Description

Technical Field

[0001] This utility model relates to the field of tunnel protection technology, specifically to an anti-impact buffer device for transport tunnels. Background Technology

[0002] Roadways are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrian access, and various necessary preparatory works for newly drilled ore extraction by metallurgical equipment. These passages are collectively referred to as roadways.

[0003] In tunnels, railcars are used for transporting minerals. However, these railcars can become uncontrollable and crash into the tunnel, damaging its structure and making it prone to collapse. Sandbags are usually placed in the tunnels for cushioning, but their impact resistance is limited. When impacted, the sandbags can be knocked away, causing secondary collisions and failing to effectively protect the tunnel. Therefore, this application proposes an impact-resistant buffer device for transport tunnels. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the above and / or existing problems in tunnel protection, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an anti-impact buffer device for transport tunnels. The device provides primary buffer support through a buffer spring. After the buffer support plate is compressed, it rotates on the base. The buffer support plate is supported by a buffer, providing secondary buffer support and improving the buffering effect.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] This utility model provides an anti-impact buffer device for transport tunnels. It provides primary buffer support via a buffer spring. After being compressed, the buffer support plate rotates on the base, and the buffer damper supports the buffer support plate, providing secondary buffer support and improving the buffering effect. (See also...) Figures 1-4 It includes: buffer support 100 and buffer bracket 200.

[0029] The buffer support 100 includes a base 110, a buffer support plate 120, a buffer 130, and a through hole 140. The buffer support plate 120 is hinged to the left end of the base 110, and the buffer 130 is hinged between the buffer support plate 120 and the base 110. Multiple through holes 140 are opened on the buffer support plate 120.

[0030] The base 110, the buffer support plate 120 and the buffer 130 form a triangular support structure. The buffer 130 provides buffer support for the buffer support plate 120. The base 110 is installed and fixed on the roadway floor to fix the position of the buffer support 100.

[0031] The buffer bracket 200 is connected to the through hole 140. The buffer bracket 200 includes a movable plate 210, a plug rod 220 and a buffer spring 230. The right side wall of the movable plate 210 is provided with a plug rod 220 inserted into the through hole 140. The buffer spring 230 is provided outside the plug rod 220. The buffer spring 230 is located between the movable plate 210 and the buffer support plate 120.

[0032] The insertion rod 220 can move freely on the through hole 140. When the movable plate 210 is pressed, it moves toward the buffer support plate 120. When the movable plate 210 moves toward the buffer support plate 120, it squeezes the buffer spring 230, which provides buffer support.

[0033] To ensure uniform force distribution, through holes 140 are provided at the four corners of the buffer support plate 120 and at the center of the top of the buffer support plate 120, and the insertion rods 220 are inserted into the through holes 140 at the four corners.

[0034] Since the load of the buffer spring 230 is limited, a protective mechanism 300 is provided between the buffer support plate 120 and the base 110. The protective mechanism 300 includes an air pump 310, an exhaust pipe 320 and an explosion-proof airbag 330. The two ends of the air pump 310 are respectively hinged to the buffer support plate 120 and the base 110. The air pump 310 is connected to the explosion-proof airbag 330 through the exhaust pipe 320. The explosion-proof airbag 330 is located on the left side wall of the buffer support plate 120.

[0035] The exhaust pipe 320 is installed through the through hole 140 at the top center of the buffer support plate 120. When the buffer support plate 120 is tilted, it squeezes the air pump 310, compressing the air pump 310 and discharging the gas in the air pump 310 through the exhaust pipe 320 to the explosion-proof airbag 330, causing the explosion-proof airbag 330 to expand and further buffer and support the movable plate 210.

[0036] To allow space for the retraction of the buffer spring 230, in its natural state, there is a gap between the movable plate 210 and the explosion-proof airbag 330.

[0037] To ensure even force distribution, the buffer 130 is symmetrically arranged on the front and rear sides of the base 110 to provide balanced support.

[0038] Since the base 110 needs to be fixed to the ground, fixing screws are provided on the base 110. The fixing screws are evenly distributed on the front and back sides of the base 110, and the base 110 is fixed to the ground by fixing screws.

[0039] To prevent damage to the equipment due to rigid contact during collisions, a protective pad is provided on the left side wall of the movable plate 210. The protective pad is made of rubber and protects the equipment.

[0040] In practical use, the base 110 is fixed to the ground with fixing screws. When the railcar in the tunnel goes out of control, the car crashes into the movable plate 210. After being compressed, the movable plate 210 moves toward the buffer support plate 120. When the movable plate 210 moves toward the buffer support plate 120, it compresses the buffer spring 230, which provides primary buffer support. At the same time, the buffer spring 230 compresses the buffer support plate 120, causing the buffer support plate 120 to flip. The buffer 130 provides secondary buffer support for the buffer support plate 120. Furthermore, when the buffer support plate 120 tilts, it compresses the air pump 310, causing the air pump 310 to compress. The gas in the air pump 310 is discharged through the exhaust pipe 320 to the explosion-proof airbag 330, causing the explosion-proof airbag 330 to expand and provide further buffer support for the movable plate 210.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
