Pressure-bearing rotary support device for construction

Abstract

The invention relates to a pressure-bearing rotary support device for construction. The pressure-bearing rotary support device for construction comprises a rotating disk, a supporting base and a clamping mechanism. The rotating disk is disposed on the supporting base, the supporting base is internally provided with a supporting component, and the clamping mechanism is disposed at the periphery ofthe supporting base. A supporting block is arranged in the supporting base, and a plurality of sliding holes are formed in the supporting block. The rotating disk is connected to the upper part of thesupporting block, the middle part of the supporting block is connected with a central ejector rod, and a supporting ejector rod is arranged in each sliding hole. The central ejector rod is in contactwith the middle part of the rotating disk, and the supporting ejector rods are in contact with the rotating disk. The supporting base comprises an annular supporting frame, and pushing holes are formed in the inner wall of the supporting frame. The clamping mechanism comprises a connecting disk, the outer edge of the connecting disk is fixedly provided with an annular fixing frame, and a plurality of clamping holes corresponding to the pushing holes are formed in the fixing frame. After being bent, the supporting ejector rods penetrate through the pushing holes, and are fixed in the clampingholes. The inner side wall of each clamping hole is connected with a clamping cam bit, the clamping cam bits are connected with swing arms, and the swing arms are connected with a driving ring, and the fixing frame is in linear drive connection with the driving ring.

Description

technical field [0001] The invention relates to a pressure-bearing rotary supporter for construction, which belongs to the rotary pressure-bearing device used in construction equipment. Background technique [0002] In some areas that require rotating pressure such as large-scale tower cranes and jacks, traditionally, large-scale pressure-bearing bearings or static contact friction disc structures are used for support; bearings are easily damaged due to excessive impact due to their design. The deformation of the rollers will seriously reduce the smoothness of the rotation of the deformed rollers, affecting the normal rotation support of the equipment. At the same time, the friction disc structure is also easy to reduce the smoothness of rotation due to impurities mixed in, so the traditional rotation support structure is generally The usage is poor.
