Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a coating device for building concrete. Background Technology

[0002] In the field of building construction, the surface coating of concrete structures is a key process to ensure the durability, aesthetics and functionality of buildings. Its core requirement is to improve the anti-aging and anti-corrosion capabilities of concrete components by applying protective materials (such as anti-corrosion coatings, anti-seepage coatings, decorative coatings, etc.), extend the service life of buildings, and meet the appearance or functional requirements in specific scenarios.

[0003] However, the applicant believes that the shortcomings are as follows: 1. Traditional coating operations mostly rely on manual hand tools. When operating manually, the coating area is small and the speed is slow, which increases the time cost of operation and the overall efficiency is low; 2. Some existing coating equipment lacks a dedicated material mixing mechanism. The material needs to be mixed in an external container in advance and then poured into the coating device manually. If the operation time is long, the material is prone to sedimentation in the device, resulting in uneven composition of the coating layer.

[0004] To address these issues, we propose a coating device for building concrete. Utility Model Content

[0005] The purpose of this invention is to provide a coating device for building concrete to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating device for building concrete, comprising a device base, with movable wheels installed at the four corners of the lower surface of the device base; a main frame vertically fixed to the upper surface of the device base; a protective shell installed on the upper surface of the device base and inside the main frame; a threaded rod installed on the upper surface of the device base and inside the main frame; two sets of transmission gears arranged inside the protective shell; a transmission motor installed on the upper surface of the device base and at the rear of the main frame; a coating hopper connected to the threaded rod via a nut seat; two sets of guide rods arranged on the upper surface of the device base and inside the main frame; the guide rods connected to the coating hopper via guide blocks; an equipment bracket fixedly connected to the rear end of the upper surface of the device base; a mixing tank installed on one side of the upper end of the equipment bracket; a conveying pump installed on the other side; a bucket lid installed on the upper end of the mixing tank; a stirring motor fixedly installed on the upper end of the bucket lid; the output end of the stirring motor extending into the mixing tank and fixedly connected to a stirring rod; and a handrail fixedly connected to the rear of the upper end of the equipment bracket.

[0007] Preferably, both the main frame and the protective shell are configured as box structures with an open bottom and a hollow interior. The front surface of the main frame has three sets of parallel sliding grooves in the vertical direction. These three sets of vertical sliding grooves on the front surface of the main frame provide a stable channel for the lifting and connection of the coating hopper.

[0008] Preferably, the bottom end of the threaded rod is rotatably connected to the upper surface of the device base, and the top end is rotatably connected to the upper end of the inner wall of the main frame. The surface of the threaded rod is threaded with a nut seat, and the front end of the nut seat passes through the sliding groove in the middle of the front surface of the main frame and is fixedly connected to the middle of the rear end of the coating hopper. The two ends of the threaded rod are rotatably connected to the device base and the inner wall of the main frame, respectively, to ensure rotational stability. The nut seat passes through the groove to connect to the coating hopper, so that the rotation of the threaded rod drives the coating hopper to accurately lift and lower, meeting the coating needs of different heights.

[0009] Preferably, one set of transmission gears is fixedly sleeved on the lower outer side of the threaded rod, and the other set of transmission gears is fixedly connected to the output end of the transmission motor. The two sets of transmission gears mesh with each other, and the two sets of transmission gears are respectively sleeved on the threaded rod and connected to the transmission motor and mesh with each other, so as to transmit the motor power and drive the threaded rod to rotate stably.

[0010] Preferably, a nut seat is threaded onto the outer side of the threaded rod, and two sets of guide rods are symmetrically distributed on the left and right sides of the threaded rod. Each set of guide rods is movably fitted with a guide block. The nut seat and the two sets of guide blocks pass through the corresponding sliding grooves on the front surface of the main frame. The front end of the nut seat is fixedly connected to the middle position of the rear end of the coating hopper, and the front ends of the two sets of guide blocks are fixedly connected to the left and right sides of the rear end of the coating hopper. The two sets of guide rods are symmetrically distributed on both sides of the threaded rod. The guide blocks are fitted onto the guide rods and connected to the coating hopper, which can limit the rotational offset of the coating hopper during lifting and lowering, and achieve smooth lifting and lowering in conjunction with the nut seat.

[0011] Preferably, the coating hopper has an open bucket shape that is wider at the top and slightly narrower at the bottom, with a certain extension structure at the front end. The open bucket shape makes it easy to receive and transport the coating material and prevents it from overflowing. The extension structure at the front end can fit against the wall surface.

[0012] Preferably, the input end of the delivery pump is connected to the bottom of the mixing tank through a pipe, and the output end extends through the main frame to the top of the coating hopper through a pipe. The input end of the delivery pump is connected to the bottom of the mixing tank, and the output end is connected to the top of the coating hopper, which can stably deliver the uniformly mixed coating material to the hopper and realize the automation of material supply.

[0013] This utility model provides a coating device for building concrete, which has the following beneficial effects:

[0014] By using a threaded rod, a drive motor, and a coating hopper in combination, manual labor is reduced, the coating area per application is increased, the coating speed is accelerated, the operation time is shortened, and the overall coating efficiency is effectively improved.

[0015] By using a mixing tank and a delivery pump together, this coating device is equipped with a dedicated material mixing mechanism. There is no need to mix materials in an external container, reducing manual material feeding. The material can be mixed in real time directly inside the device. Relying on the device's built-in mixing function, even if the operation time is long, it can ensure that the material is always in a uniform state, effectively reducing material sedimentation in the device and improving the consistency of the coating composition.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, this embodiment proposes a coating device for building concrete, including a device base 1. Four casters 2 are installed at the four corners of the lower surface of the device base 1. A main frame 3 is vertically fixed to the upper surface of the device base 1. A protective shell 4 is installed on the upper surface of the device base 1 and inside the main frame 3. A threaded rod 5 is installed on the upper surface of the device base 1 and inside the main frame 3. Two sets of transmission gears 6 are arranged inside the protective shell 4. A transmission motor 7 is installed on the upper surface of the device base 1 and at the rear of the main frame 3. The coating material is connected to the threaded rod 5 through a nut seat 8. Two sets of guide rods 10 are installed on the upper surface of the device base 1 and inside the main frame 3. The guide rods 10 are connected to the coating hopper 9 through guide blocks 11. An equipment bracket 12 is fixedly connected to the rear end of the upper surface of the device base 1. A mixing tank 13 is installed on one side of the upper end of the equipment bracket 12, and a conveying pump 17 is installed on the other side. A tank cover 14 is installed on the upper end of the mixing tank 13. A stirring motor 15 is fixedly installed on the upper end of the tank cover 14. The output end of the stirring motor 15 extends into the mixing tank 13 and is fixedly connected to a stirring rod 16. A handrail 1 is fixedly connected to the rear side of the upper end of the equipment bracket 12. 8; Both the main frame 3 and the protective shell 4 are box structures with an open bottom and a hollow interior. The front surface of the main frame 3 has three sets of parallel sliding grooves along the vertical direction. The bottom end of the threaded rod 5 is rotatably connected to the upper surface of the device base 1, and the top end is rotatably connected to the upper end of the inner wall of the main frame 3. The surface of the threaded rod 5 is threaded with a nut seat 8, and the front end of the nut seat 8 passes through the sliding groove in the middle of the front surface of the main frame 3 and is fixedly connected to the middle of the rear end of the coating hopper 9. One set of transmission gears 6 is fixedly sleeved on the lower outer side of the threaded rod 5, and the other set of transmission gears 6 is connected to the output end of the transmission motor 7. The two sets of transmission gears 6 are fixedly connected and mesh with each other. The threaded rod 5 is threaded with a nut seat 8 on the outside. The two sets of guide rods 10 are symmetrically distributed on the left and right sides of the threaded rod 5. Each set of guide rods 10 is movably fitted with a guide block 11 on the outside. The nut seat 8 and the two sets of guide blocks 11 pass through the corresponding sliding grooves on the front surface of the main frame 3. The front end of the nut seat 8 is fixedly connected to the middle position of the rear end of the coating hopper 9. The front ends of the two sets of guide blocks 11 are fixedly connected to the left and right sides of the rear end of the coating hopper 9. The coating hopper 9 has an open bucket shape with a wider top and a slightly narrower bottom, and a certain extension structure at the front end.

[0027] In the above embodiment, the operator holds the handle 18 at the upper end of the equipment support 12 and pushes the device to the concrete area to be coated via the moving wheels 2. The distance between the device and the wall is adjusted according to the coating position, keeping the front extension structure of the coating hopper 9 in contact with the wall. The device power is turned on, and the delivery pump 17 is started to continuously deliver coating into the coating hopper 9, maintaining a stable coating level. Simultaneously, the drive motor 7 is started to control the coating hopper 9 to slowly rise along the wall at an appropriate speed. With the front extension structure of the hopper in contact with the wall, and because the coating hopper 9 is inclined, the coating will be evenly applied to the concrete surface. The coating width is determined by the extension structure of the hopper. To ensure coverage and avoid missed areas, once the coating hopper 9 reaches its maximum working height, turn off the drive motor 7 to stop lifting. Move the device horizontally along the wall for one coating width, ensuring no gaps or overlaps with the previous coating area, or allowing a small overlap as required by the construction. Then, start the drive motor 7 in reverse to control the coating hopper 9 to slowly descend and coat the next area. Repeat the above process until the entire concrete wall is coated. If a higher coating thickness is required, the second and third coats can be applied after the first coat has dried, following the same procedure. Ensure each coat is applied evenly and the thickness meets the design standards.

[0028] Example 2

[0029] like Figure 5 and Figure 6 As shown, based on the same concept as the above embodiments, this embodiment also proposes that: the input end of the delivery pump 17 is connected to the bottom of the mixing tank 13 through a pipe, and the output end extends through the main frame 3 to the top of the coating hopper 9 through a pipe.

[0030] In the above embodiment, open the lid 14 of the mixing tank 13, pour the calculated proportion of coating material and additives into the mixing tank 13, close the lid 14 of the mixing tank 13 tightly, turn on the power of the mixing motor 15, start the motor switch, adjust the motor speed to a suitable level, and stir the material in the mixing tank 13 evenly to start the coating operation. After the coating operation is completed, first turn off the switches of the mixing motor 15 and the drive motor 7 to stop the stirring and lifting functions; then turn off the switch of the delivery pump 17, cut off the main power of the equipment, disassemble the connecting pipes between the delivery pump 17 and the mixing tank 13 and the coating hopper 9, rinse the inner wall of the pipes with a special solvent to ensure that there is no paint residue, and clean the inside of the coating hopper 9 to prevent the paint from drying and affecting the next use.
