Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of equipment and devices for constructing new road surfaces and repairing or rebuilding completed road surfaces, specifically relating to equipment for deploying and retracting traffic cones. Background Technology
[0002] With the continuous increase in the mileage of highways in my country and the rapid growth of various motor vehicles, asphalt pavements will develop potholes, bulges, large-area cracks, and eventually become unusable after a long period of operation. The maintenance workload of asphalt pavements is increasing day by day. When carrying out local repairs on asphalt pavements, rubber cones are first placed to partially close traffic and repair the road surface. The placement and removal of traffic cones are usually carried out manually. For longer sections, the placement and removal of traffic cones are carried out by 2 to 3 construction workers along a specific route on the highway from the rear of the road construction vehicle. This manual operation method is slow, has a low safety factor, and the spacing of traffic cones is not uniform.
[0003] Chinese patent application number 2011103853553, entitled "Automatic Traffic Cone Deployment and Retrieval Device," discloses a device comprising a cone deployment device, suspension and guiding devices at both ends of the deployment device, and a support device at the bottom of the deployment device. This device can only achieve stable deployment of traffic cones but cannot automatically retrieve them; its function is limited and it does not significantly save manpower or improve efficiency.
[0004] Chinese patent application number 2010101059926, entitled "Automatic Traffic Cone Deployment and Retraction Device," includes a suspension device and a deployment and retraction device. The suspension device controls the lifting and lowering movement of the deployment and retraction device, which deploys the traffic cones via a chute and a directional device, and retracts the traffic cones via a chain and a rolling lever driven by a motor. While this device can deploy and retract traffic cones, the entire process still requires manual operation; the traffic cones retrieved into the vehicle compartment must be manually placed. Therefore, this automatic traffic cone deployment and retraction device is essentially a semi-automatic device and cannot achieve fully automated operation without human intervention.
[0005] To solve the above-mentioned technical problems, the designer of this utility model designed a traffic cone retraction vehicle. The main component of this vehicle, the traffic cone lifter, has been patented in China, patent application number 2023233233276, invention titled "Traffic Cone Retraction Device." During engineering construction, the following main drawbacks were found in this traffic cone retraction device:
[0006] The aforementioned traffic cone lifters can only be used to lift traffic cones when they are placed. They cannot lift traffic cones that have fallen over on the road surface, requiring manual uprighting. They also cannot properly retrieve traffic cones that have fallen over on the road surface, increasing road maintenance costs. Summary of the Invention
[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a traffic cone straightening and straightening device with reasonable design, simple structure, good performance, and the ability to straighten and straighten traffic cones that have fallen on the road surface.
[0008] The technical solution adopted to solve the above technical problem is as follows: two connecting plates are set on the cross frame, and inverted conical rods are set on the two connecting plates. A connecting frame is set on the front and rear sides of the lower surface of the cross frame. A limit frame is set on each connecting frame, and a correction wheel assembly is set on the front connecting frame.
[0009] The limiting frame of this utility model is composed of limiting wheels set on the limiting tube.
[0010] The limiting tube of this utility model is composed of an arc-shaped tube with a radius R of 300-400mm and a central angle of 90°, which is integrated with a horizontal tube. The vertical cross-section of the limiting tube is rectangular. Five to 15 limiting wheels are provided on the outer surface of the arc-shaped tube of the limiting tube, and four to 10 limiting wheels are provided on the lower surface of the horizontal tube of the limiting tube.
[0011] The geometric shape of the limiting tube of this utility model is an arc-shaped tube with a radius R of 330mm and a central angle of 90° integrated with a horizontal tube. Ideally, nine limiting wheels are provided on the outer surface of the arc-shaped tube of the limiting tube, and six limiting wheels are ideally provided on the lower surface of the horizontal tube of the limiting tube.
[0012] The calibration wheel assembly of this utility model is as follows: a conical wheel frame is provided behind the calibration frame, a pressure spring is provided on the connecting rod between the calibration frame and the conical wheel frame, and 2 to 8 conical wheels are provided on the left side of the upper surface of the left side of the conical wheel frame, and 5 to 20 conical wheels are provided on the lower end face.
[0013] The left side of the upper surface of the conical wheel frame of this utility model is preferably provided with 6 conical wheels, and the lower end surface is preferably provided with 14 conical wheels. The conical wheel frame is provided with a conical wheel frame connecting plate.
[0014] The geometric shape of the conical wheel frame of this utility model is that the left end of the plate-shaped body is processed into a truncated bevel with a continuous angle, the right side is processed into a plate-shaped body bent downward with a center line angle α of 10° to 30°, the right end is processed into a plate-shaped body bent downward with a center line angle β of 25° to 45°, and the right end is processed into a semi-circular arc bevel.
[0015] The geometric shape of the conical wheel frame of this utility model is that the left end of the plate is processed into a truncated bevel with a chamfered angle, the right side is processed into a plate that is bent downwards to form a center line angle α with an optimal value of 22.5°, the right end is processed into a plate that is bent downwards to form a center line angle β with an optimal value of 36°, and the right end is processed into a semi-circular arc chamfer.
[0016] Because this invention employs a correction wheel assembly, when correcting the posture of a traffic cone, the upright traffic cone is moved to the middle of the two limit frames by the limit frame. The traffic cone retrieval vehicle continues to reverse, and the conical wheel pushes the traffic cone base. The conical wheel acts as a guide, aligning any straight edge of the traffic cone base with the vehicle's reversing direction. As the traffic cone retrieval vehicle continues to reverse, the cone rod collides with the cone surface of the traffic cone, and the conical wheel at the upper end of the cone wheel frame further adheres to the traffic cone base, causing the traffic cone to tip over onto the ground. The traffic cone base is now facing the traffic cone retrieval vehicle, and the straight edge of the traffic cone base in contact with the ground is perpendicular to the vehicle's reversing direction—this is the desired posture. This invention features a simple structure, good performance, and the ability to correct and upright traffic cones that have fallen onto the road surface. It can be used in traffic cone retrieval devices. Attached Figure Description

[0041] The working process of this utility model is as follows:
[0042] Figure 7 A schematic diagram illustrating the principle of this utility model for correcting irregular traffic cones on road surfaces is provided. Figure 7 During construction, the left side of this utility model is installed at the rear of the traffic cone retraction vehicle. The process of retracting the traffic cone is a reversing operation. When correcting the posture of the traffic cone, the upright traffic cone is moved to the middle of the two limit frames 4 by the limit frame 4. The traffic cone retraction vehicle continues to reverse, and the conical wheel 5-6 pushes the traffic cone base. The conical wheel 5-6 acts as a guide, so that any straight edge of the traffic cone base is consistent with the reversing direction of the vehicle. The traffic cone retraction vehicle continues to reverse, and the reversing cone rod 3 collides with the cone surface of the traffic cone. At this time, the conical wheel 5-6 at the upper end of the conical wheel frame 5-1 further adheres to the traffic cone base, and finally flips the traffic cone to the ground, so that the traffic cone base faces the traffic cone retraction vehicle, and the straight edge of the traffic cone base in contact with the ground is perpendicular to the reversing direction of the vehicle, which is the desired posture.
[0043] Figure 8 A schematic diagram illustrating the principle of how the corrected traffic cone is laid down is provided. Figure 8 In this invention, when correcting a traffic cone at a special angle, the traffic cone base will press against the conical wheel 5-6, and the conical surface will press against the rear limit frame 4. At this time, if the vehicle continues to reverse, the pressure spring 5-4 will be compressed, the conical wheel frame 5-1 will rotate forward, the entrance of the traffic cone base will become larger, and the traffic cone can enter the two limit frames 4. The compression spring 5-4 will return to its original position, and then the traffic cone posture can be corrected normally.
[0044] Figure 9A schematic diagram illustrating the principle of this invention for erecting traffic cones that have fallen onto the road surface is provided. Figure 9 During the placement of traffic cones, the traffic cone placement and retrieval vehicle moves forward. The placement and retrieval device of the traffic cone placement and retrieval vehicle places the traffic cone base horizontally on the ground with the vehicle's forward direction facing the vehicle. As the vehicle moves forward, the limiting wheel 4-2 on the left limiting tube 4-1 of the limiting frame 4 collides with the traffic cone chassis, lifting the traffic cone. The cone-shaped wheels 5-6 on the left and right sides of the cone wheel frame 5-1, which are in a straight line in the left and right directions, guide the traffic cone and finally lift it up, completing the posture correction.
