Abstract
The invention discloses a component of an elevator lift car, and particularly relates to an elevator lift car guide shoe which comprises a metal guide shoe body. The elevator lift car guide shoe is characterized in that the inner surface of the metal guide whole body is covered by a Teflon layer. The elevator lift car guide shoe achieves the technical purposes that the elevator lift car guide shoe of a fire elevator system is high-temperature resistant, and friction noise is avoided. When the elevator lift car guide shoe slides up and down outside an elevator lift car guide rail, large noise can not be generated due to friction of the guide shoe and the guide rail, and due to the fact that the Teflon layer can be continuously and stably used within 240-260 DEG C, a fire elevator lift car system adopting the elevator lift car guide shoe can stably and safely operate in fires.
Description
Technical field
The present invention relates to a kind of parts of lift car, particularly a kind of lift car is led boots.
Background technology
In an elevator device, can be widely used guide assembly, for example lift car sliding up and down in hoistway just will depend on guide assembly and just can be achieved, and in the guide assembly of lift car, comprises and leads boots, and it plays directional tagging to sliding up and down of car.
Occurred on the market that at present multi-form lift car leads boots, for example, in the Chinese patent literature of bulletin that the patent No. is 200910233175.6, just provide a kind of self-lubricating nylon guide roller free of refueling, comprise that base plate, the disjunctor by nylon material, made are connected to the wallboard of base plate both sides, the section that described base plate and two wallboards form takes the shape of the letter U.Due to nylon material there is light weight, there is not corrosion, have certain elasticity and can be not cracked etc. characteristic, the base plate of leading boots in above-mentioned adopts nylon material to make, therefore possessed the self-lubricating of realization, exempted to refuel, the advantage such as the good and long service life of resistance to abrasion simultaneously, it is in service easy to wear that the lift car that has solved traditional metal material and be body, peripheral hardware polyurethane coating is led boots, and the technical matters that will regularly refuel.
But no matter be that above-mentioned self-lubricating nylon guide roller free of refueling or the metal guide boots that are coated with polyurethane outward all cannot be used in Fire lift system, because Fire lift system is mostly to use in presence of fire situation, therefore require the operation that each parts of elevator device can be stable under high-temperature, nylon guide boots in above-mentioned and the polyurethane external coating of metal guide boots be easily deliquescing or thawing in high-temperature situation, the guide function of boots itself is led in impact, when lift car is slided up and down in hoistway, easily produce and rock, serious may cause life safety misadventure.
Summary of the invention
The object of the invention is provides a kind of high strength that has in order to solve above-mentioned the deficiencies in the prior art, and the lift car that can use continually and steadily under hot environment is led boots.
To achieve these goals, the designed lift car of the present invention is led boots, comprises metal guide boots body, is coated with a teflon layer on the inside face of above-mentioned metal guide boots body.
The chemistry polytetrafluoroethylene by name of above-mentioned middle teflon, is a kind of current material, and it has good heat-resisting and low temperature tolerance characteristics.Short time can be high temperature resistant to 300 ℃, generally between 240 ℃ ~ 260 ℃, can use continuously, has significant heat stability, and polytetrafluoroethylcoating coating films also has lower friction coefficient simultaneously.When load is slided, friction coefficient changes, but numerical value is only between 0.05-0.15.Therefore invent at this, it seldom being elaborated.
When the above-mentioned boots of leading when slide in car guide rail, in order to reduce area of contact between the two, reduce friction drag between the two, on the inside face of described metal guide boots body, offer groove, above-mentioned groove is symmetrically arranged on the sidewall of metal guide boots body, and teflon layer covers groove surfaces simultaneously.
The lift car that the present invention obtains is led boots, in its structure, leading boots body adopts metal material to guarantee its intensity, in use be subject to be difficult for deformation and fracture under External Force Acting, on the inside face of above-mentioned metal guide boots body, be coated with a teflon layer simultaneously, make it outward when car guide rail slides up and down, both can not produce larger noise because of friction, and because teflon layer can be continuous between 240 ℃ ~ 260 ℃, stable use, therefore in fire, having adopted lift car provided by the invention to lead the Fire lift compartment system of boots still can be steady, the operation of safety.

Fig. 1 is the structural representation that embodiment 1 lift car that provides is led boots;
Fig. 2 is the sectional schematic diagram at a-a place in Fig. 1;
Fig. 3 is the structural representation that embodiment 2 lift car that provides is led boots;
Fig. 4 is the sectional schematic diagram at b-b place in Fig. 3.
In figure: metal guide boots body 1, sidewall 1-1, inside face 1-2, groove 1-3, teflon layer 2.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment 1:
As depicted in figs. 1 and 2, the lift car that the present embodiment provides is led boots, comprises that cross section is U-shaped metal guide boots body 1, it is characterized in that being coated with a teflon layer 2 on the inside face 1-2 of above-mentioned metal guide boots body 1.
Embodiment 2:
As shown in Figure 3 and Figure 4, the lift car that the present embodiment provides is led boots, its structure is consistent with embodiment 1 substantially, but when the above-mentioned boots of leading when slide in car guide rail, in order to reduce area of contact between the two, reduce friction drag between the two, on the inside face 1-2 of described metal guide boots body 1, offer groove 1-3 in the present embodiment, above-mentioned groove 1-3 is symmetrically arranged on the sidewall 1-1 of metal guide boots body 1, and teflon layer 2 covers groove 1-3 surface simultaneously.
Claims (2)
1. lift car is led boots, comprises metal guide boots body (1), it is characterized in that being coated with a teflon layer (2) on the inside face (1-2) of above-mentioned metal guide boots body (1).
2. lift car according to claim 1 is led boots, it is characterized in that offering groove (1-3) on the inside face (1-2) of described metal guide boots body (1), above-mentioned groove (1-3) is symmetrically arranged upper at the sidewall (1-1) of metal guide boots body (1), and teflon layer (2) covers groove (1-3) surface simultaneously.
