Referring to fig. 1 to 4, the crash cushion turning device according to the embodiment of the present application includes a cushion support 2, a turning mechanism 3, a link mechanism one 4, a link mechanism two 5, a turning cylinder one 6, a turning cylinder two 7, a limiting mechanism 8, and a rear lower protection device 9, and a crash cushion support 101 for supporting a head portion (see fig. 1) of the crash cushion 1 in a folded state is provided on a frame 10 of the crash cushion vehicle.
The anti-collision buffer cushion 1 is fixed with a buffer cushion support 2, the buffer cushion support 2 is hinged with a first overturning oil cylinder 6 piston rod through a first pin shaft 21 (a first gasket, a first nut and a first split pin are arranged on the first overturning oil cylinder), the first overturning oil cylinder 6 cylinder end is hinged with a turnover mechanism 3 through a third pin shaft 31 (a third gasket, a third nut and a third split pin are arranged on the third overturning oil cylinder), the turnover mechanism 3 is hinged with the buffer cushion support 2 through a second pin shaft 25 (a second gasket, a second nut and a second split pin are arranged on the second overturning oil cylinder), the first connecting rod mechanism 4 is hinged with a second connecting rod mechanism 5 through a seventh pin shaft 55 (a seventh gasket, a seventh nut and a seventh split pin are arranged on the first connecting rod mechanism, the second connecting rod mechanism 5 is fixedly installed on an anti-collision buffer car frame 10, the second overturning oil cylinder 7 cylinder end is hinged with the first connecting rod mechanism 4 through a fourth pin shaft 41 (a fourth gasket, a fourth nut and a fourth split pin), and the piston rod end of the second overturning oil cylinder 7 is hinged with the second connecting rod mechanism 5 through a sixth pin 51. The second connecting rod mechanism 5 is matched with the first connecting rod mechanism 4 in a limiting way through a first limiting face 59 of the connecting rod mechanism, the first connecting rod mechanism 4 is supported when the crash cushion 1 rotates to the middle state and the unfolding state, the first connecting rod mechanism 4 is prevented from rotating by more than 90 degrees, a rear lower portion protection device 9 is installed on the turnover mechanism 3 and is used for protecting the rear lower portion of the crash cushion vehicle when the crash cushion 1 is in the folding state, a limiting mechanism 8 is installed on the turnover mechanism 3 and is used for limiting the supporting of the limiting face 29 of the cushion support on the cushion support 2 when the crash cushion 1 is in the unfolding state, a piston rod of the first turnover oil cylinder 6 draws the upper left portion of the crash cushion 1 through a first pin shaft 21, and the crash cushion 1 is ensured to face backwards.
The limiting mechanism 8 is provided with an adjusting bolt 81 and an adjusting nut 82, the adjusting bolt 81 is installed on the turnover mechanism 3 and meshed with the adjusting nut 82, and the cushion support limiting surface 29 is supported by the adjusting nut 82.
When the anti-collision buffer vehicle is in a running state, the first connecting rod mechanism 4 is locked with the second connecting rod mechanism 5 through the fifth pin shaft 45, the fifth gasket 46 and the fifth cotter pin 47, so that the phenomenon that the second turnover oil cylinder 7 is damaged by external force impact when rear-end collision occurs is avoided, and meanwhile, the phenomenon that the second turnover oil cylinder 7 is damaged due to the fact that the turnover mechanism 3 and the first connecting rod mechanism 4 shake inertia force under the running condition of a rugged road surface can be avoided.
The overturning device can realize the overturning action of the crash cushion 1, and the crash cushion 1 rotates clockwise from a vehicle running state (see a solid line part or a graph 2 in a graph 1, also called a furled state) to a middle transition state (see a dotted line upright part and a graph 3 in the graph 1) which is erected by 90 degrees, and then rotates clockwise by 90 degrees to a road maintenance operation, temporary road construction and traffic accident site treatment state (see a graph 4, also called an unfolded state) can be finished by controlling the telescopic stroke of the overturning oil cylinder. When the crash cushion 1 rotates from a furled state to a middle transition state, the second turnover oil cylinder 7 moves in a retracting direction, the first link mechanism 4 moves clockwise around the seventh pin shaft 55 as shown in fig. 1, the crash cushion 1 and the cushion support 2 move synchronously along with the first link mechanism 4 and the turnover mechanism 3 to realize the 90-degree unfolding action of the crash cushion 1, and the second link mechanism 5 is matched with the first link mechanism 4 for limiting through the first link mechanism limiting surface 59, and then the second link mechanism 5 and the first link mechanism 4 do not change in relative position relation when the crash cushion 1 continues to unfold, namely, only two stable states exist between the two link mechanisms, one is a state that the two link mechanisms form a 90-degree included angle as shown in fig. 2, the other is a state that the second link mechanism 5 shown in fig. 3 and 4 supports and blocks the first link mechanism 4 and the two link mechanisms are integrally parallel, and similarly, the turnover mechanism 3 only changes from the furled state to the middle transition state; when crash cushion 1 rotates to the expansion state from middle transition state, 6 piston rods of a turnover oil cylinder move towards the extending direction, crash cushion 1 and cushion support 2 continue to move around two 25 pin shafts according to the clockwise direction shown in figure 1, and then crash cushion 1 further expands to move, finally the range of crash cushion overturning by 180 degrees can be realized, and the movement of crash cushion 1 when expanding to the horizontal state is limited by a limiting mechanism 8.
After the road maintenance operation, the temporary road construction and the traffic accident site treatment work are completed, the collision-proof cushion pad 1 is required to be retracted to a driving state, and the operation can be completed by controlling the telescopic stroke of the turnover oil cylinder. Firstly, a piston rod of a first turning oil cylinder 6 acts in the retracting direction, the crash cushion 1 and the cushion bracket 2 are pulled by the first turning oil cylinder 6, and the cushion bracket 2 starts to move around a second pin shaft 25 in the anticlockwise direction shown in figure 1, so that the crash cushion 1 is retracted to be upright at 90 degrees; then the piston rod of the second turnover oil cylinder 7 extends out, the first connecting rod mechanism 4 moves anticlockwise as shown in figure 1 around the seventh pin shaft 55, and the crash cushion 1 and the cushion support 2 move synchronously with the first connecting rod mechanism 4 and the turnover mechanism 3 to realize the reset of the crash cushion 1.
The embodiment introduces the crash cushion overturning device of the crash cushion vehicle, and does not introduce other special devices of the crash cushion vehicle. The upset hydro-cylinder is flexible to be realized tilting mechanism, link mechanism motion, accomplishes crashproof blotter's upset action, and stop gear 8 realizes the angle control that crashproof blotter 1 expandes.
From the mechanical principle, the cushion support 2 and the turnover mechanism 3 form a revolute pair for converting between the intermediate transition state and the unfolding state in the embodiment, and the link mechanism I4 and the link mechanism II 5 form a revolute pair for converting between the intermediate transition state and the folding state, so that two revolute pairs are provided, and one to two revolute pairs are added on the basis of the prior art, so that the road surface operations such as road maintenance operation, temporary road construction, traffic accident field treatment and the like are more convenient and safer, and the function of the rotary joint is greatly improved compared with the original function.
