[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] See attached document Figure 1-3 It includes at least two sets of suspension brackets and a lifting mechanism. The suspension brackets are movably installed on a square steel frame. During the adjustment of the pipe direction, the suspension brackets can rotate to facilitate the adjustment of the pipe in the horizontal plane. The lifting mechanism is installed on the suspension brackets and is used to lift the pipe to a certain height.

[0023] In one embodiment of this utility model, the suspension frame includes a support rod 10, a hanging plate 11, and an auxiliary rotation assembly; the bottom end of the support rod 10 is inserted into a pipe hole in the square steel frame; wherein, as... Figure 1As shown, in the prior art, the square steel frame is composed of multiple hollow square tubes connected together. The aforementioned tube holes are the hollow positions inside the square tubes. When in use, the support rod 10 is inserted into the square tube.

[0024] The hanging plate 11 is fixedly connected to the top side wall of the support rod 10, and the hanging plate 11 is provided with a hanging hole 12.

[0025] In one embodiment of this utility model, a reinforcing plate 13 is installed between the outer wall of the hanging plate 11 and the outer wall of the support rod 10; wherein, since the hanging plate 11 is the stress-bearing part during the hoisting process, the reinforcing plate 13 can be used to strengthen the installation between the hanging plate 11 and the support rod 10.

[0026] An auxiliary rotation assembly is installed on the support rod 10 to assist the rotation of the support rod 10 relative to the square steel frame during operation; the auxiliary rotation assembly can be used to improve the smoothness of the rotation of the support rod 10 on the square steel frame.

[0027] like Figure 2 and Figure 3 As shown, in one embodiment of this utility model, the auxiliary rotation assembly includes a limiting plate 20, a planar thrust bearing 21, and a base plate 22 (the outer diameter of the base plate 22 is larger than the cross-sectional area of ​​the top of the square tube). The limiting plate 20 is installed on the outer wall of the support rod 10, and the planar thrust bearing 21 is sleeved and installed on the outside of the support rod 10. The base plate 22 is sleeved and installed on the outside of the support rod 10. When the support rod 10 is inserted into the square steel tube, the base plate 22 contacts the square steel tube. During the process of lifting the pipe, the support rod 10 will be pulled by the gravity of the pipe, so the base plate 22 will press against the top wall of the square tube. Since the planar thrust bearing 21 is provided, the upper and lower surfaces of the planar thrust bearing 21 can rotate independently. The upper surface of the planar thrust bearing 21 contacts the outer wall of the limiting plate 20, and the lower surface of the planar thrust bearing 21 contacts the outer wall of the base plate 22. Therefore, the support rod 10 can rotate.

[0028] like Figure 1 As shown, in one embodiment of this utility model, the lifting mechanism includes a hand chain hoist 30 and a suspension collar 31. The fixed hook on the top of the hand chain hoist 30 is attached to the hanging hole 12, and the suspension collar 31 is installed on the lifting hook of the hand chain hoist 30 and is sleeved on the pipe. The fixed hook on the hand chain hoist 30 is a hook used for suspending the hand chain hoist, and the lifting hook is a hook used for connecting the lifting device.

[0029] In this embodiment, the working principle of this device is as follows: when using this device to assist in the hoisting of the pipe, firstly, insert the two support rods 10 into the top opening of the square pipe, then hang the fixed hook of the hand chain hoist on the hanging hole 12, then put the two suspension collars 31 on the outside of the pipe, and then hang the lifting hook on the hand chain hoist on the suspension collar 31.

[0030] The following combination Figure 1 Description of pipe hoisting: After the installation of the device is completed, the pipe can be hoisted by operating two hand chain hoists. During the hoisting process, the worker can first rotate and adjust the direction of the left end of the pipe so that the left end of the pipe enters the inside of the square steel frame first.

[0031] Then push the right end of the pipe horizontally and adjust the relative position between the right end of the pipe and the right side suspension collar 31. This step is to facilitate the right end of the pipe to smoothly enter the inside of the square steel frame. Then rotate the pipe to adjust the direction of the right end of the pipe so that the right end of the pipe enters the inside of the square steel frame.

[0032] This device is easy to operate, eliminating the need for manual lifting of pipes, thus saving manpower and improving pipe installation efficiency.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
