Description

Technical Field

[0001] The invention relates to the technical field of aqueduct maintenance, and in particular to a device for spraying and maintaining concrete of a large aqueduct body. Background Art

[0002] Aqueducts are overhead water channels that carry water across rivers, valleys, depressions and roads. They are commonly used for irrigation and water delivery, as well as flood and sand drainage. Large aqueducts can also be navigable.

[0003] The aqueduct body mainly adopts a prestressed U-shaped trough body structure. The construction of the aqueduct body is mainly divided into three construction processes: trough making machine casting method; hanging basket cantilever casting method; bracket cast-in-place method. Among them, the Laowuba Aqueduct, Tangjiaba Aqueduct and other tall aqueducts mainly adopt the trough making machine casting method. After the concrete is demoulded, the conventional curing process of the trough body concrete adopts artificial sprinkling curing.

[0004] Since the aqueduct body is an overhead structure with a maximum overhead height of over 90m and a maximum span of 42m, high-altitude maintenance of the concrete on the outside of the body is difficult. The maintenance water mainly relies on gravity flow to various parts of the concrete, resulting in inadequate maintenance in some areas and difficulty in ensuring the quality of concrete. In addition, manual watering maintenance operations at high altitudes for a long time pose a high safety risk. Summary of the invention

[0005] The invention provides a device for spraying and curing concrete of a high-rise aqueduct body, aiming to automatically spray and cure the body of the high-rise aqueduct body at the outer side thereof.

[0006] The present invention is implemented by the following technical scheme: a device for spraying and curing concrete of a high aqueduct body, comprising:

[0007] A main beam, wherein two main beams are provided and the two main beams are arranged parallel to each other;

[0008] A tie beam, wherein a plurality of tie beams are provided, and the plurality of tie beams are sequentially distributed along the two main beams, and both ends of the tie beams are respectively fixedly connected to the two main beams;

[0009] Tracks, the tracks are provided in two rows, the two rows of tracks are respectively arranged on both sides of the top of the aqueduct body, the two main beams are arranged perpendicular to the tracks and slide along the two rows of tracks;

[0010] A water tank, the water tank being installed on the top ends of the two main beams;

[0011] Spray pipes, two of which are respectively located on both sides of the aqueduct body, with a gap between the spray pipes and the aqueduct body; the upper portion of the spray pipe is connected to the main beam; the water tank and the spray pipe are connected through a pipeline, and a booster pump is connected to the pipeline; a plurality of nozzles are installed on the spray pipe.

[0012] Compared with the prior art, this solution has the following advantages and beneficial effects:

[0013] In this solution, by moving the main beam on the track, the two spray pipes can be driven to move along the length of the aqueduct body, so as to facilitate spraying the outside of the aqueduct body. Compared with traditional manual watering maintenance, this solution uses spray pipes and nozzles for spraying, which effectively improves the maintenance efficiency, greatly shortens the manual maintenance time, speeds up the construction progress, and reduces labor costs.

[0014] Compared with the traditional manual watering maintenance method, the concrete spraying maintenance system in this solution greatly reduces the safety risk. Especially in the maintenance process of the concrete outside the high aqueduct body, the safety risk of manual high-altitude maintenance construction is very high. This solution can control the main beam to move automatically along the track by adding an automatic control system, thereby driving the movement of the spray pipe, thereby achieving the spray maintenance of the aqueduct body, significantly reducing manual operations, thereby reducing the safety risks caused by human factors.

[0015] Furthermore, the shape of the spray pipe matches the outer contour of the aqueduct body, and the plurality of spray heads are distributed at intervals along the length direction of the spray pipe.

[0016] Beneficial effect: Such an arrangement can provide comprehensive and sufficient spray maintenance for the aqueduct body, and can cover the entire concrete surface of the aqueduct body.

[0017] Furthermore, the upper part of the spray pipe is located between the two main beams, and the upper part of the spray pipe is vertically connected to a rotating rod, and the two ends of the rotating rod are respectively rotatably cooperated with the two main beams; the tie beam is connected to a driving member for pushing or pulling the spray pipe to rotate.

[0018] Beneficial effects: when the entire device needs to move to the next span of the trough for spraying maintenance, it is necessary to cross the trough platform at the end of the trough body. At this time, the driving part in this scheme drives the spray pipe to rotate, so that the spray pipe is stretched and expanded, ensuring the safe passage of the spray pipe and avoiding the trough platform from hindering its movement.

[0019] Furthermore, the driving member is an electro-hydraulic push rod.

[0020] Beneficial effect: In this solution, the driving part adopts an electro-hydraulic push rod, and the electric drive or hydraulic drive push rod action can be selected according to the actual situation on site. It is easy to use, has stable force, and has a more stable drive for the sprinkler pipe.

[0021] Furthermore, the nozzle is movably connected to the spray pipe.

[0022] Beneficial effect: In this solution, the nozzle and the spray pipe are movably connected, so that the spray angle of the nozzle can be adjusted according to actual needs, which is more practical.

[0023] Furthermore, both ends of the track are connected to limiting members, and both end bottoms of the main beam are installed with walking units, and the walking units are slidably matched with the track.

[0024] Beneficial effects: The limiters connected at both ends of the track in this solution can prevent the main beam from derailing during operation, and the walking unit in this solution can reduce the friction between the main beam and the track, making the main beam smoother during operation, and can further enhance the guiding effect on the movement of the main beam, ensuring the linear movement of the main beam.

[0025] Furthermore, a plurality of reinforcement rods are connected between the two rows of tracks, and the plurality of reinforcement rods are sequentially distributed along the length direction of the track.

[0026] Beneficial effect: In this solution, reinforcing rods are connected between the two rows of tracks, which can ensure that the tracks do not deviate during operation, thereby ensuring the stability of the main beam running on the track.

[0027] Furthermore, the reinforcement rod is detachably connected to the track.

[0028] Beneficial effect: Such arrangement facilitates installation and disassembly.

[0029] Furthermore, two limit rods are connected to the reinforcement rod, and the two limit rods are respectively clamped on the inner side of the aqueduct body.

[0030] Beneficial effect: In this solution, two limit rods are connected to the reinforcement rod, which can limit the limit rods to the inner side of the aqueduct body, thus ensuring that the two rows of tracks will not be offset as a whole, thereby further improving the stability and accuracy of the main beam operation.

[0031] Furthermore, it also includes a controller, which is electrically connected to the boost pump.

[0032] Beneficial effect: In this scheme, the start and stop of the booster pump is controlled by the controller, thereby controlling the spraying action of the spray pipe, so that the purpose of automatic control can be achieved, the overall work efficiency is improved, and it is more automated, saving labor costs.

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0043] Example 1

[0044] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment 1 provides a device for spraying and curing concrete of a high aqueduct body, comprising:

[0045] Main beam 1, two main beams 1 are provided, the two main beams 1 are arranged parallel to each other, and the main beam 1 is made of I20a I-beam;

[0046] A tie beam 2, wherein a plurality of tie beams 2 are provided, and the tie beams 2 are made of I20a I-beams, and the plurality of tie beams 2 are sequentially distributed along the length direction of the two main beams 1, and the two ends of the tie beams 2 are respectively welded and fixedly connected with the two main beams 1, and after the plurality of tie beams 2 and the two main beams 1 are welded together, they serve as a supporting skeleton of the entire spray curing device;

[0047] Track 3, track 3 is provided with two rows, track 3 in this embodiment is a steel rail, as the track 3 of the whole spray curing device; Figure 3 , Figure 4 and Figure 5 As shown, two rows of tracks 3 are respectively arranged on both sides of the top of the aqueduct body, and two main beams 1 are arranged vertically with the tracks 3 and slide along the two rows of tracks 3. In this embodiment, both ends of the tracks 3 are connected with limiting members, which are limiting blocks. The limiting blocks are welded or bolted to the tracks 3, and the limiting blocks can prevent the main beam 1 from derailing during the operation on the tracks 3; Figure 1 and Figure 2 As shown, a walking unit 12 is installed at the bottom of both ends of the main beam 1. The walking unit 12 is slidably matched with the track 3. The walking unit 12 includes a walking wheel, which is connected to the bottom of the main beam 1 and moves along the track 3.

[0048] Water tank 7, the water tank 7 is installed at the top of the two main beams 1. In this embodiment, the water tank 7 can be directly placed on the top of the main beam 1 and located on the tie beam 2 between the two main beams 1, and can also be reinforced by bolts;

[0049] Spray pipe 4, two spray pipes 4 are provided, and the spray pipes 4 are seamless steel pipes. The two spray pipes 4 are respectively located on both sides of the aqueduct body, and there is a gap between the spray pipe 4 and the aqueduct body. In this embodiment, the shape of the spray pipe 4 matches the outer contour of the aqueduct body, and the distance between the spray pipe 4 and the aqueduct body is 1m;

[0050] The upper part of the spray pipe 4 is connected to the main beam 1. Specifically: Figure 3 and Figure 4 As shown, in this embodiment, the upper part of the spray pipe 4 is located between the two main beams 1, and the upper part of the spray pipe 4 is vertically connected with a rotating rod 40, the rotating rod 40 and the spray pipe 4 are integrally formed, and the two ends of the rotating rod 40 are respectively rotatably matched with the two main beams 1. In this embodiment, through holes are opened on the opposite sides of the two main beams 1, and the ends of the two main beams 1 are respectively inserted into the through holes and can rotate in the through holes;

[0051] The tie beam 2 is connected with a driving member for pushing or pulling the spray pipe 4 to rotate. In this embodiment, the driving member is an electro-hydraulic push rod 6. Figure 2 As shown, the electro-hydraulic push rod 6 can stretch and unfold the spray pipe 4, with an unfolding angle of 56°, and the distance from the trough platform at both ends of the aqueduct body is 50cm, which can ensure safe and smooth passage;

[0052] Since both ends of the aqueduct body have trough platforms, and the width of the trough platforms is greater than the width of the aqueduct body, when the spray curing device in this embodiment moves to the next span of the aqueduct body for spray curing, the trough platforms will hinder the movement of the spray pipes 4 on both sides of the aqueduct body; however, in this embodiment, only one spray curing device is required. When it is necessary to move to the next span of the aqueduct body for spray curing, the spray pipe 4 is stretched and unfolded by the electro-hydraulic push rod 6, and smoothly crosses the trough platform at the end of the aqueduct body, thereby achieving safe passage;

[0053] The water tank 7 is connected to the spray pipe 4 through a pipeline, and a booster pump 8 is connected to the pipeline. Two booster pumps 8 are provided. The two booster pumps 8 are respectively installed on the tie beam 2 and are located on both sides of the water tank 7. In this embodiment, the booster pump 8 can be directly placed on the tie beam 2, and can also be reinforced by bolts.

[0054] The pipeline between the water tank 7 and the spray pipe 4 is a hose 9, and the length of the hose 9 is relatively long, which can adapt to the movement of the spray pipe 4; a plurality of nozzles 5 are installed on the spray pipe 4, and the nozzles 5 are high-pressure spray nozzles 5. In this embodiment, the nozzles 5 are welded and fixed to the spray pipe 4; the plurality of nozzles 5 are distributed at intervals along the length direction of the spray pipe 4, so that the plurality of nozzles 5 are arranged along the outer contour of the aqueduct body, and can cover the concrete surface of the entire body of the aqueduct, such as Figure 1 As shown, the arrow indicates the direction of water flow in the water tank spray pipe in the water tank.

[0055] Since the diameter of the high-pressure nozzle 5 in this embodiment is relatively small, if there are many impurities in the curing water during the curing process, the nozzle may be blocked, affecting the curing quality. The curing water needs to be pumped into the curing water bucket in advance for sedimentation, and an appropriate amount of water purifier is added. Finally, the treated curing water is pumped into the water tank 7 of the spray curing device for concrete curing.

[0056] Further, in another embodiment, Figure 1 , Figure 4 and Figure 5 As shown, a plurality of reinforcing rods 10 are connected between the two rows of tracks 3, and the plurality of reinforcing rods 10 are sequentially distributed along the length direction of the track 3, with a spacing of 5m between the reinforcing rods 10, and a total of 9 are provided. The provision of the reinforcing rods 10 can ensure that the track 3 does not deviate during operation. In this embodiment, the reinforcing rods 10 are detachably connected to the track 3, specifically: the reinforcing rods 10 are connected to the track 3 by threads, which is convenient for installation and disassembly;

[0057] Two limit rods 11 are connected to the reinforcement rod 10, and the two limit rods 11 are respectively welded vertically to the left and right parts of the reinforcement rod 10. The two limit rods 11 are respectively clamped on the inner side of the aqueduct body, which can limit the track 3 and ensure that the two rows of tracks 3 are not offset as a whole, thereby ensuring the stability of the entire spray maintenance device during operation.

[0058] The specific implementation process is as follows: inject appropriate clean water into the water tank 7, turn on the booster pump 8 to debug the water spraying state of the spray pipe 4. According to the test results, the water spraying amount of the spray head is appropriately adjusted. Since the overhead height of the first span tank body is relatively low, a crank arm lifting platform vehicle can be used to cooperate with manual adjustment of the spray head.

[0059] After the entire spray curing device is debugged and running normally, the spray curing device will be moved to the tank body section to be maintained for automatic spray curing construction, and a special person will be assigned to record the operation of the first curing process, including the overall wetness of the tank body during curing, the coverage rate of the tank body spray curing, the duration of each curing cycle, the use time of 7 water in the water tank, etc. If any abnormality is found during the process, the power supply will be disconnected immediately to investigate the cause.

[0060] Move to the next span for cyclic operation: After the maintenance of the previous span is completed, move to the next span to continue maintenance construction. Track 3 uses manual or crane combined with manual reversing of rails to gradually move the spray maintenance device to the next span. During the movement, the electro-hydraulic push rod 6 pulls the spray pipe 4, so that the spray pipe 4 is in an expanded state, which is convenient for smooth passage through the trough platform at the end of the trough body. Since the cross-section of the trough platform is larger than the cross-section of the trough body, when the spray maintenance device moves toward the trough platform, the electro-hydraulic push rod 6 realizes the transmission of driving force through the hydraulic transmission principle, thereby stretching and unfolding the spray pipe 4, and locking it when it is stretched to the specified position to ensure that it passes through the trough platform safely and smoothly.

[0061] Example 2

[0062] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that: in this embodiment, the nozzle 5 is movably connected to the spray pipe 4, so that the angular position of the nozzle 5 can be adjusted, thereby adjusting the spray angle of the nozzle 5 according to actual needs. Specifically, a connector 501 is welded at the position where the nozzle 5 is installed on the spray pipe 4, and a rotating shaft 502 is rotatably engaged on the connector 501, and the nozzle 5 is connected to the rotating shaft 502, so that the nozzle 5 can be rotatably engaged with the connector 501 through the rotating shaft 502, thereby facilitating the adjustment of the spray angle of the nozzle 5.

[0063] Example 3

[0064] The difference between this embodiment and embodiment 1 is that: a device for spraying and maintaining concrete of a large aqueduct in this embodiment also includes a controller, which is electrically connected to the booster pump 8; the walking unit 12 in this embodiment also includes a walking motor, the output end of the walking motor is connected to the walking wheel, a support is connected to the bottom of the main beam 1, the walking wheel is rotatably connected to the support at the bottom of the main beam 1, the walking motor is installed on the main beam 1, and the walking motor can drive the walking wheel to move along the track 3. In this embodiment, the walking motor is electrically connected to the controller.

[0065] In this embodiment, the controller can control the start and stop of the walking unit 12 and the booster pump 8 to achieve the function of automatically controlling the spraying and reciprocating walking, which is more automated.

[0066] Compared with the traditional manual watering curing method, the present invention's spray curing device for high-rise aqueduct body concrete greatly reduces safety risks. Especially in the curing process of the concrete outside the high-rise aqueduct body, the safety risk of manual high-altitude curing construction is very high. The automatic spraying system significantly reduces manual operation through its intelligent operation and automated control, thereby reducing safety risks caused by human factors.

[0067] In addition, the spray maintenance device is equipped with an automatic reciprocating walking unit 12, which is convenient to move and simple to operate, thus reducing the input of personnel and further reducing the safety risk.

[0068] The supporting facilities required for the automatic sprinkler system are all small and movable. The production and installation process of the equipment is relatively simple. The whole system is highly operational and easy to use. The whole device is easy to install and disassemble, which is convenient for internal turnover within the construction site or use in other similar projects of the unit.

[0069] The structure and size of the spray curing device can be modified according to the cross-section of the aqueduct body in different flow sections. The number of spray curing devices can be increased according to the on-site construction intensity to improve the convenience of construction.
