Description

Technical Field

[0001] The present invention relates to the technical field of new energy shunting locomotives, and particularly relates to a power battery quick replacement system for new energy shunting locomotives. Background Art

[0002] During the process of transforming a shunting locomotive with an internal combustion engine into a new energy shunting locomotive, it is necessary to replace the diesel engine with a power battery, and the power battery supplies power to the AC traction motor. To meet the operating conditions of the new energy shunting locomotive, it is necessary to configure a ground charging facility to charge and replenish the energy of the new energy shunting locomotive. For the application condition where there are a large number of new energy shunting locomotives in centralized operation and on-site real-time charging is unavailable, it is necessary to be equipped with a power battery pack. When the power battery on the new energy shunting locomotive is insufficient in power, a quick replacement system is used for quick replacement, and the spare power battery pack is quickly installed on the new energy shunting locomotive to maintain the operation of the locomotive. The power battery replacement systems in the prior art mainly target the power batteries of electric vehicles for replacement. Since there are significant differences between the power battery structures of electric vehicles and those of new energy shunting locomotives, the two are not of reference significance. However, there is relatively little research on the power battery replacement system for new energy shunting locomotives. Therefore, it is necessary to research and develop a power battery quick replacement system for new energy shunting locomotives. Summary of the Invention

[0003] The purpose of the present invention is to provide a power battery quick replacement system for new energy shunting locomotives, which has the effect of quickly replacing the power battery of the new energy shunting locomotive.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A power battery quick replacement system for new energy shunting locomotives includes a frame, a battery storage rack, a displacement adjustment component for adjusting the position of the battery storage rack, a plurality of battery replacement robots, and power batteries. The power battery includes a battery rack, two rows of installation workstations located within the battery rack, and battery standard boxes located at the installation workstations. The battery storage rack is formed with channels corresponding one-to-one to the installation workstations. A first battery replacement workstation and a second battery replacement workstation are provided within the channels. The battery replacement robot includes a pushing mechanism for pushing the battery standard box within the installation workstation to the first battery replacement workstation, a first manipulator for transferring the battery standard box at the first battery replacement workstation to the second battery replacement workstation, and a second manipulator for transferring the battery standard box at the second battery replacement workstation to the first battery replacement workstation.

[0005] By adopting the above technical solution, the power battery structure of the new energy shunting locomotive generally includes a battery rack and a plurality of battery standard boxes. The battery standard boxes are installed in the installation positions inside the battery rack, and each installation position installs one battery standard box. The battery standard boxes are independent of each other and can be separated or connected to the power battery system individually without affecting the normal use of other battery standard boxes.

[0006] When the present invention performs battery swapping for the power battery, the battery standard box inside the battery rack is taken out, and then the fully charged battery standard box inside the battery storage rack is placed into the installation position inside the battery rack to achieve battery swapping. The specific process is as follows:

[0007] After the new energy shunting locomotive that needs battery swapping stops stably, the displacement adjustment component adjusts the movement of the battery storage rack to align the channel on the battery storage rack with the installation position. The pushing mechanism pushes the battery standard box in the installation position to the first battery swapping position. The first manipulator transfers the battery standard box at the first battery swapping position to the second battery swapping position. At the same time, the second manipulator transfers the battery standard box that has been fully charged in advance at the second battery swapping position to the first battery swapping position. During this process, the two battery standard boxes do not come into contact and collide with each other. The pushing mechanism then pushes the battery standard box at the first battery swapping position back to the installation position.

[0008] The further setting of the present invention is that: the first manipulator includes a swing arm rotatably connected to the top of the channel, a first rotation driving member for driving the swing arm to rotate, a first clamping jaw installed on the swing arm, and a second rotation driving member for driving the first clamping jaw to rotate on the swing arm.

[0009] By adopting the above technical solution, the specific process of the first manipulator transferring the battery standard box at the first battery swapping position to the second battery swapping position is as follows: The first clamping jaw clamps the battery standard box at the first battery swapping position. The first rotation driving member drives the swing arm to rotate 180°. During this process, the second rotation driving member drives the first clamping jaw to rotate 180°. The rotated swing arm brings the battery standard box clamped by the first clamping jaw to the second battery swapping position. Since the second rotation driving member drives the first clamping jaw to rotate 180°, the posture of the battery standard box moved into the second battery swapping position is the same as its posture when it was at the first battery swapping position, so as to facilitate the next battery swapping operation after being fully charged.

[0010] The further setting of the present invention is that: the first clamping jaw includes a first top seat, two first clamping plates hinged on both sides of the first top seat, and two first clamping hydraulic cylinders corresponding to the two first clamping plates respectively. The body of the first clamping cylinder is hinged on the first top seat, and the piston rod of the first clamping hydraulic cylinder is hinged to the first clamping plate.

[0011] By adopting the above technical solution, the piston rod of the first clamping hydraulic cylinder expands and contracts, driving the two first clamping plates to approach or move away from each other, so as to clamp or release the battery standard box.

[0012] A further setting of the present invention is that: a rotating shaft is fixed on the first top seat, the rotating shaft is installed on the swing arm through a bearing, the second rotating driving member is installed on the swing arm, and the second rotating driving member is a swing hydraulic cylinder.

[0013] By adopting the above technical solution, a swing hydraulic cylinder is also called a rotary hydraulic cylinder.

[0014] A further setting of the present invention is that: the side wall of the channel is provided with a first opening and a second opening, the first opening is located on the side of the first switching position, and the second opening is located on the side of the second switching position.

[0015] By adopting the above technical solution, during the process of the swing arm swinging from the first switching position towards the second switching position, the battery standard box clamped by the first claw leaves the first switching position from the first opening and enters the second switching position from the second opening. During the process of the swing arm swinging from the second switching position towards the first switching position, the first claw leaves the second switching position from the second opening and enters the first switching position from the first opening.

[0016] A further setting of the present invention is that: the second manipulator includes a second top seat slidably connected in the channel, a main hydraulic cylinder for driving the second top seat to slide, two side plates fixed on both sides of the second top seat, two second clamping hydraulic cylinders respectively installed on the two side plates, and second clamping plates fixed on the piston rods of the second clamping hydraulic cylinders.

[0017] By adopting the above technical solution, the specific process of the second manipulator transferring the battery standard box pre-charged at the second switching position to the first switching position is as follows: the second clamping hydraulic cylinder drives the two second clamping plates to approach, the two second clamping plates clamp the battery standard box, and the main hydraulic cylinder drives the second top seat to move, driving the battery standard box to move from the second switching position to the first switching position.

[0018] A further setting of the present invention is that: a guide post is fixed on the second clamping plate, the guide post is horizontally arranged, a guide hole is provided on the side plate, and the guide post passes through the guide hole.

[0019] A further setting of the present invention is that: the pushing mechanism includes a pushing frame, a linear motor for driving the pushing frame to move, and a locking component for locking or unlocking the position of the pushing frame. The pushing frame includes a bottom plate and two baffles located at the front and rear ends of the bottom plate. The locking component includes an electric push rod fixed on the battery rack, and the bottom plate is provided with a locking hole for inserting the rod part of the electric push rod.

[0020] By adopting the above technical solution, the battery standard box is located inside the pushing frame, and two baffles are distributed at the front end and the rear end of the battery standard box. When the pushing frame is located inside the installation station, the rod part of the electric push rod is inserted into the locking hole to lock the position of the bottom plate.

[0021] The specific process of the pushing mechanism pushing the battery standard box inside the installation station to the first battery replacement station is as follows: the rod part of the electric push rod disengages from the locking hole, and the linear motor drives the pushing frame to move until the battery standard box inside the pushing frame moves to the first battery replacement station.

[0022] A further setting of the present invention is that: the displacement adjustment assembly includes a lifting seat slidably connected to the frame in the vertical direction, a lifting drive assembly for driving the lifting seat to lift and lower, a first horizontal moving seat slidably connected to the lifting seat in the horizontal direction, a first horizontal drive assembly for driving the first horizontal moving seat to slide on the lifting seat, a second horizontal moving seat slidably connected to the first horizontal moving seat in the horizontal direction, a second horizontal drive assembly for driving the second horizontal moving seat to slide, and the battery storage rack is fixedly installed on the second horizontal moving seat.

[0023] The beneficial effect of the present invention is that: the present invention transfers the battery standard box with depleted power in the power battery to the first battery replacement station through the pushing mechanism, transfers the battery standard box at the first battery replacement station to the second battery replacement station through the first manipulator, and at the same time transfers the battery standard box at the second battery replacement station to the first battery replacement station through the second manipulator, and then the pushing mechanism transfers the fully charged battery standard box at the first battery replacement station to the installation station of the power battery, completing efficient and rapid battery replacement.

The output shaft of the second motor 361 is connected to the second lead screw 362 through a coupling. The second nut assembly is fixed to the second horizontal moving seat 35.

[0035] The power battery 5 is installed and fixed on the new energy shunting locomotive. The power battery 5 includes a battery rack 51, two rows of installation stations 52 located inside the battery rack 51, and battery standard boxes 6 installed in the installation stations 52. Each row of installation stations 52 includes six installation stations 52 distributed in the vertical direction. The entire power battery 5 includes twelve installation stations 52. A first connector is provided in the installation station 52, and a second connector is installed on the battery standard box 6. The second connector is in contact with the first connector.

[0036] Twelve channels 21 are provided on the battery storage rack 2, and the twelve channels 21 respectively correspond to the twelve installation stations 52. A first installation station 52 and a second installation station 52 are formed in each channel 21. A first opening 24 and a second opening 25 are formed on the side wall of each channel 21. The first opening 24 is located on the side of the first installation station 52, and the second opening 25 is located on the side of the second installation station 52. The power battery 5 quick battery replacement system for the new energy shunting locomotive further includes a battery replacement robot 4. The number of battery replacement robots 4 is twelve, which respectively correspond to the twelve channels 21 and the twelve installation stations 52. The battery replacement robot 4 includes a pushing mechanism 43 for pushing the battery standard box 6 in the installation station 52 to the first battery replacement position 22, a first manipulator 41 for transferring the battery standard box 6 at the first battery replacement position 22 to the second battery replacement position 23, and a second manipulator 42 for transferring the battery standard box 6 at the second battery replacement position 23 to the first battery replacement position 22.

[0037] The first manipulator 41 includes a swing arm 413 rotatably connected to the top of the channel 21, a first rotary drive member 411 for driving the swing arm 413 to rotate, a first jaw 414 mounted on the swing arm 413, and a second rotary drive member 412 for driving the first jaw 414 to rotate on the swing arm 413. The first jaw 414 includes a first top seat 4141, two first clamping plates 4142 hinged on both sides of the first top seat 4141, and two first clamping hydraulic cylinders corresponding to the two first clamping plates 4142 respectively. The body of the first clamping cylinder is hinged on the first top seat 4141, and the piston rod of the first clamping hydraulic cylinder is hinged to the first clamping plate 4142. A rotating shaft is fixed to the first top seat 4141, the rotating shaft is installed on the swing arm 413 through a bearing, the second rotary drive member 412 is installed on the swing arm 413, and both the first rotary drive member 411 and the second rotary drive member 412 are rotary hydraulic cylinders.

[0038] Working principle of the first manipulator 41: The specific process of the first manipulator 41 transferring the battery standard box 6 at the first battery changing station 22 to the second battery changing station 23 is as follows: The first jaw 414 clamps the battery standard box 6 at the first battery changing station 22, and the first rotary drive member 411 drives the swing arm 413 to rotate 180°. During this process, the second rotary drive member 412 drives the first jaw 414 to rotate 180°. The rotated swing arm 413 brings the battery standard box 6 clamped by the first jaw 414 to the second battery changing station 23. Since the second rotary drive member 412 drives the first jaw 414 to rotate 180°, the posture of the battery standard box 6 moved into the second battery changing station 23 is the same as its posture at the first battery changing station 22. It should be noted that when the first manipulator 41 drives the battery standard box 6 to leave the first battery changing station 22, the second rotary drive member 412 can adjust the posture of the battery standard box 6 as needed. Considering the gap between the battery standard box 6 and the two baffles 4312, it can smoothly disengage from the pushing frame 431 at the first battery changing station 22.

[0039] The second manipulator 42 includes a second top seat 421 slidably connected in the channel 21, a main hydraulic cylinder 426 for driving the second top seat 421 to slide, two side plates 422 fixed on both sides of the top seat, two second clamping hydraulic cylinders 423 respectively installed on the two side plates 422, and a second clamping plate 424 fixed to the piston rod of the second clamping hydraulic cylinder 423. A guide post 425 is fixed to the second clamping plate 424. The guide post 425 is horizontally arranged, and the side plate 422 is provided with a guide hole through which the guide post 425 passes. A guide rail 211 is fixed in the channel 21, and a slider 427 is fixed to the second top seat 421. The slider 427 is slidably connected to the guide rail 211.

[0040] Working principle of the second manipulator 42: The specific process of the second manipulator 42 transferring the battery standard box 6 that has been pre-charged at the second battery-changing station 23 to the first battery-changing station 22 is as follows: The second clamping hydraulic cylinder 423 drives two second clamping plates 424 to approach each other, and the two second clamping plates 424 clamp the battery standard box 6. The main hydraulic cylinder 426 drives the second top seat 421 to move, driving the battery standard box 6 to move from the second battery-changing station 23 to the first battery-changing station 22. After the battery standard box 6 is directly above the bottom plate 4311, the second manipulator 42 releases the battery standard box 6, and the battery standard box 6 drops onto the bottom plate 4311.

[0041] The pushing mechanism 43 includes a pushing frame 431, a linear motor for driving the pushing frame 431 to move, and a locking assembly for locking or unlocking the position of the pushing frame 431. The pushing frame 431 includes a bottom plate 4311 and two baffle plates 4312 located at the front and rear ends of the bottom plate 4311. The locking assembly includes an electric push rod fixed to the battery rack 51, and the bottom plate 4311 is provided with a locking hole for inserting the rod portion of the electric push rod. A pressing hydraulic cylinder 432 is installed on one of the baffle plates 4312. When the battery standard box 6 is located on the bottom plate 4311, after the piston rod of the pressing hydraulic cylinder 432 extends, it presses the battery standard box 6 against the other baffle plate 4312 to achieve fixation. When the piston rod of the pressing hydraulic cylinder 432 retracts, there is a gap between the battery standard box 6 and the two baffle plates 4312.

[0042] Working principle of the pushing mechanism 43: The specific process of the pushing mechanism 43 pushing the battery standard box 6 in the installation station 52 to the first battery-changing station 22 is as follows: The rod portion of the electric push rod disengages from the locking hole, and the linear motor drives the pushing frame 431 to move until the battery standard box 6 in the pushing frame moves to the first battery-changing station 22.

[0043] Working principle of the fast battery replacement system for power batteries: In the battery storage rack 2, fully charged standard battery boxes 6 are arranged at the second battery replacement position 23 of each channel 21. When a new energy shunting locomotive needs to replace the battery, the shunting locomotive first stops on one side of the frame 1. There is a hinged cover on the shunting locomotive. The staff opens the cover to expose the power battery 5. The fast battery replacement system for the power battery 5 uses camera and computer vision technology or other technologies to identify the position of the power battery 5, and adjusts the position of the battery storage rack 2 through the displacement adjustment component 3, so that the twelve channels 21 on the battery storage rack 2 are attached to and aligned with the twelve installation positions 52 of the power battery 5. The pushing mechanism 43 pushes the standard battery box 6 in the installation position 52 into the first battery replacement position 22 in the channel 21. The first manipulator 41 clamps and drives the standard battery box 6 to leave the first battery replacement position 22 and move to the second battery replacement position 23; at the same time, the second manipulator 42 clamps and drives the fully charged standard battery box 6 to leave the second battery replacement position 23 and move to the first battery replacement position 22. The second manipulator 42 releases the fully charged standard battery box 6 to place it in the pushing frame 431 at the first battery replacement position 22. The pushing mechanism 43 sends the standard battery box 6 in the pushing frame 431 into the installation position 52 of the battery rack 51, and the first connector contacts the second connector.

[0044] The first manipulator 41 releases the standard battery box 6 and places it at the second battery replacement position 23. The first manipulator 41 leaves the second battery replacement position 23 and moves to the first battery replacement position 22. The second manipulator 42 leaves the first battery replacement position 22 and moves to the second battery replacement position 23, and clamps the standard battery box 6 at the second battery replacement position 23. After the displacement adjustment component adjusts the battery storage rack 2 to move it away from the power battery 5, the staff covers the cover of the new energy locomotive to complete the fast battery replacement.
