Summary of the invention
The purpose of this utility model is to provide a kind of space-saving elevator speed limiter wire rope swelling device.
In order to reach above purpose, the technical solution adopted in the utility model is: a kind of elevator speed limiter wire rope swelling device, comprise the stay bearing plate that is installed on the cage guide, axle, be installed in the expansion tightening wheel on the described axle, walk around described expansion tightening wheel and upwardly extending steel rope, electric switch, clump weight, described stay bearing plate offers guide groove on vertically, described axle horizontal setting, and can vertically be inserted in slidably in the described guide groove, has the locating part that is used to forbid described axle rotation on the described guide groove, bag is provided with protective cover on the described expansion tightening wheel, described protective cover is connected on the described axle, has contact on the described protective cover, being with described expansion tightening wheel and described protective cover when described axle moves downward to described guide groove when terminal, described contact touches described electric switch, upper fixed at described expansion tightening wheel on the described protective cover has described clump weight, and described clump weight is around between the steel rope of described expansion tightening wheel both sides.
Have bending edges on the described protective cover, this bending edges has formed described contact.
The part that described axle is inserted in described guide groove is square, and the cell wall of described guide groove has formed described locating part.
Be with the collar on the part that is square on the described axle, described axle is inserted in the described guide groove by the described collar.
Described electric switch is installed on the described stay bearing plate, is positioned near the described guide groove end.
Offer at least two bayonet sockets on the described protective cover, described at least two bayonet sockets are stuck on the described axle.
Because the utility model has adopted above technical scheme, its advantage is: around the space between the steel rope of expansion tightening wheel both sides is idle, by clump weight is placed on expansion tightening wheel above, be positioned in the middle of the steel rope of expansion tightening wheel both sides, make full use of free space, thereby can save hoistway space, reduce building cost.
Description of drawings
Accompanying drawing 1 is a block diagram of the present utility model;
Accompanying drawing 2 is looked scheme drawing for master of the present utility model.
The specific embodiment
Further set forth concrete structure of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1-2; a kind of elevator speed limiter wire rope swelling device; comprise the stay bearing plate 1 that is installed on the cage guide 2; axle 6; be installed in the expansion tightening wheel 5 on the axle 6; walk around expansion tightening wheel 5 and upwardly extending steel rope 9; electric switch 4; clump weight 10; stay bearing plate 1 is installed on the cage guide 2 by pressing guide plate 3; stay bearing plate 1 offers guide groove 11 on vertically; axle 6 is horizontally disposed with; and can vertically be inserted in slidably in the guide groove 11; in Fig. 1; stay bearing plate 1 comprises front and rear panel; formed the space of accommodating expansion tightening wheel 5 between the front and rear panel; on front and rear panel, all offer guide groove 11; the both ends of axle 6 are inserted in respectively in the guide groove 11; expansion tightening wheel 5 is equipped with by bearing in the centre of axle 6; has the locating part that is used to forbid axle 6 rotations on the guide groove 11; in Fig. 2; guide groove 11 is a square groove; the both ends of axle 6 are square respectively; squared ends on the axle 6 is with the collar; axle 6 is inserted in the guide groove 11 by the collar; the left and right sides cell wall of square groove has formed locating part; be used to forbid that axle 6 is along with expansion tightening wheel 5 rotates together; wrap regularly on the expansion tightening wheel 5 and be provided with protective cover 8; the effect of protective cover 8 is that expansion tightening wheel 5 is shielded; prevent that foreign matter from entering; in Fig. 1; offer bayonet socket on the protective cover 8; protective cover 8 is stuck on the axle 6 by bayonet socket; the rotation because axle 6 is under an embargo; then protective cover 8 can stably slide up and down with axle 6; has contact on the protective cover 8; the edge part that forms bayonet socket on the protective cover 8 outwards is bent to form bending edges 12; bending edges 12 has formed contact; electric switch 4 is installed on the stay bearing plate 1; be positioned near guide groove 11 ends; extend at steel rope; make that contact touched electric switch 4 when axle 6 had been with expansion tightening wheel 5 and protective cover 8 to move downward to guide groove 11 ends.Upper fixed at expansion tightening wheel 5 on the protective cover 8 has clump weight 10, and clump weight 10 is around between the steel rope 9 of expansion tightening wheel 5 both sides.Clump weight 10 can be equipped with Different Weight according to requirements such as hoisting depths.Steel rope 9 is to make the rotative speed of velocity limiter and elevator speed synchronous by swelling device, specifically, when steel rope takes place to extend, is being with expansion tightening wheel 5 to slide up and down and clump weight 10 by axle 6, can guarantee steel rope tensioner all the time.The effect of electric switch is to extend oversize when steel rope, cause expansion tightening wheel 5 when arriving end of travel, when moving downward to guide groove 11 terminal corresponding to axle 6, touch electric switch 4 by bending edges 12, thereby the operation of restriction elevator, the notice elevator service personnel is adjusted speed limiter wire rope 9, recovers the tensioner effect of this device.
