[0028] Please refer to Figures 1-5 The utility model provides a technical scheme: subway tunnel structure protection device, including mounting bracket 1 and the stand 2 of fixed installation in the bottom of mounting bracket 1 both ends, still including,

[0029] Protective glass 4, movably connected between two stands 2;

[0030] The two ends of the protective glass 4 are respectively slidably inserted into the two grooves 3;

[0031] The buffer spring 5 and the damping cylinder 6 are arranged in the horizontal direction and are respectively fixedly connected with the protective glass 4 and the inner wall of the groove 3, the buffer spring 5 is movably sleeved on the damping cylinder 6, and is used for buffering the protective glass 4 which is hit.

[0032] In specific implementation, the mounting frame 1 and the column 2 are installed at the edge of the subway tunnel platform, when a person hits the protective glass 4, the protective glass 4 will compress the buffer spring 5 and slide in the groove 3 at this time, the impact force can be absorbed, after the impact force is absorbed, the protective glass 4 can be slowly rebounded and reset in the groove 3 by cooperating with the damping cylinder 6, so as to realize the buffering effect of the protective glass 4, avoid the problem that the protective glass 4 is broken due to the impact of the person, improve the safety, and prolong the service life.

[0033] Referring to Figures 1-5 The number of the buffer spring 5 is two, and the two buffer springs 5 are respectively arranged at the two ends of the top of the rear side of the protective glass 4. The arrangement of the two buffer springs 5 can not only improve the buffering capacity of the protective glass 4, but also make the two ends of the protective glass 4 bear force uniformly, so as to ensure the normal sliding of the protective glass 4 and avoid the problem of inclination.

[0034] Referring to Figures 1-5 The electric push rod 7 is inlaid in the center of the top of the rear side of the mounting frame 1, the driving end of the electric push rod 7 penetrates through the mounting frame 1 and is fixedly installed with the first scraping piece 8, the second scraping piece 9 is slidably inserted into one side of the first scraping piece 8, the second scraping piece 9 abuts against the protective glass 4, the mounting slot 11 is arranged on one side of the first scraping piece 8, the limiting spring 10 is fixedly installed in the mounting slot 11, the other end of the limiting spring 10 is fixedly connected with the second scraping piece 9, the fixing slot 15 is arranged in the center of the top of the rear side of the mounting frame 1, and the electric push rod 7 is inlaid in the fixing slot 15.

[0035] In specific implementation, on the basis of the above implementation, by turning on the electric push rod 7, the driving end of the electric push rod 7 is elongated to drive the first scraping piece 8 and the second scraping piece 9 to move downward, in this process, the first scraping piece 8 and the second scraping piece 9 will scrape the stones stuck between the protective glass 4 and the inner wall of the groove 3, so as to avoid the problem that the stones stuck between the protective glass 4 and the inner wall of the groove 3 cause the protective glass 4 to not slide normally in the groove 3, and ensure the normal buffering of the subway tunnel structure protection device, it should be noted that, since the second scraping piece 9 is slidably inserted into the mounting slot 11, the protective glass 4 can extrude the second scraping piece 9 to compress the limiting spring 10 and slide in the mounting slot 11 when moving, so as to avoid the problem of movement interference.

[0036] Referring to Figures 1-5 The number of the limiting springs 10 is six, and the six limiting springs 10 are respectively fixedly installed at the four corners and the center position between the installation slot 11 and the second scraping piece 9. The setting of the six limiting springs 10 can guarantee the normal rebound of the second scraping piece 9, so that the second scraping piece 9 is always in abutment with the protective glass 4 when the protective glass 4 does not need to be buffered.

[0037] Referring to Figures 1-5 The bottom of the front side of the stand 2 is provided with a cleaning port 12, the cleaning port 12 is communicated with the sliding groove 3, and the receiving hopper 13 is slidingly inserted into the cleaning port 12. The stones scraped down by the first scraping piece 8 and the second scraping piece 9 will fall into the receiving hopper 13 for collection. When the receiving hopper 13 is full of stones, the receiving hopper 13 can be pulled out of the cleaning port 12 and the sliding groove 3 by pulling the receiving hopper 13, so that the stones in the receiving hopper 13 can be poured out, thereby avoiding the problem that the stones overflow the receiving hopper 13 and are stuck again between the protective glass 4 and the inner wall of the sliding groove 3.

[0038] One side of the receiving hopper 13 is provided with a handle, and the handle is provided with anti-skid lines. When the handle is pulled, the handle can drive the receiving hopper 13 to slide in the cleaning port 12, and the force can be better applied when the receiving hopper 13 is pulled. In addition, the setting of the anti-skid lines can increase the friction force between the hands of the person and the handle, thereby helping to solve the problem of slipping when the handle is pulled.

[0039] Referring to Figures 1-5 The top of the protective glass 4 is provided with a sealing strip 14, and the sealing strip 14 is in abutment with the bottom of the mounting frame 1. The gap between the mounting frame 1 and the protective glass 4 can be filled, which helps to improve the sealing effect.

[0040] Working principle: Before use, first connect the power supply to the electrical appliances involved in the subway tunnel structure protection device to ensure normal power supply and normal operation.

[0041] When in use, the mounting frame 1 and the stand 2 are installed at the edge of the subway tunnel platform. When a person hits the protective glass 4, the protective glass 4 will compress the buffer spring 5 and slide in the sliding groove 3, so that the impact force can be absorbed. After the impact force is completely absorbed, the protective glass 4 can be slowly rebounded and reset in the sliding groove 3 in cooperation with the damping cylinder 6, so that the buffering effect of the protective glass 4 can be realized, the problem of breakage of the protective glass 4 caused by the impact of the person is avoided, the safety is improved, and the service life is prolonged.

[0042] By opening the electric push rod 7, the driving end of the electric push rod 7 can be elongated to drive the first scraping piece 8 and the second scraping piece 9 to move downward, in this process, the first scraping piece 8 and the second scraping piece 9 can scrape the stones stuck between the protective glass 4 and the inner wall of the sliding groove 3, avoid the problem that the stones are stuck between the protective glass 4 and the inner wall of the sliding groove 3 to cause the protective glass 4 to be unable to slide normally in the sliding groove 3, and ensure the normal buffering of the subway tunnel structure protection device, it needs to be explained here that since the second scraping piece 9 is slidingly inserted in the mounting groove 11, the protective glass 4 can extrude the second scraping piece 9 to compress the limiting spring 10 and slide in the mounting groove 11 when moving, and the problem of movement interference can be avoided.

[0043] Finally, the stones scraped by the first scraping piece 8 and the second scraping piece 9 will fall into the receiving hopper 13 for collection, when the receiving hopper 13 is full of stones, the receiving hopper 13 can be pulled out from the cleaning port 12 and the sliding groove 3, the stones in the receiving hopper 13 can be poured out, so that the problem that the stones overflow the receiving hopper 13 and are stuck between the protective glass 4 and the inner wall of the sliding groove 3 again can be avoided.

[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
