Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to a hoisting device for a steel cage. Background Art

[0002] Currently, during the construction process, it is usually necessary to hoist the steel cage into the pile hole on the ground, and then pour concrete to form the pile foundation structure.

[0003] In the prior art, the lifting of the steel cage into the ground pile hole is mostly achieved by relying on lifting equipment. When lifting the steel cage, the existing lifting equipment mostly connects a cable to one end of the steel cage, then an electric hoist drives the cable to reel in, and uses the cable to pull one end of the steel cage, so that the steel cage is gradually erected and away from the ground. Finally, the lifting equipment controls the steel cage to move above the ground pile hole, and the electric hoist drives the cable to unwind, so as to lift the erected steel cage into the ground pile hole. This lifting method has at least the following defects:

[0004] 1. When the cable pulls one end of the steel cage, the other end of the steel cage touches the ground. Since the steel cage is heavy, it is easy to cause the steel cage to bend and deform;

[0005] 2. When the cable is unwound to lower the steel cage into the ground pile hole, the steel cage has poor stability and is prone to collision with the inner wall of the pile hole, causing damage to the steel cage and the inner wall of the pile hole, which is not conducive to the subsequent concrete pouring operation. Summary of the Invention

[0006] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a hoisting device for a steel cage.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A lifting device for a steel cage includes a bracket, a lifting assembly, a first limiting assembly, a first driving assembly, a second limiting assembly, and a second driving assembly.

[0009] The lifting assembly is installed on one side of the bracket and is used to drive the steel cage to move up and down along one side of the bracket.

[0010] The first limiting assembly and the second limiting assembly are arranged on one side of the bracket and are distributed relatively to each other, and the first driving assembly is arranged on the side wall of the bracket.

[0011] When the lifting assembly drives the steel cage to move upward, the first driving assembly is used to drive the first limiting assembly to be removed from one side of the second limiting assembly, so that the steel cage can be transformed from a horizontal posture to a vertical posture.

[0012] The second driving assembly is mounted on the side wall of the bracket, and after the steel cage is transformed from a horizontal posture to a vertical posture,

[0013] The second driving assembly is used to drive the first limiting assembly to move back to the side of the second limiting assembly, and the first limiting assembly and the second limiting assembly are respectively limited on both sides of the steel cage.

[0014] As a further improvement of the present invention: the second limiting assembly includes a second limiting roller,

[0015] One end of the second limiting roller is rotatably connected to the side wall of the bracket,

[0016] The first limiting component includes a first limiting roller,

[0017] One end of the first limiting roller passes through the bracket and extends to one side of the second limiting roller.

[0018] When the steel cage moves to the bottom of the second limiting roller, the first driving assembly is used to drive the first limiting roller to move in a direction perpendicular to the bracket, so that the first limiting roller is removed from one side of the second limiting roller.

[0019] When the steel cage acts on the second limiting roller and changes from a horizontal posture to a vertical posture, the second driving assembly is used to drive the first limiting roller to move in the opposite direction perpendicular to the bracket, so that the first limiting roller moves back to the side of the second limiting roller.

[0020] As a further improvement of the present invention: a first arc-shaped sliding groove and a second arc-shaped sliding groove are provided on the side wall of the bracket.

[0021] The first driving assembly includes a push rod, a limiting column and a driving circular plate.

[0022] The driving circular plate is rotatably arranged on one side of the bracket, one end of the push rod is connected to the eccentric position of one side of the driving circular plate, and the other end passes through the bracket from the second arc-shaped slide groove and extends to the bottom of the second limiting roller. A slope is provided on one side of the limiting column.

[0023] The first limiting roller passes through the driving circular plate from the eccentric position of the driving circular plate. One end of the first limiting roller is connected to the inclined surface on one side of the limiting column through a spherical protrusion, and the other end passes through the bracket from the first arc-shaped sliding groove and extends to the right side of the second limiting roller.

[0024] A baffle is further provided on the side wall of the first limiting roller, and the baffle is connected to the driving circular plate via an elastic member.

[0025] As a further improvement of the present invention: a first support plate is fixedly provided on one side of the bracket, a second support plate is fixedly provided on one end of the first support plate away from the bracket, and the limiting column is fixedly installed on one side of the second support plate.

[0026] As a further improvement of the present invention: the center position of one side of the driving circular plate is rotatably connected to the side wall of the bracket through a rotating rod. When the steel cage changes from a horizontal posture to a vertical posture, the second driving assembly is used to drive the first limiting roller of the driving circular plate to move in the opposite direction perpendicular to the direction of the bracket.

[0027] As a further improvement of the present invention: a sleeve is rotatably sleeved on one end of the first limiting roller away from the spherical protrusion, a first groove is provided on the circumferential side wall of the sleeve, and a second groove is provided on the circumferential side wall of the second limiting roller.

[0028] As a further improvement of the present invention: the lifting assembly includes an electric hoist on the top of the bracket and a cable connected to the output end of the electric hoist, and the end of the cable away from the electric hoist is connected to the middle part of the steel cage.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] In the embodiment of the present invention, when the steel cage needs to be hoisted, the lifting assembly can be used to drive the steel cage placed flat on the ground to move horizontally upward along one side of the bracket. When the steel cage moves to a certain height, the first driving assembly drives the first limiting assembly to be removed from the side of the second limiting assembly. Then the steel cage acts on the second limiting assembly to cause the steel cage to rotate under force until the steel cage changes from a horizontal posture to a vertical posture. The second driving assembly drives the first limiting assembly to move back to the side of the second limiting assembly. At this time, the first limiting assembly and the second limiting assembly are respectively limited to the opposite sides of the steel cage to ensure that the steel cage is stably in a vertical posture. The steel cage in the vertical posture is driven to move by the bracket to The lifting assembly then drives the steel cage downward, and through the restrictions of the first limit assembly and the second limit assembly, the steel cage in a vertical posture is steadily hoisted into the pile hole to complete the lifting operation of the steel cage. Compared with the existing technology, through the cooperation of the lifting assembly, the first limit assembly, the first drive assembly, the second limit assembly and the second drive assembly, the steel cage can be automatically adjusted to a vertical posture during the lifting process of the steel cage, and when the steel cage is subsequently hoisted into the ground pile hole, it can provide a guiding effect for the steel cage, ensuring that the steel cage stably enters the pile hole without colliding with the inner wall of the pile hole, thereby improving the safety and convenience of the steel cage hoisting process.

DETAILED DESCRIPTION

[0036] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0037] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] See also Figure 1 and Figure 3The present embodiment provides a lifting device for a steel cage, including a bracket 10, a lifting assembly 20, a first limiting assembly 30, a first driving assembly 40, a second limiting assembly 50 and a second driving assembly 60. The lifting assembly 20 is installed on one side of the bracket 10 and is used to drive the steel cage to move up and down along the side of the bracket 10. The first limiting assembly 30 and the second limiting assembly 50 are arranged on one side of the bracket 10 and are relatively distributed. The first driving assembly 40 is arranged on the side wall of the bracket 10. When the lifting assembly 20 drives the steel cage to move upward, the first driving assembly 40 is used to drive the first limiting assembly 30 to be removed from the side of the second limiting assembly 50 so that the steel cage can be transformed from a horizontal posture to a vertical posture. The second driving assembly 60 is installed on the side wall of the bracket 10. After the steel cage is transformed from a horizontal posture to a vertical posture, the second driving assembly 60 is used to drive the first limiting assembly 30 to move back to the side of the second limiting assembly 50. The first limiting assembly 30 and the second limiting assembly 50 are respectively defined on both sides of the steel cage.

[0039] When the steel cage needs to be hoisted, the lifting assembly 20 can be used to drive the steel cage placed flat on the ground to move horizontally upward along one side of the bracket 10. When the steel cage moves to a certain height, the first driving assembly 40 drives the first limiting assembly 30 to be removed from the side of the second limiting assembly 50. Then the steel cage acts on the second limiting assembly 50 to rotate the steel cage under force until the steel cage changes from a horizontal posture to a vertical posture. The second driving assembly 60 drives the first limiting assembly 30 to move back to the side of the second limiting assembly 50. At this time, the first limiting assembly 30 and the second limiting assembly 50 are respectively limited on the opposite sides of the steel cage to ensure that the steel cage is stably in a vertical posture. The vertical steel cage is driven to move by the bracket 10 to transfer the steel cage to the top of the pile hole on the ground. Then the lifting assembly 20 drives the steel cage to move downward. Through the restrictions of the first limiting assembly 30 and the second limiting assembly 50, the vertical steel cage is stably hoisted into the pile hole to complete the hoisting operation of the steel cage.

[0040] See also Figure 1In one embodiment, the second limiting assembly 50 includes a second limiting roller 501, one end of which is rotatably connected to the side wall of the bracket 10, and the first limiting assembly 30 includes a first limiting roller 301, one end of which passes through the bracket 10 and extends to the side of the second limiting roller 501. When the steel cage moves to the bottom of the second limiting roller 501, the first driving assembly 40 is used to drive the first limiting roller 301 to move in a direction perpendicular to the bracket 10, so that the first limiting roller 301 is removed from the side of the second limiting roller 501. When the steel cage acts on the second limiting roller 501 and changes from a horizontal posture to a vertical posture, the second driving assembly 60 is used to drive the first limiting roller 301 to move in the opposite direction perpendicular to the bracket 10, so that the first limiting roller 301 moves back to the side of the second limiting roller 501.

[0041] The lifting assembly 20 drives the steel cage to move upward. When the steel cage moves to a certain position below the second limiting roller 501, the first driving assembly 40 drives the first limiting roller 301 to move in a direction perpendicular to the bracket 10, so that the first limiting roller 301 is removed from the side of the second limiting roller 501. Then the steel cage acts on the second limiting roller 501. With the continued upward movement of the steel cage, the second limiting roller 501 can push the steel cage to rotate, so that the horizontal steel cage rotates to a vertical position. Then the second driving assembly 60 drives the first limiting roller 301 to move in the opposite direction perpendicular to the bracket 10, so that the first limiting roller 301 moves back to the side of the second limiting roller 501. The first limiting roller 301 and the second limiting roller 501 are respectively limited to the opposite sides of the vertical steel cage, so that the steel cage can be smoothly hoisted into the ground pile hole later.

[0042] See also Figure 2 、 Figure 3 and Figure 4In one embodiment, a first arc-shaped chute 102 and a second arc-shaped chute 103 are provided on the side wall of the bracket 10. The first driving assembly 40 includes a push rod 402, a limiting column 404 and a driving circular plate 405. The driving circular plate 405 is rotatably arranged on one side of the bracket 10. One end of the push rod 402 is connected to an eccentric position on one side of the driving circular plate 405, and the other end passes through the bracket 10 from the second arc-shaped chute 103 and extends to the bottom of the second limiting roller 501. One side of the limiting column 404 is provided with Inclined surface 407, the first limiting roller 301 passes through the driving circular plate 405 from the eccentric position of the driving circular plate 405, one end of the first limiting roller 301 is connected to the inclined surface 407 on one side of the limiting column 404 through the spherical protrusion 306, and the other end passes through the bracket 10 from the first arc-shaped slide groove 102 and extends to the right side of the second limiting roller 501. A baffle 305 is also provided on the side wall of the first limiting roller 301, and the baffle 305 is connected to the driving circular plate 405 through an elastic member 304.

[0043] When the steel cage moves to the bottom of the second limiting roller 501, it can act on the push rod 402, thereby driving the push rod 402 to slide along the second arc-shaped slide groove 103. When the push rod 402 slides, it can drive the driving circular plate 405 to rotate, thereby driving the first limiting roller 301 to slide along the first arc-shaped slide groove 102. During the sliding process of the first limiting roller 301, it can drive the spherical protrusion 306 to slide in contact with the inclined surface 407, and cooperate with the elastic member 304 to drive the support effect, thereby driving the first limiting roller 301 to move in a direction perpendicular to the bracket 10, so that the first limiting roller 301 is removed from the right side of the second limiting roller 50, so that when the steel cage acts on the second limiting roller 501, the steel cage can rotate smoothly, ensuring that the steel cage can be transformed from a horizontal posture to a vertical posture.

[0044] See also Figure 2 In one embodiment, a first support plate 401 is fixedly provided on one side of the bracket 10, a second support plate 403 is fixedly provided on the end of the first support plate 401 away from the bracket 10, and the limiting column 404 is fixedly installed on one side of the second support plate 403.

[0045] See also Figure 3 In one embodiment, the center position of one side of the driving circular plate 405 is rotatably connected to the side wall of the bracket 10 through a rotating rod 406. When the steel cage is changed from a horizontal posture to a vertical posture, the second driving assembly 60 is used to drive the first limiting roller 301 of the driving circular plate 405 to move in the opposite direction perpendicular to the bracket 10, so as to move the first limiting roller 301 back to the side of the second limiting roller 501 to achieve the limitation of the steel cage.

[0046] In one embodiment, the second driving component 60 can be a torsion spring or a scroll spring, which is not limited here. When the steel cage acts on the push rod 402 to drive the driving circular plate 405 to rotate, the torsion spring or the scroll spring is twisted. When the steel cage acts on the second limiting roller 501 to rotate, the elastic member 304 provides elastic support to the first limiting roller 301 to drive the spherical protrusion 306 to slide against the inclined surface 407, so that the first limiting roller 301 slides along the first arc-shaped slide groove 102. It can also move perpendicular to the bracket 10, so that the first limiting roller 301 is removed from the right side of the second limiting roller 501. When the steel cage is transformed into a vertical posture, the effect of the steel cage on the push rod 402 is released. At this time, the torsion spring or the scroll spring drives the driving circular plate 405 to rotate in the opposite direction, and the spherical protrusion 306 slides in the opposite direction along the inclined surface 407. The inclined surface 407 pushes the spherical protrusion 306, thereby driving the first limiting roller 301 to move in the opposite direction perpendicular to the bracket 10 to limit the steel cage in the vertical posture.

[0047] In one embodiment, the elastic member 304 may be a spring or a metal spring, which is not limited here.

[0048] See also Figure 2 In one embodiment, a sleeve 303 is rotatably sleeved on one end of the first limiting roller 301 away from the spherical protrusion 306, and a first groove 302 is opened on the circumferential side wall of the sleeve 303, and a second groove 502 is opened on the circumferential side wall of the second limiting roller 501.

[0049] When the lifting assembly 20 hoists the steel cage into the ground pile hole, through the friction between the steel cage and the sleeve 302 and the second limiting roller 501, the sleeve 302 rotates compared to the first limiting roller 301, and the second limiting roller 501 rotates compared to the bracket 10. Through the setting of the first groove 302 and the second groove 502, the stirrups of the steel cage can adaptively extend into the first groove 302 and the second groove 502 during the downward movement of the steel cage, thereby ensuring the smooth movement of the steel cage.

[0050] See also Figure 2 In one embodiment, a base 105 is fixedly provided at the bottom of the bracket 10, and a plurality of casters 101 are provided on the side of the base 105 away from the bracket 10 to facilitate the flexible movement of the bracket 10, so as to transfer the steel cage to the top of the ground pile hole for lifting the steel cage. The bracket 10 and the base 105 are connected by a triangular plate 104 to enhance the stability of the bracket 10.

[0051] In one embodiment, the lifting assembly 20 includes an electric hoist (not shown in the figure) on the top of the bracket 10 and a cable connected to the output end of the electric hoist, and the end of the cable away from the electric hoist is connected to the middle part of the steel cage.

[0052] The electric hoist drives the cable to be reeled in, thereby driving the steel cage to move upward along one side of the bracket 10 to lift the steel cage. When the bracket 10 transfers the steel cage to above the ground pile hole, the electric hoist drives the cable to be unreeled, thereby hoisting the steel cage into the ground pile hole.

[0053] In the embodiment of the present invention, when the steel cage needs to be hoisted, the lifting assembly 20 can be used to drive the steel cage placed flat on the ground to move horizontally upward along one side of the bracket 10. When the steel cage moves to a certain height, the first driving assembly 40 drives the first limiting assembly 30 to be removed from the side of the second limiting assembly 50. Then the steel cage acts on the second limiting assembly 50 to force the steel cage to rotate until the steel cage changes from a horizontal posture to a vertical posture. The second driving assembly 60 drives the first limiting assembly 30 to move back to the side of the second limiting assembly 50. At this time, the first limiting assembly 30 and the second limiting assembly 50 are respectively limited to the opposite sides of the steel cage to ensure that the steel cage is stably in a vertical posture. The steel cage in the vertical posture is driven to move by the bracket 10. The steel cage is transferred to above the ground pile hole, and then the lifting component 20 drives the steel cage to move downward. Through the restrictions of the first limit component 30 and the second limit component 50, the vertical steel cage is stably hoisted into the pile hole to complete the hoisting operation of the steel cage. Compared with the existing technology, through the cooperation of the lifting component 20, the first limit component 30, the first drive component 40, the second limit component 50 and the second drive component 60, the steel cage can be automatically adjusted to a vertical posture during the lifting process of the steel cage, and when the steel cage is subsequently hoisted into the ground pile hole, it can provide a guiding effect for the steel cage, ensuring that the steel cage stably enters the pile hole without colliding with the inner wall of the pile hole, thereby improving the safety and convenience of the steel cage hoisting process.

[0054] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of this patent.
