Specific embodiments

[0026] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0027] Embodiment 1:

[0028] As shown in the figure, a lifting platform for mechanical maintenance includes a base 1. The top outer wall of the base 1 is drivingly engaged with a lifting platform 3 for installing and fixing mechanical equipment through a lifting mechanism 2. The lifting mechanism 2 includes an extender one 5 and an extender two 11. The bottom end of the extender one 5 is fixed to the outer wall of the base 1, and the telescopic end of the extender one 5 is rotatably connected to the bottom outer wall of the lifting platform 3 through a hinge shaft 6. The bottom end of the extender two 11 is rotatably connected to the outer wall of the base 1, and the telescopic end of the extender two 11 is fixed with a connecting frame 10 through a bolt. The inner wall of the connecting frame 10 is rotatably connected with a limit shaft 7, and the bottom of the lifting platform 3 is fixed with a fixed frame 9 through a bolt. The fixed frame 9 is movably engaged with the outer wall of the limit shaft 7 through a strip groove 8 opened on its inner wall. Figures 1-5 In this embodiment, the specific types of the extender one 5 and the extender two 11 are not limited, and they can be pneumatic, electric, or hydraulic telescopic rods, or other linear displacement structures such as "lead screw slider". Preferably, both the extender one 5 and the extender two 11 are electric telescopic rods.

[0029]

[0030] ​When the first telescopic device 5 and the second telescopic device 11 expand and contract synchronously, the lifting platform 3 can be lifted. When the length of the first telescopic device 5 remains unchanged and the second telescopic device 11 expands and contracts, one end of the lifting platform 3 can be tilted by the connection between the limit shaft 7 and the strip-shaped groove 8, so as to realize the angle adjustment of the mechanical equipment.

[0031] In this device, by setting the first telescopic device 5 and the second telescopic device 11, on the one hand, the lifting function can be satisfied, and on the other hand, the flipping function of the lifting platform 3 can be realized by controlling the non-synchronization of the first telescopic device 5 and the second telescopic device 11, solving the limitation problem. Moreover, the realization of the flipping function and the driving source of the lifting function are the same, and only different control methods are adopted, thus simplifying the setting of the hardware equipment.

[0032] In this embodiment, a plurality of sliding grooves 12 are formed in the inner wall of the lifting platform 3. A slider 13 is slidably connected to the inner wall of the sliding groove 12, and a threaded hole 14 is formed in the inner wall of the slider 13.

[0033] The length directions of the plurality of sliding grooves 12 are not parallel.

[0034] During installation, the equipment can be placed on the lifting platform 3, and then the plurality of sliders 13 are slid so that the threaded holes 14 are aligned with the installation points of the equipment, and then the equipment can be fixed to the threaded holes 14 with bolts.

[0035] In this device, by setting the sliding grooves 12, the sliders 13 and the threaded holes 14, on the one hand, it can reliably fix the mechanical equipment, and at the same time, it can also use the sliding of the plurality of sliders 13 to fix the mechanical equipment with different mounting hole distances. After fixing, the position can be automatically locked by using the characteristic that the length directions of the plurality of sliding grooves 12 are not parallel, increasing the convenience of use.

[0036] In this embodiment, reinforcement components 4 are arranged at the four corners of the top of the lifting platform 3.

[0037] The reinforcement component 4 includes a hook 15, a telescopic member 16 and a universal connecting member 17. The hook 15 is fixed to one end of the telescopic member 16, and the other end of the telescopic member 16 is connected to the lifting platform 3 through the universal connecting member 17.

[0038] Since when the equipment deflects, if the height of the equipment is relatively large, using the form of bottom fixation will cause a relatively large bending moment on the top of the equipment, and there will be a risk of deformation and damage. When this device is used, the hook 15 can be hooked to the lifting lug of the equipment or other hookable parts, and then the telescopic member 16 can be adjusted to apply a pulling force.

[0039] In this device, by setting up the reinforcement assembly 4 composed of the hook 15, the telescopic member 16, and the universal connecting member 17, for equipment with a relatively large height, a combined form of bottom fixation plus top or side hook connection fixation can be adopted, thereby effectively preventing the bending deformation caused by the tilting of the equipment and increasing the reliability of use.

[0040] In this embodiment: When the first telescopic device 5 and the second telescopic device 11 expand and contract synchronously, the lifting platform 3 can be lifted and lowered. When the length of the first telescopic device 5 remains unchanged and the second telescopic device 11 expands and contracts, at this time, through the connection effect of the limit shaft 7 and the strip-shaped groove 8, one end of the lifting platform 3 can be tilted up, thereby realizing the angle adjustment of the mechanical equipment. When fixing, the equipment can be placed on the lifting platform 3, and then slide a plurality of sliders 13. After aligning the threaded holes 14 with the installation points of the equipment, use bolts to fix the equipment to the threaded holes 14, and then hook the hook 15 to the lifting lug of the equipment or other hookable parts, and then adjust the telescopic member 16 to make the telescopic member 16 straighten.

[0041] Embodiment 2:

[0042] A lifting platform for mechanical maintenance. In this embodiment, the following improvements are made on the basis of Embodiment 1, as Figures 1-5 shown, the telescopic member 16 includes a first screw rod 18, a sleeve 19, and a second screw rod 20. The first screw rod 18 is welded to the end of the hook 15, and the sleeve 19 is respectively connected to the first screw rod 18 and the second screw rod 20 through threads with opposite helix directions.

[0043] On the outer walls of the first screw rod 18 and the second screw rod 20, a locknut 23 is respectively connected through threads.

[0044] In this embodiment, the universal connecting member 17 includes a sphere 22 and a ball ring 21. The sphere 22 is fixed to the top outer wall of the lifting platform 3, and the ball ring 21 is fixed to the end of the second screw rod 20, and the ball ring 21 is wrapped and movably connected to the outer wall of the sphere 22.

[0045] In this embodiment: When the sleeve 19 is turned, the first screw rod 18 and the second screw rod 20 can be made to approach or move away from each other through the threaded connection effect. After the adjustment is completed, the locknut 23 can be turned so that the locknut 23 is closely attached to both sides of the sleeve 19, thereby forming an axial extrusion force, increasing the static friction force of the thread pair between the sleeve 19 and the first screw rod 18 and the second screw rod 20, and preventing loosening.
