Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, in particular to a large-area concrete curing device. Background Art

[0002] Proper maintenance of concrete is a vital step in the concrete construction and maintenance process, which directly affects the strength, durability and service life of concrete.

[0003] During the curing process, one of the commonly used methods is to form a protective film on the concrete surface by spraying curing medium to reduce moisture evaporation and prevent cracks in the concrete due to too rapid drying.

[0004] Traditional concrete curing methods mostly use manual spraying with a handheld spray gun, which is not only inefficient but also difficult to ensure uniform spraying effect.

[0005] In order to improve efficiency and spraying quality, some automated large-area concrete curing devices have appeared on the market in recent years.

[0006] These devices usually include a supporting mechanism and a spraying mechanism. The supporting mechanism is used to span the upper part of the concrete to be cured, and the spraying mechanism is responsible for spraying the curing medium evenly on the concrete surface.

[0007] However, existing automated maintenance devices still have some problems during the spraying process.

[0008] For example, when the maintenance nozzle in the spraying mechanism is moving, the hose connected to it is easily pulled or piled up, which affects the uniformity and continuity of the spraying.

[0009] In addition, when the curing nozzle moves to the end of its stroke or encounters an obstacle, if the curing medium continues to flow, it will cause excessive spraying of the curing medium at a fixed position of the concrete, which will not only cause a waste of curing medium, but may also affect the appearance and quality of the concrete. Summary of the invention

[0010] The invention provides a large-area concrete curing device to solve the problem of excessive spraying of curing medium at a fixed position of concrete when movement of a curing nozzle is blocked.

[0011] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0012] A large-area concrete curing device comprises a displaceable curing nozzle, a storage mechanism and an adjustment mechanism;

[0013] The receiving mechanism comprises a receiving roller and a feeding pipe wound on the receiving roller, one end of the feeding pipe is connected to the curing medium source, and the other end of the feeding pipe is connected to the curing nozzle;

[0014] The adjustment mechanism comprises a control rod, the control rod abuts against the storage mechanism, the control rod blocks the feed pipe when the storage mechanism is stationary, and releases the blockage of the feed pipe when the storage mechanism moves.

[0015] Furthermore, the adjustment mechanism also includes a rotating rod, a rotating wheel and a pull rope;

[0016] The rotating rod is coaxially connected to the rotating wheel, and the rotating wheel abuts against the roller shaft of the storage roller and rotates synchronously when the storage roller rotates;

[0017] Two ends of the pull rope are respectively connected to the rotating rod and the control rod.

[0018] Furthermore, the adjustment mechanism further includes a slider and a return spring;

[0019] The return spring is connected between the rotating rod and the sliding block.

[0020] Furthermore, the adjustment mechanism also includes a spring, and the spring is connected between the slider and the storage mechanism.

[0021] Furthermore, the adjustment mechanism also includes a limit plate and a tension spring, the limit plate is connected to the end of the control rod, and the tension spring is connected between the limit plate and the feed pipe.

[0022] Furthermore, it also includes a supporting mechanism, which includes a rectangular frame, both ends of the rectangular frame are connected to wheel seats, and the wheel seats are rotatably connected to moving wheels.

[0023] Furthermore, it also includes a spraying mechanism, which includes two pulleys that rotate on a fixed axis at both ends of the rectangular frame, a belt is connected between the two pulleys, and the maintenance nozzle is connected to the belt.

[0024] Furthermore, the spraying mechanism also includes a connecting seat, and the maintenance nozzle is rotatably connected to the connecting seat.

[0025] Furthermore, the spraying mechanism also includes two mounting seats, the two mounting seats are respectively connected to the two ends of the rectangular frame, and the two pulleys are respectively rotatably connected to the wheel seats.

[0026] Furthermore, the rectangular frame is connected to a motor for driving the pulley and the roller to rotate.

[0027] The beneficial effects of the present invention are analyzed as follows:

[0028] A large-area concrete curing device comprises a displaceable curing nozzle, a receiving mechanism and an adjusting mechanism; the receiving mechanism comprises a receiving roller and a feed pipe wound on the receiving roller, one end of the feed pipe is connected to a curing medium source, and the other end is connected to the curing nozzle; the adjusting mechanism comprises a control rod, the control rod abuts against the receiving mechanism, the control rod blocks the feed pipe when the receiving mechanism is stationary, and releases the blockage of the feed pipe when the receiving mechanism moves.

[0029] The movement of the maintenance nozzle causes the maintenance medium to be sprayed on the concrete surface. After the maintenance nozzle moves to both ends of the stroke, it moves back. When the maintenance nozzle moves away from the storage roller, the hose on the storage roller is released synchronously. When the maintenance nozzle approaches the storage roller, the hose is stored on the storage roller. At this time, the feed pipe connected to the hose is opened, allowing the maintenance medium to flow in the hose, so that the maintenance medium can be sprayed out from the maintenance nozzle. When the movement of the maintenance nozzle is obstructed, the storage roller stops rotating. At this time, the feed pipe is closed, so that the maintenance medium no longer flows in the hose. At this time, the maintenance medium no longer sprays out from the maintenance nozzle, thereby avoiding the situation where the maintenance medium is sprayed at a fixed position of the concrete when the movement of the maintenance nozzle is obstructed, resulting in uneven spraying and waste of maintenance medium.

[0045] Example

[0046] like Figure 1-Figure 7As shown, a large-area concrete curing device includes a support mechanism 100, a spraying mechanism 200 is connected to the support mechanism 100, the spraying mechanism 200 includes a curing nozzle 250 that reciprocates on the support mechanism 100, an adjusting mechanism 400 is connected to the support mechanism 100, the adjusting mechanism 400 includes a receiving roller 320, the receiving roller 320 is coaxially connected to a feeding pipe 340, a hose 330 that is connected to the feeding pipe 340 is wound around the receiving roller 320, and the curing nozzle 250 is connected to the hose 330; the feeding pipe 340 is connected to a curing medium source, when the curing nozzle 250 moves on the support mechanism 100, the receiving roller 320 rotates synchronously to release or store the hose 330 in the receiving roller 320, and when the receiving roller 320 rotates, the feeding pipe 340 opens.

[0047] The working mechanism of the large-area concrete curing device provided in this embodiment is as follows:

[0048] The support mechanism 100 spans the upper part of the concrete to be cured. When the spraying mechanism 200 is in operation, the curing nozzle 250 reciprocates on the support mechanism 100, so that the curing medium is sprayed on the concrete surface. After the curing nozzle 250 moves to both ends of the stroke, it moves back, and then pushes the support mechanism 100 to move the curing nozzle 250 spraying width, so that the concrete is evenly sprayed. When the curing nozzle 250 moves away from the receiving roller 320, the hose 330 on the receiving roller 320 is released synchronously, and when the curing nozzle 250 approaches the receiving roller 320, the hose 330 is released. The storage roller 320 is stored, and the feed pipe 340 connected to the hose 330 is opened, so that the curing medium can flow in the hose 330, so that the curing medium can be sprayed out from the curing nozzle 250. When the movement of the curing nozzle 250 is blocked, the storage roller 320 stops rotating, and the feed pipe 340 is closed, so that the curing medium no longer flows in the hose 330, and the curing medium no longer sprays out from the curing nozzle 250, thereby avoiding the curing medium being sprayed at a fixed position of the concrete when the movement of the curing nozzle 250 is blocked, resulting in uneven spraying and waste of the curing medium.

[0049] Regarding the structures of the storage mechanism 300 and the adjustment mechanism 400, specifically:

[0050] The control rod 410 is inserted into the feed tube 340, and the control rod 410 can move toward or away from the feed tube 340 to open or close the feed tube 340; the storage mechanism 300 includes a rotating seat 310, and the storage roller 320 rotates on the rotating seat 310. The rotating seat 310 is rotatably connected to a rotating wheel 480, and the rotating wheel 480 is attached to the roller shaft 321 of the storage roller 320; the adjustment mechanism 400 includes a control rod 410, and the end of the control rod 410 is connected to a limiting plate 420, and the limiting plate 420 is connected to the roller shaft 321 of the storage roller 320. A tension spring 430 is connected between the feed pipe 340, a rotating rod 470 is coaxially connected to the rotating wheel 480, a pull rope 490 is connected between the rotating rod 470 and the limiting plate 420, and the pull rope 490 can be wound around the rotating rod 470; the slider 440 slides on the rotating seat 310, and a spring 460 is connected between the slider 440 and the rotating seat 310, and the spring 460 pushes the slider 440 so that the rotating wheel 480 is close to the roller shaft 321; a return spring 450 is connected between the rotating rod 470 and the slider 440.

[0051] The roller shaft 321 is connected to the rotating seat 310 through a torsion spring. When the maintenance nozzle 250 moves away from the receiving roller 320, the maintenance nozzle 250 pulls the receiving roller 320 to rotate through the hose 330. At this time, the roller shaft 321 rotates, so that the friction between the roller shaft 321 and the rotating wheel 480 causes the rotating wheel 480 to rotate. At this time, the rotating wheel 480 drives the rotating rod 470 to rotate. At this time, the rotating rod 470 stores the pull rope 490, so that the pull rope 490 pulls the limit plate 420 to make the control rod 410 Slide in the direction away from the feed pipe 340 but do not disengage, at this time the feed pipe 340 is in a through state, so that the curing medium can flow in the hose 330, and when the curing nozzle 250 moves toward the direction close to the receiving roller 320, the elasticity of the torsion spring is released so that the receiving roller 320 rotates in the opposite direction to receive the hose 330, and at this time the roller shaft 321 drives the rotating wheel 480 to rotate in the opposite direction, and at this time the rotating rod 470 first releases the pull rope 490 and then receives the pull rope 490, so that the feed pipe 340 is first closed and then maintained open;

[0052] The control rod 410 and the feed pipe 340 are limited by a limiting structure to limit the sliding travel of the control rod 410. The limiting structure may be a protrusion provided on the control rod 410 in the feed pipe 340, so that when the control rod 410 is pulled, the protrusion abuts against the inner wall of the feed pipe 340 to ensure that the control rod 410 will not be pulled out of the feed pipe 340, or the tension of the tension spring 430 may be used to prevent the control rod 410 from being separated from the feed pipe 340.

[0053] When the maintenance nozzle 250 stops moving, the storage roller 320 stops rotating, the rotating wheel 480 is no longer driven, and the return spring 450 causes the rotating rod 470 to rotate and reset, and the pulling force of the tension spring 430 causes the pull rope 490 to be released, so that the control rod 410 slides toward the direction of the feeding pipe 340, so that the feeding pipe 340 is closed;

[0054] The spring 460 provides a thrust for the slider 440 , so that the rotating wheel 480 is in close contact with the roller shaft 321 , thereby preventing the transmission from being disconnected due to wear between the two.

[0055] Regarding the structure of the support mechanism 100, specifically:

[0056] The supporting mechanism 100 includes a rectangular frame 110 , both ends of the rectangular frame 110 are connected to wheel seats 120 , and moving wheels 130 are rotatably connected to the wheel seats 120 .

[0057] Regarding the structure of the spraying mechanism 200, specifically:

[0058] The spraying mechanism 200 includes two pulleys 220 that rotate on a fixed axis at both ends of the rectangular frame 110, a belt 230 is connected between the two pulleys 220, and the maintenance nozzle 250 is connected to the belt 230; the spraying mechanism 200 also includes a connecting seat 240, and the maintenance nozzle 250 is rotatably connected to the connecting seat 240; the spraying mechanism 200 also includes two mounting seats 210, the two mounting seats 210 are respectively connected to the two ends of the rectangular frame 110, and the two pulleys 220 are respectively rotatably connected to the wheel seat 120.

[0059] The belt 230 is moved by the rotation of the pulley 220, so that the connection seat 240 moves synchronously with the belt 230. When the belt 230 moves, the maintenance nozzle 250 can be reciprocated in the rectangular frame 110. The maintenance nozzle 250 and the connection seat 240 are rotationally connected to ensure that the hose 330 will not be entangled on the maintenance nozzle 250 due to the movement of the maintenance nozzle 250.

[0060] The rectangular frame 110 spans the concrete to be cured, and the wheel seat 120 is located on both sides of the concrete. The length of the rectangular frame 110 is customized according to the width of the concrete to be cured. When the curing nozzle 250 moves to the end of the stroke, the wheel seat 120 is pushed to make the moving wheel 130 roll, so that the curing nozzle 250 evenly sprays the curing medium on the concrete.

[0061] Among the optional methods of this embodiment, the more preferred ones are:

[0062] The rectangular frame 110 is connected to a motor for driving the pulley 220 and the roller shaft 321 to rotate.

[0063] The output end of the motor can be connected to the pulley 220 separately, so that the roller 321 is pulled by the hose 330 and the restoring force of the torsion spring to reciprocate;

[0064] Alternatively, a motor may be connected to the roller 321 separately, and a sensor for detecting the movement of the belt 230 may be provided in the rectangular frame 110. The sensor controls the start and stop of the motor on the roller 321, so that the maintenance nozzle 250 discharges material when it moves and stops when it stops.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
