AI Technical Summary
[0002]在吊车梁安装一般采取两种方式进行安装，第一种是采用钢丝绳和U型卡扣捆绑的方式，由于吊车梁卸车后处于平躺位置，高度方向的尺寸较大（吊车梁尺寸一般为长16.5m-54m*宽 0.4m-0.8m*高 1.5m-2.8m），穿钢丝绳比较困难，在起吊的过程中钢丝绳收紧时需要对钢丝绳长度进行调整，且在钢丝绳与吊车梁每个接触点都需要进行成品保护，花费大量的时间进行吊装准备工作，安装完成后进行钢丝绳拆卸时，钢丝绳抽出过程钢丝绳与卡扣与吊车梁摩擦碰撞会导致成品构件表面油漆受损，增加后续补漆工作；第二种是采用钢板钳或者钢板夹钩进行吊装，钢板钳或钢板夹钩自带锯齿形夹口，通过重物拉紧钳口自行夹紧，这种方式有两大弊端，一是吊车梁重量比较大，钢板钳会在吊车梁上留下较深的压痕，后期需要进行修复处理，二是钢板钳是通过重物自重进行夹紧，在吊车梁吊至安装位置时，重物对钳口的拉紧力减小，可能会出现夹紧力不足，突然松钩或者出现吊点滑动的情况，施工安全性无法保证
[0012] The beneficial effects of this utility model are as follows: After connection and fixation using a locking mechanism, installation can proceed.

Furthermore, this clamp is lightweight, allowing for operation by a single person, thus improving operational flexibility. Simultaneously, the lifting device is equipped with multiple rows of first locking holes, which can be adjusted according to the width of the crane beam flange, increasing the versatility of the lifting device. It is convenient to use, greatly improving labor efficiency and accelerating on-site construction progress while ensuring construction safety.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting construction technology in steel structure industrial plants, specifically to a hoisting tool for installing crane beams. Background Technology
[0002] There are generally two methods for installing crane beams. The first method uses wire ropes and U-shaped clips for binding. Because the crane beam lies flat after unloading, its height dimensions are relatively large (typically 16.5m-54m long * 0.4m-0.8m wide * 1.5m-2.8m high), making wire rope threading difficult. During lifting, the wire rope length needs to be adjusted when tightening, and each contact point between the wire rope and the crane beam requires protection. This involves a significant amount of time spent on preparation. After installation, when disassembling the wire rope, the process of pulling the wire rope out of the clips... Friction and collision between the clamp and the crane beam can damage the paint on the surface of the finished component, increasing the need for subsequent touch-up painting. The second method is to use plate clamps or plate hooks for hoisting. Plate clamps or plate hooks have serrated jaws and tighten themselves by pulling the weight. This method has two major drawbacks: first, the crane beam is quite heavy, and the plate clamps will leave deep indentations on the crane beam, requiring later repair; second, since the plate clamps rely on the weight of the load for clamping, the tension on the jaws decreases when the crane beam is hoisted to the installation position, which may result in insufficient clamping force, sudden loosening of the hook, or slippage of the lifting point, compromising construction safety.
[0003] Therefore, a lifting device for crane beam installation is provided to increase the speed of crane beam installation and improve the safety of the lifting process. Summary of the Invention
[0004] The purpose of this invention is to provide a lifting device for crane beam installation that increases the speed of crane beam installation and improves the safety of the lifting process.

The hook mechanism includes an L-shaped locking plate fixedly connected to the upper surface and left side of the connecting plate, and a base plate located below the L-shaped locking plate and below the connecting plate and connected by a connecting assembly. The distance between the base plate and the connecting plate is adjusted by the connecting assembly.

Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1
[0015] like Figures 1 to 4 As shown, a lifting device for crane beam installation includes a connecting plate 1, a locking mechanism located on the right side of the connecting plate 1 for fixing to the crane beam 7, several hook mechanisms 2 located on the left side of the connecting plate 1 for positioning the connecting plate 1 with the flange plate of the crane beam 6, and lifting lugs 4 located on the upper surface of the connecting plate 1. The lifting lugs are welded and fixed to the upper surface of the connecting plate 1, and the lifting lugs 4 are made of 20mm thick steel plates. The hook mechanism 2 includes an L-shaped clamping plate 21 that is fixedly connected to the upper surface and left side of the connecting plate 1 by welding, and a base plate 23 located below the L-shaped clamping plate 21 and below the connecting plate 1 and connected by a connecting assembly 22. The distance between the base plate 23 and the connecting plate 1 is adjusted by the connecting assembly 22 to accommodate different thicknesses of the flange plate of the crane beam, thus having a wide range of applications. At the same time, it avoids the phenomenon that the distance between the connecting plate 1 and the base plate 23 is too small to be clamped to the flange plate of the crane beam, that is, there is no need to replace the hook mechanism 2. Three hook mechanisms 2 are provided, evenly distributed along the front and rear direction of the connecting plate 1, ensuring uniform force distribution on the crane beam 6. Two connecting components are provided, located on the front and rear sides of the L-shaped clamping plate 21, ensuring a firm connection between the L-shaped clamping plate 21 and the base plate 23, resulting in good fixation. This utility model allows for installation after connection and fixation using a locking mechanism. After installation, the locking mechanism is released for disassembly. This clamp is lightweight, allowing for operation by a single person, improving operational flexibility. Multiple rows of first locking holes are provided on the lifting device, allowing adjustment based on the width of the crane beam flange, increasing the device's versatility. It is convenient to use, greatly improving labor efficiency and accelerating on-site construction progress while ensuring construction safety. The hook mechanism can be adjusted according to different crane beam models to accommodate varying flange thicknesses, ensuring wide applicability and preventing situations where small hook mechanisms cannot be properly engaged with the crane beam flange.

The distance between the lower surface of the connecting plate 1 and the upper surface of the base plate 23 is adjusted according to the thickness of the flange of the crane beam 6, so that the distance between the lower surface of the connecting plate 1 and the upper surface of the base plate 23 is greater than the thickness of the flange of the crane beam 6. This facilitates the connecting plate being secured to the flange of the crane beam 6, achieving initial positioning of the flange of the crane beam 6 and the connecting plate. Then, the connecting plate and the flange of the crane beam 6 are locked together by a locking mechanism. The operation is simple and the fixing is secure.
[0017] The locking mechanism includes a plurality of first locking holes 3 located on the right side of the connecting plate 1, a plurality of second locking holes located on the flange plate of the crane beam 6 and cooperating with the first locking holes 3, and a locking bolt assembly 7 passing through the first locking holes 6 and the second locking holes. The first locking holes 3 are arranged in at least two rows, with at least two rows of first locking holes 3 evenly distributed from left to right along the connecting plate 1, and one row of first locking holes 3 evenly arranged from front to back. This arrangement of multiple rows of first locking holes 3 allows for adjustment based on the width of the crane beam flange plate, increasing the versatility of the lifting device. The first locking holes 3 are the same size as the second locking holes on the crane beam, with a diameter of Φ22mm and a spacing of 100mm. The first locking holes 3 are arranged in three rows.
[0018] This device can utilize on-site steel plates, requiring only simple on-site processing. It is also lightweight, easy to use, flexible, and highly safe.
[0019] During installation, adjust the distance between the connecting plate 1 and the base plate 23 of the flange plate of the crane beam 6 according to the thickness of the flange plate. At the lifting point position (determined according to the length of the wire rope and the position of the center of gravity of the object being lifted), install the three hook mechanisms 2 into the upper flange plate of the crane beam 6. Adjust the position of the first locking hole 3 to correspond with the second locking hole on the crane beam (the adjustment position should be such that the contact length between the hook and the upper flange plate of the crane beam is not less than 100mm). Insert the locking bolt assembly 7 (M20 high-strength bolt) into the corresponding first locking hole 3 and second locking hole, and tighten it to complete the installation of the lifting device.
