A remote control crawler crane

Abstract

The invention discloses a crawler crane capable of remote control, which comprises a body, the lower end of the body is provided with crawlers, the front end of the body is rotatably connected to a boom through a rotating shaft, the end of the boom is provided with a hook, and the lower end of the body is An installation box is fixedly connected; the installation box is provided with an adjustment mechanism for adjusting the center of gravity of the crane, and the adjustment mechanism includes an electromagnetic plate fixedly connected to the inner wall of the installation box, and the electromagnetic plate is elastically connected with a permanent magnet through a plurality of support springs block; the inner wall of the installation box is rotatably connected with a rotating rod, and the rotating rod is connected to the rotating shaft through a belt, and the side wall of the rotating rod is fixedly connected with a conductive plate; the inner wall of the installation box is fixedly connected with two fixed plates. The present invention can dynamically adjust the center of gravity of the crane, so that the center of gravity of the crane can be maintained in the middle regardless of the rotation angle of the boom and the quality of the goods lifted, preventing the crane from tipping forward.

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
