The utility model adopts the technical scheme that the structure is simple, the braking is timely and reliable, the railcar can be immediately braked without circuit detection when the steel wire rope breaks, safety accidents are avoided, and the safety mechanism is convenient to install and has low cost.
Description
Technical field
The utility model relates to a kind of elevator, specifically, is a kind of safety gear that is used for passageway lift.
Background technology
The elevator that uses in the present social reality mainly contains two classes, and a class is a box-type elevator vertically, a class be along the slope go up continuously or under escalator.This two classes elevator is because of taking building area and the space is bigger, the cost height, and not economical and practical to the residence building that floor is not high, the passageway lift that therefore solves this type of problem arises at the historic moment.Retrieve the patent of invention of the patent No. for the passageway lift of " 200710071436.X ", its structure is: with each section corridor is one unit, be separately installed with the elevator of independent operating, described elevator is installed on the corridor side, described elevator comprises the ladder that is provided with along the corridor gradient direction, and described ladder is provided with and gets on the right track, lower railway, rail vehicle, draw gear, closing appliance and control system.Every corridor have one one can independent operating elevator, increased transportation load greatly, and every elevator adopts closing appliance, the time spent can not be full closeding state, safety again elegant in appearance has also reduced fault rate simultaneously.But, adopt the insurance parts and the safe tooth interlock brake structure of electric armature form in the above-mentioned patent, when running into the emergency situation that haulage cable breaks, need to detect wire cable rupture by detector switch earlier, transmitting signals to apparatus for controlling elevator again controls the outage of electric armature by it and puts down the interlock iron plate itself and safe tooth interlock are braked, like this in case the detector switch fault appears, electric armature does not cut off the power supply, just very easily cause safety gear to lose efficacy and threaten personal security, simultaneously, this safety gear has that structure is too complicated, braking response waits problem slowly.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of safety gear that is used for passageway lift, simple in structure effectively, immediately can the braking orbit car when steel rope is disconnected, avoid safety misadventure.
The technical solution of the utility model is as follows:
A kind of safety gear that is used for passageway lift, comprise rail vehicle, ladder, motor and apparatus for controlling elevator, motor is by the rope traction rail vehicle, ladder is provided with safe tooth, described rail vehicle below be hinged with can with the interlock iron plate of safety tooth interlock braking, described steel rope is connected with pull bar on being slidingly arranged in rail vehicle, and pull bar is connected with the springing of giving its return trend, and pull bar is provided with and can makes safe tooth and interlock iron plate break away from the pressure head of interlock after the pull bar displacement.
As preferably, described springing is the stage clip that is set on the pull bar, and stage clip one end and pull bar offset, and the stage clip other end and rail vehicle offset, described pressure head be fixedly installed on the pull bar and can with the last end in contact of the interlock iron plate of its below, the lower end of interlock iron plate can with the interlock of safety tooth.Simple and reliable for structure like this.
As preferably, described rail vehicle is provided with the safety switch that can be triggered when the pull bar return, and safety switch is connected with apparatus for controlling elevator.Apparatus for controlling elevator can in time be known the braking situation of rail vehicle by detector switch, thereby the controlled motion parts are made corresponding safe action.
The technical solution of the utility model, simple in structure, braking is in time reliable, when steel rope is disconnected, do not need just braking orbit car immediately of electric circuit inspection, avoid safety misadventure, also have problems such as easy for installation, that cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the topology view from top to bottom of interlock iron plate in the utility model.
Among the figure 1, rail vehicle; 2, ladder; 3, safe tooth; 4, pull bar; 5, stage clip; 6, pressure head; 7, safety switch; 8, steel rope; 9, motor; 11, interlock iron plate.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Embodiment 1:
A kind of safety gear that is used for passageway lift as shown in Figure 1, comprise rail vehicle 1, ladder 2, motor 9 and apparatus for controlling elevator, motor 9 is by steel rope 8 traction track cars 1, ladder 2 is provided with safe tooth 3, described rail vehicle 1 below be hinged with can with the interlock iron plate 11 of safety tooth 3 interlocks brakings, described steel rope 8 is connected with pull bar 4 on being slidingly arranged in rail vehicle 1, pull bar 4 is connected with the springing of giving its return trend, and pull bar 4 is provided with and can makes safe tooth 3 and interlock iron plate 11 break away from the pressure head 6 of interlock after pull bar 4 displacements.
In the present embodiment, described springing is the stage clip 5 that is set on the pull bar 4, stage clip 5 one ends and pull bar 4 offset, stage clip 5 other ends and rail vehicle 1 offset, described pressure head 6 be fixedly installed on the pull bar 4 and can with the last end in contact of the interlock iron plate 11 of its below, the lower end of interlock iron plate 11 can with 3 interlocks of safety tooth.Described rail vehicle 1 is provided with the safety switch 7 that can be triggered when pull bar 4 returns, safety switch 7 is connected with apparatus for controlling elevator.
As shown in Figure 2, the upper end of interlock iron plate 11 is the projection 113 that can conflict with top pressure head 6, the upper end of interlock iron plate 11 be can with safety tooth 3 ingear ratchets 111, the stage casing is provided with and rail vehicle 1 pivotally attached jointed shaft 112, the weight of its lower end is much larger than the upper end, thereby makes the lower end ratchet 111 of interlock iron plate 11 can fall under state of nature and brake with 3 interlocks of safety tooth; And when producing displacement obliquely under the tractive force effect of pull bar 4 at steel rope 8, pressure head 6 on the pull bar 4 props up the upper end projection 113 of interlock iron plate 11, stop the lower end ratchet 111 of interlock iron plate 11 to fall, safety gear breaks away from braking, rail vehicle can be under the traction of motor up-and-down movement; And when steel rope 8 breaks or be lax, pull bar 4 is downward return under the effect of stage clip 5 restoring forces, pressure head 6 on the pull bar 4 no longer props up the upper end projection 113 of interlock iron plate 11, the lower end ratchet 111 of interlock iron plate 11 is subjected to the deadweight whereabouts and brakes with 3 interlocks of safety tooth, simultaneously, safety switch 7, the concurrent warning of being out of order of apparatus for controlling elevator disable motor power supply are triggered in the lower end of pull bar 4.
The utility model is not limited to the foregoing description, and for example elastic potential energy device wherein can also adopt the structure of forms such as extension spring, cylinder, for example can give the trend that interlock iron plate lower end ratchet falls by allied equipments such as torsion springs.
