Detailed Description

The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

The utility model discloses an elevator auxiliary rail system through addding supplementary spacing subassembly, provides extra position restraint when the car operation has the swing, has improved car operation quality.

As shown in fig. 1, the utility model discloses an elevator auxiliary rail system, including derrick 1, car 2, guide rail set spare 3 and supplementary spacing subassembly 4, car 2 is located derrick 1, and car 2 goes up and down under guide rail set spare 3's guide effect, supplementary spacing subassembly 4 is used for cooperating with guide rail set spare 3, leads and spacing to car 2 at car 2 lift in-process, guarantees car 2 even running.

Specifically, a hoistway 11 is formed in the derrick 1, and the car 2 is located in the hoistway 11. The car 2 comprises a front side 21, a rear side 22, a left side 23 and a right side 24, wherein the front side 21 is opposite to the rear side 22, the left side 23 and the right side 24 are opposite, and the left side 23 and the right side 24 are adjacent to both the front side 21 and the rear side 22. In this embodiment, a pair of guide rail assemblies 3 are provided on the rear side of the car 2, and the car 2 is vertically movable with respect to the car 2 by the guide action of the pair of guide rail assemblies 3. This embodiment does not restrict the concrete structure of guide rail set spare 3, as long as can provide the guide structure of guide effect for car 2 all is applicable to the utility model discloses.

The car 2 is except that in other three sides of its rear side, namely left side 23, right side 24 and front side 21, at least one side sets up supplementary spacing subassembly 4, and supplementary spacing subassembly 4 is used for cooperating guide rail set 3 to carry on spacingly to car 2 in car 2 lift process, avoids car 2 to take place the swing phenomenon.

In this embodiment, the auxiliary limit component 4 is disposed on the right side of the car 2, and of course, in other embodiments, the auxiliary limit component 4 is disposed on the left side of the car 2, or a set of auxiliary limit components 4 is disposed on both the left side 23 and the right side 22 of the car 2, or the auxiliary limit components 4 are disposed on both the left side 23, the right side 24, and the front side 21 of the car 2.
