Apparatus for acquiring specific ground pressure of crawler belt of crane and crane

Abstract

The invention discloses an apparatus for acquiring the specific ground pressure of the crawler belt of a crane and the crane and relates to the technical field of engineering machinery. The invention overcomes the technical problem that bearing capability of a foundation is difficult to match with the specific ground pressure of the crawler belt of a crane in the prior art. The apparatus for acquiring the specific ground pressure of the crawler belt of the crane comprises a moment limiter, an angle sensor, a controller and a display, wherein the moment limiter and the angle sensor are in electric connection through a line or in wireless connection through a wireless transmitter-receiver unit, the moment limiter is used for detecting the weight value of a heavy object born by a main arm of the crane and the amplitude value of the heavy object, the controller is used for establishing a plane rectangular coordinate system with the revolution center of the main arm as the origin of coordinates, and the angle sensor is used for detecting the value of an operating angle of the main arm of the crane. The crane comprises the apparatus for acquiring the specific ground pressure of the crawler belt of the crane. The apparatus and the crane provided by the invention are used for improving matching between bearing capability of a foundation and the specific ground pressure of the crawler belt of the crane.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a crane crawler belt grounding specific pressure acquisition device and a crane provided with the crane crawler belt grounding specific pressure acquisition device. Background technique [0002] A crawler crane (or crawler crane) is a crane with a lattice boom structure that uses a crawler chassis. [0003] At present, the working conditions of crawler cranes are generally harsh, especially the road conditions on which crawler cranes walk. The ground specific pressure of the track refers to the vertical load on the unit area of ​​the track. The average grounding specific pressure of general crawler cranes is very small, and there is usually no problem when walking on some bad roads without a load, but many working conditions need to travel with a load. At this time, the local grounding specific pressure of the crawler of the crane may be very large. It is very lik...

Problems solved by technology

[0005] Because the bearing capacity of the foundation in the prior art is difficult to match with the grounding pressure of the crane's crawler, there is no ideal benchmark for the degree of foundation treatment. If the foundation treatment is not in place, the poor bearing capacity of the foundation will still lead to the crane walking on the foundation. In case of danger, if the foundation is treated too well and the bearing capacity of the foundation is set too high, a lot of manpower and material resources will be wasted, which is uneconomical
