Problems solved by technology
[0003] The guide rail is transported from the hall door on the first floor to the top of the shaft, and it is very easy to touch the shaft wall and scaffolding in the narrow shaft, causing the guide rail to be bumped and damaged
After such a guide rail is installed, the installation accuracy cannot be guaranteed
If the elevator is less comfortable, if it is serious, the guide rail will be seriously damaged and replace the guide rail
May cause delays in the construction period, increase costs and other consequences

The invention discloses a guide rail pulling device for pulling up a to-be-installed guide rail along an installed guide rail. The to-be-pulled guide rail and the installed guide rail each comprise abottom and a guide part which are perpendicular to each other. Each guide part comprises two opposite side faces and a top face away from the bottom. The guide rail pulling device is characterized bycomprising a pulling plate which is fixed to the bottom of the to-be-pulled guide rail, and a side face wheel assembly and a top face wheel assembly which are arranged on the pulling plate, and the side face wheel assembly and the top face wheel assembly are fixed to the pulling plate through a connecting arm assembly. According to the guide rail pulling device, the side face wheel assembly slideson the side face of the guide part of the installed guide rail so as to drive the to-be-pulled guide rail to slide, and therefore a safe lifting route can be provided for the to-be-pulled guide railin the guide rail hoisting process, the guide rail is protected against collision damage in the pulling process, installing and detaching are convenient, and the guide rail pulling device can be usedmultiple times.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to a lifting device suitable for lifting guide rails of elevators. Background technique [0002] The installation accuracy of the guide rail is very important to the smooth operation of the elevator, especially for the elevator with a large lifting height and a fast running speed. Therefore, ensuring that the guide rails are not affected by external factors before installation is a prerequisite for ensuring the quality of elevator installation. [0003] The guide rail is transported from the hall door on the first floor to the top of the shaft, and it is very easy to touch the shaft wall and scaffolding in the narrow shaft, causing the guide rail to be bumped and damaged. After such a guide rail is installed, the installation accuracy cannot be guaranteed. In light cases, the comfort of the elevator is poor, and in severe cases, the guide rails are severely damaged and the guide...
