Description

Technical Field

[0001] The utility model relates to the technical field of rod hoisting, in particular to an I-shaped rod hoisting device. Background Art

[0002] In a steel structure bridge, due to its high bending resistance, the I-shaped rod can bear a large amount of bending force, and has a series of advantages such as simple structure and convenient manufacturing, so it is widely used in various bridges with different spans and structural forms. However, due to the heavy self-weight and large volume of the I-shaped rod, and the rod generally adopts a double-sided stiffening structure and a double-sided welding method, a large number of flat-position welds are required to ensure the welding quality, so that the rod needs to be hoisted frequently. And the hoisting of the rod has certain potential safety hazards, and damage will occur at the hoisting position of the rod.

[0003] Currently, the commonly used hoisting tools include hooks, lifting suction cups, clamps, etc. In production, the hoisting of I-shaped rods often uses hooks and clamps. Since the lifting capacity of the lifting suction cup is limited, and the hoisting area is relatively large and requires a relatively high flatness, while the I-shaped rod is heavy and generally has transverse and longitudinal stiffeners arranged on the rod, so the lifting suction cup is generally not used for hoisting. And currently, most of the I-shaped rods are hoisted by clamps during the hoisting process. The clamp is easy to unhook, which is difficult to ensure the safety of the hoisting personnel. And when using the clamp for hoisting, there will be hoisting marks left on the I-shaped rod. And it takes a lot of time for the workshop to process the indentations generated by the rod hoisting, and there will still be marks after grinding treatment after painting, which affects the appearance of the rod.

[0004] Therefore, how to provide an I-shaped rod hoisting device has become an urgent technical problem to be solved by those skilled in the art. Summary of the Utility Model

[0005] The purpose of the utility model is to fill the gap existing in the prior art, and provides an I-shaped rod hoisting device, which reduces the potential safety hazards during the frequent hoisting of the I-shaped rod, solves the hoisting marks generated by the weight of the rod during the hoisting process, and ensures that the appearance quality of the rod meets the acceptance requirements.

[0006] To achieve the above purpose, the utility model provides an I-shaped rod hoisting device, including a hoisting short piece and a hoisting long piece. The hoisting short piece and the hoisting long piece are fixedly connected by bolts. A hoisting groove I is formed in the bent part of the hoisting short piece, and a hoisting groove II is formed in the bent part of the hoisting long piece. The hoisting groove I and the hoisting groove II are in corresponding positions.

[0007] Further, a hoisting hole is formed in the hoisting long piece.

[0008] Further, a clamping groove is arranged at one end of the hoisting short piece close to the hoisting long piece, and one end of the hoisting long piece extends into the clamping groove.

[0009] Further, one end of the long hoisting member is horizontally provided with a plurality of first threaded holes, and the side wall of the clamping groove is provided with a second threaded hole matching with the first threaded hole, and a bolt penetrates through the second threaded hole and the first threaded hole.

[0010] The beneficial effects of the present utility model are as follows:

By using this device, the safety risk in the construction process is reduced, the manufacturing efficiency of the members is improved, the amount of surfacing and grinding is reduced, the appearance quality of the members is improved, and the safety and quality of the member manufacturing are ensured.

[0024] Such as Figures 1-4As shown in the figure, the utility model provides a lifting device for I-shaped members, which includes a short lifting piece 1 and a long lifting piece 2. The short lifting piece 1 and the long lifting piece 2 are fixedly connected by bolts 9. A first lifting groove 4 is formed in the bent part of the short lifting piece 1, and a second lifting groove 5 is formed in the bent part of the long lifting piece 2. The first lifting groove 4 and the second lifting groove 5 are in corresponding positions.

[0025] The I-shaped member lifting device of the utility model can avoid safety accidents caused by the unhooking of the member, and reduce potential safety hazards during construction. Moreover, the I-shaped member 3 will not produce lifting indentations during the lifting process, reducing the time for subsequent treatment of the appearance of the I-shaped member 3, and improving the manufacturing efficiency of the member. In addition, the size of the I-shaped member lifting device can be adjusted, and it can lift I-shaped members 3 with similar plate thicknesses and cross-sectional dimensions, improving the utilization rate of the lifting device.

[0026] To further optimize the technical solution, a lifting hole 6 is provided on the long lifting piece 2, and the lifting is carried out at the position of the lifting hole 6.

[0027] To further optimize the technical solution, a clamping groove is provided at one end of the short lifting piece 1 close to the long lifting piece 2, and one end of the long lifting piece 2 extends into the clamping groove. A plurality of first threaded holes 7 are provided in one end of the long lifting piece 2 in the horizontal direction, and second threaded holes 8 matching the first threaded holes 7 are provided on the side wall of the clamping groove. The bolt 9 passes through the second threaded hole 8 and the first threaded hole 7. By adjusting the corresponding positions of the first threaded holes 7 and different second threaded holes 8, it can adapt to I-shaped members 3 of different lengths.

[0028] The structure of the utility model is designed simply, reasonably, and is convenient for installation and operation. Using this lifting device reduces the safety risk of the operator during lifting, effectively solves the problem of lifting indentations generated during lifting, improves the appearance quality of the member, and ensures the finished product quality of the member. Compared with the previous lifting method, from the assembly and welding of an I-shaped member to the final finished product, there are 6 - 10 lifting indentations on the member. The repair welding and grinding treatment of the lifting marks on a single member requires 1 - 2 hours of working hours. Coupled with the weld flaw detection, it takes 1 day to process before proceeding to the next process. Using this device, the I-shaped member can proceed to the next process without treating the lifting marks, greatly improving the work efficiency, saving the material costs for surfacing welding and flaw detection, and reducing the manufacturing cost.

[0029] The operation process of the utility model is as follows:

[0030] 1) Select a suitable type of lifting device according to the cross-sectional dimensions of the I-shaped member 3. The material of the lifting device is cut by carbon steel flame cutting.

[0031] 2) To meet the technological requirements for ensuring that the I-shaped member 3 can be placed on the hoisting device, the hoisting groove 1 of the hoisting device and the hoisting groove 2 are cut with a +5 tolerance to ensure that the I-shaped member can be easily placed in the device.

[0032] 3) When using the hoisting device, the hoisting groove 2 of the hoisting long member 2 is fitted to one side of the upper flange of the I-shaped member 3, so that one side of the upper flange of the I-shaped member 3 is stuck inside the hoisting long member 2.

[0033] 4) Place the hoisting groove 1 of the hoisting short member 1 on the other side of the upper flange of the I-shaped member 3 to ensure that the upper flange of the I-shaped member 3 is stuck inside the hoisting short member 1.

[0034] 5) Connect the second threaded hole 8 of the hoisting short member 1 and the first threaded hole 7 on the hoisting long member 2 through the bolt 9, so that the I-shaped member 3 is stuck in the hoisting device.

[0035] 6) Fix it with a snap ring on the hoisting hole 6 of the hoisting long member 2, and use a trolley to hoist the I-shaped member 3 to the appropriate position.

[0036] The above is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
