Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a multifunctional safety protection device for lifting chain production equipment. Background Technology

[0002] A lifting chain is a transmission and conveying device composed of a series of chain links. It is mainly used for lifting materials vertically or at an incline. Typically made of high-strength materials such as high-quality alloy steel or stainless steel, it features simple structure, high strength, large load-bearing capacity, good wear resistance, and strong corrosion resistance. In various fields such as industrial production, port logistics, mining, and construction engineering, lifting chains are widely used for loading and unloading goods, lifting materials and equipment, and are indispensable equipment in these fields. At the same time, to ensure the safety of equipment and personnel, lifting chains also have reliable safety performance and can withstand huge loads and impacts. During purchase and use, it is necessary to select the appropriate type, specifications, and material according to specific needs and environmental conditions, and to perform regular maintenance and upkeep to ensure normal operation and extend service life.

[0003] During the chain production process, paint is sprayed onto the surface of the metal chain to improve its rust resistance.

[0004] For example, Chinese Patent No. CN222000483U discloses a metal chain surface spraying device, which includes a chain body and a support fixedly connected to the top outer wall of the base. The support is provided with a guide assembly and an auxiliary drying structure. A support block is fixedly connected to one side of the support near the top, and a spray head is fixedly connected to the bottom surface of the support block. A material box is fixedly connected to the top outer wall of the base, and an infusion pump is fixedly connected to the top outer wall of the material box. The inlet and outlet ports of the infusion pump are respectively connected to the outlet end of the material box and the inlet end of the spray head through conduits. The guide assembly includes two sprockets that are rotatably connected to one side of the support and mesh with the chain body.

[0005] During the automatic traction and displacement of the chain, the aforementioned device, in conjunction with the auxiliary drying structure, achieves the surface drying of the painted chain body, allowing painting and drying to proceed sequentially without the need to manually change the painting position of the chain body, thereby improving the painting efficiency of the chain body.

[0006] However, during the painting process, the aforementioned equipment releases a large number of paint particles into the surrounding environment. These particles not only pollute the air but may also pose a potential threat to the health of nearby personnel, including but not limited to causing respiratory discomfort, allergic reactions, and even more serious consequences with long-term exposure. Therefore, we propose a multi-functional safety protection device to enhance the production chain equipment. Utility Model Content

[0028] Please refer to Figures 1 to 4 As shown, this embodiment provides a multi-functional safety protection device for lifting chain production equipment, including a base 1 and a chain surface painting device 4 for painting the surface of the lifting chain. The chain surface painting device 4 in this embodiment adopts a metal chain surface painting device disclosed in the patent with announcement number CN222000483U. Its specific structure and working principle are existing technologies and will not be described here.

[0029] The chain surface painting device 4 is fixedly installed on the base 1. The protective shell 2 is fixedly installed on the base 1. The chain surface painting device 4 is located inside the protective shell 2. A door panel 3 is hinged to one side of the protective shell 2. A feed port 201 is opened on one side of the protective shell 2.

[0030] The protective shell 2 is equipped with a filtration mechanism, which includes a filter box 10 and a negative pressure fan 12. The filter box 10 is fixedly installed on one side of the protective shell 2, and the negative pressure fan 12 is fixedly installed at the bottom of the filter box 10. The filter element 11 is installed inside the filter box 10. The air inlet of the negative pressure fan 12 is connected to the lower end of the filter box 10. A first air collection hood 13 is provided at the upper end of the interior of the protective shell 2. A second connecting pipe 8 is connected to the top of the first air collection hood 13. A first connecting pipe 9 is connected to the upper end of the filter box 10. The first connecting pipe 9 is connected to the second connecting pipe 8. In this embodiment, a valve 801 is installed on the second connecting pipe 8.

[0031] A second gas collection hood 6 is installed at the feed inlet 201. The second gas collection hood 6 is connected to the first connecting pipe 9 through a third connecting pipe 7.

[0032] By adopting the above technical solution, during use, the chain passes through the feed inlet 201 into the protective shell 2, then the door panel 3 is opened, and the worker installs the chain on the chain surface painting device 4, turns on the chain surface painting device 4, and then closes the door panel 3 to perform the painting operation on the chain. At the same time, the negative pressure fan 12 is turned on, and the valve 801 is in the closed state. The paint particles overflowing from the feed inlet 201 are collected by the second gas collection hood 6 and enter the filter box 10 through the third connecting pipe 7 and the first connecting pipe 9 for filtration. When all the material bars are painted, the valve 801 is opened, and the paint particles floating in the protective shell 2 are collected by the first gas collection hood 13 and enter the filter box 10 through the second connecting pipe 8 and the first connecting pipe 9 for filtration. After the suction is completed, the door panel 3 can be opened to replace the next chain.

[0033] In this embodiment, a horizontal roller 2011 is rotatably installed inside the feed inlet 201, and a vertical roller 2012 is rotatably installed on the side of the protective shell 2 near the feed inlet 201. There are two vertical rollers 2012, which are respectively arranged on both sides of the feed inlet 201. By using the horizontal roller 2011 and the vertical roller 2012, the chain can be effectively prevented from directly contacting the feed inlet 201, thereby preventing the feed inlet 201 from being worn.

[0035] The PM2.5 sensor 14 can monitor the PM2.5 content inside the protective shell 2 in real time, thereby determining whether the paint particles inside the protective shell 2 have been cleaned. When the PM2.5 content inside the protective shell 2 exceeds the set threshold, the controller controls the alarm light 15 to emit an alarm light. When the PM2.5 content in the protective shell 2 is lower than the set threshold, the controller controls the alarm light 15 to emit a normal indicator light.

[0036] In this embodiment, the PM2.5 sensor 14 is a PM2.5 sensor with model number GP2Y1051AU0F. The controller is a DSP controller.

[0037] In this embodiment, the surface of the control box 16 is equipped with a first button group for controlling the switch of valve 801, a second button group for controlling the switch of negative pressure fan 12, and a third button group for controlling the start and stop of chain surface painting device 4.
