[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer according to the following description and claims. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0030] like Figure 1 and Figure 3 As shown, this embodiment provides a portable lifting equipment, including a coupling 1, a boom 2 and a lifting member 3, one end of the boom 2 is connected to the coupling 1, and the lifting member 3 is arranged at the other end of the boom 2, and the coupling 1 is used to be coupled to a carrier 4, and has a simple structure and a small size, so that the hanging member can be directly coupled to the carrier, and the entire boom is in a suspended state, and the lifting member can perform lifting operations at the other end of the boom. Preferably, the carrier 4 is a rod or a pipe, and has good operating flexibility; further preferably, the carrier 4 is a pipe horizontally suspended, and has good operating convenience, and can be directly installed on the suspended pipe and used as a lifting platform for lifting operations.

[0031] In actual operation, there may be multiple suspended pipes arranged side by side, and together they form a space for people to stand. At this time, the outermost pipe is selected as a carrier for the installation of the coupling. In the process of adding pipes, the object to be lifted is a pipe. At this time, at least two portable lifting devices such as those provided in this embodiment can be used for synchronous lifting. For example, the two portable lifting devices can be arranged at intervals along the length direction of the carrier, and the two lifting parts can respectively hang the pipe to be lifted, so as to lift the pipe to be lifted above the carrier.

[0032] Among them, the pipe selected as the carrier must have a good load-bearing capacity, and it must be able to accommodate people standing on top.

[0033] like Figure 1 and Figure 4As shown, the end of the boom 2 in the above technical solution away from the hoop connector 1 is bent, so that the lifting member can extend through the bend of the boom to the periphery of the carrier for operation. It should be noted that there is only one bend on the boom (i.e., a corner is formed at the bend). The boom 2 is preferably made of a light and high-strength material (such as an aluminum alloy). In order to improve the bending resistance of the entire boom 2, a reinforcing rod 22 can be added to the inner side of the bend of the boom 2 in this embodiment. The two ends of the reinforcing rod 22 are respectively connected to the middle of the two ends of the bend of the boom. At this time, the reinforcing rod and the boom together form a triangle, and the reinforcing rod can improve the supporting performance of the bend of the boom.

[0034] The bending angle of the bending part of the boom 2 in the above technical solution is 90°-150°, and the structure is simple.

[0035] In the above technical solution, the end of the boom 2 away from the hoop connector 1 is provided with a hanging ring 21, so that the lifting member can be connected to the boom more conveniently.

[0036] The lifting member 3 in the above technical solution is a lifting traction hoist, and the upper end of the lifting member 3 has a hook 31 and a sling 32. The hook 31 is used to be hung with the hanging ring 21, and the sling 32 is used to lift objects. It has a simple structure and is easy to operate.

[0037] The lifting and traction hoist is a prior art and will not be described in detail here. The lifting member can be an electric lifting and traction hoist, which saves effort in operation and is easy to control.

[0038] The coupling member 1 in the above technical solution includes two arc-shaped coupling plates 11, and the corresponding end of the boom 2 is connected to the side of any one of the coupling plates 11 away from its notch, and the two coupling plates 11 are used to be clamped on the carrier 4 together, so that the coupling member can be conveniently clamped on the carrier through the two coupling plates. Among them, the two coupling plates are both semicircular ring plates, and the coupling member can be an existing pipe coupling member, which belongs to the prior art and is not described here (the two ends of the two coupling plates can be bolted together by bolts and nuts after being aligned).

[0039] like Figure 2 As shown, in the above technical solution, a reinforcing plate 12 is provided at the connection between the boom 2 and the hoop plate 11, so that the connection between the boom and the corresponding hoop plate is more firmly established, the reinforcing plate 12 is a right-angled triangular plate, and a plurality of reinforcing plates can be provided, and a plurality of the reinforcing plates are distributed in a ring-shaped interval at the corresponding ends of the boom, and the two straight sides of each reinforcing plate are respectively welded to the boom and the hoop plate, and the corresponding end of the boom can also be welded to the corresponding hoop plate.

[0040] like Figure 2 As shown, in the above technical solution, an anti-skid pad 13 is provided on the inner side of the arc of the hoop plate 11. Such a suitable hoop member is not easy to loosen after the carrier is hooped. The anti-skid pad can be a rubber pad (similar to a tire skin, which is attached to the inner side of the arc of the hoop plate). The inner side of the arc of the anti-skid pad should be a friction surface (such as covered with grooves to increase the friction between the anti-skid pad and the carrier).

[0041] In this embodiment, the plane where the suspension arm is located is perpendicular to the carrier, that is, the end of the suspension arm away from the hoop connector is bent to the side of the carrier.
