Description

Technical Field

[0001] The present invention relates to the technical field of road maintenance equipment, and in particular to an integrated preparation device for a severe cold-type low-density road crack filling sealant. Background Art

[0002] In my country's highway construction system, strong-base, thin-surface, semi-rigid asphalt pavement has become a core paving method for highways of all grades due to its high adaptability to local pavement structures. However, due to the coupled effects of temperature gradients and vehicle loads, this type of pavement frequently develops transverse and longitudinal cracks early on. If crack filling is not promptly implemented, long-term rainwater infiltration and freeze-thaw cycles will exacerbate the deterioration of the pavement structure, leading to a sharp decline in performance and a surge in maintenance costs.

[0003] In the current crack treatment technology system, hot-dip caulking glue occupies a dominant position due to its performance and stability advantages. However, traditional products have inherent defects such as high density and insufficient low-temperature adaptability. Especially in extremely cold regions, due to the significant decrease in the flexibility and adhesion of the rubber compound, problems such as incomplete filling and short service life are often encountered. From the perspective of the preparation process, the optimization of caulking glue performance is highly dependent on the accuracy of raw material ratios, heating process control and uniform mixing, the precise integration of base asphalt and blending oil, the efficient dispersion of SBS modifiers and stabilizers, and the uniform coating of rubber powder. All of these place strict demands on the equipment's metering accuracy, temperature control capabilities, and shear mixing efficiency.

[0004] However, existing preparation equipment generally has two major technical shortcomings: First, the ratio adjustment mechanism is rigid and difficult to adapt to the dynamic metering and flexible dosing of different formulation systems, which can easily lead to modifier agglomeration or component segregation; Secondly, the heating system and the mixing device are independent of each other, and the rubber preparation and construction links are separated, which not only increases the risk of performance loss during transportation, but also makes it impossible to adjust the process parameters in real time according to the on-site working conditions, seriously restricting the timeliness and reliability of grouting construction in cold areas. Summary of the Invention

[0005] The purpose of the present invention is to provide an integrated preparation device for cold-resistant low-density road caulking sealant to solve the shortcomings of the prior art that the maintenance equipment is inconvenient to mix and cannot be heated.

One end of the push rod away from the propulsion plate is fixedly connected to a moving disk. The moving disk is placed in a grip tube. The periphery of the moving disk is slidably connected to the inner wall of the grip tube. A tilting disk is provided on the side of the moving disk away from the push rods. A positioning rod is provided between the moving disk and the tilting disk. A motor is provided on the side of the tilting disk away from the moving disk.

[0007] Preferably, a handle is fixedly connected to one side of the grip tube.

[0008] Preferably, the plurality of proportioning cylinders are evenly distributed around the axis of the grip cylinder, and the plurality of proportioning cylinders are fixedly connected to each other.

[0009] Preferably, a solenoid valve is fixedly connected to the side of the proportioning cylinder away from the axis of the grip cylinder, and a feed window is provided on the side of the proportioning cylinder close to the mixing assembly, and a solenoid valve is also installed in the feed window.

[0010] Preferably, a fixed ring groove is formed around the propulsion plate, a sealing ring is sleeved in the fixed ring groove, and the outer ring wall of the sealing ring is in contact with the inner wall of the propulsion plate.

[0011] Preferably, a guide seat is fixedly connected to one side of the moving disk, a guide groove is provided on the inner wall of the grip tube, and the guide seat is slidably connected to the wall of the guide groove.

[0012] Preferably, one end of the positioning rod is fixedly connected to the moving disk, the other end of the positioning rod is fixedly connected to the moving ball, and a sliding ring groove is provided on the surface of the inclined disk.

[0013] Preferably, the motion ball is placed in a sliding ring groove, the motion ball is slidably connected to the inner wall of the sliding ring groove, and a limit window is provided on the surface of the inclined plate.

[0014] Preferably, the output end of the motor is fixedly connected to a driving roller, the end of the driving roller away from the motor is fixedly connected to the tilting plate, the surface of the motor is sleeved with a fixing seat, and the end of the fixing seat away from the motor is fixedly connected to the inner wall of the grip tube.

[0015] Preferably, the mixing barrel is fixedly connected to an assembly ring at one end close to the storage barrel, and the proportioning barrel is fixedly connected to a connecting ring at one end close to the mixing assembly. The outer ring wall of the connecting ring and the inner ring wall of the assembly ring are provided with matching threads, and the connecting ring is fixed to the assembly ring with threads.

[0016] Beneficial effects: This invention provides an integrated preparation device for cold-weather, low-density road caulking sealant. With a handle as its core architecture, it integrates a handle, proportioning, drive, and mixing components, creating an integrated functional closed loop from material proportioning to finished product output. A handle on one side of the handle provides operational support, while a built-in drive assembly serves as the power source. A proportioning assembly on one end is responsible for material storage and precise proportioning, while a mixing assembly on the other end heats and evenly mixes the materials. Each module is tightly connected through mechanical structure and control logic.

[0017] The proportioning component is centered around a ring-shaped storage barrel, with multiple proportioning barrels evenly distributed around the axis of the grip barrel. The dual solenoid valves on the outer wall and the feed window form a two-way control node for material injection and pushing, ensuring independent storage and directional flow of materials. The push plate fits against the barrel wall through a sealing ring, and uses the displacement to accurately control the push amount of single-component materials. Differentiated proportions can be preset according to severe cold environments. The drive component rotates the tilting plate through an electric motor, converting the rotational power into linear reciprocating motion of the push plate. The guide seat, guide groove, and limit window cooperate to achieve synchronous and quantitative pushing of multiple push plates, avoiding segregation problems caused by asynchronous delivery of multi-component materials. The mixing component and the proportioning component are detachably connected, and the electric heating wires in the barrel wall constitute an embedded heating system, which provides real-time heating and insulation in severe cold weather to promote full fusion of materials. The mixed rubber material is directly output to the construction interface through the injection head, reducing performance loss during storage and transportation.

[0018] The equipment achieves dynamic adaptation of the formula through an annular proportioning cylinder and double solenoid valves, replacing complex electronic control systems with simple mechanical transmission to improve field construction stability; the integrated design of the heating wire and mixing cylinder breaks the separation between the heating and mixing links, improves the fluidity of the adhesive and the timeliness of construction, and provides a systematic solution to the problems of traditional hot-filled joint adhesives in low-temperature areas such as incomplete filling and short service life.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] The present invention provides a technical solution: Reference Figures 1 to 10 As shown, an integrated preparation device for cold-resistant low-density road caulking sealant includes a grip tube 1, a handle 101 is fixedly connected to one side of the grip tube 1, a proportioning component 2 is fixedly connected to one end of the grip tube 1, a driving component 3 is built into the grip tube 1, and a mixing component 4 is provided at the end of the proportioning component 2 away from the grip tube 1; the equipment solves the technical shortcomings of traditional preparation equipment through the coordinated work of various components.

[0024] The proportioning component 2 includes a storage barrel 201, one end of which is fixedly connected to the grip barrel 1, and the storage barrel 201 includes a plurality of proportioning barrels 202, which are evenly distributed around the axis of the grip barrel 1 and fixedly connected to each other. The plurality of proportioning barrels 202 are distributed around the grip barrel 1 to form the storage barrel 201, and a solenoid valve 203 is fixedly connected to the side of the proportioning barrel 202 away from the axis of the grip barrel 1. A feeding window 208 is provided on the side of the proportioning barrel 202 close to the mixing component 4. 8 is also equipped with a solenoid valve 203, and a push plate 205 is built into the proportioning cylinder 202. The push plate 205 is surrounded by a fixed ring groove 206, and a sealing ring 207 is sleeved in the fixed ring groove 206. The outer ring wall of the sealing ring 207 is in contact with the inner wall of the push plate 205. The proportioning component 2 of the equipment uses the storage cylinder 201 as the core carrier, which is composed of a plurality of proportioning cylinders 202 evenly distributed around the axis of the grip cylinder 1 and fixedly connected to each other. This annular distribution structure provides a physical basis for the independent storage and precise proportioning of different materials. Each mixing barrel 202 is equipped with a solenoid valve 203 on its outer wall, away from the axis of the grip barrel 1, and on the feed window 208 near the mixing assembly 4. The outer wall solenoid valve 203 controls the injection of the corresponding proportion of material. During the injection process, the solenoid valve 203 in the feed window 208 remains closed to prevent material leakage or mixing disturbance. When the material needs to be pushed toward the mixing assembly 4, the outer wall solenoid valve 203 closes and the feed window 208 solenoid valve 203 opens, ensuring that the material flows along the predetermined path. The push plate 205 inside the mixing barrel 202 is surrounded by a fixed annular groove 206 and is fitted with a sealing ring 207. The outer ring wall of the sealing ring 207 is in close contact with the inner wall of the mixing barrel 202. This design not only ensures the sealing of the push plate 205 as it slides within the mixing barrel 202, preventing material leakage during the push process, but also allows the movement of the push plate 205 to precisely control the amount of material pushed. Operators can inject different types and amounts of potting glue proportioning materials into each proportioning cylinder 202 according to different environmental requirements in severe cold areas, laying the foundation for subsequent precise mixing.

[0025] At the same time, a plurality of push rods 301 are provided in the driving assembly 3, and the plurality of push rods 301 are fixedly connected to the plurality of propulsion plates 205 respectively. The end of the push rod 301 away from the propulsion plate 205 is fixedly connected to a moving disk 302, and the moving disk 302 is placed in the grip tube 1. The moving disk 302 is slidably connected to the inner wall of the grip tube 1 on all sides. One side of the moving disk 302 is fixedly connected to a guide seat 303, and a guide groove 304 is provided on the inner wall of the grip tube 1. The guide seat 303 is slidably connected to the groove wall of the guide groove 304. A tilting disk 307 is provided on the side of the moving disk 302 away from the push rod 301, and a positioning rod 305 is provided between the moving disk 302 and the tilting disk 307. One end of the positioning rod 305 is fixedly connected to the moving disk 302, and the other end of the positioning rod 305 is fixedly connected to the moving ball 306. A sliding ring groove 308 is provided on the surface of the 07 disk, and the motion ball 306 is placed in the sliding ring groove 308. The motion ball 306 is slidably connected to the inner wall of the sliding ring groove 308. A limit window 309 is provided on the surface of the inclined disk 307. A motor 310 is provided on the side of the inclined disk 307 away from the motion disk 302. The output end of the motor 310 is fixedly connected to a driving roller 311, and the end of the driving roller 311 away from the motor 310 is fixedly connected to the inclined disk 307. A fixed seat 312 is fixedly sleeved on the surface of the motor 310, and the end of the fixed seat 312 away from the motor 310 is fixedly connected to the inner wall of the grip 1. The drive assembly 3 serves as the power core of the equipment, and converts the rotational motion of the motor 310 into a linear reciprocating motion of the propulsion plate 205 through a series of precisely matched components. Multiple push rods 301 are fixedly connected to the propulsion plate 205 at one end and to the motion disk 302 at the other end. The motion disk 302 is positioned within the grip tube 1 and is slidably connected to the inner wall of the grip tube 1 on all sides. A guide seat 303 on one side of the motion disk 302 engages a guide groove 304 on the inner wall of the grip tube 1, ensuring that the motion disk 302 slides smoothly in a fixed direction during movement, preventing deviation or shaking. A tilting disk 307 is located on the side of the motion disk 302 away from the push rods 301. The two are connected by a positioning rod 305. One end of the positioning rod 305 is fixed to the motion disk 302, and the other end of the motion ball 306 is positioned within a sliding ring groove 308 on the surface of the tilting disk 307, where it slides against the groove wall. When the motor 310 rotates the tilted disk 307 via the drive roller 311, the position of the moving ball 306 within the sliding ring groove 308 changes as the tilted disk 307 rotates, causing the moving disk 302 to reciprocate toward or away from the tilted disk 307. This motion is transmitted to the push plate 205 via the push rod 301, causing the push plate 205 to perform reciprocating linear motion within the proportioning barrel 202, pushing and resetting the proportioned materials. The stop window 309 on the surface of the tilted disk 307, in conjunction with related structures, further ensures the stability and accuracy of the movement, ensuring that multiple push plates 205 can move synchronously and precisely, thereby achieving the quantitative delivery of materials with different proportions.

[0026] Furthermore, a mixing barrel 401 is provided in the mixing component 4, and the end of the mixing barrel 401 away from the grip barrel 1 is fixedly connected to the filling head 402, the end of the mixing barrel 401 close to the storage barrel 201 is fixedly connected to the assembly ring 403, and the end of the proportioning barrel 202 close to the mixing component 4 is fixedly connected to the connecting ring 204, the outer ring wall of the connecting ring 204 and the inner ring wall of the assembly ring 403 are provided with matching threads, the connecting ring 204 and the assembly ring 403 are threadedly fixed, and an installation chamber 404 is provided inside the barrel wall of the mixing barrel 401, and a heating wire 405 is installed inside the installation chamber 404. The mixing barrel 401 of the mixing component 4 is fixed to the proportioning component 2 by the threaded connection of the connecting ring 204 and the assembly ring 403. This detachable connection method facilitates the installation, debugging and maintenance of the equipment. The end of the mixing drum 401 closest to the grip 1 docks with the feed window 208 of the proportioning assembly 2. When the push plate 205 pushes the proportioned material into the mixing drum 401 through the open solenoid valve 203 of the feed window 208, the heating wire 405 in the chamber 404 installed inside the wall of the mixing drum 401 begins to operate, heating the material entering the mixing drum 401. During construction in extremely cold regions, low temperatures can easily cause the rubber compound to cool and solidify. The heating function of the heating wire 405 effectively maintains the fluidity of the rubber compound, preventing uneven mixing or performance degradation caused by excessively low temperatures. After being heated in the mixing drum 401, the materials of different proportions are uniformly mixed through subsequent swinging and rotation, ensuring precise fusion of the base asphalt and the blending oil, efficient dispersion of the SBS modifier, and uniform coating of the rubber powder. After mixing is completed, the material is output through the pouring head 402 fixedly connected to the other end of the mixing barrel 401 for pouring into the cracks in the road. The entire process is completed in an integrated manner inside the equipment, avoiding the separation of the rubber preparation and construction links in traditional equipment.

[0027] In terms of ratio adjustment, multiple independent proportioning barrels 202, combined with dual solenoid valve 203 control and a precise push plate 205 push mechanism, can flexibly adjust the dosage of each component material according to the requirements of different formulation systems, achieving dynamic metering and flexible delivery, effectively avoiding problems such as modifier agglomeration or component segregation, and fundamentally improving the preparation quality of the caulking adhesive. In terms of heating and mixing processes, the electric heating wire 405 is directly integrated into the wall of the mixing barrel 401, tightly integrating the heating system with the mixing device. The preparation and construction of the adhesive are no longer separated, and process parameters such as the heating temperature can be adjusted in real time according to the actual working conditions on site. This not only reduces the risk of performance loss due to temperature changes during transportation, but also greatly improves the timeliness and reliability of caulking construction in cold regions. In addition, the integrated design of the equipment makes the overall structure compact and easy to operate. The ingenious design of the motor 310 driving the tilting plate 307 to drive the synchronous movement of multiple push plates 205 achieves precise and synchronous pushing of multi-component materials, improving production efficiency. The optimization of detailed structures such as the sealing ring 207, the guide seat 303 and the guide groove 304 further ensures the stability and sealing of the equipment operation, provides a strong guarantee for long-term reliable operation in severe cold environments, and lays a solid foundation for solving the problems of incomplete filling and short service life of traditional hot-filled joint glue in severe cold areas from the preparation stage.

[0028] Working principle: The device is based on a grip tube 1, with a handle 101 on one side for easy operation. One end is connected to a proportioning component 2, with a driving component 3 integrated inside. The other end of the proportioning component 2 is connected to a mixing component 4 to form an integrated working system.

[0029] The proportioning assembly 2 is centered around a storage barrel 201. It comprises a ring-shaped structure of multiple proportioning barrels 202 evenly distributed and fixed around the axis of the grip barrel 1, providing a physical foundation for the independent storage and precise proportioning of different materials. Each proportioning barrel 202 is equipped with a solenoid valve 203 on its outer wall and at the feed window 208. The outer solenoid valve 203 controls material injection. When a specific component needs to be added to the proportioning barrel 202, the operator opens the outer solenoid valve 203, allowing the material to enter the barrel under external pressure or gravity. At this time, the solenoid valve 203 in the feed window 208 remains closed, preventing material leakage from the mixing assembly 4 or premature mixing of materials in different barrels. When material injection is complete and needs to be pushed toward the mixing assembly 4, the outer solenoid valve 203 closes, cutting off the feed path, and the solenoid valve 203 in the feed window 208 opens, ensuring that material can only flow through the feed window 208 to the mixing barrel 401. Inside the mixing barrel 202, a push plate 205 is surrounded by a fixed annular groove 206 and fitted with a sealing ring 207. The outer wall of the sealing ring 207 fits tightly against the inner wall of the barrel. This design ensures a tight seal as the push plate 205 slides within the barrel, preventing leakage or cross-flow of materials with other components during the pushing process. Furthermore, by controlling the travel of the push plate 205, the volume of the pushed material can be precisely measured, ensuring that each component enters the mixing stage in the preset proportions. Operators can inject materials such as base asphalt, blending oil, rubber powder, SBS modifier, and stabilizer into each mixing barrel 202 based on environmental parameters such as temperature differences and humidity in cold regions. By adjusting the travel of the push plate 205, the amount of each material added can be controlled, laying the foundation for precise proportioning in subsequent mixing steps.

[0030] The drive assembly 3, serving as the power source, converts the rotational motion of the motor 310 into linear reciprocating motion of the propulsion plate 205 through a precise mechanical structure. Multiple push rods 301 are fixedly connected to the propulsion plate 205 at one end and to the motion disk 302 at the other. The outer periphery of the motion disk 302 slides against the inner wall of the grip tube 1, with a guide seat 303 on one side embedded in a guide groove 304 on the inner wall of the grip tube 1. This guide structure acts like a track, ensuring that the motion disk 302 always slides smoothly along the axial direction during its reciprocating motion, preventing uneven force on the push rods 301 or jamming of the propulsion plate 205 due to offset. A tilting plate 307 is located on the side of the motion disk 302 away from the push rods 301. The two are connected by a positioning rod 305: one end of the positioning rod 305 is fixed to the center of the motion disk 302, and the other end of the motion ball 306 is placed in a sliding ring groove 308 on the surface of the tilting plate 307. When the motor 310 rotates the tilting disk 307 via the drive roller 311, the movement trajectory of the moving ball 306 within the annular groove changes as the tilting disk 307 rotates, due to the fixed inclination angle between the disk surface and the axial direction. When the tilting disk 307 is at its highest point, the moving ball 306 pushes the positioning rod 305, causing the moving disk 302 to move backward. When the lower point is at its lowest point, the moving disk 302 moves forward under the action of the reset force, thus forming a periodic reciprocating motion. This motion is synchronously transmitted to the push plate 205 in each proportioning barrel 202 via the push rod 301, causing the push plate 205 to move in a uniform linear motion within the barrel, achieving quantitative material delivery and reset. The limit window 309 on the surface of the tilting disk 307 cooperates with the limit structure within the handle barrel 1 to further constrain the positional accuracy of the tilting disk 307 during rotation, ensuring the synchronous movement of multiple push plates 205 and avoiding proportioning errors caused by asynchronous movement.

[0031] The mixing drum 401 of the mixing assembly 4 is fixed to the proportioning assembly 2 through a threaded connection between the connecting ring 204 and the assembly ring 403. This detachable design facilitates disassembly and cleaning during equipment maintenance, preventing material residue from affecting the subsequent proportioning accuracy. The installation chamber 404 in the wall of the mixing drum 401 is arranged around the drum body with a heating wire 405. When the propulsion plate 205 pushes the proportioned material into the mixing drum 401 through the open feed window 208 electromagnetic valve 203, the heating wire 405 immediately starts to heat up. The heat generated is evenly transferred to the material in the drum, maintaining the fluidity of the rubber compound in a severe cold environment. Specifically, the heating wire 405 is made of a high-temperature resistant alloy material, and the heating power can be adjusted in real time according to the preparation process requirements and the on-site temperature through the temperature control system. After the materials of different proportions are heated in the mixing drum 401, the servo motor 406 inside the mixing drum 401 will drive the stirring blades 407 to drive the materials to move. Under the action of centrifugal force, the material hits the cavity wall and forms a vortex. At the same time, it is sheared by the blades and ground at the bottom, allowing the base asphalt and the blending oil to fully blend, the SBS modifier to form a network structure, and the stabilizer and rubber powder to be evenly coated. The device maintains the portability of the grouting operation. The mixed rubber is output through the grouting head 402. The front end of the grouting head 402 is designed with a conical opening, which can adapt to road cracks of different widths. It ensures that the rubber penetrates deep into the cracks under pressure and forms a tight filling. The entire preparation process, from material proportioning, heating to mixing and grouting, is integrated into the equipment. This avoids the problem of the traditional process where the rubber needs to be boiled in advance and the temperature loss after transportation to the site, significantly improving the construction efficiency and grouting quality in cold areas.
