Abstract
The invention relates to a novel elevator overspeed protection device, comprising a car guide rail, a safe friction block and a triggering component. The triggering component comprises a rotating rod, a first connecting rod, a second connecting rod and a drive rod. Two ends of the rotating rod are movably connected with the car guide rail, and the drive rod is fixedly connected with one end of the rotating rod. The upper end of the drive rod is connected with the rope of a speed governor. The novel elevator overspeed protection device has the advantage that, the device adopts the safe friction block to replace safety tongs, and the car stops moving due to the effect of the friction force. Overspeed protection is performed. According to the novel elevator overspeed protection device, the structure is further simplified, and the installation is more convenient.
Description
Technical field
The present invention relates to elevator functions assembly, be specifically related to a kind of device for carrying out overspeed protection to elevator.
Background technology
Elevator is a kind of for mechanical device that is manned or loading.Elevator must reach certain safety rate just can place in operation.Its principle of work is, ining succession car and counterweight respectively in hoist ropes two ends, is wrapped in traction sheave and track adjusting wheel, hoisting motor is by driving traction sheave to rotate after retarder speed change, by hoist ropes and the fricative tractive force of traction sheave, realize the dipping and heaving of car and counterweight, reach transport object.In transportation, often due to reasons such as motor drive errors, elevator overspeed occurs, the elevator therefore meeting safety rate must possess elevator overspeed protecting device.Existing elevator governor forms primarily of velocity limiter, steel rope, safety tongs and tension wheel, and safety tongs is wherein by the elevator device of stop on guide rail by force with mechanical action.Existing safety tongs complex structure, therefore brings certain difficulty to installation.
Summary of the invention
The deficiency that the present invention overcomes background technology provides a kind of novel elevator overspeed protection device, and this device utilizes new mechanism to replace safety tongs, simplifies the structure of elevator overspeed protecting device, makes easier for installation.
The invention provides following technical proposals: a kind of novel elevator overspeed protection device, comprise car guide rail, safe friction shoe, trigger elements.Described trigger elements comprises revolving bar, head rod, the second pipe link, drive spindle.The two ends of described revolving bar are flexibly connected with described car guide rail, and described drive spindle is fixedly connected with one end of described revolving bar.The upper end of described drive spindle is connected with governor rope, and the lower end of described drive spindle is connected with hoistway by fixing steel rope, and one end of described head rod is fixedly connected with described revolving bar.The other end of described head rod is flexibly connected with one end of described second pipe link.The other end of described second pipe link is flexibly connected with described car guide rail.
Further; described novel elevator overspeed protection device also comprises nutted rod; the other end of described head rod is flexibly connected with one end of described nutted rod with the active connection place, one end of described second pipe link, and the other end of described nutted rod is connected with the body of described safe friction shoe.
Further, the locus of described drive spindle tilts.
Beneficial effect of the present invention is: this device utilizes described safe friction shoe to replace safety tongs, makes described car stop motion by the effect of friction force.Carry out overspeed protection.This technical scheme further simplify the structure of elevator overspeed protecting device, makes easier for installation.
Accompanying drawing explanation
Fig. 1 is the front view of elevator overspeed protecting device of the present invention.
Fig. 2 is the back view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described.
In Fig. 1, Fig. 2: car guide rail 1, safe friction shoe 2, revolving bar 3, head rod 4, second pipe link 5, drive spindle 6, nutted rod 7.
A kind of novel elevator overspeed protection device, comprises car guide rail 1, safe friction shoe 2, trigger elements.Described trigger elements comprises revolving bar 3, head rod 4, second pipe link 5, drive spindle 6.The two ends of revolving bar 3 are flexibly connected with car guide rail 1, and drive spindle 6 is fixedly connected with one end of revolving bar 3.The upper end of drive spindle 6 is connected with governor rope.The lower end of drive spindle 6 is connected with hoistway by fixing steel rope.When car speed is too fast, velocity limiter wheel produces self-locking, stops operating.Car continues motion and pulls drive spindle 6 to produce swing, produces spinning motion by the swing driven rotary bar 3 of drive spindle 6.
One end of head rod 4 is fixedly connected with revolving bar 3.The other end of head rod 4 is flexibly connected with one end of the second pipe link 5.The other end of the second pipe link 5 is flexibly connected with car guide rail 1.The flexion and extension of the connecting rod mechanism that the spinning motion that the object of such connection is produced by the swing driven rotary bar 3 of above-mentioned drive spindle 6 drives head rod 4 and the second pipe link 5 to form.
Described novel elevator overspeed protection device also comprises nutted rod 7, and the other end of head rod 4 is flexibly connected with one end of nutted rod 7 with the active connection place, one end of the second pipe link 5, and the other end of nutted rod 7 is connected with the body of safe friction shoe 2.The flexion and extension of the connecting rod mechanism consisted of above-mentioned head rod 4 and the second pipe link 5 is pullled safe friction shoe 2 and is extruded to car guide rail 1, and it is larger that speed extrudes dynamics sooner, until car stop motion.Which is for by providing friction force to make car stop motion.
The locus of drive spindle 6 tilts.The implication of described inclination is, drive spindle 6 can drive revolving bar 3 to drive under the driving of steel rope.
