Description

Technical Field

[0001] The present application relates to the field of steel cage hoisting equipment, and in particular to a recyclable steel cage hoisting structure. Background Art

[0002] Bored pile technology is a pile foundation construction technology widely used in construction projects, road and bridge projects and municipal projects. Its technical principle is to use a drilling rig to drill holes at designated locations, and after inspection and confirmation that the pile holes meet the requirements, a steel cage is placed and concrete is poured to form a pile body with bearing capacity.

[0003] In bored pile construction, due to the large size of the steel cage, it is usually necessary to use a crane to lift and fix it manually. However, when encountering some steel cages with larger diameters, it is difficult for workers to control the auxiliary lifting, which is more difficult. Usually, a lifting structure is installed on the steel mesh cage to perform fast and accurate lifting operations on the steel cage through the lifting structure.

[0004] A Chinese invention patent with application number "CN202111182018.4" discloses a circular lifting device for a steel cage, which includes a lifting component and a suspension component. The suspension component and the lifting component are connected by a connecting component. The suspension component is connected to the bottom of the steel cage, and the lifting component is connected to the lifting mechanism, so as to lift the steel cage. However, when the mass of the steel mesh cage is too large, there is a risk of deformation of the steel cage due to stress concentration. Utility Model Content

Thus, the positioning plate and the hoisting member are inserted into the inside of the steel reinforcement cage. The reinforcing bar structures at the upper and lower ends of the steel reinforcement cage are respectively located in the clamping groove and the positioning groove. The positioning groove is installed on the hoisting member to seal the clamping groove and the support groove. Thus, the reinforcing bar structures at the upper and lower ends of the steel reinforcement cage can be supported respectively through the hoisting member and the positioning plate, so that while the hoisting stability of the steel reinforcement cage can be improved, the problem of stress concentration during the hoisting of the steel reinforcement cage can be avoided, and the probability of damage to the steel reinforcement cage can be reduced.

[0014] By adopting the above technical solution, several support rods are arranged at equal intervals along the length direction of the hanger bar. Since the reinforcing bar structures in the steel reinforcement cage are arranged evenly, the support rods are arranged at equal intervals to ensure the uniform stress of each reinforcing bar structure arranged in the support groove, thus avoiding damage to the steel reinforcement cage.

[0015] In a specific feasible implementation scheme, a positioning plate sliding groove is formed at one end of the positioning plate away from the hanger bar, and the positioning plate is arranged through the positioning plate sliding groove and can slide in the positioning plate sliding groove.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0032] The embodiment of the present application discloses a recyclable steel reinforcement cage hoisting structure.

[0033] As Figure 1 shown, the recyclable steel reinforcement cage hoisting structure includes a suspension bar 1 and a positioning pin 2. One end of the suspension bar 1 is provided with a positioning plate 3, and the other end of the suspension bar 1 is provided with a lifting member 4. A support groove 42 corresponding to the reinforcing rib structure on the steel reinforcement cage is arranged on the lifting member 4, and a card slot 31 corresponding to the reinforcing rib structure is arranged on the positioning plate 3. The positioning pin 2 can be installed on the lifting member 4 to block the support groove 42 and the card slot 31. A pull ring 5 is installed at one end of the positioning pin 2.

[0034] As Figure 2As shown, the lifting component 4 is composed of a plurality of support rods 41, and the plurality of support rods 41 are evenly installed at equal intervals along the length direction of the lifting rod 1, and support grooves 42 are formed between adjacent support rods 41. A support rod slide groove 411 is provided at the end of the support rod 41 away from the lifting rod 1 corresponding to the positioning pin 2. The support rod 41 moves toward the steel cage away from the lifting rod 1, so that the support rod 41 can be inserted into the gap between the reinforcement rib structure of the steel cage, and then inserted into the plurality of support rod slide grooves 411 through the positioning pin 2, thereby blocking the support grooves 42 formed between adjacent support rods 41, so that the reinforcement rib structure can be installed in the support grooves 42, and at the same time, it can prevent the reinforcement rib structure from detaching from the support groove 42 when the steel cage is lifted. The diameter of the pull-out ring 5 arranged on the positioning pin 2 is larger than the diameter of the support rod slide groove 411, so that the positioning pin 2 can be clamped on the uppermost support rod 41 through the pull-out ring 5.

[0035] A plurality of support rods 41 are arranged at equal intervals along the length direction of the hanger 1. Since the reinforcement structure in the steel cage is evenly arranged, the support rods 41 are arranged at equal intervals to ensure that each reinforcement structure arranged in the support groove 42 is evenly stressed, and a plurality of support grooves 42 are formed between the support rods 41, so that a plurality of reinforcement structures can be supported, thereby further ensuring the stability of the lifting of the steel cage and the dispersed application of the force, thereby reducing the probability of damage to the steel cage.

[0036] like Figure 3 As shown, in the embodiment of the present application, the positioning plate 3 is configured as a U-shaped plate, and a U-shaped groove is formed between the two side plates of the U-shaped plate, and the U-shaped groove is the slot 31. The upper side plates of the positioning plate 3 are provided with a positioning plate slot 32 corresponding to the support rod slot 411 in the height direction. The positioning plate 3 is moved along one side of the opening of the slot 31, and the two side plates of the positioning plate 3 are inserted into the gap between the adjacent reinforcing rib structures at the lower end of the steel cage. The positioning pin 2 is then inserted into the positioning plate slot 32 to block the slot 31, thereby installing the reinforcing rib structure in the support slot 42. At the same time, it can prevent the reinforcing rib structure from falling off from the slot 31 when the steel cage is hoisted. Similarly, the setting of the pull ring 5 can facilitate pulling the positioning pin 2 to make it slide in the positioning plate slot 32.

[0037] like Figure 2 and Figure 3As shown, on the surface of the upper side of the upper end of the support rod 41 below the uppermost support rod 41 in the vertical direction, a lifting member limiting groove 43 is provided. On the upper surface of the side plate below the positioning plate 3 in the vertical direction, a positioning plate limiting groove 33 is provided corresponding to the lifting member limiting groove 43. In the embodiment of the present application, the lifting member limiting groove 43 and the positioning plate limiting groove 33 are set as arc-shaped grooves. In other embodiments, the lifting member limiting groove 43 and the positioning plate limiting groove 33 can be set as rectangular grooves or grooves of other shapes. In other embodiments, a limiting spring and a limiting plate can be provided. The limiting spring is installed below the uppermost support rod 41, and the limiting plate is connected to the end of the limiting spring away from the support rod 41. By applying a force to the limiting plate through the limiting spring, and then pressing the reinforcing rib structure through the limiting plate, it is ensured that the reinforcing rib structure is always located within the lifting member limiting groove 43 and the positioning plate limiting groove 33.

[0038] A lifting member limiting groove 43 is provided on the support rod 41, and a positioning plate limiting groove 33 is provided on the inner side wall of the positioning groove. The positioning plate limiting groove 33 and the lifting member limiting groove 43 are arranged on the same horizontal plane in the vertical direction, so as to ensure that the reinforcing rib structures at the upper and lower ends are respectively clamped in the positioning plate limiting groove 33 and the lifting member limiting groove 43. When the steel reinforcement cage is lifted, the steel reinforcement cage structure can be limited through the positioning plate limiting groove 33 and the lifting member limiting groove 43, avoiding the shaking of the steel reinforcement cage, and thus ensuring the stability during installation.

[0039] The implementation principle of a recyclable steel reinforcement cage lifting structure in the embodiment of the present application is as follows: Move the lifting bar 1 towards the steel reinforcement cage, and the opening sides of the card slot 31 and the support slot 42 face the steel reinforcement cage. Insert the two side plates of the support rod 41 and the positioning plate 3 into the gap between adjacent reinforcing rib structures of the steel reinforcement cage. Then, insert the positioning pin 2 into the support rod sliding groove 411, and make the positioning pin 2 slide in the support rod sliding groove 411, so as to insert into the lower positioning plate sliding groove 32. The lifting ring is clamped on the uppermost support rod 41, so as to realize the blocking of the card slot 31 and the support slot 42 through the positioning pin 2, and thus install the reinforcing rib structure in the card slot 31 and the support slot 42. Then, connect the hoisting mechanism to the uppermost support rod 41. After installing several lifting structures in the circumferential direction of the steel reinforcement cage according to the above steps, lift several lifting bars 1 simultaneously. The reinforcing rib structures at the upper and lower ends are respectively clamped in the lifting member limiting groove 43 and the positioning plate limiting groove 33, and then lift the steel reinforcement cage and install it at the predetermined position. Thus, the reinforcing rib structures at the upper and lower ends of the steel reinforcement cage can be supported by the lifting member 4 and the positioning plate 3 respectively, which can improve the lifting stability of the steel reinforcement cage while avoiding the problem of stress concentration during the lifting of the steel reinforcement cage, and thus reduce the probability of damage to the steel reinforcement cage.

[0040] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
