Description

Technical Field

[0001] This invention relates to the field of precast beam transportation equipment technology, specifically a precast beam transportation and orientation platform. Background Technology

[0002] Before hoisting the precast box girder, two guide vehicles are needed to secure both ends of the precast girder before transporting it to the designated location for hoisting. During transportation, due to various factors such as the site conditions, there is a need for the guide vehicles to turn (usually within 90 degrees). Because the precast girder is quite long (usually between 20 and 40 meters), the clamping mechanism at the end of the precast girder on the guide vehicle is connected to the guide vehicle body in a movable manner to facilitate turning. However, the following problem arises during turning: when the front and rear guide vehicles turn to the right or left simultaneously, the angle of the precast girder does not change as the guide vehicle angle adjusts. Therefore, the guide vehicle cannot properly handle the precast girder. The center of gravity at the ends of the beam changes, causing the center of gravity of the precast beam to tilt. The center of gravity at the front end of the precast beam will tilt in the opposite direction of the steering of the front guide vehicle, while the center of gravity at the rear end of the precast beam will tilt in the same direction as the steering of the rear guide vehicle. This causes instability in the center of gravity of the precast beam during the steering of the guide vehicle. In severe cases, the guide vehicle and the precast beam may even overturn, endangering the lives of construction workers. There is a lack of equipment that can simultaneously stabilize the center of gravity of the front and rear ends of the precast beam in real time according to the steering direction of the front and rear guide vehicles when the precast beam is controlled by the guide vehicle, so as to ensure that the precast beam remains stable during transportation and steering and avoid the overturning of the guide vehicle.

[0048] The method of use and advantages of this invention: The working process of this precast beam transportation and orientation platform is as follows:

[0049] like Figures 1 to 21 As shown, when this device is in use, the front and rear ends of the precast beam are first placed between the two clamping frames 3 by the equipment. Then, the first electric push rod 42 and the second electric push rod 43 are activated to drive several first locking sleeves 44 and second locking sleeves 45 to stop the front and rear ends of the precast beam respectively, thereby realizing the locking of the front and rear ends of the precast beam. Under the pressure of the weight of the precast beam, the clamping frame 3 and the fixed shaft 41 will not rotate due to the turning of the front guide car 1 or the rear guide car 2. The clamping frame 3 and the fixed shaft 41 are always in a static and fixed state.

[0050] During the transportation of precast beams, when it is necessary to control the steering of the precast beams, taking a right turn as an example, both the front guide vehicle 1 and the right guide vehicle need to turn to the right. During the turning process, the left front end of the precast beam will lose some support, and the right rear end of the precast beam will lose some support, causing the precast beam to become unstable. At this time, first observe the operation of the steering stabilization device 5 on the front guide vehicle 1. As the front guide vehicle 1 turns to the right, the first gear 532 and the second gear 53 in the drive assembly 53 inside the front guide vehicle 1... 3. The entire assembly deflects at a certain angle around the fixed shaft 41. During the deflection process, the second gear 533 does not mesh with the sector gear, while the first gear 532 meshes with the sector gear 531. This drives the deflection assembly 54 and the extension lifting assembly 55 located on the left side of the front guide vehicle 1 to operate automatically. First, the deflection assembly 54 is driven to rotate clockwise as the first gear 532 revolves around the sector gear 531. This rotation of the first gear 532 causes the deflection frame 540, which meshes with it, to move closer to the fixed shaft 4. The sliding motion causes the hinge frame 541 to slide away from the first deflecting rod 544 and the second deflecting rod 545. Then, with the cooperation of the first connecting rod 542 and the second connecting rod 543, the first deflecting rod 544 and the second deflecting rod 545 simultaneously deflect towards the hinge frame 541 around their meshing point. Subsequently, under the transmission of the pulley 548 and the drive belt 549, the two support arms 551 connected to the first shaft 546 and the second shaft 547 respectively deflect around the first shaft 546 and the second shaft 547. 547 deflects synchronously away from the opposite side, and the deflection angle is proportional to the turning angle of the front guide vehicle 1. As the front guide vehicle 1 turns, the contact range between the two support arms 551 and the bottom of the precast beam is gradually increased, thereby avoiding instability of the precast beam's center of gravity to a certain extent. When the front guide vehicle 1 turns to the left, the second gear 533 meshes and rotates with the sector gear 531, causing the deflection component 54 located on the right side of the front guide vehicle 1 to operate automatically, thereby adjusting the center of gravity on the right side of the precast beam.

[0051] As the two support arms 551 deflect synchronously away from each other, the protrusion at the bottom of the support block 552 slides synchronously in the arc-shaped groove 554 on the extension plate 553. This causes the support block 552 to slide away from the fixed axis 41 on the support arm 551 during the deflection process, thereby extending the length of the support arm 551 and further increasing its support range. While increasing the support range, the precast beam's center of gravity shifts, causing it to tilt towards the side with the missing center of gravity, causes the mounting bracket 555 to slide synchronously as the support block 552 slides. This, in turn, causes the third gear 560 to rotate, which in turn causes the first bevel gear 558, which meshes with it, to rotate at a certain angle. This, in turn, causes the drive screw 556 to rotate, causing the drive block 557 to slide on top of the mounting bracket 555. This, in turn, causes the two third connecting rods to... The deflection of rod 563 causes the lifting plate 562 to rotate upwards around the rotational connection point with the rotating frame 561. The longer the travel of the support block 552, the greater the deflection angle of the lifting plate 562. The first support sleeve 565 contacts the bottom of the precast beam, and the first spring 564 contracts, thus lifting the bottom of the precast beam upwards. This suppresses the tendency of the precast beam to tilt to one side, thereby further realizing the real-time adjustment of the center of gravity of the lower part of the precast beam according to the center of gravity offset state and providing an upward supporting force to prevent it from overturning. During the movement of the first support sleeve 565, several sliding wheels on the surface of the first support sleeve 565 can effectively reduce the friction between the first support sleeve 565 and the precast beam, so as to assist the first support sleeve 565 in smoothly adjusting the center of gravity and supporting the precast beam.

[0052] As the two support arms 551 rotate synchronously to increase the support range, the first gear 532 rotates synchronously, driving the fourth gear 571 to rotate synchronously. This causes the sliding frame 572, which meshes with it, to slide away from the fixed shaft 41, thereby driving the connecting rod 573 to slide towards the L-shaped sliding frame 574. This causes the horizontal slider 578 to slide towards the vertical slider 575, thereby driving the vertical slider 575 to slide upward. This causes the second support sleeve 577 to slide upward at the side end of the clamping frame 3, and the second spring 576 to contract synchronously. This suppresses the tendency of the upper part of the precast beam to tilt to the side. In combination with the first support sleeve 565, the center of gravity of the upper and lower ends of the precast beam can be adjusted in real time according to the center of gravity offset of the precast beam to avoid the tendency of it to overturn.

[0053] Since the sector gear 531 in the steering stabilization device 5 on the rear guide vehicle 2 is symmetrically arranged with the sector gear 531 in the steering stabilization device 5 on the front guide vehicle 1, when the rear guide vehicle 2 turns right, the sector gear 531 in the steering stabilization device 5 on the rear guide vehicle 2 will mesh with the second gear 533. This causes the deflection component 54 and the extension lifting component 55, which are automatically operated on the front guide vehicle 1 and the rear guide vehicle 2 to be on different sides. This adapts to the different directions of the center of gravity offset at the front and rear ends of the precast beam during the turn, thereby ensuring that the precast beam is always in a relatively stable and balanced state during the turn.
