[0030] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0031] Reference Figure 1 This embodiment provides a hydraulic drive module for an engineering vehicle bed, comprising a housing 1 and a hydraulic assembly 2 disposed within the interior of the housing 1. The housing 1 provides a housing for the hydraulic assembly 2, protects the hydraulic assembly 2 from collision damage, and enables modular installation of the hydraulic assembly 2. During production and assembly, the hydraulic assembly 2 and the housing 1 are pre-assembled in advance, and the entire device is then bolted to the supporting frame of the engineering vehicle, thereby adapting to the frame's assembly efficiency and achieving flexible assembly.

[0032] Reference Figure 1The housing 1 includes a box body 11 and a cover body 12 rotatably connected to the box body 11. A damping telescopic rod 13 is installed at the center of the bottom surface of the cover body 12. When the cover body 12 is buckled onto the top of the box body 11, the inner cavity of the box body 11 forms a closed space for accommodating and protecting the hydraulic assembly 2.

[0033] Reference Figure 1 The hydraulic assembly 2 includes an oil tank 21, a hydraulic pump 22, an electromagnetic reversing valve 23, a wired remote control 24, a wireless remote control, a wireless signal receiver 25 and a controller; the oil tank 21 is fixedly connected and communicated with the hydraulic pump 22, and the hydraulic pump 22 is installed at the oil outlet of the oil tank 21. The oil outlet is set at the bottom of the side wall of the oil tank 21 to ensure that no air enters the hydraulic pump 22 when the liquid level in the oil tank 21 changes. The hydraulic pump 22 is connected and communicated with the electromagnetic reversing valve 23 through an oil pipe, and the electromagnetic reversing valve 23 is provided with an interface adapted to the oil outlet pipe. During assembly, one end of the oil outlet pipe is connected and communicated with the electromagnetic reversing valve 23, and the other end is connected and communicated with the hydraulic mechanical telescopic arm of the engineering vehicle. The hydraulic pump 22 is used to press the hydraulic oil in the oil tank 21 into the hydraulic mechanical telescopic arm, and the hydraulic telescopic arm drives the movement of the wing panels on the side of the wingspan vehicle. A piston is provided in the oil pressure chamber of the hydraulic telescopic arm. The front and rear ends of the oil pressure chamber are connected to the electromagnetic reversing valve 23 through the oil outlet pipe respectively. The electromagnetic reversing valve 23 is used to control the hydraulic oil to selectively flow into the front or rear end of the oil pressure chamber to push the piston to move in the opposite direction, thereby realizing the extension or shortening of the hydraulic telescopic arm to drive the opening or closing of the wing plate.

[0034] The hydraulic pump 22, solenoid reversing valve 23, wired remote control 24, and wireless signal receiver 25 are each connected to the controller via wires and / or signal lines. The controller is also connected to the power lock 114 via wires, which in turn is connected to an external power supply via wires; the external power supply is the engineering vehicle's electrical system. While the engineering vehicle is in motion, the operator uses a key to disable the power lock 114, de-energizing the hydraulic assembly 2 to prevent accidental activation and ensure driving safety.

[0035] Reference Figure 2 and Figure 3 The power lock 114 is installed on the side wall of the box body 11 through the power lock 114, and is fixedly connected to the side wall of the box body 11 by bolts.

[0036] Reference Figure 1 and Figure 2 One side edge of the cover 12 is connected to one side edge of the top surface of the box body 11 through a hinge, so as to achieve mutual rotation.

[0037] Reference Figure 1 and Figure 2The cross-section of the box body 11 is an isosceles trapezoid, adapted to the installation space on the frame of an engineering vehicle. The top surface of the box body 11 is provided with an opening 111, the inner sidewall of which extends inward to form an annular inner extension 112 (e.g., via an integrated fixed connection). A first connecting piece 113 (e.g., fixedly connected by bolts) is provided in the middle of the inner sidewall of the inner extension 112 near the hinge. A second connecting piece 121 (e.g., fixedly connected by bolts) is provided on the lower surface of the cover body 12. The first connecting piece 113 and the second connecting piece 121 are rotatably connected to the ends of the damping telescopic rod 13, respectively. After the user opens or closes the cover body 12, the damping telescopic rod 13 can keep the cover body 12 in the open or closed state, thereby preventing the cover body 12 from accidentally popping open due to bumps during driving of the engineering vehicle or accidentally closing the cover body 12 during maintenance.

[0038] Reference Figure 1 and Figure 2 The hinge is arranged at the top of the side wall of the box body 11 corresponding to the long bottom side of the isosceles trapezoid, so that the box body 11 and the cover body 12 have as long a contact line as possible, thereby facilitating the installation of more or longer hinges.

[0039] Reference Figure 3 and Figure 4 A cross-shaped limiting protrusion 115 is provided at the center of the bottom plate of the inner cavity of the box body 11 (for example, fixedly connected by bolts), and the limiting protrusion 115 is provided with at least four card slots in the concave position, and the four card slots are respectively a first card slot 1151, a second card slot 1152, a third card slot 1153 and a fourth card slot 1154.

[0040] Reference Figure 3 and Figure 4 The fuel tank 21 is positioned at any inner corner of the inner cavity of the housing 11 near the rotation center of the cover 12. The sidewall of the fuel tank 21 away from the hydraulic pump 22 fits snugly within this inner corner. The sharp corner of the sidewall of the fuel tank 21 near the hydraulic pump 22 is positioned within the first retaining groove 1151. This inner corner and the first retaining groove 1151 respectively clamp the fuel tank 21 from diagonally opposite sides to prevent the fuel tank 21 from shaking and striking the electromagnetic reversing valve 23, wireless signal receiver 25, and controller during driving of the engineering vehicle, thereby protecting the electromagnetic reversing valve 23, wireless signal receiver 25, and controller from damage.

[0041] Reference Figure 3 and Figure 4The electromagnetic reversing valve 23 is fixedly mounted in the second slot 1152, and its housing is fixedly connected to the limiting protrusion 115 via bolts. The wireless signal receiver 25 and the controller are both fixedly mounted in the fourth slot 1154, and its housing is fixedly connected to the limiting protrusion 115 via bolts. The housing of the wireless signal receiver 25 is also fixedly connected to the limiting protrusion 115 via bolts. The housing of the controller is also fixedly connected to the limiting protrusion 115 via bolts. The wireless signal receiver 25 is stacked above the controller.

[0042] Reference Figures 3 to 5 The wired remote control 24 can be removably inserted into the third slot 1153. The housing of the wired remote control 24 is provided with a receiving groove. The sidewalls of the third slot 1153 are integrally fixedly connected with receiving ribs, which are vertically positioned and fit into the receiving groove. While the construction vehicle is in motion, the user inserts the wired remote control 24 into the third slot 1153 to prevent the wired remote control 24 from shaking and potentially striking the fuel tank 21, the solenoid reversing valve 23, the wireless signal receiver 25, and the controller.

[0043] Reference Figure 3 and Figure 4 The limiting protrusion 115 is provided with a wiring hole 11501, the second slot 1152 and the fourth slot 1154 are connected through the wiring hole 11501, and the wires and signal lines used to connect the electromagnetic reversing valve 23 and the controller can pass through the wiring hole 11501; the wires and signal lines used to connect the hydraulic pump 22 and the controller can pass through the wiring hole 11501, thereby facilitating wiring.

[0044] Reference Figure 5 The wires and signal lines connected to the wired remote controller 24 bypass the limiting protrusion 115 and are connected to the controller.

[0045] Reference Figure 6 A wiring groove is provided on the top of the side wall of the box body 11. After the user opens the cover body 12, the wired remote control 24 is pulled out from the inner cavity of the box body 11, and the wires and signal lines connected to the wired remote control 24 are placed in the wiring groove, and then the cover body 12 is buckled; thereafter, the user uses the wired remote control 24 to control the hydraulic assembly 2 to drive the hydraulic telescopic arm to operate and open or close the wing plate to prevent dust from entering the inner cavity of the box body 11 during operation and causing damage to the hydraulic pump 22 and the controller.

[0046] When the hydraulic assembly 2 needs to be remotely controlled, the user controls the controller via the wireless signal receiver 25 via the wireless remote controller, and further controls the operation of the electromagnetic reversing valve 23 and the hydraulic pump 22. The wireless remote controller is placed in the inner cavity of the box 11 or in the cab to achieve accompanying travel.

[0047] The controller is a PLC controller.

[0048] The utility model utilizes the shell 1 as the supporting structure of the hydraulic component 2, integrates the main driving structure of the hydraulic system into the inner cavity of the box body 11, realizes the integration of the hydraulic drive module, realizes the batch and standardized connection of the hydraulic component 2, and improves the installation accuracy; the box body 11 is adapted to the frame of the engineering vehicle for installation, avoiding the connection of each structure in the hydraulic component 2 to the frame one by one, thereby making the installation more convenient and accurate; the shell 1 has a protective function for the hydraulic component 2 while realizing module integration, protecting the hydraulic component 2 from external impact; the limiting protrusion 115 is used to avoid mutual collision of the various structures in the hydraulic component 2; the user can control the start and stop and other working states of the hydraulic pump 22 and the electromagnetic reversing valve 23 through the wired remote control 24 or the wireless remote control, and further control the opening and closing of the wing panels on the wingspan vehicle, which is convenient to use, stable and reliable.
