Description

Technical Field

[0001] This application relates to the field of pedestrian access technology, and in particular to an underground pedestrian access system for separating human and machine personnel. Background Technology

[0002] Pedestrian walkways refer to the sections of a road that are separated by curbs, guardrails, or other similar facilities and are specifically for pedestrians. As an important component of urban roads, pedestrian walkways play a vital role in guiding urban traffic, creating urban landscapes, and utilizing underground space as cities develop rapidly.

[0003] In existing underground construction, the pedestrian passages on the left and right lines need to cross the transport marshalling yard. In order to balance the requirements of construction convenience, engineering quality and safety protection, a pedestrian passage system that crosses the track area is specially set up. This achieves physical isolation between operators and the track area during underground construction, ensures that personnel maintain a safe distance from the track when working, and avoids the safety risks brought about by transport marshalling operation from the perspective of spatial layout.

[0004] Regarding the aforementioned technologies, the inventors believe that existing underground pedestrian passages require disassembly and reassembly of the entire passage when adjusting its length according to working conditions. This process is cumbersome, time-consuming, and inconvenient for adjusting the length of the pedestrian passage, resulting in low efficiency in adjusting the passage length. Utility Model Content

[0005] The purpose of this application is to provide a downhole human-machine separation pedestrian passage to improve the problem of low efficiency in adjusting the passage length.

[0006] The technical solution for an underground man-machine separation pedestrian passage provided in this application is as follows:

[0007] A man-machine separation passageway in an underground well includes a passageway base plate and steps for ascending the passageway base plate. The top of the passageway base plate is provided with several guardrails, and the bottom of the passageway base plate is provided with several supports. The passageway base plate is provided with a detachable platform, and a positioning plate is provided at one end of the passageway base plate near the detachable platform. The positioning plate is provided with a sliding groove, and both ends of the detachable platform are provided with sliding blocks that can slide and engage with the sliding groove. The positioning plate is provided with several fixing pins, and the sliding blocks are provided with several fixing grooves for the fixing pins to insert and fix.

[0008] By adopting the above technical solution, a detachable platform that can slide along the bottom plate of the passage is set. By matching the fixing pin with the fixing groove on the detachable platform, the embedding depth of the sliding block in the sliding groove can be adjusted, thereby realizing convenient adjustment of the length of the pedestrian passage and improving the problem of low efficiency in adjusting the length of the passage.

[0009] Optionally, the fixing groove is provided with an elastic ring.

[0010] By adopting the above technical solution, the elastic ring that fits tightly with the fixing pin in the fixing groove makes the insertion and engagement of the fixing pin and the fixing groove more stable, thereby ensuring the stable engagement of the fixing pin and the fixing groove and reducing the occurrence of the fixing pin coming off.

[0011] Optionally, the fixing groove is provided with an inlay groove for the elastic ring to be embedded.

[0012] By adopting the above technical solution, the inlay groove for securing the elastic ring allows the elastic ring to be more stably fixed in the fixing groove, reducing the occurrence of the elastic ring detaching from the fixing groove due to changes in the fit between the fixing pin and the fixing groove.

[0013] Optionally, the fixed pin has a plug-in end near the elastic ring.

[0014] By adopting the above technical solution, after the fixing bolt is inserted into the fixing groove, the plug end squeezes the elastic ring until the plug end completely passes through the elastic ring. Then the plug end can abut against the elastic ring, so that the force required to pull the fixing pin out of the fixing groove is much greater than the force required to insert it, thereby ensuring that the connection between the fixing pin and the fixing groove is more stable.

[0015] Optionally, a pull ring is provided at the end of the fixing pin away from the plug end.

[0016] By adopting the above technical solution, it is more convenient to manually apply pulling force to the fixing pin when releasing the fixing pin from the fixing slot by pulling the pull ring. The fixing pin can be released from the fixing slot by pulling the pull ring.

[0017] Optionally, the detachable platform includes a stabilizing plate and a rotating plate rotatably connected to the stabilizing plate.

[0018] By adopting the above technical solution, the rotatable and foldable detachable platform makes it more convenient to store and move the detachable platform, reduces the space occupied after the detachable platform is disassembled, and reduces the difficulty of carrying the detachable platform.

[0019] Optionally, the stabilizing plate is provided with a locking plate at one end near the rotating plate, and the rotating plate is provided with a locking groove that can engage with the locking plate.

[0020] By adopting the above technical solution, the locking plate and locking groove are locked together, which restricts the rotation of the stable platform and the rotating platform. When the locking plate and locking groove are locked together, the rotational offset of the rotating plate and the stable plate is restricted, making the installation of the detachable platform and the channel base plate more stable.

[0021] Optionally, the locking plate is provided with fixing bolts that can be threadedly connected to the rotating plate.

[0022] By adopting the above technical solution, after the locking plate and locking groove are engaged, the locking plate and locking groove are reinforced by fixing bolts, and the connection between the stable plate and the rotating plate is fixed by the threaded connection of the bolts, thus ensuring the stable use of the detachable platform.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A detachable platform that can slide along the bottom plate of the passage is set up. By matching the fixing pin with the fixing groove on the detachable platform, the embedding depth of the sliding block in the sliding groove can be adjusted, thereby realizing the convenient adjustment of the length of the pedestrian passage and improving the problem of low efficiency in adjusting the length of the passage.

[0025] 2. After the fixing bolt is inserted into the fixing groove, the plug end squeezes the elastic ring until the plug end completely passes through the elastic ring. Then the plug end can abut against the elastic ring, so that the force required to pull the fixing pin out of the fixing groove is much greater than the force required to insert it, thereby ensuring that the connection between the fixing pin and the fixing groove is more stable.

[0026] 3. The rotatable and foldable detachable platform makes it more convenient to store and move, reduces the space occupied after the detachable platform is disassembled, and reduces the difficulty of carrying the detachable platform. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0033] A kind of underground human-machine separation pedestrian passage, referring to Figure 1 It includes a horizontal plate-shaped channel base 1 and steps 11 for climbing onto the channel base 1. Several guardrails 12 are fixedly installed on the top of the channel base 1 by bolt thread connection, and several supports 13 are fixedly installed on the bottom of the channel base 1 by bolt thread connection. In this embodiment, the number of guardrails 12 is preferably 2, and the guardrails 12 are rectangular plates. The number of supports 13 is preferably 6, and the supports 13 are round rods.

[0034] Reference Figure 1 The channel base plate 1 is provided with a horizontally plate-shaped detachable platform 2. The detachable platform 2 includes a stabilizing plate 21 and a rotating plate 22 rotatably connected to the stabilizing plate 21. In this embodiment, the end of the channel base plate 1 near the detachable platform 2 has a hole for storing the detachable platform 2. Both the stabilizing plate 21 and the rotating plate 22 are horizontally plate-shaped and are rotatably connected by a hinge. When the stabilizing plate 21 and the rotating plate 22 are rotated to keep them horizontal, the side walls of the stabilizing plate 21 and the rotating plate 22 abut against each other. After the two rotatable components are disassembled, the detachable platform is convenient for storage and carrying.

[0035] Reference Figure 1 and Figure 2 A rectangular positioning plate 3 is fixedly installed at one end of the channel base plate 1 near the detachable platform 2 by welding. A sliding groove 31 is provided on the inward side of the positioning plate 3. Sliding blocks 32 that can slide and cooperate with the sliding groove 31 are provided at both ends of the detachable platform 2 by welding. In this embodiment, the sliding block 32 is rectangular. When the detachable platform 2 is connected to the channel base plate 1, the detachable platform 2 is first aligned with the hole on the channel base plate 1, and then the channel base plate 1 and the detachable platform 2 are fixed by sliding cooperation.

[0036] Reference Figure 1 and Figure 2 The positioning plate 3 is provided with several fixing pins 33, and the sliding block 32 is provided with several fixing slots 34 for the fixing pins 33 to be inserted and fixed. In this embodiment, the number of fixing slots 33 is preferably 2, the material of the fixing pins 33 is preferably titanium alloy steel, and the number of fixing slots 34 is preferably 10. While the fixing pins 33 reinforce the channel base plate 1 and the detachable platform 2, the matching depth between the fixing pins 33 and the fixing slots 34 can be adjusted to facilitate the adjustment of the length of the channel base plate 1 and improve the problem of low efficiency in adjusting the length of the channel base plate 1.

[0037] Reference Figure 2 and Figure 3 The fixing groove 34 is provided with an elastic ring 35 and an inlay groove 36 for the elastic ring 35 to be embedded. In this embodiment, the material of the elastic ring 35 is preferably silicone rubber. The elastic ring 35 is circular, which makes the insertion and engagement of the fixing pin 33 and the fixing groove 34 more stable and reduces the occurrence of the fixing pin 33 coming off the fixing groove 34.

[0038] Reference Figure 2 and Figure 3 The fixed pin 33 is fixedly provided with a plug end 37 by welding at one end near the elastic ring 35. When the fixed pin 33 is inserted into the fixed groove 34, the end of the plug end 37 that abuts against the elastic ring 35 has a rounded corner, which makes it easy for the plug end 37 to pass through the elastic ring 35. This makes the force required to pull the fixed pin 33 out of the fixed groove 34 much greater than the force required to insert it, thereby ensuring a more stable connection between the fixed pin 33 and the fixed groove 34.

[0039] Reference Figure 2 and Figure 3 The end of the fixed pin 33 away from the insertion end 37 is fixedly provided with a ring-shaped pull ring 38 by welding. When the fixed pin 33 is released from the locking state of the fixed groove 34, the pull ring 38 can realize the labor-saving operation of manually pulling the fixed pin 33 by optimizing the force application structure, which significantly improves the convenience of force application.

[0040] Reference Figure 4 A horizontally shaped locking plate 23 is fixedly installed at one end of the stabilizing plate 21 near the rotating plate 22 by welding. The rotating plate 22 is provided with a locking groove 24 that can engage with the locking plate 23. The locking plate and the locking groove 24 are fitted together to limit the rotation of the stabilizing platform and the rotating platform. When the locking plate 23 and the locking groove 24 are engaged, the rotational offset of the rotating plate 22 and the stabilizing plate 21 is limited, making the installation of the detachable platform 2 and the channel base plate 1 more stable.

[0041] Reference Figure 4 The locking plate 23 is provided with fixing bolts 25 that can be threadedly connected to the rotating plate 22. The locking plate 23 and the locking groove 24 are reinforced by fixing bolts 25. The connection between the plate 21 and the rotating plate 22 is fixed and stabilized by the threaded connection of fixing bolts 25, ensuring the stable use of the detachable platform 2.

[0042] The implementation principle of this application embodiment is as follows:

[0043] When it is necessary to adjust the length of the pedestrian passage, the fixed pin 33 and the fixed groove 34 are selected and the detachable platform 2 is slid, so as to conveniently adjust the distance between the two ends of the detachable platform 2 and improve the problem of low efficiency in adjusting the length of the passage base plate 1.
