Two is because this structure is the traction ratio of 1:1, so the mode of cord strength when identical safety factor also than 2:1 that it requires is twice, and lifting platform end can only use 4 wire rope in the traction ratio of 1:1, this just increases wirerope diameter.Under safety standard requirements, corresponding guide wheel for steel wire diameter can be very large, and namely the weight of directive wheel strengthens, and the load of the machine room platform of top layer strengthens.
Three be overhaul or more change steel rope time the danger of 1:1 and difficulty be all greater than the hoisting way of 2:1.
Four is that 2:1 traction-type promotes and can adopt many wire rope (8-12 root) and the traction-type of 1:1 can only use 4 wire rope, and the safety of 4 groove wire rope is relatively low.
But use the hoisting way of 2:1 traction ratio also to have its self inevitable shortcoming.Because employ movable pulley on lifting platform, so may occur that when there is unbalance loading the front and back of lifting platform are out-of-level.And in the distribution of weight of automobile before and after there is unbalance loading and certainly exist because general front part of saloon car is equipped with motor, thus the center of car probably first three/place.There is unbalance loading when unloaded and fully loaded situation is inevitable to headstock direction, although lifting parts has 4 guide rails, front and back still have the discrepancy in elevation.Make up this discrepancy in elevation to need to compensate by increasing mechanical part.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanical interlocking mode and carries out pressure locking to garage lifter, lifter is moved in the turnover carrying out vehicle that level position can be safer, reduce the load of top, garage power hoisting device, increase the safety of lifter at flat bed.
A kind of vertical lifting multi-storied garage lifter flat bed locking method, described multi-storied garage lifter adopts traction ratio 2:1 hoisting way, the outer ledge of this lifter is provided with fastening screw, fastening screw controls to carry out pushing, shrinking by pusher, pin hole is provided with in the lifting hoistway corresponding with fastening screw position at level position, when lifter is in level position, controlling pusher work by the controller in garage makes fastening screw insert in pin hole, lifter and hoistway are connected as one, locks lifter by force at level position.
In technique scheme, described lifter outer ledge is provided with four fastening screws, and each side of described lifter arranges a fastening screw.
In technique scheme, preferential, described fastening screw is symmetrical arranged.
In technique scheme, described pusher is hydraulic cylinder.
In technique scheme, the Power output of described hydraulic cylinder connects four fastening screws simultaneously, controls four fastening screws and pushes simultaneously, shrinks.
In technique scheme, preferential, described pusher is screw rod or screw mandrel.
In technique scheme, described screw rod or screw mandrel are divided into two groups, each group employing power source, and one group connects two relative fastening screws, by rotating crosswise pushing or shrinking fastening screw.
In the utility model, adopt the mode of mechanical interlocking be occupy lifter carried out electric flat bed after locking again, electric flat bed is all adopted in existing flat bed mode, namely signal is sent by the induction of sensor, traction machine work is controlled by garage controller, the stretching wirerope of continuous adjustment lifter, thus reach the effect of flat bed, but in this case, when vehicle moves away or comes in time, the gravity that light weight brings can affect the level position of lifter, and now repeat flat bed operation again, if adopt mechanical locking mode after first time, level position terminated, by force the lifting hoistway in lifter and garage is fixed together, even if vehicle moves the gravity that brings or elastic force all can not make the position of lifter be moved, improve security performance greatly.
The retaining mechanism that the utility model adopts is bayonet fashion, the work of latch is controlled by power source, it can be generally hydraulic cylinder, simultaneously the benefit of hydraulic cylinder can control contraction and the propelling movement of four fastening screws by outputting power, and the failure rate is low of hydraulic cylinder, but the volume of hydraulic cylinder is comparatively large, and operation acts is comparatively slow, is arranged on that lifter to occupy space larger, can also be that motor provides power, the power that motor exports has leading screw or screw rod by laterally selecting to push or shrink fastening screw, the benefit of motor output power is exactly suitable fast of execution speed, compact structure, easy for installation, but what motor exported employing is select in the same way to export, therefore motor can only export the power in a direction, if work must export by two motor in synchrony while therefore will meeting four fastening screws, therefore in this case higher requirement is proposed to the control accuracy of motor, and the out of order frequency of motor is greater than hydraulic cylinder.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: by using method described in the utility model, adopt mechanical type flat bed, lifter can be locked by force, ensure high accuracy flat bed, eliminate the front and back discrepancy in elevation of lifting platform, reduce in the unloaded rope capacity change (change in length also comprises the elastic deformation of the spring in fag end combination) caused with lifting platform weight difference when loading simultaneously; Add the safety of garage in vehicle moving process.
