Technical Field

[0001] The utility model relates to a safety protection device, in particular to a safety protection device for subway tunnel construction. Background Art

[0002] Tunnel construction refers to the general term for the construction methods, construction techniques and construction management of tunnels and underground caverns. It usually involves excavating soil and rock from the stratum to form an underground space that meets the designed cross-section, and carrying out the necessary support and lining to control the deformation of the tunnel surrounding rock and ensure the safety of tunnel construction and long-term safe use.

[0003] During subway tunnel construction, safety measures are crucial for ensuring worker safety and the smooth progress of the project. Traditionally, safety devices used in subway tunnel construction have been simple in structure and limited in function, typically providing only basic warnings and failing to meet the diverse demands of complex construction environments. For example, traditional safety devices are often fixed and difficult to adjust, and lack effective splicing components between devices, resulting in time-consuming and labor-intensive splicing and difficulty adapting to changes on the construction site.

[0004] Based on this, it is necessary to design a safety protection device for subway tunnel construction that can be efficiently spliced ​​and easily adjusted in position. Utility Model Content

DETAILED DESCRIPTION

[0019] The following describes embodiments of the present invention with reference to the accompanying drawings.

[0020] Example: A safety protection device for subway tunnel construction, such as Figures 1-4As shown, it includes a base plate 1, a connecting plate 2, a mouth frame 3, a warning horizontal plate 5 and a clamping component. An anti-skid pad 13 is provided at the bottom of the base plate 1. The setting of the anti-skid pad 13 is conducive to increasing the friction coefficient between the base plate 1 and the ground, thereby improving the stability of the device; connecting plates 2 are installed on both sides of the top of the base plate 1 symmetrically, and an inverted L-shaped plate is installed in the middle of the connecting plate 2. The mouth frame 3 is rotatably installed on the inverted L-shaped plate, and warning horizontal plates 5 are evenly spaced between the longitudinal sides of the mouth frame 3. The warning horizontal plates 5 are made of a plastic material with light weight and good toughness, which is conducive to realizing a lightweight setting of the device. A clamping component is provided between the adjacent mouth frames 3 and connected by the clamping component The clamping assembly includes a clamping sleeve 9 installed on one longitudinal side of the mouth frame 3 and a concave block 10 on the other side. The clamping sleeve 9 can be movably inserted into the concave block 10. The effective connection between adjacent mouth frames 3 is achieved by movably inserting the clamping sleeve 9 into the concave block 10. This connection method has the characteristics of simple operation and high assembly efficiency. The clamping sleeve 9 and the concave block 10 are both connected to the warning horizontal plate 5 on the mouth frame 3. It is worth noting that the clamping sleeve 9 is slidably connected to the corresponding warning horizontal plate 5. Damping is provided at the sliding connection between the clamping sleeve 9 and the warning horizontal plate 5 to avoid the clamping sleeve 9 from independently moving up and down, thereby ensuring the stability of the clamping sleeve 9 after it is inserted into the concave block 10.

[0021] like Figure 2 As shown, a torsion spring 4 is provided between the bottom horizontal section of the mouth frame 3 and the top horizontal section of the inverted L-shaped plate. The two ends of the torsion spring 4 are respectively connected to the mouth frame 3 and the inverted L-shaped plate. When the mouth frame 3 rotates, the torsion spring 4 drives the mouth frame 3 to rotate and reset quickly to prevent the device from deviating from the original position due to accidental collision.

[0022] like Figure 2 As shown, hollow balls are evenly spaced in the transverse notch of the warning horizontal plate 5, and warning strips are pasted on the outside of the hollow balls. The hollow balls are used to buffer the external force that impacts the warning horizontal plate 5 and the mouth frame 3, thereby protecting the warning horizontal plate 5 and the mouth frame 3, and protecting the device itself from damage, thereby ensuring the safety of construction workers.

[0023] like Figure 3 As shown, on both sides of the connecting plate 2 with the inverted L-shaped plate as the center, there are sliding connections with movable frames 6. The movable frames 6 are slidingly arranged in the longitudinal grooves of the side walls of the base plate 1. The top of the movable frame 6 is slidingly connected with a clamping rod 8. The clamping rod 8 is arranged in a "Z" shape. The end of the clamping rod 8 away from the movable frame 6 is detachably connected to the inverted L-shaped plate. An elastic member 7 is arranged between the clamping rod 8 and the connecting plate 2. Under the normal condition of the elastic member 7, the clamping rod 8 abuts against the top of the inverted L-shaped plate. The clamping rod 8 moves downward to compress the elastic member 7 and drive the movable frame 6 to move downward, thereby replacing the base plate 1 with the movable frame 6 to support the entire device, thereby realizing the rapid conversion of the device from a fixed state to a mobile state, greatly improving the flexibility and adaptability of the device, and facilitating adjustment of the position according to actual construction conditions.

[0024] like Figure 1 As shown, a fixing sleeve 11 is installed on the horizontal section of the top of the mouth frame 3, and warning lights 12 are evenly spaced on the fixing sleeve 11. The warning lights 12 are LED lights, and the light colors are red and yellow. The red and yellow lights have extremely strong penetrability and good warning effect, thereby enhancing the visibility and penetration of the warning signal. It can be clearly seen even in adverse weather conditions. The LED light has the characteristic of high brightness, which provides reliable safety protection for construction at night or under low light conditions.

[0025] When in use, place the mouth frame 3 just above the center line of the bottom plate 1, so that the mouth frames 3 are in the same straight line, and then slide the clamping sleeves 9 on the two adjacent mouth frames 3 upward until the concave block 10 is just below the clamping sleeve 9, and the clamping sleeve 9 is downwardly clamped into the concave block 10, thereby realizing a convenient connection of the mouth frames 3; when it is necessary to move the protective device, pull the clamping rod 8 in the direction away from the inverted L-shaped plate, and then use a tool to tilt one side of the bottom plate 1 upward, and then press the clamping rod 8 downward, and the clamping rod 8 pushes the moving frame 6 to move downward, and the elastic member 7 is compressed and deformed, so that the moving wheel on the moving frame 6 contacts the ground and The base plate 1 is replaced to support the entire protective device, and the movable frames 6 on both sides of the base plate 1 are moved down until the clamping rod 8 moves down to the bottom of the mouth frame 3, and then the clamping rod 8 is pushed toward the direction of the inverted L-shaped plate so that the clamping rod 8 is stuck at the bottom of the mouth frame 3. At this time, the device can be easily moved by the movable wheels on the movable frames 6; after the device is moved into place, the clamping rod 8 is pulled away from the inverted L-shaped plate. Under the action of the elastic force of the elastic member 7, the elastic member 7 is reset, and the movable frame 6 is reset upward. The base plate 1 replaces the movable frame 6 and contacts the ground, and the base plate 1 and the anti-slip pad 13 at the bottom of the base plate 1 provide stable support for the device.
