Description
Technical Field
[0001] This utility model relates to the field of control cabinet technology, specifically a control cabinet with a lifting device. Background Technology
[0002] In fields such as industrial control and electrical equipment installation, control cabinets serve as the core carrier for housing electrical components and control modules. Their structural design directly affects the ease of installation and maintenance, space utilization, and operational stability of the equipment. Currently, most control cabinets on the market adopt a fixed frame structure, mainly consisting of a base, a fixed outer frame, a door panel, and an internal fixed mounting plate. Electrical components are usually directly fixed to the internal mounting plate or the inner wall of the cabinet.
[0003] However, existing control cabinets have certain structural limitations: When it is necessary to install or maintain electrical components at different heights, workers need to use ladders, scaffolding and other auxiliary tools, which is not only cumbersome to operate, but also poses safety hazards for working at heights. The cabinet's internal space is divided into fixed layers, making it impossible to flexibly adjust the installation height according to the size and quantity of components. This results in low space utilization and makes it difficult to install some large components or multiple sets of components. If the position of the component needs to be adjusted after installation, it must be disassembled and re-fixed, which is costly and inefficient and cannot meet the needs of rapid debugging or modification. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a control cabinet with a lifting device.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A control cabinet with a lifting device is characterized in that it includes: a control cabinet base, outer frame assemblies symmetrically arranged on the front and rear sides of the top of the control cabinet base, a rear door panel connected to the left side of the outer frame assemblies on the front and rear sides by bolts, a top plate arranged on the top of the outer frame assemblies, two sets of servo motors arranged on the left side of the top plate, a lead screw fixedly arranged on the rotating shaft of the servo motor, the bottom of the lead screw connected to the bearing of the control cabinet base, a movable plate movably arranged on the lead screw, and an inner frame assembly fixedly arranged on the control cabinet base between the outer frame assemblies on the front and rear sides by bolts. The servo motors are used to start rotating the lead screws, and the lead screws drive the movable plate to move up and down. A sheet metal curved plate is provided on the side of the movable plate near the rear door panel. A pressing fastener is provided at the connection between the sheet metal curved plate and the movable plate. The pressing fastener is used to make the movable plate pop out after pressing the sheet metal curved plate. Pressing it again at a certain position will lock the movable plate and the sheet metal curved plate back in place. Two sets of threaded blocks are provided on the top of the sheet metal curved plate. The threaded blocks are engaged with the screw thread. The outer frame assembly is used to support the control cabinet. The inner frame assembly is used to classify the lifting and lowering of the movable plate. When a certain level is reached, the movable plate is moved away from the rear door panel.
[0006] Preferably, the inner frame assembly includes: a support vertical plate, the support vertical plate is set at the top four corners of the control cabinet base, the left and right sets of support vertical plates on the front and rear sides are symmetrically arranged, and multiple sets of sheet metal horizontal plates are fixed between the support vertical plates on the left and right sides from top to bottom by bolts, and the inner side of the sheet metal horizontal plate is provided with a long groove. The bottom of the movable plate is equipped with multiple sets of limit rods. The limit rods are telescopic and are used to extend in advance when the movable plate needs to pop out when it moves to the sheet metal horizontal plate. The limit rods cooperate with the long groove to realize the left and right movement of the movable plate on the long groove.
[0007] Preferably, the outer frame assembly includes: a support frame plate, with the front and rear support frame plates fixedly mounted on the front and rear sides of the top of the control cabinet base by bolts; the top and middle of the support frame plate are respectively provided with a connecting beam one and a connecting beam two, both of which are used to connect and fix the support frame plate.
[0008] Compared with the prior art, the present invention provides a control cabinet with a lifting device, which has the following advantages: The inner frame assembly fixes multiple sheet metal horizontal plates through the support vertical plates to form a hierarchical structure from top to bottom. The lifting level can be preset according to the installation requirements of electrical components, so that the moving plate can accurately stop at the target level under the drive of the servo motor, without the need for repeated manual adjustment of positioning, thus improving installation and debugging efficiency. The long groove on the inner side of the sheet metal horizontal plate can cooperate with the telescopic limit rod at the bottom of the movable plate. When the movable plate reaches the target level, the limit rod extends and embeds into the groove, allowing the staff to move the movable plate directly to the side away from the rear door panel without having to go deep into the cabinet to operate the components, greatly reducing the difficulty of maintenance. The support vertical plates are set at the four corners of the control cabinet base, together with multiple sets of sheet metal horizontal plates, to form an internal partition support structure. This not only prevents the moving plates from swaying when raised and lowered, but also provides auxiliary support for the components inside the cabinet, thereby improving the overall structure's impact resistance.
[0009] The outer frame assembly consists of a support frame plate, a connecting beam one, and a connecting beam two. The beams are fixedly connected to the support frame plate with bolts, forming a three-dimensional support structure with upper and lower double beams and support frame plates on both sides. This structure can effectively distribute the weight of the moving plate and components during the lifting process and prevent the cabinet from deforming due to uneven stress. The outer frame encloses the core components inside the cabinet, preventing external dust and impurities from entering. It also provides a stable mounting base for lifting components such as servo motors and lead screws, ensuring the long-term stable operation of the lifting device. Attached Figure Description

[0012] 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.
[0013] Reference Figures 1-4 As shown, a control cabinet with a lifting device in this embodiment includes a control cabinet base 2. The control cabinet base 2 serves as the supporting foundation for the entire equipment, providing stable support for all components above it. The top front and rear sides of the control cabinet base 2 are symmetrically provided with outer frame components 1. A rear door panel is bolted to the left side of the outer frame components 1 on both sides. The bolted connection facilitates the disassembly and assembly of the rear door panel, allowing for quick access to the internal components during subsequent maintenance.
[0014] The top of the outer frame assembly 1 is provided with a top plate 4, and two sets of servo motors 401 are provided on the left side of the top plate 4. The presence of the servo motors 401 provides precise power support for the lifting and lowering of the moving plate 5. A lead screw 402 is fixedly installed on the rotating shaft of the servo motor 401. This fixed connection method ensures that the servo motor 401 can synchronously drive the lead screw 402 to rotate when it starts. The bottom of the lead screw 402 is connected to the bearing of the control cabinet base 2. The bearing connection can reduce the frictional resistance when the lead screw 402 rotates, ensuring smooth lifting and lowering.
[0015] A movable plate 5 is movably mounted on the lead screw 402. A sheet metal curved plate is mounted on the side of the movable plate 5 near the rear door panel. A press fastener is provided at the connection between the sheet metal curved plate and the movable plate 5. The press fastener can be pressed to pop out and then pressed to lock, which facilitates the flexible separation and fixation of the movable plate 5 and the sheet metal curved plate. Two sets of threaded blocks 501 are provided on the top of the sheet metal curved plate. The threaded blocks 501 are threadedly engaged with the lead screw 402. This engagement method can convert the rotational motion of the lead screw 402 into the linear lifting motion of the movable plate 5.
[0016] An inner frame assembly 3 is bolted to the control cabinet base 2 between the outer frame assemblies 1 on both the front and rear sides. The bolt fixing ensures that the inner frame assembly 3 is installed firmly and is not easily displaced by the raising and lowering of the moving plate 5. The inner frame assembly 3 includes a support vertical plate 301 and a sheet metal horizontal plate 302. The support vertical plate 301 is located at the four corners of the top of the control cabinet base 2. Multiple sets of sheet metal horizontal plates 302 are bolted between the support vertical plates 301 on the left and right sides from top to bottom. The inner side of the sheet metal horizontal plate 302 is provided with a long groove. Multiple sets of telescopic limit rods are provided at the bottom of the moving plate 5. The limit rods cooperate with the long grooves to allow the moving plate 5 to move left and right after reaching the target level, which can be operated without going deep into the cabinet.
[0017] In some examples, dustproof cotton is pasted on the inner side of the support frame plate 101 of the outer frame assembly 1. The dustproof cotton can prevent external dust from entering the cabinet, reduce the corrosion of dust on components such as the servo motor 401 and the lead screw 402, and extend the service life of the equipment.
[0018] In some examples, an adjusting bolt is provided at the connection between the sheet metal horizontal plate 302 of the inner frame assembly 3 and the supporting vertical plate 301. The adjusting bolt can finely adjust the height of the sheet metal horizontal plate 302 according to actual needs, so that the grading position of the movable plate 5 is more flexible and can be adapted to the installation of electrical components of different sizes.
[0019] The working principle of this utility model is as follows: Before using the control cabinet with lifting device, the basic structure must first be installed and fixed: the control cabinet base 2 is placed stably in the preset installation position, using its load-bearing characteristics to provide stable support for the overall equipment. Then, the outer frame assembly 1 is fixed to the front and rear sides of the top of the control cabinet base 2 by bolt connection. The support frame plate 101 in the outer frame assembly, together with the top connecting beam 102 and the middle connecting beam 203, form a three-dimensional support structure. The bolt connection method ensures the overall stability of the outer frame assembly 1 and provides a benchmark for the subsequent installation of components. Then, the inner frame assembly 3 is fixed to the control cabinet base 2 between the front and rear outer frame assemblies 1 by bolt. The support vertical plates 301 of the inner frame assembly are distributed at the four corners of the control cabinet base 2. Multiple sets of sheet metal horizontal plates 302 are fixed from top to bottom between the left and right support vertical plates 301 to form a preset lifting and tiered structure. After the overall frame is built, the rear door panel is installed on the left side of the outer frame assembly 1 by bolt, realizing the initial protection of the cabinet.
[0020] When electrical components need to be installed or adjusted, the two sets of servo motors 401 on the left side of the top plate 4 are started. The rotating shaft of the servo motor 401 drives the lead screw 402 fixed to it to rotate synchronously. Since the bottom of the lead screw 402 is connected to the control cabinet base 2 through the bearing, the rotational friction resistance can be greatly reduced, ensuring that the lead screw 402 rotates smoothly. The moving plate 5 forms a threaded engagement with the lead screw 402 through the threaded block 501 on the top of the sheet metal bent plate. The rotational motion of the lead screw 402 is converted into the linear lifting and lowering motion of the moving plate 5 along the axis of the lead screw 402. The staff can control the forward and reverse rotation of the servo motor 401 according to the component installation height requirements, and adjust the lifting direction and speed of the moving plate 5.
[0021] When the movable plate 5 needs to stay at a specific level, the hierarchical positioning function of the inner frame component 3 is activated. When the movable plate 5 approaches the sheet metal horizontal plate 302 of the target level, the telescopic limit rod at the bottom of the movable plate 5 is extended. When the movable plate 5 descends to the position where the limit rod is aligned with the long groove on the inner side of the sheet metal horizontal plate 302, the servo motor 401 stops running, and the limit rod is embedded in the long groove. This not only achieves stable stopping of the movable plate 5 at that level, but also provides guidance for the subsequent lateral movement of the movable plate 5. If it is necessary to operate the components on the movable plate 5 at this time, press the pressing fastener at the connection between the movable plate 5 and the sheet metal curved plate. After the fastener is unlocked, the movable plate 5 pops outward. The operator can pull the movable plate 5 away from the rear door panel along the direction of the long groove. The components can be operated conveniently without going deep into the cabinet, avoiding the problem of limited operating space in traditional control cabinets.
[0022] After the operation is completed, push the moving plate 5 back to its original position along the long groove, and press the fastener again to the designated position to re-lock the moving plate 5 with the sheet metal bending plate. If it is necessary to adjust the moving plate 5 to other levels, control the limit rod to retract, restart the servo motor 401 to drive the lead screw 402 to rotate, and drive the moving plate 5 to continue to rise and fall. Repeat the above-mentioned hierarchical positioning and operation process.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
