Abstract

The utility model discloses a self-absorption collision type safety door device, which comprises a door frame of a coal injection disk feeder, a safety door arranged at the door frame and a strong magnet arranged on the door frame, wherein the height between the strong magnet and the ground is not less than 50 cm; a through hole is formed in the center of the powerful magnet; a switch plate seat is adsorbed at the front end of the strong magnet; the switch plate seat and the door frame are fixed through bolts and nuts, and the bolts penetrate through the through holes; a limit switch is fixed on the switch plate seat, and a contact plate tightly attached to the limit switch is fixed on the safety door; the self-absorption collision type safety door device eliminates the potential safety hazard of electric shock caused by water splashing to the limit switch; the working efficiency is improved, and the working time is saved; the inconvenience that the baffle is broken back and forth when the safety door is opened and closed is reduced; in addition, the safety level of the whole safety door is greatly improved.

Description

Self-absorption collision type safety door device

Technical Field

The utility model relates to a safety door, in particular to a self-absorption collision type safety door device, and belongs to the technical field of safety protection of a coal injection disk feeder.

Background

Install spacing interlocking between coal injection disc feeder emergency exit and disc, the disc rotates the in-process, the emergency exit is opened, coal injection disc feeder chance automatic shutdown operation, but former spacing proximity switch mounted position is very close with ground, when wasing the platform, water spatters very easily and causes accidents such as limit switch electric leakage short circuit on 220V's the limit switch, spacing malfunctioning potential safety hazard, in addition, current coal injection disc feeder emergency exit is when the switch door, need make a round trip to break the baffle off with the fingers and thumb and fix, it is very inconvenient to operate.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a self-absorption collision type safety door device, wherein a limit switch is lifted to 50cm away from the ground and is matched with a powerful magnet for use; the safety door is provided with a stop which is attracted with the magnet when the door is closed, thereby realizing triggering of the safety interlocking device.

The self-absorption collision type safety door device comprises a door frame of a coal injection disc feeder, a safety door arranged at the door frame and a strong magnet arranged on the door frame, wherein the height between the strong magnet and the ground is not less than 50 cm; a through hole is formed in the center of the powerful magnet; a switch plate seat is adsorbed at the front end of the strong magnet; the switch plate seat and the door frame are fixed through bolts and nuts, and the bolts penetrate through the through holes; a limit switch is fixed on the switch plate seat, and a contact plate tightly attached to the limit switch is fixed on the safety door; the limit switch is linked with the coal injection disk feeder through a controller; when the testing device is used, the limit switch is lifted to 50 centimeters away from the ground and matched with a powerful magnet with the size of 50 × 60mm for use; welding a 40 x 100mm contact plate on the safety door; the contact plate is attracted with the magnet and triggers the contact limit switch; due to the attraction of the magnet, when the safety door is closed, the contact plate and the magnet are tightly adsorbed together, so that the safety interlocking device can be stably triggered; when the safety door is opened, the interlocking is disconnected, the disc stops running, and the whole safety door runs stably.

Furthermore, the contact plate is provided with a through hole in a manner of rightly aligning the bolt, so that the movement interference of the bolt to the contact plate is avoided, and in addition, the bolt can also adopt a counter bore installation mode.

Furthermore, an inner plate seat is welded on the inner edge of the door frame in a facing manner, and an infrared trigger is mounted on the inner plate seat in a facing manner; the infrared trigger is linked with the coal injection disk feeder through the controller, and when the limit switch fails, the infrared trigger serves as an internal second safety mechanism.

Compared with the prior art, the self-absorption collision type safety door device eliminates the potential safety hazard of electric shock caused by water splashing to the limit switch; the working efficiency is improved, and the working time is saved; the inconvenience that the baffle is broken back and forth when the safety door is opened and closed is reduced; in addition, the whole protection adopts active contact switch to carry out the outside protection, sets up the infrared trigger of passive trigger formula simultaneously in the emergency exit inboard, and both carry out safety monitoring separately, have improved the security level of whole emergency exit greatly.

Detailed Description

Example 1:

the self-absorption collision type safety door device shown in fig. 1 comprises a door frame 1 of a coal injection disk feeder, a safety door 2 arranged at the door frame and a strong magnet 3 arranged on the door frame, wherein the height between the strong magnet 3 and the ground is not lower than 50 cm; a through hole is formed in the center of the powerful magnet 3; a switch plate seat 4 is adsorbed at the front end of the strong magnet 3; the switch board seat 4 and the door frame 1 are fixed through a bolt 5 and a nut, and the bolt 5 penetrates through a through hole; a limit switch 6 is fixed on the switch plate seat 4, and a contact plate 7 tightly attached to the limit switch is fixed on the safety door 2; the limit switch 6 is linked with the coal injection disk feeder through a controller; when the testing device is used, the limit switch is lifted to 50 centimeters away from the ground and matched with a powerful magnet with the size of 50 × 60mm for use; welding a 40 x 100mm contact plate on the safety door; the contact plate is attracted with the magnet and triggers the contact limit switch; due to the attraction of the magnet, when the safety door is closed, the contact plate and the magnet are tightly adsorbed together, so that the safety interlocking device can be stably triggered; when the safety door is opened, the interlocking is disconnected, the disc stops running, and the whole safety door runs stably.

The contact plate 7 is provided with a through hole 71 opposite to the bolt, so that the movement interference of the bolt to the contact plate is avoided, and in addition, the bolt can also adopt a counter bore installation mode.

In still another embodiment, as shown in fig. 2, an inner plate seat is welded on the inner edge of the door frame 1, and an infrared trigger 8 is mounted on the inner plate seat; the infrared trigger 8 is linked with the coal injection disk feeder through a controller, and when the limit switch fails, the infrared trigger serves as an internal second safety mechanism.
