Description

Technical Field

[0001] The utility model relates to the technical field of road guardrails, in particular to a municipal isolation belt. Background Technique

[0002] The isolation belt is usually installed in the middle of urban roads to separate the motor vehicle lane from the non-motor vehicle lane or the sidewalk. When a vehicle accidentally deviates from the normal driving lane, it will rush towards the isolation belt. However, traditional isolation belts are rarely equipped with special buffer materials and cannot play a role in buffering and energy absorption when the vehicle hits, so the vehicle almost directly hits the rigid frame and railing. The strong impact force will cause the vehicle to be severely deformed and cause fatal injuries to the people in the vehicle. If the isolation belt is damaged or displaced, it will also affect the cyclists on the non-motor vehicle lane or the pedestrians on the sidewalk.

[0003] Therefore, in order to solve the defect of poor anti-collision performance caused by the lack of special buffer materials in the isolation belt, it is very necessary to propose a municipal isolation belt. Content of the Utility Model

[0004] The purpose of the utility model is to provide a municipal isolation belt, which can absorb part of the energy and disperse the impact force when the vehicle hits through the rubber seat, the roller, the corrugated railing and the diamond-shaped connecting metal plates between the railings, so that the impact force will not concentrate on a certain point, reduce the degree of vehicle deformation, and reduce the risk of fatal injuries to the people in the vehicle, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A municipal isolation belt includes a rubber seat and columns. The columns are fixedly installed on the left and right sides and the middle of the upper end of the rubber seat. The columns in the middle are arranged symmetrically front and back and there are multiple of them. The adjacent columns on the left and right are connected with railings through clamps. The surface of the railing is corrugated, and a metal plate is supported between the front and back railings. The metal plates are distributed in a diamond shape and form a continuous and dense array structure;

[0007] The column includes a bent pipe. The left and right ends of the bent pipe are both installed with rollers at intervals up and down. The inside of the roller is hollow and the cylinder body is made of steel material. The clamp is fixedly connected with the bent pipe.

[0008] Preferably, the distance between adjacent columns on the left and right is kept consistent and controlled within 0.5 - 0.8 m.

[0009] Preferably, the rubber seat is trapezoidal and the bottom expands outwards.

[0010] Preferably, the bottom of the bent pipe is strengthened by a reinforcing rod to increase the structural strength.

[0011] Preferably, a cross bar is welded between the left and right elbow pipes, and the cross bar and the reinforcing bar are on the same horizontal line.

[0012] Preferably, a first vertical bar and a second vertical bar are welded between the front and rear elbow pipes. The first vertical bar is welded to the bottom of the elbow pipe, and the second vertical bar is welded in a circular array to the top of the elbow pipe.

[0013] Preferably, grooves for the rollers to rotate are provided at the left and right ends of the railing.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. For this municipal isolation belt, by setting the surface of the railing to be corrugated, the railing can deform when impacted by a vehicle, and absorb energy through its own deformation, thereby reducing the impact force borne by the vehicle.

[0016] 2. For this municipal isolation belt, by arranging metal plates in a rhombus distribution between the front and rear railings to form a continuous and dense array structure, due to the good stability and dispersive force characteristics of the rhombus structure, when a vehicle impacts the isolation belt, if the impact force acts on the railing, the metal plate can disperse the concentrated impact force to each rhombus unit, avoiding the impact force concentrating on a certain point, thereby further reducing the deformation degree of the vehicle.

[0017] 3. For this municipal isolation belt, the rollers also play an important buffering role. When a vehicle impacts the isolation belt, the rollers can rotate, and this rotation converts part of the impact energy of the vehicle into the rotational kinetic energy of the rollers, reducing the impact force directly borne by the vehicle.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 - Figure 2 , a municipal isolation belt, including a rubber seat 1 and a column 2. The rubber seat 1 is trapezoidal and its bottom expands outwards.

[0024] Among them, the bottom of the rubber seat 1 expands outwards, increasing the contact area with the ground, making the rubber seat 1 more stable on the ground, not easily sinking or tilting, providing stable support for the column 2, and when a vehicle hits the isolation belt, the rubber seat 1 can deform to absorb part of the impact energy to form a buffer.

[0025] Please refer to Figure 1 - Figure 2 , the column 2 is fixedly installed on the left and right sides and the middle of the upper end of the rubber seat 1. The column 2 in the middle is arranged symmetrically front and back and there are multiple of them. The distance between adjacent columns 2 on the left and right is kept consistent and controlled within 0.5 - 0.8 m.

[0026] Among them, setting the distance between the columns 2 within 0.5 - 0.8 m can improve the overall stability of the isolation belt by shortening the column distance, preventing excessive local deformation or even fracture when the vehicle hits, and when the vehicle hits, the impact force will be transmitted to the column 2. Since the columns 2 are evenly distributed, the impact force will be dispersed to each column 2, and the columns 2 are arranged symmetrically front and back, which can well resist the impact force from the front and back directions and maintain the stability of the isolation belt.

[0027] Please refer to Figure 1 - Figure 3 , the column 2 includes a bent pipe 21. The bottom of the bent pipe 21 is strengthened by a reinforcing rod 24 to increase the structural strength. A cross bar 4 is welded between the left and right bent pipes 21. The cross bar 4 and the reinforcing rod 24 are on the same horizontal line. A first vertical rod 5 and a second vertical rod 6 are welded between the front and back bent pipes 21. The first vertical rod 5 is welded to the bottom of the bent pipe 21, and the second vertical rod 6 is welded to the top of the bent pipe 21 in a circular array.

[0028] Among them, the setting of the reinforcing rod 24 can provide additional support force for the bent pipe 21, improve the overall stability of the bent pipe 21, and thus reduce the bending deformation at the bottom of the bent pipe 21;

[0029] The arrangement of the cross bar 4, the first vertical bar 5 and the second vertical bar 6 forms a more stable frame structure between the columns 2, and enhances the connection strength between the columns 2. When a vehicle collides, it can effectively resist external forces, and the forces are transmitted and dispersed to each other through the welding points. The impact force will be transmitted to the cross bar 4, the reinforcing bar 24, the first vertical bar 5 and the second vertical bar 6 through the bent pipe 21, so that the impact force is redistributed, thereby improving the stability of the entire isolation zone.

[0030] See also Figure 1 - Figure 2 The left and right ends of the curved pipe 21 are both provided with rollers 22 at intervals therebetween. The interior of the roller 22 is hollow and the cylinder body is made of steel.

[0031] Among them, the roller 22 can play a role in reducing friction. When a vehicle accidentally hits the isolation belt, the roller 22 can rotate. Compared with the direct friction between the vehicle and the rigid surface of the curved pipe 21, the coefficient of rolling friction is much smaller. The smaller friction can reduce the degree of damage to the vehicle during the collision, and also reduce the impact force on the isolation belt;

[0032] In addition to reducing friction, the roller 22 can also disperse impact force. The hollow structure allows the roller 22 to have a certain deformation space when it is hit. According to the law of conservation of energy, part of the vehicle's kinetic energy will be converted into deformation energy of the roller 22 during a collision. The steel material has high lightness and toughness and can withstand greater impact force.

[0033] See also Figure 1 - Figure 3 A guardrail 3 is connected between two adjacent left and right columns through a clamp 23. Grooves 31 for the roller 22 to rotate are provided on the left and right ends of the guardrail 3. The surface of the guardrail 3 is corrugated, and a metal plate 32 is supported between the front and rear guardrails 3. The metal plates 32 are distributed in a diamond shape and form a continuous and tight array structure.

[0034] The surface of the guardrail 3 is arranged in a corrugated shape. The corrugated structure increases the bending resistance of the guardrail 3, making it less likely for the guardrail 3 to bend and deform when hit by a vehicle. At the same time, from a visual effect point of view, the corrugated surface can play a certain warning role. Its irregular shape can attract the attention of the driver and remind the driver of the existence of the isolation belt.

[0035] The diamond-shaped array structure of metal plates 32 can significantly enhance the overall structural strength of the guardrail 3. In mechanical structure, the diamond structure has good stability. When the isolation zone is impacted by external force, the metal plate 32 can effectively transmit and disperse the force. The force will be transmitted along the diagonal and four sides of the diamond to avoid local stress concentration and damage to the guardrail 3. At the same time, the diamond structure is prone to deformation when subjected to force. This deformation can absorb energy and play a buffering role.
