The installation process of the high-altitude unmanned guidance installation platform of the single-column steel tube tower is as follows:
(1) in the butt joint process of the upper conical steel pipe 2 and the lower conical steel pipe 3, firstly, the high-altitude unmanned guide mounting platform 1 of the single-column steel pipe tower is mounted on the lower conical steel pipe, the upper conical steel pipe is lifted to the upper side of the mounting platform through a crane, and in the process of gradually descending, the lower end face flange of the upper conical steel pipe is guided to fall into the center of the mounting platform through the guide inclined plane structure, so that the lower end face flange of the upper conical steel pipe and the upper end face flange of the lower conical steel pipe are collinear, the end faces are close, and a certain gap is reserved.
(2) At the moment, two indexing mechanical arm devices 118 on the installation platform move (the mechanical arm has three degrees of freedom and comprises two rotational degrees of freedom and one horizontal movement degree of freedom), the two rotational degrees of freedom rotate clockwise to enable a translation joint 1184 at the tail end of the mechanical arm to contact with the wall surface of the upper-end conical steel pipe, the third degree of freedom is integrated at the tail end of the mechanical arm and is the horizontal movement degree of freedom, the two indexing mechanical arm devices 118 rotate like pliers to symmetrically hold the wall surface of the upper-end conical steel pipe tightly and rotate through respective third horizontal degrees of freedom, and axial rotation of the upper-end conical steel pipe is achieved through friction force.
10 threaded holes (the specific quantity is adjustable) are processed on the flange of the lower end face of the upper end conical steel pipe, and 10 through holes (corresponding to the upper end and adjustable in the specific quantity) are processed on the flange of the upper end face of the lower end conical steel pipe. As the crane does not have any restriction on axial rotation in the process of lifting the conical steel pipe at the upper end, the positions of the threaded holes and the through holes on the upper end surface and the lower end surface are not concentric. The axes of the threaded holes and the through holes on the upper end surface and the lower end surface are collinear through the friction rotation of the two indexing mechanical arm devices 118, the corresponding positions of the upper hole and the lower hole are tracked and identified through cameras (not shown) arranged on the indexing mechanical arm devices 118 in the rotation process, and the mechanical arms are guided to rotate the conical steel pipes on the upper ends.
When the threaded holes of the upper end surface and the lower end surface are collinear with the axes of the through holes, the crane descends to enable the flange of the lower end surface of the upper end conical steel pipe to be in close contact with the flange of the upper end surface of the lower end conical steel pipe.
(3) In the initial state, two different types of bolts (8 flat-head bolts and 2 conical-head bolts respectively, wherein the total number corresponds to the flange bolt holes) are arranged in the mounting platform, the bolt rod is inserted into the bolt hole of the conical steel pipe at the lower end, and the end face of the bolt rod does not exceed the upper end face of the flange.
When the flange on the lower end face of the upper conical steel pipe is completely and firmly connected with the flange on the upper end face of the lower conical steel pipe and the hole positions are aligned, the rotating motor on the bolt positioning and tightening device rotates to drive the motor output gear 124 on the motor output shaft to rotate, the motor output shaft gear is meshed with the annular gear 119 fixed on the mounting platform, and when the motor output gear rotates to drive the rotating motor mounting seat to slide along the semicircular guide groove in the semicircular device, the motor mounting seat can freely move between 0 and 180 degrees.
(4) The motor mounting base of the semicircular device is provided with two degrees of freedom besides a rotary motor, wherein one degree of freedom is a lifting degree of freedom realized by a linear motor, and the other degree of freedom is a rotary degree of freedom realized by a stepping motor.
The output end of a motor shaft of the stepping motor is directly connected with the bolt spanner, and certain axial flexibility is arranged at the joint to prevent the bolt spanner from rigidly colliding with the bolt. The distance between the axis of the output shaft of the stepping motor and the axis of the conical steel pipe is the same as the reference circle diameter of the through hole on the flange at the upper end face of the conical steel pipe at the lower end. The lifting motor drives the stepping motor to lift. The insertion of the shank of the bolt into the head of the bolt is effected.
When the linear motor drives the stepping motor to ascend and insert the bolt rod into the bolt head, the stepping motor rotates to drive the bolt rod to rotate, so that the bolt rotates while ascending, the bolt is inserted into a threaded hole of the flange on the lower end face of the conical steel pipe at the upper end in the ascending process, and the bolt is rotated into the threaded hole and is firmly connected.
When the rotating motor drives the rotating motor base to rotate from the initial position to the position where the axis of the output shaft of the stepping motor is collinear with the axis of the through hole in the flange on the upper end face of the conical steel pipe at the lower end, the rotating motor stops moving, and the linear motor and the stepping motor move to realize thread tightening.
(5) And 8 of the 10 bolts are the same, the end surface of the threaded rod of each bolt is a flat head, and the end surfaces of the other bolts are the same, and the end surfaces of the threaded rods are conical heads. In the working process, at first top 2 conical head bolts and screw, conical head bolt initial mount is in lower extreme circular cone steel pipe up end flange through-hole, and the process that inserts terminal surface flange screw hole under the circular cone steel pipe of upper end gradually through the conical surface can carry out the accurate positioning to terminal surface flange screw hole under the circular cone steel pipe of upper end in the conical head ascending process, and terminal surface flange screw hole provides the guarantee under the convenient follow-up 8 flat head bolts screw in conical steel pipe of upper end that can be accurate smoothly.
The dismounting process of the high-altitude unmanned guidance mounting platform of the single-column steel tube tower is as follows:
after the work is finished, gunpowder in the two fixed explosive bolts is actuated to disconnect the fixed explosive bolts, and the mounting platform is fixed on the conical surface of the circular conical tube at the lower end.
At this point, the gunpowder in the two connecting explosive bolts is actuated to disconnect the connecting explosive bolts, so that the annular devices are separated into two semicircular devices, and all the devices are fixedly restrained and contacted. The mounting platform is divided into two halves which are respectively connected with the crane through a lifting lug and a safety rope. The safety rope is gradually dropped underground by adjusting the length of the safety rope.
The high-altitude unmanned guide mounting platform of the single-column steel tube tower replaces the traditional manual operation, the mounting speed is high, and the safety is high. The guide adjusting device can quickly perform concentric and axial rotation adjustment on the conical steel pipe at the upper end, and mounting precision and speed are improved.
