Detailed description of the invention

This utility model one specific embodiment is proposed as depicted in figs. 1 and 2, omnidirectional based on ball-screw regulation height Mobile lifting platform car, including hollow chassis 1, be located at the One On The Chassis hoistable platform 2, the both sides pair, one end on described chassis 1 Claiming to be provided with between drive 4 and two drives 4 to be provided with power transmission shaft 5, described power transmission shaft 5 is provided with travelling gear 5-1, described transmission Gear 5-1 connects the first driving means 6, and the other end on described chassis is symmetrically arranged on two with two universal wheels 7；Described chassis 1 with Being connected by lifting assembly 3 between hoistable platform 2, described lifting assembly 3 includes being symmetrically set between hoistable platform 2 and chassis 1 Both sides and setting up and down some groups lifting motion bar groups 3-1, be hinged and hinged between adjacent lifting motion bar group 3-1 Place is provided with lifting carriage 3-2, and described lifting motion bar 3-1 group includes the two motion bar 3-1-being hinged into crossbar architectures 1, the group number of lifting assembly 3 the most rationally can be arranged according to the length of concrete operations height combining movement bar, typically carries out work The height made is higher, and the group number of lifting assembly 3 can arrange more, and the height being typically operated is shorter, lifting assembly 3 Group number can arrange few, two motion bar 3-1-1 be all one end hinged fixing, the other end is hinged fixing by slide block 3-3, and Two motion bar 3-1-1 hinged ends are reversed, the top of i.e. one motion bar 3-1-1 be hinged fixing, bottom be by slide block 3-3 Hinged fixing, then the top of another hinged motion bar 3-1-1 is to be hinged fixing by hinged fixing, the other end of slide block 3-3, Described hoistable platform 2, lifting carriage 3-2, the both sides on chassis 1 are equipped with and can allow the chute 3-4 of slide block 3-3 linear slide, logical Cross slide block 3-3 to be hinged between two motion bar 3-1-1 of hoistable platform 2 both sides and be provided with slide rail 3-5, sheathed on described slide rail 3-5 There is ball-screw nut 3-6, in described first ball-screw nut 3-6, be arranged with the ball-screw 3-7 being connected with it, institute State that one end of ball-screw 3-7 is fixed in hoistable platform 2, the other end connects the second driving means 3-by reduction gearing 3-8 9, described hoistable platform 2 is provided with panel 2-1, described panel 2-1 controls respectively lifting assembly 3 lifts, drive 4 enters Direction switch 2-2, the advance and retreat switch 2-3 moved back.

Described first driving means the 6, second driving means 3-9 is disposed as servomotor, and servomotor can make control speed Degree, positional precision are the most accurate, it is also possible to voltage signal is converted into torque and rotating speed to drive control object, thus ensure to fill The position that the lifting put and horizontal omnidirectional move is accurately and speed easily manipulates, it is ensured that device is easy to operate and safety, simultaneously Be conducive to improving work efficiency.

When this utility model uses: first driving means the 6, second driving means 3-9 connects power supply, if lifting device is carried out During work high above the ground, starting direction switch 2-2, now the first driving means 3-8 rotates forward, thus just drives ball-screw 3-7 To rotation, and then slide rail 3-5 slides to the right in chute 3-4, is hinged on the motion bar 3-1-1 on chassis 1 to the right by slide block 3-3 Sliding, all motion bar 3-1-1 being hinged on this motion bar 3-1-1 are all to slide to the right, and are directly hingedly fixed in chassis 1 On motion bar 3-1-1 and be hinged on all motion bar 3-1-1 of this motion bar 3-1-1 and only rotate up action, slide rail 3-5 When sliding into the low order end of chute 3-4, the maximum height risen for device, as shown in Figure 1.

If during folding shrinking lowering or hoisting gear, starting direction switch 2-2, now the first driving means 3-8 reversely rotates, from And drive ball-screw 3-7 to reversely rotate, and then slide rail 3-5 slides in chute 3-4 to the left, is hinged on the end by slide block 3-3 The motion bar 3-1-1 of dish 1 slides to the left, and all motion bar 3-1-1 being hinged on this motion bar 3-1-1 are all to slide to the left, And be directly hingedly fixed in the One On The Chassis motion bar 3-1-1 and be only hinged on all motion bar 3-1-1 of this motion bar 3-1-1 It is rotated down action, when slide rail 3-5 slides into the high order end of chute 3-4, lowering or hoisting gear folding shrinking, as shown in Figure 3.

If lowering or hoisting gear horizontal linear moves, start the switch 2-3 that retreats, and the switch 2-3 that retreats can control the first driving The rotating forward and reversely rotating of device 6, thus drive mobile drive 4 to rotate forward or reversely rotate by power transmission shaft 5, Chassis 1 is then made to advance in the horizontal plane or retreat；Drive 4 combines universal wheel 7 can make chassis 1 can carry out in the horizontal plane entirely To movement, convenient and swift, time saving and energy saving.

Certainly, the most simply combine accompanying drawing this utility model preferred embodiment to be described in detail, not Limiting practical range of the present utility model with this, all equivalences made according to principle of the present utility model, structure and structure change, All should be covered by protection domain of the present utility model.
