Description

Technical Field

[0001] The present application relates to the technical field of PLC control cabinets, and in particular to an intelligent PLC control cabinet. Background Art

[0002] PLC control cabinet is a device used to control and monitor industrial automation systems. PLC (Programmable Logic Controller) is a digital computer that can receive input signals, perform logical operations and generate output signals to control mechanical equipment and technological processes.

[0003] In the prior art, the installation of a PLC control cabinet usually involves transporting the cabinet to the installation location, welding a mounting bracket inside the cabinet, mounting electrical components on the mounting bracket, mounting the control device on the outside of the cabinet door, and connecting electrical wires to the electrical components. This completes the installation of the PLC control cabinet.

[0004] However, in order to reserve a certain amount of installation space for the control equipment, the installation bracket inside the cabinet is usually located deeper in the cabinet, and the front of the installation bracket is the reserved installation space, so that when the cabinet door is closed, the control equipment will not hinder the closing of the cabinet door. However, this also leads to that when the staff repair the electrical components inside the cabinet, the maintenance space of the staff will be limited due to the obstruction of the inner wall of the cabinet, which makes it very inconvenient for the staff to repair the electrical components inside the cabinet. Some technicians have proposed to open up both sides of the cabinet and install removable baffles to facilitate the staff to repair the electrical components inside the cabinet. However, if the staff needs to repair the electrical components on both sides of the installation bracket, the staff needs to remove the baffles on both sides of the cabinet and go around the cabinet, which is very inconvenient. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of this application is to provide an intelligent PLC control cabinet to solve the technical problem in the prior art of inconvenient maintenance of electrical components inside the cabinet.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: an intelligent PLC control cabinet, comprising a cabinet body, a cabinet door hingedly connected to one side of the cabinet body, and a mounting bracket installed inside the cabinet body, a slide rail fixedly provided on the bottom surface of the cabinet body, the slide rail being arranged along the width direction of the cabinet body, a movable wheel being rotatably provided on the bottom surface of the mounting bracket, the movable wheel being located in the slide rail, a limiting structure being provided on the top surface of the cabinet body and the top surface of the mounting bracket to prevent the mounting bracket from tipping over, and a plurality of movable wheels being provided and respectively located at the front and rear ends of the mounting bracket.

[0007] Furthermore, the limiting structure includes a limiting rod fixedly arranged on the top surface of the mounting bracket and a limiting slide groove opened on the top surface inside the cabinet. The limiting slide groove is arranged along the width direction of the cabinet and its length is less than the width of the cabinet. The limiting rod is arranged on a surface of the mounting bracket close to the back of the cabinet, and the limiting rod extends into the limiting slide groove.

[0008] By adopting the above technical solution, when the staff needs to repair the electrical components inside the cabinet, they can pull the mounting bracket to make the mounting bracket slide out of the cabinet along the slide rail, so that the staff can easily repair the electrical components on the mounting bracket, and the setting of the slide rail makes it more convenient for the staff to install the mounting bracket inside the cabinet. The staff can first install the electrical components on the mounting bracket outside the cabinet, and then install the mounting bracket inside the cabinet through the slide rail, which makes it more convenient for the staff to install the mounting bracket. Although the setting of the slide rail and the moving wheels makes it more convenient for the staff to repair the electrical components on the mounting bracket, it also causes the moving wheels at the front end to be moved when the staff pulls the mounting bracket to slide out of the cabinet. After being detached from the track, the moving wheel at the rear end is still stuck in the track, which makes the installation bracket as a whole have a tendency to tip over outside the cabinet. If the staff does not pay attention to holding the installation bracket, they may be hit by the installation bracket, which is very dangerous. The setting of the limit structure solves this technical problem. Through the setting of the limit structure, when the installation bracket tips over outside the cabinet, the limit rod will abut against the inner wall of the limit slide groove, thereby providing support for the upper end of the installation bracket to prevent the installation bracket from tipping over, making it safer and more convenient for the staff to pull the installation bracket. The setting of the limit rod also prevents the installation bracket from completely detaching from the cabinet due to excessive force of the staff, which can prevent the situation where the installation bracket is completely detached from the cabinet due to excessive force of the staff and needs to be reinstalled.

[0009] Furthermore, the slide rail is provided with a fixed plug strip, and the fixed plug strip is used to block the slide rail to prevent the mounting bracket from sliding along the slide rail.

[0010] By adopting the above technical solution, although the setting of the limiting structure makes it safer and more convenient for the staff to pull the installation bracket, after the staff pushes the installation bracket to the deepest part of the cabinet and closes the cabinet door, the installation bracket still has a certain sliding space. This results in that if the cabinet is subjected to vibration, the installation bracket will slide inside the cabinet and hit the cabinet door or the deepest surface of the cabinet, causing damage to the electrical components or the control devices on the cabinet door. The setting of the fixed plug strip solves this technical problem. After the inspection is completed and the staff pushes the installation bracket to the deepest part of the cabinet, the fixed plug strip is inserted into the slide rail to abut the moving wheel. This can prevent the installation bracket from moving along the slide rail due to vibration.

[0011] Furthermore, an insertion port is provided at one end of the slide rail away from the deepest part of the cabinet, and the insertion port is located on both sides of the interior of the slide rail. A fixing structure for fixing the fixed plug strip through the insertion port is provided at one end of the fixed plug strip away from the deepest part of the cabinet.

[0012] Furthermore, the fixing structure includes unconnected storage openings on both sides of the fixing plug strip, a plug strip inserted in the storage opening, and a clamping spring located between the inner wall of the storage opening and the end face of the plug strip, one end of the clamping spring is fixedly connected to the end face of one end of the plug strip inserted into the storage opening, and the other end is fixedly connected to a face of the storage opening opposite to the end face of the plug strip.

[0013] By adopting the above technical solution, although the setting of the fixed plug strip can prevent the installation bracket from moving along the slide rail due to vibration, the moving wheel will continue to hit the fixed plug strip during the vibration process. This impact may cause the position of the fixed plug strip to move, causing the installation bracket to move and hit again. The setting of the fixed structure solves this technical problem. After the inspection is completed, the staff pushes the installation bracket to the deepest part of the cabinet, and then presses the plug-in strip to make the plug-in strip press the snap spring to retract into the storage port, and then plugs the fixed plug strip into the slide rail to abut the moving wheel. At this time, the plug-in strip is no longer pressed, so that the snap spring pushes the plug-in strip into the plug port, thereby fixing the fixed plug strip, so that the fixed plug strip will not be displaced due to the impact of the moving wheel, thereby improving the protective effect of the fixed plug strip.

[0014] Furthermore, the receiving opening opens up the end surface of the fixed plug strip away from the back of the cabinet, and an auxiliary handle extends from one end of the plug strip close to the clamping spring toward the direction of the fixed plug strip away from the back of the cabinet.

[0015] By adopting the above technical solution, although the setting of the fixed structure improves the protective effect of the fixed plug strip, when the staff needs to slide the installation bracket out of the cabinet, they need to pull the plug strip into the storage port first before pulling out the fixed plug strip, but the plug strip extended into the plug port is difficult to pull, which makes it more troublesome for the staff to pull out the fixed plug strip. The setting of the auxiliary handle solves this technical problem. When the staff needs to pull out the fixed plug strip and the installation bracket can slide, they pinch the auxiliary handles on the two plug strips close to each other, so that the plug strip compresses the clamping spring and retracts it into the storage port. In this way, the fixed plug strip can be pulled out, making it more convenient for the staff to slide the installation bracket.

[0016] Furthermore, the cabinet door is provided with a protective structure for reducing wire loss of the control device.

[0017] Furthermore, the protective structure includes a connection port opened on the cabinet door and passing through the cabinet door, a rotating shaft passing through the cabinet door through the connection port, and a mounting plate fixedly connected to the rotating shaft. The rotating shaft is rotatably connected to the cabinet body, and the mounting plate is fixedly connected to one end of the rotating shaft close to the mounting bracket.

[0018] By adopting the above technical solution, although the setting of the slide rail and the moving wheel enables the staff to repair the electrical components on the mounting bracket more conveniently, every time the staff pulls the mounting bracket to slide out of the cabinet, the wires connected to the control device will swing with the control device as the base point. This swing will cause creases to appear at the position where the wires are connected to the control device, causing wear of the wires. The setting of the protective structure solves this technical problem. The staff installs the control device on the mounting plate. If the staff pulls the mounting bracket to slide out of the cabinet, the wires will push the mounting plate to rotate, thereby preventing the wires from bending and increasing the service life of the wires.

[0019] Furthermore, the interior of the rotating shaft is hollow and has through openings at both ends, and the through openings penetrate the rotating shaft and the mounting plate.

[0020] By adopting the above technical solution, the control device is installed on the mounting plate, and the connecting wires of the components of the control device installed outside the cabinet door can pass through the cabinet door through the opening, making it more convenient for the staff to install the control device.

[0021] Furthermore, one end of the rotating shaft away from the mounting plate extends out of the cabinet door and is provided with an external thread, and one end of the rotating shaft provided with the external thread is threadedly connected to the auxiliary plate.

[0022] By adopting the above technical solution, although the setting of the through hole makes it more convenient for the staff to install the control device, when the mounting plate rotates, the connecting wires of the components located outside the cabinet door of the control device will be subjected to torque force, resulting in loss of the connecting wires. The setting of the external thread and the auxiliary plate solves this technical problem. The staff installs the main component of the control device in front of the mounting plate, passes the connecting wires through the cabinet door through the through hole, and then installs the main component of the control device on the mounting plate, and then screws the auxiliary plate on the outside of the cabinet door to install the components of the control device on the auxiliary plate. In this way, when the main component of the control device rotates, the components of the control device will also rotate, thereby preventing loss of the connecting wires, and the cabinet door can be clamped by the cooperation of the auxiliary plate and the mounting plate to prevent the entire protective component from falling.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: Through the setting of the slide rail and the moving wheel, when the staff needs to repair the electrical components inside the cabinet, they can pull the mounting bracket to make the mounting bracket slide out of the cabinet along the slide rail, so that the staff can repair the electrical components on the mounting bracket very conveniently. The setting of the slide rail makes it more convenient for the staff to install the mounting bracket inside the cabinet. The staff can first install the electrical components on the mounting bracket outside the cabinet, and then install the mounting bracket inside the cabinet through the slide rail, making it more convenient for the staff to install the mounting bracket.

[0024] By setting the limiting structure, it is achieved that when the installation bracket tilts toward the outside of the cabinet, the limiting rod will abut against the inner wall of the limiting slide groove, thereby providing support for the upper end of the installation bracket to prevent the installation bracket from tilting, making it safer and more convenient for the staff to pull the installation bracket. The setting of the limiting rod also prevents the installation bracket from completely detaching from the cabinet due to excessive force exerted by the staff, thereby preventing the installation bracket from completely detaching from the cabinet due to excessive force exerted by the staff and requiring reinstallation.

[0025] By setting up the fixed plug strip and the fixed structure, the staff can push the installation bracket to the deepest part of the cabinet after the inspection is completed, and then press the plug strip to make the plug strip press the clamping spring to retract into the storage port, and plug the fixed plug strip into the slide rail to abut the moving wheel. At this time, the plug strip is no longer pressed, so that the clamping spring pushes the plug strip into the plug port, thereby fixing the fixed plug strip, so that the fixed plug strip will not be displaced due to the impact of the moving wheel, thereby improving the protective effect of the fixed plug strip.

[0026] By setting up the protective structure, the staff can install the control device on the mounting plate. If the staff pulls the mounting bracket to slide out of the cabinet, the wires will push the mounting plate to rotate, thereby preventing the wires from bending and improving the service life of the wires.

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Example, see Figure 1 - Figure 4 , an intelligent PLC control cabinet comprises a cabinet 1, a cabinet door 10 hingedly connected to one side of the cabinet 1, and a mounting bracket 11 installed inside the cabinet 1, a slide rail 12 is fixedly arranged on the bottom surface of the cabinet 1, and the slide rail 12 is arranged along the width direction of the cabinet 1, and a moving wheel 13 is rotatably arranged on the bottom surface of the mounting bracket 11, and the moving wheel 13 is located in the slide rail 12, and a limiting structure 2 is provided on the top surface of the cabinet 1 and the top surface of the mounting bracket 11 to prevent the mounting bracket 11 from tipping over, and the moving wheel 13 is provided with a plurality of front and rear ends of the mounting bracket 11, respectively, and the limiting structure 2 comprises a limiting rod 20 fixedly arranged on the top surface of the mounting bracket 11 and a limiting slide groove 21 opened on the top surface of the cabinet 1, and the limiting slide groove 21 is arranged along the width direction of the cabinet 1 and its length is less than the width of the cabinet 1, and the limiting rod 20 is arranged on a side of the mounting bracket 11 close to the back of the cabinet 1, and the limiting rod 20 extends into the limiting slide groove 21.

[0031] When the staff needs to repair the electrical components inside the cabinet 1, the staff can pull the mounting bracket 11 so that the mounting bracket 11 slides out of the cabinet 1 along the slide rail 12, so that the staff can easily repair the electrical components on the mounting bracket 11. The setting of the slide rail 12 makes it more convenient for the staff to install the mounting bracket 11 inside the cabinet 1. The staff can first install the electrical components on the mounting bracket 11 outside the cabinet 1, and then install the mounting bracket 11 inside the cabinet 1 through the slide rail 12, making it more convenient for the staff to install the mounting bracket 11.

[0032] Although the provision of the slide rail 12 and the moving wheel 13 enables the staff to more conveniently repair the electrical components on the mounting bracket 11, it also causes the moving wheel 13 at the front end to be out of the track while the moving wheel 13 at the rear end is still stuck in the track when the staff pulls the mounting bracket 11 to slide out of the cabinet 1. This causes the mounting bracket 11 as a whole to have a tendency to tip over toward the outside of the cabinet 1. If the staff does not pay attention to holding the mounting bracket 11, it may be hit by the mounting bracket 11, which is very dangerous. The provision of the limiting structure 2 solves this technical problem. Through the provision of the limiting structure 2, when the mounting bracket 11 tips over toward the outside of the cabinet 1, the limiting rod 20 will abut against the inner wall of the limiting slide groove 21, thereby providing support for the upper end of the mounting bracket 11 to prevent the mounting bracket 11 from tipping over, making it safer and more convenient for the staff to pull the mounting bracket 11. The provision of the limiting rod 20 also prevents the mounting bracket 11 from completely detaching from the cabinet 1 due to excessive force by the staff, and can prevent the mounting bracket 11 from completely detaching from the cabinet 1 due to excessive force by the staff and requiring reinstallation.

[0033] Although the setting of the limiting structure 2 makes it safer and more convenient for the staff to pull the installation bracket 11, after the staff pushes the installation bracket 11 to the deepest part of the cabinet 1 and closes the cabinet door 10, the installation bracket 11 still has a certain sliding space. This means that if the cabinet 1 is subjected to vibration, the installation bracket 11 will slide inside the cabinet 1 and hit the cabinet door 10 or the deepest surface of the cabinet 1, causing damage to the electrical components or the control devices on the cabinet door 10. In order to solve this technical problem, in this embodiment, the slide rail 12 is provided with a fixed plug strip 3, which is used to block the slide rail 12 to prevent the installation bracket 11 from sliding along the slide rail 12. After the maintenance is completed and the installation bracket 11 is pushed to the deepest part of the cabinet 1, the fixed plug strip 3 is inserted into the slide rail 12 to abut against the moving wheel 13, thereby preventing the installation bracket 11 from moving along the slide rail 12 due to vibration.

[0034] Although the setting of the fixed plug strip 3 can prevent the mounting bracket 11 from moving along the slide rail 12 due to vibration, the moving wheel 13 will always hit the fixed plug strip 3 during the vibration process. This impact may cause the fixed plug strip 3 to move, causing the mounting bracket 11 to move and hit again. In order to solve this technical problem, refer to Figure 5In this embodiment, an insertion port 14 is provided at one end of the slide rail 12 away from the deepest part of the cabinet 1. The insertion port 14 is located on both sides of the interior of the slide rail 12. A fixing structure 4 for fixing the fixing plug strip 3 through the insertion port 14 is provided at one end of the fixing plug strip 3 away from the deepest part of the cabinet 1. The fixing structure 4 includes storage ports 40 that are not connected to each other and are provided on both sides of the fixing plug strip 3, a plug strip 41 plugged into the storage port 40, and a clamping spring 42 located between the inner wall of the storage port 40 and the end face of the plug strip 41. One end of the clamping spring 42 is fixedly connected to the end of the plug strip 41 plugged into the storage port 40. The staff completes the inspection and pushes the mounting bracket 11 to the deepest part of the cabinet 1, and then presses the plug strip 41 to make the plug strip 41 retract into the storage opening 40 against the snap-in spring 42, and plugs the fixed plug strip 3 into the slide rail 12 to abut against the moving wheel 13. At this time, the plug strip 41 is no longer pressed, so that the snap-in spring 42 pushes the plug strip 41 into the plug port 14, thereby fixing the fixed plug strip 3, so that the fixed plug strip 3 will not be displaced due to the impact of the moving wheel 13, thereby improving the protective effect of the fixed plug strip 3.

[0035] Although the setting of the fixing structure 4 improves the protective effect of the fixing plug strip 3, when the staff needs to slide the installation bracket 11 out of the cabinet 1, they need to first pull the plug strip 41 into the storage opening 40 before pulling out the fixing plug strip 3, but the plug strip 41 extending into the plug port 14 is difficult to pull, which makes it more troublesome for the staff to pull out the fixing plug strip 3. In order to solve this technical problem, in this embodiment, the storage opening 40 opens the end face of the fixing plug strip 3 away from the back side of the cabinet 1, and the end of the plug strip 41 close to the clamping spring 42 extends in the direction of the fixing plug strip 3 away from the back side of the cabinet 1. When the staff needs to pull out the fixing plug strip 3 and the installation bracket 11 can slide, by pinching the auxiliary handles 43 on the two plug strips 41 close to each other, the plug strip 41 compresses the clamping spring 42 and retracts it into the storage opening 40, so that the fixing plug strip 3 can be pulled out, making it more convenient for the staff to slide the installation bracket 11.

[0036] Although the provision of the slide rail 12 and the moving wheel 13 enables the staff to more conveniently repair the electrical components on the mounting bracket 11, each time the staff pulls the mounting bracket 11 to slide out of the cabinet 1, the wires connected to the control device will swing with the control device as the base point. This swing will cause creases to appear at the position where the wires are connected to the control device, causing the wires to wear. In order to solve this technical problem, in this embodiment, a protective structure 5 for reducing the wire loss of the control device is provided on the cabinet door 10. The protective structure 5 includes a connecting port opened on the cabinet door 10 and passing through the cabinet door 10, a rotating shaft 50 passing through the cabinet door 10 through the connecting port, and a mounting plate 51 fixedly connected to the rotating shaft. The movable shaft 50 is rotatably connected to the cabinet 1, and the mounting plate 51 is fixedly connected to one end of the rotating shaft 50 close to the mounting bracket 11. The staff installs the control device on the mounting plate 51. If the staff pulls the mounting bracket 11 to slide out of the cabinet 1, the wires will push the mounting plate 51 to rotate, thereby preventing the wires from bending and improving the service life of the wires. The rotating shaft 50 is hollow inside and has through openings 52 at both ends. The through openings 52 pass through the rotating shaft 50 and the mounting plate 51. Before the control device is installed on the mounting plate 51, the connecting wires of the components of the control device installed outside the cabinet door 10 can pass through the cabinet door 10 through the through openings 52, making it more convenient for the staff to install the control device.

[0037] Although the provision of the through opening 52 makes it more convenient for the staff to install the control device, when the mounting plate 51 rotates, the connecting wires of the components located outside the cabinet door 10 of the control device will be subjected to torque force, resulting in loss of the connecting wires. In order to solve this technical problem, in this embodiment, the end of the rotating shaft 50 away from the mounting plate 51 extends out of the cabinet door 10 and is provided with an external thread, and the end of the rotating shaft 50 provided with the external thread is threadedly connected with an auxiliary plate 53. The staff installs the main component of the control device in front of the mounting plate 51, passes the connecting wires through the cabinet door 10 through the through opening 52, and then installs the main component of the control device on the mounting plate 51, and then screws the auxiliary plate 53 on the outside of the cabinet door 10 to install the components of the control device on the auxiliary plate 53. In this way, when the main component of the control device rotates, the components of the control device will also rotate, thereby preventing loss of the connecting wires, and the cabinet door 10 can be clamped by the cooperation of the auxiliary plate 53 and the mounting plate 51 to prevent the entire protective component from falling off.

[0038] Specific implementation process: When assembling the entire control cabinet, first install the electrical components on the mounting bracket 11, then insert the rotating shaft 50 on the cabinet door 10, screw on the auxiliary plate 53 from the end of the rotating shaft 50 away from the mounting plate 51, then align the moving wheel 13 of the mounting bracket 11 with the slide rail 12, install the mounting bracket 11 in the cabinet body 1, then install the main components of the control device on the mounting plate 51, install the secondary components of the control device on the auxiliary plate 53, then connect the wires of the electrical components to the main components of the control device, then press the plug strip 41 into the storage port 40, and then plug the slide rail 12 with the fixed plug strip 3, loosen the plug strip 41 so that it extends into the plug port 14 to fix the fixed plug strip 3, and complete the installation.

[0039] When it is necessary to repair an electrical component, pinch the auxiliary handles 43 on the two plug strips 41 and bring them close to each other, so that the plug strip 41 compresses the clamping spring 42 and retracts it into the receiving opening 40, pull out the fixed plug strip 3, and then pull the mounting bracket 11 to slide out of the cabinet 1, and then repair the electrical component.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
