Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and in particular to a maintenance device. Background Technology

[0002] A bridge is a structure built to cross natural or man-made obstacles, spanning rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, substructure, and ancillary structures. The superstructure mainly refers to the span structure and bearing system; the substructure includes abutments, piers, etc. After construction, bridges require maintenance and upkeep.

[0003] Bridge expansion joints are an important structural component of bridge structures. After installation, they need to be fixed with cast-in-place concrete. The curing of the cast-in-place concrete at the expansion joint is an important part of the construction of the expansion joint, which directly affects the construction quality. If the curing is not done properly, quality problems such as insufficient concrete strength and cracks may occur at the expansion joint.

[0004] In existing traditional construction methods, to ensure proper curing of concrete at expansion joints, the common practice is to cover the joints with straw mats or geotextiles and then water them. This requires regular manual watering, which is labor-intensive and inefficient. Summary of the Invention

[0058] As shown in the figure, an embodiment of the present invention provides a maintenance device, including: a shell, a first sealing component 4, a second sealing component 5, a water tank 6, a maintenance mechanism 7, and a drive mechanism 8;

[0059] The housing includes a top plate 1, bottom plates 2 located on both sides of the top plate 1, and a support plate 3 located below the top plate 1; the bottom surface of the support plate 3 is higher than the bottom surface of the bottom plate 2 in the vertical direction.

[0060] The first sealing component 4 and the second sealing component 5 are respectively disposed at both ends of the housing;

[0061] The water tank 6 is located on the top surface of the support plate 3, and the water tank 6 is connected to the outside through the liquid injection hole provided by the first sealing component 4;

[0062] The maintenance mechanism 7 includes a mounting plate 71, a water spray pipe 72, and a water pump 73. The water spray pipe 72 is fixed to the mounting plate 71, and the water pump 73 connects the water tank 6 and the water spray pipe 72. The mounting plate 71 is located below the support plate 3.

[0063] The drive mechanism 8 is used to drive the mounting plate 71 to move, and the drive mechanism 8 is provided with a power source 81 to supply power to the water pump 73.

[0064] To address the problems existing in the prior art, this application provides a maintenance device, including a housing, a first sealing assembly 4, a second sealing assembly 5, a water tank 6, a maintenance mechanism 7, and a drive mechanism 8; wherein the housing is composed of a top plate 1, two bottom plates 2 on both sides, and a support plate 3 located below the top plate 1, and the first sealing assembly 4 and the second sealing assembly 5 are respectively provided at both ends of the housing; the bottom surface of the support plate 3 is set higher than the bottom surface of the bottom plate 2, so that when the housing is placed on the ground, the two bottom plates 2 are flat against the ground, and the two ends are sealed by the first sealing assembly 4 and the second sealing assembly 5. A space is formed below the support plate 3 to accommodate expansion joints or other areas requiring maintenance. A water tank 6 is installed on the top surface of the support plate 3, and the mounting plate 71 of the maintenance mechanism 7 and the connected spray pipe 72 are located below the support plate 3. Water is drawn from the water tank 6 by the water pump 73 and sprayed out through the spray pipe 72 to spray water onto the areas within the cavity below the support plate 3 for maintenance. The drive mechanism 8 drives the mounting plate 71, moving it along with the spray pipe 72, to evenly spray water onto all areas. This results in good maintenance effect, high efficiency, and effectively reduces labor intensity. The maintenance device provided in this application has a simple structure and reasonable design, and is particularly suitable for automated periodic maintenance of cast-in-place concrete with fixed bridge expansion joints.

[0065] The water tank 6 is connected to the outside through the injection hole provided by the first sealing component 4, and the construction personnel can replenish the water periodically.

[0066] The drive mechanism 8 is equipped with a power source 81 to power the water pump 73, which eliminates the need for an external power supply and facilitates use on construction sites.

[0067] Preferably, the maintenance mechanism 7 further includes a water suction pipe 74, a water delivery pipe 75, and a winding device 76;

[0068] One end of the suction pipe 74 is connected to the water tank 6, and the other end is connected to the water inlet of the water pump 73;

[0069] One end of the water supply pipe 75 is connected to the outlet of the water pump 73, and the other end is connected to the spray pipe 72;

[0070] The water supply pipe 75 is wrapped around the outer periphery of the winder 76, and the winder 76 provides pretension to keep the water supply pipe 75 taut.

[0071] To ensure a continuous water supply to the water tank 6 during the movement of the spray pipe 72, the maintenance mechanism 7 preferably includes a suction pipe 74, a delivery pipe 75, and a winding device 76. The suction pipe 74 connects the water tank 6 and the inlet of the water pump 73, and the delivery pipe 75 connects the outlet of the water pump 73 and the spray pipe 72. The length of the delivery pipe 75 is sufficient to wrap around the outer periphery of the winding device 76. The winding device 76 provides pre-tension to keep the delivery pipe 75 taut. During the movement of the spray pipe 72, the water pump 73 and the suction pipe 74 remain stationary, while the delivery pipe 75 is stretched or loosened as the spray pipe 72 moves. The loosened delivery pipe 75 is then wound up by the winding device 76. This satisfies the requirements for the movement and spraying of the spray pipe 72 without causing the delivery pipe 75 to hang on the ground and cause damage or obstruct the normal operation of the device.

[0072] Preferably, the water spray pipe 72 is provided with a plurality of atomizing nozzles 721; and / or,

[0073] The winding device 76 includes two fixed plates 761, and fixed sleeves 762 are respectively provided on the opposite side of the two fixed plates 761. A support shaft 763 is rotatably disposed between the fixed sleeves 762. The support shaft 763 is also connected to a coiling spring 764, which is in a pre-tightened state.

[0074] Preferably, the water spray pipe 72 is equipped with multiple atomizing nozzles 721 for more uniform water spraying. The length of the water spray pipe 72 can be set according to the width of the expansion joint to be maintained, etc. Preferably, the length of the water spray pipe 72 is equal to or slightly less than the distance between the two base plates 2. More preferably, the multiple atomizing nozzles 721 are evenly distributed and equidistantly installed on the water spray pipe 72.

[0075] The preferred winding device 76 has the following specific structure: two fixed plates 761, with fixed sleeves 762 on opposite sides of each fixed plate 761. A support shaft 763 is rotatably disposed between the fixed sleeves 762. One end of a coiling spring 764 is fixed in the fixed sleeve 762 and then sleeved onto the support shaft 763. The coiling spring 764 is in a pre-tightened state. When the drive mechanism 8 does not drive the mounting plate 71 to move, the elastic force of the coiling spring 764 keeps the water pipe 75 in a taut state. When the drive mechanism 8 operates and drives the spray pipe 72 to move away from the coiling spring 764, the driving force cancels out the elastic force, and the water pipe 75 is stretched and moves along with the spray pipe 72. During this process, the coiling spring 764 further deforms and accumulates elastic potential energy of the rebound. When the spray pipe 72 moves closer to the coiling spring 764, the loosened water pipe 75 is re-wound and retracted into the winding device 76 due to the force of the spring.

[0076] The water tank 6 is located above the support plate 3, the mounting plate 71 and the spray pipe 72 are located below the support plate 3, and the water pump 73, the suction pipe 74, the delivery pipe 75 and the winder 76 can be arbitrarily set above or below the support plate 3, and can pass through the support plate 3 through the hole; preferably, the water pump 73 and the suction pipe 74 are located above the support plate 3, the delivery pipe 75 passes through the support plate 3 and is wound around the winder 76 located below the support plate 3, and then connected to the spray pipe 72.

[0077] Preferably, the drive mechanism 8 further includes a power mechanism 82, a transmission mechanism 83, and a controller 84;

[0078] The transmission mechanism 83 includes a lead screw 831, a slider 832, a driving wheel 833, a driven wheel 834, and a transmission belt 835;

[0079] The power source 81 is connected to the power mechanism 82;

[0080] The power output end of the power mechanism 82 is fixedly connected to the driving wheel 833, the driven wheel 834 is fixedly connected to the lead screw 831, and the transmission belt 835 is wound around the outer periphery of the driving wheel 833 and the driven wheel 834.

[0081] The slider 832 is threadedly engaged with the lead screw 831, and the slider 832 is fixedly connected to the mounting plate 71;

[0082] The power source 81 and the power mechanism 82 are mounted on the support plate 3;

[0083] The controller 84 controls the operation of the power mechanism 82 and the water pump 73.

[0084] The preferred drive mechanism 8 also includes a power mechanism 82, a transmission mechanism 83, and a controller 84. The power mechanism 82 drives the transmission mechanism 83 by power provided by the power source 81. The transmission mechanism 83 includes a lead screw 831, a slider 832, a driving wheel 833, a driven wheel 834, and a transmission belt 835. The power output end of the power mechanism 82 is fixedly connected to the driving wheel 833, the driven wheel 834 is fixedly connected to the lead screw 831, and the transmission belt 835 is wound around the outer circumference of the driving wheel 833 and the driven wheel 834, realizing the rotation of the lead screw 831 through belt drive. The slider 832 is threadedly engaged with the lead screw 831, and the slider 832 is fixedly connected to the mounting plate 71, converting the rotation into the movement of the slider 732 and the mounting plate 71.

[0085] It also includes a controller 84 to control the operation of the power mechanism 82 and the water pump 73, enabling timed water spraying maintenance, and can also control the amount of water sprayed according to the settings.

[0086] In this application, the direction of movement of the maintenance mechanism 7 is determined by the axial direction of the lead screw 831. Preferably, the lead screw 831 is parallel to the edge where the two bottom plates 2 intersect with the top plate 1.

[0087] The slider 832 is fixedly connected to the mounting plate 71, so both the slider 832 and the screw 831 that is threaded together are located below the support plate 3. The power source 81 and the power mechanism 82 are mounted on the support plate 3, preferably above the support plate 3. The driven wheel 834 is located below the support plate 3, and the transmission belt 835 passes through the hole opened in the support plate 3 to realize power transmission.

[0088] In this application, the power source 81 is preferably a storage battery, and the power mechanism 82 is preferably a servo motor.

[0089] Preferably, the maintenance mechanism 7 further includes a humidity detection mechanism 77 and a water scraping mechanism 78;

[0090] The humidity detection mechanism 77 includes a lifting power mechanism 771, a connecting rod 772, and a humidity detector 773; the lifting power mechanism 771 is fixedly connected to the mounting plate 71 and drives the connecting rod 772 to rise and fall; the humidity detector 773 is fixedly connected to the connecting rod 772; the controller 84 receives the signal from the humidity detector 773 and controls the operation of the lifting power mechanism 771.

[0091] The wiping mechanism 78 includes a wiping lifting mechanism 781, a scraper 782, and a scraper strip 783; the wiping lifting mechanism 781 is fixedly connected to the mounting plate 71 and drives the scraper 782 to rise and fall; the scraper strip 783 is located at the bottom of the scraper 782; the controller 84 controls the operation of the wiping lifting mechanism 781; the first sealing component 4 and / or the second sealing component 5 are provided with drainage grooves 9.

[0092] A humidity detection mechanism 77 is preferably provided to detect the humidity of the maintenance target (such as cast-in-place concrete at expansion joints). When the humidity is lower than a preset value, the power mechanism 82 and water pump 73 are activated for water spraying maintenance. Specifically, the humidity detection mechanism 77 includes a lifting power mechanism 771, a connecting rod 772, and a humidity detector 773. The lifting power mechanism 771 is fixedly connected to the mounting plate 71 and drives the connecting rod 772 to rise and fall. The humidity detector 773 is fixedly connected to the connecting rod 772. The controller 84 receives the signal from the humidity detector 773 and controls the operation of the lifting power mechanism 771. The lifting power mechanism 771 drives the connecting rod 772 to rise and fall, causing the humidity detector 773 to move closer to or away from the ground (i.e., closer to or away from the part to be monitored). It descends during monitoring and maintains a distance from the ground when monitoring is not required to avoid damage to the humidity detector 773. The controller 84 receives the signal from the humidity detector 773 and controls the operation of the lifting power mechanism 771 based on the signal.

[0093] One or more humidity detectors 773 can be installed. For example, two can be installed at both ends of the connecting rod 772.

[0094] To prevent excessive water from affecting the maintenance effect, a squeegee mechanism 78 is also provided, and a corresponding drainage groove 9 is provided on the first sealing component 4 and / or the second sealing component 5. The squeegee mechanism 78 includes a squeegee lifting mechanism 781, a scraper 782, and a scraper strip 783; the squeegee lifting mechanism 781 is fixedly connected to the mounting plate 71 and drives the scraper 782 to rise and fall; the scraper strip 783 is located at the bottom of the scraper 782; the controller 84 controls the operation of the squeegee lifting mechanism 781. When excessive humidity is detected and squeegeeing is required, the squeegee lifting mechanism 781 drives the scraper 782 to fall, and the scraper strip 783 contacts the ground to squeegee water; when squeegeeing is not required, the gap between the scraper 782 and the scraper strip 783 and the ground is maintained.

[0095] The preferred method is to install the scraper 783 at an angle for better water removal. Furthermore, the lengths of the scraper 782 and scraper 783 are determined based on the width of the area to be maintained; preferably, the lengths of the scraper 782 and scraper 783 are equal to or slightly less than the distance between the two base plates 2.

[0096] Due to varying weather conditions, the amount of water required for spraying concrete areas differs. By incorporating a humidity detection mechanism 77 and a squeegee mechanism 78, along with the control of the water pump 73, the necessary moisture can be supplied in a targeted manner. Furthermore, the controller 84 receives signals and controls the corresponding mechanisms to achieve automated adjustments, further reducing labor intensity.

[0097] The humidity detection mechanism 77 and the squeegee mechanism 78 are fixedly connected to the mounting plate 71 and move with the mounting plate 71. They allow for gradual monitoring of the curing area and zoned spraying and squeegeeing operations, enabling area-specific spray curing. This effectively improves the curing results and avoids excessive water waste, which could affect concrete quality and conserve water resources. The squeegee mechanism 78 can squeegee water from high-humidity areas to low-humidity areas. If there is excessive water in the entire curing area, it will be drained from the drainage trough 9.

[0098] Preferably, the drainage trough 9 includes a guide plate 91 and a drainage channel 92;

[0103] The preferred water tank 6 is provided with a connecting pipe 61 and a guide hopper 62.

The guide hopper 62 is connected to the liquid injection hole provided by the first sealing component 4, and the liquid injection hole is also provided with a plug 411 (preferably a rubber plug).

[0104] When adding water, remove the plug 411 and add water through the injection hole. The water then flows through the guide hopper 62 and connecting pipe 61 into the water tank 6, facilitating long-term and sustainable use of the maintenance device provided in this application. Normally, the plug 411 is used to seal the injection hole to prevent debris from falling in.

[0105] Preferably, the top plate 1 has an arc, and support members for supporting the top plate 1 are respectively provided above the water tank 6 and above the support plate 3; the first sealing assembly 4 and the second sealing assembly 5 are respectively provided with a first reinforcing plate 43 and a second reinforcing plate 53.

[0106] To address the issue of traffic closures during maintenance, which inconveniences passing construction vehicles, this application also incorporates support components to ensure continued traffic flow during the maintenance device's operation. Specifically, the top plate 1 has an arc shape, reducing obstruction to the wheels. Support components supporting the top plate 1 are located above the water tank 6 and the support plate 3, respectively. The first sealing assembly 4 and the second sealing assembly 5 each contain a first reinforcing plate 43 and a second reinforcing plate 53, respectively, to ensure the device's strength and prevent damage.

[0107] The first sealing assembly 4 and the second sealing assembly 5 are respectively provided with a first reinforcing plate 43 and a second reinforcing plate 53, which can not only increase the compressive strength, but also make some of them into cavities to reduce the weight of the device, and at the same time facilitate the setting of the drainage groove 9.

[0108] The first reinforcing plate 43 and the second reinforcing plate 53 can be steel plates.

[0109] Preferably, a load-bearing plate 63 is provided above the water tank 6, and a plurality of elongated steel plates 64 are provided above the load-bearing plate 63.

[0110] The support plate 3 is provided with reinforcing ribs 31, and a support beam 32 is provided above the reinforcing ribs 31. The support beam 32 abuts against the top plate 1.

[0111] Furthermore, the water tank 6 is provided with a load-bearing plate 63 on top, and a plurality of long strip steel plates 64 are provided on top of the load-bearing plate 63.

A load-bearing block 66 is also provided on the outside of the side wall of the water tank 6, and the load-bearing block 66 is used to support the load-bearing plate 63.

[0112] A steel plate 64 is installed on the load-bearing plate 63. After the steel plate 64 abuts against the top plate 1 through the damping plate 65, the compressive strength of the maintenance device is effectively improved. The pressure is transmitted from the top plate 1 to the damping plate 65, the steel plate 64, the load-bearing plate 63, the load-bearing block 66, and then downwards, preventing the water tank 6 or other structures (such as the drive mechanism) from being damaged by passing cars. At the same time, the damping plate 65 can also play a role in buffering and shock absorption. In addition, the support plate 3 is provided with reinforcing ribs 31, and a support beam 32 is provided above the reinforcing ribs 31. The support beam 32 abuts against the top plate 1, further improving the compressive strength of the maintenance device.

[0113] The steel plate 64 and the damping plate 65 are in the shape of multiple long strips, which can not only resist pressure, but also reduce the weight of the device and reduce costs.

[0114] Damping plate 65 is a damping rubber plate. According to the curvature of the top plate 1, the height of the steel plate 64 and the damping plate 65 can be adjusted to achieve contact with the top plate 1 at various positions.

[0115] Preferably, the first sealing assembly 4 includes a first sealing housing 41 and two first insert plates 42, and the second sealing assembly 5 includes a second sealing housing 51 and two second insert plates 52; slots 21 are respectively provided at both ends of the base plate 2, and the first insert plates 42 and the second insert plates 52 respectively cooperate with the slots 21; and / or,

[0116] The base plate 2 is provided with mounting holes 22; the base plate 2 is also provided with a raised connecting plate 23 on the side near the top plate 1, and a positioning post 24 is provided below the connecting plate 23.

[0117] The first sealing assembly 4 and the second sealing assembly 5 are preferably assembled by inserting them into the base plate 2. Specifically, the first sealing assembly 4 includes a first sealing housing 41 and two first insert plates 42, and the second sealing assembly 5 includes a second sealing housing 51 and two second insert plates 52. The base plate 2 has slots 21 at both ends, and the first insert plates 42 and the second insert plates 52 respectively cooperate with the slots 21.

[0118] The preferred base plate 2 is provided with mounting holes 22, which makes it easy to fix the entire curing device to the bottom surface; the base plate 2 is also provided with a raised connecting plate 23 on the side near the top plate 1, and a positioning post 24 is provided below the connecting plate 23 for attaching geotextile, so as to facilitate curing by covering concrete with geotextile.

[0119] The maintenance device provided in this application is used as follows:

[0120] The mounting holes 22 on the base plate 2 are screwed to the ground using external bolts, and geotextile is fitted onto the positioning post 24 at the lower end of the connecting plate 23 to facilitate the curing of concrete by covering it with geotextile. Then, the first insert plate 42 and the second insert plate 52 are respectively engaged with the slots 21 on both sides of the base plate 2 to realize the assembly of the first sealing component 4 and the second sealing component 5.

[0121] After the water tank 6 is filled with water, the controller 84 activates the power mechanism 82 and the water pump 73 according to a preset program. The power mechanism 82 operates using the energy of the power source 81, driving the drive wheel 833 to rotate, which in turn drives the transmission belt 835 and the driven wheel 834 to rotate, thus rotating the lead screw 831. This causes the slider 832, which is threadedly engaged with the lead screw 831, and the mounting plate 71, which is fixedly connected to the slider 832, to move along the lead screw 831. During this process, the water pump 73 also operates using the power source 81, drawing water from the water tank 6 through the suction pipe 74 and then delivering it to the spray pipe 72 through the water delivery pipe 75. The water is then sprayed out through multiple atomizing nozzles 721, atomizing the geotextile on the concrete areas on both sides of the expansion joint. This allows the water to seep downwards along the fabric and be absorbed by the concrete, facilitating automated curing and improving curing efficiency. During the movement of the mounting plate 71, the winding device 76 maintains the tension of the water delivery pipe 75.

[0122] Due to varying weather and environmental conditions, the amount of water required for spraying in concrete areas differs. Before, during, or after water spraying, the controller 84 can control the lifting mechanism 771 to push the connecting rod 772, causing the humidity detector 773 to move downwards and contact the geotextile. This allows for gradual detection of the geotextile's humidity in the concrete area. When the humidity is within acceptable limits, no treatment is needed. When the humidity is too low and water needs to be added, the water pump 73 activates to spray water, improving efficiency and preventing excessive water waste that could affect concrete quality and water resources. Conversely, when the humidity is too high, the scraper lifting mechanism 781 activates, driving the scraper blades 783 on the scraper 782 to scrape water off the geotextile. The water flows with the scraper blades 783 to areas requiring additional water. When there are no areas requiring additional water, the scraper blades 783 continue to scrape water into the drainage trough 9 for discharge, preventing excessive humidity that could affect concrete quality and effectively avoiding excessive humidity during concrete curing, which could negatively impact the final molding quality.

[0123] Furthermore, the above operations can be started and stopped at regular intervals by the controller 84 to achieve automated maintenance.

[0124] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
