Description

Technical Field

[0001] The invention relates to the technical field of road construction safety auxiliary facilities, and in particular to a cone barrel recovery bracket and method. Background Art

[0002] Cones are important warning facilities for implementing road maintenance and traffic control. With the continuous increase in highway maintenance mileage, the volume of traffic cone retraction and deployment operations is increasing, and safety issues in the operation process are becoming increasingly prominent. At present, the retraction and deployment of traffic cones in road maintenance and control mainly rely on manual labor. Some advanced units use semi-automatic cone retraction and deployment machines, but there are still problems such as low operating efficiency, high risk, long traffic impact events, and insufficient standardization of cone deployment. These problems are particularly prominent in the maintenance process of highways. Therefore, the automation and intelligence of traffic cone retraction and deployment operations are the key guarantee for achieving efficient, economical, safe and reliable road management.

[0003] Chinese patent CN202111444696.3 discloses a fully automatic device and method for collecting and releasing cone barrels. In the patent, a recovery frame for cone barrels is disclosed. In the patent, the fixed seat of the recovery frame, the first frame and the second frame are set to be rotatably connected, that is, the entire recovery frame can be folded. When the recovery frame is used to recover the cone barrel, the cone barrel reaches the guide part after passing through the feed port, and then enters the waiting part through the through port. The cone barrel waits for the robot to grab it in the waiting part. Since the width of the through port is fixed, its use is limited for cone barrels of different specifications, and the cone barrel needs to be gathered to the guide part once, and then gathered to the waiting part for a second time. When recovering the cone barrel, the first frame and the second frame are opened at the same time, so that the roller contacts the ground, and the walking device is started to make it walk in the direction of the rear end. The cone barrels within the width range of the walking device randomly enter the feed port. However, since the first frame and the second frame are hinged, and multiple second frames are hinged on one first frame, it is difficult to open the first frame and multiple second frames at the same time. In the prior art, the first frame and the second frame are usually opened manually by 2 to 3 operators. Summary of the invention

The connecting rod 23 is inserted into the sleeve 7 on the two swing arms 2, and there is an interference fit between the connecting rod 23 and the sleeve 7, so that the connecting rod 23 is difficult to rotate in the sleeve 7.

[0043] See also Figure 1 and Figure 3In a more preferred embodiment, the frame body 21 includes a frame plate 211, a frame rod 212 and a rotating sleeve rod 213, wherein the rotating sleeve rod 213 is sleeved on the connecting rod 23, the frame rod 212 is connected to the rotating sleeve rod 313, the roller 22 is connected to the bottom of the frame rod 212, the frame plate 211 is connected to the rotating sleeve rod 213 and the frame rod 211, and the frame plate 211 is located at the top of the frame rod 212; wherein the frame plate 211 is a triangular frame plate 211, so that the to-be-grasped portion 210 formed between two adjacent frame plates 212 on the connecting rod 23 is a conical to-be-grasped portion, which is suitable for the shape of a cone barrel. When the rotating sleeve rod 213 is sleeved on the connecting rod 23, the inner diameter of the rotating sleeve rod 213 is larger than the outer diameter of the connecting rod 23, so that the rotating sleeve rod 213 can be easily rotated on the connecting rod 23.

[0044] Specifically, the frame plate 211 is connected to the frame rod 212 through a hinge, and the frame plate 211 can be connected to the rotating sleeve rod 213 by welding.

[0045] See also Figure 1 and Figure 3 In a preferred embodiment, the swing arm 1 includes a first swing portion 11 and a second swing portion 12, and the first swing portion 11 and the second swing portion 12 are arranged at an obtuse angle. The mounting assembly includes a mounting plate 42 and a connecting rod 43, wherein the connecting rod 43 is connected to the two swing arms 2, the mounting plate 42 is connected to the connecting rod 43, and the electric push rod 41 is mounted on the mounting plate 42. The connecting rod 43 is connected to the second swing portion 12 of the swing arm 1.

[0046] Since the recovery bracket is provided with multiple frames 21, the connecting rod 43 is connected to the two swing arms 1. At each corresponding frame 21 position, the connecting rod 43 is connected to a mounting plate 42, and an electric push rod 41 is installed on the mounting plate 42, so that each frame 21 can be pushed.

[0047] See also Figure 1 Specifically, since the first swing part 11 and the second swing part 12 of the swing arm 1 are arranged at an obtuse angle, when the swing arm 1 is folded onto the walking device 300, the first swing part 11 is in a vertical state relative to the ground, and the second swing part 12 will lean on the walking device 300, so that the entire folded recovery bracket can be leaned on the walking device 300.

[0048] See also Figure 3 Specifically, an opening is provided on the swing arm 2, and the connecting rod 43 is connected in the opening. For example, it can be detachably connected in the opening of the second swing part 12 of the swing arm 1 by screws.

[0049] See also Figure 1 In a preferred embodiment, the swing arm 1 is connected to the traveling device through a rotating component 8, and the rotating component 8 includes a connecting block 81, a supporting plate 82 connected to the connecting block 81, and a fixed shaft 83 connected to the supporting plate 82.

After the swing arm 1 is sleeved on the fixed shaft 83, the two ends of the fixed shaft 83 are tightened by nuts.

[0050] In the above-mentioned recovery bracket, an electric push rod with a large stroke can be used to replace the pneumatic telescopic rod 31, and a pneumatic telescopic rod with a small stroke can also be used to replace the electric push rod 41.

[0051] The present invention also provides a method for recycling a cone barrel, using the above-mentioned recycling bracket, the recycling method comprising:

[0052] S1. Connect the pneumatic telescopic rod and the electric push rod to the control unit respectively, and push the swing arm to rotate through the pneumatic telescopic rod to unfold the swing arm from the walking device. When the swing arm rotates to a certain angle, the electric push rod pushes the frame to unfold the frame from the swing arm. When the swing arm rotates to the roller on the frame and contacts the ground, the electric push rod retracts, and then the swing arm continues to rotate until the frame is placed horizontally relative to the ground, so that the recovery bracket is changed from a folded state to an unfolded state.

[0053] Specifically, when the swing arm rotates to 60° to 65°, the electric push rod pushes the frame to unfold the frame from the swing arm.

[0054] See also Figure 1 and Figure 4 When the swing arm 1 is rotated and unfolded from the walking device 300, when the swing arm 1 is rotated to Figure 4 After the state shown, the frame 21 is in a state under the premise of its own gravity. Figure 4The frame 21 is at position 200, that is, the frame 21 is not deployed from the swing arm 1 at this moment. At this time, the electric push rod 41 pushes the frame 21 to rotate from position 200 to position 201, even if the frame 21 is not vertically arranged relative to the ground, the purpose is to make the roller 22 on the frame 21 contact the ground first. When the frame 21 is pushed to be deployed to a certain angle, the swing arm 1 continues to rotate. When the roller 22 on the frame 21 away from the end of the swing arm 1 contacts the ground, the electric push rod 41 retracts and no longer supports the frame 21. The frame 21 is supported by the roller 22 that contacts the ground first. As the swing arm 1 continues to rotate and the roller 22 supports it, the roller 22 on the other side of the frame 21 will gradually drop and finally contact the ground, so that the entire frame 21 is placed horizontally relative to the ground, and the frame 21 is successfully deployed from the swing arm 1.

[0055] In order to facilitate the folding and unfolding of the entire recovery bracket, in a preferred embodiment, the two frames 21 in the middle of the recovery bracket use the same rotating sleeve rod 213, and the frame plates 211 of the two frames 21 are fixed to the same rotating sleeve rod 213. Therefore, for the two middle frames 21, one electric push rod 41 or two electric push rods 41 can be used.

[0056] S2. When the recovery bracket becomes unfolded, the part to be grasped on the bracket is horizontally arranged relative to the ground, and the cone barrels are gathered to the part to be grasped. The detection component detects whether there are cone barrels on the part to be grasped, and generates a corresponding detection signal to be transmitted to the control unit. The control unit controls the robot to grasp the cone barrels on the part to be grasped and place them into the recovery device according to the detection signal to complete the recovery of the cone barrels.

[0057] In the above-mentioned cone barrel recycling method, since the recycling bracket is provided with a plurality of frames 21, each frame 21 is provided with an electric push rod 41, all the electric push rods 41 can be uniformly controlled by a master control switch, and the master control switch is connected to a control unit, and the control unit can simultaneously push all the electric push rods 41. In addition, each electric push rod 41 is provided with an independent switch, so as to facilitate the maintenance of the electric push rod 41.

[0058] In the cone barrel recycling method described above, the electrical control of the pneumatic telescopic rod 31 is achieved through a control unit. The control unit is a common technology in production and can achieve automated control of the pneumatic telescopic rod 31.

[0059] In the cone barrel recycling method described above, corresponding control programs are used between the photoelectric detection device, the control unit and the robot to enable the robot to grab the cone barrel according to the detection signal of the detection component, and the control unit first controls the pneumatic telescopic rod 31 and then controls the electric push rod 41, which can be achieved by using the corresponding control program. Similarly, the control unit controls multiple electric push rods 41 to push simultaneously, which can also be achieved by using the corresponding control program.

[0060] In summary, the recycling bracket and method for cone barrels provided by the present invention can solve the problem in the prior art that the recycling bracket is difficult to adapt to the recycling of cone barrels of different specifications and requires secondary collection, and can also realize automatic folding and unfolding of the recycling bracket.

[0061] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
