Abstract
The utility model relates to a sectional and assembling type step of an escalator, which is formed by that a left and a right triangular frames which are in punching form with steel sheets are taken as supporting members, and the triangular frames which are respectively and independently assembled with sectional structures are connected with a pedal component, a front cross beam, a main wheel shaft seat, a kick plate component and an auxiliary wheel shaft seat, etc. Each component is assembled to be assembled finally to be a final product, and thus quality depends on moulds without the need of mechanical processing and correcting work; the utility model has the advantages of simple punching process, low rejection rate, high dimensional precision, good consistency, can take material with high rigidity, can endure operation with heavy load in long time; an individual part can be individually replaced when damaged, overcoming the defect of integral rejection, and thus the utility model has low maintenance cost and convenience.
Description
The utility model relates to the escalator step structure.
Step is the chief component of escalator, is the lorry of the special structure form of standing for the passenger.The main wheel wheel shaft of each step and conduction chain kink together, all steps move on guide rail.In a staircase, step is the maximum movable parts of quantity, so the performance of escalator and quality quality depend on the performance and the quality of step to a great extent.The escalator step of China's production at present adopts the aluminum alloy integral die-cast, this kind step productive costs is higher, complex process, difficulty of processing is big, press casting procedure is prone to quality problems such as SOL or tissue looseness, so mechanical strength is lower, material is crisp and light, be in operation and can empathize, vibration is big, must be at the bonding noise reduction glue of pedal inwall, also owing to reasons such as environmental conditions, human element, parts itself, phenomenons such as the pedal tooth fractures, the kickplate face crashes can take place, and partial failure will change whole step, and is extremely uneconomical." the two-in-one assembly unit step of escalator " disclosed technology of the patent No. 96200971.7 is to be connected on the left and right spider by screw by the pedal of aluminium alloy compression casting, kickplate, strengthen Joint strenght by reinforcement, this step still exists complex process, difficulty of processing is big, the local tooth that easily produces fractures, the kickplate face crashes, the aluminum alloy die casting periphery will carry out machine up, kickplate needs the mould tire pressure to proofread and correct before the assembling, interchangeability is poor, and the step after the assembling need enter boring processing or the like the defective that bore hole carries out main wheel axis hole and jockey pulley axis hole.
The purpose of this utility model all provide in the defective that overcomes prior art a kind of and homemade staircase supporting, each assembly independently assemble laggard capable general assembly need not process, proofread and correct the assembled escalator step of product, its technology is simple, with low cost, reject rate is low, the step good rigidly, easy to maintenance, even step has partial failure, as long as change local part, needn't change whole step.
By above-mentioned purpose, embodiment of the present utility model is: escalator step is a supporting member with left and right spider, its top is provided with the pedal assembly that periphery has demarcation, the place ahead is provided with the main wheel axle bed that is connecting the sliding nail of guiding, the rear is provided with the kickplate assembly, the back lower place is provided with the jockey pulley axle bed, it is characterized in that described spider, pedal assembly, main wheel axle bed, kickplate assembly, jockey pulley axle bed are independent stack-mounted split-type structural separately, and is provided with front cross rail in spider the place ahead.
The utility model is owing to adopt independent separately stack-mounted split-type structural, each assembly is assembled laggard capable general assembly and is final products, quality depends on mould and do not need machine up need not proofread and correct, and Sheet Metal Forming Technology is simple, and reject rate is low, the dimensional accuracy height, high conformity can adopt the material of good rigidly, can bear long-time, heavy service, individual part damages and only needs indivedual the replacing, and service expenditure is low and convenient.
