Method for opening doors on four sides of observation elevator without machine room and observation elevator with opening doors on four sides

Abstract

The invention discloses a method for opening doors on the four sides of an observation elevator without a machine room and an observation elevator with the opening doors on the four sides. According to the method, two stand columns are installed on one pair of opposite corners of a well, a machine placing beam is installed on the upper portion of the well and used for bearing the total weight of the elevator, the pair of opposite corners of a lift car are installed on the inner sides of the stand columns through guide rails, the top of the lift car is connected with a counter-weight assembly through car roof wheels, wherein the counter-weight assembly is fixed to the outer sides of the stand columns, and the counter-weight assembly is connected with a traction machine installed on the machine placing beam. In this way, the lift car is opened on the four sides. The space of the well is sufficiently utilized, the large space of the lift car is guaranteed, people feel comfortable when taking the elevator, and construction cost can also be lowered.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a four-sided door-opening method for a machine-room-less sightseeing elevator and a four-sided door-opening sightseeing elevator. Background technique [0002] Traditional elevators generally have a single door with a common structure or a front-to-back through door, and some use a 90° right-angle door with a diagonal car frame design, and three-sided doors with a backpack frame structure. For large-sized shafts or high-rise buildings with special requirements, it is necessary to set doors in four directions, so as to achieve the purpose of quickly entering and exiting the elevator. At present, there are also four-sided door elevators, but due to the traditional structural design, the space utilization rate is low, the space requirements on the top floor are high, and it can only be used in the form of a machine room, which makes the application very limited.
