Description

Technical Field

[0001] The utility model belongs to the technical field of high-speed railway bridge construction tooling, and particularly relates to a hoisting device suitable for various high-speed railway box girders. Background Art

[0002] When it is necessary to erect post-tensioned prestressed concrete simply supported beams, there are usually multiple beam types in a beam yard, and the hoisting positions of each beam type are different. Therefore, it is necessary to frequently replace the gantry crane's hoisting equipment to complete the construction work. Frequent replacement of hoists has always been a problem that has troubled on-site construction personnel and technicians. Usually, the method of replacing different hoists with different beam types is adopted, that is, after the hoisting of a box beam of one beam type is completed, when another beam type needs to be hoisted, it is necessary to replace the matching hoisting equipment. Obviously, this method is cumbersome to operate. Although it can complete the hoisting operations of different beam types, it has a huge workload and wastes a lot of time. The overall cost is high and the operation is inconvenient, dangerous, time-consuming and labor-intensive. Summary of the invention

[0003] In order to solve the above problems, the purpose of the utility model is to provide a hanger device suitable for various high-speed railway box girders.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a lifting device suitable for a variety of high-speed railway box girders, including a main box body and multiple lifting rings; wherein the main box body is a rectangular box body structure, with a large elliptical hole formed at each of the four corners, a small elliptical hole formed at each of the two long sides, and multiple lifting rings extending along the length direction of the main box body installed side by side in the middle of the two short sides.

[0005] The main box is welded with Q355B steel and has dimensions of 4480 mm long * 1450 mm wide * 450 mm high.

[0006] The major axis of the large elliptical hole is 150 mm.

[0007] The major axis of the small elliptical hole is 120 mm.

[0008] The number of the lifting rings is 6.

[0009] The utility model provides a hanger device suitable for various high-speed railway box girders, which has the following beneficial effects:

[0010] 1) Applicable to construction sites with various beam types. 2) Reduces the inconvenience of frequently changing the lifting equipment of different beam types and other troubles to the staff. 3) Improves work efficiency and accuracy, and is easy to operate. 4) Reduces costs. It solves the various shortcomings of traditional lifting methods for different beam types, the numerous tools, and the time-consuming and labor-intensive process. It not only simplifies the lifting of different beam types of high-speed railway box girders, but also greatly saves labor costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 3 The utility model provides a side view of a hanger device suitable for various high-speed railway box girders. DETAILED DESCRIPTION

[0014] The following is a detailed description of the hanger device applicable to various high-speed railway box girders provided by the utility model in conjunction with the accompanying drawings and specific implementations.

[0015] like Figures 1 to 3 As shown, the lifting device provided by the utility model and suitable for various high-speed railway box girders includes a main box body 1 and a plurality of lifting rings 2; wherein, the main box body 1 is a rectangular box body structure, with a large elliptical hole 3 formed at each of the four corners, a small elliptical hole 4 formed at each of the two sides of the two long sides, and a plurality of lifting rings 2 extending along the length direction of the main box body 1 are installed side by side in the middle of the two short sides.

[0016] The main box body 1 is welded with Q355B steel and has a size of 4480 mm long*1450 mm wide*450 mm high.

[0017] The major axis of the large elliptical hole 3 is 150 mm.

[0018] The major axis of the small elliptical hole 4 is 120 mm.

[0019] The number of the lifting rings 2 is 6.

[0020] The method for using the lifting device provided by the utility model and suitable for a variety of high-speed railway box girders is now explained as follows: when lifting a high-speed railway box girder, the operator first places a lifting device on the top surfaces of both ends of the high-speed railway box girder to be lifted, and then connects the lifting device on the gantry crane with the lifting ring 2 on the lifting device with a pin shaft, and ensures that the connection is firm. Then, according to the size of the high-speed railway box girder, a lifting rod is symmetrically inserted downward at the corresponding positions in the four large elliptical holes 3 or the four small elliptical holes 4, and then the lifting mechanism of the gantry crane is used to lift the lifting device. At this time, the lower end of the lifting rod will be exposed under the bottom surface of the main box body 1, and then the lower end of the lifting rod is passed through the lifting hole at the end of the high-speed railway box girder and locked with a gasket and a nut. At this time, the high-speed railway box girder can be lifted. When a high-speed railway box girder of one type needs to be hoisted after another type of beam is hoisted, it is only necessary to move the hoisting rods in the large elliptical hole 3 and the small elliptical hole 4 to adjust their positions, so that various types of beams can be easily hoisted, which greatly improves work efficiency and safety. The general personnel can operate it, and after use, the device can be recycled and stored until the next use.
