Description

Multifunctional rotary derrick
Technical field
The present invention relates to a kind of hanging apparatus used when setting up steel tower, a kind of rotating pole specifically.
Background technology
In transmission line construction, need to set up high voltage iron tower, the steel tower of high voltage iron tower to be generally four groups by some steel poles be four angle-style of the trussed construction that tower material assembles.During erection high voltage iron tower, first build up basis and column foot on ground, then progressively upwards build tower material component.
When high voltage iron tower sets up certain altitude, in order to the height being transported to erection by each component safety, need to use lifting device to carry out the tower material of handling high voltage iron tower.But, due to high voltage iron tower four groups of trussed constructions from distant, and the place of erection high voltage iron tower is generally with a varied topography, the restriction of the height 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 the support for fixing 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 the 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 entirety.The end face outside of rotary cover cap arranges two leading blocks, utilizes the wire rope of the hoist engine traction being placed on ground first around on one of them leading block, and across another corresponding leading block, be connected with rocking arm.The top socket cover cap of rocking arm, cover cap arranges load-bearing pulley and lifting pulley, and wherein load-bearing pulley is corresponding with the leading block on mobile jib, is wound around by the leading block traction on mobile jib to the wire rope of rocking arm; The wire rope that lifting pulley is wound around is connected with component, and the wire rope other end plays tower crane material by the draw of hoist engine.When carrying out the installation of rocker pole before using, first mobile jib is vertically fixed on steel tower center, afterwards by the drive of hoist engine, the draw utilizing wire rope, the tower material being lifted on rocking arm top is promoted to the height of needs.When needing the height adjusting rocking arm, by controlling the folding and unfolding of the wire rope be wrapped on mobile jib leading block, with the pin joint bottom rocking arm for center of rotation, rocking arm length is that radius adjusts.Rocker pole is when carrying out lifting operation, by the tower material lifted by crane be all generally rocking arm vertical immediately below, level angle skew can not be carried out, if when needing to carry out horizontally rotating displacement, need mobile jib, rocking arm and support again dismounting, integrated regulation 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 technical issues that need to address of the present invention are to provide that a kind of structure is simple, the Multifunctional rotary derrick of easy accessibility, can carry out 360 ° easily and rotate freely, meet the needs horizontally rotating displacement.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
Multifunctional rotary derrick, comprise the rocking arm that top is provided with the mobile jib of leading block, top arranges load-bearing pulley and lifting pulley, also comprise the base that a central vertical is provided with column spinner, around the uniform some rollers of column spinner on described base, arrange above base and be socketed in the rotating seat contacted on column spinner and with roller, the position of described rotating seat corresponding rotation post is fixedly installed a connection cover, the bottom-hinged of described mobile jib is connecting the top of cover, described rocking arm be hinged on connect cover sidewall or rotating seat on.
Further improvement of the present invention is: rotating seat is also fixedly installed two groups of wiring axles and a fixed pulley.
Further improvement of the present invention is: the described cover that connects comprises and is fixedly installed on junction plate I above column spinner by some gripper shoes, junction plate I is fixedly installed four-way seat, mobile jib is hinged on the top of four-way seat, on the sidewall that rocking arm is hinged on four-way seat or rotating seat.
Further improvement of the present invention is: the end face of described four-way seat is bolted and arranges flat base, is fixedly connected with lower connecting base bottom mobile jib, and the upper vertical of described flat base arranges two relative mounting ears, arranges fixed axis between two mounting ears; The bottom of lower connecting base arranges two fixing ears of suit fixed axis, and the middle part of fixed axis is radially run through and arranged a through hole, arranges the bearing pin through through hole on fixed axis between fixing ear.
Owing to have employed technique scheme, the technological progress that the present invention obtains is:
The present invention not only may be used for the tower material lifting of vertical direction, can carry out 360 ° easily simultaneously and rotate freely, and meets differing heights and different angles lifting requirements of one's work in steel tower erection process.Each component of composition the present invention can transport separately, and weight is little, and structure is simple, and easy accessibility, shortens the engineering time, improves efficiency of construction.Do not limit by landform in use, the scope of application is wide.Utilize the present invention can conveniently erection tower material, lift simple to operate, save a large amount of manpower and materials, reduce engineering cost.
Mobile jib and rocking arm connect as one by the four-way seat that junction plate is fixedly installed, and what produce when alleviating rotation rocks, time saving and energy saving, eliminates safe hidden trouble.Be fixed on the hinged setting of lower connecting base of flat base on four-way seat and fixing mobile jib, when rotating, cushioning effect is played to mobile jib, when being subject to installation site restriction and causing rotating seat not to be horizontally disposed with, can guarantee that mobile jib still can be kept upright state, keep steadily of centre of gravity when lifting operates, ensure equipment and personal security.
