Description

Technical Field

[0001] The utility model relates to a fixing fixture for punching holes in elevator guide rails. Background Art

[0002] The elevator guide rail is an important component in the elevator system. It is mainly used to support the elevator car and counterweight and guide them to move vertically along a specific track. The guide rail is usually made of high-strength steel to ensure sufficient rigidity and durability. The elevator guide rail mainly supports, guides, and absorbs vibrations during elevator operation. The elevator guide rails on the market are divided into different types according to the design and purpose of the elevator. Common ones include T-type guide rails, U-type guide rails, etc. During the installation and maintenance of the elevator, the precise processing and installation of the guide rails are crucial. The drilling, fixing, and calibration of the guide rails require high-precision tools and methods to ensure the safety and performance of the elevator.

[0003] The drilling process of elevator guide rails mainly relies on manual operation or mechanical equipment. However, manual drilling is difficult to ensure the high-precision requirements of the drilling position, size and angle, which may lead to inaccurate docking when the guide rails are installed, affecting the stability and safety of the overall structure. When using mechanical equipment to drill holes, usually only one guide rail can be clamped for drilling. Most manufacturers use multiple devices to operate simultaneously to meet supply needs, resulting in higher production costs. Utility Model Content
