Description

Technical Field

[0001] This utility model relates to the field of switch cabinet processing technology, specifically a lifting device structure for switch cabinet processing. Background Technology

[0002] A switchgear is an electrical device primarily used for the reception, distribution, and control of electrical energy in a power system. It is typically assembled from primary and secondary equipment, including components such as circuit breakers, disconnectors, load switches, operating mechanisms, instrument transformers, and various protective devices. A switchgear refers to a complete set of power distribution equipment assembled from primary and secondary equipment according to a specific scheme. It is mainly used to control and protect lines and equipment. It can open, close, control, and protect electrical equipment during the power system's generation, transmission, distribution, and energy conversion processes. Due to the large size of switchgear, lifting structures are needed during production to raise it for subsequent processing. To improve processing efficiency, a lifting structure is required; however, existing lifting structures still have the following shortcomings:

[0003] When using existing lifting device structures, most of them are not convenient to adapt to the size of the switchgear and quickly adjust the lifting device spacing, which limits their use. At the same time, there are certain safety hazards in the switchgear manufacturing process, resulting in a decrease in the practicality and efficiency of the lifting device structure.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a lifting structure for switch cabinet processing. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting structure for switch cabinet processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting device structure for switchgear processing, comprising a receiving frame and an adjusting assembly. A lifting arm is provided at the upper center of the receiving frame, and adjusting assemblies are provided on both outer sides of the receiving frame. Each adjusting assembly includes a mounting plate, a limiting frame, a servo motor, a lead screw, a movable slider, a receiving plate, limiting through holes, and limiting crossbars. A limiting frame is installed at the inner center of the mounting plate, and a servo motor is installed at the outer end of the limiting frame. A lead screw is connected to the front end of the servo motor, and a movable slider is provided outside the lead screw. A receiving plate is installed at the lower end of the movable slider, and limiting through holes are opened at both ends inside the receiving plate. Limiting crossbars are connected inside the limiting through holes, and limiting assemblies are provided on both sides of the lower end of the receiving plate.

[0007] Furthermore, the limiting frame is perpendicular to the mounting plate, and the limiting frame is fixedly connected to the mounting plate by bolts.

[0008] Furthermore, the external dimensions of the movable slider are adapted to the internal dimensions of the limiting frame, and the movable slider is slidably connected to the limiting frame via a lead screw.

[0009] Furthermore, the internal dimensions of the limiting through hole are adapted to the external dimensions of the limiting crossbar, and the limiting crossbar is embeddedly connected to the receiving plate through the limiting through hole.

[0010] Furthermore, the limiting component includes a fixing block, a drive motor, and a take-up roller. The drive motor is mounted on the outside of the fixing block, and the front end of the drive motor is connected to the take-up roller.

[0011] Furthermore, the limiting assembly also includes a steel cable, a limiting component, and an anti-slip rubber pad. A steel cable is provided on the outside of the winding roller, and a limiting component is installed at the front end of the steel cable. An anti-slip rubber pad is added to the inner side of the limiting component.

[0012] Furthermore, the take-up roller is confined between two fixed blocks, and the take-up roller is rotatably connected to the fixed blocks via a drive motor.

[0013] Furthermore, the number of the limiting members is set to four, and two of the limiting members form a group, and each group of the limiting members is symmetrically arranged on both sides of the lower end of the receiving frame with respect to the side center axis of the receiving frame.

[0014] This utility model provides a lifting fixture structure for switch cabinet processing, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the adjustment component, enables the lifting fixture structure used in switchgear processing to rotate the lead screw driven by the servo motor at the outer end of the limit frame during use. This causes the movable slider connected to the outside of the lead screw to move accordingly, thereby adjusting the position of the receiving plate installed at the lower end of the movable slider. This allows it to adapt to the use spacing of the lifting fixture for switchgear of different sizes. The use of the limit through hole in conjunction with the limit crossbar increases the stability of the receiving plate during movement, thereby preventing positional deviation of the receiving plate during movement, improving the stability of the switchgear during hoisting, and increasing the overall practicality and efficiency of the lifting fixture structure.

[0016] 2. This utility model, through the setting of the limiting component, enables the fixing block to be fixedly installed on both sides of the lower end of the receiving plate by fastening bolts when using the lifting structure for switchgear processing. The drive motor on the outside of the fixing block drives the winding roller to rotate, so that the steel cable connected to the outside of the winding roller is wound up. This allows for the adjustment of the steel cable length to adapt to the size of the switchgear. The limiting component is fixedly installed at the front end of the steel cable to limit the external position of the switchgear. With the help of anti-slip rubber pads, it prevents the switchgear from loosening after being locked and limited. This allows for quick lifting of the switchgear, improving the overall practicality and efficiency of the lifting structure. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 2As shown, a lifting device structure for switchgear processing includes a receiving frame 1 and an adjusting assembly 3. A lifting arm 2 is located at the upper center of the receiving frame 1, and adjusting assemblies 3 are located on both outer sides of the receiving frame 1. Each adjusting assembly 3 includes a mounting plate 301, a limiting frame 302, a servo motor 303, a lead screw 304, a movable slider 305, a receiving plate 306, a limiting through hole 307, and a limiting crossbar 308. The limiting frame 302 is installed at the inner center of the mounting plate 301, and the servo motor 303 is installed at the outer end of the limiting frame 302. The lead screw 304 is connected to the front end of the servo motor 303. Meanwhile, a movable slider 305 is provided on the outside of the lead screw 304. A receiving plate 306 is installed at the lower end of the movable slider 305, and limit through holes 307 are opened at both ends inside the receiving plate 306. A limit crossbar 308 is connected inside the limit through holes 307. The limit frame 302 is perpendicular to the mounting plate 301, and the limit frame 302 is fixedly connected to the mounting plate 301 by bolts. The external dimensions of the movable slider 305 are adapted to the internal dimensions of the limit frame 302, and the movable slider 305 is slidably connected to the limit frame 302 through the lead screw 304. The internal dimensions of the limit through holes 307 are... The external dimensions of the limiting crossbar 308 are adapted to the limiting crossbar 308, and the limiting crossbar 308 is embeddedly connected to the receiving plate 306 through the limiting through hole 307. The limiting frame 302 is fixedly installed on both sides of the outside of the receiving frame 1 by fastening bolts, and the mounting plate 301 is fixedly installed on the outside of the limiting frame 302 with fastening bolts. The servo motor 303 is fixedly installed on the outer end of the limiting frame 302. The output shaft of the servo motor 303 is connected to the lead screw 304 through a coupling. The operation of the servo motor 303 drives the lead screw 304 to rotate, so that the movable slider 305 connected to the outside of the lead screw 304 moves accordingly. The sliding position moves, thereby adjusting the position of the receiving plate 306 installed at the lower end of the movable slider 305. This allows it to adapt to the spacing of the lifting device for switchgear of different sizes. The internal dimensions of the limiting through holes 307 at both ends of the receiving plate 306 are matched with the external dimensions of the limiting crossbar 308. The limiting through holes 307 and the limiting crossbar 308 increase the stability of the receiving plate 306 during movement, thereby preventing the position of the receiving plate 306 from shifting during movement, improving the stability of the switchgear during hoisting, and increasing the overall practicality and efficiency of the lifting device structure.

[0023] like Figure 1 and Figure 3As shown, limit components 4 are provided on both sides of the lower end of the receiving plate 306. The limit components 4 include a fixing block 401, a drive motor 402, and a take-up roller 403. The drive motor 402 is installed on the outside of the fixing block 401, and the front end of the drive motor 402 is connected to the take-up roller 403. The limit components 4 also include a steel cable 404, a limit member 405, and an anti-slip rubber pad 406. The steel cable 404 is provided on the outside of the take-up roller 403, and the limit member 405 is installed on the front end of the steel cable 404. An anti-slip rubber pad 406 is added to the inner side of the limit member 405. The take-up roller 403 is restricted between two fixing blocks 401, and the take-up roller 403 is rotatably connected to the fixing block 401 through the drive motor 402. The number of limit members 405 is four, and two limit members 405 form a group. Each group of limit members 405 is positioned on the side of the receiving frame 1. The central axis is symmetrically arranged on both sides of the lower end of the support frame 1. The fixing block 401 is fixedly installed on both sides of the lower end of the support plate 306 by fastening bolts. The drive motor 402 is fixedly installed on the middle of the outer side of the fixing block 401 with fastening bolts. The output shaft of the drive motor 402 is connected to the winding roller 403 through a coupling. The operation of the drive motor 402 drives the winding roller 403 to rotate, so that the steel cable 404 connected to the outside of the winding roller 403 is wound up. This allows the length of the steel cable 404 to be adjusted according to the size of the switch cabinet. The limiting member 405 is fixedly installed at the front end of the steel cable 404. The limiting member 405 is used to limit the outside of the switch cabinet. With the help of the anti-slip rubber pad 406, it is prevented from loosening after the limit is engaged. This allows for quick hoisting of the switch cabinet and improves the overall practicality and efficiency of the hoisting structure.

[0024] In summary, the lifting device structure used for switchgear processing, when in use, firstly, the lifting arm 2 is fixedly installed on the upper middle part of the receiving frame 1 using fastening bolts. The lifting arm 2 facilitates the position movement and adjustment of the receiving frame 1. The servo motor 303 on the outside of the limit frame 302 drives the lead screw 304 to rotate, causing the movable slider 305 connected to the lead screw 304 to move accordingly. This allows the receiving plate 306 installed at the lower end of the movable slider 305 to adjust its position, thus adapting to the use spacing of the lifting device for switchgear of different sizes. The limit through hole 307, in conjunction with the limit crossbar 308, increases the stability of the receiving plate 306 during movement, thereby avoiding damage. When the receiving plate 306 moves, its position shifts. Then, the fixing block 401 is fixedly installed on both sides of the lower end of the receiving plate 306 by fastening bolts. The drive motor 402 on the outside of the fixing block 401 drives the winding roller 403 to rotate, so that the steel cable 404 connected to the outside of the winding roller 403 is wound up. This allows the length of the steel cable 404 to be adjusted to fit the size of the switch cabinet. The limiting member 405 is fixedly installed at the front end of the steel cable 404. The limiting member 405 limits the outside of the switch cabinet and, together with the anti-slip rubber pad 406, prevents the switch cabinet from loosening after being locked. This allows for quick hoisting of the switch cabinet and improves the overall practicality and efficiency of the hoisting device structure.
