Description

Technical Field

[0001] The invention relates to the field of daily road maintenance engineering equipment, in particular to a device for collecting and placing traffic cones. Background Art

[0002] Traffic cones are devices that are often used in daily maintenance of traffic roads. During use, a continuous roadblock structure is formed by continuously placed traffic cones, thereby playing the role of separating road surface areas. At present, the placement and recovery of traffic cones are carried out by 2 to 3 construction workers at the rear of road engineering vehicles along specific routes of highways. This manual operation method has slow operation speed, low safety factor, and inconsistent placement intervals of traffic cones.

[0003] In recent years, those skilled in the art have focused on the research and development of automatic traffic cone retracting and releasing devices. The main technical solution structure of the traffic cone retracting and releasing equipment in the prior art mainly includes a toggle crossbar and a rotating swing arm set on one side of a traffic vehicle such as a truck, and a cone positioning piece is set at the end of the rotating swing arm. During the placement of the traffic cone, the traffic vehicle travels along the traffic cone placement route, and the staff on the vehicle places the traffic cone on the cone positioning piece. The rotating swing arm swings to place the traffic cone on the bottom surface, and then the toggle crossbar swings the traffic cone to an upright state. During the recycling process, on the contrary, the toggle crossbar pushes the traffic cone to one side, and the rotating swing arm can hook the traffic cone dumped on the road surface during the rotation of the cone positioning piece. The rotating swing arm continues to rotate to lift the traffic cone to a certain height, so as to facilitate the staff on the vehicle to grab the traffic cone and realize the recycling of the traffic cone.

[0004] The existing technical solutions can improve the efficiency of traffic cone collection and release to a certain extent, but the rotating swing arm can only handle one traffic cone at a time. It is necessary to complete the hooking or placing action of the traffic cone and the lifting action of the traffic cone at the same time. The two actions need to be completed continuously, which increases the time consumption of each placement or collection action and limits the work efficiency. In addition, the speed of the traffic vehicle also needs to match the action rate of the rotating swing arm, which increases the difficulty of operation and further limits the improvement of work efficiency. Summary of the invention

[0005] The present invention aims to overcome the above-mentioned shortcomings of the automatic traffic cone retracting and releasing device in the prior art and to provide a traffic cone retracting and releasing device which can effectively improve the efficiency of placing and recovering traffic cones and improve safety.

In this way, during the process of placing the traffic cone, the staff can place the next traffic cone without waiting for the pallet to rise to the right position. After the pallet rises, the movable stopper flips downward to allow the traffic cone to fall on the pallet, which is then transported to the cone placement device at the bottom by the pallet.

DETAILED DESCRIPTION

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] Such as 1. Figure 2 As shown, a traffic cone storage and releasing device of the present invention includes a mounting bracket 1 and a toggle crossbar, and also includes a cone lifting device 2 and a cone placing device 3, wherein the cone lifting device 2 includes a lifting mechanism and a tray 201, and the lifting mechanism drives the tray 201 to carry the traffic cone 6 to lift and lower; the cone placing device 3 is arranged at the bottom of the lifting device, and the cone placing device 3 includes a cone positioning piece 301 and a flipping mechanism, and the flipping mechanism drives the cone positioning piece 301 to flip; the tray 201 is provided with an avoidance gap 202 for accommodating the cone positioning piece 301, and when the tray 201 descends to the bottom of the lifting mechanism, the flipping mechanism drives the cone positioning piece 301 to flip toward one side of the lifting mechanism to place the traffic cone on the cone positioning piece 301 on the tray 201, or drives the cone positioning piece 301 to flip toward the road side to place the traffic cone on the tray 201 on the road, and the mounting bracket 1 is used to install the device on the side of the traffic vehicle.

[0046] The cone positioning member 301 has a cone shape that matches the inner cavity of the traffic cone, and a support plate 302 that supports the bottom surface of the traffic cone is disposed at the bottom of the cone positioning member 301 .

[0047] The flipping mechanism includes a flipping frame 303, a flipping shaft 304 and a rotation driving mechanism. The flipping frame 303 is arranged at one end of the lifting mechanism close to the road surface. The cone positioning member 301 is rotationally connected to the flipping frame 303 through the flipping shaft 304. The flipping frame 303 is provided with a rotation driving mechanism for driving the flipping shaft 304 to rotate.

[0048] The rotation drive mechanism includes a first push rod motor 305, a driving rack 306 and a driven gear 307. The driven gear 307 is sleeved on the flip shaft 304. The driving rack 306 is slidably connected to the flip frame 303. The first push rod motor 305 drives the driving rack 306 to slide relative to the flip frame 303. The driving rack 306 engages with the driven gear 307. When the driving rack 306 slides, it drives the flip shaft 304 to rotate through the driven gear 307. The flip shaft 304 drives the cone positioning member 301 to swing toward the road side or toward the lifting mechanism side.

[0049] The first push rod motor 305 drives the driving rack 306 to slide. Since the driving rack 306 and the driven gear 307 are engaged, the driven gear 307 can be driven to cause the cone positioning member 301 on the flip shaft 304 to flip, thereby placing the traffic cone on the tray 201 on the road surface, or placing the traffic cone on the tray 201.

[0050] The cone placing device 3 also includes a pair of parallel guide frames 4, which are arranged on the side of the flip mechanism facing the road surface, and two toggle cross bars are arranged between the guide frames 4, wherein the first toggle cross bar 401 can toggle the top edge of the chassis of the traffic cone tilted on the road surface when the traffic vehicle moves, so that the traffic cone stands upright; the second toggle cross bar 402 is higher than the first toggle cross bar 401, and the second toggle cross bar 402 can toggle the top of the traffic cone standing upright on the road surface when the traffic vehicle moves, so that the traffic cone falls down.

[0051] The lifting mechanism includes a lifting guide rail 203 and a lifting drive mechanism. The lifting drive mechanism drives the tray 201 to slide up and down along the lifting guide rail 203.

[0052] The lifting drive mechanism includes a servo motor 204, a conveyor belt 205, a conveyor pulley 206, a sliding seat 207 and a position sensor 208. A conveyor pulley 206 and a position sensor 208 are respectively provided at the upper and lower ends of the lifting guide rail 203. The conveyor belt 205 bridges two conveyor pulleys 206. The sliding seat 207 is slidably connected to the lifting guide rail 203. The sliding seat 207 is fixedly connected to the conveyor belt 205. The tray 201 is connected to the sliding seat 207. The servo motor 204 drives the conveyor pulley 206.

[0053] The position sensor 208 can detect the positions of the pallet 201 and the traffic cones on the pallet 201 , thereby controlling the pallet 201 to be lifted or lowered along the lifting rail 203 .

[0054] The top of the cone lifting device 2 is provided with a movable stopper 5 that can be turned relative to the lifting mechanism. The tray 201 is provided with an escape opening 209 that can accommodate the movable stopper 5 at one end close to the lifting guide rail 203. The movable stopper 5 can be set as a movable stopper plate or a movable stopper rod as needed.

[0055] The number of the movable limiting members 5 is set to two, and the movable limiting members 5 are rotatably connected to the lifting mechanism. The lifting mechanism is rotatably connected to a second push rod motor 501 on one side of the movable limiting member 5. A connecting rod 502 is provided between the second push rod motor 501 and the movable limiting member 5. The second push rod motor 501 drives the movable limiting member 5 to flip relative to the lifting mechanism. When the movable limiting member 5 is flipped to a horizontal position, it is used to support the traffic cone. When the movable limiting member 5 is flipped to a vertical position, the traffic cone slides downward.

[0056] The movable stopper 5 can be turned to a horizontal position to temporarily place a traffic cone. In this way, during the process of placing the traffic cone, the staff can place the next traffic cone without waiting for the tray 201 to rise to the right position. After the tray 201 rises, the movable stopper 5 turns downward to make the traffic cone fall on the tray 201, and then the tray 201 transports the traffic cone to the cone placement device 3 at the bottom. At the same time, since the traffic cone is large in size, there is no need to wait for the tray 201 to rise to the top of the lifting mechanism, and the movable stopper 5 can lower the traffic cone, which can effectively shorten the lifting stroke of the tray 201 and greatly improve work efficiency.

[0057] The mounting bracket 1 includes a main bracket 101, a hanging bracket 102 and a screw positioning piece. The cone lifting device 2 is arranged on the main bracket 101. One end of the hanging bracket 102 is connected to the main bracket 101, and a plurality of positioning plates 103 are arranged on the other end. The positioning plate 103 is provided with a screw positioning piece. The screw positioning piece includes a positioning screw 104, a rotating handle 105 and a positioning foot pad 106. The positioning screw 104 is horizontally threadedly connected to the positioning plate 103. The positioning foot pad 106 is arranged at the end of the positioning screw 104 close to the main bracket 101, and the rotating handle 105 is arranged at the end of the positioning screw 104 away from the main bracket 101.

[0058] like Figure 3 As shown, the present application completes the automatic traffic cone retracting and releasing work through the cooperation of the cone lifting device 2 and the cone placing device 3. The device is suspended on one side of the traffic vehicle and moves along with the traffic vehicle.

[0059] like Figure 5-10In the dynamic process of placing traffic cones shown, the staff places the traffic cones on the pallet 302, which is transported to the bottom by the lifting mechanism, and the traffic cones are placed on the cone positioning member 301. The cone positioning member 301 is flipped to the side of the road surface by the flipping mechanism, and the traffic cones are placed on the road surface. The first toggle crossbar 401 toggle the upper edge of the traffic cone chassis to swing the traffic cone to an upright state, and the work is cyclically completed in sequence to complete a series of traffic cone placement work. At the same time, the two movable limit members 5 can temporarily support the traffic cones 6, and the staff can place the next traffic cone without waiting for the tray 201 to rise to the position. After the tray 201 rises, the movable limit member 5 flips downward, so that the traffic cone falls on the tray 201, thereby reducing the rising stroke of the tray 201 and further improving efficiency.

[0060] Similarly, if Figure 11-16 In the dynamic process of the traffic cone recovery process shown, the second toggle crossbar 402 first dumps the traffic cone, and after the cone positioning member 301 extends into the inner cavity of the traffic cone, the flipping mechanism flips the cone positioning member 301 to the side of the lifting mechanism, and the traffic cone is placed on the tray 201. The tray 201 is lifted by the lifting mechanism to a height that the staff can grab, and the traffic cone recovery work is completed in a cycle. After the tray 201 rises to the top, the two movable limit members 5 temporarily support the traffic cone 6, which is convenient for the operator to grab. At this time, the tray 201 can be lowered to lift the next traffic cone. The solution of the present application separates the action of the traffic cone hooking / placing mechanism and the traffic cone height lifting mechanism. During the lifting or lowering process of the previous traffic cone, the cone placing device 3 can synchronously place or hook the traffic cone, thereby reducing work time and improving work efficiency.

[0061] like Figure 5 As shown, the mounting bracket 1 can be set on both sides of the transportation vehicle 7, usually a truck cargo bag. The screw positioning member is clamped to the side wall of the truck cargo bag by rotating the handle 105 to achieve quick installation. The device can be set on the left or right side of the truck according to the on-site requirements, so that the traffic cones can be retracted and released in the direction of the truck's advance. After the traffic cones are retracted and released, the mounting bracket can be hung behind the truck cargo bag, and the guide frame can be disassembled and installed vertically on the main bracket. In this way, the equipment can be transported quickly without affecting the normal and safe driving of the transportation vehicle.
