By setting the weighing platform 7, weighing can be performed, and a sensor 8 is detachably installed at the bottom of the weighing platform 7. By setting the sensor 8, the value can be transmitted. A box 11 is fixedly installed on the bottom outer wall of the connecting plate 10, and a mounting mechanism is arranged in the box 11; the sensor 8 can be quickly installed and disassembled by setting the mounting mechanism.

[0033] Among them, the installation mechanism includes a first rack plate 13 and a second rack plate 14, and the first rack plate 13 and the second rack plate 14 are respectively slidably installed on the inner walls on both sides of the box body 11. A gear 15 is rotatably installed on the inner wall of one side of the box body 11. By setting the gear 15, the first rack plate 13 and the second rack plate 14 can be driven to approach or move away from each other. A motor 16 is provided on the outer wall of one side of the box body 11, and the output end of the motor 16 passes through the outer wall of one side of the box body 11 and is fixedly connected to the gear 15.

[0034] When in use, by controlling the starting motor 16, the output end of the motor 16 will drive the gear 15 to rotate, and the rotation of the gear 15 will drive the first rack plate 13 and the second rack plate 14 to move away from each other, thereby simultaneously releasing the fixed installation of the two sensors 8, facilitating quick disassembly and installation, thereby improving work efficiency.

[0035] Reference Figure 1 and Figure 3Two mounting grooves 17 for mounting sensors 8 are symmetrically provided in the concrete floor 1, and the sensors 8 are located on the side where the scale platform 7 and the concrete floor 1 are close to each other. By providing the mounting grooves 17, the sensors 8 can be assisted in mounting.

[0036] Reference Figure 2 and Figure 4 The outer walls of the first rack plate 13 and the second rack plate 14 that are away from each other are respectively penetrated and slidably installed on the outer wall of the box body 11, and the outer walls of the first rack plate 13 and the second rack plate 14 that are away from each other are respectively abutted with the corresponding sensors 8. By providing the first rack plate 13 and the second rack plate 14, the two sensors 8 can be abutted, fixed and removed at the same time.

[0037] Reference Figure 3 and Figure 4 A support frame 12 is fixedly mounted on one side outer wall of the box body 11, and the motor 16 is fixedly mounted on the support frame 12. By providing the support frame 12, the motor 16 can be mounted on it, which plays a role of auxiliary installation.

[0038] Reference Figure 1 and Figure 2 The guide rail 3 and the weighing rail 4 are both installed and connected to the concrete floor 1 through the track anti-climbing device 5. Two through grooves 6 are symmetrically provided on the connecting plate 10, and the two weighing platforms 7 are respectively located in the two corresponding through grooves 6. The through grooves 6 are provided to facilitate the installation of the weighing platform 7.

[0039] Reference Figure 3 The box body 11 is fixedly connected to the connecting plate 10 by external bolts. The box body 11 is fixedly connected to the connecting plate 10 by external bolts, so that it is easy to install and disassemble.

[0040] Reference Figure 4 A fixing frame 18 is fixedly mounted on one side outer wall of the box body 11, a cylinder 19 is fixedly mounted on the fixing frame 18, a rectangular plate 20 is fixedly mounted on the output end of the cylinder 19, and a limiting column 21 is fixedly mounted on one side outer wall of the rectangular plate 20.

[0041] Reference Figure 4 One end of the limiting column 21 passes through the outer wall of one side of the box body 11 and is located on the latching teeth of the second rack plate 14. By setting one end of the limiting column 21 to pass through the outer wall of one side of the box body 11 and be located on the latching teeth of the second rack plate 14, the second rack plate 14 can be limited and fixed, preventing the second rack plate 14 from automatically moving when disassembled, thereby affecting the fixing effect.

[0042] The implementation principle of the present application is as follows: when in use, the molten iron tank car travels through the guide rail 3 and the weighing rail 4, and when the molten iron tank car travels on the guide rail 3 and the weighing rail 4, the downward pressing force is transmitted to the sensor 8 at the bottom of the weighing platform 7 through the connecting plate 10, so as to facilitate weighing;

[0043] When the sensor 8 needs to be disassembled and replaced, the output end of the cylinder 19 is controlled to start, and the rectangular plate 20 and the limit column 21 are driven to move. The movement of the limit column 21 can release the restriction on the second rack plate 14. At this time, the starting motor 16 can be controlled, and the output end of the motor 16 can drive the gear 15 to rotate. The rotation of the gear 15 will drive the first rack plate 13 and the second rack plate 14 to move away from each other, thereby releasing the fixed installation of the two sensors 8 at the same time, facilitating quick disassembly and installation, thereby improving work efficiency.
