Description

Elevator hoisting rope for high-rise building

Technical Field

The utility model relates to a tow formula elevator is with towline, concretely relates to high-rise building elevator towline.

Background

At present, a plurality of circular independent steel wire ropes are mostly adopted by a traction type elevator as metal traction ropes for the traction type elevator, and the steel wire ropes are very easy to twist in the installation process of the elevator, and each steel wire rope is formed by a multi-strand knob, so that the twisting of a single steel wire rope is not easy to find in the installation process, but the twisting is one of the main factors for reducing the service life of the steel wire rope. The abnormal torsion damages the original tightness of the steel wire rope and the lay length of the steel wire rope, so that the abrasion and fatigue are more easily aggravated, and the service life of the steel wire rope is further shortened. In order to solve the problems, a method of coating a marking line on the surface of the steel wire rope is adopted, but the marking line is easy to be worn off in the installation and transportation processes of the steel wire rope and cannot play a marking role.

In addition, since a single wire rope is limited in bearing capacity, particularly, a smaller wire rope is required to be used in order to reduce the diameter of the traction sheave, and therefore, a larger number of wire ropes must be used. Furthermore, since the strength of the single hoisting rope is reduced by using the multi-strand wire knob made of the non-metal material, the number of the non-metal hoisting ropes needs to be increased to improve the overall strength. With the increase of the number of the metal or nonmetal hauling ropes, it is very difficult to adjust the tension of all the hauling ropes to be consistent, and the uneven stress of the single hauling rope can cause the tension of the single hauling rope to be increased, thereby accelerating the fatigue fracture of the single hauling rope.

Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will explain specific embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and for a person skilled in the art, other drawings and other embodiments can be obtained without inventive effort, and the invention is not limited to this example.

Please refer to fig. 1 to 4. The high-rise building elevator hoisting rope provided by the embodiment of the utility model comprises a hoisting rope 1 which is formed by twisting a plurality of strands of wires into a rope, wherein the hoisting rope 1 is provided with a clamping piece 2, the clamping piece 2 is provided with a plurality of flexible clamping bodies 3, and an arc-shaped clamping groove 4 is formed between two adjacent flexible clamping bodies 3; the rope bodies of the hoisting ropes 1 can be clamped into different arc-shaped clamping grooves 4 of the clamping piece 2 to form a hoisting rope group; the clamping piece 2 is also provided with two cover plates 5, and the two cover plates 5 are provided with through holes 6 for the hoisting ropes 1 to pass through.

Supplementary explanation, the flexible clamp 3 refers to a flexible body which is arranged around the clamping piece 2 and used for forming an arc-shaped clamping groove 4 to clamp and fix the hauling rope 1, the flexible clamp 3 has certain rigidity to keep stable structure and certain flexibility to deform, concretely speaking, the flexible clamp 3 is formed into a shape which is generally stable, and meanwhile, after the rope body of the hauling rope 1 is clamped into the arc-shaped clamping groove 4, the flexible clamp 3 can deform after being extruded and can be recovered subsequently; when the specific flexible clamp body 3 is arranged on the clamping piece 2, the flexible clamp body 3 can be made of any commodity or material which is sold at will in a mode of injection molding with the clamping piece 2, and the requirements can be met.

It should be understood that when the flexible clamp body 3 clamps the hauling rope 1 through the arc-shaped clamping groove 4, the middle parts of the two side walls of the arc-shaped clamping groove 4 are relatively thin, so that the flexible clamp body 3 can be conveniently deformed to extrude and tighten the hauling rope 1.

Please refer to fig. 1 and 4 again. In this embodiment, the arc-shaped slot 4 may include two guiding portions 41 and two expanding portions 42 connected in sequence, the two expanding portions 42 are used to form an expanding cavity that is gradually narrowed along the rope body inserting direction of the hoist rope 1, the two guiding portions 41 are used to form a guiding cavity that is gradually widened along the rope body inserting direction of the hoist rope 1, and the rope body of the hoist rope 1 can be gradually inserted into the expanding cavity formed by the two expanding portions 42 in the arc-shaped slot 4 along the two guiding portions 41.

It should be further noted that, when the rope body of the hoist rope 1 is not started to be clamped, a gap left between the two guiding portions 41 (i.e. the two sides of the two flexible clamping bodies 3) of the arc-shaped clamping groove 4 is very small, and the enlarged cavity formed by the two enlarged portions 42 of the arc-shaped clamping groove 4 is also small, after the rope body of the hoist rope 1 is started to be clamped, the two guiding portions 41 are extruded to move towards the two sides until the rope body of the hoist rope 1 is completely clamped or most of the hoist rope is clamped into the enlarged cavity, the two guiding portions 41 can be contracted from the extruded state to the initial state to complete the wrapping and clamping limitation of the rope body of the single hoist rope 1, and meanwhile, the two enlarged portions 42 also generate a large extrusion force on the rope body of the hoist rope 1, and the static friction force between the two portions is large, so that the hoist rope 1 is not easy to twist.

Please refer to fig. 1 again. In this embodiment, a screw (not shown in the drawings) may be further included, the cover plate 5 is provided with a first threaded hole 51 for screwing the screw, and the clip member 2 is provided with a second threaded hole 52 for screwing the screw, which has the following advantages: realize being fixed in joint spare 2 with two apron 5 detachablelies on, be convenient for change joint spare 2 after dismantling two apron 5.

In addition, in another embodiment of the cover plate 5, the central portion of the cover plate 5 may be welded to the central portion of the clamping member 2, so that the hoisting ropes 1 can pass through the through holes 6 of the cover plate 5, and the plurality of hoisting ropes 1 constituting the hoisting rope group can be limited.

Please refer to fig. 3 again. In this case, the inner wall of the arc-shaped slot 4 may be provided with a flexible protrusion (not shown in the figure), which has the following advantages: the flexible protrusions are provided to increase the contact area of the flexible clamp body 3 with the hoist rope 1 and increase the static friction force therebetween.

Please refer to again. In this embodiment, the clip member 2 may be a cylindrical clip member, which has the advantage that the clip member 2 is more smooth and convenient to use compared with other shapes according to the environmental requirements and requirements. More specifically, the engaging member 2 is moved or slid on the groove of the sheave engaged with the hoist rope 1.

In this case, the inner wall of the through hole 6 may be provided with a metal ring (not shown), which has the following advantages: the metal ring is used for reducing the friction between the rope body of the hauling rope 1 and the through hole 6 of the cover plate 5 and prolonging the service life of the hauling rope and the through hole.

Please refer to fig. 1 again. In this case, the cover plate 5 can be implemented as a hemispherical cover plate (not shown) (similar to a bullet) or a truncated cone, which has the advantages of being more smoothly designed and having no corners, and being used with the clamping member 2, so that the clamping member 2 can be used with a pulley.
