Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, in particular to an auxiliary tooling for bridge docking. Background Art

[0002] With the continuous development of my country's economy, the importance of road construction has become increasingly prominent. It plays a vital role in promoting economic development, improving the quality of life of residents, improving traffic conditions, and promoting the urbanization process. It greatly shortens the travel time between different areas. In bridge construction, the bridge 7 needs to be transported to between the two piers 6 by a beam transporter, and then the prefabricated beam is lifted to a certain height by the crane's crane sling 8. The driver adjusts the position and angle of the prefabricated beam by operating the crane equipment until the assembly holes at the lower end of the bridge correspond to the steel bars at the top of the pier. Then, the prefabricated beam is slowly lowered by the lifting mechanism of the crane. Since the assembly holes on the prefabricated beam and the steel bars on the piers require high accuracy when assembling, The operator of this crane not only needs to have rich work experience, but also needs to have enough patience, because in the actual work process, the docking work between the bridge and the pier often requires repeated operation of the crane to adjust the docking angle. Since the prefabricated beams are heavy, the prefabricated beams are lifted to high altitudes by the crane for a long time. The long-term load of the lifting mechanism on the crane has a certain impact on the service life of the lifting motor. Moreover, when lifting the bridge, the crane spreader is easy to swing back and forth, and the adjustment remains unchanged. Its left and right swing is smaller, and it is easier to adjust the left and right position of the bridge. However, the bridge docking needs to be both fast and accurate, so as to improve work efficiency and reduce the accident rate. Therefore, the existing technology cannot meet the needs of rapid positioning, resulting in low efficiency and poor quality of bridge docking. Utility Model Content

The bottom end of the support leg 11 is equipped with a walking mechanism 12 that is easy to move. The walking mechanism 12 includes a walking wheel 13 and a walking motor (not shown in the drawings of the specification) installed at the lower end of the support leg 11. The power output shaft of the walking motor is transmission-connected to the walking wheel 13. When the walking motor is started, the walking motor drives the walking wheel 13 to rotate. A slewing mechanism 2 is provided at the top of the support platform 1, and a horizontally arranged front and rear displacement mechanism 3 is fixed at the top of the slewing mechanism 2. The front and rear displacement mechanism 3 can be rotatably assembled on the support platform 1 through the slewing mechanism 2. The slewing mechanism 2 includes a slewing support and a motor bracket 21 fixed at the top of the support platform 1. A slewing motor 22 is fixed on the motor bracket 21. The power output shaft of the slewing motor 22 is transmission-connected to the outer gear ring of the slewing support. When the slewing motor 22 is powered on and the slewing motor 22 is started, the slewing motor 22 drives the front and rear displacement mechanism 3 to rotate through the slewing support, which is convenient for adjusting the angle. The front and rear displacement mechanism 3 is equipped with support blocks 35 arranged at intervals. The front and rear displacement mechanism 3 includes a horizontally arranged slide rail 31. The two support blocks 35 are slidably connected to the slide rail 31. Support plates 32 are fixed at both ends of the slide rail 31. A horizontally arranged screw 33 is provided between the two support plates 32. Both ends of the screw 33 can be rotatably assembled on the support plates 32. A screw motor 34 is fixed on one of the support plates 32. The power output shaft of the screw motor 34 is transmission-connected to the screw 33. The upper end of the support block 35 is threadedly connected to the screw 33. The screw motor 34 is powered on and the screw motor 34 is started. The screw motor 34 drives the support block 35 to move in the front and rear directions along the slide rail through the screw 33. The two support blocks 35 move synchronously under the action of the front and rear displacement mechanism. The top ends of the two support blocks 35 are fixed with vertically arranged liftable legs 4. The liftable legs 4 include a vertically arranged support tube 41. The bottom end of the support tube 41 is fixed on the support block 35. The upper end of the support tube 41 is sleeved with a vertically arranged column 42. A first electric push rod 43 is provided in the support tube 41. The bottom end of the first electric push rod 43 is hinged to the bottom of the support tube 41, and the top end of the first electric push rod 43 is hinged to the bottom end of the column 42, and the top end of the column 42 is fixed to the outer support beam 51. The first electric push rod 43 is powered on and started. The first electric push rod 43 pushes the column 42 to move up and down in the vertical direction, which is convenient for adjusting the height of the top end of the column 42.A horizontally arranged outer support beam 51 is fixed to the top of the liftable leg 4. The outer support beam 51 is tubular and a second electric push rod 5 is fixed to the outer end of the outer support beam 51. The inner end of the outer support beam 51 is slidably sleeved with an inner support beam 52. A splint 53 is fixed to the inner end of the inner support beam 52. The other end of the inner support beam 52 is fixedly connected to the free end of the second electric push rod 5. The second electric push rod 5 is powered on and the second electric push rod 5 is started. The second electric push rod 5 pushes the inner support beam 52 to slide along the inner wall of the outer support beam 51, thereby pushing the splint 53 to move to the side of the bridge 7 to contact and tighten the bridge 7, which is convenient for the subsequent adjustment of the angle and position of the bridge 7 and the accurate docking of the bridge 7 with the pier 6.

[0014] Preferably, the clamping plate 53 is provided with an anti-skid protrusion 54 for preventing skidding.

[0015] Usage process:

[0016] When the present invention is in use, the traveling motor on the traveling mechanism 12 is first started, and the traveling motor drives the traveling wheel 13 to rotate, thereby moving the supporting platform 1 to the middle position of the two bridge piers 6, and then the bridge 7 is lifted from the beam transport vehicle by the crane sling 8, and the bridge 7 is moved to the top of the two bridges. After the left and right positions of the bridge 7 are adjusted by the crane, the first electric push rod 43 in the lifting leg 4 is started, and the first electric push rod 43 pushes the column to move upward, and then the rotary motor 22 is started to adjust the positions of the two splints 53 so that the bridge 7 is located just above the middle of the two splints 53, and then the first electric push rod 43 is started again, and the first electric push rod 43 pushes the column to continue to rise. Until the two splints 53 move up to both sides of the bridge 7, the two second electric push rods 5 are started respectively, and the two second electric push rods 5 push the inner support beam 52 toward the bridge 7 respectively until the splints 53 contact and press against the bridge 5, and then start the rotary motor 22 again. Under the action of the rotary motor 22, the bridge 7 is rotated to a certain angle so that the bridge 7 is located between the two piers 6, and the screw motor 34 is started. The screw motor 34 pushes the two support blocks 35 to move in the front and rear directions through the screw 33, and adjusts the front and rear position of the bridge 7. After the steel columns on the pier 6 are matched one by one with the assembly holes on the bridge 7, the bridge 7 is passed under the crane sling 8 until the bridge 7 is docked with the pier.
