Description

Technical Field

[0001] This utility model belongs to the field of concrete curing technology, and in particular relates to a concrete curing device for building engineering. Background Technology

[0002] After the concrete has set, in hot and dry weather, it is necessary to maintain a certain temperature and humidity to ensure the quality of the concrete. Water curing is carried out after the concrete has set. Generally, a water pipe is dragged by hand on the concrete structure surface and workers walk to various parts of the concrete structure to spray water, or a spray truck is used to spray water on the concrete structure surface. However, the spray range cannot be adjusted, so it cannot well meet the curing needs of different concrete components.

[0003] Currently, there are also technologies that use spray devices to cure concrete, such as the concrete curing device disclosed in patent CN219785223U. In this technology, multiple spray components are controlled by telescopic components to change the spacing of the spray components in the direction perpendicular to the travel direction, thereby adjusting the spray range. However, the number of spray components is fixed, and the spray volume within the interval of the spray components remains unchanged. When the spacing of the spray components is adjusted, the actual spray volume cannot simultaneously meet the adjusted spray range. Therefore, after the spacing is increased, in order to avoid spray dead zones between two adjacent spray components, the spray range can only be increased by pressurization. It is not possible to adaptively change the spray range according to the operating width range of the curing device. In actual use, a water pump that can adjust the water pressure is required, which increases the equipment cost and makes the operation more complicated.

[0004] Therefore, we propose a concrete curing device for building engineering to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the actual spray volume is difficult to meet the curing requirements of concrete spraying after adjusting the spray width range, and to propose a concrete curing device for building engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete curing device for building construction includes:

[0008] The frame includes a connecting block, a telescopic main shaft, and two side tie rods. Wheels are rotatably mounted on both ends of the main shaft. The two telescopic ends of the main shaft are rotatably connected to the connecting block via the side tie rods, forming a variable triangular structure. A telescopic adjustment rod is provided between the connecting block and the main shaft.

[0009] A water tank, installed above the main shaft, is used to store water for spraying.

[0010] An equidistant telescopic assembly, wherein both ends of the equidistant telescopic assembly are respectively connected to the two telescopic ends of the main shaft;

[0011] The water supply pipe is connected to the water pump installed in the water tank and is mounted on the equidistant telescopic assembly;

[0012] And multiple spraying components, the spraying range of the spraying components is variable, the multiple spraying components are connected to the water supply pipe and are spaced apart along the length direction of the equidistant telescopic components.

[0013] Preferably, the main shaft includes a mounting tube and two telescopic rods, with the two telescopic rods slidably disposed coaxially at both ends of the mounting tube.

[0014] Preferably, the sidewall of the mounting pipe is provided with a guide groove along the axial direction, and the telescopic rod is provided with a guide block that matches the guide groove.

[0015] Preferably, the equidistant telescopic component includes multiple intersecting and hinged connecting rods, wherein the ends of adjacent connecting rods are hinged to form a scissor linkage structure.

[0016] Preferably, the spray assembly is located at the central hinge point of the connecting rod. The spray assembly includes a shaft tube and an outer tube respectively fixedly mounted on two connecting rods in the same group. The shaft tube passes through the outer tube and is sealed to the outer tube. The bottom of the shaft tube and the outer tube has a nozzle adjustment structure with an adjustable spray range.

[0017] Preferably, the nozzle adjustment structure includes a spray cavity fixedly disposed at the bottom of the shaft tube, a sleeve fixedly installed at the bottom of the outer sleeve, a plurality of spray holes opened on the side of the spray cavity, the coverage range of the plurality of spray holes being 180°, the sleeve having a 180° notch, and the overlap range of the spray holes and the notch changing when the shaft tube and the outer sleeve rotate.

[0018] Preferably, the telescopic adjustment rod includes a threaded rod fixedly mounted on the connecting block, a positioning tube fixedly mounted on the side of the main shaft, a threaded sleeve rotatably connected to the end of the positioning tube, and the threaded rod and the threaded sleeve being threadedly connected and extending into the positioning tube.

[0019] Preferably, a handrail is rotatably mounted on the connecting block, and a directional wheel is fixedly mounted at the bottom end of the handrail.

[0020] This utility model has the following technical effects and advantages:

[0021] When encountering narrow concrete surfaces, the concrete curing device can be retracted to a suitable size using equidistant telescopic components for easy passage. When encountering wide concrete surfaces, the device can be extended to its maximum length using the telescopic components, maximizing the spraying range and improving the curing efficiency of the concrete.

[0022] This concrete curing device, through the setting of a nozzle adjustment structure and the rotation of the connecting rods inside the equidistant telescopic assembly, allows the number of exposed nozzles in the gap to adaptively change as the equidistant telescopic assembly adjusts the spray width. This is achieved through the deflection of the two connecting rods in the same group, which in turn causes the spray range of a single spray assembly to change synchronously. When the spray width increases, the spray range of the spray assembly also automatically increases synchronously, ensuring that under the same output water pressure, the adjustment of the spray width by the equidistant telescopic assembly will not create spray dead zones.

[0031] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0032] Reference Figure 1-4 A concrete curing device for building construction includes a frame 1, a water tank 2, an equidistant telescopic component 3, a water supply pipe 4, and multiple spray components 5. The frame 1 supports the movement of the water tank 2 and the spray components 5. Water is sprayed onto the concrete components that need curing through the spray components 5. As the frame 1 moves, the water is evenly sprayed onto the surface of the components to ensure the moisture content of the concrete components and enable the concrete components to meet the curing standards.

[0033] The frame 1 includes a connecting block 13, a telescopic main shaft 11, and two side tie rods 12. Wheels 16 are rotatably mounted at both ends of the main shaft 11. The distance between the two wheels 16 is equal to the width of the spraying area and can be adjusted according to the width of the concrete component. For components with smaller widths or those located in confined spaces, narrowing the width of the curing device makes operation more flexible. For components with larger widths, widening the width of the curing device improves curing efficiency. The two telescopic ends of the main shaft 11 are rotatably connected to the connecting block 13 via the side tie rods 12, forming a variable triangular structure. A telescopic adjustment rod 14 is provided between the connecting block 13 and the main shaft 11. During use, the state of the triangular structure can be changed by adjusting the length of the telescopic adjustment rod 14, thereby controlling the length of the main shaft 11.

[0034] Reference Figure 1-4 The main shaft 11 includes an installation tube 111 and two telescopic rods 112. The two telescopic rods 112 are coaxially and slidably disposed at both ends of the installation tube 111. The installation tube 111 is located in the center and its position remains unchanged. The length of the main shaft 11 is controlled by the extension and retraction of the two telescopic rods 112. A guide groove is provided on the side wall of the installation tube 111 along the axial direction. A guide block that matches the guide groove is provided on the telescopic rod 112. The guide groove and the guide block cooperate to limit the movement, ensuring the stability of the axial sliding of the telescopic rod 112 and the installation tube 111, while limiting the rotation of the telescopic rod 112, and ensuring the stability of the position of the equidistant telescopic assembly 3 and the spray assembly 5.

[0035] Reference Figure 1-4 The telescopic adjustment rod 14 includes a threaded rod 141 fixedly mounted on the connecting block 13. A positioning tube 142 is fixedly mounted on the side of the main shaft 11. A threaded sleeve 143 is rotatably connected to the end of the positioning tube 142. The threaded rod 141 is threadedly connected to the threaded sleeve 143 and extends into the positioning tube 142. By rotating the threaded sleeve 143, the threaded rod 141 can be driven to move axially under the action of the thread. Since the length of the side tie rod 12 is fixed, when the length of the telescopic adjustment rod 14 changes, the distance between the connection points of the two side tie rods 12 and the main shaft 11 changes. Therefore, the length of the main shaft 11 will also change synchronously, thereby realizing the adjustment of the coverage width of the maintenance device.

[0036] A handlebar 15 is rotatably mounted on the connecting block 13, and a directional wheel 151 is fixedly mounted at the bottom of the handlebar 15. The handlebar 15 is used to control the movement of the maintenance device and adjust the movement direction of the maintenance device. The directional wheel 151 and the two wheels 16 cooperate to form a three-wheel structure, making the movement of the frame 1 more flexible.

[0037] Water tank 2 is installed above main shaft 11. Water tank 2 is equipped with a water pump for storing spray water and pressurizing and transporting the water.

[0038] The two ends of the equidistant telescopic component 3 are respectively connected to the two telescopic ends of the main shaft 11, so the telescopic component 3 and the main shaft 11 keep synchronized in telescopic movement.

[0039] The water supply pipe 4 is connected to the water pump installed in the water tank 2 and is mounted on the equidistant telescopic component 3.

[0040] The spraying range of the spraying component 5 is variable. Multiple spraying components 5 are connected to the water supply pipe 4 and are spaced apart along the length of the equidistant telescopic component 3. After controlling the width of the maintenance device, the equidistant telescopic component 3 changes its length synchronously. Multiple spraying components 5 located on the equidistant telescopic component 3 change their positions at equal intervals to ensure consistent spraying intervals and uniform spraying. The water supply pipe 4 is a flexible hose that can adapt to the extension and change between two spraying components 5. The longest extension distance between two spraying components 5 is less than the length of the water supply pipe 4 between the two spraying components 5.

[0041] The equidistant telescopic assembly 3 includes multiple intersecting and hinged connecting rods 31, wherein the ends of adjacent connecting rods 31 are hinged to form a scissor linkage structure. Through the scissor linkage structure, the hinge points between each group of connecting rods 31 are kept at equal intervals during the telescopic process.

[0042] Reference Figure 4-7 The spray assembly 5 is located at the central hinge point of the connecting rod 31. Therefore, when the length of the equidistant telescopic assembly 3 changes, the interval distance of the multiple spray assemblies 5 is consistent. The spray assembly 5 includes a shaft tube 51 and an outer sleeve 52, which are respectively fixed on two connecting rods 31 in the same group (the shaft tube 51 is fixed to the upper connecting rod 31, and the outer sleeve 52 is fixed to the lower connecting rod 31). The shaft tube 51 passes through the outer sleeve 52 and is sealed to the outer sleeve 52. The length change of the equidistant telescopic assembly 3 is achieved by the change of the included angle of the connecting rods 31 in the same group. Therefore, when the length of the equidistant telescopic assembly 3 changes, the two connecting rods 31 in the same group will rotate symmetrically relative to each other, causing the shaft tube 51 and the outer sleeve 52 to rotate relative to each other. There is a nozzle adjustment structure at the bottom of the shaft tube 51 and the outer sleeve 52 with an adjustable spray range. When the shaft tube 51 and the outer sleeve 52 rotate relative to each other, the spray range is changed.

[0043] Specifically, refer to Figure 4-7 The nozzle adjustment structure includes a spray cavity 511 fixedly mounted at the bottom of the shaft tube 51, and a sealing sleeve 521 fixedly mounted at the bottom of the outer sleeve 52. The shaft tube 51 and the outer sleeve 52 serve as a hinged pivot for two connecting rods 31. The spray cavity 511 rotates with the shaft tube 51, and the sealing sleeve 521 rotates with the outer sleeve 52. The side of the spray cavity 511 has multiple spray holes 512, and the coverage area of ​​the multiple spray holes 512 is 180°. The sealing sleeve 521 has a 180° notch 522. When the shaft tube 51 and the outer sleeve tube 52 rotate, the overlap range of the nozzle 512 and the notch 522 changes. The coverage range of the nozzle 512 and the range of the notch 522 are symmetrical along the forward direction of the maintenance device. When the overlap range changes, the number of nozzles 512 exposed also changes. The greater the elongation of the equidistant telescopic component 3, the more nozzles 512 are exposed and the larger the spraying range. The smaller the elongation of the equidistant telescopic component 3, the fewer nozzles 512 are exposed and the smaller the spraying range.

[0044] The working principle of this utility model is as follows:

[0045] In use, the distance between the two wheels 16 is adjusted according to the concrete components to be cured. Specifically, by rotating the threaded sleeve 143, the threaded rod 141 can be driven to move axially under the action of the thread. Since the length of the side tie rod 12 is fixed, when the length of the telescopic adjustment rod 14 changes, the distance between the connection points of the two side tie rods 12 and the main shaft 11 changes, so the length of the main shaft 11 will also change synchronously, realizing the adjustment of the coverage width of the curing device. The equidistant telescopic component 3 changes synchronously with the length of the main shaft 11, and the connecting rods 31 in the same group will rotate relative to each other. The shaft tube 51 and the outer sleeve 52 serve as the hinge pivot of the two connecting rods 31. The spray chamber 511 rotates with the shaft tube 51, and the sleeve 521 rotates with the outer sleeve 52. When the shaft tube 51 and the outer sleeve 52 rotate, the overlap range of the spray hole 512 and the notch 522 changes. The coverage range of the spray hole 512 and the range of the notch 522 are symmetrical along the forward direction of the maintenance device. When the overlap range changes, the number of exposed spray holes 512 also changes. The greater the elongation of the equidistant telescopic component 3, the more exposed spray holes 512 are and the larger the spray range. The smaller the elongation of the equidistant telescopic component 3, the fewer exposed spray holes 512 are and the smaller the spray range. This achieves adaptive change of the spray range with the width adjustment of the maintenance device.
