Description

Technical Field

[0001] This application relates to the field of traffic facilities, and specifically to a movable guardrail for tidal lanes. Background Art

[0002] At present, with the increase in urban road traffic flow, tidal lanes have become one of the important measures to relieve traffic congestion during peak hours. Tidal lanes achieve reasonable allocation of road resources and improve traffic efficiency by dynamically adjusting the driving direction. However, the existing tidal lane guardrails usually adopt manual handling or rely on large mechanical equipment to assist in moving during adjustment. This method has problems such as complex operation, time-consuming and laborious, and poor stability. Especially in emergency situations, it is impossible to quickly and flexibly adjust the lane allocation and it is difficult to adapt to the rapid changes during the peak period of road traffic. Summary of the Invention

[0003] This application provides a movable guardrail for tidal lanes to solve the problems of complex operation, time-consuming and laborious, and poor stability existing in the prior art.

[0004] The movable guardrail for tidal lanes provided by this application includes a guardrail body and a guide rail;

[0005] The guide rail extends linearly along the width direction of the tidal lane and is embedded in the ground;

[0006] The guardrail body includes a plurality of columns spaced apart along the horizontal direction perpendicular to the guide rail. The bottom of the column at the first end has a guide rail roller that can roll on the guide rail, so that the column at the first end can only move along the length direction of the guide rail. The bottoms of the columns at the tail end and all intermediate columns have universal rollers that can roll on the ground;

[0007] Any two adjacent columns are connected by a telescopic component, so that any two adjacent columns can approach or move away from each other along the horizontal direction perpendicular to the guide rail;

[0008] Guide holes are provided through the columns at the first end and all intermediate columns along the horizontal direction perpendicular to the guide rail. A guide rod is provided on the column at the end. The first end of the guide rod is fixed to the column at the end, and the second end of the guide rod faces the guide holes on the intermediate columns. The guide rod is coaxially arranged with the guide holes on the column at the first end and all intermediate columns;

[0009] When the guardrail body is completely retracted to the minimum state, the guide rod passes through the guide holes on all intermediate columns and extends into the guide hole on the column at the first end.

[0010] Preferably, one end of all the guide holes facing the guide rod is open.

[0011] Preferably, bushings are provided on the inner walls of all the guide holes to reduce the frictional resistance when the guide rods pass through.

[0012] Preferably, a movable rod is provided on the upright column at the first end. The movable rod vertically penetrates the upright column at the first end and can move up and down. An inclined surface guide hole facing the guide rod is provided on the movable rod;

[0013] A compression spring is also sleeved on the movable rod. The compression spring is located below the upright column at the first end. The upper end of the compression spring is joined to the bottom of the upright column at the first end, and the lower end of the compression spring is joined to the movable rod;

[0014] Two positioning holes are provided on the ground. The two positioning holes are spaced apart along the width direction of the tidal lane. The two positioning holes are respectively located on the left and right lane lines of the tidal lane, and the two positioning holes are close to the guide rail;

[0015] When the guardrail body moves to both ends of the guide rail, the movable rods are respectively aligned with the two positioning holes. At this time, if the guardrail body is retracted so that the guide rod enters the guide hole on the upright column at the first end, the guide rod can act on the inclined surface of the inclined surface guide hole to move the movable rod upward and out of the positioning hole. At this time, the compression spring is compressed; at this time, if the guardrail body is unfolded so that the guide rod disengages from the guide hole on the upright column at the first end, the movable rod can be driven by the compression spring to move downward to insert into the lower positioning hole.

[0016] Preferably, a end cap is provided at the upper end of the movable rod. The end cap is located above the upright column at the first end. When the movable rod is driven by the compression spring to move downward to insert into the lower positioning hole, the end cap abuts against the top surface of the upright column at the first end.

[0017] Preferably, a magnet is provided on the upright column at the first end. The magnet covers one end of the guide hole facing away from the guide rod. The guide rod is made of a magnetic metal material. When the guardrail body is fully retracted to the minimum state, the end face of the second end of the guide rod is attracted to the magnet.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is made with reference to the accompanying drawings.

[0026] As Figure 1 , Figure 2 shown, the mobile guardrail for a tidal lane in this embodiment includes a guardrail body 100 and a guide rail 200.

[0027] The guide rail 200 extends linearly along the width direction of the tidal lane 230 and is embedded in the ground 210. That is to say, there is a groove 212 on the ground 210, and the groove 212 extends along the width direction of the tidal lane 230. The two ends of the groove 212 are located on the left and right lane lines of the tidal lane 230, and the guide rail 200 is arranged in the groove 212, and the top of the guide rail 200 is basically flush with the ground 210.

[0028] The guardrail body 100 includes a plurality of upright columns 10 spaced apart in the horizontal direction perpendicular to the guide rail 200. Each upright column 10 is vertically arranged. The bottom of the first upright column 10 has a guide rail roller 11, and the guide rail roller 11 can roll on the guide rail 200, so that the first upright column 10 can only move along the length direction of the guide rail 200, thereby ensuring that the moving track is accurate when the guardrail body 100 moves along the width direction of the tidal lane 230. The bottoms of the last upright column 10 and all intermediate upright columns 10 have universal rollers 12 that can roll on the ground 210. The universal rollers 12 can rotate flexibly, so that the last upright column 10 and all intermediate upright columns 10 can move not only along the width direction of the tidal lane 230 but also along the driving direction of the tidal lane 230, enabling the guardrail body 100 to be smoothly retracted and extended.

[0029] Any two adjacent upright columns 10 are connected by a telescopic component, so that any two adjacent upright columns 10 can approach or move away from each other in the horizontal direction perpendicular to the guide rail 200. The telescopic component is a scissor link mechanism 20. The two sides of the scissor link mechanism 20 are respectively connected to two adjacent upright columns 10. The two connecting ends on each side of the scissor link mechanism 20 are respectively hinged to a fixed seat 192 and a sliding seat 191 on the connected upright column 10. The fixed seat 192 is fixedly arranged on the upright column 10, and the sliding seat 191 is slidably arranged in the chute 18 of the upright column 10. The chute 18 is opened on the side wall of the upright column 10 and extends vertically up and down. The cross section of the chute 18 is a dovetail shape, and the shape of the sliding seat 191 is adapted to the chute 18, so that the sliding seat 191 can only slide up and down along the chute 18 and cannot fall out of the chute 18. In this way, when the scissor link mechanism 20 undergoes telescopic deformation, the sliding seat 191 can slide up and down along the chute 18 where it is located, so as to realize the rapid telescopic adjustment of the guardrail body 100, enabling the guardrail body 100 to be shortened from dozens of meters to 3 - 5 meters.

[0030] The first upright column 10 and the last upright column 10 are each provided with only one sliding seat 191 and one fixed seat 192. One sliding seat 191 and one fixed seat 192 are provided on the left and right side surfaces of all intermediate upright columns 10.

[0031] On the first upright post 10 at the head end and all the intermediate upright posts 10, there are through guide holes 13 arranged in a horizontal direction perpendicular to the guide rail 200. On the last upright post 10, there is a guide rod 14. The first end of the guide rod 14 is fixedly connected to the last upright post 10, and the second end of the guide rod 14 is a free end. The second end of the guide rod 14 faces the guide hole 13 on the intermediate upright post 10. The guide rod 14 and the guide holes 13 on the first upright post 10 and all the intermediate upright posts 10 are coaxially arranged to ensure that when the guardrail body 100 is retracted, the guide rod 14 can smoothly pass through the guide holes 13 on all the intermediate upright posts 10 and extend into the guide hole 13 on the first upright post 10, forming a guiding and limiting effect, realizing the stable movement direction of each component when the guardrail body 100 expands and contracts, ensuring the stable structure of the guardrail body 100 after retraction, and improving the impact resistance performance.

[0032] When the guardrail body 100 is completely retracted to the minimum state, the guide rod 14 passes through the guide holes 13 on all the intermediate upright posts 10 and extends into the guide hole 13 on the first upright post 10. At this time, the guardrail body 100 can move along the guide rail 200 to change the driving direction of the tidal lane.

[0033] One end of all the guide holes 13 facing the guide rod 14 is open, so that the open end of the guide hole 13 has a guiding effect, enabling the guide rod 14 to easily enter each guide hole 13 when the guardrail body 100 is retracted.

[0034] On the inner walls of all the guide holes 13, there are bushings provided to reduce the frictional resistance when the guide rod 14 passes through, reduce the frictional loss of the guide rod 14, extend the service life, and reduce the maintenance cost.

[0035] On the first upright post 10, there is a movable rod 15. The movable rod 15 vertically penetrates the first upright post 10 and can move up and down. On the movable rod 15, there is an inclined plane guide hole 151 facing the guide rod 14. The upper side of the inclined plane guide hole 151 is an inclined plane. The inclined plane guide hole 151 is communicated with the guide hole 13 and faces the guide rod 14.

[0036] A compression spring 16 is also sleeved on the movable rod 15. The compression spring 16 is located below the first upright post 10. A circular protrusion 153 is arranged at the lower part of the movable rod 15. The upper end of the compression spring 16 abuts against the bottom of the first upright post 10, and the lower end of the compression spring 16 abuts against the circular protrusion 153.

[0037] On the ground 210, there are two positioning holes 211 arranged at intervals along the width direction of the tidal lane. The two positioning holes 211 are respectively located on the left and right lane lines of the tidal lane, and the two positioning holes 211 are close to the guide rail 200.

[0038] When the guardrail body 100 moves to both ends of the guide rail 200, the movable rods 15 are respectively aligned with the two positioning holes 211. At this time, if the guardrail body 100 is folded so that the guide rod 14 enters the guide hole 13 on the first column 10, the guide rod 14 can act on the inclined surface of the inclined surface guide hole 151, so that the movable rod 15 moves upward and disengages from the positioning hole 211. At this time, the compression spring 16 is compressed, and at this time the guardrail body 100 can move along the guide rail 200; at this time, if the guardrail body 100 is unfolded so that the guide rod 14 disengages from the guide hole 13 on the first column 10, the movable rod 15 can be driven by the compression spring 16 to move downward and insert into the lower positioning hole 211. At this time, the guardrail body 100 is limited and cannot move.

[0039] A end cap 152 is provided at the upper end of the movable rod 15. The end cap 152 is located above the first column 10. The end cap 152 is integrally formed with the column 100. When the movable rod 15 is driven by the compression spring 16 to move downward and insert into the lower positioning hole 211, the end cap 152 abuts against the top surface of the first column 10 to prevent the movable rod 15 from moving downward excessively or disengaging, further improving the stability of the guardrail body 100 during telescoping.

[0040] A magnet 17 is provided on the first column 10. The magnet 17 covers one end of the guide hole 13 facing away from the guide rod 14. The guide rod 14 is made of a magnetic metal material. When the guardrail body 100 is completely folded to the minimum state, the end face of the second end of the guide rod 14 is attracted to the magnet 17 to improve the stability of the guide rod 14 and prevent the guardrail body 100 from unnecessary extension due to shaking when moving along the guide rail, improving the service performance of the movable guardrail.

[0041] Refer to Figure 2, the southbound lane 220 is for vehicles to travel from north to south, the northbound lane 240 is for vehicles to travel from south to north, and the driving direction of the tidal lane 230 can be changed according to the time period or traffic flow conditions. For example, during the time period when there are more vehicles traveling from south to north, the guardrail body 100 is moved leftward along the guide rail 200 to the left lane line of the tidal lane 230, and then the guardrail body 100 extends along the length direction of the left lane line. At this time, the movable rod 15 is inserted into the positioning hole 211 on the left lane line to position the guardrail body 100. At this time, the guardrail body 100 separates the tidal lane 230 from the southbound lane 220, and at this time the tidal lane 230 is for vehicles to travel from south to north; and when it comes to the time period when there are more vehicles traveling from north to south, first retract the guardrail body 100 to the smallest state. When the guardrail body 100 is retracted, the guide rod 14 sequentially passes through the guide holes 13 on the middle upright 10 and extends into the guide hole 13 on the first upright 10 to play a guiding role in the retraction of the guardrail body 100. And when the guide rod 14 extends into the guide hole 13 on the first upright 10, the guide rod 14 acts on the inclined surface of the inclined surface guide hole 151 to drive the movable rod 15 to move upward, so that the movable rod 15 disengages from the positioning hole 211 on the left lane line. At this time, the retracted guardrail body 100 can be moved along the guide rail 200 to the right lane line of the tidal lane 230, and then the guardrail body 100 is extended along the right lane line. After the guide rod 14 disengages from the inclined surface guide hole 151, the movable rod 15 moves downward under the action of the compression spring 16 and is inserted into the positioning hole 211 on the right lane line to position the guardrail body 100. At this time, the guardrail body 100 can stably extend along the right lane line to the longest state. In this way, the guardrail body 100 separates the tidal lane 230 and the northbound lane 240, and at this time the tidal lane 230 is for vehicles to travel from north to south.

[0042] Through the linkage of components such as the guide rod 14, the movable rod 15, the compression spring 16, and the positioning hole 211, the movable guardrail realizes functions such as telescopic movement, automatic locking and unlocking, and stable limiting of the guardrail, effectively solving problems such as difficult movement, unstable fixation, and cumbersome operation of traditional tidal lane guardrails, greatly improving the operation convenience, safety, and adaptability of the guardrail, and having significant application value and promotion prospects.

[0043] This specification and the drawings are only exemplary descriptions of the present application, and are considered to have covered any and all modifications, changes, combinations, or equivalents within the scope of the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the present application and its equivalent technologies, the present application is intended to include these modifications and variations.
