Abstract
A device for mounting and demounting a piston of a servomotor comprises a frame, a puller and a hydraulic pump, the frame is of a lifting structure, the puller and the hydraulic pump are mounted on the frame, the hydraulic pump is connected with the puller through a pipeline which is provided with a pressure gauge, rollers are arranged at the bottom of the frame, and the hydraulic pump is provided with an auxiliary oil tank. The piston can be gripped, plugged, unplugged, lifted, moved and the like by the device for mounting and demounting the piston of the servomotor by the aid of the mechanical rotation principle and the hydraulic principle, so that mechanization of the operations can be achieved. The device for mounting and demounting the piston of the servomotor is simple to assemble, convenient to operate and capable of quickly and effectively demounting and mounting the piston of the servomotor during use.
Description
Technical field
The utility model relates to a kind of device that the servomotor piston removes and installs that is used for, and is applicable to the dismounting and the installation of Hydraulic Power Unit governing system servomotor piston.
Background technology
The power station servomotor generally will carry out the dismounting and the installation procedure of servomotor piston when overhauling, the about 370Kg-400Kg of a kind of servomotor piston weight adopted artificial method to dismantle and installed in the past.Need keep higher smoothness during operation, need minor impact sometimes, just can pull down and be in place, effort, time-consuming, and be prone to cause pull bar and piston combining part bit loss wound and personnel to injure incident by a crashing object.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of device that the servomotor piston removes and installs that is used for, and application machine rotary principle and hydraulic principle are realized grabbing of piston taken, plug, up-down, moved etc., to realize the mechanization of this operation.Assembling is simple, easy to operate in this device use, can be fast effectively dismantle, installation servomotor piston.
The above-mentioned purpose of the utility model is to realize through such technical scheme: a kind ofly be used for the device that the servomotor piston removes and installs; Comprise vehicle frame, draw horse, hydraulic pump; Said vehicle frame is a lifting structure, and said horse, the hydraulic pump of drawing is installed on the vehicle frame, and hydraulic pump draws horse through the pipeline connection.
Said bottom of frame is provided with roller.
Said hydraulic pump is provided with service tank.
Said pipeline is provided with Pressure gauge.
The utility model is a kind of to be used for the device that the servomotor piston removes and installs, and the oil pressure pipeline is provided with Pressure gauge, is convenient to monitor hydraulic pump pressure, and the regulator solution press pump is under desirable working condition.Hydraulic pump is provided with service tank, can adapt to large-tonnage, big stroke operation needs.Bottom of frame is provided with roller, and device integral body is convenient to move.
The utility model device will draw horse to be fixed to institute and draw on the workpiece, and the handle on the operation hydraulic pump can reach and unload lower piston and the purpose that piston is installed.This device can move up and down dismounting servomotor piston, also can be used for the dismounting operation of other workpiece, like heavy duty oil cylinder end cap, blind flange, belt pulley, bearing etc., can push away at any time and walk, and uses laborsaving.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the utility model apparatus structure sketch map.
The specific embodiment
As shown in Figure 1, a kind ofly be used for the device that the servomotor piston removes and installs, comprise vehicle frame 1, draw horse 2, hydraulic pump 3 that said vehicle frame 1 is a lifting structure, said horse 2, the hydraulic pump 3 of drawing is installed on the vehicle frame 1, and hydraulic pump 3 connects through pipeline 4 and draws horse 2.Vehicle frame 1 bottom is provided with roller 5.Hydraulic pump 3 is provided with service tank.Pipeline 4 is provided with Pressure gauge.
Embodiment:
The utility model device comprises vehicle frame 1, draws horse 2, hydraulic pump 3, and hydraulic pump 3 is provided with operating grip.Vehicle frame 1 is a lifting structure, and the top is provided with descending operation handle 6.The utility model device is according to the weight of piston, as: the ability to work of the weight capacity of 400Kg design vehicle frame 1 and the handgrip of La Ma 2.Mechanical handgrip when drawing horse 2 to be the workpiece dismounting need be fixed on during use by on the workpiece of dismounting.Under the situation of using supporting oil cylinder and specific purpose tool, can carry out various operations, for example: lifting, bending, alignment, shearing, riveted, assembling, dismounting construction etc., realized the mechanization of this operation.Vehicle frame 1 bottom is provided with roller 5, and complete machine can be walked freely, and the ability oscilaltion is easy to operate, safe in utilization, loads and unloads advantages such as quick.
During first the use, hydraulic pump 3 adds kinematic viscosity and is machinery oil or the hydraulic oil of 20-28 cst, and is lubricated to improve.When oil pump was worked at pressure 70MPa, the performance of oil pump was brought into play safely, is the most reasonably to use, and did not all need adjustment everywhere.When actual working pressure is lower than 70MPa, do not need adjustment everywhere yet.Can enlarge the scope of application of oil pump, for adapting to supporting oil cylinder, can be lower than work under the pressure of 70MPa, be connected on Pressure gauge pipeline 4 on earlier this moment, regulates high pressure valve, reaches when Pressure gauge till the operating pressure of oil cylinder, can use.In order to adapt to the needs of large-tonnage, big stroke operation, but otherwise designed is made large-scale fuel tank or service tank.
The technical parameter of the utility model: drawing ability 100T, dismounting scope 550-750mm, impulse stroke 200mm, operating pressure 70MPa; High-pressure 70MPa, low pressure 1MPa, high pressure flow 2.3ML/ time; Low pressure flow 12.52.3ML/ time, maximum hand power 500N, oil reserve 5L.
