[0026] In this embodiment, the base further includes a bearing seat 4 having a bowl-shaped groove and a bowl-shaped positioning cover plate 5. The base further includes a supporting ball 6 that can be driven to roll around its own center. The bearing seat 4 is detachably fixed on the top surface of the walking seat 2, which is convenient for maintenance and assembly of other structural components.

[0027] The bowl-shaped groove is formed by a hemispherical depression downward in the middle of the top surface of the bearing seat 4, and the bowl-shaped groove is used to assemble the charging box 1; the positioning cover plate 5 is spherical and fits the bowl-shaped groove. More specifically, the bowl-shaped groove of the bearing seat 4 is fit to the shape of the positioning cover plate 5, and the positioning cover plate 5 is detachably installed in the bowl-shaped groove of the bearing seat 4;

[0028] The purpose of the detachable assembly is to limit the support ball 6 and facilitate the assembly of the support ball 6; the detachable connection method adopts the bolt 7 connection method in this solution,

[0029] There are a plurality of supporting balls 6, a plurality of functional holes are provided on the positioning cover plate 5, and a plurality of ball mounting positions are provided in the bowl-shaped groove. The number of the functional holes and the number of the ball mounting positions are consistent with the number of supporting balls 6. After the positioning cover plate 5 is fixed on the bearing seat 4, the functional holes and the ball mounting positions are arranged in a one-to-one correspondence, and each supporting ball 6 is correspondingly limited in the corresponding ball mounting position by a functional hole; in this scheme, a plurality of supporting balls 6 are distributed in the bowl-shaped groove in an annular scattered shape;

[0030] The supporting ball 6 has a bearing end extending out of the functional hole, and the supporting ball 6 supports the charging box 1 in the bowl-shaped groove of the bearing seat 4 through the bearing end; more specifically, the outer end points of the bearing ends of several supporting balls 6 are located on the same spherical surface, and the charging box 1 has a spherical contact surface, which coincides with the spherical surface, and several supporting balls 6 support the charging box 1 through the contact surface; so that the charging box 1 can swing at any position in the bowl-shaped groove of the bearing seat 4.

[0031] In this embodiment, the base is further provided with a front connecting pull ring 8 and a rear connecting pull ring 9, and the front connecting pull ring 8 and the rear connecting pull ring 9 are relatively arranged on the base; more specifically, the front connecting pull ring 8 and the rear connecting pull ring 9 are arranged on the front end surface and the rear end surface of the bearing seat 4, and the front and rear corresponding Figure 1 The front and rear of the middle bearing seat 4 in the length direction are not described here; the front connecting pull ring 8 and the rear connecting pull ring 9 are arranged to adapt to the needs of ground material transportation, and it is convenient to adjust the use position of the overall structure, and it is more versatile.

[0032] In this embodiment, the lifting assembly includes a suspension rod 10 and an elastic member 11. The suspension rod 10 is driven to rise and fall. The suspension rod 10 is connected to the base through the elastic member 11. The elastic member 11 has an elastic force to reset the suspension rod 10. The suspension rod 10 is connected through the elastic member so that the suspension rod 10 is driven to stretch the elastic member 11 during lifting, and the suspension rod 10 rises from the base. In the non-lifting state, the suspension rod 10 is driven by the elastic member 11 to retract into the base. More specifically, the bearing seat 4 has a guide hole for accommodating the suspension rod 10. The guide hole is opened in the vertical direction, the guide hole is a long rectangular hole, the suspension rod 10 is a rectangular rod adapted to the guide hole, and has a self-locking anti-rotation function, which can improve the stability of the hoisting operation and prevent the overall structure from swinging due to deflection force. The top of the suspension rod 10 has a lifting ring 12, and the bottom end of the suspension rod 10 is connected to the bottom of the guide hole through an elastic member 11. The elastic member 11 has an elastic force parallel to the extension direction of the guide hole, so that the suspension rod 10 is guided to rise or reset in the guide hole, and the structural stability is better;

[0035] The boom 10 is driven to rise and fall in the height direction and is arranged on the bearing seat 4. After the boom 10 is driven to rise, the blocking surface 15 contacts the force-bearing surface 16, and the blocking surface 15 forms a blockage for the force-bearing surface 16. By simply coordinating the anti-breaking cavity 13 and the force-bearing seat 14, the movement of the boom 10 can be regulated within a specified range, and the hoisting stability and the anti-hoisting ability of the structure are better.

[0036] The elastic member 11 connects the bottom surface of the force-bearing seat 14 to the base; the bottom surface of the force-bearing seat 14 protrudes downward to form a support 17 to improve the tensile resistance. More specifically, when the force-bearing seat 14 is reset by the elastic member 11, the bottom surface of the support 17 is in contact with the top surface of the walking seat 2. The walking seat 2 has an elastic member 11 guide limit cavity for accommodating the elastic member 11, and the elastic member 11 is hidden in the elastic member 11 guide limit cavity of the walking seat 2. The force-bearing seat 14 is connected to the walking seat 2 through a plurality of elastic members 11, and the plurality of elastic members 11 are evenly distributed on the bottom surface of the force-bearing seat 14, so as to improve the structural reset ability, improve the safety, and avoid the danger caused by the breakage of a single elastic member 11. The elastic member 11 is a spring in this scheme, and it can also select any component with elastic force according to actual conditions, such as an elastic belt or a rubber strip, etc., which will not be repeated here.

[0037] In this embodiment, it also includes a protective coating 18 connecting the loading box 1 and the hanging rod 10, the protective coating 18 covers the top edge of the loading box 1 to prevent materials from entering the gap between the loading box 1 and the base, the protective coating 18 is reserved with an extension section, and the protective coating 18 expands the extension section corresponding to the rise of the hanging rod 10, and the expanded extension section is located on the upper side of the top edge of the loading box 1, which approximately increases the height of the loading box 1, thereby improving the protection of the materials in the loading box 1; the lifting components are several groups evenly distributed around the loading box 1, which improves the stability and safety of lifting, can reduce the difficulty of production management, and improve construction safety.

[0038] The protective coating 18 can be made of a tensile, wear-resistant and puncture-resistant Kevlar material. The reserved stretching section is stretchable. When the stretching section is unfolded accordingly, a slope surface toward the center of the charging box 1 is formed. The protective coating 18 also connects the base and the boom 10, and reserves a corresponding stretching section to form a protective structure that prevents the external environment from affecting the boom 10, thereby improving the reliability and safety of the lifting of the boom 10. More specifically, the inner end of the protective coating 18 covers and fixes the top edge of the charging box 1. The protective coating 18 is provided with a plurality of protective layers. The outer end of 8 covers the top edge of the base and is fixed thereto, and the boom 10 is arranged on the base through the protective coating 18. The protective coating 18 located around the boom 10 has a reserved extension section so that when the boom 10 rises, the top edge height of the loading box 1 is approximately raised, thereby improving the protection of the material inside the loading box 1. In addition, due to the large area coverage of the protective coating 18, the material in the loading box 1 can be prevented from spilling. In addition, the structure can also keep the loading box 1 in an open upward posture at all times, limit its swing amplitude, and improve the safety of material transportation.

[0039] In this embodiment, the boom 10 is also connected to the loading box 1 through a connecting rope 19, and the connecting rope 19 has a reserved movable section; the setting of the connecting rope 19 can prevent the loading box 1 from over-tilting, limit its swing amplitude, and limit the loading box 1 during hoisting, thereby improving the safety of material transportation;

[0040] The connecting cable 19 is covered by the protective coating 18, which has a better structural aesthetics and better structural reliability, reduces corrosion of the connecting cable 19 by the external environment, improves safety in use, and reduces the number of maintenance times.
