[0038] It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other; the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

They are not intended to indicate or imply that the indicated positions or components must have a specific orientation, be constructed, or operate in a specific orientation, and are therefore not to be construed as limitations of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

[0040] Reference Figure 1-10 The present invention proposes a crane for stably lifting a substation structure A. The substation structure A includes a main pipe A1 and multiple cross arms A2 arranged on the main pipe A1. The crane includes: a car body 1, a winch 2, a lifting arm 3, a support wheel 5, a cylinder 4, a rope 6, a sling 7, and a clamping part.

[0041] The winch 2 is arranged on the vehicle body 1; the lifting arm 3 is movably arranged on the vehicle body 1; the oil cylinder 4 is arranged on the vehicle body 1, and the output end of the oil cylinder 4 is connected to the lifting arm 3; the support wheel 5 is installed at the top end of the lifting arm 3; the first end of the rope 6 passes around the support wheel 5 and is connected to the winch 2; the sling 7 is connected to the second end of the rope 6; the clamping part includes a support plate 8 and a first clamp 9, the first clamp 9 is used to clamp the main pipe A1, and the first clamp 9 is arranged under one of the crossarms A2 when in use; the support plate 8 is connected to the first clamp 9, the support plate 8 is used to abut against the crossarm A2, and the support plate 8 is connected to the sling 7.

[0042] Combine Figure 2 , place the first clamp 9 under the topmost cross arm A2, and let the first clamp 9 clamp the main pipe A1. Let the support plate 8 abut against the cross arm A2.

[0043] Connect the support plate 8 to the sling 7, use the winch 2 to retract the rope 6, and gradually lift the substation structure A. By moving the vehicle body 1 and the crane arm, it can be installed in the appropriate position.

[0044] This embodiment features a specially designed clamping mechanism tailored to the specific structure of the substation support A. A first clamp 9 is provided to clamp the main pipe A1. By abutting the support plate 8 against the crossarm A2 and applying force to both the main pipe A1 and the crossarm A2, the clamping mechanism effectively prevents accidental detachment of the substation support A from the clamping mechanism, allowing for efficient, stable, and safe lifting of the substation support A.

[0045] When hoisting, the existing crane generally directly wraps the rope 6 around the crossarm A2. Since the crossarm A2 is welded to the main pipe A1, excessive force on the crossarm A2 may cause the crossarm A2 and the main pipe A1 to break, causing a safety hazard.

[0046] As a further improvement of the above embodiment, in one embodiment, the first clamp 9 includes two first clamping plates 901 arranged opposite to each other and a first fastener 902 for fixing the two first clamping plates 901. Figure 3 The two first clamping plates 901 are placed on both sides of the main pipe A1 and then brought close together. The two first clamping plates 901 are fixed with the first fasteners 902 to clamp and fix the main pipe A1. The first fasteners 902 can be bolts, and the two first clamping plates 901 are fixed with the bolts.

[0047] As a further improvement to the above embodiment, in one embodiment, the first clamping plate 901 has a first curved surface 9011 that matches the main pipe A1. The first curved surface 9011 better fits the main pipe A1, increases friction, and prevents movement along the length of the main pipe A1, which could cause safety hazards.

[0048] As a further improvement to the above embodiment, in one embodiment, the support plate 8 is provided with a receiving groove 801 for accommodating the crossarm A2. Placing the crossarm A2 in the receiving groove 801 prevents the crossarm A2 from circumferentially moving along the main pipe A1, and also prevents the first clamp 9 from moving along the length of the main pipe A1. This prevents the substation support A from swaying along the circumferential direction of the main pipe A1 relative to the support plate 8 during lifting, thus avoiding potential safety hazards.

[0049] As a further improvement of the above embodiment, in one embodiment, the crane further comprises: a first connecting member 10, wherein:

[0050] There are multiple clamping parts, and the multiple clamping parts are sequentially spaced apart along the length direction of the main pipe A1 , and any two adjacent clamping parts are connected by the first connecting member 10 .

[0051] In order to further ensure the connection security, multiple clamping parts are provided, combined with Figure 3 , allowing the upper support plate 8 to connect with the sling 7, and multiple clamping parts to be connected in sequence, to avoid the safety hazard caused by the cross arm A2 being broken due to excessive force, thereby improving the connection safety.

[0052] As a further improvement to the above embodiment, in one embodiment, the first connector 10 includes a first threaded tube 1001 and a first threaded rod 1002 threadedly connected to the first threaded tube 1001. One of the first threaded tube 1001 and the first threaded rod 1002 is connected to one support plate 8, while the other is rotatably connected to the other support plate 8. In this embodiment, the first threaded rod 1002 is connected to one support plate 8, while the first threaded tube 1001 is rotatably connected to the other support plate 8. The spacing between adjacent crossarms A2 can be adjusted by rotating the first threaded tube 1001, providing excellent adaptability.

[0053] As a further improvement of the above embodiment, in one embodiment, the crane further includes a second clamp 11 and a second connecting member 12, wherein the second clamp 11 is used to clamp the lower part of the main pipe A1, and the second clamp 11 is connected to the car body 1 or the lifting arm 3 through the second connecting member 12, and is connected to the car body 1 in this embodiment.

[0054] Combine Figure 2 、 8 , 9, it can be understood that the substation structure support A is generally placed on the ground. The first clamp 9 is used to clamp the upper part of the substation structure support A. If the second clamp 11 and the second connecting member 12 are not provided. Then during the lifting process, as the upper part of the substation structure support A continues to rise, the bottom end of the substation structure support A may slide on the ground, causing a safety hazard. Therefore, this embodiment provides a second clamp 11, connects it to the lower part of the main pipe A1, and connects it to the vehicle body 1 through the second connecting member 12. In this way, during lifting, the bottom end of the substation structure support A is prevented from sliding on the ground, thereby avoiding safety hazards and effectively achieving smooth and safe lifting.

[0055] Moreover, after the substation support A is completely off the ground, the bottom end of the main pipe A1 is restrained by the second clamp 11, which effectively prevents the bottom end of the main pipe A1 from shaking during the lifting process, thereby avoiding potential safety hazards.

[0056] As a further improvement to the above embodiment, in one embodiment, the second clamp 11 includes two opposing second clamping plates 111 and a second fastener 112 for securing the two second clamping plates 111. The second clamping plates 111 are connected to the vehicle body 1 or the lifting arm 3 via the second connecting member 12. The second fastener 112 can be a bolt. The second clamping plates 111 are placed on either side of the main pipe A1 and secured together with bolts to effectively secure the main pipe A1.

[0057] The first clamp 9, the second clamp 11 and the second connection are arranged to cooperate with each other to prevent the bottom end of the main pipe A1 from sliding on the ground when starting to lift, and to prevent the bottom end of the main pipe A1 from swinging during the lifting process, thereby effectively achieving smooth and safe lifting.

[0058] As a further improvement to the above embodiment, in one embodiment, the second connector 12 includes a second threaded tube 121 and a second threaded rod 122 threadedly connected to the second threaded tube 121. One of the second threaded tube 121 and the second threaded rod 122 is connected to the second clamping plate 111, while the other is connected to the vehicle body 1 or the lifting arm 3. This embodiment allows the second threaded rod 122 to be rotatably connected to the second clamping plate 111, allowing the second threaded tube 121 to be connected to the vehicle body 1, and the second threaded tube 121 can only rotate in the vertical plane. The second clamping plate 111 has a second curved surface that mates with the main pipe A1, thereby better clamping the main pipe A1.

[0059] It can be understood that the substation structure support A is placed on the ground at the beginning. During the lifting process, the substation structure support A is vertical. Therefore, by allowing the second clamping plate 111 to rotate relative to the second threaded rod 122, the second clamping plate 111 can rotate with the substation structure support A to better clamp the main pipe A1.

[0060] At the start of the lift, the substation support A is placed on the ground, with the second clamp 11 very close to the ground. As the lift progresses, the substation support A rises and gradually becomes vertical, causing the position of the second clamp 11 to continuously change. Therefore, allowing the second threaded tube 121 to rotate only in the vertical plane satisfies the needs of the second clamp 11 and prevents horizontal swinging of the second clamp 11, which could pose a safety hazard.

[0061] After hoisting to a suitable position, first remove the second clamp 11, and after installing the bottom end of the main pipe A1, remove the first clamp 9. Easy to use.

[0062] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
