[0042] like Figures 1 to 4 As shown, this embodiment provides a crystal rod transport vehicle, which includes a vehicle body 100 and a first carrier 200. The vehicle body 100 has a supporting portion; the first carrier 200 has a first receiving groove 210, which extends along the length direction of the vehicle body 100. The first receiving groove 210 is used to receive crystal rods 1000 whose axes are arranged along the length direction of the vehicle body 100, that is, the axis of the first receiving groove 210 is parallel to the axis of the crystal rod 1000; along the axis direction of the crystal rod 1000, the length of the first receiving groove 210 is greater than or equal to the length of the crystal rod 1000; the first carrier 200 is made of a cushioning material, and the first carrier 200 is placed in the supporting portion, and the first carrier 200 is fixed to the vehicle body 100 in the horizontal direction. The horizontal direction refers to the length and width directions of the vehicle body 100.

[0043] The above configuration allows the crystal rod 1000 to be protected by the first carrier 200 during transportation. When encountering uneven road surfaces, it can buffer the crystal rod 1000 and prevent separation between the crystal rod 1000 and the first carrier 200. This avoids collisions or friction between the crystal rod 1000 and the first carrier 200, reduces the possibility of damage to the crystal rod 1000, and reduces the breakage rate of subsequent slicing.

[0044] To effectively support the crystal ingot 1000, considering that the cross-section of the crystal ingot 1000 is circular, in some embodiments, the cross-section of the first receiving groove 210 is arc-shaped or V-shaped. When the cross-section of the first receiving groove 210 is arc-shaped, its radius is equal to the radius of the crystal ingot 1000. In other embodiments, the cross-section of the first receiving groove 210 can also be square. In other embodiments, the first receiving groove 210 can also be provided with other shapes, as long as it can achieve the positional constraint of the crystal ingot 1000.

[0045] To facilitate the handling of the crystal ingot 1000 using mechanical equipment, in some embodiments, the depth of the first receiving groove 210 is less than the radius of the crystal ingot 1000. This arrangement makes it easier to grip or lift the portion of the crystal ingot 1000 outside the first receiving groove 210. Specifically, a human hand or mechanical gripper can easily grasp the crystal ingot 1000 from above, and the grasping point is located below a horizontal plane passing through the diameter of the crystal ingot 1000.

[0046] During transportation, to improve safety, the outer periphery of the crystal ingot 1000 needs to be protected. Therefore, guardrails are typically installed around the vehicle body 100. However, high guardrails can affect the convenience of loading and unloading the crystal ingot 1000. To solve this problem, in some embodiments, [the following is a separate, unrelated sentence:] Figure 3 As shown, the crystal rod transport vehicle also includes a protective component 400 and a locking component 500. The protective component 400 is hinged to both sides of the vehicle body 100 and can rotate between a vertically upward protective position and a vertically downward clearance position. The locking component 500 is used to lock the vehicle body 100 and the protective component 400 in the protective position. This configuration allows the protective component 400 to be rotated to the clearance position during loading and unloading, thereby placing the protective component 400 below the load-bearing part and avoiding any impact on the loading and unloading of the crystal rods 1000. Simultaneously, it reduces the lifting height of the crystal rods 1000, saving manpower.

[0047] In some embodiments, the vehicle body 100 has an elongated hole 110 extending vertically and a locking groove 120 located above the elongated hole 110 and with its opening facing away from the elongated hole 110. The protective member 400 is provided with a cylindrical pin 410, which is rotatably disposed in the elongated hole 110 and can slide within the elongated hole 110. The locking member 500 is a pin disposed on the protective member 400. When the protective member 400 is in the protective position, the pin is inserted into the locking groove 120. In use, by pulling the protective member 400 in the protective position upward, the pin can be removed from the locking groove 120. Then, by flipping the protective member 400 outward, the pin can be moved away from the locking groove 120. Finally, after the protective member 400 is flipped 180°, the cylindrical pin 410 abuts against the lower end of the elongated hole 110 and supports the protective member 400. The vehicle body 100 has two elongated holes 110, and the protective component 400 is provided with two cylindrical pins 410 arranged at intervals along the length of the vehicle body 100. The two cylindrical pins 410 are respectively slidably disposed in the two elongated holes 110.

[0048] In some embodiments, the first carrier 200 is made of pearl cotton. The density of pearl cotton ranges from 15 kg / m³. 3 ~30kg / m 3 Preferably, the density of the pearl cotton is 18 kg / m³. 3 .

[0049] When the length of the crystal ingot 1000 is short, especially less than 200mm, horizontal placement can easily lead to tilting. Therefore, in some embodiments, the crystal ingot transport vehicle further includes a second carrier 300. The second carrier 300 has a second receiving groove 310 with its axis extending vertically. The cross-section of the second receiving groove 310 is circular and is used to receive the crystal ingot 1000 arranged with its axis vertically. Vertical placement of the crystal ingot 1000 is more stable, avoiding the problem of the crystal ingot 1000 tilting during transport. It should be noted that the material of the second carrier 300 is the same as that of the first carrier 200.

[0050] To improve transfer efficiency, in some embodiments, combined with Figure 4 As shown, the second carrier 300 has two second receiving slots 310, which are spaced apart along the length of the vehicle body 100. The ingot 1000 transfer vehicle includes a plurality of second carriers 300, which are spaced apart along the width of the vehicle body 100. Specifically, the ingot 1000 transfer vehicle has two second carriers 300. In other embodiments, the ingot 1000 transfer vehicle has two first carriers 200.

[0051] Furthermore, the vehicle body 100 has a first support platform 101 and a second support platform 102, which are arranged vertically at intervals. The first carrier 200 is placed in the first support platform 101, and the second carrier 300 is placed in the second support platform 102. The first support platform 101 is located above the second support platform 102. This arrangement further increases the number of disposable transfer ingots 1000.

[0052] When removing the crystal ingot 1000 from the second carrier 300, it is generally necessary to start from the bottom to lift the crystal ingot 1000. To facilitate operation, the second carrier 300 also includes a support groove 320. The support groove 320 is partially located outside the second receiving groove 310 and partially located inside the second receiving groove 310. The bottom of the support groove 320 is lower than the bottom of the second receiving groove 310. Both the support groove 320 and the second receiving groove 310 have their openings facing upwards. The above configuration provides space for the operator to place their hands, improving the transfer efficiency and convenience of the crystal ingot 1000.

[0053] In some embodiments, the support groove 320 located outside the two second receiving grooves 310 extends outward through the second carrier 300. This arrangement makes the support groove 320 easier to manufacture and saves material on the second carrier 300. The second carrier 300 includes two second receiving grooves 310, and the two second receiving grooves 310 share a single support groove 320.

[0054] To facilitate transfer, in some embodiments, the bottom of the vehicle body 100 is provided with rollers 130. The rollers 130 are made of rubber to provide cushioning, further reducing the probability of collision and friction between the crystal rod 1000 and the first carrier 200. The supporting part is a mounting groove located on the upper side of the vehicle body 100. The first carrier 200 is placed in the mounting groove, and the first carrier 200 is generally cuboid in shape, with its four outer sidewalls abutting against the four sidewalls of the mounting groove.

[0055] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
