Elevator center opening door head provided with multifunctional limiting plate structure

Abstract

The invention relates to an elevator center opening door head provided with a multifunctional limiting plate structure. The elevator center opening door head comprises a bottom plate, a left hanging plate, a right hanging plate and a latch hook mechanism, wherein a guide rail is arranged on the bottom plate along the length direction; the two ends of the upper part of the bottom plate are separately provided with a rope wheel; the left hanging plate and the right hanging plate are separately provided with a guide wheel; the left and right hanging plates are arranged in the guide rail in a guiding manner; the middle part of the bottom plate is provided with a fixing hook of the latch hook mechanism; an elastic hook of the latch hook mechanism is arranged on the left hanging plate; a counterweight rope wheel is arranged on the left hanging plate; a rubber post is arranged on the right hanging plate; the elevator center opening door head is characterized in that a limiting base is fixedly arranged on the middle part of the bottom plate; the limiting base is provided with a bottom assembly plate, a left side vertical plate and a right side vertical plate; the right side vertical plate of the limiting base corresponds to the rubber post in position; and a counterweight steel wire rope fixing end assembly hole is formed in the left side vertical plate. By adopting the elevator center opening door head, assembly space on the hanging plates can be effectively saved; the counterweight steel wire rope fixing base and the limiting plate are integrated through the limiting base, so that the technique is greatly simplified; certain working procedures are omitted; and production cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to an elevator center door head with a multifunctional limiting plate structure. Background technique [0002] The composition of the elevator fire door includes: fire landing door device, fire door panel, fire door cover, fire sill, etc.; its main door opening methods mainly include: middle split, side opening double fold, middle split double fold, etc., the most common one is the middle Fraction. In addition to the functions of ordinary doors, elevator fire doors also play a vital role in preventing floor fires from spreading through the elevator shaft. For the middle split fire door, the door head device is composed of a bottom plate with guide rails and two left and right hanging plates, and the left and right two door plates are respectively driven to move by the left and right hanging plates. The guide rail adopts the method of bending on the bottom plate to make the guide...
