[0025] like Figures 1-4As shown, a shovel-type battery quick-change vehicle includes a transport flatbed trolley 3 and a hoisting system 2. The transport flatbed trolley 3 is externally connected to a traction system 1 for propulsion. The traction system 1 is a vehicle body powered by a diesel engine. This vehicle body is hinged to the transport flatbed trolley 3 via a pin shaft, allowing for flexible turning in tunnels. Three straight-line towing assemblies 4 are arranged parallel to the vehicle's length and width on the flatbed frame 3. The two straight-line towing assemblies 4 on both sides serve as second straight-line towing assemblies, operating synchronously. The middle straight-line towing assembly 4 serves as the first straight-line towing assembly. The two second straight-line towing assemblies are installed at the bottom of the flatbed frame 3.1, and the first straight-line towing assembly is aligned with the centerline in the width direction of the flatbed frame 3.1, installed in a slot in the middle of the flatbed frame 3.1.

[0026] The lifting system 2 straddles the transport flatbed trolley 3. The lifting system 2 includes two sets of lifting components. The two sets of lifting components move synchronously. The two sets of lifting components are slidably mounted on both sides of the flatbed frame 3.1 and are each connected to the moving end of a second linear towing component. The two sets of lifting components are connected by an upper crossbeam 2.6 to form a portal structure. The lifting ends of the two sets of lifting components are connected to the same battery hoist 2.4. The crossbeam 2.6, the lifting components, and the flatbed frame 3.1 form a passage that allows the battery to pass through. The battery hoist 2.4 is a winch crane.

[0027] A sliding trolley 6 is mounted on the top surface of the flatbed frame 3.1. The sliding trolley 6 includes a steel-welded body frame and rollers distributed at the bottom of the body frame. The sliding trolley 6 slides along the length of the vehicle. The sliding trolley 6 is connected to the moving end of the first linear towing assembly. The top surface of the sliding trolley 6 forms a battery carrying platform. A guide groove 3.3 is provided on the top surface of the flatbed frame 3.1 to restrict the sliding trolley 6. The width of the guide groove 3.3 is centered relative to the width of the flatbed frame 3.1, and the entrance of the guide groove 3.3 is a flared opening.

[0028] like Figure 2 , Figure 3 As shown, the linear towing assembly includes a double telescopic pushing cylinder 4.1. The two ends of the cylinder rod of the double telescopic pushing cylinder 4.1 are fixedly connected to the flatbed frame 3.1. Specifically, two supports are welded to the bottom surface of the flatbed frame 3.1, and the two ends of the cylinder rod of the double telescopic pushing cylinder 4.1 are connected to the front and rear supports. Two sets of chain sprocket mechanisms 4.2 are installed on the cylinder barrel of the double telescopic pushing cylinder 4.1. The two sets of chain sprocket mechanisms 4.2 are located at the radial ends of the cylinder barrel, and the two sprockets in the chain sprocket mechanism 4.2 are located at the axial ends of the cylinder barrel.

[0029] The first linear towing assembly is installed with two sets of chain and sprocket mechanisms 4.2 arranged horizontally, and the second linear towing assembly is installed with two sets of chain and sprocket mechanisms 4.2 arranged vertically.

[0030] On the first linear towing assembly, one half-section node of the chain in the two sets of chain sprocket mechanisms 4.2 is connected to the flatbed frame 3.1, and the other half-section node is connected to the sliding trolley 6. When the cylinder of the double telescopic push cylinder 4.1 moves, the stroke of the sliding trolley 6 is equal to the stroke of the cylinder plus half the chain length, that is, the stroke of the sliding trolley 6 is slightly equal to twice the stroke of the cylinder. The chain sprocket mechanism 4.2 amplifies the stroke of the double telescopic push cylinder 4.1, making the overall structure of the transport flatbed 3 more compact.

[0031] On the second linear towing assembly, one half-section node of the chain in the two sets of chain sprocket mechanisms 4.2 is connected to the flatbed frame 3.1, and the other half-section node is connected to the lifting assembly. When the cylinder of the double telescopic push cylinder 4.1 moves, the stroke of the lifting assembly is equal to the stroke of the cylinder plus half the chain length, that is, the stroke of the lifting assembly is slightly equal to twice the stroke of the cylinder. The chain sprocket mechanism 4.2 amplifies the stroke of the double telescopic push cylinder 4.1, making the overall structure of the transport flatbed 3 more compact.

[0032] like Figure 4 As shown, the lifting assembly includes a sliding base, a lifting boom 2.3, and a lifting cylinder 2.2. The sliding base consists of a welded base 2.1 and two rows of pulleys 2.5. The pulleys 2.5 are connected to the welded base 2.1 by bolts. The sliding base is snapped onto the edge of the flatbed frame 3.1. The two rows of pulleys 2.5 are in close contact with the top and bottom surfaces of the flatbed frame 3.1, respectively, to prevent the sliding base from jumping. The welded base 2.1 is connected to the second linear towing assembly by bolts. The chain connection on the component, the top of the welding base 2.1 is hinged to the lifting arm 2.3 by a pin, the welding base 2.1 is hinged to one end of the lifting cylinder 2.2 by a pin, the other end of the lifting cylinder 2.2 is hinged to the lifting arm 2.3 by a pin, the lifting arm 2.3 in the two sets of lifting components is hinged to the same battery lifting device 2.4 by a pin; the top of the welding base 2.1 in the two sets of lifting components is connected by a crossbeam 2.6 between the tops of the welding base 2.1 and between the lifting arms 2.3.

[0033] A rotating support is also installed on the top of the battery hoist 2.4. The rotating support is hinged to the hoisting arm 2.3. The rotating support has a built-in drive motor, and the output shaft of the drive motor is connected to the battery hoist 2.4. When the battery 5 is not in the correct position, the rotating support drives the battery hoist 2.4 to rotate until it is aligned with the battery 5. After the battery 5 is off the ground, the rotating support drives the battery hoist 2.4 to rotate again until the battery 5 is aligned with the transport flatbed 3.

[0034] The left and right sliding bases restrain each other to maintain stability. The two ends of the flatbed frame 3.1 are equipped with limiting structures to block the sliding bases and prevent the hoisting system from falling off the flatbed frame.

The side of the transport flatbed 3 connected to the traction system 1 is the front of the vehicle, and the lifting cylinder 3.2 is located at the rear of the transport flatbed 3.

[0036] When replacing batteries underground, the shovel-type battery quick-change vehicle is positioned in a suitable location under the traction system. Then, the lifting cylinder 3.2 lifts the transport trolley 3, ensuring the vehicle body is stable and the wheels are completely off the ground. Next, the double telescopic push cylinder 4.1 extends and retracts, driving the sprocket and chain to rotate, thereby pulling the hoisting system 2 and the sliding trolley 6 to slide on the trolley frame 3.1 to a suitable position. Finally, the lifting cylinder 2.2 lowers the hoisting arm 2.3, allowing the wire rope on the battery lifting device 2.4 to... The hook can secure the battery. The lifting cylinder 2.2 slowly raises the lifting arm 2.3, raising the battery to a suitable position. The double telescopic push cylinder 4.1 pushes the lifting system 2 to slide horizontally, and then the battery is slowly lowered onto the sliding trolley 6. The double telescopic push cylinder 4.1 pulls the sliding trolley 6 to park the battery in a suitable position on the flatbed frame 3.1. Then the lifting cylinder 3.2 is retracted, and the tires of the shovel-type battery quick-change vehicle slowly touch the ground, thus completing one loading of the battery.
