Description

Technical Field

[0001] This utility model belongs to the field of highway maintenance technology, and specifically relates to a cone release and retrieval assembly for a cone release and retrieval device. Background Technology

[0002] Traffic cones, also known as road cones or cone-shaped road signs, are obstacles that block road traffic. They can be used as barriers or fences in case of traffic abnormalities. They are placed on roads, in dangerous areas, and in road construction sites to separate traffic flow and guide vehicle movement. For example, during highway maintenance, it is necessary to ensure the safety of vehicles and the work area. Therefore, traffic cones need to be placed outside the work area to guide vehicles safely. This is especially true when working on highways, where the speed of vehicles is high, making it even more necessary to place traffic cones to guide traffic.

[0003] In existing technologies, road cones are generally laid manually, that is, the road cones are laid on the road surface one by one by manual operation or collected one by one by manual operation. This method is not only inefficient in laying and collecting, but also results in the road cones being placed unevenly during the laying process. It is labor-intensive, has a low safety factor, and high labor costs.

[0004] Existing technologies also employ engineering vehicles used for highway maintenance to release and retrieve traffic cones. This involves stacking traffic cones in the cargo compartment of the engineering vehicle and transporting them along a designated route to a specific location for release and retrieval. For example, utility model application number 201821882572.7 discloses a "foldable, adaptive road surface automatic traffic cone release and retrieval device." This utility model uses a flipping mechanism to retrieve or release traffic cones from a cone sleeve. When in use, this utility model is mounted on a pickup truck, requiring a worker on the truck to place the traffic cones onto the cone sleeve of the flipping mechanism before the mechanism flips and releases the cones. When retrieving traffic cones, a worker is needed to remove the cones retrieved by the flipping mechanism and place them on the vehicle. Therefore, this utility model is a semi-automatic technology with a low level of automation.

[0005] Utility model application CN202021042118.8 discloses a "road cone deployment and retrieval device," belonging to the technical field of road traffic auxiliary equipment. It includes a deployment and retrieval assembly, a leveling assembly, a flatbed truck, an energy assembly, and a PLC control system. The deployment and retrieval assembly comprises a deployment and retrieval mounting frame, a vertical connecting rod, a horizontal connecting rod, and a rotating rod. The deployment and retrieval mounting frame is fixedly connected to the flatbed truck bed. One end of the vertical connecting rod is welded to one end of the horizontal connecting rod, and the other end of the horizontal connecting rod is hinged to the rotating rod. The rotating rod is driven to rotate by a drive assembly. When retrieving the road cone, as the flatbed truck moves, the horizontal rotating rod inserts into the cavity inside the road cone, then changes from a horizontal to a vertical position, transporting the road cone to the truck bed. Workers on the truck bed then neatly stack the road cones on the rotating rod inside the truck bed. When placing the road cones, workers on the truck bed place the stacked road cones onto the vertical rotating rod. The rotating rod then rotates from a vertical to a horizontal position, tilting the road cones onto the ground. This utility model also belongs to semi-automation technology, with a low level of automation.

[0006] The applicant has designed a highly automated traffic cone release and retrieval device. The device includes a frame on which a traffic cone storage bin and a working unit are installed. The working unit is equipped with a guide mechanism containing a blocking frame and a guide flow bar, and a traffic cone release and take-up roller conveyor containing a rigid chain lifting mechanism. In order to cooperate with the rigid chain lifting mechanism to sequentially place traffic cones onto the traffic cone release and take-up roller conveyor to achieve the release and retrieval of multiple traffic cones, a material distribution component is required. Existing technologies include solutions that use a cone gripper, such as the invention disclosed in application number CN201610209099.5, entitled "An Automatic Cone Retrieval and Deployment Machine for Disaster Relief." This invention collects cones through a cone collection mechanism, which includes a cone guide device and a cone gripping and lifting device. The cone gripping and lifting device includes a cone gripper connected to a cone clamping motor. The cone clamping motor controls the clamping and releasing of the cone gripper, and the cone lifting motor controls the lifting. By controlling the rotation of the cone lifting guide rail, the direction of the cone during collection is controlled. This invention has a large footprint and low efficiency, and cannot meet the needs of the cone release and retrieval device designed by the applicant. Utility Model Content

[0007] The problem to be solved by this utility model is to overcome the shortcomings and defects of the prior art and provide a road cone release and retrieval component that is space-saving and highly efficient, which is suitable for the needs of a road cone release and retrieval device designed by the applicant.

[0008] The technical solution adopted by this utility model includes a combined frame, a motor frame installed at the middle of the rear side of the combined frame, a servo motor installed in the motor frame, and first transmission shafts connected to the left and right sides of the servo motor via couplings. Second transmission shafts are respectively installed below the transmission mechanism mounting bases on the left and right sides of the combined frame. Four solenoid shafts are symmetrically installed on the transmission mechanism mounting bases on the left and right sides of the combined frame, and solenoid wheels are respectively installed at the lower ends of the four solenoid shafts. A right-angle gear transmission mechanism and a worm gear transmission mechanism are installed between the first transmission shafts and the solenoid shafts.

[0009] A first bevel gear is mounted on the first drive shaft on both the left and right sides, and a second bevel gear is mounted on the second drive shaft on both the left and right sides. The first bevel gear and the second bevel gear constitute a right-angle gear transmission mechanism. The rotational motion is transmitted from the first drive shaft to the second drive shaft through the meshing of the tooth surfaces of the first bevel gear and the second bevel gear. A first helical gear is mounted at the front and rear ends of the second drive shaft on both the left and right sides, and a second helical gear is mounted on four helical gear shafts. The first helical gear and the second helical gear mounted on the helical gear shaft constitute a worm gear transmission mechanism. The rotational motion is transmitted from the second drive shaft to the helical gear shaft through the meshing of the tooth surfaces of the first helical gear and the second helical gear.

[0010] The combined frame includes a rectangular base plate, with four columns connected at the four corners of the rectangular base plate by right-angle connectors. The bottom of the front and rear columns on the left and right sides are connected by connecting plates, and a transmission mechanism mounting base plate is connected to the top of the front and rear columns on the left and right sides. The coupling, the first transmission shaft, the second transmission shaft and the solenoid shaft are supported by the transmission mechanism mounting base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model adopts a spiral material distribution method, that is, on the combined frame, a servo motor, a right-angle gear transmission mechanism and a worm gear mechanism drive four spiral wheels to move diagonally synchronously, so that the road cone release and recycling mechanism can rotate synchronously, avoiding asynchronous jamming. (2) The combined frame of this utility model consists of a rectangular base plate, four columns, two connecting plates, and a transmission mechanism mounting base plate. It provides support for the coupling, the first transmission shaft, and the second transmission shaft, as well as for the solenoid axle. The mechanism is compact and stable. (3) When this utility model is used, it is used in conjunction with the hard chain lifting mechanism to realize the lifting and lowering of the traffic cone. It has a simple structure, occupies little space, is compact, runs smoothly, and is highly efficient and reliable. Attached Figure Description

[0014] like Figures 1-5As shown, the technical solution adopted by this utility model includes a combined frame 1, which includes a rectangular base plate 1-1. Four columns 1-2 are connected to the four corners of the rectangular base plate 1-1 by right-angle connectors. The bottoms of the front and rear columns 1-2 on the left and right sides are connected by connecting plates 1-3. A transmission mechanism mounting base plate 1-4 is connected to the top of the front and rear columns 1-2 on the left and right sides. A motor frame 2 is installed in the middle of the rear side of the combined frame 1, and a servo motor 3 is installed in the motor frame 2. Both sides of the servo motor 3 are connected by connecting plates 1-3. A first drive shaft 5 is connected via a coupling 4. The coupling 4 and the drive shaft 5 are supported by a transmission mechanism mounting base plate 1-4. A second drive shaft 10 is installed on the lower part of the transmission mechanism mounting base plate 1-4 on the left and right sides of the combined frame 1. Four solenoid shafts 6 are symmetrically installed on the transmission mechanism mounting base plates 1-4 on the left and right sides of the combined frame 1. A solenoid 7 is installed at the lower end of each of the four solenoid shafts 6. A right-angle gear transmission mechanism 9 and a worm gear transmission mechanism 8 are installed between the first drive shaft 5 and the solenoid shafts 6. Furthermore, a first bevel gear 9-1 is mounted on the first drive shaft 5 on both the left and right sides, and a second bevel gear 9-2 is mounted on the second drive shaft 10 on both the left and right sides. The first bevel gear 9-1 and the second bevel gear 9-2 constitute a right-angle gear transmission mechanism 9. Through the meshing of the teeth of the first bevel gear 9-1 and the second bevel gear 9-2, rotational motion is transmitted from the first drive shaft 5 to the second drive shaft 10. A first helical gear 8-1 (equivalent to a worm gear) is mounted at the front and rear ends of the second drive shaft 10 on both the left and right sides, respectively. A second helical gear 8-2 (equivalent to a worm) is mounted on four helical gear shafts 6. The first helical gear 8-1 (equivalent to a worm gear) and the second helical gear 8-2 (equivalent to a worm) mounted on the helical gear shafts 6 constitute a worm gear transmission mechanism 8. Through the meshing of the teeth of the first helical gear 8-1 and the second helical gear 8-2, rotational motion is transmitted from the second drive shaft 10 to the helical gear shafts 6. During operation, the servo... Motor 3 drives the first transmission shafts 5 on both sides to rotate in opposite directions via coupling 4. The first bevel gears 9-1 mounted on the first transmission shafts 5 on both sides rotate accordingly, driving the second bevel gears 9-2 mounted on the second transmission shafts 10 on both sides to rotate. This, in turn, drives the first helical gears 8-1 mounted on the front and rear ends of the second transmission shafts 10 on both sides to rotate. The four first helical gears 8-1 drive the four second helical gears 8-2 to rotate respectively. This achieves the servo motor 3 driving the first transmission shaft 5 via coupling 4, and the first transmission shaft 5 driving the four helical wheel shafts 6 to rotate in opposite directions in pairs via right-angle gear transmission mechanism 9 and worm gear transmission mechanism 8. This achieves the four helical wheels 7 rotating in opposite directions in pairs. When releasing the traffic cones, the servo motor 3 rotates forward, driving the four helical wheels 7 to rotate in opposite directions in pairs to achieve the release of individual traffic cones in a group. When retrieving the traffic cones, the servo motor 3 rotates in reverse, driving the four helical wheels 7 to rotate in opposite directions in pairs to achieve the retrieval of traffic cones in groups.

[0015] like Figures 6-13 As shown, in use, this utility model is mounted on the working part device 14 above the hard chain lifting mechanism 11-4 installed on the road cone take-up and drop roller conveyor 11 and through the combined frame 1. like Figure 7 and Figure 8 As shown, the road cone take-up and release roller conveyor 11 includes a roller frame 11-1. A horizontal roller assembly 11-2 and an inclined roller assembly 11-3 are installed on the horizontal surface of the roller frame 11-1. The horizontal roller assembly 11-2 and the inclined roller assembly 11-3 each have an electric roller assembly and a follower roller assembly. A notch is opened in the middle of the horizontal roller assembly 11-2. A hard chain lifting mechanism 11-4 and a gripper 11-5 are installed at the middle notch of the horizontal roller assembly 11-2 on the roller frame 11-1. like Figure 9 As shown, the working unit device 14 includes a frame consisting of a working unit support column 14-1, a working unit support top beam 14-2, and a working unit support bottom beam 14-3. The crossbeam of the working unit support top beam 14-2 extends to the left and is supported by a working unit support inclined column 14-4. Two sliding block seats 14-5 are installed on the working unit support top beam 14-2. Longitudinal moving sliding blocks 14-6 are installed below the left and right ends of the two sliding block seats 14-5 respectively. A sliding block moving motor 14-7 is also installed on the working unit support top beam 14-2. Driven by the sliding block moving motor 14-7... The working part device 14 is made to perform longitudinal linear reciprocating motion corresponding to the road cone storage belt conveyor 12-2 of the road cone warehouse 12; a telescopic belt conveyor 14-8 for transferring road cones is installed on the bottom beam 14-3 of the working part support; a vertical moving guide rail 14-9 of the working part is installed on the working part support column 14-1; furthermore, a front vertical moving guide rail of the working part for cooperating with the road cone receiving and discharging roller conveyor 11 is installed in front of the working part support column 14-1; a side vertical moving guide rail of the working part for cooperating with the guiding mechanism 13 is installed on the right side of the working part support column 14-1. like Figure 10As shown, the working unit 14 is installed on the right side of the traffic cone storage 12. More specifically, the working unit 14 is mounted on the longitudinal moving guide rails 12-3 installed on the left and right longitudinal beams of the top frame extending from the right side of the traffic cone storage 12. The traffic cone storage 12 includes 3-5 sets of ramp mounting supports 12-1 installed on a frame base for connection to a vehicle chassis. 3-5 horizontally placed traffic cone storage belt conveyors 12-2 are installed on top of the ramp mounting supports 12-1. Each traffic cone storage ramp conveyor 12-2 includes a traffic cone storage ramp 12-2-1, and each traffic cone storage ramp 12-2-1 can... The storage belt 12-2 has 3-5 rows, 7 compartments per row, and each compartment can hold a set of 12 traffic cones. The total storage capacity of the 3-5 horizontally placed traffic cone storage belts 12-2 is 200-400 cones, which can meet the needs of traffic cone release and retrieval for general highway maintenance. Although the traffic cone storage belt 12-2-1 is horizontally placed without any inclination, multiple traffic cone baffles 12-2-2 are fixed at intervals on the traffic cone storage belt 12-2-1, which are perpendicular to the conveying direction of the traffic cone storage belt 12-2. These traffic cone baffles 12-2-2 are used to prevent the traffic cones from moving around on the traffic cone storage belt 12-2, thus avoiding damage to the traffic cones. like Figures 11-13 As shown, the guiding mechanism 13 includes a double right-angle blocking frame 13-1, which is composed of an upper section 13-1-1, a middle section 13-1-2, and a lower section 13-1-3. A guide mechanism moving slider 13-2 that cooperates with the vertical moving guide rail on the side of the working part is installed on the left side of the upper section 13-1-1. A right-angle motor 13-3, a blocking frame 13-4, and a guide flow strip 13-5 are installed on the lower section 13-1-3. The right-angle motor 13-3 is used to drive the blocking frame 13-4 to flip and move the traffic cone onto the traffic cone collection and release roller conveyor. Furthermore, a rotating shaft 13-6 is installed on the left side of the lower section 13-1-3 of the double right-angle blocking frame, and a right-angle motor 13-3 is installed on the right side of the lower section 13-1-3 of the double right-angle blocking frame. The right-angle motor 13-3 includes a motor conical shaft 13-3-1. One side of the upper end of the blocking frame 13-4 is mounted on the rotating shaft 13-6, and the other end is mounted on the motor conical shaft 13-3-1 of the right-angle motor 13-3. The blocking frame 13-4 is locked to the motor conical shaft 13-3-1 and the rotating shaft 13-6 respectively by a pressure plate 13-7 and a locking nut 13-8. As a single unit, during operation, the motor conical shaft 13-3-1 of the right-angle motor 13-3 rotates. Since the blocking frame 13-4 is locked and fixed to both the motor conical shaft 13-3-1 and the rotating shaft 13-6, the rotation of the motor conical shaft 13-3-1 of the right-angle motor 13-3 simultaneously drives the blocking frame 13-4 and the rotating shaft 13-6 to rotate together. The flipping of the blocking frame 13-4 can guide the traffic cone onto the traffic cone collection and dispensing roller conveyor 11. The guide flow strip 13-5 is used to guide the traffic cone within the spatial range of the blocking frame 13-4 and to make contact with the blocking frame 13-4. To facilitate the pickup of traffic cones, the guide flow strips 13-5 are installed in a trumpet shape on the left and right sides of the lower section 13-1-3 of the double right-angle barrier. The opening angle is adjustable. Furthermore, the guide flow strips 13-5 are connected to the lower section 13-1-3 of the double right-angle barrier via hinges 13-9, which allows the guide flow strips 13-5 on the left and right sides to be folded and stored, reducing the space occupied by vehicles and avoiding damage in case of misoperation.

[0016] The lower end of the blocking frame 13-4 is provided with an arc-shaped blocking surface 13-4-1. Further, as... Figure 12 As shown, the blocking frame 13-4 includes a left upright 13-4-2, a right upright 13-4-3, an upper crossbar 13-4-4, and a U-shaped reinforcing rib 13-4-7 with a horizontal bottom and an opening on the right side, all welded together. A right hollow cylinder 13-4-5 and a left hollow cylinder 13-4-6 are respectively provided at the upper ends of the left upright 13-4-2 and the right upright 13-4-3. The blocking frame 13-4 is mounted on the rotating shaft 13-6 via the left hollow cylinder 13-4-6, and on the motor conical shaft 13 of the right-angle motor 13-3 via the right hollow cylinder 13-4-5. On -3-1, an arc-shaped blocking surface 13-4-1 is welded inside the opening on the right side of the U-shaped reinforcing rib 13-4-7. When releasing the traffic cone, the blocking frame 13-4 rotates counterclockwise under the drive of the right-angle motor 13-3, using the arc-shaped blocking surface 13-4-1 to stand the traffic cone upright. When retrieving the traffic cone, the blocking frame 13-4 rotates clockwise under the drive of the right-angle motor 13-3, gradually tilting the upright traffic cone during the reversing process. That is, during the flipping process, the blocking frame 13-4 gradually guides the traffic cone onto the traffic cone collection and release roller conveyor 11 and then gradually leaves the traffic cone, and the traffic cone returns to its vertical state.

[0017] In actual operation, the traffic cone storage 12 is connected to the chassis of the engineering vehicle used for highway maintenance. A guide mechanism 13 is installed on the working unit 14, which includes a telescopic belt conveyor 14-8 for transferring traffic cones, a blocking frame 13-4, and a guide flow bar 13-5. A touch screen for sending operation commands is installed in the driver's cab of the engineering vehicle. Its working process is as follows: When releasing the traffic cones, the engineering vehicle travels to the work section and stops at the starting point. The spacing and form of the released traffic cones are set on the touch screen and confirmed. The touch screen displays that preparation is complete and work can begin. The vehicle is started and travels at the prescribed speed and route. The traffic cone storage belt conveyor 12-2 and the telescopic belt conveyor 14-8 place groups (12 cones per group) of traffic cones onto this utility model. The hard chain lifting mechanism 11-4 rises and waits at the receiving position for this utility model to release the traffic cones. At this time, the servo motor 3 rotates forward, driving the four helical wheels 7 to rotate in opposite directions through the right angle gear transmission mechanism 9 and the worm gear transmission mechanism 8, sending the traffic cones to the hard chain lifting mechanism 11-4. The hard chain lifting mechanism 11-4 descends and places the traffic cones onto the traffic cone take-up and release roller conveyor 11. The horizontal roller group 11-2 and the inclined roller group 11-3 of the traffic cone take-up and release roller conveyor 11 rotate forward to release the traffic cones, thus placing them on the road surface. When retrieving traffic cones, first ensure the cones are upright on the road surface. Adjust the two guide rails 13-5 to their maximum opening. The driving route of the engineering vehicle should ensure the cones are drawn into the guide rails 13-5. Set and confirm the traffic cone retrieval option on the touchscreen. Under the push of the guide rails 13-5, the traffic cones on the road surface are guided onto the retrieval line. After the cones are blocked and tilted into place by the blocking frame 13-4, they are gradually moved from the inclined roller group 11-3 to the horizontal roller group 11-2 of the traffic cone retrieval roller conveyor 11. Guided above the rigid chain lifting mechanism 11-4, the blocking frame 13-4 passes over and leaves the traffic cone during rotation. The traffic cone naturally returns to an upright state due to the action of its center of gravity. At this time, the rigid chain lifting mechanism 11-4 rises and sends the traffic cone to the recycling position of this utility model. The servo motor 3 reverses, driving the four solenoid wheels 7 to rotate in opposite directions in pairs. This utility model picks up the traffic cones and packs them into groups (12 cones per group). Then, the telescopic belt conveyor 14-8 is used to transfer the traffic cones. The traffic cone storage ramp belt 12-2-1 reverses to put the traffic cones into storage.
