Description

Hydraulic oil tank

Technical Field

The utility model relates to a hydraulic press technical field especially relates to a hydraulic tank.

Background

At present, when using the hydraulic press in the environment of rocking for a long time, because the vibration of machine during operation for the junction of outside oil return pipeline and hydraulic press oil tank takes place to drop easily, thereby influences hydraulic equipment's use. Therefore, it is necessary to provide a new hydraulic oil tank to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a hydraulic tank, it has solved the junction unstability of outside oil return pipe and hydraulic tank, the inconvenient technical problem of installation dismantlement.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a hydraulic oil tank, includes the box, returns the oil pipe, advances oil pipe and returns oil pipe clamping device, it includes a pair of connecting block, first spring, second spring, arm-tie and the clamp plate that sets up about returning oil pipe symmetry to return oil pipe clamping device, connecting block and box fixed connection, first spring both ends respectively with connecting block, arm-tie fixed connection, second spring both ends respectively with clamp plate, arm-tie fixed connection, the second spring is in compression state.

Further, the pressing plates are a pair of semicircular annular pressing plates.

Furthermore, an oil filling pipe is further arranged on the box body, and an oil filling cover is connected to the upper end of the oil filling pipe in a threaded mode.

Further, the side of the box body is also provided with a liquid level meter.

The utility model discloses during the use: by pulling the pull-plate upwards and pressing it downwards symmetrically about the return pipe

And the clamping device can be opened by the pulling plate, so that the connection of an external oil return pipeline and an oil return pipe of an oil tank of the hydraulic machine is facilitated. When the connection is completed, the pulling plate is loosened, and the semicircular annular pressing plate can clamp the oil return pipe under the action of the pulling force of the second spring because the second spring is in a compressed state.

The beneficial effects of the utility model are that:

1. through setting up clamping device for the outside returns oil pipe and hydraulic press oil tank and returns oil pipe junction more stable, is difficult for taking place to drop.

2. The clamping device can be opened by upwards lifting and pulling the pull plate and downwards pressing the pull plate symmetrically arranged relative to the oil return pipe, so that the connection of an external oil return pipeline and an oil return pipe of a hydraulic machine oil tank is facilitated.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

Referring to fig. 1 and 2, a hydraulic tank, including the box 1 of cuboid, return oil pipe 3, advance oil pipe 4 and return oil pipe clamping device 2, return oil pipe clamping device 2 and include a pair of connecting block 7, first spring 8, second spring 10, arm-tie 9 and the clamp plate 11 about returning oil pipe 3 symmetry setting, connecting block 7 and box 1 fixed connection, 8 both ends of first spring respectively with connecting block 7, arm-tie 9 fixed connection, 10 both ends of second spring respectively with clamp plate 11, arm-tie 9 fixed connection, second spring 10 is in compression state.

Further, in order to enable the pressure plate 11 to better press the pipeline, the pressure plate 11 is a pair of semicircular annular pressure plates 11 matched with the shape of the oil return pipe 3.

Furthermore, in order to conveniently add oil into the oil tank, the tank body 1 is further provided with an oil filling pipe 5, and the upper end of the oil filling pipe 5 is screwed with an oil filling cover 6.

Further, in order to detect the remaining amount of oil in the oil tank, a liquid level meter 12 may be disposed on a side surface of the tank body 1. The level gauge 12 can observe the level position of the hydraulic oil in the tank.

The utility model discloses during the use: when the upper pulling plate 9 is lifted upwards and the lower pulling plate 9 symmetrically arranged relative to the oil return pipe 3 is pressed downwards, the second spring 10 is changed from the original compression state to the stretching state, and due to the tensile force action of the second spring 10, the pressing plate 11 is far away from the oil return pipe 3, so that the clamping device 2 can be opened, and the connection of an external oil return pipeline and the oil return pipe 3 of the hydraulic machine oil tank is facilitated. When the connection is completed, the pulling plate 9 is released, and the second spring 10 is reset and is in a compressed state, so that the semicircular annular pressing plate 11 can clamp the oil return pipe 3 under the action of the pulling force of the second spring 10.

The beneficial effects of the utility model are that:

1. through setting up clamping device 2 for the junction is more stable with hydraulic press oil tank oil return pipe 3 to outside oil return pipeline.

2. The clamping device 2 can be opened by lifting the pulling plate 9 upwards and pressing the pulling plate 9 symmetrically arranged about the oil return pipe 3 downwards, so that the connection of an external oil return pipeline and the oil return pipe 3 of the hydraulic machine oil tank is facilitated.
