The second connecting base 220 has the same structure as the first connecting base 210. The connecting seat plates 211 of the second connecting base 220 and the first connecting base 210 are respectively provided with pin holes 214. The first connecting base 210 and the second connecting base 220 span the main beams on both sides of the slewing bracket or the corresponding mounting components. A pin passes through the pin hole 214 on the connecting plate 211 of the first connecting base 210, through the main beam of the slewing bracket or the mounting component, and then through the pin hole 214 on the connecting plate 211 of the second connecting base 220 to complete the pin connection. The first connecting base 210 and the second connecting base 220 are connected by two pins to form a double-pin structure.

[0038] Specifically, the working principle of the road surface removal drum support device is as follows: During use, the first connecting base 210 and the second connecting base 220 span the main beams on both sides of the rotary support. A pin passes through the pin hole 214 on the connecting plate 211 of the first connecting base 210, through the main beam of the rotary support, and then through the pin hole 214 on the connecting plate 211 of the second connecting base 220, completing the pin connection. The corresponding first connecting base 210 and second connecting base 220 form a double-pin structure through the two pin connections. The rotary support of the work vehicle drives the rectangular frame assembly 100 to rotate to a position perpendicular to the vehicle body. The hydraulic motor 330 drives the drive gear 340 to rotate. The drive gear 340 drives the gear ring 460 through gear meshing, which in turn drives the truss reel 410 to rotate. The bearing head 430 rotates within the bearing seat 350. The folded road surface is guided along the outer edges of the middle drum frame 420 and the side drum frames 440 for winding and removal. The upper center of the truss roll 420 has a groove to accommodate the traction belt connecting the road surface section. The traction pulls the folded road surface onto the central roll 420 for winding. The limiting frame 450, located at both ends of the truss roll 410, acts as a lateral limit during the road surface section retraction and release operations. The rotation of the truss roll 410 winds the folded road surface from the lower sides of the central roll 420 and side roll 440 onto the truss roll assembly 400 to form a road surface roll. During this process, the surface of the folded road surface... The guide wheel 140 on the road surface guides the winding and retraction of the truss drum assembly 400. The two ends of the folded road surface are guided by the road surface end limiting wheel 150, so that the folded road surface is neatly stored on the truss drum assembly 400. After the truss drum 410 is fully loaded with the road surface, the double pins on the connecting base assembly 200 are released, so that the lifting ring 370 of the road surface retraction drum support device can be lifted off, so as to replace the new road surface retraction drum support device and continue to retract the folded road surface.

[0039] It should be noted that the specific model and specifications of the hydraulic motor 330 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0040] The fluid supply and operating principle of the hydraulic motor 330 are clear to those skilled in the art and will not be described in detail here.

[0041] The above are merely embodiments of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations.
