Abstract

The utility model discloses a self-lifting tower crane continuous casting dual-purpose machine. Some mechanisms of a tower machine is used to be compatible on the tower machine, under the condition that the primary structure and function of the tower machine is not changed, a vertical conveying pipe and a set of suspension delivery devices which can make horizontal movement on the cantilever of the tower machine are added. At the outlet end of concrete, the utility model can randomly rise and fall, make the rotation of 90 DEG of any height and make the swinging of 180 DEG laterally. Only in the way, the dead angle of pouring can be avoided. The utility model can satisfy the construction requirements of various building structures, no matter whether continuous pouring operation is carried out, the normal operation of the tower machine is not influenced, the continuous pouring operation and the normal operation of the tower machine can be carried out both alone and synchronously, mutually uninfluenced in construction, which reaches the purpose of two purposes for one machine.

Description

The dual-purpose machine of self-elevating tower crane continuous casting

The utility model relates to a kind of in the high-building construction of frame construction, to binding, not only can realize concrete continuous cast but also the dual-purpose plant equipment that can carry out the tower crane operation from the basis of building.

At present, in the construction of building trade, various concrete pouring ways and equipment are arranged, its operating type is concluded two classes: cart type and bucket formula (or bucket type), the former rises to corresponding floor with concrete trolley is housed from ground, personnel selection is tried hard to recommend out, pours into a mould by car; The latter uses tower crane, between ground and building one barrel of one barrel of ground back and forth lifting pour into a mould, use above-mentioned job practices, want further to improve work efficiency and have very big difficulty.

The purpose of this utility model is to provide a kind of self-elevating tower crane continuous casting dual-purpose machine, and it and tower machine both can use separately, also can work simultaneously, were independent of each other in the construction.

The purpose of this utility model is achieved in that increasing a vertical transport pipe and a cover on the tower machine can make the conveying device of hanging that moves horizontally on tower machine cantilever, the port of export in conveying device, but oscilaltion and moving horizontally, can in arbitrary plane, do 360 ° rotation, so just can avoid pouring into a mould the dead angle, satisfy the construction requirement of various building layer structure.

This device is by vertical transport pipe (17), pipeline transition apparatus (12), hanging conveying device and conical pipe chain lifting device forms, wherein: hang conveying device and comprise by fly block (1), connect steel pipe (3), extension pulley (4), bend pipe (10) and steel pipe movable joint (11), the conical pipe device comprises winch (7), steel cable (6), pipe arm (8) and conical pipe chain (9), every group of below by fly block is fixed with rigidity elbow (21), with be connected by movable joint between the steel pipe, the other end of bend pipe has trapezoidal thread and sealing ring, and leave the gap of 3 screw buckles between the joint, the below of extension pulley (4) is fixed with interior pipe, ball bearing is equipped with at its two ends, fix with the screw thread door, outer tube is swung in 180 ° of scopes of interior pipe, by locating piece (23) and gusset (24) location, conical pipe (28) is connected with the pipe arm by flange with pipe arm (27), lacing wire (26) and to spend blue nut be take-up device, be fixed with two chain rails (37) in the below of cantilever (29), by disc type brake motor (33), the transmission mechanism that harmonic wave speed reducing machine (32) and sprocket wheel (34) are formed, drive balladeur train (35) rectilinear motion by vertical two-wheel (30) and horizontal wheels (31), the wire rope (38) of tower machine dolly is led by support roller (36); The conical pipe chain of forming by top conical pipe (42), middle conical pipe (40) and terminal conical pipe (39), by winch (45), wire rope (44) and quarter block (43), be welded with the channel suspending rail of shutting at two (41) in the both sides of each conical pipe, inner spring base and the riveted joint of pipe arm, spring and adjusting nut can make steel ball press bottom land; Steel ball seat and elbow (53) are fixed on from rising on the frame (54), and the curved group head of pipe group links to each other with elbow (53) by sealing ring (50) with steel ball flange (52).

The utility model compared with prior art, can with tower machine compatibility, do not change tower machine original function, no matter whether continuous pouring is carried out, and does not influence the work of tower machine, reaches the effect of dual-use.
