Abstract
The utility model relates to an escalator principal machine base. The escalator principal machine base solves the problems that a common principal machine base is insufficient in tensile strength and poor in design applicability. The principal machine base comprises a base support which is formed by main beams arranged on two sides of a truss and two cross bars connected between the main beams. Two fixing plates connected with supporting feet of a principal machine are connected between the two cross bars. Kidney-shaped holes used for fixing the supporting feet of the principal machine are respectively arranged at two ends of the fixing plates. A pressing mechanism is arranged on the base support. The escalator principal machine base has the following advantages that positions of the principal machine on the transverse direction and the longitudinal direction can be adjusted, and installation efficiency is improved; the pressing mechanism is arranged and can press the principal machine from the front direction, the back direction, the left direction and the right direction, and installation strength of the principal machine is improved; connecting plates are arranged, the principal machine is fixed by vertical bolts and horizontal bolts instead of being fixed by the vertical bolts directly in the past, and pressure and tension applied on the bolts are reduced.
Description
Technical field
The utility model relates to a kind of escalator structure, relates in particular to a kind of different model main frame that adapts to and installs, fixes more fastening escalator main frame base.
Background technology
The power of staircase operation is from main frame.Therefore, main frame need be fixed on the truss by failure-free.In the ordinary course of things, four pin that connect main frame by bolt are fixed on two beams that are welded on the truss.On the one hand, the propulsive effort that produces from main frame can be sent to the main drive shaft assembly, thereby make whole escalator system operation, on the other hand, the braking force that produces of the additional brake braking that causes because of normal operation braking or emergency situation four pin that also should be fixed on the main frame on the truss girder are supported.
At present, most main frame is by being bolted on two beams that are welded in truss.Four under-chassis of main frame directly link to each other with truss main frame crossbeam, between without any any transition connecting devices such as interface boards.Use dissimilar main frames if desired, the staircase that is used for different configurations because of them has different three-dimensional structures or size, main frame base welded structure on truss just need be modified, and to adapt to the size of required main frame, this has just increased the complexity of truss structure design.In addition, the main frame body comprises that under-chassis generally all is cast structure, and casting can provide enough intensity and pressure resistance, but the opposing stretch capability is more weak.If the main frame leg is directly connected on the truss, connect by vertical bolt merely, bolt will bear pressure and pulling force repeatedly.Particularly the pulling force of the maximum that produces when emergency braking may destroy the bolt of four legs of whole main frame.Therefore, existing main frame base has the not enough and poor shortcoming of design applicability of tensile strength.Be 201110143253.0 as application number, name is called the Chinese patent application of the Host Security device of escalator or moving sidewalk, this patent comprises main frame and base, by attached Fig. 1 and 2 as can be seen, base is provided with mounting hole, the leg of main frame by bolt directly and mounting hole fix, just there is above-mentioned shortcoming in this: the main frame leg is directly connected on the truss, simple by vertical bolt connection, bolt will bear pressure and pulling force repeatedly.The pulling force of the maximum that produces when emergency braking may destroy the bolt of four legs of whole main frame.
Summary of the invention
