Description

Technical Field

[0001] The present application relates to the technical field of engineering machinery design and manufacturing, and in particular to a wing plate assembly device for a large electric-driven bulldozer. Background Art

[0002] As mining resources are continuously developed, the working environment of bulldozers is becoming increasingly severe, which not only promotes the evolution of products towards large-scale, but also significantly increases the requirements for the performance of key structural components. At the same time, the market competition in the construction machinery industry is fierce, and customers' expectations for products are constantly upgrading. They not only pay attention to the basic functions of products, but also put forward more stringent standards for appearance design, reliability, maintainability and operational stability.

[0003] The wing plate, as an indispensable key part of the bulldozer structure, plays the role of supporting and protecting other components. Its performance is directly related to the rationality of the overall layout of the bulldozer, the aesthetic appearance and the user's operating experience. Especially in mining construction, facing a more severe working environment, the role of the wing plate is becoming more and more important. However, due to the lack of reasonable layout and standardized design, coupled with considerations on the strength of the wing plate, the wing plate often only has installation holes reserved, which are usually only used to hang tool boxes and other components. The integration is low, which greatly wastes the wing plate space. Summary of the invention

[0004] The purpose of the present application is to provide a large electric drive bulldozer wing panel assembly device, which is used to solve the problem of low integration of bulldozer wing panels and waste of wing panel space in the prior art.

[0005] In order to solve the above technical problems, this application is implemented by adopting the following technical solutions:

[0006] The present application provides a large electric drive bulldozer wing plate assembly device, comprising:

[0007] The wing plate body comprises a first body and a second body which are symmetrically arranged;

[0008] An electrical placement box is provided at the bottom of the wing body and is used to place electrical components of the bulldozer;

[0009] The power supply placement box is arranged on the wing plate body and is used for placing the power supply of the bulldozer.

[0010] In traditional bulldozer designs, electrical components and power supply devices are usually placed in the cab, which greatly limits the effective use of the cab space. However, this solution adds electrical and power supply boxes to the wing body to move some equipment out of the cab, thereby freeing up space inside the cab. This not only improves the spaciousness and comfort of the cab, but also provides operators with a more spacious and barrier-free operating environment, which is conducive to improving work efficiency and operational safety.

[0011] In addition, electrical components and power supply devices will generate a certain amount of heat during operation. If they are in a closed cab for a long time, the temperature may rise, affecting the performance and life of the equipment. Placing the electrical and power supply boxes on the wing body is conducive to the heat dissipation of these devices and reduces the risk of overheating. At the same time, this design also facilitates the daily maintenance and overhaul of the electrical system, thereby improving maintenance efficiency and reducing maintenance costs.

[0012] Optionally, the first body and the second body both include: a main board and a first side plate and a second side plate vertically arranged on two opposite sides of the main board, and the first side plate and the second side plate are parallel to each other.

[0013] Optionally, the first side panel, the second side panel and the main panel are formed by bending.

[0014] For large structural parts, welding deformation is an unavoidable problem. Traditional welding processes often require precise alignment and welding between multiple parts, which is not only complicated to operate, but also prone to welding deformation, affecting the overall quality and appearance of the product. However, the bending forming process can pre-process the side panels and main panels into the required shape and angle, greatly reducing the difficulty in manufacturing.

[0015] The first side plate, the second side plate and the main plate manufactured by the bending forming process have a more compact and firm structure. The reinforcing rib structure formed at the bend can significantly improve the strength and rigidity of the wing plate body, so that it can better withstand the various forces and vibrations generated by the bulldozer during operation. This not only extends the service life of the wing plate, but also improves the overall stability and reliability of the bulldozer.

[0016] In addition, the wing body manufactured by the bending forming process has a flatter and smoother appearance. The smooth transition lines formed at the bends are coordinated with the overall style of the machine, improving the overall aesthetics and visual effect of the bulldozer.

[0017] Optionally, the electrical placement box includes a bottom plate, which is located at the bottom of the main board. The electrical placement box is formed by enclosing the bottom plate, the first side plate, the second side plate and the main board. The main board is provided with an electrical inspection port connected to the electrical placement box.

[0018] In this solution, the design of the wing plate body not only enhances the lateral stability of the wing plate, but also provides the necessary enclosure structure for the electrical placement box and the power placement box. The electrical placement box is enclosed by the bottom plate, the first side plate, the second side plate and the main board. It not only ensures the safe placement of electrical components, but also provides necessary protection to prevent external factors such as dust and moisture from damaging the electrical components. In order to facilitate the inspection and maintenance of electrical components, the main board is provided with an electrical inspection port connected to the electrical placement box. This allows maintenance personnel to easily access the internal electrical components, greatly improving maintenance efficiency and reducing maintenance costs.

[0019] Optionally, the power supply box includes a power supply cover arranged on the first body, the power supply cover has an opening on one side relative to the second body, a first power supply box with a top opening is provided in the power supply cover, first fastening parts are provided on two opposite sides of the first power supply box, screw holes are provided on the first fastening part, a first fixing plate is provided on the opening side of the first power supply box, and a first bolt threadedly connected to the first fastening part is rotatably connected to the first fixing plate.

[0020] When in use, place the bulldozer battery in the first power box, and drive the first fixing plate to move by turning the first bolt, thereby pressing the power supply to ensure that the power supply will not loosen or shift during use. Otherwise, the power supply can be easily removed. This solution can fix the power supply through a simple knob operation, without complicated installation steps or tools, and facilitates daily maintenance and repair work.

[0021] Optionally, a second power supply box with a top opening is further provided in the power supply cover, second fastening parts are provided on two opposite sides of the second power supply box, screw holes are provided on the second fastening parts, a bracket is provided on the second power supply box, a power supply bearing plate is provided on the bracket, the power supply bearing plate is located on the opening side of the second power supply box, a second fixing plate is provided between the second power supply box and the power supply bearing plate, a third fixing plate is provided on the side of the power supply bearing plate facing away from the second power supply box, a second bolt is provided on the third fixing plate, the second bolt passes through the third fixing plate, the second fixing plate and is threadedly connected to the second fastening part, an adjusting nut is threadedly connected to the second bolt, and the adjusting nut is located on the side of the third fixing plate facing away from the second power supply box.

[0022] When in use, place the first battery in the second power box. Place the second battery on the power carrier plate. Tighten the second bolt to drive the third fixing plate to move, and press the battery on the power carrier plate between the power carrier plate and the third fixing plate. Then, tighten the third fixing plate by screwing the adjustment nut to press the battery in the second power box. The design of the second power box and the power carrier plate can accommodate two batteries.

[0023] Optionally, a third power box is provided on the side of the second power box relative to the opening of the power cover, the top of the third power box is open, and the orthographic projection of the second fixing plate located on the third power box is located in the opening of the third power box. By moving the second fixing plate, not only the battery in the second power box but also the battery in the third power box can be pressed tightly.

[0024] The power storage box design is suitable for large equipment that needs to work continuously for a long time. Among them, the battery is a key power source, and its storage and fixation are particularly important. This solution can accommodate four complete machine batteries in a limited space by rationally arranging the first power box, the second power box, the power carrier board and the third power box. In this solution, users can manage and maintain the batteries more conveniently, improving the reliability and operation efficiency of the equipment. At the same time, the compact structural design also saves space, making the entire equipment neater and more efficient.

[0025] Optionally, it also includes a fixing component, which includes a support seat and a connecting member, wherein there are multiple support seats, and the multiple support seats are symmetrically arranged on the side walls of the opposite sides of the first body and the second body; the connecting member is used to connect the first body and the second body, and the connecting member includes a support plate connected to the support seats on the first body and the second body respectively, and a connecting plate fixedly connected to the support plate, and the connecting plate is provided with a fixing plate for fixing the installation of the cab.

[0026] Since the wing panel body carries many components, there are high requirements for its strength and installation and fixing methods. In this solution, the wing panel body is fixedly installed on the bulldozer main frame through multiple support seats, which ensures the overall support strength of the wing panel assembly and strengthens the coordination with the whole machine and the main frame. In addition, this solution also connects the first body and the second body through a connecting piece, which increases the overall stability of the wing panel body. And the fixing plate on the connecting piece provides a cab fixing point, which simplifies the installation process and improves safety.

[0027] Compared with the prior art, the beneficial effects achieved by the present application are as follows: the present application moves some equipment out of the cab by adding an electrical placement box and a power placement box to the wing panel body, thereby freeing up the internal space of the cab. This not only improves the spaciousness and comfort of the cab, but also provides operators with a more spacious and barrier-free operating environment, which is conducive to improving work efficiency and operational safety, and increases the functionality of the wing panel body. At the same time, this design also facilitates the daily maintenance and overhaul of the electrical system, thereby improving maintenance efficiency and reducing maintenance costs.

The electrical placement box 2 is arranged at the bottom of the wing body 1, and is used to place the bulldozer electrical components. The power placement box 3 is arranged on the wing body 1, and is used to place the bulldozer power supply.

[0042] In the traditional bulldozer design, electrical components and power supply devices are usually placed in the cab, which greatly limits the effective use space of the cab. However, this solution moves some equipment out of the cab by adding an electrical placement box 2 and a power placement box 3 on the wing body 1, thereby freeing up space inside the cab. This not only improves the spaciousness and comfort of the cab, but also provides a more spacious and barrier-free operating environment for operators, which is conducive to improving work efficiency and operational safety.

[0043] In addition, electrical components and power supply devices will generate a certain amount of heat during operation. If they are in a closed cab for a long time, the temperature may rise, affecting the performance and life of the equipment. Placing the electrical storage box 2 and the power storage box 3 on the wing body 1 is conducive to the heat dissipation of these devices and reduces the risk of overheating.

Further, the first side plate 102, the second side plate 103 and the main board 101 are formed by bending.

[0045] For large structural parts, welding deformation is an unavoidable problem. Traditional welding processes often require precise alignment and welding between multiple parts, which is not only complicated to operate, but also prone to welding deformation, affecting the overall quality and appearance of the product. However, by adopting the bending forming process, the side panels and the main board 101 can be processed into the required shape and angle in advance, greatly reducing the difficulties in production and manufacturing.

[0046] The first side plate 102, the second side plate 103 and the main plate 101 manufactured by the bending forming process have a more compact and firm structure. The reinforcing rib structure formed at the bending position can significantly improve the strength and rigidity of the wing plate body 1, so that it can better withstand various forces and vibrations generated by the bulldozer during operation. This not only prolongs the service life of the wing plate, but also improves the overall stability and reliability of the bulldozer.

[0047] In addition, the wing plate body 1 manufactured by the bending forming process has a flatter and smoother appearance. The smooth transition lines formed at the bending part are coordinated with the style of the whole machine, which improves the overall aesthetics and visual effect of the bulldozer.

The bottom plate 21 is connected to the first side plate 102, the second side plate 103 and the main board 101 by welding. Furthermore, the main board 101 is provided with an electrical inspection port 22 connected to the electrical placement box 2.

[0049] The design of the wing plate body 1 not only enhances the lateral stability of the wing plate, but also provides the necessary enclosure structure for the electrical placement box 2 and the power supply placement box 3. The electrical placement box 2 is enclosed by the bottom plate 21, the first side plate 102, the second side plate 103 and the main board 101. It not only ensures the safe placement of electrical components, but also provides necessary protection to prevent external factors such as dust and moisture from damaging the electrical components. In order to facilitate the inspection and maintenance of electrical components, the main board 101 is provided with an electrical inspection port 22 connected to the electrical placement box 2. It enables maintenance personnel to easily access the internal electrical components, greatly improving maintenance efficiency and reducing maintenance costs.

The connecting member 42 includes a support plate 421 connected to the support seats 41 on the first body 11 and the second body 12, and a connecting plate 422 fixedly connected to the support plate 421. The connecting plate 422 is provided with a fixing plate 423 for fixing and installing the cab.

[0051] Since the wing panel body 1 carries many components, there are high requirements for its strength and installation and fixing methods. In this solution, the wing panel body 1 is fixedly installed on the bulldozer main frame through 6 support seats 41, realizing 6-point installation and fixing, ensuring the overall support strength of the wing panel assembly, and strengthening the coordination with the whole machine and the main frame. In addition, this embodiment also connects the first body 11 and the second body 12 through a connecting member 42, thereby increasing the overall stability of the wing panel body 1. And the fixing plate 423 on the connecting member 42 provides a cab fixing point, which simplifies the installation process and improves safety.
