Machine security safety mechanism comprises: tooth bar, ratchet 93, pawl axis 122, axle, lid, sleeve and screw etc.
Travel mechanism comprises: the base of column 21 lower ends, roller, steering wheel 130, steering wheel support 125, depression bar 70, handgrip rudder 73, pull bar (87,88), needle roller, mobile parallels 79, screw etc.
The portable lifting machine of the utility model is according to automotive wheels bridge number and weight thereof, selects for use 4,6 or 8 mobile columns to layout lifting or decline automobile, and total system steadily rises or decline automotive safety by system controlled by computer.
Electromagnetic braking motor 63 is installed on every root post, moving through retarder slows down, for example adopt volume little, lightweight cycloidal-pin wheel retarder 59, again through the driver element gear of gear case 28 the insides for example, axle 44, bearing 47 grades drive the gear of ball screw 20 upper ends, be installed in ball screw 20 in the column 21 along with rotation, drive raising legs 102 liftings by the ball nut 94 that is fixed on fastener on the raising legs 102, and raising legs 102 is by track adjusting wheel 139,148 along the guide rail 140 that is connected with fastener on column 21 side plates, 142 rise or descend.With reference to accompanying drawing 9 to accompanying drawing 11, the guide wheel shaft 136 that two ends are fixed on raising legs 102 biside plates is provided with the gap that adjust the clearance element regulation guide rail is paid, for example guide rail is paid by quench edge steel V-type rail 140 and V-type track adjusting wheel 139 and flush type guide rail 142 and garden column type track adjusting wheel 148 and is constituted, make raising legs 102 move accurate and flexible, it is long that guide rail is paid the life-span, and maintain and replace is easy.The adjust the clearance element for example adopts eccentric bushing 145, and adjusting work is simple and easy to do.Raising legs 102 is by bearing 12, lining 14, gland 16 fixedly on the ball nut 94.Column 21 can or be cast as with the steel plate welding processing, and cost is low, good rigidity.Fastener for example can be selected screw (4,6,9,17,32,38,51), pin (3,19,55) for use.
The lifting crotch 10 that directly supports motor tire by intermediate member for example flanged shaft 8 be connected with raising legs 102, lifting crotch 10 can self-alignment be swung, make its raising legs 102 and column 21 force-bearing situations in the lift car process constant, increase the stability of complete machine.
The travel mechanism of every root post 21 lower ends is made of base, steering wheel 130 and the steering wheel crane 123 of two rollers, column 21 lower ends.Base and column 21 can also can link into an integrated entity with screw with welding.The steering wheel crane can drive the expanding-contracting action up and down that steering wheel support 125 is finished steering wheel 130 by manual handle 68 rotation depression bars 70, makes conveniently moving, changes flexibly.Move down when handle 68 clickwises push steering wheel support 125, steering wheel puts down.The governing screw of two parallels 79 of pine, the mobile parallels 79 of two kinks on the base spike of column leaves two rollers on the spike, and roller lands, and just can drag handgrip rudder 73 this moment, and column 21 can move.This shows that portable lifting machine is very convenient for the vehicle maintenance and repair maintenance,, power supply is arranged, this lifting machine is layouted supported automobile, just can keep in repair, maintain as long as a harder flat ground is arranged.Because inner structure is in closed state, open-air with keep internal junction clean in the same old way, part is not easy to get rusty and damage.
The utility model specially is provided with multiple electrical equipment and machine security insurance.The electrical equipment safety device is to be provided with overload protection, phase sequence and position limitation protection in electrical apparatus control system; In electromagnetic braking motor 63 ends position transduser is installed, guarantees raising legs 102 secure synchronization liftings on each column 21 by microprocessor control system; Also be provided with electromagnetic braking motor 63 on every root post, can prevent that trackslipping certainly of ball screw nut by gravity is moving.
Machine security safety mechanism for example can adopt tooth bar pawl type safety mechanism, be installed in the back side of column 21, with reference to accompanying drawing 12 and accompanying drawing 13, tooth bar adopts welding or is fastened on the column 21 by screw, ratchet 93 is by pawl axis 122, gland 121 is fixed on the raising legs 102, wherein one of ratchet 93 pawl is by bearing pin 89 and pull bar (87,88), electromagnet 85 is connected, by electrical equipment control, only electromagnet 85 just can be switched on when raising legs 102 motor-driven declines, when automobile is given rise to the needs height or be had a power failure suddenly, ratchet 93 just is locked on the tooth bar to fast and reliable automatically, and raising legs 102 just can not move down, the action good teamwork.Ratchet 93 adopts running-fit with pawl axis 122.Except with the tooth bar pawl type catch gear, can also adopt inclined wedge type locking to dream about or the bolt-type catch gear is locked.
The utility model also adopts the manual type lifting mechanism, for example adopt worm and worm gear, driving ball nut 94 wire winding rods 20 with hand worm screw 106 worm gears 11 rotates, the end face of ball nut 94 is connected with worm gear 11 with screw, worm shaft 106 two ends are installed on raising legs 102 biside plates, and worm shaft 106 1 ends can be adorned wind with hand moving.When take place having a power failure or electric appliance circuits when breaking down, just can realize raising legs 102 risings or decline with hand moving worm shaft 106, and finishing the self-locking of reverse drive.If do not need the manual type lifting mechanism, structure just can be simplified, and measure is exactly whole worm and wormwheel lifting mechanism cancellation, and raising legs 102 is fixing by sleeve, gland and ball nut 94.
The utility model also has the annex removable support, after automobile is lifted by the lifting machine, support with several removable supports, the lifting machine is removed, but the other automobile of lifting again, maintenance factory can reduce the platform number of buying the lifting machine like this, services a car easily, also can be used for dismantling spring, suspension, the propons back axle of automobile, driving engine etc.
The portable lifting machine of the utility model also can repack fixed type lifting machine into, as long as the portable mechanism of column 21 lower ends is cancelled, changes into the fixed type base, is fixed on the crash-resistant ground or is placed on the crash-resistant ground just passable with anchor bolt.
The utility model compared with prior art has obvious advantage and effect:
This movable lifting machine can be used for the lifting vehicle, is specially adapted to the maintenance of urban transportation car, special vehicle and the mining bogie below 35 tons, and dynamo-electric combination is rational in infrastructure, easy and simple to handle, safe and reliable, flexibly mobile, improved workman's working condition, cost is moderate, and the life-span is long.
