Abstract
The utility model discloses a protective door interlock protection device for material hoist discharging platform. The protective door protection device is composed of a left protective door, a right protective door and a bolt, the left protective door is mounted on a left upright by a left upper hinge and a left lower hinge, the right protective door is mounted on a right upright by a right upper hinge and a right lower hinge, a guard switch is mounted on the left part of the bolt, and the tactile rod of the guard switch extrudes into the cylinder of the bolt. The utility model discloses a protective door interlock protection device for material hoist discharging platform, wherein indicator lights are one-to-one corresponding to the protective door, a windlass can't start normally when the protective door is not closed or not tightly closed, the driver of the windlass can know the layer position with unclosed protective door through the indicator light of the protective door in the windlass guarding shed; thereby, safe accidents due to unclosed protective doors or loosely-closed protective doors are avoided.
Description
Technical field
The utility model relates to a kind of safety device of building operation discharging platform, the especially a kind of and chain material elevator discharging platform protective door interlock protection device of control circuit material elevator.
Technical background
At present, material elevator is the camp site common equipment, and the discharging platform protective door is not closed or the phenomenon that is not closed completely happens occasionally in the use, forms and faces limit hidden danger, threatens operating personnel's safety, and consequent safety misadventure happens occasionally.
Basic ideas of the present utility model are:
Chain discharging platform protective door and winch, protective door is made the tool-type protective door, and installation protective door inter locking gear, when protective door is in open mode, winch can not start, have only when protective door close put in place after, winch could start, so just guaranteed that the discharging platform protective door that is in each floor must be in closed condition technically, winch ability energized, just can enter mode of operation, thereby eliminate formed potential safety hazard because the discharging platform protective door is not closed completely.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of material elevator discharging platform protective door interlock protection device that winch can not start when the discharging platform protective door is not closed or is not closed completely.
The technical scheme in the invention for solving the technical problem is:
A kind of material elevator discharging platform protective door interlock protection device; form by left side fan protective door, right wing protective door and bolt; left side fan protective door is installed on the left column by upper left hinge and lower-left hinge; the right wing protective door is installed on the right column by upper right hinge and bottom right hinge; left part at bolt is equipped with Protection switch, and the feeler lever of Protection switch puts in the door bolt tube of bolt.
The technical scheme in the invention for solving the technical problem can also be:
The utility model is provided with recoil spring in the door bolt tube of bolt.
Protection switch described in the utility model is the on-off switch that a pair of open contact and a pair of normally closed contact are arranged, the a pair of open contact of Protection switch is serially connected on the start-up control circuit of material elevator, a pair of normally closed contact of Protection switch behind indicator lamp of serial connection with the start-up control circuit of material elevator and connect.
Material elevator discharging platform described in the utility model has a plurality of in vertical direction, a pair of open contact at Protection switch set on each material elevator discharging platform is serially connected on the start-up control circuit of material elevator, on each material elevator discharging platform a pair of normally closed contact of set Protection switch behind indicator lamp of serial connection with the start-up control circuit of material elevator and connect.
The beneficial effects of the utility model are:
Because indicator lamp is corresponding one by one with protective door, protective door is not closed or is not closed completely, winch can not normally start, the winch driver is by the protective door status indicator lamp in the winch protection canopy, promptly know the layer position of not closing protective door, so that the personnel that remind in this layer operation in time close protective door, avoided because of not closing the safety misadventure that protective door or protective door are not closed completely and take place.
Mode of operation explanation: when each layer protective door all is in closed condition, elevator system is in normal working, the limit switch that is installed on each layer protective door is in operating state, the open contact XK1-n closure of limit switch, the control loop power connection, the limit switch normally closed contact is opened, and the door status indicator lamp extinguishes; When certain layer of protective door was in opening, the limit switch that then is loaded on this resetted, and the open contact XK1-n of limit switch opens, the control loop supply disconnecton, main control loop can not be worked, limit switch normally closed contact closure, door status indicator lamp energising light; Hoistman can judge and not cut out layer position, protective door place according to the state of door status indicator lamp, has made things convenient for operation, has guaranteed in time closing of each floor discharging platform protective door.
