Description

Technical Field

[0001] The present invention belongs to the technical field of mining machinery and equipment, and particularly relates to a battery quick replacement limiting mechanism for new energy underground trackless equipment. Background Art

[0002] In recent years, with the rapid development of technologies such as battery performance, electric drive, driverless, and artificial intelligence, and the continuous improvement of price competitiveness, coupled with the increasingly prominent series of problems of traditional underground trackless vehicles driven by diesel engines, such as high energy consumption, heavy pollution, high noise, low energy efficiency, and expensive operation and maintenance costs, the trend of the evolution of underground trackless equipment in mines towards pure electric intelligence has become increasingly prominent. In addition, the breakthroughs made in power battery technology and its control system provide a basis for the electrification of mine trackless equipment. The attention of each mining unit to pure electric trackless equipment has gradually increased, and trackless equipment manufacturers have also actively turned to the research and development of pure electric intelligent trackless equipment.

[0003] However, due to the limitations of production technology requirements, the batteries that provide power for new energy underground trackless equipment are all high-power, large-capacity, heavy-weight, and large-size. The rapid, stable, and safe replacement of power batteries has thus become a major problem. In the prior art, battery replacement mechanisms are often complex in structure and large in occupied space, and it is difficult to adapt to the narrow and complex underground operation environment. There is an urgent need for a quick replacement mechanism with a simple structure and accurate guiding and limiting to meet the requirements of the efficient and safe operation of new energy underground trackless equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a battery quick replacement limiting mechanism for new energy underground trackless equipment, so as to solve the problem that the batteries of new energy underground trackless equipment cannot be quickly replaced, and provide a battery guiding and limiting structure with a simple structure, safety, and reliability.

[0005] The technical solution of the present invention is: a battery quick replacement limiting mechanism for new energy underground trackless equipment, including a vehicle frame and a battery pack. A battery lifting mechanism is provided between the vehicle frame and the battery pack. The battery lifting mechanism is connected with a battery lifting oil cylinder. On both sides of the upper end of the vehicle frame, vehicle frame end wedge-shaped blocks are respectively connected, and on both sides of the lower end of the vehicle frame, concave blocks are respectively connected; on both sides of the upper end of the battery pack, battery end wedge-shaped blocks are respectively connected, and on both sides of the lower end of the battery pack, convex blocks are respectively connected; the vehicle frame end wedge-shaped blocks and the battery end wedge-shaped blocks are wedge-shaped structures that cooperate with each other, and the concave blocks and the convex blocks are guiding structures that can cooperate with each other.

[0006] The beneficial effects of the present invention are as follows: when the battery lifting cylinder is actuated, after the battery pack is lifted to a certain height by the battery lifting mechanism, the wedge block at the frame end cooperates with the wedge block at the battery end, the concave block and the convex block respectively. During this process, the wedge block at the frame end, the wedge block at the battery end, the concave block and the convex block have guiding and limiting functions for the battery pack in four directions of up, down, left and right, so that the battery pack is lifted to an accurate position and ensures that it is stable and does not move, which provides important technical support for the subsequent realization of automatic closing of the communicating vessel.

[0007] The present invention is applied to underground trackless equipment, the whole structure is simple, flexible and practical, and the structural design is reasonable. The present invention can also be used for other equipment on the surface or underground that needs to replace large-capacity batteries. BRIEF DESCRIPTION OF THE DRAWINGS

The frame 4 is connected to the power battery lifting mechanism 5, and both sides of the upper end of the frame 4 are respectively connected to the frame end wedge block 6, and both sides of the lower end of the frame 4 are respectively connected to the concave blocks 3.

[0012] The upper sides of the battery pack 8 are respectively connected to the battery end wedge block 7, and the lower sides of the battery pack 8 are respectively connected to the protrusion 2. The frame end wedge block 6 and the battery end wedge block 7 are mutually matched wedge structures, and the concave block 3 and the protrusion 2 are mutually matched guide structures.

[0013] When the battery lifting oil cylinder 1 operates, after the battery pack 8 is lifted to a certain height by the battery lifting mechanism 5, the frame-end wedge-shaped block 6 cooperates with the battery-end wedge-shaped block 7, and the concave block 3 cooperates with the convex block 2 respectively. During this process, the frame-end wedge-shaped block 6, the battery-end wedge-shaped block 7, the concave block 3 and the convex block 2 have the functions of guiding and limiting the battery pack 8 in the four directions of up, down, left and right, so that the battery pack 8 is lifted to the accurate position and its stability is ensured without displacement, providing important technical support for the subsequent automatic closing of the communicating vessel.

[0014] The present invention has the following specific effects in practical applications: Compact and practical structure: The present invention realizes four-dimensional guiding and limiting through the cooperation of the wedge-shaped blocks and the concave and convex blocks at the upper and lower ends, with a simple structure, less occupied space, and is suitable for the narrow underground environment.

[0015] Accurate and stable positioning: In the structure of the present invention, the wedge-shaped structure and the guiding structure work together to ensure that the battery pack 8 is accurately positioned during the lifting process, avoiding displacement, and providing a reliable basis for electrical connection.

[0016] Support for quick replacement: The structure of the present invention reduces manual adjustment through mechanical guiding and limiting, improves the battery replacement efficiency, and meets the continuous operation requirements of mining equipment.
