Description

Technical Field

[0002] Safety cones play a vital role in highway construction, maintenance, and traffic accident handling. They can effectively isolate the work area, warn passing vehicles, temporarily separate traffic, guide traffic, ensure the safety of construction site facilities and personnel, and reduce the risk of accidents.

[0003] The traditional manual safety cone retraction and deployment method has problems such as low operating efficiency and high traffic safety risks. In order to solve the problem of manual retraction and deployment, some mechanized automatic arrangement devices have appeared on the market. For example, the retraction and deployment of the equipment is carried out by using an obliquely set track structure. The retraction and deployment guide rods used in this equipment are all cross bars plus free guide wheels. The guiding process is affected by the ground friction coefficient and the rotation performance of the guide wheel. The time taken for each safety cone to complete the guiding process varies, the operating efficiency cannot be steadily improved, the placement position deviation is large, and it is difficult to ensure the spacing accuracy. There are also methods that use manipulator grasping, but this method has poor grasping effect, high requirements on the flexibility of the manipulator, large movement range, high maintenance cost, and slow retraction and deployment speed. In addition, although some existing automatic retraction and deployment equipment can realize the retraction and deployment function to a certain extent, they still have limitations, such as failure to achieve full automatic operation, and personnel are required to stack safety cones on the vehicle. Therefore, it is urgent to develop an efficient, simple, reliable and low-cost automatic sending and receiving device for safety cones. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0031] The invention discloses a rear-mounted safety cone retracting and releasing device.

[0032] Reference Figure 1A rear-mounted safety cone retracting and releasing device includes a working platform 1, a retracting and releasing guide rod 2, a floating displacement rod 3 and a flip clamp rod 4; the working platform 1 includes a vertical plate body 11, a connecting plate body 13 and a horizontal plate body 12, the bottom end of the vertical plate body 11 is fixedly connected to the horizontal plate body 12, the connecting plate body 13 is fixed to the side wall of the vertical plate body 11 away from the horizontal plate body 12, and the connecting plate body 13 is arranged parallel to the horizontal plate body 12.

[0033] The two side walls of the horizontal plate body 12 at one end away from the vertical plate body 11 are hinged with a clamping rod 6, and a clamping motor for driving the clamping rod 6 to rotate around the horizontal plate body 12 is installed on the hinge shaft between the clamping rod 6 and the horizontal plate body 12. A clamping claw 7 is installed at one end of the clamping rod 6 away from the horizontal plate body 12, and the clamping claw 7 is rotatably connected between the two clamping rods 6. The clamping claw 7 is kept vertically downward under the action of its own weight. The clamping claw 7 is used to clamp the safety cone. The clamping claw 7 can adopt a mechanical structure driven by a motor or a pneumatic or hydraulic type to open and close the clamping claw.

[0034] The two opposite outer side walls of the horizontal plate body 12 are hinged with the two floating displacement rods 3, and a floating cylinder 33 is provided between each floating displacement rod 3 and the working platform 1, and the two ends of the floating cylinder 33 are respectively hinged with the floating displacement rod 3 and the working platform 1. The floating cylinder 33 is connected with a four-position solenoid valve; when the safety cone is recovered, the four-position solenoid valve is placed in the left middle position, and the floating cylinder 33 is connected to the accumulator, so that the floating cylinder 33 forms a gas spring, which is used as a pre-tightening element of the floating displacement rod 3.

[0035] The end of each floating displacement rod 3 away from the working platform 1 is connected to the retractable guide rod 2, which includes a guide rod body 21, a driving motor 23, a driving wheel 24, a belt 25, a driven wheel 26 and a plurality of supporting wheels 22. One end of the guide rod body 21 is hinged to the floating displacement rod 3 and is connected to a steering motor for driving the retractable guide rod 2 to deflect around the end of the floating displacement rod 3. The driving wheel 24 and the driven wheel 26 are rotatably mounted on the two ends of the guide rod body 21 respectively; the plurality of supporting wheels 22 are rotatably connected to the guide rod body 21 and arranged between the driving wheel 24 and the driven wheel 26. The belt 25 is tensioned around the driving wheel 24, the driven wheel 26 and the outer side of the support wheel 22. The driving motor 23 is fixed to the guide rod body 21 by bolts. The output shaft of the driving motor 23 is coaxially fixed with the driving wheel 24 to drive the driving wheel 24 to rotate, thereby driving the belt 25 to operate. The belt 25 drives the safety cone to move toward the center of the inner guide area through rotation. In order to optimize the guiding effect, the outer wall of the belt 25 is provided with a raised pattern. The setting of the support wheel 22 can effectively prevent the belt 25 from being pushed by the safety cone to bend in the opposite direction, thereby ensuring the stability and reliability of the guiding process.

[0036] A fan-shaped retracting area is formed between the two retracting guide rods 2, and the opening and closing angle range of the fan-shaped retracting area formed between the two retracting guide rods 2 is 0-180°, so that the safety cones at different positions can be guided to the designated position for recovery.

[0037] The two side walls of the connecting plate body 13 away from the vertical plate body 11 are hinged with a flip clamp rod 4, and the hinge shaft between the flip clamp rod 4 and the connecting plate body 13 is connected with a flip motor that can drive the flip clamp plate to rotate around the connecting plate body 13. The top of the connecting plate body 13 away from the vertical plate body 11 is installed at the rear of the vehicle body through a sliding guide rail 5, so that the device as a whole can slide left and right along the vehicle body.

[0038] A caster 32 is installed on the side wall of one end of the floating displacement rod 3 away from the horizontal plate body 12, and is used to support the floating displacement rod 3 to keep it stable.

[0039] A notch is provided in the middle of one end of the horizontal plate 12 away from the vertical plate 11, and a rotating clamping cylinder 8 is installed in the notch. When the clamping rod 6 drives the safety cone to flip forward to the desired position through the clamping claw 7, the safety cone is clamped by the rotating clamping cylinder 8, and then the safety cone is driven to rotate to adjust the angle and orientation of the safety cone.

[0040] A positioning sensor 31 is installed on the top wall of the floating displacement rod 3 near the retracting guide rod 2. Under the guidance of the retracting guide rod 2, the safety cone moves to the end of the retracting guide rod 2 near the floating displacement rod 3, and then triggers the positioning sensor 31, thereby triggering the subsequent recovery operation.

[0041] The invention also discloses a method for sending and receiving a rear-mounted safety cone.

[0042] Reference Figures 2 to 9, a rear-mounted safety cone sending and receiving method, adopts the above-mentioned safety cone retracting and releasing device. When performing the recovery operation: the device is located as a whole in the middle of the rear side of the vehicle, and the floating cylinder 33 makes the retracting guide rod 2 and the floating displacement rod 3 flat on the ground; at this time, the caster 32 touches the ground, and the four-position solenoid valve of the floating cylinder 33 is placed in the left middle position. The floating cylinder 33 is connected to the accumulator, so that the floating cylinder 33 forms a gas spring, which is used as a pre-tightening element of the floating displacement rod 3; then, the fan-shaped retracting area formed between the two retracting and releasing guide rods 2 guides the traffic cones at different positions to the designated position for recovery; specifically, the driving motor 23 drives the belt 25 to rotate, and the belt 25 drives the safety cone to the guide through friction. The center position of the guide area is moved until the side position sensor 31 is triggered; then the clamping rod 6 drives the clamping claw 7 to flip toward the direction of the safety cone, the clamping claw 7 clamps the safety cone, and then flips toward the working platform 1. During this process, the safety cone is first lifted and approaches the working platform 1, and finally placed on the horizontal plate 12 of the working platform 1; then, the rotating clamping cylinder 8 clamps and fixes the safety cone, and after rotating and adjusting the angle and orientation of the safety cone, the safety cone is released; finally, the flipping clamping rod 4 drives the safety cone to flip toward the direction close to the vehicle body, thereby placing the safety cone on the recovery platform to complete the recovery of the traffic cone.

[0043] During the deployment operation: the device is located as a whole on the left side of the rear of the vehicle, and the floating cylinder 33 places the retractable guide rod 2 and the floating displacement rod 3 almost parallel to the ground. At this time, the caster 32 does not touch the ground, and the four-position solenoid valve of the floating cylinder 33 is in the right middle position, and the cylinder is locked; the flip clamp rod 4 clamps the safety cone on the recovery platform from above, flips downward, and places the safety cone on the horizontal plate 12 of the working platform 1, then, the rotating clamping cylinder 8 clamps and fixes the safety cone, and after adjusting the angle and orientation of the safety cone, the safety cone is released; then, the clamping claw 7 clamps the safety cone, and the clamping rod 6 drives the clamping claw 7 to flip away from the working platform 1, places the safety cone on the ground and releases it; finally, the safety cone is guided to the specified position by the retractable guide rod 2 to complete the deployment of the safety cone.
