Abstract

The utility model relates to the technical field of thrust oil cylinders in a hydraulic technology, in particular to a double-tapping large-travel oil cylinder comprising oil cylinder bodies, pistons and piston rods, wherein the piston rods are connected on the pistons, the pistons and the piston rods are both arranged in the oil cylinder bodies, and the oil cylinder is formed by combining two common double-acting oil cylinder bodies. The combination mode of the two oil cylinder bodies is parallel opposite combination. The rodless cavities of the two oil cylinder bodies are communicated, and the rod cavities of the two oil cylinder bodies are also communicated. The travel of the oil cylinder is 2 times of the travel of a common oil cylinder under a common equivalent environment. Meanwhile, the structure is compact, the installation space is decreased, and the control accuracy is high.

Description

Twoly lift one's head big stroke oil cylinder
Technical field
The utility model relates to the push action cylinder technical field in the hydraulics, especially a kind of two big stroke oil cylinders of lifting one's head.
Background technique
In this Innovation-oriented Society, hydraulic equipment is constantly weeded out the old and bring forth the new, and by traditional design concept, can make the small volume oil cylinder with the method for multi-stage oil cylinder and ratio adjusting valve combination, realizes function substantially.But in ratio is regulated, not only to regulate flow and also will regulate pressure, in pressure and flow cycled process, will inevitably produce the phenomenon that lags behind or impact, be difficult to guarantee that in demanding occasion oil cylinder stroke is the conformity of linear output and oil cylinder total travel ouput force.
The model utility content
In order to overcome the deficiency of existing compact type two-way cylinder low precision, defectives such as processing cost height, the utility model provides a kind of two big stroke oil cylinder of lifting one's head.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of two big stroke oil cylinders of lifting one's head, comprise cylinder body, piston and piston rod, piston rod is connected on the piston, and piston and piston rod all place in the cylinder body, and this oil cylinder is combined by two common double effect cylinder bodies.
The compound mode of two cylinder bodies is combination in opposite directions side by side.
The rodless cavity of two cylinder bodies is connected, and rod chamber is also connected.
The beneficial effects of the utility model are, oil cylinder stroke is 2 times of common oil cylinder stroke under the general equal environment, and the oil cylinder ouput force has the characteristic of common two-way cylinder concurrently, and power and speed that oil cylinder is exported under the constant situation of pressure flow when operation are constant.The while compact structure, installing space reduces, the control accuracy height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic representation of the present utility model.
1. cylinder bodies among the figure, 2. piston, 3. piston rod.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is schematic representation of the present utility model, a kind of two big stroke oil cylinder of lifting one's head comprises cylinder body 1, piston 2 and piston rod 3, and piston rod 3 is connected on the piston 2, piston 2 and piston rod 3 all place in the cylinder body 1, and this oil cylinder is combined by two common double effect cylinder bodies 2.The compound mode of two cylinder bodies 2 is combination in opposite directions side by side.The rodless cavity of two cylinder bodies 2 is connected, and rod chamber is also connected.
During work, two cylinder body 1 interior pistons 2 are done in opposite directions or opposing motion, make stroke meet the demands, the while compact structure, installing space reduces, be used for all kinds of hydraulic machinery industries that stroke is long, mounting distance is little and output is linear stable that need, especially very wide application prospect arranged in engineering machinery field.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
