[0026] like Figure 1 As shown, an automatic port loading and unloading transportation equipment includes a main beam 1, and support assemblies are symmetrically installed at the bottom of both ends of the main beam 1. The support assembly includes support legs 2 that are installed obliquely and symmetrically. The bottoms of the support legs 2 are connected together by a bottom beam 3. The main beam 1 and the support legs 2 form a triangular structure with the bottom beam 3, which can effectively resist external pressure and torsion, thereby ensuring the stability of the support. A walking beam 4 is installed below the main beam 1 through a number of oblique supports 7. A walking mechanism 8 is installed on the walking beam 4, and a clamping mechanism 9 is installed at the bottom of the walking mechanism 8. The middle positions of adjacent support legs 2 are connected together by a cross beam 5. An oblique beam 6 is installed between the center position of the cross beam 5 and the end of the walking beam 4. The oblique beam 6 and the cross beam 5 serve the purpose of reinforcing the support, making the gantry structure more stable, thereby ensuring safety during use.

[0027] like Figure 2As shown, the travel mechanism 8 includes a trolley 801, in which a travel motor 802 is installed. The travel motor 802 is connected to a pinion 803 via a transmission shaft. The pinion 803 meshes with a large gear 804. The large gear 804 is fixedly mounted on a driving wheel set 805. The driving wheel set 805 is located at the rear of the trolley 801. A driven wheel set 806 is mounted in front of the trolley 801 to cooperate with the driving wheel set 805. When the travel motor 802 is started, the pinion 803 begins to rotate, driving the large gear 804 meshing with it to rotate, thereby causing the driving wheel set 805 to move forward or backward, thereby driving the trolley 801 to move on the travel beam 4.

[0028] A hoisting motor 807 is mounted at the bottom of the trolley 801. The output shaft of the hoisting motor 807 is connected to a reel. A chain 808 is wound around the reel, and a hook 809 is mounted on the other end of the chain 808. When the hoisting motor 807 is started, the reel begins to rotate, and the chain 808 is wound around the reel, thereby driving the hook 809 to rise or fall.

[0029] The travel motor 802 and the hoisting motor 807 both use forward and reverse reduction motors. The use of the reduction motor is to increase the torque and reduce the speed, which enables the hoisting motor 807 to drive the heavy object smoothly and the travel motor 802 to transport the heavy object smoothly.

[0030] like Figure 3 、 4 As shown, the clamping mechanism 9 includes a connecting base 901 connected to the traveling mechanism 8. A lifting lug is mounted on the upper end of the connecting base 901, which is connected to the hook 809. A flat plate 902 is mounted on the lower end, which serves as a weighing device. Clamp assemblies are symmetrically mounted on the bottom of the flat plate 902. A downward pressure assembly is symmetrically mounted at the bottom center of the flat plate 902. An electrical control box 914 is mounted on one side of the top of the flat plate 902. This control box 914 controls the opening and closing of the clamp assemblies and the raising and lowering of the downward pressure assembly, thereby securing the cargo.

[0031] The clamp assembly includes a U-shaped groove 903 symmetrically mounted on the bottom of the flat plate 902 in the front-to-back direction. An opening and closing plate 904 is hingedly connected within the U-shaped groove 903. The lower ends of the opening and closing plates 904 are connected together via a clamp mounting plate 906. The upper end of one of the opening and closing plates 904 is fixedly connected to an opening and closing cylinder 911, which is controlled by an electrical control box 914. The opening and closing plates 904 are connected together by a connecting rod 905, which provides a stable connection and allows simultaneous movement of the opening and closing plates 904. Several clamping jaws 907 are symmetrically mounted on the lower end of the clamp mounting plate 906. These jaws 907 are arranged in an L-shape and can grip cargo inward. Several crossbars 908 are evenly spaced on the inner sidewall of the clamp mounting plate 906. A vertical plate 909 is mounted on the other end of each crossbar 908. Several clamping rods 910 are evenly spaced at the bottom of each vertical plate 909.

[0032] The pressing assembly includes a telescopic mechanism 912 symmetrically mounted on the bottom of the flat plate 902, and a lower pressing plate 913 is mounted on the telescopic end of the telescopic mechanism 912. The telescopic mechanism 912 can be a telescopic mechanism such as a cylinder, a hydraulic cylinder or an electric push rod, and the movement is controlled by an electric control box 914.

[0033] The action process of this utility model is as follows:

[0034] First, the clamping mechanism 9 is connected to the walking structure 8; then, the walking motor 802 is started and runs above the cargo, the opening and closing cylinder 911 is started, the clamping jaws 907 are opened, and the clamping jaws 907 move downward under the action of the hoisting motor 807 until the cargo is placed between the clamping jaws 907; after that, the opening and closing cylinder 911 is started, the clamping jaws 907 are closed, and the cargo is placed between the clamping jaws 907, and the transverse curved part of the clamping jaws 907 is located at the bottom of the cargo. According to the size of the cargo, if the cargo is large, the clamping rod 910 is placed on both sides of the cargo to achieve clamping; if the cargo is small, the telescopic mechanism 912 is started, driving the upper pressure plate 913 to rest on the upper end surface of the cargo, and clamping the upper and lower surfaces of the cargo together with the clamping jaws 907; finally, the hoisting motor 807 is started to lift the cargo. After it is lifted to a certain height, the walking motor 802 is started to transport the cargo to the specified position, the hoisting motor 807 drives the cargo to descend, and the opening and closing cylinder 911 is opened to realize the automatic loading and unloading transportation of the cargo.
