Description

Technical Field

[0001] The invention relates to the technical field of road construction equipment, in particular to an automatic joint processing device for road pavement paving. Background Art

[0002] With the continuous advancement of modern urbanization, the construction of road traffic infrastructure has become an important support for urban development. Whether it is a highway, a city trunk road, or a municipal pedestrian road, the demand for its paving and maintenance is increasing year by year. In these projects, joint treatment, as an important link in road paving, not only directly affects the flatness and service life of the road surface, but also puts forward strict requirements on construction quality and efficiency. The traditional joint treatment method mainly relies on manual operation, which is completed by cleaning the joints, filling the joints with joint agents, and subsequent coating protection. Although this method has certain flexibility, it is inefficient and difficult to guarantee quality. Especially in large-scale projects, manual operation is prone to errors, resulting in uneven joints, material waste, and even construction defects.

[0003] In order to make up for the shortcomings of manual processing, mechanized and automated equipment has gradually been introduced into the field of joint processing in recent years. These devices improve construction efficiency and partially reduce manual labor intensity by integrating single or partial construction links, such as joint cleaning, grouting or laminating. However, the functions of these existing equipment are mostly independent and scattered, lacking a systematic integrated design. For example, some equipment can only complete the filling of joints, while other equipment is dedicated to laminating. Manual connection is required between processes, which not only increases equipment investment and operating costs, but also prolongs the construction period. This process-splitting mode is particularly obvious in complex or emergency construction scenarios. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automated joint processing device for road pavement paving, which solves the problems of existing joint processing equipment having dispersed functions, poor adaptability, and difficulty in balancing construction efficiency and quality.

[0006] Preferably, the transmission assembly comprises a sprocket, and a plurality of the sprockets are symmetrically arranged on both sides of the outer walls of the plurality of transmission rods, and a chain is provided on the outer wall engagement sleeves of the plurality of sprockets for transmitting power to drive the coating assembly.

[0007] Preferably, the coating assembly includes a film roller, which is installed on the outer wall of one of the transmission rods, wherein the outer wall of one of the transmission rods is fixedly connected to a first gear, a load-bearing plate is fixedly connected to one side of the bottom of the frame, an auxiliary rod is rotatably connected to the inner wall of the load-bearing plate, one side of the auxiliary rod is fixedly connected to the second gear, a plurality of springs are provided on the inner wall of the auxiliary rod, and a plurality of pressure plates are slidably connected to the inner wall of the auxiliary rod.

[0008] Preferably, the cleaning assembly includes a positioning plate, which is fixedly connected to the bottom of the frame, the top of the positioning plate is rotatably connected to a plurality of fourth bevel gears, the bottom of the positioning plate is symmetrically fixedly connected to a directional plate, the outer wall of one of the transmission rods is symmetrically fixedly connected to a third bevel gear, and the bottom of the fourth bevel gear is fixedly connected to a sweeping disc.

[0009] Preferably, the first gear is meshingly connected to the second gear, and the inner wall of the load-bearing plate is rotatably connected to a plurality of stabilizing rollers.

[0010] Preferably, the fourth bevel gear is meshingly connected to the third bevel gear, and the sweeping disc is slidably connected to both sides of the bottom of the positioning plate.

[0011] Preferably, the injection head is fixedly connected to the bottom of the frame, and the inner wall of the injection head is communicated with the inner wall of the liquid transfer rod.

[0012] Preferably, a towing hook is installed on one side of the frame, and wheels are installed on both sides of the plurality of transmission rods.

[0013] Preferably, a top cover is provided on the top of the containing box via a hinge, and a flange pipe interface is provided on one side of the containing box.

[0014] Preferably, the bottom of the load-bearing plate is provided with a through groove, and the pressure plate is made of rubber material and is in contact with the ground.

[0015] Working principle: When paving the road surface and filling the joints, first connect it to the vehicle or other driving device through the towing hook, and then locate the joint position for processing.

[0016] When the frame is moved, the rotation of the wheels will synchronously drive the grouting assembly, cleaning assembly and coating assembly to work. First, one of the transmission rods will drive the third bevel gear to engage with the fourth bevel gear to drive the sweeping disc at the bottom of the positioning plate to rotate towards each other, and then the impurities in the joints will be swept off both sides by the relative rotation of the sweeping discs on both sides, and the impurities will be separated by the directional plate so that a certain coating space can be presented in the middle. Then, during the movement, as the transmission rod drives the first bevel gear to rotate, the meshing transmission will drive the rotating rod rotating on the inner wall of the containing box to rotate. During the rotation, the joint liquid is continuously stirred by the dynamic stirring blade to avoid sedimentation and stratification. In the stirring state, the joint liquid inside the containing box is in a circulating liquid state from bottom to top, thereby entering the top of the wrapping ring, and through the contact between the auger blade and the wrapping ring, the joint liquid is discharged into the inner cavity of the injection head through the communicating liquid transfer rod, and enters the joint by gravity to complete the filling.

[0017] The integral grouting assembly operates continuously through the power transmission of the transmission assembly. When the operating direction is reversed, the grouting liquid will continue to circulate in the holding box, which also reduces the use of valves.

[0018] After grouting for a certain distance, when coating is required, the film can be manually removed from the outer wall of the film roller, and then fixed to the bottom of the auxiliary rod by the stabilizing rollers on both sides. During the continuous operation of this device, the film can be placed on the top of the unsolidified joint slurry in stages through the push of the spring, and the setting of the first gear and the second gear can make the auxiliary rod and the film roller rotate relative to each other during operation, thereby achieving the effect of placing the film and coating at the same time.

[0019] The present invention provides an automatic joint processing device for road pavement paving, which has the following beneficial effects: 1. The present invention realizes fully automated processing from joint surface cleaning to joint agent filling and film covering through the coordinated use of components such as a containing box, a transmission rod, and a sprocket, reducing the efficiency loss and process disconnection problems caused by segmented operations in traditional manual multi-equipment operations, greatly improving the overall construction efficiency. At the same time, through the power linkage mechanism of the transmission rod and the chain, each module can work in coordination to ensure the continuity and consistency of the construction process.

[0020] 2. The present invention realizes synchronous covering of the film after the joint agent is filled through the film roller and spring loading design of the coating assembly. The film can fit tightly to the joint surface under the action of the auxiliary rod and the pressure plate to prevent external impurities from contaminating the unsolidified joint agent, and effectively avoid the joint agent from losing water and cracking too quickly due to wind, sunlight and other reasons.

[0021] 3. The present invention adopts a design of dynamically stirring and conveying the joint agent by stirring blades and auger blades, thereby avoiding the problem of joint agent deposition or stratification inside the containing box. At the same time, by combining the gravity of the grouting component with mechanical conveying, it ensures that the joint agent can be evenly injected into the joint area. The filling process is uninterrupted and highly dense, effectively avoiding the problem of uneven distribution of joint agent or the appearance of gaps in traditional construction.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Please refer to the attached Figure 2 -Attached Figure 3 The embodiment of the present invention provides an automated joint processing device for road pavement, including a frame 1, and a container 2 is fixedly connected to the top of the frame 1, which is used to store joint agent and provide material support for the grouting process. The top of the container 2 is connected to a top cover through a hinge, and the top cover can facilitate the filling and sealing of the joint agent, prevent impurities from entering the interior of the container 2, thereby ensuring the smooth grouting process. A flange pipe interface is provided on one side of the container 2 for connecting to an external material supply device or auxiliary equipment, so as to facilitate the replenishment and flow control of the joint agent during continuous construction.

[0026] The inner wall of the frame 1 is rotatably connected with a plurality of transmission rods 3, which serve as the core components for power transmission of the entire device. Through a mechanical transmission mechanism, the plurality of transmission rods 3 work in coordination to drive the grouting assembly and the cleaning assembly to work. Among them, a first bevel gear 5 is fixedly connected to both sides of the outer wall of a transmission rod 3, and the first bevel gear 5 is connected to the second bevel gear 6 rotatably connected to the bottom of the receiving box 2 by meshing. The meshing connection formed by the first bevel gear 5 and the second bevel gear 6 can transmit the rotational motion of the transmission rod 3 to the rotating rod 7 inside the receiving box 2, ensuring that the joint agent inside the receiving box 2 can continue to circulate dynamically during the mixing and conveying process.

[0027] The top of the rotating rod 7 is fixedly connected to the second bevel gear 6, and a plurality of stirring blades 10 are fixedly connected to one side of its outer wall. The stirring blades 10 dynamically stir the joint agent inside the receiving box 2 during the rotation of the rotating rod 7 to avoid the deposition or stratification of the joint agent in the receiving box 2, thereby maintaining the uniformity and fluidity of the joint agent. In addition, a wrapping ring 8 is installed on the inner wall of the receiving box 2, and the wrapping ring 8 is tightly attached to the outer wall of the rotating rod 7 to form a stable material conveying path. The outer wall of the rotating rod 7 is also installed with an auger blade 9, which is tightly attached to the inner wall of the wrapping ring 8 and pushes the joint agent upward along the inner wall of the wrapping ring 8 through rotation.

[0028] The liquid transfer rod 26 passes through the containing box 2, and its upper end is communicated with the wrapping ring 8, and is used to receive the joint agent transported by the auger blade 9. Through the continuous pushing action of the auger blade 9, the joint agent can enter the inner cavity of the liquid transfer rod 26, and be transported to the injection head 27 along the path of the liquid transfer rod 26. The injection head 27 is fixedly installed at the bottom of the frame 1, and its inner cavity is communicated with the inner cavity of the liquid transfer rod 26, and is used to directly inject the joint agent into the joint to be treated. Due to the gravity of the injection head 27, the joint agent can evenly fill the joint at a stable flow rate, ensuring the density and continuity of the joint treatment.

[0029] Please refer to the attached Figure 2 The transmission assembly includes a sprocket 4, and the plurality of sprockets 4 are symmetrically arranged on both sides of the outer wall of the plurality of transmission rods 3. The outer wall of the sprocket 4 is provided with a chain 11 through an engaging sleeve to realize the transmission of power. The transmission assembly transmits the rotational power of one transmission rod 3 to other transmission rods 3 through the linkage of the chain 11, so as to realize the coordinated work of various components. The tight meshing connection of the chain 11 can ensure the continuity and stability of power transmission, and effectively avoid power interruption caused by sliding or tooth jumping. In addition, the design of the transmission assembly can synchronously drive the coating assembly so that it can work with the movement during the operation of the device.

[0030] Please refer to the attached Figure 4 -Attached Figure 6 The film coating assembly includes a film roller 14, which is mounted on the outer wall of one of the transmission rods 3 and is used to store and transport the film to cover the seam area. A first gear 15 is fixedly connected to the outer wall of one of the transmission rods 3, and the first gear 15 is connected to a second gear 16 fixedly connected to one side of the auxiliary rod 17 through meshing transmission to achieve power transmission. A load-bearing plate 12 is fixedly connected to one side of the bottom of the frame 1, and the inner wall of the load-bearing plate 12 is rotatably connected to the auxiliary rod 17 to provide stable support for the placement and transmission of the film.

[0031] The inner wall of the auxiliary rod 17 is provided with a plurality of springs 19, which are used to provide elastic support and pressure adjustment to ensure that the film can evenly cover the joint area. The inner wall of the auxiliary rod 17 is slidably connected with a plurality of pressure plates 18, which are made of rubber material and can contact the ground under the push of the springs 19, providing a stable compression effect for the film, so that the film fits tightly to the surface of the unsolidified joint material. The inner wall of the load-bearing plate 12 is also rotatably connected with a plurality of stabilizing rollers 13, which are used to stabilize the tension and flatness of the film during the laying process to prevent the film from wrinkling or slipping.

[0032] The bottom of the load-bearing plate 12 is provided with a through groove, which provides space for the sliding of the pressure plate 18, so that it can flexibly adjust the height under the action of the spring 19 to adapt to different joint surface morphologies. The first gear 15 is connected with the second gear 16 by meshing, and when the transmission rod 3 rotates, the auxiliary rod 17 is driven to rotate relative to each other, so that the film roller 14 can perform the film coating operation while placing the film. Through stable mechanical transmission and elastic adjustment, the film coating component can synchronously complete the film coating of the joint during the construction process, effectively protect the unsolidified joint material, prevent pollution and cracking, and improve the construction efficiency and quality.

[0033] Please refer to the attached Figure 7 -Attached Figure 8 The cleaning assembly includes a positioning plate 28, which is fixedly connected to the bottom of the frame 1 and is used to provide a mounting base and structural support for the cleaning assembly. The top of the positioning plate 28 is rotatably connected to a plurality of fourth bevel gears 21, which are connected to a third bevel gear 20 fixedly connected to the outer wall of a transmission rod 3 through meshing transmission, thereby realizing power transmission. The meshing connection between the third bevel gear 20 and the fourth bevel gear 21 can effectively transmit the rotational power of the transmission rod 3 to the cleaning assembly, so that it can operate synchronously with other functional modules.

[0034] The bottom of the positioning plate 28 is symmetrically fixedly connected with a directional plate 22. The function of the directional plate 22 is to define the boundary of the cleaning area and guide the impurities removed during the cleaning process to both sides of the road surface to prevent the impurities from interfering with the subsequent steps of the joint treatment. The bottom of the fourth bevel gear 21 is fixedly connected with a sweeping disc 23. The sweeping disc 23 is slidably connected to both sides of the bottom of the positioning plate 28 and cleans the joint area through rotation. The sweeping disc 23 is designed to rotate in opposite directions, which can efficiently remove dust, impurities or loose materials in the joint area, providing a clean construction surface for joint treatment.

[0035] The sweeping disc 23 is slidably connected to both sides of the bottom of the positioning plate 28, so that it can be flexibly adjusted to a certain extent according to the width of the joint area or the height of the ground, ensuring the comprehensive coverage and uniformity of the cleaning effect. The meshing transmission structure of the fourth bevel gear 21 and the third bevel gear 20 is simple and reliable, and the continuous cleaning action of the sweeping disc 23 can be realized through the rotation of the transmission rod 3, avoiding manual operation and improving construction efficiency.

[0036] The cleaning component ensures the cleanliness of the joint surface by cleaning and directionally separating impurities in the joint area, providing a good foundation for grouting and covering operations, and can adapt to different construction environments and road conditions.

[0037] Please refer to the attached Figure 1 -Attached Figure 2 A traction hook 24 is installed on one side of the frame 1 for connecting with an external vehicle or other driving device to realize the movement and power transmission of the entire device. The traction hook 24 is designed to have sufficient strength and stability to withstand the traction force generated by the device during the construction process, ensuring that the device runs smoothly and safely. Through the setting of the traction hook 24, the device can adapt to a variety of traction methods, including manual traction, mechanical traction or traction of other auxiliary power equipment.

[0038] Wheels 25 are installed on both sides of the multiple transmission rods 3. The wheels 25 provide mobile support for the device, ensuring that the device can move smoothly in the construction area. The wheels 25 are arranged symmetrically and evenly distributed, which can effectively disperse the overall weight of the device and adapt to construction conditions on different ground surfaces. The wheels 25 are designed to have a large ground contact area and can adapt to a variety of complex road conditions, including flat roads, irregular ground or construction areas with large slopes, thereby ensuring the continuity and stability of construction.

[0039] Through the combined design of the traction hook 24 and the wheel 25, the device not only has good mobility, but also can convert movement into a power source for internal mechanical transmission through external traction. The rotation of the wheel 25 combined with the transmission rod 3 can synchronously drive multiple functional modules of the device (such as the cleaning component, grouting component and film covering component) to work together, further improving construction efficiency and work quality.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
