Abstract
The invention provides a traction type elevator, which comprises an elevator car, a counterweight filler, a traction belt and a traction wheel. The two ends of the traction belt are respectively connected with the elevator car and the counterweight filler, and the center portion of the traction belt is sleeved on the traction wheel. The traction belt comprises a plurality of branch ropes which are interval parallel arrangement. An outer casing layer is injection molded on the external of the branch ropes, and thus the plurality of branch ropes are integrated. An groove is arranged on the surface of the outer casing layer. The groove is formed on the interface of the adjacent two branch ropes, and the bottom surface of the groove is an arc surface. The traction wheel comprises a bulge which is matched with the groove. The traction type elevator is reasonable in structure. The fracturing and wearing because of uneven stress of the outer casing layer of the traction belt are avoided, and thus the scrapping of the whole traction belt because the branch ropes escape from the outer casing layer is avoided. The reliability of safe operation of the elevator is ensured.

Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of traction elevator one provided by the invention preferred embodiment;
Fig. 2 is the generalized section of the preferred embodiment of hoist ropes one shown in Fig. 1;
Fig. 3 is the generalized section of another preferred embodiment of hoist ropes shown in Fig. 1.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Referring to Fig. 1, is the structural representation of traction elevator one provided by the invention preferred embodiment.Described traction elevator 100 comprises lift car 1, to pouring weight 2, drawing belt 3, traction sheave 4 and towing machine (not shown).Described drawing belt 3 two ends connect described lift car 1 and respectively to pouring weight 2, middle part is set on described traction sheave 4, described towing machine drives described traction sheave 4 rotate and then drive drawing belt 3, makes lift car 1 and pouring weight 2 is done on cage guide to the crank motion of vertical direction.
Again incorporated by reference to consulting Fig. 2, it is the generalized section of the preferred embodiment of drawing belt one shown in Fig. 1.Described drawing belt 3 comprises the sub-rope 31 of many spaced and parallel arrangements.The volume sth. made by twisting direction of adjacent two root ropes 31 is contrary.Outside described son rope 31, be injected with surrounding layer 32, make many roots rope 31 be combined into flat row's shape entirety.Described son rope 31 shape of cross sections are rounded.Described surrounding layer 32 is arranged along the appearance profile of described son rope 31.Described surrounding layer 32 is prepared from by polyurethane or neoprene, can heat resistanceheat resistant, dirt, oil and moisture, ageing-resistant, there is the inner son rope 31 of protection, relax the effect of external impact.Two apparent surfaces of described surrounding layer 32 are symmetrically arranged with groove 33.Described groove 33 interval is arranged, and it is formed at the intersection of adjacent two root ropes 31, and the bottom surface of described groove 33 is arc surface.Groove 33 structure of described drawing belt 3 drawing belt 3 the is possessed effect of cingulum.Described traction sheave 4 comprises protruding 41.Described protruding 41 shape of cross section semicirculars in shape.Described protruding 41 match with the groove 33 of described surrounding layer 32, the two is occlusion mutually, increase the friction force between drawing belt 3 and traction sheave 4, traction effect significantly improves, and due to groove 33 bottom surface of described drawing belt 3 be arc surface, the projection 41 of described traction sheave 4 matches with groove 33, the application force of projection 41 pairs of groove 33 inwalls of traction sheave 4 is uniformly distributed, avoid the surrounding layer 32 of drawing belt 3 because of discontinuity cracking wear, thus avoid son rope 31 surrounding layer 32 of escaping out that whole drawing belt 3 is scrapped, ensure that the reliability of elevator safety operation.
In the present embodiment, described son rope 31 comprises a central strand 311 and wraps the many outer layer strand 312 of twisting with the fingers in described central strand 311 periphery.Wherein, described central strand 311 is compiled sth. made by twisting by several carbon fiber and is formed, each outer layer strand 312 is divided into three layers to compile sth. made by twisting by the identical steel wire of 19 diameters according to the mode that ground floor is from inside to outside 1 steel wire, the second layer is 6 steel wires, third layer is 12 steel wires forming, be point cantact between described steel wire.Described steel wire is galvanized steel wire.The diameter of described central strand 311 is greater than the diameter of described outer layer strand 312, is convenient to bending.
As the further improvement of above-mentioned embodiment, as shown in Figure 3, the central strand 311 ' of the sub-rope 31 ' of described drawing belt 3 ' is divided into three layers to compile sth. made by twisting by the identical steel wire of 19 diameters according to the mode that ground floor is from inside to outside 1 steel wire, the second layer is 6 steel wires, third layer is 12 steel wires forming, be point cantact between described steel wire, each outer layer strand 312 ' is compiled sth. made by twisting by several carbon fiber and is formed.Described steel wire is galvanized steel wire.The diameter of described central strand 311 ' is greater than the diameter of described outer layer strand 312 ', is convenient to bending.
The pulling force carried due to carbon fiber is 7 ~ 10 times of steel wire, and weight only has 1/4th of equal steel wire, therefore, described son rope is jointly compiled sth. made by twisting by carbon fiber and steel wire and is formed, not only can increase the load-carrying capacity of drawing belt, and the entire outer diameter of drawing belt can be reduced, reduce the deadweight of drawing belt.
Certainly, described son rope 31 also all can be compiled sth. made by twisting by several galvanized steel wire and form, or is all formed by several carbon fiber volume sth. made by twisting.
Compared to prior art, traction elevator provided by the invention is scientific and reasonable for structure, the surrounding layer of described drawing belt is provided with groove, the bottom surface of described groove is arc surface, described traction sheave is provided with the projection with described groove match, the two is occlusion mutually, increase the friction force between drawing belt and traction sheave, traction effect significantly improves, and due to the groove floor of described drawing belt be arc surface, the application force of the projection of traction sheave to groove inner wall is uniformly distributed, avoid the surrounding layer of drawing belt because of discontinuity cracking wear, thus avoid son rope surrounding layer of escaping out that whole drawing belt is scrapped, ensure that the reliability of elevator safety operation.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
