Description

Technical Field

[0001] The present invention relates to the technical field of road construction leveling equipment, and particularly to a road paving and leveling device with a traveling direction offset function for road construction. Background Technique

[0002] During the process of road construction, it is often necessary to use concrete to harden and reinforce the road construction. The road paving and leveling device is a mobile machine used to spread, level, and compact the concrete mixed slurry. When using this kind of equipment, manual control operations are often required. The number and types of road paving and leveling devices on the market are extremely diverse. When operating on a relatively narrow road surface, a hand-held paving and leveling device with a shorter length is often used for leveling. Therefore, it is also necessary to manually drive the hand-held paving and leveling device to perform turning and offset operations.

[0003] The common road paving and leveling device is a very common device in the process of road construction. However, when operating this road paving and leveling device, it is impossible to adjust the leveling operation according to the actual construction section. Therefore, we propose a road paving and leveling device with a traveling direction offset function for road construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a road paving and leveling device with a traveling direction offset function for road construction, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A road paving and leveling device with a traveling direction offset function for road construction, including a machine base, a vibration motor, and a handrail. A connecting seat is arranged below one end of the machine base, a vibration motor is installed in the middle above the machine base, and a handrail is arranged outside the vibration motor. Sleeves are connected to both sides of the handrail, a pull plate is inserted into the sleeve, and the two pull plates are connected by a support plate. A tooth is arranged below the side of the pull plate away from the handrail;

[0006] A bracket is fixed to one side of the handrail, an adjusting gear is connected to one end of the bracket, a winding shaft is arranged on the side of the adjusting gear away from the bracket, and a traction rope is connected to the outside of the winding shaft;

[0007] A rotating seat is connected to the edge of one side of the machine base, the rotating seat is connected to a scraper, a connecting ring is arranged above the scraper, a spring is connected between the lower edge of the machine base and the scraper, and a tooth bar is fixed below the top of the handrail.

[0008] Preferably, the top of the pull plate and the top of the handrail are parallel to each other, and the pull plate and the sleeve are in an inserted connection. By inserting the pull plate into the sleeve, it can be ensured that the pull plate will not shift during movement.

[0009] Preferably, the teeth under the pull plate are distributed in a sawtooth shape, and the teeth are meshed with the adjusting gear. By meshing the teeth with the adjusting gear, it is convenient to drive the adjusting gear to rotate by sliding the pull plate up and down.

[0010] Preferably, the axis line of the adjusting gear coincides with the axis line of the winding shaft. The bottom end of the towing rope is docked with the connecting ring. By winding the towing rope around the winding shaft, the towing rope drives the scraping plate to rotate around the rotating seat through the connecting ring, so as to conveniently drive the scraping plate to rotate and open or contract.

[0011] Preferably, the scraping plate is in an arc structure, and the scraping plate and the rotating seat form a rotating structure through a spring. The clamping strip is in an "L" shape. When the top end of the pull plate is clamped with the "L"-shaped clamping strip, the scraping plate can be rotated to the limit position, so as to ensure that the scraping plate does not contact the ground.

[0012] Preferably, a transmission rod is connected between one end of the machine base and the connecting seat, and a roller is installed on the outer side of the transmission rod. The transmission rod penetrates through the outer side of one end of the connecting seat and is provided with a driving gear, and one end of the transmission rod extending out of the connecting seat is connected with a pulley. By driving the roller to rotate through the transmission rod, it is convenient for the roller to level the concrete road surface.

[0013] Preferably, a speed reducer is arranged above the machine base away from the connecting seat, and the output end of the speed reducer and the pulley are connected by a transmission belt, and a driving motor is arranged above the speed reducer. By arranging the driving motor above the speed reducer, it is convenient for the speed reducer and the driving motor to perform a speed reduction operation on the operation of the device.

[0014] Preferably, a driven gear is connected above the driving gear inside the connecting seat, and one end of the driven gear is docked with one end of the connecting rod. The outer side of the connecting rod is equiangularly installed with brush strips, and the connecting rod and the transmission rod are parallel to each other. The driving gear and the driven gear inside the connecting seat are meshed and driven, so that the brush strips on the outer side of the connecting rod driven by the driven gear can automatically clean and scrape the residual concrete slurry on the surface of the roller.

[0015] Preferably, a limiting seat is fixed at one end of the machine base away from the speed reducer, and an adjusting screw rod penetrates through the upper end of the limiting seat. The bottom end of the adjusting screw rod is connected with a movable sleeve. By rotating the adjusting screw rod to rotate threadedly on one side of the limiting seat, the adjusting screw rod can drive the cross beam to move up and down along the limiting seat.

[0016] Preferably, the bottom of the movable sleeve is fixed with a cross beam, and auxiliary wheels are arranged at both ends of the cross beam. The cross beam and the adjusting screw rod are perpendicular to each other. The adjusting screw rod and the limiting seat are in threaded connection, which is convenient to drive the auxiliary wheels at both ends of the cross beam to press on the concrete road surface, so that one end of the roller away from the connecting seat is lifted by a certain height.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The road paving and leveling device with a function of offsetting the traveling direction for road construction can adjust the scraper to level the concrete slurry on the ground by pushing the handrail at an inclined angle, ensuring that the device can perform a smooth leveling treatment on the concrete road surface. By driving the brush strip outside the connecting rod to rotate through the driven gear, the residual concrete slurry on the surface of the roller can be automatically cleaned and scraped off. By raising one end of the device with two auxiliary wheels, it is convenient for the device to have a function of assisting in turning and offsetting in the traveling direction.

[0018] 1. For the road paving and leveling device with a function of offsetting the traveling direction for road construction, by pulling the pull plate upward along the sleeve, the teeth below the pull plate are engaged with the adjusting gear for transmission, so that the winding shaft on one side of the adjusting gear winds and reels the traction rope. The traction rope drives the scraper to rotate around the rotating seat through the connecting ring, so that the scraper pulls the spring to become longer, facilitating the adjustment of the contact distance between the scraper and the ground as needed. When the concrete accumulates too much, the scraper can be adjusted to level the concrete slurry on the ground by pushing the handrail at an inclined angle, thereby ensuring that the device has the function of performing a smooth leveling treatment on the concrete road surface.

[0019] 2. For the road paving and leveling device with a function of offsetting the traveling direction for road construction, the transmission rod drives the roller to pave and level the concrete road surface. By pushing the handrail, the device moves forward smoothly. During the rotation of the transmission rod, the driving gear and the driven gear inside the connecting seat are engaged for transmission, so that the driven gear drives the brush strip outside the connecting rod to rotate, facilitating the automatic cleaning and scraping of the residual concrete slurry on the surface of the roller by the rotating brush strip, thereby ensuring that the device has the function of automatic cleaning.

[0020] 3. For the road paving and leveling device with a function of offsetting the traveling direction for road construction, the adjusting screw rotates threadedly on one side of the limit seat. Through the rotational connection between the adjusting screw and the movable sleeve, the adjusting screw moves downward along the limit seat, thereby driving the auxiliary wheels at both ends of the cross beam to press on the concrete road surface, raising one end of the roller far away from the connecting seat by a certain height, and raising one end of the device with two auxiliary wheels, so as to facilitate the device to have a function of assisting in turning and offsetting in the traveling direction.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1-8, the present invention provides a technical solution: a road paving and leveling device with a function of deviating the traveling direction for road construction, including a machine base 1, a vibration motor 3 and a handrail 4. A connecting seat 2 is arranged below one end of the machine base 1, a vibration motor 3 is installed in the middle above the machine base 1, and a handrail 4 is arranged outside the vibration motor 3. Sleeves 5 are connected to both sides of the handrail 4, a pull plate 6 is inserted into the sleeve 5, and the two pull plates 6 are connected by a support plate 7. Below the side of the pull plate 6 away from the handrail 4, there is a tooth 8. A bracket 9 is fixed on one side of the handrail 4, one end of the bracket 9 is connected to an adjusting gear 10, and a winding shaft 11 is arranged on the side of the adjusting gear 10 away from the bracket 9. A traction rope 12 is connected to the outside of the winding shaft 11. A rotating seat 13 is connected to the edge of one side of the machine base 1, the rotating seat 13 is connected to a scraper 14, and a connecting ring 15 is arranged above the scraper 14. A spring 16 is connected between the lower edge of the machine base 1 and the scraper 14, and a catch 17 is fixed below the top end of the handrail 4.

[0032] The top ends of the pull plates 6 and the handrail 4 are parallel to each other, and the pull plates 6 and the sleeves 5 are in an inserted connection; the teeth 8 below the pull plates 6 are distributed in a sawtooth shape, and the teeth 8 and the adjusting gear 10 are in a meshing connection; the axis of the adjusting gear 10 coincides with the axis of the winding shaft 11, and the bottom end of the traction rope 12 is docked with the connecting ring 15; the scraper 14 is in an arc structure, and the scraper 14 forms a rotating structure with the rotating seat 13 through the spring 16, and the catch 17 is in an "L" shape.

[0033] During manual operation, the arc-shaped scraper 14 on one side of the machine base 1 can scrape the road surface passed by the roller 19. By pulling the pull plate 6 upward along the sleeve 5, the teeth 8 below the pull plate 6 are engaged with the adjusting gear 10 for transmission, so that the winding shaft 11 on one side of the adjusting gear 10 winds and reels the traction rope 12, and the traction rope 12 drives the scraper 14 to rotate around the rotating seat 13 through the connecting ring 15, so that the scraper 14 pulls the spring 16 to become longer, facilitating the adjustment of the contact distance between the scraper 14 and the ground as needed. When there is too much concrete accumulation, by pushing the handrail 4 at an inclined angle, the scraper 14 can be adjusted to level the concrete slurry on the ground. When the top end of the pull plate 6 is clamped with the "L"-shaped catch 17, the scraper 14 can be rotated to the limit position, thus ensuring that the scraper 14 does not contact the ground.

[0034] A transmission rod 18 is connected between one end of the machine base 1 and the connecting seat 2, and a roller 19 is installed on the outer side of the transmission rod 18. A driving gear 20 is arranged on the outer side of one end of the transmission rod 18 penetrating into the connecting seat 2, and a pulley 21 is connected to the end of the transmission rod 18 penetrating out of the connecting seat 2. Above the machine base 1 far from the connecting seat 2, a speed reducer 22 is arranged, and the output end of the speed reducer 22 and the pulley 21 are connected by a transmission belt 23, and a driving motor 24 is arranged above the speed reducer 22. Inside the connecting seat 2, a driven gear 25 is connected above the driving gear 20, and one end of the driven gear 25 is butted against one end of a connecting rod 26. Brush strips 27 are installed on the outer side of the connecting rod 26 at equal angles, and the connecting rod 26 and the transmission rod 18 are parallel to each other.

[0035] The driving motor 24 is decelerated by the speed reducer 22, so that the speed reducer 22 drives the transmission rod 18 at one end of the pulley 21 to rotate through the transmission belt 23. Thus, the transmission rod 18 drives the roller 19 to pave and level the concrete road surface. The device is driven to move forward steadily by pushing the handrail 4. During the rotation of the transmission rod 18, the driving gear 20 and the driven gear 25 inside the connecting seat 2 are engaged and driven, so that the driven gear 25 drives the brush strips 27 on the outer side of the connecting rod 26 to rotate, which is convenient for the rotating brush strips 27 to automatically clean and scrape the residual concrete slurry on the surface of the roller 19.

[0036] A limit seat 28 is fixed at one end of the machine base 1 far from the speed reducer 22, and an adjusting screw 29 penetrates through the upper end of the limit seat 28. The bottom end of the adjusting screw 29 is connected with a movable sleeve 30. A cross beam 31 is fixed at the bottom of the movable sleeve 30, and auxiliary wheels 32 are arranged at both ends of the cross beam 31. The cross beam 31 and the adjusting screw 29 are perpendicular to each other, and the adjusting screw 29 and the limit seat 28 are in threaded connection.

[0037] During the movement of the device, the adjusting screw 29 rotates in a threaded manner on one side of the limit seat 28. Through the rotational connection between the adjusting screw 29 and the movable sleeve 30, the adjusting screw 29 moves downward along the limit seat 28, thereby driving the auxiliary wheels 32 at both ends of the cross beam 31 to press on the concrete road surface, so that one end of the roller 19 far from the connecting seat 2 is lifted by a certain height, and the two auxiliary wheels 32 lift one end of the device, so that it is convenient for the device to perform auxiliary turning and offset in the traveling direction. After the offset is completed, the adjusting screw 29 is rotated reversely to drive the auxiliary wheels 32 on the cross beam 31 to lift.

[0038] In summary, when the road paving and leveling device with the function of deviating the traveling direction for road construction is in use, place the device on the road under construction, and power on the vibration motor 3 and the drive motor 24, so that the vibration motor 3 vibrates the roller 19 on the machine base 1. At the same time, the drive motor 24 is decelerated by the reduction gearbox 22, so that the reduction gearbox 22 drives the transmission rod 18 at one end of the pulley 21 to rotate through the transmission belt 23. Thus, the transmission rod 18 drives the roller 19 to pave and level the concrete road surface. Push the handrail 4 to drive the device to move forward smoothly. During the rotation of the transmission rod 18, the driving gear 20 and the driven gear 25 are engaged to drive the brush strip 27 to rotate to remove the residual concrete slurry on the surface of the roller 19. During the movement of the device, the rotating adjustment screw 29 drives the auxiliary wheels 32 at both ends of the cross beam 31 to press on the concrete road surface, so that the two auxiliary wheels 32 raise one end of the device, and can assist in turning and deviating in the traveling direction. When the concrete accumulates too much, push the handrail 4 at an inclined angle to adjust the scraper 14 to level the concrete slurry on the ground, so as to smooth the concrete road surface. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
