Description
Technical field
The utility model relates to a kind of hoisting crane, specially refers to a kind of telescopic tower hoisting crane.
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 telescopic tower hoisting crane is provided.Described hoisting crane comprises all-hydraulic traveling gear telescopic tower hoisting crane, 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:
Hoisting crane of the present utility model 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 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 body of the tower is the multi-stage telescopic body of the tower, by some joints from the bottom to top the member that successively decreases of cross sectional dimensions be sleeved on together; Body of the tower is in when stretching out state, interconnects by shearing-resistance blocks, high strength bolt between first order body of the tower and the second stage body of the tower, interconnect by shear-pin between all the other bodies of the tower at different levels, and shear-pin one end is connected with the shear-pin push cylinder.
The L-shaped structure in the vertical section of shearing-resistance blocks described in the utility model, and its stile partly is installed in the draw-in groove that body of the tower corresponding position, the second stage processes, and combine with second stage body of the tower by high strength bolt, its base combines by the upper surface of high strength bolt with first order body of the tower.
The rear end of shear-pin described in the utility model combines with shear-pin push cylinder in being arranged on body of the tower by attaching parts, front end matches with pivot pin mounting hole on being separately positioned on corresponding two-stage body of the tower member, and this structure can realize the Fast Installation and the dismounting of shear-pin.
The beneficial effects of the utility model are as follows:
Because the multi-stage telescopic body of the tower in the utility model is when stretching out state, adopt shearing-resistance blocks and shear-pin to make it to interconnect respectively between neighbouring level member, this just makes body of the tower can be combined into multiple operating altitude according to the needs of actual condition, to satisfy the different operating requirement for height, the quick-assembling and the dismounting of multi-stage telescopic body of the tower have also been realized simultaneously, and multistage body of the tower is sleeved on together, for integral transportation is provided convenience.
