Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, but the embodiments of the present invention are not limited thereto.

Example 1:

referring to fig. 1-6, a slewing crane device of a hydraulic link comprises a gantry 1, a hydraulic push rod 2, a hydraulic pump station unit 3, a slewing bearing device 4, a slewing arm 5, a slewing crane hoisting mechanism 6, a gripper device 7, a first limit switch 8, a second limit switch 81, a slewing arm support, a link mechanism, an oil cylinder hinged support 11, a shutdown anchoring ear plate 12, an anchoring pin shaft 13 and an anchoring pin hole 14.

Fixed mounting has the slewing arm support on the 1 top lateral wall of portal, the slewing arm support includes install bin 9, go up support 92, lower support 93, one side fixed mounting of install bin 9 is on the portal, go up support 92, lower support 93 is located the opposite of install bin 9, the welding of lower support 93 is at the install bin 9 lower extreme, it installs in install bin 9 upper end through the bolt to go up support 92, at last 92 and the lower support 93 vertical installation of slewing bearing device 4, be provided with a mounting hole 91 on the install bin 9 lateral wall, the effect of mounting hole 91 is convenient welding or bolted connection.

One end of the revolving arm 5 is sleeved on the shaft of the revolving bearing device 4, so that the revolving arm 5 rotates around the revolving bearing device 4, the gripper device 7 is positioned at the other end of the revolving arm 5, the revolving crane hoisting mechanism 6 is detachably connected or welded or bolted on the revolving arm 5, and the gripper device 7 can be hoisted or put down through the revolving crane hoisting mechanism 6.

The rotation of the swivel arm 5 is achieved by: an oil cylinder hinged support 11 is fixedly installed on the portal frame, the oil cylinder hinged support 11 is hinged with one end of a hydraulic push rod 2, the hydraulic push rod 2 can rotate relative to the oil cylinder hinged support 11 in the horizontal direction, the connecting rod mechanism comprises a first connecting rod 10, a second connecting rod 101, a first hinged support 102 and a second hinged support 103, the first hinged support 102 is fixedly installed on the portal frame 1, the second hinged support 103 is fixedly installed on the revolving arm 5, one end of the first connecting rod 10 and one end of the second connecting rod 101 are coaxially hinged with the other end of the hydraulic push rod 2, the other end of the first connecting rod 10 is hinged with the first hinged support 102, and the other end of the second connecting rod 101 is hinged with the second hinged support 103; the first link 10 and the second link 101 are always opened at a certain angle during the rotation process, because the first link 10 and the second link 101 are overlapped and cannot rotate. When the revolving arm 5 rotates, the hydraulic push rod 2 extends out of the push rod, and since the other end of the first connecting rod 10 is hinged with the first hinge support 102 fixed on the gantry 1, force is transmitted to the second connecting rod 101, and the second connecting rod 101 drives the revolving arm 5, so that the revolving arm 5 is pushed to rotate, and in the process, the opening angle of the first connecting rod 10 and the second connecting rod 101 is gradually increased.
