Remotely-controllable crawler crane

Abstract

The invention discloses a remotely-controllable crawler crane. The remotely-controllable crawler crane comprises a vehicle body, wherein a crawler belt is arranged at the lower end of the vehicle body, a movable arm is rotationally connected to the front end of the vehicle body through a rotating shaft, a hook is arranged at the tail end of the movable arm, and a mounting box is fixedly connected to the lower end of the vehicle body. An adjusting mechanism used for adjusting the gravity center of the crane is arranged in the mounting box, the adjusting mechanism comprises an electromagnetic plate fixedly connected to the inner wall of the mounting box, and the electromagnetic plate is elastically connected with a permanent magnet block through a plurality of supporting springs. A rotating rod is rotationally connected to the inner wall of the mounting box, the rotating rod is in transmission connection with the rotating shaft through a belt, and a electrically conductive plate is fixedly connected to the side wall of the rotating rod. Two fixing plates are fixedly connected to the inner wall of the mounting box. The gravity center of the crawler crane can be dynamically adjusted, the gravity center of the crane can be kept in the middle regardless of the magnitude of the rotating angle of the movable arm and the mass of the lifted goods, and the crawler crane is prevented from inclining forwards and tipping over.

Description

technical field [0001] The invention relates to the technical field of crawler cranes, in particular to a crawler crane that can be remotely controlled. Background technique [0002] Crawler crane is a kind of self-propelled crane for high-rise building construction. It is also a kind of boom rotating crane that uses crawlers to walk. The crawler has a large ground area, good passability, strong adaptability, and can walk with a load. Hoisting operations can also carry out various operations such as digging, ramming, piling, etc. In the current construction industry, a series of crawler cranes that can be remotely controlled have also been designed, that is, there is no need for the driver to control the crane in the car to perform a series of operations , the crane can be controlled through external signal transmission. [0003] And existing crane is when working, in order to prevent itself from toppling over, generally only works on the flat ground, can not work in the ar...

Problems solved by technology

[0003] And existing crane is when working, in order to prevent itself from toppling over, generally only works on the flat ground, can not work in the area with some higher slopes again, but, when crane picks up goods, the rotation of boom also can make The center of gravity of the crane shifts, and the existing way to prevent the shift of the crane's center of gravity is to add counterweights. The position of the counterweights is fixed, but the working state of the boom is dynamic. It is impossible to ensure that the center of gravity of the crane remains in the middle of the fuselage at all times. In addition, when lifting goods, the overall center of gravity of the crane is also different due to the weight of the goods. Therefore, it is necessary to design a crawler crane that can be remotely controlled to solve the above problems. question
