Description

Technical Field

[0001] The present invention relates to the field of concrete construction, and more particularly to a concrete curing device. Background Art

[0002] Concrete curing involves artificially creating certain humidity and temperature conditions to allow freshly poured concrete to harden normally or accelerate its strength growth. The gradual hardening and strength growth of concrete is the result of cement hydration, which requires certain temperature and humidity conditions. If these conditions are not met, manual curing is required.

[0003] Concrete curing agent is a coating material that solidifies after being sprayed on the concrete surface, forming a dense film that isolates the concrete surface from the air and significantly reduces water loss from evaporation. This maximizes hydration by utilizing the concrete's own moisture, achieving the purpose of curing.

[0004] Existing concrete curing devices, such as the one disclosed in application publication number CN 107791372 A, require an operator to hold a weighted water outlet pipe to spray the curing agent. To change the spraying range, the operator must hold the water outlet pipe and constantly change the spraying direction of the nozzle, resulting in low spraying efficiency and difficulty in spraying evenly. Summary of the Invention

The rotation of the two first rotating rods can simultaneously increase the spraying range of the two nozzles, making the spraying efficiency higher.

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0040] It should be noted that, in the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] like Figures 1 to 3 As shown, the present invention provides a concrete curing device, comprising:

[0042] The walking mechanism 1 can be pushed by a person or an existing automatic walking mechanism 1 can be used, preferably an automatic walking mechanism 1;

[0043] A bracket 2 is provided at the front end of the walking mechanism 1;

[0044] Two rotating shafts 3 are parallel to each other and are both arranged horizontally. A first gear 301 is respectively mounted on and fixed to the two rotating shafts 3. The two first gears 301 are engaged with each other so that the two rotating shafts 3 can rotate synchronously. Both ends of the two rotating shafts 3 are rotatably connected to the bracket. One of the two rotating shafts 3 rotates forward and reverse under the power, and the other rotating shaft 3 is provided with a second gear 302;

[0045] Two first rotating rods 4, one first rotating rod 4 is fixedly mounted on each rotating shaft 3, and each first rotating rod 4 is fixedly mounted with a spray head; when both first rotating rods 4 are rotated to a vertical position and are located below their corresponding rotating shafts 3, both spray heads face the ground and spray downwards;

[0046] The mixing box 5 is provided with an inlet for the curing agent, an inlet for water and an outlet for the mixed liquid. The outlet for the mixed liquid is connected to the nozzle. The stirring rod of the mixing box 5 is vertically arranged, and the top of the stirring rod extends out of the top of the mixing box 5. A third gear meshing with the second gear 302 is provided on it. The part of the stirring rod located in the mixing box 5 is provided with a stirring blade.

[0047] The concrete curing device provided by this solution, when in use, causes the traveling mechanism 1 to travel along the extension direction of the rotating shaft 3. During travel, the two first rotating rods 4 and the stirring rod can be rotated synchronously by driving one rotating shaft 3 with power. The rotation of the two first rotating rods 4 can simultaneously increase the spraying range of the two nozzles, making the spraying more efficient. Moreover, the continuous forward and reverse rotation of the two rotating shafts 3 can achieve more uniform spraying. The rotation of the stirring rod can stir the water and curing agent in the mixing box 5, preventing the curing agent from settling due to lack of stirring during the curing process. The present invention can achieve the effect of spraying the curing agent over a large area while stirring through a single driving device 8, which can save costs.

[0048] In another embodiment, each first rotating rod 4 in the concrete curing device is a telescopic rod and is formed by a plurality of sleeves that are sequentially sleeved from the inside out. One end of the innermost sleeve of each first rotating rod 4 is fixedly connected to the corresponding rotating shaft 3, and the other end is inserted into the interior of the adjacent sleeve. The two nozzles are respectively fixed to the outermost sleeve of the corresponding first rotating rod 4. The telescopic first rotating rod 4 allows the spraying range of the nozzle to be adjusted by extending and retracting the first rotating rod 4, thereby enhancing applicability.

[0049] In another embodiment, in the concrete curing device, each first rotating rod 4 is composed of two sleeves, and at least one slider is provided on the outer wall of the other end of the inner sleeve of the two sleeves, and at least one slide groove is provided on the inner wall of the outer sleeve along its length direction. One slider corresponds to one slide groove, and each slider is slidably arranged in the corresponding slide groove. The slide groove does not pass through the two ends of the outer sleeve, so that the two ends of the outer sleeve can limit the movement of the slider. When adjusting the length of the first rotating rod 4, the slider and the slide groove cooperate to play a guiding role.

[0050] In another embodiment, in the concrete curing device, Figure 1 As shown, each first rotating rod 4 is fixedly provided with a pushing block 401 on the outer wall of the sleeve located on the outside, and each rotating shaft 3 is provided with a pushing and pulling device, and the pushing ends of the two pushing and pulling devices are respectively fixedly connected to the pushing blocks 401 corresponding to them; when the two first rotating rods 4 are rotated to vertical, the two pushing and pulling devices can respectively push and pull the pushing blocks 401 corresponding to them in the vertical direction.

[0051] In another embodiment, in the concrete curing device, the bracket includes:

[0052] A pair of first brackets 21 are opposite and arranged in parallel, with each first bracket 21 corresponding to one rotating shaft 3. The first bracket 21 is in an inverted U shape, with one end of the first bracket 21 fixedly connected to the top of the traveling mechanism 1. The top of the first bracket 21 is not opposite to the traveling mechanism 1, but opposite to the ground. The two vertical portions of the first bracket 21 are respectively rotatably connected to the corresponding rotating shaft 3. The two nozzles and the two first rotating rods 4 are respectively opposite to the top of the corresponding first bracket 21.

[0053] One or two second brackets 22, each second bracket 22 is an inverted U-shape; when there is one second bracket 22, the top of the second bracket 22 is fixedly connected to the top of one of the two first brackets 21; when there are two second brackets 22, the tops of the two second brackets 22 are respectively fixedly connected to the tops of a pair of first brackets 21, and the two second brackets 22 are staggered so as not to interfere with each other; the connecting line of the two vertical parts of each second bracket 22 is perpendicular to the connecting line of the two vertical parts of the corresponding first bracket 21; the interior of the horizontal part of each second bracket 22 is hollow, and the bottom of the two ends of the horizontal part of each second bracket 22 is respectively provided with a first guide groove along its length direction;

[0054] The concrete curing device further comprises:

[0055] One or two second rotating rods 6, which are equal to the number of the second brackets 22 and correspond one to one; when there is one second rotating rod 6, the second rotating rod 6 is fixed on the rotating shaft 3 corresponding to the second bracket 22, and when there are two second rotating rods 6, the two second rotating rods 6 are fixed on the two rotating shafts 3 respectively; Figure 2 As shown, when the first rotating rod 4 is rotated to vertical, the corresponding second rotating rod 6 is also rotated to vertical and is located above the corresponding rotating shaft 3;

[0056] Two or four groups of sensing components, one group of sensing components is provided at each end of the horizontal portion of each second bracket 22, and the upper portion of each second rotating rod 6 is located between the two corresponding groups of sensing components, the sensing components including:

[0057] The adjusting block 7 is L-shaped, with the top of the vertical portion of the adjusting block 7 passing through the corresponding first guide slot, the horizontal portion of the adjusting block 7 being located below the horizontal portion of the corresponding second bracket 22, and the top of the horizontal portion of the adjusting block 7 being provided with a second guide slot parallel to the first guide slot;

[0058] A driving device 8 is fixed to the vertical portion of the second bracket 22, and an output end of the driving device 8 is connected to the vertical portion of the adjustment block 7. The adjustment block 7 moves along the extension direction of the first guide groove under the drive of the driving device 8;

[0059] The sensing member 9 is arranged in the horizontal part of the corresponding second bracket 22 and fixed to the top of the vertical part of the adjustment block 7; setting the sensing member 9 in the horizontal part of the corresponding second bracket 22 can protect the sensing member 9 and prevent the sensing member 9 from being damaged by external force.

[0060] The movable rod 10 is vertically arranged, with the top of the movable rod 10 passing through the first guide slot and inserted into the horizontal portion of the second bracket 22, and the bottom of the movable rod 10 inserted into the second guide slot. The portion of the movable rod 10 located in the horizontal portion of the second bracket 22 is provided with a trigger rod 12, and the trigger rod 12 is opposite to the sensing member 9;

[0061] The spring 11 is mounted on the trigger rod 12 and is located between the moving rod 10 and the sensing element 9. When the spring 11 is in a natural state, the moving rod 10 and the sensing element 9 are separated by a certain distance. When the second rotating rod 6 rotates along the rotating shaft 3 until it collides with the moving rod 10, the spring 11 is compressed, the trigger rod 12 triggers the sensing element 9, and the rotating shaft 3 rotates in the opposite direction.

[0062] The controller is connected to each of the sensing elements 9 .

[0063] By setting up the second rotating rod 6 and the sensing component, the forward and reverse rotation amplitude of the rotating shaft 3 can be limited, and the sensing component can move relative to the horizontal part of the second bracket 22. Therefore, the forward and reverse rotation amplitude of the rotating shaft 3 can be changed as needed, thereby changing the spraying range of the nozzle, making it more applicable.

[0064] When there is only one second rotating rod 6, there are two groups of sensing components. When adjusting the forward and reverse rotation amplitude of the rotating shaft 3 provided with the second rotating rod 6, the positions of the two adjusting blocks 7 are preliminarily determined first, and then the power is used to drive one rotating shaft 3 to rotate, so that the two first rotating rods 4, the stirring rod and the second rotating rod 6 can be rotated synchronously. When the second rotating rod 6 rotates to contact with a moving rod 10, the moving rod 10 moves with the trigger rod 12 thereon toward the corresponding sensing part 9. The trigger rod 12 triggers the sensing part 9 and transmits the signal to the controller. The controller controls the rotating shaft 3 to rotate in the opposite direction. After that, when the second rotating rod 6 rotates to contact with another moving rod 10, the moving rod 10 moves with the trigger rod 12 thereon toward the corresponding sensing part 9. The trigger rod 12 triggers the sensing part 9 and transmits the signal to the controller. The controller controls the rotating shaft 3 to rotate in the opposite direction. If the positions of the two preliminarily determined adjusting blocks 7 need to be adjusted, the adjusting blocks 7 are driven to move by the driving device 8 for adjustment. When making specific adjustments, such as Figure 3As shown, if you want to increase the swing amplitude of the first rotating rod 4 from the vertical direction to the right, the adjustment block 7 on the left side is moved to the left by the driving device 8 and adjusted according to the above method until the desired swing amplitude is achieved. If you want to increase the swing amplitude of the first rotating rod 4 from the vertical direction to the left, the adjustment block 7 on the right side is moved to the right by the driving device 8 and adjusted according to the above method until the desired swing amplitude is achieved. If you want to reduce the swing amplitude of the first rotating rod 4 from the vertical direction to the right, the adjustment block 7 on the left side is moved to the right by the driving device 8 and adjusted according to the above method until the desired swing amplitude is achieved. If you want to reduce the swing amplitude of the first rotating rod 4 from the vertical direction to the left, the adjustment block 7 on the right side is moved to the left by the driving device 8 and adjusted according to the above method until the desired swing amplitude is achieved. The left and right swing amplitudes of the first rotating rod 4 can be adjusted separately, which is highly applicable.

[0065] Because the two first rotating rods 4 are symmetrically arranged, when the forward and reverse rotation amplitude of the rotating shaft 3 provided with the second rotating rod 6 is adjusted, the rotation amplitude of the other first rotating rod 4 is also adjusted. Therefore, when the rotation amplitude of the other first rotating rod 4 needs to be adjusted, it can be adjusted according to the above method, except that the movement of the adjustment block 7 is aimed at ensuring that the rotation amplitude of the other first rotating rod 4 reaches the required requirement.

[0066] When there are two second rotating rods 6, there are four sets of sensing components. The rotating shaft 3 is composed of a first rotating shaft and a second rotating shaft.

[0067] If only the nozzle on the first rotating rod 4 below the first rotating shaft is required to spray the curing agent and water mixture, the rotation range of the first rotating shaft can be adjusted to adjust the spray range of the nozzle. Specifically, when adjusting the forward and reverse rotation range of the first rotating shaft, the two sensors 9 corresponding to the second rotating rod 6 on the second rotating shaft are turned off, and the corresponding two sets of sensor components are moved to a position where they do not interfere with the rotation of the second rotating rod 6 on the second rotating shaft. Then, the positions of the two adjustment blocks 7 corresponding to the second rotating rod 6 above the first rotating shaft are preliminarily determined, and then the power is used to drive the first rotating shaft to rotate, so that the two first rotating rods 4, the stirring rod and the two second rotating rods 6 can rotate synchronously. When the second rotating rod 6 on the first rotating shaft rotates to contact a moving rod 10, the moving rod 10 brings the trigger rod 12 thereon to move toward the corresponding sensing member 9. The trigger rod 12 triggers the sensing member 9 and transmits a signal to the controller. The controller controls the rotating shaft 3 to rotate in the opposite direction. Afterwards, when the second rotating rod 6 on the first rotating shaft rotates to contact another moving rod 10, the moving rod 10 brings the trigger rod 12 thereon to move toward the corresponding sensing member 9. The trigger rod 12 triggers the sensing member 9 and transmits a signal to the controller. The controller controls the rotating shaft 3 to rotate in the opposite direction. If the positions of the two adjustment blocks 7 preliminarily determined need to be adjusted, the adjustment blocks 7 are driven to move by the driving device 8 to adjust. The specific adjustment method is the same as above.

[0068] If only the nozzle on the first rotating rod 4 below the second rotating shaft is required to spray the curing agent and water mixture, the rotation range of the second rotating shaft can be adjusted to adjust the spray range of the nozzle. Specifically, when adjusting the forward and reverse rotation range of the second rotating shaft, the two sensors 9 corresponding to the second rotating rod 6 on the first rotating shaft are turned off, and the corresponding two sets of sensor components are moved to a position where they do not interfere with the rotation of the second rotating rod 6 on the first rotating shaft. Adjustment is then carried out as described above.

[0069] When it is required that the nozzles on the first rotating rods 4 below the two rotating shafts 3 all spray the mixture of curing agent and water, the rotation amplitude of only the first rotating shaft or the second rotating shaft can be adjusted as needed.

[0070] As can be seen from the above, when there is only one second rotating rod 6, the forward and reverse rotation amplitude of the rotating shaft 3 on which the second rotating rod 6 is provided is adjusted directly by adjusting the positions of the two adjustment blocks 7. When adjusting the forward and reverse rotation amplitude of the other rotating shaft 3, it is adjusted indirectly by adjusting the positions of the two adjustment blocks 7. During adjustment, considering the constant symmetry of the two first rotating rods 4, adjusting the rotation amplitude of one first rotating rod 4 symmetrically adjusts the rotation amplitude of the other first rotating rod 4. When there are two second rotating rods 6, the forward and reverse rotation amplitudes of the two rotating shafts 3 are adjusted separately.

[0071] In another embodiment, in the concrete curing device, the sensing element 9 is a pressure sensor.

[0072] In another embodiment, in the concrete curing device, wheels are provided at the bottom of the movable rod 10, and the wheels are slidably arranged in the second guide groove, so that the movable rod 10 moves more smoothly along the second guide groove. A limit block 101 is provided on the movable rod 10, and the limit block 101 is in contact with the bottom surface of the horizontal part of the second bracket 22, so that the movable rod 10 cannot move upward, so that the trigger rod 12 is always opposite to the sensing member 9.

[0073] In another embodiment, the concrete curing device includes a single second rotating rod 6. Because the two first rotating rods 4 are symmetrically arranged and the two rotating shafts 3 rotate synchronously, adjusting the rotation amplitude of one first rotating rod 4 can adjust the rotation amplitude of the other first rotating rod 4. This eliminates the need for four sets of sensing components. However, during adjustment, the rotation amplitude of the first rotating rod 4 to be adjusted must reach the desired rotation amplitude.

[0074] In another embodiment, in the concrete curing device, the center of the top of each second bracket 22 is fixedly connected to the top of the corresponding first bracket 21.

[0075] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
