[specific embodiment]
Refering to fig. 1 and Fig. 2, a kind of emergency support of hydraulic jack of the present invention, including rack body 1, bracket base 2,
The bottom of fixed block 3, support rod 4, sawtooth 5, gear 6 and bearing base 7, rack body 1 is equipped with bracket base 2, bracket base 2
Top is equipped with fixed block 3, and the internal vertical of fixed block 3, which runs through, is equipped with support rod 4, and the side of support rod 4 is equipped with several sawtooth 5,
Fixed block 3 is equipped with gear 6 close to the side of sawtooth 5, and the top of support rod 4 is equipped with bearing base 7.
Wherein, gear 6 is located at the outside of sawtooth 5, is meshed between sawtooth 5 and gear 6, and support rod 4 is completed in the two cooperation
Lifting.
Wherein, the cross sectional shape of bearing base 7 is Y shape, and the edge of bearing base 7 is all made of round and smooth processing, prevents weight and hold
The contact of weight seat 10 generates abrasion.
Wherein, the top center of bearing base 7 is equipped with recess 8, and the top two sides of bearing base 7 are equipped with non-slip mat 9, improve load-bearing
The structural stability of seat 10 avoids bearing base 10 from damaging, and improves non-skid property, prevents positional shift.
Wherein, retaining beam 10 is equipped on fixed block 3, retaining beam 10 is corresponding with the wave mouth of sawtooth 5 to coincide.
Wherein, bracket base 2 is pyramid-shaped structures, improves the stability of rack body 1.
Wherein, bracket base 2 uses integral molding techniques, is realized admittedly between bracket base 2 and fixed block 3 by welding
It is fixed, improve the stability of bracket base 2 and fixed block 3.
Wherein, support rod 4 is rectangular parallelepiped structure, and support rod 4 is structure as a whole with bearing base 7, improves support rod 4 and load-bearing
Stability between seat 7.
When rising bracket, every section wave mouth of square tube rack gear opens retaining beam and persistently rises, stable structure, even if occurring tight
Anxious whereabouts situation, the downward opening wave mouth retaining of retaining beam clamping, can avoid contingency occur, highly-safe
The course of work of the present invention: when lifting weight, bearing base 10 is placed on the fixed of weight and lifted by mobile rack body 1
Bearing base 7 is lifted upwards by external jack, weight is jacked up upwards, drives support rod 4 solid by the lower section that raise-position is set
Determine to move upwards in block 3, sawtooth 5 opens retaining beam 10, and with 6 engagement rotation of gear, stable structure passes through 7 top of bearing base
The structural strength of bearing base 7 can be improved in recess 8, damage bearing base 8 when avoiding weight overweight, the non-slip mat 9 on bearing base 8,
The frictional behaviour between weight and bearing base 9 is improved, non-skid property can be improved, prevent positional shift, it is urgent when occurring
When the case where whereabouts, downward opening 5 retaining of sawtooth of 10 clamping of retaining beam can avoid contingency occur, highly-safe.
A kind of emergency support of hydraulic jack of the present invention during the work time, by setting gear 6 and sawtooth 5, passes through
