Elevator guideway fixed device

Abstract

The objective of this invention is to provide a fixed installation of elevator guide rails where welding job is reduced to the minimum, while sufficiently ensuring position adjustment tolerance of the guide rails, and assuring miniaturization at the same time. In the solution of this invention, a first face 11a and a second face 12a of a wall-side metallic part 1a are each formed with a first slant slot 111a and a second symmetrical, slant slot 112a, respectively; a first face 11b and a second face 12b of a rail-side metallic part 1b are each formed with a third slot 121b opposing and normal to the first slot 111a and a fourth slot 122b opposing and normal to the second slot 112a, respectively. The width dimensions of the opposing paired slots are provided to provide sufficient position adjustment tolerance of the guide rails.

Description

technical field [0001] The invention relates to a fixing device for a guide rail of an elevator. The guide rail for guiding the operation of the passenger box and the balance weight of the elevator is fixed on the wall of the elevator road. Background technique [0002] Generally speaking, the guide rail that is erected in the hoistway of the elevator and guides the lifting body is composed of a rail side fitting that installs the guide rail and a wall side fitting that fixes the rail side fitting to the hoistway wall. The fixing device is fixed on the lifting road wall. [0003] In addition, the guide rail side fittings and the wall side fittings are formed into a slightly L shape by the horizontal plane and the vertical plane, respectively, on the horizontal plane, connecting the linear direction of a pair of guide rails, that is, a vertically long hole is provided in the horizontal direction, and , in the vertical direction of the wall side fittings, the direction st...

Problems solved by technology

[0007] However, on the above-mentioned conventional guide rail fixing device, the inconvenience is that the adjustment range in the horizontal direction is insufficient, and the guide rail needs to be displaced to an appropriate position for adjustment, which is very difficult.

That is, on the general fixing device, since the longitudinal holes are set on the two horizontal planes of the wall side fittings and the guide rail side fittings, the adjustment range of the two longitudinal holes will be provided. Longitudinal holes on the horizontal plane of the side fittings ensure the adjustment range in the horizontal direction, so the adjustment range is only about half, which makes it difficult to adjust the guide rail to the proper position

[0008] In addition, on the horizontal plane where the wall side fittings and guide rail side fittings are bumped and closed, each longitudinal long hole and horizontal long hole are combined to implement position adjustment. Interference between the horizontal long hole and the guide rail clamp hole used to install the guide rail clamp, so the shape of the guide rail side fittings needs to be enlarged, so the lifting space must be enlarged, so it is difficult to achieve the reduction of welding work and space efficiency duality
