Description

A new type of Y-shaped pier column reinforcement cage integral lifting device

Technical Field

The present application relates to the technical field of a novel integral lifting sling for a pier column reinforcement cage, and in particular to a novel integral lifting sling for a Y-shaped pier column reinforcement cage.

Background Art

The hoisting technology has a long history in the construction field. According to the different hoisting objects, various process requirements have been derived. For lighter hoisting objects, steel wire ropes are often used for overall hoisting, while for large structures, different hoisting auxiliary tools need to be designed for actual construction. For example, the common prefabricated beam steel frame hoisting requires a special hoisting cradle. In the field of bridge pier construction, the common process is to tie the steel bars on site and then carry out subsequent operations and construction, but there are also advanced processes for overall hoisting on site after on-site processing. In order to adapt to such processes, different hoists need to be designed for auxiliary construction.

Due to its unique vertical structure and top fork structure, the Y-shaped pier column steel cage is different from horizontal lifting, which can use large lifting equipment (such as gantry crane or truss crane), and different from pile foundation steel cage, which can be lifted in sections to reduce the lifting weight and can be assisted by simple tools. However, the Y-shaped pier column steel cage faces the disadvantages of heavy structure, easy deformation, and easy deflection during the lifting process when hoisting as a whole. Ordinary lifting tools are not suitable for this kind of structure.

The slings in the prior art usually include a sling body, a lifting ear welded and fixed to the sling body, and an upper lifting rope and a lower lifting rope fixedly connected to the lifting ear. Currently, the lifting ear is usually welded and fixed to the sling body to increase its stability. However, the Y-shaped pier column steel bars have different forms during the lifting process, such as inclined lifting, horizontal lifting and vertical lifting. When converting to different forms, it is currently done by adjusting the distance between the upper lifting rope and the hook, that is, adjusting the length of the upper lifting rope. For example, when lifting at an angle, the lengths of the two upper lifting ropes are different, that is, the workpiece tilts after lifting. This method cannot accurately control the adjustment angle.

In view of this, technical personnel in this field need to develop a new type of Y-shaped pier column reinforcement cage integral lifting device to address the above technical problems.

Utility Model Content

The main purpose of the present application is to provide a new type of Y-shaped pier column steel cage integral lifting sling, which not only has high connection strength, but also does not require welding of the lifting lugs to the sling body, thus avoiding the preparation of welding process, and can adjust the inclination angle of the workpiece after lifting by adjusting the position between the lifting lugs and the sling body.

In order to achieve the above-mentioned objectives, in the first aspect, the present application provides a novel Y-shaped pier column steel cage integral lifting sling, comprising a sling body, two lifting ears fixedly arranged on the sling body, upper lifting ropes fixedly connected to the upper ends of the lifting ears, and lower lifting ropes fixedly connected to the lower ends of the lifting ears, a positioning structure is arranged between the lower lifting rope and the sling body, the positioning structure comprises a plurality of conical positioning holes opened at the bottom of the sling body along the length direction of the sling body, a positioning block fixedly arranged on the lower lifting rope, a through hole is opened on the bottom surface of the lifting ear, the positioning block comprises a first conical portion and a second conical portion, the first conical portion cooperates with the conical positioning hole, the maximum size of the second conical portion is larger than the size of the through hole, and the lower lifting rope passes through the through hole.

As a further improvement, the tapered positioning hole is a conical hole, and the first tapered portion and the second tapered portion are both truncated cone structures.

A further improvement is that the sling body is welded from two shoulder pole beams.

A further improvement is that the upper hanging rope and the lower hanging rope are both steel wire ropes.

A further improvement is that the upper hanging ropes have two connected to the hooks, and the lower hanging ropes have four, which are fixedly connected to the positioning blocks on the corresponding sides in pairs.

A further improvement is that the lifting ear includes a supporting base plate and supporting side plates fixedly arranged on both sides of the supporting base plate, and the through hole is opened on the supporting base plate.

A further improvement is that round steel is welded and fixed on both sides of the supporting bottom plate and the supporting side plates on both sides.

A further improvement is that when the upper hoisting rope is in a tensioned state, the angle between it and the hoisting device body is 45°-60°.

A further improvement is that an auxiliary reinforcement rope is fixedly connected between each lower suspension rope and the suspension ear.

The utility model provides a novel Y-shaped pier column steel bar cage integral lifting sling, which has the beneficial effect compared with the prior art, by setting a positioning block to cooperate with the conical positioning hole at the bottom of the sling body, the second conical portion below the positioning block is inserted into the through hole, and the first conical portion is inserted into the conical positioning hole. During lifting, the positioning block is pressed into the conical positioning hole through the lifting ear, so that the lower lifting rope and the sling body and the lifting ear form a whole, with strong stability, and when adjustment is needed, the position of the lifting ear can be directly adjusted, avoiding the disadvantage that the current welding fixation cannot be adjusted, and avoiding the preparation of welding process. In addition, by setting an auxiliary reinforcement rope, after lifting, the lower lifting rope and the lifting ear are connected at multiple points, which has stronger stability and higher safety factor.

As shown in Figures 1 to 3, a new type of Y-shaped pier column steel cage integral lifting sling includes a sling body 1, two lifting ears 2 fixedly arranged on the sling body 1, upper lifting ropes 3 fixedly connected to the upper ends of the lifting ears 2, and lower lifting ropes 5 fixedly connected to the lower ends of the lifting ears 2. A positioning structure is arranged between the lower lifting rope 5 and the sling body 1. The positioning structure includes a plurality of conical positioning holes 7 opened at the bottom of the sling body 1 along the length direction of the sling body 1, and a positioning block 6 fixedly arranged on the lower lifting rope 5. A through hole 8 is opened on the bottom surface of the lifting ear 2. The positioning block 6 includes a first conical portion and a second conical portion. The first conical portion cooperates with the conical positioning hole 7, and the maximum size of the second conical portion is larger than the size of the through hole 8. The lower lifting rope 5 passes through the through hole 8. In addition, in order to ensure the strength and stability of the connection, an auxiliary reinforcement rope 9 is fixedly connected between each of the lower lifting ropes 5 and the lifting ear 2, and the connection method between the auxiliary reinforcement rope 9 and the lifting ear 2 can adopt a conventional connection method.

In order to facilitate positioning, the conical positioning hole 7 is a conical hole, and the first conical part and the second conical part are both truncated cone structures. When it is necessary to adjust the tilt position of the workpiece after lifting, it is only necessary to loosen the lifting ear 2, slide the lifting ear 2 to the corresponding position along the sling body 1, and insert the positioning piece into the corresponding conical positioning hole 7. After lifting, the hook 4 lifts the lifting ear 2 through the upper lifting rope 3. After the lifting ear 2 is subjected to force, the positioning piece is pressed into the conical positioning hole 7, so that the sling body 1, the lower lifting rope 5 and the lifting ear 2 form a whole, which is more stable.

In order to ensure the strength, the sling body 1 is welded from two shoulder pole beams, and a fully welded I-beam of no less than double-jointed I18 is used as the shoulder pole beam. The model and force performance of the I-beam must fully meet the relevant national and industry steel structure specifications. The length of the sling body is consistent with the horizontal spacing between the top hanging points of the Y-shaped pier column steel cage, which is generally 1.8 to 2.0 m. In addition, preferably, the upper hanging rope 3 and the lower hanging rope 5 are both steel wire ropes, and the upper hanging rope 3 has two ropes, both of which are connected to the hook 4, and the lower hanging rope 5 has four ropes, which are fixedly connected to the corresponding positioning blocks 6 in pairs.

Preferably in this embodiment, the lifting ear 2 includes a supporting base plate and supporting side plates fixedly arranged on both sides of the supporting base plate, and the through hole 8 is opened on the supporting base plate. In order to improve the strength of the lifting ear 2, round steel with a diameter of not less than φ28 is welded and fixed on both sides of the supporting base plate and the supporting side plates on both sides, and the side surfaces of the round steel are tightly welded to the supporting side plates and the supporting base plate. The same type of segmented steel bars are used for auxiliary welding to ensure that the round steel and the lifting ear 2 are connected as a whole. The spacing between the lifting ears 2 is appropriately adjusted according to the length of the wire rope at the upper hanging point, generally about 50 cm away from the end of the sling body, to ensure that the angle between the upper hanging rope 3 and the sling body 1 is 45°-60° when the upper hanging rope 3 is in a tensioned state.

During construction, two steel wire ropes are used to connect the upper hanging point to the main hook of the crane, and four steel wire ropes are used to connect the lower hanging point to the top hanging point of the Y-shaped pier reinforcement cage. During overall lifting, the steel wire ropes are evenly stressed together, slowly lifted and rotated vertically, and slowly lowered. As a result, the overall structure is stable and firm, with a large lifting weight and can be reused. The structure is simple to process, the materials are common, and it is easy to process on site, which reduces the deflection of the Y-shaped pier reinforcement cage during lifting. It has low safety risks and can be applied to similar vertical lifting components with a wide range of applications.

The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
