Description

Technical Field

[0001] The invention relates to the technical field of road construction and maintenance, and in particular to a fast placement and recovery device for traffic cones with stepless adjustment of storage size. Background Art

[0002] With the acceleration of urbanization and the continuous increase in traffic volume, the demand for traffic facilities in scenarios such as road construction, accident handling and temporary traffic control is growing. Traffic cones (also known as cones, ice cream cones) are a common temporary traffic sign and are widely used in road construction, accident scenes, lane closures and other occasions to guide vehicles and pedestrians and ensure traffic safety.

[0003] The traditional manual deployment and collection of traffic cones is inefficient, labor-intensive, and poses a major traffic safety hazard. The existing conventional semi-automatic traffic cone retracting device combines a mechanical device with a vehicle, such as installing a simple mechanical arm or a slide rail system at the rear of a truck. Although such devices can partially replace manual labor, they are slow to deploy and inefficient. In the scenario of rapid emergency rescue on urban roads, although the number of traffic cones to be deployed is effective, an extremely high deployment speed is required for rapid response. At the same time, manual intervention should be minimized to reduce personnel risks and traffic hazards. Summary of the invention

[0020] Furthermore, the recycling pretreatment mechanism includes an L-shaped bracket, a two-stage ball screw module, a motor, a driving wheel, a lifting platform, a straightening platform and a sensor;

[0024] The sensor is installed on a side of the boss away from the ball screw module, and the sensor is used to detect whether the angle and orientation of the traffic cone placed on the rotation platform meets the required alignment requirement.

[0025] Beneficial effects of the present invention:

[0026] 1. The linear module of the flipping and translating guide rail mechanism of the present invention can drive the traffic cone storage box, the clamping mechanism, and the side sliding guide rail to move in the left and right directions of the frame, so that the traffic cone retracting and releasing mechanism can place traffic cones at different positions and the clamping mechanism can grab traffic cones at different positions. The electric push rod of the flipping and translating guide rail mechanism can drive the traffic cone storage and placement mechanism to flip 0-90°, and the base has a platform for supporting the traffic cone storage and placement mechanism; the side sliding guide rail of the traffic cone storage and placement mechanism can be unfolded and recovered; the L-shaped bracket of the recovery pretreatment mechanism can move forward and backward along the frame, and can be retracted under the vehicle when not working. The design of the above three mechanisms saves the space occupied by the vehicle body in the non-working state, improves the driving safety of the engineering vehicle, satisfies the self-locking function of the device, and plays a protective role for the device.

[0027] 2. The bidirectional ball screw of the flipping and translational guide rail in the present invention drives the two sub-boxes of the traffic cone storage box to move relative to each other to achieve the opening and closing effect, thereby changing the storage width of the traffic cone storage box; the limiting mechanism in the traffic cone storage and placement mechanism can push the limiting plate through the three-axis cylinder to achieve the telescopic effect and change the storage depth of the traffic cone storage box; the two cooperate to meet the needs of storing traffic cones of different sizes and ensure that the traffic cone stack will not collapse or move in the storage box.

[0028] 3. When multiple traffic cones are placed in a straight line, the landing point of the traffic cones must exceed the width of the vehicle body. By setting a side sliding guide rail, which is a three-link mechanism for easy deployment and recovery, the traffic cones can slide along the side sliding plate to the required landing point, which can meet various deployment needs of traffic cones.

[0029] 4. The clamping mechanism of the traffic cone storage and placement mechanism of the present invention is composed of three mechanical arms and clamps, which can meet the pitch and rotation requirements; installing the mechanical arms on the traffic cone storage box can solve the need for horizontal lateral displacement of the mechanical arms, and installing mechanical arms on both sides of the traffic cone storage box can grab traffic cones located on the left and right.

[0030] 5. The straightening mechanism of the recycling pretreatment mechanism of the present invention can adjust the traffic cone to a state to be recycled; when directly recycling, the traffic cone chassis is prevented from being stuck at the two cylindrical gears due to the mismatch between the distance between the two cylindrical gears in the retracting mechanism and the length of the traffic cone chassis, thereby ensuring the stability of the traffic cone recycling process.

[0031] 6. The lifting platform in the present invention realizes the lifting function by a two-stage ball screw module. This two-stage structure not only saves space when retracted and is not easy to interfere with other mechanisms, but also can achieve the lifting height requirements of the lifting platform.

[0032] 7. The number of teeth on the driving wheel of the straightening platform in the present invention is less than that on the driven wheel, which is more conducive to controlling the straightening angle of the straightening platform. The straightening platform is a hollow circular table, which can not only reduce the weight of the mechanism, but also ensure that the traffic cone grabbed by the robot arm can remain concentric with the center of the straightening platform.

[0033] 8. The sensor uses a laser sensor or an infrared sensor. Since the outer contour of the traffic cone chassis is a polygon, when the shortest side of the polygon from the center is parallel to the detection signal and almost coincides with the detection signal, the traffic cone is in a state to be recycled. When the shortest side of the polygon from the center is not parallel to the detection signal, the chassis will interfere with the detection signal, and the system will recognize that the traffic cone is not in a state to be recycled, and the rotation platform needs to be rotated. This method can effectively determine whether the traffic cone is in a straightened state to be recycled, and the detection method is simple and reliable.

[0034] 9. The distance between the inner sides of the two supporting thin rods of the lifting platform of the present invention is greater than the maximum outer diameter of the rotation platform and less than the distance between the two longest opposite sides of the traffic cone chassis; this design can enable the rotation platform to drive the traffic cone to rotate through friction, and the lifting platform can drive the traffic cone to rise, without interference between the rotation platform and the lifting platform, and the supporting thin rods will not interfere with other structures during the lifting and movement process.

DETAILED DESCRIPTION

[0055] The present invention will now be described in further detail with reference to the accompanying drawings.

[0056] The invention discloses a fast placing and recovering device with stepless adjustment of the storage size of traffic cones.

[0057] For ease of understanding, the vehicle's forward direction is defined as forward, facing forward, the right side is the right side; the bottom is the bottom surface; clockwise rotation is positive rotation; counterclockwise rotation is reverse rotation.

[0058] Reference Figures 1 to 4 A fast placement and recovery device with stepless adjustment of the storage size of traffic cones comprises a base vehicle 1, a flipping and translational guide rail mechanism 2, a traffic cone storage and placement mechanism 3 and a recovery pretreatment mechanism 4. The flipping and translational guide rail mechanism 2 is installed on the base vehicle 1, and the output end of the flipping and translational guide rail mechanism 2 is connected to the traffic cone storage and placement mechanism 3, which can drive the traffic cone storage and placement mechanism 3 to translate and flip, and change the position and posture of the traffic cone storage and placement mechanism 3; the recovery pretreatment mechanism 4 is installed at the bottom of the rear end of the base vehicle 1, and the recovery pretreatment mechanism 4 is used to adjust the angle and orientation of the traffic cone; after the recovery pretreatment mechanism 4 adjusts the traffic cone to the required angle and orientation, the traffic cone is sent to the inside of the traffic cone storage and placement mechanism 3.

[0059] Reference Figures 5 to 7The flipping and translation guide mechanism 2 includes a linear module 21, a moving block 22, a bidirectional ball screw 23, a base 24 and an electric push rod 25. The linear module 21 can adopt any one of a ball screw mechanism, a synchronous belt mechanism, a gear rack mechanism, a chain drive or a pneumatic mechanism, as long as it can achieve linear movement. The linear module 21 is fixedly mounted on the upper end surface of the tail of the base vehicle 1. The moving block 22 is mounted on the moving output end of the linear module 21 as a moving part of the linear module 21; the moving block 22 can move horizontally left and right along the tail of the base vehicle 1 through the linear module 21. Two bidirectional ball screw mechanisms 23 are provided, and the bottoms of the two bidirectional ball screw mechanisms 23 are fixedly mounted on the moving block 22, and the two bidirectional ball screw mechanisms 23 are kept parallel and aligned, and can be displaced synchronously with the moving block 22.

[0060] There are two bases 24, and the two ends of the bottom of the base 24 are connected to the moving output ends of the two bidirectional ball screw mechanisms 23. The two bases 24 are kept parallel and aligned, and the two bases 24 can be relatively close to and away from each other through the bidirectional ball screw mechanism 23. There are two electric push rods 25, which correspond to the bases 24 one by one; the tail of the electric push rod 25 is hingedly installed on the corresponding base 24.

[0061] When the linear module 21 is working, the moving block 22 moves horizontally left and right along the tail of the base vehicle 1. Since the bidirectional ball screw mechanism 23 is installed on the moving block 22, the bidirectional ball screw mechanism 23 and the base 24 thereon can move horizontally left and right along the tail of the base vehicle 1; when the bidirectional ball screw mechanism 23 is working, the two bases 24 located above it make relative motion, which can then satisfy the opening and closing motion of the traffic cone storage box 31 described below.

[0062] Reference Figures 7 to 14 The traffic cone storage and placement mechanism 3 includes a traffic cone storage box 31, a traffic cone retracting and releasing mechanism 32, a box shell 33, a guide rail 34, a slider 35, a clamping mechanism 36, a side sliding guide rail 37 and a limit mechanism 38. The traffic cone storage box 31 is divided into two sub-boxes 311, and the bottom of each sub-box 311 close to the base vehicle 1 is hinged to the base 24, and the end of the electric push rod 25 away from the base 24 is hinged to the outer wall of the sub-box 311.

[0063] The box shell 33 is located at one end of the traffic cone storage box 31 away from the flipping and translation guide rail mechanism 2. Four sliders 35 are fixed to the outer wall of the traffic cone storage box 31 close to the box shell 33. Two sliders are correspondingly arranged on each sub-box 311, and the sliders 35 on the sub-box 311 are kept flush. Two rows of guide rails 34 adapted to the sliders 35 are fixed to the inner side of the box shell 33. The guide rails 34 are inserted into the sliders 35 of the two sub-boxes 311, and the sub-boxes 311 and the box shell 33 are slidably connected through the sliders 35 and the guide rails 34.

[0064] The traffic cone retracting and releasing mechanism 32 includes a driving motor 321, a cylindrical gear 322 and a bearing seat 323; the output shaft of the driving motor 321 is fixed coaxially with the cylindrical gear 322, and the driving motor 321 drives the cylindrical gear 322 to rotate; the driving motor 321 and the cylindrical gear 322 are installed at the bottom of the inner wall of the traffic cone storage box 31 through two bearing seats 323; the tooth surface of the cylindrical gear 322 is designed to be uneven to increase the friction of the traffic cone chassis on the upper side. The rotation angle of the driving motor 321 each time is the angle of two adjacent gears of the cylindrical gear 322.

[0065] Reference Fig.15 The clamping mechanism 36 includes a first arm 361, a second arm 362, a third arm 363 and a clamping claw 364. The first arm 361 is fixedly mounted on the side of the traffic cone storage box 31, one end of the second arm 362 is hinged to the first arm 361 through a pitch joint, and the other end of the second arm 362 is hinged to the third arm 363 through a rotation joint. The clamping claw 364 is mounted on the end of the third arm 363 away from the second arm 362, and the clamping claw 364 can be opened and closed by a motor 43 driven mechanical structure, a pneumatic structure or a hydraulic structure.

[0066] Reference Fig.11 and Fig.12 The side sliding guide 37 is located outside the traffic cone storage box 31, and the side sliding guide 37 includes a support rod 371, a movable slider 372, a linear guide 373, a side slide 374, a first connecting rod 375, and a second connecting rod 376. One end of the support rod 371 is installed on the outer wall of the traffic cone storage box 31, and the other end is connected to the linear guide 373. In order to avoid interference between the side sliding guide 37 and other parts, the support rod 371 is designed as a multi-bend part extending outward. There are two movable sliders 372, and the two movable sliders 372 move on the linear guide 373, and are respectively controlled and driven by different telescopic cylinders or motors 43.

[0067] One end of the first link 375 and one end of the second link 376 are respectively hinged to the two moving sliders 372 through a rotating joint, and the first link 375 and the second link 376 can rotate clockwise or counterclockwise around the moving slider 372 through the rotating joint, and the other end of the first link 375 and the second link 376 away from the moving slider 372 is hinged through the rotating joint. The side slide 374 is fixedly connected to the first link 375, and the length of the side slide 374 is about twice the length of the first link 375.

[0068] Reference Fig. 9 and Fig.10The limiting mechanism 38 includes two three-axis cylinders 381 and a limiting plate 382; the two three-axis cylinders 381 are located at the upper end of the traffic cone retracting and releasing mechanism 32 and are installed on the inner wall of the traffic cone storage box 31. One end of the limiting plate 382 is fixedly installed on the push rod of the three-axis cylinder 381, and moves with the extension and retraction of the push rod of the three-axis cylinder 381. The end surface of the limiting plate 382 away from the three-axis cylinder 381 is adapted to the polygonal outer contour of the traffic cone chassis.

[0069] When the electric push rod 25 is extended or shortened, the traffic cone storage box 31 can be turned over accordingly; when in working state, the electric push rod 25 is shortened and the traffic cone storage box 31 is perpendicular to the ground; when in non-working state, the electric push rod 25 is extended and the traffic cone storage box 31 is parallel to the ground. Since the bidirectional ball screw mechanism 23 is connected to the moving block 22 on the linear module 21, the moving block 22 translates and drives the traffic cone storage box 31 to translate, and the traffic cone storage and placement mechanism 3 can place and or recycle traffic cones at different positions.

[0070] Since the base 24 is connected to the bidirectional ball screw 23, and the guide rail 34 and the slider 35 are connected between the traffic cone storage box 31 and the box shell 33, when the base 24 moves bidirectionally with the bidirectional ball screw 23, the traffic cone storage box 31 can be driven to open and close. The limit plate 382 can support the traffic cone stack under the effect of the extension of the three-axis cylinder 381. The bidirectional ball screw 23 and the limit mechanism 38 play the role of limiting the traffic cone stack in width and depth in the traffic cone storage box 31, which not only meets the needs of storing traffic cones of different sizes, but also plays the role of fixing the traffic cone stack.

[0071] In the process of retrieving traffic cones, the left and right displacement of the clamping mechanism 36 is controlled by the traffic cone storage and placement mechanism 3; when the vehicle is moving backward, the clamping mechanism 36 clamps the traffic cone and places it in the recycling pre-processing mechanism 4. In the process of placing traffic cones, the left and right displacement of the traffic cone storage box 31 is controlled by the linear module 21, and the traffic cone storage and placement mechanism 3 is controlled to place traffic cones at different landing positions. The traffic cone retracting and releasing mechanism 32 is an actuator for retracting and releasing traffic cones; when placing traffic cones, the traffic cone at the bottom of the traffic cone stack is pushed out by rotating the cylindrical gear 322 through the driving motor 321; when retracting traffic cones, the traffic cone is pushed into the traffic cone stack by rotating the cylindrical gear 322 in the opposite direction.

[0072] When placing traffic cones in a straight line, the point where the traffic cones land needs to be on the left side of the vehicle body. The linear module 21 moves the traffic cone storage and placement mechanism 3 to the far left. The two moving sliders 372 in the side sliding mechanism first slide down at the same speed. When the side slide plate 374 slides down to a certain position, the moving slider 372 on the top accelerates to slide down, and because there is a rotating pair between the first connecting rod 375 and the second connecting rod 376, the side slide plate 374 is unfolded and tilted to the left until the moving slider 372 on the bottom reaches the bottom of the linear guide 373. Then the driving motor 321 is started to drive the cylindrical gear 322 to rotate, and the traffic cone at the bottom of the traffic cone pile is pulled out, and slides to the left side of the vehicle through the side sliding guide plate. Repeat the above steps to complete the continuous delivery. Changing the operation direction can realize the demand of delivering traffic cones to the right side of the vehicle. When the side slide plate 374 is recovered, the motion state of the two moving sliders 372 is opposite to the motion state when the side slide plate 374 is unfolded. During the process of diagonally placing the traffic cones, the traffic cone storage and placement mechanism 3 moves the moving slider 372 connected to the mechanism and simultaneously rotates the cylindrical gear 322 in opposite directions, thereby achieving the diagonal placement of the traffic cones.

[0073] The delivery speed can be adjusted according to the vehicle speed and the specified cone spacing requirements. The adjustment formula is:

[0074]

[0075] Wherein, t is the time interval for placing traffic cones, in seconds;

[0076] L is the required cone spacing, in m;

[0077] v is the current vehicle speed in m / s;

[0078] h is the height of the traffic cone from the ground, in meters;

[0079] g is the acceleration due to gravity, and its unit is m / s.

[0080] Reference Figures 15 to 19The recycling pretreatment mechanism 4 includes an L-shaped bracket 41, a two-stage ball screw module 42, a motor 43, a driving wheel 44, a lifting platform 45, a straightening platform 46 and a sensor 47. The upper end of the L-shaped bracket 41 is installed at the bottom of the tail end of the base vehicle 1, and can move along the forward and backward direction of the base vehicle 1. The two-stage ball screw module 42 includes a first screw module 421 and a second screw module 422, and both are installed on the L-shaped bracket 41. Among them, the first screw module 421 is fixedly installed at the midline position of the outer wall of the vertical plate body of the L-shaped bracket 41, and the second screw module 422 is installed at the moving output end of the first screw module 421, serving as a moving part of the first screw module 421. The lifting platform 45 is installed at the moving output end of the second screw module 422 and serves as the moving part of the second screw module 422; the lifting platform 45 is formed with parallel supporting thin rods 451 on both sides away from one end of the second screw module 422, and the lifting platform 45 lifts the traffic cone through the supporting thin rods 451 and sends the traffic cone to the traffic cone retracting mechanism 32 in the traffic cone storage box 31.

[0081] A boss 411 is fixed on the upper surface of the horizontal plate of the L-shaped bracket 41. A driven wheel 412 is rotatably connected to the boss 411 through a bearing. The driving wheel 44 is meshed with the driven wheel 412. The driving wheel 44 is coaxially fixed with the output shaft of the motor 43. The motor 43 provides a rotational driving force for the driving wheel 44. The number of teeth of the driven wheel 412 is greater than that of the driving wheel 44. The straightening platform 46 is a truncated cone that fits the inner cavity at the bottom of the traffic cone. The straightening platform 46 is fixedly installed on the top of the driven wheel 412. Then the motor 43 drives the driven wheel 412 to rotate through the driving wheel 44, and the angle and orientation of the straightening platform 46 can be adjusted. The distance between the inner sides of the two supporting thin rods 451 of the lifting platform 45 is greater than the maximum outer diameter of the straightening platform 46 and less than the distance between the two longest opposite sides of the traffic cone chassis, so as to ensure that the supporting thin rods 451 can lift the traffic cone to avoid interference. The sensor 47 is installed on the side of the boss 411 away from the ball screw module 42. The sensor 47 can be a laser sensor 47 or an infrared sensor 47. The sensor 47 is used to detect whether the angle and orientation of the traffic cone placed on the rotation platform 46 meets the required alignment requirements.

[0082] When not in operation, the L-shaped bracket 41 is retracted at the bottom of the inner rear of the base vehicle 1; when the traffic cone is recovered, the L-shaped bracket 41 extends from the bottom of the rear of the base vehicle 1, and the clamping mechanism 36 places the captured traffic cone on the rotation platform 46 on the L-shaped bracket 41. The traffic cone cover is arranged outside the rotation platform 46, and the center line of the traffic cone coincides with the center line of the rotation platform 46 to avoid the misalignment of the traffic cone. When the traffic cone is on the rotation platform 46, the sensor 47 detects the angle and orientation of the traffic cone chassis. Since the outer contour of the traffic cone chassis is a polygon, when the shortest side of the polygon of the traffic cone chassis from the center is parallel to the detection signal of the sensor 47 and almost coincides with the detection signal, the traffic cone is in a state to be recovered. When the shortest side of the polygon from the center is not parallel to the detection signal of the sensor 47, the traffic cone chassis will block the detection signal of the interference sensor 47, and the system recognizes that the traffic cone is not in a state to be recovered, and it is necessary to rotate the rotation platform 46 to adjust the orientation of the traffic cone. At this time, the motor 43 drives the driving wheel 44 to rotate, the driving wheel 44 drives the driven wheel 412 to rotate, the driven wheel 412 drives the rotation platform 46 to rotate, and the rotation platform 46 drives the traffic cone on it to rotate through friction, so that the traffic cone is rotated to the required angle and orientation, so that the chassis of the traffic cone does not block the signal of the interference sensor 47. When the traffic cone is in the rotation and recovery state, the two ball screw modules 42 drive the lifting platform 45 to move upward, and the supporting thin rod 451 sends the traffic cone to the cylindrical gear 322 of the traffic retracting mechanism. Repeat the above process to complete the traffic cone recovery task.

The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
