DETAILED DESCRIPTION

[0016] The specific implementation methods of the utility model are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model.

[0017] like Figure 1-4As shown, the utility model provides a horizontal pipe segment hanger, including a crossbeam 1, a connecting rod 3, a locking assembly 7 and a clamping assembly 8. The two sides of the crossbeam 1 are respectively slidably connected with a clamping frame 2. The connecting rod 3 is provided with two, and one end of each connecting rod 3 is rotatably connected to the corresponding clamping frame 2. The other ends of the two connecting rods 3 are rotatably connected through a connecting rod shaft 4. A fixing rod 5 is provided on the side of the connecting rod 3. One end of the fixing rod 5 is hinged to the connecting rod 3, and the other end of the fixing rod 5 is hinged to the crossbeam 1. The connecting rod shaft 4 is provided with a lifting ear 6. The locking assembly 7 is arranged on the connecting rod shaft 4 and is used to lock and fix the clamped pipe segment. The clamping assembly 8 is provided with two and is symmetrically arranged at the bottom of the crossbeam 1 and is used to press the pipe segment. Fixed frames 11 are symmetrically arranged at both ends of the crossbeam 1, and anti-collision wheels 12 are rotatably connected to the fixed frames 11.

[0018] It should be noted that the clamping frame 2 includes a hanging arm 22, rollers 21 and a load-bearing beam 23. The rollers 21 are provided in two rows and are rotatably connected to the upper part of the hanging arm 22. The crossbeam 1 is located between the upper and lower rows of rollers 21. The load-bearing beam 23 is located at the lower end of the hanging arm 22.

[0019] In addition, the locking assembly 7 includes a locking hook 72, a sleeve 71 and an operating handle 76. The sleeve 71 is sleeved on the connecting rod shaft 4. The locking hook 72 is arranged on the lower side of the sleeve 71 and is provided with a protruding locking portion 73. The top of the crossbeam 1 is provided with a hook rod 75 between two fixing plates 74 for hooking with the locking portion 73 after locking. The operating handle 76 is provided on the sleeve 71, and the locking hook 72 is conveniently rotated by the provided operating handle 76.

[0020] In addition, the clamping assembly 8 includes a fixed arm 81 , a support frame 82 and a pressure plate 83 . The fixed arm 81 is disposed at the bottom of the beam 1 and has support frames 82 at both ends thereof. The pressure plate 83 is rotatably connected to the lower end of the support frame 82 .

[0021] It is worth noting that the fixed frame 11 includes an end plate 111 and a side plate 112. The end plate 111 is arranged at the end of the beam 1. The two ends of the end plate 111 are respectively provided with side plates 112 inclined downward. The anti-collision wheel 12 is arranged at the lower end of the side plate 112. Through the set fixed frame and anti-collision wheel 12, the entire sling and the ground are supported by the anti-collision wheel 12 when the gravity of the sling moves downward.

[0022] Specific implementation and principle:

[0023] When the utility model is actually used, the hook of the lifting device hooks the lifting ear 6 of the lifting device and transfers the lifting device to the pipe segment to be lifted. The worker lifts up the operating handle 76, and the locking hook 72 rotates on the connecting rod shaft 4 driven by the operating handle 76. Under the action of gravity, the beam 1 falls downward. When the anti-collision wheel 12 on the fixed frame 11 contacts the ground, the whole is supported. The connecting rod 3 rotates to drive the clamping frame 2 to move on the beam 1, and the load-bearing beam 23 at the bottom of the beam 1 clamps the pipe segment. The worker releases the operating handle 76, and the locking hook 72 rotates in the opposite direction under the action of gravity. The locking part 73 of the locking hook 72 is blocked by the hook rod 75 and can no longer rotate to the other side of the hook rod 75. The fixed rod 5 is parallel to the connecting rod 3 on one side, thereby preventing the clamping frame 2 from moving on the beam 1 at the same time, and the pressure plate 83 on the fixed arm 81 presses the pipe segment.

[0024] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
