Description

Technical Field

[0001] This utility model belongs to the technical field of protective door panels for engineering machinery, specifically relating to durable protective door panels for engineering machinery. Background Technology

[0002] Protective door panels for construction machinery are important components installed on construction machinery to protect critical equipment parts, operators, and improve the overall safety and reliability of the equipment. They are typically made of high-strength materials and have multiple functions, capable of resisting external impacts, abrasion, corrosion, and the effects of harsh environmental conditions on the construction machinery.

[0003] The main function of protective gate panels is to protect critical components of construction machinery, such as engines, hydraulic systems, and electrical equipment, from impacts, scratches, and wear from external objects, reducing equipment failure rates and extending equipment lifespan. They also protect operators by preventing them from coming into contact with dangerous parts, such as rotating gears and chains, during equipment operation, thus reducing the occurrence of accidents. In the actual assembly of construction machinery protective gate panels, the current market commonly uses a hook-and-sleeve assembly method. While this traditional structure offers some ease of installation, it has significant drawbacks. When the protective gate panel is subjected to high-frequency vibrations from the construction machinery during operation, external impacts during work, or prolonged exposure to bumpy road conditions, the connection between the sleeve and the hook will experience relative displacement due to repeated stress, leading to noticeable shaking and wear at the contact point between the sleeve's inner wall and the hook. Long-term wear not only enlarges the sleeve's aperture, causing loosening of the connection between the protective gate panel and the main body of the construction machinery, but also significantly reduces the protective performance of the protective gate panel. Utility Model Content

[0004] The purpose of this utility model is to provide a durable protective door panel for construction machinery, aiming to solve the problem that in the current market, the commonly used assembly method for protective door panels of construction machinery is the combination of hooks and sleeves. While this traditional structure has a certain degree of ease of installation, it has significant drawbacks. When the protective door panel is subjected to high-frequency vibrations during the operation of construction machinery, external impacts during operation, or long-term exposure to bumpy road conditions, the connection between the sleeve and the hook will experience relative displacement due to repeated stress, resulting in significant shaking and wear at the contact point between the inner wall of the sleeve and the hook. Long-term wear not only enlarges the sleeve aperture, causing loosening of the connection between the protective door panel and the main body of the construction machinery, but also significantly reduces the protective performance of the protective door panel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a durable protective door panel for engineering machinery, comprising a protective door panel frame and a warning sign installed on the surface of the protective door panel frame, wherein mounting seats are installed on both sides of the protective door panel frame, a mounting block is connected to the bottom surface of the mounting seat, a support rod is connected to one side of the mounting block, and a support is connected to the bottom end of the support rod;

[0006] An adjusting rod is connected to an opening on one side of the mounting base, and a movable plate is connected to the other end of the adjusting rod. An adjusting spring is connected to the end of the movable plate near the adjusting rod, and an adjusting buckle is connected to the side of the movable plate opposite to the adjusting rod.

[0007] As a preferred embodiment of the durable engineering machinery protective door panel of this utility model, the protective door panel frame is fitted and connected to the mounting block on one side of the support rod via a mounting base, and the opening size of the bottom surface of the mounting base matches the surface size of the mounting block.

[0008] As a preferred embodiment of the durable protective door panel for engineering machinery of this utility model, one end of the adjusting spring relative to the movable plate is connected to the inner wall of the mounting base opening, the adjusting spring and the movable plate form an elastic telescopic structure, and the adjusting buckle and the opening on one side of the mounting block form a fitting structure.

[0009] As a preferred embodiment of the durable protective door panel for engineering machinery of this utility model, a safety net frame is installed on the back side of the protective door panel frame, a docking plate is connected to the bottom surface of the safety net frame, and a docking seat is installed on the side of the protective door panel frame near the docking plate.

[0010] As a preferred embodiment of the durable engineering machinery protective door panel of this utility model, the safety mesh frame is made of woven metal mesh, the top of the safety mesh frame is connected to an assembly plate, and the inner side of the protective door panel frame near the assembly plate is connected to a fixing block.

[0011] As a preferred embodiment of the durable protective door panel for engineering machinery of this utility model, a locking pin is connected through the surface of the fixing block, and a locking hole is opened at one end of the assembly plate near the locking pin. The locking pin passes through the fixing block and is threadedly connected to the locking hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention connects the mounting base on the side of the protective door frame with the mounting block on the surface of the support rod. Simultaneously, pulling the adjusting rod on one side of the mounting base causes the movable plate tension adjustment spring to stretch and deform, which in turn moves the adjusting buckle. When the mounting base and the mounting block are stably connected, the adjusting rod is released to stabilize the mounting base and the mounting block. This stabilizes the assembly between the protective door frame and the support rod, avoiding the wear and tear that occurs with traditional socket joints, improving assembly convenience, and preventing instability issues associated with protective door panels used in engineering machinery.

[0026] In practical use, by fitting the mounting base 3 and the mounting block 4 together, the protective door panel for construction machinery is prevented from shaking, thereby improving the service life and durability of the protective door panel for construction machinery.

[0027] Preferably, one end of the adjusting spring 9 relative to the movable plate 8 is connected to the inner wall of the opening of the mounting base 3, the adjusting spring 9 and the movable plate 8 form an elastic telescopic structure, and the adjusting buckle 10 and the opening on one side of the mounting block 4 form a fitting structure.

[0028] In practical use, by fitting the adjusting buckle 10 into the opening on one side of the mounting block 4, it is convenient to assemble the protective door frame 1 and the support rod 5 stably.

[0029] Preferably, a safety net frame 11 is installed on the back side of the protective door frame 1, a docking plate 12 is connected to the bottom surface of the safety net frame 11, and a docking seat 13 is installed on the side of the protective door frame 1 near the docking plate 12.

[0030] In practical use, the safety net frame 11 is easily assembled and stabilized on the back of the protective door frame 1 by inserting and connecting the docking plate 12 with the opening on the surface of the docking seat 13.

[0031] Preferably, the safety net frame 11 is made of woven metal mesh, and an assembly plate 14 is connected to the top of the safety net frame 11. A fixing block 15 is connected to the inner side of the protective door frame 1 near the assembly plate 14.
