Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

The elevator car guide rail bracket as shown in fig. 1 and 2 mainly comprises a cross angle iron assembly 1 and two groups of vertical angle iron assemblies 2 which are matched with each other.

The transverse angle iron assembly 1 comprises transverse angle iron 11 and two guide rail pressure plate groups 12 which are arranged on the transverse angle iron 11 at intervals; the cross angle iron 11 takes a conventional shape, and specifically, includes a first straight plate 111 and a second straight plate 112 formed at either side of the first straight plate 111 and perpendicular thereto, such that the cross section of the cross angle iron 11 has a 90 ° right angle. Each guide rail pressing plate group 12 comprises two guide rail pressing plates 121 which are arranged at intervals in a matched mode, and the guide rails are limited and arranged on the transverse angle iron 11 through the two guide rail pressing plates 121; the rail pressing plate 121 is installed in the following manner: is mounted on the second straight plate 112 by a first pair of bolts 122. When in use, two groups of transverse angle iron assemblies 1 which are arranged at intervals and in parallel are generally adopted to mount and support the guide rail.

There are two sets of the angle iron assemblies 2, which are respectively installed at both ends of the first straight plate 111. Each set of vertical angle iron assembly 2 comprises vertical angle iron 21 mounted at the end of the first straight plate 111 (the vertical angle iron 21 also adopts the conventional shape), two hollow guide rail pressing plates 22 which are mounted on the vertical angle iron 21 through a second bolt pair 23 and are matched with each other, bottom angle iron 25 mounted at the free end of the vertical angle iron 21 and parallel to the transverse angle iron 11 (the bottom angle iron 25 also adopts the conventional shape), and a plurality of expansion screws 24 mounted on the bottom angle iron 25 and used for fixing to the wall of the hoistway (in this way, the bottom angle iron 25 is mounted on the wall of the hoistway by the plurality of expansion screws 24 to realize the support of the whole elevator car guide rail bracket).

The transverse angle iron 11, the vertical angle iron 21 and the bottom angle iron 25 are made of S500MC or QSTE500TM materials independently, the tensile strength is 520-750 MPa, the yield strength is 550-720 MPa, the elongation is 16%, the thickness of the steel plate can be 3.8-4.2 mm, and the steel plate is preferably 4mm; at the moment, the manufacturing process of parts such as the transverse angle iron 11, the vertical angle iron 21, the bottom angle iron 25 and the like is not changed from the original manufacturing process, but after the S500MC or QSTE500TM material is adopted, the weight of the elevator car guide rail bracket is reduced by about 30 percent compared with the weight of the elevator car guide rail bracket manufactured by the original common angle iron, and the manufacturing cost is reduced by about 20 percent; the bearing strength of the elevator guide rail bracket finally made of high-strength alloy steel can be improved by about 12%.
