[0027] See also Figure 1-3A protective device for railway engineering construction, comprising a U-shaped frame 1, a sub-frame 2, a first protective net 3, a second protective net 4, an electric telescopic rod 6, a support column 7 and a fixing device, wherein the sub-frame 2 is arranged on the top surface of the U-shaped frame 1, the first protective net 3 is fixed in the frame of the U-shaped frame 1, the bottom surface of the sub-frame 2 is located in the frame of the U-shaped frame 1 and is fixed with the second protective net 4, the electric telescopic rod 6 is arranged inside the inner side of the U-shaped frame 1 on both sides of the second protective net 4, two support columns 7 are fixed to the bottom surface of the sub-frame 2 on both sides of the second protective net 4, and the fixing device is arranged on the outer side of the top end of the U-shaped frame 1 near the sub-frame 2;

[0028] The fixing device includes a slider 8, an insert rod 12, a baffle 13 and a pull block 14. The slider 8 is fixed to the bottom of the support column 7 away from the second protective net 4. A slot 11 is opened on the outside of the top of the U-shaped frame 1 near the sub-frame 2. The insert rod 12 is inserted into the slot 11 of the U-shaped frame 1. A baffle 13 is fixed on the outer periphery of the insert rod 12 in the slot 11, and a pull block 14 is fixed to the end of the insert rod 12 away from the support column 7.

[0029] In this embodiment, mounting grooves 5 are provided on both sides of the interior of the U-shaped frame 1. The top end of the electric telescopic rod 6 is fixed to the bottom surface of the support column 7. The electric telescopic rod 6 and the support column 7 are installed in the mounting groove 5 of the U-shaped frame 1. The design of the mounting groove 5 not only provides a stable installation position for the electric telescopic rod 6 and the support column 7, but also ensures the compactness of the overall structure, avoids mutual interference between components, and improves the stability and durability of the device.

[0030] In this embodiment, a sliding groove 10 corresponding to the slider 8 is formed on one side of the mounting groove 5 of the U-shaped frame 1 near the slot 11 , and an end of the insertion rod 12 near the sliding groove 10 is formed as a trapezoidal block with an inclined surface downward.

[0031] In this embodiment, a socket 9 corresponding to the insertion rod 12 is provided in the middle of the side of the slider 8 away from the support column 7, and an inclined surface corresponding to the trapezoidal block of the insertion rod 12 is provided above the slider 8. The design of the socket 9 and the inclined surface cooperates with the trapezoidal block of the insertion rod 12 to ensure that the insertion rod 12 can be smoothly inserted and locked during the movement of the slider 8. At the same time, the inclined surface design also plays a guiding role, so that the insertion rod 12 can more easily enter the socket 9, thereby improving the reliability and convenience of fixation.

[0032] In this embodiment, the first protective net 3 and the second protective net 4 are installed side by side between the U-shaped frame 1 and the sub-frame 2. The specifications of the second protective net 4 are consistent with those of the first protective net 3, and the height of the first protective net 3 is four-fifths of the height of the second protective net 4.

[0033] In this embodiment, a spring is provided on the periphery of the insertion rod 12 between the slot 11 and the baffle 13. The setting of the spring provides additional locking force for the insertion rod 12, ensuring that the insertion rod 12 can maintain its position firmly after being inserted into the socket 9, and preventing it from loosening due to external force. A battery 18 is installed at the bottom of the U-shaped frame 1. The battery 18 provides power support for electric components such as the electric telescopic rod 6, ensuring the normal operation of the device.

[0034] In this embodiment, reflective strips 17 are bonded to both sides of the two surfaces of the U-shaped frame 1 and the two side surfaces of the sub-frame 2. The reflective strips 17 improve the visibility of the device at night or in low-light environments, thereby enhancing construction safety. Connecting blocks 15 are fixed on both sides of the bottom surface of the U-shaped frame 1, and pulleys 16 are installed on both sides of the two side surfaces of the connecting block 15. The design of the connecting block 15 and the pulley 16 enables the entire device to be easily moved and positioned, thereby improving construction efficiency. At the same time, the pulley 16 also reduces the friction and damage of the device to the ground during movement, thereby protecting the construction environment.

[0035] Beneficial effects:

[0036] This type of protective device for railway engineering construction has enhanced adaptability and stability through the stable structure of the U-shaped frame 1 and the sub-frame 2, combined with the electric telescopic rod 6 to adjust the height of the second protective net 4. The fixing device uses the ingenious design of the slider 8, the plug rod 12 and the slot 11 to achieve rapid fixation of the equipment after the height is adjusted. The addition of reflective strips 17 and pulleys 16 improves the night warning effect and mobility. The overall design effectively solves the problems of inconvenient adjustment, poor stability and insufficient warning of traditional protective devices, thereby improving construction safety and efficiency.

[0037] Working principle:

[0038] A solid foundation is constructed by the U-shaped frame 1 and the sub-frame 2. The electric telescopic rod 6 is installed in the mounting groove 5 of the U-shaped frame 1 to support and drive the second protective net 4 to rise and fall to adapt to different construction environment requirements. When the second protective net 4 rises to the highest point, the fixing work is carried out. The slider 8 slides to the highest point along the slide groove 10. The trapezoidal block of the insertion rod 12 is automatically aligned and inserted into the socket 9 under the action of the inclined surface of the slider 8. The spring ensures that the insertion rod 12 is firmly locked to achieve rapid fixation after height adjustment. The reflective strip 17 enhances visibility at night, and the pulley 16 facilitates the movement and positioning of the entire device. This equipment effectively improves the flexibility, stability and safety of construction protection through electric adjustment and ingenious fixing mechanism, combined with reflective and mobile design.
