Abstract
Description
Technical Field
[0001] This invention relates to the field of highway equipment, and more particularly to a guiding mechanism. Background Technology
[0002] Intelligent traffic robots use existing highway guardrails as guide rails to perform functions such as patrolling and monitoring the road surface, issuing violation warnings, and detecting foreign objects on the road. However, the current connection between the robot and the guardrail is a hook-type connection, which is unreliable and prone to derailment, causing traffic accidents such as derailment of intelligent traffic robots and affecting their normal operation. Summary of the Invention
[0003] This solution addresses the problems and needs raised above by proposing a guiding mechanism that achieves the aforementioned technical objectives and brings about several other technical benefits due to the adoption of the following technical features.
[0004] This invention proposes a guiding mechanism for use on highway guardrails, wherein the guardrail includes a corrugated plate, and the guiding mechanism comprises:
[0005] The walking unit includes multiple walking wheels and permanent magnets, wherein the walking wheels are adapted to walk on the upper surface of the corrugated plate of the guardrail, and the permanent magnets are adapted to attract the guide mechanism to the corrugated plate;
[0006] A snap-fit portion is connected to both sides of the walking portion, and the snap-fit portion located on at least one side of the walking portion is connected to the walking portion by a first elastic member, so that the snap-fit portion can be adaptively attached to the wave plate.
[0007] In this technical solution, the locking part can lock the guide mechanism onto the upper edge of the corrugated plate, and the traveling wheels on the traveling part roll on the upper surface of the corrugated plate to realize the reciprocating movement of the guide mechanism along the extension direction of the guardrail. During this process, the permanent magnet attracts the guide mechanism to the corrugated plate, preventing the guide mechanism from derailing on the corrugated plate. By setting a first elastic element between the locking part and the traveling part, the self-adaptability between the guide mechanism and the corrugated plate can be realized, avoiding the deformation of the corrugated plate that could cause the guide mechanism to jam. This guide mechanism has good stability, stable movement, convenient turning, strong climbing ability, and can adaptively cooperate with the corrugated plate to prevent derailment.
[0008] In addition, the guiding mechanism according to the present invention may also have the following technical features:
[0009] In one example of the present invention, the snap-fit portion includes:
[0010] The first snap-fit arm has one end hinged to one side of the walking part, and the other end configured to snap onto the upper edge of the corrugated plate.
[0011] The second snap-fit arm has one end fixedly connected to the other side of the walking part, and the other end is configured to snap onto the crest of the wave plate.
[0012] The first elastic element is connected between the first snap-fit arm and the traveling part, and the first snap-fit arm has a directional force that moves toward the side of the corrugated plate.
[0013] In one example of the present invention, a first guide wheel is disposed on the first snap-fit arm, the first guide wheel being adapted to snap onto the upper edge of the waveform plate, and a second guide wheel is disposed on the second snap-fit arm, the second guide wheel being adapted to snap onto the crest of the waveform plate.
[0014] In one example of the present invention, the snap-fit portion further includes:
[0015] An auxiliary block is disposed at least on one side of the first guide wheel along the extension direction of the waveform plate and is adapted to the upper edge of the waveform plate.
[0016] In one example of the present invention, the surface of the auxiliary block opposite to the upper edge of the waveform plate is an arc-shaped surface, and the arc-shaped surface has a U-shaped guide surface that cooperates with the upper edge of the waveform plate. The distance between the U-shaped guide surface and the upper edge of the waveform plate gradually increases from the side closer to the first guide wheel to the side away from the first guide wheel.
[0017] In one example of the present invention, the curvature of the U-shaped guide surface in the radial direction of the arc surface gradually decreases from the side with a larger distance from the upper edge of the waveform plate to the side with a smaller distance.
[0018] In one example of the present invention, the snap-fit portion further includes:
[0019] A connecting plate is pivotally connected to the first snap-fit arm, and an auxiliary block is connected to the connecting plate. The connecting plate and the first snap-fit arm are connected by a second elastic element, so that the auxiliary block adaptively contacts the upper edge of the waveform plate.
[0020] In one example of the invention, it also includes:
[0021] Limiting mechanism, which includes:
[0022] The device includes a limiting post and a limiting plate, wherein a limiting post is disposed on one of the traveling part and the locking part, and a limiting plate is disposed on the other. The limiting post or the limiting plate can move synchronously with the locking part, and the limiting plate or the limiting post is used to limit the range of movement of the limiting post or the limiting plate.
[0023] In one example of the present invention, a second pivot at the hinge point between the walking part and the snap-fit part is taken as the center, and a preset value is used as the radius. Multiple mounting holes are provided on the walking part or the snap-fit part, and the limiting post is detachably installed in any one of the mounting holes.
[0024] In one example of the present invention, the permanent magnet is connected to the walking part by fasteners, and the distance between the permanent magnet and the upper end face of the corrugated plate is adjustable by fasteners.

[0072] This invention proposes a guiding mechanism 100, such as... Figures 1 to 5 As shown, this is applied to a highway guardrail, the guardrail including a corrugated plate 200, and the guide mechanism 100 including:
[0073] The walking part 110 includes a plurality of walking wheels 113 and permanent magnets 114, wherein the walking wheels 113 are adapted to walk on the upper end surface 210 of the corrugated plate 200 of the guardrail, and the permanent magnets 114 are adapted to attract the guide mechanism 100 onto the corrugated plate 200.
[0074] The snap-fit portion 120 is connected to both sides of the walking portion 110, and the snap-fit portion 120 located on at least one side of the walking portion 110 is connected to the walking portion 110 through a first elastic member 130, so that the snap-fit portion 120 can be adaptively attached to the wave plate 200.
[0075] In other words, the locking part 120 can lock the guide mechanism 100 onto the upper edge 220 of the corrugated plate 200, and the traveling wheel 113 on the traveling part 110 rolls on the upper surface 210 of the corrugated plate 200 to achieve reciprocating movement of the guide mechanism 100 along the extension direction of the guardrail. During this process, the permanent magnet 114 attracts the guide mechanism 100 onto the corrugated plate 200 to prevent the guide mechanism 100 from derailing on the corrugated plate 200. By setting the first elastic element 130 between the locking part 120 and the traveling part 110, the self-adaptability between the guide mechanism 100 and the corrugated plate 200 can be achieved, avoiding the deformation of the corrugated plate 200 and causing the guide mechanism 100 to jam. The guide mechanism 100 has good stability, stable movement, convenient turning, strong climbing ability, and can adapt to the corrugated plate 200 to prevent derailment. It is worth noting that the guide mechanism 200 generally encounters the following working conditions: the corrugated plate 200 is deformed or the connection between two corrugated plates 200. In particular, at the connection between two corrugated plates 200, the straightness of the two corrugated plates 200 is poor during installation, and the two corrugated plates 200 will be offset.
[0076] In one example of the present invention, the snap-fit portion 120 includes:
[0077] The first snap-fit arm 121 has one end hinged to one side of the walking part 110, and the other end is configured to snap onto the upper edge 220 of the corrugated plate 200.
[0078] The second snap-fit arm 122 has one end fixedly connected to the other side of the walking part 110, and the other end is configured to snap onto the crest 230 of the waveform plate 200.
[0079] The first elastic element 130 is connected between the first snap-fit arm 121 and the walking part 110, and the end of the first snap-fit arm 121 connected to the first guide wheel 1213 has a tendency force to move toward the side of the wave plate 200.
[0080] In other words, under the action of the first elastic element 130, the first locking arm 121 is flexibly connected to the upper edge 220 of the corrugated plate 200. When the corrugated plate 200 deforms, the first locking arm 121 will move toward or away from the corrugated plate 200, causing the first locking arm 121 to pivot relative to the traveling part 110. When the traveling wheel 113 passes through the deformation area, the first locking arm 121 returns to its initial position under the action of the elastic force of the first elastic element 130, that is, it always maintains cooperation with the upper edge 220 of the corrugated plate 200 to prevent derailment.
[0081] Of course, the present invention is not limited thereto. The second snap-fit arm 122 and the walking part 110 can also be connected by a hinged connection. A first elastic element 130 is arranged between the second snap-fit arm 122 and the walking part 110. The first elastic element 130 enables the second snap-fit arm 122 to adaptively connect with the wave crest 230 of the waveform plate 200.
[0082] It is worth noting that the first latching arm 121 and the second latching arm 122 are not limited to latching onto the upper edge 220 and the crest 230. For example, the first latching arm 121 and the second latching arm 122 can be latched onto opposite sides of the wave plate 220, as long as the guide mechanism 100 can be latched.
[0083] In one example of the present invention, a first guide wheel 1213 is disposed on the first snap-fit arm 121, and the first guide wheel 1213 is adapted to snap onto the upper edge 220 of the waveform plate 200;
[0084] Under the action of the first elastic member 130, the first guide wheel 1213 is flexibly connected to the upper edge 220 of the corrugated plate 200. When encountering a deformed part of the corrugated plate 200 or a connection point of two corrugated plates 200, the first guide wheel 1213 will move towards or away from the corrugated plate 200. This causes the first guide wheel 121 to move towards or away from the corrugated plate 200, ultimately causing the first locking arm 121 to pivot relative to the traveling part 110. When the traveling wheel 113 passes through the deformed area, the first locking arm 121, under the action of the elastic force of the first elastic member 130, causes the first guide wheel 1213 to return to its initial position, that is, to always maintain cooperation with the upper edge 220 of the corrugated plate 200. This allows the first guide wheel 1213 to adaptively cooperate with the corrugated plate 200, preventing derailment.
[0085] In one example of the present invention, a second guide wheel 1223 is disposed on the second snap-fit arm 122, and the second guide wheel 1223 is adapted to snap onto the crest 230 of the waveform plate 200;
[0086] To further improve the stability of the guide mechanism 100, a second guide wheel 1223 is provided on the second locking arm 122, which together with the first locking arm 121 can stably clamp the guide mechanism 100 onto the corrugated plate 200. The second guide wheel 1223 is provided on the other end of the walking part 110, which can play a guiding role and at the same time reduce the friction between the guide mechanism 100 and the corrugated plate 200.
[0087] Preferably, a concave groove is provided along the circumferential direction of the second guide wheel 1223, and the concave groove is adapted to the crest 230 of the corrugated plate 200, thereby further improving the stability and reliability of the cooperation between the second guide wheel 1223 and the corrugated plate 200.
[0088] In one example of the present invention, the snap-fit portion 120 further includes:
[0089] An auxiliary block 123 is disposed on at least one side of the first guide wheel 1213 along the extending direction of the corrugated plate 200 and adapted to the upper edge 220 of the corrugated plate 200, for increasing the contact area between the first guide wheel 1213 and the upper edge 220 of the corrugated plate 200.
[0090] Because the stability between the first guide wheel 1213 and the upper edge 220 of the corrugated plate 200 is insufficient during movement, the corrugated plate 200 is prone to swaying if it deforms or at the connection between the two corrugated plates 200, which may lead to derailment. In order to further improve the reliability and stability of the connection between the first guide wheel 1213 and the upper edge 220 of the corrugated plate 200, an auxiliary block 123 is provided on at least one side of the first guide wheel 1213 to increase the contact area between the first guide wheel 1213 and the upper edge 220 of the corrugated plate 200, thereby improving the reliability of the connection between the two.
[0091] Preferably, the auxiliary block 123 includes two blocks, and the two auxiliary blocks 123 are symmetrically arranged on both sides of the first guide wheel 1213. In this way, when the guide mechanism 100 reciprocates along the extension direction of the corrugated plate 200, it can increase the contact area with the upper edge 220 of the corrugated plate 200, thereby further improving the stability of the first guide wheel 1213.
[0092] In one example of the present invention, such as Figure 6As shown, the surface of the auxiliary block 123 opposite to the upper edge 220 of the waveform plate 200 is an arc-shaped surface 1231, and the arc-shaped surface 1231 has a U-shaped guide surface 1232 that cooperates with the upper edge 220 of the waveform plate 200. The distance between the U-shaped guide surface 1232 and the upper edge 220 of the waveform plate 200 gradually increases from the side closer to the first guide wheel 1213 to the side away from the first guide wheel 1213.
[0093] In other words, by setting the U-shaped guide surface 1232, the auxiliary block 123 can be engaged with the upper edge 220 of the corrugated plate 200, improving the reliability of the connection between the two. Designing the U-shaped guide surface 1232 as an arc surface 1231 structure facilitates the cooperation between the auxiliary block 123 and the deformation point of the corrugated plate 200 or the connection point of the two corrugated plates 200, which can improve the ability of the auxiliary block 123 to pass through the deformation point of the corrugated plate 200 or the connection point of the two corrugated plates 200, and further improve the stability of the first guide wheel 1213.
[0094] In one example of the present invention, the curvature of the U-shaped guide surface 1232 in the radial direction of the arc surface 1231 gradually decreases from the side with a larger distance from the upper edge 220 of the waveform plate 200 to the side with a smaller distance.
[0095] In other words, the opening of the U-shaped guide surface 1232 on the side of the arc surface 1231 that is farther from the upper edge 220 of the waveform plate 200 is larger, while the opening of the U-shaped guide surface 1232 on the side of the arc surface 1231 that is closer to the upper edge 220 of the waveform plate 200 is smaller. This allows the guide mechanism 100 to better transition between the two points when the U-shaped guide surface 1232 encounters the deformation point of the waveform plate 200 or the connection point of two waveform plates 200, thereby improving the adaptability and stability of the guide mechanism 100.
[0096] In one example of the present invention, the snap-fit portion 120 further includes:
[0097] A connecting plate 124 is pivotally connected to the first snap-fit arm 121, and an auxiliary block 123 is connected to the connecting plate 124. For example, the auxiliary block 123 is fixedly connected to the connecting plate 124 by fasteners. The connecting plate 124 and the first snap-fit arm 121 are connected by a second elastic member 125, so that the auxiliary block 123 adaptively contacts the upper edge 220 of the waveform plate 200.
[0098] Specifically, the connecting plate 124 is arranged along the extension direction of the waveform plate 200. For example, the connecting plate 124 can be pivotally connected to the first rotating shaft 1215 of the first snap-fit arm 121. The second elastic member 125 allows the connecting plate 124 to swing adaptively when it is subjected to the impact of the deformation of the waveform plate 200 or the connection of the two waveform plates 200, so that the auxiliary block 123 adaptively cooperates with the upper edge 220 of the waveform plate 200, further improving the adaptability of the auxiliary block 123.
[0099] It is worth noting that when there are two auxiliary blocks 123, two second elastic elements 125 are symmetrically arranged on both sides of the connecting plate 124, so that the forces on both sides of the connecting plate 124 are balanced, thereby improving the adaptability of the connecting plate 124.
[0100] In one example of the present invention, the second elastic element 125 is either a tension spring or a torsion spring;
[0101] When the second elastic element 125 is a tension spring, the following example illustrates the use of two auxiliary blocks 123 symmetrically arranged on both sides of the connecting plate 124. One end of each second elastic element 125 is connected to the connecting plate 124, and the other end is connected to the first snap-fit arm 121. When the guide mechanism 100 encounters a deformed part of the corrugated plate 200 or a joint of two corrugated plates 200, the following example illustrates the outward protrusion deformation of the corrugated plate 200. The auxiliary block 123 on the side that first contacts the protrusion deformation moves away from the corrugated plate 200 due to the force of the protrusion deformation, while the auxiliary block 123 on the other side moves closer to the corrugated plate 200. At the same time, the second elastic element 125 on that side undergoes a stretching motion and generates an elastic force. When the auxiliary block 123 on the side that first contacts the protrusion deformation... When the auxiliary block 123 passes over the protruding deformation, the side that first contacts the protruding deformation is stretched by the elastic force of the side that subsequently contacts the protruding deformation, thus having a tendency to return to its initial position and returning to its initial position. When the auxiliary block 123 that subsequently contacts the protruding deformation, the auxiliary block 123 that subsequently contacts the protruding deformation moves away from the corrugated plate 200 under the force of the protruding deformation, while the auxiliary block 123 that first contacts the protruding deformation moves towards the corrugated plate 200, and at the same time, the second elastic element 125 on that side performs a stretching movement and generates an elastic force. When the auxiliary block 123 that subsequently contacts the protruding deformation passes over the protruding deformation, the side that subsequently contacts the protruding deformation is stretched by the elastic force of the side that first contacts the protruding deformation, thus having a tendency to return to its initial position and returning to its initial position. It is understood that in other cases of deformation of the corrugated plate 200, the movement of the connecting plate 124 can be predicted according to the actual situation, and will not be elaborated here.
[0102] When the second elastic element 125 is a torsion spring, such as Figure 7 , Figure 8As shown, the torsion spring includes two springs, both of which are sleeved on the first rotating shaft 1215 and respectively disposed on both sides of the connecting plate 124. One end pin 1251 of each torsion spring is fixedly connected to the first rotating shaft 1215, and the other end pin 1251 is connected to the connecting plate 124; wherein, the two torsion springs are subjected to opposite forces.
[0103] In other words, during the rotation of the connecting plate 124 in one direction, only one torsion spring is active, while the other is inactive. This gives the connecting plate 124 a tendency to return to its initial position after rotation in one direction. Specifically, a groove 1241 is provided on the connecting plate 124, with each groove 1241 extending in the opposite direction to the force of the torsion spring. This ensures that when the connecting plate 124 rotates in one direction, one torsion spring moves in the direction of the force and generates a tendency to return to its initial position, while the other torsion spring moves in the opposite direction. Because of the groove 1241 on the connecting plate 124, the pin 1251 of the torsion spring slides along the groove 1241, preventing the pin 1251 connected to the connecting plate 124 from being pushed by the connecting plate 124 and moving in the opposite direction, thus affecting its normal use. The above structure enables the swinging use of the connecting plate 124. In other words, the example of the corrugated plate 200 protruding outward is still used for explanation. When the auxiliary block 123 that first contacts the protruding deformation moves away from the corrugated plate 200 due to the force of the protruding deformation (e.g., rotating in the Z direction), while the other auxiliary block 123 moves closer to the corrugated plate 200, one of the torsion springs receives a steering force and moves, generating an elastic force. When the auxiliary block 123 that first contacts the protruding deformation passes the protruding deformation, the side that first contacts the protruding deformation returns to its initial position under the action of the torsion spring's elastic force. When the auxiliary block 123 that contacts the protruding deformation later, the auxiliary block 123 that contacts the protruding deformation moves away from the corrugated plate 200 due to the force of the protruding deformation (e.g., in the N direction, opposite to the Z direction), while the other auxiliary block 123 that first contacts the protruding deformation moves closer to the corrugated plate 200, and at the same time, another torsion spring receives a steering force and moves, generating an elastic force. When the auxiliary block 123 that contacts the protruding deformation later passes the protruding deformation, the side that contacts the protruding deformation later returns to its initial position under the action of the torsion spring's elastic force. It should be noted that, for ease of use... Figure 7 For illustrative purposes, only pin 125 located within the slide 1241 is shown in the diagram.
[0104] In one example of the present invention, the first card arm 121 includes:
[0105] A first arm 1211 and a second arm 1212 are connected to each other, and the first arm 1211 and the second arm 1212 form an angle A between them;
[0106] The first arm 1211 is hinged to the walking part 110, and the first guide wheel 1213 is disposed on the second arm 1212;
[0107] Since the upper end surface 210 of the corrugated plate 200 is an inclined surface, the guide mechanism 100 travels on this inclined surface, and the function of the first snap-fit arm 121 is to snap-fit with the upper edge 220, the design structure of the first snap-fit arm 121 needs to form a bent state so that the guide mechanism 100 can be snapped onto the upper edge 220. The first arm 1211 and the second arm 1212, which are connected to each other, can facilitate the snap-fit function of the first snap-fit arm 121, and at the same time facilitate the cooperation and connection between the first guide wheel 1213 and the upper edge 220.
[0108] In one example of the present invention, the second card arm 122 includes:
[0109] The third arm 1221 and the fourth arm 1222 are connected to each other, and the third arm 1221 and the fourth arm 1222 form an angle B between them;
[0110] The third arm 1221 is fixedly connected to the walking part 110, and the second guide wheel 1223 is disposed on the fourth arm 1222;
[0111] Since the upper end face 210 of the corrugated plate 200 is an inclined surface, the guide mechanism 100 travels on this inclined surface, and the function of the second snap-fit arm 122 is to snap-fit with the wave crest 230, the design structure of the second snap-fit arm 122 needs to form a bent state so that the guide mechanism 100 can be snapped onto the wave crest 230. The second snap-fit arm 122 with the above structure can facilitate the connection between it and the wave crest 230.
[0112] In one example of the invention, it also includes:
[0113] Limiting mechanism, which includes:
[0114] The limiting post 1112 and the limiting plate 1214 are provided, wherein the limiting post 1112 is provided on one of the traveling part 110 and the locking part 120, and the limiting plate 1214 is provided on the other. The limiting post 1112 or the limiting plate 1214 can move synchronously with the locking part 120. The limiting plate 1214 or the limiting post 1112 is used to limit the movement range of the limiting post 1112 or the limiting plate 1214.
[0115] To achieve adaptive snap-fit connection, the first snap-fit arm 121 is hinged to the walking part 110, thus the first snap-fit arm 121 has a large range of motion. The range of motion of the first snap-fit arm 121 is flexibly limited by the first elastic member 130. However, since the first elastic member 130 itself has an elastic range, when subjected to a large impact force, the deformation of the first elastic member 130 will increase instantaneously, thereby increasing the rotation angle of the first snap-fit arm 121 beyond its preset range value and causing it to detach from the upper edge 220 of the corrugated plate 200. To prevent the above situation from occurring, a limiting mechanism is provided on the guide mechanism 100 to limit the range of motion of the first snap-fit arm 121 and prevent the first guide wheel 1213 from rotating too much and detaching from the corrugated plate 200.
[0116] For example, a limiting plate 1214 is formed on the first latching arm 121, and a limiting post 1112 is provided on the bracket 111 of the traveling part 110 and within the rotation range of the limiting plate 1214, thereby limiting the maximum rotation angle of the first latching arm 121. It should be noted that when the first latching arm 121 is at its maximum rotation angle, the guide mechanism 100 will not disengage from the corrugated plate 200. Of course, a limiting plate 1214 can also be provided on the traveling part 110, and a limiting post 1112 can be provided on the first latching arm 121. However, in this case, the limiting post 1112 rotates with the first latching arm 121, while the limiting plate 1214 remains stationary relative to the first latching arm 121. The limiting principle is similar to that described above, and will not be repeated here.
[0117] In one example of the present invention, a plurality of mounting holes 1113 are provided on the walking part 110 or the locking part 120 with the second rotating shaft 1111 at the hinge point between the walking part 110 and the locking part 120 as the center and a preset value as the radius. The limiting post 1112 is detachably installed in any one of the mounting holes 1113.
[0118] In other words, the limiting post 1112 can be connected to any of the mounting holes 1113 to adjust the range of rotation angle of the first snap-fit arm 121 defined by the limiting post 1112, thereby improving the ability of the guide mechanism 100 to adapt to different types of corrugated plates 200 and making adjustment convenient.
[0119] For example, the limiting post 1112 and the mounting hole 1113 can be connected by a threaded connection. That is, the limiting post 1112 is provided with an external thread, and each mounting hole 1113 is provided with an internal thread that mates with the external thread, thereby achieving a detachable connection between the limiting post 1112 and the mounting hole 1113. Alternatively, the limiting post 1112 can be provided with an external thread, passing through the mounting hole 1113, and nuts that mate with the external thread of the limiting post 1112 can be provided on both sides of the mounting hole 1113, thereby fixing the limiting post 1112 within the mounting hole 1113. The limiting post 1112 and the mounting hole 1113 can also be connected by other methods, as long as they facilitate disassembly.
[0120] In one example of the present invention, the walking unit 110 includes:
[0121] The bracket 111, one end of which is hinged to the first snap-fit arm 121;
[0122] The frame 112 is fixedly connected to the bracket 111, and a plurality of wheels 113 are pivotally connected to the frame 112;
[0123] The permanent magnet 114 is fixedly connected to the frame 112 and is disposed opposite to the upper end surface 210 of the corrugated plate 200.
[0124] For example, in this invention, four wheels 113 are adapted on the frame 112, and a permanent magnet 114 is fixedly connected to the frame 112 and located between the four wheels 113.
[0125] By designing the frame 112 and the bracket 111 to be installed separately, it is convenient to load and transport the running gear 110, and it is also convenient to connect the running gear 110 with the first connecting arm 121.
[0126] In one example of the present invention, the first elastic element 130 is one of four types: a tension spring, a compression spring, a sheet spring, and a rubber element.
[0127] This example uses tension springs and compression springs as illustrations. The connection between the spring sheet and the rubber is similar and will not be described in detail here.
[0128] When the first elastic element 130 is a tension spring, one end of the tension spring is connected to the walking part 110, and the other end is connected to the second arm 1212 of the first latching arm 121, so that the first latching arm 121 always has a tendency to move toward the walking part 110.
[0129] When the first elastic element 130 is a compression spring, such as Figure 9As shown, the bracket 111 extends towards one side of the first latching arm 121 to form an extension section 1216. The compression spring is installed between the extension section 1216 and the first arm portion 1211 of the first latching arm 121. This causes the compression spring to be compressed when the first guide wheel 1213 of the first latching arm 121 rotates towards the end away from the walking part 110, generating an elastic force that causes the first latching arm 121 to move towards the walking part 110. It is worth noting that in this embodiment, when the compression spring is installed on the normal wave plate 200, it is also in a compressed state, thereby ensuring the continuous effectiveness of the compression spring.
[0130] In one example of the present invention, the magnetic surface of the permanent magnet 114 opposite to the upper end surface 210 of the waveform plate 200 is parallel to the upper end surface 210 of the waveform plate 200, thereby enabling the permanent magnet 114 to exert its effective magnetic force to the maximum extent and improving the effectiveness of the permanent magnet 114.
[0131] In one example of the present invention, the permanent magnet 114 is a neodymium iron boron permanent magnet;
[0132] Specifically, a 100*80*5mm permanent magnet NdFeB is placed on a 300*100*4mm low carbon steel (Q235) material (guardrail).
[0133] When the suspension gap is set to 4mm, the calculated gravitational force on the guardrail is 113N, which is greater than the expected 10kgf (100N).
[0134] The specific parameters of the required permanent magnet can be obtained from the calculation: the volume of the permanent magnet is 10*6*0.5=30; the density of the permanent magnet is 7.5 grams per cubic centimeter; the mass of the permanent magnet is 225 grams.
[0135] In one example of the present invention, the permanent magnet 114 is connected to the walking part 110 by fasteners, and the distance between the permanent magnet 114 and the upper end face 210 of the waveform plate 200 is adjustable by fasteners.
[0136] Specifically, a plurality of first positioning holes are provided on the frame 112, and a plurality of second positioning holes are provided on the permanent magnet 114. The first positioning holes and the second positioning holes correspond one-to-one, and fasteners are sequentially passed through the first positioning holes and the second positioning holes. Preferably, the fasteners are bolts. By adjusting the fit length between the bolt and the permanent magnet 114, the distance between the permanent magnet 114 and the upper end face 210 is adjusted, thereby adjusting the attraction force between the permanent magnet 114 and the upper end face 210.
[0137] In one example of the present invention, the guide mechanism 100 further includes:
[0138] A drive device is connected to the walking wheel 113 of the walking unit 110, and the drive device is configured to drive the walking wheel 113 to rotate.
[0139] For example, the driving device can be a drive motor, which is connected to the walking wheel 113 through a reducer, thereby driving the walking wheel 113 to rotate, and then realizing the reciprocating motion of the guide mechanism 100 along the extension direction of the corrugated plate 200.
[0140] In one example of the invention, it also includes:
[0141] A remote control device, which is communicatively connected to the drive device, is configured to remotely control the movement of the drive device; the remote control device can easily manipulate the drive device to perform actions such as forward, reverse, and stop movement; the remote control device and the drive device can be connected wirelessly or via a wired cable, which is not limited here.
[0142] The exemplary embodiments of the guide mechanism 100 proposed in this invention have been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this invention, and various combinations can be made to the various technical features and structures proposed in this invention without exceeding the protection scope of this invention, which is determined by the appended claims.
