[0032] Among them, the trolley running track 1 is erected on both sides of crane. Bridge 2 is installed with roller 21 on both sides, and roller 21 supports and can move along trolley running track 1.

[0033] Lifting trolley 3 is supported on bridge 2, and can move along the extension direction of bridge 2, to adjust lifting position. Bridge 2, lifting trolley 4 are prior art, so, here will not repeat.

[0034] Lifting beam 4 is connected to the bottom of lifting trolley 3, and is driven by lifting trolley 3 to lift, so as to realize the lifting of electric pole 10. Lifting beam 4 is horizontally arranged. In the embodiment, the lifting beam 4 is a hollow and closed square tube, which has simple structure, light weight compared with the existing technology of H-shaped steel beam, and the inside of lifting beam 4 can be pumped into negative pressure, without additional installation of negative pressure tank.

[0035] Further, the two ends of the bottom of the lifting beam 4 are respectively provided with a telescopic positioning frame 41, which can abut on electric pole 10, so as to position electric pole 10.

[0036] The stand column 5 is vertically installed on the lifting beam 4, and in the embodiment, the stand column 5 is provided with a plurality of equal intervals, and each stand column 5 is correspondingly provided with a suction cup device 7, so that the two stand columns of the prior art are improved to a single stand column, the cost of the equipment is reduced, the self weight of the equipment is reduced, and the suction cup device 7 is conveniently rotated up and down to adjust the position.

[0037] Further, the upper part of each stand column 5 is provided with a spring pressing cap 51; a spring I 52 is sleeved on the stand column 5 and abuts between the spring pressing cap 51 and the upper surface of the lifting beam 4; the lower part of the stand column 5 is provided with a spring cover 53, and a spring II 54 is sleeved on the stand column 5 and abuts between the spring cover 53 and the lower surface of the lifting beam 4. The spring I 52 and the spring II 54 form a set of buffer devices, which can buffer the suction cup device 7 when the suction cup device 7 abuts on the electric pole 10, and each suction cup device 7 is only equipped with a set of buffer devices, so that the structure of the lifting beam system is simplified.

[0038] The connecting base 6 is pivoted to the stand 5 through a pin shaft 61, so that the connecting base 6 can rotate up and down around the pin shaft 61. The suction cup device 7 is installed on the connecting base 6, and can rotate with the connecting base 6 to adjust the position of the suction cup device 7, so that the suction cup device 7 can be attached to the non-equal-section pole 10, and the suction force of the suction cup device 7 is strong and reliable.

[0039] In the embodiment, the suction cup device 7 is composed of a horizontal connecting plate 71, a lower swing seat 72 and a rubber suction cup 73. The horizontal connecting plate 71 is pivoted to the connecting base 6, and the lower swing seat 72 is connected to the horizontal connecting plate 71 through a pair of buckles 74, so that the lower swing seat 72 can move relative to the connecting base 6.

[0040] The rubber suction cup 73 is installed at the bottom of the lower swing seat 72, and can be attached to the pole 10. Specifically, the rubber suction cup 73 is installed on the lower swing seat 72 through a pair of clamping plates 75, so that different types of rubber suction cups 73 can be replaced.

[0041] Further, a set of folding rods 9 is installed between the hanging beam 4 and the connecting base 6, which can be folded with the rotation of the connecting base 6, and avoid the front and rear deflection of the connecting base 6. Specifically, the folding rod 9 is composed of a rod body I 91, a rod body II 92, a rod body III 93 and a rod body IV 94. One end of the rod body I 91 is fixed to the bottom of the hanging beam 4, and the other end is pivoted to the rod body II 92. One end of the rod body IV 94 is fixed to one side of the connecting base 6, and the other end is pivoted to the rod body III 93. The rod body II 92 is pivoted to the rod body III 93. The four-bar folding rod 9 can effectively avoid the front and rear swing of the suction cup device 7 to cause the pole 10 to shake, and does not affect the up and down rotation of the suction cup device 7.

[0042] The vacuum pump 8 is installed on the hanging beam 4, which can extract the gas in the hanging beam 4 to generate negative pressure in the hanging beam 4. The gas valve 81 is connected to the hanging beam 4 and the suction cup device 7 through the air pipe 82. In the embodiment, only one vacuum pump 8 is needed, which further saves the equipment cost. Each suction cup device 7 is connected to the same hanging beam 4 through the air pipe 82. When the rubber suction cup 73 is attached to the pole 10, the air pipe 82 is connected to the rubber suction cup 73, and the air in the rubber suction cup 73 is extracted by opening the gas valve 81, so that the rubber suction cup 73 can adsorb the pole 10.

[0043] The design principle of the pole crane is as follows: the hanging beam 4 is a hollow square tube, which is light in weight and can be used as a negative pressure tank, reducing the self-weight and cost of the equipment. The gas in the hanging beam 4 is extracted by the vacuum pump 8 to generate negative pressure in the hanging beam 4, and only one vacuum pump 8 is needed in the process.

[0044] When the rubber suction cup 73 abuts against the power pole 10, the connecting base 6 rotates around the pin shaft 61, so that the rubber suction cup 73 rotates by a certain angle and tightly adheres to the power pole 10, because the power pole 10 has a taper cross section. Due to the limiting effect of the folding rod 9, the connecting base 6 can only rotate up and down, and cannot sway forward and backward, so that the power pole 10 is stably adsorbed. At the same time, the adjacent suction cup device 7 realizes height adjustment through the expansion and contraction of the spring I 52 and the spring II 54, so that all the suction cup devices 7 can be adsorbed on the power pole 10. Finally, all the air valves 81 are opened, and the air in the rubber suction cup 73 is extracted, so that the rubber suction cup 73 is firmly adsorbed on the power pole 10.

[0045] The method for the power pole crane to hoist the power pole 10 is as follows:

[0046] 1) Move the bridge 2 and the lifting trolley 3 on the bridge 2, so that the hoisting beam 4 is located above the power pole 10;

[0047] 2) The lifting trolley 3 drives the hoisting beam 4 to descend, so that the suction cup device 7 at the bottom of the hoisting beam 4 abuts against the power pole 10;

[0048] 3) The suction cup device 7 rotates around the pin shaft 61, so that each suction cup device 7 tightly adheres to the power pole 10;

[0049] 4) The vacuum pump 8 extracts the air in the hoisting beam 4, so that negative pressure is generated in the hoisting beam 4; at the same time, the air in the rubber suction cup 73 is extracted by opening the air valve 81, so that the rubber suction cup 73 is firmly adsorbed on the power pole 10;

[0050] 5) The lifting trolley 3 and the moving bridge 2 are linked to convey the power pole 10 to the required position.

[0051] The above specific embodiments are only the preferred embodiments of the present application, and are not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
