Description
Technical field
The present invention relates to a kind of escalator, a kind of specifically light-duty step of aluminum alloy integral die-cast.
Background technology
Escalator in the elevator industry is had many uses general in the public transport field; As: subway, high ferro, light rail, station, harbour, pedestrian overpass, market, supermarket, office building etc.; About demand 40,000 escalators in annual world market, every escalator on average disposes 100 aluminum alloy steps, about 4,000,000 of total demand; Calculate by each 1000mm type aluminum alloy step average quality 12.5kg, a year consumption aluminum alloy reaches 50,000 tons; Big (width 1002 ± the 0.5mm * the degree of depth 404 ± 0.5mm * height 303 ± 0.25mm) of step foundry goods; Step width dimensions long (1002 ± 0.5mm); The step wall thickness is thin (2.2+0.3mm); The tread tooth bar of step very carefully very close (facewidth 2.5mm * tooth depth 11mm, totally 110); Nearly 33 of the push rods of step; Step die casting total weight reaches 32 tons, because of inserts volume moving, cover half is bigger, causes the temperature of each inserts of mould different, and poor stability is difficult to control, so, often causing the die casting step to be shaped and be difficult to, reject rate is high.Present step weight lays particular stress on, and except that expending aluminium material resource, also directly influences workman's moving when the Installation and Debugging escalator, increases labour intensity; The total weight of step on staircase is bigger than normal, can cause the drive motor power consumption of whole escalator to increase simultaneously; The right-angle type physical construction easy fracture and the size of the spider profile that supports about step are thick partially; Step tread and riser wall thickness dimension are thick partially; The outward appearance physical construction of step tread yellow plastic frame is prone to explosion and the frame screw terminal is installed exposed; Step push rod quantity is the Design of Mechanical Structure defectiveness of 33 and push rod position nearly; Do not manufacture and design invention in the dynamic model of step die casting and the cover half inserts physical construction of fluid oil constant temperature circulation cooling channel system.
Summary of the invention
In order to address the above problem, the invention provides a kind of light-duty step of aluminum alloy integral die-cast of staircase, the aluminum alloy cost reduces, and saves bauxite resource, and staircase is light, has reduced labour intensity, saves energy, built-in screw terminal reduces potential safety hazard.
In order to address the above problem, the present invention realizes through following technical scheme:
The present invention is a kind of light-duty step of escalator aluminum alloy integral die-cast; Comprise the tread that constitutes step; Riser and about support the triangular support bracket of tread and riser; On the opposite of riser one main gusset is set, equalization is provided with 3 reinforced ribs between the inboard of riser and main gusset, and the outside of triangular support bracket also is provided with outer reinforced rib; The two ends of the two ends of said 3 reinforced ribs, each triangular support bracket and outside a push rod all is set on the outside of reinforced rib, also be provided with yellow caution frame in the outside of tread.
Further improvement of the present invention is: the profile of triangular support bracket is the channel-section steel type, and the thickness of triangular support bracket is 2.5+0.3mm.
Further improvement of the present invention is: the thickness of tread and riser is 1.8+0.2mm.
Further improvement of the present invention is: the inboard of tread is screwed installation through screw to frame.
Further improvement of the present invention is: the aluminum alloy step is that integral die-cast is shaped, and the dynamic model of die casting and dynamic model inserts are the physical constructions of fluid oil constant temperature circulation cooling channel system.
The invention has the beneficial effects as follows: tread, riser, the spider of aluminum alloy step reached through the moderate reduction wall thickness dimension alleviate step to 9.5Kg by former 12.5Kg; Realize that whole step reduces the purpose of 3Kg aluminum alloy; Both saved bauxite resource in short supply, reduced aluminium step material cost, alleviated to the Light Aluminum Alloy step of the yellow caution of the tread band PC plastic frame of 9.5Kg; Send national elevator quality supervision and test center to do type test; All can satisfy dynamic load, the static load of National standard GB16899-2011 and the standard EN 115-1:2008 of European Union, each item technology and the requirements for quality of torsion test, after the aluminum alloy step alleviated, the workman of Elevator Factory was when assembling and debugging escalator; Move briskly, reduced labour intensity; Simultaneously, the gross load of escalator configuration step is reduced, thereby make the drive motor power consumption gross horsepower of escalator reduce,, be reduced to 1.1kw/h, practiced thrift electric energy and use cost by original configuration power of motor 1.5kw/h.The spider that supports about the aluminum alloy step is set to the physical construction of " channel-section steel type "; The stress point of easy fracture and riser reverse and yieldingly are solved because of changing over " channel-section steel type " structure; And wall thickness dimension reduced; Both aluminium step overall weight was alleviated the stability that can improve the quality again; In being set to, the exposed holding screw head of the yellow caution of aluminum alloy step tread installation PC plastic frame screws; Promoted the taste of outward appearance; To be prone to cause the hidden danger of quality of PC plastic frame explosion to eliminate simultaneously, and guarantee the security and stability that escalator uses and save maintenance cost; Mould flow field simulation analysis of experiments through mould software; With 33 of aluminum alloy step push rod quantity and push rod structure position layout again; Be reduced to 11, causing the push rod structure position, rationally to get push rod quantity small but excellent, thereby reduced the cost that uses and keep in repair the step mould; Mould flow field simulation analysis of experiments through mould software; Manufacture and design invention in the dynamic model of step die casting and the cover half inserts physical construction of fluid oil constant temperature circulation cooling channel system; The Die Oil temperature control machine of configuration right quantity;, cover half inserts moving to mould set and applied different steady temperatures; Thereby solved die casting to the aluminum alloy integral cascade of die casting " foundry goods is roomy, long, wall book, tread tooth bar quantity many, radicula " be shaped difficult, qualification rate and all low hard nut to crack of output, step casting forming qualification rate brings up to 99% by former 93%; Current yield was brought up to 1000 by former 600 in 24 hours, and amplification reaches 40%.
The present invention is simple in structure, and is easy to make, and cost-cutting reduces labour intensity.
