Description
Technical field
The present invention relates to a kind of hanging apparatus using while setting up steel tower, specifically a kind of rotating pole.
Background technology
In transmission line construction, need to set up high voltage iron tower, it is the steel tower of four jiaos of types of the trussed construction that assembles of tower material by some steel poles that high voltage iron tower is generally four groups.While setting up high voltage iron tower, first on ground, build up basis and column foot, then progressively upwards build tower material member.
When high voltage iron tower sets up certain altitude, for the height that being transported to of each member safety set up, need to carry out with lifting device the tower material of handling high voltage iron tower.But, due to four groups of trussed constructions of high voltage iron tower from distant, and the place of setting up high voltage iron tower is generally with a varied topography, the restriction of the height being lifted by crane and the condition of construction plant, common crane is difficult to meet instructions for use, and the general rocker pole that uses coordinates the acting in conjunction erection tower materials such as hoist engine, assembly pulley and wire rope at present.
Rocker pole comprises mobile jib, rocking arm and for the fixing support of mobile jib and rocking arm.Support is fixedly installed on the ground, center of high voltage iron tower, and the bottom of mobile jib is fixed on the center of cradle top surface, and rocking arm is hinged on a side of cradle top surface mobile jib.The top socket rotary cover cap of mobile jib, rotary cover cap is fixedly connected with ground by bracing wire, keeps the stress balance of mobile jib and rocker pole integral body.Two leading blocks are set on the end face of the outside of rotary cover cap, utilize the wire rope of the hoist engine traction that is placed on ground first on one of them leading block, and across another excessively corresponding leading block, be connected with rocking arm.The top socket cover cap of rocking arm arranges load-bearing pulley and lifting pulley on cover cap, and wherein load-bearing pulley is corresponding with the leading block on mobile jib, is wound around and draws the wire rope to rocking arm by the leading block on mobile jib; The wire rope being wound around on lifting pulley is connected with member, and the wire rope other end plays tower crane material by the draw of hoist engine.While carrying out the installation of rocker pole before use, first mobile jib is vertically fixed on to steel tower center, the drive by hoist engine afterwards, utilizes the draw of wire rope, the tower material that is lifted on rocking arm top is promoted to the height needing.In the time need to adjusting the height of rocking arm, by control, be wrapped in the folding and unfolding of the wire rope on mobile jib leading block, the pin joint of rocking arm bottom of take is center of rotation, rocking arm length is that radius is adjusted.Rocker pole is when lifting operation, the tower material being lifted by crane is all generally under rocking arm vertical, can not carry out level angle skew, if in the time of need to horizontally rotating displacement, need to be to mobile jib, rocking arm and support again dismounting, whole adjustment mobile jib and rocking arm rotate, troublesome poeration, need to waste a large amount of manpowers, because the weight of rocker pole is large, also easy initiation potential.
Summary of the invention
The Multifunctional rotary pole that the technical issues that need to address of the present invention are to provide a kind of simple in structure, easy accessibility, can carry out easily 360 ° and rotate freely, and meets the needs that horizontally rotate displacement.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
Multifunctional rotary pole, comprise that top is provided with the rocking arm that the mobile jib of leading block, top arrange load-bearing pulley and lifting pulley, also comprise that a central vertical is provided with the base of column spinner, on described base around the uniform some rollers of column spinner, base top arranges and is socketed on column spinner and the rotating seat contacting with roller, described rotating seat corresponding rotation Zhu position is fixedly installed a connection cover, the bottom-hinged of described mobile jib is connecting Zhao top, and described rocking arm is hinged on the sidewall or rotating seat that connects cover.
Further improvement of the present invention is: on rotating seat, be also fixedly installed two groups of wiring axles and a fixed pulley.
Further improvement of the present invention is: described connection cover comprises the junction plate I that is fixedly installed on column spinner top by some gripper shoes, in junction plate I, be fixedly installed four-way seat, mobile jib is hinged on four-way Zuo top, and rocking arm is hinged on the sidewall or rotating seat of four-way seat.
Further improvement of the present invention is: the end face of described four-way seat is bolted flat base is set, and mobile jib bottom is fixedly connected with lower connecting base, and the upper vertical of described flat base arranges two relative mounting ears, between two mounting ears, fixed axis is set; The bottom of lower connecting base arranges fixedly ear of suit two of fixed axis, and the middle part of fixed axis is radially run through a through hole is set, fixedly between ear setting through the bearing pin of through hole on fixed axis.
Owing to having adopted technique scheme, the technological progress that the present invention obtains is:
The present invention not only can carry out 360 ° and rotate freely easily for the tower material lifting of vertical direction simultaneously, meets differing heights and different angles lifting requirements of one's work in steel tower erection process.Forming each component of the present invention can transport separately, and weight is little, simple in structure, and easy accessibility has shortened the engineering time, has improved efficiency of construction.Not limited by landform, the scope of application is wide.Utilize conveniently erection tower material of the present invention, lift simple to operately, saved a large amount of manpower and materials, reduced engineering cost.
The four-way seat being fixedly installed on junction plate connects as one mobile jib and rocking arm, and what while alleviating rotation, produce rocks, time saving and energy saving, eliminates safe hidden trouble.Be fixed on flat base and the fixedly hinged setting of lower connecting base of mobile jib on four-way seat, when being rotated, mobile jib is played to cushioning effect, when being subject to installation site restriction and causing rotating seat not to be horizontally disposed with, can guarantee the mobile jib state of being still kept upright, when lifting operation, keep steadily of centre of gravity, assurance equipment and personal security.
