Special pile inverting frame for trolley

Abstract

The invention discloses a special pile inverting frame for a trolley. The special pile inverting frame for the trolley comprises a base, a pile inverting arm, a pile holding arm group, a locking device, a first hinging point and a pile inverting collecting and pushing device; and the pile holding arm group comprises two pile holding arms. The pile inverting collecting and pushing device comprisesa pile inverting oil cylinder, a second hinging point and a third hinging point. The cross section of the pile inverting arm is in an L shape in one direction. The special pile inverting frame for thetrolley is in an arm surrounding shape; the height of the pile inverting arm is as same as that of a working platform on the trolley in a fixed state; and compared with an original jacking frame, thespecial pile inverting frame for the trolley has the advantages of short climbing distance, low height and high safety performance. Holes do not need to be formed in a steel pile and the pile inverting frame so that the rigidity of the steel pile and the rigidity of the pile inverting frame can be guaranteed. Meanwhile, the special pile inverting frame for the trolley can be of inverted type andcan be inverted while not in use without affecting the vision of a sailor during the sailing of a hull; and therefore, the safety performance is high, the practicability is high, the operation is simple and convenient, a lot of labor is saved by using a mechanical principle, and the working efficiency of the hull is enhanced.

Description

technical field [0001] The invention relates to the field of positioning pile trolley systems, in particular to an inverted pile frame fixing device. Background technique [0002] Dredgers are responsible for clearing the silt in waterways and rivers so that other ships can pass smoothly. Since dredgers operate in moving water, the hull needs to be positioned before operation. The positioning pile trolley system has become an important dredging equipment for bucket wheel and cutter suction dredgers. It is installed in the groove of the bow or stern. Generally, a ship contains two positioning steel piles, respectively. Called the main pile and auxiliary pile. The main pile is installed on the trolley and plays the main role, and the auxiliary pile mainly plays an auxiliary role when advancing during the dredging process. The auxiliary pile is installed on the left or right side of the main pile. [0003] The main pile is first erected and inserted into the seabed (river be...

AI Technical Summary

Problems solved by technology

In this method, the operation is extremely cumbersome during the fixing process, the hole positioning accuracy is high, and the safety of the staff cannot be guaranteed at the same time.

In addition, since the role of the steel pile is to bear the load of the hull, after the hole is opened on it, it is very easy to affect its overall rigidity, and there are serious deficiencies
