[0002] Most garbage compression stations are composed of functional components such as hydraulic devices and actuators. In actual operation, the hydraulic device provides power to control the operation of each actuator through various hydraulic valves. The hydraulic device of the existing garbage compression station is relatively large and uses a plug-in multi-way valve block, which has the following problems: 1. The failure rate is high, the installation and maintenance require high professionalism, and the operation is difficult due to space limitations; 2. The oil ports of each action are arranged up and down, and each group of actions has only one pressure oil port. However, in actual application, each actuator requires the cylinders on both sides to work at the same time, so an additional transition valve block is required for diversion to meet the use requirements (such as Figure 9 3. Many existing garbage compression stations are compact equipment, and the multi-way valve block + transition block format not only takes up a lot of space but also makes the hydraulic oil circuit layout complex, which easily leads to an increase in oil leakage points; 4.

DETAILED DESCRIPTION

[0035] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0036] In an embodiment of the present application, a new type of hydraulic valve block for a hydraulic device is provided. The hydraulic device includes a first hydraulic driving component 1, a second hydraulic driving component 2, and a hydraulic valve block 3 disposed between the first hydraulic driving component 1 and the second hydraulic driving component 2. Figures 1-4 As shown, the interior of the hydraulic valve block 3 is formed with an oil inlet main channel 402, a first oil inlet branch channel 401, a second oil inlet branch channel 403, an oil return main channel 502, a first oil return branch channel 501 and a second oil return branch channel 503. The oil inlet main channel 402 is used to input hydraulic oil to the first oil inlet branch channel 401 and the second oil inlet branch channel 403, and the oil return main channel 502 is used to output hydraulic oil from the first oil return branch channel 501 and the second oil return branch channel 503. The two ends of the first oil inlet branch channel 401 are used to respectively connect the oil inlet main channel 402 and the first oil inlet port of the first hydraulic drive component 1, and the two ends of the second oil inlet branch channel 403 are used to respectively connect the oil inlet main channel 402 and the second oil inlet port of the second hydraulic drive component 2. The two ends of the first oil return branch channel 501 are used to respectively connect the oil return main channel 502 and the first oil outlet port of the first hydraulic drive component 1, and the two ends of the second oil return branch channel 503 are used to respectively connect the oil return main channel 502 and the second oil outlet port of the second hydraulic drive component 2.

[0037] Specifically, the hydraulic device is suitable for a garbage compression station. The first hydraulic drive element 1 and the second hydraulic drive element 2 can both be hydraulic cylinders. The garbage compression station also includes a first actuator (such as a scraper mechanism or a lifting mechanism) and a second actuator (such as a slide mechanism or a hopper mechanism). The first actuator is connected to the first hydraulic drive element 1 and is located on the same side of the hydraulic valve block 3 as the first hydraulic drive element 1. The first actuator performs a corresponding function under the driving action of the first hydraulic drive element 1. The second actuator is connected to the second hydraulic drive element 2 and is located on the same side of the hydraulic valve block 3 as the second hydraulic drive element 2. The second actuator performs a corresponding function under the driving action of the second hydraulic drive element 2. This layout not only enhances the aesthetics of the hydraulic device but also facilitates commissioning and maintenance. The hydraulic device also includes a hydraulic oil tank 8 for storing hydraulic oil. The hydraulic oil tank 8 is formed with an oil outlet and an oil return end. The oil outlet is connected to the main oil inlet channel 402, and the oil return end is connected to the main oil return channel 502.

[0038] The first oil inlet is connected to the rodless chamber of the first hydraulic drive 1, and the first oil outlet is connected to the rod chamber of the first hydraulic drive 1. The second oil inlet is connected to the rodless chamber of the second hydraulic drive 2, and the second oil outlet is connected to the rod chamber of the second hydraulic drive 2. Furthermore, the hydraulic device further includes a first connecting line 11, a second connecting line 12, a third connecting line 13, and a fourth connecting line 14. The first connecting line 11 has two ends connected to the first oil inlet and the first oil inlet branch 401, respectively. The second connecting line 12 has two ends connected to the second oil inlet and the second oil inlet branch 403, respectively. The third connecting line 13 has two ends connected to the first oil outlet and the first oil return branch 501, respectively. The fourth connecting line 14 has two ends connected to the second oil outlet and the second oil return branch 503, respectively. The first connecting line 11 and the third connecting line 13 are located on the side of the hydraulic valve block 3 close to the first hydraulic drive 1, and the second connecting line 12 and the fourth connecting line 14 are located on the side of the hydraulic valve block 3 close to the second hydraulic drive 2.

[0039] The hydraulic oil in the hydraulic oil tank 8 enters the oil inlet main channel 402 through the oil outlet end, and then enters the first connecting line 11 and the second connecting line 12 from the first oil inlet branch channel 401 and the second oil inlet branch channel 403 respectively. The hydraulic oil entering the first connecting line 11 flows into the rodless cavity of the first hydraulic drive component 1, and the hydraulic oil entering the second connecting line 12 flows into the rodless cavity of the second hydraulic drive component 2. At the same time, the hydraulic oil in the rod cavity of the first hydraulic drive component 1 enters the first return oil branch channel 501 through the third connecting line 13, and the hydraulic oil in the rod cavity of the second hydraulic drive component 2 enters the second return oil branch channel 503 through the fourth connecting line 14. The hydraulic oil in the first return oil branch channel 501 and the second return oil branch channel 503 enter the return oil main channel 502 and then flow into the hydraulic oil tank 8 through the return oil end. The telescopic rods of the first hydraulic drive component 1 and the second hydraulic drive component 2 are extended, thereby realizing the hydraulic drive function of the first hydraulic drive component 1 and the second hydraulic drive component 2. If the flow direction of the hydraulic oil is opposite to the flow direction of the hydraulic oil when the telescopic rods of the first hydraulic driving component 1 and the second hydraulic driving component 2 are extended, the telescopic rods of the first hydraulic driving component 1 and the second hydraulic driving component 2 are retracted.

[0040] The hydraulic valve block 3 in this embodiment has a simple structure and a reasonable internal channel layout. Compared with the prior art, the hydraulic device using the hydraulic valve block 3 does not need to additionally set up a diverter valve block 15 (such as Figure 9 The transition is made by using the hydraulic pressure switch (as shown in the figure), which reduces pressure loss and hydraulic oil leakage points, helps to reduce the number of parts of the hydraulic device, and also improves the convenience of installation, commissioning and maintenance as well as the safety of use.

[0041] Furthermore, the main oil inlet channel 402, the first oil inlet branch channel 401, and the second oil inlet branch channel 403 together constitute the oil inlet channel 4, and the main oil return channel 502, the first oil return branch channel 501, and the second oil return branch channel 503 together constitute the oil return channel 5. The oil return channel 5 and the oil inlet channel 4 are spaced apart in the thickness direction of the hydraulic valve block 3. This arrangement can effectively avoid the intersection of the oil return channel 5 and the oil inlet channel 4 inside the hydraulic valve block 3, simplify the layout difficulty of the oil return channel 5 and the oil inlet channel 4 and the manufacturing difficulty of the hydraulic valve block 3, improve the rationality of the layout of the oil return channel 5 and the oil inlet channel 4, and make more full use of the internal space of the hydraulic valve block 3.

[0042] In one embodiment of the present application, the number of the first oil inlet branch channel 401 and the second oil inlet branch channel 403 are both multiple, and the multiple first oil inlet branch channels 401 are located on the same side of the oil inlet main channel 402 and are distributed in parallel and spaced along the length direction of the oil inlet main channel 402, and the multiple second oil inlet branch channels 403 are located on the same side of the oil inlet main channel 402 and are distributed in parallel and spaced along the length direction of the oil inlet main channel 402; the number of the first oil return branch channel 501 and the second oil return branch channel 503 are both multiple, and the multiple first oil return branch channels 501 are located on the same side of the oil return main channel 502 and are distributed in parallel and spaced along the length direction of the oil return main channel 502, and the multiple second oil return branch channels 503 are located on the oil return main channel 502 and are distributed in parallel and at intervals along the length direction of the oil return main channel 502. The above arrangement allows the staff to increase the number of actuators of the garbage compression station according to actual usage needs without having to design an additional hydraulic valve block 3 (the multiple actuators can be of the same type or different types). After the number of actuators is increased, the number of the first hydraulic drive component 1, the second hydraulic drive component 2, the first connecting pipeline 11, the second connecting pipeline 12, the third connecting pipeline 13 and the fourth connecting pipeline 14 is also adaptively increased, so that the hydraulic device in this embodiment can hydraulically drive more actuators, which is beneficial to further enhance the functionality, practicality and versatility of the garbage compression station.

[0043] Furthermore, when there are multiple first hydraulic drive components 1 (such as 4), the multiple first hydraulic drive components 1 are distributed on the same side of the hydraulic valve block 3, and the first oil inlet of each first hydraulic drive component 1 is connected to the multiple first oil inlet branches 401 in a one-to-one correspondence, and the first oil outlet of each first hydraulic drive component 1 is connected to the multiple first oil return branches 501 in a one-to-one correspondence; when there are multiple second hydraulic drive components 2 (such as 4), the multiple second hydraulic drive components 2 are distributed on the same side of the hydraulic valve block 3, and the second oil inlet of each second hydraulic drive component 2 is connected to the multiple second oil inlet branches 403 in a one-to-one correspondence; the second oil outlet of each second hydraulic drive component 2 is connected to the multiple second oil return branches 503 in a one-to-one correspondence.

[0044] In one embodiment of the present application, the setting direction of the main oil inlet channel 402 is consistent with the length direction of the hydraulic valve block 3, and the first oil inlet branch channel 401 and the second oil inlet branch channel 403 are symmetrically distributed along a direction perpendicular to the length direction of the main oil inlet channel 402;

[0045] The setting direction of the main oil return channel 502 is consistent with the length direction of the hydraulic valve block 3 , and the first oil return branch channel 501 and the second oil return branch channel 503 are symmetrically distributed along a direction perpendicular to the length direction of the main oil return channel 502 .

[0046] Specifically, the first oil inlet branch 401 and the second oil inlet branch 403 are connected as a whole along the width direction of the hydraulic valve block 3, and the first oil return branch 501 and the second oil return branch 503 are connected as a whole along the width direction of the hydraulic valve block 3. The above-mentioned channel layout can further reduce the manufacturing difficulty of the hydraulic valve block 3, simplify the regularity and aesthetics of the oil inlet channel 4 and the oil return channel 5, and facilitate the maintenance of the hydraulic valve block 3.

[0047] Another embodiment of the present application provides a hydraulic device for a garbage compression station, the hydraulic device comprising:

[0048] A first hydraulic drive member 1;

[0049] A second hydraulic drive member 2 is spaced apart from the first hydraulic drive member 1; and

[0050] The hydraulic valve block 3 in the above embodiment is used for a hydraulic device.

[0051] In one embodiment of the present application, the hydraulic device further includes a switch valve provided on the side wall of the hydraulic valve block 3, the switch valve being used to open or close the first oil inlet branch 401, wherein when the valve core of the switch valve is in a first preset position, the first oil inlet branch 401 is in a conducting state and the second oil inlet branch 403 is in a closed state (for example, Figure 5 In the state where the valve core of the switch valve is in the second preset position, the first oil inlet branch 401 is in the cut-off state and the second oil inlet branch 403 is in the conducting state (for example, Figure 5 In the state where the valve core of the switch valve is in the third preset position, the first oil inlet branch 401 and the second oil inlet branch 403 are both in the cut-off state ( Figure 5 The P port is not connected to the A port or the B port).

[0052] Specifically, the switch valve in this embodiment can be selected as a two-position three-way electromagnetic reversing valve 16, such as Figure 5As shown, the hydraulic oil enters from the P port, passes through the B side of the switch valve (or is called the left side to get power) and then enters the oil port B. The B port is connected to the hydraulic cylinder, and the hydraulic oil enters the large chamber of the hydraulic cylinder (i.e. the rodless chamber). At this time, the hydraulic cylinder extends, and the small chamber of the hydraulic cylinder (i.e. the rod chamber) is connected to the rod chamber connection port on the hydraulic valve block 3 (as shown in FIG. Figure 1 The rod cavity connection port of the hydraulic valve block 3 is connected to the oil outlet of the hydraulic valve block 3 (such as A1 port, A2 port, A3 port or A4 port) through the switch valve. Figure 1 The hydraulic oil flows back to the hydraulic tank 8 through the T' port in the middle. Alternatively, the hydraulic oil enters from the p port, passes through the hydraulic A side (or the right side is powered) and then enters the oil inlet A. The A port is connected to the hydraulic cylinder, and the hydraulic oil enters the small cavity of the hydraulic cylinder (i.e. the rod cavity). At this time, the hydraulic cylinder retracts, and the large cavity of the hydraulic cylinder (i.e. the rodless cavity) is connected to the rodless cavity connection port on the hydraulic valve block 3 (e.g. Figure 1 The rod cavity connection port of the hydraulic valve block 3 is connected to the oil outlet of the hydraulic valve block 3 (such as B1 port, B2 port, B3 port or B4 port) through the switch valve. Figure 1 The first oil inlet branch 401 or the second oil inlet branch 403 can be connected to the T' port in the middle of the oil inlet so that the hydraulic oil can flow back to the hydraulic oil tank 8. With the above arrangement, only one switch valve of this type can be used to control the conduction and cutoff of the first oil inlet branch 401 or the second oil inlet branch 403 according to actual needs, which is conducive to reducing the production cost of the hydraulic device.

[0053] In one embodiment of the present application, the hydraulic device also includes a first switch valve 6 and a second switch valve 7, both of which are arranged on the side wall of the hydraulic valve block 3. The first switch valve 6 is used to open or close the first oil inlet branch 401, and the second switch valve 7 is used to open or close the second oil inlet branch 403.

[0054] Specifically, if Figure 6-Figure 8 As shown, in this embodiment, the first on-off valve 6 and the second on-off valve 7 can be electromagnetic on-off valves. When the first on-off valve 6 is open, the first oil inlet branch 401 is connected, and the hydraulic oil in the main oil inlet channel 402 can enter the first hydraulic drive component 1 through the first oil inlet branch 401, allowing the first hydraulic drive component 1 to perform its hydraulic drive function. When the first on-off valve 6 is closed, the first oil inlet branch 401 is blocked, and the hydraulic oil in the main oil inlet channel 402 cannot enter the first hydraulic drive component 1 through the first oil inlet branch 401. In this case, the first hydraulic drive component 1 cannot perform its hydraulic drive function. Similarly, when the second on-off valve 7 is open, the second hydraulic drive component 2 can perform its hydraulic drive function; when the second on-off valve 7 is closed, the second hydraulic drive component 2 cannot perform its hydraulic drive function. With this design, a worker can control the opening or closing of the first on-off valve 6 and the second on-off valve 7 to control the simultaneous or independent execution of the hydraulic drive functions of the first and second hydraulic drive components 1 and 2, further improving the practicality of the hydraulic device.

[0055] Furthermore, when the number of the first oil inlet branches 401 and the second oil inlet branches 403 is multiple, the number of the first switch valves 6 and the number of the second switch valves 7 are also multiple, and the multiple first switch valves 6 are used to open or close the multiple first oil inlet branches 401 one by one, and the multiple second switch valves 7 are used to open or close the multiple second oil inlet branches 403 one by one.

[0056] In one embodiment of the present application, the first switch valve 6 and the second switch valve 7 are arranged on the same side wall of the hydraulic valve block 3 and are distributed along the width direction of the hydraulic valve block 3. If the number of the first switch valve 6 and / or the second switch valve 7 increases, the above-mentioned setting method can enable more first switch valves 6 and / or second switch valves 7 to be installed on the hydraulic valve block 3 at the same time, making the layout of the components of the hydraulic device more compact, which is conducive to reducing the overall occupied space of the hydraulic device, and further improving the integration of the hydraulic device and the convenience of installation and maintenance.

[0057] In one embodiment of the present application, the hydraulic device further includes a hydraulic oil tank 8 , the hydraulic valve block 3 is arranged on the hydraulic oil tank 8 , and the first switching valve 6 and the second switching valve 7 are both arranged on the vertical side wall of the hydraulic valve block 3 away from the hydraulic oil tank 8 .

[0058] Specifically, hydraulic oil is stored in the hydraulic oil tank 8, and the hydraulic valve block 3 is arranged on the vertical side wall of the hydraulic valve block 3 through a mounting bracket and is located in the middle position of the vertical side wall in the width direction. This arrangement further improves the overall aesthetics of the hydraulic device, facilitates the staff to connect or wire various connecting pipes or communication lines, and also facilitates the staff to install or repair components such as the hydraulic valve block 3, the first switch valve 6 and the second switch valve 7.

[0059] In one embodiment of the present application, the hydraulic oil tank 8 includes an oil outlet end and an oil return end, and the hydraulic device includes a first pipeline 9 and a second pipeline 10. The two ends of the first pipeline 9 are respectively connected to the oil outlet end and the main oil inlet channel 402, and the two ends of the second pipeline 10 are respectively connected to the oil return end and the main oil return channel 502. The first pipeline 9 and the second pipeline 10 are both metal parts.

[0060] Specifically, the hydraulic oil in the hydraulic oil tank 8 flows into the main oil inlet channel 402 of the oil inlet channel 4 through the first pipeline 9, and the hydraulic oil flowing out of the first hydraulic drive component 1 and the second hydraulic drive component 2 flows into the hydraulic oil tank 8 after passing through the return oil channel 5. The manufacturing material of the first pipeline 9 and the second pipeline 10 can be selected as steel. The first pipeline 9 and the second pipeline 10 made of this material are not only easy to connect and install, but also conducive to extending the overall service life of the hydraulic device.

[0061] In another embodiment of the present application, a garbage compression station is provided, such as Figure 10-11As shown, the garbage compression station includes the hydraulic device for the garbage compression station in the above embodiment. The hydraulic device is arranged at the center of the garbage compression station. The setting position is convenient for laying pipelines. When the first hydraulic drive component 1 and the second hydraulic drive component 2 on both sides of the hydraulic device move at the same time, the setting position can ensure that the pipelines from the setting position to the first hydraulic drive component 1 and the second hydraulic drive component 2 are symmetrically distributed, and the pipeline laying lengths are consistent, so as to avoid affecting the synchronization of the actions of the first hydraulic drive component 1 and the second hydraulic drive component 2.
