The pair of hydraulic support legs 682 are respectively arranged on the pair of connecting brackets 681. When the folding arm crane 68 is running, the execution ends of the pair of hydraulic support legs 682 extend downward and abut against the ground, which are used to support the folding arm crane 68 and assist the folding arm crane 68 to remain stable during operation.

[0084] When the user controls the device to lift the load-bearing device 3 and assembles it onto the transport vehicle 1, first, the second hydraulic telescopic rod 652 of the hydraulic drive assembly 65 of the pair of lifting modules 6 is extended, driving the boom 64 to flip a certain angle toward the rear of the transport vehicle 1 with the first adapter shaft 62 as the rotating shaft. During this process, the user drives the transport vehicle 1 to move in coordination with the boom 64 until the lifting handle 61 fixed on the load-bearing device 3 is inserted into the inner cavity of the hook 643 provided on the boom 64. After the lifting handle 61 is inserted into the inner cavity of the hook 643, the second hydraulic telescopic rod 652 of the pair of hydraulic drive assemblies 65 is contracted, thereby driving the boom 64 to flip back and return to the folded state. During the process of the boom 64 flipping back to the folded state, the boom 64 lifts the load-bearing device 3 through the hook 643 and the lifting handle 61. The lifting arm 64 is lifted up and drags the load-bearing device 3 onto the body of the transport vehicle 1, so that the bottom of the load-bearing device 3 abuts against the top of the pair of load-bearing beams 2, and the pair of assembly beams 4 are located between the pair of load-bearing beams 2, and the load-bearing section 641 of the lifting arm 64 is located between the pair of assembly beams 4; after the load-bearing device 3 is completely dragged to the top of the pair of load-bearing beams 2, the execution ends of the first hydraulic telescopic rods 51 of the pair of locking modules 5 extend through the assembly holes until the execution ends of the first hydraulic telescopic rods 51 are inserted into the inner cavity of the assembly beams 4 to prevent the load-bearing device 3 from moving up and down when bumps occur during transportation; in the process of the lifting arm 64 dragging the load-bearing device 3 to the top of the pair of load-bearing beams 2, the assembly beam 4 arranged at the bottom of the load-bearing device 3 passes through the upper surface of the protective plate 74, and in this process, a pair of limiting members 73 radially limit the load-bearing device 3.

[0085] After the load-bearing device 3 is completely dragged to the top of the pair of load-bearing beams 2 by the boom 64, the boom 64 is in a folded state, and the load-bearing section 641 of the boom 64 is between the load-bearing device 3 and the locking cross bar 66. The driving devices of the pair of locking assemblies 67 drive the hook 671 to deflect a certain angle, so that the head end of the hook 671 is stuck in the locking cross bar 66 to lock the boom 64. During the rotation of the hook 671, the tail end of the hook 671 drives the first connecting member 6721 to move accordingly, so that the guide column 6726 slides in the inner cavity of the guide hole 6723, and the distance between the guide column 6726 and the load-bearing column 6729 is gradually increased. The force of the reset spring 6730 gradually increases, and the reset spring 6730 is stretched; when the locking assembly 67 releases the lock on the suspension arm 64, the driving device releases the hook 671, and the reset spring 6730 recovers its deformation, pulling the guide column 6726 to slide along the guide hole 6723, and the distance between the guide column 6726 and the support column 6729 bracket gradually decreases. The guide column 6726 drives the first connecting member 6721 to move synchronously, so that the first connecting member 6721 pulls the hook 671 to deflect in the opposite direction by a certain angle, thereby releasing the clamping relationship between the head end of the hook 671 and the locking cross bar 66, and finally achieving the purpose of releasing the lock on the suspension arm 64.

[0086] Above, refer to Figures 1 to 10 The invention discloses a folding arm type vehicle-mounted crane transport vehicle, which has the following beneficial effects:

[0087] 1. The device realizes the detachable assembly of the carrying device and the transport vehicle through the locking module, so that in the process of loading a large number of small and light goods, the carrying device is first put down, and after the goods are loaded into the carrying device, the carrying device is reassembled on the transport vehicle, so as to enhance the convenience of use of the device and solve the defect of poor convenience of use in the prior art.

[0088] 2. After the load-bearing device is assembled on the transport vehicle, the load-bearing section of the boom is stored at the lower side of the load-bearing device to avoid limiting the height of the goods placed inside the load-bearing device, thereby enhancing the practicality of the device.
