[0001] The invention belongs to the technical field of construction, and more specifically, relates to a steel cage hoisting device. Background Art

[0002] The sea ranch breakwater generally adopts a bottomless cylinder structure with a diameter of more than 30m, a height of 40m, and a weight of over 4,000t. Its size and weight are both large. The bottomless cylinder structure is generally a cylindrical reinforced concrete structure with a steel cage inside. Most of the steel cages are made using traditional prefabrication technology. The semi-finished steel bars such as the vertical bar group are hoisted to the operating platform by a crane, and then the ring bars and vertical bars are placed manually, that is, the steel bars are tied on the operating platform.

[0003] Since the steel cage and vertical reinforcement group are both huge in size, they are particularly prone to deformation during the lifting process. Summary of the invention

[0004] The purpose of the embodiment of the present invention is to provide a steel cage hoisting device to solve the technical problem in the prior art that the steel cage is easily deformed during the hoisting process.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: to provide a steel cage lifting equipment, including a hook, an annular support, multiple lifting ropes and multiple clamp assemblies, the hook, the lifting rope, the annular support and the clamp assembly are arranged in sequence from top to bottom, one end of the lifting rope is connected to the hook, the other end of the lifting rope is connected to the annular support, and the ends of the multiple lifting ropes away from the hook are arranged in sequence along the circumference of the annular support, and the multiple clamp assemblies are arranged in sequence along the circumference of the annular support, and the clamp assemblies are used to clamp the vertical bars of the steel cage.

[0006] In the above scheme, the steel cage hoisting equipment includes a hook, an annular support frame, a hoisting rope and a clamp assembly, one end of each hoisting rope is connected to the hook, and the other end is arranged circumferentially on the hoisting rope, so that the force of the annular support frame can be uniform. In addition, multiple clamp assemblies are arranged circumferentially on the annular support frame, which can clamp the steel cage at various locations in the circumference, so that the steel cage has clamping support at various locations in the circumference, and is not easy to deform during the hoisting process. In addition, there are more clamp assemblies, and the overall clamping force of the steel cage is greater, and the steel cage is not easy to fall, and the safety factor is higher.

[0007] Optionally, the lower side of the annular support has a first hanging portion, and the clamp assembly is rotatably connected to the first hanging portion.

[0008] In the above solution, the clamp assembly is connected to the lower side of the annular support frame, so that the connection between the clamp assembly and the annular support frame is facilitated. Moreover, the clamp assembly can rotate relative to the first hanging portion, and when the clamp assembly and the clamped vertical rib are not in a vertical equilibrium state, the clamp assembly and the vertical rib can rotate to a equilibrium state under the action of gravity.

[0009] Optionally, the annular support frame is an annular truss structure.

[0010] In the above solution, by arranging the annular support frame as an annular truss structure, the annular support frame has a greater bearing capacity with a lighter weight.

[0011] Optionally, the clamp assembly includes a driving member, a connecting rod assembly and a clamp housing, the connecting rod assembly includes a first connecting rod, a second connecting rod and a third connecting rod, the first connecting rod is connected to the driving member, the driving member can output linear motion, one end of the second connecting rod is rotationally connected to the first connecting rod, the other end of the second connecting rod is rotationally connected to the third connecting rod, the end of the third connecting rod away from the second connecting rod is rotationally connected to the clamp housing, the rotational connection between the second connecting rod and the third connecting rod is a clamping area, and the vertical rib is clamped between the clamp housing and the clamping area.

[0012] In the above scheme, by setting a first connecting rod that moves linearly, a second connecting rod that is rotationally connected to the first connecting rod, and a third connecting rod that is rotationally connected to the second connecting rod, the angles of the second connecting rod and the third connecting rod can be changed, and the vertical ribs are clamped at the rotational connection between the second connecting rod and the third connecting rod, which requires a lower driving force for the driving member.

[0013] Optionally, the number of the second connecting rod and the number of the third connecting rod are both two, the two second connecting rods are symmetrically arranged with respect to the first connecting rod, the two third connecting rods are symmetrically arranged with respect to the first connecting rod, and the number of the clamping areas is two.

[0014] In the above scheme, by setting two second connecting rods and two third connecting rods, the connecting rod assembly has two clamping areas, which can clamp the inner and outer vertical bars of the vertical bar group at the same time. It will be more stable when clamping the vertical bar group, thereby reducing the danger during lifting.

[0015] Optionally, the second connecting rod has an abutment portion at one end close to the third connecting rod, and the side of the abutment portion facing the clamp housing is the clamping area; or, the third connecting rod has an abutment portion at one end close to the second connecting rod, and the side of the abutment portion facing the clamp housing is the clamping area.

[0016] In the above scheme, by providing an abutment portion on the second link or the third link, when the link assembly is in the clamping state, only one link contacts the vertical rib, avoiding interference between other links and the vertical rib, and keeping the vertical rib in a stable clamping state.

[0017] Optionally, at least one of the clamping area and the clamp housing is provided with an anti-slip pad.

[0018] In the above scheme, by providing anti-skid pads, when the weight of the vertical reinforcement remains unchanged, the static friction of the vertical reinforcement can be increased, thereby further improving the safety of the lifting of the vertical reinforcement plate group.

[0019] Optionally, the first connecting rod is rotatably connected to the motion output end of the driving member.

[0020] In the above scheme, the angle of the connecting rod assembly can be adjusted by rotating the first connecting rod to connect the motion output end of the driving member. The angle of the connecting rod assembly can be adjusted automatically according to the posture of the vertical reinforcement when clamping the vertical reinforcement to avoid the situation where the vertical reinforcement cannot be clamped.

[0021] Optionally, the clamp assembly is rotatably connected to the annular support, the rotation axis of the clamp assembly relative to the annular support is the first rotation axis, the rotation axis of the first connecting rod relative to the motion output end of the driving member is the second rotation axis, and the first rotation axis and the second rotation axis are perpendicular to each other.

[0022] In the above scheme, by making the first rotating shaft and the second rotating shaft perpendicular, the first connecting rod can rotate in any direction relative to the annular support frame, so as to adjust the posture of the vertical ribs during clamping and keep the vertical ribs in balanced force.

[0023] Optionally, two clamp assemblies are arranged in the radial direction of the annular support.

[0024] In the above scheme, two clamp assemblies are arranged in the radial direction of the annular support, so that the clamp assembly close to the inner ring of the annular support clamps the inner vertical bars of the steel cage, and the clamp assembly close to the outer ring of the annular support clamps the outer vertical bars of the steel cage.

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] The sea ranch breakwater generally adopts a bottomless cylinder structure with a diameter of more than 30m, a height of 40m, and a weight of over 4,000t. Its size and weight are both large. The bottomless cylinder structure is generally a cylindrical reinforced concrete structure with a steel cage inside. Most of the steel cages are made using traditional prefabrication technology. The semi-finished steel bars such as the vertical bar group are hoisted to the operating platform by a crane, and then the ring bars and vertical bars are placed manually, that is, the steel bars are tied on the operating platform.

[0040] Since the steel cage and vertical reinforcement group are both huge in size, they are particularly prone to deformation during the lifting process, and there is a risk of the steel cage falling.

[0041] In order to solve the above technical problems, the present invention proposes a steel cage hoisting device, which includes a hook 10, an annular support frame 30, multiple hoisting ropes 20 and multiple clamp assemblies 40. The annular support frame 30 is connected to the hook 10 through multiple hoisting ropes 20, and multiple clamp assemblies 40 are arranged in sequence on the annular support frame 30 in a circumferential direction, so that the circumferential vertical ribs 61 of the steel cage 60 can be clamped to prevent the steel cage 60 from being deformed during the hoisting process, and the clamping force on the steel cage 60 can also be increased to prevent the steel cage 60 from falling.

[0042] The steel cage hoisting equipment provided by the embodiment of the present invention is now described. The steel cage hoisting equipment is used to hoist the steel cage 60, that is, to fix part of the structure of the steel cage 60 for easy binding. The steel cage 60 includes an inner layer structure and an outer layer structure. The inner layer structure includes an inner layer vertical rib 61 arranged circumferentially and a plurality of inner layer annular ribs arranged along the height direction of the steel cage 60. The plurality of inner layer vertical ribs 61 and the plurality of inner layer annular ribs are fixed to each other to form the inner layer structure. The outer layer structure includes an outer layer vertical rib 61 arranged circumferentially and a plurality of outer layer annular ribs arranged along the height direction of the steel cage 60. The plurality of outer layer vertical ribs 61 and the plurality of outer layer annular ribs are fixed to each other to form the outer layer structure. The outer layer structure and the inner layer structure can be connected and fixed by radial connecting ribs. The outer layer structure and the inner layer structure can also be not fixed. After binding is completed, cement canning can be directly carried out. Among them, the circumferential direction in the present invention refers to the circumferential direction of the steel cage 60, the radial direction refers to the radial direction of the steel cage 60, and the axial direction refers to the axial direction of the steel cage 60.

[0043] See also Figure 1 and Figure 2 The steel cage hoisting equipment includes a hook 10, an annular support frame 30, multiple lifting ropes 20 and multiple clamp assemblies 40. The hook 10, the lifting rope 20, the annular support frame 30 and the clamp assembly 40 are arranged in sequence from top to bottom. One end of the lifting rope 20 is connected to the hook 10, and the other end of the lifting rope 20 is connected to the annular support frame 30. One end of the multiple lifting ropes 20 away from the hook 10 is arranged in sequence along the circumference of the annular support frame 30. The multiple clamp assemblies 40 are arranged in sequence along the circumference of the annular support frame 30. The clamp assembly 40 is used to clamp the vertical reinforcement 61 of the steel cage 60.

[0044] The hook 10 can be used to connect with a mobile mechanism such as a mechanical arm. When the mobile mechanism is working, it can drive the entire steel cage lifting device to move to a predetermined area. The hook 10 can be a hook-shaped structure or an open-hole structure, as long as it can be connected with the mobile mechanism. Its specific structure is not limited by the name of "hook".

[0045] The annular support frame 30 is annular and has an inner surface and an outer surface, and the inner surface and the outer surface are coaxially arranged. The annular support frame 30 matches the size of the steel cage 60, and the inner diameter of the annular support frame 30 can be smaller than the inner diameter of the steel cage 60, and the outer diameter of the annular support frame 30 can be larger than the outer diameter of the steel cage 60, so that there can be sufficient space to install the clamp assembly 40, so that the clamp assembly 40 can face the vertical ribs 61 of the steel cage 60.

[0046] The lifting rope 20 is in the shape of a rope, such as a steel wire rope or other rope-shaped structure with high strength and capable of deformation. There are multiple lifting ropes 20, and each lifting rope 20 is used to connect the hook 10 and the annular support frame 30. Specifically, one end of the lifting rope 20 is connected to the hook 10, and the other end of the lifting rope 20 is connected to the annular support frame 30. The ends of the multiple lifting ropes 20 away from the hook 10 are distributed in an annular shape on the annular support frame 30, so that the annular support frame 30 is lifted by the lifting ropes 20 at all places in the circumference, and the force on the annular support frame 30 is more uniform. When the steel cage lifting equipment is lifting the steel cage 60, the steel cage 60 is more stable.

[0047] The clamp assembly 40 is used to clamp the vertical ribs 61 of the steel cage 60. Multiple clamp assemblies 40 are arranged in sequence and spaced apart along the circumference of the annular support frame 30, so that the vertical ribs 61 at various circumferential positions of the steel cage 60 can be clamped, thereby maintaining the annular structure of the steel cage 60 and reducing the deformation of the steel cage 60 during the lifting process.

[0048] When the steel cage 60 needs to be hoisted, the moving mechanism drives the entire steel cage hoisting equipment to move to the top of the steel cage 60, and then moves downward until the vertical reinforcement 61 enters the clamp assembly 40, and then the clamp assembly 40 clamps the vertical reinforcement 61. After completing the binding of the steel cage, the clamp assembly 40 releases the vertical reinforcement 61, and the steel cage hoisting equipment moves to other positions.

[0049] The steel cage hoisting equipment in the above embodiment includes a hook 10, an annular support frame 30, a hoisting rope 20 and a clamp assembly 40. One end of each hoisting rope 20 is connected to the hook 10, and the other end is arranged circumferentially on the hoisting rope 20, so that the force of the annular support frame 30 can be uniform. Moreover, a plurality of clamp assemblies 40 are arranged circumferentially on the annular support frame 30, and the steel cage 60 can be clamped at various locations in the circumference, so that the steel cage 60 has clamping support at various locations in the circumference, and is not easy to deform during the hoisting process. Moreover, there are more clamp assemblies 40, and the overall clamping force on the steel cage 60 is greater, and the steel cage 60 is not easy to fall, and the safety factor is higher.

[0050] In some embodiments of the present invention, the sling rope 20 and the hook 10 are connected by a rope buckle, and the rope buckle is fixed at one end of the sling rope 20. The setting of the rope buckle makes it easier to connect the sling rope 20 and the hook 10. The rope buckle can be hung on the hook 10 by pressing the rope buckle open. The elastic part inside the rope buckle automatically closes the rope buckle when the external force disappears.

[0051] In some embodiments of the present invention, the sling rope 20 and the annular support frame 30 are connected by a rope buckle, and the rope buckle is fixed at one end of the sling rope 20. The setting of the rope buckle makes it easier to connect the sling rope 20 and the hook 10. The rope buckle can be hung on the annular support frame 30 by pressing the rope buckle open. The elastic part inside the rope buckle automatically closes the rope buckle when the external force disappears.

[0052] In some embodiments of the present invention, the sling rope 20 is a sling, and both ends of the sling have rope buckles, which can be very conveniently connected to the hook 10 and the annular support frame 30.

[0053] In some embodiments of the present invention, see Figure 1 and Figure 2 The suspension rope 20 is connected to the top side of the annular frame, and the suspension rope 20 can be connected to the top of the annular frame without bending.

[0054] Optionally, the top of the annular frame has a second hanging portion, the second hanging portion has a second hanging hole, the hanging rope 20 can be passed through the second hanging hole, or the hanging rope 20 is connected to the second hanging hole through a rope buckle.

[0055] In some embodiments of the present invention, the length of the suspension rope 20 is adjustable. The length of the suspension rope 20 refers to the distance from the hook 10 to the second hanging portion of the annular frame. For example, the suspension rope 20 is arranged through the second hanging hole, and the length of the suspension rope 20 can be shortened by tightening the suspension rope 20. The tightened length of the suspension rope 20 is L, and the length of the suspension rope 20 is shortened by 2L.

[0056] In some embodiments of the present invention, see Figure 1 The annular support frame 30 is an annular truss structure. A truss is a structure formed by connecting rods to each other at both ends with hinges. A truss is a plane or space structure generally having triangular units composed of multiple straight rods. The truss rods mainly bear axial tension or pressure, thereby making full use of the strength of the material, reducing deadweight and increasing rigidity.

[0057] By configuring the annular brace 30 as an annular truss structure, the annular brace 30 has a greater load-bearing capacity with a lighter weight.

[0058] In some embodiments, see Figure 3 The annular support frame 30 includes an inner truss 32, an outer truss 31 and a radial connection truss 33. In this way, when subjected to forces in various directions, the truss rods bear the tensile and compressive forces, thereby improving the bearing capacity of the annular support frame 30 in various directions. Among them, the inner truss 32, the outer truss 31 and the radial connection truss 33 all have a triangular unit structure.

[0059] In some embodiments of the present invention, see Figure 1 The lower side of the annular support frame 30 has a first hanging portion 34, and the clamp assembly 40 is rotatably connected to the first hanging portion 34. Specifically, the clamp assembly 40 is rotatably connected to the lower side of the annular support frame 30.

[0060] By connecting the clamp assembly 40 to the lower side of the annular support 30, the connection between the clamp assembly 40 and the annular support 30 is facilitated. Moreover, the clamp assembly 40 can rotate relative to the first hanging portion 34. When the clamp assembly 40 and the clamped vertical rib 61 are not in a vertical equilibrium state, the clamp assembly 40 and the vertical rib 61 can rotate to a equilibrium state under the action of gravity.

[0061] In some embodiments, a first hanging hole 341 is opened on the first hanging portion 34, and a hinge hole is provided on the top of the clamp assembly 40. The first hanging hole 341 and the hinge hole are connected by a hinge shaft, thereby realizing a rotational connection between the clamp assembly 40 and the first hanging portion 34.

[0062] In some embodiments, the first hanging portion 34 is slidably connected to the annular support frame 30, and the sliding direction of the first hanging portion 34 is the radial direction of the annular support frame 30. In this way, the radial position of the clamp assembly 40 can be adjusted, so that the steel cage hoisting device can be applied to steel cages 60 of more sizes. Specifically, when the first hanging portion 34 slides to the corresponding position of the annular support frame 30, the clamp assembly 40 and the first hanging portion 34 can be locked by the locking structure. The specific type of the locking structure is not limited here.

[0063] In some embodiments of the present invention, see Figure 4 and Figure 5 , each clamp assembly 40 is arranged at intervals in the circumferential direction. On the same circumference, the number of clamp assemblies 40 may be the same as the number of vertical ribs 61, and one clamp assembly 40 clamps one vertical rib 61. Alternatively, on the same circumference, the number of clamp assemblies 40 is less than the number of vertical ribs 61, and one clamp assembly 40 clamps multiple vertical ribs 61. Alternatively, on the same circumference, the number of clamp assemblies 40 is less than the number of vertical ribs 61, and one clamp assembly 40 clamps one vertical rib 61, and some vertical ribs 61 are not clamped.

[0064] In some embodiments of the present invention, see Figure 6 and Figure 7 The clamp assembly 40 includes a driving member 42, a connecting rod assembly 43 and a clamp housing 41. The connecting rod assembly 43 includes a first connecting rod 431, a second connecting rod 432 and a third connecting rod 433. The first connecting rod 431 is connected to the driving member 42, and the driving member 42 can output linear motion. One end of the second connecting rod 432 is rotatably connected to the first connecting rod 431, and the other end of the second connecting rod 432 is rotatably connected to the third connecting rod 433. The end of the third connecting rod 433 away from the second connecting rod 432 is rotatably connected to the clamp housing 41. The rotational connection between the second connecting rod 432 and the third connecting rod 433 is a clamping area, and the vertical rib 61 is clamped between the clamp housing 41 and the clamping area.

[0065] When the driving member 42 works, the connecting rod assembly 43 works, and the distance between the connecting rod assembly 43 and the clamp housing 41 changes. When the distance between the connecting rod assembly 43 and the clamp housing 41 is the smallest, the vertical rib 61 is clamped between the connecting rod assembly 43 and the clamp housing 41. When the distance between the connecting rod assembly 43 and the clamp housing 41 gradually increases, the vertical rib 61 can be detached from the clamp assembly 40. Among them, one end of the vertical rib 61 is clamped between the connecting rod assembly 43 and the clamp housing 41. When the clamp assembly 40 clamps the vertical rib 61, the steel cage 60 is in a vertical state (the axial direction of the steel cage 60 is the vertical direction).

[0066] When clamping the steel cage 60, the steel cage hoisting device moves to the top of the steel cage 60, the clamp assembly 40 is in the open state, the steel cage hoisting device moves down to the vertical rib 61 between the connecting rod assembly 43 and the clamp housing 41, the driving member 42 drives the connecting rod assembly 43 to move, the distance between the connecting rod assembly 43 and the clamp housing 41 gradually decreases, and the vertical rib 61 is clamped. When releasing the steel cage 60, the driving member 42 drives the connecting rod assembly 43 to move, the distance between the connecting rod assembly 43 and the clamp housing 41 gradually increases, the vertical rib 61 and the clamp assembly 40 are separated from each other, and the steel cage hoisting device moves upward and away from the vertical rib 61.

[0067] The connecting rod assembly 43 includes a first connecting rod 431, a second connecting rod 432 and a third connecting rod 433. The first connecting rod 431 is connected to the driving member 42, and the driving member 42 can output linear motion. One end of the second connecting rod 432 is rotatably connected to the first connecting rod 431, and the other end of the second connecting rod 432 is rotatably connected to the third connecting rod 433. The end of the third connecting rod 433 away from the second connecting rod 432 is rotatably connected to the clamp housing 41. The rotational connection between the second connecting rod 432 and the third connecting rod 433 is a clamping area, and the vertical rib 61 is clamped between the clamp housing 41 and the clamping area.

[0068] The first connecting rod 431 is connected to the motion output end 421 of the driving member 42, and the first connecting rod 431 can reciprocate linearly. When the connecting rod assembly 43 is working, the first connecting rod 431 reciprocates linearly, the second connecting rod 432 and the third connecting rod 433 rotate, and the distance between the clamping area and the clamp housing 41 changes, so that the vertical rib 61 can be clamped or loosened. Specifically, Figure 6 , Figure 7 The middle clamp assembly 40 is in a state of clamping the vertical rib 61. Figure 6 In the state, when the first connecting rod 431 moves downward, the angle between the second connecting rod 432 and the third connecting rod 433 increases, the distance between the clamping area and the clamp housing 41 increases, and the vertical rib 61 and the clamp assembly 40 are separated from each other. It should be noted that the movement direction of the first connecting rod 431 can be a vertical direction or a direction close to the vertical direction. For the convenience of description, it is briefly referred to as "vertical direction" below.

[0069] By providing a first link 431 for linear motion, a second link 432 rotatably connected to the first link 431, and a third link 433 rotatably connected to the second link 432, the angle between the second link 432 and the third link 433 can be changed, and the vertical rib 61 is clamped at the rotational connection between the second link 432 and the third link 433, thereby requiring a lower driving force for the driving member 42.

[0070] In some embodiments, the driving member 42 is a hydraulic cylinder, which can output linear motion and bear a large load, and drives the first connecting rod 431 to move linearly in the vertical direction, and the motion output end 421 of the hydraulic cylinder is a hydraulic rod. Alternatively, the driving member 42 is a pneumatic cylinder, which can also output linear motion and drive the first connecting rod 431 to move linearly in the vertical direction, and the motion output end 421 of the pneumatic cylinder is a pneumatic rod.

[0071] In some embodiments, the second link 432 and the third link 433 are both set at an angle to the vertical direction. The smaller the angle between the second link 432 and the third link 433 and the vertical direction, the closer the second link 432 and the third link 433 are to the vertical direction, and the farther the clamping area is from the clamp housing 41; the larger the angle between the second link 432 and the third link 433 and the vertical direction, the closer the second link 432 and the third link 433 are to the horizontal direction, and the closer the clamping area is to the clamp housing 41.

[0072] In some embodiments of the present invention, see Figure 6 and Figure 7 , the number of the second connecting rod 432 and the third connecting rod 433 are both two, the two second connecting rods 432 are symmetrically arranged about the first connecting rod 431, the two third connecting rods 433 are symmetrically arranged about the first connecting rod 431, and the number of the clamping areas is two. The first connecting rod 431 is vertically arranged, one of the second connecting rod 432 and the third connecting rod 433 is arranged on the left side of the first connecting rod 431, and the other second connecting rod 432 and the third connecting rod 433 are arranged on the right side of the second connecting rod 432, so that the connecting rod assembly 43 is a symmetrical structure. In this way, the number of the clamping areas is two, and the clamp housing 41 also has two inner walls arranged oppositely, and a clamping space is formed between the two clamping areas and the corresponding inner walls of the clamp housing 41. In this embodiment, two vertical bars 61 arranged at intervals can be clamped at the same time. For example, the two clamping spaces can clamp the inner layer vertical bars 61 and the outer layer vertical bars 61 of the steel cage 60 respectively.

[0073] By providing two second connecting rods 432 and two third connecting rods 433, the connecting rod assembly 43 has two clamping areas, which can clamp the inner vertical reinforcement 61 and the outer vertical reinforcement 61 at the same time, making it more stable when clamping the steel cage 60, thereby reducing the danger during lifting.

[0074] In some embodiments, the first connecting rod 431, the second connecting rod 432 and the third connecting rod 433 are all rod-shaped structures, which can reduce the space occupied by the connecting rod assembly 43 as much as possible and avoid interference with other structures.

[0075] In some embodiments, the first connecting rod 431, the second connecting rod 432 and the third connecting rod 433 are all sheet structures. Accordingly, the clamping area of ​​the connecting rod assembly 43 is larger and can clamp multiple vertical bars 61 at the same time, which can improve the stability of the steel cage 60 during hoisting.

[0076] In some embodiments, the two clamping areas are respectively used to clamp vertical ribs 61 of the same length or different lengths, and can be applicable to vertical ribs 61 of various different lengths, with strong applicability.

[0077] In some embodiments of the present invention, the second connecting rod 432 has an abutment portion 434 at one end close to the third connecting rod 433, and the side of the abutment portion 434 facing the clamp housing 41 is a clamping area. The abutment portion 434 is located at the rotation connection between the second connecting rod 432 and the third connecting rod 433. When the clamp assembly 40 clamps the vertical rib 61, the abutment portion 434 and the inner wall of the clamp housing 41 cooperate with each other to clamp the vertical rib 61. When the connecting rod assembly 43 is in the clamping state, the abutment portion 434 is protruded relative to the third connecting rod 433 on the side facing the clamp housing 41, so that it contacts the vertical rib 61.

[0078] By providing the abutment portion 434 on the second connecting rod 432, when the connecting rod assembly 43 is in the clamping state, only the second connecting rod 432 contacts the vertical rib 61, avoiding interference between the third connecting rod 433 and the vertical rib 61, and keeping the vertical rib 61 in a stable clamping state.

[0079] Optionally, the abutment portion 434 is equivalent to a structure formed by increasing the size of one end of the second link 432 close to the third link 433 .

[0080] In some embodiments of the present invention, see Figure 6 and Figure 7 The third connecting rod 433 has an abutment portion 434 at one end close to the second connecting rod 432, and the side of the abutment portion 434 facing the clamp housing 41 is a clamping area. The abutment portion 434 is located at the rotation connection between the second connecting rod 432 and the third connecting rod 433. When the clamp assembly 40 clamps the vertical rib 61, the abutment portion 434 and the inner wall of the clamp housing 41 cooperate with each other to clamp the vertical rib 61. When the connecting rod assembly 43 is in the clamping state, the abutment portion 434 is protruded relative to the second connecting rod 432 on the side facing the clamp housing 41, so that it contacts the vertical rib 61.

[0081] By providing the abutment portion 434 on the third connecting rod 433, when the connecting rod assembly 43 is in the clamping state, only the third connecting rod 433 contacts the vertical rib 61, avoiding interference between the second connecting rod 432 and the vertical rib 61, and keeping the vertical rib 61 in a stable clamping state.

[0082] Optionally, the abutment portion 434 is equivalent to a structure formed by increasing the size of one end of the third link 433 close to the second link 432 .

[0083] In some embodiments of the present invention, see Figure 5 and Figure 6 , at least one of the clamping area and the clamp housing 41 is provided with an anti-skid pad 44. This embodiment includes the following three situations: the side of the clamping area facing the clamp housing 41 is provided with an anti-skid pad 44; the side of the clamp housing 41 facing the clamping area is provided with an anti-skid pad 44; the side of the clamping area facing the clamp housing 41 and the side of the clamp housing 41 facing the clamping area are both provided with an anti-skid pad 44. Specifically, when clamping the vertical rib 61, the anti-skid pad 44 contacts the vertical rib 61, which can increase the static friction force on the vertical rib 61 and reduce the probability of the vertical rib 61 sliding down.

[0084] By providing the anti-skid pad 44 , when the weight of the vertical rib 61 remains unchanged, the static friction of the vertical rib 61 can be increased, thereby further improving the safety of the lifting of the vertical rib 61 set.

[0085] In some embodiments, the anti-skid pad 44 is fixed to the clamping area or the clamp housing 41 by means of connectors such as screws. The anti-skid pad 44 is not easy to fall off and can withstand greater external forces (vertical forces).

[0086] In some embodiments, the anti-slip pad 44 is made of a material that can be deformed under pressure, such as a silicone pad or a rubber pad.

[0087] In some embodiments, the side of the anti-skid pad 44 for clamping the vertical rib 61 has anti-skid bumps, anti-skid bumps or anti-skid patterns, etc. The specific anti-skid structure is not limited here, as long as the surface roughness of the anti-skid pad 44 can be increased.

[0088] In some embodiments of the present invention, see Figure 6 and Figure 7 The first connecting rod 431 is rotatably connected to the motion output end 421 of the driving member 42. When the first connecting rod 431 rotates relative to the motion output end 421 of the driving member 42, the connecting rod assembly 43 swings, thereby adjusting the posture of the vertical rib 61, keeping the vertical rib 61 in a balanced state, and reducing the force acting on the clamp assembly 40 in the horizontal direction.

[0089] The first connecting rod 431 is rotated to connect the motion output end 421 of the driving member 42, so that the angle of the connecting rod assembly 43 can be adjusted. The angle of the connecting rod assembly 43 is automatically adjusted according to the posture of the vertical rib 61 when clamping the vertical rib 61, thereby avoiding the situation where the vertical rib 61 cannot be clamped.

[0090] In some embodiments of the present invention, see Figure 1 and Figure 6 , the clamp assembly 40 is rotatably connected to the annular support frame 30, the rotation axis of the clamp assembly 40 relative to the annular support frame 30 is the first rotation axis 451, the rotation axis of the first connecting rod 431 relative to the motion output end 421 of the driving member 42 is the second rotation axis 452, and the first rotation axis 451 and the second rotation axis 452 are perpendicular to each other. The first connecting rod 431 rotates around the first rotation axis 451 relative to the motion output end 421 of the driving member 42, and the clamp assembly 40 rotates around the second rotation axis 452 relative to the annular support frame 30. In this way, the connection structure between the first connecting rod 431 and the annular support frame 30 can be equivalent to a cross-axis connection structure, and the first connecting rod 431 can be universally rotated relative to the annular support frame 30. When the vertical rib 61 is tilted at any angle, the first connecting rod 431 can rotate relative to the annular support frame 30 until the vertical rib 61 is in a vertical state, thereby maintaining the stability and balance of the vertical rib 61 and reducing the force on the clamp assembly 40.

[0091] By making the first rotating shaft 451 and the second rotating shaft 452 perpendicular, the first connecting rod 431 can rotate in any direction relative to the annular support frame 30 to adjust the posture of the vertical rib 61 during clamping so that the vertical rib 61 maintains a balanced force.

[0092] In some embodiments, the first connecting rod 431 is connected to the annular support frame 30 via a cross-axis structure or a universal ball structure, so that the driving member 42 can rotate in any direction relative to the annular support frame 30 .

[0093] In some embodiments of the present invention, see Figure 6 and Figure 7 The lower side of the clamp housing 41 has a first avoidance space 411, and the opposite sides of the first avoidance space 411 are respectively used to cooperate with the corresponding clamping area to clamp the vertical rib 61. The clamp housing 41 also has a second avoidance space for avoiding the third connecting rod 433 and other structures. The first avoidance space 411 and the second avoidance space are interconnected, so that the connecting rod assembly 43 can move inside the clamp housing 41 without interfering with the clamp housing 41. The clamp housing 41 can not only protect the connecting rod assembly 43, but also provide a clamping side for the vertical rib 61.

[0094] In some embodiments of the present invention, see Figure 1The clamp shells 41 of the multiple clamp assemblies 40 are integrally formed, which can also be understood as the clamp shells 41 of the multiple clamp assemblies 40 are shared by each other. In this way, the clamp shells 41 of each clamp assembly 40 do not need to be installed and connected, which can simplify the installation and connection steps.

[0095] In some embodiments of the present invention, two clamp assemblies 40 are provided in the radial direction of the annular support frame 30. That is, a plurality of clamp assemblies 40 form an inner ring clamp, and a plurality of clamp assemblies 40 form an outer ring clamp, and the inner ring clamp is located outside the outer ring clamp. The inner ring clamp is used to clamp the inner layer vertical ribs 61 of the steel cage 60, and the outer ring clamp is used to clamp the outer layer vertical ribs 61 of the steel cage 60.

[0096] By arranging two clamp assemblies 40 in the radial direction of the annular support 30 , the clamp assembly 40 close to the inner circle of the annular support 30 clamps the inner vertical ribs 61 of the steel cage 60 , and the clamp assembly 40 close to the outer circle of the annular support 30 clamps the outer vertical ribs 61 of the steel cage 60 .

[0097] In some embodiments of the present invention, the steel cage lifting equipment also includes a control system 50 and a power supply. The control system 50 and the power supply can be arranged on the annular support frame 30. The power supply provides electrical energy to the driving parts 42 of each clamp assembly 40, and the power supply and the clamp assembly 40 are electrically connected to the control system 50, and the control system 50 controls the operation and stop of the clamp assembly 40.

[0098] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
