Embodiment Construction

[0012] Below in conjunction with the accompanying drawings, the specific implementation and the essential features of the present invention will be further described. like Figure 1-3 As shown, the embodiment of the present invention is a step front beam, which can be molded and bent by a steel plate with a thickness of 1.8mm. The lower plate surfaces at both ends of the beam body in the horizontal direction are horizontal installation positioning surfaces 2, and the inner concave strip-shaped reinforcing ribs 3 are punched out on the lower plate surface of the beam body 1, and the front frame of the pedal assembly is opened on the plate surface of the beam body 1 The screw connection relief hole 11 and the front frame connection screw hole 12 of the pedal assembly, and weld nut holes 10 are opened at symmetrical positions at both ends of the beam body 1 in the length direction, and the welding nut 9 is inserted into the positioning welding from the lower plate surface for the...

Abstract

The invention relates to a front end cross beam of a stainless steel staircase step, in particular to a front end cross beam of a split assembled step, and belongs to the field of escalator manufacture. The lower part of a lath shaped beam body is provided with a first support reinforcing surface vertical to the beam body and a second support reinforcing surface parallel to the beam body respectively; and the cross sectional shape of the cross beam is a semi-closed shape surrounded by the lath shaped beam body, the first support reinforcing surface and the second support reinforcing surface, and each surface is formed by continuously bending. The invention solves the technical problem and provides the technical task that the front end cross beam overcomes the defects that the front end cross beam structure of the prior stainless steel staircase step has poor bending resistance and torsional property and has no or indefinite assembly standard, and provides the front end cross beam with definite anti-deforming aim, rigidity and strength meeting standard code requirements, and definite assembly and positioning standards.

Description

technical field [0001] The invention relates to a stainless steel escalator step front end crossbeam, in particular to a split assembly type step front end crossbeam. It belongs to the field of escalator manufacturing. Background technique [0002] Stainless steel escalator steps are a split-assembled structure, which has been widely produced and used for its light weight, economy, fine production, humanization and stable performance. Its structure mainly includes a tripod bracket assembly, and a pedal assembly, a kick plate assembly, a main wheel axle seat and an auxiliary wheel seat etc. which are fastened and connected to it with a number of screws. When working, the steps bear the gravity load acting on the tread surface and the traction load parallel to the guide rail of the ladder at the same time. In order to ensure the stability of the structural geometric dimensions of the steps under stress and the bending and torsion resistance of the pedal assembly under the ma...
