Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to a hoisting device for municipal engineering road pipeline construction. Background Technology

[0002] With the accelerating pace of urbanization, the scale and number of municipal engineering projects are growing exponentially, among which road and pipeline construction is a crucial component. Road and pipeline systems encompass various types, including water supply and drainage pipes, gas pipelines, and communication pipelines, playing a fundamental role in ensuring the normal operation of cities and the convenience of residents' lives. During pipeline construction, it is essential to accurately hoist pipes of various specifications and weights to designated trenches or installation locations, highlighting the increasing demand for hoisting equipment.

[0003] In the prior art, a Chinese patent document with publication number CN220664725U and publication date of March 26, 2024, was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a hoisting device for municipal engineering road pipeline construction, including a support base, a first rod body fixedly connected to the top of the support base, a second rod body slidably connected inside the first rod body, a winding box provided on the top of the support base, a motor provided at the rear end of the winding box, a steel wire rope wound on the winding box, a first roller provided on the side of the second rod body, a crossbar provided on the top of the second rod body, a second roller, a third roller, and a warning mechanism provided on the top of the crossbar, and an automatic placement mechanism provided at the end of the steel wire rope away from the winding box.

[0004] To address the challenges of hoisting pipelines during road construction, existing technology involves placing the pipeline between two clamping plates, pressing them down to bring them closer together, and moving the clamping plates to move the grooves and locking blocks within them. When the slots and grooves align, the telescopic springs within the grooves rebound, causing the locking blocks to engage in the slots. At this point, the clamping plates are fixed in place, securing the pipeline. However, this process lacks automatic alignment and clamping mechanisms, relying entirely on manual operation. If the pipeline is heavy, manually pressing down the clamping plates is difficult, increasing the operator's workload and potentially causing the pipeline to shift due to uneven force, making it impossible to accurately align the clamping position.

[0005] The purpose of this utility model is to provide a hoisting device for municipal engineering road pipeline construction, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides a hoisting device for municipal engineering road pipeline construction, including a base 1. A support column 11 is fixedly installed on the top of the base 1. A steel wire rope 12 is connected to the outer surface of the unwinding roller at the rear end of the top of the base 1. A hoisting connector 2 is fixedly connected to the other end of the steel wire rope 12. A connecting arc plate 3 is fixedly installed on both sides of the hoisting connector 2. A support plate 4 is fixedly installed on the outer surface of the connecting arc plate 3. A push-pull plate 31 is rotatably connected to both sides of the bottom end of the connecting arc plate 3. A push-pull plate 32 is rotatably connected to the other end of the push-pull plate 31. A clamping ring plate 33 is fixedly connected to the other end of the left push-pull plate 32. A clamping ring plate 34 is fixedly connected to the other end of the right push-pull plate 32.

[0027] Furthermore, the pipe is clamped by the cooperation of clamping ring plate 33 and clamping ring plate 34, initially wrapping the pipe body. During lifting, push-pull plate 31 and push-pull plate 32 form a linkage structure, so that the locking ring plate closes synchronously. This can cleverly convert the gravity generated by the pipe body's own weight into a clamping force on the pipe body. At the same time, the clamping action is automatically completed during the lifting process, and automatic locking is achieved by using clamping ring plate 33 and clamping ring plate 34.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, cavities 35 are provided on the inner sides of clamping ring plate 1 33 and clamping ring plate 2 34. An air suction box 45 is fixedly installed inside the cavity 35. An air pump 41 is fixedly installed on the top bracket of the support plate 4. An air suction diversion hose 42 is fixedly installed at the air suction end of the air pump 41. Two sets of air suction diversion hoses 42 are provided. A one-way valve 43 is fixedly installed on the other end of the two sets of air suction diversion hoses 42. A connecting pipe 44 is fixedly installed on the other end of the one-way valve 43. The other end of the connecting pipe 44 is fixedly installed inside the top of the air suction box 45. A suction cup 46 is fixedly installed on the inner side of the air suction box 45.

[0030] Furthermore, the air pump 41 starts working, and its suction end generates negative pressure suction through two sets of suction diversion hoses 42 to the corresponding one-way valves 43 and connecting pipes 44 respectively. The one-way valves 43 can effectively prevent air backflow and ensure a stable negative pressure state. The negative pressure is transmitted through the connecting pipes 44 to the suction box 45 installed in the cavity 35 of clamping ring plate 1 33 and clamping ring plate 2 34, which reduces the air pressure inside the suction box 45. At this time, the suction cups 46 on the inner side of the suction box 45 are tightly adsorbed on the outer wall of the pipe under the action of the internal and external air pressure difference, further enhancing the fixing effect of clamping ring plate 1 33 and clamping ring plate 2 34 on the pipe.

[0031] The solution uses a PLC as the core control component. The PLC establishes a connection with the air pump 41 through RS-485 communication. When the air pump 41 needs to be started, the PLC sends a start command to the air pump 41, causing the air pump 41 to start.

[0032] The working principle of the hoisting device used in the construction of road pipelines in this municipal engineering project will be explained in detail below.

[0033] like Figure 1-5 As shown, during use, the entire hoisting device is first fixed on a stable surface in the construction area using the base 1, ensuring that the support column 11 is vertical, providing a stable foundation for subsequent hoisting operations. Then, the unwinding roller at the top rear of the base 1 is operated, causing the steel wire rope 12 wound around it to slowly descend, pulling the hoisting connector 2 and components connected to it, such as the connecting arc plate 3 and the support plate 4, down together. The pipe is clamped by the cooperation of clamping ring plate 1 33 and clamping ring plate 2 34, initially wrapping the pipe body. During hoisting, the push-pull plate 1 31 and push-pull plate 2 32 form a linkage structure, causing the locking ring plate to close synchronously. This cleverly converts the gravity generated by the pipe body's own weight into a clamping force on the pipe body, automatically completing the clamping action during hoisting. The clamping action is achieved using clamping ring plate 1 33 and clamping ring plate 2 34. After the second plate 34 is automatically locked, the air pump 41 on the top bracket of the support plate 4 is started. Under the control of the PLC, the air pump 41 starts to work. Its suction end generates negative pressure suction through two sets of suction diversion hoses 42 to the corresponding one-way valves 43 and connecting pipes 44 respectively. The one-way valves 43 can effectively prevent air backflow and ensure the stability of the negative pressure state. The negative pressure is transmitted through the connecting pipes 44 to the suction box 45 installed in the cavity 35 of the clamping ring plate 33 and the clamping ring plate 34, which reduces the air pressure inside the suction box 45. At this time, the suction cups 46 on the inner side of the suction box 45 are tightly adsorbed on the outer wall of the pipe under the action of the internal and external air pressure difference, which further enhances the fixing effect of the clamping ring plate 33 and the clamping ring plate 34 on the pipe and prevents the pipe from loosening or slipping during hoisting.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
