Description

Technical Field

[0001] This utility model relates to the field of road and bridge joint filling technology, specifically to joint filling equipment for road and bridge construction. Background Technology

[0002] In road and bridge construction, joint filling is a construction process that uses specialized materials to fill and seal gaps in rigid or semi-rigid structures such as road surfaces and bridge decks (e.g., cement concrete pavements, asphalt concrete pavements, and expansion joint areas). These gaps are not construction defects, but rather "functional gaps" reserved to accommodate structural deformation, temperature changes, or material properties. The core function of joint filling is to ensure the durability of road and bridge structures and the safety of traffic by sealing and buffering.

[0003] Chinese Patent No. 202121280917.3 discloses a grouting device for road and bridge construction, belonging to the field of road and bridge construction equipment. It includes a base, with multiple rollers rotatably connected to the lower surface of the base. A grout storage mechanism is provided on the upper surface of the base. The grout storage mechanism includes a grout storage tank vertically fixed to the upper surface of the base. A grout conveying mechanism for conveying cement mortar is provided inside the base. The lower end of the grout storage tank is connected to the grout conveying mechanism. A grout injection mechanism is provided at one end of the grout conveying mechanism, and the grout injection mechanism is connected to the grout conveying mechanism.

[0004] The existing technical solution still has the following problems when used:

[0005] 1. The material is highly viscous, making it difficult to clean inside the tank;

[0006] 2. During the material extraction process, because it is impossible to accurately inject the slurry into the gaps, manual processing is required, which is very inconvenient.

[0007] Therefore, improvements are needed to address the aforementioned issues. Utility Model Content

[0011] Preferably, the stirring mechanism consists of a stirring shaft, a power mechanism, stirring blades, and a spiral blade. The stirring shaft is rotatably installed inside the storage tank. The upper end of the stirring shaft passes through the storage tank and is installed at the bottom end of the power mechanism. The bottom end of the power mechanism is installed at the upper end of the storage tank. The spiral blade is welded to the outside of the section of the stirring shaft that extends into the discharge pipe. The stirring blade is installed on the outside of the stirring shaft.

[0012] Preferably, the cleaning mechanism consists of a one-way bearing and a scraper. The one-way bearing is installed at the upper and lower ends of the outside of the stirring shaft, and the upper ends of the scraper are installed on the outside of the one-way bearing through brackets.

[0013] Preferably, the power mechanism consists of an electric motor and a transmission, with the transmission mounted on the upper side of the storage tank and the electric motor mounted on the upper side of the transmission.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. When the grouting equipment used in road and bridge construction rotates in the forward direction, the mixing shaft drives the relevant components to stably discharge the processed material to the material guiding mechanism. At the same time, the cleaning mechanism is activated to clean the residual material on the inner wall of the storage tank.

[0019] 2. The joint filling equipment used in this road and bridge construction features a one-way bearing with unidirectional transmission characteristics. It rotates synchronously with the mixing shaft only when the shaft rotates in the forward direction, and remains relatively stationary when rotating in the reverse direction. When the mixing shaft rotates in the forward direction, the one-way bearing drives the scraper connected to the bracket on the outside to rotate. The scraper adheres to the inner wall of the storage tank. With the rotation, the scraper removes the residual material adhering to the inner wall of the storage tank. The scraped material falls back into the tank to participate in subsequent discharge, which reduces material waste and avoids the long-term adhesion and hardening of residual material, which would affect the volume of the storage tank and the purity of subsequent materials. When the mixing shaft rotates in the reverse direction, the one-way bearing locks, and the scraper no longer rotates with the mixing shaft, avoiding interference between the scraper and the mixing blades during high-speed mixing, and ensuring that the mixing mechanism can focus on efficiently completing the material mixing operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a joint filling device for road and bridge construction, including a joint filling device 1; the joint filling device 1 consists of a base 7 and a material storage mechanism 8, the material storage mechanism 8 consists of a storage tank 17 and a mixing mechanism 23, the bottom end of the storage tank 17 is installed on the upper side of the base 7, a discharge pipe 28 is installed at the bottom end of the storage tank 17, a telescopic pipe 29 is slidably installed on the outside of the discharge pipe 28, the bottom end of the telescopic pipe 29 is installed on the upper side of the material guiding mechanism 18, the material guiding mechanism 18 is installed at the bottom end of the base 7, the mixing mechanism 23 is installed inside the storage tank 17, a mixing mechanism 23 is installed inside the storage tank 17 on the outside of the mixing mechanism 23, a cleaning mechanism 21 is installed inside the storage tank 17 on the outside of the mixing mechanism 23, a feed inlet 12 is installed on one side of the upper end of the storage tank 17, a moving mechanism 4 is installed at the bottom end of the base 7, and handrails 2 are installed on both sides of the upper end of the base 7, a controller 9 is installed on one side of the handrail 2, and a power supply mechanism 3 is installed on the other side of the handrail 2.

[0028] Furthermore, the material guiding mechanism 18 consists of a lifting plate 20, a telescopic rod 32, a V-shaped material guiding plate 19, and a wear-resistant rubber pad 16. The V-shaped material guiding plate 19 is installed on both sides of the bottom end of the lifting plate 20, the wear-resistant rubber pad 16 is installed at the bottom end of the V-shaped material guiding plate 19, the lifting plate 20 is installed at the bottom end of the telescopic rod 32, and the telescopic rod 32 is installed on the upper side of the base 7. When the material guiding mechanism 18 is in use, the telescopic rod 32 is activated by a switch, and the telescopic rod 32 drives the lifting plate 20 to move downward, so that the bottom end of the V-shaped material guiding plate 19 can fit against the construction surface. After the caulking material is conveyed from the telescopic tube 29 to the material guiding mechanism 18... The material first enters the open end of the V-shaped guide plate 19. Due to the V-shaped structure of the V-shaped guide plate 19, the material can be automatically gathered towards the middle of the bottom of the V by utilizing the guiding effect of its inclined slope, avoiding material diffusion and achieving centralized guidance of the material. At the same time, the wear-resistant rubber pad 16 installed at the bottom of the V-shaped guide plate 19 can reduce the friction wear between the guide plate and the construction surface, extend the service life of the components, and enhance the fit between the guide plate and the construction surface, preventing the material from leaking out from the gap between the guide plate and the construction surface, ensuring that the material is accurately filled into the gaps of the road and bridge, and improving the quality of the caulking operation.

[0029] Furthermore, the stirring mechanism 23 consists of a stirring shaft 25, a power mechanism 13, stirring blades 26, and a spiral blade 27. The stirring shaft 25 is rotatably installed inside the storage tank 17. The upper end of the stirring shaft 25 passes through the storage tank 17 and is installed at the bottom end of the power mechanism 13. The bottom end of the power mechanism 13 is installed at the upper end of the storage tank 17. The spiral blade 27 is welded to the outside of the section of the bottom end of the stirring shaft 25 that extends into the discharge pipe 28. The stirring blades 26 are installed on the outside of the stirring shaft 25. The power mechanism 13 drives the stirring shaft 25 to rotate inside the storage tank 17. The stirring blades 26 installed on the outside of the stirring shaft 25 rotate synchronously with the shaft, thus stirring the contents of the storage tank 17. The sealant is thoroughly mixed to break up any clumps and ensure uniform mixing, meeting the consistency requirements of the sealant application. Simultaneously, a spiral blade 27 is welded to the outer side of the section of the mixing shaft 25 that extends into the discharge pipe 28. When the mixing shaft 25 rotates clockwise, the spiral blade 27 generates a downward conveying force, assisting the material in the storage tank 17 to flow towards the discharge pipe 28, accelerating the material discharge speed and preventing blockages within the discharge pipe 28. When rotating counterclockwise, the spiral blade 27 flips the material upwards, providing more thorough mixing and pre-treatment of the material in the tank, preparing it for subsequent sealant application.

[0030] Furthermore, the cleaning mechanism 21 consists of a one-way bearing 24 and a scraper 22. The one-way bearing 24 is installed at both the upper and lower ends of the outer side of the stirring shaft 25. The upper ends of the scraper 22 are installed on the outer side of the one-way bearing 24 via brackets. The one-way bearing 24 has a one-way transmission characteristic, rotating synchronously with the stirring shaft 25 only when the stirring shaft 25 rotates in the forward direction, and remaining relatively stationary when rotating in the reverse direction. When the stirring shaft 25 rotates in the forward direction in the material discharge mode, the one-way bearing 24 drives the scraper 22 connected to the outer side via the brackets to rotate. The scraper 22 adheres to the inner wall of the storage tank 17, and as the material discharges, the scraper 22 rotates. During the rotation, the scraper 22 scrapes off the residual material adhering to the inner wall of the storage tank 17. The scraped material falls back into the tank to participate in subsequent discharge, which reduces material waste and prevents the residual material from sticking and hardening for a long time, affecting the volume of the storage tank 17 and the purity of the subsequent material. When the stirring shaft 25 rotates in the opposite direction to the material mixing mode, the one-way bearing 24 locks, and the scraper 22 no longer rotates with the stirring shaft 25, avoiding interference between the scraper 22 and the stirring blade 26 during high-speed mixing, ensuring that the stirring mechanism 23 can focus on efficiently completing the material mixing operation.

[0031] Furthermore, the power mechanism 13 consists of an electric motor 14 and a gearbox 15. The gearbox 15 is installed on the upper side of the storage tank 17, and the electric motor 14 is installed on the upper side of the gearbox 15. The electric motor 14 starts after obtaining electrical energy through the power supply mechanism 3 and outputs power at the initial speed. Since the speed required for material mixing and material discharge is different during the caulking operation, the gearbox 15 plays a role in speed regulation: when it is necessary to mix the material, the controller 9 sends a signal to the gearbox 15, and the gearbox 15 increases the speed output by the electric motor 14 and then transmits it to the mixing shaft 25, so that the mixing blade 26 rotates at high speed and mixes the material efficiently; when it is necessary to discharge the material, the gearbox 15 reduces the speed output by the electric motor 14, so that the mixing shaft 25 drives the spiral blade 27 to rotate slowly and stably, assisting in the uniform discharge of the material and avoiding waste caused by discharging the material too quickly or affecting the construction efficiency if it is too slow.

[0032] Furthermore, the moving mechanism 4 consists of casters 6 and moving wheels 5. Casters 6 are installed at both ends of one side of the bottom of the base 7, and moving wheels 5 are installed on both sides of the bottom of the other side of the base 7. When the operator pushes the handrail 2, the moving wheels 5 rotate under the thrust, providing the equipment with the power to move forward or backward, and can move in a straight line according to the construction path. When it is necessary to change the direction of the equipment's movement, since casters 6 have 360-degree rotation characteristics, the operator only needs to apply lateral force in the desired direction of turning, and casters 6 can rotate flexibly, driving the equipment to change the direction of travel and adapt to the different gaps in road and bridge construction.

[0033] Furthermore, a display 10 is installed on one end of the upper side of the controller 9, and control buttons 11 are installed on the other end of the upper side of the controller 9. The controller 9 serves as the control center of the equipment, responsible for receiving operation commands, monitoring the equipment status, and coordinating the operation of various components. During operation, it can display key operating parameters of the equipment in real time, such as the battery level 31, the speed of the stirring shaft 25, and the extension height of the telescopic rod 32, allowing operators to intuitively understand the working status of the equipment and promptly detect abnormalities. The control buttons 11 on the other end of the upper side include various function buttons, such as power switch, stirring start / stop button, forward / reverse switch button, telescopic rod 32 lifting button, and moving wheel 5 start / stop button. Operators send commands to the controller 9 by pressing the corresponding buttons. After receiving the commands, the controller 9 transmits electrical signals to the corresponding actuators, such as the power mechanism 13, the telescopic rod 32, and the moving mechanism 4, and the control components act according to the commands.

[0034] 9. The power supply mechanism 3 consists of a battery 31 and a charging port 30. The battery 31 is installed on the upper side of the handrail frame 2, and the charging port 30 is installed on the upper side of the battery 31. The electrical energy stored inside the battery 31 is connected to various electrical components of the equipment, such as the controller 9, the motor 14, and the drive device of the telescopic rod 32, through wires to supply power to them. Before the equipment is used, if the battery 31 is low on power, it can be charged by connecting an external power source through the charging port 30. During the charging process, the charging protection circuit inside the battery 31 can prevent overcharging, ensuring the service life and safety of the battery 31. When the equipment is running, the battery 31 supplies power to various components in real time. At the same time, the power sensor transmits the remaining power information of the battery 31 to the controller 9. The controller 9 displays the power level in real time through the display 10, reminding the operator to charge in time to avoid construction interruption due to insufficient power. In addition, the circuit design of the power supply mechanism 3 has an overload protection function. When a short circuit or overload occurs in a component of the equipment, the protection circuit automatically cuts off the power supply to prevent damage to the component and ensure the safety of the equipment and the operator.

[0035] Working Principle: When using the joint filling equipment for road and bridge construction, the joint filling material is first injected into the storage tank 17 through the feed inlet 12 at the top. The power supply mechanism 3 supplies power to the entire equipment, and the controller 9 acts as the control center to coordinate the work of each component. When joint filling is required, the controller 9 controls the stirring mechanism 23 to start, stirring the material in the storage tank 17 to prevent sedimentation and agglomeration, ensuring the uniformity of the material. After stirring, the material flows out through the discharge pipe 28 at the bottom of the storage tank 17. At the same time, the telescopic pipe 29 can be flexibly adjusted according to the construction height requirements to accurately deliver the material to the guide mechanism 18 installed at the bottom of the base 7. In addition, the moving mechanism 4 at the bottom of the base 7 facilitates the movement of the equipment on the road and bridge construction surface. During operation, the handrails 2 on both sides provide support for the operators. The controller 9 on one handrail 2 facilitates real-time operation, while the power supply mechanism 3 on the other side ensures continuous operation, enabling the equipment to move and fill gaps simultaneously. In particular, the equipment has a bidirectional operating mode: when rotating in the forward direction, the stirring shaft 25 drives the relevant components to stably discharge the processed material to the material guiding mechanism 18, and at the same time, the cleaning mechanism 21 is activated to clean the residual material on the inner wall of the storage tank 17; when rotating in the reverse direction, the stirring mechanism 23 operates independently and efficiently to fully mix the material in the tank. At this time, two people are required to assist in supporting the handrails 2 on both sides. With the help of the casters 6 and the moving wheels 5, the direction of equipment movement can be controlled more precisely to adapt to different construction path requirements.

[0036] These are the characteristics of joint filling equipment used in road and bridge construction. Any content not described in detail in this document is existing technology known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
