[0039] Please refer to Figures 1 to 6The pin joint seat 320 comprises a cross beam seat body 321, elastic clamping plate parts 323 and locking pins 324. The cross beam seat body 321 is fixedly connected to the two sides of the lower end of the support 310. Two rows of pin joint holes 322 are horizontally formed on the cross beam seat body 321. Each row is provided with two pin joint holes 322. The elastic clamping plate parts 323 are arranged between the two pin joint holes 322 of each row. The two elastic clamping plate parts 323 are fixedly connected to the side walls of the cross beam seat body 321. The locking pins 324 are inserted into the two pin joint holes 322 of each row. The two ends of the elastic clamping plate parts 323 can block the two locking pins 324. The cross beam seat body 321 is inserted into the longitudinal beam 211. The two sides of the heightening frame 330 can be connected to the inner sides of the cross beam seat body 321. The cross beam seat body 321 can press the heightening frame 330 on the longitudinal beam 211. The two locking pins 324 are respectively inserted into the two through cabin pipes 220 at the same end of the longitudinal beam 211. When the heightening frame 330 is not installed, the cross beam seat body 321 is clamped on the longitudinal beam 211. The weight borne on the cross beam seat body 321 is pressed on the longitudinal beam 211. The pin joint holes 322 on the cross beam seat body 321 and the through cabin pipes 220 on the longitudinal beam 211 are aligned. The locking pins 324 are inserted through the pin joint holes 322 on the cross beam seat body 321 and the through cabin pipes 220. The cross beam seat body 321 is locked on the longitudinal beam 211 through the two locking pins 324. Then, the locking pins 324 are rotated to make the two ends of the elastic clamping plate parts 323 block the edges of the locking pins 324, thereby reducing the falling of the locking pins 324. When the heightening frame 330 is installed, the two locking pins 324 are taken out. The support frame structure 300 is hoisted to separate the cross beam seat body 321 from the longitudinal beam 211. The heightening frame 330 is installed in the inside of the cross beam seat body 321. The heightening frame 330 is pre-connected to the inside of the cross beam seat body 321 by using bolts. At this time, the bolts are not tightened. Since the cross beam seat body 321 is provided with bolt holes, the diameter of the bolt holes is greater than the outer diameter of the bolt rod, so that the heightening frame 330 has an activity allowance in the up-down direction. The support frame structure 300 is lowered. The cross beam seat body 321 presses the heightening frame 330 on the longitudinal beam 211. The position of the cross beam seat body 321 is adjusted to align the pin joint holes 322 of the lower row of the cross beam seat body 321 with the through cabin pipes 220 on the longitudinal beam 211. The bolts connected to the heightening frame 330 are tightened again to keep the heightening frame 330 connected on both sides and pressed on the longitudinal beam 211 by the cross beam seat body 321, thereby reducing the movement of the heightening frame 330. In addition, the pressure on the heightening frame 330 is applied to the longitudinal beam 211, thereby reducing the stress on the connecting bolts and the failure of the connection. After the heightening frame 330 is connected, the cross beam seat body 321 is locked on the longitudinal beam 211 through the locking pins 324 and the pin joint holes 322 of the lower row of the cross beam seat body 321, thereby increasing the height of the winding drum structure 400.

Pin connection holes 322 are formed in the two side plates 3212, the side plates 3212 are attached to both sides of the longitudinal beam 211, the pin connection holes 322 correspond to the through cabin pipe 220, and the locking pin 324 passes through the pin connection hole 322 on one of the side plates 3212, the through cabin pipe 220, and the pin connection hole 322 on the other side plate 3212 in sequence. The main body of the cross beam seat body 321 is formed by the two side plates 3212 and the base plate 3211, the strength of the connection between the side plates 3212 and the base plate 3211 is enhanced by the reinforcing plate 3213, the two side plates 3212 are inserted into both sides of the longitudinal beam 211, the base plate 3211 is directly or through the heightening stand 330 pressed on the upper side of the longitudinal beam 211, and the locking pin 324 is locked in sequence through the side plate 3212 on the outer side of the longitudinal beam 211, the through cabin pipe 220, and the other side plate 3212, so as to fix the cross beam seat body 321 on the longitudinal beam 211.

After the locking pin 324 is locked in the cross beam seat body 321, the locking pin 324 is rotated to make the edge of the locking pin 324 clamped on the buckle 3234, the rotation of the locking pin 324 is reduced, the elastic pieces 3233 are kept in the state of being blocked by the elastic pieces 3233, the situation that the locking pin 324 is separated from the cross beam seat body 321 due to the rotation of the locking pin 324 is reduced, and the locking pin 324 can be quickly connected through rotation. Through the elastic deformation of the elastic pieces 3233, the locking pin 324 can be separated from the elastic pieces 3233 by rotating the locking pin 324 again, so that the locking pin 324 can be easily and quickly disassembled.

[0042] Please refer to Figures 1 to 9The locking pin 324 comprises a pin body 3241, a limiting plate 3242 and a hand-held rod 3244. The limiting plate 3242 is fixedly sleeved at one end of the pin body 3241. The limiting plate 3242 is a waist-shaped plate. Two ends of the long axis direction of the waist-shaped plate are provided with clamping grooves 3243. The elastic sheet 3233 can block the long axis direction of the waist-shaped plate. The buckle 3234 can be clamped into the clamping groove 3243. The short axis direction of the waist-shaped plate can be separated from the elastic sheet 3233. The hand-held rod 3233 is fixedly connected to the end of the pin body 3241 close to the end of the limiting plate 3242. The pin body 3241 passes through the side plate 3212 outside the longitudinal beam 211, the through-cabin pipe 220 and the other side plate 3212 in sequence to be locked. The side plate 3212 outside the longitudinal beam 211 blocks the limiting plate 3242. The pin body 3241 and the limiting plate 3242 are driven to rotate through the hand-held rod 3244. The limiting plate 3242 is separated from the elastic sheet 3233 through the short axis of the limiting plate 3242. The limiting plate 3242 is rotated. The elastic sheet 3233 blocks the long axis edge of the limiting plate 3242. The buckle 3234 is clamped into the clamping groove 3243. The rotation of the limiting plate 3242 is limited. The rotation of the pin body 3241 is limited. The situation that the pin body 3241 strays out of the pin connection hole 322 of the side plate 3212 and the through-cabin pipe 220 is reduced. The situation that the pin connection of the pin body 3241 is invalid is reduced.
