Abstract

A kind of tower crane standard knot cat ladder, including oblique cat ladder, also including otic placode(3), platform otic placode(9)With Xiao's axle(4).The oblique cat ladder is 77 ~ 80 with the angle α of horizontal plane;Two inclined ladder handrail of the oblique cat ladder(5)Upper end pass through connecting bolt(6)The bottom hole of two pieces of otic placodes of connection;The interstitial hole of two pieces of otic placodes is separately mounted on the angle steel of standard knot by Xiao's axle;Two inclined ladder handrail of the oblique cat ladder(5)Lower end be bolt-connected to two pieces of platform otic placodes(9)One end, the other end of two pieces of platform otic placodes is weldingly fixed on platform(8)On.This utility model tower crane standard knot cat ladder adopts human oriented design, and cat ladder is more laborsaving;Often save standard knot and be designed with platform, eliminate potential safety hazard.

Description

A kind of tower crane standard knot cat ladder
Technical field
This utility model is related to a kind of tower crane standard knot cat ladder, belongs to hoisting machinery technical field.
Background technology
Vertical type, i.e. standard knot cat ladder and platform are adopted traditional tower crane standard knot cat ladder into 90 more.This standard knot is climbed Ladder climbing gets up more hard, and when tower crane is higher, upper and lower tower crane personnel are often felt very tried by this cat ladder;And this The standard knot of cat ladder is planted, many producers just arrange a half space, therefore cat ladder people up and down to follow the line of least resistance, typically per 3 sections Member sufficiently cannot rest, and be that climbing tower leaves potential safety hazard.
The content of the invention
The purpose of this utility model is that, according to the problems that traditional tower crane standard knot cat ladder is present, this utility model is carried Go out a kind of tower crane standard knot cat ladder, using tiltedly climbing formula cat ladder so that get up laborsaving, people does not allow to be also easy to produce tired out.
The technical solution of the utility model is that a kind of cat ladder, is tiltedly climbed according to ergonomicss and practice using formula is tiltedly climbed Angle [alpha] is scheduled between 77 ° ~ 80 °, and this angle is got up than relatively labor-saving, and people does not allow to be also easy to produce tired out.This cat ladder also must simultaneously Platform must be set on every section standard knot, form tiltedly be climbed using this, staff has to pass through platform up and down, so as to fundamentally Prevent personnel's climbing tower phenomenon lack of standardization,
A kind of tower crane standard knot cat ladder includes oblique cat ladder, otic placode, platform otic placode and Xiao's axle.Two inclined ladder handrail of the oblique cat ladder Upper end by connecting bolt connect two pieces of otic placodes bottom hole;The interstitial hole of two pieces of otic placodes is separately mounted to standard by Xiao's axle On the angle steel of section;Tiltedly the lower end of two inclined ladder handrail of cat ladder is bolt-connected to one end of two pieces of platform otic placodes, two pieces of platform ears The other end of plate is weldingly fixed on platform;Tiltedly cat ladder and the angle of horizontal plane are 77 ~ 80.
This utility model has following some advantage than traditional method:
1st, this utility model tower crane standard knot cat ladder adopts human oriented design, and cat ladder is more laborsaving.
2nd, often save standard knot and be designed with platform, eliminate potential safety hazard.
3rd, 4 platform otic placodes are welded with traditional standard section and this oblique cat ladder can be just installed, repacking is convenient.
A kind of tower crane standard knot cat ladder of this utility model is applied to all kinds of lifting tower cranes.

In figure, 1 is standard knot;2 is oblique cat ladder;3 is otic placode;4 is Xiao's axle;5 is inclined ladder handrail;6 is connecting bolt;7 are Guardrail;8 is platform;9 is platform otic placode;31 is interstitial hole;32 is bottom hole.
Specific embodiment
Specific embodiment of the present utility model is as shown in Figure 1.
A kind of tower crane standard knot cat ladder of the present embodiment includes oblique cat ladder 2, otic placode 3, platform otic placode 9 and Xiao's axle 4.It is described tiltedly to climb The upper end of terraced two inclined ladder handrails 5 connects the bottom hole 32 of two pieces of otic placodes 3 by connecting bolt 6;The interstitial hole 31 of two pieces of otic placodes 3 leads to Cross Xiao's axle to be separately mounted on the angle steel of standard knot 1;Tiltedly the lower end of two inclined ladder handrail 5 of cat ladder is bolt-connected to two pieces of platforms One end of otic placode 9, the other end of two pieces of platform otic placodes 9 are weldingly fixed on platform 8;Tiltedly cat ladder 2 and the angle α of horizontal plane are 77 º~80º。
