DETAILED DESCRIPTION

[0024] like Figures 1 to 4 As shown, a crash-proof guardrail maintenance trolley, a driving frame 3 is provided on one side of a guardrail frame 5, and an operating table 10 is provided on the other side. The guardrail frame 5, the driving frame 3 and the operating table 10 form an inverted U-shaped structure, and the inner sides of the guardrail frame 5, the driving frame 3 and the operating table 10 are all provided with a plurality of supporting wheels, a driving motor 2 is provided on the driving frame 3, and a driving wheel 1 is provided on the lower surface of the driving frame 3, and the driving wheel 1 is connected to the driving motor 2;

[0025] The operating platform 10 and the guardrail frame 5 can only be connected through the fixed frame 8 , and the operating platform 10 is slidably connected to the fixed frame 8 . Electric push rods 9 are provided on both sides of the fixed frame 8 , and the telescopic ends of the electric push rods 9 are connected to the operating platform 10 .

[0026] The guardrail frame 5 is located at the top, which is convenient for construction workers to pass through and protects their safety. A driving motor 2 is provided on one side of the driving frame 3, and the entire maintenance trolley can move autonomously through the driving wheel 1. The operating table 10 is connected to the guardrail frame 5 through the fixed frame 8, and the two are connected in a sliding manner, allowing the operating table to be flexibly raised and lowered.

[0027] The electric push rod 9 is installed on both sides of the fixed frame 8, and its telescopic end is connected to the operating table 10, which can drive the operating table to rise and fall, so that the staff can reach every position of the guardrail and realize a wide range of maintenance area.

[0028] A plurality of supporting wheels are arranged on the inner side of the driving frame 3, the operating platform 10 and the guardrail frame 5 to ensure the smooth operation of the trolley on the anti-collision guardrail.

[0029] The cooperation between the driving motor 2 and the driving wheel 1 gives the trolley the ability to move autonomously, while the electric push rod 9 is responsible for the lifting and lowering of the operating platform 10, so that the staff can flexibly reach every corner of the guardrail and complete a full range of inspection and maintenance work.

[0030] The provision of the guardrail frame 5 not only provides a convenient passage for construction workers, but also provides necessary protection during high-altitude operations, greatly reducing the risk of falling. The ladders added to the drive frame 3 and the fixed frame 8 further facilitate the personnel to go up and down, reduce the preparation time, and improve the overall work efficiency.

[0031] In a preferred embodiment, a plurality of sliding sleeves are disposed on the fixing frame 8, a plurality of sliding rods 1001 are disposed on the operating platform 10, and the sliding rods 1001 are disposed inside the sliding sleeves.

[0032] The operating platform 10 is equipped with a plurality of sliding rods 1001, which are precisely arranged inside the sliding sleeve of the fixing frame 8. Such a design ensures that the operating platform can remain stable during the lifting process, avoids unnecessary shaking or tilting, and thus improves the safety of the staff when working at height.

[0033] When the electric push rod 9 starts and drives the operating platform 10 to rise and fall, the sliding rod 1001 will slide smoothly inside the sliding sleeve. This sliding mechanism not only makes the lifting process of the operating platform smoother, but also ensures the position accuracy of the operating platform at different heights, making it easier for construction workers to accurately align and perform guardrail maintenance tasks.

[0034] In the preferred embodiment, an extension frame 12 is further provided inside the operating table 10, and the bottom of one side of the extension frame 12 is hinged to the bottom of one side of the operating table 10, and a limit baffle 13 is provided at the upper position of one side of the operating table 10. After the bottom plate of the extension frame 12 is rotated to be flush with the bottom plate of the operating table 10, the support rod of the extension frame 12 is upper-positioned against the limit baffle 13.

[0035] The bottom of one side of the extension frame 12 is connected to the bottom of one side of the operating table 10 in a hinged manner, and the extension frame 12 can be rotated and unfolded relative to the operating table 10.

[0036] A limit baffle 13 is specially provided at the upper part of one side of the operating table 10. Its function is to provide support and limit functions when the extension frame 12 is unfolded and reaches the same level as the bottom plate of the operating table, so as to ensure the stability and safety of the extension frame during use.

[0037] In the preferred embodiment, avoidance grooves 1201 are further provided on both sides of the bottom plate of the extension frame 12. When the extension frame 12 needs to be stored back into the operating table 10, the design of the avoidance grooves 1201 plays a key role. During the rotating storage process, the avoidance grooves 1201 can avoid the limit baffles 13, ensuring that the extension frame can be folded smoothly without obstruction.

[0038] In the preferred embodiment, the driving frame 3 is further provided with a battery 11, which is electrically connected to the electric push rod 9 and the driving motor 2. The fixed frame 8 is also connected to one side of the guardrail frame 5 through a diagonal rod 6, and a solar panel 7 is provided on the diagonal rod 6, and the solar panel 7 is electrically connected to the battery 11. The operating table 10 is also provided with a wireless operating handle, which is wirelessly connected to the driving motor 2 and the driving motor 2.

[0039] The battery 11 is located on the drive frame 3 and serves as the main power source for the electric push rod 9 and the drive motor 2, ensuring that the equipment can operate normally without an external power supply. This design allows the maintenance trolley to maintain a high degree of autonomy and flexibility at any location.

[0040] The fixing frame 8 is connected to one side of the guardrail frame 5 through a diagonal tie rod 6, on which a solar panel 7 is installed. The solar panel can not only charge the battery 11 and provide clean and renewable energy, but also reduce the dependence on external electricity and extend the endurance of the equipment, which is particularly important in remote areas or areas where it is difficult to access the power grid.

[0041] Wireless operating handle: It is placed on the operating table 10 and is wirelessly connected to the drive motor 2 and the electric push rod 9. This design provides the possibility of remote control, allowing the operator to perform precise control while away from the equipment, enhancing the convenience and safety of operation, while also reducing the potential risks caused by direct contact with the equipment.

[0042] In the preferred embodiment, a plurality of first support wheels 4 are provided on the lower surface of the guardrail frame 5. The first support wheels 4 are supported on the top of the anti-collision guardrail.

[0043] In a preferred embodiment, a plurality of second support wheels 14 are provided on the inner surface of the fixing frame 8. The second support wheels 14 are supported on the side of the anti-collision guardrail.

[0044] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
