[0035] Preferably, the side walls of adjacent connecting frames 36 are fixedly connected with a fall-prevention safety net 6, and the fall-prevention safety net 6 is a net-like structure made of nylon.

[0036] The working principle and beneficial effects of the above technical solution are as follows:

[0037] By setting the telescopic mechanism 5, it can be adjusted according to the width of the transport vehicle 2 to be applicable to different specifications of transport vehicles 2 for operation within the set safety net for transport vehicle operators. The telescopic mechanism 5 is provided with a first support plate 14. The first support plate 14 is fixedly installed at the bottom of the installation bracket 13, and the top of the first support plate 14 is fixedly connected with the inner wall of the installation bracket 13 through a fixed block 15. A first chute 18 is embedded on the first support plate 14. Two sets of telescopic components are connected to the first support plate 14 through a connecting plate 16.

The fixed end of the electric telescopic rod 20 is fixedly installed on the inner wall of the bottom of the installation bracket 13, and the telescopic end of the electric telescopic rod 20 is fixedly connected with the second support plate 17. By setting two sets of telescopic components to connect the first support plate 14 and the second support plate 17 through the connecting plate 16, and under the action of the electric telescopic rod 20, the telescopic mechanism 5 drives the installed fall-prevention safety net 6 to be unfolded, and at the same time, it can provide all-round protection along the circumferential side (excluding the front part) of the transport vehicle 2.

[0038] Secondly, the telescopic assembly connected to the first support plate 14 includes: one ends of a first connecting rod 21 and a second connecting rod 22 are hinged to the side wall of the first support plate 14, and the other ends of the first connecting rod 21 and the second connecting rod 22 are hinged with a third connecting rod 23 and a fourth connecting rod 24. One ends of the third connecting rod 23 and the fourth connecting rod 24 are hinged to both ends of the connecting plate 16. One end of a fifth connecting rod 25 is slidably connected in the first chute 18, and the other end of the fifth connecting rod 25 is hinged to the hinge joint of the second connecting rod 22 and the fourth connecting rod 24. The middle of the fifth connecting rod 25 is hinged to the first connecting rod 21. One end of a sixth connecting rod 26 is slidably connected in the second chute 19, and the other end of the sixth connecting rod 26 is hinged to the hinge joint of the first connecting rod 21 and the third connecting rod 23. The middle of the sixth connecting rod 26 is hinged to the fourth connecting rod 24. When the electric telescopic rod 20 expands and contracts, it drives the second support plate 17 to move, so that the mounting assemblies 27 on both sides of the connecting plate 16 expand and contract. Among them, the first connecting rod 21 and the second connecting rod 22 expand and contract under the action of the fifth connecting rod 25, and the fifth connecting rod 25 slides up and down along the first chute 18. At the same time, the third connecting rod 23 and the fourth connecting rod 24 expand and contract under the action of the sixth connecting rod 26, and the sixth connecting rod 26 slides up and down along the second chute 19. At the same time, the telescopic assemblies arranged on both sides of the connecting plate 16 act together, so as to realize the horizontal expansion and contraction of the entire telescopic mechanism 5, and enable the entire anti-falling safety net 6 to be spread out according to the actual situation of the transport vehicle 2.

[0039] For the two mounting assemblies 27 arranged as above, the two mounting assemblies 27 are respectively mounted on the tops of the fixed blocks 15 and the second support plate 17. The mounting assembly 27 is provided with two fixed sleeves 28. A housing 29 is fixedly installed on the tops of the fixed sleeves 28.

The inner side wall of the connecting frame 36 is slidably connected to the outer side wall of the housing 29; when the anti-falling safety net 6 connected to the mounting assembly 27 is being spread out or an operator falls, at this time the anti-falling safety net 6 will pull the connecting frame 36 to slide down along the housing 29, and the connecting frame 36 drives the connecting rod 34 to move down along the chute three 30 under the action of the fixed rod 35. At this time, the connecting rod 34 is connected to the sliding rod 31 through the hinge rod 33, and the sliding rod 31 realizes buffering in the fixed sleeve 28 under the action of the spring one 32. The side walls of adjacent connecting frames 36 are fixedly connected with the anti-falling safety net 6, and the anti-falling safety net 6 is a net-shaped structure made of nylon material, effectively ensuring the life safety of the operator.

Moreover, the anti-falling protective net 6 can be adjusted according to the width of the carriage through the telescopic mechanism 5. The anti-falling protective net 6 set in the present invention ensures that personnel will not fall under the vehicle after falling, thus playing a protective role and effectively guaranteeing the life safety of the operators.

[0041] Embodiment 3

[0042] On the basis of Embodiment 1 or 2, as Figure 1 、 Figures 4 - 5 shown, it further includes several auxiliary protection mechanisms 37. Several of the auxiliary protection mechanisms 37 are correspondingly arranged between two adjacent support columns 1. The auxiliary protection mechanism 37 is provided with two protection components. The protection component includes: a second mounting plate 38, the second mounting plate 38 is fixedly installed on the side wall of the support column 1. One side of a placing plate 39 is fixedly connected with a clamping sleeve 40. The bottom of a limiting sleeve 41 is fixedly installed on the top of the placing plate 39, and the placing plate 39 is arranged on the top of the second mounting plate 38. A mounting block 42 is fixedly installed on the top of the placing plate 39. The lower end of a support rod 43 is hinged to the mounting block 42. A pressing rod 44 is hinged to the upper end of the support rod 43, and one end of the pressing rod 44 passes through the side wall of the limiting sleeve 41 and is fixedly connected with the top of the placing plate 39 through a second spring 45. The bottom of a pressing block 46 slides through the top of the limiting sleeve 41 and contacts the pressing rod 44. A clamping block 47 is slidably connected in the clamping sleeve 40. The lower end of the clamping block 47 is clamped with a groove 48 on the top of the second mounting plate 38, and the top of the clamping block 47 is hinged to the other end of the pressing rod 44.

[0043] The working principle and beneficial effects of the above technical solution are as follows:

[0044] By installing several auxiliary protection mechanisms 37 on several support columns 1 where the protective net is installed, and several of the auxiliary protection mechanisms 37 are correspondingly arranged between two adjacent support columns 1, when the operator operates under the protection of the protective net of the transportation vehicle 2, it can give safety warnings to the personnel passing through the surrounding area of the protective net. Moreover, the auxiliary protection mechanism 37 can be flexibly installed and disassembled, and can be installed immediately when in use, effectively guaranteeing the safety during the operation of the protective net for the operators of the transportation vehicle 2.

[0045] Secondly, when the auxiliary protection mechanism 37 works, only the top of the placement plate 39 needs to be in contact connection with the top of the second mounting plate 38. The bottom of the pressing block 46 slides through the top of the limiting sleeve 41 and contacts the pressing rod 44. Then, press the pressing block 46 to slide downward along the limiting sleeve 41, so that the spring two 45 connected to the pressing rod 44 driven by the pressing block 46 is compressed. The mounting block 42 is fixedly installed on the top of the placement plate 39. The lower end of the support rod 43 is hinged to the mounting block 42, and the pressing rod 44 is hinged to the upper end of the support rod 43. Under the action of the support rod 43, the clamping block 47 hinged to one end of the pressing rod 44 slides upward along the clamping sleeve 40. At this time, the clamping block 47 enters the clamping sleeve 40, which is convenient for the lower end of the clamping block 47 to align with the groove 48 on the top of the second mounting plate 38 for clamping. After the clamping block 47 and the groove 48 are aligned with the left and right movement of the placement plate 39, then release the pressing block 46. At this time, the elastic force of the spring two 45 makes the pressing rod 44 drive the clamping block 47 to move downward along the clamping sleeve 40 under the action of the support rod 43. At this time, the clamping block 47 is in full contact with the groove 48 on the top of the second mounting plate 38 to complete the clamping, thus realizing the installation of the entire auxiliary protection mechanism 37; press the pressing block 46 again, so that the clamping block 47 is separated from the groove 48, then the rapid disassembly of the auxiliary protection mechanism 37 and the second mounting plate 38 is realized. The warning belt 49 connected to the protection component can prevent non-operators from being in danger when passing through the operation site, and can effectively ensure the safety of the operator's protective net operation of the entire transport vehicle 2.
