Problems solved by technology
[0004] The above-mentioned horizontal hydraulic jack has the disadvantage of using a longer piston rod to meet the stroke requirements, because, as mentioned above, the positive push horizontal hydraulic jack relies on the cylinder column of the oil cylinder to lift the boom, so, The back of the base where the cylinder is set must leave enough space to allow the cylinder to be set
In addition, the hydraulic parts of the horizontal hydraulic jack with the above-mentioned structure are easily damaged due to lack of proper protection, because dust, foreign matter, water, moisture, etc. on the job site can easily attack the piston rod, and when the piston rod is subjected to other Objects cannot be effectively protected or cushioned when they hit

The invention discloses a horizontal type hydraulic jack and belongs to the technical field of lifting equipment. The horizontal type hydraulic jack comprises a base, an oil cylinder, an operating handle and a hoist frame and is characterized in that: a piston rod sleeve fixing plate is arranged at one end, facing a pair of front wheels, of the base and positioned in a base cavity; a piston rod seat sleeve is arranged on one side, facing a piston rod, of the piston rod sleeve fixing plate; the piston rod is connected with the piston rod seat sleeve; one end of a tension spring is fixed on thepiston rod sleeve fixing plate and the other end of the tension spring is fixed on an oil cylinder seat; the oil cylinder seat is provided with a pair of oil cylinder seat arms; the pair of oil cylinder seat arms stretch towards a direction of a pair of rear wheels of the base; the hoist frame and the operating handle are coaxially hinged on the pair of oil cylinder seat arms; an oil pump is arranged on the oil cylinder seat; a load bearing mechanism is hinged with one end, facing one end of the pair of the front wheels, of the hoist frame and also hinged with one end, facing one end of the pair of front wheels, of a pair of pull rods; and one end, facing the pair of rear wheels, of the hoist frame is hinged with the base. The horizontal type hydraulic jack has the advantages of increasing the hoisting height of the jack, preventing impurities such as dust, steam and the like from invading the piston rod and preventing an oil cylinder from being damaged.
