Description
Technical field
The utility model relates to a kind of dumb waiter corollary equipment, is specifically related to a kind of elevator be convenient to electric wire and folded.
Background technology
Dumb waiter is mainly used for the foreign material such as transporting food products, clothes.Compared to traditional riding elevator, the elevator of dumb waiter is usually less, car domestic shipping weight is generally lower than 500kg, it is lower to the requirement of safety and traveling comfort, therefore cost is also very low, and dumb waiter is widely used in the place that restaurant, hotel, market etc. need to transport foreign material between different buildings is referred to as.
The car of dumb waiter can arrange a lot of electric wires usually; such as light, signal; insulation is arranged; these electric wires carry out folding with the lifting of lift car; due to its made of soft; in order to avoid it is by steel rope extrusion damage; therefore can not reel with steel rope winch spool; existing method adopts an independent winding motor to reel; but extra winding motor not only cost is very high; the more important thing is that it is difficult to synchronous with steel rope winch spool, there is the situation that electric wire is pulled apart in occasional, brings unnecessary trouble.
Utility model content
The purpose of this utility model is that providing a kind of is convenient to the folding elevator of electric wire, and not only structure is simple, easy to use, and synchronism is good, and cost is low.
The folding elevator of electric wire is convenient in this programme, comprise lift car and the traction steel-cable and the electric wire that are arranged on lift car upper center position, described electric wire is arranged side by side, and electric wire is coated with banded housing, being folded with of described banded housing, its width is 70 ~ 80% of car width, the length of banded housing is greater than the degree of depth of elevator, the top of banded housing is fixed on elevator top, the center of banded housing fold is provided with through wires hole, the engineering plastics sliding sleeve that wear resisting property is good is provided with in this through wires hole, the cross-sectional plane of engineering plastics sliding sleeve is oval, described traction steel-cable is through engineering plastics sliding sleeve.
Adopt the elevator that electric wire folds of being convenient to of this programme to have following advantage: because electric wire is arranged side by side, and electric wire is coated with banded housing, so the bulk strength of electric wire can be larger, and banded housing makes electric wire more easily fold, because the center of banded housing fold is provided with through wires hole, the engineering plastics sliding sleeve that wear resisting property is good is provided with in through wires hole, the cross-sectional plane of engineering plastics sliding sleeve is oval, described traction steel-cable is through engineering plastics sliding sleeve, banded housing can be made like this to fold along with the rolling of traction steel-cable, synchronism is good, and due to the existence of engineering plastics sliding sleeve, the friction of traction steel-cable and banded housing is less, not easily wear and tear banded housing and electric wire wherein, unitary construction is only change the arrangement mode of electric wire, eliminate traditional cord wrap motor, therefore structure is simpler, use more convenient.
Preferably, the material of described banded housing is antifriction rubber, and such design can make banded housing more durable, with the friction of traction steel-cable in can not damage.
Preferably, be provided with the steel rope distributed along its length in described banded housing, such design can make the tensile strength of banded housing better, breaks electric wire wherein after avoiding banded housing distortion.
Preferably, be provided with elastic drag rope between described adjacent engineering plastics sliding sleeve, in the process that such design can make lift car rise, banded housing can better reclaim and fold.
Accompanying drawing explanation
Fig. 1 is that the utility model embodiment is convenient to elevator that electric wire the folds structural representation at receiving state.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises, lift car 1, traction steel-cable 2, banded housing 3, engineering plastics sliding sleeve 4.
Embodiment be convenient to the folding elevator of electric wire as shown in Figure 1: comprise lift car 1 and be arranged on traction steel-cable 2 and the electric wire of lift car 1 upper center position, here electric wire comprises signal wire (SW) traditional in car, illuminating line and control line, electric wire is arranged side by side, and electric wire is coated with banded housing 3, the cross-sectional plane of banded housing 3 is round rectangle, its Inner extrusion covered electric cable, the material of banded housing 3 is antifriction rubber, the steel rope distributed along its length is provided with in banded housing 3, so banded housing 3 is not only more durable, and the tensile strength of banded housing 3 is better, electric wire is wherein broken after avoiding banded housing 3 to be out of shape, being folded with of banded housing 3, the width of banded housing 3 is preferably 70% of car width, be snapped in elevator in order to avoid fold into outside lift car 1, the length of banded housing 3 is greater than the degree of depth of elevator, the top of banded housing 3 is fixed on elevator top, the center that banded housing 3 folds is provided with through wires hole, the engineering plastics sliding sleeve 4 that wear resisting property is good is provided with in through wires hole, the cross-sectional plane of engineering plastics sliding sleeve 4 is oval, traction steel-cable 2 is through engineering plastics sliding sleeve 4, elastic drag rope (not shown) is provided with between adjacent engineering plastics sliding sleeve, in the process that such lift car 1 rises, banded housing 3 can be regained timely and fold under the effect of elastic drag rope, can be better than the effect utilizing separately gravity folding.
This programme to be convenient to the elevator that electric wire folds be work like this: electric wire is arranged side by side and is coated with banded housing 3, and the bulk strength of electric wire is large, not easy to wear, and what the schistose texture of banded housing 3 can make electric wire is more prone to folding, the good engineering plastics sliding sleeve 4 of wear resisting property is provided with in the through wires hole of the center that banded housing 3 is folding, traction steel-cable 2 is through after engineering plastics sliding sleeve 4, banded housing 3 can be made to carry out synchronous folding along with the rolling of traction steel-cable 2, oval engineering plastics sliding sleeve 4 makes traction steel-cable 2 less with the friction of banded housing 3, elastic drag rope can strain engineering plastics sliding sleeve 4, in the process that such lift car 1 rises, banded housing 3 can be regained timely and fold under the effect of elastic drag rope, and in the process that elevator declines, gravity can overcome the banded housing 3 that elastic drag rope pulling force makes to fold and be stretched.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in specification sheets etc. record the content that may be used for explaining claim.
