技术领域technical field
本发明属于钢筋笼起吊装置领域,更具体地说,涉及一种钢筋笼对接调整装置。The invention belongs to the field of steel cage lifting devices, and more specifically relates to a steel cage butt joint adjustment device.
背景技术Background technique
目前,由于部分工程桩过长而不能通过一次吊装完成整个桩的钢筋笼吊装,从而采用分段吊装。分段吊装两节钢筋笼之间的连接方式一般采用焊接或其他固接方式,而通过焊接方式连接所花费的时间太长从而容易造成塌孔、断桩现象,进而影响工程质量造成重大安全隐患,所以宜采用机械连接。但是机械连接需要有钢筋笼起吊装置相配合,例如中国专利号为201120172116.5,公开日为2012年2月22日,公开的一种钢筋笼起吊装置的专利文件,该发明提供一种结构简单,使用方便,能够对钢筋笼整体吊装,且吊装过程中稳定性好,方便装入桩孔的钢筋笼起吊装置。包括有一根平衡梁,平衡梁设置于于钢筋笼上方中间,其方向与钢筋笼轴线方向平行,平衡梁的下表面两端对称设置有两组固定钢丝绳,并分别将每组固定钢丝绳的两端对称固定在钢筋笼的轴向两端的两边,在平衡梁的中间正上方,还设置有滑轮,滑轮上穿过有活动钢丝绳,并将活动钢丝绳的两端对称固定在平衡梁的上表面。该发明结构简单,使用方便,能够对钢筋笼整体吊装,且吊装过程中稳定性好,可以方便的将钢筋笼吊放到桩孔中。At present, because some engineering piles are too long to complete the steel cage hoisting of the whole pile by one hoisting, segmental hoisting is adopted. Welding or other fastening methods are generally used for the connection between the two sections of steel cages in segmental hoisting, but the time spent on the connection by welding is too long, which may easily cause collapsed holes and broken piles, which will affect the quality of the project and cause major safety hazards , so a mechanical connection should be used. However, the mechanical connection needs to be matched with a steel cage lifting device. For example, the Chinese patent number is 201120172116.5, and the disclosure date is February 22, 2012. The disclosed patent document of a steel cage lifting device provides a simple structure, easy to use It is convenient to hoist the steel cage as a whole, and has good stability during the hoisting process, and it is convenient to install the steel cage hoisting device into the pile hole. It includes a balance beam. The balance beam is set in the middle of the upper part of the reinforcement cage, and its direction is parallel to the direction of the axis of the reinforcement cage. Two sets of fixed steel wire ropes are arranged symmetrically on both ends of the lower surface of the balance beam, and the two ends of each set of fixed steel wire ropes are respectively It is symmetrically fixed on both sides of the axial two ends of the reinforcement cage, and a pulley is also arranged directly above the middle of the balance beam, and a movable wire rope passes through the pulley, and the two ends of the movable wire rope are symmetrically fixed on the upper surface of the balance beam. The invention is simple in structure, easy to use, capable of hoisting the reinforcement cage as a whole, and has good stability during the hoisting process, and can conveniently hoist the reinforcement cage into the pile hole.
又如,中国专利号为201220066562.2,公开日为2012年11月7日,公开的一种起吊钢筋笼的吊具结构的专利文件,该发明涉及一种起吊钢筋笼的吊具结构,包括吊机上的主钩、扁担梁、吊索,扁担梁两端分别设置一个滑轮,每个滑轮上绕有吊索,吊索的两端通过扣件分别扣住钢筋笼上下两端,形成二个吊点;扁担梁上端设有V字形吊钩。该发明能够用一台吊机就能把钢筋笼吊放到桩孔内,使钢筋笼起吊后不变形,且结构简单,容易实现。As another example, the Chinese patent number is 201220066562.2, and the publication date is November 7, 2012. It discloses a patent document for a sling structure for lifting a steel cage. The invention relates to a sling structure for lifting a steel cage, including The main hook, the pole beam, and the sling, and a pulley is set at both ends of the pole beam, and a sling is wound around each pulley, and the two ends of the sling are fastened to the upper and lower ends of the steel cage by fasteners to form two lifting points. ; The upper end of the pole beam is provided with a V-shaped hook. The invention can use a crane to hoist the reinforcement cage into the pile hole, so that the reinforcement cage does not deform after hoisting, and has a simple structure and is easy to realize.
但是以上的两份文献所公开的钢筋笼起吊装置在对钢筋笼起吊操作过程中存在不易控制两节钢筋笼端面平行而保证每根钢筋完全对接的问题,而且吊起时钢筋笼会摆动,不易调整,吊装时需要多个工人配合,费时费力,安装成本高。However, the reinforcement cage lifting device disclosed in the above two documents has the problem that it is difficult to control the parallelism of the end faces of the two reinforcement cages to ensure that each reinforcement cage is completely connected to each other during the lifting operation of the reinforcement cage, and the reinforcement cage will swing during lifting, which is not easy Adjustment and hoisting require the cooperation of multiple workers, which is time-consuming and labor-intensive, and the installation cost is high.
