[0017] Example 1

[0018] As shown in Figures 1 and 2, the present invention proposes a pipeline laying and hoisting equipment, including a counterweight 1, an extension mechanism, and a clamping mechanism. Two sets of traveling frames 102 are provided at the bottom of the counterweight 1. A lifting mechanism 104 is installed between the top of the traveling frames 102 and the bottom of the counterweight 1. The lifting mechanism 104 is a hydraulic rod. The extension mechanism is adjustablely installed at the top of the counterweight 1. The extension mechanism consists of a drive assembly installed on the counterweight 1 and two sets of movable arms 202 symmetrically installed on the drive assembly. The two sets of movable arms 202 are driven by the drive assembly to slide closer to or further away from the top of the counterweight 1. A connecting arm 203 is installed on the movable arm 202 at the end furthest from the drive assembly. Two clamping mechanisms are provided, with each clamping mechanism installed at the bottom of the corresponding connecting arm 203.

[0019] Furthermore, a shield 105 is installed on the top of the counterweight seat 1. The shield 105 is used to protect the drive components at the top of the counterweight seat 1 from being damaged by external interference. Two sets of handles 103 are symmetrically installed on the side wall of the counterweight seat 1, which makes it easy for workers to push the entire equipment through the handles 103 without interfering with the hoisting of the pipeline.

[0020] Furthermore, the top of the counterweight 1 is provided with a mounting groove 101, and the end of the moving arm 202 away from the clamping mechanism is slidably connected to the mounting groove 101. The drive component is disposed inside the mounting groove 101.

[0021] Furthermore, the drive assembly consists of a drive component 2 and two sets of lead screws 201. The drive component 2 is a dual-axis motor. The drive component 2 is installed in the middle of the mounting groove 101. The two sets of lead screws 201 are respectively connected to the two output ends of the drive component 2. The other ends of the two sets of lead screws 201 are respectively rotatably connected to the two ends of the mounting groove 101.

[0022] In this embodiment, pushing the handle 103 moves the device to a suitable position via the two sets of traveling frames 102, so that the pipe to be hoisted is located between the two sets of traveling frames 102. The controller starts the drive unit 2 to drive the two sets of lead screws 201 to rotate, thereby driving the two sets of moving arms 202 to slide closer to or further away from the mounting groove 101 to adjust to a suitable position, so that the two sets of clamping mechanisms are adapted to the length of the pipe. When the length of the pipe to be hoisted changes, it can be adjusted in this way to make the two sets of clamping mechanisms adapt to pipes of different lengths, improve the stability of clamping and hoisting, and avoid falling off. The controller starts the lifting mechanism 104 to drive the counterweight 1 to move downward along the two sets of traveling frames 102 until the two sets of clamping mechanisms move down to a suitable height. The controller starts the two sets of clamping mechanisms to clamp both ends of the pipe. Restarting the lifting mechanism 104 causes the counterweight 1 to move upward along the traveling frame 102. At this time, the pipe can be moved away from the ground by the two sets of clamping mechanisms, and the handle 103 can be pushed to transport the pipe stably.

[0023] Example 2

[0024] As shown in Figures 1 and 3, the pipe laying and hoisting equipment proposed in this utility model, compared with Embodiment 1, includes a clamping mechanism comprising a connecting seat 3, a clamping arm, and a telescopic member 405; the connecting seat 3 is installed at the bottom end of the connecting arm 203, and the cross-section of the connecting seat 3 is U-shaped; the clamping arm is adjustablely connected inside the connecting seat 3; two sets of telescopic members 405 are provided, and the telescopic members 405 are hydraulic rods, and the two sets of telescopic members 405 are respectively hinged to both sides of the inner wall of the top of the connecting seat 3, and the other end of the two sets of telescopic members 405 are hinged to the corresponding position of the clamping arm.

[0025] Furthermore, a connecting shaft 301 is installed on the inner wall of the connecting seat 3. The clamping arm is composed of a first rotating seat 4, a first clamping part 401, a second rotating seat 402, and a second clamping part 403. The first rotating seat 4 and the second rotating seat 402 are rotatably connected to the connecting shaft 301. The first clamping part 401 and the second clamping part 403 are respectively installed at the bottom ends of the first rotating seat 4 and the second rotating seat 402. Anti-slip pads 406 are provided on the clamping ends of the inner walls of the first clamping part 401 and the second clamping part 403 to increase the friction at the connection with the side wall of the pipe, prevent the pipe from slipping, and improve the stability of the hoisting. The ends of the two sets of telescopic members 405 away from the connecting seat 3 are respectively hinged to the first rotating seat 4 and the second rotating seat 402. The side walls of the first rotating seat 4 and the second rotating seat 402 and the top of the connecting seat 3 are all provided with hinge seats 404 corresponding to the telescopic members 405.

[0026] In this embodiment, the controller activates the retraction of the output ends of the two sets of telescopic components 405, thereby causing the first rotating seat 4 and the second rotating seat 402 to rotate along the connecting seat 3. This, in turn, causes the first clamping part 401 and the second clamping part 403 to rotate away. The retraction of the output end of the lifting mechanism 104, along with the counterweight 1, causes the clamping arm to move downwards until the pipe is positioned between the first clamping part 401 and the second clamping part 403. The controller then activates the two sets of telescopic components 405 to extend their output ends, causing the first clamping part 401 and the second clamping part 403 to rotate closer together until the pipe is clamped. The two clamping mechanisms can stably clamp both ends of the pipe, adapting to the lifting of pipes of different sizes, offering a wide range of applications and more stable lifting.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
