Description
Technical field
The present invention relates to a kind of elevator traction mechanism, relate in particular to a kind of elevator traction machine and use safety precaution mechanism.
Background technology
The elevator of elevator, especially vertical lift is to rely on the pulling force of many hauling ropes to do the vertical takeoff and landing (VTOL) operation aloft, in case hauling rope ruptures in operational process; Might cause casualties, consequence such as device damage, all can be furnished with velocity limiter on the general elevator, when the descending speed of car surpasses certain value; Velocity limiter can drive the safety tongs action; Car is clamped on the guide rail,, but still has unsettled defective of performance and problem though this kind mode can play the certain protection effect.
The Chinese patent Granted publication number is CN2897955Y; Granted publication day is that the utility model patent on May 9th, 2007 discloses a kind of jacking system hoist ropes rope break detection device; Comprise that switch bracket, detector switch, switch re-pack and the fag end device of hoist ropes; Switch bracket is fixed on the rope hitch plate of fag end device, and switch re-packs the rope head spring that is fixed on the fag end device away from an end of rope hitch plate, and detector switch is fixed on the switch bracket.Though this utility model can detect the disconnected rope situation of jacking system hoist ropes timely, its in use need be on every hoist ropes installation and measuring devices all, so not only wasting space also can disturb each other, to such an extent as to less stable.
Summary of the invention
Technical matters to be solved by this invention provides a kind of simple in structure, and the elevator traction machine of stable performance is used safety precaution mechanism.
For solving the problems of the technologies described above; The technical scheme that the present invention adopted is: a kind of elevator traction machine is used safety precaution mechanism; Comprise two levels, a relative left side that is arranged in car top chute bar, right only stop bar and only stop on a said left side bar and the said right side electromagnet between the bar of only stopping of only stopping; Only stop and be provided with the elasticity original paper between bar and the said car top in only stop bar and the said right side, a said left side; Also be provided with pin in the said chute, said pin be positioned at said chute the pin groove and can elastomeric telescopic moving, said electromagnet is connected with power supply through the lead that is wrapped on the whole traction steel wire.
Only stop bar and the said right side, a said left side only stops that an end of nearly car guide rail is equipped with the piece of only stopping on the bar.
The rubber of stating the piece of only stopping and the be rectangle piece of only stopping.
Said elastic element is a coil spring.
Compared with prior art, beneficial effect of the present invention is:
Because elevator traction machine of the present invention is provided with a left side only stop bar, the right side only stop bar and electromagnet with safety precaution mechanism, during use, electromagnet energising generation magnetic; A left side only stop bar and the sedan-chair case guide rail of bar and the right side of only stopping is separated, and when traction steel wire ruptured, the lead that twines above that will inevitably rupture; This moment, electromagnet just can lose magnetism because of outage; Meanwhile the left side bar of only stopping can finally be squeezed on the car guide rail respectively to sedan-chair case guide rail movement under the effect of elasticity original paper with the right bar of only stopping, and pin also can stretch out pin groove prevention left side bar and the right side bar of only stopping of only stopping and slides back; Under function of friction, make car stop to fall; This process is simply effective, so the present invention is simple in structure, stable performance.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment:
Fig. 1 is a structural representation of the present invention.
Among the figure: car 2, the left side bar 4 of only stopping, the right side bar 6 of only stopping, electromagnet 8, elasticity original paper 10, pin 12, pin groove 14, the piece 16 of only stopping, sedan-chair case guide rail 5.
The specific embodiment
As shown in Figure 1; A kind of elevator traction machine of the present invention is used safety precaution mechanism; Include two levels, a relative left side that is arranged in the car 2 top chutes only stop bar 4, right bar 6 and only stop on a left side bar 4 and the right electromagnet of only stopping between the bar 68 only stopped; Be provided with elasticity original paper 10 between the top of wherein left only stop bar 4 and right only stop bar 6 and car 2; Also be provided with pin 12 in the chute, this pin 12 be positioned at chute pin groove 14 and can elastomeric telescopic moving, electromagnet 8 is connected with power supply through the lead (not shown) that is wrapped on the whole traction steel wire.
In actual the use, for further enhancing only stop effect only stop bar 4 and the right bar 6 of only stopping on a left side on an end of nearly car guide rail 8 piece 16 of only stopping is installed, the piece 16 of preferably stopping is the rubber of the rectangle piece of only stopping, and elastic element 10 is a coil spring.
Braking principle of the present invention is: electromagnet 8 energising backs produce magnetic; Left side bar 4 and the right side bar 6 of only stopping of only stopping is separated with sedan-chair case guide rail 5; When traction steel wire ruptured, the lead that twines above that will inevitably rupture, and this moment, electromagnet 8 just can lose magnetism because of outage; The meanwhile left bar 4 of only stopping can be respectively to 5 motions of sedan-chair case guide rail under the effect of elasticity original paper 10 with the right bar 6 of only stopping; Finally be squeezed on the car guide rail 5, and pin 12 also can stretch out pin groove 14 prevention left sides bar 4 and the right side bar 6 of only stopping of only stopping and slides back, and under function of friction, makes car 2 stop to fall.
In sum, traction machine of the present invention is simple with the safety precaution mechanism structure, stable performance.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
