[0040] Embodiment 2:

[0041] The door frame and corridor of the optical fiber production workshop have a limited width of 600mm, a limited height of 1900mm, and a maximum length of 2400mm for the transported glass tube rod 6. Therefore, the width of the transfer trolley frame 2 is designed to be 300mm, and the transfer trolley frame 2 is tilted 45° to the ground during transportation, so that it can be easily transferred between various workshops with space restrictions. In order to prevent the long glass tube rod from pressing against the operator, the transfer trolley needs to be equipped with an extended handle 7.

[0042] In order to facilitate the operator to control the forward direction and prevent the transfer trolley from moving when loading and unloading the glass tube rod when parking, the front end of the transfer trolley is equipped with a directional roller 16 and the rear end is equipped with a universal wheel 13 with a brake. At the same time, in order to ensure that the universal wheel 13 rotates more smoothly during the transfer process, the universal wheel frame 10 near the universal wheel 13 is specially designed to be a bending structure 1001 perpendicular to the ground. When loading, just pull out the blocking insert 4 and put it into the blocking insert storage barrel 15, put the glass tube rod 6 into the bottom stopper 1 and the support block 3, then take out the blocking insert 4 from the blocking insert storage barrel 15 and insert it into the support block 3, and finally tighten the first locking screw 5 by hand to prevent the blocking insert 4 from loosening during the transfer process. The plug-in design of the blocking insert 4 and the support block 3 makes the entire operation simpler and more convenient. At the same time, the design of the blocking insert storage barrel 15 is also very user-friendly, which prevents the blocking insert from being lost due to human misplacement during multiple uses. In order to reduce the storage space, the transfer trolley can be folded when not in use.

[0043] The folding operation is as follows: loosen the second locking screw 501 by hand, pull out the sleeve 8 to the limit step 701 of the handle 7, and let the sleeve 8 completely detach from the handle connecting shaft 201 of the transfer trolley frame 2, so that the handle 7 will rotate vertically downward around the pin 9. Then, the universal wheel frame 10 is moved toward the transfer trolley frame 2, and the first connecting rod 11 and the second connecting rod 12 will be folded upward at a certain angle. Finally, the bottom plate of the transfer trolley frame 2 and the directional roller 16 are placed on the ground at the same time, and the entire transfer trolley is placed vertically.

[0044] The process of folding and unfolding the transfer trolley is the reverse process of the above folding operation. It is particularly noted that when the first connecting rod 11 and the second connecting rod 12 are extended downward, the circular baffle 1201 on the second connecting rod 12 will play a limiting role and force the first connecting rod 11 and the second connecting rod 12 to be in a straight line. The transfer trolley frame 2, the universal wheel frame 10 and the first connecting rod 11 and the second connecting rod 12 together form a stable triangle, so that the unfolded transfer trolley will be placed on the ground very stably.

[0045] Use a clamp to load the glass tube rods diagonally on the transfer cart. It is not advisable to load too many glass tube rods at the same time, for example, only 3-4 rods are needed, so the width of the transfer cart can be made relatively narrow, so that the transfer cart can be circulated in various workshops with height and width restrictions; in order to avoid the long glass tube rods pressing against the operator, the transfer cart needs to be equipped with an extended handle; in order to facilitate the operator to control the forward direction and prevent the transfer cart from moving when installing and removing glass tube rods when parking, the front end of the transfer cart is equipped with directional rollers and the rear end is equipped with universal wheels with brakes. In order to reduce storage space, the transfer cart can be folded when not in use.

[0046] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
