Abstract

An elevator guide rail installation bracket and installation method thereof, a positioning tooling, a bracket adjustment tooling, and an elevator system. The elevator guide rail installation bracket includes a guide rail bracket having a guide rail installation surface and a first adjustment surface that form a bend, a fixed guide rail installation position is provided on the guide rail installation surface; and a hoistway bracket having a hoistway installation surface and a second adjustment surface that form a bend; the first adjustment surface is adjustably connected to the second adjustment surface to adjust the relative position between the guide rail installation surface and the hoistway installation surface.

First claim

What is claimed is:

1. A positioning tooling for an elevator car, comprising:
a fixing mechanism detachably fixed to an elevator car in a construction hoistway;
a telescopic mechanism connected to the fixing mechanism and configured to extend to or retract from the wall surface of the construction hoistway; and
a positioning mechanism provided at the end of the telescopic mechanism that abuts against the wall surface of the construction hoistway along with the extending motion of the telescopic mechanism;
wherein the telescopic mechanism includes:
a base connected to the fixing mechanism and provided with a threaded through hole; and
a telescopic screw screwed to the threaded through hole of the base, with its end provided with the positioning mechanism;
wherein, the rotating motion of the telescopic screw relative to the base is converted into an extending motion or a retracting motion of the telescopic screw to or from the wall surface of the construction hoistway;
wherein the base is pivotally connected to the fixing mechanism by a hinge, and is configured to rotate relative to the fixing mechanism between a position facing the wall surface of the construction hoistway and a position deviating from the wall surface of the construction hoistway.

2. The positioning tooling according to claim 1 , wherein the fixing mechanism comprises a clamping bracket for clamping and being detachably fixed to a top guardrail of the elevator car in the construction hoistway.

3. The positioning tooling according to claim 1 , wherein the positioning mechanism comprises a wall surface support seat, and wherein the first side of the wall surface support seat is provided with a gasket, the second side of the wall surface support seat is arranged at the end of the telescopic mechanism, and the gasket abuts against the wall surface of the construction hoistway along with the extending motion of the telescopic mechanism.
