Description
Technical Field
The invention relates to an elevator guide rail fixing device.
Background
In the prior art, in order to ensure a smooth movement of the elevator car or the elevator counterweight in the elevator shaft, it is customary to mount on the wall of the elevator shaft vertically extending elevator guide rails which cooperate with shoes on the elevator car or the elevator counterweight so that a smooth movement of the elevator car or the elevator counterweight in the elevator shaft is ensured.
In the prior art, a guide rail bracket is fixed to a hoistway wall, and a guide rail pressing plate is fixed to the guide rail bracket and presses both sides of an elevator guide rail, thereby fixing the elevator guide rail to the guide rail bracket.
In the prior art, there are two kinds of guide rail pressing plates, one is a guide rail pressing plate for non-seismic working conditions, and the other is a guide rail pressing plate for seismic working conditions. Because the force borne by the guide rail bracket is greatly higher than the force borne under the non-earthquake working condition under the earthquake working condition, the mechanical strength of the guide rail pressing plate used under the earthquake working condition is far higher than that of the guide rail pressing plate used under the non-earthquake working condition. In the prior art, in order to improve the mechanical strength of a rail clamp for earthquake working conditions, thicker materials and more excellent steel materials are required. Thus, rail clamps for seismic conditions are typically thicker and heavier than rail clamps for non-seismic conditions, and the two are not interoperable, which reduces the versatility of the rail clamps.
In addition, in the prior art, since the rail pressing plate for the earthquake work condition is very thick and heavy, the vertical force caused by the building settlement is increased, and the design of the rail system is more complicated.
