Abstract

The utility model provides a solid lead rail for an elevator, comprising a bottom part, a neck part and a guide surface; the lead rail has the width of 82mm, the height of 62mm, the guide surface width of 15.88mm, the guide surface height of 30mm, the connecting width between the bottom part and the guide surface of 8mm, the bottom surface root part thickness of 10mm and the cross section bottom surface end part thickness of 7.5mm. According to the stress characteristics of all parts of the lead rail in the operating process of the elevator, the systematized optimization is carried out, so that the shape of the cross section of the lead rail is improved, and the shape of the connecting inclined surface between the neck part and the bottom part can be improved; therefore, a triangular supporting system formed between the guide surface and the two ends of the bottom part is more reasonable, and the stress of all the parts of the lead rail of the elevator can be better in accordance with the safety of operation of the lead rail. Meanwhile, on the premise of ensuring the safety of the operation of elevator, the material consumption of the lead rail is reduced, the product cost is greatly reduced, and a great deal of steel can be saved, so that great economic benefit and social benefit can be generated.

Description

The solid guide rail of elevator

Technical field

The utility model relates to the solid guide rail of a kind of elevator, relates in particular to the solid guide rail of a kind of T type elevator.

Background technology

At present, along with expanding economy, high level in the city reaches more, and skyscraper gets more and more, the application of elevator more and more widely, therefore the demand to cage guide also increases day by day, but GB/T22562-T89/B commonly used is applied in that not only safe effect is undesirable on the elevator, and consumptive material is more, thereby has influenced the field of application of cage guide.

Summary of the invention

The purpose of this utility model provides the solid guide rail of a kind of elevator, with safety, traveling comfort and the reduction cost of product that guarantees elevator.For this reason, the utility model is by the following technical solutions: it comprises bottom, neck and spigot surface, the guide rail width that it is characterized in that it is 82mm, rail height is 62mm, guide rail spigot surface width is 15.88mm, and guide rail spigot surface height is 30mm, and guide rail bottom is 8mm with the width that is connected between the spigot surface, the thickness of guide rail bottom surface root is 10mm, and the thickness of track cross-section bottom end is 7.5mm.

Described guide rail is provided with the guide rail tenon along an end of its length direction, and the other end is provided with the guide rail tongue-and-groove that matches with the guide rail tenon.

The tolerance of described guide rail width is ± 1.5mm, the tolerance of described rail height is ± 0.75mm, the tolerance of described guide rail spigot surface width is+0.1mm that the tolerance of described guide rail spigot surface height is ± 3.0mm that the tolerance of the thickness of described track cross-section bottom end is ± 0.75mm.

The beneficial effects of the utility model are: guide rail width of the present utility model is little than GB/T 22562-T89/B, the utility model is according to the loading characteristic at guide rail each position in running process of elevator, carried out systematized optimization, not only improved the shape of track cross-section, also improved the shape that connects the inclined-plane between neck and the bottom, make that the gusseted system that forms between spigot surface and the two ends, bottom is more reasonable, make the stressed safety that meets the guide rail operation more in each position of cage guide, simultaneously under the prerequisite that guarantees lift running safety, the consumptive material of guide rail reduces, greatly reduce cost of product, great deal of steel be can save, thereby huge economic benefit and social benefit produced.The utility model can replace the T89/B guide rail, is used in load-carrying 1000Kg, on the elevator of car deadweight 1500Kg.

The specific embodiment

With reference to accompanying drawing 1-4.The utility model comprises bottom 1, neck 2 and spigot surface 3, and its guide rail width b1 is 82mm, and rail height h1 is 62mm, and guide rail spigot surface width k is 15.88mm, and guide rail spigot surface height n is 30mm, and the guide rail bottom is 8mm with the width c that is connected between the spigot surface.The deviation of the guide rail width b1 of described guide rail is ± 1.5mm.

The thickness f of described guide rail bottom surface root is neck and flex point place, the bottom horizon vertical distance to the bottom, as shown in Figure 1, the thickness f of guide rail bottom surface root is 10mm, between described neck and the bottom for being connected smoothly, the thickness g of track cross-section bottom end is the minimum thickness of bottom, and the thickness g of track cross-section bottom end is 7.5mm.

The utility model meets elevator operation standard GB7588-2003, it is better than T75/B performance to have, and than the lightweight characteristics of T89/B, the utility model can reach the effect of GB/T 22562-T89/B, can be applicable to load-carrying 1000Kg, on the elevator of car deadweight 1500Kg.

The utility model not only has and reduces metal consumption, cost-cutting, advantage such as easy for installation, but also can save great deal of steel, steel wherein per ton can be produced 72.5 meters GB/T 22562-T89/B, after adopting the technical solution of the utility model, can produce 78 meters GB/T 22562-T82-3/B,, save 5 yuan for every meter and calculate according to the consumption in 1 year of solid guide rail T89/B, 70 myriametres, can save 3,500,000 yuan in 1 year, and this shows that the utility model can produce huge economic benefit and social benefit.

Described guide rail is provided with guide rail tenon 4 along an end of its length direction, and the other end is provided with the guide rail tongue-and-groove 5 that matches with the guide rail tenon.Butt joint between the guide rail tenon 4 of guide rail and the guide rail tongue-and-groove 5 of adjacent rails realizes the location thereby make between the adjacent rails, guide rail is remained on the same rectilinear orbit.

Described guide rail bottom is respectively equipped with 2 spot-facings 6 in the spigot surface both sides, between the adjacent rails except that realizing being connected by guide rail tenon and guide rail tongue-and-groove, also utilize connecting panel 7 to connect, described connecting panel 7 is provided with the through hole 8 that matches with spot-facing 6, described connecting panel is placed the guide rail bottom surface, and described through hole 8 and spot-facing 6 realize that by mechanical connection manners commonly used such as bolts the firm of adjacent rails is connected.
