Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and specifically to a steel cage transfer and hoisting device. Background Technology

[0002] For the hoisting of medium and large steel cages, a multi-point coordinated hoisting method is usually adopted. By installing lifting devices at the pre-set lifting points at both ends of the steel cage, two cranes are used to lift the steel cage horizontally, then flip it over, and finally lower it vertically. This ensures that the steel cage structure is subjected to balanced forces during the hoisting process. For the hoisting of small steel cages, the horizontally placed steel cage is usually first lifted to a vertical position with the help of auxiliary equipment or manual labor. Then, hooks are connected to the top of the steel cage or the pre-set lifting points, and the crane is used to complete the hoisting and transfer.

[0003] However, the existing technology has the following problems:

[0004] When hoisting existing small steel cages, the lifting equipment usually only lifts one or two lifting points. This causes the steel cage to deform at the lifting points due to the concentrated stress after hoisting. Furthermore, uneven stress at the lifting points may cause the steel cage to tilt during hoisting, affecting the hoisting operation. Summary of the Invention

[0005] The purpose of this invention is to provide a steel cage transfer and hoisting device to solve the above-mentioned problems and overcome the defects of the prior art, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a rebar cage transfer and hoisting device, comprising a mounting base; a hoisting assembly is provided on the mounting base, the hoisting assembly including a sliding shaft, a grooved plate, and multiple sliders, the sliding shaft being slidably connected to the mounting base, the grooved plate being rotatably connected to the bottom of the mounting base, and the multiple sliders being slidably connected to the bottom of the mounting base in a circumferential array, with a support plate connected to each slider, and a lifting rod connected to the support plate; when the sliding shaft moves upward on the mounting base, it can indirectly trigger the multiple lifting rods to move outward synchronously, and after the multiple lifting rods move outward, they can lock the rebar cage from the inside out; the hoisting assembly also includes an auxiliary release part, used to assist the lifting rods in releasing the gap of the rebar cage during unloading; a lifting tool part is provided at the bottom of the sliding shaft, the lifting tool part being used for conventional hoisting operations.

[0008] Preferably, a limiting mechanism is provided between the sliding shaft and the mounting base, so that the sliding shaft can only slide vertically on the mounting base and cannot rotate. A spring is provided between the sliding shaft and the mounting base, and a lifting lug is provided at the top end of the sliding shaft and the top end of the mounting base, respectively.

[0009] Preferably, the outer wall of the sliding shaft is provided with multiple threaded grooves in a circumferential array, the grooved plate is sleeved on the outer wall of the sliding shaft, and multiple sliding tongues are installed on the inner side of the grooved plate. The multiple sliding tongues are slidably connected to the multiple threaded grooves respectively. When the sliding shaft slides vertically, it can drive the grooved plate to rotate by the cooperation of the multiple threaded grooves and the multiple sliding tongues.

[0010] Preferably, the slotted plate is provided with multiple arc-shaped grooves, and the slider is connected to a roller. The multiple rollers are slidably connected to the multiple arc-shaped grooves of the slotted plate. When the slotted plate rotates, it can drive the multiple sliders to move synchronously away from the slotted plate through the cooperation of the multiple arc-shaped grooves and the multiple rollers.

[0011] Preferably, the inner wall of the boom is rotatably connected to a rotating shaft, and a fastener is connected to the rotating shaft. The fastener is located at the end of the boom away from the support plate. The cross-section of the fastener is rectangular and matches the cross-section of the boom. The rotating shaft has a straight groove and a curved groove, which are connected. The outer wall of the mounting base is connected to multiple connecting frames, and sliding rods are connected to the connecting frames. The multiple sliding rods are slidably connected to the straight grooves on the multiple rotating shafts. When the sliding rods contact the curved grooves of the rotating shaft, they can drive the rotating shaft to rotate.

[0012] Preferably, multiple auxiliary release parts are provided, and each of the multiple auxiliary release parts is connected to multiple connecting frames. Each auxiliary release part includes a connecting rod, a rotating rod, an elastic rod, a slide block, a pair of connecting rods, a pair of slot blocks, and a smooth rod. The connecting rod is mounted on the connecting frame, the rotating rod is hinged to the connecting rod, the elastic rod is connected to the rotating rod, the slide block is vertically slidably connected to the outer wall of the mounting base, the pair of connecting rods are hinged to the slide block, and the end of the connecting rod away from the slide block is hinged to the support plate below the slide block. The pair of slot blocks are connected to the slide block, and the smooth rod is connected through the rotating rod. The slot block is provided with a horizontal slot, and the smooth rod is slidably connected to the horizontal slot of the two slot blocks. When the support plate moves horizontally, it can drive the slide block to move vertically through the pair of connecting rods. When the pair of slot blocks move vertically, they can drive the rotating rod to swing through the smooth rod. The elastic rod is made of elastic material.

[0013] Preferably, a protective cover is connected to the bottom of the mounting base, which is used to protect the tray and multiple rollers.

[0014] Preferably, the lifting device includes a fixed seat, a rotating seat, and a hook. The fixed seat is installed at the bottom of the sliding shaft, the rotating seat is rotatably connected to the bottom of the fixed seat, and the hook is connected to the bottom of the rotating seat. The outer wall of the rotating seat is connected with multiple locking blocks in a circumferential array, and multiple locking slots are provided between the multiple locking blocks. The bottom of the protective cover is connected to two locking rods, both of which pass through the fixed seat. When the fixed seat moves upward, the two locking rods can be inserted into two of the locking slots between the multiple locking blocks to restrict the rotation of the rotating seat.

[0015] Preferably, the top of the mounting base is equipped with two handles, and the outer wall of the mounting base is connected with four support wheels in a circumferential array.

[0016] The beneficial effects are:

[0017] 1. This rebar cage transfer and hoisting device, through the arrangement of the hoisting components, allows multiple lifting rods to contact the stirrups of the rebar cage during hoisting, forming multiple lifting points. Furthermore, because the multiple lifting rods are evenly distributed in a circumferential array, the stress applied to the rebar cage by the multiple lifting rods is relatively uniform. After the rebar cage is hoisted, it can maintain a relatively vertical state, avoiding deformation of the lifting points and tilting of the rebar cage due to uneven stress. Moreover, after the multiple lifting rods are moved into position, the buckle blocks at the ends of the lifting rods protrude from the top surface of the lifting rods by rotation, forming an anti-slip structure, preventing some of the stirrups of the rebar cage from slipping off the lifting rods during hoisting, further improving the safety of the hoisting operation.

[0018] 2. The steel cage transfer and hoisting device, through the setting of the auxiliary detachment part, enables multiple lifting rods to move inward during unloading, while multiple elastic rods swing synchronously and contact the stirrups of the steel cage. This allows the mounting seat to move to the center of the steel cage, thereby enabling multiple lifting rods to detach from the stirrups at the same time. This avoids the need for multiple adjustments to the position of the mounting seat due to individual lifting rods failing to detach from the stirrups in time, which would affect the efficiency of the operation.

[0019] 3. This steel cage transfer and hoisting device, through the setting of the lifting tool section, enables the hook to perform conventional hoisting operations, and the rotating seat can rotate on the fixed seat, allowing the hook to flexibly adjust its angle by rotation, which facilitates hoisting operations. After hoisting, two locking rods are inserted into two slots for limiting, at which point the rotating seat can no longer rotate, avoiding the rotation of the rotating seat and hook during hoisting, which could cause the hoisted object to rotate and sway, thus improving the safety of hoisting operations.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0040] Example 1: When hoisting existing small steel cages, the lifting equipment usually only lifts one or two lifting points. As a result, after the steel cage is lifted, the stress at the lifting points is relatively concentrated, which can easily lead to deformation of the lifting points. In addition, uneven stress at the lifting points may also cause the steel cage to tilt during hoisting, which affects the hoisting operation. This example is invented to solve the above problems.

[0041] Please see Figure 1 - Figure 7 A rebar cage transfer and hoisting device includes: a mounting base 1; a hoisting assembly 2 is provided on the mounting base 1, the hoisting assembly 2 includes a sliding shaft 21, a grooved plate 23 and multiple sliders 25, the sliding shaft 21 is slidably connected to the mounting base 1, the grooved plate 23 is rotatably connected to the bottom of the mounting base 1, the multiple sliders 25 are slidably connected to the bottom of the mounting base 1 in a circumferential array, the sliders 25 are connected to a support plate 27, the support plate 27 is connected to a lifting rod 28, when the sliding shaft 21 moves upward on the mounting base 1, it can indirectly trigger the multiple lifting rods 28 to move outward synchronously, after the multiple lifting rods 28 move outward, they can lock the rebar cage from the inside out, the support plate 27 is used to support the rebar cage from the inside out, when the multiple support plates 27 support the inner wall of the rebar cage, the lifting rods 28 on the multiple support plates 27 can pass through the gaps on the rebar cage, when the multiple lifting rods 28 move upward, the multiple lifting rods 28 can form multiple lifting points, thereby hoisting the rebar cage.

[0042] Furthermore, a limiting mechanism is provided between the sliding shaft 21 and the mounting base 1, so that the sliding shaft 21 can only slide vertically on the mounting base 1 and cannot rotate. A spring is provided between the sliding shaft 21 and the mounting base 1. Lifting lugs are provided at the top of the sliding shaft 21 and the top of the mounting base 1, respectively. The crane is usually equipped with two sets of cables, which can lift independently. One cable is connected to the mounting base 1 through the lifting lug, and the other cable is connected to the sliding shaft 21 through the lifting lug. During hoisting, the steel cage is first lifted, and then the crane is controlled to lift the mounting base 1 into the opening at the top of the steel cage. Finally, the cable connected to the sliding shaft 21 is driven to rise, so that the sliding shaft 21 starts to move upward first. At this time, the mounting base 1 remains stationary. When the sliding shaft 21 moves upward, it compresses the spring between itself and the mounting base 1.

[0043] In addition, the outer wall of the slide shaft 21 is provided with a plurality of threaded grooves 22 in a circumferential array. The grooved plate 23 is sleeved on the outer wall of the slide shaft 21. A plurality of sliding tongues 24 are installed on the inner side of the grooved plate 23. The sliding tongues 24 are slidably connected to the plurality of threaded grooves 22 respectively. When the slide shaft 21 slides vertically, it can drive the grooved plate 23 to rotate by the cooperation of the plurality of threaded grooves 22 and the plurality of sliding tongues 24. When the slide shaft 21 moves upward, the plurality of threaded grooves 22 move upward synchronously and apply force to the plurality of sliding tongues 24 respectively, so that the plurality of sliding tongues 24 slide along the plurality of threaded grooves 22. During this process, the plurality of sliding tongues 24 drive the grooved plate 23 to rotate.

[0044] In addition, the slotted plate 23 is provided with multiple arc-shaped grooves, and the sliders 25 are connected to rollers 26. The multiple rollers 26 are slidably connected to the multiple arc-shaped grooves of the slotted plate 23. When the slotted plate 23 rotates, it can drive the multiple sliders 25 to move synchronously away from the slotted plate 23 through the cooperation of the multiple arc-shaped grooves and the multiple rollers 26. When the slotted plate 23 rotates, it applies a force to the multiple rollers 26 through the multiple arc-shaped grooves, so that the rollers 26 drive the sliders 25 to move away from the slotted plate 23 while sliding along the arc-shaped grooves, thereby achieving the technical effect of the multiple sliders 25 moving outward synchronously. The multiple support plates on the multiple sliders 25 27 moves outward synchronously and contacts the inner wall of the reinforcing cage, thus providing support from the inner wall. At this time, the lifting rods 28 on the multiple support plates 27 also pass through the gaps in the reinforcing cage. Then, the cable connected to the mounting base 1 is driven to rise, lifting the mounting base 1 and the sliding shaft 21 synchronously. After the multiple lifting rods 28 contact the stirrups of the reinforcing cage, multiple lifting points are formed. Since the multiple lifting rods 28 are evenly distributed in a circumferential array, the stress applied to the reinforcing cage by the multiple lifting rods 28 is relatively uniform. After the reinforcing cage is lifted, the reinforcing cage can maintain a relatively vertical state, avoiding deformation of the lifting points and tilting of the reinforcing cage due to uneven force on the lifting points.

[0045] It is worth noting that a rotating shaft 29 is rotatably connected to the inner wall of the suspension rod 28. A portion of the rotating shaft 29 is inserted into the slider 25 and rotatably connected to the slider 25. A fastener 210 is connected to the rotating shaft 29. The fastener 210 is located at the end of the suspension rod 28 away from the support plate 27. The cross-section of the fastener 210 is rectangular and matches the cross-section of the suspension rod 28. The rotating shaft 29 has a straight groove and a curved groove, which are connected. Multiple connecting brackets 211 are connected to the outer wall of the mounting base 1. A slide rod 212 is connected to 211. Multiple slide rods 212 are slidably connected to straight grooves on multiple rotating shafts 29. When the slide rod 212 contacts the curved groove of the rotating shaft 29, it can drive the rotating shaft 29 to rotate. When the slider 25 and the lifting rod 28 move outward, the rotating shaft 29 inside them also moves outward synchronously. In this process, the straight groove on the rotating shaft 29 contacts the slide rod 212 first, and then the curved groove contacts the slide rod 212. When the straight groove contacts the slide rod 212 first, the rotating shaft 29 does not rotate. As the slider 25 is about to move outward into position, the slide rod 212 enters the curved groove. During the outward movement of the curved groove, a force is applied to the slide rod 212. Since the slide rod 212 is stationary, it exerts a counter-force on the curved groove, causing the curved groove to drive the rotating shaft 29 to rotate. The rotation angle of the rotating shaft 29 does not exceed 150 degrees. When the rotating shaft 29 rotates, it drives the buckle block 210 to rotate synchronously. When the buckle block 210 is not rotating, it is flush with the surface of the lifting rod 28. After the buckle block 210 rotates, because the cross-section of the buckle block 210 is rectangular, the buckle block 210 will protrude from the top surface of the lifting rod 28, forming an L-shaped anti-slip structure at the end of the lifting rod 28. Therefore, after multiple lifting rods 28 have moved outward into position, the buckle block 210 at the end of the lifting rod 28 protrudes from the top surface of the lifting rod 28 by rotation, forming an anti-slip structure. This prevents some of the stirrups of the steel cage from slipping off the lifting rod 28 during the lifting process, further improving the safety of the lifting operation.

[0046] It is worth noting that a protective cover 213 is connected to the bottom of the mounting base 1. The protective cover 213 is used to protect the tray 23 and multiple rollers 26. The protective cover 213 plays a good role in preventing impact and dust, and avoids damage to the transmission parts of the tray 23 and multiple rollers 26.

[0047] It is worth mentioning that the top of the mounting base 1 is equipped with two handles 5, and the outer wall of the mounting base 1 is connected with four support wheels 6 in a circular array. The two handles 5 make it easy for the staff to move the mounting base 1, while the four support wheels 6 facilitate the movement of the mounting base 1. The support wheels 6 do not obstruct the hoisting operation.

[0048] Example 2: Based on Example 1, after hoisting is completed, during unloading, some of the hoisting rods 28 may get stuck in the stirrup gaps of the steel cage, requiring multiple adjustments to the position of the mounting base 1 to remove them, which is quite troublesome. This example was invented to solve the above problem.

[0049] Please see Figure 1 , Figure 8 - Figure 10 The lifting assembly 2 also includes an auxiliary release section 3, used to assist the lifting rod 28 in releasing the gap of the reinforcing cage during unloading. Multiple auxiliary release sections 3 are provided, each connected to multiple connecting frames 211. Each auxiliary release section 3 includes a connecting rod 31, a rotating rod 32, an elastic rod 33, a slide block 34, a pair of connecting rods 35, a pair of slot blocks 36, and a smooth rod 37. The connecting rod 31 is mounted on the connecting frame 211, the rotating rod 32 is hinged to the connecting rod 31, the elastic rod 33 is connected to the rotating rod 32, the slide block 34 is vertically slidably connected to the outer wall of the mounting base 1, and a pair of connecting rods 35 are hinged to the slide block 34. The end of the connecting rod 35 away from the slide block 34 is hinged to the support plate 27 below the slide block 34. Next, a pair of slotted blocks 36 are connected to the slide block 34, and a smooth rod 37 is connected through the rotating rod 32. The slotted blocks 36 are provided with horizontal slots. When the smooth rod 37 and the horizontal slots of the two slotted blocks 36 are slidably connected to the support plate 27, the slide block 34 can be driven to move vertically through a pair of connecting rods 35 when the support plate 27 moves horizontally. When the pair of slotted blocks 36 move vertically, the rotating rod 32 can be driven to swing through the smooth rod 37. The elastic rod 33 is made of elastic material. After hoisting, the mounting base 1 and the sliding shaft 21 are lowered by the cable. Then, the lowering of the mounting base 1 is stopped, and the lowering of the sliding shaft 21 continues, so that the sliding shaft 21 is reset. The sliding shaft 21 is reset to the initial position under the elastic force of the spring between it and the mounting base 1. During this process, the slotted plate 23 rotates. This causes multiple sliders 25 to reset inwards, and multiple support plates 27 and multiple lifting rods 28 also reset inwards. When the support plate 27 moves outwards, it drives the slide block 34 to move downwards via a pair of connecting rods 35. The slide block 34 drives two slot blocks 36 to move downwards, and the two slot blocks 36 drive the rotating rod 32 to swing downwards via the smooth rod 37. The rotating rod 32 drives the elastic rod 33 to swing downwards. When the support plate 27 moves inwards, it drives the slide block 34 to move upwards via a pair of connecting rods 35. The slide block 34 drives the rotating rod 32 to swing upwards via the two slot blocks 36 and the smooth rod 37. The elastic rod 33 swings upwards accordingly. When the elastic rod 33 swings upwards and downwards, it will contact the stirrups of the reinforcing cage. After the elastic rod 33 contacts the stirrups of the reinforcing cage, it deforms and continues to swing until it detaches from the stirrups. When multiple elastic rods 33 simultaneously contact the stirrups of the reinforcing cage and deform, they simultaneously exert a force on the mounting seat 1 toward the center of the reinforcing cage, thereby forcing the mounting seat 1 back into the center of the reinforcing cage. Therefore, during unloading, as multiple lifting rods 28 move inward, multiple elastic rods 33 swing synchronously and contact the stirrups of the reinforcing cage, causing the mounting seat 1 to move to the center of the reinforcing cage. This allows multiple lifting rods 28 to detach from the stirrups simultaneously, avoiding the need for multiple adjustments to the position of the mounting seat 1 due to individual lifting rods 28 failing to detach from the stirrups in time, thus improving work efficiency.

[0050] Example 3: Based on Example 2, in actual construction, various conventional hoisting operations are required. However, hoisting component 2 is only suitable for steel cage hoisting operations and cannot be adapted to hoisting operations that require conventional hooks. This example was invented to solve the above problems.

[0051] Please see Figure 1 , Figure 2 , Figure 11 The bottom of the sliding shaft 21 is provided with a lifting device 4, which is used for conventional lifting operations. The lifting device 4 includes a fixed seat 41, a rotating seat 42 and a hook 43. The fixed seat 41 is installed at the bottom of the sliding shaft 21, the rotating seat 42 is rotatably connected to the bottom of the fixed seat 41, and the hook 43 is connected to the bottom of the rotating seat 42. The hook 43 can perform conventional lifting operations, and the rotating seat 42 can rotate on the fixed seat 41, so that the hook 43 can flexibly adjust its angle by rotating, which is convenient for lifting operations.

[0052] Furthermore, the outer wall of the rotating seat 42 is connected in a circumferential array with multiple locking blocks 44, and multiple slots are provided between the multiple locking blocks 44. The bottom of the protective cover 213 is connected to two locking rods 45, both of which pass through the fixed seat 41. When the fixed seat 41 moves upward, the two locking rods 45 can be inserted into two of the slots between the multiple locking blocks 44, thereby restricting the rotation of the rotating seat 42. After the sliding shaft 21 moves upward, the distance between the protective cover 213 and the fixed seat 41 is shortened, allowing the two locking rods 45 to be inserted into two of the slots between the multiple locking blocks 44. Before lifting, the workers can flexibly rotate the rotating seat 42 and the hook 43 to adjust the angle. After lifting, the two locking rods 45 are inserted into the two slots for limiting, at which point the rotating seat 42 can no longer rotate. This prevents the rotating seat 42 and the hook 43 from rotating during lifting, which could cause the lifted object to rotate and sway, thus improving the safety of the lifting operation.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
