[0025] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments.

[0026] As shown in the drawings, Figures 1-10 The flexible guide frame of the container spreader of the present embodiment comprises a first guide frame 10 and a second guide frame 20, and an elastic guide plate 30 is connected between the first guide frame 10 and the second guide frame 20, and the elastic guide plate 30 can be bent and deformed; the end of the first guide frame 10 is provided with a hinged plate 11, and the hinged plate 11 is used to be connected with the end beam 100 of the container spreader; the end of the second guide frame 20 is provided with a guide piece 40, and the guide piece 40 comprises a first guide piece 41 and a second guide piece 42, and the first guide piece 41 and the second guide piece 42 are both obliquely connected on the second guide frame 20, and the included angle of the first guide piece 41 and the second guide piece 42 is an obtuse angle.

[0027] The flexible guide frame structure of the container spreader in this embodiment is robust, reliable, and has a long service life. The inclined guide plates 40 facilitate alignment and positioning between the spreader and the container, reducing the precision requirements for driver operation and improving container loading and unloading efficiency. The elastic guide plate 30 is bendable and deformable (e.g., Figure 9 , Figure 10 As shown, if the guide frame collides with the container during the positioning process, the elastic guide plate 30 can undergo bending deformation in the direction of stress, which can reduce the impact force between the guide frame and the container, reduce component damage caused by the collision, and reduce safety hazards.

[0028] The elastic guide plate 30 can be made of polyurethane (PU) elastomer, rubber, or silicone, and can undergo elastic deformation and bending deformation, which can realize the automatic reset of the elastic guide plate 30.

[0029] Preferably, the elastic guide plate 30 has an embedded elastically deformable metal spring (not shown in the figure). The metal spring can be a rectangular sheet structure and can be arranged along the length of the elastic guide plate 30. When the elastic guide plate 30 bends and deforms, the metal spring will also bend and deform accordingly. The elastic force of the metal spring can help the elastic guide plate 30 to automatically return to its original position, so as to enable the guide frame to be used repeatedly and extend the service life of the guide frame.

[0030] The first guide frame 10 is a rigid integral component, which makes the first guide frame 10 structurally stable and reliable, and has a long service life.

[0031] The first guide frame 10 includes two parallel first guide plates 12 spaced apart, and a second guide plate 13 perpendicularly disposed between the two first guide plates 12. The two first guide plates 12 and the second guide plate 13 form a U-shaped first opening groove. The first guide frame 10 has a groove structure, which on the one hand makes the first guide frame 10 structurally stable and reliable with a long service life, and on the other hand facilitates the connection of the elastic guide plate 30 on the first guide frame 10.

[0032] The second guide frame 20 is a rigid integral component, which makes the structure of the second guide frame 20 stable and reliable, and has a long service life.

[0033] The second guide frame 20 includes two parallel third guide plates 21 spaced apart, and a fourth guide plate 22 perpendicularly disposed between the two third guide plates 21. The two third guide plates 21 and the fourth guide plate 22 form a U-shaped second opening groove. The second guide frame 20 has a groove structure, which on the one hand makes the second guide frame 20 structurally stable and reliable with a long service life, and on the other hand facilitates the connection of the elastic guide plate 30 on the second guide frame 20.

[0034] The two ends of the elastic guide plate 30 are respectively inserted between the first opening slot and the second opening slot.

At the same time, the width of the elastic guide plate 30 is equal to the width of the fourth guide plate 22, and the height of the elastic guide plate 30 is equal to the width of the third guide plate 21, so that the elastic guide plate 30 can be stably and effectively inserted into the second opening slot.

[0036] In this embodiment, the number of the hinge plates 11 is two, and the two hinge plates 11 are respectively arranged at the end portions of the two first guide plates 12. The hinge plate 11 and the first guide plate 12 are substantially perpendicular to each other, which can facilitate the connection of the guide frame to the end beam 100 and the rotation of the guide frame.
