Description

Technical Field

[0001] This invention relates to an automatic deployment and retrieval system for traffic cone pre-processing devices, a deployment and retrieval vehicle, and a deployment and retrieval method, belonging to the technical field of traffic cone deployment and retrieval equipment. Background Technology

[0002] When traffic cones are being retracted, various factors can cause them to adopt different postures, resulting in a chaotic arrangement or even a lying position. Therefore, pre-treatment devices are widely used to adjust the posture of traffic cones. However, these devices are often installed and adjusted manually before operation, which is labor-intensive and poses significant safety hazards during the manual installation process before each operation.

[0003] The automatic retraction system for the pretreatment unit is mounted on the side of the vehicle and must be completely retracted under the chassis during driving, not exceeding the vehicle's width. Due to the location of the fuel tank and chassis components under the chassis, the lateral space available for the pretreatment unit's retraction is limited, and sufficient ground clearance is required during driving. When the treatment unit is in operation, the height of the first guide rod must be sufficient to push the traffic cone. At this point, the bottom support wheels of the second and third guide rods touch the ground, allowing the guide rods to guide the traffic cone. The guiding operation requires a stable angle between the guide rod and the first guide rod, without any swaying. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an automatic deployment and retrieval system, deployment and retrieval vehicle, and deployment and retrieval method for traffic cone pre-processing devices, which features small lateral deployment and retrieval space, high ground clearance, and no swaying during operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic deployment and retraction system for a traffic cone pre-treatment device includes a guide rail base, a guide rail frame, a pre-treatment device, an electric push rod I, and an electric push rod II.

[0007] The guide rail base is connected to the frame, and the guide rail frame is installed on the guide rail base. One end of the electric push rod I is connected to the guide rail base, and the other end is connected to the guide rail frame. The electric push rod I is used to push the guide rail frame to move up and down along the guide rail base.

[0008] The pretreatment device is hinged to the guide rail frame. One end of the electric push rod II is connected to the guide rail frame and the other end is connected to the pretreatment device. The electric push rod II is used to push the pretreatment device to swing along the guide rail frame.

[0010] The end of the first guide rod is hinged to the guide rail frame, and the two sides of the first guide rod are slidably connected to the second and third guide rods. The bottom of the second and third guide rods are equipped with support wheels.

[0011] Upper limit plates are installed on the two columns of the first guide rod, and electromagnetic locks are installed on the upper limit plates. The lower ends of the second and third guide rods are respectively provided with lower limit plates, and the lower limit plates are provided with limit holes. When the first guide rod moves down to the lowest position, the electromagnetic lock is energized, and the lock tongue extends and inserts into the limit hole of the lower limit plate.

[0012] Furthermore, the aforementioned guide rail base is equipped with a slide rail, and the guide rail frame includes a fixed hinge seat I, a hinge seat II, a hydraulic cylinder hinge seat, a slide rail groove, and a connecting frame.

[0013] The slide rail groove is installed on the slide rail, and a connecting frame is fixed between the slide rail grooves. The connecting frame is equipped with a hydraulic cylinder hinge seat, which is used to fix and connect the electric push rod I.

[0016] Furthermore, the aforementioned pretreatment device also includes a rotary support I and several rotary supports II. Hinges I are respectively installed at both ends of the first guide rod, and a first limiting block is installed on the hinge I. Hinges II are installed on the second guide rod and the third guide rod, and a second limiting block is installed on the hinge II.

[0017] Rotary support II has a concave hinge point and a convex hinge point at both ends. Rotary support II is connected end to end through the concave hinge point and the convex hinge point. The concave hinge point of the first end of rotary support II is hinged to one end of rotary support I. The other end of rotary support I is hinged to hinge seat I. Rotary support I is located below the first limiting block. The convex hinge point of the last end of rotary support II is hinged to hinge seat II.

[0038] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations thereof. In the absence of conflict, the embodiments and technical features in the embodiments can be combined with each other.

[0039] Example 1

[0040] This embodiment discloses a fully automatic deployment and retraction system for a traffic cone pre-processing device, such as... Figure 1 As shown, the device includes a guide rail base 1, a guide rail frame 2, a pre-treatment device 3, an electric push rod I 4, and an electric push rod II 5. The guide rail base 1 serves as the base frame of the fully automatic traffic cone pre-treatment device's deployment and retraction system and is connected to the vehicle frame. The guide rail frame 2 is mounted on the slide rail 1-1 of the guide rail base 1 and slides up and down via the extension and retraction of the electric push rod I 4. The hinge seat II 2-2 of the guide rail frame 2 is hinged to the pre-treatment device, and the hinge seat I 2-1 is hinged to the electric push rod II 5. The other end of the electric push rod II 5 is hinged to the end of the first guide rod 3-1 of the pre-treatment device 3. The extension and retraction of the electric push rod II 5 causes the pre-treatment device 3 to swing.

[0041] Figure 2 As shown, hinge seat I 2-1, hinge seat II 2-2, hydraulic cylinder hinge seat 2-3, and slide rail groove 2-4 are fixed on the guide rail frame 2. The slide rail groove 2-4 is installed on the slide rail 1-1. A connecting frame 2-5 is fixed between the slide rail grooves 2-4. The hydraulic cylinder hinge seat 2-3 is installed on the connecting frame 2-5. Hinge seat I 2-1 is located on one side of the guide rail frame and is used to install the hinge point of the electric push rod II 5 cylinder seat. Hinge seat II 2-2 is located on the other side of the guide rail frame. The upper and lower plates of hinge seat II 2-2 are provided with two long ears along the hinge point, which can support the first guide rod 3-1 in both traveling and working states, preventing the overhanging part of the first guide rod 3-1 from sagging and causing tilting. The hydraulic cylinder hinge seat 2-3 is used to connect the movable end of the electric push rod I 4.

[0042] Figure 3As shown, the pretreatment device 3 includes a first guide rod 3-1, a second guide rod 3-2, a third guide rod 3-3, a rotary support I 3-4, a rotary support II 3-5, a support wheel 3-6, and an electromagnetic lock 3-7. The second guide rod 3-2 and the third guide rod 3-3 are slidably connected to both sides of the first guide rod 3-1. Support wheels 3-6 are located at the bottom of the second guide rod 3-2 and the third guide rod 3-3. Rotary supports I 3-4 and three rotary supports II 3-5 are sequentially installed between the first guide rod 3-1 and the second guide rod 3-2, and between the first guide rod 3-1 and the third guide rod 3-3. Figure 6 Upper limit plates 3-1-2 are installed on the two uprights of the first guide rod 3-1. Electromagnetic locks 3-7 are installed on the upper limit plates 3-1-2. Lower limit plates 3-2-2 are installed on the second guide rod 3-2 and the third guide rod 3-3. When the guide rail frame 2 moves to its lowest position, the electromagnetic lock 3-7 is energized, and the locking tongue extends from the upper limit plate 3-1-2 and inserts into the lower limit plate 3-2-2. Figure 6 As shown, at this time, the second guide rod 3-2 and the third guide rod 3-3 are locked relative to the first guide rod 3-1.

[0043] As shown in Figure 4, two hinge seats I3-1-1 are installed on the first guide rod 3-1, and a first limiting block is installed on the hinge seat I3-1-1; one hinge seat II3-2-1 is installed on the second guide rod 3-2 and the third guide rod 3-3, and a second limiting block is installed on the hinge seat II3-2-1. For the first guide rod 3-1 and the second guide rod 3-2, the rotary support I3-4 is hinged to the hinge seat I3-1-1 on the first guide rod 3-1 below the first limiting block; another hinge point of the rotary support I3-4 is hinged to the concave hinge point of the first rotary support II3-5, and the convex hinge point of the first rotary support II3-5 is hinged to the concave hinge point of the second rotary support II3-5; similarly, the convex hinge point of the second rotary support II3-5 is hinged to the concave hinge point of the third rotary support II3-5, and the convex hinge point of the third rotary support II3-5 is hinged to the hinge seat II3-2-1 above the second limiting block of the second guide rod 3-2. Rotary support I 3-4, which is hinged to the hinge point of the first guide rod 3-1, and rotary support II 3-5, which is hinged to the hinge point of the second guide rod, have a swing angle of less than 90° due to the limiting block. The limiting end face of the limiting block at the concave hinge point of rotary support II 3-5 has a limiting rotation angle of less than 180° with the limiting surface of the upper rotary support. The limiting block is used to prevent the rotation angle from exceeding the dead point and to prevent the rotary support from failing to reset.

[0044] Furthermore, the rotational support connection between the first guide rod 3-1 and the third guide rod 3-3 is the same as described above.

[0045] Example 2

[0046] This invention also provides an automatic traffic cone pre-treatment device vehicle, wherein the vehicle body is connected to the traffic cone pre-treatment device.

[0047] Example 3

[0048] This invention also provides an automatic deployment and retraction method for a traffic cone pre-treatment device, the method comprising the following steps:

[0049] The guide rail seat 1 is fixed to the side of the vehicle frame as a base frame. The electric push rod I4 is extended, the guide rail 2 is moved down to the lowest end, the support wheels 3-6 touch the ground, the electric push rod II5 is retracted, and the pre-processing device 3 swings 90° along the hinge point of the guide rail seat 2 to the working position.

[0050] When the electromagnetic lock 3-7 is de-energized, the bolt retracts, and the locking of the second guide rod 3-2 and the third guide rod 3-3 is released, allowing them to slide freely. Under the constraint of the rotary support I 3-4 and rotary support II 3-5 mechanisms, the second guide rod 3-2 and the third guide rod 3-3 only slide up and down without oscillation.

[0051] Retract the electric push rod I4, causing the guide rail seat 2 to move the first guide rod 3-1 to its highest position, as shown. Figure 4a As shown, traffic cones can be pre-processed.

[0052] After construction is completed, extend the electric push rod I4. When the guide rail 2 moves to its lowest position (e.g.) Figure 4b As shown), when the electromagnetic lock 3-7 is energized, the locking tongue extends from the upper limit plate 3-1-2 and inserts into the lower limit plate 3-2-2. At this time, the second guide rod 3-2 and the third guide rod 3-3 are locked relative to the first guide rod 3-1.

[0053] Extend the electric push rod II5, and the pre-processing device 3 swings along the hinge point of the guide rail seat 2 from the low position to the bottom of the frame. Retract the electric push rod I4 to the upper limit position. At this time, the device is in the driving state.

[0054] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
