Abstract
The invention belongs to the field of tower type cranes for buildings, and in particular relates to an improved sustaining wall rod dismantling device of a tower type crane, which comprises a tower type crane balance arm main beam, wherein the lower end of a jib loading boom is hinged with the lower end of a jib loading boom support frame together and is fixedly arranged on the tower type crane balance arm main beam, the upper end of the jib loading boom support frame is hinged with the lower end of a jib loading boom pull rod together, the upper end of the jib loading boom pull rod is hinged with the upper end of the jib loading boom together, the top end of the jib loading boom is provided with a jib loading boom top end pulley, a wire fixed pulley is fixedly arranged on the tower type crane balance arm main beam, a steel rope is connected with the wire fixed pulley, the jib loading boom top end pulley and a lifting hook movable pulley together, and the jib loading boom support frame and the jib loading boom pull rod regulate the hoisting angle of the jib loading boom through a regulating pulley mechanism. By using the improved sustaining wall rod dismantling device, no limit by rotation of the jib loading boom exists, a sustaining wall rod can be dismantled after the improved sustaining wall rod dismantling device is installed in a proper position, thus potential safety hazards of incline pulling and incline hoisting of the tower type crane are eliminated.
Description
Technical field
The invention belongs to tower crane for building field, particularly relate to the stripping assembly of a kind of improved tower crane sustaining wall bar.
Background technology
At present the dismounting of tower crane sustaining wall bar all is to utilize the master winch mechanism of tower machine self to remove, and does not have special device to remove in the equipment that producer dispatches from the factory, in unloading process when dismantling the first road sustaining wall bar; The tower machine can rotate freely, outside conveniently dismantling, and remaining several roads sustaining wall; The tower machine all can not rotate when dismounting; Can not arrive desirable lifting position, so just increase the dismounting difficulty, also certainly will have the situation of pull and hang sideling; Increase the danger of operation, also increased the probability that safety misadventure takes place.
Summary of the invention
Technical matters to be solved by this invention is: when tower crane is removed the sustaining wall bar, do not receive the restriction of crane arm rotation, can carry out the dismounting of sustaining wall bar after installing in place, eliminate the potential safety hazard of tower machine pull and hang sideling.
Solving the problems of the technologies described above the technical scheme that is adopted is: the stripping assembly of a kind of improved tower crane sustaining wall bar; Comprise tower machine equilibrium arm girder; Hinged and fixed being arranged on the tower machine equilibrium arm girder in the lower end of the lower end of crane arm and crane arm bracing frame; The lower end of the upper end of crane arm bracing frame and crane arm pull bar is hinged; The upper end of crane arm pull bar and the upper end of crane arm are hinged, and the top of crane arm is being provided with crane arm top pulley, and the lead fixed pulley is fixedly installed on the tower machine equilibrium arm girder; Steel cable links together through winch and lead fixed pulley, crane arm top pulley and the suspension hook movable pulley that is arranged on tower machine equilibrium arm girder, and the tail end of steel cable is cemented in the upper end of crane arm.Below the suspension hook movable pulley, connecting and playing the weight equalizer bar, crane arm bracing frame and crane arm pull bar are regulated the lifting angle of crane arm through regulating pulley mechanism.Described regulating mechanism is made up of pulley of installing on crane arm bracing frame and the crane arm pull bar hinge-point and fixed adjusting fixed pulley and the steel rope that is arranged on the tower machine equilibrium arm girder; Jig is installed on steel cable, regulates the lifting angle of the length realization adjusting crane arm of steel rope through jig.Two ends at described weight equalizer bar are being provided with through hole.
In the practice, device of the present invention is installed in through removable mode on the tower machine equilibrium arm girder of tower crane, the sustaining wall bar can be removed after dismantling and finishing, and removes to be installed on the tower crane that needs dismounting sustaining wall bar reuse, and is very convenient.
Beneficial effect of the present invention: in use do not receive the restriction of crane arm rotation, can carry out the dismounting of sustaining wall bar after installing in place, eliminated the potential safety hazard of tower machine pull and hang sideling; Because of angle is suitable, in unloading process,, reduced the danger of operation also for the operating personnel has reduced the dismounting difficulty, also reduced the probability that safety misadventure takes place, be worth wideling popularize in China.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is a main TV structure scheme drawing of the present invention.
The specific embodiment
The stripping assembly of a kind of improved tower crane sustaining wall bar; Shown in accompanying drawing 1; Comprise tower machine equilibrium arm girder 1; Hinged and fixed being arranged on the tower machine equilibrium arm girder 1 in the lower end of the lower end of crane arm 5 and crane arm bracing frame 4, the lower end of the upper end of crane arm bracing frame 4 and crane arm pull bar 3 is hinged, and the upper end of the upper end of crane arm pull bar 3 and crane arm 5 is hinged; The top of crane arm 5 is being provided with crane arm top pulley 7; Lead fixed pulley 11 is fixedly installed on the tower machine equilibrium arm girder 1, and steel cable 8 links together with lead fixed pulley 11, crane arm top pulley 7 and suspension hook movable pulley 9 through the winch 2 that is arranged on tower machine equilibrium arm girder 1, and the tail end of steel cable 8 is cemented in the upper end of crane arm 5.Below suspension hook movable pulley 9, connecting and playing weight equalizer bar 10, crane arm bracing frame 4 is regulated the lifting angle of crane arm 5 with crane arm pull bar 3 through regulating pulley mechanism.Described regulating mechanism is made up of pulley and fixed adjusting fixed pulley 6 and the steel rope that is arranged on the tower machine equilibrium arm girder 1 installed on crane arm bracing frame 4 and crane arm pull bar 3 hinge-points; Jig 12 is installed on steel cable, regulates the lifting angle of the length realization adjusting crane arm 5 of steel rope through jig 12.At the two ends of described weight equalizer bar 10 through hole 13 is being set.
In the practice, the inventive system comprises following a few part: the crane arm that assembles, lifting motor, pulley, steel rope and brake part.This device is fixed on the equilibrium arm of tower machine when using; Its principle installs the electric winding plant of a cover additional for the correct position at tower machine equilibrium arm; Can lift by crane, remove member easily; Install crane arm and fixing and adjust hoisting mechanism in actual installation and the operating process, after each parts of inspection and assurance device connect fastening intact and brake intact, Φ 8 steel ropes are worn walk around pulley and hang up properly the dismounting work of carrying out the sustaining wall bar behind the sustaining wall bar wall bar that needs dismounting; After fixedly remove at the two ends of sustaining wall bar, utilize hoisting mechanism that sustaining wall bar safety is fallen earthward.
