Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic chassis installation, in particular to a self-propelled hydraulic station support platform. Background Technique

[0002] A self-propelled hydraulic support platform is a device integrating the functions of walking and hydraulic support. It usually consists of a chassis, a walking mechanism, a hydraulic system, a support structure, an operation control system, etc., to achieve stable lifting and lowering, as well as the support of heavy objects, and can provide an operator with a safe, stable and flexibly adjustable height working platform, improving work efficiency and operation safety.

[0003] A self-propelled hydraulic support platform is a device specially designed for the assembly operation of large-tonnage excavator chassis. The walking mechanism enables the platform to move flexibly and autonomously in the assembly workshop or construction site, facilitating quick arrival at the designated assembly position. During the assembly process of the large-tonnage excavator chassis, the platform can provide an appropriately high, stable and safe working plane for assembly workers, facilitating various complex assembly operations, greatly improving the assembly efficiency and quality, and at the same time ensuring the safety of operators.

[0004] In the existing self-propelled hydraulic support platform, the lower part of the large-tonnage excavator adopts a split structure, and the total weight of the lower part of the vehicle model exceeds the load-bearing capacity of the crane, making it impossible to carry out hoisting operations. When assembling with jacks on both sides, it is not easy to synchronize, posing great safety hazards, with weak crane load-bearing capacity, increasing the assembly difficulty, reducing the operation efficiency, and having problems such as asynchronous operation of the support device and high safety risks. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a self-propelled hydraulic station support platform, aiming to improve the problems of asynchronous operation of the support device and high safety risks in the existing technology.

[0013] As a further description of the above technical solution:

[0014] A fixing frame is fixedly connected to the right side of the outer wall of the frame, and a sliding door is slidably connected to the inside of the fixing frame.

[0015] The utility model has the following beneficial effects:

[0016] In the utility model, the steering wheel structures at the four corners can enable the workstation to adapt to different working environments for in-plant assembly or outdoor maintenance.

[0026] Specifically, the working support plate 2 is fixedly installed on the inner bottom wall of the frame 1, and the flange 14 is connected to the oil cylinder 3 to form a hydraulic lifting system to ensure synchronous and stable lifting. The connecting shaft 4 and the support seat 6 are installed on the top of the oil cylinder 3 to achieve floating connection and surface contact support. The pressure plate 7 passes through the outer wall of the oil cylinder 3 to fix the support sleeve 5 and the support rod 8. The guide copper sleeve 9 and the guide sleeve 10 provide precise guidance. The structural design meets the requirements of movement and stability. The bottom end of the support rod 8 is connected to the steering wheel 11 to achieve omnidirectional self-propulsion. The control cabinet provides dual-mode operation to adapt to different working environments and improve efficiency and user experience. The baffle 17 is installed on the outer wall of the frame 1 to protect the internal equipment from damage.

[0027] Refer to Figure 1 , Figure 2 and Figure 3, a numerical control cabinet 12 is installed on the front side of the outer wall of the frame 1.

[0028] Specifically, a numerical control cabinet 12 is installed on the front outer wall of the frame 1. A plurality of control buttons 13 are designed on the front side of the numerical control cabinet 12 to facilitate user operation and increase the convenience of structural operation. In addition, the outer walls of a plurality of support rods 8 are slidably connected to a fixing frame 15, and a plurality of first threaded holes 16 are provided on the outer walls of the fixing frame 15 to increase the structural stability and ensure the safety during construction. A fixing frame 19 is fixed to the right outer wall of the frame 1, and a sliding door 20 is slidably connected to the inside thereof to facilitate user equipment maintenance and repair.

[0029] Working principle: The inner bottom wall of the frame 1 is connected to the working support plate 2 by means of fixed connection, ensuring the stability of the working support plate 2. Flanges 14 are fixed on both the front and rear sides of the top of the working support plate 2 to enhance the structural stability. The top of the flange 14 is connected to the oil cylinder 3. The hydraulic lifting system consists of a double-acting electric pump, an internally controlled self-locking oil cylinder 3, a shunt flow control valve, etc., ensuring synchronous, stable lifting and falling of the double oil cylinders 3. Connecting shafts 4 are installed at the tops of both oil cylinders 3, and support seats 6 are provided at the tops of the connecting shafts 4. The support head is floatingly connected to the hydraulic oil cylinder 3 and can swing at a certain angle to ensure that the support surface is always in surface contact with the workpiece surface, guaranteeing the strength and stability of the support. A pressing plate 7 penetrates through the outer wall of the oil cylinder 3, and a support sleeve 5 is fixed in the middle of the pressing plate 7 to protect the pressing plate 7 from wear during the lifting and lowering of the structure.

Guide copper sleeves 9 are installed on the outer walls of the support rods 8, and guide sleeves 10 are installed on the outer walls of the guide copper sleeves 9, providing more precise guidance for the overall structure. The structure of the "shoulder pole" type enables the support legs to be axially fixed through the guide copper sleeves 9. During movement, the frame 1 is raised above the steering wheels 11 by pressing down the hydraulic oil cylinder 3 to meet the movement requirements of the workstation. During work, due to the self-weight of the workpiece and under the limitation of the guide copper sleeves 9, the steering wheels 11 are pulled into the frame 1 to avoid the steering wheels 11 from bearing the working pressure, enabling the bottom of the frame 1 to be in overall contact with the ground and ensuring the stability during hydraulic work. Finally, the bottom ends of the support rods 8 are firmly fixedly connected to the steering wheels 11, enabling a stable and reliable omnidirectional self-propelling function. The use of a control cabinet and a remote control in dual modes allows the workstation to adapt to different working environments such as in-plant assembly or outdoor maintenance, not only ensuring the structural stability and durability but also improving the overall work efficiency and user experience, making the overall structure more efficient and convenient.
