Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic devices, in particular to a miniaturized automatic hydraulic device. Background Art

[0002] Most of the existing hydraulic support devices are of split design, that is, the hydraulic support part (hydraulic jack), oil tank and hydraulic pump are assembled separately, and the hydraulic pump is connected to the oil tank and the hydraulic support part through an oil pipe to provide hydraulic power to the hydraulic support part, which increases the difficulty of on-site assembly. For example, during the assembly process, if the oil pipe is damaged, the hydraulic pressure of the hydraulic support part will be insufficient, and the hydraulic support part cannot be moved into place, and normal use cannot be guaranteed. In addition, the split method will also cause the hydraulic support device itself to be larger in size, which is extremely inconvenient to disassemble and carry.

[0003] In view of the above, it is necessary to provide a new type of miniaturized automatic hydraulic device to overcome the above defects. Utility Model Content

[0004] The purpose of the utility model is to provide a miniaturized automatic hydraulic device, which directly assembles the oil tank, the hydraulic support part and the hydraulic pump together, and no longer needs to be connected with the oil production pipe, so as to avoid the inability to use normally due to the damage of the oil pipe. At the same time, the overall volume of the device is also reduced, which is convenient for disassembly, handling and transportation.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a miniaturized automatic hydraulic device, including: a hydraulic support mechanism, an oil tank, a valve block assembly, a hydraulic pump, a control module and a shockproof plate;

[0010] Preferably, a sealing gasket is also provided below the mounting plate.

[0011] Preferably, the miniaturized automatic hydraulic device further comprises a protective cover, which is mounted on the valve block assembly and wraps the hydraulic pump, the pressure gauge and the pressure sensor.

[0028] See also Figures 1 to 3 The utility model provides a miniaturized automatic hydraulic device, comprising: a hydraulic support mechanism 1, an oil tank 5, a valve block assembly 3, a hydraulic pump 8, a control module 7 and a shockproof plate 10;

[0029] The hydraulic support mechanism 1 is provided with a displacement sensor, the control module 7 has an alarm and a fault indicator light, the valve block assembly 3 is provided with a pressure gauge 31 and a pressure sensor 32, and the pressure sensor 32, the displacement sensor and the alarm are all electrically connected to the control module 7.

[0030] The oil tank 5 is fixedly installed on one side of the hydraulic support mechanism 1, and the oil tank 5 is connected to the hydraulic support mechanism 1, the valve block assembly 3 is fixedly installed on the oil tank 5, the hydraulic pump 8 is fixedly installed on the valve block assembly 3 and extends into the oil tank 5 through the valve block assembly 3, the control module 7 is fixedly installed on the oil tank 5 and is electrically connected to the hydraulic pump 8, the displacement sensor and the alarm are electrically connected to the control module, the hydraulic support mechanism 1 and the oil tank 5 are both fixedly installed on the shockproof plate 10, the control module 7 is used to control the start and stop of the hydraulic support mechanism 1, and the displacement sensor is used to detect the movement distance of the hydraulic support mechanism 1.

[0031] It should be noted that, in this embodiment, the hydraulic support mechanism 1 is a hydraulic jack, and the control module 7 can be a PLC controller.

[0032] When the control module 7 controls the hydraulic pump 8 to start, the hydraulic pump 8 pumps the hydraulic oil in the oil tank 5 into the hydraulic support mechanism 1, so that the hydraulic support mechanism 1 rises and plays a lifting role. The displacement sensor detects whether the rising movement distance of the hydraulic support mechanism 1 is in place, and uploads the detected movement distance information to the control module 7. On the contrary, when the control module 7 controls the hydraulic pump 8 to stop working, the hydraulic support mechanism 1 descends and returns to its original state.

[0033] The pressure sensor 32 is used to detect the pressure of the hydraulic oil in the hydraulic support mechanism 1, and upload the detected pressure information to the control module 7. The pressure information is displayed on the pressure gauge 31. When the pressure of the hydraulic support mechanism 1 does not match the preset value, the control module 7 will automatically adjust the output of the hydraulic pump 8, so that the pressure of the hydraulic support mechanism 1 reaches the preset value. By centrally arranging the pressure gauge 31, the pressure sensor 32 and the hydraulic pump 8 on the valve block assembly 3, and the hydraulic support mechanism 1 and the oil tank 5 are fixedly installed on the shockproof plate 10, this installation method reduces the overall volume, thereby reducing the occupied space.

[0034] In a preferred embodiment, the hydraulic support mechanism 1 has an oil inlet nozzle, the oil tank 5 has an oil outlet nozzle, and the hydraulic support mechanism 1 is connected to the oil outlet nozzle of the oil tank 5 through the oil inlet nozzle.

[0035] In a preferred embodiment, the oil tank 5 further has an oil filling nozzle 51 . When the hydraulic oil in the oil tank 5 is insufficient, hydraulic oil can be injected into the oil tank 5 through the oil filling nozzle 51 .

[0036] In a preferred embodiment, the miniaturized automatic hydraulic device further includes a connecting plate 2, the hydraulic support mechanism 1 is cylindrical, and a rectangular mounting groove 11 is provided on the outer wall of the hydraulic support mechanism 1, the connecting plate 2 is fixedly installed at the mounting groove 11, and the oil tank 5 is fixedly installed with the connecting plate 2. In this way, the oil tank 5 can be fixedly installed on one side of the hydraulic support mechanism 1.

[0037] In a preferred embodiment, the miniaturized automatic hydraulic device further comprises a buffer pad 101, the buffer pad 101 is fixedly installed in the installation groove 11, and the connecting plate 2 is connected between the buffer pad 101 and the oil tank 5. By providing the buffer pad 101, the vibration of the hydraulic support mechanism 1 during movement can be reduced.

The miniaturized automatic hydraulic device also includes a handle 9, which is movably mounted on the two bayonet pins 21 to facilitate lifting the miniaturized automatic hydraulic device through the handle 9.

[0039] Specifically, the handle 9 is U-shaped and has a strip hole 91 at each end. The strip hole 91 corresponds to a bayonet 21 for movable installation. The bayonet 21 matches the size of the strip hole 91, and the bayonet 21 can slide in the corresponding strip hole 91. Pull up the handle 9 to lift the miniaturized automatic hydraulic device; when the miniaturized automatic hydraulic device needs to be stored, press down the handle 9.

[0040] Furthermore, each bayonet 21 is formed with an anti-slip head 211 , the diameter of which is larger than the diameter of the portion of the bayonet 21 other than the anti-slip head 211 , thereby preventing the strip hole 91 of the pull head from falling off the bayonet 21 .

[0041] In a preferred embodiment, the miniaturized automatic hydraulic device also includes a mounting plate 4, which is mounted on the opening of the oil tank 5, the valve block assembly 3 is fixedly mounted on the mounting plate 4, and the hydraulic pump 8 and the pressure sensor 32 extend through the mounting plate 4 into the oil tank 5.

[0042] In a preferred embodiment, a sealing gasket 41 is further provided under the mounting plate 4. The shape of the sealing gasket 41 corresponds to the shape of the mounting plate 4. When the mounting plate 4 is installed at the opening of the oil tank 5, the sealing gasket 41 is in close contact with the opening of the oil tank 5 to enhance the sealing performance and prevent oil leakage.

[0043] In a preferred embodiment, the miniaturized automatic hydraulic device further comprises a protective cover 6, which is fixedly mounted on the valve block assembly 3 and wraps the hydraulic pump 8, the pressure gauge 31, and the pressure sensor 32, thereby playing a protective role.

[0044] In a preferred embodiment, the protective cover 6 is provided with an observation port 61 in a region corresponding to the pressure gauge 31 , so that the pressure data of the pressure gauge 31 can be directly observed through the observation port 61 .

[0045] When in use, the control module 7 controls the hydraulic pump 8 to start, and the hydraulic pump 8 pumps the hydraulic oil in the oil tank 5 into the hydraulic support mechanism 1, so that the hydraulic support mechanism 1 rises and plays a jacking role. Conversely, when the control module 7 controls the hydraulic pump 8 to stop working, the hydraulic support mechanism 1 descends and returns to its original state. During this process, the pressure information can be observed through the pressure gauge to determine the load-bearing capacity of the hydraulic support mechanism 1.
