[0022] Example: like Figures 1 to 4 As shown, according to an overall technical concept of the present invention, a multi-degree-of-freedom adjustable scissor-type lifting platform is provided, comprising: Fixed seat 1; A movable seat 2, which is arranged above the fixed seat 1; The scissor lift assembly 3 is composed of a first scissor lift mechanism 31 and a second scissor lift mechanism 32. The first scissor lift mechanism 31 and the second scissor lift mechanism 32 are arranged between the fixed seat 1 and the movable seat 2 along the front-back direction. The first scissor lift mechanism 31 and the second scissor lift mechanism 32 cooperate with each other and are used to control the lifting height and tilt angle of the movable seat 2. The feeding drive mechanism 4 is connected between the scissor-type lifting assembly 3 and the movable seat 2, and the feeding drive mechanism 4 is used to drive the movable seat 2 to reciprocate along its own length direction.

[0023] like Figures 1 to 4 As shown, in an exemplary embodiment of the present invention, the fixed seat 1 and the movable seat 2 are both constructed as a frame-shaped structure, and two groups of first roller grooves 11 are arranged oppositely on the left and right sides of the fixed seat 1, and two groups of second roller grooves 21 are arranged oppositely on the left and right sides of the movable seat 2.

[0024] like Figures 1 to 4 As shown, in an exemplary embodiment of the present invention, the first scissor-type lifting mechanism 31 is cross-hinged by the first long arm group 311 and the first short arm group 312, and the second scissor-type lifting mechanism 32 is cross-hinged by the second long arm group 321 and the second short arm group 322; the bottom ends of the first long arm group 311 and the second long arm group 321 are hinged to the two groups of first roller grooves 11, and the top ends of the first long arm group 311 and the second long arm group 321 are both provided with first rollers, and the two groups of first rollers are rollingly connected in the two groups of second roller grooves 21 in a one-to-one manner; the bottom ends of the first short arm group 312 and the second short arm group 322 are both provided with second rollers, and the two groups of second rollers are rollingly connected in the two groups of first roller grooves 11 in a one-to-one manner.

[0025] like Figures 1 to 4As shown, in an exemplary embodiment of the present invention, the first scissor-type lifting mechanism 31 also includes a first telescopic cylinder 313, and the second scissor-type lifting mechanism 32 also includes a second telescopic cylinder 323; the fixed end of the first telescopic cylinder 313 is hinged to the connecting rod at the bottom end of the first long arm group 311, and the movable end of the first telescopic cylinder 313 is hinged to the connecting rod at the top end of the first short arm group 312; the fixed end of the second telescopic cylinder 323 is hinged to the connecting rod at the bottom end of the second long arm group 321, and the movable end of the second telescopic cylinder 323 is hinged to the connecting rod at the top end of the second short arm group 322.

[0026] like Figures 1 to 4 As shown, in an exemplary embodiment of the present invention, the feeding drive mechanism 4 adopts a third telescopic cylinder 41, the fixed end of the third telescopic cylinder 41 is hinged to the connecting rod at the top of the first short arm group 312 or the second short arm group 322, and the movable end of the third telescopic cylinder 41 is hinged to the connecting rod between the two groups of second roller grooves 21.

[0027] like Figures 1 to 4 As shown, in an exemplary embodiment of the present invention, it also includes a circumferential rotation mechanism (not shown), which adopts a rotating table. The rotating table is arranged on the bottom side of the fixed seat 1 and rotates circumferentially due to supporting the fixed seat 1.

[0028] It should be noted that the scissor-type lifting platform involved in the present scheme can realize circumferential rotation through a circumferential rotation mechanism (adjusting the placement posture of the photovoltaic components, placing them horizontally or vertically, and avoiding interference during transportation); it can also realize the lifting and lowering of the movable seat 2 and the control of the front and rear tilt angles through the scissor-type lifting assembly 3 (this structure can control the lifting height and installation angle of the photovoltaic components, which is convenient for on-site assembly); in addition, the function of delivering the photovoltaic components to the photovoltaic bracket can be realized through the feeding drive mechanism 4, thereby reducing the assembly burden (this structure can control the movable seat 2 to move forward and backward along its own length direction, so as to facilitate the delivery of the photovoltaic components to the photovoltaic bracket for assembly).

[0029] Specifically, a component pre-installation area 100 and a bracket area 200 are set at the photovoltaic installation site, and two relatively spaced support members 110 are set in the component pre-installation area 100, and the assembled photovoltaic components are hoisted to the support members 110 and suspended. The scissor-type lifting platform is moved to the bottom of the photovoltaic component by a crawler vehicle equipped with a scissor-type lifting platform, and then the photovoltaic component is lifted up and separated from the support member 110 by controlling the scissor-type lifting platform (before the photovoltaic component is separated from the support member 100, it needs to be reinforced to prevent it from being separated from the movable seat 2), and then the photovoltaic component is moved out of the range of the support member 100 by the crawler vehicle; then, the scissor-type lifting platform is lowered (to prevent the photovoltaic component from shaking during transportation) and the photovoltaic component is sent to the bracket area 200. After arriving at the bracket area 200, the photovoltaic component is first lifted up by the scissor-type lifting platform and adjusted to a suitable tilt angle, and then the movable seat 2 is sent out by the feeding drive mechanism 4, so that the photovoltaic component is sent to the photovoltaic bracket.

[0030] Therefore, the present invention has the following advantages: The present invention proposes a multi-degree-of-freedom adjustable scissor-type lifting platform, which can realize the lifting and lowering of a movable seat and the control of the front and rear tilt angles through a scissor-type lifting component. In addition, the extension and retraction of the movable seat can be realized through a feeding drive mechanism, which is convenient for feeding and installation. The scissor-type lifting platform is used in conjunction with a photovoltaic assembly trolley to realize the rapid transportation of photovoltaic components and is suitable for on-site installation of photovoltaic components.
