Description
Technical field
The applied technical field of detection in the elevator that the present invention relates to respond in the time of irregular operating state, fault correction or safety device, particularly relates to a kind of position-adjustable and has the vertical swelling device of elevator of dodging space.
Background technology
In the practical application of elevator, conventional cantilever swelling device comprises the cantilever that stretches out from guide rail, be arranged on hold-down arm on cantilever rotationally, be contained in rope wheel component on hold-down arm, rotate the pouring weight that is arranged on rope wheel component below.In the time that steel rope occurs to extend, under the Action of Gravity Field of pouring weight, hold-down arm rotates with respect to cantilever, moves downward tensioning steel rope with rope wheel component and pouring weight.But the position of this swelling device can not arbitrarily regulate, elevator expansion apparatus from guide rail away from or when overhead high, need to, by accessory equipment, for example, add long cantilever or set up base between swelling device and ground.Increase equipment has not only improved elevator use cost greatly, and make swelling device structure numerous and diverse, also strengthened mounting arrangements difficulty.In addition, after increase equipment, swelling device takes up room greatlyr, is not suitable for the situation that pit is less, thereby the use of elevator has been brought to larger restriction.In addition, because needs increase equipment according to condition, hoistway space is not of uniform size, and velocity limiter installation site is different apart from far and near apart from guide rail, so swelling device can not standardized production.Above these be all elevator use, install and brought great inconvenience.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of easy and simple to handle, position can arbitrarily regulate, need not increase accessory equipment, simple in structure, take up room little, use cost is low, and can carry out the position-adjustable of standardized production and there is the vertical swelling device of elevator of necessarily dodging space.
Position-adjustable of the present invention and there is the vertical swelling device of elevator of dodging space, comprise weight parts, bracket component, described weight parts comprise the pouring weight that two front and back are arranged symmetrically with, between described two pouring weights, be fixedly equiped with rope sheave, wirerope-winding is on described rope sheave, before and after the wheel disc of described rope sheave and described pouring weight, be arranged in parallel, the bottom of described two pouring weights is fixed together
Be positioned on the lateral surface of described pouring weight at rear portion and be fixed with switch, the switch contact on described switch stretches out left, and the outside of described two pouring weights is equiped with respectively two guideposts that distribute up and down,
Described bracket component comprises front frame, after poppet and the horizonal base plate fixing on the ground, described front frame, the bottom of after poppet is fixed on described base plate, described front frame, the middle part of after poppet is equipped with the guide groove to downward-extension, described guidepost is positioned at described guide groove and can slides up and down along described guide groove, two spacers that distribute up and down are also threaded on described after poppet, the two ends up and down that the vertical switch of arranging re-packs are separately fixed on the follower head of described two spacers, the middle part of the right lateral surface that described switch re-packs is plane, top, bottom is cancave cambered surface, described switch contact is positioned at the length range d of described right lateral surface.
Swelling device difference from prior art of the present invention is the swelling device that the present invention has adopted weight parts, bracket component to match, on weight parts, be fixedly installed switch, switch is set on bracket component to re-pack, when steel rope tractive weight parts up-and-down movement, the apparent motion that switch contact on switch re-packs along switch, in the time moving to top cancave cambered surface or bottom cancave cambered surface, switch contact is pushed by cancave cambered surface, elevator thereby be de-energized stop.
Swelling device of the present invention can arbitrarily move and fix on the ground according to the position at speed limiter wire rope place, the size that need not increase accessory equipment or change cantilever, is specially adapted to the situation that elevator hoistways is narrow, pit is more shallow, traditional swelling device is inconvenient to install.In addition, this apparatus structure is simple, it is little to take up room, use cost is low, and can normalisation batch manufacturing, for installing and using of elevator provides a great convenience.
Position-adjustable of the present invention and there is the vertical swelling device of elevator of dodging space, the center of wherein said rope sheave is not on the line of centers of described pouring weight, and described rope sheave leans out the outer part of described pouring weight to the right.Before and after rope sheave leans out and makes rope sheave, both sides produce certain space of dodging, the miscellaneous part that car bottom girder is installed from then on space is passed down through and can produce interference, car thus can move downwards darker, therefore, this device is particularly useful for the hoistway that pit is more shallow.
Position-adjustable of the present invention and there is the vertical swelling device of elevator of dodging space, wherein said front frame, after poppet are " L " shape and front and back are arranged symmetrically with, and the minor face of described front frame, after poppet is all fixed on described base plate." L " support stability is higher, is difficult for rocking when stressed, has ensured the operation precision of associated components, has improved the effect of swelling device.
Position-adjustable of the present invention and have the vertical swelling device of elevator of dodging space, wherein said base plate fixes on the ground by expansion bolt.Adopt expansion bolt that bracket component is firmly fixed on the ground, further improved the stability of bracket component.
Position-adjustable of the present invention and have the vertical swelling device of elevator of dodging space, wherein said rope sheave is installed between two pouring weights by threaded shaft.Adopt threaded shaft that rope sheave and pouring weight are removably fixed together, it is convenient to connect reliably, install and remove, and has improved swelling device installation effectiveness.
Below in conjunction with accompanying drawing to position-adjustable of the present invention and there is the vertical swelling device of elevator of dodging space and be described further.
