Abstract
The utility model discloses a tensioning device of an elevator speed governor. When an elevator is overhauled, beating sticks are inserted into inserting holes of tensioning rope sheaves, the movement of the tensioning rope sheaves is stopped, moreover, the beating sticks touch a safety switch, so that a safety circuit of the elevator is disconnected, and the elevator stops working. Speed governor steel wire ropes and the tensioning rope sheaves keep motionless. The static friction force between the speed governor steel wire ropes and the tensioning rope sheaves can be greater than the driving force through which the speed governor steel wire ropes drive an elevator safety tong control mechanism to move. If an accidental slippage happens to the elevator, the steel wire ropes are guaranteed to be out of slippage inside rope grooves of the rope sheaves of the steel wire ropes due to the friction force between the speed governor steel wire ropes and the tensioning rope sheaves, when the elevator moves down accidentally, the speed governor steel wire ropes can be used for driving the elevator safety tong control mechanism to move, then the elevator is stopped, the elevator is prevented from further moving down, the safety of operators in the process of pit operations is guaranteed, and the safety performance of the elevator is improved.

Accompanying drawing 2 is schematic side view of the present utility model (not shown cage guide, speed limiter wire rope), wherein beats the jack that rod breaks away from tension sheave, and does not touch safety switch;
Accompanying drawing 3 also is schematic side view of the present utility model (not shown cage guide, speed limiter wire rope), wherein beats the jack that rod inserts tension sheave, and touches safety switch.
The specific embodiment
Further set forth structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-3, a kind of elevator over-speed governor tensioning apparatus, comprise connecting panel 1, rope sheave plate 3, tension sheave 4, speed limiter wire rope 8, beat rod 6, safety switch 7, connecting panel 1 is fixed on the cage guide 12, one end of rope sheave plate 3 rotates by turning cylinder 2 and is arranged on the connecting panel 1, the other end of rope sheave plate 3 fixedly has clump weight 10, tension sheave 4 is equipped with at the position of rope sheave plate 3 between two ends, this tension sheave 4 can be in 3 rotations of rope sheave plate, and the direction of axis line of the wheel shaft 5 of tension sheave 4 parallels with the direction of axis line of the turning cylinder 2 of rope sheave plate 3.Speed limiter wire rope 8 is walked around tension sheave 4 downwards, when elevator normally moves, speed limiter wire rope 8 drives tension sheave 4 normal rotation along with the operation of elevator, and when the elevator abnormal running, speed limiter wire rope 8 can drive the action of elevator safety gear steering unit and then stop elevator.Tension sheave 4 has a plurality of jacks 11 at the radial surface of wheel body, playing rod 6 can be arranged on the connecting panel 1 movably, by movement, play rod 6 and can insert or break away from jack 11, beat the moving direction of rod 6 along the direction of axis line extension of the wheel shaft 5 of tension sheave 4.Safety switch 7 is contained on the connecting panel 1, and safety switch 7 is selected travel switch for use, and this safety switch 7 is serially connected in the safety return circuit of elevator, can disconnect after safety switch 7 is touched, thereby disconnect elevator safety loop, makes elevator out of service.When elevator normally moves, corresponding to being in normal condition when elevator, shown in Fig. 1-2, beat the jack 11 that rod 6 breaks away from tension sheave 4, playing rod 6 so is not on the motion path of tension sheave 4, and play rod 6 and do not touch safety switch 7, safety switch keeps conducting like this, makes the safety return circuit of elevator also can keep conducting, thereby allow elevator normally to move, along with the operation of elevator, tension sheave 4 normal rotation make speed limiter wire rope 8 keep tensioning.Preparing and will overhaul elevator, the mobile rod 6 of beating is played rod 6 and is touched safety switch 7 earlier, continues then to stretch in the jack 11 of tension sheave 4.Corresponding to being in inspecting state when elevator, as shown in Figure 3, playing rod 6 is inserted in the jack 11 of tension sheave 4, playing rod 6 is on the rotation path of tension sheave 4, stoped the action of tension sheave 4 like this, and play rod 6 and touched safety switch 7, safety switch 7 disconnects, thereby make the safety return circuit of elevator also disconnect, elevator is out of service, keep static between speed limiter wire rope 8 and the tension sheave 4, and the static friction force between speed limiter wire rope 8 and the tension sheave 4 can drive the propulsive effort of elevator safety gear steering unit action greater than this speed limiter wire rope 8, the elevator that do not meet with an accident this moment can keep slack, thereby guarantees to carry out at the elevator melt pit personnel's of upkeep operation safety.If but unexpected slippage has appearred in elevator, because the friction force between speed limiter wire rope 8 and the tension sheave 4 has guaranteed that steel rope 8 is non-slip in the grooving of rope sheave 4, then when moving down, the elevator accident can drive the action of elevator safety gear steering unit by speed limiter wire rope 8, and then stop elevator, stoped further moving down of elevator, guarantee the safety of operating personnel when the melt pit operation, improve the safety performance of elevator.
