Description

Technical Field

[0001] This utility model relates to the technical field of gantry adjustment and correction devices, specifically a horizontal measuring fixture for gantry installation and adjustment. Background Technology

[0002] A gantry crane is a structural system in mechanical equipment, typically composed of columns, beams, a worktable, and slides. Due to its stable structure and open working space, it is widely used in the machining industry. Gantry cranes are suitable for various cutting, milling, drilling, and engraving processes, and can process large workpieces or special materials. For example, in the machine tool industry, large gantry milling machines are often used to process large castings, steel, and heavy machine parts. Additionally, gantry cranes are widely used in ports, bridges, and building materials industries for lifting and moving heavy objects.

[0003] However, the leveling adjustment of large gantry mill bed installations often relies on manual judgment and experience, resulting in a high error rate. This is especially true for moving column gantry mills or gantry mills that are too wide, where visual inspection makes it difficult to guarantee installation quality and ensure that the left and right beds are parallel after installation. Although a fixture can be assembled and fixed onto the slide block after the bed is installed, and a level measuring instrument can be placed on the fixture, the mounting base of this fixture is often made of cast iron, which is heavy, and the measuring support is made of welded steel, whose rigidity does not meet the requirements. Therefore, it is necessary to propose a level measuring fixture for gantry mill installation and adjustment to overcome the above problems. Utility Model Content
