The technical proposal of the utility model is to provide an easy using and labor saved door opening and closing device used in industry door when power cut. The utility model comprises a motor shaft, two connecting wheels, a chain wheel, a connecting shaft, a pressure spring, a case, a chain and a limiting switch. One connecting wheel with tooth on the end surface is fixed on the motor shaft. The other connecting wheel is sleeved on the end of the connecting shaft. One end surface of the connecting shell is also provided with tooth and the end surface with tooth matches with the end surface of the other connecting wheel with tooth. The chain wheel is fixed on the connecting shaft. The rotation of the chain wheel drives the rotation of the connecting shaft. The connecting shaft is fixed on the case. The connecting shaft is provided with a mechanism which makes the connecting wheel of the shaft do reciprocating motion in the axle direction. The limiting switch is fixed on the case.

The utility model has the advantages such as easy operation.
Description
Technical field
The utility model relates to the door opening/closing apparatus that uses on a kind of industrial door machine, especially realizes the device of switch door when having a power failure.
Background technology
The mechanical mechanism that is used for a kind of switch door on industrial door opener, the door-rolling machines such as factory building, garage, warehouse now mostly is to use under the situation that electricity is arranged, yet wait in particular cases in power failure, because the door lifter that has does not have hand gear, thereby when outage, have to stop using; The door lifter that has has hand gear, but since from electronic to manual conversion equipment complicated operation and will using could realize conversion very energetically, thereby this problem has become one to be badly in need of the technical problem that solves.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, the door opening/closing apparatus of the door lifter when easy to use and labour-saving industrial door machine has a power failure.
The door opening/closing apparatus of door lifter of the present utility model, it comprises motor shaft, two fifth wheels, sprocket wheel, connecting axle, stage clip, casing, chain, limit switch; Fix a toothed fifth wheel of end face on the described motor shaft; Described another connects the end that bye is enclosed within connecting axle, and an end face of described this fifth wheel also is with tooth, and the toothed end face of this fifth wheel matches with the toothed end face of another fifth wheel; Sprocket wheel is fixed on the connecting axle, the rotating band of sprocket wheel be dynamically connected the axle rotation; Connecting axle is fixed on the casing, has one to make fifth wheel on this in the mechanism of axially reciprocating on the connecting axle; Described limit switch is fixed on the casing, and limit switch contacts with fifth wheel on the connecting axle, and connecting axle is when motor shaft moves, and limit switch does not contact with fifth wheel.
Described reciprocating mechanism can be that the fifth wheel on the described connecting axle has an end face to contact with sprocket wheel, described contacted end face has deep-slotted chip breaker, with ball, described connecting axle has spring in deep-slotted chip breaker, and spring is in contact with one another fifth wheel and the sprocket wheel on the connecting axle; There is projection on fifth wheel surface on the described connecting axle, has one to hinder the mechanism that fifth wheel rotates on the connecting axle on the casing.
The mechanism that fifth wheel rotates on the described obstruction connecting axle can be the hollow cylinder of fixedlying connected with casing, described connecting axle passes this hollow cylinder, this hollow cylinder and casing are integral, on the inner surface of hollow cylinder or the end face projection is arranged, when the fifth wheel on the connecting axle contacts with the sprocket wheel end face, rotating sprocket, the projection of hollow cylinder and the fifth wheel projection on the connecting axle are collided, stoped the rotation of fifth wheel, make that fifth wheel moves to another fifth wheel on the connecting axle, this moment described projection separately.
The cooperation of described two fifth wheels is meant when two sprocket wheels are mutual and meshes together near opposing end faces that connecting axle rotates the rotation that just drives motor shaft.
The door opening/closing apparatus of described door lifter is have a power failure to wait in particular cases, realizes conversion electrically and manually fast, is a kind of emergent means, and the industrial door machine is when having electricity, and the driven by motor worm and gear rotates, thereby realizes the switch of slide-lifting door.Yet wait in particular cases in power failure, by pulling chain, make sprocket rotation, helicoid on the sprocket wheel end face makes the fifth wheel against the force of the spring on the connecting axle travel forward by ball, make the end face tooth of two fifth wheels mesh together, continue the pulling chain, sprocket wheel constantly rotates, drive rotor from face by fifth wheel and rotate, realize the switch door.In this process, because fifth wheel travels forward on the connecting axle, make that the button on the limit switch flicks, the machine outage plays the safeguard protection effect.In case openhanded open chain bar, fifth wheel resets under the effect of spring on the connecting axle, and the limit switch button continues to be pushed down, and can carry out automatic door this moment again.
Have characteristics such as safe in utilization, easy to operate according to above-described door opening/closing apparatus.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The door opening/closing apparatus of door lifter of the present utility model, it comprises motor shaft 11, two fifth wheels 10 and 12, sprocket wheel 4, connecting axle 1, spring 6, casing 5, chain 7, limit switch 8, chain cover 3, copper sheathing 2 etc.; Fix a toothed fifth wheel 10 of end face on the described motor shaft; Described another fifth wheel 12 skies are enclosed within the end of connecting axle 1, and an end face of described this fifth wheel 12 also is with tooth, and these fifth wheel 12 toothed end faces match with another fifth wheel 10 toothed end faces; Sprocket wheel 4 is fixed on the connecting axle 1, axle 1 the rotation that is dynamically connected of the rotating band of sprocket wheel 4; Connecting axle 1 is fixed on the casing 5, has one to make fifth wheel 12 on this in the mechanism of axially reciprocating on the connecting axle 1; Described limit switch 8 is fixed on the casing 5 by screw 9, limit switch 8 contacts with fifth wheel 12 on the connecting axle, and when fifth wheel 12 when motor shaft 11 moves, limit switch 8 does not contact with fifth wheel 12, described reciprocating mechanism is that the fifth wheel 12 on the described connecting axle has an end face to contact with sprocket wheel 4, described contacted end face has deep-slotted chip breaker, and ball 13 is arranged in deep-slotted chip breaker, and spring 6 makes the fifth wheel 12 on the connecting axle be in contact with one another with sprocket wheel 4; There is projection on fifth wheel 12 surfaces on the described connecting axle, also comprise the hollow cylinder of fixedlying connected with casing, described connecting axle passes this hollow cylinder, this hollow cylinder and casing are integral, on the inner surface of hollow cylinder or the end face projection is arranged, when the fifth wheel on the connecting axle contacts with the sprocket wheel end face, rotating sprocket, the projection of hollow cylinder and the fifth wheel projection on the connecting axle are collided, stoped the rotation of fifth wheel, make that fifth wheel moves to another fifth wheel on the connecting axle, this moment described projection separately.
