Abstract
The utility model discloses an oil absorption eccentric quick transmission mechanism of a jack. The oil absorption eccentric quick transmission mechanism of the jack comprises a pump core, an upright post and an eccentric transmission piece, wherein the eccentric transmission piece is connected to the upright post; and the eccentric transmission piece is connected with the upper end of the pump core. By adoption of the transmission mechanism, oil absorption and oil discharge can be finished quickly, the jack can be lifted quickly; and the work efficiency of the jack is improved.
Description
Technical field
The utility model relates to a kind of cam drive of jack, the eccentric fast speed driving mechanism of a kind of oil suction of jack specifically.
Background technology
The fluid pressure type jack structure is compact, and stable working has self-locking action, so use extensively.But the oil suction pump body portion of existing jack, delivery rate is too slow during because of zero load, process is slower so that jack hoists, and this shortcoming especially embodies more obviously on the large-tonnage jack.Such as: 12 tons of vertical oil jacks, the time that hoists when unloaded needs about 2 minutes, inefficiency.
Summary of the invention
The utility model technical matters to be solved is to propose that a kind of lifting velocity is fast, the eccentric fast speed driving mechanism of the oil suction of the jack of high efficiency.
For solving the problems of the technologies described above, the eccentric fast speed driving mechanism of the oil suction of a kind of jack of the utility model comprises pump core, column and eccentric drive part, and said eccentric drive part is connected on the said column, and said eccentric drive part links to each other with the upper end of said pump core.
The eccentric fast speed driving mechanism of the oil suction of above-mentioned a kind of jack; Said eccentric drive part comprises two power wheels and transmission shaft; Said column has two; Said two power wheels are connected on two said columns, and the two ends of said transmission shaft off-centre respectively are fixed on said two power wheels, and the centre of said transmission shaft is set in the set cavity in said pump core upper end.
The eccentric fast speed driving mechanism of the oil suction of above-mentioned a kind of jack; Said eccentric drive part is " several " font bent axle; Said column has two, and the two ends of said bent axle are connected on the said column, and the intermediate projections of said bent axle partly is set in the cavity of the set upper end of said pump core.
The eccentric fast speed driving mechanism of the oil suction of above-mentioned a kind of jack, said eccentric drive part comprises cam and transmission shaft, and said cam is fixed on the said support through said transmission shaft, and said cam places on the set platform in said pump core upper end.
The utility model, links to each other with the eccentric drive part with wind spanner (twirl instruments such as the also available power-operated wrench of wind spanner, manual wrench replace) during use owing to adopted above-mentioned technical pattern.Start the wind spanner, drive the eccentric drive part and rotate, and then drive the pump core and do and pump, so just can accomplish oil suction, fuel-displaced action very quickly, jack is hoisted apace, improved the work efficiency of jack.Be example with 12 tons of vertical oil jacks equally, the time that hoists when unloaded only needs 12 seconds, high efficiency.

The specific embodiment
As shown in Figure 1; The eccentric fast speed driving mechanism of the oil suction of the utility model jack comprises pump core 1, column 2 and eccentric drive part; Column 2 has two; The top of pump core 1 is U-shaped cavity (please consulting Fig. 2 simultaneously), and the eccentric drive part comprises preceding power wheel 5, back power wheel 6 and transmission shaft 4, and forward and backward power wheel 5,6 is connected (bearing 3 is located in the macropore set on the column 2) on two root posts 2 through bearing 3 respectively.The two ends off-centre of transmission shaft 4 is welded on pre-eccentric wheel 5 and the back eccentric wheel 6, and the centre of transmission shaft 4 is set in the U-shaped cavity of pump core 1 upper end.During installation, column 2 is fixed on the base of jack, and pump core 1 is located in the oil suction pump housing of jack.During use, be sheathed on pre-eccentric with wind spanner (twirl instruments such as the also available power-operated wrench of wind spanner, manual wrench replace) and take turns (attaching parts of shapes such as also available four jiaos of hexagonal nut, triangle, homalocephalus, flat recess, cross recess replaces) on the hexagonal nut of 5 front ends.Start the wind spanner, drive pre-eccentric wheel 5, transmission shaft 4 and back eccentric 6 and rotate.Because of the two ends of transmission shaft 4 are welded in respectively on pre-eccentric wheel 5 and the back eccentric wheel 6, so transmission shaft 4 can drive sheathed pump core 1 above that and do and pump, thereby can accomplish oil suction, fuel-displaced action very quickly, the jacking jack hoists fast.
As shown in Figure 3, the eccentric drive part is " several " font bent axle 7, and the two ends of bent axle 7 are fixedly connected on respectively on the column 2, and the intermediate projections of bent axle 7 partly is set in the U-shaped cavity of pump core 1 upper end.During use, the external side end 71 of bent axle 7 links to each other with power take-off mechanism.
Like Fig. 4 and shown in Figure 5, different with preceding two embodiments, pump core 1 oil suction automatically has a platform 12 in the welded top of pump core 1.The eccentric drive part comprises cam 8 and transmission shaft 9, and cam 8 is fixed on the support 2 through transmission shaft 9 and bearing 3, and cam 8 places on the platform 12 of pump core 1 upper end.During use, the external side end 91 of transmission shaft 9 links to each other with power take-off mechanism.Cam 8 rotates on platform 12 just can accomplish oil suction, fuel-displaced.
