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 is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. If the surrounding environment does not have these conditions, artificial curing of concrete is required.

[0003] Concrete curing agent is a coating material that solidifies after being sprayed on the concrete surface to form a dense film that isolates the concrete surface from the air and greatly reduces the evaporation loss of water from the concrete surface. In this way, the water in the concrete itself is used to maximize the hydration process and achieve 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 water outlet pipe with a certain weight to spray the curing agent when in use. If the spraying range is to be changed, the operator needs to hold the water outlet pipe and constantly change the spraying direction of the nozzle, which results in low spraying efficiency and difficulty in spraying evenly.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0021] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and 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.

[0022] like Figures 1 to 3As shown, the present invention provides a concrete curing device, comprising: The walking mechanism 1 can be pushed by a person to walk, or an existing automatic walking mechanism 1 can be used, preferably an automatic walking mechanism 1; A bracket 2, which is arranged at the front end of the walking mechanism 1; Two rotating shafts 3 are parallel to each other and are both horizontally arranged.

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 driving force, and a second gear 302 is arranged on the other rotating shaft 3. Two first rotating rods 4, one first rotating rod 4 is fixedly disposed on each rotating shaft 3, and one spray head is fixedly disposed on each of the two first rotating rods 4; when the two first rotating rods 4 are rotated to be vertical and are located below the corresponding rotating shaft 3, the two spray heads are opposite to the ground and spray downwards; 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 part of the stirring rod located in the mixing box 5 is provided with a stirring blade.

[0023] The concrete curing device provided by the present invention, when in use, causes the walking mechanism 1 to move along the extension direction of the rotating shaft 3. During the walking process, the two first rotating rods 4 and the stirring rod can be rotated synchronously by driving a rotating shaft 3 to rotate by power. The rotation of the two first rotating rods 4 can simultaneously increase the spraying range of the two nozzles, making the spraying efficiency higher, and because the two rotating shafts 3 continuously rotate forward and backward, the spraying can be more uniform. The rotation of the stirring rod can stir the water and curing agent in the mixing box 5 to prevent the precipitation of the curing agent due to lack of stirring during the curing process. The present invention can achieve the effect of spraying the curing agent over a large range while stirring through a driving device 8, which can save costs.

[0024] In another embodiment, in the concrete curing device, each first rotating rod 4 is a telescopic rod, and is formed by a plurality of sleeves which are sequentially sleeved from the inside to the outside. One end of each first rotating rod 4 located in the innermost sleeve is fixedly connected to the corresponding rotating shaft 3, and the other end is inserted into the inner part of the adjacent sleeve. Two nozzles are respectively fixed on the outermost sleeve of the corresponding first rotating rod 4. The first rotating rod 4 is set as a telescopic rod, and the spraying range of the nozzle can be adjusted by extending and contracting the first rotating rod 4, so that the applicability is enhanced.

[0025] In another embodiment, in the concrete curing device, each first rotating rod 4 is formed by two sleeve sections, and at least one slider is provided on the outer wall of the other end of the inner sleeve of the two sleeve sections, 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, and the slide groove does not penetrate the two ends of the outer sleeve, so that the two ends of the outer sleeve can limit the movement of the slider, and when adjusting the length of the first rotating rod 4, the slider and the slide groove cooperate to play a guiding role.

[0026] In another embodiment, in the concrete curing device, Figure 1 As shown, a pushing block 401 is fixedly provided on the outer wall of the sleeve located outside each first rotating rod 4, and a pushing and pulling device is provided on each rotating shaft 3, and the pushing ends of the two pushing and pulling devices are respectively fixedly connected to the corresponding pushing blocks 401; when the two first rotating rods 4 are rotated to vertical, the two pushing and pulling devices can push and pull the corresponding pushing blocks 401 along the vertical direction respectively.

[0027] In another embodiment, in the concrete curing device, the support comprises: A pair of first brackets 21 are opposite to each other and arranged in parallel, and one first bracket 21 corresponds to one rotating shaft 3; the first bracket 21 is inverted U-shaped, one end of the first bracket 21 is fixedly connected to the top of the walking mechanism 1, the top of the first bracket 21 is not opposite to the walking mechanism 1, but opposite to the ground, the two vertical parts of the first bracket 21 are respectively rotatably connected to the corresponding rotating shaft 3, and the two nozzles and the two first rotating rods 4 are respectively opposite to the top of the corresponding first bracket 21; One or two second brackets 22, each second bracket 22 is inverted U-shaped; 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 respectively 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; The concrete curing device also includes: One or two second rotating rods 6, the number of which is equal to that of the second brackets 22 and corresponds 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 respectively fixed on the two rotating shafts 3; Figure 2 As shown, when the first rotating rod 4 rotates to a vertical position, the corresponding second rotating rod 6 also rotates to a vertical position and is located above the corresponding rotating shaft 3; Two or four groups of sensing components, one group of sensing components is respectively arranged at both ends 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, and the sensing components include: The adjusting block 7 is L-shaped, the top of the vertical portion of the adjusting block 7 passes through the first guide groove corresponding thereto, the horizontal portion of the adjusting block 7 is located below the horizontal portion of the second bracket 22 corresponding thereto, and the top of the horizontal portion of the adjusting block 7 is provided with a second guide groove parallel to the first guide groove; A driving device 8, which is fixed on the vertical portion of the second bracket 22, wherein the output end of the driving device 8 is connected to the vertical portion of the adjusting block 7, and the adjusting block 7 moves along the extension direction of the first guide groove under the drive of the driving device 8; The sensing member 9 is arranged in the horizontal part of the second bracket 22 corresponding thereto and fixed at the top of the vertical part of the adjusting block 7; the sensing member 9 is arranged in the horizontal part of the second bracket 22 corresponding thereto, so as to protect the sensing member 9 and prevent the sensing member 9 from being damaged by external force.

[0028] The moving rod 10 is vertically arranged, the top of the moving rod 10 passes through the first guide groove and is inserted into the horizontal part of the second bracket 22, and the bottom is inserted into the second guide groove. The part of the moving rod 10 located in the horizontal part of the second bracket 22 is provided with a trigger rod 12, and the trigger rod 12 is opposite to the induction member 9; The spring 11 is sleeved 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 with 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. A controller is connected to each of the sensing elements 9 .

[0029] By setting the second rotating rod 6 and the sensing component, the forward and reverse rotation range 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 range of the rotating shaft 3 can be changed as needed, thereby changing the spraying range of the nozzle, making it more applicable.

[0030] 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 first preliminarily determined, 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 toward the corresponding sensing member 9 with the trigger rod 12 thereon, and the trigger rod 12 triggers the sensing member 9 and transmits a signal to the controller, and 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 toward the corresponding sensing member 9 with the trigger rod 12 thereon, and the trigger rod 12 triggers the sensing member 9 and transmits a signal to the controller, and 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, they are adjusted by driving the adjusting blocks 7 to move through the driving device 8. When making specific adjustments, such as Figure 3 As 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 driven to move to the left by the driving device 8, and adjusted according to the above method until the required swing amplitude is reached; 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 driven to move to the right by the driving device 8, and adjusted according to the above method until the required swing amplitude is reached. 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 driven to move to the right by the driving device 8, and adjusted according to the above method until the required swing amplitude is reached; 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 driven to move to the left by the driving device 8, and adjusted according to the above method until the required swing amplitude is reached. The left and right swing amplitudes of the first rotating rod 4 can be adjusted separately, which has strong applicability.

[0031] 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 achieving the required rotation amplitude of the other first rotating rod 4.

[0032] 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.

[0033] When only the nozzle on the first rotating rod 4 below the first rotating shaft is required to spray the mixture of curing agent and water, the rotation range of the first rotating shaft can be adjusted to thereby adjust the spraying range of the nozzle. Specifically, when adjusting the forward and reverse rotation range of the first rotating shaft, the two sensing components 9 corresponding to the second rotating rod 6 on the second rotating shaft are closed, and the corresponding two sets of sensing 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 first rotating shaft is driven by power 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 with a moving rod 10, the moving rod 10 moves toward the corresponding sensing element 9 with the trigger rod 12 thereon, and the trigger rod 12 triggers the sensing element 9 and transmits a signal to the controller, and the controller controls the rotating shaft 3 to rotate in the opposite direction. After that, when the second rotating rod 6 on the first rotating shaft rotates to contact with another moving rod 10, the moving rod 10 moves toward the corresponding sensing element 9 with the trigger rod 12 thereon, and the trigger rod 12 triggers the sensing element 9 and transmits a signal to the controller, and 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.

[0034] When only the nozzle on the first rotating rod 4 below the second rotating shaft is required to spray the mixture of curing agent and water, the rotation amplitude of the second rotating shaft can be adjusted, thereby adjusting the spraying range of the nozzle. Specifically, when adjusting the forward and reverse rotation amplitude of the second rotating shaft, the two sensing components 9 corresponding to the second rotating rod 6 on the first rotating shaft are closed, and the corresponding two sets of sensing 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, and adjusted according to the above method.

[0035] When it is required that the nozzles on the first rotating rods 4 under the two rotating shafts 3 all spray the mixed solution of curing agent and water, only the rotation amplitude of the first rotating shaft or the second rotating shaft can be adjusted as needed.

[0036] 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 provided with the second rotating rod 6 is adjusted directly by adjusting the positions of the two adjusting blocks 7, and when the forward and reverse rotation amplitude of the other rotating shaft 3 is adjusted, it is adjusted indirectly by adjusting the positions of the two adjusting blocks 7. When adjusting, considering that the two first rotating rods 4 are always symmetrical, the rotation amplitude of one first rotating rod 4 is adjusted, that is, the rotation amplitude of the other first rotating rod 4 is symmetrically adjusted. When there are two second rotating rods 6, the forward and reverse rotation amplitudes of the two rotating shafts 3 are adjusted separately.

[0037] In another embodiment, in the concrete curing device, the sensing element 9 is a pressure sensor.

[0038] In another embodiment, in the concrete curing device, wheels are provided at the bottom of the moving rod 10, and the wheels are slidably arranged in the second guide groove, so that the moving rod 10 can move more smoothly along the second guide groove. A limit block 101 is provided on the moving 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 moving rod 10 cannot move upward, so that the trigger rod 12 is always opposite to the sensing element 9.

[0039] In another embodiment, in the concrete curing device, there is only one second rotating rod 6. Since the two first rotating rods 4 are symmetrically arranged and the two rotating shafts 3 rotate synchronously, the rotation amplitude of one first rotating rod 4 can be adjusted to adjust the rotation amplitude of the other first rotating rod 4, so there is no need to set four sets of sensing components, but during the adjustment, the rotation amplitude of the first rotating rod 4 to be adjusted should be aimed at reaching the required rotation amplitude.

[0040] 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.

[0041] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and 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 the illustrations shown and described herein.
