Description

Technical Field

[0001] This utility model relates to the field of hydraulic winches, and in particular to a dual hydraulic winch control device and system. Background Technology

[0002] Hydraulic winches, as essential vehicle-mounted rescue equipment, play a crucial role in scenarios such as rescuing vehicles stuck in traffic and towing heavy objects. However, the core components of existing hydraulic winches, such as control valves, control boxes, and cylinders, are mostly independently and separately arranged, connected by numerous hydraulic and air pipes. This not only occupies a large amount of vehicle space but also results in a chaotic and disorganized pipe layout. This structure increases the difficulty of component installation and pipe connection, prolonging equipment assembly time. Furthermore, during subsequent maintenance and repair, the messy pipes make troubleshooting difficult, hindering the rapid location of leaks and blockages, severely impacting the timeliness of rescue operations.

[0003] Furthermore, hydraulic winches that only support mechanical operation require operators to manually control the winch's start, stop, and direction of travel near the winch. This control method has significant limitations: first, operators must be in close proximity to the work area, making them highly susceptible to injury should accidents such as rope breakage or falling loads occur; second, in complex rescue scenarios (such as confined spaces or dangerous areas), operators cannot easily approach the winch, hindering normal operation and impacting rescue efficiency. Therefore, there is an urgent need to design a hydraulic winch control scheme that is compact, has well-organized piping, and combines mechanical operation with remote control capabilities. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a dual hydraulic winch control device that achieves integrated device layout and orderly pipeline connection, while also having the function of mechanical operation and remote control of the hydraulic winch.

[0005] Technical Solution: To achieve the above objectives, the present invention provides a dual hydraulic winch control device, comprising a mounting bracket installed on a vehicle platform. The mounting bracket is equipped with a left winch control valve, a right winch control valve, an electrical control box, and a protective net. It also includes a remote control box. The hydraulic interfaces of the left and right winch control valves are respectively connected to the hydraulic lines of the left and right hydraulic winches. The pneumatic interfaces of the left and right winch control valves are connected to the air ports of the electrical control box. The remote control box is connected to the signal port of the electrical control box via a cable. The operating state of the left or right winch control valve is directly controlled by an operating handle, or remotely controlled by the electrical control box based on the output signal from the remote control box, thereby enabling the operation of the left or right hydraulic winch.

[0006] Preferably, the protective net is raised and lowered by a rodless lifting cylinder, which includes a slider and a linear bearing. The protective net is fixed on the slider, and the linear bearing is fixed on the mounting bracket.

[0007] Preferably, the slider is fitted with a protective net via a connecting seat.

[0008] Preferably, the rodless lifting cylinder controls its working state through a protective control valve.

[0009] Preferably, the air outlet of the protective control valve is connected to the air inlet and air outlet of the rodless lifting cylinder via an air pipe.

[0010] Preferably, the remote control box is equipped with control buttons and status indicator lights.

[0011] Beneficial Effects: This utility model has the following advantages: 1. The integrated installation of various components through the mounting bracket reduces the space occupied by the device, while making the pipeline connection path neat, reducing the installation difficulty and troubleshooting cost, and improving the ease of device maintenance; 2. It has both mechanical operation and remote control functions. Operators can choose the appropriate operation mode according to the operation scenario. For example, precise control can be achieved through the mechanical handle when working at close range, and remote control can be used to move away from the operation area in dangerous scenarios. Combined with the protection of the safety net, the safety of the operation is improved; 3. The overall structure of the device is stable and can be adapted to different models of vehicle-mounted hydraulic winches. The remote control distance meets the needs of most rescue scenarios, effectively improving the efficiency and reliability of rescue operations. Attached Figure Description

[0016] The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings.

[0017] like Figures 1-3As shown, a dual hydraulic winch control device includes: a mounting bracket 1, a left winch control valve 2 and its left winch mechanical handle 21 and left winch pneumatic interface 22, a right winch control valve 3 and its right winch mechanical handle 31 and right winch pneumatic interface 32, an electrical control box 4 and its electrical control box air port I 41 and electrical control box air port II 41, a rodless lifting cylinder 5 and its slider 51 and linear bearing 52, a protective net 6 and its connecting seat 61, a protective control valve 7 and its protective control lever 71, a control cable 8, a remote control box 9 and its control button 91 and status indicator light 92.

[0018] The structural connections include: left winch control valve 2 and right winch control valve 3 symmetrically fixed in the middle area of ​​mounting bracket 1, with the left winch mechanical handle 21 and right winch mechanical handle 31 facing the direction convenient for the operator. Electrical control box 4 is fixed to one end of mounting bracket 1, and protective control valve 7 is fixed to the side of electrical control box 4. Rodless lifting cylinder 5 is bolted to the other side of mounting bracket 1, ensuring that the movement direction of its slider 51 is vertical, and a protective net 6 is installed on slider 51 via connecting seat 61. Mounting bracket 1 is fixed at a designated position on the vehicle platform.

[0019] The piping connections include: connecting the left winch pneumatic interface 22 to the air port I41 of the electrical control box via a high-pressure air pipe, and connecting the right winch pneumatic interface 3 to the air port II41 of the electrical control box. The outlet of the protective control valve 7 is connected to the inlet and outlet of the rodless lifting cylinder 5 via an air pipe. The remote control box 9 is connected to the signal interface of the electrical control box 4 via a control cable 8. The hydraulic interfaces of the left winch control valve 2 and the right winch control valve 3 are connected to the hydraulic lines of the left and right hydraulic winches, respectively.

[0020] Operators can independently control the start, stop, forward and reverse rotation (i.e., rope winding and unwinding) of the left or right hydraulic winch by manually operating the left winch mechanical handle 21 or the right winch mechanical handle 31. The mechanical handles are made of non-slip and wear-resistant material and are equipped with a gear positioning structure to prevent accidental winch operation due to accidental contact during operation.

[0021] The left winch control valve 2 and the right winch control valve 3 are respectively connected to the air ports of the electrical control box 4 via the left winch pneumatic interface 22 and the right winch pneumatic interface 32. Simultaneously, the remote control box 9 is electrically connected to the electrical control box 4 via a control cable 8. The remote control box 9 is equipped with control buttons 91 (including left winch start / stop and forward / reverse control buttons, and right winch start / stop and forward / reverse control buttons) and status indicator lights 92 (power, fault, winch operating status). The operator can send electrical signals through the remote control box 9, which are transmitted to the electrical control box 4 via the control cable 8. The electrical control box 4 controls the internal solenoid valves to operate according to the signals, thereby outputting compressed air through the air pipes to the pneumatic interfaces of the left / right winch control valves, actuating the valve cores of the left / right winch control valves, and achieving remote control of the left / right hydraulic winches. The control distance of the remote control box can reach 50-100 meters, meeting the needs of long-distance operation in complex scenarios.

[0022] Operators can control the flow of compressed air in the rodless lifting cylinder 5 by manipulating the protective control lever 71, and drive the slider 51 to move the protective net 6 up and down in the vertical direction (the slider 51 of the rodless lifting cylinder 5 cooperates with the linear bearing 52 to ensure that the lifting process of the protective net 6 is smooth and without deviation).

[0023] The protective net 6 is made of high-strength nylon woven mesh, which has sufficient impact resistance. Its lifting and lowering states are linked to the winch operation: when the operator operates the winch through the mechanical handle (close range), the protective net is raised, placing it between the operator and the winch working area, effectively blocking flying debris or broken ropes in case of accidents, and protecting the operator's personal safety; when the winch is operated remotely through the control box (remote range), the protective net is lowered, avoiding the protective net occupying vehicle space, and at the same time not affecting the normal working vision of the winch.

[0024] like Figure 4 As shown, the working principle of the dual hydraulic winch control device is as follows:

[0025] Mechanical control mode (close-range operation): The operator first operates the protective control lever 71 to control the rodless lifting cylinder 5 to drive the protective net 6 to rise to the designated height (above the operator's chest level); then, according to the operation requirements, the operator manually operates the left winch mechanical handle 21 or the right winch mechanical handle 31 to control the rope winding and unwinding of the left / right winches to complete the rescue operation; after the operation is completed, the operator operates the protective control valve 7 to lower the protective net 6.

[0026] Remote control mode (long-distance / hazardous operation): The operator lowers the protective net 6 and carries the remote control box 9 to a safe area; the operator sends a control signal through the control buttons 91 on the remote control box 9 (such as "left winch start - rope winding" "right winch stop" etc.), the signal is transmitted to the electrical control box 4 through the control cable 8, the electrical control box 4 controls the solenoid valve to operate, and delivers compressed air to the corresponding winch control valve to realize remote control of the winch; the operator can observe the winch operation status in real time through the status indicator light 92 on the remote control box 9 to ensure operation safety.

[0027] Maintenance and troubleshooting: Due to the integrated layout of the device and the neat pipelines, during routine maintenance, it is possible to directly observe whether the pipeline connections are loose or leaking. If the winch cannot operate normally, the fault indicator light of the remote control box 9 can be used to determine whether the fault is in the electrical control box 4 or the control cable 8. Then check whether the air pipe connection is unobstructed, and finally check whether the valve core of the winch control valve is stuck, which greatly shortens the troubleshooting time.
