The invention discloses a two-way driving safety control device. A guide frame of a sliding box of the device is fixed on a machine rack; a shell body of the sliding box and a bottom plate of the sliding box are connected to constitute a sliding box body, an inner sliding plate, two guide rods, a pair of springs and a main drive rod are arranged in the sliding box body, the pair of springs are respectively sheathed on the two guide rods, the inner sliding plate is arranged on the two guide rods and moved up and down on the two guide rods, the main drive rod is connected with the inner sliding plate; the sliding box body is respectively connected with a locking screw rod and a positioning hydraulic cylinder of the sliding box through pin shafts, the locking screw rod is locked on the guide frame of the sliding box through a pair of locking nuts, and the positioning hydraulic cylinder of the sliding box is fixed on the guide frame of the sliding box. The device adopts the springs with the pre-tension force as position limiting and return power, so the distance between a plate hammer and an impact plate can be automatically adjusted during the work, and the device can prevent materials from generating blockage and seizure during the work; the device has simple structure and reliable work, thereby being economical and easy in maintenance.
Description
technical field [0001] The invention belongs to the safety control technology, in particular to a bidirectional drive safety control device for the impact plate of an impact crusher. Background technique [0002] The impact crusher is an efficient crushing equipment in the crusher industry, and it is widely used in metallurgy, mining, building materials, chemicals, ceramics, road construction and other industries. It mainly uses the high-speed rotating hammer head to impact the material block. The impacted material obtains huge kinetic energy and rushes to the impact plate. After the impact of the impact plate, the material is crushed along its weak part. When the impact crusher is working, the material has to go through multiple strikes and counterattacks in the crushing cavity. It organically combines the crushing principles of strike, counterattack, centrifugal impact, and shearing, so that its energy can be fully and effectively utilized. High crushing efficiency, less ...
