The following are also provided on the mobile lift main body 100:

[0026] An extension mechanism, and the extension mechanism includes an extension component, a moving and adjusting component and a supporting and sliding component. The extension component is arranged at both ends of the upper surface of the lifting plate 103. The moving and adjusting component is arranged at the middle position inside the lifting plate 103. The supporting and sliding component is arranged at both ends of the extension component. When the mobile lift main body 100 is installed on the equipment and lifted to a certain height, when lifting a wider equipment, the extension mechanism can increase the supporting area of the lifting plate 103, increase the contact area and lift and place more stably, so as to improve the stability of the mobile lift main body 100 when lifting and installing a wider equipment.

[0027] In order to facilitate increasing the supporting area of the lifting plate 103 through the extension component, and facilitate increasing the contact area and stably lifting and installing when installing a wider equipment. In this embodiment, preferably, the extension component includes adjustment grooves 1032 opened on both sides of the upper surface of the lifting plate 103. An extension plate 1031 is arranged inside the adjustment grooves 1032. Two fixing bolts II 1035 are rotatably connected to both ends of the upper surface of the extension plate 1031.

When the extension plate 1031 is subjected to gravity, it is not easy to shake, thereby improving the stability of the extension and opening support of the extension plate 1031 when the mobile lifting machine main body 100 is lifted to a certain height for installation operation, and making the installation operation more stable.

[0031] In order to facilitate the limiting opening or closing of the moving plate 1011 through the sliding connection component and facilitate adjustment and use, in this embodiment, preferably, the sliding connection component includes limiting moving grooves 1013 opened at both end parts of the main frame 101.

Fixing bolts 1015 are screwed and connected to both end parts of the upper surface of the main frame 101. After the moving plate 1011 is opened, the fixing bolts 1015 are rotated to fix the end part of the moving plate 1011 inside the main frame 101.

[0032] In order to facilitate the supporting operation of the extension plate 1031 after it is extended and opened through the supporting and fixing component, in this embodiment, preferably, the supporting and fixing component includes an inner threaded rod 1017 fixedly installed inside the moving plate 1011 through a connecting pin.

A supporting leg 1012 is rotatably connected to the lower surface of one end of the moving plate 1011. After the moving plate 1011 is opened, the bottom end of the supporting leg 1012 is rotated to contact the ground to support the moving plate 1011, facilitating the stable supporting operation.

[0033] In order to facilitate the clamping installation of the top end of the outer threaded rod 1016 and the lower surface of the extension plate 1031 through the clamping component, in this embodiment, preferably, the clamping component includes a clamping groove 1019 arranged at the top end of the outer threaded rod 1016.

The outer threaded rod 1016 can be rotated to clamp the end part of the clamping head 1018 inside the clamping groove 1019 to support the extension plate 1031.

[0034] The working principle and usage process of the present utility model: When using this kind of mobile lift, the mobile lift main body 100 is stably moved to the lifting and installation position by the moving wheels 102 contacting the ground. The equipment to be installed is placed on the surface of the lifting plate 103, and the two groups of driving mechanisms 105 operate simultaneously to drive the lifting frame 104 to rise and adjust the lifting plate 103 to the installation height, so that the equipment is at the installation height. Therefore, it is convenient to lift the equipment to the installation position and move it to the fixed installation position.

[0035] Then, when the mobile lifting machine body 100 is lifting and installing the equipment, when lifting and installing a wider equipment, the rotating wheel 1038 can be rotated to drive the bidirectional lead screw 1037 to rotate. When the bidirectional lead screw 1037 rotates, the two moving blocks 1036 move towards each other at both ends of the bidirectional lead screw 1037 respectively. When the moving blocks 1036 move towards each other, they drive the two extension plates 1031 to move inside the adjustment slots 1032 respectively. When the extension plates 1031 move, the ends drive the support slide rods 1034 to support and slide inside the support slide slots 1033, so as to extend and open the extension plates 1031 to the sides of the lifting plate 103, and rotate the fixing bolt two 1035 to fix the extension plates 1031, facilitating the extension of the width of the lifting plate 103, so that when the installed equipment is placed on the surface of the lifting plate 103, it contacts and is extended and supported by the extension plates 1031, facilitating the extended support placement, increasing the contact area and making the lifting placement more stable, thereby improving the stability of the mobile lifting machine body 100 when lifting and installing a wider equipment;

[0036] Finally, when the extension plates 1031 are extended and opened to lift the equipment to a certain height and stay at the lifted height for a period of time for installation, the moving plate 1011 is limited to slide inside the limit moving slot 1013 by the limit block 1014 until the moving plate 1011 is slid open, and the fixing bolt one 1015 is rotated to fixedly install the limit block 1014 and the moving plate 1011, facilitating the fixed installation and support. After opening, the support leg 1012 is rotated to make the bottom end of the support leg 1012 contact the ground to support the moving plate 1011. The inner threaded rod 1017 is opened again and placed vertically, and the outer threaded rod 1016 is rotated inside the inner threaded rod 1017 to adjust to the support height until the card slot 1019 is moved and engaged inside the card head 1018, and the fixing bolt two 1035 is rotated to reinforce, so as to strengthen the support for the extension plates 1031 when the extension plates 1031 are opened to lift the equipment to a certain height for installation and stay. When the extension plates 1031 are stressed by gravity, they are not easy to shake, thereby improving the stability of the extension and opening support of the extension plates 1031 when the mobile lifting machine body 100 is lifted to a certain height for installation operation, and making the installation operation more stable.
