Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a silo outer wall spraying device and a construction method. Background Art

[0002] In existing technology, silos are cylindrical above-ground structures used to store materials, and can be constructed of concrete or steel. In industry, they can store coke, minerals, cement, and other materials; in agriculture, they can be used to store grain. Concrete silos require a coating on their exterior walls, primarily to protect the concrete while also achieving aesthetic appeal. Typically, multiple silos form a silo complex. The conventional method for painting silo exteriors involves manual painting using a lifting basket. The basket's operating range is small compared to the radius of the exterior of the arc-shaped building, resulting in low construction efficiency. Manual painting can be difficult to achieve uniform quality, impacting exterior appearance. Outdoor painting operations can be highly polluting, with paint drifting uncontrollably in the wind and affecting the health of the painters. Technical issues include low efficiency in manual painting of silo exteriors, difficulty in achieving uniform quality, and paint splashes that not only pollute the environment but also impact the health of the workers.

[0031] The embodiments described below with reference to the accompanying drawings are illustrative and intended only to explain the present invention and are not to be construed as limiting the present invention. In describing the present invention, it should be understood that terms such as "install," "connect," and "fix" are to be understood broadly, encompassing both direct and indirect connection, installation, or fixation, and the present invention is not intended to limit these terms.

[0032] like Figures 1 to 6 The figure shows a schematic diagram of an embodiment of a silo outer wall spraying device according to the present invention. The device comprises a spraying execution unit, which includes a spraying mechanism 3 and a waste collection mechanism 4 connected to the spraying mechanism 3; an operating positioning unit 2, which includes an operating guide rail 23 disposed outside the silo 5, with the spraying mechanism 3 slidably connected to the operating guide rail 23; and a lifting unit 1, which includes an adjustment mechanism and a traction member 13. The adjustment mechanism is connected to the top of the silo 5, and the ends of the traction member 13 are respectively connected to the adjustment mechanism and the operating guide rail 23. The adjustment mechanism is used to control the retraction and extension of the traction member 13 to adjust the height of the operating guide rail 23. Preferably, the adjustment mechanism comprises a support frame 11 fixed to the top of the silo 5 and a winch 12 connected to the support frame 11. The traction member 13 is a steel wire, one end of which is connected to the winch 12 and the other end to the operating guide rail 23. The steel wire can be retracted and extended by rotating the wire drum of the winch 12 to adjust the suspension height of the operating guide rail 23. The operating guide rail 23 is a closed ring that is mounted outside the silo 5.

[0033] In this embodiment, the traction member has a length mark 14. This embodiment can better facilitate construction workers to lift and lower the running guide rail 23, improve the adjustment accuracy, and ensure the spraying effect of the outer wall of the silo 5.

[0034] In this embodiment, the waste collection mechanism 4 includes a housing 41 and a waste collector connected to the housing 41. The housing 41 is connected to the spraying mechanism 3 to collect paint splashes. Preferably, the waste collection mechanism 4 also includes a waste collection pipe 42, which connects the waste collector and the housing 41. The housing 41 can seal the periphery of the spraying mechanism 3, reducing environmental pollution.

[0035] In this embodiment, waste collection mechanism 4 also includes a paint baffle 43, which is connected to housing 41. Housing 41 is an oblique flow collection structure, and paint baffle 43 is used to block paint spray, preventing paint splashing and environmental pollution. The connection between paint baffle 43 and housing 41 forms a closed diversion system that effectively collects splashed paint.

[0036] In this embodiment, the operation and positioning unit 2 further includes a blocking mechanism, which includes a drive assembly 21 and a blocking member 22. The drive assembly 21 is connected to the operation guide rail 23, and the output end of the drive assembly 21 is connected to the blocking member 22. The blocking member 22 is used to switch the operation state of the spraying mechanism 3. Preferably, the drive assembly 21 includes a cylinder mounted on the operation guide rail 23, and the output end of the cylinder is connected to the blocking member 22 to control the movement of the blocking member 22. The blocking member 22 is slidably connected to the operation guide rail 23. The blocking member 22 can block the movement of the spraying mechanism 3 and can also be controlled to lift up to release it.

[0037] In this embodiment, the spraying mechanism 3 includes a moving assembly 31, a accumulator 33, a nozzle 34, and a feed pipe 35. The input end of the feed pipe 35 is located at the top of the silo 5, and the output end of the feed pipe 35 is located at a preset stop position of the running guide rail 23. The accumulator 33 has a material injection port 331. The nozzle 34 is connected to the accumulator 33. The accumulator 33 is slidably connected to the running guide rail 23 via the moving assembly 31. When the accumulator 33 moves to the preset stop position, the material injection port 331 can be aligned with the output end of the feed pipe 35. Preferably, the feed pipe 35 includes a transmission hose and an alignment hard pipe. The alignment hard pipe is installed at the preset stop position of the running guide rail 23. The transmission hose is connected to the alignment hard pipe, and the end of the transmission hose away from the alignment hard pipe is located at the top of the silo 5. When the spraying mechanism 3 moves to the preset stop position, the material injection port 331 of the accumulator 33 can be aligned with the alignment hard pipe. In this embodiment, the personnel only need to be located at the top of the silo 5 to carry out automatic spraying and material replenishment, thereby ensuring construction safety.

[0038] In this embodiment, a power supply unit is also included, and the power supply unit includes a busbar 24 laid on the running guide rail 23. The spraying mechanism also includes a power assembly for driving the moving assembly, and the power assembly is in sliding contact with the busbar 24. The power assembly includes a motor and a current collector 32. The output end of the motor is connected to the moving assembly, and the current collector 32 is electrically connected to the motor. The current collector 32 contacts and cooperates with the busbar 24 to obtain electricity. The moving assembly includes a moving wheel driven by the motor, and the moving wheel is slidably arranged on the running guide rail 23, and the moving wheel is connected to the storage container 33. Preferably, a multifunctional transmission cable 6 is also included. The multifunctional transmission cable 6 includes an electric cable electrically connected to the busbar 24 and an air pipe connected to the driving assembly 21. Preferably, the air pipe is used to connect to the cylinder. The air pipe, the electric cable and the feed pipe 35 are bundled together to form a whole. The input end is located at the top of the silo 5, and the output end is located at a preset stop position of the running guide rail 23.

[0039] The running rail 23 is a closed annular I-shaped cross-section that can be installed outside the silo 5. The running rail 23 can be made of an I-beam. The moving assembly 31 includes multiple moving wheels connected to the accumulator 33. The multiple moving wheels are respectively installed on both sides of the I-beam web. The blocking member 22 is an inverted U-shaped member. The cylinder can drive the blocking member 22 to rise and fall. The blocking member 22 can be inserted from the upper edge of the I-beam to the sides of the web to block the movement of the moving wheels. When the blocking member 22 is raised, the spray mechanism 3 is released to continue spraying. The busbar 24 is connected to the bottom of the lower edge of the I-beam.

[0040] On the other hand, the present invention also provides a construction method of a silo outer wall spraying device, comprising the following steps:

[0041] The height of the running guide rail 23 is adjusted by retracting and extending the traction member through the adjustment mechanism. The spraying mechanism 3 can move along the running guide rail 23 to spray the silo 5. The waste collection mechanism 4 is used to collect splashed paint generated during the spraying process.

[0042] The working process of this embodiment is as follows:

[0043] On the top of the completed silo 5, multiple lifting units 1 are evenly spaced, preferably four lifting units 1 are arranged, and an annular running guide rail 23 adapted to the outer wall of the silo 5 is selected and connected to the corresponding traction member 13, and a spray execution unit is hung on the running guide rail 23.

[0044] The winch 12 drives the traction member 13 to be retracted and extended, moving the running guide rail 23 to the target height. The spraying mechanism 3 is activated and moved along the running guide rail 23 to spray the outer wall of the silo 5. The splashed paint is drained by the paint baffle 43 to the cover 41 and recovered through the waste collection pipe 42 to the waste collector for unified treatment to avoid environmental pollution.

[0045] When the spray mechanism 3 reaches a preset stop position, the drive assembly 21 controls the blocking member 22 to descend, blocking the spray mechanism 3. The lifting unit 1 then controls the running rail 23 to rise or descend, allowing the coating to be applied to adjacent positions. The travel distance can be precisely controlled by the length markings on the traction member 13. Construction workers simultaneously use the feed pipe 35 to inject paint from the injection port 331 of the accumulator 33. Once the paint is replenished and the height of the running rail 23 is adjusted, the drive assembly 21 controls the blocking member 22 to rise, allowing the next round of coating to proceed. In this embodiment, the preset stop position is one, meaning that the spray mechanism 3 pauses after one full round of travel. This continues until the entire outer wall of the silo 5 is sprayed.

[0046] This embodiment can realize the automatic coating of the outer wall of the silo 5, replacing the construction method of high-altitude manual coating using a hanging basket, and through the waste collection mechanism 4, a closed protection can be formed on the periphery of the nozzle 34 during the spraying process and splashed materials can be collected, which can improve construction efficiency, avoid the impact of differences in construction techniques on appearance quality, solve the problem of paint affecting health during manual coating, and reduce the impact of paint splashing on the surrounding environment, thereby realizing fast, safe and environmentally friendly silo outer wall spraying construction.

[0047] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
