The whole equipment is moved to the position to be installed of the steel structure upright post 63 by moving the traveling crane 1, so that the embedded foundation 61 with the embedded foundation bolts 62 is positioned in a rectangular notch of the traveling crane frame 11, and then a group of nuts positioned on the reinforcing base 631 are sequentially screwed and installed on all the foundation bolts 62; it should be considered that it is necessary to ensure that the steel structural uprights 63 are initially placed on the pallet mechanism 3, the nuts screwed onto the anchor bolts 62 before placing the steel structural uprights 63 are lower than the height of the lower end face of the reinforcing base 631 after placing the steel structural uprights 63 on the pallet mechanism 3, and the nuts should be screwed upward, so that the height of the set of nuts located below the reinforcing base 631 should be lower than the bottom end face of the final fixed height of the reinforcing base 631.

Then, the two track plates 2 are moved close to each other, so that the two track grooves 22 are in a combined state, the positioning rod 213 is in a movement locking state for the base plate 21, in addition, the insert block supporting plate 33 is in a complete insertion matching state with the slot supporting plate 32, then, the steel structure upright post 63 is lifted by the crane, so that the anchor bolts 62 pass through the bolt holes of the reinforcing base 631, and finally the reinforcing base 631 falls on the two insert block supporting plates 33, in order to ensure the safety of installation in the installation process, the steel structure upright post 63 can be obliquely supported in an auxiliary manner through an external supporting frame, or the auxiliary lifting state of the crane for the steel structure upright post 63 is always kept.

Subsequently, the fine adjustment of the height is performed while keeping the steel structure column 63 in the vertical state, the height of a set of nuts located under the reinforcing base 631 can be changed by screwing to change the mounting support height for the steel structure column 63, screwing of the nuts can be automatically performed by the two screwing actuating assemblies 53, specifically, the two swivel bases 41 are driven to rotationally move along the track grooves 22 by the U-shaped docking rod 42 so that the two screwing actuating assemblies 53 are located at the corresponding positions of the two nuts, then, the carry screws 5112 in the two screwing actuating assemblies 53 are sequentially rotated respectively, so that the vertical slide rails 511 are moved in the direction approaching the center of the track grooves 22, thereby clamping the nuts into the open spanners 535, then, the driving motor 531 is started to toggle the screwing swing arms 534 by the toggle arms 532, and when toggling, the follower pins 5341 will move along the rounded corner rectangular grooves 533, when the follower pin 5341 moves along the two horizontal grooves of the rounded rectangular groove 533, the turning swing arm 534 swings synchronously under the guiding restriction of the circular arc guide rail 522, and it is apparent that the directions of the follower pin 5341 moving along the two horizontal grooves of the rounded rectangular groove 533 are opposite, that is, the turning swing arm 534 swings reversely along the rotation direction of the circular arc guide rail 522, when the follower pin 5341 passes through the vertical groove from one of the horizontal grooves into the other horizontal groove, the slide supporting plate 521 rises or falls synchronously along the vertical slide rail 511, in this embodiment, when the nut under the reinforcing base 631 is automatically turned, when the follower pin 5341 moves along the upper horizontal groove of the rounded rectangular groove 533, the turning swing arm 534 swings to screw the nut through the open spanner 535, so that the nut moves up near the bottom end face of the reinforcing base 631, when moving from the upper horizontal section groove to the lower horizontal section groove through the vertical section groove, the open spanner 535 slides downwards along with the sliding supporting plate 521 and is separated from the nut, then the open spanner 535 swings along with the turning swing arm 534 in the direction of the lower horizontal section groove, the nut cannot be reversely turned back, the nut can be turned again when returning to the upper horizontal section groove, and thus the synchronous turning installation operation of the two nuts can be completed, and the U-shaped docking rod 42 needs to be held to timely adjust the heights of the two turning execution mechanisms 5 in the screwing installation process; after the installation of one set of nuts is completed, the screw actuator 5 is removed from under the reinforcement base 631 by rotating the carry screw 5112, and then the position of the screw actuator 5 is switched by rotation, and the above operation is repeated to complete the tightening operation of the remaining nuts.

Then, the automatic installation of the nut above the reinforcing base 631 is required, the installation screwing process of which is substantially identical to the operation of the nut below the reinforcing base 631, except that when the upper nut is installed, the open spanner 535 will automatically screw down the nut as the follower pin 5341 moves along the lower horizontal groove section of the rounded rectangular groove 533.

After the screwing installation of all nuts is completed in sequence, the inspection and confirmation can be performed manually, and after the confirmation is completed, the equipment can be withdrawn for the installation of the next steel structure column 63.

It should be noted that, in the process of switching and moving the two horizontal groove sections up and down along with the circular rectangular groove 533, the state of the screwed nut is not necessarily aligned with the opening of the open spanner 535, but the hexagonal nut is in a regular hexagonal structure, the maximum misalignment deviation between itself and the open spanner 535 is smaller, in addition, when the open spanner 535 is separated from the nut and is clamped with the nut again, the hexagonal nut is guided into from the chamfer of the upper end or the lower end of the open spanner 535, and a top contact is generated to the open spanner 535, so that the open spanner 535 is self-adaptively twisted and finely adjusted to meet the hexagonal nut in the open spanner 535, and therefore, the open spanner 535 and the nut form an automatic clamping connection during actual operation.

Furthermore, it should be noted that when the nut is screwed, the screwing locking direction can be changed by changing the steering direction of the driving motor 531, in addition, the device provided by the invention can replace manual work to complete most of nut installation operations, and considering that the bearing load of the driving motor 531 is larger when the nut is completely screwed, whether the reinforcing base 631 is locked by the nut which is distributed up and down finally can be performed by manual checking operation, namely the device provided by the invention only needs to screw the nut to a state close to locking.

The invention provides automatic installation equipment for building steel structure components, which can be matched with manual work to carry out locking auxiliary automatic installation of steel structure upright posts 63, and can synchronously install symmetrically distributed nuts through two oppositely arranged screwing execution mechanisms 5, so that the screwing efficiency of the nuts is improved, and meanwhile, the installation stability is improved; in addition, two screwing execution mechanisms 5 are assembled on the elastic lifting frame 4 capable of floating up-down adjustment, so that the adaptive adjustment of the nut installation moving height can be realized, and the switching movement of a plurality of groups of nut installation positions can be carried out through the rotary movement guide of the track grooves 22 capable of being combined and adjusted; thereby realizing automatic and rapid auxiliary installation of the steel structure upright post 63, solving the problems of inconvenient installation operation, large installation quantity, low installation efficiency, large energy consumption and the like in the existing manual installation and improving the installation convenience and the installation construction efficiency.
