Abstract
The utility model provides a traction transmission mechanism with a primary counterweight and a secondary counterweight. Both ends of one bearing wire rope group are respectively connected with an elevator car (suspension cage) and the primary counterweight, the middle part thereof goes through a traction sheave and one transition wheel, and both ends of the other safety wire rope group are respectively connected with the elevator car (suspension cage) and the secondary counterweight, the middle part thereof goes through a speed limit wheel and the other transition wheel, the speed limit wheel and a fan-shaped eccentric wheel are sleeved on the same shaft, when in over speed, the speed limit wheel forces the fan-shaped eccentric wheel to rotate to clamp the safety wire ropes, the primary counterweight and the secondary counterweight can freely slide up and down relatively by a certain distance S, and the safety wire ropes are always kept in the constant tension state under the gravity action of the secondary counterweight. The elevator car (suspension cage) and the counterweights all have the bidirectional over speed protection, the speed limit method is simple, the use and maintenance are convenient, safety accidents caused by over speed or rope breakage are eliminated radically, the optimum traction condition can be achieved, the service life is extended, and the energy saving effect is obvious.
Description
Technical field
The utility model relates to the dragging and driving mechanism of the female counterweight of a kind of belt, especially is suitable for various elevators, building hoist and other vertical transportation machinery with steel rope traction transmission.
Background technology
At present, known dragging and driving mechanism by traction sheave, one group of steel rope, transition wheel, a car (cage) and one to reassembling into.With the two ends of one group of steel rope respectively with a car (cage) and one to reconnecting; middle spaced winding is enclosed within on traction sheave and the transition wheel; when carrying means in the long-play process; when causing friction minimizing or other functional failure of electromechanical that car (cage) overspeed takes place because of wearing and tearing; because car (cage) has only downward overspeed protection; if the counterweight quality is during greater than car (cage) quality; car (cage) will be in the overspeed runaway condition that makes progress; in addition; as when one group of steel rope complete rupture takes place; at this moment, counterweight will drop with free-falling body, and these potential safety hazards all once took place with the accident form.
Summary of the invention
In order to overcome the deficiency that exists in the existing this dragging and driving mechanism.The utility model provides the dragging and driving mechanism of the female counterweight of a kind of belt.This dragging and driving mechanism adopt two groups of steel ropes with car (cage) and a pair of primary and secondary to reconnecting; wherein one group of insurance steel cable is middle by speed limited wheel and sub to reconnecting; under the normal circumstances; insurance steel cable only bears the gravity of sub-counterweight; all the time guarantee safe and reliable; speed limited wheel has the two-way speed limiting defencive function; car (cage) and counterweight all are subjected to overspeed protection up and down; improved the safety of car (cage) operation greatly, fundamentally having stopped can increase the counterweight quality because of hypervelocity or the disconnected safety misadventure of restricting and causing; improve the traction condition; reduce the actuating unit bearing load, increase the service life, cut down the consumption of energy.
The technical scheme that problem adopted that the utility model solves its technology is: one group of load-bearing wires rope two ends respectively with car (cage) and female to reconnecting, middle spaced winding is enclosed within on traction sheave and the transition wheel, and the two ends of another group insurance steel cable respectively with car (cage) and sub to reconnecting, middle spaced winding is enclosed within on speed limited wheel and another transition wheel, speed limited wheel and fan-shaped eccentric wheel are sleeved on the same axle, only when hypervelocity (speed limiting mechanism action), fan-shaped eccentric wheel is just followed the positive and negative rotation of speed limited wheel and is clamped insurance steel cable, son has certain sliding distance S to focusing in female counterweight, guarantee that primary and secondary is to Beijing South Maxpower Technology Co. Ltd's slide relative up and down freely, insurance steel cable remains constant tensioning state under the action of gravity of sub-counterweight.
The beneficial effects of the utility model are: car (cage) and weight average had bidirection overspeed protective; method for limiting speed is simple; working service is convenient; improved the safety of car (cage) operation greatly; fundamentally stopped because of hypervelocity or the disconnected safety misadventure of restricting and causing; can reach best traction condition, improve service life, energy-saving effect is remarkable.

The utility model is described in further detail below in conjunction with accompanying drawing and implementation column.
Fig. 1 is a fundamental diagram of the present utility model
Among Fig. 11, speed limited wheel, 2, fan-shaped eccentric wheel, 3, traction sheave, 4, car (cage), 5, insurance steel cable, 6, load-bearing wires rope 7, transition wheel, 8, female counterweight, 9, sub-counterweight.
The specific embodiment
In Fig. 1, one end of one group of load-bearing wires rope (6) is connected with car (cage) (4), middle spaced winding is enclosed within on traction sheave (3) and the transition wheel (7), the other end is connected with female counterweight (8), one end of one group of insurance steel cable (5) is connected with car (cage) (4), middle spaced winding is enclosed within on speed limited wheel (1) and another transition wheel (7), the other end is connected with sub-counterweight (9), speed limited wheel (1) is contained on the same axle with fan-shaped eccentric wheel (2), sub-counterweight (9) is sleeved in female counterweight (8), when the positive and negative rotation of traction sheave (3), under the effect of friction force, load-bearing wires rope (6) drives car (cage) (4) and female counterweight (8) moves up and down, at this moment, insurance steel cable (5) is under the action of gravity of sub-counterweight (9), drive speed limited wheel (1) and do synchronous positive and negative rotation, under the normal circumstances, fan-shaped eccentric wheel (2) vertically downward, do not rotate, when hypervelocity motion up or down takes place in car (cage) (4), speed limited wheel (1) is under the friction force effect of insurance steel cable (5), also make positive and negative overspeed rotation simultaneously, at this moment, the speed limiting mechanism action, force fan-shaped eccentric wheel (2) to make forward or reverse, insurance steel cable (5) sent into clamped and stop motion in the webge slot, sub-counterweight (9) has a slide relative apart from S in female counterweight (8), guarantee in the use, because of the overlapped phenomenon of primary and secondary counterweight does not take place in load-bearing wires rope (6) elongation, if the phenomenon of one group of load-bearing wires rope (6) complete rupture takes place, at this moment, female counterweight (8) is pressed on the sub-counterweight (9), the speed limit process is with last identical, and car (cage) (4) and primary and secondary can safe stop motions to weight average.
