Description

Technical Field

[0001] This utility model relates to the field of precast slab production technology, and in particular to a precast concrete slab spraying device. Background Technology

[0002] Precast slabs are floor slabs used in early construction. They are modules or panels used in engineering projects. Precast slabs are precast concrete components that are manufactured and processed in a prefabrication plant and then transported directly to the construction site for installation. That's why they are called precast slabs. Precast slabs have many uses in construction, such as cement slabs covering ditches along roadsides and cement slabs used as insulation layers on roofs.

[0003] In the production of precast concrete slabs, concrete needs to be poured into the mold. After pouring, the concrete needs to be allowed to solidify and take shape. During the forming process, the concrete is prone to drying too quickly, which may cause cracking and affect the strength and durability of the precast slab.

[0004] Therefore, after concrete is poured, it is necessary to keep the concrete moist by spraying water to prevent it from drying out too quickly during the setting process. However, at present, water is mostly sprayed on concrete test blocks manually to ensure their humidity, which is labor-intensive and has low efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the current method of spraying water on concrete test blocks to ensure their humidity is mostly done manually, which is labor-intensive and has low efficiency. Therefore, a concrete precast slab spraying device is proposed.

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

[0010] For water delivery, preferably, a water pump is fixedly connected to the top of the water tank, and an inlet pipe and a hose are fixedly connected to the input and output ends of the water pump, respectively. The inlet pipe extends into the bottom of the water tank, and a delivery pipe is fixedly connected to the hose. The nozzle is fixedly connected below the delivery pipe, and a water inlet is provided on the top of the water tank.

[0011] To drive the nozzle to oscillate, a roller is rotatably mounted on the slider via a rotating shaft. The roller is rotatably connected to the fixed base. A crank is fixedly connected to the rotating shaft. A sliding block is rotatably mounted on the crank. A connecting plate is rotatably mounted on the slider via a transmission shaft.

[0023] Example:

[0024] Reference Figures 1-4 This utility model provides a concrete precast slab spraying device, including a base frame 1 and a water tank 4 fixedly installed on the top of the base frame 1. The water tank 4 is equipped with spray nozzles 5, the number of which is 5-9, preferably 7, and they are equidistantly arranged in the horizontal direction. It also includes a support rod 301, which is horizontally fixedly connected to the base frame 1. A sliding seat 302 is slidably installed on the support rod 301, and a fixed seat 201 is fixedly connected to the sliding seat 302 via a bracket 303. The base frame 1 is equipped with... A drive unit that drives the fixed base 201 to move laterally; a slider 202 that is laterally slidably mounted on the fixed base 201, the movement direction of the slider 202 being perpendicular to the movement direction of the fixed base 201, wherein the nozzle 5 is connected to the slider 202, the fixed base 201 is provided with a moving part that drives the slider 202 to slide, the bottom of the base frame 1 is provided with a caster wheel 17, a handle 18 is fixedly connected to the base frame 1, and an anti-slip sleeve 19 is fitted on the handle 18, the caster wheel 17 and the handle 18 are used to move the device.

[0025] During operation, the drive unit drives the fixed base 201 to move horizontally, and the fixed base 201 drives the nozzle 5 to move synchronously, moving the nozzle 5 to the top of the mold. Then, the nozzle 5 sprays water into the concrete inside the mold. The connecting part drives the slider 202 and the nozzle 5 to move laterally, performing mobile spraying, which replaces the manual watering method and improves the efficiency of the spraying work.

[0026] The drive unit includes a cylinder 304 fixedly connected to the top of the base frame 1. The fixed seat 201 is fixedly connected to the telescopic end of the cylinder 304. The moving unit includes a motor 203 fixedly connected to the outside of the fixed seat 201. The output end of the motor 203 is fixedly connected to a lead screw 204. The lead screw 204 and the cylinder 304 are both horizontally arranged and perpendicular to each other. The lead screw 204 is rotatably connected to the fixed seat 201 through a bearing. The slider 202 is threadedly connected to the lead screw 204. The top of the water tank 4 is fixedly connected to a water pump 6. The input end and output end of the water pump 6 are respectively fixedly connected to a water inlet pipe 7 and a hose 8. The hose 8 is long enough to allow the nozzle 5 to move. The water inlet pipe 7 extends into the bottom of the water tank 4. A delivery pipe 9 is fixedly connected to the hose 8. The nozzle 5 is fixedly connected below the delivery pipe 9. The top of the water tank 4 is provided with a water inlet 10.

[0027] During operation, the cylinder 304 is activated, and its telescopic end extends, causing the fixed base 201 to move outward. The fixed base 201 then moves the nozzle 5 away from the base frame 1, positioning the nozzle 5 directly above the mold. During this process, the fixed base 201, through the bracket 303, causes the sliding seat 302 to slide laterally along the support rod 301. The support rod 301 provides auxiliary support for the fixed base 201 and the nozzle 5, improving stability. Next, the water pump 6 is activated, and the water in the water tank 4 passes through the inlet pipe 7, the hose 8, and the delivery pipe 9 in sequence, finally being sprayed onto the concrete inside the mold by the nozzle 5. Simultaneously, the motor 203 is activated, and its output end drives the lead screw 204 to rotate. The lead screw 204 drives the slider 202 to slide laterally along the fixed base 201, and the slider 202 drives the nozzle 5 to move laterally for spraying.

[0028] A roller 12 is rotatably mounted on the slider 202 via a rotating shaft 11. The roller 12 is in rolling connection with the fixed seat 201. A crank 13 is fixedly connected to the rotating shaft 11. A sliding block 14 is rotatably mounted on the crank 13. A connecting plate 16 is rotatably mounted on the slider 202 via a transmission shaft 15. The transmission shaft 15 is fixedly connected to the conveying pipe 9. The sliding block 14 is in sliding connection with the connecting plate 16.

[0029] During operation, when the slider 202 slides along the fixed base 201, it drives the roller 12 to roll on the fixed base 201 via the rotating shaft 11. This causes the crank 13 to rotate continuously. The crank 13 drives the sliding block 14 to slide on the connecting plate 16, causing the connecting plate 16 to swing. The connecting plate 16 drives the conveying pipe 9 to swing via the transmission shaft 15. The conveying pipe 9 drives the nozzle 5 to swing, continuously changing the spraying angle of the nozzle 5, expanding the spraying range, making the spraying more uniform, and improving the spraying effect.

[0030] In use, this precast concrete slab spraying device is moved near the mold using the casters 17 and handle 18. The cylinder 304 is then activated, and the extension end of the cylinder 304 moves the fixed seat 201 outward. The fixed seat 201 moves the nozzle 5 away from the base frame 1, and the nozzle 5 is moved directly above the mold. During this process, the fixed seat 201 drives the sliding seat 302 to slide laterally along the support rod 301 through the bracket 303. The support rod 301 is used to provide auxiliary support for the fixed seat 201 and the nozzle 5 to improve stability. Then, the water pump 6 is activated, and the water in the water tank 4 passes through the inlet pipe 7, the hose 8, and the delivery pipe 9 in sequence, and is finally sprayed onto the concrete inside the mold by the nozzle 5.

[0031] Simultaneously, the motor 203 is started, and its output end drives the lead screw 204 to rotate. The lead screw 204 drives the slider 202 to slide laterally along the fixed seat 201. The slider 202 drives the nozzle 5 to move laterally for spraying. The slider 202 drives the roller 12 to roll on the fixed seat 201 through the rotating shaft 11, which in turn causes the crank 13 to rotate continuously. The crank 13 drives the sliding block 14 to slide on the connecting plate 16, causing the connecting plate 16 to swing. The connecting plate 16 drives the delivery pipe 9 to swing through the transmission shaft 15. The delivery pipe 9 drives the nozzle 5 to swing, continuously changing the spraying angle of the nozzle 5, expanding the spraying range, making the spraying more uniform, and improving the spraying effect.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
