Description
Technical field
The present invention relates to a kind of position detecting device, especially a kind of position detecting device that is used for the elevator level control system that is applicable in the high-building construction process.
Background technology
Building hoist is an indispensable vertical transport instrument in the high-building construction; But the elevator of place in operation does not have the automatic leveling function mostly at present; Minority has the elevator of flat bed controllable function also to exist the not high defective of langding accuracy; And, cause former control box crawl infringement electric controling element repeatedly because flat bed is inaccurate.
Facts have proved the really degree of the cage position signal that the decisive factor of langding accuracy is to collect.Be employed at present on the elevator arbor and install one and revolve and pass coder and straight-line displacement is converted into angle metric mode gathers the cage position signal; But because the size of wirerope diameter can not ignore; Causing the thickness that is wrapped in the steel rope on the winch to increase gradually, no longer is simple linear relationship between cage rise height and the angle displacement, and can't portray with the corresponding relation of confirming; When therefore transferring straight-line displacement to angular metric, can produce very mistake.This structure and sensor arrangement will have a strong impact on langding accuracy, and more past high-rise error is big more, not be suitable for the level control system of high-building construction.
Summary of the invention
Technical matters: the objective of the invention is to overcome the deficiency in the prior art, provide a kind of simple in structure, measure the position detecting device that accurate, easy to operate building hoist level control system is used.
Technical scheme: the position detecting device that is used for the elevator level control system of the present invention; Comprise framework, photoelectric encoder, be located at the preceding pinch roller and the back pinch roller of both sides before and after the steel rope; Preceding pinch roller is located on the front wheel spindle, and back pinch roller is located on the hind axle, and forward and backward wheel shaft is parallel to be located on the framework; Through the distance of slack-free spring maintenance with front wheel spindle, the end of front wheel spindle is associated with photoelectric encoder through coupler to the two axial ends of hind axle respectively.
Described framework comprises the two block frame plates that laterally arrange; Two block frame plates are provided with the forward and backward fixed link that is fixed together; Be provided with the sleeve pipe that is sleeved on the fixed link of back between the two block frame plates; Be arranged with the fixedly open-work and the open-work that wears hind axle of front wheel spindle bearing seat on the two block frame plates, the wheelbase direction that wears the forward and backward wheel shaft in open-work edge of hind axle has sliding tray.
The middle part of pinch roller and back pinch roller is provided with the grooving of surface attachment glue-line before said.
Beneficial effect: position detecting device of the present invention mainly is made up of front and back pinch roller, spring, photoelectric encoder, coupler etc.The axle of preceding pinch roller and the axle of photoelectric encoder link to each other with coupler, and the effect of back pinch roller is to guarantee do not have slide relative between steel rope and the preceding pinch roller.When the motor drives reel moved steel rope, steel rope passed through in the middle of two pinch rollers, owing to be the pure rolling contact between pinch roller and the steel rope, the distance that steel rope moves is exactly the distance that cage moves up and down.Therefore, the angle that the distance that cage moves can directly turn over through photoelectric encoder representes that cage position at any time just can show with the form of pulse exactly, and shows through level control system.Distance that the present invention utilizes the direct measuring steel wire of photoelectric encoder rope to pass by has overcome on the traditional measurement method error that the existence owing to wirerope diameter produces, and it is simple in structure, survey precision is high, the flat bed performance is good, has practicality widely.

The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
As depicted in figs. 1 and 2, position detecting device of the present invention mainly is made up of framework, preceding pinch roller 11, back pinch roller 16, spring 6, photoelectric encoder 7, coupler 8 etc.Described framework comprises the two block frame plates 1 that laterally arrange; Two block frame plates 1 are provided with the forward and backward fixed link 10,3 that is fixed together; Be provided with the sleeve pipe 2 that is sleeved on the fixed link 10,3 of back between the two block frame plates; Be arranged with the fixedly open-work and the open-work that wears hind axle 5 of front wheel spindle 9 bearing seats on the two block frame plates 1, the wheelbase direction that wears the forward and backward wheel shaft 9,5 in open-work edge of hind axle 5 has sliding tray 1-1; Comprise framework, photoelectric encoder 7, be located at both sides, steel rope 13 front and back preceding pinch roller 11 and the back pinch roller 16, preceding pinch roller 11 is mounted on the front wheel spindle 9 through key, bearing is equipped with at front wheel spindle 9 two ends, bearing embeds respectively in the bearing hole of two block frame plates 1; Back pinch roller 16 is located on the hind axle 5, opens bearing hole in the middle of the back pinch roller 16, is embedded with bearing 15, and bearing 15 inner rings are nested in the middle part of hind axle 5 again, and a side of bearing 15 is located with the shaft shoulder, and opposite side is with abutment sleeve 14 location; Insert respectively in the sliding tray 1-1 of two block frame plates 1 at hind axle 5 two ends, and the part that hind axle 5 stretches out frame plate 1 is installed with packing ring 4, and 1 of packing ring 4 and frame plate leave the gap, and packing ring 4 is locked on the hind axle 5 by nut outside; Forward and backward wheel shaft 9,5 parallel being located on the framework, the two axial ends of hind axle 9,5 is respectively equipped with the spring 6 of tension, and an end of front wheel spindle 9 stretches out the part of frame plate 1, is connected with photoelectric encoder 7 through coupler 8.In two block frame plates, 1 outside, the following position of front wheel spindle 9; Be fixed with coupling link 12 respectively, connect the spring 6 that is drawn on the coupling link 12, the other end of spring 6 is connected the end of hind axle 5; Because hind axle 5 is installed among the sliding tray 1-1 of frame plate 1; Under spring 6 tension, can guarantee the trend that front wheel spindle 11 and hind axle 5 have distance between shafts to reduce, before making pinch roller 11 and back pinch roller 16 constantly all with steel rope 13 closed contacts; Back fixed link 3 passes two block frame plates 1, and the centre is coated with sleeve pipe 2, and sleeve pipe 2 two ends head on the inboard of two block frame plates 1, and with the spacing of fixing two block frame plates 1, back fixed link 3 passes two ends of frame plate 1, through nut locking; Preceding fixed link 10 has been accomplished the fixing of frame plate 1 spacing, so use nut locking after only need passing frame plate 1 because the bearing on the front wheel spindle 9 has embedded in the bearing hole of frame plate 1.Pinch roller 11 has grooving with the middle part of back pinch roller 16 before said; The surface attachment of grooving has glue-line; Can increase friction coefficient with steel rope 13; Before and after guaranteeing between pinch roller and the steel rope 13 for pure rolling contacts, like this distance that moves of steel rope 13 just with the corner of front wheel spindle 9 relation in direct ratio, and pass to photoelectric encoder 7 through coupler 8.Photoelectric encoder 7 is converted into impulse singla with angular signal, passes to level control system, through the processing of system, and the accurate displacement that can draw steel rope, and confirm in view of the above the position of cage to realize the accurate detection to the cage position.
