Description

Technical Field

[0001] This invention relates to the field of angle steel cutting technology, and in particular to a multi-angle cutting device for power transmission towers. Background Technology

[0002] In the design and manufacture of power transmission towers, they are mainly connected by angle steel, steel plates and bolts. When multiple angle steels intersect, they are prone to spatial interference due to collisions between the angle steel legs, which can cause the components to not fit tightly and affect the structural strength. The traditional solution is to use a corner cutting machine to cut the angle steel legs at the collision points to remove the interference parts and ensure smooth assembly.

[0003] However, existing corner cutting machines have obvious limitations: 1. The cutting angle is limited, and the blade can only move up and down in a fixed direction. The angle is fixed and cannot be flexibly adjusted; 2. The operation is cumbersome. When the angle steel needs to be cut at different angles, the worker needs to repeatedly adjust the direction and position of the angle steel to match the fixed blade. This is not only inefficient, but also prone to inaccurate corner cutting due to human error. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that existing corner cutting machines have a single corner cutting angle and the blade can only move up and down in a fixed direction, and the angle is fixed and cannot be flexibly adjusted. Therefore, a multi-angle corner cutting device for power towers is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-angle cutting device for power transmission towers includes an operating platform. A conveyor for conveying angle steel is provided on one side of the operating platform. An angle adjustment unit is installed on the operating platform via a bracket. The angle adjustment unit includes a support frame slidably mounted on the bracket. An inner frame is assembled inside the support frame. A sectional adjustment component is assembled inside the inner frame. The sectional adjustment component is connected to the cutting component via the base, and the support frame together with the cutting component is moved downward via the first electro-hydraulic rod mounted on the top of the bracket. The inner frame is rotated by a first motor installed on the outer wall of the support frame to control the cutting angle of the cutting assembly; The cutting assembly includes a mounting base rotatably connected to the base, a mounting shaft rotatably connected to the mounting base, a cutting blade being mounted at one end of the mounting shaft, and a fourth motor having its output end connected to the mounting shaft being mounted at one end of the mounting base.

[0006] As a further description of the above technical solution: The sectional adjustment assembly includes multiple positioning seats fixed on the inner frame. A shaft is rotatably connected to each positioning seat through a through hole. A second motor with its output end connected to one of the shafts is mounted on the outer wall of the inner frame.

[0007] As a further description of the above technical solution: Multiple positioning slots are provided at one end of two of the shafts and at both ends of the other shaft. The four positioning slots are distributed in pairs, and a rod is inserted into each pair. A bearing seat is fitted on the outer surface of the rod. A push plate is fixed on each of the two bearing seats. A third electric hydraulic rod connected to the push plate is mounted on both sides of the middle positioning seat through an extension plate.

[0008] As a further description of the above technical solution: A retainer is fixed on the shaft, and the base is inserted into the retainer. A third motor with its output end connected to the top of the mounting base is installed in the middle of the base.

[0009] As a further description of the above technical solution: A second electro-hydraulic rod is fixed to the outer wall of the cage, and one end of the second electro-hydraulic rod is fixed to the base.

[0010] As a further description of the above technical solution: A clamping unit is provided at the edge of the upper surface of the operating table. The clamping unit includes a guide plate fixed to the operating table, and multiple guide plates are distributed in pairs.

[0011] As a further description of the above technical solution: A mounting frame is fixed on the operating table, and a fourth electro-hydraulic rod is mounted on the mounting frame. A horizontal plate is installed at one end of the fourth electro-hydraulic rod, and three positioning posts corresponding to the three sets of guide plates are fixed at the bottom of the horizontal plate.

[0012] As a further description of the above technical solution: The bottom of the operating table is equipped with a waste collection assembly, which includes a guide frame installed on the lower surface of the operating table. The surface of the operating table is provided with a discharge groove corresponding to the inlet end of the guide frame, and a receiving box corresponding to the outlet of the guide frame is provided on one side of the operating table.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: The angle adjustment unit and cutting component enable flexible and diverse angle adjustment. Through the coordinated action of the inner frame, the sectional adjustment component and the cutting component, the combined vertical and horizontal angle adjustment can be achieved. The inner frame can be adjusted vertically by the first motor, and the third motor can drive the mounting base to rotate the cutting blade horizontally to meet the cutting requirements of complex intersection nodes. Meanwhile, the sectional adjustment assembly, through the cooperation of the shaft, insert rod and the third electric hydraulic rod, can individually or in conjunction with multiple cutting assemblies to achieve synchronous processing of multiple angle steels at different angles (15° and multiples of 15°), without the need for individual adjustment, greatly improving adaptability and processing efficiency.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1 - Figure 12 As shown, the present invention provides: A multi-angle corner cutting device for power transmission towers includes an operating platform 10. One side of the operating platform 10 is provided with a conveyor 11 for conveying angle steel. In particular, the conveyor 11 is a roller conveyor, which is a well-known technology. The specific operating principle will not be described in detail here. A clamping unit 40 is provided at the edge of the upper surface of the operating table 10. The clamping unit 40 includes a guide plate 41 fixed on the operating table 10. Multiple guide plates 41 are distributed in pairs. Preferably, the inner sides of three guide plates 41 are rotatably connected to limit posts. The limit posts can provide auxiliary guidance for the angle steel. In particular, the space enclosed by each group of guide plates 41 is funnel-shaped, with the inlet end being larger than the width of the angle steel and the outlet end being equal to the width of the angle steel. At the same time, the guide plates 41 are installed on the operating table 10 by bolts. In actual use, the position of the guide plates 41 can be adjusted in advance according to the width of the angle steel, and part of the guide plates 41 is on the surface of the conveyor 11. Under the action of each set of guide plates 41, the angle steel conveyed by the conveyor 11 can be guided so that the end to be cut can remain parallel, reducing the error generated during the cutting process; A mounting frame is fixed on the operating table 10. A fourth electro-hydraulic rod 42 is mounted on the mounting frame. A horizontal plate is installed at one end of the fourth electro-hydraulic rod 42, and three positioning posts 43 corresponding to the three sets of guide plates 41 are fixed at the bottom of the horizontal plate. Specifically, when the angle steel is horizontally guided to the surface of the operating table 10 by the guide plate 41, and the corner cutting position is in the cutting position, the fourth electric hydraulic rod 42 is activated to drive the horizontal plate to move the positioning column 43 downward, so that the positioning column 43 abuts against the angle steel, fixing the angle steel to the surface of the operating table 10, ensuring that it will not move during the corner cutting process. After the cutting is completed, the positioning column 43 is reset upward, and the angle steel with the corner cut can be taken out.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an angle adjustment unit 20 is installed on the operating table 10 via a bracket 12. It should be noted that the bracket 12 is fixed on the operating table 10. The angle adjustment unit 20 includes a support frame 21 that is slidably mounted on the bracket 12. An inner frame 23 is mounted inside the support frame 21. Specifically, the inner frame 23 is rotatably connected inside the support frame 21. A sectional adjustment component 25 is mounted inside the inner frame 23. The sectional adjustment component 25 is connected to the cutting component 30 via the base 254. The support frame 21, together with the cutting component 30, is moved downward via the first electro-hydraulic rod 22 mounted on the top of the bracket 12. One end of the first electro-hydraulic rod 22 is fixed to the top of the support frame 21. Specifically, when the first electro-hydraulic rod 22 is used to drive the cutting component 30 downward to cut the angle steel, it is necessary to ensure that the cutting component 30 remains in its initial state and has not been adjusted in angle. In this state, the angle steel can be cut vertically. The inner frame 23 is rotated by the first motor 24 installed on the outer wall of the support frame 21 to control the cutting angle of the cutting assembly 30. The output end of the first motor 24 is connected to one end of the inner frame 23. Specifically, when the cutting angle of a batch of angle steels moved to the bottom of the cutting assembly 30 is 45° or other angles (this angle is a vertically varying angle), the first motor 24 is started to drive the inner frame 23 together with the cutting assembly 30 inside it to rotate to the required angle. In this state, due to the change in the cutting angle, the cutting assembly 30 cannot be controlled to move down to complete the cutting operation by the first electric hydraulic rod 22. The cutting assembly 30 includes a mounting base 31 rotatably connected to the base 254, a mounting shaft rotatably connected to the mounting base 31, and a cutting blade 32 mounted on one end of the mounting shaft. Preferably, the cutting blade 32 is a carbide circular saw blade or an abrasive wheel cutting blade. A fourth motor 33 with its output end connected to the mounting shaft is mounted on one end of the mounting base 31.

[0019] like Figure 2 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the sectional adjustment assembly 25 includes multiple positioning seats 251 fixed on the inner frame 23. A shaft 252 is rotatably connected to the positioning seat 251 through a through hole. It should be noted that a damping pad is provided on the inner wall of the through hole, so that a damping force is generated between the through hole and the shaft 252. This damping force can fix the shaft 252 in the rotated position after driving the structure mounted on it to rotate, and it will not rotate on its own due to its own weight. A second motor 256 with an output end connected to one of the shafts 252 is assembled on the outer wall of the inner frame 23. Multiple positioning slots are provided at one end of two shafts 252 and at both ends of the other shaft 252. The four positioning slots are distributed in pairs, and each pair contains a plug rod 257. In particular, the positioning slots and plug rods 257 have polygonal cross sections. Preferably, the polygon is a 24-sided polygon, that is, it has 24 lateral faces. It should be noted that the rotation angle of each shaft 252 must be 15° or a multiple of 15°. The outer surface of the plug rod 257 is fitted with a bearing seat 258. Push plates are fixed on both bearing seats 258. On both sides of the positioning seat 251 in the middle, a third electro-hydraulic rod 259 connected to the push plate is mounted through an extension plate. In particular, the installation positions of the two push plates and the two third electro-hydraulic rods 259 are staggered vertically, so that the two third electro-hydraulic rods 259 are staggered after being connected to the push plates, which will not affect their respective movements. Specifically, by setting up two insert rods 257, the three shafts 252 can be connected together, thereby enabling the three shafts 252 to rotate together; Meanwhile, when the three angle steels conveyed to the cutting assembly 30 have different cutting angles, for example, if the side closer to the second motor 256 is set as left, when the angles of the three angle steels cut from left to right are 15°, 30° and 45° respectively, firstly, the second motor 256 controls the three shafts 252 to rotate together, so that the three cutting assemblies 30 rotate to the corresponding 45° angle. Then, by activating the third electric hydraulic rod 259 located on the left, the bearing seat 258 on the right and the insertion rod 257 on the right are pulled to the left, so that one end of it is moved out from the shaft 252 on the right. At this time, the right shaft 252 and the cutting assembly 30 on it will be kept at 45°. In this state, starting the second motor 256 can only control the left shaft 252 and the middle shaft 252 to rotate together. At this time, the second motor 256 controls the left shaft 252 and the middle shaft 252 to drive the cutting component 30 connected to them to rotate to the corresponding 30° angle. Then, by starting the third electric hydraulic rod 259 located on the right, the bearing seat 258 on the left and the insertion rod 257 on the left are pulled to the right, so that one end of them moves out of the left shaft 252. At this time, the middle shaft 252 and the cutting component 30 on it will be kept at 30°. When the second motor 256 is started, it will drive the left shaft 252 to rotate independently. In this state, the left shaft 252 and the cutting component 30 on it will be driven to rotate to the corresponding 15° position. At this time, the angles of the three cutting components 30 are adjusted from left to right to 15°, 30° and 45° respectively. After adjustment, the two insert rods 257 are reset so that they are re-inserted into the shafts 252 on the left and right sides, so that the three shafts 252 are connected together. It should be noted that since the insert rod 257 and the slot have 24 faces, and each face corresponds to an angle of 15°, the insert rod 257 can always be reinserted into the slot when the shaft 252 rotates by an angle of 15° and multiples of 15°. A retainer 253 is fixed on the shaft 252, and a base 254 is inserted into the retainer 253. Preferably, springs are installed at both ends of the base 254 inserted into the retainer 253, and the top of the springs is connected to the top wall of the retainer 253. A third motor 2510 with its output end connected to the top of the mounting base 31 is installed in the middle of the base 254. Specifically, when the lateral angle of the cutting assembly 30 needs to be adjusted, the third motor 2510 is started, which drives the mounting base 31 to rotate laterally, thereby causing the mounting base 31 and the cutting blade 32 to rotate to the required angle. Combined with the vertical angle adjustment, the cutting assembly 30 can be adapted to various angle cutting requirements without the need for manual adjustment of the angle steel position.

[0020] like Figure 2 , Figure 3 and Figure 5 As shown, a second electro-hydraulic rod 255 is fixed on the outer wall of the retainer 253. One end of the second electro-hydraulic rod 255 is fixed to the base 254. Specifically, after the angle of the cutting component 30 is adjusted, the first electro-hydraulic rod 22 controls the support frame 21 and the cutting component 30 inside it to move downwards until the bottom of the cutting blade 32 contacts the surface of the angle steel. After contact, the movement stops. At this time, the second electro-hydraulic rod 255 is started to push the cutting component 30, which is tilted after the base 254 is tilted, to move tilted. During the process, the fourth motor 33 controls the rotation of the cutting blade 32 to complete the corner cutting operation.

[0021] like Figure 1 and Figure 8 As shown, the bottom of the operating table 10 is provided with a waste collection assembly 50. The waste collection assembly 50 includes a guide frame 51 installed on the lower surface of the operating table 10. The surface of the operating table 10 is provided with a discharge groove 52 corresponding to the inlet end of the guide frame 51. A receiving box 53 corresponding to the outlet of the guide frame 51 is provided on one side of the operating table 10. Specifically, after the angle steel is cut, the first motor 24 is started to drive the inner frame 23 and the cutting component 30 inside it to rotate inward. During the process, the cutting blade 32 gradually pushes the cut waste material to the feeding trough 52, and gradually falls onto the surface of the guide frame 51. The waste material is then guided by the guide frame 51 to the receiving box 53 for centralized collection. There is no need for manual collection of waste material and no need to set up an additional cleaning mechanism.

[0022] Specifically, the multi-angle cutting device for this power tower operates as follows: 1. Equipment debugging and parameter setting: According to the specifications of the angle steel to be processed, adjust the installation position of the guide plate 41 by bolts so that the width of the exit end enclosed by each group of guide plates 41 matches the width of the angle steel; according to the cutting requirements, determine the vertical and horizontal cutting angles of each angle steel, and preset the operating parameters of the first motor 24, the second motor 256, and the third motor 2510. 2. Angle steel conveying and positioning: Place the angle steel to be processed on the roller conveyor 11, start the conveyor 11, and under the guidance of the guide plate 41 and the limiting column, the angle steel is conveyed parallel to the surface of the operating table 10 until the position to be cut is moved below the cutting component 30; start the fourth electric hydraulic rod 42, drive the horizontal plate to move the positioning column 43 downward, and the positioning column 43 abuts against the upper surface of the angle steel, and firmly fixes the angle steel on the operating table 10; 3. Adjusting the chamfer angle: If multiple angle steels have the same cutting angle, the first motor 24 drives the inner frame 23 to rotate to the preset vertical angle, and the third motor 2510 starts to drive the mounting base 31 to drive the cutting blade 32 to rotate to the preset horizontal angle, thus completing the composite angle adjustment. If multiple angle steels have different cutting angles (e.g., three angle steels require vertical angles of 15°, 30°, and 45° respectively), first, control the three shafts 252 to rotate in linkage to the maximum angle (e.g., 45°) via the second motor 256. Then, activate the third electric hydraulic rod 259 on the left to pull the right insert rod 257 away from the right shaft 252. Next, control the left and middle shafts 252 to rotate in linkage to the middle angle (e.g., 30°). Then, activate the third electric hydraulic rod 259 on the right to pull the left insert rod 257 away from the left shaft 252. Finally, drive the left shaft 252 to rotate to the minimum angle (e.g., 15°) separately. After adjustment, reset the insert rod 257 to lock the shaft 252. Then, adjust the lateral angle of each cutting blade 32 separately via the third motor 2510. 4. Corner cutting: Start the first electric hydraulic rod 22 to drive the support frame 21 and the cutting assembly 30 to move downwards until the bottom of the cutting blade 32 contacts the surface of the angle steel and then stops; start the fourth motor 33 to drive the cutting blade 32 to rotate at high speed, and at the same time start the second electric hydraulic rod 255 to push the base 254, so that the tilted cutting assembly 30 moves along the corner cutting direction to complete the corner cutting operation. 5. Waste collection and workpiece removal: After the corner cutting is completed, turn off the fourth motor 33, and the second electric hydraulic rod 255 and the first electric hydraulic rod 22 reset in sequence; start the first motor 24 to drive the inner frame 23 to rotate inward, and the cutting blade 32 pushes the waste into the feeding trough 52, which is then guided by the guide frame 51 to the receiving box 53 for centralized collection; start the fourth electric hydraulic rod 42 to reset the positioning column 43, and then remove the processed angle steel to complete a single processing flow. The above steps can be repeated for batch processing.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
