DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the application.

[0019] Referring to Figures 1-9 The present application provides a technical solution: In the device, the support 1 is the basic support component of the entire device, which provides a mounting platform for all components such as the conveying assembly 2, the turnover assembly 4, the grabbing assembly 3, etc. through its stable structure, to ensure that the relative stable positional relationship of each component is maintained during the working process.

[0020] The conveying assembly 2 adopts a roller conveyor, which is stably mounted on the support 1. The roller conveyor is composed of a series of rollers, which are arranged in parallel and equidistant to each other. When it is necessary to convey the metal block, the operator places the metal block on the rollers, and drives the rollers to rotate through a driving device (such as a motor, a chain, not shown in the figure, which is a mature existing technology in the technical field, and will not be described here, and the designer can select a suitable driving device and roller conveyor according to the actual situation), thereby realizing the continuous movement of the metal block on the roller conveyor and conveying the metal block to the designated position.

[0021] The turnover assembly 4 is also mounted on the support 1, and its core component is the rotating shaft 41 and the turnover plate 42. The rotating shaft 41 is rotatably arranged on the support 1 through a bearing (not shown in the figure), and the turnover plate 42 is fixedly arranged on the rotating shaft 41. The turnover plate 42 is also connected with the turnover telescopic cylinder 43 between the support 1, one end of the turnover telescopic cylinder 43 is rotatably connected with the support 1, and the other end is rotatably connected with the turnover plate 42. When the turnover telescopic cylinder 43 is extended or retracted, it drives the turnover plate 42 to rotate around the rotating shaft 41, thereby realizing the angle adjustment of the turnover plate 42.

[0022] On the turnover plate 42, a limiting frame 44 and a anti-falling assembly 45 are fixedly installed. The shape and size of the limiting frame 44 are adapted to the metal block to be conveyed, and when the metal block is conveyed onto the turnover plate 42, the limiting frame 44 will preliminarily limit the metal block to prevent it from sliding randomly on the turnover plate 42, and ensure that the metal block maintains a relatively stable position during the subsequent turnover process.

[0023] On the turnover plate 42, a plurality of eye wheels 46 are fixedly arranged. These eye wheels 46 are uniformly distributed on the surface of the turnover plate 42, and their installation height is consistent with the height of the conveying assembly 2. When the metal block is conveyed from the conveying assembly 2 to the turnover plate 42, since the height of the eye wheels 46 is the same as that of the conveying assembly 2, the metal block can smoothly transition from the conveying assembly 2 to the turnover plate 42 without jamming or collision due to the height difference. The eye wheels 46 can rotate flexibly, and when the metal block moves on the turnover plate 42, the eye wheels 46 can reduce the friction between the metal block and the turnover plate 42 by rotating, so that the metal block can more smoothly enter the designated position of the limiting frame 44.

[0024] Meanwhile, the turnover plate 42 is provided with a position giving slot 47. The position giving slot 47 is used to give position to the clamping assembly 35, so that the clamping assembly 35 can better clamp the metal block On the turnover plate 42, a falling prevention assembly 45 is fixedly installed. The core component of the falling prevention assembly 45 is a falling prevention frame 451. The falling prevention frame 451 is welded on the turnover plate 42 and is vertically arranged on the turnover plate 42, thereby providing a mounting basis for other components of the falling prevention assembly 45.

[0025] On the falling prevention frame 451, a plurality of guide rods 452 are slidingly arranged. The guide rods 452 can freely slide in the falling prevention frame 451 along a straight line direction. One end of the guide rod 452 is fixedly connected with a falling prevention baffle 453, and the falling prevention baffle 453 is slidingly arranged in the falling prevention frame 451. When the guide rod 452 slides in the falling prevention frame 451, the falling prevention baffle 453 is driven to move together. The falling prevention baffle 453 is used to block the opening of the limiting frame 44 under certain conditions, thereby preventing the metal block from falling from the opening of the limiting frame 44.

[0026] On the falling prevention frame 451, a trigger rod 454 is also rotationally arranged. The trigger rod 454 can rotate about the connecting point between the trigger rod 454 and the falling prevention frame 451. One end of the trigger rod 454 is fixedly provided with a trigger sliding block 455. The falling prevention frame 451 is provided with an arc-shaped slot 456, and the falling prevention baffle 453 is provided with a straight slot 457. The trigger sliding block 455 is located in the arc-shaped slot 456 and the straight slot 457 at the same time. When the trigger rod 454 rotates, the trigger sliding block 455 slides in the arc-shaped slot 456 and the straight slot 457, thereby achieving control over the movement of the falling prevention baffle 453.

[0027] On the bracket 1, a trigger stop rod 458 is fixedly arranged. When the turnover plate 42 is in the initial position, the trigger rod 454 and the trigger stop rod 458 are in contact with each other. A tension spring 459 is sleeved on the guide rod 452. One end of the tension spring 459 is fixed on the falling prevention frame 451, and the other end is fixed on the end of the guide rod 452. The tension spring 459 is used to provide a pulling force for the guide rod 452. As shown in Figure 8 When the trigger rod 454 and the trigger stop rod 458 are out of contact, the tension spring 459 pulls the guide rod 452 to move, thereby driving the falling prevention baffle 453 to extend and block the opening of the limiting frame 44, thereby preventing the metal block from falling.

[0028] As shown in Figure 7 When the turnover plate 42 is reset, i.e., the turnover telescopic cylinder 43 is retracted, the trigger rod 454 cooperates with the trigger stop rod 458, the trigger rod 454 rotates, drives the trigger sliding block 455 to move, and the trigger sliding block 455 drives the falling prevention baffle 453 to be retracted into the falling prevention frame 451 through the straight slot 457, In the device, a material blocking assembly 5 is also arranged, and the main component of the material blocking assembly 5 is a material blocking plate 51. The material blocking plate 51 is slidingly arranged on the support 1 and located between the conveying assembly 2 and the overturning assembly 4.

[0029] On one side of the rotating shaft 41, a gear 52 is fixedly installed. On the material blocking plate 51, a rack 53 is fixedly arranged, and the rack 53 is in meshing connection with the gear 52 on the rotating shaft 41. When the rotating shaft 41 rotates, the gear 52 will rotate together, and the rotation of the gear 52 will drive the rack 53 in meshing connection with the gear 52 to move, so that the material blocking plate 51 slides in the sliding groove on the support 1 in the vertical direction.

[0030] The material blocking plate 51 is slidingly arranged through the sliding groove on the support 1, and the sliding groove provides guidance and limitation for the sliding of the material blocking plate 51, so as to ensure that the material blocking plate 51 can only move in the vertical direction. Such a design enables the material blocking plate 51 to rise when needed to block the subsequent metal block and prevent it from falling, and to descend when not needed without affecting the normal conveying of the metal block.

[0031] In the device, the grabbing assembly 3 undertakes the function of transferring the overturned metal block to the smelting furnace, and the core supporting component of the grabbing assembly 3 is a grabbing arm 31. The grabbing arm 31 is installed on the support 1 in a fixed connection manner to form a stable overall structure with the support 1, thereby providing a reliable foundation for the installation and movement of subsequent components.

[0032] The support plate 32 is slidingly assembled on the grabbing arm 31 and can smoothly slide along the length direction of the grabbing arm 31. In order to drive the support plate 32 to move, a horizontal telescopic cylinder 33 is fixedly installed on the grabbing arm 31, the cylinder body part of the horizontal telescopic cylinder 33 is fixedly connected with the grabbing arm 31, and the telescopic movable end is fixedly connected with the support plate 32. When the horizontal telescopic cylinder 33 is started and performs the telescopic action, the movable end will directly drive the support plate 32 to slide in the horizontal direction on the grabbing arm 31, so as to adjust the horizontal position of the support plate 32 and subsequent components.

[0033] The vertical telescopic cylinder 34 is fixedly arranged on the support plate 32, the cylinder body of the vertical telescopic cylinder 34 is fixedly connected with the support plate 32 to ensure that the support plate 32 can be synchronously followed when the support plate 32 moves. The movable end of the vertical telescopic cylinder 34 faces downward, and the clamping assembly 35 is fixedly installed on the movable end. When the vertical telescopic cylinder 34 performs the telescopic action, the movable end will drive the clamping assembly 35 to move in the vertical direction, so as to adjust the height of the clamping assembly 35, so that the clamping assembly 35 can accurately align the metal block to be grabbed, or lift the metal block to a suitable height after grabbing for transfer.

[0034] Through the connection structure, the actions of the horizontal telescopic cylinder 33 and the vertical telescopic cylinder 34 are coordinated with each other, so that the horizontal position and the vertical height of the clamping assembly 35 can be flexibly adjusted, thereby ensuring that the clamping assembly 35 can accurately reach the position of the metal block to complete the grabbing and be smoothly transferred to above the smelting furnace.

[0035] The overall structure of the clamping assembly 35 is based on a fixed plate 351, which is installed on the movable end of the vertical telescopic cylinder 34 in a fixed connection manner and moves in the vertical direction synchronously with the action of the vertical telescopic cylinder 34. On the fixed plate 351, a clamping telescopic cylinder 352 is fixedly arranged, and the cylinder body part of the clamping telescopic cylinder 352 is firmly combined with the fixed plate 351 to provide a power source for the entire clamping action.

[0036] One end (non-movable end) of the clamping telescopic cylinder 352 is fixedly connected with a connecting plate 353, and the connecting plate 353 is fixedly connected with the clamping telescopic cylinder 352. A plurality of clamping jaws 354 are rotatably installed on the connecting plate 353, the clamping jaws 354 are symmetrically distributed, and each clamping jaw 354 is connected with the connecting plate 353 through a rotating shaft and can flexibly rotate around the connecting point, thereby realizing the opening and closing action.

[0037] The movable end of the clamping telescopic cylinder 352 is fixedly connected with a pull plate 355, and the pull plate 355 synchronously telescopes with the movable end of the clamping telescopic cylinder 352. The pull plate 355 is connected with each clamping jaw 354 through a connecting rod 356, one end of the connecting rod 356 is rotatably connected with the pull plate 355, and the other end is rotatably connected with the middle part (non-clamping end) of the clamping jaw 354, thereby forming a linkage structure. When the clamping telescopic cylinder 352 is started and performs the telescopic action, the movable end drives the pull plate 355 to move towards or away from the connecting plate 353. When the pull plate 355 moves, the action force is transmitted through the connecting rod 356, so that the clamping jaw 354 is forced to rotate around the connecting point of the connecting plate 353. If the clamping telescopic cylinder 352 is contracted, the pull plate 355 pulls the connecting rod 356, and the clamping jaw 354 rotates inward and closes to realize the clamping of the metal block. If the clamping telescopic cylinder 352 is extended, the pull plate 355 pushes the connecting rod 356, and the clamping jaw 354 rotates outward and opens to complete the release of the metal block.

[0038] To avoid the rotation of the fixed plate 351 driven by the vertical telescopic cylinder 34 (to ensure that the clamping jaw 354 always maintains the symmetric direction and accurately aligns with the metal block), an anti-rotation rod 36 is fixedly arranged at one end of the fixed plate 351. The other end of the anti-rotation rod 36 is slidably arranged on the support plate 32. When the vertical telescopic cylinder 34 drives the fixed plate 351 to ascend and descend, the anti-rotation rod 36 synchronously slides along the preset path on the support plate 32. Through the sliding fit, the rotation freedom of the fixed plate 351 is limited, and the overall posture of the clamping assembly 35 is ensured to be stable.

[0039] Through such a structural design, the clamping assembly 35 can accurately reach the metal block position under the cooperation of the vertical telescopic cylinder 34 and the horizontal telescopic cylinder 33, and the opening and closing of the clamping jaw 354 are realized by the power of the clamping telescopic cylinder 352, so that the grabbing and releasing of the metal block are stably completed, and the posture is stable during the whole process, avoiding deviation caused by rotation.

[0040] Workflow and principle The operator first places the metal block to be smelted on the roller conveyor, and the roller conveyor is started to convey the metal block. When the metal block is queued on the roller conveyor to reach the position of the turnover plate 42, the metal block no longer moves due to the limitation of the limiting frame 44, realizing the positioning of the metal block on the turnover plate 42.

[0041] At this time, the turnover telescopic cylinder 43 is started (which can be controlled by a PLC program according to actual conditions), and the turnover telescopic cylinder 43 is extended to drive the turnover plate 42 to rotate 90 degrees around the rotating shaft 41. During the turnover process, since one end of the limiting frame 44 is open, there is a risk of falling during the turnover process, so the anti-falling assembly 45 is provided.

[0042] During the rotation of the turnover plate 42, the trigger rod 454 will be separated from the trigger stop rod 458. When separated, the tension spring 459 will contract to drive the guide rod 452 to move, and the guide rod 452 will drive the anti-falling baffle 453 to extend from the anti-falling frame 451, so that the anti-falling baffle 453 blocks the opening of the limiting frame 44, preventing the metal block from falling during the rotation of the turnover plate 42.

[0043] During the rotation of the turnover plate 42, since the roller conveyor is still moving, the material blocking assembly 5 is provided. The gear 52 of the material blocking assembly 5 rotates synchronously when the rotating shaft 41 rotates, the gear 52 drives the rack 53 to move, and the rack 53 drives the material blocking plate 51 to rise to block the subsequent metal block, preventing it from falling. In the normal state, i.e. when the turnover assembly 4 is not turned over, the material blocking plate 51 is lower than the height of the roller of the roller conveyor, and does not affect the transportation of the metal block.

[0044] When the turnover is in place, i.e. the metal block is in a vertical state, the vertical telescopic cylinder 34 is extended, and the horizontal telescopic cylinder 33 is telescoped, so that the clamping assembly 35 reaches the position of the vertical metal block. Then the clamping telescopic cylinder 352 is retracted, and through the pull plate 355 and the connecting rod 356, the clamping jaw 354 is driven to clamp the metal block.

[0045] Then the horizontal telescopic cylinder 33 is extended to move the metal block above the furnace, and then the clamping telescopic cylinder 352 is extended to release the metal block into the furnace for melting.

[0046] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described. It is intended, therefore, to cover all modifications and adaptions that fall within the scope of the claims and their equivalents.
