Description

Technical Field

[0001] This utility model relates to the field of road maintenance operation technology, and in particular to a suspended traffic cone automatic deployment and retraction device. Background Technology

[0002] Currently, during highway maintenance operations in my country, traffic cones and other guiding signs need to be placed outside the work area to guide vehicle traffic. The placement and retrieval of traffic cones are mainly carried out manually and automatically. Among them, automatic operation equipment can ensure the personal safety of operators during the placement and retrieval of traffic cones. Compared with manual placement and retrieval of traffic cones, the operation speed is faster, the safety factor is higher, and the spacing of traffic cones is uniform. Therefore, it is very meaningful to improve the automatic placement and retrieval equipment for traffic cones.

[0003] A search revealed a patent document with publication number CN112796248A, which discloses an automatic traffic cone deployment and retrieval device. In this design, the deployment and retrieval device is mounted at the rear of a work vehicle's cargo compartment via a pulley-like transmission structure. This allows for the placement and retrieval of traffic cones at arbitrary intervals, either diagonally or in a straight line, without the work vehicle crossing road markings. The device consists of multiple foldable parts, enabling it to be folded and stored at the rear of the cargo compartment. However, this design still has drawbacks: due to the pulley transmission structure, the deployment and retrieval device is difficult to disassemble from the rear of the cargo compartment, and it cannot be completely stored inside. This increases the overall length of the work vehicle, reduces the portability of the device, and makes transportation inconvenient. Therefore, it is necessary to design a structure that can completely store the deployment and retrieval device within the cargo compartment. Utility Model Content

[0007] A second moving component is provided in the carriage to drive the retraction device body to move along the length of the carriage. The second moving component is movably connected to the first moving component. In use, the retraction device body is first adjusted to the rear entrance of the carriage by the first moving component, and then the second moving component is used to drive the first moving component and the retraction device body together to be retracted into the carriage from the entrance.

[0019] A second slider is provided at the bottom end of the base plate;

[0020] The rotating wheels are symmetrically arranged with respect to the second slider, and there is an movable gap between adjacent rotating wheels for the second guide rail to pass through.

[0021] As a preferred embodiment of this utility model, the base plate has multiple supporting beams, the bottom ends of which are fixed by the base plate, and the multiple supporting beams stacked longitudinally are slidably engaged by a slider structure and a guide rail structure.

[0022] As a preferred embodiment of this invention, the first moving component further includes:

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0045] like Figure 1 As shown, the suspended traffic cone automatic deployment and retraction device includes:

[0046] The retraction device body 20 and a first moving component for driving the retraction device body 20 to move along the width direction of the carriage 1;

[0047] A second moving component is provided in the carriage 1 to drive the retraction device body 20 to move along the length of the carriage 1. The second moving component is movably connected to the first moving component.

[0048] The above technical solution allows the retraction device body 20 to be completely stored in the carriage 1. In use, the first moving component is used to adjust the retraction device body 20 to the rear entrance of the carriage 1 to ensure that the retraction device body 20 does not interfere with the movement of the carriage 1 entrance. Then, the second moving component is used to drive the first moving component and the retraction device body 20 together from the entrance into the carriage 1, thereby reducing the overall length of the work vehicle and improving the portability of the retraction device.

[0049] like Figure 1 As shown, in this embodiment, the first moving component includes: a slider structure disposed at the bottom end of the retractable device body 20; a plurality of support beams 4; and a guide rail structure disposed at the upper end of the support beams 4 and cooperating with the slider structure, wherein the retractable device body 20 can slide relative to the support beams 4 through the slider structure and the guide rail structure; and a shrinking structure for folding and storing adjacent support beams 4 to reduce the total length of the support beams 4.

[0050] The above technical solution enables the placement and collection of traffic cones. During use, because the support beam 4 is equipped with a retractable structure, multiple support beams 4 can be combined to form a longer support beam 4. The total length of the support beam 4 exceeds the width of the vehicle compartment 1, which is sufficient to enable the placement and collection of traffic cones at any spacing, whether diagonal or straight, without the work vehicle crossing the road markings. At the same time, the retractable structure allows multiple support beams 4 to be folded and stored after the work is completed, so that the total length of the support beam 4 does not exceed the width of the entrance of the vehicle compartment 1, avoiding movement interference and facilitating storage in the vehicle compartment 1.

[0051] like Figure 3 As shown, in this embodiment, the retraction structure includes: hinges 7 disposed at the ends of two adjacent support beams 4; and locking components for locking or unlocking the movable state between adjacent support beams 4.

[0052] The above technical solution can achieve the storage and folding of the support beams 4 by rotation. When in use, fix one of the support beams 4, rotate the other support beam 4 to rotate around the hinge 7 until the ends of the two support beams 4 are attached, and then lock them with the locking component to form a longer support beam 4.

[0053] like Figure 3 As shown, in this embodiment, the locking component includes a positioning pin 9, which slides in a pin groove 8 formed in the support beam 4.

[0054] The above technical solution can prevent the support beams 4 from rotating relative to each other and improve the stability of the structure. When the ends of the two support beams 4 are in parallel, the positioning pin 9 is pushed into the pin groove 8 of the two support beams 4, thereby fixing the support beams 4 together.

[0055] like Figure 5 and Figure 7 As shown, in this embodiment, the locking component is a locking fastener 11 located at the hinge of adjacent support beams 4. The locking fastener 11 is divided into a first locking part and a second locking part, wherein the first locking part of one support beam 4 cooperates with the second locking part of the other support beam 4.

[0056] The above technical solution can further prevent the support beams 4 from rotating relative to each other. The use of locking fastener 11 in conjunction with positioning pin 9 can achieve double fixation and prevent the support beams 4 from rotating relative to each other. It should be noted that the locking fastener 11 and positioning pin 9 do not necessarily have to be used together. They can be used separately, but the locking effect is better when used in combination than when used alone.

[0057] like Figure 4 and Figure 6 As shown, in this embodiment, the guide rail structure includes: a second guide rail 10 disposed at the upper end of the support beam 4; the slider structure includes: a base plate 12 disposed at the bottom end of the take-up and release device body 20; a second slider 13 disposed at the bottom end of the base plate 12; and rotating wheels 14 symmetrically arranged about the second slider 13, with an movable gap between adjacent rotating wheels 14 for the second guide rail 10 to pass through.

[0058] The above technical solution can adjust the movement of the retractable device body 20 along the width direction of the carriage 1, that is, to realize the placement and collection of traffic cones at any spacing requirements, whether diagonal or straight, without the work vehicle crossing the road markings. When in use, by pushing the retractable device body 20, the rotating wheel 14 at the bottom of the second slider 13 is driven to slide along the second guide rail 10, thereby changing the working position of the retractable device body 20.

[0059] like Figure 4 and Figure 5 As shown, in this embodiment, the base plate 12 has multiple parallel support beams 4 whose bottom ends are fixed by the base plate 12, and the multiple support beams 4 stacked longitudinally achieve sliding cooperation through a slider structure and a guide rail structure.

[0060] The above technical solution can further improve the folding and storage effect of the support beam 4. The slider structure and guide rail structure can be used in conjunction with the hinge 7 to achieve rotational storage and sliding storage. When in use, push the upper support beam 4, so that the rotating wheel 14 at the bottom of the upper support beam 4 slides along the second guide rail 10 at the top of the lower support beam 4. When the two support beams 4 move away from each other, the overall length of the support beam 4 increases. Conversely, when the two support beams 4 are closed and overlapped, the overall length of the support beam 4 decreases. It should be noted that sliding storage and rotational storage do not need to be used together. They can be used separately. However, the combined use of the two is better than using them alone. It can provide a longer stroke for the retraction device body 20 without affecting storage in the carriage 1, which is suitable for operation on wider roads.

[0061] like Figure 6 As shown, in this embodiment, the first moving component further includes: a motor 15, which is disposed in a through slot 16 opened in the base plate 12; a frame 17 for fixing the motor 15, the frame 17 being fixedly connected to the base plate 12; a gear 18 connected to the output end of the motor 15; and a rack 19 disposed on one side of the support beam 4, the rack 19 meshing with the gear 18.

[0062] The above technical solution enables the automatic adjustment of the position of the retractable device body 20, as well as the automatic adjustment of the extension and retraction of the support beam 4. In use, the start motor 15 drives the gear 18 to rotate and mesh with the rack 19. Since the rack 19 is fixed, it can drive the gear 18 to move, thereby driving the motor 15 to move. The motor 15, together with the frame 17, drives the base plate 12 to slide, thereby realizing the adjustment of the position of the retractable device body 20 and the automatic adjustment of the extension and retraction of the support beam 4.

[0063] like Figure 1 and Figure 2 As shown, in this embodiment, the second moving component includes at least two second moving parts disposed opposite to each other in the carriage 1. The second moving part includes: a first sleeve rod 2 fixedly disposed in the carriage 1; a second sleeve rod 3 telescopically disposed in the first sleeve rod 2; a first guide rail 6 disposed at the upper end of the second sleeve rod 3; a first slider 5 slidably engaged with the first guide rail 6, the first slider 5 being fixedly disposed at the bottom end of the lowest support beam 4; a fixing block 21 is provided at the bottom of the first sleeve rod 2, and the fixing block 21 has bolt holes.

[0064] The above technical solution allows for easy storage of the support beam 4 and the retractable device body 20 into the carriage 1. After the operation is completed, the support beam 4 is folded to its minimum volume using the first moving component. At the same time, the retractable device body 20 is adjusted to the corresponding position at the entrance of the carriage 1. The first slider 5 at the bottom of the lowest support beam 4 is pushed, causing the first slider 5 to slide into the carriage 1 along the first guide rail 6 at the upper end of the first sleeve rod 2 and the second sleeve rod 3. Then, the second sleeve rod 3 is stored in the first sleeve rod 2, and the carriage door is closed to complete the storage. This is quite convenient. As a possible scenario, to facilitate storage, the first sleeve rod 2 and the second sleeve rod 3 can also be driven by a power device without manual operation. For example, a hydraulic cylinder can be used to extend and retract the first sleeve rod 2 and the second sleeve rod 3, thereby reducing the labor intensity of the operation.

[0065] like Figure 2 and Figure 7 As shown, in this embodiment, the first sleeve rod 2 and the first slider 5 are both provided with through threaded grooves on their sides. A threaded rod is threadedly connected in the threaded groove. One end of the threaded rod abuts against the inner slide of the first sleeve rod 2 and the first slider 5, thereby applying a fastening force to the second sleeve rod 3 and the first guide rail 6 respectively. A rotating handle is provided at the other end of the threaded rod.

[0066] The above technical solution can prevent the second sleeve rod 3 from extending or retracting relative to the first sleeve rod 2 due to accidental contact, and prevent the first slider 5 from sliding along the first guide rail 6 due to accidental contact, thereby improving the stability of the structure. In use, rotating the handle can drive the threaded rod to rotate, thereby making one end of the threaded rod abut against the second sleeve rod 3 or the first guide rail 6, thus restricting the degree of freedom of sliding.

[0067] Working principle: When traffic cones need to be deployed, push the second set of rods 3 to slide it out relative to the first set of rods 2 until all support beams 4 slide out of the carriage 1. Rotate one support beam 4 to make it rotate around the hinge 7 of the other support beam 4 until the ends of the two support beams 4 are in contact. Use locking parts such as locking fasteners 11 and / or positioning pins 9 to lock the support beams 4 together, so that a longer support beam 4 can be formed. On this basis, the motor 15 can be started to drive the gear 18 to rotate and mesh with the rack 19. Since the rack 19 is fixed, it can drive the gear 18 to move, thereby driving the motor 15 to move. The motor 15, together with the frame 17, drives the base plate 12 to slide, thereby realizing that the longitudinally arranged support beams 4 are spread apart and increase the total length of the support beams 4, further increasing the stroke of the retraction device body 20. By controlling the motor 15 of the base plate 12 where the retraction device body 20 is located, the position of the retraction device body 20 on the lane can be adjusted to facilitate the spacing of traffic cones.

[0068] When the operation is completed, and the main body 20 of the retraction device needs to be stored in the carriage 1, the motor 15 is started to drive all the longitudinally arranged support beams 4 to close and overlap with each other. Then, the locking component releases the rotation restriction of the hinge 7, and the support beam 4 rotates around the hinge 7, thereby reducing the overall length of the hinge 7 until the total length is less than the width of the entrance of the carriage 1. Then, the first slider 5 at the bottom of the lowest support beam 4 is pushed, so that the first slider 5 slides into the carriage 1 along the first guide rail 6 at the upper end of the first sleeve rod 2 and the second sleeve rod 3. Then, the second sleeve rod 3 is stored in the first sleeve rod 2, and the door of the carriage 1 is closed to complete the storage.
