Description

Technical Field

[0001] The utility model relates to the field of orbital pouring machines, and particularly relates to a high-safety orbital pouring machine. Background Technique

[0002] The orbital pouring machine is a piece of equipment used in casting production. It generally runs along a preset track and can accurately and quantitatively pour molten metal materials into the mold. The orbital pouring machine has the advantages of stable and accurate pouring process, and can effectively control the pouring speed and flow rate, which helps to improve the quality and yield of castings. Its structure usually includes a traveling mechanism, a pouring mechanism (such as a ladle, a nozzle, etc.) and a control system. With precise control and stable operation, it can adapt to molds of different specifications and shapes and plays an important role in the casting industry.

[0003] Since the metal melting and casting belongs to a special industry, safety issues need to be paid attention to at all times, and any safety details need to be considered. However, there are still some deficiencies in the current conventional orbital pouring machines in actual use, which may lead to safety accidents. First, there is only one safety protection for the tilting drive device of the ladle. Once it fails, the ladle will get out of control and cause safety accidents. Second, there is no real-time temperature monitoring for the ladle, which cannot prevent abnormal situations. And when the temperature in the ladle is found to be too high, there is no timely cooling measure, resulting in the failure to eliminate safety hazards in time. Finally, there is no real-time full-process limit monitoring for the tilting of the ladle. There are only limit detection points at the head and tail, and the tilting angle and speed of the ladle cannot be controlled, resulting in safety accidents caused by non-standard operations. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a high-safety orbital pouring machine, which can effectively solve the problems mentioned in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A high-safety orbital pouring machine includes a driving box, a driven box, and a ladle body installed between the driving box and the driven box. A plurality of temperature sensors are assembled on both sides of the outer shell of the ladle body. Connecting bushings and rotating bushings are respectively arranged on both sides of the ladle body. The connecting bushing is rotatably connected to the driving box, and the rotating bushing is rotatably connected to the driven box. A driving device is installed inside the driving box to connect the connecting bushing and drive the ladle body to rotate. An arc grating ruler is also installed on one side of the outer shell of the ladle body close to the driven box. A grating sensor is also installed on the surface of the driven box corresponding to the position of the arc grating ruler. The grating sensor and the arc grating ruler form a limit structure for the rotation of the ladle body.

[0007] Preferably, the driving box and the driven box are mounted on the track, and a driving mechanism for traveling on the track is provided at the inner bottom end of the driving box.

[0008] Preferably, a casting port that protrudes forward and is closed at the front end of the package body, and a rear baffle that is an integral structure and protrudes above the package body is provided at the rear end of the package body.

[0009] Preferably, the temperature sensors are embedded in the outer shell of the package body and are uniformly arranged from top to bottom.

[0010] Preferably, the driving device mainly consists of a driving motor and a speed reducer. The driving motor and the speed reducer are assembled in a housing, and the housing is fixedly installed on the inner wall of the driving box through bolts. The output end of the speed reducer is fixedly connected to the connecting bushing.

[0011] Preferably, the driving device further includes a brake. The brake is installed on the output shaft of the speed reducer and is linked and controlled with the driving motor.

[0012] Preferably, the central angle corresponding to the arc grating ruler is 90°, and the center is coaxial with the rotating bushing. The grating sensor is always on the rotation trajectory of the arc grating ruler.

[0013] Preferably, the outer shell of the package body is provided with a sandwich layer. A water injection port is provided at the center of the rotating bushing and is communicated with the sandwich layer. A pipeline is provided inside the driven box to supply water to the water injection port. A drain valve is additionally installed at the bottom of the package body.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By adding a brake in the driving device and linking and controlling it with the driving motor, that is, when the driving motor fails or power is cut off and the machine stops, the brake will act to lock the rotating shaft, thereby fixing the package body to prevent it from continuing to rotate or swing back and forth, causing the molten iron inside to splash out and hurt people. When the driving motor is working normally, the brake is released and does not affect normal operation.

[0016] 2. By providing a package body with a sandwich layer structure, and setting a water injection port and a water supply mechanism to add circulating water to the sandwich layer, and the circulating water can be discharged from the drain valve at the bottom of the package body. Cooperating with the temperature sensors uniformly arranged on the package body to monitor the temperature of the package body in real time. Once the temperature exceeds the limit value, cooling water is immediately injected into the sandwich layer for cooling to avoid the phenomenon of scalding people and damaging equipment caused by too high temperature of the package body, leaving enough time for the staff to handle the high temperature phenomenon.

[0017] 3. By setting an arc-shaped grating limit structure, where the arc-shaped grating ruler rotates synchronously with the tilting of the package body, and the grating sensor determines the tilting angle by detecting the scale on the arc-shaped grating ruler. Once the angle is exceeded or the tilting is too fast, the driving motor is immediately stopped and braking is performed in cooperation with the brake, thus forming a double-limit protection.

[0023] To make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the detailed implementation modes.

[0024] As Figure 1 shown, a high-safety track-type pouring machine includes a driving box 1, a driven box 2 and a package body 3 installed between the driving box 1 and the driven box 2. The driving box 1 and the driven box 2 are mounted on the track 4, and a driving mechanism for traveling on the track 4 is provided at the inner bottom end of the driving box 1. The front end of the package body 3 is provided with a pouring port 5 that protrudes forward and is constricted, and the rear end of the package body 3 is provided with a rear baffle 6 of an integral structure and higher than the package body 3.

[0025] As Figures 2 - 3 shown, a number of temperature sensors 7 are assembled on both sides of the outer shell of the package body 3. The temperature sensors 7 are embedded in the outer shell of the package body 3 and are evenly arranged from top to bottom. The outer shell of the package body 3 is provided with a sandwich layer, and a water injection port 15 communicated with the sandwich layer is provided at the center of the rotating bushing 14. A pipeline is provided inside the driven box 2 to supply water to the water injection port 15, and a drain valve is additionally installed at the bottom of the package body 3.

[0026] As Figures 2 - 3As shown, a connecting sleeve 11 and a rotating sleeve 14 are respectively provided on both sides of the package body 3, wherein the connecting sleeve 11 is rotationally connected to the drive box 1, and the rotating sleeve 14 is rotationally connected to the driven box 2. A driving device 8 is installed inside the drive box 1 to connect the connecting sleeve 11 and drive the package body 3 to rotate. The driving device 8 is mainly composed of a driving motor 9 and a reducer 10. The driving motor 9 and the reducer 10 are assembled in a housing, and the housing is fixedly installed on the inner wall of the drive box 1 by bolts. The output end of the reducer 10 is fixedly connected to the connecting sleeve 11. The driving device 8 also includes a brake 12, which is installed on the output shaft of the reducer 10, and the brake 12 is linked with the driving motor 9 for control.

[0027] like Figures 2 - 4 As shown, a curved grating ruler 16 is also installed on the side of the shell of the enclosure 3 close to the driven box 2, and a grating sensor 13 is also installed on the surface of the driven box 2 at a position corresponding to the curved grating ruler 16. The grating sensor 13 and the curved grating ruler 16 form a limit structure for the rotation of the enclosure 3. The central angle of the curved grating ruler 16 is 90°, and the center of the circle is coaxial with the rotating shaft sleeve 14, and the grating sensor 13 is always on the rotation track of the curved grating ruler 16.

[0028] In actual use, the driving box 1 and the driven box 2 carry the ladle 3 and move horizontally on the track 4 to transport the molten iron to the pouring station. The pouring port 5 at the front end of the ladle 3 is for convenient cluster dumping, while the rear baffle 6 at the rear end is to prevent the shaking at the moment of dumping from splashing out and injuring people. When dumping starts, the control system first starts the drive motor 9, and the drive motor 9 then drives the reducer 10. Finally, the reducer 10 is driven to rotate through the connecting sleeve 11 to dump. The brake 12 is linked to the drive motor 9 to keep it in a loose state when the drive motor 9 is working normally. While tipping, since the center of the circle corresponding to the arc grating ruler 16 is coaxial with the rotating sleeve 14 and the connecting sleeve 11, the arc grating ruler 16 rotates synchronously with the bag body 3, and the rotation angles of the two are consistent. At this time, the grating sensor 13 installed on the driven box 2 is always aligned with the arc grating ruler 16, and the tipping angle is determined by detecting the signal fed back by the scale on the arc grating ruler 16. Once the rotation angle is greater than 90° or the angular rotation speed during the tipping process is greater than the set value, the grating sensor 13 immediately feeds back a signal to the control system, cuts off the power to the drive motor 9 and stops it. At the same time, the linkage control is started, and the brake 12 works to lock the output shaft of the reducer 10 to prevent the bag body 3 from continuing to tip over and causing a safety accident.

[0029] During the working process, the temperature sensor 7 monitors the temperatures at different heights inside the ladle body 3 in real time. Once it is found that the temperature at a certain place is too high or continuously rising, it may be that the molten iron temperature is high or the shell of the ladle body 3 is damaged. At this time, a signal is automatically sent to the water supply pipeline inside the driven box 2, and cooling circulating water is injected into the sandwich layer of the ladle body 3 through the water injection port 15. Then, the temperature is continuously monitored. If it is found that the temperature drops to the normal value, the work continues, and after pouring out the molten iron, the ladle body 3 is repaired; if the temperature cannot be lowered in a short time, the drain valve at the bottom of the ladle body 3 is opened to form continuous circulating heat dissipation until the temperature drops. After pouring out the molten iron, the ladle body 3 is repaired to further ensure safety.
