Abstract
The utility model relates to a hydraulic pulling device, which aims at solving the defects of the prior art. The hydraulic pulling device comprises a high-pressure oil pipe, and is characterized in that the upper end of the high-pressure oil pipe is provided with a vessel and an oil cylinder, the upper end of the vessel is provided with a hand-operated plunger pump, an inlet of the hand-operated plunger pump is connected into the vessel, an outlet of the hand-operated plunger pump is connected with the high-pressure oil pipe, the high-pressure oil pipe is also provided with a hand-operated pressure releasing valve, two ports of the oil cylinder are respectively provided with a hook, and a piston rod end of the oil cylinder is provided with an oil inlet which is connected with the high-pressure oil pipe. The hydraulic pulling device is simple in structure and safe to use, as long as the hand-operated plunger pump is pulled in work to pump oil into the oil cylinder, under the pressure effect of the oil, a piston rod of the oil cylinder is withdrawn, so that objects are pulled to be close to each other.
Description
Technical field
The utility model relates to a kind of hydraulic pressure chest expander.
Background technology
People are doing when work industry, often to use two objects each other near, in this time, people can adopt chain block or machinery to draw the Malaysia to carry out work, but adopt such equipment, can cause strength not enough, have increased the difficulty of people when work.
Summary of the invention
The purpose of the utility model provides a kind of hydraulic pressure chest expander, and it mainly solves existing technology and has weak point.The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals.
A kind of hydraulic pressure chest expander of the utility model comprises high-pressure oil pipe, it is characterized in that described high-pressure oil pipe upper end is provided with a container and an oil cylinder; Upper end at container is provided with hand piston pump; The import of hand piston pump connects the inside of container, and its outlet connects high-pressure oil pipe, on high-pressure oil pipe, also is provided with the Manual pressure relief valve; And respectively establish a drag hook at two ports of oil cylinder, be provided with an oil-in at the tailpiece of the piston rod of oil cylinder and be connected with high-pressure oil pipe.
The utlity model has simple in structurely, safe in utilization, as long as people press hand piston pump in when work, in oil cylinder, buy oil, oil cylinder receives under the pressure effect of oil, makes the piston rod retraction of oil cylinder, thus the pulling object each other near.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing that the technical scheme of the utility model is further specified.
Embodiment, as shown in Figure 1, a kind of hydraulic pressure chest expander of this example; Comprise high-pressure oil pipe 1, be provided with a container 2 and an oil cylinder 3 in high-pressure oil pipe 1 upper end, be provided with hand piston pump 4 in the upper end of container 2; The import of hand piston pump 4 connects the inside of container 2, and its outlet connects high-pressure oil pipe 1, on high-pressure oil pipe 1, also is provided with Manual pressure relief valve 5; And respectively establish a drag hook 6 at two ports of oil cylinder 3, be provided with an oil-in 7 at the tailpiece of the piston rod of oil cylinder 3 and be connected with high-pressure oil pipe 1.
During use, as long as people press hand piston pump in when work, in oil cylinder, buy oil, oil cylinder receives under the pressure effect of oil, makes the piston rod retraction of oil cylinder, thus the pulling object each other near.
