DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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] The utility model provides Figure 1-Figure 7The AGV transport trolley shown includes a body 1, a loading platform 2 is arranged on the top of the body 1, and a plurality of positioning members 3 for limiting the angle steel are arranged on the loading platform 2; the loading platform 2 can be set as a lifting structure, and the specific structure and principle of the loading platform 2 and the body 1 are prior art, and reference can be made to the comparative document (Announcement No. CN217048860U, named as an automatic lifting AGV transport trolley), which will not be described in detail here;

[0028] Each positioning member 3 includes a first positioning plate 31 and a second positioning plate 32 which are distributed in an inverted V shape, and the top end of the first positioning plate 31 and the top end of the second positioning plate 32 are hinged to each other;

[0029] The worktable 2 is also provided with an adjustment mechanism 5 for facilitating the opening and closing of the first positioning plate 31 and the second positioning plate 32, and the adjustment mechanism 5 includes a concave cavity opened on the worktable 2, and a first connecting plate 51 and a second connecting plate 52 respectively connected to the bottom ends of the first positioning plate 31 and the second positioning plate 32, and an elastic member is provided in the concave cavity for driving the first connecting plate 51 and the second connecting plate 52 to move relative to each other.

[0030] Specifically, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the elastic member includes a partition 53 vertically fixed in the middle of the cavity, and a straight rod 54 horizontally installed in the cavity, the straight rod 54 passes through the partition 53, and springs 55 are fixed on both sides of the partition 53, the opposite ends of the two springs 55 are respectively connected to the first connecting plate 51 and the second connecting plate 52, and the two springs 55 are both sleeved on the outside of the straight rod 54.

[0031] When storing the angle steel of the power tower, the angle steel can be stacked on the loading platform 2, then transported to the storage location by the vehicle body 1, and then unloaded from the loading platform 2, thereby completing the storage of the angle steel;

[0032] When the angle steels are stacked on the loading platform 2, the angle steels can be sequentially clamped on the positioning members 3 on the loading platform 2, that is, the angle steels are limited by the first positioning plate 31 and the second positioning plate 32, so as to facilitate the orderly stacking of the angle steels on the loading platform 2, prevent the angle steels from slipping during transportation, and facilitate the stable transportation of the angle steels;

[0033] When the angle steel specifications are different, the angle steels are sequentially clamped on the positioning member 3. At this time, as the number of angle steels increases, their weight continues to increase, so as to press the first positioning plate 31 and the second positioning plate 32 downward, so that the first connecting plate 51 and the second connecting plate 52 at the bottom ends of the first positioning plate 31 and the second positioning plate 32 move relatively along the straight rod 54, so that the angle between the hinge ends of the first positioning plate 31 and the second positioning plate 32 gradually increases, until the first positioning plate 31 and the second positioning plate 32 fit on the inner wall of the angle steel, so that the positioning member 3 is opened and the spring 55 is stretched. After the angle steel is unloaded, the first connecting plate 51 and the second connecting plate 52 are pulled to move along the straight rod 54 under the action of the spring 55. Then the first connecting plate 51 and the second connecting plate 52 drive the first positioning plate 31 and the second positioning plate 32 to rotate, so that the angle between the hinge ends of the first positioning plate 31 and the second positioning plate 32 gradually becomes smaller, thereby realizing the automatic closing and resetting of the positioning member 3, thereby facilitating the limiting of angle steels of different specifications and facilitating the stable transportation of angle steels of different specifications.

[0034] Furthermore, if Figure 5-Figure 7 As shown, the tops of the first positioning plate 31 and the second positioning plate 32 are both formed into arc ends by arc transition.

[0035] When the angle steel is clamped on the first positioning plate 31 and the second positioning plate 32, the arc end can facilitate the top of the first positioning plate 31 and the second positioning plate 32 to fit with the inner wall of the angle steel, which is beneficial to the positioning of the angle steel and convenient for the stacking of the angle steel.

[0036] Furthermore, if Figure 5 and Figure 7 As shown, a connection frame 33 is installed on the arc end of the first positioning plate 31 , and a connection bar 34 is fixed on the arc end of the second positioning plate 32 . The connection bar 34 is inserted into the connection frame 33 and is rotatably connected to the connection frame 33 .

[0037] During the rotation and opening and closing process of the first positioning plate 31 and the second positioning plate 32, the connecting strip 34 rotates in the connecting frame 33 to realize the rotational connection between the first positioning plate 31 and the second positioning plate 32, thereby facilitating the opening and closing adjustment of the first positioning plate 31 and the second positioning plate 32, and is conducive to limiting the angle steels of different specifications.

[0038] Furthermore, if Figure 3 and Figure 6 As shown, two limit bars are installed at the inner bottom of the cavity, and the bottoms of the first connecting plate 51 and the second connecting plate 52 are provided with limit grooves, and the limit grooves are slidably connected to the limit bars, and the two limit bars are symmetrically distributed on both sides of the partition 53.

[0039] When the spring 55 pushes the first connecting plate 51 and the second connecting plate 52 to move relative to each other in the concave cavity, the first connecting plate 51 and the second connecting plate 52 can slide along the limiting strip through the limiting groove to limit the first connecting plate 51 and the second connecting plate 52 to ensure stable sliding of the first connecting plate 51 and the second connecting plate 52.

[0040] In addition, in one embodiment, if Figure 1-Figure 4 As shown, a lifting mechanism 4 is also provided on the vehicle body 1, and the lifting mechanism 4 includes storage cavities 46 symmetrically opened on both sides of the top of the vehicle body 1, and a lifting plate 41 arranged in the two storage cavities 46, and a power part for driving the lifting plate 41 to rise and fall is also provided inside the vehicle body 1.

[0041] The power part includes a cavity 47 symmetrically opened on both sides of the interior of the vehicle body 1, the cavity 47 is connected to the storage cavity 46, and a motor 44 and a fixing plate 45 are installed in the cavity 47, the fixing plate 45 is located above the main shaft of the motor 44, and a screw rod 43 is rotatably installed between the top of the fixing plate 45 and the top of the cavity 47, a connecting block 42 is fixed to one side of the lifting plate 41, and the connecting block 42 is located in the cavity 47 and is screwed to the outside of the screw rod 43, and the motor 44 is used to drive the screw rod 43 to rotate.

[0042] When the vehicle body 1 transports the angle steel to the storage location, the motor 44 can be used to drive the screw rod 43 to rotate, so that the screw rod 43 drives the connecting block 42 to rise along the cavity 47, and then the connecting block 42 drives the lifting plate 41 to rise from the storage cavity 46, so that the lifting plate 41 lifts the angle steel stacked on the loading platform 2, so as to facilitate the rapid removal of the stacked angle steel from the loading platform 2, thereby improving the unloading efficiency; and after unloading, the motor 44 can be used to drive the screw rod 43 to rotate in the opposite direction, so that the screw rod 43 drives the connecting block 42 to descend along the cavity 47 until the lifting plate 41 is lowered into the storage cavity 46, thereby realizing the storage of the lifting plate 41, which is convenient for the AGV to transport the angle steel later.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
