Description

Technical Field

[0001] This invention relates to the field of road maintenance technology, specifically to a traffic cone retraction and knocking device. Background Technology

[0002] In the field of road maintenance, the demand for automatic traffic cone deployment and retraction equipment is increasing. Existing equipment generally uses fixed rigid rods to guide and retract traffic cones. Although some manufacturers have added tangentially rotating rollers to the rigid rods to reduce friction, in actual operation, traffic cone jamming and inefficient sticking still occur frequently and cannot be fundamentally eliminated. This directly leads to a persistent difficulty in effectively improving equipment operating efficiency. Particularly in the limiting design of the figure-eight-shaped guide rod, external limiting plates are often used. However, in large-range floating mechanisms, multiple levels of external limiting plates are required to accommodate the large floating stroke. Furthermore, the numerous hinge points in this mechanism cause a significant increase in limiting sway due to clearances in the coupling pairs, making the guiding position of the traffic cone extremely unstable and severely affecting operational effectiveness.

[0003] Furthermore, existing technologies have significant shortcomings in the crucial traffic cone knocking-down stage of the recovery operation. Due to the relative slippage between the knocking rod and the cone surface, harmful frictional forces are generated, preventing the cone from tipping over. This is particularly pronounced when recovering traffic cones made of softer materials, easily leading to cone bending and disposal failure. This is the primary factor hindering the industrialization of automated traffic cone deployment and retrieval equipment. Simultaneously, traffic cone deployment and retrieval operations depend on the road construction environment, and construction sections often have uneven surfaces. Traditional traffic cone disposal devices are fixed to vehicles; when the road surface is uneven, the height difference between the disposal contact surface and the ground fluctuates significantly, leading to disposal failure and posing considerable difficulties for construction on rough roads. Summary of the Invention

Extending along the axis of the floating slide bar; rolling guide balls are rotatably mounted in the guide groove; a cross plate is fixed to the lower end of the floating slide bar; floating casters are installed at the lower end of the cross plate; the rear end of the extension rod is fixed to the bottom of the floating slide bar; the extension rods of the two retracting assemblies are arranged parallel and symmetrically; a treatment guide rod is fixed to the front end of the extension rod; the distance between the treatment guide rods of the two retracting assemblies gradually increases from one end closer to the support to the other end; a groove is provided on the inner side of the treatment guide rod, and guide steel balls are rotatably mounted in the groove; multiple guide steel balls are arranged in a linear array along the length of the groove; two limiting bolts are provided for the retracting assembly, which are fixed to both ends of the treatment guide rod to restrict the guide steel balls within the groove.

[0019] Preferably, the floating slide bar has at least two guide grooves; each guide groove contains at least two limiting steel balls.

[0020] Preferably, a set screw is installed on the floating assembly sleeve, with one end of the set screw abutting against the outside of the composite bearing.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The retraction assembly employs a structure combining a floating slide bar and a composite bearing. Smooth floating is achieved through the rolling of limiting steel balls within the guide groove, avoiding the wobbling problems caused by traditional external limiting plates with multiple hinge points and large gaps, thus reducing jamming during the traffic cone retraction process. Simultaneously, the guide steel ball inside the handling guide rod can rotate freely, minimizing frictional resistance when in contact with the traffic cone and eliminating inefficient sticking, resulting in smoother guiding and retraction of the traffic cone.

[0023] The cage-shaped pusher roller design of the pusher assembly has unique advantages: multiple push rods with curved sections are arranged in a circumferential array, forming a structure that is thinner in the middle and thicker at both ends. This structure not only guides the traffic cone to maintain an upright posture but also provides assistance through rotation driven by a motor. During rotation, the rubber coating on the outside of the push rod increases friction, while the curved section design, combined with the rotational motion, transforms the harmful frictional force generated by the relative sliding between the traditional pusher rod and the cone surface into the power to push and tip the cone. This is especially suitable for traffic cones made of softer materials or those that soften at high temperatures, effectively preventing them from bending and failing. In addition, the slight high-frequency vibration generated by the cage structure during operation can cause the tilted traffic cone to adjust its posture automatically, ensuring a stable pushing effect.

[0024] The device adjusts its overall height via a lifting assembly, and, in conjunction with the floating casters and sliding floating rods of the retractable assembly, automatically adapts to uneven road surfaces. When the road surface is uneven, the floating rod slides up and down along the composite bearing, ensuring a stable height difference between the handling guide rod and the push-down assembly and the ground. This avoids the handling failure problems caused by road surface fluctuations in traditional fixed devices, enabling the equipment to operate efficiently even in harsh environments such as undulating roads and potholes.

[0025] The internal limiting steel ball design of the retraction component replaces the multi-stage external limiting plates, simplifying the structure and reducing the size of the equipment; the positioning unit can quickly fix the position of the floating slide rod through the pin cylinder, improving the operation accuracy. These optimizations not only reduce equipment maintenance costs but also improve ease of operation, enabling the device to adapt to more scenarios (such as the recovery of low-center-of-gravity traffic cones and abnormally tilted traffic cones), significantly enhancing the practicality and industrialization potential of the equipment.

[0034] The invention will now be further described with reference to the accompanying drawings.

[0035] like Figures 1 to 6 As shown, a traffic cone retraction and knocking device includes:

[0036] The fixed frame 1 serves as the main support for the device; the fixed frame 1 is used to connect with the power equipment, for example, the fixed frame 1 is installed on the vehicle frame and used with the vehicle.

[0037] The lifting assembly, mounted on the fixed frame 1, includes a lifting seat 30 and a lifting hydraulic cylinder 27; the lifting seat 30 is slidably mounted on the fixed frame 1; the lower end of the lifting hydraulic cylinder 27 is hinged to the lifting seat 30, and the upper end is hinged to the fixed frame 1; the piston rod of the lifting hydraulic cylinder 27 extends and retracts, causing the lifting seat 30 to move up and down on the fixed frame 1.

[0038] The bracket 26 is hinged at one end to the lifting seat 30;

[0039] The luffing hydraulic cylinder 29 is hinged at one end to the lifting seat 30 and at the other end to the bracket 26; the extension and retraction of the piston rod of the luffing hydraulic cylinder 29 causes the bracket 26 to deflect in the horizontal plane.

[0040] A push-down assembly, mounted on bracket 26, is used to push down traffic cones;

[0041] Two retractable components are mounted on bracket 26 and are symmetrically arranged on both sides of the push-down component to retract the traffic cones toward the push-down component.

[0042] In this embodiment, a slide rail 31 is fixedly installed on the fixed frame 1; a slider 28 is fixedly installed on the lifting seat 30, and the slider 28 is slidably installed on the slide rail 31.

[0043] In existing equipment for recovering traffic cones, the vast majority of methods involve pushing or tilting the cones before recovery. Various manufacturers use crossbeams of different shapes to push the cones over. During this process, due to the relative displacement between the traffic cone and the push rod 24, the closely contacting push rod 24 generates a force that hinders the cone's tipping. (See attached...) Figure 3 During the process of pushing down the traffic cone, the distance between the contact point and the cone tip increases from L1 to L2, and there is mutual sliding. At this time, the traffic cone with a heavy base, low center of gravity and relatively soft cone body is easy to bend, causing the device to pass but the cone does not fall, resulting in abnormal recovery.

[0044] To solve the above-mentioned technical problems, in this embodiment, the pushing assembly includes a mounting base 25, a cage-shaped pushing roller 16, a drive motor 15, and a cooling fan 14; the mounting base 25 is fixed in the middle of the bracket 26; the drive motor 15 is fixed on the mounting base 25; the cooling fan 14 is installed at the rear end of the drive motor 15; a bearing seat 17 is fixedly provided on the mounting base 25; the cage-shaped pushing roller 16 includes multiple push rods 24 and two symmetrically spaced end plates 23; the push rods 24 are placed between the two end plates 23; the two ends of the push rods 24 are respectively fixedly connected to the two end plates 23; a connecting shaft is fixedly provided on the end plate 23; the connecting shaft is installed on the bearing seat 17; the axes of the connecting shafts of the two end plates 23 are on the same straight line; the output shaft of the drive motor 15 is connected to one of the connecting shafts; the multiple push rods 24 are arranged in a circular array with the axis of the connecting shaft as the center; an arc-shaped segment is integrally provided in the middle of the push rod 24, and the arc-shaped segment is bent towards the axis of the connecting shaft, forming a structure in which the cage-shaped pushing roller 16 is thin in the middle and thick at both ends. The drive motor 15 drives the cage-shaped pusher roller 16 to rotate, and the cooling fan 14 cools the drive motor 15.

[0045] In this embodiment, the push rod 24 is provided with an outer rubber coating to increase the coefficient of friction and facilitate pushing the traffic cone over when it comes into contact with it.

[0046] The cage-shaped pusher roller 16 rotates upward near the traffic cone, transmitting a large upward lifting force to the traffic cone through contact. At the same time, when the traffic cone and the cage-shaped pusher roller 16 are relatively displaced, the frictional resistance is minimized. Meanwhile, the design of the cage-shaped pusher roller 16, which is thinner in the middle and thicker at the end, guides the traffic cone to stand upright without tilting to the side. The cage structure of the cage-shaped pusher roller 16 generates slight high-frequency vibrations while pushing the cone, causing the tilted traffic cone to continuously adjust its posture during the vibration, maintaining the optimal standing position and posture.

[0047] Its beneficial effects are as follows: when the cage-shaped pusher roller 16 rotates in the forward direction, it eliminates the resistance generated by the relative displacement and converts it into assistance by means of high-speed rotation, making it suitable for traffic cones with softer materials and heavier bases. The shape of the cage-shaped pusher roller 16 can ensure that the posture of the traffic cone is relatively fixed, thereby greatly improving the work efficiency.

[0048] Traffic cone deployment and removal operations are based on road construction, so the road surface in the construction section will be uneven. Traditional traffic cone disposal devices are fixed to vehicles. When the road surface is uneven, the height difference between the disposal contact surface and the ground will fluctuate, leading to disposal failure. Construction on rough road surfaces is difficult.

[0049] To address the aforementioned issues, in this embodiment, the retractable assembly includes a floating slide bar 3, a floating combination sleeve 4, a baffle 6, a composite bearing 7, a limiting steel ball 8, a horizontal plate 21, floating casters 10, an extension rod 22, a handling guide rod 11, a guide steel ball 13, and a limiting bolt 12. The floating combination sleeve 4 is vertically fixed to the bracket 26. The composite bearing 7 is installed inside the floating combination sleeve 4. Two baffles 6 are provided, respectively fixed at both ends of the floating combination sleeve 4. The baffles 6 are provided with circular holes adapted to the floating slide bar 3. The floating slide bar 3 is slidably installed inside the composite bearing 7, with its end passing through the circular hole on the baffle 6 and extending to the outside of the floating combination sleeve 4. The composite bearing 7 is provided with a cavity to accommodate the guide steel ball 13. The mounting groove allows the limiting steel ball 8 to be rotatably mounted in the mounting groove of the composite bearing 7. The guide steel ball 13 and the mounting groove are clearance-fitted to ensure that the guide steel ball 13 can rotate within the mounting groove of the composite bearing 7. The diameter of the steel ball is denoted as D, the thickness of the composite bearing 7 is T, and the depth of the arc groove on the floating slide rod 3 is S, so D = T + S. A guide groove is provided on the outer surface of the floating slide rod 3, and the guide groove extends in a direction parallel to the axis of the floating slide rod 3. The guide groove and the guide steel ball 13 are clearance-fitted, and the limiting steel ball 8 is rotatably mounted in the guide groove. The horizontal plate 21 is fixed to the lower end of the floating slide rod 3. The floating caster 10 is installed at the lower end of the horizontal plate 21. The rear end of the extension rod 22 is fixed to the bottom of the floating slide rod 3.

[0050] In this embodiment, a floating limiting plate 2 is fixedly provided on the top of the floating slide bar 3; the diameter of the floating limiting plate 2 is larger than the diameter of the floating slide bar 3; a spring retaining ring 5 is fixedly provided on the baffle 6 at the upper end of the floating assembly sleeve 4, and the diameter of the floating limiting plate 2 is larger than the inner diameter of the spring retaining ring 5.

[0051] In this embodiment, a set screw 18 is installed on the floating assembly sleeve 4, and one end of the set screw 18 abuts against the outside of the composite bearing 7.

[0052] During assembly, the composite bearing 7 is installed into the floating assembly sleeve 4, and a baffle 6 and a spring retaining ring 5 are added. Axial positioning is achieved through the baffle 6. Then, the limiting steel balls are fixed in the mounting groove of the composite bearing 7 with grease. Next, the floating slide rod 3 is installed from bottom to top. After determining the direction, the set screw 18 is screwed in to tangentially position the composite bearing 7 and the floating assembly sleeve 4. Finally, the floating limiting plate 2 is installed to prevent any components from coming off. This allows the device to operate on rough roads while maintaining operational efficiency. The internal limiting steel balls 8 solve the problem of jamming by the external limiting mechanism on abnormally tilting cones. The mechanism is more compact, and the limiting effect is improved several times. Simultaneously, the rolling of the limiting steel balls 8 ensures smooth floating without any jamming, and the floating response is timely.

[0053] In existing devices, the figure-eight shaped handling guide rod 11 is widely used. To prevent jamming, a directional guide wheel is added to the contact side of the rod. However, abnormal forces often exerted on the traffic cone in the direction of the rotation axis of the guide wheel, causing jamming during the transfer of the traffic cone.

[0054] To address the aforementioned issues, the extension rods 22 of the two retractable components are arranged in parallel and symmetrical configurations; the disposal guide rod 11 is fixed to the front end of the extension rod 22; the distance between the disposal guide rods 11 of the two retractable components gradually increases from one end closer to the bracket 26 to the other end; a groove is provided on the inner side of the disposal guide rod 11, and the guide steel balls 13 are rotatably disposed in the groove; multiple guide steel balls 13 are configured and arranged in a linear array along the length of the groove; two limiting bolts 12 of the retractable components are configured and fixed to both ends of the disposal guide rod 11 respectively, for restricting the guide steel balls 13 within the groove, with a reserved gap to allow the steel balls to rotate in any direction, preventing obstruction of the traffic cone.

[0055] The optimal contact state between the handling rod and the traffic cone is contact without action, and the freely rotating guide steel ball 13 can play this role, which can minimize the transfer and jamming of the traffic cone; only limit bolts 12 need to be set at both ends of the handling rod slide, which reduces a lot of pin assembly work and greatly improves efficiency.

[0056] In this embodiment, the retracting assembly further includes a positioning unit; the positioning unit includes a pin cylinder 9, an L-shaped plate 19, a positioning plate 20, and a pin shaft; the L-shaped plate 19 is fixed on the floating assembly sleeve 4; the pin cylinder 9 is fixed on the L-shaped plate 19; the pin shaft is fixed on the piston rod of the pin cylinder 9; the positioning plate 20 is fixed on the floating slide rod 3; the positioning plate 20 is provided with a pin hole that matches the pin shaft.

[0057] In this embodiment, at least two guide grooves are provided on the floating slide bar 3; at least two limiting steel balls 8 are provided in each guide groove.

[0058] How to use

[0059] Installation and Fixing: Connect the fixing frame 1 to the power equipment (such as a vehicle frame) to ensure that the device moves stably with the power equipment.

[0060] Height adjustment: The lifting hydraulic cylinder 27 of the lifting component extends and retracts, causing the lifting seat 30 to slide up and down along the slide rail 31 of the fixed frame 1, thereby adjusting the overall height of the device to adapt to different road surfaces or traffic cone heights.

[0061] Angle adjustment: By extending and retracting the piston rod of the variable-amplitude hydraulic cylinder 29, the bracket 26 is driven to deflect in the horizontal plane, thereby adjusting the working angle of the pushing and retracting components.

[0062] Traffic cone retraction: Two symmetrical retraction components contact the traffic cone through the handling guide rod 11 (in a figure-eight shape, with the spacing gradually increasing from near to far) at the front end of the extension rod 22. The guide steel ball 13 (which can rotate freely) in the inner groove of the handling guide rod 11 reduces friction and retracts the traffic cone towards the middle push-down component.

[0063] Pushing down traffic cones: The drive motor 15 of the pushing component drives the cage-shaped pushing roller 16 to rotate (multiple push rods 24 with arc segments are arranged in a circumferential array). The rubber coating on the outside of the push rods 24 increases friction, and the traffic cone is pushed down by the assistance and slight vibration generated by the rotation. The cage structure can guide the traffic cone to maintain an upright posture and avoid tilting to the side.

[0064] Adapting to road surface undulations: The floating slide bar 3 of the retracting component can slide along the composite bearing 7 inside the floating assembly sleeve 4 (in conjunction with the limiting steel ball 8 and the guide groove), and in conjunction with the floating caster 10 contacting the ground, automatically adapting to road surface undulations to ensure handling stability.

[0065] Positioning and fixing: When necessary, the position of the floating slide rod 3 is fixed by the positioning unit (the pin cylinder 9 drives the pin shaft to insert into the pin hole of the positioning plate 20) to ensure the operation accuracy.
