Abstract
The utility model relates to a novel hydraulic jack which is characterized in that the hydraulic jack is provided with an oil conduit for sucking oil (1), wherein, the top part of the oil conduit for sucking oil (1) is communicated with an oil storing chamber (3) through a ball check valve (2), and the root part of the oil conduit for sucking oil (1) is communicated with an oil sucking passage (5). A weight meter for representing the hoisting weight (9) is connected with a high-pressure oil chamber (4) through an oil passage (7). Compared with the common hydraulic jacks, the utility model has the advantage that the hydraulic jack can weigh in the definite range and can be used in the reverse and transverse modes besides hoisting function.
Description
The utility model relates to a kind of hydraulic jack that still can count heavy and inversion, horizontal use except that can be used as lifting, belongs to the lifting gear technical field.
At present, general hydraulic jack is pressed the compositions such as base, piston cylinder, piston bush, screw rod and hand piston pump of oil duct and draining oil duct by having the oil suction oil duct.Back and forth lift hand piston pump during work, the oil suction check valve ball is opened when plunger makes progress, and presses oily check valve ball to close, and at this moment sucks fluid to pump from oil storage chamber; The oil suction check valve ball was closed and is pressed oily check valve ball to open when plunger was downward, and the pump inner fluid enters high pressure chest through pressing oil duct, promotes piston bush upwards, thereby reaches the purpose of lifting.This simple lifting gear since its structure light and handy, move conveniently, safeguard easily, thereby be widely used.When adjustable height was little, hydraulic jack can be in order to heavy zero, the parts of lifting.Hydraulic jack also usually is used to press-fit related parts, to the aligning of workpiece and carry out other erection work.General hydraulic jack do not possess the heavy function of meter and can not be inverted, horizontal use.
The purpose of this utility model is to do further to improve at above-mentioned hydraulic jack, it can be counted again heavily in lifting, and can realize the purpose of inversion, horizontal use under special operation condition.
Main points of the present utility model are to be provided with the oil suction oil pipe (1) that can communicate with oil storage chamber (3) and oil suction oil duct (5) in general hydraulic jack, pick out a meter of being made up of pipe spring element, gear, lever and dial plate etc. from high-voltage oil cavity (4) by oil duct (7) and heavily show (9).
Of the present utility model being characterised in that, hydraulic jack are provided with the top and the oil suction oil pipe (1) that check valve ball (2) communicates with oil storage chamber (3), root communicates with oil suction oil duct (5) are housed and count heavily table (9).
Said meter is heavily shown (9) and is inserted high-voltage oil cavity (4) by oil duct (7), and the meter heavily dial plate of table can be indicated lifting weight.Lifting weight is determined by the product of piston area and high-voltage oil cavity oil liquid pressure, can be counted the design of heavily showing dial scale according to this relation.
For realize being inverted, the purpose of horizontal use, the volume of oil storage chamber (3) should be greater than the twice of the volume of high-voltage oil cavity (4), like this, no matter be normal use or be inverted, horizontal use, can both make high-voltage oil cavity suck enough fluid, guarantee the hydraulic jack normal operation from oil storage chamber.
The utility model is heavily shown with meter owing to increased the oil suction oil pipe on the basis of general hydraulic jack original structure, so can count the purpose that weighs and realize inversion, horizontal use within the specific limits.
Accompanying drawing 1, Fig. 2 are the scheme drawing of novel hydraulic jack.
Among the figure: (1) oil suction oil pipe (2) check valve ball (3) oil storage chamber (4) high-voltage oil cavity (5) oil suction oil duct (6) is pressed heavily table (10) shell (11) filler plug of oil duct (7) oil duct (8) the heavy meter connector of meter (9) meter
