Abstract
The invention relates to an automatic tower crane concrete pumping system, which comprises a tower crane and a concrete conveyor used for conveying concrete, wherein the concrete conveyor is arranged under a crane jib of the tower crane and is flexibly connected with a lifting hook on the crane jib; the concrete conveyor comprises a vertical delivery pipe and a horizontal rigid delivery pipe communicated with the vertical delivery pipe through a horizontal rotary pipe joint; and the free end of the rigid delivery pipe is provided with a concrete casting pipe. The automatic tower crane concrete pumping system has smaller delivery resistance, the horizontal rigid delivery pipe rotates in a horizontal plane, and a delivery barrier caused by bending the delivery pipe in a vertical plane in the prior art is avoided. Meanwhile, the tower crane is reformed a little, steps such as arranging a horizontal track and a driving device on the tower crane and the like are saved, and the casting distance can be prolonged according to requirements.
Description
Technical field
The invention belongs to the tower crane technical field, especially relate to a kind of automatic concrete tower crane pumping system.
Background technology
At present, in the construction of building trade, various concreting methods and equipment being arranged, is a kind of mode comparatively commonly used with tower crane with building that pipeline combines.
CN2266625Y discloses the device of delivering concrete on a kind of building tower crane, by pumping plant, straight tube, fixing cutting ferrule, bend pipe, movable cutting ferrule, on, lower supporting frame, working platform is formed, straight tube is fixed on the body of the tower inboard, to slewing tower bearing bottom, connect straight tube by racecourse bend, import in the slewing tower through lower supporting frame, but connect close pattern bend with the active card cover, by the upper support frame, connect horizontal bend pipe with fixing cutting ferrule, and be fixed on the slewing tower, connect bend pipe with the active card cover, band pin bend pipe, discharge nozzle, band pin bend pipe is provided with attached Scooter with arm and is connected, and discharge nozzle is suspended on the suspension hook, and the lower end also is provided with flexible pipe.This scheme can to required place, improve concreting to have built efficient in the effective length scope of tower crane arm.
CN2219928Y discloses the dual-purpose machine of a kind of self-elevating tower crane continuous casting, on the basis that does not change tower machine original structure and function, increase a vertical transport pipe and a cover can be made the conveying device of hanging that moves horizontally on tower machine cantilever, in its concrete outlet end lifting arbitrarily, also can in the plane of arbitrary height, do the rotation of 90 degree, the swing of 180 degree about can also doing.This class technical scheme can be avoided the dead angle occurring building, satisfies the construction requirement of various storied building structures.
Through further analyzing as can be known, all there is common defective in above-mentioned two kinds of technical schemes:
1, the concrete conveying pipe that is installed in arm below will be done the bending rotation of respective angles according to casting position in fore-and-aft plane, and concrete viscosity is bigger, and its resistance in course of conveying is bigger.For reducing resistance, just need the length of unit conveyance conduit longer, but long unit conveyance conduit when vertically bending (especially when building) a little near the body of the tower position building body below inevitable and the arm clash.Thereby, the length of the unit conveyance conduit in CN2266625Y and the CN2219928Y technical scheme must be shorter, this causes the quantity of unit conveyance conduit more again, the quantity of bending place is also more, cause concrete resistance in course of conveying bigger, the concrete pump acc power that needs is also bigger, has increased cost of production.
2, the transformation that need carry out original tower crane is more, structure is comparatively complicated, need install auxiliary coaster as CN2266625Y on arm, the conveying device of hanging that hangs on the tower horn just comprises by fly block, extension pulley, connection steel pipe, bend pipe and steel pipe loose joint first-class.
Summary of the invention
Technical problem to be solved by this invention is that the transporting resistance of existing automatic concrete tower crane pumping system is bigger, and is simultaneously more for the transformation of tower crane.
For this reason, technical scheme of the present invention is:
