Problems solved by technology

But the oil-absorbing pump body part of the existing jack, because the oil supply speed is too slow when it is no-load, so that the lifting process of the jack is slow, and this shortcoming is more obvious especially on the large-tonnage jack
For example: 12 tons of vertical hydraulic jack, it takes about 2 minutes to lift when it is empty, and the work efficiency is low

Embodiment Construction

[0014] Such as figure 1 As shown, the oil-absorbing eccentric fast transmission mechanism of the jack of the present invention includes a pump core 1, a column 2 and an eccentric transmission member, and there are two columns 2, and the top of the pump core 1 is a U-shaped cavity (see also figure 2 ), the eccentric transmission parts include the front transmission wheel 5, the rear transmission wheel 6 and the transmission shaft 4, the front and rear transmission wheels 5, 6 are respectively connected to the two columns 2 through the bearing 3 (the bearing 3 is set on the column 2 in the large hole). Both ends of the transmission shaft 4 are eccentrically welded on the front eccentric wheel 5 and the rear eccentric wheel 6 , and the middle of the transmission shaft 4 is sleeved in the U-shaped cavity at the upper end of the pump core 1 . During installation, the column 2 is fixed on the base of the jack, and the pump core 1 is arranged in the oil suction pump body of the jac...

Abstract

The invention discloses an oil-absorbing eccentric quick transmission mechanism for a jack. The transmission mechanism comprises a pump core, an upright column and an eccentric transmission piece, wherein the eccentric transmission piece is connected with the upright column and is connected with the upper end of the pump core. The transmission mechanism provided by the invention can be utilized to quickly finish the oil-absorbing and oil-discharging operations, so that the jack can be quickly lifted and the working efficiency of the jack can be increased.

Description

technical field [0001] The invention relates to a cam transmission mechanism of a jack, in particular to an oil-absorbing eccentric fast transmission mechanism of a jack. Background technique [0002] The hydraulic jack has compact structure, stable operation and self-locking effect, so it is widely used. But the oil-absorbing pump body part of the existing jack, because the oil supply speed is too slow when no-load, so that the jack lifting process is relatively slow, this shortcoming especially embodies more obviously on the jack of large tonnage. For example: 12 tons of vertical hydraulic jack, it takes about 2 minutes to lift when it is empty, and the work efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil-absorbing eccentric fast transmission mechanism of the jack with fast lifting speed and high working efficiency. [0004] In order to solve the above-mentioned technical problems, a...
