Principle of work of the present invention: oil cylinder and power-transfer clutch all adopt hydraulic-driven.Power-transfer clutch adopts three-clove style taper sleeve type screw serrated form claw and lifting arm deciliter, by tapered sleeve piston transmitted load to oil cylinder piston or cylinder body.Reset and adopt spring force and guiding awl to finish.The built-in hydraulic control one-way valve in downforce chamber of each oil cylinder is guaranteed reliable in action, and under the state in the source of running out of steam, gig can automatically lock in situ very reliably.
When needs lifting work, according to programmable setting requirement, original dormant state can be set at up and down, and power-transfer clutch is locking state, operation PLC control capsule switch drive hydraulic efficiency pressure system, at first make down power-transfer clutch make separating action, and make the line pressure oil pocket begin lifting work according to the following feedback on reservation signal sequence of the pressure relay of power-transfer clutch acting chamber, piston rod promotes operation platform and covers a stepping stroke, this moment, the feedback on reservation signal sequence according to the external coding displacement sensor of cylinder body closed clutch operating, make the cylinder pedestal bearing load, the feedback on reservation signal sequence of the pressure relay of power-transfer clutch acting chamber is opened power-transfer clutch under the basis then, and make the piston rod of line pressure oil pocket return original position according to the feedback on reservation signal sequence of the last power-transfer clutch acting chamber pressure relay that is the upward pressure oil pocket, feedback on reservation signal sequence according to the external coding displacement sensor of cylinder body closes the built-in last power-transfer clutch of piston rod again, thereby makes the piston rod bearing load finish the work of a step cycle.According to this, go round and begin again and just can finish whole lifting work.Otherwise the then work that can do to descend.
Fig. 3 is a hydraulic schematic diagram of the present invention, wherein 20-hydraulic pump combination, 21-3-position 4-way automatically controlled (Y type meta function) change-over valve, 22-governor valve, 23-hydraulic control one-way valve, 24-pressure sensor, 25-PLC control box.Hydraulic efficiency pressure system adopts the mesohigh quantitative plunger pump to do propulsion source, and pressure and flow can be set up at any time according to specific requirement.Action control then adopts PLC, pressure sensor, coding site sensor and elements such as 3-position 4-way electric control reversing valve, manual governing valve to satisfy the action and the rate request of gig, in order to prevent that improper reasons such as hydraulic system fault or conduit under fluid pressure damage from causing pressure release, hydraulic control one-way valve then is built in the cylinder block, as the configuration of secure hardware.All the time guarantee the reliable self-locking of gig.
Hydraulic Pump propulsion source, control PLC case, pressure sensor, 3-position 4-way electric control reversing valve, manual governing valve and hydraulic oil outlet flow divider valve piece be all integrated to be designed to a trolley type combination mobile unit, and good looking appearance is installed easily, and is easy to operate.
In engineering construction, when needs promote operation platforms such as sliding formwork, creeping formwork, can adopt all-hydraulic step hoister of the present invention to promote operation platform, as shown in Figure 2, determine suspension centre quantity according to the size of operation platform at first earlier.Some guiding support posts 19 are installed on the pinnacled building operation facility.
General two gigs that are positioned at guiding support post both sides that adopt are fixed on the same lifting support 15 as one group, pass by two lifting arms 1 and promote support 15, the ball pivot nut 10 of its lower end and operation platform 16 hang suspension centre of boots 17 hinged compositions; Two gigs of a suspension centre are installed on the lifting support 15 that rises simultaneously or descend with it with attachment bolt, on lifting support 15 and operation platform 16, tumbler pusher dog 18 is set, promote support and steel platform in order to support, both all are sleeved on lifting on the guiding supporting construction column 19; On the guiding support post as required spacing have and support fenestra and 18 mating reactions of tumbler pusher dog.
Be that example is done application note with suspension centre of steel flat-bed below:
When the needs lifting, the primer fluid pressing system, the hydraulic hoisting machine that drives each suspension centre enters the pattern of climbing synchronously, make earlier and promote support 15 on request along the guiding support post 19 automatic steppings predetermined altitude that climbs, support 15 to be hoisted with tumbler pusher dog 18 reset enter support fenestra after, commutation action makes and promotes support 15 and descend, and will promote support 15 by tumbler pusher dog 18 and be fixed on the guiding support post 19 support fenestras on this height.
The switching controls mode is operated gig and is entered the lifting pattern then, the automatic on request stepping of whole construction platform 16 is risen to predetermined altitude, the back commutation that resets of the tumbler pusher dog for the treatment of operation platform 16 descends, and whole construction platform 16 is slowly fallen after rise be fixed on guiding support post 19 by tumbler pusher dog 18 to support on the fenestras.
And the like, the work of repetition can repeatedly promote operation platforms such as sliding formwork, creeping formwork.
Principle of work during decline is similar to lifting, earlier platform is improved a stroke, pins tumbler pusher dog 18, and commutation work gets final product then.
The hydraulic control system of the hydraulic hoisting machine between each suspension centre adopts different combinations according to sliding formwork, creeping formwork size.The sequence of operation that reaches synchronously of the hydraulic hoisting machine of each suspension centre then adopts the position transduser of configuration and pressure sensor signal to feed back, finish whole algorithm by the PLC interlocked control, in the time of can avoiding manual operation, because tired, slack and other reasons cause misoperation and produce serious damage sequence.
