Description

The tension member of elevator
Technical field
The present invention relates to elevator device, more specifically, relate to the tension member of this class elevator device.
Background of invention
Conventional tractor elevator system comprises that gondola, balancing weight, two or many connect gondola and the hawser of balancing weight, the hauling block of mobile hawser and the machinery that hauling block is rotated.Hawser is to be made by the steel wire of stranded or twisted, and pulley is made by cast iron.Machinery can be gear-driven, and is also can right and wrong gear-driven.Gear-driven machinery allows the higher motor of operating speed, and this motor is compact, and price is lower, but needs extra maintenance and space.
Though proved that conventional circular steel hawser and cast iron pulley are very reliable, and be that cost is effective that their use is had some restrictions.One of these restrictions are the tractive force between hawser and the pulley.Increase the cornerite of hawser or on pulley, open some grooves, can improve these tractive force.Yet owing to increase the result of wearing and tearing (cornerite) or increase hawser pressure (fluting), these two kinds of technology have all reduced the durability of hawser.Improving the another kind of method of tractive force, is to use the lining of being made by synthetic material in the groove of pulley.Lining can increase the coefficient of friction between hawser and the pulley, and simultaneously the wearing and tearing of hawser and pulley is reduced to minimum.
Another restriction to use circular steel hawser is the flexible and fatigue properties of round wire rope.Every steel wire rope of the safety standard requirements of elevator has minimum diameter d (to CEN (European standard coordination board), d now Minimum=8mm is to ANSI (American National Standards Institute), d MinimumThe D/d ratio of=9.5mm (3/8 ")) and tractor elevator is more than or equal to 40 (D/d 〉=40), and wherein D is the diameter of pulley.This makes diameter of pulley D be 320mm (is 380mm to ANSI) at least.Diameter of pulley D is big more, and the moment of required driving elevator device machinery is also big more.
Another shortcoming of conventional circular hawser is that the pressure of hawser is big more, and the life-span of hawser is just short more.When hawser on pulley by the time produce the pressure (P of hawser Hawser), the pressure of hawser is directly proportional with tension force (F) in the hawser, with diameter of pulley D and the cable diameter d (P that is inversely proportional to Hawser≈ F/ (D/d).In addition, the shape of pulley groove increases the technology of tractive force comprising slotting and so on and also can improve the maximum hawser pressure that hawser bears on pulley.
Although existing above-mentioned technology, scientists and engineers but still carry out work under applicant's assignee's guidance, and exploitation drives the more effective and more durable method and apparatus of elevator device.
Disclosure of the present invention
According to the present invention, the flakiness ratio of elevator tension member (aspect ratio) is greater than 1, and the flakiness ratio here is defined as the width w of tension member and the ratio of thickness t (flakiness ratio=w/t).
Key property of the present invention is that tension member has flat property.The increase of flakiness ratio can make tension member have the mating surface that is limited by width dimensions, makes the distribution optimization of hawser pressure.Therefore, make the interior maximum pressure minimum of tension member.In addition, by increasing flakiness ratio (equal with respect to flakiness ratio 1 circular hawser), can when keeping the tension member cross-sectional area constant, reduce the thickness of tension member.
According to the present invention, tension member also comprises many independent loading rope, strand and/or steel wires that are contained in the public clad.Clad separates each rope, strand and/or steel wire, and the boundary defines the mating surface of engagement hauling block.
Because the structure of tension member, the pressure of hawser can distribute on whole tension member more equably.Therefore, compare, reduced the maximum pressure of hawser significantly with conventional cable type elevator with same loading capacity.And, for identical loading capacity, reduced the effective diameter ' d ' (on bending direction, measuring) of hawser.Therefore, under the situation that does not reduce the D/d ratio, can obtain less diameter of pulley ' D ' value.In addition, diameter of pulley D being reduced to minimum can use lower, the compact more high-speed motor of price as driving device under the situation that does not need gear-box.
Rope in the tension member of the present invention, strand and/or steel wire preferably adopt the multiple combining form of steel and organic fiber.These two kinds of materials can be safeguarded respectively, and comprise extraordinary steel cable and organic fiber rope in public shell; These two kinds of combinations of materials can be become a rope, have many these ropes to be dispersed in the public shell; In public shell, a kind of in these materials is arranged in order be enclosed in alternative around; Organic fiber can irregularly be dispersed in the public shell, and steel cable also can be dispersed in the public shell.
The combination that each is mentioned all forms a kind of hybrid flexible flat tension member, and this member has unexistent intensity and advantage in the flat tension member of the flat tension member of steel cable or organic fiber.Every kind of material all has advantage separately, and the advantage of steel comprises: have the nondestructive test performance; The heat resistance height; Low with tensile property.The advantage of organic fiber comprises: in light weight, and the intensity height; Insensitive to corroding.When reality adopts steel and organic fiber to make tension member, share under the situation of loading at these two kinds of materials, can make the tension member that performance significantly improves.The invention provides several embodiments, each embodiment is all shared loading by these two kinds of materials, need consider the loading capacity of every kind of material when sharing loading; Every kind of long-term bending fatigue resistance of material; The stability of the tensile property of every kind of material and the belt track when reaching this synergy.
