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.
[0027] Depend on Figures 1 to 5The invention provides a telescopic arm body 1, wherein the telescopic arm body 1 comprises a fixed part 2 and a rotating part 3, wherein one end of the fixed part 2 is provided with a connecting shaft 4, wherein the rotating part 3 is rotatably connected to the rotating shaft, wherein one end of the fixed part 2 is fixed with a mounting plate 5 located below the rotating shaft, wherein the mounting plate 5 is rotatably connected with a long arc plate 6, wherein one end of the long arc plate 6 away from the mounting plate 5 is rotatably connected with a short arc plate 7, wherein one end of the short arc plate 7 away from the long arc plate 6 is fixed with a connecting plate 8, wherein a plug hole is provided on the connecting plate 8, and it should be noted that the axial center distance between the rotating end of the short arc plate 7 and the plug hole is the same as that between the connecting shaft 4 and the long arc plate 6. The axial center distances of the rotating ends are equal (the short sides of the parallelogram are equal), an angle sensor 9 is provided on one side of the connecting plate 8, a monitoring panel is provided in the compartment of the forklift, an intelligent module is provided in the monitoring panel, the angle sensor 9 is connected to the monitoring panel by electrical signals, the monitoring panel will display the angle change of the rotating part 3 compared with the fixed part 2 in real time, and an alarm signal will be issued when it exceeds a certain range, a connecting pin 10 is provided on the angle sensor 9, the connecting pin 10 is coaxially fixed with the jack, a positioning plate 11 is fixed on one side of the rotating part 3, and the angle sensor 9 is fixed on the positioning plate 11;
[0028] The axial center distance between the connecting pin 10 and the connecting shaft 4 is equal to the axial center distance between the two ends of the long arc plate 6. A parallelogram is formed between the axial centers at the two ends of the long arc plate 6, the axial center of the connecting pin 10 and the axial center of the connecting shaft 4. Through the arrangement of the long arc plate 6, the short arc plate 7 and the angle sensor 9, according to the principle that the opposite sides of the diagonal of the parallelogram are equal, when the rotating part 3 rotates, the angle of the parallelogram changes, and the connecting pin 10 on the angle sensor 9 rotates accordingly. After measurement by the angle sensor 9, real-time data is fed back to the cabin of the forklift, and the driver can view the rotation angle of the rotating part 3 through the monitoring panel. When a certain angle is exceeded, an alarm message will be issued, thereby reducing the overload of the rotating part 3 and improving safety during work.
[0029] refer to Figures 4 to 6As shown, after the angle sensor 9 is installed on the positioning plate 11, when the positioning plate 11 is fixed to the rotating part 3, it is necessary to measure the axial center distances of the two ends of the long arc plate 6 to ensure that the axial center distances of the connecting pin 10 and the connecting shaft 4 are consistent with each other. However, the existing installation method is only through manual measurement and positioning, which is very time-consuming and labor-intensive. There are large errors in the measurement process, resulting in interference in the parallelogram structure. A connecting disk 12 is provided on the angle sensor 9, and the connecting pin 10 passes through the connecting disk 12 and is rotatably connected. A connecting tube 13 is coaxially sleeved on the connecting disk 12, and a connecting rod 14 is coaxially fixed to the end of the connecting tube 13 away from the connecting disk 12, and a sleeve 15 is coaxially slidably provided on the end of the connecting rod 14 away from the connecting tube 13, and the connecting rod 14 and the inner wall of the sleeve 15 are connected by a spring Connected, since the horizontal distance between the angle sensor 9 and the connecting shaft 4 is uncertain, the connecting rod 14 and the sleeve 15 can be telescopically adjusted, and a positioning rod 16 is fixed to the end of the sleeve 15 away from the connecting rod 14, and one end of the positioning rod 16 is coaxially arranged with the sleeve 15, and a U-shaped plate 17 is fixed to one end of the positioning rod 16.

Through the settings of the connecting tube 13, the connecting rod 14 and the U-shaped plate 17, the worker directly sets the connecting tube 13 on the connecting disk 12 of the angle sensor 9, and then clamps the U-shaped plate 17 on the connecting shaft 4. At this time, the worker can directly locate the position of the angle sensor 9 according to the change of the parallelogram, which is very convenient and quick.

Through the arrangement of the support rod 18, the auxiliary rod 19 and the arc plate 20, the support rod 18 and the two auxiliary rods 19 form a central positioning, and the connecting shafts 4 of different diameters are clamped while keeping the axis unchanged, which greatly improves the universality of the auxiliary installation assembly;
[0031] In order to facilitate the sleeve installation of the U-shaped plate 17 on the connecting shaft 4 , guide plates 22 are provided on the arc-shaped plates 20 of the two auxiliary rods 19 .
[0032] refer to Figure 4As shown, in order to prevent the short arc plate 7 from falling off during use, a guard plate 23 is provided at the rotating end of the long arc plate 6 and the short arc plate 7. The short arc plate 7 is located between the guard plate 23 and the long arc plate 6. The guard plate 23 can strengthen the support for the connection of the short arc plate 7.
[0033] refer to Figure 7 As shown, in order to facilitate the installation of the connecting cylinder 13 and the connecting disk 12 , a U-shaped strip 24 is provided at one end of the connecting cylinder 13 close to the connecting disk 12 , and a positioning pin 25 is fixed on the U-shaped strip 24 .
[0034] refer to Figure 5 As shown, it should be further supplemented that a flat groove 26 is provided on the connecting pin 10 , and the shape of the inserting hole is consistent with that of the connecting pin 10 .
[0035] When the utility model is used:
[0036] First, when positioning the angle sensor 9, the worker directly sets the connecting tube 13 on the connecting disk 12 of the angle sensor 9, and then clamps the U-shaped plate 17 on the connecting shaft 4. At this time, the worker can directly position the angle sensor 9 according to the change of the parallelogram;
[0037] Then, for the connecting shafts 4 with different diameters, the support rod 18 and the two auxiliary rods 19 form a center positioning, and the connecting shafts 4 with different diameters are clamped while keeping the axis unchanged;
[0038] Finally, according to the principle that the opposite sides of a parallelogram are equal, when the rotating part 3 rotates, the angle of the parallelogram changes, and the connecting pin 10 on the angle sensor 9 rotates accordingly. After measurement by the angle sensor 9, real-time data is fed back to the cabin of the forklift. The driver can view the rotation angle of the rotating part 3 through the monitoring panel, and an alarm message will be issued when it exceeds a certain angle.
