Description

Lift appliance

Technical field

Example of the present utility model relates to a kind of cage and is liftably arranged on the lift appliance this cage and control panel are electrically connected in hoist trunk and with lead-in wire.

Background technology

In the cage of elevator, be provided with the lead-in wire that electric wireline, control line are formed integrally as platypelloid type by employing clad material as shown in Japanese Unexamined Patent Publication 2009-126640.One end of this lead-in wire is installed in cage, and the other end is connected with control panel by the connection box be arranged in hoist trunk.Part between the two ends of this lead-in wire sags into U-shaped due to deadweight.Again, this lead-in wire is elongated accordingly with the length of the lifting travel of cage.Therefore, in the large lift appliance of lifting engineering being applicable to high-rise, lead-in wire is long but also large all not only.

Usually, in this lead-in wire, the line feeder total length of steel wire is all embedded integratedly by clad material together with above-mentioned electric wireline, control line.This line feeder supports the weight of the lead-in wire entirety of growing up, so have to have large to tensile strength.Again, along with the lifting of cage, the part high-speed mobile in the longitudinal direction of the aforementioned U-shaped of this lead-in wire, so line feeder also needs to have flexibility that can be corresponding with this alteration of form.

So far, line feeder all adopts steel wire.But in the lift appliance of super high rise building, the length of lead-in wire sometimes also can more than 1000m.Therefore, when adopting steel wire, produce its weight and also become large, the weight of lead-in wire causes the unbalance loading of cage to increase such problem.Again, also creating to keep above-mentioned flexibility, being difficult to increase steel wire diameter, the such problem of sufficient intensity cannot be obtained thus.

Utility model content

The utility model provides a kind of and is provided with softness, have sufficient intensity and the lift appliance of the lead-in wire of light weight.

Lift appliance involved by example of the present utility model is that cage can be arranged on the lift appliance this cage and control panel are electrically connected in hoist trunk, by lead-in wire up and down, it is characterized in that, electric power in described lead-in wire with or the conductor of signal and the line feeder that configures side by side with described conductor in the total length of described lead-in wire be formed integrally as platypelloid type by clad material, described line feeder is made up of carbon fibre.

According to example of the present utility model, by adopting, carbon fibre being shaped to funicular line feeder, the lead-in wire of ultralight amount and superhigh intensity can being formed, even if be applicable to the lift appliance of super high rise building, compared with existing steel wire, also can be configured to sufficient high strength and light weight.

Accompanying drawing explanation

Fig. 1 is the integrally-built figure of the lift appliance illustrated involved by an example of the present utility model.

Fig. 2 be to illustrate in an example of the present utility model the view in transverse section of lead-in wire that adopted.

Detailed description of the invention

Below, with reference to accompanying drawing, example of the present utility model is described in detail.

Fig. 1 illustrates that the entirety of the lift appliance involved by this example is formed.In FIG, lift appliance 10 has cage 15, and guide rail 22a, 22b that this cage 15 can be formed on the hoist trunk 11 in building up and down guide supporting.This cage 15 is connected with the same bob-weight 16 be liftably arranged in this hoist trunk 11 by main rope 14.

The Machine Room 12 on the top of hoist trunk 11 is provided with winch 13a, and on its main rope sheave 13, coiling has main rope 14.At the two ends of this main rope 14, be hung with cage 15 and bob-weight 16, the rotation along with the main rope sheave 13 of winch 13a is elevated driving by well-bucket shape.

In the downside of the downside of cage 15 and bob-weight 16, be provided with by the compensating rope sheave 17 being arranged at hoist trunk 11 bottom and compensate rope 18.This compensation 18 roles of restricting offset the change that the quality of main rope 14 occurs according to the position of cage 15.

Again, the lead-in wire 19 of general flat type hangs from cage 15.One end of lead-in wire 19 is connected with the connection box 20 be arranged in hoist trunk 11, is connected to not shown control panel by this connection box 20.In addition, also connection box 20 can not be set, and slim control panel is set in hoist trunk 11, one end of lead-in wire 19 is directly connected in this control panel.The other end of this lead-in wire 19 is fixed on the lower surface portion of cage 15.

Part between the two ends of this lead-in wire 19 sags into U-shaped due to deadweight.Again, the many wires 31,32 be made up of electric wireline or control line etc. and many line feeders 33 as shown in Figure 2, configure by the cross section of lead-in wire 19 side by side, utilize and are formed integrally as platypelloid type by made clad materials 34 such as having flexible resin material.In the total length of lead-in wire 19, line feeder 33 all configures side by side with wire 31,32.Further, this line feeder 33 adopts carbon fibre replace existing steel wire and form.

At this, as everyone knows, carbon fibre is the fiber be made up of carbon element as its title, and the content of carbon element is, containing the carbon element of more than 90% in the carbon fibre of standard elastic rate, contains the carbon element of substantially 100% in the carbon fibre of high resiliency rate.Essential element beyond carbon element is nitrogen.Carbon fibre scorches polyacrylinitrile (PAN) fiber or the such organic fiber of pitch fibers in an inert atmosphere, the element beyond carbon element departed from and makes.The PAN system carbon fibre that more than 90% of commercially available carbon fibre is is raw material with PAN fiber.In the balance of Performance and Cost Modeling, use difficulty etc., PAN system carbon fibre is more outstanding than asphalt series carbon fibre.

The strong point of carbon fibre is all high-strength light in any case.Proportion, about 1.8, compared with 7.8 of iron, is about 1:4, compared with 2.5 of 2.7 or glass fibre of aluminium, is also obviously lighter material.And intensity and spring rate are also fine, pulling strengrth is roughly 10 times of iron divided by the strength-to-density ratio of density, and tensile elasticity rate is roughly 7 times of iron divided by the ratio spring rate of density, both very excellent.And, the material that still have the various characteristic such as not tired, non-corrosive, chemical heat are stablized, that characteristic also can be stable chronically under harsh condition reliability is high.

So elongated funicular carbon fibre that is shaped to is made line feeder 33.The quality of the line feeder 33 made by this carbon fibre and steel wire are in a ratio of light weight.Again, its intensity is different according to kind, but also can be 3500N/mm ², sufficient intensity can be obtained compared with existing steel wire.That is, as mentioned above, carbon fibre light weight and flexibility, the fatigability of resistance to flexing are excellent, being shaped to funicular line feeder 33 by forming by carbon fibre, can obtaining the lead-in wire 19 of the superhigh intensity of ultralight amount.

Example of the present utility model is illustrated, but this example is only as an example, not there is the intention of the scope limiting utility model.Its new embodiment can be implemented by other various forms, can carry out various omission, displacement, change in the scope not exceeding utility model purport.While these examples and its distortion are included in the scope of utility model or purport, be also contained in utility model described in claims and with in the scope of its equalization.
