Crane operating mechanism and using method thereof

Abstract

The invention discloses a crane operating mechanism and a using method thereof. The crane operating mechanism comprises balance beams, jacking hydraulic cylinders, operating wheels and horizontal wheels; the number of the balance beams is two; the two balance beams are oppositely arranged on two sides of a main arm frame at intervals and are connected with the main arm frame through arm frame pinshafts; the operating wheels are connected to the balance beams through the jacking hydraulic cylinders and can be driven by the jacking hydraulic cylinders to move up and down to be lower than the bottom faces of the balance beams or higher than the bottom faces of the balance beams; the horizontal wheels are connected to two ends of the balance beams; and the vertical positions of the horizontalwheels are adjustable. According to the crane operating mechanism and the operating method thereof, the operating wheels and the horizontal wheels which can stretch and contract in a vertical direction are arranged; hoisting load cannot act on the operating wheels and the horizontal wheels; hoisting capacity can be improved; the operating wheels and the horizontal wheels can be prevented from being damaged or abraded due to long-term force bearing; the service lives of the operating wheels and the horizontal wheels are prolonged; and under a moving working condition, a crane is moved throughthe cooperation of the operating wheels, the horizontal wheels and rails, and therefore, operating stability is improved.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a crane operating mechanism and a use method thereof. Background technique [0002] In order to meet the lifting tasks under different working conditions and the needs of putting the jib back on the deck, the offshore jib crane needs to run along the track on the deck. Due to the heavy weight of the equipment, the large lifting capacity and the limitation of the space on the ship, if the Conventional cart running mechanism will require too many wheels, and also need to improve deck support strength, which is not economical. In addition, frequently applying a heavy load to the wheel device will increase the wear of the wheel, shorten the service life, and increase the maintenance cost. Therefore, it is necessary to design a new type of operating mechanism to meet the above conditions at the same time. Contents of the invention [0003] In order to solve the above-me...
