[0002] The cover and body of large equipment are generally connected by flanges and bolts. During the maintenance of the interior of the body after removing the cover, the following defects exist: the bolts and nuts are large in size, which makes disassembly time-consuming and labor-intensive, and there is also the risk of injury and damage to equipment if they fall; after the bolts and nuts are removed, it is difficult to separate the cover and the body from each other, and they need to be lifted with the help of lifting equipment. However, in the process of lifting the cover, as the pulling force increases, the cover and the body will be separated instantly, posing a safety hazard. Moreover, the installation space of the body is generally small, and the lifting of indoor equipment cannot be carried out due to space limitations, making equipment inspection and maintenance difficult and impossible to carry out.

[0003] To address the above defects, a hydraulic wrench is used to remove the bolts and nuts, and a hydraulic jack is used to separate the engine cover from the engine body. However, when using the hydraulic wrench and the hydraulic jack, they need to be connected to a hydraulic workstation. The hydraulic workstation is far away from the engine body, which makes it inconvenient to move, difficult to connect, and not easy to operate. Moreover, when in use, the oil pipeline on the hydraulic station may not be cleaned for a long time, and the oil on the inner wall may be mixed with dust and condensed, which may block the oil pipeline and make oil delivery difficult, causing the hydraulic wrench and the hydraulic jack to malfunction frequently, resulting in reduced maintenance efficiency of the engine body.

A refueling cap 6 is installed on the upper side of the oil tank 1 corresponding to the refueling port position. An oil pump 2 is installed on the upper side of the oil tank 1. The inlet of the oil pump 2 is fixedly connected to an oil suction pipe 7 with a lower end sealed and passing through the oil outlet. An oil inlet pipe 8 is fixedly connected between the outlet of the oil pump 2 and the inlet of the manual multi-way valve 4. An oil pressure regulator 9 is installed on the oil inlet pipe 8. A pressure gauge 10 is installed on the oil inlet pipe 8 between the oil pressure regulator 9 and the oil pump 2. The outlet of the manual multi-way valve 4 is fixedly connected to the return oil pipe 11 with the lower end sealed and passing through the return oil port. The first working inlet and the second working inlet of the manual multi-way valve 4 are fixedly connected to the first connecting pipe 12 and the second connecting pipe 13 respectively. The first working outlet and the second working outlet of the manual multi-way valve 4 are fixedly connected to the third connecting pipe 14 and the fourth connecting pipe 15 respectively. A reduction motor 3 is installed on the upper side of the oil tank 1, and the output shaft of the reduction motor 3 is transmission-connected to the center shaft of the oil pump 2.

[0018] According to the requirements, the oil filter 16 is an existing well-known 0.5Kw reduction motor, and a start switch and a stop switch for controlling the operation of the reduction motor 3 are provided on the upper side of the oil tank 1. The manual multi-way valve 4 is an existing well-known technology, such as the ZS-118 two-way reversing hydraulic valve, and the moving wheel 5 is an existing well-known technology, such as a universal caster with a brake. The first connecting pipe 12, the second connecting pipe 13, the third connecting pipe 14 and the fourth connecting pipe 15 are all existing well-known high-pressure hoses. During use, first add oil to the oil tank 1 through the refueling port according to the use requirements of the hydraulic equipment, and then connect the other ends of the first connecting pipe 12 and the third connecting pipe 14 to the outlet and inlet of the hydraulic equipment respectively. The hydraulic equipment is an existing well-known hydraulic wrench or hydraulic jack. Start the reduction motor 3, observe whether the pressure gauge 10 shows normal, and then adjust the oil pressure regulator 9 according to the working pressure of the hydraulic equipment, and then control the manual multi-way valve 4. The oil pump 2 pumps the oil in the oil tank 1 into the inlet of the hydraulic equipment, so that the hydraulic equipment starts working. After the work is completed, the reduction motor 3 stops working, and the oil in the hydraulic equipment flows back to the oil tank 1 through the outlet. The second connecting pipe 13 and the fourth connecting pipe 15 can be connected to other hydraulic equipment or to the oil filter equipment; when the first connecting pipe 12 and the third connecting pipe 14 fail, the hydraulic equipment can still work normally through the second connecting pipe 13 and the fourth connecting pipe 15.

[0019] The above-mentioned oil filtering and pressing dual-purpose movable pressure device can be further optimized and / or improved according to actual needs:

[0020] Example 2: As an optimization of the above example, as shown in the attached Figure 1As shown, an oil filter 16 is fixedly installed on the upper side of the oil tank 1, the second connecting pipe 13 is fixedly connected between the outlet of the oil filter 16 and the second working inlet of the manual multi-way valve 4, and the fourth connecting pipe 15 is fixedly connected between the second working outlet of the manual multi-way valve 4 and the inlet of the oil filter 16.

[0021] According to the requirements, the oil filter 16 is a plate-type oil filter known in the art. During use, hydraulic oil is added to the oil tank 1 from the filling port, the reduction motor 3 is started, and the reduction motor 3 drives the oil pump 2 to work. When the oil pump 2 is working, the hydraulic oil in the oil tank 1 is pumped into the inlet of the manual multi-way valve 4. The manual multi-way valve 4 is operated to allow the oil to enter the oil filter 16. The oil filter 16 filters out impurities in the oil, which can increase the recycling time of the oil and prevent impurities in the oil from damaging the hydraulic equipment. First, the first path in the manual multi-way valve 4 is opened. When the oil pump 2 is working, the oil in the oil tank 1 is pumped into the oil filter 16 for filtration. Then, the first path connected to the oil filter 16 is closed, and the second path in the manual multi-way valve 4 is opened. When the oil pump 2 is working, the oil in the oil tank 1 is pumped into the hydraulic equipment, so that the hydraulic equipment starts working.

[0022] Example 3: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, a connecting hole connecting the inside and the outside is provided on the left side of the lower part of the oil tank 1, and a liquid level gauge 17 is fixedly installed on the left side of the oil tank 1 corresponding to the position of the connecting hole. An oil drain hole connecting the inside and the outside is provided on the left side of the lower section of the oil tank 1 corresponding to the position below the connecting hole, and an oil drain pipe 18 is fixedly connected to the left side of the oil tank 1 corresponding to the position of the oil drain hole, and an oil drain valve 19 is installed on the oil drain pipe 18.

[0023] The level gauge 17 is a conventional tank level gauge. During operation, the level gauge 17 allows for oil to be added according to the hydraulic equipment's usage, preventing excessive oil waste or insufficient oil from affecting the normal operation of the hydraulic equipment. The drain pipe 18 and drain valve 19 facilitate the replacement of different types of oil and allow for the rapid collection of filtered and purified oil.

[0024] Example 4: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, a mesh-shaped mounting cylinder 20 is fixedly mounted on the inner side of the upper portion of the fuel tank 1 corresponding to the fuel filling port position, and a filter cylinder 21 is mounted in the mounting cylinder 20 .

[0025] As required, the filter cartridge 21 is a conventionally known hydraulic oil filter element, shaped like a cylinder with an open top and a closed bottom, mounted on the mounting cartridge 20. A plurality of through-holes are provided at intervals on the outside of the mounting cartridge 20, connecting the inside and the outside. This arrangement provides primary filtration of the oil flowing into the fuel tank 1 through the fuel filler port, preventing damage to the hydraulic equipment connected to the first and third connecting pipes 12, 14 during use.

[0026] Example 5: As an optimization of the above embodiment, as shown in the attached Figure 1 As shown, a plurality of internally and externally communicating oil return holes 22 are axially spaced apart on the outer side of the oil return pipe 11 corresponding to the inner side of the oil tank 1. During use, this arrangement prevents the return of high-pressure oil from impacting the oil in the oil tank 1, quickly reduces the oil pressure, and facilitates a rapid reduction in the oil temperature after operation, thereby increasing the number of cycles.

[0027] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
