Description

Technical Field

[0001] This utility model relates to the field of mining machinery technology, specifically a hoisting device for facilitating the installation of ultra-large and ultra-heavy pipelines underground. Background Technology

[0002] In downhole operations, the installation and transportation of ultra-large and ultra-heavy pipelines has always been a technical challenge. Traditional methods mainly rely on the following two approaches: Manual handling and hoisting: This method involves multiple people working together, resulting in low efficiency, high labor intensity, and potential safety hazards. Fixed hoisting equipment: Due to the narrow space and complex terrain underground, fixed hoisting equipment is difficult to move flexibly, and is inconvenient to disassemble and transport; In pipeline installation projects, especially for ultra-large and ultra-heavy pipelines, traditional installation methods often face many challenges, such as low construction efficiency, difficulty in ensuring accurate installation and stable fixation of pipelines; significant safety hazards during installation, which can easily lead to construction accidents due to uneven weight distribution on the pipelines; and high installation costs, including labor and equipment costs. In existing technologies, flatbed trucks are usually only used for transportation and cannot be directly involved in hoisting operations, which results in pipeline installation requiring multiple transfers, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a hoisting device for easy installation of ultra-large and ultra-heavy pipelines in underground wells, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A hoisting device for facilitating the installation of ultra-large and ultra-heavy pipelines in underground wells, comprising a water pipe, characterized in that it further comprises: A flatbed trailer base for transporting the water pipes, the flatbed trailer base including a fixed flatbed; A lifting assembly is installed on the fixed flatcar for lifting the water pipe. The lifting assembly includes a lower robotic arm installed on the fixed flatcar and an upper robotic arm connected to the lower robotic arm. A hoist assembly for lifting the water pipe, the hoist assembly including a hoist mounted on the upper robotic arm.

[0005] Furthermore, a railway track is laid underground, and a flat wheel is installed at the lower end of the fixed flatcar corresponding to the position of the railway track. The fixed flatcar moves along the railway track by means of the flat wheel.

[0006] Furthermore, the fixed flatcar includes a fixed flatcar platform, the lower robotic arm is disposed on the upper surface of the fixed flatcar platform, and there are two sets of the lower robotic arms, which are symmetrically distributed.

The connecting cylinders are connected to the end of one set of upper robotic arms, and the lower robotic arms are rotatably connected to the corresponding upper robotic arms through the connecting cylinders.

[0008] Furthermore, a support rod is rotatably provided on the lower robotic arm near the upper robotic arm, and multiple sets of circular holes are provided on the upper robotic arm near the lower robotic arm to allow the end of the support rod to be inserted.

[0009] Furthermore, a gourd is hung at the lower end of another set of upper robotic arms, and a gourd rope is fitted onto the gourd; Each of the fixed flatbed platforms has a column at the upper end corresponding to the position of each of the lower robotic arms, and each column has a fixed pulley at the upper end.

[0010] Furthermore, one end of the gourd rope passes around the gourd and is wound around the water pipe, while the other end of the gourd rope passes around the fixed pulley and is wound onto the winding device.

[0011] Furthermore, flatbed railings are provided on both sides of the fixed flatbed platform.

[0012] Furthermore, both the lower robotic arm and the upper robotic arm employ a hydraulic telescopic structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The integrated transportation and hoisting reduces the number of transfers, improves operational efficiency, and, based on the modification of flatbed trucks, eliminates the need to purchase additional large hoisting equipment; 2.

[0016] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0017] Example 1: Please see Figures 1 to 2 This utility model provides a technical solution: a hoisting device for easy installation of ultra-large and ultra-heavy pipelines in underground wells, including a water pipe 11, and further comprising: The flatbed car base is used to transport the water pipe 11.

The lower end of the fixed flatbed car 5 is equipped with flatbed wheels 3 corresponding to the position of the rails 16. The fixed flatcar 5 moves along the rail 16 via the flatcar wheels 3. After moving to the designated position, the fixed flatcar 5 can be fixed with rubber. The fixed flatcar 5 can be made of high-strength steel.

[0018] Example 2: like Figures 1-2 As shown, the hoisting device for facilitating the installation of ultra-large and ultra-heavy pipelines in underground wells disclosed in Embodiment 2 of this utility model has a structure that is basically the same as that in Embodiment 1, except that: A hoisting assembly is installed on the fixed flatcar 5 for hoisting the water pipe 11. The hoisting assembly includes a lower robotic arm 14 installed on the fixed flatcar 5 and an upper robotic arm 15 connected to the lower robotic arm 14. The fixed flatcar 5 includes a fixed flatcar platform 1, and the lower robotic arm 14 is disposed on the upper surface of the fixed flatcar platform 1. There are two sets of the lower robotic arms 14, and the two sets of the lower robotic arms 14 are symmetrically distributed. A steel plate 2 is provided between the lower ends of the two sets of lower robotic arms 14 and the upper ends of the fixed flatbed platform 1, and the lower robotic arms 14 are fixed to the fixed flatbed platform 1 by the steel plate 2. The steel plate 2, the lower robotic arm 14, and the fixed flatbed platform 1 are all fixed with bolts, which can be quickly disassembled to adapt to different operating scenarios and transportation.

[0019] The upper robotic arm 15 is provided in two sets, and a spiral bracket 8 is provided between the two sets of upper robotic arms 15. The two sets of upper robotic arms 15 are connected by the spiral bracket 8. Both sets of lower robotic arms 14 are provided with connecting cylinders 7 at their upper ends. The connecting cylinders 7 are connected to the end of one set of upper robotic arms 15. The lower robotic arm 14 is rotatably connected to the corresponding upper robotic arm 15 through the connecting cylinders 7. The lower robotic arm 14 is rotatably provided with a support rod 13 near the upper robotic arm 15, and the upper robotic arm 15 near the lower robotic arm 14 has multiple sets of round holes that allow the end of the support rod 13 to be inserted. The end of the support rod 13 away from the lower robotic arm 14 is inserted into the round hole to support the upper robotic arm 15. At the same time, the extension angle of the upper robotic arm 15 can be adjusted by inserting it into the round hole at different positions. The extension length of the other set of upper robotic arms 15 can be adjusted by turning the screw bracket 8 with a wrench, so that the end of the upper robotic arm 15 contacts the tunnel wall and is supported by the tunnel wall. Both the lower robotic arm 14 and the upper robotic arm 15 adopt a hydraulic telescopic structure, with a maximum extension length of 3-5 meters. After the lower robotic arm 14 and the upper robotic arm 15 are retracted, they are flush with the fixed flatcar 5.

[0020] Example 3: like Figures 1-2 As shown, the hoisting device for facilitating the installation of ultra-large and ultra-heavy pipelines in underground wells disclosed in Embodiment 3 of this utility model has a structure that is basically the same as that in Embodiment 2, except that: A hoist assembly for lifting the water pipe 11, the hoist assembly including a hoist 10 disposed on the upper robotic arm 15; Another set of upper robotic arms 15 has a hoist 10 hanging at the lower end, and a hoist rope 6 is fitted on the hoist 10; The upper end of the fixed flatbed platform 1 is provided with a column 4 corresponding to the position of each of the lower robotic arms 14, and the upper end of each column 4 is provided with a fixed pulley 9.

Hook one end of the gourd rope 6 onto the water pipe 11, then start the winding device. Through the cooperation of the winding device and the gourd rope 6, the water pipe 11 is lifted and moved to a suitable position.

[0021] The specific solution is as follows: by cooperating with the flatbed wheel 3 and the rail 16, the fixed flatbed platform 1 is transported to the designated location, and then the flatbed 5 is fixed with rubber pads.

Then, one end of the support rod 13 is inserted into the round hole on the upper robotic arm 15, and the screw bracket 8 is turned with an adjustable wrench to extend one end of the upper robotic arm 15 to the tunnel wall to ensure its stability. Then hang the hook of gourd 10 inside the iron ring on the upper robotic arm 15; Hook one end of the gourd rope 6 onto the pipeline, start the winding device, and gradually lift the water pipe 11 with the gourd rope 6 and move it to a suitable connection position. After the water pipe 11 is moved to the appropriate position, it is fixed in place to ensure that the installation is secure. After the water pipe 11 is installed, remove the hoist 10 and the lower mechanical arm 14, and store them properly for future use.
