DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes a highly automated truss machine, including a gantry 1, a loading and unloading assembly and two stable assemblies: the top of the gantry 1 is slidably connected to an electric sliding frame 2, both sides of the electric sliding frame 2 are equipped with electric lifting devices, and the two electric lifting devices are slidably connected to a lifting frame 3; the loading and unloading assembly includes a threaded rod 4 rotatably connected to the lower end of the lifting frame 3, a rotating motor 11 is installed at the lower end of the lifting frame 3, the end of the threaded rod 4 passes through the lifting frame 3 and is fixedly connected to the output end of the rotating motor 11, an infrared rangefinder 12 is installed at the bottom of the lifting frame 3, the infrared rangefinder 12 is electrically connected to the rotating motor 11, and the infrared rangefinder 12 and the rotating motor 11 are coupled to a closed loop with an external power supply and a circuit controller, a slider 17 is threadedly connected to the threaded rod 4, and a lifting hook 6 is fixedly connected to the bottom of the slider 17 through a supporting rod 5;

[0025] The electric lifting device is controlled to drive the lifting frame 3 to move downward, and the infrared rangefinder 12 at the bottom of the lifting frame 3 is used to measure the distance between the bottom of the lifting frame 3 and the top of the cargo. When the distance is exactly equal to the installation distance L between the lifting hook 6 and the cargo lifting ring, the infrared rangefinder 12 sends a signal to the circuit controller, and the electric controller transmits a start signal to the rotating motor 11 to start the rotating motor 11. The rotating motor 11 drives the threaded rod 4 to rotate, so that the slider 17 starts to move relative to the bottom of the lifting frame 3, thereby driving the lifting hook 6 to gradually approach the cargo lifting ring and match it. The lifting frame 3 can be lifted and transported by controlling the electric lifting device to lift it. When the cargo is unloaded, the electric lifting device drives the lifting frame 3 to move downward. When the infrared rangefinder 12 measures that the distance between the bottom of the lifting frame 3 and the cargo lifting ring is less than the installation distance L, the rotating motor 11 starts to start and rotates in the opposite direction, so that the slider 17 starts to drive the lifting hook 6 to move and the lifting hook 6 is separated from the cargo lifting ring, thereby improving the automation of loading and unloading of the cargo by the truss machine and improving the loading and unloading efficiency.

[0026] like Figure 1-Figure 2 As shown, a limiting hole is provided at the bottom of the lifting frame 3, the support rod 5 matches the limiting hole, and a support plate 16 is fixedly connected to the support rod 5, and the support plate 16 fits the bottom of the lifting frame 3;

[0027] The limiting hole and the abutment plate 16 can fully limit the movement of the support rod 5, thereby ensuring the movement stability of the lifting hook 6.

[0028] like Figure 1-Figure 4 As shown, each stabilizing assembly includes a T-shaped rack rod 7 fixedly connected to the support rod 5, a side plate 8 is fixedly connected to the bottom of the lifting frame 3, a rotating shaft 9 is rotatably connected to the outer wall of the side plate 8 through a bracket, and a transmission gear 10 is fixedly connected to the upper and lower ends of the rotating shaft 9, and the T-shaped rack rod 7 is meshed with the transmission gear 10 at the upper end of the rotating shaft 9;

[0029] During the matching process of the lifting hook 6 and the cargo lifting ring, the slider 17 drives the supporting rod 5 to move, so that the T-shaped rack rod 7 moves synchronously. The T-shaped rack rod 7 can drive the rotating shaft 9 and the transmission gear 10 at the lower end of the rotating shaft 9 to rotate by engaging with the transmission gear 10 at the upper end of the rotating shaft 9, thereby improving the linkage degree between the various structures and reducing the energy consumption of the device.

[0030] like Figure 1-Figure 3 As shown, a clamping component is provided on the outside of the side plate 8, and the clamping component includes a first slide rail and a second slide rail fixedly connected to the outer wall of the side plate 8, and a first rack plate 13 and a second rack plate 14 are slidably connected in the first slide rail and the second slide rail respectively, and the first rack plate 13 and the second rack plate 14 are mutually meshed with the transmission gear 10 at the lower end of the rotating shaft 9, and the ends of the first rack plate 13 and the second rack plate 14 are fixedly connected to a clamping rod 15, and a rubber pad is mounted on the clamping rod 15;

[0031] The first rack plate 13 and the second rack plate 14 are driven to move by the rotation of the transmission gear 10 at the lower end of the rotating shaft 9, so that the two clamping rods 15 on the first rack plate 13 and the second rack plate 14 begin to move toward each other, so that the clamping rods 15 can be used to firmly clamp the lifted goods to avoid shaking of the goods during the lifting and transportation process, thereby ensuring the stability of the goods under the transportation of the truss machine.

[0032] The detailed working process of the utility model is as follows:

[0033] 1. When the highly automated truss machine is used, firstly, the bottom center of the lifting frame 3 is aligned with the cargo lifting ring, and the electric lifting device is controlled to drive the lifting frame 3 to move downward. The infrared rangefinder 12 at the bottom of the lifting frame 3 is used to measure the distance between the bottom of the lifting frame 3 and the top of the cargo. When the distance is exactly equal to the installation distance L between the lifting hook 6 and the cargo lifting ring, the infrared rangefinder 12 sends a signal to the circuit controller, and the electric controller transmits a start signal to the rotating motor 11 to start the rotating motor 11. The rotating motor 11 drives the threaded rod 4 to rotate, so that the slider 17 starts to rise relatively. The bottom of the lowering frame 3 moves, thereby driving the lifting hook 6 to gradually approach the cargo lifting ring and match it. By controlling the electric lifting device to lift the lifting frame 3, the cargo can be lifted and transported. When the cargo is unloaded, the electric lifting device drives the lifting frame 3 to move downward. When the infrared rangefinder 12 measures that the distance between the bottom of the lifting frame 3 and the cargo lifting ring is less than the installation distance L, the rotating motor 11 starts to start and rotates in the opposite direction, so that the slider 17 starts to drive the lifting hook 6 to move and separate the lifting hook 6 from the cargo lifting ring, thereby improving the automation degree of loading and unloading of the cargo by the truss machine and improving the loading and unloading efficiency;

[0034] 2. In the process of matching the lifting hook 6 with the cargo lifting ring, the slider 17 drives the supporting rod 5 to move, so that the T-shaped rack rod 7 moves synchronously. The T-shaped rack rod 7 can drive the rotating shaft 9 and the transmission gear 10 at the lower end of the rotating shaft 9 to rotate by meshing with the transmission gear 10 at the upper end of the rotating shaft 9. Then, the first rack plate 13 and the second rack plate 14 can be driven to move by the rotation of the transmission gear 10 at the lower end of the rotating shaft 9, so that the two clamping rods 15 on the first rack plate 13 and the second rack plate 14 start to move toward each other, so that the clamping rods 15 can be used to firmly clamp the lifted cargo to avoid shaking of the cargo during lifting and transportation, thereby ensuring the stability of the cargo under the transportation of the truss machine.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
