Description

Technical Field

[0001] The utility model relates to the field of concrete curing, in particular to a spray curing device for prefabricated concrete parts. Background Art

[0002] After production and processing, precast concrete parts need to be sprayed and cured for a period of time. This helps keep the concrete surface moist, avoid cracks, and improve the strength and service life of the precast parts.

[0003] A common type of precast concrete part is a rectangular columnar precast concrete part. In the prior art, vertical spray curing is generally used for such relatively long precast concrete parts. For relevant solutions, please refer to the descriptions of patents such as CN202311867464.8 and CN202011378371.5. The main measure is to place the columnar precast concrete part vertically, and then use an annular water spray device to cover the columnar precast concrete part and move it up and down for spray curing.

[0004] This method has the following disadvantages: 1. When the columnar concrete precast parts are placed vertically, the upper and lower ends lack effective fixation, which makes them prone to tipping over and causing safety accidents; 2. During vertical spray maintenance, the sprayed water falls directly to the ground for discharge, resulting in a large amount of water resource waste, so improvements are needed. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the first purpose of the utility model is to provide a concrete precast part spray curing device to solve the problem of greater danger and waste of water resources when the existing device is spraying and curing columnar concrete precast parts.

[0006] The technical solution of the utility model is as follows: A spray curing device for precast concrete parts, characterized in that it comprises:

[0007] A rotating frame module, wherein the rotating frame modules are two and are arranged oppositely, one on the left and the other on the right, each rotating frame module comprises a base, a first driving mechanism, a bracket, a second driving mechanism and a clamping plate, the bracket is rotatably arranged on the base, the first driving mechanism is connected to the bracket to drive the bracket to rotate, the rotation axis of the bracket extends horizontally, two clamping plates arranged oppositely are arranged on the bracket, the second driving mechanism is connected to the two clamping plates to drive the two clamping plates to move toward or away from each other, wherein the relative arrangement direction of the two clamping plates of the left rotating frame module is perpendicular to the relative arrangement direction of the two clamping plates of the right rotating frame module;

[0008] The spray module comprises a spray head and a water collecting tank. The upper side of the water collecting tank is open. The water collecting tank is arranged between two rotating frame modules. A plurality of spray heads are arranged above the water collecting tank.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] 1. This device adopts a horizontal placement method to place the columnar concrete prefabricated parts, which is relatively safe. In addition, the relative arrangement direction of the two clamping plates of the left rotating frame module is perpendicular to the relative arrangement direction of the two clamping plates of the right rotating frame module, so that multiple sides of the columnar concrete prefabricated parts can be clamped at one time. In this way, when the two brackets rotate to drive the columnar concrete prefabricated parts to rotate, the columnar concrete prefabricated parts are not easy to fall off, ensuring the safety of the spraying operation and maintenance;

[0011] 2. The spraying method uses a nozzle that does not move, and the precast concrete parts rotate 360 ​​degrees around the horizontal axis for spraying and curing. This way, the spraying is more uniform and the curing effect is good. The flowing spray water can be collected by the water collection tank below, which is convenient for later reuse and can reduce the waste of water resources.

[0026] In the description of the present utility model, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0027] like Figure 1-Figure 4The concrete precast component spraying and curing device shown comprises: a rotating frame module 1 and a spraying module 2.

[0028] like Figure 1-Figure 2 As shown, there are two rotating frame modules 1, one on the left and the other on the right, and each rotating frame module 1 includes a base 11, a first driving mechanism, a bracket 12, a second driving mechanism and a clamping plate 13. The bracket 12 is rotatably arranged on the base 11. The first driving mechanism is connected to the bracket 12 to drive the bracket 12 to rotate. The rotation axis of the bracket 12 extends horizontally. Two clamping plates 13 arranged opposite to each other are provided on the bracket 12. The second driving mechanism is connected to the two clamping plates 13 to drive the two clamping plates 13 to move toward or away from each other.

[0029] The relative arrangement direction of the two clamping plates 13 of the left rotating frame module 1 is perpendicular to the relative arrangement direction of the two clamping plates 13 of the right rotating frame module 1. Figure 1 Taking the perspective shown as an example, the relative arrangement direction of the two clamping plates 13 of the left rotating rack module 1 is the front-to-back direction, and the relative arrangement direction of the two clamping plates 13 of the right rotating rack module 1 is the up-down direction.

[0030] Therefore, when the two rotating frame modules 1 clamp a conventional rectangular columnar concrete precast part, the four sides of the columnar concrete precast part, namely the front, back, upper and lower sides, will be clamped and fixed by different clamping plates 13, so that when the two brackets 12 rotate to drive the columnar concrete precast part to rotate, the columnar concrete precast part is not likely to fall off, thereby ensuring the safety during spraying operation and maintenance.

[0031] In a further configuration, in order to ensure the clamping effect of the clamping plates 13 and prevent the precast concrete parts from falling, the clamping surface of each clamping plate 13 may be provided with an anti-slip pad.

[0032] like Figure 3 and Figure 4 As shown, the bracket 12 is provided with a first rotating shaft, the base 11 is provided with a first rotating hole, the first rotating shaft is rotatably arranged in the first rotating hole, and the first driving mechanism includes a first motor 14, the first motor 14 is fixed on the base 11 and connected to the first rotating shaft, thereby the first motor 14 can drive the bracket 12 to rotate 360 ​​degrees around the horizontal axis.

[0033] The second driving mechanism includes a second motor 15 and a second screw 16. A bearing seat 17 is provided on the bracket 12. The axial ends of the second screw 16 are rotatably arranged in the bearing seat 17. The second motor 15 is fixedly arranged on the bracket 12 and connected to the second screw 16. The second screw 16 is divided into two rod sections along its length direction. The threads on each rod section have opposite rotation directions. The two clamping plates 13 are provided with screw holes. The two rod sections are threadedly matched with the two clamping plates 13 in a one-to-one correspondence. Since the second screw 16 is provided with two sections of threads with opposite rotation directions, when the second motor 15 drives the second screw 16 to rotate, the relative movement of the two clamping plates 13 on the second screw 16 can be achieved. This driving form is simple and easy to achieve. In addition, the threaded connection has self-locking properties. After the clamping plates 13 clamp the concrete precast parts, they are not easy to loosen.

[0034] like Figure 3 As shown, the spray module 2 includes a nozzle 21 and a water collecting tank 22. The upper side of the water collecting tank 22 is open. The water collecting tank 22 is arranged between the two rotating frame modules 1. A plurality of nozzles 21 are arranged above the water collecting tank 22. The nozzles 21 are used to connect to an external water supply system to spray water to the clamped precast concrete parts. The water flowing down from the precast concrete parts can be collected in the water collecting tank 22 below, which is convenient for later reuse and can reduce the waste of water resources.

[0035] In order to ensure that the water from the nozzle 21 can be sprayed onto the prefabricated concrete parts more fully, Figure 2 As shown, a crossbeam 23 is connected between the two bases 11, and the crossbeam 23 is located between the water collecting tank 22 and the bracket 12. A plurality of nozzles 21 extending in the left and right directions are provided on the crossbeam 23. In this case, the nozzle 21 adopts a spraying method of spraying water upward to the precast concrete parts, which can make the overall structure of the device more compact.

[0036] In order to reduce the use of related water supply pipelines, such as Figure 3 and Figure 4 As shown, the crossbeam 23 is a hollow tube and is connected to the nozzle 21 . A water inlet pipe 24 is provided at one end of the crossbeam 23 . The water inlet pipe 24 is connected to an external water supply system so that water can be supplied to the nozzle 21 through the crossbeam 23 .

[0037] The specific use process of this device is as follows:

[0038] First, a conventional rectangular columnar concrete precast part is hoisted between two rotating frame modules 1 by a crane, and then the two clamping plates 13 of each rotating frame module 1 are driven by a second driving mechanism to move toward each other to clamp the columnar concrete precast part. Since the relative arrangement directions of the two clamping plates 13 of the left and right rotating frame modules 1 are vertical, when the clamping operation is completed, the four sides of the rectangular columnar concrete precast part will be in a clamped state.

[0039] Then the crane is removed, the nozzle 21 and the first driving mechanism are turned on, and the first driving mechanism drives the bracket 12 to rotate 360 ​​degrees around the horizontal axis, thereby driving the clamped precast concrete part to rotate 360 ​​degrees. After the water sprayed by the nozzle 21 falls on the precast concrete part, the precast concrete part can be sprayed and maintained more evenly, and the spray water flowing down can be collected by the water collection tank 22 below, avoiding the waste of water resources.

[0040] In summary, this device has the following characteristics:

[0041] 1. The device adopts a horizontal placement method to place the columnar concrete precast parts, which is relatively safe. In addition, the relative arrangement direction of the two clamping plates 13 of the left rotating frame module 1 is perpendicular to the relative arrangement direction of the two clamping plates 13 of the right rotating frame module 1, so that multiple sides of the columnar concrete precast parts can be clamped at one time. In this way, when the two brackets 12 rotate to drive the columnar concrete precast parts to rotate, the columnar concrete precast parts are not likely to fall off, ensuring the safety of the spraying operation and maintenance;

[0042] 2. The spraying method adopts that the nozzle 21 is stationary, and the precast concrete parts rotate 360 ​​degrees around the horizontal axis for spraying and curing. In this way, the spraying is more uniform and the curing effect is good. In addition, the spraying water flowing down can be collected by the water collection tank 22 below, which is convenient for later reuse and can reduce the waste of water resources.

[0043] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
