Technical Field

[0001] This disclosure relates to the field of pipeline hoisting technology, and in particular to a pipeline hoisting tool. Background Technology

[0002] In high-rise buildings, it is often necessary to hoist pipes. Hoisting pipes with a crane will occupy a large working area. Therefore, cranes cannot be used in narrow working spaces such as urban villages. In addition, the crane has a large weight. When working close to the trench, it will increase the load on the trench side and pose certain safety risks.

[0003] Existing hoisting tools have solved the problems of complex construction environments, tight schedules, and narrow passages between buildings in urban villages, making it difficult for construction machinery to work on the work surface. However, the existing hoisting tools have relatively fixed sizes and models, which are not very adaptable to different pipes to be hoisted. They cannot clamp pipes of different lengths and sizes, thus affecting the effect of pipe clamping. Utility Model Content

Detailed Implementation

[0028] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0030] Currently, existing hoisting tools have solved the problems of complex construction environments, tight schedules, and narrow passages between buildings in urban villages, making it difficult for construction machinery to work on the work surface. However, the size and model of existing hoisting tools are relatively fixed, which makes them less adaptable to different pipes to be hoisted. They cannot clamp pipes of different lengths and sizes, thus affecting the effectiveness of pipe clamping.

[0031] Based on this, the present disclosure provides a pipe hoisting tool. The present disclosure is equipped with a clamping mechanism, which adjusts the relative distance between the first clamping arm and the second clamping arm through an adjusting part, so that the clamping end extends into the inside of the pipe. This allows the first clamping arm and the second clamping arm to clamp pipes of different lengths and sizes, ensuring the structural stability and safety of the pipe clamping. The second clamping member of the present disclosure is used to contact the outer wall of the pipe to form a supporting state, which can effectively prevent the pipe from falling accidentally and improve construction safety.

[0032] The following is a detailed description of this pipeline hoisting tool through specific embodiments:

[0033] Reference Figures 1 to 5 As shown, this disclosure provides a pipe hoisting tool, including an operating platform 1, a hoisting component 2, and a clamping part 3. The bottom of the operating platform 1 has a sliding groove 4, and the hoisting component 2 is slidably connected to the sliding groove 4. The clamping part 3 includes an adjusting part 31, a first clamping component 32, and a second clamping component 33. The first clamping component 32 includes a first clamping arm 321 and a second clamping arm 322. The first clamping arm 321 and the second clamping arm 322 are connected to the adjusting part 31, and the first clamping arm 321 and the second clamping arm 322 have clamping ends. The two clamping ends are arranged opposite to each other, and the clamping ends are used to extend into the pipe. The adjusting part 31 is used to adjust the relative distance between the clamping ends. The second clamping component 33 is used to clamp the outer wall of the pipe 100.

[0034] This disclosure provides a clamping mechanism that adjusts the relative distance between the first and second clamping arms via an adjusting part, extending the clamping end into the pipe so that pipes of different lengths and sizes can be clamped by the first and second clamping arms, ensuring the structural stability and safety of the pipe clamping. The second clamping component of this disclosure is used to contact the outer wall of the pipe to form a supporting state, which can effectively prevent the pipe from falling accidentally and improve construction safety.

[0035] Specifically, the operating platform 1 of this disclosure can be configured as an operating lever, operating panel, or other structure, designed to adjust the overall position of the device and serve as a platform for installing the lifting component 2. The lifting component 2 of this disclosure enables the vertical movement of the pipeline and can be configured as a manual hoist or other lifting mechanism. Multiple frames 200 can be installed at the bottom of the operating platform 1, and a sliding groove 4 is provided on the bottom surface of the operating platform 1 facing the lifting mechanism. For ease of operation and layout, the sliding groove 4 can be positioned between two frames 200 for convenient movement, operation, and positioning. The lifting component 2 of this disclosure is positioned within the sliding groove and slidably connected to the sliding groove 4. This sliding connection can be achieved using a slide rail, slider, or other similar method. Furthermore, the operating platform 1 is mounted on the frame 200 via a bracket. The bracket and operating platform 1 are constructed using welded steel pipes and equipped with bucket wheels, allowing the device to move in four directions (front, back, left, and right), providing flexible use.

[0036] The clamping part disclosed herein includes an adjusting part 31, a first clamping member 32, and a second clamping member 33. The first clamping member 32 is used to extend into the pipeline 100 for the main lifting work, and the second clamping part 33 is used to support the outer wall of the pipeline to ensure the stability and safety of the pipeline during transportation. The first clamping part 32 and the second clamping part 33 form a stable clamping method for the pipeline 100 as a whole, which greatly improves the safety of pipeline transportation.

[0037] The adjustment part 31 disclosed herein is used to adjust the relative distance between the clamping ends, enabling the first clamping member 32 to adapt to pipelines of various lengths by adjusting the relative distance between the adjustment ends, thereby improving the adaptability of pipeline hoisting. For example, the second clamping part 32 includes a first clamping arm 321 and a second clamping arm 322 arranged opposite to each other. The first clamping arm 321 and the second clamping arm 322 are L-shaped, with the clamping ends on both sides horizontally aligned, and the opposite ends respectively connected to the adjustment part 31. For example, the adjustment part 31 can be configured as two electrically driven telescopic cylinders, telescopic hydraulic cylinders, or lead screw stepper motors, and has two protruding ends connected to the first clamping arm 321 and the second clamping arm 322, so that the two are brought closer or further apart, thereby adjusting the relative distance between the clamping ends. Furthermore, the adjustment part 31 may also be provided with a mounting housing, and a slide rail is provided inside the mounting housing. The protruding ends of the adjustment part 31 and parts of the first clamping arm 321 and the second clamping arm 322 are disposed inside the slide rail to restrict the movement path of the first clamping arm 321 and the second clamping arm 322.

[0038] In some embodiments, the first clamping arm 321 and the second clamping arm 322 have a connecting arm 323 and a clamping arm 324. The clamping arm 324 is configured as a clamping end. The two connecting arms 323 together form a semi-circular clamping space 325. One end of the connecting arm 323 is connected to the adjusting part 31, and the other end is connected to the clamping arm 324. The two clamping arms 324 are arranged horizontally, and the second clamping member 33 is disposed within the range of the clamping space 325.

[0039] In this embodiment, such as Figure 1 , 2 As shown in Figure 3, the first clamping arm 321 and the second clamping arm 322 of this disclosure have a connecting arm 323 and a clamping arm 324. The connecting arm 323 together form a semi-circular clamping space 325, which makes the clamping span of the first clamping member 32 larger and easier to place. It should be noted that the semi-circular clamping space 325 formed by the connecting arms 323 on both sides can be a regular semicircle or an elliptical semicircle. In this embodiment, the two connecting parts 323 are designed to form an integral arc transition, and the clamping space 325 refers to the area surrounded by the two. The clamping arm 324, as a component for lifting and carrying the pipe 100, contacts the inner wall of the pipe 100 during lifting. Its width and length are adapted according to the type of pipe. It can be understood that, in order to make the lifting more stable, the two clamping arms 324 enter the inner wall of the pipe 100 on both sides, and the surfaces of the two arms that contact the inside of the pipe 100 are set at the same level so that the pipe 100 is placed stably on the clamping arms 324. The second clamping member 33 of this disclosure is disposed in the clamping space 325. It can be configured to extend and retract from one side of the clamping arm 324 to the other side to contact the outer wall of the pipe, or the second clamping member 33 can be disposed on the central axis of the clamping space 325 and extend and retract vertically from top to bottom to contact the outer wall of the pipe 100.

[0040] In some embodiments, the clamping arm 324 is provided with a clamping plate 326, which is connected to the clamping arm 324 via a first telescopic mechanism 5, wherein the extension direction of the first telescopic mechanism 5 is the extension direction of the clamping arm 324.

[0041] In this embodiment, the clamping arm 324 is equipped with a clamping plate 326. If the clamping arm 324 is too long during use, the adjusting member 31 will drive the connecting arm 323 to move a considerable distance before it can enter the pipe 100 from its opening. This can restrict movement in confined spaces. This disclosure addresses this issue by using the clamping plate 326 in conjunction with the first telescopic mechanism 5. After the clamping arm 324 enters the inner wall of the pipe 100, the first telescopic mechanism 5 drives the clamping plate 326 to extend further into the pipe 100. This solves the problem of limited lifting space and allows for a longer clamping arm 324, improving the stability of clamping the pipe 100. Furthermore, a protective pad is provided on the surface of the clamping plate 326 that contacts the pipe 100 to protect the pipe 100.

[0042] In some embodiments, the second clamping member 33 includes a second telescopic mechanism 6 and a third clamping arm 331. The second telescopic mechanism 6 is connected to the adjusting part 31, and the telescopic direction of the second telescopic mechanism 6 is perpendicular to the outer wall of the pipe 100. The second clamping arm 322 is connected to the extended end of the second telescopic mechanism 6.

[0043] In this embodiment, the second clamping member 33 includes a second telescopic mechanism 6 and a third clamping arm 331. The second telescopic mechanism 6 is connected to the adjusting part 31. It should be noted that the adjusting part 31 only serves as the mounting position for the second telescopic mechanism 5, and the two do not produce any other connection relationship. Both the second telescopic mechanism 6 and the first telescopic mechanism 5 can be selected from telescopic cylinders, telescopic hydraulic cylinders, or stepper motors, etc. In this disclosure, an electric telescopic cylinder is specifically selected.

[0044] In some embodiments, the third clamping arm 331 includes a first clamping plate and a second clamping plate, which are connected by an adjusting member for adjusting the relative distance between the first clamping plate and the second clamping plate.

[0045] In this embodiment, the third clamping arm 331 includes a first clamping plate and a second clamping plate, and an adjusting member is used to adjust the relative distance between the first clamping plate and the second clamping plate. In use, after the first clamping member 32 clamps the pipe 100, the second telescopic mechanism 6 drives the third clamping arm 331 to descend vertically to a certain range. At this time, the relative distance between the first clamping plate and the second clamping plate is adjusted according to the width of the pipe 100 using the adjusting member. The second telescopic mechanism 6 then drives the third clamping arm 331 to continue descending, and the adjusting member drives the first clamping plate and the second clamping plate closer to the outer wall of the pipe 100. Specifically, to enable the first clamping plate and the second clamping plate to clamp the pipe 100 better, the surfaces of the first clamping plate and the second clamping plate that contact the pipe 100 can be set to an arc shape. This embodiment is configured to clamp the pipe 100 from both sides.

[0046] In some embodiments, the third clamping arm 331 includes an arc-shaped clamping plate 332 and a plurality of elastic elements 333, which are arranged in an array on the surface of the arc-shaped clamping plate 332 facing the pipe 100.

[0047] In this embodiment, the third clamping arm 331 includes an arc-shaped clamping plate 332 and multiple elastic elements 333. The multiple elastic elements 333 are arranged in an array on the surface of the arc-shaped clamping plate 332 facing the pipe 100. The elastic elements 333 disclosed herein can be elastic pads or springs, etc., and specifically springs are used in this disclosure. In use, the second telescopic mechanism 6 drives the third clamping arm 331 to descend vertically until the multiple elastic elements 333 on the arc-shaped clamping plate 332 contact the pipe 100 and continue to press, so that the multiple elastic elements 333 are compressed to a range that can be fixed. Specifically, the arc-shaped clamping plate 332 can be selected to have a larger and wider plate surface to accommodate more sizes of pipes 100. The arrangement of multiple elastic elements 333 allows pipes 100 of various models to be clamped. Furthermore, pads can be installed on multiple elastic elements 333 to ensure the contact surface and stability with the pipe 100, which can effectively prevent the pipe from falling accidentally and improve construction safety. The mechanism is small in size and light in weight, which is conducive to the stability after trench excavation, effectively avoids construction safety hazards, and is highly practical, reducing the frequency of equipment use and saving construction costs.

[0048] In some embodiments, the device further includes a slider and a limiting baffle 7. The lifting component 2 is connected to the slider, the slider slides in conjunction with the slide groove 4, and the limiting baffle 7 is disposed on both sides of the slide groove 4 in the extending direction. The limiting baffle 7 is used to limit the sliding range of the slider.

[0049] In this embodiment, a slider is provided inside the chute 4 opened in the operating platform 1, and the limiting baffle 7 is provided on both sides of the extension direction of the chute 4, so as to realize the longitudinal fine-tuning installation after the pipeline is lowered into the foundation pit.

[0050] In some embodiments, the lifting component 2 and the clamping part 3 are detachably connected to facilitate their maintenance and repair.
