[0002] Expressways are currently fast channels for transportation between different regions. They are also an important part of the expressway network that strengthens the radiation of cities to surrounding areas. They play a very important role in accelerating the coordinated development of urban agglomerations. When expressways pass through rivers and valleys, bridges need to be built. In order to increase the speed of construction, prefabricated and assembled components will be used in large quantities. The cylindrical piers in the bridges are the main supporting components of the bridges. Their quality and production efficiency directly affect the construction rate of the road.

[0003] As prefabricated and assembled components, cylindrical piers are usually manufactured in a prefabrication plant and then transported to the site for assembly. According to the size of the cylindrical pier, a suitable steel mold is selected, and the welded and tied steel cage is fixed to the inside of the steel mold. The steel mold is lifted by a crane and kept in a vertical state. The steel mold is fixed to the prefabricated pier column base and fixed with bolts. Cement is injected into the steel mold using a cement pump and vibrated to compact it. After the cylindrical pier solidifies and dries, the steel mold is lifted and lowered by a crane, and the steel mold is removed. The cylindrical pier is then transported to the site for assembly.

A support seat 14 is installed on the top surface of each group of the mounting grooves 13, and a T-shaped screw 15 is slidably installed inside the mounting groove 13. The T-shaped screw 15 slides through the end of the support seat 14, and a locking nut 16 is installed on the top outer ring thread of the T-shaped screw 15. The top concave surface of the support seat 14 slides with the outer wall of the steel mold 7. Rope hooks 17 are fixed on both sides of the two ends of the support seat 14, and a binding strap 18 is bolted between the rope hooks 17 on both sides. The outer wall of the binding strap 18 slides with the outer wall of the steel mold 7.

[0035] like Figure 3 、 Figure 5 and Figure 6As shown, a card seat 19 is fixedly connected to one side of the top surface of the bracket 6 close to the base 1, and the card seat 19 is concave. A round hole square plate 20 is fixedly connected to one end of the steel mold 7 close to the base 1. The inner circle of the round hole square plate 20 coincides with the inner circle of the steel mold 7. An insert 21 is fixedly connected to the bottom surface of the round hole square plate 20. The inner walls of the card seat 19 on both sides of the insert 21 slide together. A plurality of connecting holes 22 are provided in the middle of the card seat 19 and the middle of the insert 21. A pin rod 23 is slidably installed inside the connecting hole 22. A plurality of forming square platforms 24 are fixedly connected to both sides of the top surface of the base 1. The forming square platforms 24 have the same shape and size as the round hole square plate 20, and the forming square platforms 24 correspond to the round hole square plate 20. When working, the steel mold 7 is placed on the support seat 1 4, the top concave surface is formed, so that the insert 21 is inserted into the middle of the card seat 19, so that the connecting hole 22 on the insert 21 is connected with the connecting hole 22 on the card seat 19, and the pin rod 23 is inserted through the connecting hole 22 to fix the insert 21 to the card seat 19, and further fix the steel mold 7. When the bracket 6 drives the steel mold 7 to rotate and stand up, the weight of the steel mold 7 acts on the card seat 19 through the round hole square plate 20 and the insert 21, supporting the steel mold 7 and preventing the steel mold 7 from sliding downward, thereby reducing the probability of the steel mold 7 slipping during the rotation and standing process; by overlapping the forming square platform 24 with the round hole square plate 20, it is convenient for the staff to reasonably control the position of the steel mold 7 on the top surface of the base 1, and at the same time, it is convenient for the staff to fix the steel mold 7 to the base 1.

[0036] like Figures 1 to 2 As shown, multiple groups of long screws 25 are fixed on both sides of the top surface of the base 1, and the multiple groups of long screws 25 are located on both sides of the forming square platform 24.

The bottom surface of the pressure plate 26 slides with the top surface of the round hole square plate 20, and a nut is threadedly installed on the top outer ring of the long screw 25; when working, the bracket 6 erects the steel mold 7 vertically, so that the round hole square plate 20 coincides with the forming square platform 24, and the pressure plate 26 is slidably installed on the outer ring of the long screw 25, so that the long end of the pressure plate 26 is rotated to the top surface of the round hole square plate 20, and the pressure plate 26 is locked and fixed with a nut to fix the steel mold 7.

[0037] like Figures 1 to 2As shown, the lower end of the steel wire rope of the traveling crane 3 is fixedly connected to a hanging beam 27, and both ends of the hanging beam 27 are fixedly connected to hooks 28.

When the traveling crane 3 lifts the bracket 6 for rotation, the hanging beam 27 is used to keep the bracket 6 horizontal for rotation, thereby improving the stability of the bracket 6 during rotation and reducing the probability of danger caused by uneven force and deviation of the bracket 6.

[0043] Working principle: Insert the T-shaped screw 15 into the interior of the installation groove 13 so that the threaded end of the T-shaped screw 15 is vertically upward, place the support base 14 on the top surface of the bracket 6 so that the top end of the T-shaped screw 15 passes through the two ends of the support base 14, use the locking nut 16 to thread the top end of the T-shaped screw 15, and tighten the locking nut 16 to fix and lock the support base 14;

[0044] The motor 10 drives the spur gear 11 to rotate, and through the transmission of the synchronous belt 12, drives multiple spur gears 11 to rotate synchronously, driving the main action wheel 9 to rotate.

[0046] The hooks 28 at both ends of the hanging beam 27 are hung on the hanging ears 29 on both sides of the bracket 6. The driving crane 3 pulls the bracket 6 so that the bracket 6 rotates along the guide rod 5 and rotates the bracket 6 to a vertical state. At this time, the square plate 20 with a round hole overlaps with the forming square platform 24. The pressing plate 26 is slidably installed on the outer ring of the long screw 25 so that the long end of the pressing plate 26 rotates to the top surface of the square plate 20 with a round hole.

[0047] Remove the strap 18 and the pin rod 23 to separate the steel mold 7 from the bracket 6. The crane 3 lowers the bracket 6. The auxiliary action wheel 31 contacts the side wall of the base 1, driving the mounting frame 30 to move to one side of the bracket 8, pushing the slider 33 to slide along the shock-absorbing groove 32, squeezing the damping shock absorber 34. The shock absorption and buffering of the damping shock absorber 34 reduces the impact force of the bracket 6 when it falls, so that the main action wheel 9 is in contact with the ground; then move the bracket 6 to the next forming square platform 24 position to carry out the prefabrication work of the new cylindrical pier.
