is convenient for subsequent processing. After the processing is completed, it can also drive the pipe to move downwards, facilitating the transfer of materials.

Specific embodiments

[0024] The following combines the accompanying drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0025] Refer to Figures 1-3 , the lower end of this HDPE drainage pipe auxiliary docking and lifting device is a mounting plate 1 that is connected to the foundation structure. The bases 2 evenly arranged on the mounting plate 1 are used to install the lifting rods 4. The lifting rods 4 include four long rods, the middle parts of which are movably connected by shafts, and the long rods on both sides are respectively arranged in a crossed manner to form a movable mechanism that can rotate relying on the shaft. The lower end of the lifting rod 4 moves back and forth through the movement of the lower slide rail 3. When the lower end of the lifting rod 4 contracts inward, its upper end can move upward.

[0026] Refer to Figure 2 , which is the first embodiment of the present utility model. In this embodiment, the upper end of the lifting rod 4 also cooperates with the upper slide rail 6 through a slider, so that the support plate 5 installed through the slider moves at the top of the lifting rod 4. While satisfying the up and down movement of the lifting rod 4, the relative position of the lifting rod 4 can also be limited. At the same time, the middle part of the support plate 5 is of a concave structure, which matches the outer diameter of the pipe and can provide good support for the pipe.

[0027] Refer to Figure 1 , when necessary, the support plate 5 can be replaced. The roller 7 is movably installed at the top of the lifting rod 4 through a shaft. The roller 7 can support on the side wall of the pipe. When performing the lifting operation, the roller 7 can roll on the side wall of the pipe, facilitating the lifting of the pipe.

[0028] When necessary, a braking structure can be installed at the end of the roller 7 and the lifting rod 4 to lock the roller 7. When processing the pipe, the rotation of the roller 7 can be avoided to prevent the pipe from rotating. The brake can also be released to make the pipe rotate.

[0029] See Figure 1 , the cross beam 8 at the lower end of the lifting rod 4 is movably installed on the lifting rod 4 through a shaft. The cross beam 8 is matched with the screw rod 9. When the screw rod 9 rotates, the cross beam 8 can be driven to move, completing the movement operation of the lifting rod 4.

[0030] See Figure 3 , which is the second embodiment of the present invention. The motor 10 fixed on the mounting plate 1 can drive the screw rod 9 to rotate synchronously, completing the operation of all the lifting rods 4.

[0031] A second sprocket 13 is fixed on the output shaft of the motor 10. Two identical first sprockets 11 are fixed at the end of each screw rod 9. The adjacent first sprockets 11 are connected by the first chains 12 arranged in a staggered manner. The second sprocket 13 is connected to the adjacent first sprocket 11 by the second chain 14. Therefore, when the motor 10 works, all the screw rods 9 can be driven to rotate synchronously.
