Abstract
Disclosed is a movable hydraulic puller which comprises a hydraulic drawing device and a lifting and moving device. The lifting and moving device is provided with a bracket with a roller, a hydraulic oil cylinder and a group of transmission rods arranged on the bracket, which exist in the prior art. A piston rod connected with the transmission rods is arranged in the hydraulic cylinder. A pressure adding handle is arranged on the hydraulic cylinder. The transmission rods are connected with the hydraulic drawing device which includes a hydraulic cylinder and a group of draw hooks fixed on the hydraulic cylinder. A piston is arranged inside the hydraulic cylinder of the drawing device. A pressure adding handle and a decompression valve are arranged inside the hydraulic cylinder of the drawing device. Compared with the prior art, the hydraulic puller can be moved optionally and the height of the hydraulic puller can be changed due to the lifting and moving device. The utility model is easy to use and is not limited by sites.
Description
Technical field:
The utility model relates to a kind of hand-operated tools, and specifically a kind of hand-hydraulic instrument that is used to dismantle part especially, is a kind of movably being used for from the manual hydraulic drawing horse of axle dismounting wheel-like bodies.
Background technology:
Available technology adopting manual hydraulic drawing horse is dismantled wheel-like bodies from axle, and hydraulic pressure draws saddlery that a fixed support is arranged.
Summary of the invention:
The technical problems to be solved in the utility model is: because available technology adopting manual hydraulic drawing horse is dismantled wheel-like bodies from axle, hydraulic pressure draws saddlery that a fixed support is arranged, so the inconvenience of carrying is subjected to the restriction in place, does not have the effect of regulating height simultaneously.The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to provide a kind of mobile hydraulic and draw horse, wherein, described this mobile hydraulic draws horse to comprise a hydraulic pressure draw-off gear and a lifting and moving device, described lifting and moving device comprises a support that has roller, hydraulic jack and one group of drive link in prior art that is arranged on the described support, be provided with a piston rod in the described hydraulic jack, described piston rod connects described drive link, described hydraulic jack is provided with a pressurized handgrip, described drive link connects described hydraulic pressure draw-off gear, described hydraulic pressure draw-off gear comprises a hydraulic jack and one group of drag hook that is fixed on the hydraulic jack, in described hydraulic jack, be provided with a piston, on described hydraulic jack, also be provided with a pressurized handgrip and a pressure-reducing valve.Its course of work is the handle on the hydraulic jack in the operation lifting moving mechanism, increase the pressure in the oil cylinder, promotion is arranged on the piston rod on this oil cylinder, the piston rod elongation, the drive link that will be connected with piston rod lifts, thereby with the lifting of hydraulic pressure draw-off gear, after discharging the pressure in the hydraulic jack, piston rod retreats, described drive link drives the hydraulic pressure draw-off gear and descends, and promotes support, and whole device is moved to any horizontal direction by means of roller, pressurized handgrip on the hydraulic jack in the operation hydraulic pressure draw-off gear, pressure in the hydraulic jack is increased, described drag hook is hooked the opposite side of the part that needs dismounting, the piston in the hydraulic jack stretches out, act on by the front end face of the axle that draws object to install, when pressure continues to increase the part of required dismounting is pulled out from its installation shaft.By the pressure-reducing valve in the hydraulic jack in the hydraulic pressure draw-off gear.Can discharge the pressure in the hydraulic jack, piston rod can the spring action in being arranged on hydraulic jack under return, the utility model and prior art contrast, because adopted lifting and moving device, so can make hydraulic pressure draw horse arbitrarily to move and the change height, thereby convenient the use do not limited by or not the place.
Description of drawings:
Fig. 1 is the structural representation that a kind of mobile hydraulic of the utility model draws horse.
The specific embodiment:
As shown in Figure 1, a kind of mobile hydraulic of the utility model draws horse, comprise a hydraulic pressure draw-off gear 1 and a lifting and moving device 2, described lifting and moving device 2 comprises a support 21 that has roller, hydraulic jack 22 and one group of drive link 23 in prior art that is arranged on the described support 21, be provided with a piston rod 24 in the described hydraulic jack 22, described piston rod 24 connects described drive link 23, described hydraulic jack 22 is provided with a pressurized handgrip 25, described drive link 23 connects described hydraulic pressure draw-off gear 1, described hydraulic pressure draw-off gear 1 comprises a hydraulic jack 11 and one group of drag hook 12 that is fixed on the hydraulic jack 11, in described hydraulic jack 11, be provided with a piston 13, on described hydraulic jack 11, also be provided with a pressurized handgrip 14 and a pressure-reducing valve 15.Its course of work is the pressurized handgrip 25 on the hydraulic jack 22 in the operation lifting moving mechanism 2, increase the pressure in the hydraulic jack 22, promotion is arranged on the piston rod 24 on this hydraulic jack 22, piston rod 24 elongations, the drive link 23 that will be connected with piston rod 24 lifts, thereby with 1 lifting of hydraulic pressure draw-off gear, after discharging the pressure in the hydraulic jack 22, piston rod 24 retreats, described drive link 23 drives hydraulic pressure draw-off gear 1 and descends, promote support 21, whole device is moved to any horizontal direction by means of roller 26, pressurized handgrip 14 on the hydraulic jack 11 in the operation hydraulic pressure draw-off gear 1 can make the pressure in the hydraulic jack 11 increase, and described drag hook 12 is hooked the opposite side of the part that needs dismounting, piston 13 in the hydraulic jack 11 stretches out, act on by the front end face of the axle that draws object to install, when pressure continues to increase, the part of required dismounting is pulled out from its installation shaft.By the pressure-reducing valve in the hydraulic jack in the hydraulic pressure draw-off gear 1 11 15.Can discharge the pressure in the hydraulic jack 11, piston rod 13 can be under the spring action in being arranged on hydraulic jack 11 return, the utility model and prior art contrast, because adopted lifting and moving device 2, so can make hydraulic pressure draw horse arbitrarily to move and the change height, thereby convenient the use do not limited by or not the place.
