Description
Technical field
The utility model relates to a kind of fast lifting machine of scissors lift bench.
Background technology
Scissors lift bench is also called hydraulic jack or shearing type lifter, and it drives lifting by hydraulic efficiency pressure system, plays vital effect keeping in repair in particularly vehicle maintenance and repair maintenance.
But, traditional small-sized scissors lift bench be a kind of oil cylinder directly act under scissors platform panel along or the lower end that acts on scissors mechanism cut on bar, in any case layout, the lifting velocity of platform panel is slow, its key reason is: this series products relies on manual type pin to step on oil cylinder to make the speed of stretching out of lift oil tank output shaft slow, and what determine that it can not rise is very fast.
Fig. 1 is the scissors platform truck that a kind of lift oil tank acts directly on platform panel, and what the speed V ' that clearly its platform panel rises equaled the piston rod of lift oil tank stretches out speed V ' '.
Fig. 2 is that a kind of lift oil tank is arranged in the in-house structure of scissors, and Fig. 3 is the velocity analysis figure of Fig. 2, ascending velocity V '=V ' ' the sin θ of platform panel.
Therefore, the lifting velocity of the scissors lift bench of conventional confguration is slow, requires further improvement and optimizes.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of fast lifting machine of scissors lift bench, and its structure is simple, and platform panel lifting velocity is fast.
The utility model solves the technical scheme that its technical matters adopts:
A kind of fast lifting machine of scissors lift bench, comprise frame, described frame is provided with scissors mechanism and lift oil tank, the top of scissors mechanism is platform panel, the take-off lever end of described lift oil tank is provided with movable pulley, described movable pulley is wound with chain, and one end of chain and the bar of cutting of described scissors mechanism are connected and fixed, and the cylinder body of the other end and lift oil tank is connected and fixed.
As the improvement of technique scheme, described lift oil tank is arranged vertically, and described frame is provided with fixed pulley, is connected and fixed after fixed pulley walked around by described chain with described bar of cutting.
Another kind as technique scheme improves, described lift oil tank horizontal arrangement.
Further, described frame is provided with the pin controlling lift oil tank work and steps on hydraulic cylinder assembly.
Further, described frame is provided with the roller being convenient to lifting machine movement.
Preferably, described roller is cardan wheel.
The beneficial effects of the utility model are: the utility model adopting said structure, lift oil tank and chain is coordinated by movable pulley, platform panel lifting velocity is significantly promoted, achieve the amplification that lift oil tank stretches out speed, improve the work efficiency of scissors lift bench, be conducive to the use cost reducing user, be applicable to replacing existing scissors lifting machine.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
With reference to Fig. 4 ~ Fig. 7, the fast lifting machine of a kind of scissors lift bench of the present utility model, comprise frame 1, described frame 1 is provided with scissors mechanism 2 and lift oil tank 3, the top of scissors mechanism 2 is platform panel 21, and the take-off lever end of described lift oil tank 3 is provided with movable pulley 4, and described movable pulley 4 is wound with chain 6, one end of chain 6 and the bar 22 of cutting of described scissors mechanism 2 are connected and fixed, and the cylinder body of the other end and lift oil tank 3 is connected and fixed.
As embodiment 1 of the present utility model, described lift oil tank 3 is arranged vertically, and described frame 1 is provided with fixed pulley 5, is connected and fixed after fixed pulley 5 walked around by described chain 6 with described bar 22 of cutting.
See Fig. 5, first with movable pulley 4 for research object, because movable pulley 4 is plane motions, its instantaneous point is A, therefore V ' '=ω R, and wherein ω is cireular frequency, R is the radius of movable pulley 4, V ' ' '=ω 2R, so V ' ' '=2V ' ', 2 times of the piston rod ascending velocity V ' ' that in this mechanism, the kinematic velocity V ' ' ' of chain 6 is lift oil tank 3.
See Fig. 6, to cut bar MN for research object, its movement relation is as follows: V '=V ' ' ' tg θ=2V ' ' tg θ, which achieves the object that V ' amplifies.
As embodiment 2 of the present utility model, described lift oil tank 3 horizontal arrangement, shown in Figure 7, make a concrete analysis of same embodiment 1, repeat no more herein.
In the above-described embodiments, described frame 1 is provided with the pin controlling lift oil tank 3 work and steps on hydraulic cylinder assembly 7, utilize known pin to step on hydraulic cylinder assembly 7 and work to control lift oil tank 3, handled easily.
In the above-described embodiments, for ease of lifting machine transfer, described frame 1 is provided with the roller 8 being convenient to lifting machine movement, described roller is preferably cardan wheel.
In sum, when lifting machine hoists, chain 6 pulls the bar MN that cuts in scissors structure to make plane motion with the speed that 2 times are stretched out to lift oil tank piston rod, make platform panel ascending velocity V '=2V ' ' the tg θ on device for rod cutting structure 2 top, lifting velocity increases 2 tg θ doubly relative to the conventional confguration shown in Fig. 1 and Fig. 2.During whereabouts, the take-off lever retraction chain playback of lift oil tank, whereabouts propulsive effort is by deadweight.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches the utility model art effect with any same or similar means, all should fall within protection domain of the present utility model.
