Abstract
The utility model relates to a simple elevator landing door unlocking device driven by linear actuator motor. The device comprises a linear actuator motor 1, a linear actuator motor pedestal 2, a linear actuator motor extension arm 3 and a landing door unlocking collision bow 4, wherein the linear actuator motor 1 is fixed on the linear actuator motor pedestal 2 by bolts, the linear actuator motor extension arm 3 is connected with the push rod shaft of the linear actuator motor 1 by bolts, the landing door unlocking collision bow 4 is fixed on the linear actuator motor extension arm 3 through electric-arc welding, and the push rod shaft of the linear actuator motor 1 performs linear reciprocating motion to drive the landing door unlocking collision bow 4 to control opening and closing of a door lock of the simple elevator landing door. The simple elevator landing door unlocking device driven by linear actuator motor is simple in structure and convenient to mount, generates low noise in use, has long service life and moderate cost, and can completely meet the safety technological requirement and daily use requirement of the simple elevator.
Description
Technical field
The utility model, for realizing the open and close of the normal use procedure of simplified elevator middle level door lock, guarantees that operating personal can the opening and closing goods-carriage-door of safety and a kind of device of layer door.
Background technology
At present, it in industry, is the requirement that meets 7.1.6 bar in GB28755-2012 simplified elevator safety procedure, generally adopt the storey door unlocking device that push-pull electromagnet drives or minitype speed reducing motor drives, control the open and close of simplified elevator layer door lock.These two kinds of apparatus structure complexity, to manufacture difficulty, service life low, particularly the thrust of electromagnet and the moment of torsion of minitype speed reducing motor are smaller, can be because promote or pull the power of layer door lock cannot open a layer door lock not under specific condition, if adopt the electromagnet of high thrust and the minitype speed reducing motor of high pulling torque, selling at exorbitant prices, volume be large, trouble is installed.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of motor-driven simplified elevator storey door unlocking device of employing electric pushrod that can guarantee simplified elevator safety, reliability service is provided.
For achieving the above object, the technical scheme that the utility model adopts is: the motor-driven simplified elevator storey door unlocking device of electric pushrod, this device comprises that electric pushrod motor 1, electric pushrod motor base 2, electric pushrod motor extension arm 3, the release of layer door hit bow 4 and form, and described electric pushrod motor 1 is fixed by bolts on electric pushrod motor base 2; Described electric pushrod motor extension arm 3 is connected with electric pushrod motor 1 push rod shaft by bolt; The release of described layer door is hit bow 4 use arc weldings and is fixed on electric pushrod motor extension arm 3, hits bow 4 move in the horizontal direction by a straight reciprocating motion drive layer door release for electric pushrod motor 1 push rod shaft.
The cross-sectional plane of above-mentioned electric pushrod motor extension arm 3 is L-type, and two sides has through hole 5 and through hole 6.
The diameter of above-mentioned through hole 5 is greater than the diameter of the through hole 7 in described electric pushrod motor 1 push rod shaft, and the diameter of through hole 6 is greater than the diameter of described electric pushrod motor 1 push rod shaft.
Compared with prior art, the utility model is simple in structure, easy for installation, and use noise is low, the life-span is long, reliability is high, cost is moderate, can meet safety specifications and the routine use requirement of simplified elevator completely.
Accompanying drawing explanation
Fig. 1 is the utility model perspective view;
Fig. 2 is the utility model exploded view;
In figure: 1 electric pushrod motor; 2 electric pushrod motor bases; 3 electric pushrod motor extension arms; Bow is hit in 4 layers of door release; 5 through holes; 6 through holes; 7 through holes
The specific embodiment
As depicted in figs. 1 and 2, the motor-driven simplified elevator storey door unlocking device of electric pushrod, comprises that electric pushrod motor 1, electric pushrod motor base 2, electric pushrod motor extension arm 3 and the release of layer door hit bow 4, and by the release of layer door, hits bow 4 and form.
During use, simplified elevator moves to flat bed layer door unlocked position, after coming to a complete stop, by simplified elevator electric control system, make electric pushrod motor 1 energising rear push-rod shaft extension go out or retract, driven the release of layer door to hit bow 4 and moved horizontally, the motion of then hitting bow 4 by the release of layer door realizes the open and close of simplified elevator layer door lock.
More than describe preferred embodiment of the present utility model in detail, should be appreciated that the ordinary skill of this area just can be made many modifications and variations according to design of the present utility model without creative work.Therefore, all technical personnels in the art according to the utility model design on prior art basis by logic analysis, reasoning or according to the available technical scheme of limited experiment, all should be among the determined protection domain of these claims.
