[0027] like Figures 1 to 4 As shown, according to an embodiment of this utility model, a truss-type automatic sand-turning and steel-embedding device is provided, such as... Figure 1 As shown, the system includes a truss crane, an overhead crane, and a grab bucket 10. The overhead crane lifts the steel that needs to be slowly cooled into the sand pit 11. The truss crane is positioned above the sand pit 11. The grab bucket 10 is connected to the truss crane. The truss crane can move the grab bucket 10 in the length, width, and height directions of the sand pit 11. The grab bucket 10 is used to turn the sand, and after turning the sand, it can bury the steel in the sand pit 11.

[0028] Furthermore, the gantry crane includes a trolley rail system, which comprises trolley guide rail 1 and trolley 2, such as... Figure 3 As shown, the trolley guide rail 1 is set along the length of the sand pit 11. There are two trolley guide rails 1, which are respectively set on the ground on both sides of the sand pit 11. The trolley 2 includes a body 12, gantry legs 6 and main beams 3. Each trolley guide rail 1 is equipped with a body 12, and each body 12 is equipped with two gantry legs 6. The lower end of the gantry legs 6 is connected to the body 12. There are two main beams 3, which are set parallel to each other. One end of the main beam 3 is connected to the upper end of one gantry leg 6 on one body 12, and the other end of the main beam 3 is connected to the upper end of one gantry leg 6 on the other body 12.

The trolleys 5 are positioned above the main beams 3, and trolley wheels are provided below the trolleys 5. The trolleys 5 can move on the trolley guide rails via the trolley wheels. The movement of the trolleys 5 on the trolley guide rails can drive the grab bucket 10 to move along the width of the sand pit 11.

[0030] Furthermore, such as Figure 2As shown, the gantry crane also includes a lifting mechanism, which includes a servo motor 7, a support column 8, and a lifting rack 9. The support column 8 is mounted on the trolley 5, the lifting rack 9 is connected to the support column 8, and the grab bucket 10 is connected to the lower end of the lifting rack 9.

[0031] Furthermore, the device also includes an image acquisition mechanism, a control mechanism, a communication and power supply mechanism, and a management system. The image acquisition mechanism and the control mechanism are connected. The control mechanism is connected to both the gantry crane and the grab bucket 10. The control mechanism adjusts the position of the grab bucket 10 in the length and width directions of the sand pit 11 through the trolley track system and the auxiliary track system. The control mechanism also adjusts the position of the grab bucket 10 in the height direction of the sand pit 11 through the lifting mechanism. Under the control of the control mechanism, the grab bucket 10 can open and close, enabling digging and steel burying operations. The communication and power supply mechanism provides power for the operation of the device. The management system has functions such as parameter setting, data statistics and query, and personnel management. The management system can interact with the factory's production MES system. The communication and power supply mechanism provides power for the operation of the gantry crane and the grab bucket 10. Under the control of the control mechanism, the grab bucket 10 automatically buries the steel in the sand pit 11, realizing the process of slow cooling of steel by burying it in sand, improving production efficiency and reducing the labor intensity of workers.

[0032] Furthermore, the image acquisition mechanism has an intelligent camera and a vision workstation. The intelligent camera acquires images of the sand pit 11 in real time. Through the image processing software and recognition algorithm of the vision workstation, the coordinates of the steel placement position are accurately located, and the position data of the steel is transmitted to the control mechanism to control the grab bucket 10 to bury the steel.

[0033] Furthermore, the device also includes a detection and positioning mechanism. The detection and positioning mechanism adopts dual absolute encoders for redundant positioning. The detection and positioning mechanism uses a servo encoder to locate and detect the position of the grab bucket 10, reads the position information of the grab bucket 10 in real time, and guides the grab bucket 10 to complete the sand-turning and steel-burying operation to ensure that the steel can be completely buried.

[0034] Furthermore, all motion axes of the device are equipped with electrical soft limits and mechanical hard limits, and the status indicator lights of the trolley track system, trolley track system, and lifting mechanism automatically display the corresponding status during operation. The device also includes a safety protection system, in which a safety zone is demarcated around the sand pit 11. The safety protection system is interlocked with the safety zone and can detect personnel within the safety zone. When the safety protection system detects personnel entering the safety zone, the device automatically stops working. After the personnel leave the safety zone and confirm the safety reset on the operating table, the device starts working again. By demarcating a safety zone around the sand pit 11, the safety of the operation is improved.

[0035] The method of burying steel using the above-mentioned truss-type automatic sand-turning steel-burying device, such as... Figure 4 As shown, it includes the following steps:

[0036] Step 1, Preparation:

[0037] The control unit (industrial control computer) receives steel slow cooling process data from the factory's MES (Manufacturing Execution System). This data includes information such as the slow cooling time, steel type, and furnace card number. After receiving the data, the control unit manually confirms that the sand pit 11 area is safe and the equipment is in normal condition. If the operating conditions are not met, the device can only be started after they are fully met. If the sand pit 11 area is safe and the equipment is in normal condition, the start button is pressed on the control panel to start the device.

[0038] Step 2, dig a hole

[0039] After the device is started, the image acquisition mechanism scans the sand pit 11, identifies the unburied steel area in the sand pit 11, and generates digging coordinates which are transmitted to the control mechanism. The control mechanism moves the gantry crane above the unburied steel area and controls the gantry crane to drive the grab bucket 10 to perform the digging operation. After the grab bucket 10 completes the digging, it returns to the standby position. The digging operation can also be carried out before the work plan, thereby improving overall efficiency.

[0040] Step 3, hoisting and burying the steel

[0041] The overhead crane hoists the steel that needs to be cooled slowly into the dug sand pit 11. The control mechanism moves the truss crane above the steel in the sand pit 11. The control mechanism controls the truss crane to drive the grab bucket 10 to perform the steel burying operation. The detection and positioning mechanism monitors the attitude of the grab bucket 10 in real time to ensure complete burial.

[0042] Before burying the steel, the grab bucket 10 scans the sand pit 11 using an image acquisition mechanism to confirm the deviation between the actual position of the steel and the preset coordinates, dynamically correcting the burying path of the grab bucket 10 to achieve precise burying. During burying, the control mechanism directs the grab bucket 10 to dig sand in areas without steel to bury the steel. During the burying process, the image acquisition mechanism scans the sand pit 11 in real time and determines whether the steel is properly buried. If the steel is not completely buried, the grab bucket 10 continues to dig sand to bury the unburied areas until the steel is completely buried. After burying the steel, the image acquisition mechanism feeds the data back to the control mechanism, which records the slow cooling time according to process requirements.

[0043] Step 4: Slow cooling completed and steel tapping.

[0044] After slow cooling is completed, the overhead crane lifts the steel out of the sand pit 11; the image acquisition mechanism scans the location where the steel was removed, marks the area as a steel-free area, and records it as the area without steel to be buried in the next round, in preparation for the next steel burial.

[0045] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0046] A truss-type automatic sand-burying steel device automatically buries steel, achieving a slow cooling process by burying steel in sand, thus improving production efficiency and reducing the labor intensity of workers. Safety is enhanced by defining a safety zone around the sand pit 11. Compared with in-furnace slow cooling, it reduces gas consumption, achieving energy conservation and emission reduction.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
