[0041] Optionally, at least some of the multiple first connecting column segments 3410 are rotatably arranged around their axes; at least some of the multiple second connecting column segments 3510 are rotatably arranged around their axes. In this way, through the rolling arrangement of the first connecting column segments and the second connecting column segments, the friction force generated by the chain 22 during the movement is further reduced, so that the movement of the chain is reliable.

[0042] Specifically, the transport device includes a plurality of first mounting structures, which are arranged one-to-one with the plurality of first connecting column sections 3410 ; the transport device includes a plurality of second mounting structures, which are arranged one-to-one with the plurality of second connecting column sections 3510 .

[0043] Specifically, multiple first mounting structures and multiple second mounting structures each include: two relatively arranged mounting seats and a rotating shaft, wherein the two ends of the rotating shaft are respectively connected to the two mounting seats, and the first connecting column segment or the second connecting column segment is rotatably mounted on the rotating shaft; wherein the extension direction of the rotating shaft is the same as the extension direction of the corresponding first connecting column segment or the second connecting column segment.

[0044] Optionally, the first connection column 341 is connected to the first receiving component 30 by welding, and the second connection column 351 is connected to the first receiving component 30 by welding.

[0045] Optionally, multiple first connecting column segments 3410 are formed by bending a round steel; multiple second connecting column segments 3510 are formed by bending a round steel, so that the connection between the multiple first connecting column segments 3410 and the connection between the multiple second connecting column segments 3510 are continuous, and the corners of the first connecting opening and the corners of the second connecting opening also have curved surfaces, thereby increasing the anti-friction range and further reducing the friction generated by the chain during movement.

[0046] The two mounting seats and the first receiving component 30 are an integrated structure; optionally, the two mounting seats and the first receiving component 30 are welded into an integrated structure; or, the two mounting seats and the first receiving component 30 are cast into an integrated structure.

[0047] Specifically, the first storage component 30 includes: an escape opening 303, which is arranged on the circumferential side wall of the first storage component 30, and the escape opening 303 is connected to the storage space 300, so that the chain 22 can selectively pass through the escape opening 303 or enter the storage space 300 from the escape opening 303.

In this way, in the process of the towing component 20 towing the hydraulic support 2, first, the shovel mounting structure 12 is rotated to the position where the shovel component 11 contacts the supporting base surface. When the towing component 20 drags the hydraulic support onto the shovel component 11 and drags it into place, the shovel mounting structure 12 drives the shovel component 11 to be transmitted to a transport position separated from the supporting base surface, so as to facilitate the transport of the hydraulic support by the transport vehicle.

[0052] Optionally, the shovel plate mounting structure 12 has a through hole 120 , which is arranged opposite to the storage space 300 . When the towing component 20 needs to tow the hydraulic support, the chain 22 passes through the storage space 300 and the through hole 120 in sequence.

[0053] Specifically, the first receiving member 30 includes a mounting plate 36 , which is disposed at the first communication opening 301 and extends along the circumferential direction of the first communication opening 301 .

[0054] Optionally, the mounting plate 36 is connected to the shovel plate mounting structure 12 ; or, the mounting plate 36 is connected to the transport vehicle body 1 .

[0056] In another embodiment of the present application, the mounting plate 36 is connected to the shovel plate mounting structure 12, and the shovel plate mounting structure 12 has a top plate, and an avoidance channel is provided on the top plate. The avoidance channel is connected to the avoidance opening so that the towing component 20 can escape from the avoidance channel and the avoidance opening together.

[0057] like Figure 3 As shown, when the dragging component 20 needs to be dragged at a large angle, the dragging component 20 is removed from the first storage component, thereby improving the working flexibility of the dragging component 20.

[0058] The utility model also provides a support transport vehicle, comprising: the above-mentioned transport device; and a transport vehicle body 1 , on which the transport device is mounted.

[0059] Specifically, during the operation of the support transporter, the hook 21 of the towing component 20 is used to connect with the hydraulic support 2 .

Through the above-mentioned arrangement, after the use of the towing component 20 is completed, the hook head 21 can be placed in the storage space 300 of the first storage component for storage. The first storage component can protect the hook head 21 and prevent it from falling on the ground. It can also prevent the hook head 21 from colliding with other components, thereby preventing the hook head 21 from being damaged. In this way, the service life of the hook head is improved.
