Detailed description of the invention
As shown in Figure 1, the utility model position-adjustable and there is the vertical swelling device of the elevator of dodging space comprise weight parts, bracket component, composition graphs 4 again, shown in Fig. 5, weight parts comprise the pouring weight 2 that two pieces of front and back are arranged symmetrically with, rope sheave 1 is equiped with between two pouring weights 2, steel rope 11 is wrapped on rope sheave 1, be arranged in parallel before and after the wheel disc of rope sheave 1 and pouring weight 2, the middle part of two pouring weights 2 is provided with tapped bore, threaded shaft 6 passes the center of tapped bore and rope sheave 1 from back to front, rope sheave 1 is installed between two pouring weights 2, the bottom of two pouring weights 2 is fixed together.Again shown in composition graphs 2, the bottom of two pouring weights 2 can be fixed by the spacing connection post 21 between bolt and pouring weight, makes there is a space between two pouring weights 2, in addition, the relative position connecting latter two pouring weight 2 just secures, and does not have relative rotation, improves stability.The lateral surface being positioned at the pouring weight 2 at rear portion is fixed with switch bracket 3, switch bracket 3 is fixedly installed switch 4, switch contact 41 on switch 4 stretches out left, and the concrete structure of switch bracket 3, switch 4, switch contact 41 and mounting means, with reference to routine techniques means, do not repeat herein.The outside of two pouring weights 2 is equiped with two guideposts 5 distributed up and down respectively.
Again shown in composition graphs 6, Fig. 7, the front frame 71 arranged before and after bracket component comprises, after poppet 72 and the horizonal base plate 10 fixed on the ground by expansion bolt 11, the bottom of front frame 71, after poppet 72 is fixed on base plate 10, the middle part of front frame 71, after poppet 72 is equipped with the guide groove 701 to downward-extension, after poppet 72 is also threaded two spacers 9 distributed up and down, spacer 9 is positioned at the right side of guide groove 701, and perpendicular to after poppet 72.Again shown in composition graphs 8, bracket component also comprises the switch be vertically arranged on after poppet 72 and re-packs 8, switch re-pack 8 two ends be up and down separately fixed on the follower head of two spacers 9, switch re-pack 8 the middle part of right lateral surface be plane 802, top, bottom are cancave cambered surface 801, and switch contact 41 is positioned at the length range d of right lateral surface.Spacer 9 re-packs to switch and 8 provides a place of installing, and it is 8 far and near apart from after poppet 72 identical with switch contact 41 that switch is re-packed, the two can about align so that switch contact 41 can with switch re-pack 8 right lateral surface contact.Preferably, above-mentioned support is " L " shape and front and back are arranged symmetrically with, and wherein, forward, backwards, the minor face of two supports is all fixed on base plate 10 minor face of after poppet 72 minor face of front frame 71.
Again shown in composition graphs 2, Fig. 3, the utility model position-adjustable and the principle of work with the vertical swelling device of the elevator of dodging space are: weight parts, bracket component are installed together, whole guidepost 5 is made all to enter in guide groove 701, under normal condition, the plane 802 that switch contact 41 and switch re-pack on 8 contacts, and switch contact 41 not pressurized normally stretches out.During steel rope 11 tension, rope sheave 1 is pulled upward movement, guidepost 5 on drive pouring weight 2 is along guide groove 701 upward sliding, namely whole weight parts move straight up along guide groove 701, and then drive switch 4 upward movement together, when switch 4 move to switch re-pack 8 top time, switch contact 41 is extruded retraction by the re-pack cancave cambered surface 801 on 8 tops of switch.Otherwise when steel rope 11 crosses pine, weight parts move down, and switch contact 41 is extruded retraction by the cancave cambered surface 801 of bottom.After switch contact 41 is retracted, safety return circuit power-off, elevator is by stop.
Especially, as shown in Figure 1, the center of rope sheave 1 is not on the line of centers of pouring weight 2, rope sheave 1 leans out the outer part of pouring weight 2 to the right, this creates the terminal as shown in Figure 3 be positioned on front side of rope sheave 1 or rear side dodge space 200, from then on the miscellaneous part that car bottom girder is installed can be passed down through and can not produce interference in space, and it is darker that thus car can run downwards, and the elevator installation more shallow for pit provides a great convenience.
In sum, swelling device of the present utility model be directly be fixedly connected on ground, can arbitrarily place according to actual needs, break away from the constraint of relative position between rope sheave and guide rail, and, this apparatus structure is simple, it is little to take up room, for installing and using of elevator provides a great convenience.In addition, this device is easy and simple to handle, action is accurate, power-off is rapid, tensioner better effects if.
Above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
