Abstract
Description
Technical Field
[0001] This invention relates to the field of conveying technology, specifically to an automatic conveying device for flame cutting of elevator counterweights based on vision detection. Background Technology
[0002] During elevator operation, the counterweight plays a crucial role in balancing the weight of the car, thereby improving the elevator's operating efficiency and safety. The precise manufacturing of the counterweight is critical to the overall elevator performance, especially in the flame-cutting process, where accurate control of its size and shape can effectively prevent problems during subsequent installation and use. Therefore, using automated equipment for processing and conveying the counterweight not only improves production efficiency but also ensures consistent product quality.
[0003] When flame-cutting elevator counterweights, since the counterweight thickness is greater than 80mm, a two-stage cutting method is usually used. This is because a single cut through the thick plate causes heat to accumulate dramatically in the thickness direction, forming a hardening and embrittlement zone. Furthermore, during cutting, the oxygen jet has difficulty penetrating the bottom, easily leading to slag accumulation at the lower edge and a cut that is wider at the top and narrower at the bottom. However, with a two-stage cutting method, the limited kerf width of the counterweight means that the second cut is blocked by the cut surface from the first cut. This also causes heat to accumulate in the thickness direction, and the oxygen flow is poor, thus reducing the cutting efficiency. Summary of the Invention

[0015] The present invention has the following beneficial effects:
[0016] 1. This automatic conveying equipment for flame cutting of elevator counterweights based on vision detection adopts a step-by-step cutting method, dividing the heat input into two stages. Each stage only acts on half-thickness areas of the counterweight, allowing the material time to dissipate heat between the two cuts. This effectively suppresses thermal stress concentration and reduces overall warping and twisting. The first half-thickness cut forms a stable cutting channel, making it easier for oxygen to reach the bottom during the second cut, achieving uniform combustion and obtaining a flat, slag-free cut surface, reducing subsequent grinding time. After the first cut and before the second cut, the base plate drives the longitudinal plate and the clamping plate to move, so that the clamping plate presses down on both sides of the counterweight, causing the counterweight to bend to a certain extent, exposing the cutting surface, facilitating the second cut, increasing oxygen flow, and further improving the cutting effect.
[0017] 2. This automatic conveying equipment for flame cutting of elevator counterweights based on vision detection can drive the connecting plate to slide along the moving groove when the clamping plate presses down on both ends of the counterweight. At the same time, the clamping plate can adjust its angle, so that the clamping plate can accurately adapt to the dynamic position changes of the counterweight during the pressing process. This effectively avoids clamping instability or cutting interference caused by position deviation, and significantly improves the accuracy and effect of subsequent cutting operations.
[0018] 3. This automatic conveying equipment for flame cutting of elevator counterweights based on vision detection, through the movement of the base plate along the conveyor line, drives the third limit ball to slide along the third track groove. After the clamping plate presses down on both ends of the counterweight, the side plate can move upward. The upward movement of the side plate drives the longitudinal plate and the clamping plate to move upward synchronously, thereby lifting the counterweight a certain distance. This allows the position of the counterweight that needs to be cut a second time to move towards the nozzle of the flame cutting gun, shortening the distance between the cutting position and the nozzle. This facilitates the precise adjustment of the counterweight to the optimal cutting position, effectively improving the cutting effect. Attached Figure Description

A first horizontal plate 16 is slidably disposed on the top of the vertical plate 10, and a second horizontal plate 17 is fixed on the bottom of the vertical plate 10. A clamping plate 11 is disposed on the surface of the first horizontal plate 16 and the second horizontal plate 17. A second sliding rod 18 is fixed on the lower surface of the first horizontal plate 16. A second sliding groove 19 is opened on the fixed base 1 for sliding with the second sliding rod 18. The bottom end of the second slide bar 18 is fixed with a second limiting ball 20, and the bottom of the second slide groove 19 is provided with a second track groove 21 for the second limiting ball 20 to slide. A straight rod 36 is fixed on one side of the fixed base 1. A fixed frame 37 is elastically provided on the straight rod 36. A positioning frame 38 is fixed at the top of the fixed frame 37. A reciprocating screw 39 is rotatably provided on the inner side of the positioning frame 38. A servo motor 40 connected to the reciprocating screw 39 is fixed on the outer surface of the positioning frame 38. A transmission seat 41 is threadedly connected to the reciprocating screw 39. The flame cutting gun 4 is fixed to the transmission seat 41. A positioning rod 42 is fixed to the surface of the fixing frame 37, an electric push rod 43 is fixed to the surface of the positioning rod 42, and a stop bar 44 for contacting the base plate 6 is fixed to the output end of the electric push rod 43.
[0035] In this technical solution, the counterweight 3 is first placed on the placement platform 7, and the counterweight 3 is automatically conveyed by the conveyor line 2. During the conveying process, the base plate 6 drives the second slide rod 18 to slide along the second slide groove 19, and the second slide rod 18 drives the second limit ball 20 to slide along the second track groove 21. The second track groove 21 includes a third horizontal part 211, a third descending part 212, a fourth horizontal part 213, and a third ascending part 214 that are connected together. Figure 1 and Figure 12 As shown, before the second limiting ball 20 slides to point a on the right, the second limiting ball 20 slides from the third horizontal part 211 to the third descending part 212 and slides along the third descending part 212, causing the second limiting ball 20 to drive the second sliding rod 18 to move downwards, as shown. Figure 9 As shown, when the second slide bar 18 moves downward, it pulls the first horizontal plate 16 downward, and the first horizontal plate 16 drives the clamping plate 11 to move downward, so that the clamping plate 11 clamps and fixes the two sides of the counterweight 3. For counterweight 3 with a thickness greater than 80mm, if a single cut through the thick plate is used, heat will accumulate violently in the thickness direction, forming a hardening and embrittlement zone. Furthermore, during cutting, the oxygen jet has difficulty penetrating the bottom, easily leading to slag accumulation at the lower edge and a cut that is wider at the top and narrower at the bottom. Therefore, when the base plate 6 moves the fixed counterweight 3 to point b, the base plate 6 abuts against the stop bar 44. A slide rail 45 is provided on the straight rod 36 for the fixed frame 37 to slide. A spring is fixed between the inner wall of the slide rail 45 and the bottom end of the fixed frame 37, causing the fixed frame 37 to move synchronously with the base plate 6. When the fixed frame 37 moves synchronously with the base plate 6, the spring is stretched and stores force, allowing the flame cutting gun 4 to flame-cut the counterweight 3. Simultaneously, the servo motor 40 drives the reciprocating screw 39 to rotate, and the reciprocating screw 39 drives the transmission seat 41 to move. The moving seat 41 drives the flame cutting gun 4 to move, so that the flame cutting gun 4 can make a transverse cut on the counterweight 3. When the flame cutting gun 4 moves from one end of the counterweight 3 to the other end, it completes the cutting of half the thickness of the counterweight 3. Then the transmission seat 41 moves in the opposite direction along the reciprocating screw 39 and resets, driving the flame cutting gun 4 to move in the opposite direction, thereby completing the cutting of the other half thickness of the counterweight 3. Through the above process, the step-by-step cutting can divide the heat input into two parts, each time acting only on the half-thick area of the counterweight 3, allowing the material time to dissipate heat between the two cuts, effectively suppressing the concentration of thermal stress, reducing overall warping and twisting. Moreover, cutting half the thickness first can form a stable cutting channel, and the oxygen flow can more easily reach the bottom during the second cut, achieving uniform combustion, obtaining a flat, slag-free cut surface, and reducing subsequent grinding time. After the counterweight 3 is cut, the electric push rod 43 retracts, driving the stop bar 44 to move, causing the stop bar 44 to separate from the base plate 6. The spring releases the force, causing the fixing frame 37 to reset. Then, the counterweight 3 after cutting continues to be transported to the viewing angle detection station 5 along the conveyor line 2. The viewing angle detection station 5 collects images of the surface of the counterweight 3, and uses algorithms to identify its contour, size, position and surface defects, and detects whether the counterweight 3 after cutting is qualified. During the second cut, the limited slit width of the counterweight 3 causes the second cut to be obstructed by the cut surface from the first cut, resulting in poor oxygen flow. Therefore, after the first cut and before the second cut, i.e., when the base plate 6 moves to point c, the base plate 6 drives the first sliding rod 12 to slide along the first sliding groove 13. The first sliding rod 12 drives the first limiting ball 14 to slide along the first track groove 15. The first track groove 15 includes a first horizontal part 151, a first descending part 152, a first rising part 153, a second horizontal part 154, a second descending part 155, and a second rising part 156 connected together. Then, the base plate 6 continues to move forward. At this time, the first limiting ball 14 slides from the first horizontal part 151 to the first descending part 152 and slides along the first descending part 152, so that the first limiting ball... Ball 14 drives the first sliding rod 12 to move downward, the first sliding rod 12 pulls the support rod 9 to move downward, the support rod 9 drives the longitudinal plate 10 to move downward, the longitudinal plate 10 drives the clamping plate 11 to move downward as a whole. Due to the resistance of the placement platform 7 to the middle position of the counterweight 3, the clamping plate 11 presses down on both sides of the counterweight 3, causing the counterweight 3 to bend to a certain extent, exposing the cutting surface, thus facilitating secondary cutting, increasing oxygen flow, and further improving the cutting effect. After the counterweight 3 is pressed down at both ends, the first limiting ball 14 slides along the second horizontal part 154 to perform the second cutting operation. Then, when the first limiting ball 14 slides along the second rising part 156, the longitudinal plate 10 drives the clamping plate 11 to reset. At this time, the bottom plate 6 moves to position d, and then the viewing angle is detected. In order to enable the vertical plate 10 to drive the clamping plate 11 to move downward synchronously, and enable the clamping plate 11 to press down on both ends of the counterweight 3, the fourth horizontal part 213 is provided with a fifth descending part 215 and a fifth rising part 216. When the first limiting ball 14 slides along the first descending part 152, the second limiting ball 20 slides along the fifth descending part 215, so that the first sliding rod 12 and the second sliding rod 18 move downward synchronously without relative displacement. Thus, under the premise that the clamping plate 11 clamps and fixes the counterweight 3, the counterweight 3 is pressed down. Then, when the first limiting ball 14 slides along the first rising part 153, the second limiting ball 20 slides along the fifth rising part 216, so that the first sliding rod 12 and the second sliding rod 18 move upward synchronously and reset. In this technical solution, the counterweight 3 is made of low-carbon steel (such as Q235B), which has strong plastic deformation ability at the cut edge after cutting, and can be bent to a certain extent. It is not easy to crack when bent, making it suitable for elevator counterweight 3. The flame cutting gun 4 can complete the flame cutting of the counterweight 3. The viewing angle detection station 5 uses a high-resolution industrial camera to collect images of the surface of the counterweight 3. Both the flame cutting gun 4 and the viewing angle detection station 5 are existing technologies and are not the innovations of this application, so they will not be described in detail.
[0036] In Example 2, during the downward pressing of the clamping plate 11 against the two ends of the counterweight 3, the two ends of the counterweight 3 do not move in a straight line, but rather in an arc. If the clamping plate 11 only moves downward, it will rub against the surface of the counterweight 3. Since the clamping plate 11 is in a clamping state against the counterweight 3, jamming may occur, causing structural damage and affecting the cutting effect. To address this problem, this example is an improvement based on Example 1. For details, please refer to... Figures 1-13 A connecting plate 22 is fixed on the surface of the clamping plate 11. The first horizontal plate 16 and the second horizontal plate 17 are both provided with a moving groove 23 for the connecting plate 22 to move. A rotating shaft 24 is rotatably provided at the end of the connecting plate 22. A gear 25 is fixed at the end of the rotating shaft 24. A toothed plate 26 that meshes with the gear 25 is fixed inside the moving groove 23. A movable block 27 is fixed to the end of the rotating shaft 24. The movable block 27 is slidably disposed in the movable groove 23. A transmission rod 28 is fixed to the surface of the movable block 27. A vertical groove 29 for the transmission rod 28 to slide is opened on the surface of the side plate 8. The end of the transmission rod 28 is fixed with a fourth limiting ball 30, and the interior of the vertical groove 29 is provided with a fourth track groove 31 for the fourth limiting ball 30 to slide.
[0037] In this technical solution, when the longitudinal plate 10 drives the first transverse plate 16 and the second transverse plate 17 to move downwards synchronously, the moving groove 23, after the clamping plate 11 is clamped to the surface of the counterweight 3, and when the end of the counterweight 3 presses down along the arc-shaped trajectory, as shown... Figure 9 As shown, at this time, the clamping plate 11 can drive the connecting plate 22 to move to the right along the moving groove 23. At the same time, when the connecting plate 22 moves to the right, it drives the rotating shaft 24 to move to the right. The rotating shaft 24 drives the gear 25 to move to the right. Due to the meshing of the gear 25 and the toothed plate 26, when the gear 25 moves to the right, it can drive the rotating shaft 24 to rotate. The rotation of the rotating shaft 24 drives the connecting plate 22 to rotate. The rotation of the connecting plate 22 drives the clamping plate 11 to rotate. Thus, while the clamping plate 11 moves to the right, the angle of the clamping plate 11 is adjusted, so that the clamping plate 11 can adapt to the position change during the pressing process of the counterweight 3, thereby further improving the subsequent cutting effect. When the clamping plate 11 moves to the right, it is driven only by the friction between the clamping plate 11 and the surface of the counterweight 3. If there is a relative displacement between the clamping plate 11 and the counterweight 3, the clamping plate 11 will not be able to adapt to the curvature change at the end of the counterweight 3. Therefore, when the clamping plate 11 clamps and fixes the counterweight 3 downward, it drives the transmission rod 28 to slide downward along the vertical groove 29. The transmission rod 28 drives the fourth limiting ball 30 to slide along the fourth track groove 31. The fourth limiting ball 30 slides along the vertical part 311. Slide and slide to the bottom of the vertical part 311. Then, when the vertical plate 10 drives the first horizontal plate 16 and the second horizontal plate 17 to move downwards synchronously, the fourth limiting ball 30 slides downwards along the inclined part 312, so that the fourth limiting ball 30 drives the transmission rod 28 to move to the right. The transmission rod 28 drives the moving block 27 to move to the right in the moving groove 23. The moving block 27 drives the clamping plate 11 to move to the right, so that the clamping plate 11 can be adjusted in time to adapt to the curvature change of the end of the counterweight 3.
[0038] In Example 3, since the cut already has depth after the first cut, the flame cutting gun 4 will be farther away from the second cutting position when the counterweight 3 is cut a second time. This prevents the flame cutting gun 4 from continuing to cut the counterweight 3 from the optimal position, thus reducing the cutting effect. To address this problem, this example is an improvement on Example 2. For details, please refer to... Figures 1-13 The bottom of the side plate 8 is fixed with a third slide rod 32. The interior of the fixed base 1 is provided with a third slide groove 33 for the third slide rod 32 to slide. The bottom end of the third slide rod 32 is fixed with a third limiting ball 34. The bottom of the third slide groove 33 is provided with a third track groove 35 for the third limiting ball 34 to slide.
[0039] In this technical solution, when the base plate 6 moves with the conveyor line 2, it drives the third slide rod 32 to slide along the third slide groove 33, and the third slide rod 32 drives the third limiting ball 34 to slide along the third track groove 35. Figure 12 and Figure 13As shown, the third track groove 35 includes a fifth horizontal section 351, a fourth rising section 352, a sixth horizontal section 353, and a fourth descending section 354 connected in series. The fourth horizontal section 213 is provided with a sixth rising section 217 connected to the fifth descending section 215 and a sixth descending section 218 connected to the fifth rising section 216. After the clamping plate 11 presses down on both ends of the counterweight block 3, the third limiting ball 34 slides from the fifth horizontal section 351 to the fourth rising section 352 and slides along the fourth rising section 352, causing the third limiting ball 34 to drive the third sliding rod 32 to move upward. The upward movement of the third sliding rod 32 drives the side plate 8 to move upward. At this time, the first track groove 15... The first rising part 153 and the sixth rising part 217 of the second track groove are provided. When the third limiting ball 34 slides along the fourth rising part 352, the first limiting ball 14 slides along the first rising part 153 and the second limiting ball 20 slides along the sixth rising part 217. This allows the side plate 8, the longitudinal plate 10 and the clamping plate 11 to move upward synchronously. This allows the clamping plate 11 to lift the counterweight 3 upward a certain distance, so that the position where the counterweight 3 needs to be cut for the second time can move towards the nozzle of the flame cutting gun 4. This makes the cutting position closer to the nozzle of the flame cutting gun 4, which makes it easier to adjust the counterweight 3 to the optimal cutting position and further improves the cutting effect. During cutting, the third limiting ball 34 slides along the sixth horizontal part 353. After cutting, the third limiting ball 34 slides along the fourth descending part 354, the first limiting ball 14 slides along the second descending part 155, and the second limiting ball 20 slides along the sixth descending part 218.
