AI Technical Summary

Technical Problem

The control boxes of the existing mine hoisting signal system cannot effectively isolate moisture when used in the mine, resulting in moisture damage to the box body. Furthermore, the wiring harness cannot be effectively arranged and adjusted, increasing the operation time and difficulty for the staff.

Method used

A mid-section control box for a mine hoisting signal system was designed, which includes a liftable cable tray, a rainproof vent, a cable routing port, a support base, a cable tray port, a marking sticker, and an adjustable height cable tray. These structures enable the classification, placement, limiting, and marking of cable bundles, preventing moisture from entering and simplifying operation.

Benefits of technology

It effectively isolates moisture, protects the instruments inside the enclosure, simplifies the wiring harness adjustment process, improves operational efficiency, reduces damage to the instruments caused by the wiring harness, and facilitates subsequent adjustments and maintenance.

Abstract

The utility model discloses a middle section control box for a mine hoisting signal system, which belongs to the technical field of control boxes, and comprises a box body, the top of the box body is connected with a top plate, one side of the front surface of the box body is provided with two hinges, and the box body is connected with a box door through the two hinges; and the box body is internally provided with a wire bunching frame capable of ascending and descending. The device has the beneficial effects that by arranging the supporting seat, when the box body is placed and used, the installation positions are conveniently separated, so that moisture is isolated, by arranging the wire bunching frame, the wire bunching opening, the pressing plate, the tension spring and the like, wire harnesses used by instruments in the box body are conveniently classified and placed, the wire harnesses are pressed and limited, and the wire harnesses are prevented from being damaged. According to the wire bunching rack, the wire bunching rack is arranged, the situation that an instrument is pulled due to the gravity of the wire bunches is avoided, the classified wire bunches are marked through the marking stickers, follow-up adjustment of workers is facilitated, and the height of the wire bunching rack is conveniently adjusted through the bearing seats, the rotating shafts and the stretching belts.
