Abstract
The utility model relates to a marine unlimited rotary cargo lifting crane, which comprises a cylinder frame, a crane main machine and a hydraulic motor; it is characterized in that the device also comprises a slip ring and a universal joint coupler; the hydraulic motor is connected with a hydraulic pump on the crane host through a universal joint coupler, and a slip ring is arranged outside the universal joint coupler and used for connecting the crane host with a power cable. The utility model has the advantages of enable the unlimited gyration of loop wheel machine host computer in the barrel frame and reduce hydraulic motor and hydraulic pump erection joint requirement.
Description
Technical Field
The utility model relates to a marine loop wheel machine especially relates to a marine unrestricted gyration cargo lifting loop wheel machine.
Background
At present, the marine crane mainly comprises a barrel frame, a crane host and a hydraulic motor, the crane host is installed on the barrel frame, the hydraulic motor is arranged in the barrel frame below the crane host, the hydraulic motor is connected with a hydraulic pump on the crane host, when the crane host is installed, the center of a hydraulic motor rotating shaft is also connected with the center of the hydraulic pump rotating shaft very accurately, therefore, the processing and the installation of a rotary table of the crane host and the barrel frame are required to be accurate to 0.05mm, the cost of installation and production is greatly improved, and meanwhile, a power cable is connected between the crane host and a ship body, so the crane host can only carry out limited rotation on the barrel frame, otherwise, the cable is easily broken.
Disclosure of Invention
To the above shortcoming, an object of the utility model is to provide an it can make the hoist host computer unrestricted gyration and reduce the marine unrestricted gyration cargo lifting hoist of hydraulic motor and hydraulic pump erection joint requirement in the barrel frame.
The technical content of the utility model is that a marine unlimited rotary cargo lifting crane comprises a cylinder frame, a crane main machine and a hydraulic motor; it is characterized in that the device also comprises a slip ring and a universal joint coupler; the hydraulic motor is connected with a hydraulic pump on the crane host through a universal joint coupler, and a slip ring is arranged outside the universal joint coupler and used for connecting the crane host with a power cable.
Compared with the prior art, the utility model the advantage that has do: the utility model discloses a sliding ring design for the hoist can not receive the rotatory restriction of cable, can unlimited gyration, and adopted the hydraulic pump on universal joint coupling connection hydraulic motor and the loop wheel machine host computer, make the revolving platform on the loop wheel machine host computer and the processing and the installation of barrel frame need not accurate 0.05mm to, make the processing installation more simple and convenient.
