DETAILED DESCRIPTION

[0024] Please refer to the drawings in the description Figure 1 to Figure 4 The utility model discloses a hoist beam system of telegraph pole crane, which is used for adsorbing and hoisting telegraph pole 10 and is composed of hoist beam 1, stand 2, connecting base 3, suction cup device 4, folding rod 5, vacuum pump 6 and air valve 7.

[0025] The hoist beam 1 is horizontally arranged. In the embodiment, the hoist beam 1 is a hollow and closed square tube, which has simple structure, light weight compared with the I-beam of the prior art, and the inside of the hoist beam 1 can be pumped to negative pressure without additional installation of a negative pressure tank.

[0026] The stand 2 is vertically installed on the hoist beam 1, and each stand 2 is correspondingly provided with a suction cup device 4, so that two stands of the prior art are improved to a single stand, the cost of the equipment is reduced, the weight of the equipment is reduced, and the upward and downward rotation of the suction cup device 4 is facilitated to adjust the position.

[0027] Further, the upper part of each stand 2 is provided with a spring pressing cap 21; a spring I 22 is sleeved on the stand 2 and abuts between the spring pressing cap 21 and the upper surface of the hanger beam 1; the lower part of the stand 2 is provided with a spring cover 23, and a spring II 24 is sleeved on the stand 2 and abuts between the spring cover 23 and the lower surface of the hanger beam 1. The spring I 22 and the spring II 24 form a set of buffering devices which can buffer the suction cup device 4 when the suction cup device 4 abuts against the power pole 10, and each suction cup device 4 is equipped with only one set of buffering devices, so as to simplify the structure of the hanger beam system.

[0028] The connecting base 3 is pivoted to the stand 2 through a pin shaft 31, so that the connecting base 3 can rotate up and down about the pin shaft 31. The suction cup device 4 is installed on the connecting base 3 and can rotate with the connecting base 3 to adjust the position of the suction cup device 4, so as to facilitate the adhesion of the suction cup device 4 to the power pole 10 with a non-equal cross section, and make the suction force of the suction cup device 4 strong and the performance reliable.

[0029] In the embodiment, the suction cup device 4 is composed of a horizontal connecting plate 41, a lower swing seat 42 and a rubber suction cup 43. The horizontal connecting plate 41 is pivoted to the connecting base 3; the lower swing seat 42 is connected to the horizontal connecting plate 41 through a pair of buckles 44, so that the lower swing seat 42 can move relative to the connecting base 3.

[0030] The rubber suction cup 43 is installed at the bottom of the lower swing seat 42 and can adhere to the power pole 10. Specifically, the rubber suction cup 43 is installed on the lower swing seat 42 through a pair of clamping plates 45, so as to facilitate the replacement of different models of rubber suction cups 43.

[0031] The folding rod 5 is installed at one end on the hanger beam 2 and at the other end on the connecting base 3, and can be folded with the rotation of the connecting base 3 and avoid the forward and backward deflection of the connecting base 3. Specifically, the folding rod 5 is composed of a rod body I 51, a rod body II 52, a rod body III 53 and a rod body IV 54. The rod body I 51 is fixed at one end to the bottom of the hanger beam 1 and pivoted at the other end to the rod body II 52; the rod body IV 54 is fixed at one end to one side of the connecting base 3 and pivoted at the other end to the rod body III 53. The rod body II 52 is pivoted to the rod body III 53. The folding rod 5 in the above-mentioned four-bar linkage form can effectively avoid the shaking of the power pole 10 caused by the forward and backward swing of the suction cup device, and does not affect the upward and downward rotation of the suction cup device 4.

[0032] The vacuum pump 6 is installed on the beam 1, which can extract the gas in the beam 1 to generate negative pressure in the beam 1. The air valve 7 is connected between the beam 1 and the suction cup device 4 through the air pipe 71. In the embodiment, only one vacuum pump 6 is needed, which further saves the equipment cost, and each suction cup device 4 is connected to the same beam 1 through the air pipe 71. When the rubber suction cup 43 is attached to the pole 10, the air pipe 71 is connected to the rubber suction cup 43, and the air in the rubber suction cup 43 is extracted by opening the air valve 7, so that the rubber suction cup 43 is adsorbed to the pole 10.

[0033] The design principle of the beam system of the pole crane is as follows: the beam 1 adopts a hollow square tube, which is light in weight and can be used as a negative pressure tank, thereby reducing the self-weight and cost of the equipment. The gas in the beam 1 is extracted by the vacuum pump 6 to generate negative pressure in the beam 1, and only one vacuum pump 6 is needed in the process.

[0034] When the beam system adsorbs the pole 10, when the rubber suction cup 43 abuts against the pole 10, since the cross section of the pole 10 is not equal in diameter, that is, it has a certain taper, at this time, the connecting base 3 rotates around the pin shaft 31 to rotate the rubber suction cup 43 by a certain angle and tightly adhere to the pole 10. And due to the limiting effect of the folding rod 5, the connecting base 3 can only rotate up and down, and cannot sway forward and backward, so that the pole 10 is stably adsorbed. At the same time, the adjacent suction cup device 4 is adjusted in height by the extension and contraction of the spring I22 and the spring II24, so that all the suction cup devices 4 can be adsorbed on the pole 10. Finally, all the air valves 7 are opened, the air in the rubber suction cup 43 is extracted, and the rubber suction cup 43 is firmly adsorbed to the pole 10.

[0035] 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.
