A kind of hydraulic plate floating crane

Abstract

The invention discloses a floatable crane with a hydraulic slab. The floatable crane with the hydraulic slab comprises two floating tanks and a plurality of hoisting devices; the two floating tanks are connected to form an 'H'-shaped operation platform by a connecting body; two ends of the floating tanks are symmetrically provided with a fixing seat; the fixing seat is provided with supporting devices for enabling the crane with the floatable hydraulic slab to be positioned on a field operation surface; the supporting devices are provided with hydraulic systems for driving the supporting devices to hoist; the hoisting devices are fixed on the floating tanks or the connecting body. The floatable crane with the hydraulic slab has the advantages that the two floating tanks are arranged and are connected to form the 'H'-shaped operation platform by the connecting body, so that the floatable crane has the high operation reliability and safety; the hydraulic systems are used for driving the supporting devices to hoist, so that the floatable crane can be at the position required for construction effectively, hydraulic plate piles can be inserted quickly, and the operation efficiency is improved.

Description

technical field [0001] The present invention relates to hydraulic sheet pile insertion equipment in the technical field of hydraulic inserts and construction machinery, in particular to a hydraulic insertable floating crane for inserting hydraulic sheet piles, which can be used for construction operations under different working conditions Among them, it can meet the actual construction requirements of different working conditions, and complete the insertion of hydraulic sheet piles into the soil with high quality and high efficiency. Background technique [0002] At present, the common hydraulic plate crane used for inserting hydraulic sheet piles is a hydraulic plate balance crane, which includes a double-body pontoon, a connecting frame is installed on the double-body pontoon, and both ends of the upper part of the connecting frame are installed There is a turntable on which a hoist, boom and pulley rope system are installed, and lifting legs and pressure-bearing buoyancy...

AI Technical Summary

Problems solved by technology

This kind of hydraulic sliding plate crane has the characteristics of automatic balance, and can be widely used in hydraulic sliding plate projects in rivers, lakes and seas, but there are the following problems in construction operations: 1) It needs to be moved frequently to reduce the impact of soil on the lifting legs The lifting function of the lifting legs can be realized only by the adsorption force; 2) Once the double-body pontoon and the lifting legs are damaged by accidents and flooded, they will not be self-floating; 3) The hoist and pulley rope system is frequently manipulated and moved. Not only the labor intensity of the construction personnel is high, the construction safety of the construction personnel is not guaranteed, but also the efficiency is extremely low; 4) Since the construction operation environment is usually harsh, often affected by wind, waves and working conditions, the working state is extremely unstable, so this hydraulic plate crane It is necessary to overcome the insufficient structural strength of the slewing bearing, the boom, and the lifting leg to complete the insertion of the hydraulic sheet pile; 5) The length of the boom is limited and there is no counterweight, which leads to the limited lifting range of the hydraulic plate crane. Does not meet the construction requirements of different working conditions, poor applicability

To sum up, the existing hydraulic plug-in cranes not only have extremely low working efficiency, it is difficult to guarantee the safety of insertion, but also have poor applicability, and are very inconvenient to use and maintain

Especially in terms of work efficiency and security, it is particularly outstanding, and it has not been well resolved at present.
