A push rod is fixedly connected to the center of the side of the sliding stop head away from the return spring. One end of the push rod passes through the outside of the sliding seat and is fixedly connected to a guide post. The position of the guide post corresponds to the position of the bottom inclined surface of the guide head. The guide head can push the guide post towards the inner wall of the guide groove to push the sliding stop head away from the corresponding range of several push heads. After the marking hammer is completely dropped, the sliding stop head contacts the next push head. A gearbox is fixedly connected to the bottom of the inner wall of the transmission box. The output end of the gearbox is fixedly connected to one end of the bottom drive shaft. A drive roller is rotatably connected to the center of the bottom of the transmission box. The axle of the drive roller is fixedly connected to the input end of the gearbox. A shift adjustment end of the gearbox is fixedly connected to a shift lever. The shift lever passes through the outside of the transmission box.

[0014] This utility model has the following advantages:

[0015] 1. The edge pile positioning device for this road construction project uses a drive roller to push the transmission box forward. When the drive roller rotates, the power is transmitted to the transmission shaft through the gearbox, which in turn drives the transmission sprocket and transmission chain to deliver several push heads upward near the sliding seat. The push heads push the sliding stop head upward, thereby sliding the sliding seat upward and lifting the marking hammer. When it slides to the position of the guide head, the guide head can push the guide column against the inner wall of the guide groove to push the sliding stop head away from the corresponding range of the push heads. This causes the bottom of the sliding stop head to disengage from the support of the push heads, causing the marking hammer to fall rapidly and impact the road surface, leaving a mark on the ground. At the same time, the pushes are at equal intervals. As the pushes continue, equidistant markings are achieved.

[0016] 2. The side pile positioning device for this road construction project can change the transmission ratio through the gearbox, thereby controlling the speed at which the transmission chain is pushed upward, and thus controlling the speed at which the marking hammer is lifted, thereby achieving the adjustment of the marking spacing.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0024] like Figures 1 to 5As shown, a side pile positioning device for road construction includes a transmission box 1. A transmission shaft 10 is rotatably connected to the center of both the top and bottom of the inner wall of the transmission box 1. A transmission sprocket 11 is fixedly connected to the middle of the outer wall of each of the two transmission shafts 10. A transmission chain 12 is connected to the common outer wall of the two transmission sprockets 11. Several pushers 14 are fixedly connected to the outer wall of the links of the transmission chain 12. A guide head 13 is fixedly connected to the top of one side of the inner wall of the transmission box 1. A strip-shaped guide hole 3 is opened in the middle of one side of the transmission box 1. A sliding seat 4 is slidably connected to the inner wall of the strip-shaped guide hole 3. One side of the sliding seat 4 passes through the strip-shaped guide hole 3 and protrudes from the outer wall of the transmission box 1, and a marking hammer 5 is fixedly connected thereto. A guide groove 17 is opened at the bottom of one side of the sliding seat 4. A sliding stop 16 is slidably connected inside the guide groove 17. One end of the sliding stop 16 protrudes from the outside of the sliding seat 4 and corresponds to the position of the pushers 14. A return spring 18 is fixedly connected to one side of the sliding stop 16 and the inside of the guide groove 17. A push rod 19 is fixedly connected to the center of the side of the sliding stop 16 away from the return spring 18. One end of the push rod 19 extends through the outside of the sliding seat 4 and is fixedly connected to a guide post 20. The position of the guide post 20 corresponds to the position of the bottom inclined surface of the guide head 13. The guide head 13 can push the guide post 20 towards the inner wall of the guide groove 17 to push the sliding stop 16 away from the corresponding range of several push heads 14. After the marking hammer 5 has completely fallen, the sliding stop 16 contacts the next push head 14. A gearbox 15 is fixedly connected to the bottom of the inner wall of the transmission box 1. The output end of the gearbox 15 is fixedly connected to one end of the bottom drive shaft 10. A drive roller 2 is rotatably connected to the center of the bottom of the transmission box 1. The axle of the drive roller 2 is fixedly connected to the input end of the gearbox 15. A shift adjustment end of the gearbox 15 is fixedly connected to a shift lever 9, which extends through the outside of the transmission box 1.

[0025] As an optional technical solution of this utility model: a connecting plate 6 is fixedly connected to the center of the bottom side of the transmission box 1. A support roller 7 is rotatably connected to the end of the connecting plate 6 away from the transmission box 1. A push handle 8 is fixedly connected to the top of the end of the connecting plate 6 away from the transmission box 1. The support roller 7 facilitates balanced support and smooth pushing and moving.

[0026] As an optional technical solution of this utility model: the width of the sliding stop 16 is equal to the width of the plurality of push heads 14. When the sliding stop 16 corresponds to the push head 14, the distance between the side of the sliding stop 16 near the return spring 18 and the inner wall of the guide groove 17 is greater than twice the width of the sliding stop 16. The length of the return spring 18 after being fully compressed is less than the width of the sliding stop 16, so that the sliding stop 16 has sufficient sliding space to disengage from the position corresponding to the push head 14.

[0027] As an optional technical solution of this utility model: when the sliding stop 16 corresponds to the push head 14, the guide post 20 is in contact with the side of the inner wall of the transmission box 1 near the guide head 13. The length of the reset spring 18 after reset is greater than the distance between the side of the sliding stop 16 near the reset spring 18 and the inner wall of the guide groove 17 when the sliding stop 16 corresponds to the push head 14. Thus, after the reset spring 18 is reset, it can be accurately positioned by the guide post 20 being in contact with the side of the inner wall of the transmission box 1 near the guide head 13, so that the sliding stop 16 accurately corresponds to the push head 14.

[0028] As an optional technical solution of this utility model: a conical groove is provided on the bottom surface of the marking hammer 5, and an annular cutting edge is formed on the bottom surface of the marking hammer 5 through the conical groove. After the sliding seat 4 is completely lowered, the bottom surface of the marking hammer 5 can be lower than the bottom of the drive roller 2. The annular cutting edge can increase the local pressure during impact, thereby creating an annular mark on the road surface.

[0029] The working process of this utility model is as follows: When the user uses it...

[0030] 1) The drive roller 2 pushes the transmission box 1 forward. When the drive roller 2 rotates, the power is transmitted to the transmission shaft 10 through the gearbox 15, which in turn drives the transmission sprocket 11 and the transmission chain 12 to deliver several push heads 14 upward near the sliding seat 4.

[0031] 2) The pusher head 14 pushes the sliding stop head 16 upward, thereby sliding the sliding seat 4 upward and lifting the marking hammer 5;

[0032] 3) When the guide head 13 is slid to the position of the guide post 20, the guide head 13 can push the guide post 20 to push the sliding stop 16 away from the corresponding range of the push head 14, so that the bottom of the sliding stop 16 is separated from the support of the push head 14, so that the marking hammer 5 falls quickly, so that the marking hammer 5 impacts the road surface and leaves a mark on the ground.

[0033] In summary, this utility model uses a drive roller 2 to push the transmission box 1 forward. When the drive roller 2 rotates, the power is transmitted to the transmission shaft 10 through the gearbox 15, which in turn drives the transmission sprocket 11 and the transmission chain 12 to deliver several push heads 14 upward near the sliding seat 4. The push heads 14 push upward and push against the sliding stop head 16, thereby sliding the sliding seat 4 upward and lifting the marking hammer 5. When it slides to the position of the guide head 13, the guide head 13 can push the guide column 20 towards the inner wall of the guide groove 17 to push the sliding stop head 16 away from the corresponding range of the push heads 14, so that the bottom of the sliding stop head 16 is separated from the support of the push head 14, causing the marking hammer 5 to fall quickly and impact the road surface, leaving a mark on the ground. At the same time, the push intervals are equal. As the push continues, equidistant markings are achieved. The gearbox 15 can change the transmission ratio, thereby controlling the speed at which the transmission chain 12 is delivered upward during the push, and thus controlling the speed at which the marking hammer 5 is lifted, thereby adjusting the marking interval.
