Abstract
The utility model discloses a kind of overhead door fall-proofing device, comprise pin, cylinder, cylinder pin and electromagnetic valve, wherein, described pin is located on overhead door fluctuating orbit, and pin is arranged at intervals with jack; Described cylinder is placed in overhead door top, and cylinder is elevated with overhead door, and cylinder is corresponding with pin position; Described cylinder pin is located in cylinder, and cylinder pin is pull-in in cylinder by electromagnetic valve.The utility model is by the position of electromagnetic valve and cylinder action master cylinder pin, and under powering-off state, cylinder pin can be inserted in jack at automatic spring under cylinder action, stops overhead door to fall, effectively reduces potential safety hazard.
Description
Technical field
The utility model relates to technical field of automation, is specifically related to a kind of overhead door fall-proofing device.
Background technology
Battery pole plates, after painting cream, also contains the free lead of 20-25% in lead plaster, and the moisture of 8-10%, in lead plaster, moisture is 8%, free lead, under the catalysis of water, can reach maximum oxidation rate, enter curing room and carry out cell panel solidification, moisture is finally controlled about 1%.
Conventional solidification drying room, its door is manual double door, needs manually to open, and can occupy channel position when door is opened, and takes time and effort; In order to improve the deficiency of manually operated door, my company newly devises electric overhead door to increase work efficiency.But because overhead door adopts electricity to control, in the course of the work once have a power failure or power-off, motor runs out of steam, and drying room door, losing under holdback force state and can falling fast, causes certain danger.
Utility model content
The purpose of this utility model is for the problem in background technology, provides a kind of overhead door fall-proofing device, overhead door can be made to be fixed on somewhere, can not fall fast under powering-off state, increases safety.
The utility model technical solution:
Overhead door fall-proofing device, is characterized in that: described device comprises pin, cylinder, cylinder pin and electromagnetic valve, and wherein, described pin is located on overhead door fluctuating orbit, and pin is arranged at intervals with jack; Described cylinder is placed in overhead door top, and cylinder is elevated with overhead door, and cylinder is corresponding with pin position; Described cylinder pin is located in cylinder, and cylinder pin is pull-in in cylinder by electromagnetic valve.
As preferably, described pin is equidistantly provided with jack.
Further, described pin is two, is separately positioned on overhead door both sides, and on two pins, jack position is corresponding, and corresponding pin position, overhead door top is respectively equipped with cylinder and is placed in the cylinder pin in cylinder.
The utility model beneficial effect:
The utility model is by the position of electromagnetic valve and cylinder action master cylinder pin, and under powering-off state, cylinder pin can be inserted in jack at automatic spring under cylinder action, stops overhead door to fall, effectively reduces potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 be the utility model pin and gas cylinder working condition time a left side look cross-sectional schematic.
Detailed description of the invention
The utility model is specifically described below in conjunction with drawings and Examples.
As shown in Figure 1, solidification drying room, comprises overhead door 1, and overhead door controls lifting under chain 2, reductor 3, motor effect, and fluctuating orbit is provided with pin 4, pin 4 points is located at overhead door both sides, and on pin, correspondence is equidistant is provided with jack 5; On both sides, overhead door top, corresponding pin position is separately installed with cylinder 6, cylinder built with cylinder pin 7, cylinder pin and electromagnetic valve UNICOM.
Specific works process:
As shown in Figure 2, in energising situation, cylinder pin is pull-in in cylinder 6 by electromagnetic valve, and cylinder is elevated with overhead door, when unexpected power-off, cylinder pin 7 loses the suction-combining force, ejects under cylinder impetus, be inserted in pin jack 5, overhead door is fixed, can effectively stop falling of overhead door.
To sum up, the utility model produces a desired effect.
