[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. When sorting materials, the present invention adopts an inclined inclined bottom plate and two side plates to enclose a material sorting channel for the safety spikes to move inside, and a nail rod groove is opened in the middle of the inclined bottom plate for the nail rod to fall into so that the indicator cap is hung on the inclined bottom plate and moves forward along the feeding direction. Since the material sorting track vibrates through the straight vibrator to make the safety spikes vibrate and move, the inclined inclined bottom plate is convenient for the safety spikes to slide down along the inclined bottom plate under their own gravity when vibrating and moving, so that the nail rods placed on the inclined bottom plate fall into the nail rod grooves to achieve the initial material sorting. After the initial material sorting, the safety spikes whose nail rods have not fallen into the nail rod grooves continue to vibrate and move forward, and drop rod grooves that are connected to the nail rod grooves are respectively provided on both sides of the nail rod groove on the inclined bottom plate, and the front side walls of the drop rod grooves in the moving direction of the safety spikes are provided with guide angles in the oblique moving direction. When the nail rods placed on the inclined bottom plate pass through the drop rod grooves, the nail rods are moved from When the safety spike falls into the drop rod groove on the inclined bottom plate, if the indicator cap is also placed on the inclined bottom plate, the nail rod will slide out of the nail rod groove along the guide angle during the forward movement of the vibration, and the indicator cap will flip toward the inclined bottom plate and finally hang on the inclined bottom plate, completing the secondary material sorting; when the safety spike is placed upside down on the inclined bottom plate with the nail rod facing upward, the safety spike will be blocked by the baffle when it moves to the baffle and will slide out of the sliding outlet during the vibration of the material sorting track, and will be caught by the return device and returned to the storage hopper or the transfer device to flow back to the material sorting track for material sorting; and those safety spikes whose nail rods fall into the nail rod grooves and whose indicator caps are hung on the inclined bottom plate will pass through the screening port and flow through the guiding track, and the inclined safety spikes will be corrected by the guiding track and then input into the feeding device, and will be sorted and fed in the feeding device, with a simple structure, automatic material sorting and sorting feeding of the safety spikes can be realized, and the material sorting efficiency is high.

[0016] 2. When sorting materials, the present invention drives the storage hopper to vibrate through the direct vibrator below the storage hopper and makes the safety spikes inside flow out from the discharge port to the transfer track. The direct vibrator below the transfer track drives the transfer track to vibrate and makes the safety spikes inside the transfer track move toward one end of the material sorting track. When the safety spikes in the transfer track are piled up up and down, when passing through the sweeping device, the sweeping device sweeps back the safety spikes piled on the upper layer, and the lower layer safety spikes located below the sweeping device flow into the material sorting track after passing through the through port, so as to avoid the accumulation of safety spikes falling into the material sorting track for material sorting, thereby improving the material sorting efficiency of the material sorting track.

[0017] 3. The nail rod groove of the present invention is larger at the top and smaller at the bottom, and the lower part is only for the nail rod to fall into, while preventing the sideways indicator cap from falling in. A type of safety spike located at the starting end of the material sorting track has its nail rod resting on the edge of the inclined bottom plate close to the nail rod groove. When it vibrates forward on the material sorting track, the nail rod can easily and quickly fall into the nail rod groove during the vibration process, thereby improving the initial material sorting efficiency. In addition, when the safety spike with one side of the indicator cap falling into the nail rod groove vibrates forward, when passing through the drop-rod groove, under the deadweight of the safety spike, the nail rod falls from the inclined bottom plate into the drop-rod groove, and under the guiding action of the guide angle, the safety spike flips over, the upper end of the indicator cap flips down, and the lower end tilts up, until the indicator cap flips over and falls on the inclined bottom plate, and the nail rod slides out of the drop-rod groove along the guide angle into the nail rod groove, thereby preventing the safety spike with the indicator cap falling sideways into the nail rod groove from being unable to sort materials or getting stuck, thereby improving the material sorting efficiency.

[0018] 4. The drop rod grooves on both sides of the nail rod groove of the present invention are staggered so that the safety spikes in the material handling channel can move forward smoothly by vibration.

[0019] 5. The present invention is also provided with a sensor and a rotating device. Since the reflective surface of the safety road spike is not all on each side of the indicator cap, the sensor is used to detect whether the reflective surface of the safety road spike on the conveyor belt is in the set direction. If not, the rotating device is used to drive the safety road spike to rotate a certain angle so that the reflective surface is adjusted to the set direction, thereby preventing the safety road spike installed on the road from losing the reflective effect in the corresponding direction and failing to function.

[0040] The side door body 14 is a sliding door slidably connected to the rear compartment 12, and the door body opening and closing device can be driven by a cylinder, or by a motor combined with a gear and a rack.

[0041] The rear compartment 12 is used to carry the sorting and conveying mechanism 3, the drilling mechanism, the nail removing mechanism and the hammering mechanism. During construction, the side door 13 is opened by automatically moving the side door body 14. Driven by the position moving device 7, the vertical drilling device 4, the clamping device 5 and the hammering device 6 extend out of the rear compartment 12 from the side door 13 and lean against the road surface for construction. Then, work can be carried out even on rainy days to avoid delays in construction progress due to weather influences. At the same time, the sorting and conveying mechanism 3, the drilling mechanism, the nail removing mechanism and the hammering mechanism can be prevented from being exposed to the sun and rain, thereby increasing their service life.

[0042] like Figures 2 to 5As shown, the position moving device 7 includes a transverse guide rod 71 arranged along the front-rear direction of the vehicle body, and three frames 72 are slidably connected to the transverse guide rod 71, and each of the frames 72 is slidably connected to a longitudinal guide rod 73, and a protruding frame 74 located on one side of the side door 13 is fixed to the longitudinal guide rod 73 corresponding to each frame 72, and spur racks 75 are respectively arranged on the transverse guide rod 71 and the longitudinal guide rod 73 along the axial direction of the two, and each of the frames 72 is provided with two sets of gears 76 respectively meshing with the spur racks 75 in the longitudinal and transverse directions, and the two sets of gears 76 are respectively driven by the corresponding gears 76.

The extension frame 74 is also provided with a screw rod for driving The screw motor 712 rotates the screw rod 710, and a lifting cylinder 713 is fixed on the adjustment seat 79 for driving the lifting seat 78 to move up and down. The three lifting seats 78 are respectively used to install the vertical drilling device 4, the clamping device 5 and the hammering device 6, thereby respectively realizing the three-axis movement of the vertical drilling device 4, the clamping device 5 and the hammering device 6; and in the process of moving up and down, the lifting seat 78 is driven to move up and down by the lifting cylinder 713, thereby realizing the rapid lifting of the vertical drilling device 4, the clamping device 5 and the hammering device 6, and the screw rod 710 is driven to rotate by the screw motor 712 The adjusting seat 79 and the lifting seat 78 are driven to rise and fall, so as to realize the up and down fine adjustment of the vertical drilling device 4, the clamping device 5 and the hammering device 6. At the beginning of construction, the positions of the vertical drilling device 4, the clamping device 5 and the hammering device 6 are first fine-adjusted up and down according to the situation, so that the vertical drilling device 4, the clamping device 5 and the hammering device 6 can be located in the processing position when they are quickly lowered under the drive of the lifting cylinder 713. During construction, it is only necessary to control the lifting cylinder 713 to drive the vertical drilling device 4, the clamping device 5 and the hammering device 6 to rise and fall to realize normal construction, so as to adapt to different road conditions and carry out rapid construction.

[0043] like Figure 3 The vertical drilling device 4 includes a drill bit 41, a spindle 42, and a spindle driving device for driving the spindle 42 to feed and rotate.

The hammering device 6 includes an impact hammer head 61 and an impact cylinder 62 for driving the impact hammer head 61 to impact downward.

[0044] like Figures 6 to 12As shown, the sorting and conveying mechanism 3 includes a storage hopper 31, a material sorting track 32 and a feeding device 33. The storage hopper 31 is provided with a discharge port 311 for the safety spikes 10 therein to flow out. A transfer device 34 is provided between the storage hopper 31 and the material sorting track 32, which can receive the safety spikes 10 flowing out of the discharge port 311 and send them into the material sorting track 32. Straight vibrators 35 for driving the storage hopper 31 and the material sorting track 32 to vibrate and move the safety spikes 10 therein are provided below the storage hopper 31 and the material sorting track 32 respectively; the material sorting track 32 includes an inclined bottom plate 321 and side plates located on both sides of the inclined bottom plate 321 322, the inclined bottom plate 321 is inclined from one side plate 322 to the other side plate 322, and the three of them form a material sorting channel 320 for the safety road spike 10 to move in. A nail rod groove 323 is provided in the middle of the inclined bottom plate 321 for the nail rod 1B to fall into so that the indicator cap 1A is hung on the inclined bottom plate 321 and moves. The nail rod groove 323 allows the nail rod 1B that falls into it to move along the feeding direction of the material sorting track 32. The inclined bottom plate 321 is provided with drop rod grooves 324 that are connected to the nail rod groove 323 on both sides of the nail rod groove 323. The drop rod grooves 324 allow the nail rod 1B placed on the inclined bottom plate 321 to move along the feeding direction of the material sorting track 32. When the safety spike 10 passes through the drop rod groove 324, it falls from the inclined bottom plate 321. The drop rod groove 324 is located at the front side of the moving direction of the safety spike 10 and is provided with a guide angle 325 that can guide the nail rod 1B in the drop rod groove 324 into the nail rod groove 323. The end of the material sorting track 32 is provided with a baffle 326. A screening port 327 is provided between the baffle 326 and the material sorting track 32 for only the safety spike 10 with the indicator cap 1A hanging on the inclined bottom plate 321 to pass through. A guide port 327 is provided between the screening port 327 and the feeding device 33 for guiding the safety spike 10 screened out of the screening port 327 from the inclined state and then inputting it into the feeding device 33. The main track 328, the feeding device 33 is used to supply the safety spikes 10 to the spike removal mechanism in an orderly manner, and a sliding outlet 329 is provided on the side plate 322 located on the lower side of the inclined bottom plate 321. The sliding outlet 329 is close to the baffle 326 and allows the safety spikes 10 blocked by the baffle 326 in the material sorting track 32 to slide out. A return device 36 is provided below the material sorting track 32 for catching the safety spikes 10 that have not flowed out of the screening port 327 and fallen from the material sorting track 32 and returning the safety spikes 10 to the transfer device 34. Of course, the return device 36 can also return the safety spikes 10 back to the storage hopper 31.

[0045] When sorting materials, a sorting channel 320 for the safety spike 10 to move in is formed by using an inclined bottom plate 321 and two side plates 322, and a nail rod groove 323 is opened in the middle of the inclined bottom plate 321, so that the nail rod 1B can fall into it, so that the indicator cap 1A is hung on the inclined bottom plate 321 and moves forward along the feeding direction. Since the sorting track 32 vibrates through the straight vibrator 35 to vibrate and move the safety spike 10, the inclined bottom plate 321 facilitates the safety spike 10 to slide down along the inclined bottom plate 321 under its own gravity when it vibrates and moves, so that it is convenient to rest on the inclined bottom plate The nail rod 1B on the slanted bottom plate 321 falls into the nail rod groove 323 to achieve the initial material sorting; after the initial material sorting, the safety spike 10 in which the nail rod 1B does not fall into the nail rod groove 323 continues to vibrate forward, and the nail rod groove 324 communicating with the nail rod groove 323 is respectively provided on both sides of the slanted bottom plate 321, and the front side wall of the nail rod groove 324 located in the moving direction of the safety spike 10 is provided with a guide angle 325 in the oblique moving direction, when the nail rod 1B resting on the slanted bottom plate 321 passes through the nail rod groove 324, the nail rod 1B is moved from the slanted bottom plate When the safety spike 10 is placed upside down on the inclined bottom plate 321 with the nail rod 1B facing upward, it will be blocked by the baffle 326 when it moves to the baffle plate 326 and will slide out from the slide outlet 329 during the vibration of the material sorting track 32 and will be returned to the material sorting device 32. After being caught by the device 36, it returns to the storage hopper 31 or the transfer device 34 to flow to the material sorting track 32 for sorting again; and the safety spikes 10 whose nail rods 1B fall into the nail rod grooves 323 and whose indicator caps 1A are hung on the inclined bottom plate 321 pass through the screening port 327 and flow through the guiding track 328. The inclined safety spikes 10 are corrected by the guiding track 328 and then input into the feeding device 33, and are sorted and fed in the feeding device 33. The structure is simple, and automatic sorting and sorting of the safety spikes 10 are realized, and the material sorting efficiency is high.

[0046] The nail rod groove 323 is larger at the top and smaller at the bottom, and the bottom portion is only for the nail rod 1B to fall into, and prevents the indicator cap 1A placed sideways from falling into. Fig.10 The safety spike 10 shown is located at the starting end of the material sorting track 32, and its spike rod 1B is placed on the edge of the inclined bottom plate 321 near the spike rod groove 323. When it vibrates forward on the material sorting track 32, the spike rod 1B can easily and quickly fall into the spike rod groove 323 during the vibration process, thereby improving the material sorting efficiency. Fig. 9As shown, when the safety road spike 10 with one side of the indicator cap 1A falling into the nail rod groove 323 moves forward by vibration, when passing through the rod drop groove 324, under the deadweight of the safety road spike 10, the nail rod 1B falls from the inclined bottom plate 321 into the rod drop groove 324, and under the guidance of the guide angle 325, the safety road spike 10 turns over, the upper end of the indicator cap 1A turns downward, and the lower end tilts upward, until the indicator cap 1A turns over and falls on the inclined bottom plate 321, and the nail rod 1B slides out of the rod drop groove 324 along the guide angle 325 into the nail rod groove 323, thereby preventing the safety road spike 10 with the indicator cap 1A falling sideways into the nail rod groove 323 from being unable to sort or getting stuck, thereby improving the material sorting efficiency.

[0047] The two side walls and the top surface of the inclined bottom plate 321 constituting the nail rod groove 323 have a smooth transition, which is conducive to the indicator cap 1A falling sideways into the nail rod groove 323 to turn up.

[0048] The drop rod grooves 324 on both sides of the nail rod groove 323 are staggered so that the safety spikes 10 in the material handling channel 320 can move forward smoothly by vibration.

[0049] The width d of the bottom of the material sorting channel 320 is greater than the side length a of the indicator cap 1A and smaller than the outer diameter b of the indicator cap 1A, which is convenient for limiting and guiding the position of the safety spike 10 and improving the material sorting efficiency of the material sorting track 32 .

[0050] The return device 36 is disposed below the slide outlet 329 and is used to receive the safety spike 10 that slides out of the slide outlet 329 and return the safety spike 10 back.

[0051] The return device 36 includes a climbing bracket 361 that tilts up and down, and a climbing conveyor belt 362 and a climbing motor 363 that drives the climbing conveyor belt 362 to move are provided on the climbing bracket 361. A plurality of baffle plates 364 that can prevent the safety spikes 10 from sliding down on the climbing conveyor belt 362 are arranged at intervals along the climbing direction. The lower end of the climbing conveyor belt 362 is located below the sliding outlet 329 and can receive the safety spikes 10 that slide out of the sliding outlet 329, and the upper end extends into the transfer device 34, and of course can also extend into the storage hopper 31.

[0052] Of course, when the material sorting track 32 drops the safety spike 10 that cannot be sorted, in addition to sliding out from the sliding outlet 329, the width of the nail rod groove 323 can also be set to allow the sideways indicator cap 1A to fall, so that a falling groove is formed at the drop rod groove 324 for the safety spike 10 to fall sideways out of the material sorting track 32, and the indicator cap 1A falls sideways into the nail rod groove 323 while the nail rod 1B is resting on the inclined bottom plate 321. When it moves to the drop rod groove 324, the safety spike 10 falls from there; correspondingly, the return device 36 is arranged below the sliding outlet 329 and the drop rod groove 324 and is used to receive the safety spike 10 that slides out from the sliding outlet 329 and the drop rod groove 324 and then return the safety spike 10 (omitted in the figure).

[0053] like Fig.11 As shown, the feeding device 33 includes a conveyor belt, and the conveyor belt includes a belt 331, a pulley 332 and a belt motor 333. The belt 331 is installed on the pulley 332. The belt motor 333 is directly or indirectly connected to the pulley 332 and drives the pulley 332 to rotate. The belt 331 has two belts and is arranged at intervals for the nail rod 1B to pass through. The safety spike 10 is hung on the two belts 331 and moves with the belts. A limit plate 334 is provided between the two belts 331, which can block the safety spike 10 from the front in the moving direction so as to limit the safety spike 10 on the belt 331 from continuing to move. The feeding device 33 also includes a sensor 335 that can detect the position of the reflective surface 1C on the safety spike 10, and a rotating device 336 that can lift the safety spike 10 on the belt 331 and rotate it a certain angle so that the reflective surface 1C is adjusted to a set orientation. The sensor 335 and the rotating device 336 are electrically connected to the control system.

[0054] Since the reflective surface 1C on the safety road spike 10 is not on every side of the indicator cap 1A, the sensor 335 is used to detect whether the reflective surface 1C of the safety road spike 10 on the conveyor belt is in the set direction. If not, the rotating device 336 is used to drive the safety road spike 10 to rotate a certain angle so that the reflective surface 1C is adjusted to the set direction, thereby preventing the safety road spike 10 installed on the road from losing the reflective effect in the corresponding direction and becoming ineffective.

[0055] like Fig.12 As shown, the rotating device 336 includes a supporting member 3361 capable of lifting and rotating the safety spike 10 on the belt 331, a lifting cylinder 3362 for driving the supporting member 3361 to rise and fall, and a rotating cylinder 3363 for driving the supporting member 3361 to rotate. The lifting cylinder 3362 drives the supporting member 3361 to first lift the safety spike 10 from the belt 331, and then the rotating cylinder 3363 drives the supporting member 3361 to rotate with the safety spike 10.

[0056] The transfer device 34 includes a transfer track 341, one end of which is located below the discharge port 311, and the other end is located above the starting end of the material handling track 32. A straight vibrator 35 is provided below the transfer track 341 for driving the transfer track 341 to vibrate and move the safety spikes 10 in the transfer track 341 toward the material handling track 32. A sweeping device 342 is provided on the transfer track 341 for sweeping back the safety spikes 10 accumulated on the upper layer. A through hole 343 is left between the transfer track 341 and the sweeping device 342 for the safety spikes 10 on the lower layer to pass through and flow into the material handling track 32. The transfer track 341 is driven to vibrate and feed materials by the straight vibrator 35, and the accumulated safety spikes 10 are swept back by the sweeping device 342, thereby preventing the safety spikes 10 from accumulating up and down and flowing toward the material handling track 32, thereby improving the material handling efficiency of the safety spikes 10 in the material handling track 32.

[0057] The sweeping device 342 includes a sweeping wheel 3421 having a plurality of blades 3422 and a sweeping motor 3423 for driving the sweeping wheel 3421 to rotate. The sweeping wheel 3421 spans over the transfer track 341 and allows the safety spikes 10 located below it to pass through. The sweeping motor 3423 drives the sweeping wheel 3421 to rotate back and sweep back the safety spikes 10 it encounters.

[0058] A method for installing safety road spikes using the fully automatic road spike installation vehicle comprises the following steps:

[0059] A. Drive the fully automatic safety road stud construction vehicle to the construction road with lane markings;

[0060] B. The lane marking lines on the road surface are photographed by the camera 2 and fed back to the control system to determine the position of the lane marking lines and calculate the installation position of the safety road studs 10;

[0061] C. Driven by the position moving device 7, the vertical drilling device 4 moves to the road surface above the safety road spike installation position and drills holes on the road surface. After drilling the holes, the vertical drilling device 4 moves away; the clamping device 5 moves to the sorting and conveying mechanism 3 to grab the safety road spike 10 sorted by the sorting and conveying mechanism 3 and moves to the installation position, presses down the safety road spike 10 to insert the nail rod 1B downward into the drilled hole, and then the clamping device 5 releases the safety road spike 10 and moves away; the hammering device 6 moves to the top of the safety road spike 10 and hammers the indicator cap 1A downward to nail the safety road spike 10 firmly on the road surface;

[0062] D. The control system controls the fully automatic road stud installation vehicle to move forward along the lane marking line and stop at a distance equal to the distance between two adjacent road studs 10 according to the detected lane marking line, and repeats the above steps B to C to install the road stud 10 at the parking position;

[0063] E. Repeat step D to gradually move the fully automatic road stud construction vehicle forward along the lane marking line and install the road studs 10 one by one at the parking position until the construction is completed.

[0064] In step C, when the sorting conveying mechanism 3 is sorting, the vibrator 35 below the storage hopper 31 drives the storage hopper 31 to vibrate and causes the safety spikes 10 inside to flow out from the discharge port 311 to the transfer track 341, and the vibrator 35 below the transfer track 341 drives the transfer track 341 to vibrate and causes the safety spikes 10 inside the transfer track 341 to move toward one end of the material sorting track 32. When the safety spikes 10 inside the transfer track 341 are piled up and down, when passing through the sweeping device 342, the sweeping device 342 sweeps the safety spikes 10 piled up on the upper layer back, and the lower layer safety spikes 10 below the sweeping device 342 flow to the material sorting track 3 after passing through the through port 343. 2, the vibrator 35 below the material sorting track 32 drives the material sorting track 32 to vibrate and causes the safety spikes 10 in the material sorting track 32 to move toward one end of the screening port 327 in a vibrating manner. The nail rods 1B of some of the safety spikes 10 that fall into the material sorting track 32 directly fall into the nail rod grooves 323. When some of the safety spikes 10 vibrate forward on the inclined inclined bottom plate 321, they slide down along the inclined bottom plate 321 under their own gravity and cause the nail rods 1B resting on the inclined bottom plate 321 to fall into the nail rod grooves 323, thereby achieving the initial material sorting. After the initial material sorting, the safety spikes 10 whose nail rods 1B have not fallen into the nail rod grooves 323 continue to vibrate forward. When the nail rods 1B rest on the inclined bottom plate 321 on one side of the nail rod grooves 323, the nail rods 1B of the safety spikes 10 are directly moved into the nail rod grooves 323. 21, and the indicator cap 1A is placed on the inclined bottom plate 321 on the other side of the nail rod groove 323, because the safety road spike 10 is vibrating forward on the material sorting track 32, when passing through the drop rod groove 324, the nail rod 1B falls from the inclined bottom plate 321 into the drop rod groove 324, and slides out of the drop rod groove 324 into the nail rod groove 323 under the guidance of the guide angle 325, so that the indicator cap 1A is hung on the inclined bottom plate 321 and slides forward, realizing secondary material sorting; these safety road spikes 10 with the nail rod 1B falling into the nail rod groove 323 and the indicator cap 1A hanging on the inclined bottom plate 321 pass through the screening port 327 and flow through the guide track 328, and the inclined safety road spikes 10 are moved by the guide track 328. After being corrected, they are input into the conveyor belt, and the conveyor belt carries the safety spikes 10 to move and sort them. The sensor 335 detects the reflective surface 1C of the safety spike 10 passing through its position. When it is detected that the position of the reflective surface 1C is wrong, the safety spike 10 is rotated by a certain angle through the rotating device 336 to make the reflective surface 1C face the set position; when the safety spike 10 is in an inverted state with the nail rod 1B facing upward on the inclined bottom plate 321, it is blocked by the baffle 326 when it moves to the baffle 326 and slides out from the slide outlet 329 during the vibration of the material sorting track 32, and is caught by the return device 36 and returned to the storage hopper 31 or the transfer device 34 to flow back to the material sorting track 32 for sorting.

[0065] The construction method of the safety road spike is simple in process, can automatically obtain the installation position of the safety road spike 10, automatically drill holes, automatically insert the safety road spike 10 into the drilled holes, and automatically hammer the safety road spike 10 to nail it firmly on the road surface. After installing one safety road spike 10, the trajectory of the lane indicator line is detected by camera shooting, and then the control system controls the vehicle body 1 to automatically drive along the lane indicator line to move to the next construction position to install the safety road spike, and continuously drives and moves the fully automatic safety road spike construction vehicle forward along the lane indicator line to carry out construction, thereby completing the installation of the safety road spikes 10 one by one, with high construction efficiency and short construction period, saving a lot of manpower and material resources, and the moving distance is stable so that the installation distance between the safety road spikes 10 is stable.
