Description
Technical field
The utility model relates to a kind of driving device of lifting vehicle.
Background technology
The jacking system of existing lifting vehicle is generally jack, perhaps the swing arm lifting device of the cylinder that uses in the car repair shop (or hydraulic pressure) driving.Wherein, the jack lift height is less, usually only is used for the lifting work of ease of Use such as changing of tire, and structure comparatively complexity be not suitable for lifting vehicle by a relatively large margin.And its transmission of swing arm lifting device is hydrostatic drive or cylinder transmission, complex structure, and volume is big, is unfavorable for maintenance.In addition, no matter jack or swing arm lifting device directly push up the act car chassis, easily damage is caused on the chassis.
Summary of the invention
The purpose of this utility model is to provide a kind of driving device of lifting vehicle, the vertical ball screw that is provided with of chain drive by a plurality of horizontal reaches the purpose of lifting vehicle, and simple in structure, cost is low, easy to maintenance, solve the problems referred to above that prior art exists.
Above-mentioned technical purpose of the present utility model mainly is the driving device of the lifting vehicle that solves by the following technical programs, it is characterized in that comprising the chain of a plurality of horizontal, the drive element of chain drive-belt, and the ball screw of the vertical setting that cooperates with chain gear, the chain that cooperates with drive element stacks for two groups.The vertical ball screw that is provided with of chain drive by a plurality of horizontal reaches the purpose of lifting vehicle, avoids changing by bevel gear in the prior art direction of vertical chain gear, and is simple in structure, easy to maintenance.
As further improving and replenishing to technique scheme, the utility model adopts following technical measures: described ball screw is four, connect successively by chain, form three and drive the limit, wherein, the chain that cooperates on the ball screw in the middle of being positioned at stacks for two groups, and in this three drivings cooresponding position, limit cover body is set respectively.Ball screw is four, rotates by every ball screw of chain drive, arrives the purpose of lifting vehicle.Drive a messenger chain that drives on the limit, two ball screws that chain on this driving limit drives on this driving limit rotate, ball screw rotates the other one group of chain work that stacks that then drives simultaneously, drives all the other screw mandrels successively and rotates simultaneously, reaches the purpose that each screw mandrel reaches synchronization action.When wherein a chain ruptured or is out of order, all the other chains can not rotate simultaneously, and each screw mandrel can reach the purpose of synchronization action equally.
Described ball screw is at least four, connects in twos by chain, forms four and drives limits, and the chain that cooperates on every ball screw stacks for two groups, and in the moving cooresponding position, limit of this 4 wheel driven cover body is set respectively.
Described drive element is arranged on and drives on the limit, drive element comprises motor, by motor-driven change speed gear box, driving axial on the change speed gear box extends down, axle drive shaft is provided with two gears that stack up and down, and the driving limit that is provided with drive element is provided with two chains, and the driving limit that is provided with drive element is provided with two chains, article two, two of chain in opposite directions the end respectively with axle drive shaft on two gear matched, two oppositely directed ends then are connected with the ball screw at these two ends, driving limit.The work of driven by motor change speed gear box, and then two chains that drive is connected on the change speed gear box rotate last each screw mandrel synchronization action that drives synchronously simultaneously.
Described drive element is two groups, is separately positioned on the two relative driving limits, and all the other chains that drive on limits are one.Drive element is two groups, then the power of motor on every group of drive division can reduce half, therefore motor volume also diminishes, when the direct chain that drives of a drive element is out of order (breaking) as chain, because the chain that is the actuating unit direct drive breaks, and cooperate more concentratedly between should chain and other chains at place, the chain that then breaks throws away and blocks other chains, and forces motor overload and quit work.
When if the driving limit is four, if a driving limit or two chains that drive on the limit of drive element are not set to be out of order, perhaps, if driving the limit is three, if a chain that drives on the limit of drive element is not set to be out of order, chain is not easy to throw away and blocks other chains, all the other chains still can work on, but, detection part can in time detect fault by being set, even and the decline carriage is to ground, shift out on-call maintenance behind the vehicle, avoid vehicle to be waited for maintainer arrive maintenance and the appearance of the phenomenon that wastes time aloft by the carriage holder.
The two side of the cover body at nearly ball screw place is provided with the holder part respectively, and the holder part is the pilled-in selvedge and the slack list of the nearly chain ends of support respectively.The holder part setting, prevent that chain is sagging, make chain all the time can with the gear correct engagement on the screw mandrel.
The two side of described cover body respectively spacing a plurality of sidewall gears are set, and the sidewall gear on two madial walls is cooresponding in twos respectively to be arranged on the same straight line of the same cross-sectional plane of cover body, and between the pilled-in selvedge of described chain and slack list a plurality of Tension gear is set also.Because it is longer to drive the limit, generally corresponding with the length that parks cars, width, by with the interlock of sidewall gear, make the smooth transmission of chain.After the chain long-term work, produce looseness, and the setting of Tension gear helps in time being adjusted in the suitable tightness of chain.
The inboard interlock of the pilled-in selvedge of described Tension gear and chain and slack list, and be suspended on the chain.Because chain is longer, and only pass through the support of holder part in the end, have certain sagging in the middle part, and after the long-term work, chain fluffs, and it is big that sag becomes, Tension gear is suspended on the chain, rather than be fixed on down on the joint pin by strut member, help all the time and the chain interlock, make transmission smooth.
The beneficial effect that the utlity model has: 1, the fit system of chain and ball screw and drive element makes transmission safe and reliable; 2, chain keeps flat stackedly, and the ball screw that direct drive is vertical avoids adopting parts such as bevel gear to change transmission direction, makes structure more succinct, also reduces failure rate simultaneously; 3, adopt ball screw, supporting power is big, helps improving service life; 4, adopt two groups of drive elements, adopt three or four to drive the limit, make driving more reliable and more stable, improve safety.
