[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 3 It is known that a robotic dog for inspecting the casting process includes a chassis 1, multiple casters 2 at the bottom of the chassis 1, liftable drive wheels 3 at the bottom of the chassis 1, a control box 4 on the top of the chassis 1, a CCD camera 5 on the top of the control box 4, a fixing plate 6 extending from the side of the control box 4, and a temperature probe 7 retractably installed below the fixing plate 6.

[0019] In practical use, this utility model

[0020] Place this robot dog in the foundry workshop, start the equipment, and perform inspection tasks according to the preset program. The CCD camera 5 can take pictures of the casting liquid on the casting tray to determine if there is a lack of liquid. The temperature probe 7 can detect the temperature of the casting liquid and determine whether the temperature of the casting liquid meets the standard.

[0021] Robotic dogs have replaced manual inspections, avoiding human contact with high-temperature casting liquid and eliminating safety hazards.

[0022] The control box 4 has a telescopic sleeve 8 inside, and a first motor 9 is fixed inside the sleeve 8. The first motor 9 is connected to the drive wheel 3. The control box 4 has a first hydraulic cylinder 10 inside, and the telescopic rod of the first hydraulic cylinder 10 is sleeved with the sleeve 8. A gear ring 11 is provided on the outside of the sleeve 8. The control box 4 has a second motor 12 inside, and a gear 13 that meshes with the gear ring 11 is fixed on the output shaft of the second motor 12. When the sleeve 8 is raised and lowered, the gear ring 11 and the gear 13 maintain meshing and transmission.

[0023] The first hydraulic cylinder 10 controls the lifting and lowering of the sleeve 8 and the drive wheel 3, so that the drive wheel 3 contacts the ground. After the drive wheel 3 contacts the ground, the first motor 9 controls the rotation of the drive wheel 3 to make the robot dog move. The second motor 12 controls the rotation of the sleeve 8, so as to make the drive wheel 3 turn relative to the chassis 1, thereby changing the direction of the robot dog's movement.

[0024] A top block 14 is telescopically mounted on the top of the sleeve 8. A spring 15 is provided between the top block 14 and the sleeve 8. A transmission shaft 16 is provided between the top block 14 and the first motor 9, and the top block 14 and the transmission shaft 16 are slidably connected. The first motor 9 can drive the top block 14 to rotate. The top of the top block 14 has a conical structure. A connecting block 17 is provided on the top of the control box 4. A groove 18 that mates with the top block 14 is provided in the connecting block 17. The contact surfaces of the top block 14 and the groove 18 are in frictional engagement. A gimbal 19 that is fixedly connected to the connecting block 17 is provided on the outside of the control box 4. The CCD camera 5 is fixed on the gimbal 19 and the CCD camera 5 is tilted downward.

[0025] When the first hydraulic cylinder 10 pushes the sleeve 8 upward, the top block 14 engages with the groove 18 of the connecting block 17, and a frictional engagement is formed between the contact surfaces. The top block 14 can drive the connecting block 17 to rotate, thereby driving the gimbal 19 to rotate, so that the CCD camera 5 can capture images from multiple directions.

[0026] When the top block 14 and the connecting block 17 are engaged, the spring 15 pushes the top block 14 so that it is close to the connecting block 17 and the sleeve 8, thus playing a buffering role and avoiding rigid impact between the top block 14 and the connecting block 17.

[0027] When the CCD camera 5 is oriented, the first hydraulic cylinder 10 pushes the sleeve 8 upward, and the drive wheel 3 does not contact the ground. At this time, the CCD camera 5 rotates under the action of the first motor 9, which will not drive the robot dog itself to move, thus ensuring the stability of the shooting.

[0028] The CCD camera 5 is tilted downwards to facilitate capturing the distribution of casting liquid on the casting tray.

[0029] A second hydraulic cylinder 20 is fixed on the fixed plate 6. The second hydraulic cylinder 20 controls the lifting and lowering of the temperature probe 7 to adapt to the casting plate at different heights and detect the temperature of the casting liquid.

[0030] Compared with the prior art, this utility model has the following advantages: it can adapt to the replacement of manual inspection by robot dogs, avoid personnel from coming into contact with high-temperature casting liquid, and eliminate safety hazards.
