DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] See also Figure 1-4 A mobile lifting platform includes a lifting platform 1, on which people can stand, objects can be placed, and support and installation space are provided for some components in the device. A scissor-type lifting unit 2 is movably connected to the bottom of the lifting platform 1, which can control the rise and fall of the lifting platform 1, and the entire device can also be moved by a push handle. This is a prior art and will not be described in detail here. Fixed splints 3 are respectively fixedly connected to the front and rear sides of the top of the lifting platform 1, and two strip through holes 4 are provided on each fixed splint 3 at intervals in the horizontal direction. Two movable splints 5 are movably arranged between the two fixed splints 3, and movable blocks 6 are respectively fixedly connected to the front and rear sides of each movable splint 5. Each movable block 6 movably passes through the corresponding strip through hole 4. Through the cooperation of the movable block 6 and the strip through hole 4, the movable splint 5 can be moved left and right. A spacing adjustment mechanism 7 connected to two moving blocks 6 on the same side is provided on the outside of the fixed clamping plate 3. The moving blocks 6 can move under the action of the spacing adjustment mechanism 7, thereby driving the two moving clamping plates 5 to move toward or in the opposite direction, so as to clamp objects of different sizes, prevent the objects from shaking during the lifting process, and thus increase the safety of the objects. A first handrail 8 with adjustable height is provided on the top of each fixed clamping plate 3, and a second handrail 11 with adjustable height is provided on the top of each moving clamping plate 5. Since both the first handrail 8 and the second handrail 11 can be adjusted in height, they can adapt to the heights of different construction workers.

[0021] Furthermore, sliders 12 are fixedly connected to the front and rear sides of the proximal lower end of the movable splint 5, and strip slide grooves 13 cooperating with the sliders 12 are respectively opened on the inner side of each fixed splint 3, and each strip slide groove 13 is parallel to the strip through hole 4, respectively. Through the cooperation of the strip slide grooves 13 and the sliders 12, a guiding effect is played for the movable splint 5, and the movable splint 5 is more stable when moving.

[0022] Furthermore, the spacing adjustment mechanism 7 includes two fixed blocks 701 fixedly connected to the outside of the fixed clamp plate 3 at intervals in the horizontal direction, a bidirectional threaded rod 702 is rotatably connected between the two fixed blocks 701, and a driving unit 703 linked to the bidirectional threaded rod 702 is arranged on the outside of the fixed clamp plate 3; the driving unit 703 includes an installation box, and a servo motor installed in the installation box, and the bidirectional threaded rod 702 is driven by the servo motor to rotate forward or reverse, which is a prior art and will not be described here. Screw sleeves 704 are respectively threadedly connected to the two threaded sections of the bidirectional threaded rod 702 with different rotation directions, and each moving block 6 is fixedly connected to the outer ring of the corresponding screw sleeve 704. The driving unit 703 drives the bidirectional threaded rod 702 to rotate forward or reverse, thereby driving the two screw sleeves 704 to move closer to or away from each other, and then the position of the moving clamp plate 5 can be adjusted to clamp the object.

[0023] Furthermore, the first handrail 8 is in an inverted U shape, and a plug plate 9 is fixedly connected to the lower end of the first handrail 8. A slot adapted to the plug plate 9 is provided on the fixed splint 3, and the plug plate 9 can move up and down in the slot. A plurality of adjustment holes 10 are provided at equal intervals in the vertical direction on the plug plate 9, and a limit assembly 14 adapted to the adjustment holes 10 is provided on the fixed splint 3; the structure of the second handrail 11 is the same as that of the first handrail 8. When the height of the handrail needs to be adjusted, the plug plate 9 is moved in the slot to adjust the height of the handrail. After the adjustment is completed, the position of the plug plate 9 is fixed by the cooperation of the limit assembly 14 and the adjustment hole 10, so as to adapt to construction workers of different heights.

[0024] Specifically, the limit assembly 14 includes a mounting plate 141, and two plugs 142 are fixedly connected at intervals along the vertical direction on one side of the mounting plate 141 close to the fixed clamping plate 3, and the plugs 142 can pass through the adjustment hole 10. A limit screw 143 is fixedly connected to the mounting plate 141 between the two plugs 142, and the limit screw 143 can pass through the adjustment hole 10. A limit nut 144 is threadedly connected to the outer end of the limit screw 143; a through hole corresponding to the plug 142 and the limit screw 143 is opened on the fixed clamping plate 3, and the diameter of each through hole is the same as the diameter of each adjustment hole 10, and the spacing between each through hole is the same as the spacing between each adjustment hole 10. When the plug plate 9 is moved to the height required by the construction worker, the center of the through hole and the adjustment hole 10 are coincident, and then the latch 142 and the limit screw 143 are passed through the through hole and the adjustment hole 10, and then the limit nut 144 is screwed on to limit and fix the handrail. The structure is simple, and only a small number of nuts need to be tightened to quickly fix the handrail, which is easy to use.

[0025] When in use, the device is moved to a designated position. If items need to be transported, the items can be placed on the lifting platform 1, and then the driving unit 703 drives the bidirectional threaded rod 702 to rotate, so that the two movable clamps 5 are close to each other to clamp the items, and then the items are lifted and transported to avoid damage caused by shaking during the transportation of the items.

[0026] If it is necessary to transport the construction workers, the construction workers raise or lower the height of the handrail according to their own height so that the center of the through hole coincides with the center of the adjustment hole 10, and then pass the latch 142 and the limit screw 143 through the through hole and the adjustment hole 10, and then tighten the limit nut 144 to limit and fix the handrail to ensure their own safety. Finally, the construction workers are safely delivered through the scissor-type lifting unit 2.

[0027] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the explanation of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
