Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a simple lifting device for reinforcing cages of large-diameter bored piles. Background Technology

[0002] During the hoisting of large-diameter bored pile reinforcement cages, the cages are prone to deformation. Using traditional hoisting tools can lead to stress concentration and exacerbate deformation. Some construction sites use spreader beams to assist in hoisting the reinforcement cages; however, these beams are long, difficult to store and transport, and occupy significant construction space when not in use. Furthermore, each spreader beam is only suitable for one diameter of reinforcement cage. When a building contains bored piles of various diameters, multiple spreader beams are required to complete the installation of the corresponding reinforcement cages. Utility Model Content

[0003] This utility model was made to solve the above-mentioned technical problems. One of its objectives is to provide a simple hoisting device for large-diameter bored pile reinforcement cages, which is not easy to deform when hoisting large-diameter bored pile reinforcement cages, and can also be applied to the hoisting operation of bored pile reinforcement cages of various diameters.

[0004] Another objective of this invention is to provide a simple hoisting device for the reinforcing cage of large-diameter bored piles, which can be folded when not in use, does not occupy a large construction site, and is convenient for storage and transportation.

[0005] According to one embodiment of the present invention, a simple hoisting device for a large-diameter bored pile reinforcement cage is provided, comprising: a support rod, one end of which is provided with a plurality of positioning holes along its length; a sleeve, which is slidably sleeved on the support rod, and the side wall is formed with a through hole opposite to the positioning hole; fasteners, which are inserted into the through hole and the positioning hole; a first lifting lug, which is fixedly provided at the upper and lower ends of the sleeve; and a second lifting lug, which is fixedly provided at the other end of the support rod.

[0006] In one embodiment, the strut includes a first member and a second member joined together, with a connecting plate bolted to at least one side of the first member and the second member.

[0007] In one embodiment, a hinge is provided between the first and second rods.

[0008] As one implementation, the first and second lifting lugs are provided with shackles.

[0009] In one implementation, a connecting steel rope is provided between the two shackles at the upper end; the shackle at the lower end is connected to a hook via a steel wire rope.

[0010] According to one embodiment of the present invention, another simple hoisting device for large-diameter bored pile reinforcement cages is provided, comprising: a support rod with several positioning holes along the length of both ends; two sleeves slidably sleeved on the two ends of the support rod, with through holes formed on the side walls opposite to the positioning holes; fasteners passing through the through holes and positioning holes; and a first lifting lug fixedly disposed at the upper and lower ends of the sleeves.

[0011] In one embodiment, the strut includes a first member and a second member joined together, with a connecting plate bolted to at least one side of the first member and the second member.

[0012] In one embodiment, a hinge is provided between the first and second rods.

[0013] As one implementation, the first lifting lug is provided with a shackle.

[0014] In one implementation, a connecting steel rope is provided between the two shackles at the upper end; the shackle at the lower end is connected to a hook via a steel wire rope.

[0015] Based on the above description and practical application, the simple hoisting device for large-diameter bored pile reinforcing cages described in this utility model can, in actual use, adjust the distance between the left and right lifting lugs by sliding the position of the sleeve and coordinating with the insertion and limiting of the fasteners. This allows the lugs to be positioned directly above the two lifting points of the reinforcing cage, making the simple hoisting device suitable for reinforcing cages of different diameters. When hoisting large-diameter reinforcing cages, the two lifting lugs are positioned directly above the lifting points, ensuring the reinforcing cage is vertically supported and prevents deformation due to forces from other directions.

[0016] In addition, the strut is made up of a first member and a second member. When hoisting is not required, the strut can be disassembled into two shorter members for easy storage and transportation. Attached Figure Description

[0028] Example 1

[0029] This embodiment discloses a simple hoisting device for the reinforcing cage of a large-diameter bored pile. Please refer to [link / reference]. Figure 1 The simple hoisting device for the large-diameter bored pile reinforcement cage in this embodiment includes a support rod, a sleeve 3, fasteners 4, a first lifting lug 5, and a second lifting lug 6.

[0030] The left end of the support rod has several positioning holes 7 along its length. The sleeve 3 slides onto the support rod, and a through hole corresponding to the positioning hole 7 is formed on the side wall of the sleeve 3. Fasteners 4 are inserted into two opposite through holes and positioning holes 7 to connect the sleeve 3 and the support rod together. First lifting lugs 5 are fixedly installed at the upper and lower ends of the sleeve 3, and a second lifting lug 6 is fixedly installed at the right end of the support rod. In actual use, the distance between the first lifting lugs 5 and the second lifting lug 6 at the left and right ends can be adjusted by sliding the position of the sleeve 3 and coordinating with the insertion and limiting of the fasteners 4, so that the two types of lifting lugs can be positioned directly above the two lifting points of the reinforcing cage. This allows the simple lifting device for large-diameter bored pile reinforcing cages to be applicable to reinforcing cages of different diameters. With this simple lifting device for large-diameter bored pile reinforcing cages, when lifting large-diameter reinforcing cages, the two types of lifting lugs can be positioned directly above the lifting points of the reinforcing cage, ensuring that the reinforcing cage is vertically stressed and will not deform due to forces from other directions.

[0031] In one embodiment, the strut includes a first member 1 and a second member 2 joined together, with a connecting plate 8 bolted to at least one side of the first member 1 and the second member 2. Figure 1 As shown, the two ends of the connecting plate 8 are fixedly connected to the first rod 1 and the second rod 2 by bolts, respectively. This allows two relatively short rods to be combined into a longer support rod, making the device suitable for hoisting large-diameter bored pile reinforcement cages. When hoisting is not required, the support rod can be disassembled into two shorter rods for easy storage and transportation.

[0032] As one implementation, a hinge is provided between the first rod 1 and the second rod 2. When it is necessary to store the two rods, the connecting plate 8 can be removed and the rods can be folded directly around the hinge, so that the two components can be stored together at the same time and can be quickly spliced ​​together when used later.

[0033] As one implementation, shackles 9 are provided on both the first lifting lug 5 and the second lifting lug 6. By providing these shackles 9, it is convenient for the user to connect the device to the wire rope during lifting operations.

[0034] Furthermore, as one embodiment, a connecting steel rope 10 is provided between the two shackles 9 at the upper end, and a hook is connected to the shackle 9 at the lower end via a steel wire rope. Figure 1 As shown, the two shackles 9 at the upper end of the strut are connected together by a connecting steel rope 10, and the shackles 9 at the lower end of the strut are connected to a wire rope and a hook. During hoisting operations, the hook of the crane or other hoisting equipment can be directly suspended in the middle of the connecting steel rope 10, and the hook at the lower end of the strut can be directly suspended at the hoisting point of the reinforcing cage, making it convenient for users to quickly complete the hoisting operation of the reinforcing cage.

[0035] In one specific embodiment, the first rod 1 and the second rod 2 are 150*150*6mm square steel pipes with a length of 1.4m, the sleeve 3 is a 160*160*6mm square steel pipe with a length of 150mm, and the connecting plate 8 is a 300*150*10mm steel plate. The left half of the first rod 1 is continuously provided with multiple positioning holes 7. By sliding the sleeve 3, the distance between the two lifting lugs at the upper end of the support rod and the distance between the two lifting lugs at the lower end of the support rod can be adjusted, making the device suitable for hoisting steel cages with a diameter of 2m-2.8m.

[0036] In addition, to increase the connection strength between the first member 1 and the second member 2, a hinge can be installed between only one adjacent side of the two members, and the connecting plate 8 can be installed at the other three adjacent sides. When hoisting a heavy steel cage, the support rod will not break or deform significantly, which can improve the safety of the hoisting operation.

[0037] Example 2

[0038] This embodiment discloses a simple hoisting device for the reinforcing cage of a large-diameter bored pile. Please refer to [link / reference]. Figure 2 The simple hoisting device for the large-diameter bored pile reinforcement cage in this embodiment includes a support rod, two sleeves 3, fasteners 4 and a first lifting lug 5.

[0039] The left and right ends of the support rod are provided with several positioning holes 7 along the length direction. Two sleeves 3 are slidably fitted onto the two ends of the support rod, and through holes corresponding to the positioning holes 7 are formed on the side walls of the sleeves 3. Fasteners 4 are inserted into the corresponding through holes and positioning holes 7 to connect the sleeves 3 and the support rod together. First lifting lugs 5 are fixedly installed at the upper and lower ends of the two sleeves 3. In actual use, the distance between the first lifting lugs 5 at the left and right ends can be adjusted by sliding the position of the sleeves 3 and cooperating with the insertion limit of the fasteners 4, so that the two lifting lugs can be positioned directly above the two lifting points of the reinforcing cage. This allows the simple lifting device for large-diameter bored pile reinforcing cages to be applicable to reinforcing cages of different diameters. With this simple lifting device for large-diameter bored pile reinforcing cages, when lifting large-diameter reinforcing cages, the two lifting lugs can be positioned directly above the lifting points of the reinforcing cage, so that the reinforcing cage is vertically stressed and will not deform due to forces in other directions.

[0040] In one embodiment, the strut includes a first member 1 and a second member 2 joined together, with a connecting plate 8 bolted to at least one side of the first member 1 and the second member 2. Figure 2As shown, the two ends of the connecting plate 8 are fixedly connected to the first rod 1 and the second rod 2 by bolts, respectively. This allows two relatively short rods to be combined into a longer support rod, making the device suitable for hoisting large-diameter bored pile reinforcement cages. When hoisting is not required, the support rod can be disassembled into two shorter rods for easy storage and transportation.

[0041] As one implementation, a hinge is provided between the first rod 1 and the second rod 2. When it is necessary to store the two rods, the connecting plate 8 can be removed and the rods can be folded directly around the hinge, so that the two components can be stored together at the same time and can be quickly spliced ​​together when used later.

[0042] As one implementation, each of the first lifting lugs 5 is provided with a shackle 9. By providing the shackle 9, it is convenient for the user to connect the device to the wire rope during lifting operations.

[0043] Furthermore, as one embodiment, a connecting steel rope 10 is provided between the two shackles 9 at the upper end, and a hook is connected to the shackle 9 at the lower end via a steel wire rope. Figure 1 As shown, the two shackles 9 at the upper end of the strut are connected together by a connecting steel rope 10, and the shackles 9 at the lower end of the strut are connected to a wire rope and a hook. During hoisting operations, the hook of the crane or other hoisting equipment can be directly suspended in the middle of the connecting steel rope 10, and the hook at the lower end of the strut can be directly suspended at the hoisting point of the reinforcing cage, making it convenient for users to quickly complete the hoisting operation of the reinforcing cage.

[0044] In one specific embodiment, the first rod 1 and the second rod 2 are 150*150*6mm square steel pipes with a length of 1.4m, the sleeve 3 is a 160*160*6mm square steel pipe with a length of 150mm, and the connecting plate 8 is a 300*150*10mm steel plate. The left half of the first rod 1 and the right half of the second rod 2 are continuously provided with multiple positioning holes 7. By sliding the sleeve 3, the distance between the two lifting lugs at the upper end of the support rod and the distance between the two lifting lugs at the lower end of the support rod can be adjusted, making the device suitable for hoisting steel cages with a diameter of 1.4m-2.8m.

[0045] In addition, to increase the connection strength between the first member 1 and the second member 2, a hinge can be installed between only one adjacent side of the two members, and the connecting plate 8 can be installed at the other three adjacent sides. When hoisting a heavy steel cage, the support rod will not break or deform significantly, which can improve the safety of the hoisting operation.
