Referring to fig. 1 and 2, the operator inserts the insertion rod into the insertion hole to position the holder 33. Then the operator passes the pulling rope 3 between the upper cylinder 12 and the support frame 1, and the pulling rope 3 passes through the top of the upper cylinder 12 from bottom to top along the upper cylinder 12. Then, the operator inserts the pulling rope 3 into the groove of the pulley 34, and the operator pulls the pulling rope 3 on the side opposite to the tilting direction of the support frame 1. At this time, the pull rope 3 generates a certain thrust to the end of the upper cylinder 12 far from the ground, so that the upper cylinder 12 is tightly abutted against the higher end of the lower cylinder 11, the balance of the force between the upper cylinder 12 and the lower cylinder 11 is improved, and the stability of the upper cylinder 12 is increased. The operator pulls the pull rope 3, and simultaneously, the pull rope 3 generates friction with the pulley 34, so that the pulley 34 generates rolling, and the pulley 34 can convert the friction between the pull rope 3 and the upper cylinder 12 into rolling friction, thereby reducing the friction force between the pull rope 3 and the upper cylinder 12 and saving the labor force of the operator. Meanwhile, the pulley 34 can reduce the abrasion of the pull rope 3 caused by the upper cylinder 12.

Referring to fig. 4, an operator rotates the screw 16, so that the first fixing block 14 approaches to the second fixing block 15, meanwhile, the screw 16 generates a certain pulling force on the upper barrel 12 through the first fixing block 14, the screw 16 pulls the upper barrel 12 to approach to the lower barrel 11 until the upper barrel 12 abuts against the higher end of the lower barrel 11, so as to improve the balance of the force between the upper barrel 12 and the lower barrel 11, thereby increasing the stability of the upper barrel 12, and further facilitating the operator to weld the upper barrel 12 to the lower barrel 11 quickly and conveniently. And a stress sheet 17 (as shown in fig. 1) is simultaneously bonded on the side wall of the upper cylinder 12 close to the lower cylinder 11, when an operator pulls the upper cylinder 12 to abut against the lower cylinder 11, the stress sheet 17 can measure the stress generated between the upper cylinder 12 and the lower cylinder 11, so that the operator can accurately adjust the balance of the force between the upper cylinder 12 and the lower cylinder 11.
Referring to fig. 4, the two positioning blocks 2 extend to one side of the inside of the upper cylinder 12 and the lower cylinder 11, and two opposite wall surfaces are respectively provided with a sliding groove 21, a sliding block 22 and a first spring 23 are arranged in the sliding groove 21, the sliding block 22 is slidably connected in the sliding groove 21, the first spring 23 is arranged between the sliding block 22 and the bottom wall of the sliding groove 21, and two ends of the first spring 23 are respectively and fixedly connected to the bottom walls of the sliding block 22 and the sliding groove 21.
Referring to fig. 4, when the operator inserts the positioning block 2 into the through hole 13, the operator first presses the slider 22 so that the slider 22 approaches the bottom wall of the slide groove 21. The slider 22 compresses the first spring 23, and the first spring 23 has an elastic restoring force when compressed. When the positioning block 2 passes through the through hole 13, the first spring 23 pushes a part of the slide block 22 to extend out of the slide slot 21 under the elastic restoring force of the first spring 23. At this time, the sliding block 22 limits the positioning block 2 through the sliding groove 21, so that the situation that the positioning block 2 is separated from the through hole 13 is reduced, and the matching stability of the positioning block 2 and the through hole 13 is improved.
Referring to fig. 5, the lower cylinder 11 has two reinforcing plates 5 slidably connected to the inner wall of the side close to the upper cylinder 12, and the two reinforcing plates 5 are respectively disposed on the sides of the two positioning bases 4 far away from the positioning beam opening 18. And a v-shaped frame 51 used for limiting the reinforcing plate 5 is welded on the lower barrel body 11, and the reinforcing plate 5 is connected between the v-shaped frame 51 and the lower barrel body 11 in a sliding manner. The reinforcing plate 5 is an arc-shaped plate, the reinforcing plate 5 and the lower barrel body 11 are coaxial, and two side walls of the reinforcing plate 5 along the length direction are respectively tightly attached to the inner walls of the 21274; the shaped frame 51 and the lower barrel body 11. Lower cylinder 11 deviates from at reinforcing plate 5, \ 21274, has seted up waist shape hole 52 on the lateral wall of shape frame 51 one side, and waist shape hole 52 is seted up along reinforcing plate 5's slip direction, and sliding connection has a push rod 53 that is used for promoting reinforcing plate 5 in waist shape hole 52, and push rod 53 threaded connection is on reinforcing plate 5 to the operator carries out the dismouting to push rod 53 fast convenient.
Referring to fig. 5, after the operator finishes positioning the upper cylinder 12, the operator pushes the push rod 53 to slide along the length direction of the waist-shaped hole 52, and at this time, the push rod 53 drives the reinforcing plate 5 to move towards the inside of the upper cylinder 12 until the reinforcing plate 5 abuts against the inner wall of the upper cylinder 12. And the v-21274-shaped frame 51 can limit the reinforcing plate 5, so that the reinforcing plate 5 is tightly pressed against the upper barrel 12, the reinforcing plate 5 limits the upper barrel 12 again, and the stability of the upper barrel 12 is further improved, so that an operator can weld the upper barrel 12 and the lower barrel 11 quickly.
The construction steps of the embodiment are as follows: the operator fixes lower barrel 11 earlier, and the operator overlaps from the height of supporting frame body 1 with last barrel 12 down, and last barrel 12 slides along the incline direction of supporting frame body 1, and it is inconsistent with lower barrel 11 to go up barrel 12. Then the operator hangs the pull rope 3 on the hook 31 through the safety buckle 32, and then inserts the support 33 on the upper cylinder 12. The operator then passes the pulling rope 3 between the upper cylinder 12 and the support frame 1, and passes the pulling rope 3 out of the upper opening of the upper cylinder 12, so that the pulling rope 3 is embedded in the groove of the pulley 34. Then, the operator pulls the pull rope 3, and the pull rope 3 generates a pushing force on the upper cylinder 12, so that the upper cylinder 12 abuts against the lower cylinder 11. The operator inserts the positioning seat 4 into the lower cylinder 11 and rotates the platen 42, so that the fixture block 44 is embedded into the fixture groove 43, thereby achieving the purpose of primarily positioning the upper cylinder 12.
An operator adjusts the distance between the first fixing block 14 and the second fixing block 15 according to the distance between the two through holes 13, then the operator respectively inserts the two positioning blocks 2 into the through holes 13, the operator rotates the screw 16, the screw 16 drives the upper cylinder 12 to approach the lower cylinder 11 through the first fixing block 14 until the upper cylinder 12 is in contact with the higher point of the lower cylinder 11, and at the moment, the operator judges the balance of the force between the upper cylinder 12 and the lower cylinder 11 according to the data generated by the stress sheet 17. After the operator has completely positioned the upper barrel 12, the upper barrel 12 is flush with the inner wall of the lower barrel 11, and then the operator pushes the push rod 53, so that the reinforcing plate 5 abuts against the inner wall of the upper barrel 12, the reinforcing plate 5 limits the upper barrel 12, and the stability of the upper barrel 12 is further improved. Then the operator welds the upper barrel 12 and the lower barrel 11, and finally the operator takes the pull rope 3, the pulley 34, the positioning seat 4, the push rod 53, the first fixing block 14 and the second fixing block 15 off the upper barrel 12 and the lower barrel 11 in sequence, so that the operator can pour concrete into the upper barrel 12 and the lower barrel 11.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
