A driving group is arranged below the bearing plate 5 and is used for driving the limiting rod 6 to slide in the left-right direction and driving the bearing plate 5 to rotate upwards.
As a further aspect of the invention, the first positioning pin 14 and the second positioning pin 19 are tapered.
As shown in fig. 1-3, 5-8, and 12;
Preliminary installation work:
after the steel column 2 is fully installed on the pier 1, the second positioning pin 19 on the first clamping rod 17 is firstly inserted into the bolt hole on the connecting piece 4 below, then the first clamping rod 17 and the second clamping rod 18 are fixed outside the steel column 2 through the fixing group, so that the first clamping rod 17 and the second clamping rod 18 can be firmly fixed, stable support is provided for subsequent installation, the center points of the second positioning pin 19, the inserting hole 20 and the connecting piece 4 are positioned on the same horizontal extension line, the first positioning pin 14 and the second positioning pin 19 are tapered, so that the insertion can be conveniently carried out, then the inserting rod 16 on the reinforcing rod 10 is inserted into the inserting hole 20, and the inserting rod 16 is matched with the inserting hole 20, so that the center points of the second positioning pin 19, the inserting hole 20, the inserting rod 16 and the connecting piece 4 are positioned on the same horizontal extension line, and the connecting piece 4 is parallel to the positioning plate 7;
The placement work of the support rod 3:
Then starting a driving group, wherein the driving group drives the rear end of the bearing plate 5 to rotate upwards (the size of the rotation angle is larger than the included angle between the top end of the supporting rod 3 and the pier 1 after the installation is completed as much as possible), the bearing plate 5 drives the reinforcing rod 10 and the inserting rod 16 to rotate upwards around the jack 20 and the center point of the bolt hole on the connecting sheet 4 when rotating upwards, the driving group can be stopped after the bearing plate 5 rotates for a certain angle, then the supporting rod 3 to be installed is lifted, the bottom end of the lifted supporting rod 3 is required to be placed into the two groups of limiting rods 6 on the left side and the right side of the bearing plate 5 when being placed towards the bearing plate 5, then the supporting rod 3 is slowly lowered, the two groups of limiting rods 6 are controlled to slide towards the middle through the driving group when the supporting rod 3 is lowered, and the limiting rods 3 are limited from the left side and the right side after the limiting rods 6 slide to the limiting positions, so that the supporting rod 3 can be in a parallel state with the bearing plate 5, and then the supporting rod 3 can be continuously lowered, but the lifting rope is ensured to be in a straight state all the time;
In the process of lowering the supporting rod 3, the supporting rod 3 slides towards the front of the supporting plate 5 along the supporting plate 5 under the limit of the limiting rod 6, two ends of the supporting rod 3 are in a sheet shape (as shown in fig. 2), the rear end of the positioning plate 7 is U-shaped, and the inner part of the U-shaped positioning plate 7 is the same as the end of the supporting rod 3, so when the supporting rod 3 slides for a certain distance, the supporting rod 3 contacts with the rear end of the positioning plate 7, and the orientation of the bolt hole of the supporting rod 3 is uncertain (the uncertainty of the direction means that the bolt hole on the connecting sheet 4 needs to be parallel when the supporting rod 3 is installed, and therefore the uncertainty means that whether the bolt hole on the connecting sheet 4 is parallel or not cannot be ensured), and two conditions exist after the contact:
firstly, the bolt holes are directly inserted into the U-shaped rear end of the positioning plate 7, and at the moment, the bolt holes of the supporting rod 3 are parallel to the bolt holes on the connecting sheet 4 and the positioning plate 7;
secondly, the bolt hole of the supporting rod 3 is in a state of being not parallel to the bolt hole on the connecting sheet 4 and the positioning plate 7;
When the support rod cannot be inserted into the positioning plate 7, the end part of the support rod 3 is blocked by the positioning plate 7 and cannot slide continuously, and the transmission group starts to work at the moment;
positioning and adjusting process of the support rod 3:
When the transmission group works, the positioning plate 7 is driven to rotate around the center point of the supporting rod 3 for one circle, the rear end of the U shape of the positioning plate 7 is continuously changed in the rotating process of the positioning plate 7, the positioning plate 7 is necessarily parallel to the supporting rod 3 in the rotating process, the rear end of the U shape is also positioned at a position capable of accommodating the supporting rod 3, when the positioning plate 7 is parallel to the end part of the supporting rod 3, the supporting rod 3 rapidly slides downwards along the bearing plate 5 under the action of gravity and is further directly inserted into the rear end of the positioning plate 7, the bolt hole of the supporting rod 3 can be determined to be parallel to the bolt hole on the connecting sheet 4 after the positioning plate 7 rotates for one circle, then the transmission group firstly drives the positioning plate 7 and the contact plate 9 to synchronously move downwards along the axis of the bearing plate 5 and the supporting rod 3 for a certain distance, before the distance movement is completed, the contact plate 9 will contact the first positioning pin 14 first, during the contact process, the first positioning pin 14 will be pushed to slide towards the inside of the sliding block 12 by the inclined side surface and compress the second spring 15, and during the process, the contact plate 9 and the positioning plate 7 are in the moving process, and the first positioning pin 14 is kept in contact with the contact plate 9, when the end of the first positioning pin 14 moves to the inclined surface 8 on the positioning plate 7 and contacts with the end of the supporting rod 3, the second spring 15 will have a tendency to relax elastically, when the bolt hole at the end of the supporting rod 3 moves to overlap with the first positioning pin 14, the second spring 15 will quickly stretch to enable the first positioning pin 14 to be inserted into the bolt hole on the supporting rod 3, then the transmission group will drive the contact plate 9 and the positioning plate 8 to rotate downwards, so as to separate the positioning plate 7 from the end of the supporting rod 3, then when the supporting rod 3 slides downwards along the bearing plate 5, the first positioning pin 14 and the sliding block 12 are driven to slide along the guide groove 11 towards the direction close to the connecting sheet 4, the first spring 13 is gradually stretched at the moment, and the center point of the first positioning pin 14 and the center point of the second positioning pin 19 are positioned at the same horizontal plane when the sliding block 12 slides to the forefront of the guide groove 11, so that the bolt hole on the supporting rod 3 is positioned at one side of the bolt hole on the connecting sheet 4 and is positioned at the horizontal height;
the support rod 3 and the connecting sheet 4 are fixed;
Because the rear end of the bearing plate 5 rotates upwards in the process of placing the supporting rod 3, the size of the rotation angle is larger than the included angle between the top end of the supporting rod 3 and the pier 1 after the installation is finished, the top end of the supporting rod 3 is positioned above the connecting sheet 4 positioned above and is not overlapped, but the bottom end of the supporting rod 3 is overlapped, the driving group is continuously driven at the moment to enable the bearing plate 5 to descend for a certain distance, the top end of the supporting rod 3 rotates from a clockwise angle to the direction of the connecting sheet 4 positioned above, and a person is required to ride on the steel column 2 or the cross beam positioned above, and the worker only needs to visually observe the position state of the bolt hole of the top end of the supporting rod 3 and the bolt hole of the connecting sheet 4, when the bolts can pass through the bolt holes at the top end of the supporting rod 3 and the bolt holes of the connecting sheet 4, the driving group can be stopped, at the moment, the upper end of the supporting rod 3 is fixed, the supporting rod 3 is also fixed in an inclined state, then the bolts inserted between the top end of the supporting rod 3 and the bolt holes of the connecting sheet 4 are screwed with nuts (pre-screwed, but not necessarily screwed), then the bearing plate 5 is controlled by the driving group to descend to a position where the limit rod 6 is lower than the supporting rod 3 and then stopped, the fixing group is released from fixing the first clamping rod 17 and the second clamping rod 18 on the steel column 2, the second positioning pin 19 is taken out from the bolt holes in the connecting sheet 4 below, and then the first clamping rod 17, the second clamping rod 18 and the inserting rod 16 are all moved out, so that the bolts can be screwed between the bottom end of the supporting rod 3 and the connecting sheet 4, and at the moment, the whole process is finished;
