The invention discloses continuous drilling equipment for installation racks for forklift truck attachments. A plurality of conveying rollers are vertically arranged on a base and located in the same vertical plane. A first support roller set and a second support roller set are arranged on the two sides of the conveying rollers respectively. A machining rotary disk is located above the conveying rollers. During machining, the installation racks to be machined which are on the first support roller set and the second support roller set respectively are fed synchronously through rotation of the conveying rollers, and the corresponding positions of the two installation racks to be machined are machined synchronously through cutters on the machining rotary disk, so that the synchronism of feeding and machining is achieved, and the machining efficiency and machining precision are greatly improved. The continuous drilling equipment for the installation racks for the forklift truck attachments is simple in structure and reasonable in design. The two installation racks can be drilled synchronously, and the installation racks are machined automatically, so that the machining efficiency and machining precision are greatly improved, and energy consumption is reduced.
