Description

Technical Field

[0001] This utility model belongs to the technical field of gantry shearing machines, specifically relating to an induction anti-pinch protective door for gantry shearing machines. Background Technology

[0002] Gantry shears are a type of mechanical equipment widely used in metal processing, waste recycling and other fields. They are mainly used for shearing materials such as metal sheets and bars. Due to their large shearing force and fast operating speed, improper operation or insufficient protection can easily cause serious injury to the operator's hands or other body parts.

[0003] Common protective measures for gantry shears mainly include mechanical protective barriers and photoelectric sensor detection. Although mechanical barriers have a simple structure, they can affect the material in and out and make operation inconvenient. Real-time monitoring of the shearing area by camera may have blind spots due to the fixed angle of the camera, which cannot fully cover the dynamic working environment and thus limits its practical application. To address this, we have designed an induction anti-pinch protective door for gantry shears to provide an alternative technical solution to the above-mentioned technical problems.

[0024] 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.

[0025] Reference Figure 1-7 A sensor-operated anti-pinch protective door for a gantry shear machine includes a vertical gantry shear machine 1. Both ends of one side of the vertical gantry shear machine 1 are fixed with L-shaped fixing blocks 2. An infrared sensor 3 is slidably connected inside the L-shaped fixing block 2. A limiting mechanism for limiting the infrared sensor 3 is provided inside the L-shaped fixing block 2.

[0026] The top of the vertical gantry shear machine 1 is provided with a horizontal rotating rod 6, an industrial camera 5 is sleeved on the outside of the horizontal rotating rod 6, and a rotating mechanism for rotating the horizontal rotating rod 6 is provided on the outside of the vertical gantry shear machine 1.

[0027] One end of the infrared sensor 3 is fixed with a vertical dovetail slider. The L-shaped fixing block 2 has a vertical dovetail groove inside. The infrared sensor 3 and the L-shaped fixing block 2 are slidably connected by the vertical dovetail slider and the vertical dovetail groove. The vertical dovetail slider and the vertical dovetail groove allow the infrared sensor 3 to slide vertically inside the L-shaped fixing block 2, allowing the infrared sensor 3 to move out of the L-shaped fixing block 2.

[0028] The limiting mechanism includes an infrared sensor 3, a rectangular sliding column 8 fixed on one side of the infrared sensor 3, a rectangular pull plate 4 provided at one end of the L-shaped fixing block 2, and longitudinal limiting rods 10 fixed at the top and bottom of the rectangular pull plate 4 near the end of the L-shaped fixing block 2. The longitudinal limiting rods 10 pass through the interior of the L-shaped fixing block 2 and are slidably connected to the L-shaped fixing block 2. A longitudinal rigid spring 11 is provided between the L-shaped fixing block 2 and the rectangular pull plate 4 and on the outside of the longitudinal limiting rods 10. A circular limiting hole adapted to the rectangular sliding column 8 is opened inside the rectangular sliding column 8.

[0029] The L-shaped fixing block 2 has a vertical sliding groove inside. The rectangular sliding column 8 is located inside the vertical sliding groove and is slidably connected to the L-shaped fixing block 2 through the vertical sliding groove. The vertical sliding groove allows the rectangular sliding column 8 to slide vertically inside the L-shaped fixing block 2. When the longitudinal limiting rod 10 enters the interior of the rectangular sliding column 8, it can restrict the movement of the infrared sensor 3 inside the L-shaped fixing block 2. When the longitudinal limiting rod 10 moves out of the interior of the rectangular sliding column 8, the infrared sensor 3 can be disassembled.

[0030] Here, by setting the vertical dovetail slider and the vertical dovetail groove, the infrared sensor 3 can slide vertically inside the L-shaped fixed block 2, allowing the infrared sensor 3 to move out of the L-shaped fixed block 2. When the infrared sensor 3 needs to be disassembled, the rectangular pull plate 4 is pulled. The pulling of the rectangular pull plate 4 allows the longitudinal limiting rod 10 to move inside the L-shaped fixed block 2. The movement of the rectangular pull plate 4 causes the longitudinal rigid spring 11 to deform under force. When the longitudinal limiting rod 10 enters the rectangular sliding column 8, it can restrict the movement of the infrared sensor 3 inside the L-shaped fixed block 2. When the longitudinal limiting rod 10 moves out of the rectangular sliding column 8, the infrared sensor 3 can be disassembled.

[0031] The rotating mechanism includes an L-shaped fixed plate 7, which is fixedly connected to the outside of the vertical gantry shear machine 1. A longitudinal hydraulic cylinder 12 is fixed to the outside of the L-shaped fixed plate 7. The output end of the longitudinal hydraulic cylinder 12 is rotatably connected to a transverse rotating column 13 through a bearing. An oblique transmission column 15 is rotatably connected to the outside of the transverse rotating column 13 through a bearing. A rectangular rotating block 9 is rotatably connected to one end of the oblique transmission column 15 through a pin. The rectangular rotating block 9 is sleeved on the outside of the transverse rotating rod 6 and is fixedly connected to the transverse rotating rod 6.

[0032] The horizontal rotating rod 6 passes through the interior of the L-shaped fixed plate 7 and is rotatably connected to the L-shaped fixed plate 7 through a bearing. The bearing allows the horizontal rotating rod 6 to rotate inside the L-shaped fixed plate 7, so that the industrial camera 5 can rotate with the horizontal rotating rod 6, thereby adjusting the shooting angle of the industrial camera 5.

[0033] A longitudinal rectangular slider 14 is fixed on one side of the transverse rotating column 13. A longitudinal groove is provided inside the L-shaped fixing plate 7. The longitudinal rectangular slider 14 is located inside the longitudinal groove and is slidably connected to the L-shaped fixing plate 7 through the longitudinal groove. The slidable connection through the longitudinal groove allows the transverse rotating column 13 to move outside the L-shaped fixing plate 7. The movement of the transverse rotating column 13 causes the rectangular rotating block 9 to rotate through the oblique transmission column 15.

[0034] An arc-shaped fixing block is fixed to the outside of the longitudinal hydraulic cylinder 12. The arc-shaped fixing block is close to the side of the L-shaped fixing plate 7 and is fixedly connected to the L-shaped fixing plate 7, so that the longitudinal hydraulic cylinder 12 can be fixed to the outside of the L-shaped fixing plate 7. Through the operation of the longitudinal hydraulic cylinder 12, the transverse rotating column 13 can move.

[0035] When it is necessary to adjust the shooting angle of the industrial camera 5, the operation of the longitudinal hydraulic cylinder 12 causes the transverse rotating column 13 to move. The movement of the transverse rotating column 13 causes the longitudinal rectangular slider 14 to move inside the L-shaped fixed plate 7. The movement of the transverse rotating column 13 causes the rectangular rotating block 9 to drive the transverse rotating rod 6 to rotate through the oblique transmission column 15. This allows the transverse rotating rod 6 to rotate inside the L-shaped fixed plate 7, thereby enabling the industrial camera 5 to rotate with the transverse rotating rod 6, thus allowing the shooting angle of the industrial camera 5 to be adjusted.

[0036] The dual detection mechanism of detachable infrared sensor 3 and adjustable angle industrial camera 5 significantly improves protection reliability and avoids the risk of misjudgment from a single detection method. The infrared sensor 3 can be disassembled inside the L-shaped fixing block 2 to facilitate the maintenance and replacement of the infrared sensor 3. The rotatable industrial camera 5 can adjust the shooting angle according to the usage requirements, effectively eliminating the visual blind spots of traditional fixed monitoring.

[0037] Working principle: The vertical dovetail slider and vertical dovetail groove enable the infrared sensor 3 to slide vertically inside the L-shaped fixed block 2, allowing the infrared sensor 3 to move out of the L-shaped fixed block 2. When the infrared sensor 3 needs to be disassembled, the rectangular pull plate 4 is pulled. The pulling of the rectangular pull plate 4 causes the longitudinal limiting rod 10 to move inside the L-shaped fixed block 2. The movement of the rectangular pull plate 4 causes the longitudinal rigid spring 11 to deform under force. When the longitudinal limiting rod 10 enters the rectangular sliding column 8, it can restrict the movement of the infrared sensor 3 inside the L-shaped fixed block 2. When the longitudinal limiting rod 10 moves out of the rectangular sliding column 8, the infrared sensor 3 can be disassembled.

[0038] When the shooting angle of the industrial camera 5 needs to be adjusted, the operation of the longitudinal hydraulic cylinder 12 causes the transverse rotating column 13 to move. The movement of the transverse rotating column 13 causes the longitudinal rectangular slider 14 to move inside the L-shaped fixed plate 7. The movement of the transverse rotating column 13 causes the rectangular rotating block 9 to drive the transverse rotating rod 6 to rotate through the oblique transmission column 15. This allows the transverse rotating rod 6 to rotate inside the L-shaped fixed plate 7, thereby enabling the industrial camera 5 to rotate with the transverse rotating rod 6, thus allowing the shooting angle of the industrial camera 5 to be adjusted.
