Abstract

The utility model, a principal bearing module for a construction elevator, refers to a head grideway stand of the construction elevator, composing up-and-down connecting main string tubes, angle steel and joint bolts. The model features that one end of the main string tube is welted with an upper plug and the other hereof with a lower plug. Advantages of the utility model include: anti-rust on the inner wall of the main string tube which controls thickness reduction of the tube wall thereof and extends its service life, and rigidity enhancement which strengthens stability during installation and security during operation.

Description

The end socket guide rail bracket of building construction hoist

Technical field

The utility model relates to a kind of end socket guide rail bracket of building construction hoist, is the main load-supporting part of building hoist, belongs to building hoist guide rail bracket technical field.

Background technology

Guide rail bracket is the main load-supporting part of building hoist, can increasing and increase gradually with building, it is again the guide rail that terraced cage moves up and down, bearing the various loads in the building hoist ladder cage up-and-down movement, the main chord tube of the guide rail bracket that uses is the solid drawn pipe of Φ 89 or Φ 76 at present, and direct barrel type connects form.Owing to revealing spacious operation usually, long construction period, environment is abominable, the oxidation corrosion of guide rail bracket is serious, particularly the corrosion of guide rail bracket main chord tube inwall can't be struck shovel and paint, generally finishes an engineering, returns a maintenance and just can find that a large amount of sheet corrosion pieces peel off, directly influence the wall thickness of main chord tube, reduced guide rail bracket weight capacity and service life.In addition because the guide rail bracket quality is heavier, the main chord tube wall is thin, add that the workyard environment is poor, in the mounting or dismounting transportation, phenomenons such as the main chord tube two ends of guide rail bracket Zhuan Deflated often takes place, come off, distortion, bring difficulty to trimming, have a strong impact on installation quality and service life, and bring serious hidden danger to safety in production.

Summary of the invention

The purpose of this utility model is a kind of main chord tube inwall non-corrosive of invention, the end socket guide rail bracket of the building construction hoist that increases the service life.

For realizing above purpose, the technical solution of the utility model provides a kind of end socket guide rail bracket of building construction hoist, and it is made up of lower link, angle steel, attachment bolt on the main chord tube, and its characteristics are, end at main chord tube is equipped with lower end cap, is equipped with upper plug head at the other end of main chord tube.

The utility model has the advantages that:

1. the plug of burn-oning at the main chord tube two ends seals main chord tube, all can not infiltrate in the pipe no matter rain, snow, in addition, airborne etchant gas also can't enter in the pipe, effectively prevent the corrosion in the pipe, under equal usage condition, will prolong 2-3 service life doubly, and controlled the unpredictalbe tube wall thickness that causes by corrosion spalling of main chord tube tube wall, improved the reliability of safety in production.

2. the plug of burn-oning at the main chord tube two ends, area of contact corresponding increase in termination helped steadiness and interchangeability in the installation process when guide rail bracket connected.

3. the plug of burn-oning at the main chord tube two ends made thiner originally steel pipe partial change over entity, had increased rigidity, and damage or the distortion that can effectively resist various bump and produced have guaranteed installation quality and service precision, had also saved cooperage usefulness simultaneously.

Description of drawings

Fig. 1 is the end socket guide rail bracket structural representation of building construction hoist;

Fig. 2 is that the end socket guide rail bracket of building construction hoist connects section-drawing.

The specific embodiment

As shown in Figure 1, 2, be the end socket guide rail bracket structural representation of building construction hoist, it is made up of lower link, angle steel 2, attachment bolt 3, lower end cap 4, upper plug head 5 on the main chord tube 1.

Select close casting lower end cap 4 of 20# aluminium and upper plug head 5 for use, the diameter of its diameter and main chord tube 1 is complementary, and lower end cap 4 is the convex plectane, and upper plug head 5 is the spill plectane, and the convex of its spill and lower end cap 4 is complementary.At an end of main chord tube 1 lower end cap 4 of burn-oning, the other end upper plug head 5 of burn-oning, again the main chord tube 1 that welds is linked up with angle steel 2 and attachment bolt 3 up and down, like this main chord tube 1 on correct the lower end that connects next root main chord tube 1, lower end cap 4 coincide with upper plug head 5, has avoided the corrosion of moisture content and air.

Claims

1. the end socket guide rail bracket of a building construction hoist, upward lower link, angle steel (2), attachment bolt (3) are formed by main chord tube (1) for it, it is characterized in that, be equipped with lower end cap (4), be equipped with upper plug head (5) at the other end of main chord tube (1) at an end of main chord tube (1).
