Description

Technical Field

[0001] This invention relates to the field of highway movable guardrail technology, specifically to a deflectable telescopic opening movable guardrail. Background Technology

[0002] Opening movable barriers are common safety facilities in road management. They are installed at openings in the median strip and connecting passages to facilitate emergency vehicles (such as accident response vehicles and ambulances) to travel in the opposite lane in emergencies. They can also be temporarily opened when one side of the road is closed for construction, allowing vehicles to temporarily enter the opposite lane. They provide a certain degree of isolation and protection. Currently, commonly used movable barriers include prestressed movable barriers, frame movable barriers, ladder-type movable barriers, and combined movable barriers. However, most of these barriers lack crashworthiness, and those that do have crashworthiness are inconvenient to move and expensive. Furthermore, they do not guide oncoming traffic when yielding to emergency vehicles, easily leading to traffic accidents. In addition, because the length of median strip openings varies from place to place, traditional barriers need to be designed to suit local conditions, resulting in long construction periods and low efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects in the existing technology and provide a deflectable telescopic opening movable guardrail that has strong anti-collision capability, is easy to disassemble and move quickly in emergency situations, and can also guide vehicles to change lanes when it occupies the opposite lane.

[0004] To achieve the above objectives, the technical solution provided by this invention is: a deflectable telescopic opening movable guardrail, comprising: connecting components, threaded posts, anti-collision bars, rotating devices, reflectors, pins, fixing components, and a rubber protective layer. The anti-collision bars are installed between two adjacent connecting components. The threaded posts are disposed in the connecting channels inside the connecting components. The rotating devices can mesh with the threads of the threaded posts through gears. The reflectors are disposed on the top of the threaded posts. The pins can control the rotation of the rotating devices through insertion holes.

[0005] The connecting component includes a support structure, a connecting channel, a sliding groove, a socket, and a fixing member. The lower part of the support structure is provided with several universal wheels. The upper part of the sliding groove is provided with a sliding slot, and the other end is provided with a fan-shaped groove. The width of the sliding groove is greater than that of the sliding slot but smaller than that of the fan-shaped groove. The fixing member is provided with a bullet shape, located on the upper and lower sides of the fan-shaped groove, and has a bolt hole B in the middle. The bolt hole B can be connected to the bolt hole A by a bolt.

[0006] The threaded column has threads at the top and smooth at the bottom. The top can be connected to a reflector, and the bottom can be inserted into a positioning hole reserved in the ground. The reflector serves to warn vehicles of the location of this device.

[0007] The anti-collision bar includes a locking post, a rotating section, a connecting section, and an anti-collision section. The locking post includes a post body and a post cap. The lower part of the post body is provided with a threaded section. The rotating section has the same thickness as the anti-collision section but is slightly narrower in width. The end is provided in the form of a sleeve. The inside of the sleeve is smooth and the diameter is slightly larger than that of the threaded section. The connecting section is a transition section between the rotating section and the anti-collision section. The anti-collision section is provided with a limit locking post in the middle and a bolt hole A at the end.

[0008] The rotating device includes a gear, a turntable, a bearing, and a pin hole. The gear can mesh with the thread of the threaded column, and the diameter of the pin hole is slightly larger than the diameter of the pin.

[0009] The rubber protective layer is disposed inside the connecting channel, sliding groove, sliding slot and fan-shaped groove to reduce wear on the device.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The present invention provides a deflectable telescopic opening movable guardrail. The rotating section of the anti-collision bar has the same thickness as the anti-collision section but is slightly narrower in width.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1:

[0026] See Figures 1 to 8 A deflecting telescopic anti-collision opening movable guardrail includes: a connecting component 1, a threaded post 2, an anti-collision bar 3, a rotating device 4, a reflector 5, a pin 6, a fixing component 16, and a rubber protective layer 8. The anti-collision bar 3 is installed between two adjacent connecting components 1. The threaded post 2 is disposed in the connecting channel 13 inside the connecting component 1. The rotating device 4 can mesh with the thread of the threaded post 2 through a gear 41. The reflector 5 is disposed on the top of the threaded post 2. The pin 6 can control the rotation of the rotating device 4 through a hole 19.

[0027] The connecting component 1 includes a support structure 11, a connecting channel 13, a sliding groove 15, a socket 19, and a fixing member 16. The lower part of the support structure 11 is provided with several universal wheels 12. The upper part of the sliding groove 15 is provided with a sliding slot 14, and the other end is provided with a fan-shaped groove 18. The width of the sliding groove 15 is greater than that of the sliding slot 14 but smaller than that of the fan-shaped groove 15. The fixing member 16 is provided with a bullet shape and is located on the upper and lower sides of the fan-shaped groove 18. The middle part is a bolt hole B17. The bolt hole B17 can be connected to the bolt hole A36 by a bolt 7.

[0028] The threaded column 2 has threads at the upper end and smooth at the lower end. The top end can be connected to the reflector 5, and the bottom end can be inserted into the positioning hole reserved in the ground. The reflector 5 serves to warn vehicles of the location of this device.

[0029] The anti-collision bar includes a locking post 31, a rotating section 33, a connecting section 34, and an anti-collision section 35. The locking post 31 includes a post body 311 and a post cap 312. The lower part of the post body 311 is provided with a threaded section. The rotating section 33 has the same thickness as the anti-collision section 35 but is slightly narrower in width. The end is provided in the form of a sleeve. The inside of the sleeve is smooth and the diameter is slightly larger than that of the threaded section. The connecting section 34 is a transition section between the rotating section 33 and the anti-collision section 35. The anti-collision section is provided with a limit locking post 32 in the middle and a bolt hole A36 at the end.

[0030] The rotating device includes a gear 41, a turntable 42, a bearing 43, and a pin hole 44. The gear 41 can mesh with the thread of the threaded column 2, and the diameter of the pin hole 44 is slightly larger than the diameter of the pin 6.

[0031] The rubber protective layer 8 is disposed inside the connecting channel 13, the sliding groove 15, the sliding slot 14 and the fan-shaped groove 18 to reduce wear on the device.

[0032] In this embodiment, during on-site installation, the present invention can be pre-assembled in sections at the factory and then transported. Each connecting component 1 and its connected anti-collision bars 3 constitute a working section. Upon arrival at the construction site, the connecting channel 13 of the connecting component 1 of the first working section is first aligned with the positioning hole reserved on the ground. Then, the threaded column 2 is lowered using the rotating device 4 and inserted into the positioning hole. Next, the locking post 31 of the anti-collision bar 3 of the second working section is disassembled and the anti-collision bar 3 is connected to the sliding groove 15 reserved in the first working section. At this time, the anti-collision section 35 is located inside the sliding groove 15, and adjacent connecting components 1 cannot rotate relative to each other. Then, the locking post 31 is reinstalled, the connecting channel 13 of the second working section is aligned with the positioning hole, and the threaded column 2 is lowered. This process is repeated until the installation is completed.

[0033] Example 2:

[0034] When this invention is used as a guardrail on ordinary highways, if there is an emergency and the road needs to be opened for special vehicles in the shortest possible time, the threaded column 2 can be raised from the ground positioning hole by rotating the device 4 in sequence, and then the device can be pushed from one end until the limit locking column 32 contacts the fixing member 16. At this time, a certain distance can be maintained between each connecting member 1, and the device can be quickly retracted.

[0035] Example 3:

[0036] When a road becomes impassable due to a traffic accident and the opposite lane needs to be used for temporary passage, the threaded post 2 can be raised from the ground positioning hole by rotating the device 4 in sequence. Then, the device can be pulled from one end until the locking post 31 slides into the sliding groove 14. At this time, since the rotating section 33 of the anti-collision bar 3 is narrower than the anti-collision section 35, the locking post 31 is located at the connection between the sliding groove 15 and the fan-shaped groove 18, so that the anti-collision bar 3 can rotate a certain angle in the fan-shaped groove 18. Therefore, the device can be manually extended to the opposite lane. At the same time, a similar operation can be performed on the device at the next opening of the central divider to guide vehicles. Finally, the device can be transformed into a movable guardrail with the function of guiding vehicles to change lanes.

[0037] It should be noted that when operating this device, all personnel must strictly abide by traffic regulations. Roadblocks should be placed between the device that guides vehicles into the opposite lane and the device that guides vehicles back to their original lane, and warning signs should be placed in advance in the occupied lane as required.
