Description

Method Of Installing Elevator Cable and Guide Rail
Background of the Present Invention
The present invention relates to elevator construction, and more particularly to a method of installing elevator cable and guide rail by means of a rail guiding carrier, which facilities the elevator construction process and reduces the constructing labor and cost.
An elevator arrangement comprises a car which is hanged by a predetermined number of elevator cables and guided by die guide rails to move up and down within an elevator passage provided in a building. There are usually four guide rails for each elevator, in which two of the four guide rails are incorporated with the car for guiding the up and down transportation of the car, and the other two guide rails are adapted for guiding the movement of the counterweight. Each guide rail is constructed by a plurality of rail units connected end to end.
As shown in Figs. 1 and 2, each rail unit A is about 5 meters long, having a T-shaped cross section (as shown in Fig. 1). Each rail unit A comprises a head portion Al, a neck portion A2, and a base portion A3, wherein the base portion A3 is an elongated metal plate. The neck portion A2 is extended perpendicularly from a central portion of the base portion A3 and along the length of the base portion A3. The head portion A 1 is an enlarged head extended from a free end side of the neck portion A2, so that the head portion Al has a larger thickness than the neck portion A2. A predetermined number of fastening holes A4 are provide at the two ends of die base portion A3 respectively.
The most common way to install the guide rails in the elevator passage is to rigidly affixed a predetermined number of supporters B to the wall of the elevator passage in equally spaced apart manner for locking the plurality of rail units thereto (as shown in Fig. 2). A bridge element C is screwed to the two opposing ends of two rail units A of the guide rail through the fastening holes A4 diereon so as to firmly connect the plurality of rail units A longitudinally together to construct the continuous guide rail on the wall of the elevator passage.
In accordance with the conventional construction of the guide rails as described above, the procedure of installing the guide rails in a high rise building includes die following steps. Firstly, lift all the rail units A to die top floor. Secondly, lower all the rail units A by cable from the top floor down to the bottom of the elevator passage. Thirdly, build a scaffold inside the elevator. Fourthly, install the rail units A one above another upwardly manually by the construction workers. The scaffold is built inside die elevator passage for supporting the construction workers. The construction workers on the scaffold have to manually pass the rail units A up one by one and firmly secured each rail unit A on the respective supporters. In order to install the guide rail from the base floor to the top floor inside of the elevator passage of a high rise building (more than 30 meters tall), at least 6 construction workers are needed. As the height of the building increases, the number of the construction worker needed would increase proportionally. Usually, for every 5 more meters of the height of e building, an additional construction worker would be required. For a 30-floor building, more than 20 construction workers are needed to install the guide rails.
People might doubt ώat why not the constructors just simply install the units from me top floor by lowering one rail unit after another and lock to the supporters respectively in order to eliminate the extra step of lowering all the rail units A to the bottom of the elevator passage. In this way, we can conserve the construction time and some construction workers for passing up the rail units A. The reason is that each rail unit A has a common length (5 meters) and a sustain among of weight constructed out of steel alloy (its weight are 15 kg/m or above). Therefore, if the rail unit A is lowered directly from the top floor, it would start to spin along the way. Moreover, the rail unit A may hit the scaffold or the supporter, and dius cause damage or deformation to the rail unit, scaffold, and/or supporter. The most critical thing is that if care is not implemented during construction, the construction workers would be strike by the lowering rail unit A and be serious injured and diat such mistake can never be recover.
Normally, the cables utilized in die elevator arrangement can mainly divide into diree category: (1) hoist cables which are connected to the car and die counterweight; (2) compensator cables which are connected to die bottom of me car and die counterweight; (3) safety cables which are connected to die brake device. All the cables described above are installed at a final stage of die elevator construction. The installation of each cable needs to start from the top floor of die elevator passage. Each cable should be lowering from the top floor and passing dirough a pulley or a pulley assembly back and forth. Accordingly, another transporting cable must be fastened to an end portion of the cable which is lowered to the bottom of the elevator passage, in order to lead and pull the end portion of the cable from the bottom floor back to the top floor and pass dirough the pulley or the pulley assembly again.
Due to the reason that die cable was collect in a circuling manner, and dius the cable would spin as it is lowering to the bottom of the elevator passage. The spinning cable may hit against the wall of the elevator passage and die guide rails, or even get stuck on the supporters diat support the guide rails. The construction workers would not know the cable got stuck on the supporter immediately. Once me construction workers find out that the cable is stuck, die cable would have to be pulled up and repeat the lowering process from beginning. The present method to solve diis problem is to add a weight at the end of die cable but die result is not desirable. When the lowering cable reaches a certain height, the spinning action of die cable would occurs once again. Summary of the Present Invention
The main objective of me present invention is to provide a method of installing elevator cable and guide rail by means of a rail guiding carrier, which facilities die elevator construction process and reduces die constructing labor and cost.
It is another objective of the present invention to provide a method of installing elevator cable and guide rail by means of a rail guiding carrier, which can prevent die lowering cable from spinning, hitting e wall of the elevator passage, scaffold or guide rails, and getting stuck with the supporters.
