[0025] Through the anti-collision mechanism 6, the electric hoist can contact the anti-collision plate 65 so that it will not contact the support seat 4, thereby achieving an anti-collision effect, making the support seat 4 not easily damaged, and thus convenient for people to use.

[0026] like Figure 3 As shown, the lifting assembly 2 includes a support tube 21, the lower end of the support tube 21 is fixedly connected to the upper end of the support plate 1, a motor 22 is fixedly installed at the inner bottom end of the support tube 21, the output end of the motor 22 is transmission-connected with a screw rod 23, the outer surface of the screw rod 23 is sleeved with a lifting column 24 connected by a thread, and the left and right inner walls of the support tube 21 are symmetrically provided with limit grooves 25, and the inner sliding connection of the limit grooves 25 is limited Block 26.

[0027] The top of the lifting column 24 extends out of the support tube 21 , and the top of the lifting column 24 is fixedly connected to the lower end of the support seat 4 .

[0028] The bottom end of the limit block 26 is fixedly connected to the left and right sides of the lower end of the lifting column 24 .

[0029] When the lifting column 24 moves up and down, the limiting block 26 is driven to slide synchronously inside the limiting groove 25, thereby preventing the lifting column 24 from rotating.

The rubber pad set on the anti-collision plate 65 can protect the anti-collision plate 65 and prevent it from being damaged.

[0034] The following is a detailed description of the working principle of the electric hoist gantry crane with anti-collision protection device.

[0035] like Figure 1-4 As shown, when the electric hoist gantry crane with anti-collision protection device is in use, first, the wire rope 14 can be fixed to the cargo through the lifting hook 16, and then the motor 17 can be started, and the motor 17 can drive the winding roller 13 to rotate forward and reverse, so that the wire rope 14 can be wound or extended, and then the trolley can be moved horizontally left and right on the crossbeam 5, and at the same time, the slider 10 and the slider 2 11 can be driven to slide in the slide groove 1 8 and the slide groove 2 9 respectively, so as to improve the stability of the trolley when moving. When the trolley moves, the cargo can be moved together through the lifting hook 16, and the motor 22 can be started, and the motor 22 drives the screw 23 to rotate, so that The screw 23 drives the threaded lifting column 24 to move up and down, so that the lifting column 24 can drive the crossbeam 5 to move synchronously through the support seat 4, so that the height can be adjusted, and the crane can adjust the goods to different positions. When the trolley drives the installation box 12 to move synchronously, the installation box 12 will contact the anti-collision plate 65, so that the anti-collision plate 65 pushes the pillar 64 to move outward, so that the pillar 64 drives the limit plate 63 to move, so that the limit plate 63 will compress the spring 62, causing the spring 62 to deform, and the deformation of the spring 62 will buffer the collision impact force generated during the movement, thereby achieving the effect of protecting the support seat 4.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
