Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example
[0025] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:
[0026] A folding arm crane center of gravity reinforcement device comprises: two first reinforcement blocks 1 and connecting hinges 2, the two connecting hinges 2 are used for rotationally connecting the two first reinforcement blocks 1, the surface of the first reinforcement block 1 is rotationally connected with a plurality of first connecting rods 3, the surface of the first connecting rod 3 is slidingly connected with a support rod 4, the bottom of the support rod 4 is provided with a reinforcement mechanism 5 for reinforcement, the surface of the first reinforcement block 1 on one side is installed with a first bolt 7, the surface of the first reinforcement block 1 on the other side is provided with a first nut 8 adapted to the first bolt 7, a connecting plate 9 is installed on the inner side of the support rod 4, the inner side of the connecting plate 9 is rotationally connected with a second connecting rod 10, and the inner side of the first connecting rod 3 is provided with two second reinforcement blocks 11.
[0027] In a specific embodiment of the utility model, the column is clamped from both sides by the first reinforcement block 1, and then the device is fixed by the reinforcement mechanism 5, and the length of the support rod 4 is adjusted on the surface of the first connecting rod 3, so that the second reinforcement block 11 clamps the column for the second time, effectively increasing the chassis support area and support points of the crane column, thereby realizing the reinforcement of the crane column, thereby reducing the probability of the column tipping over.
[0028] Specifically, the reinforcement mechanism 5 includes a reinforcement seat 501 arranged below the support rod 4, a damper 502 is installed on the surface of the reinforcement seat 501, a buffer spring 503 is installed on the surface of the damper 502, a third reinforcement block 504 is installed at one end of the damper 502, and the third reinforcement block 504 is slidably connected to the inside of the reinforcement seat 501, the support rod 4 is rotatably connected to the surface of the third reinforcement block 504, the reinforcement mechanism 5 also includes a sliding groove 505 opened on the inner wall of the reinforcement seat 501, both sides of the third reinforcement block 504 are provided with sliding protrusions 506 adapted to the sliding groove 505, and the sliding protrusions 506 are slidably connected to the surface of the sliding groove 505, the width of the top of the third reinforcement block 504 is greater than the width of the reinforcement seat 501, and the length of the damper 502 is less than the length of the inner wall of the reinforcement seat 501.
[0029] In a specific embodiment of the present utility model, when the column is subjected to external force, the force will be transmitted to the third reinforcement block 504 through the support rod 4, and the third reinforcement block 504 will transmit the force to the damper 502 and the buffer spring 503. At this time, the damper 502 and the buffer spring 503 will absorb the force and charge it, thereby increasing the supporting effect on the support rod 4. When the third reinforcement block 504 moves, it drives the sliding protrusion 506 to move on the surface of the sliding groove 505, thereby limiting the moving trajectory of the third reinforcement block 504 and increasing the force on the support rod 4. By setting the size of the third reinforcement block 504, it is convenient for the third reinforcement block 504 to move on the surface of the reinforcement seat 501, and the supporting effect on the support rod 4 is increased.
[0030] Specifically, a plurality of mounting blocks 6 are mounted on the surface of the reinforcement mechanism 5 , and mounting holes are formed on the surfaces of the mounting blocks 6 .

[0032] Specifically, the plurality of second connecting rods 10 are rotatably connected to the surfaces of the two second reinforcement blocks 11 respectively.
[0033] In a specific embodiment of the present utility model, the second connecting rod 10 is rotatably connected to the surface of the second reinforcing block 11 , so as to facilitate the adjustment of the height of the second reinforcing block 11 .
[0034] Specifically, a second bolt 12 is installed on the surface of the second reinforcement block 11 on one side, and a second nut 13 adapted to the second bolt 12 is installed on the surface of the second reinforcement block 11 on the other side.
[0035] In a specific embodiment of the present utility model, the second bolts 12 and the second nuts 13 are used in coordination to conveniently limit the two second reinforcement blocks 11 on the surface of the column.
[0036] Working principle: First, the column is clamped from both sides by the first reinforcement block 1, and then the reinforcement mechanism 5 is fixed by the mounting block 6, and the length of the support rod 4 is adjusted on the surface of the first connecting rod 3. The movement of the support rod 4 drives the connecting plate 9 and the second connecting rod 10 to move. At this time, the second reinforcement block 11 clamps the column for the second time, and the two second reinforcement blocks 11 are fixed by the second bolt 12 and the second nut 13. When the column is subjected to external force, the force will be transmitted to the third reinforcement block 504 through the support rod 4, and the third reinforcement block 504 will transmit the force to the damper 502 and the buffer spring 503. At this time, the damper 502 and the buffer spring 503 will absorb the force and charge it, thereby increasing the supporting effect on the support rod 4.
