Description

Technical Field

[0001] The invention relates to the technical field of mine car movement, and in particular to a multifunctional backpack mine car moving device. Background Art

[0002] Electric locomotive ore transportation + auxiliary shaft ore extraction is a common combined ore transportation method in small and medium-sized mines. It mainly includes the movement of the mine car's loading and unloading tanks and ore transportation. Among them, the ore transportation process of the mine car is achieved by electric locomotive traction, and the loading and unloading of the mine car is mainly achieved by manual pushing. In addition, ground hooks, electric push-pull cart machines and other devices have gradually begun to be used in the movement of mine cars.

[0003] Among the above methods, electric locomotives can only be used in the process of transporting ore in mine cars, and are not suitable for loading and unloading tanks in mine cars; the method of manually pushing the cart has high physical labor intensity and high safety risks; although the ground hook has a simple structure, it can only be used for lowering the tank of the mine car, and cannot realize the action of loading the tank of the mine car; although the electric push-pull trolley machine can be used as a mine car moving device to drive the mine car to load and unload the tank and transport ore, it still has certain limitations.

[0004] For example, the patent with publication number CN204845952U discloses a remote-controlled electric push-pull trolley machine for mining and its control system. The trolley machine includes a body, a battery box, an electrical control box, a brake mechanism, a car grabbing mechanism, a driving mechanism, a motor and rail wheels. The trolley machine can freely enter the tank cage or move on the track of the parking lot under the drive of the motor, and use the gripping mechanism to automatically grab and release the mine car as quickly as a human hand. However, this trolley machine needs to release the mine car after pushing the mine car onto the tank, and the fixation of the mine car in the tank cage can only be achieved by controlling the car blocker in the tank after the tank entry sensor transmits the signal to the controller. The overall structure and control process of the trolley machine are relatively complex, and it can only perform a single mine car moving process, and the function is relatively single.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0033] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0034] like Figure 1-4As shown, the present invention provides a multifunctional backpack mining vehicle moving device, including a base 10, a moving mechanism, a lifting mechanism, a braking mechanism and a power supply mechanism;

[0035] The base 10 includes a bottom plate 11 and fixing seats 12 disposed at four corners of the bottom plate 11;

[0036] The moving mechanism includes a wheel assembly connected to the lower part of the fixing seat 12 and a wheel driving assembly connected to the wheel assembly;

[0037] The lifting mechanism includes a lifting drive disk 31 disposed in the middle of the top surface of the chassis 11, a lifting drive motor 32 for driving the lifting drive disk 31 to rotate, and a lifting assembly connected to the lifting drive disk 31; the lifting assembly performs a lifting movement as the lifting drive disk 31 rotates;

[0038] The brake mechanism includes brake assemblies disposed on both sides of the chassis 11, and the brake assemblies are connected to the lifting drive disc 31;

[0039] The power supply mechanism includes a battery module 51 for supplying power and a power supply mechanism for outputting electrical energy to the outside.

[0040] Through the above-mentioned method, the multifunctional backpack mine car moving device provided by the present invention is placed at the bottom of the mine car, and then the lifting mechanism is driven to perform lifting movement by rotating the lifting drive disk 31, so that the mine car can be lifted in a state similar to being carried on the back; and the moving mechanism can also drive the mine car to move as a whole, completing the autonomous loading and unloading of the mine car and the ore transportation process, thereby realizing cross-mode movement between different transportation modes.

[0041] Specifically, the lifting drive disk 31 is symmetrically provided with a first fixed column 311 and a second fixed column 312, and the lifting assembly includes a first lifting assembly connected to the first fixed column 311 and a second lifting assembly connected to the second fixed column 312. The first lifting assembly and the second lifting assembly have the same structure and are symmetrically arranged on both sides of the lifting drive disk 31. With such an arrangement, the first lifting assembly and the second lifting assembly can be used to lift the mine car together, thereby improving the stability of the lifting process. Since the first lifting assembly and the second lifting assembly have the same structure, only the structure of the first lifting assembly will be described in detail below, and the structure of the second lifting assembly will not be described in detail.

[0042] In some embodiments of the present invention, the first lifting assembly includes a transmission assembly connected to the first fixing column 311 and a mine car lifting rod 33 connected to the transmission assembly. Figure 5As shown, the mine car lifting rod 33 includes two symmetrically arranged first connecting rods 331, the first connecting rods 331 are L-shaped, the inflection points of the two first connecting rods 331 are connected by a first fixed shaft 332, and the ends of the short sides of the two first connecting rods 331 are connected by a second fixed shaft 333; the first fixed shaft 332 is rotatably connected to the upper part of the fixing seat 12, and the second fixed shaft 333 is connected to the transmission assembly. In this way, the rotation of the lifting drive plate 31 can drive the transmission assembly to move, thereby driving the mine car lifting rod 33 to rotate around the first fixed shaft 332, so that the ends of the long sides of the first connecting rods 331 have a lifting effect.

[0043] More specifically, in some embodiments of the present invention, the transmission assembly includes a first connecting member 34 rotatably connected to the first fixed column 311, a second connecting member 36 connected to the first connecting member 34 through a first universal shaft 35, and a third connecting member 37 whose two ends are respectively rotatably connected to the second connecting member 36 and the second fixed shaft 333. In this configuration, when the lifting drive disk 31 rotates, the first fixed column 311 drives the first connecting member 34 to move around the circumference of the lifting drive disk 31, and then drives the second connecting member 36 to move in a direction close to or away from the lifting drive disk 31 through the first universal shaft 35, so that the third connecting member 37 pulls the mine car lifting rod 33 to rotate around the first fixed shaft 332.

[0044] In some embodiments of the present invention, the wheel assembly includes a first wheel assembly and a second wheel assembly of the same structure and symmetrically arranged; the first wheel assembly is arranged below the first lifting assembly, and the second wheel assembly is arranged below the second lifting assembly; the following only describes the structure of the first wheel assembly in detail, and the structure of the second wheel assembly is not repeated. The first wheel assembly includes an axle 22 and wheels 21 arranged at both ends of the axle 22. In some embodiments of the present invention, the wheel drive assembly is only connected to the first wheel assembly; the wheel drive assembly includes a wheel drive motor 25, and the output shaft of the wheel drive motor 25 is connected to the axle 22 through a belt drive assembly 26, which is used to drive the wheel 21 to rotate, so as to drive the entire mine car to move.

[0045] In some embodiments of the present invention, the first wheel assembly further includes a wheel lifting rod 23 and a fourth connecting member 24. The structure of the wheel lifting rod 23 is similar to that of the mine car lifting rod 33, including two symmetrically arranged second connecting rods 231, the second connecting rod 231 is L-shaped, the inflection points of the two second connecting rods 231 are connected by a third fixed shaft 232, the ends of the short sides of the two second connecting rods 231 are connected by a fourth fixed shaft, and the ends of the long sides of the two second connecting rods 231 are rotatably connected to the wheel axle 22; the third fixed shaft 232 is rotatably connected to the lower part of the fixed seat 12, and the two ends of the fourth connecting member 24 are rotatably connected to the second connecting member 36 and the fourth fixed shaft, respectively.

[0046] By the above method, the third connecting member 37, the fourth connecting member 24, the short side of the first connecting rod 331 and the short side of the second connecting rod 231 can form a structure similar to a quadrilateral. When the second connecting member 36 moves toward the direction close to the lifting drive plate 31, the second connecting member 36 pulls the third connecting member 37 and the fourth connecting member 24 at the same time, so that the angle between the third connecting member 37 and the fourth connecting member 24 is reduced, and the angle between the short side of the first connecting rod 331 and the short side of the second connecting rod 231 is reduced, so that the mine car lifting rod 33 rotates counterclockwise and the wheel lifting rod 23 rotates clockwise. Based on this, when the lifting drive plate 31 drives the lifting assembly to lift through the transmission assembly, the overall lifting range is effectively improved.

[0047] In some embodiments of the present invention, a first brake fixing member 111 and a second brake fixing member 112 are symmetrically arranged on both sides of the base 10, and the brake assembly includes a first brake assembly and a second brake assembly with the same structure and symmetrically arranged; the first brake assembly is connected to the first brake fixing member 111 and the first fixing column 311, and the second brake assembly is connected to the second brake fixing member 112 and the second fixing column 312; the following only describes in detail the structure of the first brake assembly, and does not repeat the structure of the second brake assembly.

[0048] The first brake assembly includes a brake link 41, a brake pad 42 rotatably connected to the first brake fixing member 111, and a connecting column 43 disposed on the top of the brake pad 42; one end of the brake link 41 is rotatably connected to the first fixing column 311, and the other end is connected to the connecting column 43 via a second universal shaft 44. With such a configuration, as the lifting drive disc 31 rotates, the brake link 41 can adjust the position of the brake pad 42 so as to adjust the braking state of the entire device. Specifically, in Figure 3In the state shown, if the lifting drive plate is rotated counterclockwise, the connecting column 43 is pushed outward through the brake connecting rod 41, so that the brake pad 42 rotates around the first brake fixing member 111, and the bottom of the brake pad 42 rotates inward. When the bottom of the brake pad 42 rotates inward to a certain extent, so that the brake pad 42 is closely attached to the outer wall of the track, the brake pad 42 is locked with the track, and the brake function is achieved, thereby fixing the vehicle. When the vehicle needs to move, the lifting drive plate 31 is rotated in the opposite direction, so that the bottom of the brake pad 42 can be rotated outward and away from the outer wall of the track, achieving the effect of releasing the brake, and the whole vehicle can be moved under the drive of the wheel drive motor 25.

[0049] In some embodiments of the present invention, the power supply structure includes a pantograph 52 rotatably connected to one end of the base 10, and the pantograph 52 is electrically connected to the battery module 51. More preferably, a fifth fixed shaft 522 is further provided at the end of the long side of the first connecting rod 331 in the mine car lifting rod 33, and the middle part of the pantograph 52 is rotatably connected to the fifth fixed shaft 522 through the pantograph connecting rod 521, so as to drive the pantograph 52 to be telescopic and folded during the lifting process.

[0050] In some embodiments of the present invention, the battery module 51 is arranged on the upper part of the chassis 11, which can not only be used to supply power to the internal mechanism of the multifunctional backpack mining vehicle mobile device that needs electricity, but also can supply power to other external mechanisms through the pantograph 52. The number of battery modules 51 and their connection methods can be set according to actual needs. A single battery module 51 can be used to supply power to different mechanisms, or corresponding battery modules 51 can be set for different power-consuming mechanisms to supply power, all of which belong to the protection scope of the present invention. A control module 60 can also be set on the upper part of the chassis 11 to control the multifunctional backpack mining vehicle mobile device provided by the present invention. Among them, the battery module 51 is preferably a rechargeable battery pack, which can be provided by setting a charging position on the brake pad 42 and electrically connecting the charging position to the battery module 51. Such a setting facilitates charging of the battery module 51.

[0051] The working principle of the multifunctional backpack mining vehicle moving device provided by the present invention is described below:

[0052] When the multifunctional backpack mining vehicle mobile device provided by the present invention is used, the lifting drive motor drives the lifting drive plate to rotate, so that the first fixed column 311 and the second fixed column 312 respectively drive the corresponding lifting assembly, wheel assembly and brake assembly to move. Figure 1-3In the state shown, the lifting drive disk is rotated counterclockwise, which pulls the transmission assembly inward and pushes the brake assembly outward, so that the transmission assembly drives the mine car lifting rod 33 to rotate counterclockwise, and drives the wheel lifting rod 23 to rotate clockwise, so as to achieve the overall lifting effect. And, after lifting to a certain extent, the lifting drive disk continues to rotate counterclockwise, so that after the brake assembly is pushed outward to a certain extent, the brake pad 42 is locked with the track, and the vehicle can be fixed. When the vehicle needs to move, the lifting drive disk 31 is rotated in the opposite direction to release the brake, and the whole vehicle can be moved under the drive of the wheel drive motor 25.

[0053] In summary, the multifunctional backpack mine car moving device provided by the present invention can lift the mine car as a whole from the bottom of the mine car by setting a lifting mechanism, so as to lift the mine car in a similar state to being carried on the back, and use the moving mechanism to drive the mine car as a whole to move, and can complete the autonomous tank loading, unloading and ore transportation process of the mine car, and realize cross-mode movement between different transportation modes. In addition, the multifunctional backpack mine car moving device provided by the present invention has a compact overall structure, a high degree of integrated mechanization, and is easy to control as a whole. It can realize multiple functions such as lifting, moving, fixing, charging, and power supply of the mine car, and has a good application prospect, and provides a new solution to the problem of autonomous ore transportation in small and medium-sized mines.

[0054] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
