Abstract
The utility model relates to a signal obtaining mechanism for traction type construction lifting and lowering device fixed point stop positions, which belongs to the technical field of control of a traction type construction lifting and lowering device. One segment of a steel wire between a friction wheel and a guide pulley of a transmission system of a traction machine is connected with a driven wheel in a tangential direction or in an envelope card mode. The periphery of the outer margin of the driven wheel is uniformly glued with a plurality of small magnets. The mobile steel wire can drive the driven wheel to rotate. A sensor which is arranged in the vicinity transports a sensed pulse signal to a pulse counter in an electric control box to carry out count and operation and reflects actual height of a hanging basket. Because the movable steel wire and the driven wheel do not have load so as to do not generate phenomenon of slipping and do not have measurement error, the control of the fixed point stop positions of the hanging basket is fairly precise.
Description
Technical field
The utility model relates to traction-type building hoist control technology field, and particularly a kind of traction-type building hoist fixed point off-position signal obtains mechanism.
Background technology
At present, in the traction-type building hoist, the signal of electric appliance control box 10 control hanging baskets 1 lifting fixed point off-position all obtains on brake wheel 7 or half a coupler 8 by sensor 11, promptly obtains in the driving system of its signal before friction wheel 5, referring to shown in Figure 1.But because afterbody transmission (rotatablely moving of friction wheel 5 becomes the straight-line motion of steel rope 3) is the traction transmission, it is to come transferring power by the friction force that is produced between friction wheel 5 and the steel rope 3.So in real-world operation, in the moment that motor 12 starts or stops, (being to mention normal speed zero moment or be kept to zero from normal speed moment promptly) from initial velocity, hanging basket 1 changes normal operating speed or hanging basket 1 in a short period of time from original quiescence to be stopped in a short period of time from normal operating condition, because steel rope 3 all has load all the time, so can occur slide relative (being commonly called as " skidding ") between friction wheel 5 and the steel rope 3, the signal head count value does not conform to hanging basket 1 actual height, and the appearance of this measured error causes hanging basket 1 fixed point off-position inaccurate.
Summary of the invention
The technical problems to be solved in the utility model is the actual height that the signal head count value will accurately reflect hanging basket, thereby realizes the accurate control to hanging basket fixed point off-position.
The technical solution that the utility model proposed is such: a kind of traction-type building hoist fixed point off-position signal obtains mechanism, comprise the traction motor 12 in the traction driving system, half a coupler 8, brake wheel retarder 7, friction wheel 5, steel rope 3, leading sheave 4, counterweight 2, hanging basket 1, and sensor 11, lead 9 and electric appliance control box 10, steel rope 3 one ends tie hanging basket 1, its other end is walked around a plurality of leading sheaves 4 successively, tie counterweight 3 behind the friction wheel 5, on described steel rope 3, be connected with follower 13, this follower 13 outer marginal circumferences one side is uniform to be pasted with one group of small magnet 14, at follower 13 contiguous and with small magnet 14 opposite positions on be provided with sensor 11, its output pulse signal is transported to pulse totalizer in the electric appliance control box 10 by lead 9.Described follower 13 outer marginal circumference central authorities are pressed in steel rope 3 one sides and do tangential the connection.Described follower 13 outer marginal circumference central authorities are pressed in steel rope 3 inboards and make envelope and connect.Be provided with a pinch roller 15 in steel rope 3 inboards and do the envelope connection with it, this pinch roller 15 is connected with follower 13 by speed-changing mechanism.
Principle of work of the present utility model is: steel rope 3 drives follower 13 rotations during work, the impulse singla of sensing from the some little magnetic patch 14 of the uniform stickup of follower 13 outer marginal circumferences, through sensor 11, lead 9 is transported to electric appliance control box 10 interior pulse totalizers and is carried out step-by-step counting, when traction motor 12 starts moment, friction wheel 5 " skidding " occur with steel rope 3, friction wheel 5 begins to rotate, and steel rope 3 is still static, be that follower 13 and hanging basket 1 also remain static, have only when steel rope 3 athleticisms drive follower 13, hanging basket 1 enters state of kinematic motion simultaneously, and counting machine just begins counting.In like manner, when shutting down appearance " skidding ", steel rope 3 still can move, and counting machine is still highly counted the ascending, descending of hanging basket 1, thereby can realize the purpose that off-position is accurate.
Compared with prior art, the utility model since the pulse signal device that will reflect the hanging basket height be arranged on and the steel rope of traction driving system mutually on the position of crimping, this impulse singla obtains the actual height of hanging basket through the computing of pulse rolling counters forward, because follower does not have load, so driving when follower rotates, the steel rope of motion can not produce skidding, just there is not measured error yet, guaranteed the hanging basket off-position of accurately fixing a point, improved work efficiency.

The specific embodiment
By following embodiment the utility model is further elaborated.
Embodiment 1:
Referring to shown in Figure 2, tangentially be crimped with a follower 13 at the friction wheel 5 of traction driving system and the outside, a certain position of one section steel rope 3 between the adjacent leading sheave 4, uniformly on this follower 13 outer rims one side circumference be pasted with six small magnets 14, sensor 11 is contained in follower 13 outsides, its induction mouth aligns small magnet 14 and keeps certain distance, as long as steel rope 3 motions, will drive follower 13 rotates, by lead 9 sensor 11 being sensed impulse singla input electric cabinet 10 interior pulse totalizers counts and computing, immediately reflect hanging basket 1 actual height of living in, realize accurately the fix a point control of off-position of hanging basket.
Embodiment 2:
Referring to shown in Figure 3, both sides are respectively equipped with a leading sheave 4 and a follower 13 below friction wheel 5, and steel rope 3 all twined this two-wheeled, become the envelope connection mode.Rotate when steel rope 3 motions will drive follower 13, other structure functions are identical with example 1.This routine structure also can realize accurately the fix a point control of off-position of hanging basket.
Embodiment 3:
Referring to shown in Figure 4, for making hanging basket fixed point off-position more accurate, how uniform small magnet 14 can be set on follower 13 outer marginal circumferences, and follower 13 will be done greatlyyer this moment, directly be connected on the steel rope 3 relatively more difficult, for this reason, an available less pinch roller 15 replaces follower shown in Figure 3, drives follower 13 motions that are positioned at steel rope 3 outsides, i.e. steel rope 3 motions by speed reduction gearing again, the also corresponding rotation of follower 13, thus reach the accuracy control of hanging basket fixed point off-position.
