摘要:
Method and system for installing the guide rails (1, 2), such as the car guide rails and/or counterweight guide rails, in an elevator shaft (3). The guide rails are installed by assembly in phases starting from the bottom (4) of the elevator shaft by placing one on top of the other guide rail sections (51, 52; 61, 62; 71, 72 . . . ) that are shorter than the whole length of the guide rail and by aligning the guide rail sections perpendicularly by means of the laser beam produced by a direction laser (8). The direction laser (8) is moved upwards along with progressive assembly of the guide rail. As assembly progresses the direction laser (8) is supported in the proximity of the top end of the topmost vertically aligned guide rail section at the time for aligning the next guide rail section to be installed in the vertical direction. These phases are repeated until the entire guide rail is assembled. The system comprises an alignment appliance (12), which can be supported against a guide rail section and fixed to it by means of a permanent magnet (20). In addition the alignment appliance contains an aligning element (13), at which the laser beam produced by the direction laser can be directed.

A multiple function cross-head for an elevator is horizontally disposed at the upper ends of two vertical stiles that form an elevator car frame. The cross-head supports a door header, door hanger assembly, door operator assembly, and a cross-beam. The cross-beam supports a sheave assembly which engages a rope in an elevator system to raise and lower the elevator car in a shaftway.

An improved method for mounting elevator rails within a hoistway includes the initial step of securing support brackets to a pair of rails. The brackets, rails, a machine for driving a cab and a dead end hitch are then mounted within the hoistway. A cab may then be moved vertically within the hoistway and additional support brackets are placed at vertically spaced locations. The connection of the brackets and rails provides support to dissipate the loads which are transferred into the rail in such systems wherein the machine or the dead end hitch is fixed to a rail. Once the rails have been adequately supported by additional brackets, the brackets which are secured to the rails are removed from the rail. The brackets provide support, but are no longer fixed to the rails.

The invention relates to a procedure and an apparatus intended to be used in elevator installation to install the overspeed governor (28) for the time it takes to install the elevator. According to the invention, when the elevator is being installed, at least one suspension element (17) is fastened to the upper part of the elevator shaft (2), an element (30) supporting the overspeed governor (28) is fitted to the suspension element and the position of the overspeed governor (28) at least in the vertical direction is so adjusted that it corresponds to the final placement of the overspeed governor (28). After the elevator guide rails (56) have been installed, the overspeed governor is removed from the suspension element (17) and fixed to a guide rail.

An apparatus and method for installing car and counterweight rails for elevators accurately positioned the rails in a linear, parallel orientation. The apparatus includes a pair of mirror-image guide assemblies which attach to the rails. Each assembly includes an adjustable reference guide assembly which positions the rail relative to an adjacent plumb line. The assembly also includes an interconnecting guide line which ensures co-planar disposition of certain rail surfaces. The method includes the steps of suspending the car and counterweight rails within the elevator shaft from above. A plumb line is suspended adjacent each rail. The lower terminus of each rails is then secured in an appropriate position relative to the other rails and the hoistway walls. The guide assemblies are then secured to the rails and adjusted to receive the plumb line in a reference location. The assemblies are then incrementally moved up the rails, the rails are adjusted such that the plumb line is received within the assemblies at the reference location and the rails are secured to the shaft walls in the desired position.

An arrangement and method for installing guide rails of an elevator. The arrangement comprises an installation platform movable vertically in an elevator shaft and one or more guide rail baskets hanging below a floor of the installation platform for carrying guide rail elements vertically. The several guide rail elements are transported in one transport drive from a lower loading level to a higher installation level by means of the arrangement. This way, several successive sections of the guide rails can be installed at the installation level.

The invention relates to an elevator arrangement, comprising a hoistway one or more vertically oriented guide rail lines in the hoistway for guiding vertical movement of one or more movable elevator units, and one or more movable elevator units mounted in the hoistway vertically movably along one or more guide rail lines, including at least an elevator car, preferably also a counterweight, and a hoisting roping; a movable support structure mounted in the hoistway for supporting said one or more movable elevator units below it via said hoisting roping, and a hoisting machine on the movable support structure for moving the hoisting roping, for thereby moving said one or more movable elevator units. Said movable support structure comprises a body portion, and a shelf structure projecting laterally from the body portion, and the hoisting machine is mounted on the shelf structure. The invention also relates to a method for constructing an elevator implementing the arrangement.

An elevator system (2) comprising a hoistway (4), an elevator car (6) and a counterweight (8) arranged to move within the hoistway (4). The system (2) further includes a first counterweight guide rail and a second counterweight guide rail arranged to guide the counterweight within the hoistway (4) and a guide rail bracket (32) which connects the first and second counterweight guide rails together. An elevator machine (10) is arranged to drive a tension member (14), which couples the elevator car (6) and counterweight together (8), to move the elevator car (6) within the hoistway (4). The system (2) further includes a friction reducing element (36) arranged on the guide rail bracket (32) such that if the tension member (14) moves towards the guide rail bracket (32) during operation of the elevator system (2), the tension member (14) contacts the friction reducing element (36).

Disclosed embodiments provide techniques and apparatus for installing an elevator. A support frame is assembled at the top of an elevator passage. The permanent elevator motor is installed in the support frame. The permanent motor is then used to hoist materials as needed to build out the elevator system. Once built, the permanent motor that is already installed and has had hours of usage to verify its operation, is used for movement of the elevator car for the completed elevator system.
