Abstract

A crane provided with a split rotary supporting device comprises a supporting base plate module, a crane table module, a tower body, an electrical control module, a horizontal supporting arm, a swinging supporting arm, a jib loading boom, a tower body stay cable and a draw bar. The crane table module is mounted above a supporting base plate via the split rotary supporting device, the tower body is mounted on a crane table in a pin shaft connection mode, the electrical control module is mounted on the crane table, the horizontal supporting arm, the swinging supporting arm and the jib loading boom are disposed at the top of the tower body, the tower body stay cable is connected between the crane table module and the top of the tower body, and the draw bar is connected to the crane table module and one end of the horizontal supporting arm. The crane is characterized in that the split rotary supporting device comprises an intermediate body, a gear ring and a rotary driving mechanism, wherein the intermediate body is mounted below the crane table module via a pin shaft convenient to be assembled and disassembled, the gear ring is mounted on a rotary disc bearing arranged on the bottom surface of the intermediate body, the rotary driving mechanism is mounted on the intermediate body and consists of a power driving mechanism and a driving gear meshed with the gear ring, and the gear ring is combined with the supporting base plate module via a high-strength bolt.

Description

Be provided with the hoisting crane of split type slewing supporting device
Technical field
The utility model relates to a kind of hoisting crane, specially refers to a kind of hoisting crane that is provided with split type slewing supporting device.
Background technology
Along with the sustained and rapid development of national economy, the every field of modernization construction has proposed such as quick assembling, maneuverability, has been convenient to transportation large-scale hanging device, has a series of new demands such as multiple ground comformability.Present situation in China is that the speed of development of large-scale hanging device far lags behind development and national economy speed, so have to adopt external equipment in the big construction item of a lot of industries, has increased construction cost greatly.
Summary of the invention
The purpose of this utility model just at the development of the national economy to the new demand of hanging device and a kind of hoisting crane that is provided with split type slewing supporting device is provided.Described hoisting crane comprises the hoisting crane of all-hydraulic traveling gear and device, and that this hoisting crane not only has is low from heavy and light, cost, maneuverability, characteristics that transition is fast, especially is fit to needs frequent construction project of changing operating location in short range and uses.
The purpose of this utility model can realize by following technique measures:
The hoisting crane that is provided with split type slewing supporting device of the present utility model, this hoisting crane comprises the support chassis module, be installed in the board module of support chassis top by split type slewing supporting device, be installed in body of the tower on the board by the bearing pin ways of connecting, and be installed in electrical control module on the board, be arranged on horizontal brace, swing brace, the crane arm at body of the tower top, and be connected body of the tower suspension cable between board module and the body of the tower top, be connected the pull bar of board module and horizontal brace one end; Wherein: described split type slewing supporting device comprise by easy-to-mount bearing pin be installed in board module below intermediate, be installed in the gear ring on the turntable bearing that is provided with on the intermediate bottom surface, be installed in the rotary motion mechanism on the intermediate; Described rotary motion mechanism is made up of power-driven mechanism and the driven wheel that is meshed with gear ring; Described gear ring is by combining with the support chassis module by high strength bolt.
The beneficial effects of the utility model are as follows:
This connection mode of the present utility model can make realize between board module and the split type slewing supporting device fast easily in conjunction with or separate, for transition, the assembled on site of hoisting crane provides convenience.
Description of drawings
Fig. 1 is an overall construction drawing of the present utility model.
Fig. 2 is the structure and the annexation figure of split type slewing supporting device among Fig. 1.
Among the figure: driver's cab, 11-elevator unit, 12-power engine, 13-crane arm side direction suspension cable, 32-intermediate, 33-revolution driving, 34-gear ring under A-support chassis module, the split type slewing supporting device of B-, C-board module, D-body of the tower, the horizontal brace of E-, F-swing brace, G-crane arm, 1-suspension hook, 2-automatic picking off and hanging hook device, 3-drag-line, the anti-hypsokinesis strut of 4-, 5-suspension cable, 6-hoist rope, 7-pull bar, the last driver's cab of 8-, 9-clump weight, the 10-.
The specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As Fig. 1, shown in 2, the hoisting crane that is provided with split type slewing supporting device of the present utility model, this hoisting crane comprises support chassis module (A), be installed in the board module (C) of support chassis top by split type slewing supporting device (B), be installed in body of the tower (D) on the board by the bearing pin ways of connecting, and be installed in electrical control module on the board, be arranged on the horizontal brace (E) at body of the tower top, swing brace (F), crane arm (G), and be connected body of the tower suspension cable (5) between board module and the body of the tower top, be connected the pull bar (7) of a board module and horizontal brace (E) end; Wherein: described split type slewing supporting device (B) comprise by easy-to-mount bearing pin be installed in board module (C) below intermediate (32), be installed in the gear ring (34) on the turntable bearing that is provided with on intermediate (32) bottom surface, be installed in the rotary motion mechanism (33) on the intermediate (32); Described rotary motion mechanism (33) is made up of power-driven mechanism and the driven wheel that is meshed with gear ring; Described gear ring (34) is by combining with support chassis module (A) by high strength bolt.Because high strength bolt quantity is many, and complexity is installed, no longer dismounting generally speaking, split type slewing supporting device and support chassis module (A) are transported as a whole during transportation.
