Description

Technical Field

[0001] This utility model relates to the field of roll welding machine technology, and in particular to a high-efficiency rebar threading device for concrete pile rebar cages. Background Technology

[0002] The high-efficiency rebar threading equipment for concrete pile rebar cages mainly refers to automated mechanical equipment used to quickly and accurately complete the assembly of the main rebar and stirrups of the rebar cage. Its core function is to improve the processing efficiency and quality of rebar cages. The rebar cage welding machine is a machine that spirally winds steel wire around multiple rebars and welds them together. The rebar cage welding machine can connect multiple rebars into a rigid frame, and concrete can be further poured into the frame. It is widely used in the construction field.

[0003] CN213003243U discloses a variable diameter rebar threading plate for a rebar cage welding machine. This variable diameter rebar threading plate includes a movable plate support, which is slidably mounted on a guide rail and has an installation position formed within it. Support wheels are arranged around the movable plate support. An annular template is positioned at the installation position and presses against the support wheels. The annular template includes an inner ring and an outer ring, connected by several guide posts. Several sleeves are located between adjacent guide posts, and guide sleeves matching the guide posts are arranged on the outer periphery of the sleeves. An adjustment mechanism is also included. The section, used to adjust the position of the sleeve, includes a telescopic rod. The fixed end of the telescopic rod is coaxially fixed to the annular template. The telescopic section is equipped with a fixed plate, and a connecting rod is hinged to the fixed plate. The free end of the connecting rod is hinged to the sleeve. This device is convenient for adjusting the diameter of the reinforcing bar binding and is easy to use. However, the drawback is that the fixed guide sleeve can only accommodate a limited size of reinforcing bars. When the diameter of the guide sleeve and the reinforcing bar do not match, the reinforcing bar will undergo relative displacement in the guide sleeve during the reinforcing bar binding process, resulting in unstable welding and reducing the finished product qualification rate. Therefore, a high-efficiency reinforcing bar binding device for concrete pile reinforcing cages is needed. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-efficiency rebar threading device for concrete pile rebar cages. This device can solve the problem that when the size of the rebar that can be adapted to the fixed guide sleeve is limited, and the diameter of the guide sleeve and the rebar do not match, the rebar will be relatively displaced in the guide sleeve during the threading process, resulting in unstable welding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency rebar threading device for concrete pile rebar cages, comprising a threading disc body and a replaceable guide assembly. The replaceable guide assembly includes a ring, a connecting frame, guide sleeve A, guide sleeve B, guide sleeve C, a first threaded sleeve, and a second threaded sleeve. The ring is fixedly connected inside the threading disc body. There are multiple connecting frames, all of which are fixedly connected to the inner wall of the ring. There are multiple guide sleeves A, which are equidistantly arranged in a circumferential array inside the ring. Each guide sleeve A is slidably connected to the opposite surfaces of two connecting frames. Guide sleeve B is slidably connected inside guide sleeve A, and guide sleeve C is slidably connected inside guide sleeve B. The first threaded sleeve is threaded onto the outer surface of guide sleeve B, and the second threaded sleeve is threaded onto the outer surface of guide sleeve C.

[0006] Preferably, the ring has a fixed plate inside, each connecting frame is fixedly connected to the fixed plate, a hydraulic cylinder is fixedly connected inside the fixed plate, and an adjusting plate is fixedly connected to the surface of the hydraulic cylinder.

[0007] Preferably, the outer surface of the adjusting plate is equidistantly connected to multiple connecting rods in a circumferential array, the number of connecting rods being the same as that of the guide sleeve A, and each connecting rod being rotatably connected to the corresponding guide sleeve A.

[0008] Preferably, each of the guide sleeves A is rotatably connected to two sides with rolling columns, and each connecting frame has a groove on its surface that is adapted to the rolling columns.

[0009] Preferably, the bottom of the rib-threading disc body is slidably connected to a device base, and the top of the device base is fixedly connected to a fixing plate.

[0010] Preferably, a hydraulic cylinder is fixedly connected to the surface of the fixing plate, and the output end of the hydraulic cylinder is fixedly connected to the body of the threading plate.

[0011] Preferably, a telescopic rod is fixedly connected to the surface of the fixing plate, and the telescopic rod is fixedly connected to the opposite surface of the reinforcing plate body and the fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This high-efficiency rebar threading device for concrete piles utilizes a multi-layered nested sliding structure of the guide sleeve. This allows for rapid adjustment of the guide channel according to the rebar specifications, improving the device's adaptability to different rebars, reducing equipment replacement frequency, and solving the problem of limited rebar size compatibility with fixed guide sleeves. When the guide sleeve and rebar diameter do not match, relative displacement of the rebar within the guide sleeve during threading can lead to unstable welding, thus reducing construction costs. The hydraulic cylinder drives the adjusting plate and connecting rod to achieve circumferential array adjustment of the guide sleeve A12, precisely controlling the rebar threading position. Combined with the design of the rolling column and sliding groove, this ensures smooth sliding of the guide sleeve, effectively improving threading accuracy and stability, preventing rebar deviation and jamming, and improving the quality of rebar cage fabrication. The sliding connection between the threading disc body and the device base, along with the auxiliary support of the telescopic rod, allows for flexible adjustment of the working position, enhancing the device's applicability in different construction scenarios and improving overall construction efficiency.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a high-efficiency rebar threading device for concrete pile rebar cages, including a threading disc body 1 and a replaceable guide assembly. The replaceable guide assembly includes a ring 6, a connecting frame 7, a guide sleeve A12, a guide sleeve B15, a guide sleeve C16, a first threaded sleeve 17, and a second threaded sleeve 18. The ring 6 is fixedly connected inside the threading disc body 1. There are multiple connecting frames 7, all of which are fixedly connected to the inner wall of the ring 6. There are multiple guide sleeves A12, which are equidistantly arranged in a circumferential array inside the ring 6. Each guide sleeve A12 is slidably connected to the opposite face of two connecting frames 7. The guide sleeve B15 is slidably connected inside the guide sleeve A12, and the guide sleeve C16 is slidably connected inside the guide sleeve B15. The first threaded sleeve 17 is threaded onto the outer surface of the guide sleeve B15, and the second threaded sleeve 18 is threaded onto the outer surface of the guide sleeve C16.

[0026] Furthermore, the inner part of the ring 6 is provided with a fixed plate 8, and each connecting frame 7 is fixedly connected to the fixed plate 8. A hydraulic cylinder 9 is fixedly connected inside the fixed plate 8, and an adjusting plate 10 is fixedly connected to the surface of the hydraulic cylinder 9. Multiple connecting rods 11 are equidistantly connected to the outer surface of the adjusting plate 10 in a circumferential array. The number of connecting rods 11 is the same as that of the guide sleeve A12. Each connecting rod 11 is rotatably connected to the corresponding guide sleeve A12. Rolling columns 14 are rotatably connected to both sides of each guide sleeve A12. Each connecting frame 7 has a sliding groove 13 adapted to the rolling column 14 on its surface. The bottom of the rib-piercing plate body 1 is slidably connected to the device base 2. The top of the device base 2 is fixedly connected to the fixed plate 3. A hydraulic cylinder 4 is fixedly connected to the surface of the fixed plate 3. The output end of the hydraulic cylinder 4 is fixedly connected to the rib-piercing plate body 1. A telescopic rod 5 is fixedly connected to the surface of the fixed plate 3. The telescopic rod 5 is fixedly connected to the opposite surface of the rib-piercing plate body 1 and the fixed plate 3.

[0027] Furthermore, when the high-efficiency rebar threading equipment for concrete pile rebar cages is in operation, the hydraulic cylinder 4 drives the threading disc body 1 to slide on the device base 2, adjusting the working position of the equipment. The hydraulic cylinder 9 is then activated, which pushes the adjusting plate 10 to move, causing the connecting rod 11 of the circumferential array to rotate. This allows the guide sleeve A12 to slide smoothly within the sliding groove 13 of the connecting frame 7 via the rolling of the rolling column 14, thereby adjusting the position of the guide sleeve A12 and controlling the synchronous contraction and expansion of the rebar cage diameter. The guide sleeves B15 and C16 can slide within the guide sleeves A12 and B15 respectively, and are fixed by the first threaded sleeve 17 and the second threaded sleeve 18. Different sizes of guide sleeves can be installed according to the actual situation to adapt to the threading requirements of different specifications of rebar. During the threading process, the rebar smoothly passes through the rebar cage along the path of the guide sleeve, achieving efficient threading operation.

[0028] Furthermore, the multi-layered nested sliding structure of the guide sleeve allows for rapid adjustment of the guide channel according to the specifications of the reinforcing bars, improving the equipment's adaptability to different reinforcing bars, reducing equipment replacement frequency, and solving the problem of limited reinforcing bar size adaptability of fixed guide sleeves. When the guide sleeve and the diameter of the reinforcing bar do not match, the relative displacement of the reinforcing bar in the guide sleeve during the threading process leads to unstable welding, thus reducing construction costs. The hydraulic cylinder drives the adjusting plate and connecting rod to achieve circumferential array adjustment of the guide sleeve A12, which can accurately control the reinforcing bar threading position. Combined with the design of the rolling column and the slide groove, it ensures smooth sliding of the guide sleeve, effectively improving the threading accuracy and stability, avoiding reinforcing bar deviation and jamming, and improving the quality of reinforcing bar cage fabrication. The sliding connection between the threading disc body and the device base, as well as the auxiliary support of the telescopic rod, allows the equipment to flexibly adjust its working position, enhancing the applicability of the equipment in different construction scenarios and improving overall construction efficiency.
