Rectangular holes are opened on the support plates 11, and a pressure plate 21 is provided on the fixing plates 20. The pressure plate 21 has a T-shaped structure. The transverse section of the pressure plate 21 slides through the corresponding fixing plate 20 and the corresponding rectangular hole, and a compression spring 22 is installed between the longitudinal section of the pressure plate 21 and the corresponding fixing plate 20.

As shown in Figures 1, 3 and 6, a clamping portion 23 for clamping and fixing the prefabricated column is provided between the pressure plate 21 and the corresponding fixed plate 20, a pressure portion 24 for improving the docking accuracy of the prefabricated column is provided at the lower part of the support plate 11, a driving portion 25 for driving the fixed plate 20 to move up and down is provided on the fixed seat 10, and an execution portion 26 for driving the two support plates 11 to move toward each other is also provided on the fixed seat 10.

As shown in Figures 1, 3, 4 and 5, the driving part 25 includes a rectangular plate 250, and the upper end surface of the rear side of the fixed plate 20 is installed with a rectangular plate 250. The support plate 11 is provided with a No. 3 waist groove 251 at the corresponding position of the rectangular plate 250. A support shaft 252 is slidably installed between the two No. 3 waist grooves 251, and the support shaft 252 slides through the two rectangular plates 250. A No. 1 hydraulic cylinder 253 is installed on the front end surface of the transverse section of the fixed seat 10, and a connecting block 254 is fixedly installed between the telescopic section of the No. 1 hydraulic cylinder 253 and the support shaft 252.

During specific operation, the fixing seat 10 is installed on the lifting section of the external lifting device, and the external lifting device moves to the position of the prefabricated column, so that the support plate 11 is located on the left and right sides of the prefabricated column, and then the No. 1 hydraulic cylinder 253 pushes the support shaft 252 to move downward, and the support shaft 252 drives the corresponding fixing plate 20 to move downward through the rectangular plate 250, so that the pressure plate 21 moves to the position where the prefabricated column is required to be clamped, and then the execution part 26 drives the two support plates 11 to approach each other, so that the pressure plate 21 presses against the prefabricated column, and as the support plate 11 moves, the clamping part 23 clamps the prefabricated column to fix the prefabricated column, and then the No. 1 hydraulic cylinder 253 pulls the support shaft 252 upward, and the support shaft 252 drives the corresponding fixing plate 20 to move upward through the rectangular plate 250 to drive the fixed prefabricated column to move upward until the lower end surface of the prefabricated column is higher than the pressing part 24, and then the external lifting device moves the clamped prefabricated column to the corresponding steel bar position on the base, and drives the fixing mechanism 2 and the prefabricated column to move downward so that the pressing part 24 moves to a position close to the steel bar, and then the pressing part 24 presses the steel bar to align the lower part of the prefabricated column with the steel bar to ensure the accuracy of the prefabricated column inserted into the steel bar. After the assembly is completed, repeat the above operations and perform assembly processing of the prefabricated columns in sequence.

As shown in Figures 1, 3, 4 and 5, the clamping portion 23 includes a bearing seat 230, and the opposite surfaces of the two fixed plates 20 are slidably mounted with bearing seats 230 that are symmetrical front and back about the corresponding pressure plates 21.

The connecting rods 232 are rotatably connected to the corresponding clamping plates 231.

As shown in Figures 3 and 4, the bearing seat 230 is rotatably connected to the corresponding clamping plate 231 through a torsion spring rod, a roller shaft 233 is installed between the two upper and lower connecting rods 232, and a No. 1 waist groove 234 is opened on the clamping plate 231, and the roller shaft 233 slides through the corresponding No. 1 waist groove 234.

As shown in Figures 1, 4 and 5, the actuator 26 includes a guide rod 260, and a guide rod 260 and a bidirectional screw 261 are arranged between the two longitudinal sections of the fixed seat 10. The guide rod 260 slides through the two support plates 11, and the two support plates 11 are respectively threadedly connected with the two threaded sections of the bidirectional screw 261, and the two ends of the bidirectional screw 261 rotate to penetrate the fixed seat 10.

During specific operation, the external self-locking motor installed on the fixed seat 10 drives the bidirectional screw 261 to rotate, and the bidirectional screw 261 drives the two support plates 11 to approach each other, so that the pressure plate 21 presses against the prefabricated column. When the pressure plate 21 presses against the prefabricated column and cannot move further, the support plate 11 can compress the compression spring 22 and continue to move toward the prefabricated column. As the support plate 11 moves, the connecting rod 232 drives the clamping plate 231 to rotate and move toward the prefabricated column to clamp and fix the prefabricated column from the front and back directions.

When the external self-locking motor rotates in the opposite direction to drive the bidirectional screw 261 to drive the support plates 11 away from each other, the pressure plate 21 maintains pressure against the prefabricated column under the action of the compression spring 22 and remains stationary. As the support plate 11 moves, the connecting rod 232 will push the clamping plate 231 away from the prefabricated column. At the same time, under the action of the torsion spring rod, the clamping plate 231 will rotate to the side away from the prefabricated column to increase the distance between the two opposite clamping plates 231 on the left and right, thereby facilitating the horizontal movement of the fixing mechanism 2 to separate from the assembled prefabricated column.

As shown in Figures 1, 3, 5 and 6, the pressing portion 24 includes a support plate 240, and the left and right end surfaces of the support plate 11 are both slidably installed with support plates 240 up and down. The support plate 11 is symmetrically provided with two waist grooves 241 front and back, and shaft columns 242 are slidably installed in the two waist grooves 241. The two shaft columns 242 on the same support plate 11 slide through the corresponding support plates 240 at one end away from the relative support plate 11 and are jointly installed with a driving block 243. The driving block 243 is an isosceles trapezoidal structure, and a compression spring 244 is installed between the driving block 243 and the corresponding support plate 240. A pressing component is arranged on the side of the shaft column 242 away from the driving block 243, and a pushing member 3 for pushing the driving block 243 to move is arranged on the support plate 11.

As shown in Figures 5 and 6, the pressing assembly includes a support. Two shaft columns 242 on the same support plate 11 slide through the corresponding support plate 240 at one end away from the corresponding driving block 243 and are jointly installed with a support. Rollers 245 that come into contact with the steel bars are rotatably installed on the supports.

During specific operation, after the fixed prefabricated column moves to the corresponding steel bar position of the base, the pushing member 3 moves downward to squeeze the inclined surface of the driving block 243, so that the driving block 243 moves toward the prefabricated column, and the driving block 243 pushes the roller 245 to press against the steel bar through the shaft column 242 to ensure that the prefabricated column is accurately aligned with the steel bar during the subsequent descent process. Then the No. 1 hydraulic cylinder 253 pushes the support shaft 252 downward, and the support shaft 252 drives the corresponding fixed plate 20 to move downward through the rectangular plate 250, and the fixed plate 20 drives the clamped prefabricated column to move downward, so that part of the steel bar is inserted into the prefabricated column, and then the pushing member 3 moves upward away from the driving block 243, and the driving block 243 is in The compression spring 244 drives the roller 245 away from the steel bar and the prefabricated column, and then the pushing member 3 continues to move upward to drive the driving block 243, the shaft column 242 and the roller 245 to move upward synchronously to move to the range of squeezing the prefabricated column. Then, as the pushing member 3 moves upward, the pushing member 3 will squeeze the driving block 243, and the driving block 243 will push the roller 245 to press against the lower part of the prefabricated column through the shaft column 242, and cooperate with the clamping part 23, so that the subsequent insertion process of the prefabricated column can be carried out more smoothly and quickly, thereby improving the construction efficiency. Then the clamping part 23 continues to move downward, so that the steel bar is completely inserted into the prefabricated column, and at the same time, the lower end face of the prefabricated column fits with the base.

As shown in Figures 1, 2 and 5, the pushing member 3 includes a long plate 30, and the long plates 30 are slidably installed on the opposite surfaces of the two support plates 11, and the receiving plates 31 are slidably installed on the opposite sides of the two support plates 11. The receiving plates 31 are inverted L-shaped structure, and the lower end surface of the horizontal section of the receiving plate 31 and the lower end surface of the long plate 30 are symmetrically installed with shaft rods, and the shaft rods slide through the corresponding support plates 240, and reset springs 32 are installed between the lower end surface of the horizontal section of the receiving plate 31, the lower end surface of the long plate 30 and the corresponding support plate 240, and a connecting plate is fixedly installed between the long plate 30 and the corresponding receiving plate 31, a pushing assembly is arranged on the receiving plate 31, and a push-pull member 4 for driving the receiving plate 31 to move up and down is arranged on the fixed seat 10.

As shown in Figures 1, 2, 3 and 5, the push-pull member 4 includes a No. 2 hydraulic cylinder 40, and the No. 2 hydraulic cylinder 40 is fixedly installed on the front end face of the transverse section of the fixed seat 10. The telescopic section of the No. 2 hydraulic cylinder 40 is installed with a connecting plate 41, and the connecting plate 41 is a 匚-shaped structure. Push-pull rods 42 are installed on the lower end faces of the two longitudinal sections of the connecting plate 41, and a limit block 43 is provided on the sliding sleeve of the push-pull rod 42, and the limit block 43 is fixedly installed on the fixed seat 10, and the lower end of the push-pull rod 42 is slidably connected to the upper end face of the corresponding receiving plate 31 left and right.

As shown in Figures 5 and 6, the pushing assembly includes an extrusion block 33. The vertical section of the receiving plate 31 is close to the end face of the corresponding support plate 11 and is equipped with extrusion blocks 33 located on the upper and lower sides of the corresponding driving block 243. The end face of the extrusion block 33 that contacts the driving block 243 is an inclined surface.

During specific operation, the No. 2 hydraulic cylinder 40 pulls the connecting plate 41 to move downward, and the connecting plate 41 drives the push-pull rod 42 to move downward, and the push-pull rod 42 pushes the receiving plate 31 to move downward, and the long plate 30 moves downward synchronously with the receiving plate 31 through the connecting plate. As the receiving plate 31 moves downward, the extrusion block 33 located above contacts the upper inclined surface of the driving block 243, and pushes the driving block 243 to move toward the steel bar so that the roller 245 presses the steel bar. At this time, the reset spring 32 and the compression spring 244 are both compressed. After the steel bar is inserted into a part of the prefabricated column, the No. 2 hydraulic cylinder 40 pushes the connecting plate 41 to move upward, and the connecting plate 41 drives the receiving plate 31 to move upward through the push-pull rod 42, and the extrusion block 33 located above the receiving plate 31 moves away from the driving block 243. The driving block 243 is compressed by the spring Under the action of 22, the roller 245 is driven away from the steel bars and the prefabricated column. As the receiving plate 31 moves upward, the reset spring 32 is reset and then drives the support plate 240 to move upward. When the shaft column 242 contacts the inner wall of the upper end of the No. 2 waist groove 241, the shaft column 242 cannot move further, and the receiving plate 31 will stretch the reset spring 32 and continue to move upward. As the receiving plate 31 moves upward, the extrusion block 33 located below contacts the lower inclined surface of the driving block 243 to push the driving block 243 to move toward the prefabricated column, so that the roller 245 is pressed against the prefabricated column; after the prefabricated column is assembled, the roller 245, the clamping plate 231 and the pressing plate 21 are all away from the prefabricated column. At this time, the fixing mechanism 2 can be separated from the assembled prefabricated column to facilitate the subsequent assembly of the prefabricated column.
