Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of explosion-proof workstation boxes, and in particular relates to an explosion-proof workstation box used in an explosion-proof painting area. Background Technology
[0002] Coating is an important part of modern product manufacturing processes. The quality of rust-proof and corrosion-proof coatings is one of the important aspects of overall product quality. The appearance quality of a product not only reflects its protective and decorative performance, but is also an important factor in its value.
[0003] In existing automotive painting production line control systems, some explosion-proof chambers require manual operation, such as the wax injection chamber in the painting workshop. After the robot automatically injects wax, some cavities are formed. These cavities can lead to electrochemical corrosion, reducing the vehicle's corrosion resistance. Therefore, manual wax injection is necessary to fill these cavities. Because wax injection chambers are prone to explosion, ordinary workstation boxes can only be installed outside the chamber. Workers need to move in and out of the chamber, or multiple people need to work together, wasting a lot of time and posing safety hazards. Furthermore, when common workstation boxes are damaged, they need to be disassembled and repaired by personnel, which requires the use of different tools, making the process cumbersome. Therefore, we propose an explosion-proof workstation box for use in explosion-proof painting areas. Utility Model Content
[0004] The purpose of this invention is to provide an explosion-proof workstation box for use in explosion-proof painting areas, so as to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides an explosion-proof workstation box for use in an explosion-proof painting area, comprising:
[0006] A fixed frame is provided with an explosion-proof enclosure on one side. An explosion-proof indicator light 1, an explosion-proof indicator light 2, an explosion-proof button 1, an explosion-proof button 2, and an explosion-proof button 3 are fixedly installed on one side of the explosion-proof enclosure. A connector is fixedly installed at the bottom of the explosion-proof enclosure. An arc-shaped plate 1 is provided around the periphery of the connector. An arc-shaped plate 2 is rotatably installed on one side of the arc-shaped plate 1. A screw is threaded on the arc-shaped plate 2, and one end of the screw passes through the arc-shaped plate 1.
[0007] A fixing groove is provided on one side of the fixing frame. A fixing block is fixedly installed on the other side of the explosion-proof box and inside the fixing groove. A sliding groove is provided on the other side of the explosion-proof box and above the fixing block. A limit block is slidably installed in the sliding groove, and the top of the limit block extends into the fixing groove.
[0008] A drive assembly, located inside an explosion-proof enclosure, is used to drive the limit block to move.
[0009] In this technical solution, the explosion-proof enclosure is installed inside the wax injection chamber, ensuring that personnel do not need to enter and exit the wax injection chamber during use, which is more convenient, reduces on-site operation time, and improves work efficiency.
[0010] The explosion-proof enclosure is an increased safety type shell made of cast aluminum alloy with high internal density and strong impact resistance. The explosion-proof indicator light 1, explosion-proof indicator light 2, explosion-proof button 1, and explosion-proof button 2 are electrical components that have passed the EX explosion-proof certification. The wiring inside the explosion-proof enclosure is completed at the factory. When wiring on site, only a single-ended M25 pre-cast cable is needed to connect the explosion-proof workstation box to the I / O module, which ensures increased operational safety in the explosion-proof area and is simple and convenient to use.
[0011] The drive component moves the limit block downwards until its top end moves out of the groove in the fixing slot. At this point, the limit block releases the explosion-proof enclosure. Then, the personnel rotate the explosion-proof enclosure to move the limit block out of the fixing slot. The explosion-proof enclosure can then be moved upwards, which will move the fixing block upwards until it moves out of the fixing slot. The explosion-proof enclosure can then be removed, ensuring that it can be easily removed and repaired without the need for additional tools.
[0012] In the above technical solution, the driving component further includes:
[0013] A spring is fixedly installed in the sliding groove and located below the limiting block. A sliding rod is fixedly installed on the top of the limiting block, and the top end of the sliding rod passes through the top of the sliding groove and extends to the outside.
[0014] In this technical solution, when the explosion-proof enclosure is damaged, personnel can press down on the sliding rod. The downward movement of the sliding rod will cause the limiting block to move downward. The downward movement of the limiting block will compress the spring and retract it until the top of the limiting block moves out of the groove in the fixing slot. At this point, the limiting block can release the explosion-proof enclosure. Then, personnel can rotate the explosion-proof enclosure to move the limiting block out of the fixing slot. At this point, the explosion-proof enclosure can be moved upward. The upward movement of the explosion-proof enclosure will cause the fixing block to move upward until it moves out of the fixing slot. At this point, the explosion-proof enclosure can be removed, ensuring that personnel can easily remove the explosion-proof enclosure for repair. Moreover, no other disassembly tools are needed during the disassembly process, which is quite convenient.
[0015] In the above technical solution, the two ends of the spring are respectively welded tightly to the bottom of the limiting block and the sliding groove, and the sliding rod is slidably connected to the sliding groove and the explosion-proof box.
[0016] In this technical solution, the structure of the spring is ensured to be stable, guaranteeing that the sliding rod can slide normally within the sliding groove and the explosion-proof enclosure.
[0017] In the above technical solution, the bottom end of the fixing block is engaged with the fixing groove, and the top end of the limiting block is inserted into the fixing groove.
[0018] In this technical solution, it is ensured that the bottom end of the fixing block can be engaged in the fixing groove, and that the top end of the limiting block can be inserted into the fixing groove.
[0019] In the above technical solution, the cross-sections of both the fixing block and the limiting block are L-shaped.
[0020] In this technical solution, the fixing block and the limiting block are ensured to fix the explosion-proof box onto the fixing frame.
[0021] In the above technical solution, one end of the screw is further connected to the arc-shaped plate by a thread.
[0022] In this technical solution, it is ensured that the rotation of the screw can secure the first and second arc-shaped plates.
[0023] The beneficial effects of this utility model are:
[0024] 1. The explosion-proof workstation box used in the explosion-proof painting area has an explosion-proof enclosure installed inside the wax injection chamber. This ensures that personnel do not need to enter and exit the wax injection chamber during use, which is more convenient, reduces on-site operation time, and improves work efficiency.
[0025] 2. The explosion-proof workstation box used in the explosion-proof painting area features an increased safety enclosure made of cast aluminum alloy with high internal density and strong impact resistance. The explosion-proof indicator lights 1, 2, 1, and 2 are all EX-certified electrical components. The wiring inside the enclosure is pre-installed at the factory; on-site wiring only requires a single-ended M25 pre-cast cable to connect the workstation box to the I / O module, ensuring increased operational safety in the explosion-proof area and providing simple and convenient operation.
[0026] 3. The explosion-proof workstation box used in the explosion-proof painting area has a drive component that moves a limit block downwards until the top of the limit block moves out of the groove in the fixing slot. At this point, the limit block can release the explosion-proof box. Then, the personnel can rotate the explosion-proof box to move the limit block out of the fixing slot. The explosion-proof box can then be moved upwards, which will move the fixing block upwards until it moves out of the fixing slot. At this point, the explosion-proof box can be removed, ensuring that the personnel can easily remove the explosion-proof box for maintenance. Moreover, no other disassembly tools are needed during the disassembly process, which is quite convenient. Attached Figure Description

[0040] Example 1:
[0041] Please see Figure 1 - Figure 6 As shown, this embodiment provides an explosion-proof workstation box for use in an explosion-proof painting area, comprising:
[0042] A fixed frame 1 is provided on one side of the fixed frame 1. An explosion-proof box 2 is provided on one side of the explosion-proof box 2. An explosion-proof indicator light 1 3, an explosion-proof indicator light 2 4, an explosion-proof button 1 5, an explosion-proof button 2 6 and an explosion-proof button 3 7 are fixedly installed on one side of the explosion-proof box 2.

One end of the screw 11 passes through the arc-shaped plate 1 9.
[0043] A fixing groove 12 is provided on one side of the fixing frame 1. A fixing block 13 is fixedly installed on the other side of the explosion-proof box 2 and inside the fixing groove 12. A sliding groove 14 is provided on the other side of the explosion-proof box 2 and above the fixing block 13. A limiting block 15 is slidably installed in the sliding groove 14, and the top of the limiting block 15 extends into the fixing groove 12.
[0044] The drive assembly is located inside the explosion-proof enclosure 2 and is used to drive the limit block 15 to move.
[0045] Among them, the explosion-proof enclosure 2 is installed inside the wax injection chamber, which ensures that personnel do not need to enter and exit the wax injection chamber when using it, which is more convenient, reduces on-site operation time, and improves work efficiency.
[0046] The explosion-proof enclosure 2 is an increased safety type shell made of cast aluminum alloy with high internal density and strong impact resistance. Explosion-proof indicator lights 1-3, 2-4, 1-5, and 2-6 are electrical components that have passed explosion-proof certification EX. The wiring inside the explosion-proof enclosure 2 is completed at the factory. When wiring on site, only a single-ended M25 pre-cast cable is needed to connect the explosion-proof workstation box to the I / O module, ensuring increased operational safety in the explosion-proof area and making it simple and convenient to use.
[0047] The drive component moves the limit block 15 downwards until its top end moves out of the groove in the fixing slot 12. At this point, the limit block 15 releases the explosion-proof enclosure 2. Then, the personnel rotate the explosion-proof enclosure 2 to move the limit block 15 out of the fixing slot 12. The explosion-proof enclosure 2 can then be moved upwards. The upward movement of the explosion-proof enclosure 2 will move the fixing block 13 upwards until the fixing block 13 is moved out of the fixing slot 12. At this point, the explosion-proof enclosure 2 can be removed, ensuring that it is easy for personnel to remove and repair the explosion-proof enclosure 2. Furthermore, no other disassembly tools are needed during the disassembly process, which is quite convenient.
[0048] Example 2:
[0049] This embodiment provides an explosion-proof workstation box for use in an explosion-proof coating area. In addition to the technical solutions described in the above embodiments, it also has the following technical features, including a drive component comprising:
[0050] Spring 16 is fixedly installed in the sliding groove 14 and located below the limiting block 15. A sliding rod 17 is fixedly installed on the top of the limiting block 15. The top end of the sliding rod 17 passes through the top of the sliding groove 14 and extends to the outside.
[0051] When the explosion-proof enclosure 2 is damaged, personnel can press down on the sliding rod 17. The downward movement of the sliding rod 17 will cause the limiting block 15 to move downward. The downward movement of the limiting block 15 will compress the spring 16 and cause it to contract until the top of the limiting block 15 moves out of the groove in the fixing slot 12. At this time, the limiting block 15 can release the limiting of the explosion-proof enclosure 2. Then, personnel can rotate the explosion-proof enclosure 2 so that the limiting block 15 moves out of the fixing slot 12. At this time, the explosion-proof enclosure 2 can be moved upward. The upward movement of the explosion-proof enclosure 2 will cause the fixing block 13 to move upward until the fixing block 13 moves out of the fixing slot 12. At this time, the explosion-proof enclosure 2 can be removed. This ensures that personnel can easily remove the explosion-proof enclosure 2 for repair, and no other disassembly tools are needed during the disassembly process, which is quite convenient.
[0052] Example 3:
[0053] This embodiment provides an explosion-proof workstation box for use in an explosion-proof coating area. In addition to the technical solutions of the above embodiments, it also has the following technical features: the two ends of the spring 16 are respectively located at the bottom of the limiting block 15 and the sliding groove 14 and are tightly welded; the sliding rod 17 is slidably connected to the sliding groove 14 and the explosion-proof box 2.
[0054] This ensures the structural stability of the spring 16 and guarantees that the sliding rod 17 can slide normally within the sliding groove 14 and the explosion-proof enclosure 2.
[0055] Example 4:
[0056] This embodiment provides an explosion-proof workstation box for use in an explosion-proof coating area. In addition to the technical solutions of the above embodiments, it also has the following technical features: the bottom end of the fixing block 13 is engaged with the fixing groove 12, and the top end of the limiting block 15 is inserted into the fixing groove 12.
[0057] Specifically, it is ensured that the bottom end of the fixing block 13 can be inserted into the fixing groove 12, and that the top end of the limiting block 15 can be inserted into the fixing groove 12.
[0058] Example 5:
[0059] This embodiment provides an explosion-proof workstation box for use in an explosion-proof coating area. In addition to the technical solutions of the above embodiments, it also has the following technical features: the cross-sections of the fixing block 13 and the limiting block 15 are both L-shaped.
[0060] Among them, the fixing block 13 and the limiting block 15 can fix the explosion-proof box 2 on the fixing frame 1.
[0061] Example 6:
[0062] This embodiment provides an explosion-proof workstation box for use in an explosion-proof coating area. In addition to the technical solution of the above embodiment, it also has the following technical features: one end of the screw 11 is threadedly connected to the arc plate 9.
[0063] This ensures that the rotation of screw 11 can secure the arc-shaped plate 9 and the arc-shaped plate 10.
[0064] It is worth noting that the explosion-proof enclosure 2 is installed inside the painting chamber. The incoming cable passes through the chamber via an explosion-proof flexible conduit. The conduit has connectors 8 at both ends. One end is connected to the bottom of the explosion-proof enclosure 2 and secured by arc-shaped plates 9 and 10, as well as screws 11. Personnel can rotate screws 11, which, under the action of the threads, tightens arc-shaped plates 9 and 10, thus securing one end of the explosion-proof flexible conduit. The other end is connected to an opening in the painting chamber. The area around the opening in the painting chamber needs to be treated with explosion-proof putty. The incoming cable enters the cable tray through the explosion-proof flexible conduit and connects to the I / O module. The explosion-proof enclosure 2 can then communicate with the PLC to control the process equipment and conveying equipment in the painting production workshop. The connectors 8 are M25 connectors to ensure easy connection by personnel.
[0065] Working principle: During use, explosion-proof indicator light 1 (3) is the pause indicator, explosion-proof indicator light 2 (4) is the position stop indicator, and explosion-proof button 1 (5) is the pause button. When personnel press explosion-proof button 1 (5), explosion-proof indicator light 1 (3) will light up. Explosion-proof button 2 (6) is the position stop button. When personnel press explosion-proof button 2 (6), explosion-proof indicator light 2 (4) will light up. Explosion-proof button 3 (7) is the restart button. When personnel press explosion-proof button 3 (7), explosion-proof indicator lights 1 (3) and 2 (4) will turn off, ensuring ease of use for personnel. At the same time, the entire device is installed inside the wax injection chamber, ensuring that personnel do not need to enter and exit the wax injection chamber during use, which is more convenient, reduces on-site operation time, and improves work efficiency.
[0066] Among them, the explosion-proof enclosure 2 is an increased safety type shell made of cast aluminum alloy with high internal density and strong impact resistance. The explosion-proof indicator light 1 3, explosion-proof indicator light 2 4, explosion-proof button 1 5 and explosion-proof button 2 6 are electrical components that have passed the explosion-proof certification EX. The wiring inside the explosion-proof enclosure 2 has been completed at the factory. When wiring on site, only a single-ended M25 pre-cast cable is needed to connect the explosion-proof workstation box to the I / O module, which ensures increased operational safety in the explosion-proof area and is simple and convenient to use.
[0067] When the explosion-proof enclosure 2 is damaged, personnel can press down on the sliding rod 17. The sliding rod 17 moves downward, which will cause the limiting block 15 to move downward. The limiting block 15 moves downward, which will compress the spring 16 and retract it until the top of the limiting block 15 moves out of the groove in the fixing slot 12. At this time, the limiting block 15 can release the limiting of the explosion-proof enclosure 2. Then, personnel can rotate the explosion-proof enclosure 2 so that the limiting block 15 moves out of the fixing slot 12. At this time, the explosion-proof enclosure 2 can be moved upward. The upward movement of the explosion-proof enclosure 2 will cause the fixing block 13 to move upward until the fixing block 13 moves out of the fixing slot 12. At this time, the explosion-proof enclosure 2 can be removed, ensuring that personnel can easily remove the explosion-proof enclosure 2 for repair. Moreover, no other disassembly tools are needed during the disassembly process, which is quite convenient.
[0068] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
