[0050] like Figures 1 to 4 As shown, the utility model proposes a ladle 2 drainage sand system, see Figure 1 and Figure 2 , including a frame 1, a ladle 2, a feeding mechanism 3, a hoisting mechanism 4 and a positioning mechanism 5.

[0051] The frame 1 has a base 11 and a support platform 12 supported on the base 11. The base 11 is provided with a mounting position 13, and the support platform 12 has a hollow area 14 corresponding to the mounting position 13; the ladle 2 can be horizontally movably arranged on the base 11, and can be in the mounting position 13 in its movable stroke.

The funnel 41 is arranged on the support platform 12, and the upper end of the funnel 41 is arranged corresponding to the lower end of the drainage sand pipe 31, so that the drainage sand The tube 31 is connected to the funnel 41, and the lower end of the funnel 41 corresponds to the hollow area 14. The lifting rope 42 is connected to the funnel 41 for lifting or lowering the funnel 41, so that the lower end of the funnel 41 is inserted into the inlet of the ladle 2 through the hollow area 14 or is withdrawn from the inlet of the ladle 2; and the positioning mechanism 5. The positioning mechanism 5 includes a positioning frame 52 and a positioning drive device 51. The positioning frame 52 is movably arranged and can be moved to the hollow area 14, so that the lower end of the funnel 41 can pass through the positioning frame 52 and be inserted into the inlet of the ladle 2, so that the lower end of the funnel 41 can be limited around the side by the positioning frame 52, and the positioning drive device 51 drives the positioning frame 52 to be movably arranged, so as to be able to drive the positioning frame 52 to be placed in the hollow area 14.

[0052] The technical solution of the utility model is to set a positioning frame 52 and a positioning drive device 51 on the frame 1, and use the positioning drive device 51 to drive the movement of the positioning frame 52, so that the positioning frame 52 moves to the hollow area 14, and then the lifting rope 42 of the hoisting mechanism 4 is used to make the lower end of the funnel 41 pass through the positioning frame 51 and the hollow area 14, and insert into the inlet of the ladle 2, so that the drainage sand in the drainage sand pipe 31 enters the ladle 2 through the funnel 41, and the positioning frame 52 circumferentially limits the lower end of the funnel 41, and finally avoids the shaking of the drainage sand pipe 31 during the hanging process, and prevents it from being misaligned with the inlet of the ladle 2, so that the drainage sand can be better filled into the inlet of the ladle 2, and the drainage sand is evenly laid inside the ladle 2, thereby improving the quality of the product.

[0053] like Figure 1 and Figure 2 As shown, specifically, in this embodiment, a steel rail leading to the mounting position 13 of the base 11 is laid on the ground, a ladle car is driven on the steel rail, and the ladle 2 is mounted on the ladle car for movement. In other embodiments, a mounting frame is provided on the support platform 12, and the drainage sand pipe 31 is connected to the support platform 12 through the mounting frame. The mounting frame increases the installation height of the drainage sand pipe 31 so that the drainage sand can be more stably injected into the ladle 2 from above the funnel 41.

[0054] In other embodiments, it can be further configured that the positioning drive device 51 includes an X-axis guide rail, an X-axis slider, an X-axis driver, a Y-axis guide rail, a Y-axis slider and a Y-axis driver, the X-axis rail is installed on the support table 12; the X-axis slider is slidably arranged on the X-axis guide rail; the X-axis driver is installed on one side of the X-axis guide rail, and the X-axis driver drives the X-axis slider to move along the X-axis guide rail; the Y-axis guide rail is installed on the X-axis slider; the Y-axis slider is slidably arranged on the Y-axis guide rail, and the positioning frame 52 is installed on the Y-axis slider and moves with the Y-axis slider; and the Y-axis driver is installed on one side of the Y-axis guide rail, and the Y-axis driver drives the Y-axis slider to move along the Y-axis guide rail.

[0055] Specifically, in this embodiment, the X-axis driver can be driven by a cylinder to make the X-axis slider move linearly on the X-axis guide rail, and the Y-axis driver can be driven by a cylinder to make the Y-axis slider move linearly on the Y-axis guide rail;

[0056] In order to better improve the adjustment accuracy, the X-axis driver can also use a rotating motor. An X-axis lead screw that rotates coaxially with the rotating motor is installed at the output end of the rotating motor. The X-axis lead screw extends in the length direction of the X-axis guide rail. A corresponding threaded hole is provided at the position of the X-axis corresponding to the X-axis lead screw. When the rotating motor rotates, the X-axis lead screw can rotate, thereby moving the X-axis slider on the X-axis guide rail. The Y-axis driver can adopt the same method, and no unnecessary details will be given here.

[0057] The angle between the X-axis and the Y-axis can be set arbitrarily when they are not parallel. In this embodiment, it is preferably 90°. In this way, the X-axis slider and the Y-axis slider form a rectangular coordinate system, which improves the visualization and facilitates calculation and derivation.

[0058] In other embodiments, it can be further configured that the ladle 2 drainage sand system also includes a detection proximity switch 7, an image identifier 6 and a control device: the detection proximity switch 7 is installed on the support table 12 and is set corresponding to the mounting position 13, so as to be triggered when the ladle 2 is in the mounting position 13; it is installed on the support table 12 and is set corresponding to the mounting position 13, so as to photograph the position of the ladle 2 and the feed port when the ladle is in the mounting position 13; it is electrically connected to the detection proximity switch 7, the image identifier 6 and the positioning drive device 51, so as to control the positioning drive device 51 to work according to the signals of the detection proximity switch and the image identifier 6.

[0059] Specifically, in this embodiment, the image recognizer 6 is located on one side of the positioning drive device 51 , and a clearance hole is opened on the support platform 12 corresponding to the recognition area of ​​the image recognizer 6 to avoid blocking the recognition area of ​​the image recognizer 6 and thus affecting the operation of the image recognizer 6 .

[0060] Controlling the driving of the positioning drive device 51 by a control device is an existing control method. In this embodiment, the focus is on using the control device to facilitate the control of the positioning drive device 51, reduce human operation, facilitate rapid docking, and improve production efficiency. In addition, the control device can also be electrically connected to other electrical appliances, so that multiple electrical appliances can be coordinated and managed, further reducing human operation or even realizing unmanned operation, greatly improving production efficiency.

[0061] like Figure 4 As shown, in other embodiments, the hoisting mechanism 4 also includes a pulley 43 and a rotating motor 44. The pulley 43 stands on the support platform 12. The middle section of the lifting rope 42 is wound around the pulley 43, one end of which is fixedly connected to the funnel 41, and the other end is fixedly connected to the rotating end of the rotating motor 44. The pulley 43 is configured to change the force of the lifting rope 42. The rotating motor 44 is installed on the support platform 12, and the lifting rope 42 can be retracted or released when the rotating motor 44 rotates.

[0062] In this way, the lifting rope 42 is wound in or out of the output shaft of the rotating motor 44 by rotating the output shaft of the rotating motor 44 counterclockwise or clockwise, thereby changing the length of the lifting rope 42 between the rotating motor 44 and the funnel 41, thereby controlling the distance of the funnel 41 relative to the ladle 2, and allowing the funnel 41 to be inserted into or withdrawn from the ladle 2. The pulley 43 can change the force direction of the lifting rope 42, thereby lowering the setting position of the rotating motor 44 for easy installation.

[0063] In other embodiments, the hoisting mechanism 4 further includes a support 45 , the support 45 is erected on the support platform 12 , and the pulley 43 is rotatably mounted on one end of the support 45 away from the support platform 12 .

[0064] Specifically, the support 45 is vertically arranged so that the height of the pulley 43 relative to the ground is greater than the height of the rotating motor 44 relative to the ground, so that the angle formed by the lifting ropes 42 on both sides of the pulley 43 is less than 90°, thereby facilitating the installation position of the rotating motor 44.

[0065] It can be further configured that the feeding mechanism 3 also includes a silo 32, a hopper 33 and a valve 34, the silo 32 stands on the support platform 12; the hopper 33 is arranged below the silo 32, and the lower end of the hopper 33 is connected to the drainage sand pipe 31; the valve 34 is arranged in the hopper 33, and the valve 34 opens and closes the hopper 33.

[0066] Specifically, the silo 32 is mounted on the top of the mounting frame, so as to give the drainage sand enough gravitational potential energy so that it can be converted into kinetic energy during the falling process and spontaneously fall into the ladle 2 to complete the loading. The upper and lower parts of the silo 32 have openings, and the upper opening is larger than the lower opening. The upper opening is convenient for rapid loading, and the lower opening is convenient for slow discharge to match the speed of material transportation. The bottom of the silo 32 corresponds to the feed port of the hopper 33, so as to receive the drainage sand falling from the silo 32 and play a transition role. The type of valve 34 is not currently limited, and it can be used to open or close the space in the hopper 33. In order to reduce personnel operation and improve operating efficiency, in this embodiment, a pneumatic discharge valve is adopted, and the pneumatic discharge valve can be electrically connected to the control device, so as to facilitate the control of whether the hopper 33 is to discharge.

[0067] In other embodiments, it can be further configured that the feeding mechanism 3 also includes a vibrating feeder 35, the vibrating feeder 35 is installed above the hopper 33, and the vibrating feeder 35 is configured to vibrate the drainage sand dropped from the silo 32 to transfer it to the hopper 33.

[0068] In this way, the vibrating feeder 35 can provide the drainage sand uniformly and control the conveying amount. The vibration force of the vibrating feeder 35 can destroy the adhesion between the drainage sands and prevent the drainage sands from piling up and clogging during the conveying process. It can effectively handle some materials that are easy to agglomerate and stick together, improve the fluidity and conveying effect of the drainage sand, and improve production efficiency and product quality.

[0069] In other embodiments, it can be further configured that the feeding mechanism 3 also includes a weighing sensor 36, and the weighing sensor 36 is installed below the hopper 33, and the weighing sensor 36 is configured to weigh the drainage sand in the hopper 33.

[0070] In this way, the drainage sand used in general production is packed with a fixed weight in bags. However, with the production of different types of steel in metallurgy, it is necessary to adjust the amount of drainage sand process parameters added, and the amount added needs to be accurately measured. In this embodiment, a weighing sensor 36 is designed for drainage sand during the downward process of the material, which can accurately measure the process parameters for adding drainage sand.

[0071] In other embodiments, it can be further configured that the feeding mechanism 3 also includes a grid screen, the grid screen is arranged at the upper port of the hopper 33, and the grid screen is configured to screen the drainage sand falling into the hopper 33 from the silo 32.

[0072] In this way, when the drainage sand is stored for too long on site and large pieces of slagging materials are filtered, the large pieces of drainage sand can be supported by the grid screen to prevent them from falling into the hopper 33, so that manual intervention can be performed to avoid the occurrence of downward obstruction of conveying materials due to the drainage sand material being stored for too long.

[0073] In other embodiments, it can be further configured that the feeding mechanism 3 also includes a swinging cylinder 37 and a connecting rod 38, the swinging cylinder 37 stands on the support platform 12, one end of the connecting rod 38 is connected to the drainage sand pipe 31, and the other end of the connecting rod 38 is connected to the output end of the swinging cylinder 37, so that the swinging cylinder 37 drives the drainage sand pipe 31 to swing via the connecting rod 38.

[0074] In this way, the funnel 41 is prevented from colliding with the drainage sand pipe 31 during the lifting process. The swing cylinder 37 drives the connecting rod 38 to rotate to make the drainage sand swing, thereby moving the drainage sand pipe 31 away from the top of the funnel 41, thereby avoiding interference with the lifting of the funnel 41.

[0075] The workflow of the technical solution of the utility model is as follows:

[0076] The first step is to detect whether the proximity switch 7 detects whether the ladle 2 is in place, if yes, proceed to the second step, otherwise proceed to the sixth step;

[0077] In the second step, the image recognizer 6 detects whether there is a foreign object in the inlet of the ladle 2. If yes, the process proceeds to the third step, the rotating motor 44 works to make the funnel 41 drop and insert into the ladle 2. When the bottom of the funnel 41 is a certain distance away from the inlet of the ladle 2, the process proceeds to the third step. Otherwise, an alarm is issued for manual processing.

[0078] In the third step, the positioning drive device 51 detects the inlet of the ladle 2 with the help of the image recognition device 6 to guide the bottom of the funnel 41 to vertically insert into the inlet of the ladle 2, and then proceed to the fourth step;

[0079] In the fourth step, the image recognizer 6 confirms that the bottom of the funnel 41 is inserted into the feeding port of the ladle 2 (the rotating motor 44 and the positioning drive device 51 both stop working), and then proceeds to the fifth step;

[0080] Step 5: The swing cylinder 37 is started to align the drainage sand pipe 31 with the funnel 41, and then the sixth step is entered;

[0081] Step 6: Add drainage sand, and start the vibrating feeder 35 to feed the intermediate hopper 33 with drainage sand of the required weight (the weight of the drainage sand is determined according to the process requirements); open the valve 34, and the drainage sand enters the funnel 41 through the drainage sand pipe 31 (the valve 34 is automatically closed after waiting for a certain period of time), and then enter the seventh step;

[0082] Step 7: The motor 44 is turned to start the funnel 41 and then the eighth step is entered.

[0083] In the eighth step, the image recognizer 6 recognizes whether there is a problem in adding the drainage sand. If yes, an alarm is given and a manual check is performed to confirm. Otherwise, the device is on standby and waits for the next operation.

[0084] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
