DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution: an AGV trolley frame that is convenient for expanding the use area, including a body 1, a first support frame 2, a motor 3, a transmission rod 4, a gear 5, a first rack 6, a second rack 7, a second support frame 8, a fixed plate 9, a fixed rod 10, a first mounting rod 11, a support plate 12, a sliding plate 13, a first hole groove 14, a second mounting rod 15, a second hole groove 16, a sliding block 17 and a spring 18.

[0024] When using the AGV trolley frame that is easy to expand the use area, if Figure 1 and Figure 3 As shown, a motor 3 is installed at the lower end of the middle part of the first support frame 2, and a transmission rod 4 is installed at the upper end of the motor 3, and a gear 5 is installed at the upper end of the transmission rod 4, a first rack 6 is provided on the front side of the gear 5, and a second rack 7 is provided on the rear side of the gear 5, and a second support frame 8 is installed on the left and right ends of the first rack 6 and the second rack 7, and a fixing plate 9 is provided on the inner wall of the upper and lower ends of the first support frame 2, and a fixing rod 10 is connected to the front and rear sides of the fixing plate 9. First, adjust the force support area of the AGV trolley frame according to the size of the supported object, start the motor 3 and drive the gear 5 to rotate through the transmission rod 4, and the front and rear ends of the gear 5 are connected. The two ends are respectively connected with the first rack 6 and the second rack 7 in a meshing manner, so the rotation of the gear 5 drives the first rack 6 and the second rack 7 to move to the left and right, and the first rack 6 and the second rack 7 drive the second support frame 8 to move to the left and right, and the second support frame 8 drives the fixing plate 9 to slide along the outside of the fixing rod 10 and extend from the inside of the first support frame 2, thereby helping to increase the force area when the object is displaced. At this time, the upper end of the first support frame 2 can be brought into contact with the bottom of the shelf to be transported, and the vehicle body 1 can be started to transport it. This is the method of using the AGV trolley frame that is easy to expand the use area;

[0025] When multiple objects need to be moved collectively, such as Figure 1 、 Figure 2 and Figure 4As shown, a first mounting rod 11 is installed at the upper end of the first supporting frame 2, and a supporting plate 12 is installed at the upper end of the first mounting rod 11, and sliding plates 13 are provided inside the left and right ends of the supporting plate 12, and first hole grooves 14 are provided inside the left and right ends of the sliding plate 13, and a second mounting rod 15 is installed inside the first hole groove 14, and a second mounting rod 15 is provided inside the upper end of the second mounting rod 15. A second hole groove 16 is connected to the inside of the second hole groove 16, and a spring 18 is provided on the outer side of the middle of the sliding block 17. First, the upper ends of the front and rear sides of the first supporting frame 2 are connected to the first mounting rod 11 in a threaded manner, and then the first supporting frame 2 is screwed together. After the first and second mounting rods 11 and 15 are installed in the positions of the first and second mounting rods 11, the front and rear sides of the support plate 12 are connected to the first mounting rod 11, and the support plate 12 is fixed in position by installing nuts on the upper ends of the first mounting rods 11. After installation, the first holes 14 set at the left and right ends of the sliding plate 13 are engaged with the upper ends of the second mounting rods 15. Before engaging, the sliding block 17 needs to be slid to the left and right sides to squeeze the spring 18. When the upper end of the second mounting rod 15 is completely entered into the first hole groove 14, the sliding block 17 stops squeezing the spring 18. The spring 18 rebounds and drives the sliding block 17 to engage with the second hole groove 16 inside the upper end of the second mounting rod 15, so that the sliding plate 13 and the second mounting rod 15 are stably connected, thereby meeting the demand for carrying multiple objects at the same time.
