Specific embodiment
The invention will be further described with the following Examples.
Multistage screw rod 3 for promotion of the invention combines the specific embodiment of lifting device with lift cylinder 11, such as
Shown in Fig. 1 and Fig. 2, including pressure-bearing platform 8, three movable platforms and the lower supporting frames being sequentially sleeved on guide rail from top to bottom
10.Guide rail is assembled by the affixed standard knot of multiple stackings, and each standard knot offers the working end for flexible bracket 9
The card slot of insertion.Pressure-bearing platform 8 and lower supporting frame 10 are provided with flexible bracket 9, and as a preferred option, lower supporting frame 10 is set
It sets there are two flexible bracket 9, two flexible brackets 9 respectively symmetrically are mounted on the bottom surface of lower supporting frame 10；Bearing platform setting
There are two flexible bracket 9, two flexible brackets 9 are symmetrically mounted at the top end face of pressure-bearing platform 8.Guide rail in the vertical direction between
Every the card slot for being provided with multiple working end insertions for flexible bracket 9.Specifically, the bracket 9 that stretches is horizontally disposed flexible liquid
The working end of cylinder pressure, telescopic hydraulic cylinder is connected with claw, and under caught state, claw is inserted into the card slot of guide rail (standard knot).
It should be noted that pressure-bearing platform 8 is the truss platform that those skilled in the art claim, predominantly work platform.
Be as improved, see Fig. 2, movable platform include lift cylinder 11, expansion bearing beam 7 and with expansion bearing beam
7 screw rod backbars 12 that are parallel and being positioned above two sides, lift cylinder 11 is fixedly mounted on expansion bearing beam 7, and is promoted
The telescopic rod of oil cylinder 11 and screw rod backbar 12 are affixed；The side of screw rod backbar 12 is inlaid with Synchronous lifting nut 5, screw rod branch
Bolster 12 is provided with the quick return nut 2 coaxial with Synchronous lifting nut 5, and lifting device is additionally provided with a lead screw and sequentially passes through
Synchronous lifting nut 5 and quick return nut 2, screw rod backbar 12 are equipped with quick return hydraulic motor 1, and quick return is hydraulic
Motor 1 and Synchronous lifting nut 5 are sequentially connected, and expansion bearing beam 7 is equipped with Synchronous lifting hydraulic motor 4, and Synchronous lifting is hydraulic
Motor 4 and Synchronous lifting nut 5 are sequentially connected；Expansion bearing beam 7 and lower supporting frame 10 positioned at the movable platform of bottom is solid
It connects, the expansion bearing beam 7 positioned at the lead screw and the workbench being positioned above of the movable platform of bottom is affixed, is located at most upper
The lead screw and pressure-bearing platform 8 of the movable platform of side are affixed.
The multistage screw rod 3 for promotion of the present embodiment combines the course of work of lifting device with lift cylinder 11, first
Under beginning state, the flexible bracket 9 of pressure-bearing platform 8 and the flexible bracket 9 of lower supporting frame 10 are inserted into guide rail, are in clamping shape
State, pressure-bearing platform 8 are in position to be hoisted, i.e. the distance between pressure-bearing platform 8 and lower supporting frame 10 is most short, at lift cylinder 11
In retracted state, if pressure-bearing platform 8 needs to be promoted, the flexible bracket 9 of pressure-bearing platform 8 is withdrawn out of guide rail, lower supporting frame 10
Flexible bracket 9 is in state in insertion guide rail；Lift cylinder 11 on the expansion bearing beam 7 of each movable platform stretches out, and drives
Quick return nut 2 moves upwards, and quick return nut 2 drives screw rod 3 to move upwards, at this point, Synchronous lifting hydraulic motor 4 is just
Turn that Synchronous lifting nut 5 is driven to rotate forward, formation lift cylinder 11 and Synchronous lifting nut 5 so simultaneously acts on 3 force of screw rod
Lifting force is formed, such lift cylinder 11 is then used as main lifting force, and Synchronous lifting nut 5 is then used as service hoisting power, synchronizes and mention
The case where rising nut 5 mainly prevents lift cylinder 11 from bursting, and screw rod 3 or pressure-bearing platform 8 drop suddenly, this ensure that
