AI Technical Summary

Technical Problem

During the assembly process of high-end transformers, the lifting platform tilts, collapses or falls due to wear of the turbine inner wire master, which poses safety hazards.

Method used

A mounting frame lifting platform anti-fall detection wire feed device is designed. By installing a safety wire feeder and a limit switch on the lifting platform, the distance between the turbine inner wire feeder and the safety wire feeder is detected. When the turbine inner wire feeder is worn, the safety wire feeder replaces its load-bearing, and the alarm is triggered and the lifting motor is stopped through the limit switch to prevent the platform from falling.

Benefits of technology

It effectively avoids the tilt, collapse or fall of the platform caused by wear of the turbine inner wire feeder, ensures the safety of production operations, and prevents loss of personnel and property.

Description

Technical Field

[0001] The utility model relates to an anti-falling detection screw nut device for an assembly rack lifting platform, belonging to the technical field of work platform safety protection. Background Technique

[0002] When producing high-end transformers with high voltage levels and large capacities, an assembly rack is required for the sleeve assembly of the transformer. Sometimes materials are also placed on the lifting platform of the assembly rack. The internal screw nuts of the turbines on both sides of the lifting platform may be worn after long-term use, which may cause the platform to tilt, collapse, or fall. To solve the above problems, there is an urgent need in this field to design an anti-falling detection device for an assembly rack lifting platform. Content of the Utility Model

[0003] The purpose of the utility model is to provide an anti-falling detection screw nut device for an assembly rack lifting platform, which installs an anti-falling safety screw nut device on the lifting platform to avoid the platform from falling due to the failure of the lifting system during production operations, and solve the above problems existing in the background technique.

[0004] The technical solution of the utility model is as follows:

[0005] An anti-falling detection screw nut device for an assembly rack lifting platform includes a lifting platform, columns, lead screws, and turbines. The two sides of the lifting platform are respectively fixedly connected to the corresponding turbines (Is the turbine directly connected to the lifting platform? If not, please specifically describe how the turbine is connected to the lifting platform). The internal screw nut of the turbine is threadedly connected to the longitudinally arranged lead screw. The lifting motor drives the lead screw to rotate, and drives the lifting platform to move up and down through the turbine. A safety screw nut is installed at the bottom of each turbine. The safety screw nut is threadedly connected to the lead screw. The safety screw nut and the turbine move up and down along the lead screw together. The lead screw is located inside the column. A limit switch is provided on the outer side of the adjacent end of the safety screw nut and the turbine. The limit switch is used to detect the distance between the safety screw nut and the internal screw nut of the turbine. The limit switch is connected to the alarm indicating device and the lifting motor in the control cabinet of the lifting platform.

[0006] Further, the flange one at the top of the safety screw nut is connected to the flange two at the bottom of the turbine by bolts.

[0007] Further, the outer diameter of the turbine is greater than the outer diameter of the safety screw nut.

[0008] The lifting platform, lead screw, turbine, and limit switch are equipment well-known and commonly used in this field.

[0009] The positive effect of the utility model: Installing a safety screw nut and a limit switch on the lifting platform can avoid the platform from tilting, collapsing, or falling due to the wear of the internal screw nut of the turbine during production operations, resulting in personnel and property losses. Description of the Drawings

[0010] Figure 1 Structural schematic diagram of the present utility model;

[0011] In the figure: lifting platform 1, column 2, lead screw 3, turbine 4, safety nut 5, limit switch 6. Specific implementation manner

[0012] A fall prevention detection nut device for an assembly rack lifting platform, comprising a lifting platform 1, a column 2, a lead screw 3 and a turbine 4. The two sides of the lifting platform 1 are respectively connected to the corresponding turbines 4. The internal thread of the turbine 4 is threadedly connected to the longitudinally arranged lead screw 3. The lifting motor drives the lead screw 3 to rotate, and drives the lifting platform 1 to move up and down through the turbine 4. A safety nut 5 is installed at the bottom of each turbine 4. The safety nut 5 is threadedly connected to the lead screw 3. The safety nut 5 and the turbine 4 move up and down along the lead screw 3 together. The lead screw 3 is located inside the column 2. A limit switch 6 is arranged on the outer side of the adjacent end of the safety nut 5 and the turbine 4. The limit switch 6 is used to detect the distance between the safety nut 5 and the turbine 4. The limit switch 6 is connected to the alarm indicating device and the lifting motor in the control cabinet of the lifting platform.

[0013] Further, the flange 1 at the top of the safety nut 5 is connected to the flange 2 at the bottom of the turbine 4 by bolts.

[0014] Further, the outer diameter of the turbine 4 is larger than the outer diameter of the safety nut 5.

[0015] In this embodiment, lead screws 3 are arranged inside the two columns on the left and right sides of the lifting platform 1, and a safety nut 5 is installed at the bottom of the original turbine 4 on the lead screw 3. A limit switch 6 is installed on the safety nut 5 to detect the gap between the internal thread of the turbine 4 and the safety nut 5. After the internal thread of the turbine 4 is damaged, the safety nut 5 can replace it to bear the weight and play a protective role. When the internal thread of the turbine 4 is damaged and the turbine 4 moves down to the position of the limit switch 6 of the safety nut 5, the limit switch 6 is turned on. At this time, the alarm indicating device in the control cabinet of the lifting platform starts to alarm, and at the same time the lifting motor stops working to prevent the lifting platform 1 from falling.
