Elevator assembled by utilizing combination type derrick

Abstract

The invention discloses an elevator assembled by utilizing combination type derricks, relating to hoisting equipment. A hoistway wall of the elevator is formed by assembling more than two derricks, wherein each derrick comprises stand columns, a door beam, a front beam, a back beam, a left beam, a right beam, a cage guide rail and a counter-weight guide rail, wherein the four stand columns are distributed at four corners of the derrick, and connection seats are horizontally and fixedly arranged at the top end and the bottom end of each stand column and provided with connection holes; two ends of the door beam, the front beam, the back beam, the left beam and the right beam are transversely and respectively connected with the stand columns; and the cage guide rail and the counter-weight guide rail are respectively installed in the middle parts and the inner sides of the back ends of the left beam and the right beam. Because the derricks can be produced in a standardized way in a factory and assembled on site, the working time limit can be shortened, the cost can be lowered, the manufacturing cost can be reduced, and the installation efficiency and quality can be improved; and because the derricks are matched with an up-down door-opening and closing mechanism, the influence of the installed elevator on ventilation and daylighting of a household can be reduced. The elevator assembled by utilizing the combination type derricks is mainly used for places of low storey dwelling houses, in particular to the old style low storey dwelling houses of less than 9 storeys.

Description

technical field [0001] The present invention relates to a hoisting device, in particular to an elevator. Background technique [0002] The hoistway is the running space of the elevator car. The hoistway is surrounded by the hoistway wall. The hoistway wall is used to install the guide rail and separate the wall or structure between the hoistway and other places. The structure can be a frame composed of civil engineering , It can also be a metal frame. The well wall of a modern elevator is generally a wall. There are guide rails on the wall of the hoistway, and guide shoes on the car. The car slides on the guide rails through the guide shoes to keep the car on the correct running route in the hoistway. [0003] Modern elevators are very mature in terms of traction technology and electronic group control technology, but if an elevator is installed in an old low-rise residential building, the shaft wall and door opening and closing mechanism of the existing elevator will be di...

AI Technical Summary

Problems solved by technology

The construction work of the shaft wall civil works is heavy, the construction period is long, and the cost is high. The cost of the civil works is close to the selling price of the elevator itself. If the installation fee is added, it often greatly exceeds the cost of the elevator itself.

[0006] At the same time, the installation quality of the elevator will seriously affect the safety performance and service life of the elevator.

The key to elevator installation is the installation of guide rails. The guide rails are installed on the well wall through guide rail brackets, and the well wall is civil engineering, so it is difficult to ensure the installation accuracy of the guide rails

[0007] 2. Modern elevators adopt left and right side door opening and closing mechanisms, which occupy a large horizontal space

Adding elevators to old low-rise residences, the closed shaft project itself affects the ventilation and lighting of the stairs, and modern elevators use left and right side door opening and closing mechanisms, and the door machine system of the elevator occupies a large horizontal space, so The installation of elevators greatly affected the ventilation and lighting of the stairs, so it was opposed by many low-rise residents
