Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of isolation guardrails, in particular to a quick tunnel isolation guardrail with lighting devices. BACKGROUND

[0002] Tunnels are engineering buildings buried in mountains. With the continuous development of society, in order to facilitate people's travel and reduce travel distance, tunnels are often built in mountains to build highways for vehicle traffic. After the tunnel is built, the inside of the tunnel needs to be maintained regularly. During the maintenance process, part of the road needs to be occupied, and isolation guardrails need to be used. The main purpose of using guardrails for isolation is to ensure that pedestrians and vehicles do not enter the construction area by mistake. By defining the construction area, isolating traffic flow, and providing warnings, temporary guardrails ensure the safety of workers and the public. When using these guardrails, they should be installed before the start of construction and the position and layout should be determined according to the actual needs and construction plan to ensure that the connection between each guardrail is tight to ensure the stability of the entire guardrail system. In addition, the guardrails should be clearly marked and used with signs and warning lights to enhance the warning effect.

[0003] The existing patent No. CN219327387U discloses a tunnel maintenance isolation guardrail. The isolation guardrail is provided with a plurality of universal wheels at the bottom end of the guardrail plate, which makes it convenient to move the guardrail plate. The guardrail plate can be warned by setting guide stickers and reflective strips. However, the above-mentioned guardrail plate needs to be fixed by the staff one by one when fixed, and the contact area of the universal wheel with the ground is small, which makes the fixing effect of the guardrail plate poor when in use. Moreover, the above-mentioned guardrail plate does not have a fixing component, so when fixing two adjacent guardrail plates, a flexible rope needs to be used to connect and fix them one by one, which is cumbersome in actual use. In addition, the above-mentioned guardrail plate uses passive warning by setting guide stickers and reflective strips, while the two sides of the tunnel bottom are provided with lighting lamps for active warning. When the guardrail plate is isolated, one side of the lighting lamp is blocked, so the above-mentioned guardrail plate is not convenient for active warning when in use.

[0004] Therefore, the present application provides a quick tunnel isolation guardrail with lighting devices to eliminate the drawbacks of the existing devices. SUMMARY

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. Example 1

[0034] In one embodiment, such as Figures 1-13As shown, a quick-access tunnel barrier with a lighting device includes a barrier body 11. The bottom of the barrier body 11 has several casters. The bottom of the barrier body 11 is symmetrically equipped with mounting rods. Each mounting rod has an anti-slip plate 12 sleeved at one end. A first fixing plate is provided between two mounting rods. The first fixing plate has a fixing component for fixing the anti-slip plate 12. An installation tube 46 is fixedly installed on the barrier body 11. Rotating blocks 45 are symmetrically rotatable on the installation tube 46. Each rotating block 45 has a lighting lamp body 44 fixedly installed at its bottom end. The rotating block 45 has an adjusting component for adjusting the working angle of the lighting lamp body 44. A first side box 19 and a second side box 21 are fixedly installed on both sides of the barrier body 11. The first side box 19 and the second side box 21 each have internal components... A sliding block 24 is provided. Inside the first side box 19 and the second side box 21, a first latching box 20 and a second latching box 22 are respectively hinged to one side of the sliding block 24. Inside the first latching box 20 and the second latching box 22, a second contact block 51 and a first contact block 50 are respectively provided. Inside the first latching box 20 and the second latching box 22, a connecting mechanism is provided for fixing the two guardrail bodies 11 together. Inside the first side box 19 and the second side box 21, a retraction mechanism is provided for extending and retracting the sliding block 24. The connecting mechanism facilitates fixing the two adjacent guardrail bodies 11 together, and at the same time, the first contact block 50 and the second contact block 51 are tightly connected, thereby facilitating the power supply to the lighting body 44 for lighting. The retraction mechanism facilitates the quick storage and unfolding of the sliding block 24.

[0035] The fixing assembly includes a push rod 15, which is fixedly mounted on the upper end of the first fixing plate. One end of the push rod 15 extends to the outside of the guardrail body 11. A second return spring 14 is provided between one end of the mounting slide rod and the bottom end of the guardrail body 11. A first return spring 13 is provided between the upper end of the anti-slip plate 12 and the other end of the mounting slide rod. A fixing frame 16 is fixedly mounted on the bottom end of the first fixing plate. A first limiting frame 17 is provided below the fixing frame 16. A third return spring 18 is fixedly mounted on one side of the first limiting frame 17. A second fixing plate is provided on the other end of the third return spring 18. The second fixing plate is fixedly mounted on the bottom end of the guardrail body 11. The third fixing plate is fixed on the first limiting frame 17. The fixing plate is tightly attached to the bottom of the guardrail body 11. The third fixing plate has sliding groove rods on both sides, and the sliding groove rods are fixed to the bottom of the guardrail body 11. The first limiting frame 17 has a push plate fixed at one end. When it is necessary to fix the guardrail body 11, the user pushes the push rod 15. The push rod 15 drives the two anti-slip plates 12 to move through the first fixing plate. When the bottom of the anti-slip plate 12 is in close contact with the ground, the first limiting frame 17 fixes the fixing frame 16, thus fixing the anti-slip plate 12. When it is necessary to release the fixation of the guardrail body 11, the user pushes the first limiting frame 17 to slide through the push plate. Under the action of the second return spring 14, the anti-slip plate 12 moves away from the ground, thereby releasing the fixation of the guardrail body 11.

[0036] The adjustment assembly includes a stop ring 47. Both the mounting tube 46 and the mounting point of the rotating block 45 are fixedly provided with stop rings 47. The stop ring 47 has several stop grooves. A stop block 48 is tightly attached to the stop ring 47. Several stop strips are provided at the bottom of the stop block 48. A fifth return spring 49 is provided between the upper end of the stop block 48 and the interior of the rotating block 45. A pull rod is fixedly provided at the upper end of the stop block 48, and a handle is fixedly provided at one end of the pull rod. In use, when the lighting body 44 is needed for warning work or construction lighting, the handle can be pulled to move the stop block 48 away from the stop ring 47. Then, the lighting body 44 can be rotated to adjust the angle. After adjustment, the handle is released, and under the action of the fifth return spring 49, the stop block 48 and the stop ring 47 are tightly attached, thereby fixing the working position of the lighting body 44.

[0037] The connecting mechanism includes a second limiting frame 25 and a limiting strip 26. A first mounting groove and a second mounting groove are respectively provided at the same position on one side of the first snap-fit ​​box 20 and the second snap-fit ​​box 22. The second limiting frame 25 is disposed in the second mounting groove. A limiting strip 26, which cooperates with the second limiting frame 25, is provided in the first mounting groove. The bottom end of the second limiting frame 25 is fixedly connected to one end of several spring telescopic rods. All spring telescopic rods are fixedly disposed in the second mounting groove. A first torsion spring 23 is provided at the connection point between the sliding block 24 and the first snap-fit ​​box 20 and the second snap-fit ​​box 22. Abutment plates are symmetrically provided on one side of the first side box 19 and the second side box 21. The upper end of the second card box 22 is provided with a push-moving component for disconnecting the first card box 20 from the second card box 22. In use, when it is necessary to fix two adjacent guardrail bodies 11, the first side box 19 on one side of one guardrail body 11 is aligned with the second side box 21 on the other side of the guardrail body 11. Then, the contact plates on the first side box 19 and the second side box 21 are pressed together. The sliding blocks 24 inside the first side box 19 and the second side box 21 are moved by the retraction mechanism. When the first card box 20 and the second card box 22 are pressed together, the two guardrail bodies 11 are fixedly connected by the cooperation of the second limiting frame 25 and the limiting strip 26.

[0038] The pushing assembly includes a rotating push plate 27. The first and second snap-fit ​​boxes 20 and 22 are respectively provided with a third mounting groove and a fourth mounting groove at their upper ends. The rotating push plate 27 is rotatably mounted within the fourth mounting groove. A fourth torsion spring is provided at the connection points between the rotating shafts at both ends of the rotating push plate 27 and the second snap-fit ​​box 22. A fourth fixing plate is tightly attached to the upper end of the rotating push plate 27 and is fixedly mounted on one side of the fourth mounting groove. A first magnet 28 is fixedly mounted on the upper end of the rotating push plate 27, and a second magnet 29 is fixedly mounted on one side of the fourth fixing plate. A fixing handle is fixedly mounted on the upper end of the rotating push plate 27. In use, when it is necessary to disconnect the connection between the first snap-fit ​​box 20 and the second snap-fit ​​box 22... When the rotating push plate 27 is rotated by pulling the fixed handle, one end of the rotating push plate 27 pushes the second limiting frame 25 to slide in the second mounting groove, so that the second limiting frame 25 disengages from the limiting strip 26, thereby releasing the connection between the first snap-fit ​​box 20 and the second snap-fit ​​box 22. Subsequently, the first magnet 28 and the second magnet 29 are pressed together, thereby fixing the rotating push plate 27. When the retracting mechanism retracts the second snap-fit ​​box 22 into the second side box 21, during the storage process, one side of the rotating push plate 27 is pressed together with one side of the second side box 21, so that the first magnet 28 and the second magnet 29 are separated. Under the action of the fourth torsion spring, the rotating push plate 27 rotates to the initial position.

[0039] A transfer controller 52 is provided on one side of the outermost guardrail body 11. The transfer controller 52 is located on one side of the first side box 19. A second snap-fit ​​box 22 is fixedly provided on one side of the transfer controller 52. The output end of the transfer controller 52 is electrically connected to the first contact block 50. A wire is provided inside the guardrail body 11. The wire is electrically connected to the first contact block 50, the second contact block 51, and the lighting lamp body 44. A socket plate is fixedly provided at the bottom of the transfer controller 52. The socket plate is sleeved with an abutment plate on one side of the first side box 19. An indicator plate 53 is fixedly provided on one side of the guardrail body 11. In use, when it is necessary to... When the lighting body 44 is powered on, the adapter controller 52 is fixed by the socket plate and the contact plate on one side of the first side box 19. Then, the first contact block 50 on one side of the adapter controller 52 is electrically connected to the second contact block 51 on one side of the first side box 19 by the cooperation of the second limit bracket 25 and the limit strip 26. Then, the input terminal of the adapter controller 52 is electrically connected to the external power supply. Several guardrail bodies 11 are electrically connected by the first contact block 50, the second contact block 51 and the wire, so that several lighting bodies 44 can provide illumination. It is worth noting that the adapter controller 52 in this application is an existing component.

[0040] The retracting mechanism includes a spiral groove rod 36, with a ratchet 32 ​​rotatably mounted at one end of the spiral groove rod 36. The ratchet 32 ​​is rotatably mounted inside the first side box 19 and the second side box 21. The ratchet 32 ​​has a plurality of ratchet teeth on its inner side. A stop pawl 33 is rotatably mounted at one end of the spiral groove rod 36 corresponding to the position inside the ratchet 32. A second torsion spring 34 is provided at the connection between the stop pawl 33 and the spiral groove rod 36. A stop plate 35 is fixedly mounted at one end of the spiral groove rod 36 and at one side of the stop pawl 33. The ratchet 32 ​​has a fixed post 31 at its bottom end, and a limiting groove rod 30 is slidably provided on the fixed post 31. The limiting groove rod 30 is fixedly connected to the upper end of the sliding block 24. First guide groove rods are slidably provided at both ends of the limiting groove rod 30. The first guide groove rods are fixedly provided inside the first side box 19 and the second side box 21. The spiral groove rod 36 has a spiral groove, and a sliding post 37 is slidably provided inside the spiral groove. The sliding post 37 is fixedly provided at one end inside the sliding sleeve 38. Limiting slide rods are fixedly provided on both sides of the cylinder 38. Guide slide grooves are provided inside the first side box 19 and the second side box 21 at positions corresponding to the limiting slide rods. A first retaining plate 40 is fixedly provided at one end of the spiral groove rod 36. A fourth return spring 39 is provided between the upper end of the first retaining plate 40 and one end inside the sliding sleeve 38. In use, when it is necessary to unfold or retract the sliding block 24, the user pushes the sliding sleeve 38. When the sliding column 37 engages with the spiral groove on the spiral groove rod 36, the spiral groove rod... 36 drives the ratchet 32 ​​to rotate the third return spring 180 degrees. The ratchet 32 ​​works with the limiting groove rod 30 through the fixed post 31, so that the sliding block 24 can be unfolded or retracted. Then the sliding sleeve 38 is released. Under the action of the fourth return spring 39, the sliding sleeve 38 returns to the initial position. Since the helical groove rod 36 is only fixed with a stop plate 35 at the position of the stop pawl 33, when the sliding sleeve 38 returns to the initial position, the rotation of the helical groove rod 36 will not drive the ratchet 32 ​​to rotate.

[0041] A fixing tube is fixedly provided at the upper end of the ratchet 32, and a second clamping plate 41 is fixedly provided at one end of the fixing tube. Both the first clamping plate 40 and the second clamping plate 41 are symmetrically provided with limiting holes. A first stop post is slidably provided in each of the two limiting holes at the bottom end of the second clamping plate 41. The two first stop posts are respectively fixed at one end of two connecting brackets. The two connecting brackets are respectively fixed at the bottom end of the sliding sleeve 38. A second stop post is slidably provided in the limiting hole at the bottom end of the first clamping plate 40. The second stop post is fixedly provided at one end of a connecting plate. The connecting plate is fixedly provided inside the sliding sleeve 38. A rotating handle 42 is rotatably provided at the upper end of the sliding sleeve 38. A third torsion spring 43 is provided at the connection with the sliding sleeve 38. When it is necessary to push the sliding sleeve 38 to move, the rotating handle 42 needs to be rotated so that the two ends of the rotating handle 42 are aligned with the guide groove. At the same time, before the sliding post 37 contacts the spiral groove on the spiral groove rod 36, the first stop post and the second stop post disengage from the second clamping plate 41 and the first clamping plate 40. When the sliding sleeve 38 returns to the initial position, the first stop post and the second stop post cooperate with the second clamping plate 41 and the first clamping plate 40 to prevent the sliding block 24 from driving the ratchet 32 ​​to rotate during use. At the same time, rotating the handle 42 can prevent the sliding sleeve 38 from being accidentally touched when not in use. Example 2

[0042] The difference from Embodiment 1 is that: a protective plate is provided on one side of the first side box 19 and the second side box 21 corresponding to the position of the sliding block 24. A second guide groove rod is slidably provided on both sides of the protective plate. The second guide groove rod is fixedly provided on one side of the first side box 19 and the second side box 21. A third magnet is fixedly provided at both ends of the second guide groove rod. A fourth magnet is provided at both ends of the protective plate. When in use, when the guardrail body 11 is not in use, the protective plate can protect the opening end of one side of the first side box 19 and the second side box 21, thereby protecting the first contact block 50 and the second contact block 51.

[0043] The above embodiments disclose a quick-access tunnel isolation barrier with a lighting device. When using the barrier body 11 for isolation, the barrier body 11 is moved to the work site using casters. Then, the first side box 19 on one side of one barrier body 11 is aligned with the second side box 21 on the other side of the barrier body 11. The contact plates on the first side box 19 and the second side box 21 are then pressed tightly together. The user pushes the push rod 15, which moves two anti-slip plates 12 via the first fixing plate. When the bottom of the anti-slip plates 12 is pressed tightly against the ground, the first limiting frame 17 fixes the fixing frame 16, thus fixing the barrier body 11. The user pushes the sliding sleeve 38, and when the sliding post 37 engages with the spiral groove on the spiral groove rod 36, the spiral groove rod 36 drives the ratchet 32 ​​to rotate the third return spring 180 degrees. The ratchet 32 ​​is connected to the limiting groove rod via the fixing post 31. When used in conjunction with the 30, the sliding block 24 unfolds, and then the sliding sleeve 38 is released.
