[0003] However, due to the special conditions of the mine, when maintenance personnel repair the equipment, the heavy parts that need to be replaced by the heavy robots are also quite heavy, and a lot of maintenance tools are needed. In addition, they need to carry the toolbox themselves, which increases the physical exertion of maintenance personnel. The current toolboxes not only have a small capacity and low mobility, but are also inconvenient to carry, which causes some trouble for maintenance personnel. Summary of the Invention

[0004] Therefore, this utility model provides a portable toolbox for the maintenance of mining electromechanical equipment to solve the problem that existing toolboxes are unsuitable due to the unfavorable environment of heavy mining machinery.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0040] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] Please refer to Figures 1-8. This utility model discloses a portable toolbox for the maintenance of mining electromechanical equipment. It can be stacked to improve portability, and an independent drive device is installed at the bottom of the toolbox to facilitate movement in the mining area. The following will describe this technical solution by way of specific embodiments.

[0042] As shown in Figures 1-3, in a specific embodiment of this utility model, the portable toolbox for mine machinery and equipment maintenance mainly includes a base panel 1, folding panels 3, and an independent drive device 5. The base panels 1 are arranged in pairs and connected by a telescopic base 2, which is a typical scissor structure that can freely switch between an extended and retracted state. Two folding panels 3 are arranged on both sides of the telescopic base 2, as shown in Figures 1-3. One end of each folding panel 3 is hinged to one base panel 1, and the other end is hinged to the other base panel 1. The two folding panels 3 fold inward symmetrically, thus completing the folding deformation when the telescopic base 2 retracts. Furthermore, the top of the base panel 1 is hinged to a folding bottom plate 4, and when the folding bottom plate 4 is folded down, it abuts against the telescopic base 2. This increases the load-bearing capacity of the toolbox. Additionally, when the folding bottom plate 4 is folded up, it can also be used as a handle to move the empty toolbox.

[0043] In this embodiment, two independent drive devices 5 are also installed at the bottom of the base plate 1. The drive devices 5 are located below the telescopic base 2 and are used to move or steer the toolbox. Specifically, the independent drive device 5 includes a stepper motor 51 and a triangular wheel frame 53. The single stepper motor 51 is driven by a battery, and the speed and angle of the motor are adjusted by a controller. The stepper motors 51 on the two independent drive devices 5 have their operating power controlled individually by the controller. On the other hand, the output shaft of the stepper motor 51 is coaxially connected to the drive wheel 54, and the drive wheel 54 is located at the center of the triangular wheel frame 53. Three driven wheels 52 are rotatably arranged on the front side of the triangular wheel frame 53. The three driven wheels 52 are frictionally connected to the drive wheel 54, thereby using the drive wheel 54 to drive the three driven wheels 52 to rotate. The driven wheels 52 contact the ground to move the toolbox. In terms of specific structure, three driven wheels 52 are evenly arranged on a triangular wheel frame 53, and a sleeve 55 is set at the center of the triangular wheel frame 53. The output shaft of the stepper motor 51 passes through the sleeve 55 and is connected to the driving wheel 54, so that the main shaft of the stepper motor 51 can rotate freely within the sleeve 55. When the driven wheels 52 encounter steps or obstacles, the triangular wheel frame 53 will flip under the action of the driven wheels 52, thereby directly overcoming the obstacles. The turning is achieved by using the differential action of the two stepper motors 51. In mining operations, this can improve the maneuverability of the toolbox.

[0044] In some embodiments, the base enclosure 1 includes a support base 11, two side plate hinge positions 14, and a bottom plate hinge position 15. A fixing frame 12 is provided on the top of the support base 11, and a wire mesh 13 is provided inside the fixing frame 12. Two side plate hinge positions 14 are provided on both sides of the fixing frame 12. The two side plate hinge positions 14 are adapted to be hinged with two folding enclosure panels 3. The folding bottom plate 4 rotates vertically around the bottom plate hinge position 15, and the folding enclosure panels 3 rotate laterally around the side plate hinge positions 14.

[0045] The folding enclosure 3 includes a single enclosure 31 and a connector 32. The connector 32 is located between the two single enclosures 31, and the two sides of the connector 32 are hinged to the two single enclosures 31. The two single enclosures 31 are respectively hinged to the side plate hinge positions 14 on the two base enclosures 1, thereby connecting the two base enclosures 1 together.

[0046] In some embodiments, as shown in Figure 7, the telescopic base 2 is formed by two bi-bar linkages 21 cross-mounted together. Each bi-bar linkage 21 is formed by two single links 22 hinged at their ends, with a positioning hole 24 at the hinge point. A straight groove 23 is provided in the middle of each single link 22, and the two overlapping straight grooves 23 are fixed with rivets. The rivets enhance the compressive strength of the telescopic base 2 without affecting its free movement. Furthermore, in this embodiment, when the telescopic base 2 is fully extended, the positioning hole 24 coincides with the position of the connector 32 on the folding panel. Fasteners are then used to fix the connector 32 to the positioning hole 24, further improving the structural stability of the toolbox when it is extended.

[0047] In some embodiments, the folding base plate 4 includes a handrail 41, a load-bearing net 42, and a limiting bar 43. The limiting bar 43 is hinged to the hinge joint 15 of the base plate. The limiting bar 43 is connected to the tail end of the load-bearing net 42 and is perpendicular to it. The handrail 41 is provided at the head end of the load-bearing net 42. The limiting bar 43 can effectively support the two folding panels 3 and the telescopic base 2 to prevent deformation, thereby improving the structural stability of the toolbox. As an optional technical solution, the tail end of the load-bearing net 42 is flexibly connected to the limiting bar 43 by a nylon rope, which allows the folding base plate 4 to be folded as well, further improving the portability of the toolbox.

The various components mentioned in this utility model are common technologies in the existing field. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
