Abstract
The invention discloses a tightening device for an elevator over-speed governor. A roller on the bracket can prop against on an over-speed governor steel wire rope in a rolling manner through a bracket by virtue of elastic restoring force of an elastic piece, so that the steel wire rope is tightened without the need of a balancing weight. The tightening device provided by the invention has a light structure and low cost. After the steel wire rope extremely extends, the elastic restoring force of the elastic piece drives the bracket to move, so that a switch panel on the bracket touches a limiting switch on an installation plate for switching off a safety loop of an elevator, and stopping the operation of the elevator, so as to ensure the using safety of the elevator.

For achieving the above object, the technical solution used in the present invention is: a kind of elevator over-speed governor tensioning apparatus, comprise the adapter plate in the hoistway that is fixed on elevator, the wheel axle horizontal is contained in the tension wheel on the described adapter plate, walk around the speed limiter wire rope of described tension wheel downwards, be arranged on rotationally the support on the described adapter plate, be contained on the described support and be positioned at described tension wheel top and the roller on described speed limiter wire rope of can rollably conflicting, being arranged on can provide this rack elasticity restoring force between described support and the described adapter plate so that the elastic component of the roller conflicting on this support on described speed limiter wire rope, be arranged on the limit switch that can after being touched, disconnect on the described adapter plate, be arranged on the switch that can touch described limit switch on the described support when described speed limiter wire rope excessively extends and re-pack, described limit switch is serially connected in the safety return circuit of elevator.
During implementation, described roller can rollably be conflicted in the outside of described speed limiter wire rope.
During implementation, the wheel direction of axis line of the rotational axis line direction of described support, described roller all parallels with the wheel direction of axis line of described tension wheel.
During implementation, the two opposite outer at described tension wheel on the described adapter plate is provided be used to stopping that described speed limiter wire rope breaks away from the gear rope bar of described tension wheel.
During implementation, described adapter plate is fixed on the cage guide.
During implementation, be provided with the rope sheave guard shield that is located at described tension wheel top on the described adapter plate.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages: in this elevator over-speed governor tensioning apparatus, support rely on elastic component elastic-restoring force so that the roller on the support rollably conflict on speed limiter wire rope, realize the tensioning of steel rope, need not like this to use clump weight to carry out tensioning, the tensioning device structure of this patent is light and handy, and cost is low.Excessively extension after occuring in steel rope, and the elastic-restoring force driving arm of elastic component moves, the limit switch so that the switch on the support re-packs on the shake-up adapter plate, and the safety return circuit of disconnection elevator stops the elevator operation, guarantees the safety of elevator use.

Description of drawings
Accompanying drawing 1 is schematic diagram one of the present invention, and wherein speed limiter wire rope relies on the normal tensioning of conflict of roller, and switch re-packs and is separated with limit switch;
Accompanying drawing 2 is schematic diagram two of the present invention, and wherein steel rope excessively extends, and causes the switch shake-up limit switch that re-packs.
?
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1-2, a kind of elevator over-speed governor tensioning apparatus, comprise that adapter plate 1, tension wheel 3, speed limiter wire rope 6, support 11, roller 14, elastic component 12, limit switch 8, switch re-pack 10, adapter plate 1 is fixed in the hoistway of elevator, shown in Fig. 1-2, adapter plate 1 is fixed on the cage guide 5.Tension wheel 3 is contained on the adapter plate 1 by wheel shaft 2, and wheel shaft 2 is horizontally disposed with.Speed limiter wire rope 6 is walked around tension wheel 3 downwards.Be provided with rotationally support 11 on the adapter plate 1, roller 14 is contained on the support 11 by wheel shaft 13, and the direction of axis line of the direction of axis line of the turning cylinder 9 of support 11, the wheel shaft 13 of roller 14 all parallels with the direction of axis line of the wheel shaft 2 of tension wheel 3.Roller 14 is positioned at the top of tension wheel 3, and roller 14 can rollably be conflicted on speed limiter wire rope 6, realizes the tensioning of steel rope.Between support 11 and adapter plate 1, be provided with the elastic component 12 that these support 11 elastic-restoring forces can be provided, this elastic component 12 adopts Compress Spring, Compress Spring offer support 11 the elastic recovery pulling force so that the roller 14 on the support 11 stably conflict on speed limiter wire rope 6, such as Fig. 1, roller 14 can rollably be conflicted in the outside of speed limiter wire rope 6.Limit switch 8 is arranged on the adapter plate 1, and the switch that be used for to touch limit switch 8 re-packs and 10 is arranged on support 11.When elevator normally moves, rely on the elastic-restoring force of elastic component 12, roller 14 on the support 11 is rollably conflicted on speed limiter wire rope 6, so that steel rope 6 is in tensioning state, as shown in Figure 1, limit switch 8 re-packed with switch and 10 was separated this moment, and limit switch 8 is serially connected in the safety return circuit of elevator, remain closed, allow the elevator normal operation this moment.Speed limiter wire rope 6 occur to extend so that steel rope 6 become lax after, because the elastic-restoring force effect of elastic component 12, the speed limiter wire rope 6 so that roller 14 on the support 11 is conflicted further, realize the tensioning of steel rope 6, in the expanded range that steel rope 6 allows, limit switch 8 and switch re-pack and 10 keep separating, and still allow elevator normally to move this moment.After steel rope 6 excessively extends, after being the scope of scope above permission of steel rope 6 extensions, the elastic-restoring force of elastic component 12 drives support 11 to be continued to move further, the 10 shake-up limit switches 8 thereby switch re-packs, as shown in Figure 2, switch 8 disconnects, switch 8 is to be serially connected in the safety return circuit of elevator, and then the safety return circuit of elevator interrupts, and elevator can't carry out any action, namely stop the elevator operation, guaranteed the safety of elevator.
In Fig. 1, the two opposite outer at tension wheel 3 on the adapter plate 1 is provided with gear rope bar 4, and this gear rope bar 4 is used for stopping that speed limiter wire rope 6 breaks away from tension wheel 3.Also be provided with rope sheave guard shield 7 on the adapter plate 1, this rope sheave guard shield 7 is located at the top of tension wheel 3, is used for having prevented that foreign matter from dropping.
To sum up, in this elevator over-speed governor tensioning apparatus, support rely on elastic component elastic-restoring force so that the roller on the support rollably conflict on speed limiter wire rope, realize the tensioning of steel rope, need not like this to use clump weight to carry out tensioning, the tensioning device structure of this patent is light and handy, and cost is low.Excessively extension after occuring in steel rope, and the elastic-restoring force driving arm of elastic component moves, the limit switch so that the switch on the support re-packs on the shake-up adapter plate, and the safety return circuit of disconnection elevator stops the elevator operation, guarantees the safety of elevator use.
