Description

Technical Field

[0001] This utility model belongs to the field of protective frame technology, specifically a sheet metal composite protective frame. Background Technology

[0002] In modern industrial production systems, equipment protective frames are key components that ensure production safety and maintain stable equipment operation. Their performance directly affects production efficiency and personnel safety. With the rapid development of fields such as machining and automated manufacturing, higher requirements are placed on the flexibility, protective performance, and ease of cleaning and maintenance of protective frames.

[0003] Traditional protective frames mostly adopt an integral structural design. Although such frames have a certain protective capability, they have revealed many limitations in practical applications. First, integral frames are difficult to adapt to the protection needs of equipment of different sizes and shapes. The installation and disassembly process is complicated, and they occupy a lot of space during transportation, resulting in increased usage costs. Second, in production scenarios such as metal cutting, casting, and welding, flying metal shavings, oil stains, coolant and other contaminants are very easy to adhere to the inner wall of the protective frame. This not only affects the aesthetics and cleanliness of the frame, but the residual debris may also bounce back, causing accidental injury to operators or entering the equipment and interfering with its normal operation.

[0004] Therefore, a sheet metal composite protective frame is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a sheet metal modular protective frame, which has the advantages of flexible assembly to adapt to different equipment needs through splicing of unit panels, and the use of air curtains to effectively prevent pollutant adhesion and block debris rebound.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sheet metal composite protective frame, comprising a composite frame body, wherein an airflow blocking protective component is installed on the composite frame body;

[0007] The main body of the combined frame includes unit plates. The edge of the unit plate is fixedly connected to a fixing lug near the corner. The fixing lugs of adjacent unit plates on the same plane are connected by a first bolt. An L-shaped connector is provided between two vertically arranged unit plates on different planes. The L-shaped connector is connected to the corresponding fixing lug by a second bolt.

[0008] The airflow blocking and protection component includes an exhaust pipe located on the inner wall of the side of the main body of the combined frame near the top. The bottom of the exhaust pipe is equipped with equidistant exhaust ports. The exhaust pipe is connected to a guide pipe, and the end of the guide pipe is connected to a fan. The fan is located on the main body of the combined frame.

[0009] Preferably, a sealing strip is provided between adjacent unit plates, and both the fixing ear and the L-shaped connector are provided with through holes for the first bolt and the second bolt to pass through.

[0010] Preferably, a support frame is connected to the top of the main body of the combined frame, and the fan is mounted on the support frame.

[0011] Preferably, the support frame includes a horizontal plate disposed on the top of the main body of the combined frame, the horizontal plate being connected to the main body of the combined frame by a third bolt, and a mounting plate being fixedly connected to the top of the horizontal plate by a vertical rod, and the fan being mounted on the mounting plate.

[0012] Preferably, an airflow guiding component is provided on the inner wall of the combined frame body at a position corresponding to the exhaust port. The airflow guiding component includes an air collecting groove that is close to the inner wall of the combined frame body, and an exhaust port is provided on the combined frame body at a position corresponding to the air collecting groove.

[0013] Preferably, a connecting plate is fixedly connected to the bottom of the air collection trough, and the connecting plate is connected to the main body of the combined frame by a fourth bolt.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The main body of this utility model's combined frame adopts a unit panel splicing structure. The edge fixing ears, together with the first bolt, L-shaped connector and the second bolt, can achieve free assembly in multiple dimensions and specifications. It can quickly adapt to the shape and installation requirements of different equipment. The number of unit panels and splicing method can be flexibly increased or decreased according to the size of the new equipment, which can greatly shorten the installation and debugging cycle and reduce the modification cost. It can also be disassembled into small unit panels during transportation, which can effectively save space and improve logistics efficiency.

[0016] 2. This utility model's airflow barrier protection component, through the coordinated design of the fan, air duct, and exhaust pipe, forms a stable air curtain on the top of the inner wall of the main side of the combined frame. The air curtain can generate directional airflow, effectively blocking splashing debris, oil, and other pollutants, preventing them from adhering to the inner wall of the frame. The air curtain can change the trajectory of high-speed splashing metal debris in advance, preventing debris from impacting and rebounding and injuring operators. In chemical production environments, the air curtain can also help block corrosive gases, reduce the risk of corrosion of the frame material, and extend its service life. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 5 As shown, this utility model provides a sheet metal composite protective frame, including a composite frame body 1, on which an airflow blocking protective component 2 is installed.

[0028] The main body 1 of the combined frame includes a unit plate 101. A fixing lug 102 is fixedly connected to the edge of the unit plate 101 near the corner. The fixing lugs 102 of adjacent unit plates 101 on the same plane are connected by a first bolt 103. An L-shaped connector 104 is provided between two vertically arranged unit plates 101 on different planes. The L-shaped connector 104 is connected to the corresponding fixing lug 102 by a second bolt 105.

[0029] The main body 1 of the combined frame adopts a unit panel 101 splicing structure. The edge fixing lugs 102, together with the first bolt 103, L-shaped connector 104 and second bolt 105, can achieve multi-dimensional and multi-specification free assembly, which can quickly adapt to the shape and installation requirements of different equipment. The number of unit panels 101 and the splicing method can be flexibly increased or decreased according to the size of the new equipment, which can significantly shorten the installation and commissioning cycle and reduce the modification cost. During transportation, it can also be disassembled into small unit panels 101, which can effectively save space and improve logistics efficiency.

[0030] The airflow blocking and protection component 2 includes an exhaust pipe 201 located on the inner side wall of the main body 1 near the top. The bottom of the exhaust pipe 201 is equipped with equidistant exhaust ports 202. The exhaust pipe 201 is connected to a guide pipe 203. The end of the guide pipe 203 is connected to a fan 204. The fan 204 is located on the main body 1 of the combined frame.

[0031] The airflow barrier protection component 2, through the linkage design of the fan 204, the air duct 203 and the exhaust duct 201, forms a stable air curtain on the top of the inner wall of the side of the main body of the combined frame 1. The air curtain can generate directional airflow, effectively blocking splashed debris, oil and other pollutants, preventing them from adhering to the inner wall of the frame. The air curtain can change the trajectory of high-speed splashed metal debris in advance, preventing debris from impacting and rebounding and injuring operators. In chemical production environments, the air curtain can also help block corrosive gases, reduce the risk of corrosion of the frame material and extend its service life.

[0032] Specifically, a sealing strip is provided between adjacent unit plates 101, and through holes are provided on the fixing ear 102 and the L-shaped connector 104 for the first bolt 103 and the second bolt 105 to pass through.

[0033] Furthermore, a support frame 3 is connected to the top of the main body 1 of the combined frame, and the fan 204 is mounted on the support frame 3.

[0034] Furthermore, the support frame 3 includes a horizontal plate 301 located on the top of the main body 1 of the combined frame. The horizontal plate 301 is connected to the main body 1 of the combined frame by a third bolt 302. The top of the horizontal plate 301 is fixedly connected to an mounting plate 304 by a vertical rod 303. The fan 204 is mounted on the mounting plate 304.

[0035] It is worth noting that an airflow guiding component 4 is provided on the inner wall of the main body 1 of the combined frame, corresponding to the position of the exhaust port 202. The airflow guiding component 4 includes an air collecting groove 401 that is close to the inner wall of the main body 1 of the combined frame, and an exhaust port 402 is provided on the main body 1 of the combined frame at the position corresponding to the air collecting groove 401. The design of the air collecting groove 401 and the exhaust port 402 in the airflow guiding component 4 forms a scientific guiding system with the airflow of the air curtain. The air curtain carries pollutants such as debris and dust to the air collecting groove 401 and quickly discharges them outside the frame through the exhaust port 402.

[0036] It is worth noting that a connecting plate 403 is fixedly connected to the bottom of the air collection duct 401, and the connecting plate 403 is connected to the main body of the combined frame 1 by the fourth bolt 404.

[0037] Among them, the fan 204 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, a controller and a switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0038] Working principle and process: During installation, adjacent unit plates 101 on the same plane are connected by passing the first bolt 103 through the through hole of the fixing lug 102. The L-shaped connector 104 and the second bolt 105 are used to splice vertical unit plates 101 on different planes to form the main body of the combined frame 1. Simultaneously, sealing strips are embedded between adjacent unit plates 101 to enhance sealing. The horizontal plate 301 is fixed to the top of the main body of the combined frame 1 by the third bolt 302. The vertical rod 303 connects the horizontal plate 301 and the mounting plate 304 to form a support frame 3. 4. A fixed fan 204 is installed on the upper part; the fan 204 is connected to the exhaust pipe 201 through the air guide pipe 203, so that the airflow generated by the fan 204 enters the exhaust pipe 201 through the air guide pipe 203 and is discharged from the exhaust port 202 to form an air curtain on the inner wall of the side of the frame, blocking the adhering of pollutants; when the airflow carries debris and other pollutants and falls down, the air collection trough 401 collects the airflow and pollutants and discharges them through the exhaust port 402, thereby achieving the protection and internal cleaning of the equipment. The air collection trough 401 is fixed to the inner wall of the frame body 1 through the connecting plate 403 and the fourth bolt 404.
