Description

Technical Field

[0001] This invention relates to the field of road engineering maintenance machinery technology, and in particular to a bridge and road maintenance and repair construction device and construction method. Background Technology

[0002] In bridge and road maintenance, crack repair is a crucial step in ensuring structural safety. Existing crack repair equipment suffers from several drawbacks. Large machines are difficult to maneuver and adapt to narrow or complex road sections, while smaller machines have limited storage capacity, requiring frequent refills. Some methods involve using transport vehicles carrying storage containers to individually supply asphalt to small crack repair machines during operation. While this improves flexibility, the residual asphalt inside the machine after repair is difficult to recycle, leading to material waste and cleaning difficulties. This not only increases maintenance costs but also impacts construction efficiency. Therefore, a more effective solution is needed to balance equipment flexibility, storage capacity, and the need for residual asphalt recycling. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as increased maintenance costs and reduced construction efficiency, by proposing a bridge and road maintenance and repair construction device and method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A bridge and road maintenance and repair construction device includes a vehicle and also includes:

[0006] A storage bin is installed on the vehicle, and a stirrer is installed inside the storage bin.

[0007] The lifting mechanism includes two fixed frames, a threaded rod, a lifting seat, and an L-shaped placement frame. The two fixed frames are fixedly installed on the side of the vehicle. The threaded rod is rotatably installed in one fixed frame, and a limit rod is fixedly installed in the other fixed frame. The lifting seat is threaded onto the threaded rod and slidably mounted on the limit rod. The top of the vertical part of the L-shaped placement frame is rotatably connected to the bottom of the lifting seat.

[0008] A seam repair machine, comprising a trolley, a storage cylinder mounted on the trolley, a cover plate hinged to the top of the trolley, a discharge pipe connected to the storage cylinder fixedly mounted on the side wall of the trolley, a sealing cap rotatably mounted on the outer wall of the discharge pipe, the sealing cap being kept normally closed by a torsion spring, and casters mounted on the bottom of the trolley.

[0009] In one possible design, a valve is installed on the outer wall of the storage tank, and a receiving tray is rotatably installed on the vehicle below the valve;

[0010] The receiving tray is used to guide asphalt from the valve to the storage cylinder.

[0011] In one possible design, the grouting machine also includes a pinch handle, which is rotatably mounted below a push handle. A steel wire connects the pinch handle and the cap. A guide frame is fixedly mounted on the outer side wall of the trolley, and a discharge rack is fixedly mounted at the end of the guide frame.

[0012] The operation involves using a handle to open the cap via a steel wire, allowing the asphalt to flow into the gap through a guide frame and a discharge frame.

[0013] In one possible design, the lifting mechanism further includes an upper fixed clamp and a lower movable clamp. The upper fixed clamp is fixedly installed on the side wall of the vertical part of the L-shaped placement rack, and the lower movable clamp is slidably installed on the side wall of the vertical part of the L-shaped placement rack. A locking rod is fixedly installed on the outer side wall of the trolley, and the locking rod is locked between the upper fixed clamp and the lower movable clamp. A fixing plate is fixedly installed on the side wall of the vertical part of the L-shaped placement rack. A limiting shaft is fixedly installed at the bottom of the lower movable clamp, and the limiting shaft slides through the fixing plate. A compression spring is sleeved on the outer wall of the limiting shaft, and the two ends of the compression spring are respectively fixed to the top of the fixing plate and the bottom of the lower movable clamp. The side wall of the lower movable clamp is machined into a bevel.

[0014] When the clamping rod contacts the inclined surface, it moves downward to move the clamping clamp. After resetting, it clamps the clamping rod to fix the seam repair machine.

[0015] In one possible design, an L-shaped inner limiting frame and an L-shaped outer limiting frame are fixedly installed on the side walls of the fixed frame, and side grooves are provided on both sides of the horizontal part of the L-shaped placement frame, the side grooves cooperating with the L-shaped outer limiting frame.

[0016] A construction method based on the bridge and road maintenance and repair construction device includes:

[0017] S1. Open the valve, and the asphalt flows through the receiving tray into the storage cylinder. Move the joint repair machine away from the L-shaped placement frame to carry out the joint repair operation.

[0018] S2. Move the joint repair machine to the joint using the push handle, operate the pinch handle to open the cover, and the asphalt flows into the joint through the guide frame and the discharge frame and is scraped smooth;

[0019] S3. When the asphalt in the storage cylinder is insufficient, push the joint repair machine back to the L-shaped placement frame, press the inclined plane with the clamping rod to make the lower moving clamp move down and then reset the clamping position, and open the valve to replenish;

[0020] S4. After the operation is completed, drive the threaded rod to lift the lifting seat, and the clamp rod enters the inner side of the L-shaped inner limit frame to fix the repair machine for stable transfer;

[0021] S5. When there is remaining material in the storage hopper, continue to lift it so that the side channel is disengaged from the L-shaped outer limit frame, and rotate the L-shaped placement frame to make the asphalt flow back into the storage hopper.

[0022] In one possible design, in step S1, the receiving tray is rotated so that its end is above the storage cylinder, and hot asphalt flows from the storage cylinder through the valve and the receiving tray into the storage cylinder.

[0023] In one possible design, in step S2, the bottom of the discharge rack is aligned with the crack, and excess asphalt is scraped off as the crack repair machine is pushed forward.

[0024] In one possible design, in step S5, the rotating L-shaped placement rack is more than 90 degrees, the opening of the storage cylinder faces the storage bucket, and the remaining asphalt flows back to the storage bucket under the action of gravity.

[0025] In one possible design, during step S3, when the storage cylinder is replenished, the L-shaped placement rack is located at the bottom.

[0026] In this application, during actual use, the worker opens the valve, and the asphalt flows through the receiving tray into the storage cylinder. Then, the crack repair machine can be moved outward to perform the crack repair operation. Subsequently, the worker moves the crack repair machine to the vicinity of the ground crack by pushing the handle, with the discharge rack facing the crack. Then, the worker holds the handle and pulls the steel wire, thereby rotating and opening the cover, allowing the asphalt to flow into the crack through the guide frame and the discharge rack. Then, while moving forward, the asphalt is scraped smooth by the bottom surface of the discharge rack.

[0027] If the asphalt in the storage cylinder is used up and repairs are still needed, push the joint repair machine onto the L-shaped placement frame, and after the clamping rod is in contact with the inclined surface, the lower moving clamp moves downward by overcoming the force of the compression spring, so that the clamping rod is locked between the upper fixed clamp and the lower moving clamp. Then the lower moving clamp is reset by the compression spring and locked. After that, the valve can be opened again for replenishment.

[0028] After the work is completed, the grout repair machine is repositioned onto the L-shaped placement frame. Then, the motor connected to the threaded rod is driven to move the grout repair machine upwards via the lifting seat. Once it moves upwards, the clamping rod will move to the inside of the L-shaped inner limit frame, preventing the grout repair machine from moving outwards and thus fixing it in place to ensure stability during transport.

[0029] When the work is completed and there is still asphalt in the storage hopper, the L-shaped placement frame and the joint filling machine will continue to move upward based on the above steps. When the side groove of the L-shaped placement frame is out of the range of the L-shaped outer limit frame, the restriction on the rotation of the L-shaped placement frame will be released, allowing the worker to push the L-shaped placement frame and the joint filling machine to rotate together. After rotating more than 90 degrees, the asphalt can flow back into the storage hopper. Due to gravity, the joint filling machine will be close to the vertical part of the L-shaped placement frame when pouring material, which can ensure a stable pouring process.

[0030] In this invention, a bridge and road maintenance and repair construction device is provided. The small crack-sealing machine is easy for operators to operate, enabling them to conveniently repair cracks in bridges and roads, thereby maintaining them and increasing their service life.

[0031] In this invention, the bridge and road maintenance and repair construction device, through a lifting mechanism, can both connect the joint repair machine to ensure stable supply operations and adjust it to different positions to achieve the effects of material transfer and return.

[0032] When the lifting mechanism is raised to the middle position, the clamping rod of the grouting machine automatically enters the inner side of the L-shaped inner limit frame on the side wall of the vehicle. The mechanical limit structure completely restricts the horizontal movement of the grouting machine, ensuring that the equipment has no risk of shaking during transportation.

[0033] In this invention, by integrating the functions of material storage, mixing, patching, and waste material recycling into the vehicle platform, operators do not need to travel back and forth to transport materials. The patching machine's replenishment, fixing, and recycling operations can all be completed quickly through the mechanical structure, thereby solving the problems of low flexibility of large devices, limited storage space of small devices, and difficulty in recycling waste materials when using a single large and small device.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] In one embodiment: Reference Figure 1-2 A construction device includes: a carrier 1, on which a storage tank 2 is bolted to a top platform. A stirrer 3 is vertically installed inside the storage tank 2. The drive motor of the stirrer 3 is fixed to the center of the top of the storage tank 2 via a bracket. The stirring blades extend to the bottom of the storage tank 2. Heating elements such as heating wires are installed within the interlayer of the storage tank 2. A discharge connector is welded to the lower part of the side wall of the storage tank 2, and a valve 7 is installed on the discharge connector. A receiving tray 8 is rotatably connected to the platform of the carrier 1, located directly below the valve 7, allowing it to be unfolded for receiving materials or folded up.

[0042] refer to Figure 4 The lifting mechanism 4 includes two symmetrically welded fixed frames 410 on the sides of the vehicle 1. A threaded rod 415 is rotatably mounted in the left fixed frame 410 via a bearing, and a limit rod is welded in the right fixed frame 410. The left end of the lifting seat 413 has an internal threaded hole that engages with the threaded rod 415, and the right end has a smooth hole that slides with the limit rod. The top of the vertical part of the L-shaped placement frame 414 is rotatably connected to the bottom of the lifting seat 413 via a bearing. A limit plate is welded to the side of the lifting seat 413 closest to the vehicle 1. This limit plate contacts the outer wall of the vertical part of the L-shaped placement frame 414 to prevent it from rotating inward toward the vehicle 1.

[0043] refer to Figure 3The grouting machine 5 includes a trolley 510 body and a corresponding storage cylinder 511. A cover plate 512 hinged to the trolley 510 cooperates with the storage cylinder 511. A discharge pipe 523 is welded to the lower part of the side wall of the storage cylinder 511. A cover 521 is rotatably connected to the outer wall of the cylinder via a pin. A torsion spring 522 is sleeved on the pin to keep the cover 521 in a normally closed state. A push handle 514 is welded to the rear of the trolley 510. A pinch handle 515 is installed below the left push handle 514 via a rotating shaft. A steel wire 516 connects the pinch handle 515 and the cover 521. Multiple casters 517 are installed at the bottom of the trolley 510. A guide frame 518 is welded to the side wall. A discharge rack 519 is welded to the end of the guide frame 518. The bottom of the discharge rack 519 is machined into a scraper plate parallel to the ground.

[0044] refer to Figure 5 The vertical sidewall of the L-shaped placement frame 414 of the lifting mechanism 4 is welded with an upper fixed clamp 416. A lower movable clamp 421 is slidably mounted on the vertical part of the L-shaped placement frame 414 via a linear bearing. A limiting shaft 419 is welded to the bottom of the lower movable clamp 421. The limiting shaft 419 slides through a fixed plate 418, which is welded to the sidewall of the L-shaped placement frame 414. A compression spring is sleeved on the outer wall of the limiting shaft 419, and both ends of the compression spring are welded to the fixed plate 418 and the lower movable clamp 421, respectively. A bevel 417 is machined on the top of the lower movable clamp 421. A locking rod 520 welded to the sidewall of the trolley 510 is inserted between the upper fixed clamp 416 and the lower movable clamp 421 to achieve connection.

[0045] This embodiment is based on a construction method using a maintenance and repair construction device.

[0046] S1. During the material replenishment stage, the operator rotates the receiving tray 8 so that its end is above the storage cylinder 511, opens the valve 7 to allow the hot asphalt in the storage tank 2 to flow into the receiving tray 8, and then into the storage cylinder 511. After that, the operator pulls the joint repair machine 5 to disengage the clamping rod 520 from the clamping of the upper fixed clamp 416 and the lower moving clamp 421.

[0047] S2. Crack repair operation: Move the crack repair machine 5 to the crack location using the push handle 514, aligning the scraper plate of the discharge rack 519 with the crack. The operator holds the pinch handle 515 with one hand, and the steel wire 516 drives the cover 521 to rotate and open against the elastic force of the torsion spring 522. Asphalt flows into the crack through the guide frame 518 and the discharge rack 519, and then the crack repair machine 5 is pushed forward, with the scraper plate scraping away excess asphalt.

[0048] S3. Mid-process replenishment: When the remaining amount of asphalt in the storage cylinder 511 is insufficient, push the joint repair machine 5 back to the L-shaped placement frame 414 so that the clamping rod 520 contacts the inclined surface 417 of the lower moving clamp 421. Continue to push the trolley 510. The clamping rod 520 squeezes the inclined surface 417, causing the lower moving clamp 421 to move down along the limiting shaft 419. After the clamping rod 520 passes the inclined surface 417, the lower moving clamp 421 resets under the action of the compression spring and clamps the clamping rod 520 together with the upper fixed clamp 416. At this time, open the valve 7 again to replenish the material. The receiving tray 8 guides the asphalt into the storage cylinder 511.

[0049] This application can be used in the field of road engineering maintenance machinery, or in other fields applicable to this application.

[0050] In another embodiment: Reference Figure 4-5 A bridge and road maintenance and repair construction device is applied to the field of road engineering maintenance machinery. The side walls of the fixed frame 410 are respectively fixed with an L-shaped inner limit frame 411 and an L-shaped outer limit frame 412. The horizontal part of the L-shaped placement frame 414 is provided with side grooves 420 on both sides. The side grooves 420 cooperate with the L-shaped outer limit frame 412 on the same side. The L-shaped inner limit frame 411 cooperates with the clamping rod 520.

[0051] For the transfer work, after the operation is completed, the motor connecting the threaded rod 415 is started to rotate, and the lifting seat 413 drives the L-shaped placement frame 414 to rise to the middle part. At this time, the clamping rod 520 enters the inner side of the L-shaped inner limit frame 411 welded to the side wall of the fixed frame 410, thereby restricting the horizontal movement of the grouting machine 5.

[0052] When there is still residual material to be recovered, the threaded rod 415 is driven to raise the lifting seat 413 based on the above steps. When the side groove 420 of the horizontal part of the L-shaped placement frame 414 is completely disengaged from the L-shaped outer limit frame 412, the staff can manually push the L-shaped placement frame 414 to rotate around the lifting seat 413. At this time, the opening of the storage cylinder 511 faces the upper part of the storage bucket 2, so that the remaining asphalt flows back into the storage bucket 2.

[0053] refer to Figure 1 The storage bin 2 is equipped with a top cover 6, and the top of the top cover 6 and the cover plate 512 are equipped with corresponding handles 513 to facilitate manual opening by operators.

[0054] However, as is well known to those skilled in the art, the working principles and wiring methods of motors and mixers are conventional or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
