[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 and 2 As shown, this embodiment discloses a platform support device for construction, including a support platform 1, a roller 2 is arranged at the bottom of the support platform 1, a platform 3 is arranged above the support platform 1, a scissor frame 4 is arranged between the platform 3 and the support platform 1, and four pairs of legs of the scissor frame 4 are rotatably connected to the foot seat,

[0018] The bases of a pair of legs at the upper part of the scissor frame 4 are fixed on the platform 3, and the bases of another pair of legs are slidably connected to the platform 3. The bases of a pair of legs at the lower part of the scissor frame 4 are fixed on the support platform 1, and the bases of another pair of legs are fixed on the slider 6.

[0019] A slide groove 5 is provided at the top of the support platform 1, and a slider 6 is slidably engaged in the slide groove 5. A first telescopic driving member 7 is also provided in the slide groove 5, and the telescopic end of the first telescopic driving member 7 is connected to the slider 6. A limiting groove 8 is provided at the bottom of the slide groove 5 at a position corresponding to the slider 6, and a movable plate 9 that can move up and down is provided in the limiting groove 8. A plurality of first inverted teeth 10 are provided at the top of the movable plate 9 along the movement direction of the slider 6, and a second inverted tooth 11 that cooperates with the first inverted teeth 10 is provided at the bottom of the slider 6. A plurality of first springs 12 are provided at the bottom of the movable plate 9, and the upper end of the first spring 12 abuts against the movable plate 9, and the lower end abuts against the bottom of the limiting groove 8. A second telescopic driving member 13 is provided above the movable plate 9 at its edge position, and the second telescopic driving member 13 is fixed on the limiting groove 8, and the telescopic end of the second telescopic driving member 13 abuts against the movable plate 9.

[0020] The working principle of the utility model is: when the device is in use, when the height of the platform 3 needs to be adjusted, the installed first telescopic driving member 7 drives the slider 6 connected thereto to move, the slider 6 slides to drive the scissor frame 4 connected thereto to move, and the scissor frame 4 drives the height of the platform 3 to be adjusted for use in construction.

[0021] When the first telescopic drive member 7 drives the slider 6 connected thereto to slide, the slider 6 drives the second inverted tooth 11 connected thereto to move, and the movement of the second inverted tooth 11 will compress the first inverted tooth 10 that matches it. During this process, the first spring 12 will be compressed. When the first inverted tooth 10 is disengaged from the second inverted tooth 11, the first inverted tooth 10 is reset under the action of the first spring 12, and then the first inverted tooth 10 is engaged with the second inverted tooth 11, so as to prevent the slider 6 from sliding in the opposite direction due to excessive pressure on the platform 3, thereby improving the installation performance of the device. When it is necessary to release the limit on the slider 6, the second telescopic drive member 13 moves downward to push the first inverted tooth 10 away from the second inverted tooth 11, so that the first inverted tooth 10 is disengaged from the second inverted tooth 11, and the limit on the slider 6 is released. Thereafter, the first telescopic drive member 7 drives the platform 3 to move downward.

[0022] In this embodiment, a buffer leg 14 is provided at the bottom of the platform 3, and the buffer leg 14 includes a telescopic rod 1401, the upper end of the telescopic rod 1401 is fixed to the platform 3, and the lower end is fixed to the buffer block 1402. A second spring 1403 is sleeved on the telescopic rod 1401, and one end of the second spring 1403 is against the platform 3, and the other end is against the buffer block 1402. When the first telescopic driving member 7 drives the platform 3 to move downward, the installed second spring 1403 will be compressed to generate elastic force, and the elastic force generated can play a buffering role on the platform 3, so that the platform 3 has a buffering deceleration process before falling to the lowest point, which plays a good buffering and protective role for the construction personnel on the platform 3.

[0023] In this embodiment, a guardrail 15 is arranged around the platform 3 .

[0024] In this embodiment, the first telescopic driving member 7 is an oil cylinder, and the second telescopic driving member 13 is an electric cylinder.

[0025] In this embodiment, a small winch 16 is provided on the platform 3 to facilitate workers to lift some goods.

[0026] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
