The Method of Improving the Comprehensive Performance of the Miscellaneous Ladder

Abstract

The invention discloses a method for improving the comprehensive performance of a dumbwaiter lift. The two sides of guide rails are connected with a car guide shoe and a counterweight guide shoe respectively, so that a car and a counterweight share the guide rails, and the overall occupied area is reduced. Stand columns and cross beams are connected through kidney-shaped holes in the stand columns, every two stand columns are spliced through a stand column connecting piece, and a shaft frame can be mounted and adjusted conveniently. A landing door is opened and closed conveniently through a landing door handle device. The dumbwaiter lift constructed according to the method comprises the shaft frame (1), and the car (2) is arranged in the shaft frame (1). The car (2) is connected with the guide rails (4) through the car guide shoe (3), and the guide rails (4) are connected with the counterweight (6) through the counterweight guide shoe (5). The landing door (7) is arranged on the shaft frame (1), and the landing door handle device (8) is arranged on the landing door (7). The overall occupied area can be reduced, the car can be expanded, the construction efficiency of the shaft frame can be improved, and the advantages that the precision of the shaft frame is easy to adjust, and the landing door is convenient to open and close are achieved.

Description

technical field [0001] The invention relates to a method for improving the performance of the debris ladder and the debris ladder, in particular to a method for improving the comprehensive performance of the debris ladder and the debris ladder. Background technique [0002] At present, in order to maximize the usable area of ​​the entire building in most places such as libraries and high-end hotels, the area occupied by the wells of the debris elevators reserved is very small, resulting in the installation of the debris elevators. The ladder is inconvenient to use. The construction of the derrick used in the existing debris ladder is generally welded with profiles, and large-scale lifting equipment is required when building the derrick. The construction efficiency is low and it is difficult to adjust the precision of the derrick after the construction is completed. Moreover, the landing doors of the sundries ladder are generally opened and closed manually, and there is a ce...

Problems solved by technology

[0002] At present, in order to maximize the usable area of ​​the entire building in most libraries and high-end hotels, the reserved space for the wells of the debris elevators is very small, resulting in the installation of the debris elevators. The ladder is inconvenient to use

The derrick used in the existing debris ladder is generally welded with profiles, and large lifting equipment is required when building the derrick, the construction efficiency is low and it is difficult to adjust the precision of the derrick after the construction is completed

Moreover, the landing doors of the debris ladder are generally opened and closed manually, and there is a certain inconvenience in the opening and closing operation.

Therefore, the existing debris ladder has the problems of large overall floor area, small car, low derrick construction efficiency, difficult adjustment of derrick precision and inconvenient opening and closing of landing doors.
