Description

[0001] The present invention relates to the field of pipeline supports, in particular to a hydraulic pipeline support for building construction projects. Background Art

[0002] Building construction projects refer to various types of housing buildings and their ancillary facilities, as well as the supporting lines, pipelines, equipment installation projects and indoor and outdoor decoration projects. The lines and pipelines used in the house construction process are relatively long and are rolled together. When in use, one end of the lines and pipelines needs to be pulled and dragged to the required position.

[0003] In the prior art, a Chinese patent document with publication number CN114542812A proposes a hydraulic pipeline support for building construction projects, which solves the problem that when multiple hydraulic pipelines are piled together and moved, large friction is easily generated, affecting their use. However, in actual application, there is still a problem that the friction between the pipeline and the support is large during use, and a large force is required to pull the pipeline, making it difficult to pull the pipeline. Therefore, we disclose a hydraulic pipeline support for building construction projects to meet the construction demand for easy pulling of pipelines. Summary of the Invention

The top end of the fixed frame is fixedly connected with a second limiting rod.

[0008] Preferably, one end of the connecting plate is fixedly connected with a first fixed shaft. The upper end of the first fixed shaft is rotatably connected with a second pipeline roller. The top end of the second pipeline roller is rotatably connected with a first limiting plate. One end of the first limiting plate is fixedly connected with a first limiting block.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a hydraulic pipeline support for building construction, which has the following beneficial effects:

[0019] 1. For the hydraulic pipeline support for building construction, when an operator pulls the pipeline body to drive the first pipeline roller to rotate, the gear will be driven to rotate, so that the gear drives the rack, the connecting rod and the current-limiting block to move upward, enabling the liquid in the middle of the connecting pipe to flow. Then, when the operator pulls the pipeline body and lays it on the ground, the first pipeline roller will press down the first hydraulic cylinder under the gravity of the pipeline body, causing the liquid in the first hydraulic cylinder to flow through the connecting pipe to the second hydraulic cylinder, making the second hydraulic cylinder drive the second limiting rod to move upward. As a result, a relatively obvious height difference is formed between the pipeline reel body and the pulled end of the pipeline body, which is more conducive to the operator pulling the pipeline body. After the pipeline body stops being pulled, the telescopic rod and the second spring will drive the rack back to its original position. When the first pipeline roller is not affected by the pulling gravity of the pipeline, the first spring will help the first hydraulic cylinder and the second hydraulic cylinder return to their original positions, causing the first pipeline roller to rotate in the reverse direction, making the gear drive the rack to move downward to its original position. Thus, the connecting rod drives the current-limiting block to move downward to block the liquid flow in the connecting pipe, fixing the top height of the first hydraulic cylinder and the second hydraulic cylinder to its original position, that is, the position where the pipeline body is not easy to be pulled, preventing unnecessary pipeline bodies from being released, increasing the operator's operation of winding the pipeline body, and also avoiding the potential safety hazards caused by the placement of excess pipeline bodies on the ground.

[0020] 2. For the hydraulic pipeline support for building construction, the position of the pipeline body is restricted by the connecting plate through the second pipeline roller and the first limiting plate, which is beneficial to the placement of the pipeline body and convenient for use. After the connecting frame moves in the moving hole, its position is restricted, enabling the operator to move the connecting frame according to the size of the pipeline body to adjust the position of the third pipeline roller, so that the third pipeline roller restricts the position of the pipeline body, thereby making the device more practical.

[0021] 3. The hydraulic pipeline support for building construction can be rotated through the second limiting plate, so that the second limiting plate can limit the position of the first limiting rod through the fourth spring, and the first limiting rod can limit the relative position between the second limiting plate and the second limiting rod. Thus, the operator can directly sleeve the coiled pipeline body onto the outer wall of the second limiting rod, which is convenient for the operator to use and saves operation time.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a hydraulic pipeline support for building construction projects.

[0032] In a typical implementation manner of the present application, as Figures 1 - 7As shown in the figure, a hydraulic pipeline support for building construction projects includes a fixed bottom plate 1. At one end of the fixed bottom plate 1, two first hydraulic cylinders 2 are fixedly connected. At the other end of the fixed bottom plate 1, two second hydraulic cylinders 3 are fixedly connected. A connecting pipe 4 is fixedly connected between the first hydraulic cylinder 2 and the second hydraulic cylinder 3. One end of the connecting pipe 4 is fixedly connected to a flow-limiting cylinder 6. A flow-limiting block 7 is movably sleeved inside the flow-limiting cylinder 6. A connecting rod 8 fixedly connected to the top end of the flow-limiting block 7 penetrates outside the flow-limiting cylinder 6. The top end of the connecting rod 8 is fixedly connected to a rack 9. One end of the rack 9 meshes with a gear 10. The middle part of the gear 10 is fixedly connected to a first pipeline roller 11. The lower end of the first pipeline roller 11 is rotatably connected to a connecting plate 12. Limit bars 13 are fixedly connected to both ends of the rack 9. The outside of the limit bars 13 is slidably connected to a limit frame 14. The limit frame 14 is fixedly connected to the connecting plate 12 through a limit frame 17. A telescopic rod 15 and a second spring 16 fixedly connected to the bottom end of the limit frame 17 are both fixedly connected to the rack 9. The connecting rod 8 is slidably connected to the limit frame 14. The connecting rod 8 is movably sleeved with the connecting plate 12. The connecting plate 12 is fixedly connected to the first hydraulic cylinder 2. Fixed frames 28 are fixedly connected to the top ends of both second hydraulic cylinders 3. A second limiting rod 32 is fixedly connected to the top end of the fixed frame 28. First springs 5 are fixedly connected to the middle parts of the first hydraulic cylinder 2 and the second hydraulic cylinder 3. A pipeline is fixedly connected between the two second hydraulic cylinders 3. A third spring 18 is fixedly connected to the top end of the flow-limiting block 7. The third spring 18 is fixedly connected to the flow-limiting cylinder 6. The connecting rod 8 is located in the middle of the third spring 18. A plurality of rubber strips are fixedly connected to the outer wall of the flow-limiting block 7. The rubber strips of the flow-limiting block 7 are vertically distributed. When in use, since two first hydraulic cylinders 2 are fixedly connected to one end of the fixed bottom plate 1, and two second hydraulic cylinders 3 are fixedly connected to the other end of the fixed bottom plate 1, and a connecting pipe 4 is fixedly connected between the first hydraulic cylinder 2 and the second hydraulic cylinder 3, the fixed bottom plate 1 can limit the positions of the first hydraulic cylinder 2 and the second hydraulic cylinder 3 at the same time, and the first hydraulic cylinder 2 and the second hydraulic cylinder 3 are connected. Since one end of the connecting pipe 4 is fixedly connected to a flow-limiting cylinder 6, and a flow-limiting block 7 is movably sleeved inside the flow-limiting cylinder 6, and a connecting rod 8 fixedly connected to the top end of the flow-limiting block 7 penetrates outside the flow-limiting cylinder 6, the flow-limiting block 7 inside the flow-limiting cylinder 6 can cut off the liquid flow in the connecting pipe 4, and the connecting rod 8 can limit the position of the flow-limiting block 7, so that the top heights of the first hydraulic cylinder 2 and the second hydraulic cylinder 3 are fixed. Since the top end of the connecting rod 8 is fixedly connected to a rack 9, one end of the rack 9 meshes with a gear 10, the middle part of the gear 10 is fixedly connected to a first pipeline roller 11, and the lower end of the first pipeline roller 11 is rotatably connected to a connecting plate 12, when an operator pulls the pipeline body to drive the first pipeline roller 11 to rotate, the gear 10 will be driven to rotate, the gear 10 will drive the rack 9 to move upward, so that the rack 9 will drive the flow-limiting block 7 to move upward through the connecting rod 8, and the liquid in the middle of the connecting pipe 4 can flow.After that, when the operator pulls the pipeline body and lays it on the ground, the first pipeline roller 11 will press down the first hydraulic cylinder 2 under the gravity of the pipeline body, so that the liquid in the first hydraulic cylinder 2 flows through the connecting pipe 4 to the second hydraulic cylinder 3. Since fixed frames 28 are fixedly connected to the tops of both second hydraulic cylinders 3, and a second limiting rod 32 is fixedly connected to the top of the fixed frame 28, the second hydraulic cylinder 3 drives the second limiting rod 32 to move upward, so that a relatively obvious height difference is formed between the pipeline reel body and the pulling end of the pipeline body, which is more conducive to the operator pulling the pipeline body. Since limiting strips 13 are fixedly connected to both ends of the rack 9, and a limiting frame 14 is slidably connected to the outside of the limiting strip 13, and the limiting frame 14 is fixedly connected to the connecting plate 12 through a limiting frame 17, the connecting plate 12 restricts the position of the limiting frame 14 through the limiting frame 17, so that the limiting frame 14 restricts the moving position of the rack 9 through the limiting strip 13. Since the telescopic rod 15 and the second spring 16 fixedly connected to the bottom end of the limiting frame 17 are both fixedly connected to the rack 9, after the pipeline body stops being pulled, the telescopic rod 15 and the second spring 16 will drive the rack 9 back to its original position. Since the connecting rod 8 is movably sleeved with the connecting plate 12, the connecting plate 12 restricts the moving position of the connecting rod 8. Since first springs 5 are fixedly connected to the middle parts of both the first hydraulic cylinder 2 and the second hydraulic cylinder 3, when the first pipeline roller 11 is not affected by the pulling gravity of the pipeline, the first spring 5 will help the first hydraulic cylinder 2 and the second hydraulic cylinder 3 to return to their original positions, so that the first pipeline roller 11 rotates reversely, and the gear 10 drives the rack 9 to move downward to its original position, so that the connecting rod 8 drives the flow limiting block 7 to move downward to block the liquid flow in the connecting pipe 4, fixing the top height of the first hydraulic cylinder 2 and the second hydraulic cylinder 3 to the original position, that is, the position where the pipeline body is not easy to be pulled, to avoid unnecessary pipeline bodies from being released, increasing the operation of the operator to wind up the pipeline body, and also avoiding the safety hazards existing in the placement of redundant pipeline bodies on the ground. Since a third spring 18 is fixedly connected to the top end of the flow limiting block 7, and the third spring 18 is fixedly connected to the flow limiting cylinder 6, and the connecting rod 8 is located in the middle of the third spring 18, the position of the flow limiting block 7 when blocking the liquid flow in the connecting pipe 4 is stable. Since a plurality of rubber strips are fixedly connected to the outer wall of the flow limiting block 7, and the rubber strips of the flow limiting block 7 are vertically distributed, the effect of the flow limiting block 7 blocking the liquid is good, and the friction between the flow limiting block 7 and the flow limiting cylinder 6 is reduced, which is conducive to the movement of the flow limiting block 7 and ensures the normal use of the device.,

[0033] As a preferred implementation manner in this embodiment, refer to the attached Figure 4 and Figure 7, one end of the connecting plate 12 is fixedly connected with a first fixed shaft 19. The upper end of the first fixed shaft 19 is rotatably connected with a second pipeline roller 20. The top end of the second pipeline roller 20 is rotatably connected with a first limiting plate 21. One end of the first limiting plate 21 is fixedly connected with a first limiting block 22. The top end of the first fixed shaft 19 is fixedly connected with a second limiting block 23. The second limiting block 23 is movably clamped with the first limiting block 22. Two moving holes 24 are opened at one end of the connecting plate 12. A connecting frame 25 is slidably connected in the moving holes 24. The upper end of the connecting frame 25 is rotatably connected with a third pipeline roller 26. Four limiting rings 27 are fixedly connected to the bottom end of the connecting frame 25. Blocks are fixedly connected to both ends of the inner wall of the moving hole 24. Four clamping slots are opened at the bottom end of the connecting frame 25 and are movably clamped with the blocks of the moving hole 24. One end of the first limiting plate 21 is located at the top end of the connecting frame 25. By fixedly connecting one end of the connecting plate 12 with the first fixed shaft 19 and rotatably connecting the upper end of the first fixed shaft 19 with the second pipeline roller 20, the connecting plate 12 restricts the position of the pipeline body through the second pipeline roller 20. By rotatably connecting the top end of the second pipeline roller 20 with the first limiting plate 21, fixedly connecting one end of the first limiting plate 21 with the first limiting block 22, and fixedly connecting the top end of the first fixed shaft 19 with the second limiting block 23, and the second limiting block 23 being movably clamped with the first limiting block 22, the first fixed shaft 19 restricts the position of the first limiting plate 21 through the second limiting block 23 and the first limiting block 22, so that the first limiting plate 21 restricts the position of the pipeline body, which is also beneficial to the placement of the pipeline body and convenient for use. By opening two moving holes 24 at one end of the connecting plate 12, slidingly connecting the connecting frame 25 in the moving holes 24, and rotatably connecting the upper end of the connecting frame 25 with the third pipeline roller 26, the connecting plate 12 restricts the position of the connecting frame 25 through the moving holes 24, so that the connecting frame 25 restricts the position of the third pipeline roller 26. By fixedly connecting blocks to both ends of the inner wall of the moving hole 24 and opening four clamping slots at the bottom end of the connecting frame 25 and being movably clamped with the blocks of the moving hole 24, the position of the connecting frame 25 after moving in the moving holes 24 is restricted, enabling the operator to move the connecting frame 25 according to the size of the pipeline body to adjust the position of the third pipeline roller 26, so that the third pipeline roller 26 restricts the position of the pipeline body, thereby making the device more practical.

[0034] As a preferred implementation manner in this embodiment, refer to the attached Figure 2, one end of the fixing bracket 28 is rotatably connected to a second limiting plate 29. The top end of the second limiting plate 29 is fixedly connected to a fourth spring 31. One end of the fourth spring 31 is fixedly connected to a first limiting rod 30. One end of the first limiting rod 30 passes through the second limiting plate 29 and is movably sleeved with a second limiting rod 32. The second limiting rod 32 is a hollow rod, and the first limiting rod 30 is a T-shaped rod. By rotatably connecting one end of the fixing bracket 28 to the second limiting plate 29, fixedly connecting the fourth spring 31 to the top end of the second limiting plate 29, fixedly connecting one end of the fourth spring 31 to the first limiting rod 30, and movably sleeving one end of the first limiting rod 30 with the second limiting rod 32 after passing through the second limiting plate 29, the second limiting plate 29 can rotate, the second limiting plate 29 can limit the position of the first limiting rod 30 through the fourth spring 31, and the first limiting rod 30 can limit the relative position between the second limiting plate 29 and the second limiting rod 32. Thus, the operator can directly sleeve the coiled pipeline body onto the outer wall of the second limiting rod 32, which is convenient for the operator to use. By making the second limiting rod 32 a hollow rod, the weight of the second limiting rod 32 is reduced, and by making the first limiting rod 30 a T-shaped rod, the first limiting rod 30 is convenient to use.

[0035] Working principle of the present invention: When in use, the liquid flow in the connecting pipe 4 can be cut off by the flow-limiting block 7 in the flow-limiting cylinder 6, and the connecting rod 8 can limit the position of the flow-limiting block 7. Also, when the operator pulls the pipeline body to drive the first pipeline roller 11 to rotate, the gear 10 will be driven to rotate, causing the gear 10 to drive the rack 9 to move upward. Thus, the rack 9 drives the flow-limiting block 7 to move upward through the connecting rod 8, enabling the liquid in the middle of the connecting pipe 4 to flow. After that, when the operator pulls the pipeline body and lays it on the ground, the first pipeline roller 11 will press down the first hydraulic cylinder 2 under the gravity of the pipeline body, causing the liquid in the first hydraulic cylinder 2 to flow through the connecting pipe 4 to the second hydraulic cylinder 3, and the second hydraulic cylinder 3 drives the second limiting rod 32 to move upward. Thus, a relatively obvious height difference is formed between the pipeline coil body and the pulling end of the pipeline body, which is more conducive to the operator pulling the pipeline body. After the pipeline body stops being pulled, the telescopic rod 15 and the second spring 16 will drive the rack 9 back to its original position. When the first pipeline roller 11 is not affected by the pulling gravity of the pipeline, the first spring 5 will help the first hydraulic cylinder 2 and the second hydraulic cylinder 3 return to their original positions, causing the first pipeline roller 11 to rotate in the reverse direction, driving the gear 10 to move the rack 9 downward to its original position. Thus, the connecting rod 8 drives the flow-limiting block 7 to move downward to block the liquid flow in the connecting pipe 4, fixing the top height of the first hydraulic cylinder 2 and the second hydraulic cylinder 3 to their original positions, that is, the position where the pipeline body is not easy to pull, preventing unnecessary pipeline bodies from being released, increasing the operation of the operator to wind up the pipeline body, and also avoiding potential safety hazards caused by the placement of excess pipeline bodies on the ground.

[0036] The connecting plate 12 restricts the position of the pipeline body through the second pipeline roller 20. The first fixed shaft 19 restricts the position of the first limiting plate 21 through the second limiting block 23 and the first limiting block 22, so that the first limiting plate 21 restricts the position of the pipeline body, which is also beneficial to the placement of the pipeline body and convenient for use. The position of the connecting frame 25 after moving in the moving hole 24 is restricted, so that the operator can move the connecting frame 25 according to the size of the pipeline body to adjust the position of the third pipeline roller 26, so that the third pipeline roller 26 restricts the position of the pipeline body, thus making the device more practical;

[0037] The second limiting plate 29 can rotate, so that the second limiting plate 29 can restrict the position of the first limiting rod 30 through the fourth spring 31, so that the first limiting rod 30 can restrict the relative position of the second limiting plate 29 and the second limiting rod 32, so that the operator can directly sleeved the coiled pipeline body on the outer wall of the second limiting rod 32, which is convenient for the operator to use and saves operation time.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
