[0033] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0034] Reference Figure 1 The present embodiment provides a hydraulic module with a protective cover, including a base 1, which is in the shape of a rectangular parallelepiped; a hydraulic assembly 2 is provided above the base 1, and the hydraulic assembly 2 includes a hydraulic pump, an oil inlet pipe, an oil outlet pipe, a connecting oil pipe and a reversing valve, and the hydraulic pump and the reversing valve are respectively fixed to the upper surface of the base 1 by bolts; the hydraulic pump and the reversing valve are connected and communicated by a plurality of connecting oil pipes, the upper end of the oil inlet pipe is connected and communicated with the hydraulic pump, and the lower end is placed in the inner cavity of the base 1, the upper end of the oil outlet pipe is connected and communicated with the reversing valve, and the lower end is placed in the inner cavity of the base 1; a through-hole is opened on the side wall of the base 1, and the oil inlet pipe and the oil outlet pipe can be drawn out from the through-hole and connected to the external oil tank and the output structure (such as a hydraulic telescopic arm) respectively.

[0035] Reference Figure 1 The outer periphery of the hydraulic assembly 2 is fastened to a cover 3. The cover 3 defines a receiving cavity 31. When the cover 3 is fastened, the hydraulic assembly 2 is placed within the receiving cavity 31. Hydraulic modules are often used on construction machinery in harsh environments. The cover 3 protects and dust-proofs the hydraulic assembly 2, thereby extending its service life.

[0036] Reference Figures 1 to 3 One end of the bottom of the base 1 is rotatably connected to the cover 3 through a hinge 11, and the other end is provided with a support frame 4; the hinge 11 is installed at the end position of the top of the base 1 and is provided with two symmetrical left and right parts, thereby being rotatably connected to the two inner walls of the cover 3 respectively.

[0037] Reference Figures 1 to 4 The upper sidewall of the support frame 4 is provided with a support portion 41, which is taller than the hydraulic assembly 2. The support portion 41 and the base 1 are located on the same side of the support frame 4. A first crimping portion 32 is provided at the end of the cover 3, which fits the support portion 41. The first crimping portion 32 is located at the end of the cover 3 that is away from the rotation center (i.e., the axis of hinge 11). When the cover 3 is fastened, the first crimping portion 32 presses against the support portion 41. When the cover 3 is fastened, the hinge 11 and the support portion 41 support the cover 3 from both ends, preventing the cover 3 from pressing against the hydraulic assembly 2, thereby protecting the hydraulic assembly 2.

[0038] Reference Figures 1 to 4 The cover 3 is provided with a convex abutment portion 33. When the cover 3 is in the flipped state, the abutment portion 33 abuts against the side wall of the base 1 directly or indirectly. Figure 4 When the height of the base 1 is not enough to directly abut the cover 3 with its side wall, the mounting legs 12 are fixed by bolts at the bottom end of the base 1 so that the abutting portion 33 abuts against the side wall of the legs 12. The bottom end of the mounting legs 12 is fixedly connected to the workbench by bolts.

[0039] Reference Figure 2 、 Figure 3 and Figure 5 The sidewall of the base 1 is provided with a support protrusion 13 (e.g., fixedly connected by bolts). The support protrusion 13 extends laterally to form a receiving surface at its top. The support protrusion 13 mates with the bottom edge of the cover 3. The support protrusion 13 is columnar. A buffer portion is provided at the top of the support protrusion 13, which is fixedly mounted on the receiving surface (e.g., fixedly connected or adhesively connected). The buffer portion is made of rubber material to achieve elastic pressure contact between the bottom of the cover 3 and the support protrusion 13, thereby preventing wear on the bottom of the cover 3.

[0040] Reference Figure 2The cover 3 includes a first plate 301 and a second plate 302 and a third plate 303 respectively arranged on the opposite long sides of the first plate 301. The first plate 301, the second plate 302 and the third plate 303 are fixedly connected in an integral manner or by bolts.

[0041] Reference Figure 2 The first crimping portion 32 and the abutting portion 33 are respectively provided at both ends of the first plate 301. The second plate 302 is an inverted right-angled trapezoidal plate structure, and the third plate 303 is an inverted right-angled trapezoidal plate structure. The second and third plates 302, 303 are arranged axially symmetrically. The first plate 301 is arranged along the long bottom sides of the second and third plates 302, 303 and extends to the ends of the long bottom sides, forming a convex structure on the upper portion of the rear end of the housing 3, namely the abutting portion 33.

[0042] Reference Figure 3 and Figure 5 Two support protrusions 13 are provided at the top of the long side walls of the base 1 to respectively fit the middle edge of the second plate 302 and the middle edge of the third plate 303. When the cover 3 is fastened, the middle of the lower edge of the second plate 302 and the middle of the lower edge of the third plate 303 are respectively pressed against the corresponding buffer portions of the two support protrusions 13.

[0043] Reference Figure 3 and Figure 6 The support frame 4 includes at least two columns 401, each of which is longitudinally arranged and of equal length. Adjacent columns 401 are fixedly connected by horizontal tie rods 402. A support plate 403 is provided on the upper sidewall of each column 401, with a support portion 41 disposed on the upper surface of the support plate 403. The ends of the tie rods 402 are vertically fixedly connected to the columns 401 (e.g., by bolts or welding). The support plate 403 is a 7-shaped plate structure. The support plate 403 is fixedly connected to the sidewalls of the columns 401 and / or the sidewalls of the tie rods 402 (e.g., by bolts or welding). The top surface of the support plate 403 has a locking hole 42, and a mounting nut is provided on the upper or lower surface of the support plate 403 (e.g., welded). The mounting nut is coaxial with the locking hole 42. The first plate 301 has a fixing hole that matches the locking hole 42, and a mounting bolt that matches the mounting nut is inserted into the fixing hole. After the cover 3 is buckled onto the outer periphery of the hydraulic assembly 2, the first crimping portion 32 is crimped onto the upper surface of the support plate 403, and the fixing hole, the locking hole 42 and the mounting bolt are in a coaxial state. At this time, the mounting bolt is passed through the fixing hole and screwed and fixed with the mounting nut to achieve locking of the cover 3. When the utility model is in working state, the cover 3 is prevented from accidentally opening and the cover 3 is prevented from bouncing due to bumps.

[0044] Reference Figure 6When the mounting nut is set on the upper surface of the top of the support plate 403, after the cover shell 3 is buckled on the support plate 403, a gap will be formed between the first crimping portion 32 and the support portion 41. The user can easily pry up the first crimping portion 32 (for example, using a flat-blade screwdriver) or grab and lift it (for example, using fingers) through the gap, thereby facilitating the opening of the cover shell 3.

[0045] Reference Figure 6 When the mounting nut is set at the lower surface position of the top of the support plate 403, after the cover shell 3 is buckled on the support plate 403, the first crimping portion 32 and the support portion 41 fit tightly without forming a gap, so the cover shell 3 has better sealing at the end close to the support frame 4, which can prevent dust in the use environment from entering the hydraulic pump through the gap. Therefore, when installing the utility model, the end where the support frame 4 is located needs to face the outside of the engineering vehicle to reduce the entry of dust; the external oil tank is installed flush with the support frame 4 on the vehicle floor to facilitate the replenishment of hydraulic oil through the oil filling hole.

[0046] Reference Figure 2 The cross section of the cover 3 is n-shaped.

[0047] Reference Figure 1 and Figure 6 , and also includes an electrical control cabinet 5, which is fixedly connected to the support frame 4, and the electrical control cabinet 5 is fixedly connected to the column 401 and / or the pull rod 402 by bolts, and the electrical control cabinet 5 and the cover 3 are arranged on opposite sides of the support frame 4 to avoid structural conflict; the electrical control cabinet 5 is connected to the external power supply.

[0048] Reference Figure 7 A winding terminal 404 is mounted on the support frame 4 and is attached to the back of the electrical control cabinet 5. The winding terminal 404 is equipped with a hook 4041 that can be adapted to attach to the pull rod 402. A ladder-shaped winding plate 4042 is integrally fixedly connected to the side of the hook 4041. The conductors and signal lines are wound and stored around the waist of the winding plate 4042 and locked with wire. This ensures that the remaining conductors and signal lines are as straight as possible to prevent them from being cluttered within the housing 31 of the housing 3 and becoming entangled with the connecting oil pipes, inlet pipes, and outlet pipes. The top side of the winding plate 4042, facing away from the pull rod 402, and both sides of the bottom are integrally fixedly connected to limiting protrusions 4043 to prevent the wound conductors and signal lines from slipping. One side of the winding plate 4042 is positioned within the threading gap 43.

[0049] The utility model has a simple structure and reliable functions. The cover shell 3 buckled on the outer periphery of the hydraulic component 2 protects and prevents the hydraulic component 2 from dust; the cover shell 3 is rotatably connected to the base 1 so as to be easy to flip open, and further facilitates the maintenance of the hydraulic component 2; the end of the base 1 away from the rotation center is provided with a support frame 4, and the support frame 4 is provided with a support part 41. When the cover shell 3 is buckled, the first crimping part 32 is crimped on the support part 41, and the hinge 11 and the support part 41 respectively support the cover shell 3 to prevent the cover shell 3 from crimping the hydraulic component 2; the electrical control cabinet 5 is fixedly connected to the support frame 4, and the support frame 4 is provided with a wire threading gap 43 for wiring, thereby facilitating the layout of wires and signal lines.
