Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , a refractory brick stacking device for a tunnel kiln car in this embodiment, includes a robotic arm body 1. A mounting frame 2 is fixedly installed at the output end of the robotic arm body 1. A cross plate 3 is detachably installed at the bottom of the mounting frame 2. A plurality of clamping jaws 4 are movably installed at both the front and rear ends of the bottom of the cross plate 3. A clamping mechanism 5 and a driving mechanism 6 are arranged on the cross plate 3.

[0020] In this embodiment, fixing screws 31 are movably installed around the top of the mounting frame 2. One end of each fixing screw 31 penetrates through the mounting frame 2 and is fixedly connected to the cross plate 3. Fixing nuts 32 are threadedly connected to the outer peripheral wall of the fixing screws 31 both above and below the mounting frame 2.

[0021] Specifically, the assembly of the clamping mechanism 5 can be conveniently and quickly completed by setting the fixing screws 31 and the fixing nuts 32.

[0022] In this embodiment, the clamping mechanism 5 includes sliding rails 51, sliders 52, L-shaped mounting frames 53 and cylinders 54. Sliding rails 51 are fixedly installed at both the front and rear ends of the bottom of the cross plate 3. A plurality of sliders 52 are slidably installed on the sliding rails 51. An L-shaped mounting frame 53 is fixedly installed at the bottom of each slider 52. Cylinders 54 are embedded on the opposite sides of the front L-shaped mounting frame 53 and the rear L-shaped mounting frame 53. The output end of the cylinder 54 is fixedly connected to the clamping jaw 4.

[0023] Specifically, by operating the cylinders 54 on both sides to drive the clamping jaws 4 to move relatively, the clamping operation of refractory bricks can be carried out.

[0024] In this embodiment, a positioning plate is fixedly installed at the center of the inner top wall of the L-shaped mounting frame 53. A positioning groove is formed at the top of the clamping jaw 4. The positioning groove matches the positioning plate.

[0025] Specifically, the moving direction of the clamping jaw 4 can be limited by setting the positioning groove and the positioning plate, so that it can move horizontally.

[0026] In this embodiment, the driving mechanism 6 includes a groove 61, a threaded slider 62, a driving motor 63, a double-axis screw 64 and a fixing plate 65. A groove 61 is provided at the center of the bottom of the cross plate 3. Threaded sliders 62 are slidably installed at both the left and right ends inside the groove 61. A driving motor 63 is fixedly installed on the left side of the cross plate 3. The output end of the driving motor 63 penetrates through the cross plate 3 and extends into the groove 61. A double-axis screw 64 is fixedly installed at the output end of the driving motor 63. One end of the double-axis screw 64 penetrates through the threaded slider 62 and is rotatably connected to the right inner wall of the groove 61. The double-axis screw 64 is composed of two threaded rods with opposite thread directions. The double-axis screw 64 is threadedly connected to the threaded slider 62. A fixing plate 65 is fixedly installed at the bottom of the threaded slider 62. One end of the fixing plate 65 is fixedly connected to the slider 52.

[0027] Connecting rods 521 are rotatably installed on the sides of adjacent sliders 52, and the opposite sides of adjacent connecting rods 521 are rotatably connected.

[0028] Specifically, turning on the driving motor 63 can drive the double-axis screw 64 to rotate. The double-axis screw 64 drives the threaded sliders 62 on both sides to move relatively. The threaded sliders 62 drive the fixing plate 65 to drive the sliders 52 at both ends to move away from each other. When the sliders 52 at both ends move away from each other, they pull the adjacent sliders 52 to move through the connecting rods 521. In this way, the clamped refractory bricks can be separated by the movement of the sliders 52, realizing the separated stacking of refractory bricks.
