Description

Technical Field

[0001] The utility model relates to the technical field of walking boards, in particular to a rubber walking board used for railway bridges or tunnels. Background Art

[0002] Railway bridges are structures built to allow railways to cross rivers, lakes, straits, valleys, or other obstacles, or to create grade separations between railway lines or roads. Pedestrian walkways are a crucial component of railway bridges, and the sidewalks on these walkways are crucial for the safe passage of bicycles and pedestrians. Damage to these walkways can directly impact public safety. In recent years, many railway bridges in China have experienced varying degrees of excessive lateral amplitude damage in their steel beams, seriously endangering traffic safety. To reduce the weight of bridges and minimize the maintenance workload for bridge maintenance departments, existing sidewalks are typically made primarily of rubber.

[0003] The patent document with announcement number CN215561926U discloses a railway bridge sidewalk walking board device, comprising a first placement groove, an installation cross plate, a support plate body mechanism and an anti-slip strip. First, the second frame is placed at the position to be installed on the bridge, and then the first frame is fixed to the bridge by a first bolt, and then the support plate body mechanism is placed on the inner side of the second frame at the top of the first frame by screwing the two handles, and the four support plate body mechanisms are placed on the inner side of the second frame in sequence, and then the third bolt is turned to make the bottom end thereof threadedly connected with the top of the first frame, and then the four support plate body mechanisms are fixed to the first frame to realize the installation of the walking board device. The anti-slip performance of the walking board is improved by the setting of the anti-slip strip. When the support plate body mechanism is damaged and needs to be replaced, the third bolt is turned to disengage it from the first frame, and then the base plate is taken out from the inner side of the second frame by holding the handle. However, the prior art still has defects:

[0004] (1) In the prior art, when installing the walking board, it is necessary to turn the four third bolts in sequence and repeatedly tighten them so that the bottom ends thereof are threadedly connected with the top of the first frame. The process is relatively cumbersome and inconvenient for the quick installation of the walking board. It is not only time-consuming and labor-intensive, but also when the walking board is used outdoors, especially on rainy days, the environment is relatively humid. After long-term use, the bolts are prone to rust and cannot be used normally, thereby affecting the subsequent disassembly and replacement installation, and the practicality is low.

[0005] (2) The existing walking boards are not convenient for draining the accumulated water on the upper surface of the walking boards during use. When pedestrians walk on the walking boards, water stains are easily splashed in the gaps between the multiple walking boards, causing discomfort to pedestrians during walking, affecting the pedestrian's traffic efficiency, and having low practicality.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 6 As shown, this embodiment provides a rubber walking board for railway bridges or tunnels, comprising a mounting frame 1 , a rectangular notch 11 being provided on the top of the mounting frame 1 , and a plurality of rubber walking boards 2 being provided on the top of the mounting frame 1 .

[0030] A fixing structure 3 is provided at both ends of the mounting frame 1. The fixing structure 3 includes a receiving groove 31 opened on the inner wall of the rectangular notch 11. A fixing groove 32 is opened at both ends of the rubber walking board 2. The fixing groove 32 corresponds to the position of the receiving groove 31. A fixing rod 33 is inserted into the storage groove 31. One end of the fixing rod 33 is fixedly connected to a pull ring plate 34. The other end of the fixing rod 33 is clamped in the fixing groove 32. A pressure plate 35 is fixedly connected to the fixing rod 33. The pressure plate 35 is slidably connected to the inside of the storage groove 31. A spring 36 is provided on the outside of the fixing rod 33. The spring 36 is provided at a position where the pressure plate 35 and the storage groove 31 are away from the fixing groove 32. When the rubber walking board 2 is installed, the pull ring plate 34 is pulled to move the fixing rod 33 so that the end of the fixing rod 33 disengages from the fixing groove 32 and retracts into the inside of the receiving groove 31. At this time, the fixing rod 33 drives the pressure plate 35 to move and squeezes the spring 36. By aligning the fixing groove 32 on the outer surface of the rubber walking board 2 with the fixing rod 33, the pull ring plate 34 is released. Under the elastic action of the spring 36, the pressure plate 35 and the fixing rod 33 are driven to move, so that the end of the fixing rod 33 is snapped into the fixing groove 32, thereby fixing the rubber walking board 2 in the rectangular notch 11 at the top of the installation frame 1.

[0031] The top of the rubber walking board 2 is provided with an anti-sliding block 4. There are several anti-sliding blocks 4 arranged at equal intervals. By arranging the anti-sliding blocks 4 on the surface of the walking board, it is both beautiful and has an anti-slip effect. Pedestrians can pass safely and smoothly without bumps, effectively preventing accidents and improving safety during construction work in rainy weather.

[0032] A drainage structure 5 is provided on the top of the mounting frame 1. The drainage structure 5 includes a guide groove 51 opened at the top of the inner wall of the rectangular notch 11. Drainage grooves 52 are opened at both ends of the inner wall of the guide groove 51. There are multiple groups of drainage grooves 52 and they are arranged at an angle downward. One end of the drainage groove 52 extends to the outside of the mounting frame 1. A guide hole 53 is opened in the middle of the top of the rubber walking board 2. The guide hole 53 is a structure that is wide at the top and narrow at the bottom. The guide hole 53 is arranged above the guide groove 51. Through the arrangement of the guide hole 53, the accumulated water on the upper surface of the rubber walking board 2 can be diverted downward to the guide groove 51 for collection. The accumulated water inside the guide groove 51 can be diverted and discharged through the drainage grooves 52 at both ends, which can prevent water from accumulating on the upper surface of the rubber walking board 2.

[0033] A plurality of mounting grooves 6 are provided at both ends of the top of the rectangular notch 11, and a fixing bolt 7 is threadedly connected to the bottom of the inner wall of the mounting groove 6. The bottom end of the fixing bolt 7 passes through the bottom of the mounting frame 1 and the end extends to the outside. A mounting hole is drilled on the bridge deck of the railway bridge, and the fixing bolt 7 is rotated so that the bottom end of the fixing bolt 7 passes through the mounting frame 1 and is inserted into the inside of the mounting hole, which can limit the mounting frame 1, thereby ensuring the stability of the installation of the walking board.

[0034] When the present invention is implemented, the installation frame 1 is first placed at the position to be installed on the railway bridge, and then the fixing bolts 7 are rotated to fix the installation frame 1 to the railway bridge. Then, the pull ring plate 34 is pulled to drive the fixing rod 33 to move, so that the end of the fixing rod 33 is disengaged from the fixing groove 32 and retracted into the inside of the receiving groove 31. At this time, the fixing rod 33 drives the pressure plate 35 to move and squeeze the spring 36. Then, the fixing groove 32 on the outer surface of the rubber walking board 2 is aligned with the fixing rod 33, and the pull ring plate 34 is released. Under the elastic action of the spring 36, the pressure plate 35 and the fixing rod 33 are driven to move, so that the end of the fixing rod 33 is clamped into the fixing groove 32, so that the rubber walking board 2 can be fixed to the rectangular notch at the top of the installation frame 1. 11, the installation of the rubber walking board 2 is realized. When the damaged rubber walking board 2 needs to be replaced, the pull ring plate 34 is pulled to drive the fixing rod 33 to disengage from the fixing groove 32, and the damaged rubber walking board 2 can be removed for replacement and maintenance. It is safe, firm, and easy to dismantle without causing damage to the bridge structure. When water accumulates on the upper surface of the rubber walking board 2, the accumulated water can be guided downward through the guide holes 53 to the guide groove 51 for collection. The accumulated water inside the guide groove 51 can be guided and discharged through the drainage grooves 52 at both ends, which can avoid the accumulation of water on the upper surface of the rubber walking board 2, so that pedestrians will not splash water when walking on the rubber walking board 2, thereby improving the pedestrian traffic efficiency and thus improving the practicality of the rubber walking board.
