As further program of the utility model: area ratio piston area of described No. two pistons is large.
As further program of the utility model: the material of described cushion rubber is elastomeric material.
As further program of the utility model: the height of described safety catch upper surface is higher than the height of jacking block.
As further program of the utility model: described pressure-strain sheet embedded pressure resistor wire.
As further program of the utility model: described alarm lamp is red LED lamp.
Compared with prior art, the beneficial effects of the utility model are: when needs jack-up weight, first weight is placed on Slave cylinder upper end, because the height of safety catch is higher than the height of jacking block, doing so avoids jacking block directly to contact with weight, thus avoid that weight is overweight to cause damage to device, described safety catch upper surface is provided with pressure-strain sheet, pressure-strain sheet embedded pressure resistor wire, adopt widely used two-wire system mode of connection in industry, resistance sizes in sheet is become by positive pressure Quorum Sensing, make output voltage and resistance substantially linear, by strain-gauge resistance signal through analogue to digital conversion, just can demonstrate jack lifting weight of object, described pressure-strain sheet connects alarm lamp, alarm lamp is provided with Signal-controlled switch, prescribe a time limit when the resistance (weight of object) on pressure-strain sheet exceedes on jack, Signal-controlled switch makes alarm lamp glimmer, thus effectively avoid overweight overload to the infringement of jack, improve the service life of device.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: base 1, piston 2, power hydraulic cylinder 3, safety catch 4, pressure-strain sheet 5, jacking block 6, cushion rubber 7, pillar stiffener 8, Slave cylinder 9, No. two pistons 10, contiguous block 11, oil guide pipe 12, No. two contiguous blocks 13, alarm lamps 14.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of hydraulic jack, comprise base 1, a piston 2, power hydraulic cylinder 3, safety catch 4, pressure-strain sheet 5, jacking block 6, Slave cylinder 9, No. two pistons 10 and alarm lamp 14, described base 1 upper right side is provided with power hydraulic cylinder 3, a piston 2 is provided with in power hydraulic cylinder 3, No. two contiguous blocks 13 are provided with bottom power hydraulic cylinder 3, described base 1 left upper end is provided with Slave cylinder 9, Slave cylinder 9 lower end is provided with a contiguous block 11, oil guide pipe 12 is provided with between a contiguous block 11 and No. two contiguous blocks 13, No. two pistons 10 are provided with in Slave cylinder 9, area ratio piston 2 area of No. two pistons 10 is large, No. two piston 10 upper ends are provided with pillar stiffener 8, pillar stiffener 8 upper end is provided with jacking block 6, jacking block 6 upper surface is provided with cushion rubber 7, the material of cushion rubber 7 is elastomeric material, the effect of cushion rubber 7 avoids weight directly to contact with jacking block 6, thus improve the service life of jacking block 6, Slave cylinder 9 upper end of described jacking block 6 both sides is provided with safety catch 4, the height of safety catch 4 upper surface is higher than the height of jacking block 6, when needs jack-up weight, first weight is placed on Slave cylinder 9 upper end, because the height of safety catch 4 is higher than the height of jacking block 6, doing so avoids jacking block 6 directly to contact with weight, thus avoid that weight is overweight to cause damage to device, described safety catch 4 upper surface is provided with pressure-strain sheet 5, pressure-strain sheet 5 embedded pressure resistor wire, adopt widely used two-wire system mode of connection in industry, resistance sizes in sheet is become by positive pressure Quorum Sensing, make output voltage and resistance substantially linear, by strain-gauge resistance signal through analogue to digital conversion, just can demonstrate jack lifting weight of object, described pressure-strain sheet 5 connects alarm lamp 14, alarm lamp 14 is red LED lamp, alarm lamp 14 is provided with Signal-controlled switch, prescribe a time limit when the resistance (weight of object) on pressure-strain sheet 5 exceedes on jack, Signal-controlled switch makes alarm lamp 14 glimmer, thus effectively avoid overweight overload to the infringement of jack, improve the service life of device.
