Abstract
The invention discloses a double-column jacking device, which comprises a main vertical column, an auxiliary column, a driving chain and a slider, wherein the slider is driven by the driving chain. A first upper safety tongue, a second upper safety tongue, a first lower safety tongue and a second lower safety tongue are arranged on the upper portions and the lower portions of the main vertical column and the auxiliary vertical column at the same height. Preferably, the first lower safety tongue is arranged on the inner side of the main vertical column, and the second lower safety tongue is arranged on the inner side of the auxiliary vertical column. Since the lower portions and the upper portions of the two vertical columns are provided with the safety tongues, cars are protected at the low jacking position, and operation safety is guaranteed. Besides, the lower safety tongues are arranged on the inner sides of the vertical columns, so that the double-column jacking device is more attractive in appearance. Safety devices of common double-column jacking device are upgraded, and more powerful guarantee is provided for world market competitiveness of the double-column jacking device.
Description
Technical field
The present invention relates to a kind of vehicle maintenance and repair maintenance facility, relate in particular to a kind of double-column lifter.
Background technology
The safety control technology of double-column lifter lacks very much at present; The top at major and minor column that existing double-column lifter adopts mostly is provided with safety tongue; Have only when automobile rises to the safety tongue height, just get into safety position, so when lifting machine lifting low level; Automobile is in no safety position, like this there is potential safety hazard in the operative employee when operating.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, a kind of lifting machine that when the lifting low level, does not have potential safety hazard is provided.
Technical scheme: in order to realize above purpose; A kind of double-column lifter of the present invention; Comprise head tree, secondary column, messenger chain, come the gliding mass of transmission, be provided with first insure tongue, second insure tongue and first time safety tongue and second time safety tongue at the sustained height place of the upper and lower of said head tree and secondary column through messenger chain;
Wherein, first tongue of insuring that described head tree top is provided with is provided with handle, and described messenger chain one end connects described first tongue of insuring, and second tongue of insuring that the other end and secondary column top are provided with links to each other;
On the said head tree first insured and is connected through first connecting rod between tongue and the first time safety tongue, and second on the said secondary column insured and be connected through second connecting rod between tongue and the second time safety tongue.
Wherein, for product is more attractive in appearance, described first time safety tongue is preferably placed at the inboard of head tree, and said second time safety tongue is preferably placed at the inboard of secondary column.
Wherein, described messenger chain is steel rope or chain.
Beneficial effect: a kind of double-column lifter provided by the invention, be equipped with safety tongue on the bottom and the top of two columns, realized that automobile gets into the purpose of insurance when the lifting low level, guaranteed the safety of operation;
With descending safety tongue to be located at the inboard of column, more attractive in appearance; The present invention is simple to operate, has improved work efficiency with respect to loaded down with trivial details bilateral release, and in maintenance after sale more humane, simple and convenient than bilateral release; This product has improved a level on the safety device of common double-column lifter, occupy the competitive power of world market for double-column lifter and made more sound assurance.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, further illustrate the present invention.
To shown in Figure 13, a kind of double-column lifter comprises that head tree 1, secondary column 2, messenger chain 3 are steel rope (also can be chain), come the gliding mass 4 of transmission through steel rope like Fig. 1; Be provided with first insure tongue 51, second insure tongue 53 and first time safety tongue 52 and second time safety tongue 54 at the sustained height place of the upper and lower of said head tree 1 and secondary column 2.
Wherein, first tongue 51 of insuring that described head tree 1 top is provided with is provided with handle 6, and described messenger chain 3 one ends connect described first tongue 51 of insuring, and second tongue 53 of insuring that the other end and secondary column 2 tops are provided with links to each other.
On the said head tree 1 first insured and is connected through first connecting rod 512 between tongue 51 and the first time safety tongue 52, and second on the said secondary column 2 insured and be connected through second connecting rod 534 between tongue 53 and the second time safety tongue 54.
On described gliding mass 4, be provided with insurance bar 8, this insurance bar 8 is provided with draw-in groove 9 a plurality of and the safety tongue coupling, and this insurance bar 8 places between insuring of each column and the following insurance.
Insure and be provided with the spring that is used to reset on the tongue 53 at described first tongue 51 and second of insuring, be i.e. first spring 71 and second spring 73.
Described first time safety tongue 52 is positioned at the inboard of head tree 1, and said second time safety tongue 54 is positioned at the inboard of secondary column 2.
The present invention in use; When vehicle hoisting to the first time safety tongue 52 and second time safety tongue 54 height; Promptly get into safety position, be stuck in draw-in groove 9 through first time safety tongue 52 and second time safety tongue 54 safety tongue, automobile can be stopped at that each column is insured and any height between the insurance down; Convenient maintenance, and safety and stability; When automobile descends, following handle 6, insurance is opened; First the insure tongue 51 breaks away from draw-in groove 9 and descends; Drive first time safety tongue 52 through connecting rod 512 effect and descend,, drive second tongue 53 of insuring and break away from draw-in groove 9 and descend simultaneously through the gearing of steel rope; Drive second time safety tongue 54 through connecting rod 512 effects and descend, thus the decline of realization automobile; In this process,, safety tongue is stuck on the draw-in groove 9, thereby can cause personal injury the staff if unexpected fracture of steel rope or oil pipe explosion can be passed through action of reset spring.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
