Description

Technical Field

[0001] This utility model relates to the field of steel cage processing technology, and in particular to a large-diameter steel cage binding device. Background Technology

[0002] In the construction of large concrete structures such as bridge pile foundations and high-rise buildings, the binding quality of large-diameter reinforcing cages directly affects the structural load-bearing capacity. Existing binding devices mainly include three technical solutions:

[0003] The first type is a fixed jig mold, such as a positioning jig that uses a semi-circular steel plate with pre-set slots. The main reinforcement is constrained by the semi-circular slots with a fixed radius. Although this can ensure the binding accuracy of a single diameter steel cage, the slot spacing and depth are fixed values, which cannot adapt to different steel density requirements. The second type is a limited adjustable support structure, such as a cross brace that adjusts the length of the struts by threads, or an internal support device that uses a scale rod and a fixed knob to control the radial dimension. Although it can achieve a diameter adjustment of ±200mm, the number of support points is fixed. When the steel density increases, the insufficient distribution density of support points leads to local instability of the stirrups and causes radial shrinkage deformation. The third type is mechanized binding equipment, such as a CNC rubber roller driven forming machine. It adapts to steel cages of different diameters by adjusting the rubber roller spacing and controls the winding speed of the stirrups. However, its support frame only provides a circumferentially distributed basic support point and cannot dynamically increase the support point density according to the number of main reinforcements, resulting in cumulative errors in the main reinforcement offset when binding high-density steel cages. Utility Model Content

[0004] The purpose of this invention is to provide a large-diameter rebar cage binding device to address the above-mentioned shortcomings, thereby solving the problem that existing rebar cage binding devices cannot be adjusted according to different models and rebar densities.

[0005] This utility model is achieved through the following solution:

The positioning component is equipped with an adjustable-length lifting ring assembly, which can move along the length of the positioning assembly. The transmission component is equipped with an adjustable clamp for fixing the rebar to be bound.

[0007] Based on the structure of the above-mentioned large-diameter steel cage binding device, the first support frame includes a support base, a rotating component, and a rotating belt; the top of the support base is configured as a cavity structure, the rotating component is symmetrically arranged at the top position of the support base, and the rotating belt is sleeved between the two rotating belts.

[0008] Based on the structure of the above-mentioned large-diameter rebar cage binding device, the positioning component includes a support ring, a support sleeve, and a lifting ring. The support ring is a closed circular ring structure. The support sleeve is movably sleeved on the support ring, and multiple support sleeves are provided on the support ring. The support sleeve is provided with a contacting element that is fixed to the support ring. The support sleeve is provided with a threaded hole that mates with the lifting ring. The lifting ring is provided with a threaded rod, and the lifting ring is set in the threaded hole through the threaded rod.

[0009] Based on the structure of the above-mentioned large-diameter rebar cage binding device, the contact element includes a contact head, a contact gripper, and a contact connecting rod. The support sleeve is provided with a threaded hole that mates with the support connecting rod. The contact connecting rod is connected to the contact gripper and the contact head respectively, and the contact connecting rod is provided with an external thread.

[0010] Based on the structure of the large-diameter rebar cage binding device described above, the transmission assembly includes a first transmission shaft, a second transmission shaft, a universal joint, and a connector. The connector is located at the end of the first transmission shaft, and the end of the first transmission shaft away from the connector has a insertion cavity. The size of the end of the second transmission shaft is adapted to the size of the insertion cavity. The first transmission shaft and the second transmission shaft are connected by a socket joint through the insertion cavity. The universal joint is located in the second transmission shaft. The connector is used to connect with an adjustable clamp.

[0011] Based on the structure of the above-mentioned large-diameter steel cage binding device, the power component includes a rotating motor and a motor support. The rotating motor is mounted on the motor support, and a flange is provided on the output part of the rotating motor, which is connected to the second drive shaft through the flange.

[0012] Based on the structure of the above-mentioned large-diameter rebar cage binding device, the adjustable clamping includes a support plate, a sliding member, and a clamping member; the support plate is provided with a connecting hole that cooperates with an external rotating mechanism; the sliding member is sleeved on both sides of the support plate and can move along the length direction of the support plate; the clamping member is disposed on the sliding member and can move closer to or away from the support plate.

[0013] Based on the structure of the above-mentioned large-diameter steel cage binding device, the support plate is a cuboid structure, that is, the cross section of the support body and the sliding member is a rectangular structure; the sliding member is provided with a rectangular cavity structure that cooperates with the support body.

[0014] Based on the structure of the above-mentioned large-diameter rebar cage binding device, the sliding member includes a sliding sleeve and a second support frame. The second support frame is symmetrically arranged on both sides of the sliding sleeve at the center position along the length direction of the sliding sleeve, and the second support frame is provided with a first threaded hole that cooperates with the clamping member.

[0015] Based on the structure of the above-mentioned large-diameter steel cage binding device, the second support frame is an L-shaped structure, which includes a first connecting plate and a second connecting plate; the first connecting plate is arranged perpendicular to the end face of the sliding member, the second connecting plate is arranged perpendicularly on the end of the first connecting plate away from the sliding member, and the second connecting plate is arranged parallel to the sliding member.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] 1. In this solution, the reinforcing bars to be bundled are connected to the positioning assembly via a lifting ring assembly. The first support frame supports the entire reinforcing bar system. The power assembly is fixed to the reinforcing bars via a transmission assembly. When the power assembly operates, the transmission assembly drives the reinforcing bar system supported by the first support frame to rotate, facilitating manual bundling of the reinforcing cage. This solution includes an adjustable-length lifting ring assembly, which can be adjusted according to the size of the reinforcing cage. The lifting ring assembly can also move along the length of the positioning assembly, allowing for positional adjustment based on the density of the reinforcing cage, ensuring a matching position. Adjustable clamps are installed on the transmission assembly to fix the ends of reinforcing cages of different sizes, achieving stable power output.

[0018] 2. This solution uses a sliding component that can move along the length of the support plate to fix steel cages of different diameters. By adjusting a single clamp, steel cages of different sizes can be fixed without changing the clamping component. This also saves adjustment time after disassembly and reduces the overall time required to replace steel cages of different large diameters.

[0019] 3. This solution avoids rigid contact between the reinforcing bar and the clamping seat by incorporating a flexible layer on the contact plate, thus preventing damage to the anti-corrosion coating on the reinforcing bar surface. Simultaneously, designing the contact plate as an arc-shaped structure increases the contact area with the reinforcing bar, making the clamping process more stable. Since the clamped reinforcing bar needs to be rotated, the arc-shaped structure of the contact plate can restrict the forward or reverse rotation of the reinforcing bar during rotation.

[0032] Example 1

[0033] like Figures 1-7 As shown, this utility model provides a technical solution:

[0034] A large-diameter rebar cage binding device includes, but is not limited to, a first support frame 100, a positioning component 200, a transmission component 300, and a power component 400. At least two first support frames 100 are provided along the length of the rebar cage 500 to be fixed. The power component 400 is positioned opposite the first support frame 100. The output end of the power component 400 is connected to the positioning component 200 through the transmission component 300. The positioning component 200 is connected to the rebar to be bound. An adjustable lifting ring 203 is provided on the positioning component 200. The lifting ring 203 can move along the length of the positioning component. An adjustable clamp 600 for fixing the rebar to be bound is provided on the transmission component 300.

[0035] Based on the above structure, the reinforcing bars to be bundled are connected to the positioning component 200 via the lifting ring 203 assembly. The first support frame 100 is used to support the entire reinforcing bar system to be bundled. The power component 400 is fixed to the reinforcing bars to be bundled via the transmission component 300. Under the action of the power component 400, the transmission component 300 drives the reinforcing bar system supported by the first support frame 100 to rotate, facilitating manual bundling of the reinforcing bar cage 500. This solution is equipped with an adjustable lifting ring 203 assembly, which can be adjusted according to the size of the reinforcing bar cage 500 to be bundled. At the same time, the lifting ring 203 assembly can move along the length direction of the positioning component 200. The position of the lifting ring 203 assembly can be moved according to the density of the reinforcing bar cage 500 to be bundled, so as to achieve matching of the position of the lifting ring 203 assembly. An adjustable clamp 600 is set on the transmission component 300, which can fix the ends of reinforcing bar cages 500 of different sizes and achieve stable power output.

[0036] Based on the above structure, the first support frame 100 may include a support base 101, a rotating assembly 102 and a rotating belt 103; the top of the support base 101 is configured as a cavity structure, the rotating assembly 102 is symmetrically arranged at the top position of the support base 101, and the rotating belt 103 is sleeved between the two rotating belts 103.

[0037] Based on the above structure, the rotating belt 103 in this solution is a component used to support the steel cage 500 to be bundled. By supporting it with the flexible rotating belt 103, damage to the surface of the steel bars can be avoided during rotation. The rotating assembly 102 does not require a power end; it only rotates under force. When the steel cage 500 is driven to rotate, the rotating assembly 102 achieves rotation under force.

[0038] As an example, the positioning component 200 may include a support ring 201, a support sleeve 202, and a lifting ring 203. The support ring 201 is a closed circular ring structure. The support sleeve 202 is movably sleeved on the support ring 201, and multiple support sleeves are provided on the support ring 201. The support sleeve 202 is provided with abutting members 204 that are fixed to the support ring 201. The support sleeve 202 is provided with threaded holes that mate with the lifting ring 203. The lifting ring 203 is provided with threaded rods, and the lifting ring 203 is set in the threaded holes through the threaded rods.

[0039] Based on the above structure, this solution uses multiple support sleeves 202, which can be selected according to the specific number of steel bars in the steel cage 500 to be fixed on site. The support sleeves 202 can be moved to a predetermined position to cooperate with the steel bars. The support sleeves 202 lock their position by contact. The lifting ring 203 is connected to the threaded hole through a threaded rod. The position of the lifting ring 203 relative to the support ring 201 can be adjusted by rotation. It can be adapted to the size of different models of steel cages 500. Ultimately, this solution can fix steel cages 500 of different sizes and steel bar densities, making the solution more adaptable.

[0040] As an example, the abutment 204 may include an abutment head 205, an abutment gripper 206, and an abutment link 207. The support sleeve 202 is provided with a threaded hole that mates with the support link. The abutment link 207 is connected to the abutment gripper 206 and the abutment head 205 respectively, and the abutment link 207 is provided with an external thread.

[0041] Based on the above structure, the depth of the abutment head 205 can be adjusted by rotating the abutment head 205. When locking is required, the abutment head 205 is brought into contact with the support ring 201. When the support sleeve 202 needs to be moved, the abutment head 205 is spaced apart from the support ring 201.

[0042] As an example, the transmission assembly 300 may include a first transmission shaft 301, a second transmission shaft 302, a universal joint 303, and a connector 304; the connector 304 is disposed at the end of the first transmission shaft 301, and the end of the first transmission shaft away from the connector 304 is provided with a insertion cavity, the size of the end of the second transmission shaft 302 is adapted to the size of the insertion cavity, and the first transmission shaft 301 and the second transmission shaft are connected by a socket through the insertion cavity; the universal joint 303 is disposed in the second transmission shaft 302; the connector 304 is used to connect with the adjustable clamp 600.

[0043] Based on the above structure, in this solution, by inserting the first drive shaft 301 and the second drive shaft 302 together, it is convenient to fix the first drive shaft 301 to the adjustable clamp 600 and then insert it to the second drive shaft 302, making the whole connection method simpler. At the same time, a universal joint 303 is set in the second drive shaft 302 to realize torque transmission at different positions and ensure the stability of power output.

[0044] As an example, the power assembly 400 may include a rotary motor 401 and a motor support 402. The rotary motor 401 is mounted on the motor support 402, and a flange is provided on the output part of the rotary motor 401, which is connected to the second drive shaft 302.

[0045] Based on the above structure, in this solution, the rotating motor 401 provides power to the entire steel cage 500, and the construction workers bind the steel cage 500 to be fixed while the steel cage 500 is rotating.

[0046] As an example, the adjustable clamp includes a support plate 1, a sliding member 2, and a clamping member 3; the support plate 1 is provided with a connecting hole 4 that cooperates with an external rotating mechanism; the sliding member 2 is sleeved on both sides of the support plate 1 and can move along the length direction of the support plate 1; the clamping member 3 is provided on the sliding member 2 and can move closer to or away from the support plate 1.

[0047] Based on the above structure, this solution can fix steel cages of different diameters by setting a sliding member 2 that can move along the length of the support plate 1. The steel cages of different sizes can be fixed by adjusting one clamp, without the need to replace the clamping member. It also saves the adjustment time after disassembly and reduces the time required to replace steel cages of different models with large diameters.

[0048] As an example, the support plate 1 is a rectangular parallelepiped structure, that is, the cross section of the support body and the sliding member 2 is a rectangular structure; the sliding member 2 is provided with a rectangular cavity structure that cooperates with the support body.

[0049] Based on the above structure, by setting the support plate 1 as a cuboid structure and the sliding member 2 as a rectangular cavity structure, the sliding member 2 can be prevented from rotating when the support body is driven to rotate. Since it is a rectangular cavity structure, the sliding member 2 can only move along the length direction of the support plate 1, avoiding relative rotation between the sliding member 2 and the support plate 1, thus ensuring the stability of the support plate 1 and the sliding member 2 in fixing the steel bars.

[0050] As an example, the sliding member 2 may include a sliding sleeve 21 and a second support frame 22. The second support frame 22 is symmetrically arranged on both sides of the sliding sleeve 21 at the center position along the length direction of the sliding sleeve 21. A first threaded hole 23 that cooperates with the clamping member 3 is provided on the second support frame 22.

[0051] The second support frame 22 has an overall L-shaped structure, specifically including a first connecting plate 221 and a second connecting plate 222; the first connecting plate 221 is arranged perpendicular to the end face of the slider 2, and the second connecting plate 222 is arranged perpendicularly on the end of the first connecting plate 221 away from the slider 2, and the second connecting plate 222 is arranged parallel to the slider 2.

[0052] Based on the above structure, by setting a second support frame 22 on both sides of the sliding sleeve 21, the steel bars can be limited simultaneously on both sides of the sliding sleeve 21. Limiting on both sides can increase the number of steel bars clamped, making it more stable during rotation, and can also achieve stable clamping in both forward and reverse rotation.

[0053] As an example, the clamping component 3 may include a threaded rod 31, a rotating handle 32, a guide rod 33, a rotating bearing 34, and a clamping seat 35; the threaded rod 31 is disposed in the threaded hole of the second support frame 22, the guide rod 33 is disposed on the side of the second connecting plate 222 near the support plate 1 and extends a predetermined distance in the direction of the support plate 1, the rotating bearing 34 is disposed on the clamping seat 35, the clamping seat 35 is also provided with a through hole that mates with the guide rod 33, and the rotating handle 32 is disposed on the threaded rod 31.

[0054] Based on the above structure, since the end of the threaded rod 31 is connected to the clamping seat 35 through the rotating bearing 34, and the clamping seat 35 is slidably connected to the guide rod 33, the whole structure presents a screw structure. Rotating the threaded rod 31 will drive the clamping seat 35 to move in a predetermined direction. At the same time, the guide can prevent the clamping seat 35 from rotating, so that it can only move in the direction of approaching or moving away from the support plate 1, and finally achieve the clamping of the steel bar. Since it can be telescopically adjusted, it can quickly adapt to different types of steel bars.

[0055] As an example, the clamping seat 35 may include a support base plate 351 and a contact plate 352; the support base plate 351 is provided with a through hole that mates with the guide rod 33, the rotating bearing 34 is provided on the end face of the support base plate 351 near the second connecting plate 222, and the contact plate 352 is provided on the end face of the support base plate 351 away from the second connecting plate 222.

[0056] The contact plate 352 can be an arc-shaped structure, and a flexible layer 353 is provided on each contact surface between the contact plate 352 and the reinforcing bar.

[0057] Based on the above structure, by providing a flexible layer 353 on the contact plate 352, rigid contact between the reinforcing bar and the clamping seat 35 can be avoided, thus preventing damage to the anti-corrosion layer on the surface of the reinforcing bar. Simultaneously, setting the contact plate 352 to an arc shape increases the contact area with the reinforcing bar, making the clamping process more stable. Since the clamped reinforcing bar needs to be rotated, setting the contact plate 352 to an arc shape allows the two ends of the arc shape to restrict the forward or reverse rotation of the reinforcing bar during rotation.

[0058] As an example, a locking engagement plate 24 is provided on the end face of the first connecting plate 221 away from the guide rod 33. A second threaded hole 25 is provided on the locking engagement plate 24. A locking rod 26 is provided in each threaded hole. An insertion hole 27 that mates with the locking rod 26 is provided on each of the support plates 1. The locking rod 26 is provided with an external thread.

[0059] Based on the above structure, since the support plate 1 will rotate under the action of the driving component, the position may shift during the rotation. Therefore, a locking rod 26 is provided. The locking rod 26 is screwed into the threaded hole of the locking mating plate 24 to achieve stable lifting and lowering. When locking is required, the locking rod 26 is screwed into the insertion hole 27. Locking is achieved by screwing in and out, which can prevent the locking rod 26 from falling off during the rotation.

[0060] As an example, multiple insertion holes 27 are provided along the length of the support plate 1, and the insertion holes 27 are provided on the upper and lower end faces of the support plate 1. The connection holes 4 are provided through the left and right end faces of the support plate 1.

[0061] Based on the above structure, by setting the insertion hole 27 and the connection hole 4 to be on different end faces, the support strength of the support plate 1 can be guaranteed and damage can be avoided during the rotation support process.

[0062] As an example, the connecting hole 4 can be an oblong hole, which facilitates the cooperation between the support plate 1 and the external rotating components, enabling it to move left and right for easy adjustment.

[0063] As an example, a mating plate 28 is provided on the slider 2. The mating plate 28 is made of a flexible material and is provided on the end of the slider 2 away from the locking lever 26.

[0064] Based on the above structure, the mating plate 28 is used to prevent the reinforcing bars from directly contacting the support plate 1. On the one hand, it can prevent the reinforcing bars in the compressed state from causing damage to the insertion hole 27, and on the other hand, it can also prevent the insertion hole 27 from causing damage to the protective layer of the reinforcing bars.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
