The present invention relates to the technical field of elevator guide rail processing, in particular to a tool for detecting the hole position of the elevator guide rail, comprising: a detection rod body, a cylindrical rod body, a conical head and a cylindrical base, and a first countersunk pass through the end of the cylindrical rod body. The air hole, the second countersunk air hole with the same diameter as the first countersunk air hole is provided on the cylindrical base, and the first channel connecting the inside and outside of the first countersunk air hole is provided on the cylindrical rod body, and the communication hole is provided on the cylindrical base. The second countersunk head passes through the second passage inside and outside the air hole; the installation seat is provided with installation grooves for accommodating the cylindrical base one by one, and the bottom periphery of the groove body of the installation groove is evenly distributed with ventilation holes, and the cylindrical base is fitted with the installation groove. , also includes a sealing cover body, the sealing sleeve is arranged on the periphery of the cylindrical rod body, and seals the open end of the installation groove. In the present invention, through the use of the above detection tool, it can be quickly determined whether the shape and position tolerances between the fixing holes on the elevator guide rail meet the requirements.
Description
technical field [0001] The invention relates to the technical field of elevator guide rail processing, in particular to an elevator guide rail hole position detection tool. Background technique [0002] The elevator guide rail is an elevator component composed of steel rails and connecting plates. It is divided into car guide rails and counterweight guide rails. The cross-sectional shape is mainly T-shaped. The impact force and the impact force of the safety gear during emergency braking, etc. [0003] Both ends of the elevator guide rail are provided with a number of fixing holes for fixing. Since the elevator guide rail is a key component that affects the operation and safety of the elevator, the detection accuracy of the hole diameter and hole distance of the fixing holes is particularly important. At present, vernier calipers are used to detect one by one. This detection method has relatively low work efficiency and is prone to errors. [0004] In view of the existence...
