[0001] The utility model relates to the technical field of gantry frames, in particular to a mechanically processed gantry frame. Background Art
[0002] The gantry is a new type of small lifting gantry developed to meet the daily production needs of small and medium-sized factories (companies) for handling equipment, warehouse loading and unloading, lifting and repairing heavy equipment, and material transportation. It is suitable for mold manufacturing, auto repair factories, mines, civil construction sites, and other places where lifting is required. It is commonly used in construction to transport materials and move construction personnel up and down, realizing the mechanization of lifting. It can reduce manpower, reduce production and operation costs, and improve work efficiency.
[0003] When processing mechanical parts, since some mechanical parts are large in size and heavy in volume, a gantry is needed for lifting to facilitate subsequent processing operations. When the gantry is lifting the mechanical parts, it often uses hooks and other methods to lift them, which can easily cause the mechanical parts to swing and even cause the risk of falling.

[0010] Preferably, the force-applying structure includes mounting plates fixed to both sides of the top of the gantry body, a hydraulic rod penetrating through the top of the mounting plates, and a folding plate fixed to the output end of the hydraulic rod.
[0011] Preferably, a slide groove is provided on the outer surface of the gantry body, a slide plate is fixed to the side of the rack plate close to the gantry body, and the surface of the slide plate is movably connected to the inside of the slide groove.
[0012] Preferably, the length distance between the left and right sides of the inner side of the gantry body is longer than the length distance after the two support plates rotate to be parallel.
[0013] Preferably, a cushion is provided on the surface of one end of the support plate, and the cushion is made of rubber.
[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0015] The utility model has an arrangement in which the surfaces on both sides of the gantry body are rotatably connected to the support plates. After the mechanical accessories are hoisted, the force-applying structure can be used to apply force to the rack plate to push it, which can drive the gear and the support plate to rotate, so that the support plate can support the bottom of the mechanical accessories. This not only prevents the mechanical accessories from swinging when the gantry body moves, but also avoids the risk of the mechanical accessories falling. At the same time, through the arrangement of the fixed structure, the bottom of the gantry can be supported quickly and conveniently, thereby effectively improving the stability of the gantry when in use and avoiding shaking or even side sliding.
