[0035] like Figure 1 and Figure 2 As shown, a fire safety assessment lifting platform disclosed in the second embodiment of the present utility model has a structure that is basically the same as that in the first embodiment, except that a lifting and fixing assembly 3 is provided at the inner bottom end of the movable frame 1, and the lifting and fixing assembly 3 includes a hydraulic cylinder 1 301, the hydraulic cylinder 1 301 is provided on the left and right sides of the inner top wall of the movable frame 1, and a support plate 302 is provided at the bottom end of the hydraulic cylinder 1 301, a convex block 303 is provided at the middle of the bottom end of the support plate 302, and anti-slip plates 304 are provided at both left and right ends of the support plate 302;

[0036] The equipment is moved and adjusted by the roller 11 at the bottom of the movable frame 1, and then after the position is determined, it is pressed downward by the hydraulic cylinder 301 to allow the protrusion 303 and the anti-skid plate 304 at the bottom of the support plate 302 to contact the ground. The rough contact improves the stability of placement, and the grounding support of the anti-skid plate 304 and the support plate 302 allows the roller 11 to leave the ground and prevent it from continuing to roll.

[0037] Embodiment three:

[0038] like Figure 3As shown, a fire safety assessment lifting platform disclosed in the third embodiment of the present invention has a structure that is basically the same as that in the second embodiment, except that an adjusting support assembly 4 is connected to the top of the support box 2, and the adjusting support assembly 4 includes a second hydraulic cylinder 401, the second hydraulic cylinder 401 is arranged at the inner middle part of the support box 2, and the left and right sides of the second hydraulic cylinder 401 are connected to a moving slide 402, and a rotating frame 403 is arranged at both the front and rear ends of the moving slide 402, and a driven support assembly 5 is arranged at the top of the rotating frame 403, and the driven support assembly 5 includes a driven slide 501, the driven slide 501 is arranged at the top of the rotating frame 403, and a sliding rod 502 runs through the inner side of the driven slide 501;

[0039] The extension and retraction of the hydraulic cylinder 2 401 can drive the movable slide 402 to move left and right, and then the rotating frames 403 on both sides of the movable slide 402 will rotate accordingly, thereby adjusting the position of the driven slide 501 to slide synchronously on the outside of the sliding rod 502. The height of the storage top plate 6 is controlled by the extension and retraction of the hydraulic cylinder 2 401, and the supports on both sides have a certain stability.

[0040] Embodiment 4:

[0041] like Figure 1 and Figure 4 As shown, a fire safety assessment lifting platform disclosed in the third embodiment of the present invention has a structure that is basically the same as that in the third embodiment, except that a storage top plate 6 is provided at the top of the driven slide plate 501, and a storage escalator assembly 7 is provided inside the storage top plate 6, the storage escalator assembly 7 includes an escalator body 701, and the escalator body 701 is connected to the inside of the storage top plate 6, and movable slide bars 702 are provided on the left sides of the front and rear ends of the escalator body 701, a rough panel 9 is provided in the middle of the top wall of the storage top plate 6, and guardrails 8 are provided around the top of the storage top plate 6, an adjustment fixing assembly 10 is connected to the right side of the movable frame 1, and the adjustment fixing assembly 10 includes a fixed block 1001, the fixed block 1001 is connected to the right side of the movable frame 1, and a telescopic adjustment rod 1002 is connected to the right side of the fixed block 1001, and a rotating installation inclined block 1003 is connected to the right side of the telescopic adjustment rod 1002;

[0042] The front and rear walls of the storage top plate 6 are through-through and hollow inside, which is convenient for the left and right movement adjustment of the escalator body 701. The grooves on the front and rear walls of the storage top plate 6 limit the moving position of the movable slide bar 702. The right side of the bottom wall of the storage top plate 6 is open, which is convenient for the escalator body 701 to be rotated and adjusted when it moves to the far right. After the escalator body 701 is rotated, the telescopic adjustment rod 1002 is used to adjust the telescopic position, so that the rotating installation bevel block 1003 is rotated and adjusted to a certain angle and fits with the rotated escalator body 701, and then fixed in the matching screw holes with screws, thereby improving the storage and use efficiency.

[0043] The specific scheme is as follows: first, the equipment is moved and adjusted by the roller 11 at the bottom of the movable frame 1. Then, after the position is determined, the hydraulic cylinder 1 301 is pressed downward to allow the protrusion 303 at the bottom of the support plate 302 and the anti-slip plate 304 to contact the ground. The rough contact improves the stability of the placement. The anti-slip plate 304 and the ground support of the support plate 302 allow the roller 11 to leave the ground and prevent it from continuing to roll. Then, the extension and retraction of the hydraulic cylinder 2 401 can drive the movable slide 402 to move left and right, and then the rotating frames 403 on both sides of the movable slide 402 will rotate accordingly, thereby adjusting the position of the driven slide 501 to slide synchronously on the outside of the sliding rod 502, and the height of the storage top plate 6 is controlled by the extension and retraction of the hydraulic cylinder 2 401. The side support has a certain stability. At this time, the front and rear walls of the storage top plate 6 are penetrated and the interior is hollow, which is convenient for the left and right movement adjustment of the escalator body 701. The grooves on the front and rear walls of the storage top plate 6 limit the moving position of the movable slide bar 702. The right side of the bottom wall of the storage top plate 6 is open, which is convenient for the escalator body 701 to be rotated and adjusted when it moves to the far right. After the escalator body 701 is rotated, the telescopic position is adjusted by the telescopic adjustment rod 1002, and the rotating installation bevel block 1003 is rotated and adjusted to a certain angle and then fits with the rotated escalator body 701, and then fixed in the matching screw holes with screws, which is convenient for the assessors to climb and use. The rough panel 9 on the top is convenient for standing and anti-slip, and the guardrail 8 has a certain protective performance.
