Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a hoisting vehicle with a double limiting structure, including a vehicle body 1, a support base plate 2 installed at one top end of the vehicle body 1, a lifting assembly 3 fixedly connected to one top end of the support base plate 2, a telescopic boom 4 rotatably connected to the other top end of the support base plate 2, a winch 5 fixedly connected to one top end of the telescopic boom 4, a steel cable 6 rotatably connected inside the winch 5, a plurality of fixing blocks 7 fixedly connected to the other top end of the telescopic boom 4, the steel cable 6 horizontally passing through the interior of the fixing blocks 7, a rolling assembly 8 fixedly connected to one side of the telescopic boom 4, a limiting assembly 9 rotatably connected to both sides of the rolling assembly 8, a limiting stop 10 fixedly connected to one end of the steel cable 6, and an adjusting assembly 11 horizontally passing through the interior of the limiting stop 10.

[0024] The limiting component 9 includes a fixed plate 901 rotatably connected to both sides of the support frame 801. The fixed plate 901 is rotatably connected to the support frame 801 through a connecting rod 902. A limiting baffle 903 is fixedly connected to the lower inner side of the fixed plate 901.

[0025] The adjustment assembly 11 includes a motor 1101 embedded in one end of the limit block 10. The output shaft of the motor 1101 is connected to a bidirectional lead screw 1102. A first threaded collar 1103 and a second threaded collar 1104 are rotatably connected to the outer sides of the bidirectional lead screw 1102. A main hook 1105 is threadedly connected to the bottom of the first threaded collar 1103, and a secondary hook 1106 is threadedly connected to the bottom of the second threaded collar 1104.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the lifting assembly 3 includes a first connector 301 fixedly connected to one end of the top of the support base plate 2. A hydraulic rod 302 is fixedly connected to one end of the first connector 301, and a second connector 303 is fixedly connected to one end of the hydraulic rod 302. This design allows the telescopic boom 4 to be lifted and lowered. The process of lifting and lowering the telescopic boom 4 is achieved by changing the angle of the first connector 301 and the second connector 303, thereby lifting materials at different heights for unloading, increasing work efficiency. At the same time, the hydraulic rod 302 also provides a certain support for the lifting process, increasing the stability when lifting materials.

[0027] In this embodiment, as Figure 1 and Figure 3 As shown, the rolling assembly 8 includes a support frame 801 fixedly connected to one side of the telescopic boom 4. A rotating rod 802 is horizontally inserted through the inside of the support frame 801, and the outside of the rotating rod 802 is embedded inside the pulley 803. This design allows the steel cable 6 to slide on the pulley 803, which has a certain limiting function, reduces the possibility of the steel cable 6 detaching, prevents the steel cable 6 from being damaged due to prolonged contact with the steel structure, reduces costs, and increases safety.

[0028] In this embodiment, as Figure 1 and Figure 4 As shown, a slot is passed through the center of the limiting baffle 903, and a trapezoidal groove is provided at the bottom of the limiting baffle 903. Through this design, when the hoisted item rises to a certain height, it will contact the trapezoidal groove at the bottom of the limiting baffle 903, thereby stopping the hoisted item from rising. This increases the limiting effect, prevents the continuous rise of the hoisted item from damaging the parts, and also prevents the material from falling off after impact, thus increasing the safety during operation.

[0029] In this embodiment, as Figure 1 As shown, a fixed frame is fixedly connected to the top end of the vehicle body 1 where it fits against the telescopic boom 4. This design allows the telescopic boom 4 to remain inside the fixed frame when it is not in operation, providing a certain degree of stability. It also prevents the telescopic boom 4 from remaining on the vehicle body 1 for an extended period of time, thus avoiding damage to the vehicle body 1.

[0030] In the embodiment, as shown in Figure 1 and Figure 5 , the bidirectional screw rod 1102 is rotatably connected to the motor 1101; by this design, the main hook 1105 and the auxiliary hook 1106 can move oppositely under the driving of the bidirectional screw rod 1102, so that the distance between them can be changed, and the size of the hoisted material can be adjusted, and a certain limiting effect is achieved, and the versatility is increased.

[0031] In the embodiment, as shown in Figure 1 and Figure 5 , one end of the main hook 1105 is provided with a rectangular slot, and one end of the auxiliary hook 1106 is provided with a plug rod with the same size as the rectangular slot; by this design, the main hook 1105 and the auxiliary hook 1106 can be plugged according to the size of the hoisted material when the gap is adjusted, and the hoisted material will not fall off when the plugging is completed, and the safety and stability during hoisting of the material are increased.
