[0040] Casting is an important part in the industrial silicon smelting process. The liquid silicon produced by the submerged arc furnace is transported to the casting station in a silicon ladle. After the ingot mold trolley moves to the designated position at the casting station, the staff slowly pours the liquid silicon into the ingot mold on the ingot mold trolley. After the liquid silicon is completely cooled in the ingot mold, the finished industrial silicon is obtained. After the liquid silicon is poured into the ingot mold, the ingot mold trolley needs to move from the casting station to the designated cooling area for cooling the liquid silicon. As one ingot mold trolley leaves the casting station, the next ingot mold trolley will timely move to the casting station for pouring the liquid silicon, and so on for cyclic operation. This cyclic operation mode not only improves the production efficiency, but also reduces the waiting time of equipment and personnel, ensuring the continuity of the entire smelting process.

[0041] Although the current casting process of industrial silicon is relatively perfect, however, through the applicant's research, it is found that since the weight of the ingot mold cart carrying the ingot mold is very high after being filled with molten silicon, during the transportation of the ingot mold cart, it is easy to cause personal injuries such as rolling and collision. At the same time, if the ingot mold cart is transported through the track and there are sundries such as steel pipes on the track, it may cause the derailment or even overturning of the ingot mold cart, resulting in the spilling of molten silicon. This will not only cause a large loss of molten silicon, but also be extremely dangerous for the on-site workers. At present, most industrial silicon factories set up fences around the track of the ingot mold cart to prevent people from entering. This setting controls people's unsafe behaviors to a certain extent, but in case of an emergency, such as the presence of sundries on the forward track, relying solely on the reaction speed of the driver cannot avoid the occurrence of accidents, so the intrinsic safety of the ingot mold cart during the transportation of liquid silicon cannot be achieved.

[0042] In view of this, it is necessary to propose an ingot mold cart 100 to solve the above technical problems.

[0043] Please refer to Figure 1 With Figure 2 , in an embodiment of the present utility model, the ingot mold cart 100 includes a frame 1, an ingot mold 2, a walking member 3, a braking device 4, a detection device 5 and a control device. Among them, the ingot mold 2 is installed on the frame 1, the walking member 3 is installed at the bottom of the frame 1, the braking device 4 is installed on the frame 1 and is located on one side of the walking member 3, the detection device 5 is installed on the frame 1 and is used to detect whether there are obstacles around the ingot mold cart 100, and both the detection device 5 and the braking device 4 are electrically connected to the control device.

[0044] Specifically, the frame 1, as the overall support of the ingot mold car 100, is made of materials with relatively high strength such as section steel, square steel, and aluminum alloy, and is used to carry and install the rest of the devices. In this embodiment, an ingot mold 2 is installed above the frame 1. The ingot mold 2 is formed with an ingot mold 2 cavity for carrying liquid silicon. The liquid silicon is cast into the ingot mold 2 cavity and gradually cools therein, and finally the finished industrial silicon is formed. The shape and size of the finished industrial silicon are related to the shape and size of the ingot mold 2 cavity. A walking member 3 is installed at the bottom of the frame 1. The walking member 3 makes the lowest end of the frame 1 higher than the track or the ground, and is used to support the frame 1 to walk on the track or the ground. A braking device 4 is installed on the frame 1 on one side of the walking member 3. The braking device 4 is used to brake the walking member 3, so that the entire ingot mold car 100 stops moving. The braking device 4 can quickly stop the operation of the walking member 3 when needed, ensuring the transportation safety of the ingot mold car 100. A detection device 5 is also installed on the frame 1. The detection device 5 is mainly used to detect whether there are workers around the ingot mold car 100 when it moves and whether there are parts or other sundries on the forward track. The detection device 5 is connected to the control device by a cable, and at the same time, the control device is also connected to the braking device 4 by a cable. The detection device 5 can transmit an electrical signal to the control device through the cable, and the control device can control whether the braking device 4 brakes the walking member 3 through the cable. In one case, when the detection device 5 detects an obstacle or a worker in the forward direction of the ingot mold car 100, the detection device 5 will send the detection result to the control device in real time. After processing the detection result, the control device will send an electrical signal to the braking device 4 in time to start the braking device 4, so that the braking device 4 brakes the walking member 3, and then the ingot mold car 100 completes braking. Among them, the control device includes one of a microcontroller and a PLC.

[0045] In the embodiment provided by the present utility model, the ingot mold car 100 includes a frame 1, an ingot mold 2, a walking member 3, a braking device 4, a detection device 5, and a control device. Among them, the ingot mold 2 is installed on the frame 1; the walking member 3 is installed at the bottom of the frame 1; the braking device 4 is installed on the frame 1 and is located on one side of the walking member 3; the detection device 5 is installed on the frame 1 and is used to detect whether there are obstacles around the ingot mold car 100; both the detection device 5 and the braking device 4 are electrically connected to the control device. Through this setting, when the ingot mold car 100 carries liquid silicon and moves, the detection device 5 can timely detect whether there are obstacles around the ingot mold car 100. If there are obstacles, it will send an electrical signal to the control device, and the control device will timely control the braking device 4 to brake the walking member 3, so as to achieve the effect of automatic braking and avoid colliding with obstacles or workers and causing danger. This setting changes the prevention of transportation hazards during the transportation process of the ingot mold car 100 from "human prevention" to "technical prevention", thus realizing the intrinsic safety of the transportation process.

[0046] Further, in an embodiment of the present utility model, the number of the detection devices 5 is at least two. Please refer to Figure 1 , in this embodiment, two detection devices 5 are provided and are respectively arranged on both sides of the vehicle frame 1. This arrangement can increase the detection range, ensure the detection range of the ingot mold car 100 during movement, and further reduce the occurrence probability of transportation accidents. On the other hand, through this arrangement, when one of the detection devices 5 fails, the other detection device 5 can still work normally, thereby improving the reliability and safety of the ingot mold car 100. In other embodiments, the number of the detection devices 5 can be set to multiple, such as setting four detection devices 5, with two detection devices 5 respectively arranged on both sides of the vehicle frame 1 and the detection devices 5 being distributed at different heights of the vehicle frame 1, so as to achieve three-dimensional detection and better identify obstacles at different heights.

[0047] In an embodiment of the present utility model, the vehicle frame 1 includes a housing 11, and the detection device 5 is installed at the bottom of the housing 11. Specifically, please refer to Figure 2 , the outermost side of the vehicle frame 1 is provided with a housing 11, and the housing 11 is used to protect the traveling member 3, the control device and the rest of the structure of the vehicle frame 1. At the bottom of the vehicle frame 1, near the traveling member 3, the detection device 5 is installed. The installation method of the detection device 5 and the housing 11 includes one of snap connection, bolt connection, and sliding buckle connection, and even welding connection can be adopted. Since the main reason for the tipping accident of the ingot mold car 100 during transportation is that small parts are scattered on the transportation track, when the ingot mold car 100 rolls over these small parts, the center of gravity becomes unstable, and finally the ingot mold car 100 tips over. Therefore, through this arrangement, the detection device 5 can more effectively detect obstacles close to the ground, such as small parts and low obstacles, so as to take measures in advance and reduce the risk of the ingot mold car 100 tipping over.

[0048] Further, please refer to Figure 4, in an embodiment of the present utility model, the outer shell 11 includes a receiving portion 111 which protrudes outwardly towards the outside of the outer shell 11, and the receiving portion 111 is formed with a mounting groove 1112 having an opening 1111 facing the inside of the outer shell. A detection hole is provided in the mounting groove 1112. The detection device 5 includes a detection head. The detection device 5 is installed in the mounting groove 1112, and the detection head is disposed in the detection hole. Specifically, the outer shell 11 includes an inner wall 113 and an outer wall 112. The inner wall 113 is located on the side where the walking member 3 is installed, and the outer wall 112 is disposed opposite to the inner wall 113. At the installation position of the detection device 5, the outer shell 11 protrudes from the direction of the inner wall 113 towards the direction of the outer wall 112, and a mounting groove 1112 similar in size to the detection device 5 is formed on the side of the inner wall 113. The detection device 5 can be installed in the mounting groove 1112 so that the outer shell 11 can cover the side of the detection device 5 close to the outer wall 112 of the outer shell 11, thereby providing additional physical protection for the detection device 5 and reducing the risk of damage caused by collision or environmental factors. At the same time, this design provides a simple appearance design and increases the overall aesthetics of the ingot mold car 100. In addition, in order not to block the detection head of the detection device 5 by the outer shell 11, a detection hole is provided at a suitable position in the mounting groove 1112, and the detection head is installed in the detection hole to avoid affecting the detection function of the detection device 5.

[0049] In an embodiment of the present utility model, the detection device 5 includes at least one of an infrared range finder, an ultrasonic sensor, and a radar sensor. In one embodiment, the detection device 5 only uses an infrared range finder to measure the distance data information in the forward direction when the ingot mold car 100 moves through infrared rays, and sends the detection result to the control device. A minimum distance value is preset in the control device. When the distance detected by the infrared range finder is less than or equal to the minimum distance value, the control device sends an electrical signal to the braking device 4 to brake the ingot mold car 100. In another embodiment, the detection device 5 uses an infrared range finder and an ultrasonic sensor, so that the detection device 5 integrates the advantages of both. The infrared range finder performs well under low light conditions, while the ultrasonic sensor has better effects in a dusty environment. Combining the two can improve the environmental adaptability of the ingot mold car 100, enabling the ingot mold car 100 to work effectively under various environmental conditions.

[0050] In an embodiment of the present utility model, the ingot mold car 100 further includes an audible and visual alarm device 6. The audible and visual alarm device 6 is installed outside the vehicle frame 1 and is electrically connected to the control device. As Figure 1 and Figure 2, an audible and visual alarm device 6 is provided on the outer side of the frame 1. This device can emit sound and light according to the control. The audible and visual alarm device 6 includes one of an industrial audible and visual alarm or an LED audible and visual alarm. The industrial audible and visual alarm has the advantages of high volume, strong light penetration, high reliability, etc., while the LED audible and visual alarm has the characteristics of low power consumption and long life. When designing the ingot mold car 100, it can be selected according to the actual situation. By installing the audible and visual alarm device 6 on the outer side of the frame 1 of the ingot mold car 100 and electrically connecting the audible and visual alarm device 6 to the control device, when there is an obstacle in the forward direction of the ingot mold car 100, the ingot mold car 100 can be braked in time, and at the same time, the audible and visual alarm device 6 emits an alarm sound and light, which can more effectively remind people or vehicles around to pay attention to the running state of the ingot mold car 100 to avoid accidents.

[0051] In an embodiment of the present utility model, the frame 1 includes a lead pipe. The lead pipe includes a cavity. The control device is connected to the braking device 4 and the detection device 5 through a cable. The cable is arranged in the cavity. Specifically, the lead pipe includes a pipe wall, and the pipe wall encloses a cavity. The cable can extend along the length direction of the cavity, so that the cable can be wrapped in the pipe wall. Since the cables of the detection device 5 and the braking device 4 are both arranged at the bottom of the frame 1, it is possible that the cables may be scratched or crushed. By arranging a lead pipe in the frame 1 and arranging the cable in the cavity of the lead pipe, the cable will not drop to the ground as the use time increases, thereby avoiding the risk that the cable may be scratched or crushed, reducing the risk of open circuit and short circuit, and further improving the safety of the ingot mold car 100 during use. On the other hand, the layout of the cable in the cavity makes the outside of the frame 1 more tidy, avoids the cables being in a mess, and improves the overall aesthetics of the ingot mold car 100.

[0052] In an embodiment of the present utility model, the frame 1 includes a coupling shaft 12. The traveling member 3 is installed on the coupling shaft 12. Two traveling members 3 are installed on one coupling shaft 12, and the two traveling members 3 are symmetric about a plane passing through the center of the coupling shaft 12 and perpendicular to the central axis of the coupling shaft 12. Specifically, please refer to Figure 1 , the coupling shaft 12 is located at the bottom of the whole frame 1 and is used to install the traveling member 3. The number of traveling members 3 on each coupling shaft 12 is two, and the two traveling members 3 are symmetrically arranged. The symmetry plane is a plane passing through the center of the coupling shaft 12 and perpendicular to the central axis of the coupling shaft 12. Through this setting, the ingot mold car 100 can maintain balance and reduce the risk of vehicle rollover.

[0053] Furthermore, the braking device 4 is installed between the center of the coupling shaft 12 and the traveling member 3. As Figure 2As shown, in this embodiment, the braking device 4 is installed close to the walking member 3 and is located on the side of the walking member 3 close to the center of the coupling shaft 12. This setting makes the braking device 4 relatively less vulnerable to direct impact from external objects and reduces the risk of damage. At the same time, in this embodiment, the number of braking devices 4 is two. The left braking device 4 is arranged on the right side of the left walking member 3, and the right braking device 4 is arranged on the left side of the right walking member 3. This setting can improve the braking effect and reduce the braking distance.

[0054] Specifically, please refer to Figure 3 , the braking device 4 specifically includes a brake disc 41, a brake disc connecting member 42, a brake caliper 43, brake pads 44, a hydraulic cylinder 45, a hydraulic pipe 46, and a solenoid valve. Among them, the brake disc connecting member 42 is used to connect the brake disc 41 and the coupling shaft 12, and the brake disc 41, the coupling shaft 12, and the walking member 3 start and stop synchronously; the brake caliper 43 includes a first pressure cylinder 431 and a second pressure cylinder 432. The first pressure cylinder 431 is located on one side of the brake disc 41, and the second pressure cylinder 432 is located on the other side of the brake disc 41; the brake pads 44 are arranged on the inner side of the brake caliper 43 facing the brake disc 41; the hydraulic cylinder 45 is communicated with the first pressure cylinder 431 and the second pressure cylinder 432; the hydraulic pipe 46 is communicated with the hydraulic cylinder 45; the solenoid valve is communicated with the hydraulic pipe 46 and is electrically connected to the control device. After receiving the electrical signal from the control device, the solenoid valve opens the valve, allowing hydraulic oil to enter the hydraulic pipe 46 through the valve and then enter the hydraulic cylinder 45. The hydraulic cylinder 45 is communicated with the first pressure cylinder 431 and the second pressure cylinder 432, and a clamping space is formed between the first pressure cylinder 431 and the second pressure cylinder 432. As the hydraulic oil enters the brake caliper 43, the distance between the first pressure cylinder 431 and the second pressure cylinder 432 gradually decreases, causing the brake pads 44 to gradually clamp the brake disc 41, thereby gradually stopping the rotation of the brake disc 41. Since the brake disc 41 and the walking member 3 start and stop synchronously, the walking member 3 also gradually stops rotating, and at this time, the braking process of the ingot mold car 100 is completed.

[0055] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
