Description

Technical Field

[0001] This utility model relates to the field of straightening and length-cutting technology, and in particular to a straightening and length-cutting device for processing ring-shaped concrete poles. Background Technology

[0002] With the construction and development of infrastructure such as power and communications, concrete poles are widely used as important support materials in these industries. The processing of ring-shaped concrete poles, especially during straightening and length-cutting, requires high-precision and high-efficiency equipment to ensure the quality of the poles. However, traditional processing equipment often faces problems such as low processing accuracy, low production efficiency, and safety hazards during processing. Therefore, developing a ring-shaped concrete pole processing equipment that can improve processing accuracy and optimize the production process has become particularly important.

[0003] Currently, most straightening and cutting equipment for ring-shaped concrete poles employs hydraulic drive systems and mechanical structures for straightening, length setting, and cutting operations. Its core principle is typically based on hydraulic cylinders that clamp and stabilize the pole by pushing a work platform or support structure. During operation, the pole advances along mechanical guide rails, and the height of the cutting blades is precisely adjusted via a hydraulic system to ensure the pole is cut at the designated position. Furthermore, the length setting is controlled by precision measuring devices to ensure the pole length meets design requirements. Operation primarily relies on manual loading, and the equipment is connected to the pole via mechanical components, ensuring the pole is securely positioned and handled during processing.

[0004] However, existing straightening and length-setting shearing equipment often faces a serious problem: due to the lack of an effective clamping device, the pole is prone to positional shift or wobbling during the shearing process. Especially when the pole is long or irregularly shaped, the equipment cannot provide sufficient stability, resulting in inaccurate alignment of the pole during processing and affecting shearing precision. This not only affects processing quality but also leads to material waste and reduced production efficiency. Therefore, a straightening and length-setting shearing equipment for processing ring-shaped concrete poles is proposed to solve these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a straightening and length-fixing shearing device for processing ring-shaped concrete poles, aiming to improve the problem that the existing technology does not have a device to clamp the pole, and the pole will shift or shake during the shearing process, resulting in reduced processing accuracy.

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

[0007] A straightening and length-setting shearing device for processing ring-shaped concrete poles includes a support frame. A motor screw drive structure is fixedly connected to the side wall of the support frame. A cutting machine is slidably connected to the outer wall of the motor screw drive structure. A sliding plate is slidably connected to the outer wall of the motor screw drive structure. A third rotating plate is fixedly connected to the top of the sliding plate. A clamping assembly is provided on the top of the sliding plate.

[0008] The clamping assembly includes a double-headed hydraulic cylinder. The bottom of the double-headed hydraulic cylinder is fixedly connected to the top of the sliding plate. The output ends of the double-headed hydraulic cylinder are each fixedly connected to a first support plate. A connecting frame is fixedly connected to the top of the first support plate. A clamping plate is fixedly connected to the top of the connecting frame. A limit component is provided at the bottom of the connecting frame.

[0009] Furthermore, the limiting component includes a slider, the top of which is fixedly connected to the bottom of the connecting frame, the top of which is fixedly connected to a slide rail, and the slider is slidably connected to the outer wall of the slide rail.

[0010] Furthermore, a support frame is fixedly connected to the top of the bracket, and multiple modulation rollers are rotatably connected to the inner wall of the support frame. A synchronous belt drive structure is fixedly connected to the bottom of the bracket, and a rotating wheel is rotatably connected to the side wall of the synchronous belt drive structure. The side wall of the rotating wheel is rotatably connected to the side wall of the support frame.

[0011] Furthermore, the side wall of the bracket is provided with a feeding plate, a plurality of limiting posts are fixedly connected to the side wall of the feeding plate, a second support plate is fixedly connected to the side wall of the feeding plate, a first connecting plate is fixedly connected to the bottom of the second support plate, and a second connecting plate is rotatably connected to the side wall of the first connecting plate.

[0012] Furthermore, a first hydraulic cylinder is fixedly connected to the side wall of the second connecting plate, and a slotted plate is fixedly connected to the output end of the first hydraulic cylinder. A first rotating plate is rotatably connected to the inner wall of the slotted plate.

[0013] Furthermore, a second rotating plate is rotatably connected to the inner wall of the first rotating plate, and a third rotating plate is rotatably connected to the other side of the second rotating plate.

[0014] Furthermore, a limiting block is slidably connected to the outer wall of the third rotating plate, the bottom of the limiting block is fixedly connected to the top of the feeding plate, and a baffle is fixedly connected to one side of the third rotating plate.

[0015] Furthermore, the side wall of the baffle is slidably connected to the inner wall of the feeding plate, and the side wall of the second support plate is fixedly connected to a third connecting plate, the inner wall of the third connecting plate being rotatably connected to the side wall of the first rotating plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the first support plate is moved by a double-headed hydraulic cylinder. The movement of the first support plate brings together the top connecting frame and clamping plate, achieving the effect of clamping the pole. This solves the problem that without a clamping device, the pole will shift or shake during the shearing process, resulting in reduced processing accuracy. This improves the stability of the straightening and length-setting shearing equipment for pole processing.

[0018] 2. In this utility model, the empty slot plate is driven to move by the first hydraulic cylinder. Then, the movement of the empty slot plate causes the first rotating plate on the inner wall to rotate. At the same time, the first rotating plate rotates on the inner wall of the third connecting plate. Next, during the process of the first rotating plate being subjected to force, the second and third rotating plates are driven to move. The third rotating plate slides on the inner wall of the limiting block. Then, during the process of the third rotating plate being subjected to force, the baffle at one end is driven to move, thus achieving the effect of automatic feeding. This solves the problem that manual feeding requires additional manpower, which leads to a decrease in production efficiency and improves the practicality of the straightening and length-cutting equipment for pole processing.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a straightening and length-setting shearing device for processing ring-shaped concrete poles, including a support 1. The support 1 supports the overall structure of the device and provides an installation foundation for each component, thereby ensuring the stability of the device during operation and ensuring the smooth progress of processing. A motor screw transmission structure 4 is fixedly connected to the side wall of the support 1. The motor screw transmission structure 4 is mainly composed of a motor, screw, nut, support seat and guide device, etc., which is the prior art and will not be described in detail here. The motor screw transmission structure 4 slides in conjunction with the cutting machine 3 and the sliding plate 5, so that the cutting machine 3 can adjust the cutting position and the sliding plate 5 can drive the clamping assembly to move to the bottom of the pole, achieving the effect of flexibly adjusting the processing position. The cutting machine 3 is slidably connected to the outer wall of the motor screw transmission structure 4, and the sliding plate 5 is slidably connected to the outer wall of the motor screw transmission structure 4. A third rotating plate 26 is fixedly connected to the top of the sliding plate 5, and a clamping assembly is provided on the top of the sliding plate 5.

[0028] The clamping assembly includes a double-headed hydraulic cylinder 20, the bottom of which is fixedly connected to the top of the sliding plate 5. The output ends of the double-headed hydraulic cylinder 20 are each fixedly connected to a first support plate 21. A connecting frame 24 is fixedly connected to the top of the first support plate 21. A clamping plate 25 is fixedly connected to the top of the connecting frame 24. A limit component is provided at the bottom of the connecting frame 24, which includes a slider 22. The slider 22 slides in conjunction with the slide rail 23, thereby guiding and limiting the movement of the connecting frame 24, ensuring that the clamping plate 25 can accurately converge to clamp the pole, achieving a stable clamping effect. The top of the slider 22 is fixedly connected to the bottom of the connecting frame 24, and the top of the sliding plate 5 is fixedly connected to the slide rail 23. The slider 22 is internally slidably connected to the outer wall of the slide rail 23.

[0029] Specifically, after the equipment is started, the synchronous belt drive structure 10 first drives the rotating wheel 9 to rotate, which in turn drives the modulation roller 8 to rotate, straightening the pole and conveying it to the processing area. When the pole reaches the designated position, the sliding plate 5 slides along the motor screw drive structure 4 to the bottom of the pole, the double-headed hydraulic cylinder 20 is activated, pushing the first support plates 21 on both sides to move towards each other, ensuring that the pole is firmly clamped. The connecting frame 24 moves synchronously with the support plates 21, and the bottom slider 22 slides along the slide rail 23 to maintain the stability of the equipment and prevent structural displacement. After the clamping plate 25 firmly clamps the pole, the cutting machine 3 slides to the appropriate position to complete the fixed-length cutting task, ensuring accurate cutting of the pole and stability during the processing, effectively improving production efficiency and ensuring the processing accuracy of the pole.

[0030] Reference Figure 1 and Figure 5A support frame 2 is fixedly connected to the top of the support frame 1. The support frame 2 rotates in conjunction with the modulation roller 8 to straighten the pole, ensuring it remains straight before entering the shearing stage, providing a good foundation for subsequent length shearing. Multiple modulation rollers 8 are rotatably connected to the inner wall of the support frame 2. A synchronous belt drive structure 10 is fixedly connected to the bottom of the support frame 1. The synchronous belt drive structure 10 mainly consists of a motor, pulley, synchronous belt, tensioning device, and support structure, which is existing technology and will not be described in detail here. A rotating wheel 9 is rotatably connected to the side wall of the synchronous belt drive structure 10. The side wall of the rotating wheel 9 is rotatably connected to the side wall of the support frame 2. A feeding plate 7 is provided on the side wall of the support frame 1. Multiple limiting posts 6 are fixedly connected to the side wall of the feeding plate 7. A second support plate 27 is fixedly connected to the side wall of the feeding plate 7. A first connecting plate 11 is fixedly connected to the bottom of the second support plate 27. A second connecting plate 12 is rotatably connected to the side wall of the first connecting plate 11. A first hydraulic cylinder 13 is fixedly connected to the side wall of the second connecting plate 12. The first hydraulic cylinder 13 works in conjunction with the empty slot plate 14 and the first rotating... Plate 15, the second rotating plate 17, and the third rotating plate 26 move, thereby causing the baffle 19 to slide within the loading plate 7, achieving the effect of automatically pushing the electric rod to move towards the processing area. The output end of the first hydraulic cylinder 13 is fixedly connected to a slotted plate 14. The inner wall of the slotted plate 14 is rotatably connected to the first rotating plate 15. The inner wall of the first rotating plate 15 is rotatably connected to the second rotating plate 17. The other side of the second rotating plate 17 is rotatably connected to the third rotating plate 26. The outer wall of the third rotating plate 26 is slidably connected to a limit block 18. The positioning block 18 slides in conjunction with the third rotating plate 26, thereby limiting the movement trajectory of the third rotating plate 26 and ensuring that the baffle 19 can stably push the electric pole, achieving the effect of precise feeding. The bottom of the positioning block 18 is fixedly connected to the top of the feeding plate 7. The baffle 19 is fixedly connected to one side of the third rotating plate 26. The side wall of the baffle 19 is slidably connected to the inner wall of the feeding plate 7. The side wall of the second support plate 27 is fixedly connected to the third connecting plate 16. The inner wall of the third connecting plate 16 is rotatably connected to the side wall of the first rotating plate 15.

[0031] Specifically, during the loading stage, the electric pole is first placed on the loading plate 7, with the limiting post 6 acting as an initial limit to ensure its stable position. Then, the first hydraulic cylinder 13 is activated, its output pushing the empty slot plate 14 to move. The movement of the empty slot plate 14 causes the first rotating plate 15 to rotate around the connection point of the third connecting plate 16. During the rotation of the first rotating plate 15, the second rotating plate 17 moves synchronously, which in turn pulls the third rotating plate 26 to slide smoothly along the limiting block 18. As the third rotating plate 26 moves, the baffle 19 gradually approaches the loading plate 7 and slides within it. The baffle 19 contacts the electric pole, pushing it towards the processing area, completing the automated loading process. This significantly reduces manual intervention, improves the speed and accuracy of the loading process, and substantially enhances overall processing efficiency. It not only reduces labor costs but also strengthens the stability and continuity of the production line.

[0032] Working principle: When the equipment is running, the synchronous belt drive structure 10 first drives the rotating wheel 9 to rotate. The rotating wheel 9 drives the modulation roller 8 in the support frame 2 to rotate. Under the action of the modulation roller 8, the electric pole is straightened and transported to the processing area. When the electric pole reaches the designated position, the sliding plate 5 slides on the motor screw drive structure 4 to the bottom of the electric pole. The double-headed hydraulic cylinder 20 is started, and its output end pushes the first support plates 21 on both sides to move towards each other. The connecting frame 24 moves synchronously with the first support plates 21. The bottom slider 22 slides along the slide rail 23 to ensure movement stability. Finally, the clamping plates 25 on both sides come together and clamp the electric pole to ensure that the electric pole does not deviate or shake during the cutting process. Then the cutting machine 3 slides on the motor screw drive structure 4 to the appropriate position to complete the fixed-length cutting operation.

[0033] During the loading stage, the electric pole is placed on the loading plate 7, and the limiting post 6 provides initial positioning for the electric pole. The first hydraulic cylinder 13 is activated, and its output end pushes the empty slot plate 14 to move. The empty slot plate 14 drives the first rotating plate 15 to rotate around the connection point of the third connecting plate 16. During the rotation of the first rotating plate 15, it drives the second rotating plate 17 to move. The second rotating plate 17 pulls the third rotating plate 26 to slide along the limiting block 18, so that the baffle 19 on one side of the third rotating plate 26 slides within the loading plate 7. The baffle 19 pushes the electric pole to move towards the processing area, realizing automatic loading, reducing manual intervention, and improving overall processing efficiency.
