Abstract
The utility model discloses a novel combined return rail of a staircase, comprising a return rail main body. The novel combined return rail of a staircase is characterized in that a main wheel working surface and an auxiliary wheel working surface are arranged on the return rail main body, and the main wheel working surface and the auxiliary wheel working surface are parallel to each other. Because the working surfaces arranged on two return rail main bodies are combined on one return rail main body, and requirements on the parallelisms of the two working surfaces are guaranteed according to the utility model, so that a guarantee on the stable running of the staircase can be achieved, thus increasing the installation efficiency of workers, and decreasing the costs of installation, maintenance and raw materials.
Description
Technical field
The utility model relates to a kind of escalator, and rail is returned in particularly a kind of novel staircase combination.
Background technology
In the prior art; Staircase returns rail and is generally main wheel and returns rail and return two guide rails that separate of rail with jockey pulley; During installation, its main wheel returns two driving surfaces that rail and jockey pulley return rail needs manual work critically to regulate its parallelism, wastes time and energy; Take bigger installation and maintenance cost, the guide rail cost of raw material is also higher simultaneously.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of novel staircase to return rail, in the time of with assurance staircase smooth running, installs to reduce, and safeguards the cost of raw material.
The utility model solves the technical scheme that its technical matters adopted:
Rail is returned in a kind of novel staircase combination, comprises and returns the rail main body, and it is characterized in that: the said rail main body of returning is provided with main wheel driving surface and jockey pulley driving surface, and main wheel driving surface and jockey pulley driving surface are parallel to each other.
The beneficial effect of the utility model is: be combined to one and return on the rail main body because the utility model returns the driving surface that is provided with on the rail main body with two; And guaranteed the parallelism requirement of two driving surfaces; Guarantee the staircase smooth running thereby can reach, not only improved workman's installation effectiveness but also reduced installation, maintenance and the cost of raw material.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the schematic cross-section of the utility model;
Fig. 2 is the application scheme drawing of the utility model.
The specific embodiment
With reference to Fig. 1, the utility model discloses a kind of novel staircase combination and return rail, comprise and return rail main body 1; Return rail main body 1 and be provided with main wheel driving surface 2 and jockey pulley driving surface 3, and main wheel driving surface 2 and jockey pulley driving surface 3 be parallel to each other, in this specific embodiment; Return whole section bar of rail employing and process the main wheel driving surface 2 and jockey pulley driving surface 3 that is parallel to each other respectively; Not only need material few but also when rail is returned in installation, do not need the parallelism of manual shift main wheel driving surface 2 and jockey pulley driving surface 3, saved manpower, thereby also reduced installation; Safeguard the cost of raw material.
As shown in Figure 2, Fig. 2 is the application scheme drawing of the utility model, originally returns the general paired use of rail, and main wheel driving surface 2 is positioned at the below of jockey pulley driving surface 3, and step main wheel 4 is installed on the main wheel driving surface 2; Step jockey pulley 5 is installed on the jockey pulley driving surface 3, and said structure has been guaranteed the parallelism requirement of jockey pulley driving surface 3 and 2 liang of driving surfaces of main wheel driving surface, promptly guarantees the smooth running of step main wheel and step jockey pulley.
Above-mentionedly just some preferred embodiments of the utility model are illustrated and describe; But the embodiment of the utility model is not restricted to the described embodiments; As long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection domain of the utility model.
