Description

Technical Field

[0001] This utility model relates to the field of road traffic equipment, and in particular to an automatic traffic cone placement device based on a small truck. Background Technology

[0002] Traffic cones, also known as cone-shaped road signs, are a type of road traffic isolation and warning facility. They are placed in the middle of the road, in dangerous areas, and at the bottom of road construction sites. They are used to temporarily separate traffic flow, guide traffic, direct vehicles to bypass dangerous sections, protect construction site facilities and personnel, or other appropriate locations.

[0003] Currently, traffic cones are mainly deployed in two ways: First, manual placement requires workers to repeatedly bend over to pick up and place cones on the road, which is extremely labor-intensive and can easily lead to fatigue when deploying over long distances. At the same time, workers have to move through traffic and face the high risk of being hit by passing vehicles, especially on highways and other roads with heavy traffic, where safety is difficult to guarantee. In addition, manual placement is inefficient and cannot meet the needs of rapid deployment in emergency scenarios.

[0004] Secondly, large-scale dedicated traffic cone deployment vehicles are used. Although such equipment can be deployed automatically, it is bulky, has high purchase and maintenance costs, and has poor mobility in complex scenarios such as narrow urban roads and rural suburban roads, making it difficult to pass flexibly. Moreover, it requires dedicated vehicles to carry it, has a low adoption rate, and is not suitable for the daily operation needs of small and medium-sized construction units or grassroots emergency departments.

[0022] Example 1 See Figures 1 to 5This utility model provides an automatic traffic cone placement device based on a small truck, including a bracket 1 installed on the side panel of the cargo box. The main body of the bracket 1 is a rectangular frame structure, and two hooks 2 are fixedly installed at the upper end of the bracket 1. The bracket 1 is connected to the side panel of the cargo box through the hooks 2. A set of guide plates 3 are respectively installed on the four side walls of the bracket 1. The multiple sets of guide plates 3 form a receiving space for placing the traffic cone 17. The upper end of the receiving space is the inlet of the traffic cone 17, and the lower end is the outlet of the traffic cone 17. Two sets of lowering components 4 are symmetrically installed on the hanger 1 at the exit of traffic cone 17. The two sets of lowering components 4 are linked by the control component. The lowering component 4 includes a mounting base 6 fixedly mounted on the guide plate 3. The mounting base 6 has two sliding grooves 7, which are arranged in parallel. A limiting plate 8 is slidably mounted in each sliding groove 7. A driver 9 is rotatably mounted on the guide plate 3. A rotating shaft 10 is fixedly mounted in the middle of the driver 9. The rotating shaft 10 is rotatably connected to the hanger 1. A connecting rod 11 is rotatably mounted at each end of the driver 9. The connecting rod 11 is rotatably connected to the limit plate 8.

[0023] The hanger 1 is connected to the side panel of the cargo box of the small truck via two hooks 2 at its upper end, so that the hanger 1 is in a suspended state. In the initial state, the lower limiting plate 8 in the lower component 4 extends along the slide groove 7 of the mounting seat 6 to form a bottom limit on the traffic cone 17 in the accommodating space; the upper limiting plate 8 is in a retracted state and does not intervene to limit the traffic cone 17. Traffic cones 17 are placed into the upper part of the receiving space one by one. The traffic cones 17 are vertically stacked and arranged under the limiting and guiding action of multiple sets of guide plates 3. The bottom plate of the lowest traffic cone 17 abuts against the limiting plate 8 extending below. When it is necessary to release the traffic cone 17, the driver 9 on the guide plate 3 is driven by the control component to rotate around the rotating shaft 10. During the rotation of the driver 9, the connecting rods 11 at both ends of the driver 9 synchronously drive the upper and lower limit plates 8 to move. The lower limit plate 8 retracts along the slide groove 7, releasing the bottom limit of the lowermost traffic cone 17; at the same time, the upper limit plate 8 extends along the slide groove 7 and inserts into the gap between the bottom plate of the lowermost traffic cone 17 and the bottom plate of the adjacent traffic cone 17 above, forming a lifting limit for the traffic cones 17 stacked above. After the lowest traffic cone 17 loses its lower limit, it falls to the ground under its own weight to complete its placement. Then, the control driver 9 rotates in the opposite direction, which drives the limit plate 8 to reset through the connecting rod 11. The upper limit plate 8 retracts, releasing the support of the upper traffic cone 17. The lower limit plate 8 extends again along the slide 7 to limit the next traffic cone 17 falling to the bottom, completing one traffic cone placement cycle. After waiting for the next release command, the above actions are repeated.

[0024] By alternating the actions of the upper and lower limit plates 8, when releasing the traffic cone 17, the upper limit plate 8 inserts into the gap between the bottom plates of the adjacent traffic cone 17 to support the stack above, and the lower limit plate 8 retracts to release the lowest traffic cone 17. This can strictly control the release of only one traffic cone 17 at a time, completely avoiding the problem of multiple releases at a time and the continuous fall of traffic cones 17, and ensuring the accuracy of the placement spacing and quantity. The forward and reverse rotation of the driver 9 drives the limit plate 8 to reciprocate alternately, replacing manual bending over to place the items and greatly reducing the labor intensity of the workers.

[0025] Small trucks are commonly used in engineering, transportation, and emergency response fields, and have a high penetration rate. This device does not rely on special vehicles and can be used with just ordinary small trucks, which reduces the application threshold and purchase cost of the equipment. It can be quickly deployed with small trucks to various scenarios such as road construction, accident handling, and temporary traffic control, realizing the dynamic and mobile placement of traffic cones 17, and solving the problem that fixed equipment or large vehicles cannot respond quickly.

[0026] Operators can conveniently replenish traffic cones 17 to the device's storage space from inside the cargo box, and the loading capacity of the small truck can support the device to carry a sufficient number of traffic cones 17, reducing the number of trips to retrieve cones; at the same time, the device relies on the movement of the small truck to achieve continuous deployment, and with the help of the automated lowering structure, it greatly improves the coverage and placement efficiency of traffic cones 17 in a single operation.

[0027] The control assembly includes a control lever 12 rotatably mounted on the hanger 1, a swing arm 13 fixedly mounted on the control lever 12, the middle part of the swing arm 13 being coaxial with the rotation axis 10 of the control lever 12, and a pull rod 14 rotatably mounted at each end of the swing arm 13. A swing arm 15 is rotatably connected to the movable end of each pull rod 14, and the end of the swing arm 15 away from the pull rod 14 is fixedly connected to the rotation axis 10.

[0028] The operator rotates the control lever 12 on the hanger 1. The control lever 12 drives the swing arm 13 fixed thereto to rotate around the coaxial rotation axis 10. Under the action of the pull rod 14, the swing arm 13 drives the corresponding swing arm 15 to rotate around the rotation axis 10. When the swing arm 15 rotates, it directly drives the rotation axis 10 and the driver 9 on the rotation axis 10 to rotate, thereby driving the connecting rod 11 of the lowering component 4 to move. The lower limit plate 8 retracts to release the limit, and the upper limit plate 8 extends and inserts into the gap of the bottom plate of the traffic cone 17. The lowest traffic cone 17 falls down under the action of gravity. After the traffic cone 17 is dropped, the operator rotates the control lever 12 in the opposite direction, and the swing lever 13 rotates in the opposite direction accordingly. The pull rods 14 at both ends of the swing lever 13 simultaneously push the swing arm 15 to rotate in the opposite direction. The swing arm 15 drives the rotating shaft 10 and the driver 9 to reverse, so that the limit plate 8 of the lowering component 4 is reset, and all components of the control component also return to their initial state, waiting for the next operation.

[0029] The control components transmit power through a mechanical transmission structure consisting of a joystick 12, a swing lever 13, a pull rod 14, and a swing arm 15. They have no complex electronic components and are less affected by factors such as road construction and outdoor environment. Operators only need to turn the control lever 12 to drive the entire lowering component 4. The operation is simple and intuitive, and no professional training is required.

[0030] A tension spring is also provided on the hanger 1, and the tension spring is fixedly connected to the hanger 1 and the control lever 12 respectively.

[0031] Under the tension of the tension spring, the control lever 12 is pulled to the initial position. The lower limit plate 8 of the lowering component 4 remains extended, providing a stable limit for the traffic cone 17 in the accommodating space. The upper limit plate 8 is in a retracted state, which can effectively prevent the limit plate 8 from accidentally retracting due to vehicle bumps and vibrations. Structurally, this eliminates the possibility of the traffic cone 17 falling prematurely under unexpected conditions, improving the safety and reliability of the device during transportation and standby.

[0032] The hook 2 is inverted "L" shape. The horizontal part of the hook 2 is fixedly connected to the hanger 1, and the vertical part of the hook 2 forms a groove with the hanger 1. The side panel of the cargo box is located in the groove. A threaded hole is opened on the vertical part of the hook 2, and a locator 16 is threadedly connected in the threaded hole. The locator 16 includes a screw that is threadedly connected to the threaded hole. A knob is fixedly installed at one end of the screw, and a washer is rotatably installed at the other end. The washer is located in a slot.

[0033] Align the hook 2 with the side panel of the cargo box of the small truck, so that the side panel of the cargo box is inserted into the groove formed between the vertical part of the hook 2 and the bracket 1, thus completing the initial suspension and positioning of the bracket 1. Rotate the locator 16 to push the pad closer to the side panel of the cargo box in the slot until the pad is tightly against the surface of the side panel of the cargo box, thereby achieving a tight connection between the hook 2 and the side panel of the cargo box, and thus stably fixing the hanger 1 to the side panel of the cargo box.

[0034] By using a knob to drive the screw, the gasket is pushed against the side panel of the cargo box, which can effectively prevent the device from becoming loose or shifting due to bumps and vibrations during the ride of the truck. Moreover, the installation and fixing can be completed without the need for additional auxiliary tools, which greatly simplifies the installation process of this device and the truck.

[0035] The spacing between the two grooves 7 corresponds to the thickness of the base of the traffic cone 17.

[0036] The spacing of the groove 7 corresponds to the thickness of the base of the traffic cone 17, so that the upper limiting plate 8 can be inserted into the gap between two adjacent bases when it is in motion. Furthermore, the thickness of the limiting plate 8 is less than the spacing between the base plates of two adjacent traffic cones 17, so that when the upper limiting plate 8 is inserted into the gap between adjacent base plates, it will not squeeze and rub against the edge of the base plate due to the thickness and spacing being too tight. It can quickly and accurately intervene in the limiting position, effectively avoiding the insertion jamming problem caused by size interference.

[0037] When this utility model is used, the hanger 1 is connected to the side panel of the cargo box of the small truck through the two hooks 2 at its upper end, so that the hanger 1 is in a suspended state. In the initial state, the lower limiting plate 8 in the lower component 4 extends along the sliding groove 7 of the mounting seat 6 to form a bottom limit on the traffic cone 17 in the accommodating space; the upper limiting plate 8 is in a retracted state and does not intervene to limit the traffic cone 17. Traffic cones 17 are placed into the upper part of the receiving space one by one. The traffic cones 17 are vertically stacked and arranged under the limiting and guiding action of multiple sets of guide plates 3. The bottom plate of the lowest traffic cone 17 abuts against the limiting plate 8 extending below. When it is necessary to release the traffic cone 17, the driver 9 on the guide plate 3 is driven by the control component to rotate around the rotating shaft 10. During the rotation of the driver 9, the connecting rods 11 at both ends of the driver 9 synchronously drive the upper and lower limit plates 8 to move. The lower limit plate 8 retracts along the slide groove 7, releasing the bottom limit of the lowermost traffic cone 17; at the same time, the upper limit plate 8 extends along the slide groove 7 and inserts into the gap between the bottom plate of the lowermost traffic cone 17 and the bottom plate of the adjacent traffic cone 17 above, forming a lifting limit for the traffic cones 17 stacked above. After the lowest traffic cone 17 loses its lower limit, it falls to the ground under its own weight to complete its placement. Then, the control driver 9 rotates in the opposite direction, which drives the limit plate 8 to reset through the connecting rod 11. The upper limit plate 8 retracts, releasing the support of the upper traffic cone 17. The lower limit plate 8 extends again along the slide 7 to limit the next traffic cone 17 falling to the bottom, completing one traffic cone placement cycle. After waiting for the next release command, the above actions are repeated.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
