The electric hoist of climbing frame is widely applicable to the safety requirements of high safety requirements such as metallurgy and explosion protection, and it is necessary to install safety brakes. The electric hoist of the climbing frame has a compact structure, and the electric hoist whose motor axis is perpendicular to the axis of the drum adopts a worm gear transmission device. The shortcomings of climbing frame electric hoist are: large length, large width, coarse structure, low mechanical efficiency, and difficult processing. The hydraulic system is dual-controlled, and the overflow regulating valve and magnetic contact pressure gauge can accurately control the pressure. The electrical control department uses low voltage control to increase the safety of the control system. When the braking torque of the cone-shaped brake motor disappears or the transmission link breaks to cause acceleration of the load, the safety brake will serve as an emergency braking protection. The ratchet and pawl device is the most important way of climbing the electric hoist safety brake. The overspeed rotation of the drum will trigger the ratchet and the ratchet to engage to produce a braking mode. When the load drops at a stable lifting speed, the reel rotates in a counterclockwise direction, and the guide rail drives the swing arm to perform periodic shaking. When the roller is disengaged from the guide rail, the tension spring gradually expands due to inertia, the spring force gradually increases, and the swing arm is reset to the initial state, and enters the next shaking cycle. The spring effect causes the pawl to undulate and lack ratchet engagement. When the load accelerates down, the roller accelerates and shakes, and the swing angle gradually increases until the pawls engage the ratchets, and the ratchets press the friction plate to generate frictional resistance to complete the deceleration stop. When the pawl is engaged, the roller swings clockwise outward, driving the lower lever to trigger the electrical switch, opening the control ring in the downward direction, and the cone brake brakes quickly. When the lift button is pressed, due to the tension of the spring, the pawl will actively disengage from the ratchet, and then the electric switch is reset, thereby triggering the ratchet by acceleration. Electric hoist group crane Electric hoist is generally installed on single beam crane, bridge crane, gantry crane, hanging crane. With a little modification, it can also be used as a winch. Therefore, it is an essential machine for improving labor efficiency and working conditions. It is widely used, but there are few professionals who can correctly operate the group hoist electric hoist. It is recommended that you know more about the group hoist electric hoist, so as to make better use of the group hoist electric hoist in various fields. Creating a world brand and making fine products is our unswerving goal. .
