Description

Technical Field

[0001] The utility model relates to the field of concrete curing, and particularly to a spray curing device for precast concrete T-shaped beams. Background Art

[0002] In concrete projects, precast concrete T-shaped beams have a wide range of applications. Although the precast concrete T-shaped beams have been formed, the hydration reaction of the cement paste continues. This process requires moisture. If the moisture is insufficient, the hydration reaction will slow down or even stop, which will affect the final strength and durability of the precast concrete T-shaped beams. In addition, the concrete will undergo volume shrinkage during the drying process. If the shrinkage is too severe, cracks may occur, affecting the structural integrity of the concrete. Spraying water for curing can slow down the drying speed, reduce the degree of shrinkage, and control the temperature gradient, reducing the risk of thermal cracking.

[0003] After retrieval, in the prior art, a Chinese patent with the patent application number CN 205189416 U discloses a concrete curing spray device, which includes a mobile positioning frame, a pressure pump and a spray device arranged on the mobile positioning frame. The pressure pump is arranged at the bottom of the mobile positioning frame, and a solenoid valve is installed at the water inlet of the pressure pump. The spray device includes a conduit connecting the water outlet of the pressure pump and a rotating spray head arranged on the mobile positioning frame. The rotating spray head is communicated with the conduit, but there are still the following defects:

[0004] (1) In the above patent document, the spray head is arranged at a fixed position of the device. When adjusting the spraying direction over a large range, the entire device needs to be moved, which limits the spraying position and makes the adjustment process cumbersome, reducing the curing efficiency and quality.

[0005] In the above patent document, the horizontal height of the spray head is fixed, and it is impossible to perform directional spray curing on concrete T-shaped beams of different heights.

[0006] Therefore, we make improvements and propose a spray curing device for precast concrete T-shaped beams. Summary of the Utility Model

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0031] As Figure 1 、 Figure 2 and Figure 4 shown, this embodiment provides a precast concrete T-shaped beam spray curing device, which includes a box body 1, a water inlet valve 11 fixedly connected to the top wall of the box body 1, and an air inlet valve 12 fixedly connected to the top wall of the box body 1. It further includes:

[0032] A steering component, fixedly connected to the top wall of the box body 1, for adjusting the spray direction. Among them, the steering component includes a tooth ring 31 opened on the top wall of the box body 1, a mounting seat 3 rotatably connected to the top wall of the tooth ring 31, a steering motor 32 fixedly connected to the inner wall of the mounting seat 3, and a gear 33 fixedly connected to the output end of the steering motor 32. The gear 33 meshes with the tooth ring 31, and the mounting seat 3 is in communication with the inside of the box body 1;

[0033] A water supply component, fixedly connected to the inner wall of the mounting seat 3, for outputting a spray solution;

[0034] A lifting component, rotatably connected to the top wall of the mounting seat 3, for adjusting the spray height;

[0035] An extension component, slidably connected to the inner wall of the lifting component, for expanding the spray range;

[0036] A traveling component, fixedly connected to the outer wall of the box body 1, for the rapid movement of the device;

[0037] By directly controlling the steering motor 32 to drive the gear 33 to rotate, due to the meshing relationship between the gear 33 and the tooth ring 31, the tooth ring 31 generates a reaction force on the steering motor 32 and the mounting seat 3, causing the mounting seat 3 to rotate relative to the box body 1, so that the sprinkler head 6 can adjust the horizontal direction arbitrarily without being restricted by the device itself.

[0038] As Figure 2 and Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the water supply component includes a support frame 4 fixedly connected to the inner wall of the mounting base 3, a water pump 42 fixedly connected to the inner wall of the support frame 4, a water suction pipe 41 fixedly connected to the bottom wall of the water pump 42, and a water supply pipe 43 fixedly connected to the top wall of the water pump 42. The water supply pipe 43 extends outward through the top wall of the mounting base 3. When the water pump 42 is started, the water pump 42 pumps the liquid inside the box body 1 into the water supply pipe 43 through the water suction pipe 41, and then is transported to the nozzle 6 through the water supply pipe 43 and the drainage hose 54 for spraying, completing the spraying and maintenance of the target.

[0039] As Figure 2 and Figure 3 shown, as a preferred embodiment, on the basis of the above method, further, the lifting component includes a lifting frame 5 rotatably connected to the top wall of the mounting base 3 and a first hydraulic cylinder 51 rotatably connected to the top wall of the mounting base 3. The first hydraulic cylinders 51 are symmetrically distributed about the central axis of the mounting base 3. The first hydraulic cylinder 51 drives the lifting frame 5 to rotate. When spraying and maintaining targets at different heights, the first hydraulic cylinder 51 is started to drive the lifting frame 5 to rotate to a set angle, so that the vertical position of the nozzle 6 is lifted, completing the spraying and maintenance of targets at different heights.

[0040] As Figure 2 , Figure 3 and Figure 5 shown, as a preferred embodiment, on the basis of the above method, further, the extension component includes a first telescopic frame 52 slidably connected to the inner wall of the lifting frame 5, a second telescopic frame 53 slidably connected to the inner wall of the first telescopic frame 52, a drainage hose 54 fixedly connected to the inner wall of the second telescopic frame 53, a second hydraulic cylinder 55 fixedly connected to the top wall of the lifting frame 5, a hydraulic rod 62 rotatably connected to the outer wall of the second telescopic frame 53, a nozzle 6 rotatably connected to the outer wall of the second telescopic frame 53, and a linkage rod 61 fixedly connected to the outer wall of the nozzle 6. The water supply pipe 43 is connected to the nozzle 6 through the drainage hose 54. The second hydraulic cylinder 55 pushes the first telescopic frame 52 and the second telescopic frame 53 to slide and extend. When performing a large-range spraying and maintenance operation, the second hydraulic cylinder 55 is started to drive the first telescopic frame 52 and the second telescopic frame 53 to slide along the inner wall of the lifting frame 5, increasing the spraying height and spraying range of the nozzle 6 and improving the efficiency of spraying and maintenance.

[0041] As Figure 1 shown, as a preferred embodiment, on the basis of the above method, further, the traveling component includes a protection plate 2 fixedly connected to the side wall of the box body 1 and a traveling track 21 fixedly connected to the side wall of the box body 1. The protection plate 2 and the traveling track 21 are symmetrically distributed about the central axis of the box body 1. The position of the device is quickly transferred by controlling the traveling track 21.

[0042] Specifically, when this device is in use: Open the water inlet valve 11 to input the water or solution needed for spraying the target into the box body 1, completing the preparatory work before the spraying and curing operation. Start the water pump 42. The water pump 42 pumps the liquid inside the box body 1 into the water supply pipe 43 through the water suction pipe 41, and then it is transported to the nozzle 6 through the water supply pipe 43 and the drainage hose 54 for spraying, completing the spraying and curing of the target. By directly controlling the steering motor 32 to drive the gear 33 to rotate, due to the meshing relationship between the gear 33 and the gear ring 31, the gear ring 31 generates a reaction force on the steering motor 32 and the mounting seat 3, causing the mounting seat 3 to rotate relative to the box body 1, enabling the nozzle 6 to be adjusted horizontally arbitrarily without being restricted by the device itself. When spraying and curing targets at different heights are needed, start the first hydraulic cylinder 51 to drive the lifting frame 5 to rotate to a set angle, raising the vertical position of the nozzle 6 to complete the spraying and curing of targets at different heights. When large-scale spraying and curing work is needed, start the second hydraulic cylinder 55 to drive the first telescopic frame 52 and the second telescopic frame 53 to slide along the inner wall of the lifting frame 5, increasing the spraying height and spraying range of the nozzle 6 and improving the efficiency of spraying and curing. During spraying, the spraying angle of the nozzle 6 in the vertical direction can be adjusted by controlling the hydraulic rod 62 to drive the linkage rod 61 to rotate, and at the same time, the position of the device can be quickly transferred by controlling the traveling track 21.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiment is a preferred implementation scheme of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
