Abstract

The invention discloses a multifunctional pipe hoisting machine. The multifunctional pipe hoisting machine comprises a rotation base, a mobile counterweight device, an engine, a pipe carrying device, a driving cab, a cargo boom, a lifting hook, an excavating device and a walking device, wherein an oil cylinder moving left and right is mounted on the rotation base; one end of the oil cylinder moving left and right is stretched out of the rotation base and fixed on a support frame; the support frame is mounted on the rotation base; the support frame slides on the rotation base; a counterweight is fixed on the support frame; a turning oil cylinder tank is formed in the counterweight; a turning oil cylinder is mounted in the turning oil cylinder tank; the lower end of the turning oil cylinder is hinged with the support frame; the upper end of the turning oil cylinder is hinged with the counterweight; the counterweight rotates around a rotation shaft on the counterweight under driving of the turning oil cylinder. The multifunctional pipe hoisting machine has three functions of hoisting, excavating and carrying pipes; the mobile counterweight device is used in cooperation with the multifunctional pipe hoisting machine for realizing two actions; the counterweight is capable of moving left and right and turning backwards, so that the stability of the engine can be improved; the weight of the counterweight is reduced under the conditions with same load; the multifunctional pipe hoisting machine is simple in structure and convenient to manufacture and maintain.

Description

technical field [0001] The invention relates to a crane, in particular to a multifunctional pipe layer with functions of digging and pipe backing. Background technique [0002] With the rapid development of large-scale industries in our country, the laying volume of pipe network projects is increasing. Pipeline transportation, lifting and engineering excavation are all completed by different construction machinery, resulting in the disadvantages of large equipment investment, high labor intensity, low construction efficiency, long construction period and high construction cost, but if the lifting, excavation and back pipe They are all concentrated on the same crane. Since a lot of loads are added to the counterweight crane, the weight of the counterweight must be designed according to its maximum load. There is a large margin in normal operations, and the whole machine is heavy, and it will also Increase the economic cost such as fuel consumption during operation. Content...
