Abstract
The utility model discloses a kind of electricity to surge push-and-pull device; form primarily of cylinder body, oil pump and motor; oil pump is inputted by the driving of motor or is extracted hydraulic oil in cylinder body; suitable piston and piston rod is provided with in cylinder body; oil pump is provided with hydraulic manifold block; hydraulic manifold block is provided with relief valve; operationally; as piston rod the over proof ouput force of external force of bearing or piston rod reached range time; motor is still in work; relief valve can overflow rapidly and accurately, make oil pressure keep the pressure set up, thus protection motor is not burnt.
Description
Technical field
The utility model discloses a kind of push-and-pull device, refer more particularly to the push-and-pull device that electricity surges.
Background technique
Push-and-pull device is applicable to reciprocating linear push-and-pull campaign, can be used for the place rising, decline or clamp working substance, now being widely used in the departments such as metallurgy, mine, coal, electric power, machinery, grain, cement, chemical industry, water conservancy, transport, is indispensable general dynamic source.Electrohydraulic push rod take motor as power source, by motor just (instead) to rotation, make hydraulic oil by double-direction gearpump pressure oil output, through oil-way integrated block, deliver to operating cylinder, realize the to-and-fro motion of piston rod.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of electricity with overload self-protection function and surges push-and-pull device.
In order to solve the problems of the technologies described above, the utility model provides a kind of electricity and to surge push-and-pull device, form primarily of cylinder body, oil pump and motor, described oil pump is inputted by the driving of motor or is extracted hydraulic oil in cylinder body, suitable piston and piston rod is provided with in described cylinder body, described oil pump is provided with hydraulic manifold block, and described hydraulic manifold block is provided with relief valve.
As further improvement of the utility model, described oil pump is provided with air valve and observation panel.
As further improvement of the utility model, described piston is provided with seal ring.
As further improvement of the utility model, described piston rod end is provided with joint.
As further improvement of the utility model, described cylinder ends is provided with the guide sleeve suitable with piston rod.
Adopt said structure, its beneficial effect is: the hydraulic manifold block in this device oil pump is provided with relief valve, operationally, as piston rod the over proof ouput force of external force of bearing or piston rod reached range time, motor is still in work, relief valve can overflow rapidly and accurately, make oil pressure keep the pressure set up, thus protection motor is not burnt; Oil pump is provided with air valve and observation panel, to observe in pump whether bubble, the air that can enter in oil pump is discharged, and ensures the stability of oil pressure in pump; Cylinder body inner carrier is provided with seal ring, prevents leakage of oil from producing actual ouput force and theoretical ouput force produces error; Cylinder ends is provided with the guide sleeve suitable with piston rod, ensures that piston rod carries out push-and-pull campaign with rectilinear direction, makes push-pull effort according to ideal orientation effect.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of the electric push-and-pull device that surges of the utility model.
Fig. 2 is the schematic perspective view of the electric push-and-pull device that surges of the utility model.
In figure: 1-cylinder body, 2-oil pump, 3-motor, 4-piston, 5-piston rod, 6-hydraulic manifold block, 7-relief valve, 8-air valve, 9-observation panel, 10-seal ring, 11-joint, 12-guide sleeve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
A kind of electricity surges push-and-pull device, primarily of cylinder body 1, oil pump 2 and motor 3 form, described oil pump 2 is inputted by the driving of motor 3 or is extracted hydraulic oil in cylinder body 1, suitable piston 4 and piston rod 5 is provided with in described cylinder body 1, described oil pump 2 is provided with hydraulic manifold block 6, described hydraulic manifold block 6 is provided with relief valve 7, operationally, as piston rod 5 the over proof ouput force of external force of bearing or piston rod 5 reached range time, motor 3 is still in work, relief valve 7 meeting overflow rapidly and accurately, oil pressure is made to keep the pressure set up, thus protection motor 3 is not burnt, described oil pump 2 is provided with air valve 8 and observation panel 9, to observe in oil pump 2 whether bubble, the air that can enter in oil pump 2 is discharged, and ensures the stability of oil pressure in oil pump 2, described piston 4 is provided with seal ring 10, prevents leakage of oil from producing actual ouput force and theoretical ouput force produces error, described piston rod 5 end is provided with joint 11, and described cylinder body 1 end is provided with the guide sleeve 12 suitable with piston rod 5, ensures that piston rod 5 carries out push-and-pull campaign with rectilinear direction, makes push-pull effort according to ideal orientation effect.。
During the work of this device, in two kinds of situation, first is that piston rod 5 is extrapolated in cylinder body 1, started by motor 3, drive oil pump 2 to work, in fuel tank, inhalant liquid force feed flows through and input cylinder body 1 inside after hydraulic manifold block 6, hydraulic oil promotes piston 4 and outwards moves, and outwards provides thrust by piston rod 5; Second is need to pull working substance, and piston rod 5 is return in cylinder body 1, and its working principle is just contrary with the first situation above-mentioned with process.
This device realizes Automated condtrol, and the different thrust needed for working site or pulling force can according to circumstances carry out presetting, has overload self-protection function, is suitable for multi-field interiorly to use as power source.
Any employing and the similar push-and-pull device designed by technical characteristics of the utility model will fall within protection domain of the present utility model.
