Description

Technical Field

[0001] This utility model relates to the field of tower crane structural component coating technology, and more specifically, to an intelligent production line for tower crane structural component coating. Background Technology

[0002] Tower cranes, also known as tower hoisting machines, are a type of lifting equipment widely used in construction. Tower crane structural components are the various parts that make up the overall structure of a tower crane, mainly including the tower body, jib, counterweight jib, tower cap, slewing bearing, and base. A tower crane structural component coating production line refers to an automated or semi-automated production system consisting of a series of equipment and processes for surface coating of tower crane structural components. This system automates or semi-automates the coating process, reduces manual operation time and labor intensity, and enables rapid and continuous coating of tower crane structural components, greatly improving production efficiency and meeting the needs of large-scale production.

[0003] In existing coating production lines, a powder spraying chamber is typically installed to coat the tower crane. However, it is inconvenient to change the powder concentration inside the spraying chamber. When the powder concentration is too high, it can create a flammable and explosive environment inside the spraying chamber, posing a serious safety hazard. If the powder concentration is too low, it will result in uneven coating thickness, failing to meet the protection and appearance requirements of the tower crane's structural components. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an intelligent production line for coating tower crane structural components, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent production line for coating tower crane structural components, comprising an accumulation chain, on which are sequentially arranged an loading station, a shot blasting chamber, a pretreatment chamber, a water blowing chamber, a moisture drying chamber, a pure water unit, a zinc spraying chamber, a powder spraying chamber, an infrared preheating chamber, a curing chamber, a forced cooling chamber, a central control room, and an unloading station. A storage bin is movably installed in the powder spraying chamber. Connecting plates are fixedly connected to the bottom of the storage bin near both side edges, and the bottom ends of both connecting plates are fixedly connected to the powder spraying chamber. An output pump is fixedly installed at the center of the bottom of the storage bin. A material guiding assembly is provided on the output pump. The material guiding assembly includes a rigid pipe, a flexible hose, a discharge hopper, a self-locking motor, two rotating shafts, a flow meter, an air pipe, a blower, and a valve. The top and bottom ends of the rigid pipe are fixedly connected to the output pump and the flexible hose, respectively. The bottom end of the flexible hose is fixedly connected to the discharge hopper. A dust concentration sensor is installed inside the powder spraying chamber.

[0006] Furthermore, one end of each of the two rotating shafts facing each other is fixedly connected to the discharge hopper, and the other end of one of the rotating shafts is fixedly connected to a self-locking motor.

[0007] As can be seen, in the above technical solution, the self-locking motor is started, and the operation of the self-locking motor drives the two rotating shafts to rotate, thereby driving the discharge hopper to rotate, and the angle of the discharge hopper can be adjusted according to the needs.

[0008] Furthermore, the flow meter is fixedly mounted on the hose.

[0009] It can be seen that the above technical solution is designed to facilitate the monitoring of powder output.

[0010] Furthermore, the exhaust fan is fixedly installed on one side of one of the connecting plates, and both ends of the air pipe are fixedly connected to the exhaust fan and the rigid pipe, respectively. The valve is fixedly installed on the air pipe.

[0011] Furthermore, the dust concentration sensor is equipped with a moving component, which includes a stepper motor, a lead screw, a slider, a slide bar, and two vertical plates. The dust concentration sensor is fixedly installed at the bottom end of the slider, and the stepper motor is fixedly installed at the rear side of the powder spraying chamber, with the output shaft end of the stepper motor fixedly connected to the lead screw.

[0012] Furthermore, one end of both the lead screw and the slide rod passes through the slider. The lead screw is movably connected to the accumulation chain via a bearing, and the slide rod is fixedly connected to the powder spraying chamber. The top ends of both vertical plates are fixedly connected to the slider. One of the vertical plates is fixedly connected to the self-locking motor, and the other vertical plate is movably connected to another rotating shaft via a bearing.

[0013] Furthermore, the front side of the powder spraying chamber is movably connected to a door via a latch.

[0014] It can be seen that the above technical solution facilitates the cleaning of powder in the powder spraying chamber.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model sprays powder onto the tower crane structure through a discharge hopper. A stepper motor drives a lead screw to rotate, thereby moving the discharge hopper and dust concentration sensor horizontally. When the dust concentration sensor detects excessively high powder concentration, the exhaust fan operates to generate suction, and the powder in the spraying chamber enters the air pipe through the discharge hopper, thereby reducing the powder concentration in the spraying chamber. The operation is simple and convenient for changing the powder concentration in the spraying chamber.

[0017] 2. In this utility model, the accumulation chain is used for conveying tower crane structural components on the production line, and the loading station is used to place the structural components to be processed; the shot blasting chamber improves the coating adhesion by shot blasting to remove rust; the pretreatment chamber performs pretreatment such as degreasing; the water blowing chamber removes surface moisture; the moisture drying thoroughly dries the tower crane structural components; the pure water unit provides pure water for pretreatment; the zinc spraying chamber and the powder spraying chamber complete the corresponding coating operations. The process layout of this production line is U-shaped and ring-shaped, which aims to optimize the production process, improve production efficiency and quality, and reduce waste and transportation time.

An output pump 21 is fixedly installed at the center of the bottom end of 15. A material guiding assembly 17 is provided on the output pump 21. The material guiding assembly 17 includes a rigid pipe 1701, a flexible pipe 1702, a discharge hopper 1703, a self-locking motor 1704, two rotating shafts 1705, a flow meter 1706, an air pipe 1707, an exhaust fan 1708, and a valve 1709. The top and bottom ends of the rigid pipe 1701 are fixedly connected to the output pump 21 and the flexible pipe 1702, respectively. The bottom end of the flexible pipe 1702 is fixedly connected to the discharge hopper 1703. A dust concentration sensor 20 is installed inside the powder spraying chamber 9.

[0027] Furthermore, the two rotating shafts 1705 are fixedly connected to the discharge hopper 1703 at opposite ends, and the other end of one of the rotating shafts 1705 is fixedly connected to the self-locking motor 1704. The flow meter 1706 is fixedly installed on the hose 1702, the exhaust fan 1708 is fixedly installed on one side of one of the connecting plates 16, the two ends of the air pipe 1707 are fixedly connected to the exhaust fan 1708 and the rigid pipe 1701 respectively, and the valve 1709 is fixedly installed on the air pipe 1707.

[0028] Furthermore, a moving component 19 is provided on the dust concentration sensor 20. The moving component 19 includes a stepper motor 1901, a lead screw 1902, a slider 1903, a slide bar 1904, and two upright plates 1905. The dust concentration sensor 20 is fixedly installed at the bottom end of the slider 1903. The stepper motor 1901 is fixedly installed at the rear side of the powder spraying chamber 9, and the output shaft end of the stepper motor 1901 is fixedly connected to the lead screw 1902. One end of the lead screw 1902 and the slide bar 1904 both pass through the slider 1903. The lead screw 1902 is movably connected to the accumulation chain 1 through a bearing, and the slide bar 1904 is fixedly connected to the powder spraying chamber 9. The top ends of the two upright plates 1905 are fixedly connected to the slider 1903. One upright plate 1905 is fixedly connected to the self-locking motor 1704, and the other upright plate 1905 is movably connected to another rotating shaft 1705 through a bearing. The front side of the powder spraying chamber 9 is movably connected to the chamber door 18 through a latch.

[0029] The usage method of this embodiment is as follows:

[0030] In operation, the output pump 21 is started, drawing powder from the storage tank 15 and injecting it into the discharge hopper 1703 through the rigid pipe 1701 and the flexible pipe 1702. The discharge hopper 1703 sprays powder onto the tower crane structure. The self-locking motor 1704 is started, driving the two rotating shafts 1705 to rotate, thereby rotating the discharge hopper 1703. The angle of the discharge hopper 1703 can be adjusted as needed. Simultaneously, the flow meter 1706 monitors the powder output. The stepper motor 1901 is started, driving the lead screw 1902 to rotate. Since the lead screw 1902 is threadedly connected to the slider 1903, and the slider 1904 restricts the rotation of the slider 1903, the lead screw 1902 can rotate. The sliding block 1903 moves horizontally, thereby driving the discharge hopper 1703 and the dust concentration sensor 20 to move horizontally, adjusting the position of the discharge hopper 1703. When the dust concentration sensor 20 detects an excessively high powder concentration, the exhaust fan 1708 is activated. The exhaust fan 1708 generates suction, and the powder in the powder spraying chamber 9 enters the air pipe 1707 through the discharge hopper 1703, thereby reducing the powder concentration in the powder spraying chamber 9. It is worth noting that the output end of the exhaust fan 1708 is equipped with a discharge pipe, which can transport excess powder. The operation is simple and convenient for changing the powder concentration in the powder spraying chamber 9. When the valve 1709 is closed, the powder in the rigid pipe 1701 cannot enter the exhaust fan 1708 through the air pipe 1707.

[0031] The accumulation chain 1 is used for conveying tower crane structural components on the production line; the loading station 2 is used to place structural components to be processed; the shot blasting chamber 3 improves coating adhesion by shot blasting to remove rust; the pretreatment chamber 4 performs pretreatment such as degreasing; the water blowing chamber 5 removes surface moisture; the moisture drying chamber 6 thoroughly dries the tower crane structural components; the pure water unit 7 provides pure water for pretreatment; the zinc spraying chamber 8 and the powder spraying chamber 9 complete the corresponding coating operations; the infrared preheating chamber 10 preheats the workpieces for subsequent processes; the curing chamber 11 cures the coating; the strong cooling chamber 12 rapidly cools the workpieces; the central control room 13 achieves fully automated control of the entire line; and the unloading station 14 completes product output. The process layout of this production line is U-shaped and circular, aiming to optimize the production process, improve production efficiency and quality, and reduce waste and transportation time.
