This system consists of several key hydraulic components, including a multi-way valve, a parking valve, a hydraulic pump, and a hydraulic tank. However, in existing technologies, the hydraulic components of forklifts are relatively dispersed, resulting in a larger installation space requirement, increased demand for mounting hardware, and consequently, increased maintenance difficulty. Utility Model Content

[0005] In a preferred embodiment, the plurality of hydraulic components are respectively horizontally mounted on the mounting bracket.

[0006] In a preferred embodiment, the mounting bracket is elongated, and the plurality of hydraulic components are distributed along the length of the mounting bracket.

[0007] In a preferred embodiment, the mounting bracket has mounting holes at both ends along its length, the mounting holes being used to install and fix the mounting bracket with screws or bolts; the mounting holes are oblong holes, and the oblong hole at one end of the mounting bracket extends along the length of the mounting bracket, while the oblong hole at the other end of the mounting bracket extends along the width of the mounting bracket.

[0008] In a preferred embodiment, the plurality of hydraulic components further includes a lifting block, the multi-way valve is located between the lifting block and the filling parking valve, and a second hydraulic line is connected between the multi-way valve and the lifting block.

[0009] In a preferred embodiment, the mounting bracket is used to mount the multi-way valve with the mounting surface lower than the mounting surfaces of the lifting block and the filling parking valve, so as to provide clearance space above the multi-way valve for the forklift's hydraulic pump.

[0010] In a preferred embodiment, the mounting bracket is a plate-like structure in the shape of an inverted "V". The multi-way valve is installed in the middle of the mounting bracket, and the lifting oil block and the filling parking valve are respectively installed on both sides of the mounting bracket.

[0025] In this utility model, the terms "first," "second," and "third," etc., are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "left," "right," "front," "back," "top," and "bottom" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and is only for the convenience of describing this utility model, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Furthermore, in the description of this utility model, unless otherwise stated, "multiple" refers to two or more.

[0026] Please see Figures 1-4 As shown, this utility model discloses a compact hydraulic device, comprising an integral mounting bracket 1 and multiple hydraulic components. The multiple hydraulic components are mounted on the mounting bracket 1, and include a multi-way valve 2 and a filling parking valve 3. A first hydraulic pipeline 5 connects the multi-way valve 2 and the filling parking valve 3. The integral mounting bracket 1 means that the mounting bracket 1 is a one-piece molded structure, or that the mounting bracket 1 is composed of multiple parts connected into a single structure.

[0027] Each hydraulic component is horizontally mounted on the mounting bracket 1, which greatly reduces the risk of hydraulic components falling off and improves safety during assembly. In particular, the horizontal mounting method of the multi-way valve 2 can greatly simplify the installation steps of the multi-way valve 2 and reduce the use of lifting tools and manpower.

[0028] Mounting bracket 1 is elongated, with multiple hydraulic components distributed along its length. This design makes the layout of the hydraulic components more intuitive, facilitating installation and maintenance, optimizing space utilization, and preventing interference between hydraulic components within a limited space.

[0029] The mounting bracket 1 has multiple mounting holes 11 at both ends along its length. These mounting holes 11 are used to engage screws or bolts to secure the mounting bracket 1. Preferably, the mounting holes 11 are oblong, with one end extending along the length of the mounting bracket 1 and the other end extending along its width. Therefore, when fixing the mounting bracket 1, its position can be fine-tuned in both the length and width directions, improving adaptability and reducing the precision requirements for installation, thus lowering installation difficulty and time costs.

[0030] The aforementioned hydraulic components also include a lifting block 4, a multi-way valve 2 located between the lifting block 4 and the filling parking valve 3, and second hydraulic lines 6 connected between the multi-way valve 2 and the lifting block 4, and between the multi-way valve 2 and the filling parking valve 3, respectively. The mounting bracket 1 is used to mount the multi-way valve 2 with its mounting surface lower than the mounting surfaces of the lifting block 4 and the filling parking valve 3, so as to provide clearance for the forklift's hydraulic pump above the multi-way valve 2. The mounting bracket 1 has multiple connection holes 12 corresponding to each hydraulic component, and each hydraulic component is connected to the corresponding connection hole 12 using screws or bolts.

[0031] Mounting bracket 1 is a roughly inverted V-shaped plate structure. The multi-way valve 2 is installed in the middle of mounting bracket 1, while the lifting hydraulic block 4 and the filling parking valve 3 are installed on either side of mounting bracket 1. The top surface of mounting bracket 1 forms the mounting surface for all hydraulic components. Reinforcing plates 13 are provided between the bottom surfaces of both sides of mounting bracket 1 and the bottom surface of the middle section of mounting bracket 1. This is because the multi-way valve 2 is relatively heavy and bulky; by providing reinforcing plates 13, the strength of the middle section of mounting bracket 1 can be improved. A fixing plate 14 is provided on the middle side of mounting bracket 1. A hydraulic oil filter (not shown in the figure) is installed on this fixing plate 14, and a hydraulic pipeline connects the hydraulic oil filter to the multi-way valve 2. Specifically, the upper end of the fixing plate 14 is fixed to one side of the middle section of mounting bracket 1 in the width direction, and the lower end of the fixing plate 14 extends downwards, with the fixing plate 14 parallel to the length direction of mounting bracket 1.

[0032] During installation, first horizontally install the multi-way valve 2, the liquid-filling parking valve 3, and the lifting hydraulic block 4 in their respective positions on the mounting bracket 1, and then install the pipe fittings. Figure 2 As shown; next, the first hydraulic line 5 connecting the multi-way valve 2 and the filling parking valve 3, the second hydraulic line 6 connecting the multi-way valve 2 and the lifting block 4, the third hydraulic line 7 that the multi-way valve 2 needs to connect to external systems, the fourth hydraulic line 8 that the filling parking valve 3 needs to connect to external systems, and the fifth hydraulic line 9 that the lifting block 4 needs to connect to external systems, as shown. Figure 3 As shown; then move the entire hydraulic unit to the front of the forklift frame, install the mounting bracket 1 at the designated position on the front of the forklift frame 10, and extend the mounting bracket 1 along the left and right direction of the frame 10, as shown. Figure 4 As shown.

[0033] This utility model mounts multiple hydraulic components on the same mounting bracket 1, which reduces the use of separate brackets, thereby reducing the space occupied, making the layout of multiple hydraulic components more compact, reducing the use of mounting fasteners and materials, simplifying the installation process, and saving costs.

[0034] This utility model discloses a forklift, including a frame 10 and a compact hydraulic device as described above. A mounting bracket 1 is installed on the frame 10. Specifically, the mounting bracket 1 is installed on the front side of the frame 10 and extends along the left-right direction of the frame 10. This achieves a compact overall layout while facilitating the inspection and maintenance of each hydraulic component.
