[0017] Figure 2 is Figure 1 the sectional view of A-A in FIG.

[0018] Figure 3 is the state view of the vacuum chuck device of the utility model's electric pole crane when adsorbing the electric pole. DETAILED DESCRIPTION

[0019] Please refer to the drawings in the description Figure 1 to the drawings Figure 3 , the utility model discloses a kind of vacuum chuck device of electric pole crane, it is used to adsorb electric pole 10, especially suitable for adsorbing non-equal-section electric pole 10.

[0020] The vacuum chuck device of the crane of the utility model is installed on a hanger beam 1, which is composed of a plurality of parts such as a stand 2, a connecting base 3, a pin shaft 4, a horizontal connecting plate 5, a lower swing seat 6, a rubber chuck 7 and a folding rod 8.

[0021] Among them, the hanger beam 1 is a hollow and closed square tube, which has a simple structure, a reduced self-weight compared to the I-beam of the prior art, and the inside of the hanger beam 1 can be pumped to negative pressure without the need for additional installation of a negative pressure tank.

[0022] The stand 2 is vertically installed on the hanger beam 1 and is provided with one, which reduces the cost of the equipment by improving the two stands of the prior art into a single stand, reduces the self-weight of the equipment, and facilitates the up and down rotation of the vacuum chuck device of the utility model.

[0023] The upper part of the stand 2 is provided with a spring pressure cap 21; a spring I 22 is sleeved on the stand 2 and abuts between the spring pressure 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 play a buffering role when the vacuum chuck device abuts on the electric pole 10.

[0024] The connecting base 3 is pivoted on the stand 2 through the pin shaft 4, so that the connecting base 3 can rotate up and down around the pin shaft 4 to adjust the position of the vacuum chuck device, so as to facilitate the chuck 7 to fit the non-equal-section electric pole 10, so that the adsorption force of the vacuum chuck device is strong and the performance is reliable.

[0025] The horizontal connecting plate 5 is pivoted to the connecting base 3; the lower swing base 6 is connected to the horizontal connecting plate 5 through a pair of buckles 61, so that the lower swing base 6 can move relative to the connecting base 3.

[0026] The rubber suction disc 7 is installed at the bottom of the lower swing base 6 and can be attached to the electric pole 10. In the embodiment, the rubber suction disc 7 is installed to the lower swing base 6 through a pair of clamping plates 71, so as to facilitate replacement of different types of rubber suction discs 7. The rubber suction disc 7 is connected with a vacuum pipe 72, and when the rubber suction disc 7 is attached to the electric pole 10, air in the rubber suction disc 7 is removed through the vacuum pipe 72, so that the rubber suction disc 7 is adsorbed to the electric pole 10.

[0027] The folding rod 8 is installed at one end of the hanging beam 2 and at the other end of the connecting base 3, and can be folded with the rotation of the connecting base 3 and avoid the front and back deflection of the connecting base 3. Specifically, the folding rod 8 is composed of a rod body I 81, a rod body II 82, a rod body III 83 and a rod body IV 84. One end of the rod body I 81 is fixed to the bottom of the hanging beam 1, and the other end is pivoted to the rod body II 82; one end of the rod body IV 84 is fixed to one side of the connecting base 3, and the other end is pivoted to the rod body III 83. The rod body II 82 and the rod body III 83 are pivoted. The folding rod 8 in the above four-bar linkage form can effectively avoid the shaking of the electric pole 10 caused by the front and back swing of the suction disc device, and does not affect the up and down rotation of the suction disc device.

[0028] As shown in the description Figure 3 The working principle of the vacuum suction disc device of the electric pole crane of the utility model is as follows: when the rubber suction disc 7 abuts against the electric pole 10, since the cross section of the electric pole 10 is not equal in diameter, i.e. has a certain taper, at this time the connecting base 3 rotates around the pin shaft 4, so that the rubber suction disc 7 rotates by a certain angle and tightly abuts against the electric pole 10. And due to the limiting effect of the folding rod 8, the connecting base 3 can only rotate up and down, and cannot swing front and back, so that the electric pole 10 is stably adsorbed. At the same time, the adjacent vacuum suction disc devices are adjusted in height through the extension and contraction of the spring I 22 and the spring II 24, so that all the vacuum suction disc devices can be adsorbed to the electric pole 10. Finally, air in the rubber suction disc 7 is removed through the vacuum pipe 72, so that the rubber suction disc 7 is firmly adsorbed to the electric pole 10.

[0029] The above specific embodiments are only the preferred embodiments of the present application, and are not used to limit the present application. 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.
