Bottom net replacing equipment for crane

Abstract

The invention relates to the technical field of crane maintenance, and discloses a bottom net replacing equipment for a crane. The bottom net replacing equipment comprises a box body, long grooves are formed in the left side and the right side of the lower surface of the box body, two round rods are fixedly connected in each long groove, rollers are movably connected to the outer side walls of the round rods, a supporting plate is fixedly connected in the box body, motors are fixedly connected to the left side and the right side of the box body, and the output ends of the motors extend into the box body. A worker can place a bottom net in two frames in a sliding manner, pushing-in is flexible, the two frames are arranged on the left side and the right side, the supporting stability is high, the bottom net placed into the frames operates through micro push rods, electromagnetic plates are attracted to the bottom net, and the bottom net is pressed; by operating a rotating handle, abutting blocks on the side face can move in the horizontal direction, the bottom net can be pressed from the side face, and the bottom net in the frames can be prevented from shifting; and in addition, bottom nets of different sizes can be placed in the frames, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of crane maintenance, in particular to a bottom net changing device for a crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Also known as crane, aerial crane, crane. Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. [0003] Cranes are often seen in the construction industry. When the crane replaces the bottom net, the traditional device is inconvenient to operate. What angle is the object placed on the device? When the device is raised, the object will maintain the original angle or posture. However In actual use requirements, sometimes it is neces...

Problems solved by technology

[0003] Cranes are often seen in the construction industry. When the crane replaces the bottom net, the traditional device is inconvenient to operate. What angle is the object placed on the device? When the device is raised, the object will maintain the original angle or posture. However In actual use requirements, sometimes it is necessary to adjust the angle of the lifting object. At this time, the traditional method is to manually operate, and because the size of the object (bottom net) is different, the traditional device is more troublesome when lifting different objects, and it is not convenient to quickly For lifting and lowering objects of different sizes, a kind of bottom net changing equipment for cranes needs to be improved
