Description

Technical Field

[0001] This invention relates to the field of structural beam maintenance technology, specifically to structural beam maintenance systems and methods. Background Technology

[0002] A structural beam is a structural component with a certain length. For example, some structural beams are 50-60 meters long or even longer, including high-speed rail structural beams and bridge structural beams. They are made of steel bars and concrete and have a flat upper surface. Generally, there are supporting components in the middle part of the lower surface.

[0003] Newly manufactured structural beams require curing, which involves sprinkling water on them. The curing period is typically close to one month, with the first week being particularly crucial to ensure the beams fully solidify and maintain their strength.

[0004] In existing technologies, the timing of watering structural beams is manually controlled. Sometimes the curing is carried out at certain intervals, and sometimes it is carried out by observing the dryness and wetness of the structural beams. This has the disadvantages of low automation and inconvenience in use.

[0005] Therefore, it is necessary to improve this. Summary of the Invention

[0006] The purpose of this invention is to address the above-mentioned shortcomings by providing an automated and user-friendly structural beam maintenance system and method.

[0007] The technical solution of the structural beam curing system of this invention is implemented as follows: The structural beam curing system includes a structural beam and a curing device. The structural beam is a long, rectangular precast concrete block. The curing device includes a traveling trolley with wheels driven by an electric motor. In use, the traveling trolley is placed on the structural beam to be cured and can travel from one end of the beam to the other. The electric motor is connected to a power source via a control device. A water tank is installed on the traveling trolley, and an extension arm is also installed on the traveling trolley. A water spray pipe is installed on the extension arm via a connector. The water spray pipe has multiple spray holes, which spray curing water onto the surface of the structural beam to be cured. The surface includes at least one of an upper surface, a side surface, and a lower surface; the water spray pipe is connected to a water tank via a valve; the valve is connected to a control device; the water tank, valve, and water spray pipe form a curing system; characterized in that: a surface moisture tester is placed on the structural beam, the tester can measure the surface moisture of the structural beam, the measured surface moisture is a measured value, the tester is connected to the control device, when the humidity or water content measured by the tester is less than a set value, the humidity or water content being less than the set value is the value requiring curing, the tester transmits the measured value or this signal to the control device, the control device activates the curing device to work.

[0008] Furthermore, there are multiple testing instruments distributed at various locations on the structural beam. Each testing instrument transmits its measured values ​​to the control device. The testing instrument whose measured value reaches the level requiring maintenance is an alarm testing instrument. The control device obtains the proportion of alarm testing instruments among all testing instruments. This proportion is the alarm ratio. When the alarm ratio is greater than a certain value, the control device activates the maintenance device to start operation.

[0009] Furthermore, the testing instruments mentioned include, but are not limited to, humidity testers and infrared moisture detectors.

[0010] Furthermore, the testing instrument is equipped with a trolley below it, which is connected to a control device. The control device can control the operation of the trolley, and the measured value refers to the average value measured by the trolley during operation.

[0011] Furthermore, under the control of the control device, the traveling vehicle advances two unit lengths and then retreats one unit length. The two unit lengths of advancing are the first unit behind and the second unit in front, and then it advances two unit lengths again, and so on. When the traveling vehicle advances to the second unit, the maintenance system performs the first maintenance on the structural beam. When the traveling vehicle advances to the first unit, the maintenance system performs the second maintenance on the structural beam.

[0012] Furthermore, the maintenance system includes two maintenance systems: a first maintenance system and a second maintenance system, with the valves connected to a control device. The water tank of the first maintenance system contains maintenance water containing adhesive; the water tank of the second maintenance system contains clean maintenance water. During the first maintenance, the control device opens the valve of the first maintenance system and closes the valve of the second maintenance system. During the second maintenance, the control device opens the valve of the second maintenance system and closes the valve of the first maintenance system.

[0013] Furthermore, the water tank of the maintenance system also has a temperature regulating device on its side. The structural beam maintenance device also includes a temperature measuring device. The temperature measuring device is connected to the control device, and the temperature regulating device is connected to the control device. The control device controls the temperature regulating device to make the temperature inside the water tank of the maintenance system approach the temperature measured by the temperature measuring device.

[0014] Furthermore, when the vehicle is moving backward, the maintenance system performs backward maintenance on the structural beam; during backward maintenance, the control device opens the valve of the second maintenance system and closes the valve of the first maintenance system; the backward maintenance sprays less curing water per unit area of ​​the structural beam than the initial maintenance sprays less curing water per unit area of ​​the structural beam.

[0015] The technical solution of the structural beam maintenance method of the present invention is as follows: The structural beam maintenance method uses a surface moisture tester to measure the moisture content on the surface of the structural beam. When the measured moisture content on the structural beam is lower than a set value, the maintenance device is automatically activated.

[0016] Furthermore, there are multiple testing instruments distributed at various locations on the structural beam. Each testing instrument transmits its measured values ​​to the control device. The testing instrument whose measured value reaches the level requiring maintenance is an alarm testing instrument. The control device obtains the proportion of alarm testing instruments among all testing instruments. This proportion is the alarm ratio. When the alarm ratio is greater than a certain value, the control device activates the maintenance device to start operation.

[0017] Furthermore, the testing instrument is operational, and the measured value refers to the average value measured by the testing instrument during operation.

[0018] To elaborate further, when curing structural beams, first spray curing water onto one end of the surface of the structural beam, then return to perform a second curing. The return trip is half the distance of the forward trip, and this process is repeated until the structural beam is cured from one end to the other.

[0019] To elaborate further, the curing water used for the initial curing of the structural beam is curing water containing adhesive, while the curing water used for the secondary curing of the structural beam is clean water.

[0020] Furthermore, the curing water used during the initial curing of the structural beam is curing water with a temperature close to that of the structural beam.

[0021] Furthermore, when the vehicle is moving backward, the maintenance system performs backward maintenance on the structural beam; the backward maintenance sprays less maintenance water per unit area of ​​the structural beam than the initial maintenance sprays.

[0022] The beneficial effects of this invention are that such a beam maintenance system and structural beam maintenance method have the advantages of automatic control and ease of use. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] The structural beam curing device of the present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1 , 2As shown in Figure 4, the structural beam curing system includes a structural beam 10 and a curing device 20. The structural beam is a long, rectangular precast concrete block. The curing device includes a traveling vehicle 1 with wheels 11 driven by an electric motor. In use, the traveling vehicle is placed on the structural beam to be cured and can travel from one end to the other. The electric motor is connected to a power source via a control device. A water tank 12 is installed on the traveling vehicle, as is an extension arm 13. A water spray pipe 15 is installed on the extension arm via a connector 14. The water spray pipe has multiple spray holes 16 that spray curing water onto the surface of the structural beam to be cured. The surface described includes at least one of an upper surface, a side surface, and a lower surface; the water spray pipe is connected to a water tank via a valve; the valve is connected to a control device 19; the water tank, valve, and water spray pipe form a curing system; characterized in that: a surface moisture tester 31 is placed on the structural beam, the tester can measure the surface moisture of the structural beam, the measured surface moisture is a measured value, the tester is connected to the control device, when the humidity or water content measured by the tester is less than a set value, the humidity or water content being less than the set value is the value requiring curing, the tester transmits the measured value or this signal to the control device, the control device starts the curing device to work.

[0031] This invention uses a testing instrument (also called a detection device) to test the moisture content on the structural beams, rather than relying on manual observation of the moisture level to determine whether maintenance is needed, or requiring maintenance after a certain period of time. This makes it convenient to use, allows for automated maintenance, and achieves the intended purpose of this invention.

[0032] The tester can be connected to the control device via an electrical connection or a network connection, as long as it can transmit the tester's signals to the control device.

[0033] Furthermore, there are multiple testing instruments distributed at various locations on the structural beam. Each testing instrument transmits its measured values ​​to the control device. The testing instrument whose measured value reaches the level requiring maintenance is an alarm testing instrument. The control device obtains the proportion of alarm testing instruments among all testing instruments. This proportion is the alarm ratio. When the alarm ratio is greater than a certain value, the control device activates the maintenance device to start operation.

[0034] For example, the alarm testers account for a certain proportion of 40%, and there are a total of 10 testers. Among them, the measured values ​​of 5 testers have reached the level that requires maintenance. These 5 testers are called alarm testers (also known as red camp testers). That is, the 50% that need maintenance will be activated by the control device.

[0035] This invention is designed to make the measured values ​​obtained by the control device more accurate, thus avoiding the disadvantage of inaccurate measurements from a single testing instrument.

[0036] Furthermore, the testing instruments mentioned include, but are not limited to, humidity testers and infrared moisture detectors.

[0037] For example, a humidity meter can measure the humidity on a structural beam and determine whether the beam contains moisture based on the humidity; another example is the infrared moisture detector, which can detect images on a structural beam and determine whether the beam contains moisture based on the images.

[0038] Furthermore, the testing instrument is equipped with a trolley 32 below it. The trolley is connected to a control device, which can control the operation of the trolley. The measured value refers to the average value measured by the trolley during operation.

[0039] This invention allows the control device to obtain more accurate measured values, avoiding the drawback of the tester measuring inaccurately at one location.

[0040] To elaborate further, such as Figure 3 Under the control of the control device, the traveling vehicle advances two unit lengths and then retreats one unit length. The two unit lengths of advancing are the first unit behind and the second unit in front, and then it advances two unit lengths again, and so on. When the traveling vehicle advances to the second unit, the maintenance system performs the first maintenance on the structural beam. When the traveling vehicle advances to the first unit, the maintenance system performs the second maintenance on the structural beam.

[0041] For ease of understanding, Figure 3 The length of A in the diagram is the length of one unit. a1, a2, a3, a4, a5, a6, a7, and a8 represent the order and direction of the movement of the vehicle. k1 in the diagram is the first unit, and k2 is the second unit.

[0042] The above-mentioned configuration of the present invention enables the first curing to be performed, followed by a second curing of the structural beam. The short interval between the two curing processes can, on the one hand, increase the water storage capacity of the structural beam, and on the other hand, reduce the damage to the structural beam caused by the temperature difference between the structural beam and the curing water by dividing the curing process into two stages. This is because after the first curing of the structural beam, the surface temperature of the structural beam is closer to the temperature of the curing water.

[0043] This structural beam curing device has two curing systems (M and N), namely the first curing system M and the second curing system N; the water tank of the first curing system contains curing water containing adhesive; the water tank of the second curing system contains clean curing water; during the first curing and the second curing, the different curing systems in the first and second curing systems are activated.

[0044] In one embodiment, the activation of the different maintenance systems in the first maintenance system and the second maintenance system refers to: during the first maintenance, the control device opens the valve of the first maintenance system and closes the valve of the second maintenance system; during the second maintenance, the control device opens the valve of the second maintenance system and closes the valve of the first maintenance system.

[0045] This invention is designed so that the curing water sprayed during the initial curing process contains a colloid, which can improve the adhesion of the curing water to the structural beam, especially when the curing water is sprayed on the underside of the structural beam, thus reducing the amount of curing water falling off.

[0046] The adhesive used can be, for example, cellulose, starch, or anything else that has adhesive properties. Water is used for the secondary curing process, which saves on adhesive and reduces contamination.

[0047] In one embodiment, the amount of adhesive used is 0.3-0.5% of the water mass.

[0048] In another embodiment, the activation of the different maintenance systems in the first and second maintenance systems refers to: during the first maintenance, the control device opens the valve of the second maintenance system and closes the valve of the first maintenance system; during the second maintenance, the control device opens the valve of the first maintenance system and closes the valve of the second maintenance system.

[0049] This invention is designed so that the curing water sprayed during the initial curing is clean water, which reduces the penetration of adhesives in the second curing water into the structural beam and thus reduces its strength. The curing water sprayed during the second curing contains adhesives, which can improve the adhesion of the curing water to the structural beam, especially when the curing water is sprayed on the bottom of the structural beam, thus reducing the amount of curing water dripping.

[0050] In another embodiment, the structural beam curing device has two curing systems: a K curing system and an L curing system. The water tank of the K curing system contains curing water containing adhesive, and the spray nozzles of the K curing system's spray pipes are only upward-facing, spraying the curing water only onto the lower part of the structural beam. The water tank of the second curing system contains clean curing water. The spray nozzles of the L curing system's spray pipes are only sideways and downward-facing, spraying the curing water only onto the sides and top of the structural beam.

[0051] In this embodiment, since only the curing water on the surface below the structural beam still drips, it is necessary to use curing water with higher viscosity on the surface below the structural beam, as this water is easily absorbed by the surface of the structural beam, thus prolonging the curing time; while it is not necessary to use curing water with higher viscosity on the surface of the structural beam, clean water can be used to save costs.

[0052] To elaborate further, such as Figure 4 As shown, the water tank of the maintenance system also has a temperature regulating device on its side. This structural beam maintenance device also includes a temperature measuring device. When in use, the temperature measuring device contacts the structural beam and can measure the temperature of the structural beam. The temperature measuring device is connected to the control device, and the temperature regulating device is connected to the control device. The control device controls the temperature regulating device to make the temperature inside the water tank of the maintenance system approach the temperature measured by the temperature measuring device.

[0053] The temperature control device includes a heating device and a cooling device. The heating device is, for example, an electric heating wire connected to a power source, and the cooling device is, for example, a refrigeration component, as long as it can adjust the temperature inside the water tank.

[0054] This invention allows the curing water used during maintenance to be close to the temperature of the structural beam, reducing the adverse effects of temperature differences between the curing water and the structural beam. For example, it minimizes damage to the structural beam and improves the quality of maintenance.

[0055] Furthermore, when the vehicle is moving backward, the maintenance system performs backward maintenance on the structural beam; during backward maintenance, the control device opens the valve of the second maintenance system and closes the valve of the first maintenance system; the backward maintenance sprays less curing water per unit area of ​​the structural beam than the initial maintenance sprays less curing water per unit area of ​​the structural beam.

[0056] This invention allows for the replenishment of curing water to the structural beams during the subsequent curing process, thereby extending the curing cycle and improving the quality of curing.

[0057] It should be noted that, for ease of understanding, the above-described embodiment of a structural beam curing device can also provide a useful supplement to the structural beam curing method; any unclear points in the following structural beam curing method can also be found in the above-described embodiment of the structural beam curing device.

[0058] Furthermore, the device also includes a guide rail 18 mounted on the structural beam. The wheels have a structure for mounting on the guide rail. When the device is in use, the guide rail is laid on the structural beam to ensure the correct operation of the vehicle.

[0059] The structural beam curing method uses a surface moisture tester to measure the moisture content on the surface of the structural beam. When the measured moisture content on the structural beam is lower than a set value, the curing device is automatically activated.

[0060] Furthermore, there are multiple testing instruments distributed at various locations on the structural beam. Each testing instrument transmits its measured values ​​to the control device. The testing instrument whose measured value reaches the level requiring maintenance is an alarm testing instrument. The control device obtains the proportion of alarm testing instruments among all testing instruments. This proportion is the alarm ratio. When the alarm ratio is greater than a certain value, the control device activates the maintenance device to start operation.

[0061] Furthermore, the testing instrument is operational, and the measured value refers to the average value measured by the testing instrument during operation.

[0062] To elaborate further, when curing structural beams, first spray curing water onto one end of the surface of the structural beam, then return to perform a second curing. The return trip is half the distance of the forward trip, and this process is repeated until the structural beam is cured from one end to the other.

[0063] Furthermore, the amount of curing water sprayed per unit area of ​​the structural beam during the initial curing is less than the amount of curing water sprayed per unit area during the secondary curing.

[0064] To elaborate further, the curing water used for the initial curing of the structural beam is curing water containing adhesive, while the curing water used for the secondary curing of the structural beam is clean water.

[0065] Furthermore, the curing water used during the initial curing of the structural beam is curing water with a temperature close to that of the structural beam.

[0066] Furthermore, when the vehicle is moving backward, the maintenance system performs backward maintenance on the structural beam; the backward maintenance sprays less maintenance water per unit area of ​​the structural beam than the initial maintenance sprays.

[0067] In one embodiment, the structural beam maintenance method uses the structural beam maintenance system of the present invention.

[0068] It should be noted that: in this invention, the embodiments and technical effects of the structural beam maintenance system can be used to illustrate and explain the structural beam maintenance method; similarly, the technical effects of the structural beam maintenance method can also be used to illustrate and explain the structural beam maintenance system, which should be known by those skilled in the art.

[0069] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0070] In the description of the embodiments of the present invention, it should be noted that if the term "center" appears,

[0071] The terms "upper," "lower," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0072] Furthermore, the use of terms such as "horizontal" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0073] In the description of the embodiments of the present invention, "multiple" means at least two.

[0074] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.
