When disassembling the silicon rod, after rotating the worm 9, the worm wheels 8 on both sides thereof can be driven to rotate, and the kinetic energy is transmitted to the gear 6 through the belt 7, and finally the screw 5 is driven to rotate, so that the top block 3 can be longitudinally moved along the thread direction of the screw 5, and as the top block 3 moves upward, the top block 3 can be pushed under the silicon rod until it is lifted up, and lifting the silicon rod can facilitate workers to perform operations such as hoisting on it, and can also avoid slippage when loading and unloading the silicon rod;

[0025] Furthermore, the roller 4 can prevent the silicon rod from slipping in the axial direction, and can also reduce the friction between the top block 3 and the silicon rod when the top block 3 pushes against the lower end of the silicon rod.

[0026] Furthermore, the worm 9 can be driven by a motor, which can reduce the workload of workers.

[0027] like Figure 4-Figure 5As shown, two screw rods 5 are symmetrically arranged along the center line of the mounting column 2, a gear 6 is fixedly arranged at the lower end of the screw rod 5, and a belt 7 is arranged on the outer side of the gear 6, a worm wheel 8 is arranged on one side of the gear 6, and the lower end of the worm wheel 8 is rotatably connected to the base 1, the worm wheel 8 and the gear 6 are connected through the belt 7, one side of the worm wheel 8 is located in the middle of the base 1 and meshed with a worm 9, one end of the worm 9 penetrates one side of the base 1, the middle part of the base 1 is located between the mounting columns 2 and a sleeper 10 is slidably arranged, and two sleepers 10 are arranged, and a damping rod 11 is fixedly arranged at the lower end of the sleeper 10, and the damping rod 11 Two groups are symmetrically arranged along the center line of the sleeper 10, two in each group, the lower end of the sleeper 10 is slidably provided with a slide rail 12 between the damping rods 11, and both ends of the slide rail 12 are fixedly connected to the base 1, a total of four slide rails 12 are arranged, two in each group, and a circular groove 13 is opened on the opposite side of the slide rail 12, one side of the circular groove 13 is located inside the sleeper 10 and a spring 14 is fixedly arranged, and two springs 14 are symmetrically arranged along the center line of the sleeper 10, and a limit block 15 is fixedly arranged at the other end of the spring 14, and the limit block 15 is slidably connected to the sleeper 10 and the slide rail 12 at the same time, the base 1 A mounting frame 16 is fixedly provided on both sides of the mounting frame 16, and a guard plate 17 is slidably provided inside the mounting frame 16. Slots 18 are provided on both sides of the guard plate 17, and four slots 18 are symmetrically provided along the center line of the guard plate 17. A latch 19 is slidably provided inside the slot 18, and two latches 19 are symmetrically provided along the center line of the guard plate 17.

When the equipment encounters an emergency situation and an emergency stop occurs When the sleeper 10 moves, the damping rod 11 can first offset part of the impact force to prevent the silicon rod from being excessively deflected due to inertia, and when the sleeper 10 is in position, the limit block 15 at its lower end can enter the circular groove 13 under the action of the spring 14 until the sleeper 10 stops moving, thereby preventing the sleeper 10 from being excessively deflected and causing excessive wear on the silicon rod; before moving the silicon rod, the pull rod 20 can be used to pull the pin 19 out of the slot 18, so that the guard plate 17 can be pulled out upward until the pin 19 enters the slot 18 at the lower end, so that the guard plate 17 can be used to protect both sides of the silicon rod.

[0028] Furthermore, the cooperation between the circular groove 13 and the limiting block 15 can have a braking effect on the sleeper 10, and the impact force can be further offset by the limiting block 15 repeatedly entering the circular groove 13 when the sleeper 10 moves.

[0029] Working principle: When using the electric loading vehicle with a double-sided protection structure, first, when disassembling the silicon rod, after rotating the worm 9, the worm wheels 8 on both sides can be driven to rotate, and the kinetic energy is transmitted to the gear 6 through the belt 7, and finally the screw 5 is driven to rotate, so that the top block 3 can be moved longitudinally along the thread direction of the screw 5. As the top block 3 moves upward, the top block 3 can be pushed under the silicon rod until it is lifted up. Lifting the silicon rod can facilitate workers to perform operations such as hoisting on it, and can also avoid slippage when loading and unloading the silicon rod; secondly, when the equipment encounters an emergency stop due to an emergency, the damping is first used. The rod 11 can offset part of the impact force to prevent the silicon rod from being excessively deflected due to inertia, and when the sleeper 10 is displaced, the limit block 15 at the lower end can enter the circular groove 13 under the action of the spring 14 until the sleeper 10 stops moving, which can prevent the sleeper 10 from being excessively deflected, thereby causing excessive wear on the silicon rod; finally, before the silicon rod is moved, the pin 19 can be pulled out of the slot 18 by the pull rod 20, so that the guard plate 17 can be pulled out upwards until the pin 19 enters the slot 18 at the lower end, so that the two sides of the silicon rod can be protected by the guard plate 17. This is the working principle of the electric charging vehicle with a bilateral protection structure.
