Description

Technical Field

[0001] The present application relates to the technical field of road marking construction equipment, and in particular to reactive road marking automatic unmanned construction equipment. Background Art

[0002] Road markings are marks applied to the road surface to guide vehicles and pedestrians. Reactive road markings are road markings with fluorescent or reflective materials that allow pedestrians to react quickly under lighting conditions. In the actual construction of reactive road markings, construction workers often use automatic unmanned construction equipment to apply road markings on the road.

[0003] Most of the existing automatic unmanned equipment for road marking construction includes a construction vehicle with a traction mechanism, on which a paint spraying mechanism and a heating mechanism are provided, wherein the paint spraying mechanism's paint nozzle is mostly located at the bottom of the construction vehicle. The construction vehicle moves along the extension direction of the road, and the heating mechanism heats the paint spraying mechanism, so that the dye sprayed from the paint spraying mechanism's paint nozzle can be quickly solidified on the road after being heated to form a road marking.

[0004] However, when a construction vehicle is laying road markings on a road, there is a phenomenon that the paint nozzle of the paint spraying mechanism is hit and damaged by the convex parts of the road, which greatly affects the normal use of the construction vehicle, so there is room for improvement. Summary of the invention

[0005] In order to improve the problem that the paint spraying tube of the paint spraying mechanism is easily damaged by being hit by the convex parts of the road, the present application provides a reactive road marking automatic unmanned construction equipment.

[0006] The reactive road marking automatic unmanned construction equipment provided in this application adopts the following technical solutions:

[0007] Reactive road marking automatic unmanned construction equipment includes a construction body, on which is disposed a paint spray pipe for laying road markings on a road, and also includes an early warning mechanism and a protective mechanism; the early warning mechanism includes an impact component and a receiving component, the impact component is disposed on the construction body through the receiving component, the impact component is used to receive the impact of a protruding part of the road, so as to be displaced relative to the construction body through the receiving component; the protective mechanism includes an auxiliary spray component and an adjustment component, the adjustment component is disposed on the construction body, and the auxiliary spray component is disposed on the paint spray pipe through the adjustment component; the adjustment component is also electrically connected to the receiving component, so as to control the displacement of the auxiliary spray component relative to the paint spray pipe.

[0008] By adopting the above technical scheme, the impact assembly is installed on the construction body through the receiving assembly. When the construction body encounters a protruding part of the road during operation, the impact assembly abuts against the protruding part of the road to bear the impact force, which helps to reduce the damage to the construction body and the paint nozzle after the impact; the auxiliary spray assembly is used to protect the paint nozzle to reduce the direct collision of the paint nozzle by the protruding part of the road; in addition, the receiving assembly can send an electrical signal to the adjustment assembly after the impact assembly is collided, so that the adjustment assembly controls the auxiliary spray assembly to move toward the construction body, while ensuring the normal operation of the construction body through the paint nozzle, reducing the collision between the auxiliary spray assembly and the protruding part of the road, which helps to ensure the application safety of the paint nozzle and ensure the stability of the construction body for long-term application.

[0010] By adopting the above technical scheme, the force-bearing unit is arranged on the receiving plate through all the shock-absorbing parts, so that the force-bearing unit can directly offset the protruding part of the road, thereby reducing the phenomenon of damage caused by the collision between the paint nozzle and the protruding part of the road; when the force-bearing unit collides with the protruding part of the road, the shock-absorbing part is compressed to absorb part of the impact force, and the displacement plate is displaced relative to the receiving plate, thereby offsetting part of the impact force; in addition, the elastic force generated during the compression of the shock-absorbing part can react on the force-bearing unit, thereby reducing the impact intensity on the construction machine body and the paint nozzle; after the force-bearing unit is impacted, the early warning unit sends an electrical signal to the adjusting component, so that the adjusting component controls the displacement of the auxiliary spray component, thereby reducing the phenomenon of damage caused by the collision between the auxiliary spray component and the protruding part of the road again.

The shock-absorbing block can absorb part of the impact force through its own deformation to reduce the phenomenon that the load-bearing plate and the load-unloading module are directly damaged after the impact.

[0015] In a specific feasible implementation scheme, the early warning unit includes a directional pillar and an early warning plate, one end of the directional pillar is arranged on the receiving plate, and the other end of the directional pillar is passed through the edge detection plate; the early warning plate is arranged at the end of the directional pillar away from the receiving plate, and the early warning plate and the edge detection plate are gap-fitted or abutted.

[0016] By adopting the above technical solution, the directional pillar passes through the edge probe plate to limit the direction of displacement of the edge probe plate. When the shock-absorbing component is compressed and deformed to a certain extent, the edge probe plate and the early warning plate are offset, causing the early warning plate to send an electrical signal to the adjustment component, and then the auxiliary spraying component is controlled to move toward the construction body through the adjustment component to reduce the collision between the auxiliary spraying component and the protruding part of the road.

[0017] In a specific possible implementation scheme, the impact assembly also includes a stop unit, which includes a plug-in plate, a side wing plate and a stop bolt; the side wing plate is arranged on the plug-in plate, and the shift plate is provided with a plug-in groove for inserting one end of the plug-in plate, and the plug-in plate is abutted against the receiving plate; the stop bolt is used to position the side wing plate on the shift plate.

[0018] By adopting the above technical scheme, the plug-in board is plugged into the inner cavity of the plug-in slot to abut against the receiving plate, thereby limiting the position of the shift plate relative to the receiving plate and reducing the phenomenon of free displacement of the shift plate relative to the receiving plate; the side wing plate increases the contact area between the plug-in board and the shift plate, and after the plug-in board and the shift plate are fixedly connected by the position bolts, the position stability of the plug-in board in the inner cavity of the plug-in slot is guaranteed.

[0019] In a specific feasible implementation scheme, the auxiliary spray assembly includes a connecting tube and a marking nozzle, the marking nozzle is arranged at one end of the connecting tube and is connected to the inner cavity of the connecting tube, and the other end of the connecting tube is sleeved on the paint nozzle; the adjustment assembly includes a docking frame, a propeller and an outer edge support plate, the outer edge support plate is arranged around the outer peripheral wall of the connecting tube, the propeller is arranged on the construction body through the docking frame, and the output end of the propeller is connected to the outer edge support plate.

[0020] By adopting the above technical scheme, the connecting tube is sleeved on the paint nozzle, so that the construction body sprays paint outward through the marking nozzle to form marking lines on the road; the output end of the propulsion member is connected to the outer edge support plate, which ensures the stability of the connecting tube sleeved on the paint nozzle; the output end of the propulsion member extends outward, so that the connecting tube and the marking nozzle are displaced toward the construction body, reducing the phenomenon of the connecting tube and the marking nozzle being damaged by collision with protruding parts of the road.

[0021] In a specific feasible implementation scheme, the adjustment assembly also includes a guide unit, which includes a pre-alignment rod and an auxiliary connecting tube; the auxiliary connecting tube is arranged on the outer edge support plate, the pre-alignment rod is arranged on the construction body, and one end of the pre-alignment rod close to the auxiliary connecting tube abuts and fits in the side wall of the auxiliary connecting tube.

[0032] The embodiments of the present application disclose reactive road marking automatic unmanned construction equipment.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] Reference Figure 1 The reactive road marking automatic unmanned construction equipment includes a construction body 1, an early warning mechanism 2 and a protective mechanism 3. The construction body 1 can be a road marking construction vehicle, and a paint nozzle 11 is arranged on the bottom wall of the construction body 1 in the vertical direction. The construction body 1 sprays dye outward through the paint nozzle 11 to form road markings on the road. The early warning mechanism 2 and the protective mechanism 3 are both arranged on the bottom wall of the construction body 1, wherein the early warning mechanism 2 is located on one side of the paint nozzle 11 to bear the impact of the protruding part of the road, thereby playing the role of protecting the paint nozzle 11. The protective mechanism 3 is used to protect the paint nozzle 11 to reduce the phenomenon that the paint nozzle 11 is damaged by the impact of the protruding part of the road.

[0035] Reference Figure 2The warning mechanism 2 includes an impact component 4 and a receiving component 5, wherein the receiving component 5 includes a receiving plate 51. The receiving plate 51 is welded to the bottom wall of the construction machine body 1 in a vertical direction, and the receiving plate 51 is located between the dye spraying pipe and the two front wheels of the construction machine body 1.

[0036] Reference Figure 2 and Figure 3 The impact assembly 4 includes a force-bearing unit 41, a shift plate 42, an edge detection plate 43 and a plurality of groups of shock-absorbing components 44, wherein the force-bearing unit 41 further includes a force-bearing plate 411. In the present embodiment, the force-bearing plate 411 may be a solid steel plate, and the shock-absorbing component 44 may be a steel compression spring. The same end in the length direction of all the shock-absorbing components 44 is welded to the side wall of the receiving plate 51 away from the dye nozzle, the force-bearing plate 411 is welded to one end of all the shock-absorbing components 44 away from the receiving plate 51, and one end of the force-bearing plate 411 away from the construction machine body 1 is located below one end of the receiving plate 51 away from the construction machine body 1. When the construction machine body 1 encounters a protruding part of the road during road construction, the force-bearing plate 411 may first abut against the protruding part of the road to reduce the phenomenon that the protruding part of the road hits the dye nozzle and causes damage to the dye nozzle. The shock absorbing member 44 can be compressed and deformed after the load-bearing plate 411 is subjected to force, and react to the load-bearing plate 411 through the elastic force generated when the shock absorbing member 44 is compressed, so as to reduce the impact strength of the load-bearing plate 411 .

[0037] Reference Figure 3 , the over-displacement plate 42 is welded to the side wall of the bearing plate 411 facing the receiving plate 51 in the horizontal direction, and the side wall of the over-displacement plate 42 facing the construction machine body 1 is in the same horizontal plane as the end wall of the bearing plate 411 facing the construction machine body 1. The end of the over-displacement plate 42 away from the bearing plate 411 is penetrated through the receiving plate 51, and the side probe plate 43 is welded to the end of the over-displacement plate 42 away from the bearing plate 411 in the vertical direction. When the bearing plate 411 collides with the protruding part of the road, the over-displacement plate 42 can be displaced relative to the receiving plate 51 to unload part of the impact force on the bearing plate 411.

[0038] Reference Figure 3 In order to reduce the phenomenon that the over-displacement plate 42 is freely displaced relative to the receiving plate 51 when the shock absorbing member 44 is in a freely extended state, the impact assembly 4 further includes a stop unit 45. The stop unit 45 includes a plug-in plate 451, a side wing plate 452 and a stop bolt 453, wherein the side wing plate 452 is vertically welded to the plug-in plate 451. The side wall of the over-displacement plate 42 facing the construction machine body 1 is provided with a plug-in slot 421, and the inner diameter of the plug-in slot 421 is adapted to the outer circumference of the plug-in plate 451.

[0039] Reference Figure 3After one end of the plug-in plate 451 is inserted into the inner cavity of the plug-in slot 421, the side wall of the plug-in plate 451 away from the side wing plate 452 abuts against the receiving plate 51, and the bottom wall of the side wing plate 452 abuts against the top wall of the over-displacement plate 42. The operator can pass the stop bolt 453 through the side wing plate 452 and screw it into the preset thread groove on the top wall of the over-displacement plate 42 to fix the side wing plate 452 and the over-displacement plate 42, thereby making the plug-in plate 451 abut against the receiving plate 51 to reduce the phenomenon of free displacement of the over-displacement plate 42 relative to the receiving plate 51.

[0040] Reference Figure 3 and Figure 4 In order to improve the impact resistance of the load-bearing plate 411 and the force unloading stability of the displacement of the transfer plate 42 relative to the receiving plate 51, the force-bearing unit 41 also includes a shock-absorbing block 412 and a force unloading module 413, wherein the force unloading module 413 further includes a guide arc plate 4131, multiple groups of pulling steel cables 4132 and multiple force unloading rollers 4133.

[0041] Reference Figure 3 In this embodiment, the shock absorbing block 412 can be a rubber block with willfulness and easy deformation, and the shock absorbing block 412 is bonded to the end wall of the bearing plate 411 away from the construction machine body 1 by glue. The guide arc plate 4131 is bonded to the side wall of the shock absorbing block 412 away from the bearing plate 411 by glue, and the two ends of the guide arc plate 4131 in the length direction extend to the opposite sides of the shock absorbing block 412 respectively. One end of the pulling steel cable 4132 in the length direction is welded to the outer side wall of the bearing plate 411, and the other end of the pulling steel cable 4132 in the length direction is welded to the guide arc plate 4131, so that the parts of the guide arc plate 4131 located on both sides of the shock absorbing block 412 are connected to the bearing plate 411.

[0042] Reference Figure 4 In this embodiment, the unloading roller 4133 may be a roller, and each unloading roller 4133 is rotatably disposed on the side wall of the guide arc plate 4131 away from the shock absorbing block 412 through a rotating shaft.

[0043] Reference Figure 3 and Figure 4 When the construction machine 1 is running on a flat road, all the unloading rollers 4133 are in a suspended state. When the construction machine 1 encounters a protruding part of the road, the unloading rollers 4133 abut against the protruding part of the road and rotate rapidly, and the shock absorbing block 412 is compressed and deformed by the thrust of the guide arc plate 4131, absorbing part of the impact force and causing the bearing plate 411 to move relative to the receiving plate 51 through the shock absorbing member 44, and the over-displacement plate 42 to move relative to the receiving plate 51, thereby reducing the phenomenon of the bearing plate 411 being damaged by direct collision with the protruding part of the road, and improving the shock absorbing and impact resistance of the construction machine 1, which helps to ensure the long-term stable application of the paint spraying pipe 11.

[0044] Reference Figure 2 The protection mechanism 3 includes an auxiliary spray assembly 6 and an adjustment assembly 7, wherein the auxiliary spray assembly 6 includes a connecting tube 61 and a marking nozzle 62. In the present embodiment, the connecting tube 61 can be a cylinder whose inner diameter size is adapted to the outer diameter size of the paint nozzle 11, and the marking nozzle 62 is integrally formed at one end of the connecting tube 61 in the length direction. The end of the connecting tube 61 away from the marking nozzle 62 is sleeved on the paint nozzle 11, so that the construction body 1 sprays dye outward through the marking nozzle 62 to form road markings on the road. In addition, the provision of the connecting tube 61 and the marking nozzle 62 reduces the protruding length of the paint nozzle 11 at the bottom of the construction body 1, which helps to reduce the phenomenon of damage caused by the collision between the paint nozzle 11 and the protruding part of the road.

[0045] Reference Figure 2 The adjustment component 7 is used to ensure the connection stability of the connecting tube 61 on the paint nozzle 11, and can control the displacement of the connecting tube 61 relative to the paint nozzle 11. The adjustment component 7 includes a docking frame 71, a pusher 72 and an outer edge support plate 73, wherein the docking frame 71 can be an L-shaped plate, the docking frame 71 is welded to the bottom wall of the construction machine body 1, and the docking frame 71 is located at one end of the paint nozzle 11 away from the receiving plate 51. The pusher 72 can be an electric cylinder, the pusher 72 is vertically penetrated and welded to the docking frame 71, and the output end of the pusher 72 is arranged toward the construction machine body 1. The outer edge support plate 73 is integrally formed on the outer peripheral wall of the connecting tube 61, and the bottom wall of the outer edge support plate 73 is welded to the output end of the pusher 72. When the output end of the pusher 72 is in a contracted state, the output end of the pusher 72 ensures the stability of the connecting tube 61 being sleeved on the paint nozzle 11 by receiving the outer edge support plate 73. When the pusher 72 extends outward from the output end, the connecting tube 61 drives the line marking nozzle 62 to move toward the construction machine body 1 to reduce the collision between the line marking nozzle 62 and the road nozzle, thereby helping to ensure the application stability of the line marking nozzle 62.

[0046] Reference Figure 2 and Figure 3 In order to make the output end of the pusher 72 automatically push the connecting tube 61 to move, the receiving assembly 5 also includes an early warning unit 52, which includes a directional support 521 and an early warning plate 522. Among them, one end of the directional support 521 in the length direction is welded to the side wall of the receiving plate 51 away from the bearing plate 411 in the horizontal direction, and the other end of the directional support 521 in the length direction is penetrated through the edge detection plate 43.

[0047] Reference Figure 2 and Figure 3In this embodiment, the warning plate 522 is a probe plate with a PLC controller inside. The outer circumference of the warning plate 522 is larger than the outer diameter of the directional pillar 521. The warning plate 522 is glued to the end wall of the directional pillar 521 away from the receiving plate 51 by glue, and the warning plate 522 is electrically connected to the propeller 72 through wires. When the shock-absorbing member 44 is in a free extension state, there is a clearance fit between the side probe plate 43 and the warning plate 522. When the shock-absorbing member 44 is compressed and deformed to a certain extent, the side probe plate 43 moves with the over-displacement plate 42 and abuts against the warning plate 522. At this time, the warning plate 522 sends an electrical signal to the propeller 72 through the wire, so that the propeller 72 extends the output end, and then the connecting tube 61 and the marking nozzle 62 are displaced toward the construction body 1, so as to reduce the phenomenon that the marking nozzle 62 is damaged by collision with the protruding part of the road.

[0048] Reference Figure 2 In order to ensure the displacement stability of the connecting tube 61 and the marking nozzle 62, the adjustment assembly 7 also includes a guide unit 74. The guide unit 74 includes a pre-direction rod 741 and an auxiliary connecting tube 742. In this embodiment, the outer circumference of the pre-direction rod 741 is matched with the inner diameter of the auxiliary connecting tube 742. The pre-direction rod 741 is welded to the bottom wall of the construction machine body 1 in the vertical direction, and the auxiliary connecting tube 742 is welded to the outer edge support plate 73 in the vertical direction. The central axis of the pre-direction rod 741 is colinear with the central axis of the auxiliary connecting tube 742, and one end of the pre-direction rod 741 close to the auxiliary connecting tube 742 abuts against the side wall of the auxiliary connecting tube 742. When the output end of the propulsion member 72 extends outward to cause the connecting tube 61 to drive the marking nozzle 62 to move, the side wall of the auxiliary connecting tube 742 provides lateral support to the pre-rod 741 to limit the displacement direction of the connecting tube 61 and the marking nozzle 62 relative to the paint nozzle 11, thereby ensuring the displacement stability of the connecting tube 61 and the marking nozzle 62.

[0049] The implementation principle of the reactive road marking automatic unmanned construction equipment of the embodiment of the present application is as follows: when the construction machine body 1 encounters a protruding part of the road during operation, the guide arc plate 4131 rotates on the protruding part of the road through the unloading roller 4133 to reduce the phenomenon of the guide arc plate 4131 directly contacting the protruding part of the road. At the same time, the shock absorbing block 412 is compressed and deformed by the pressure of the guide arc plate 4131, the bearing plate 411 is displaced toward the receiving plate 51 after being stressed, and the shock absorbing member 44 is compressed and deformed after being stressed, and drives the over-displacement plate 42 and the side probe plate 43 to displace relative to the receiving plate 51.

[0050] During this process, the shock-absorbing block 412 and the shock-absorbing member 44 absorb the impact force exerted on the guide arc plate 4131 through their own compression deformation. The elastic force generated when the shock-absorbing member 44 is compressed reacts to the guide arc plate 4131, and cooperates with the displacement of the shift plate 42 relative to the receiving plate 51 to further reduce the impact intensity exerted on the construction body 1, thereby helping to protect the paint nozzle 11, the connecting nozzle and the marking nozzle 62, and ensuring the application stability of the construction body 1.

[0051] When the shock-absorbing member 44 is compressed to a certain extent, the edge detection plate 43 and the warning plate 522 are against each other, and the warning plate 522 sends an electrical signal to the propulsion member 72 through the wire, so that the propulsion member 72 extends outward from the output end. After the propulsion member 72 extends outward from the output end, the outer edge support plate 73 drives the connecting tube 61 and the marking nozzle 62 to move toward the construction machine body 1, so as to reduce the phenomenon that the connecting tube 61 and the marking nozzle 62 are damaged by the protruding part of the road at a lower position, thereby helping to ensure the stability of the construction machine body 1 for long-term use.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
