[0002] With economic development and the accelerating pace of urbanization, a large number of people are settling in cities, and more and more buildings are being constructed. During the construction process, hoisting equipment is needed to transport materials such as cement, sand, gravel, steel bars, and pipe fittings.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] This utility model provides a pipe fitting gripping device for hoisting on construction sites, including a frame 1. The frame 1 adopts a split structure design with left block 2 and right block 3. An installation ring 101 is installed on the top of the frame 1. Supports 4 are evenly distributed at the bottom of the left block 2 and right block 3. Rollers 402 are rotatably connected to the supports 4 via a rotating shaft 401. Steel cables 403 are wound on the rollers 402. A motor 404 is fixedly connected to the right support 4. A rotor 405 is rotatably connected to the motor 404. On the left support 4... The steel cable 403 is the output end, and the steel cable 403 on the right-side bracket 4 is the tightening end. The rotor 405 is connected to the rotating shaft 401. The steel cable 403 collects the pipe 5. The left block 2 is provided with a receiving groove 201, and a hydraulic cylinder 202 is installed in the receiving groove 201. A slide rod 203 is slidably connected in the hydraulic cylinder 202. A limit seat 204 is fixedly connected in the right block 3. The limit seat 204 is detachably connected to the right end of the slide rod 203. A working gap is left between adjacent brackets 4.
[0021] In actual use, the pipe lifting device for construction sites utilizes an installation ring 101 installed on the top of frame 1. This allows the frame 1 to work in conjunction with external lifting tools to lift pipes. The distance between the left block 2 and the right block 3 is adjusted according to the number of pipes 5 to be lifted, increasing the overall number of pipes 5 that can be lifted. The hydraulic cylinder 202 in the left block 2 drives the sliding rod 203 to move to the right. Since the end of the sliding rod 203 is detachably connected to the limit seat 204 on the right block 3, the right block 3 is moved away from the left block 2, increasing the distance between the frame 1 and the original position. Then, workers manually thread a steel cable 403 through the bottom of the pipe 5 to be lifted, and then drive the motor 404 in the right support 4. The starting drive rotor 405 rotates the shaft 401 in the bracket 4, thereby tightening the steel cable 403 in the roller 402 of the right bracket 4 until the multiple sets of pipes 5 on the steel cable 403 are lifted up as a whole, completing the limiting work of the pipes 5. Then, the hoisting tool is used to hoist the limited pipes 5. By designing the frame 1 as a structure that can extend and retract left and right, and installing the steel cable 403 retraction structure at the bottom of the frame 1, the supporting work of multiple sets of pipes 5 is completed. Compared with the conventional method of manually tying the ropes by the workers, the technical solution adopted by this utility model can collect the pipes 5 relatively stably on multiple sets of steel cables 403. The overall structure is convenient for workers to operate and install, with a compact structure and reasonable spatial layout.
[0022] like Figure 1-4As shown, a sleeve 205 is symmetrically fixedly connected to the right block 3, and guide blocks 206 are installed on both sides of the left block 2. The guide blocks 206 and the sleeve 205 are slidably disposed together, and the shape of the guide blocks 206 and the shape of the sleeve 205 are mutually matched.
[0023] The effect achieved by the entire embodiment 1 is that, during use, the guide block 206 slides in the sleeve 205, which improves the overall structure of the left block 2 and the right block 3 to be in a relatively stable state during the sliding, and provides structural protection for the later extension of the frame 1 or the shortening of the frame 1 to hoist the pipe 5.
[0024] Working principle: The frame has an installation ring at the top, allowing the frame structure to work in conjunction with external hoisting tools to hoist pipes. The distance between the left and right blocks is adjusted according to the number of pipes to be hoisted, increasing the overall number of pipes that can be gripped. A hydraulic cylinder in the left block drives a sliding rod to the right. Since the end of the sliding rod is detachably connected to the limit seat on the right block, the right block moves away from the left block, increasing the relative distance between the frame and the left block. Then, workers manually thread steel cables through the bottom of the pipes to be hoisted. The motor in the right-side bracket then drives the rotor to rotate the shaft in the bracket, tightening the steel cables in the rollers of the right-side bracket until multiple sets of pipes on the steel cables are lifted, completing the pipe limiting operation. Finally, the hoisting tools are used to hoist the limited-position pipes.
