The two sliding rods 59 are provided with teeth. The two sliding rods 59 are respectively meshed with the two No. 2 worm gears 58 through the teeth. When the two No. 2 worm gears 58 rotate, the two sliding rods 59 are driven by the teeth on the two sliding rods 59 to reciprocate up and down. Since the rotation directions of the two No. 2 worm gears 58 are opposite, the movement directions of the two sliding rods 59 are opposite. When one of the sliding rods 59 moves upward, the other sliding rod 59 moves downward. The two ends of the collector 42 are respectively connected to the box body 511. The two boxes 5 Conductive grease is filled inside 11, a plurality of flat openings 512 are arranged on the box body 511, a plurality of conductive strips are arranged inside the busbar group 41, the collector 42 is slidably connected to the plurality of conductive strips of the busbar group 41 through a plurality of conductors, both box bodies 511 are slidably connected to the busbar group 41, a plurality of flat openings 512 are respectively in contact with the plurality of conductive strips of the busbar group 41, an inner slider 513 is slidably connected inside the box body 511, a push rod 510 is connected to the sliding rod 59, the inner slider 513 is connected to one end of the push rod 510 away from the sliding rod 59, the push rod 510 is slidably connected to the inner wall of the box body 511, when the slide plate 51 slides from the back to the front, the sliding rod 59 at the front moves upward, and the sliding rod 59 at the rear moves downward,The sliding rod 59 at the front lifts the inner slider 513 in the box body 511 at the front through the push rod 510, so that the conductive grease inside the box body 511 at the front is squeezed onto the multiple conductive strips of the busbar group 41 through the multiple flat openings 512. After the conductive grease is applied to the conductive strips, the friction between the carbon brush and the conductive strip can be reduced. When the carbon brush slides over the conductive strips coated with the conductive grease, the multiple flat openings 512 on the box body 511 at the rear shovel the conductive grease on the multiple conductive strips back into the flat openings 512. At the same time, the sliding rod 59 at the rear The inner slider 513 in the box body 511 at the rear is driven to move downward by the push rod 510, so that the box body 511 at the rear can suck the conductive grease contacted by the plurality of flat openings 512 back to the box body 511 through the negative pressure. The box body 511 is internally rotatably installed with a plurality of ball cylinders 515, and the ball cylinders 515 are connected with a plurality of stirring rods 516. The inner slider 513 is installed with a plurality of screw rods 514, and the surface of the screw rods 514 is provided with thread grooves.

The conductive grease is recycled so that the contact position between the busbar group 41 and the collector 42 can always maintain a certain amount of conductive grease. The conductive grease can reduce the friction between the collector 42 and the busbar group 41, thereby reducing the power required for the movement of the frame 2. The application of conductive grease can also play a certain maintenance role on the busbar group 41 and the collector 42, and can also reduce the power loss transmitted from the busbar group 41 to the collector 42. The two boxes 511 greatly reduce the contact between the conductive grease and the air through cooperation, thereby extending the service life of the conductive grease.

[0037] For further information, see Fig. 9 - Fig.11The protective component 6 is used to protect the cable 43. The protective component 6 is arranged at the bottom of the frame 2. The protective component 6 includes a protective cover 61. The protective cover 61 is installed at the bottom of the frame 2. A plurality of hanging blocks 62 are slidably installed at the bottom of the frame 2. The plurality of hanging blocks 62 are connected to the outer wall of the cable 43. A spring is arranged between every two adjacent hanging blocks 62. The elastic force of the springs between the plurality of hanging blocks 62 arranged from left to right increases successively. A pull rope 63 is connected to the hanging block 62 close to the crane 3. One end of the pull rope 63 away from the hanging block 62 is connected to the crane 3. A part of the cable 43 is located inside the protective cover 61. When the crane 3 is not working, the cable 43 is located in the protective cover 61. When the crane 3 is working, the unexpanded part of the cable 43 is located in the protective cover 61. In the embodiment, the protective cover 61 plays a certain protective role on the cable 43 and delays the aging of the cable 43. When the crane 3 slides to the left on the frame 2, the crane 3 pulls a hanging block 62 close to the crane 3 through the pull rope 63. After the hanging block 62 is pulled to the left, multiple hanging blocks 62 slide to the left one by one. During the sliding of multiple hanging blocks 62 to the left, the cable 43 is driven to the left. When the crane 3 moves to the right, the springs between the multiple hanging blocks 62 drive the multiple hanging blocks 62 to reset, so that the cable 43 gradually extends or contracts with the movement of the crane 3, and the power supply to the crane 3 is maintained. Two sliding frames 67 are slidably installed on the inner wall of the protective cover 61, and two pry bars 66 are rotatably installed on the inner wall of the protective cover 61. One end of the two pry bars 66 is connected to the bracket The other ends of the two pry bars 66 are respectively hinged to the bottom of the two sliding frames 67, the cable 43 is located between the two sliding frames 67, and a plurality of cleaning brushes 68 are respectively installed on the two sliding frames 67, and the plurality of cleaning brushes 68 are in contact with the outer wall of the cable 43. A turntable 64 is connected to one end of the rotating shaft 52, and a slide frame 65 is slidably installed on the slide plate 51. The turntable 64 is slidably connected to the inner wall of the slide frame 65 through a roller, and the bottom of the slide frame 65 contacts one of the pry bars 66 during the movement. The two pry bars 66 use the lever principle to lift the two sliding frames 67 upward. When the slide frame 65 moves upward, the two sliding frames 67 are reset downward by their own gravity and drive the two pry bars 66 to reset. When the two sliding frames 67 move, they respectively drive the plurality of cleaning brushes 66 8 synchronous movement, so that when the frame 2 and the crane 3 are working, the multiple cleaning brushes 68 can reciprocate up and down. During the reciprocating movement, the multiple cleaning brushes 68 clean the cable 43 located in the protective cover 61, reducing the accumulation of dirt on the surface of the cable 43, avoiding the accumulation of a lot of dirt on the surface of the cable 43 and corroding the protective layer of the cable 43, affecting the insulation performance of the cable 43, and affecting the smoothness of the current. Through the setting of the protective component 6, the crane 3 can drag the cable 43 through the pull rope 63 and the multiple hanging blocks 62, avoiding directly dragging the cable 43 to increase the wear of the cable 43 and reduce the service life of the cable 43. The protective cover 61 can play a certain protective role on the cable 43 and prolong the aging time of the cable 43;By setting a plurality of cleaning brushes 68, the plurality of cleaning brushes 68 can clean the cable 43 when the crane 3 is working, maintain the cleanliness of the cable 43, ensure the power transmission performance of the cable 43, and further extend the service life of the cable 43; by setting the ball cylinder 515 and the stirring rod 516, the plurality of stirring rods 516 can stir the conductive grease in the box 511 evenly by rotating, so that the texture of the conductive grease is more uniform, and its use effect is promoted, so as to avoid the conductive grease in the upper layer from gradually decreasing in quality after long-term use, while the conductive grease in the lower layer has a low utilization rate. ;

[0038] Further, see Fig.12 The cooling component 7 is used to reduce the temperature generated when the power supply component 4 is working. The cooling component 7 is arranged on the lubricating component 5. The cooling component 7 includes an air bag 72, which is installed on the slide 51. An air pipe 73 is installed on the air bag 72. A water tank 74 is installed on the slide 51. When used in high temperature weather, the staff regularly fills the water tank 74 with water. An atomizing nozzle 75 is installed on the water tank 74. The end of the air pipe 73 away from the air bag 72 is connected to the water tank 74. The outer wall of the rotating shaft 52 is connected to the cam 71. The cam 71 contacts the air bag 72 during movement. When the cam 71 rotates, it will repeatedly squeeze the air bag 72. After the air bag 72 is squeezed, the air is filled into the water tank 74 through the air pipe 73. The water tank 74 is The water is sprayed out through the atomizing nozzle 75 by the pressure effect, and the sprayed water mist can take away part of the heat of the air above the slide plate 51 and the surface of the busbar group 41 through the evaporation and heat absorption effect, thereby reducing the heat of the contact position of the slide plate 51, the collector 42 and the busbar group 41. Through the setting of the cooling component 7, water mist can be continuously generated above the contact position between the collector 42 and the busbar group 41 to take away part of the heat through evaporation, thereby avoiding the situation where the collector 42 and the busbar group 41 generate more heat due to the continuous friction between the collector 42 and the busbar group 41 when used in high temperature weather, causing the collector 42 and the busbar group 41 to overheat when working for a long time, resulting in increased resistance, increased power loss, and reduced energy efficiency of the power supply system.

[0039] With the above structure, the working principle of this case is that the busbar group 41 is connected to the external power supply, the crane 3 slides on the frame 2, the frame 2 slides on the track 1, and the frame 2 drives the slide plate 51 to slide on the busbar group 41 through the bracket when sliding, and the slide plate 51 drives the collector 42 to slide on the busbar group 41 through the bracket. The collector 42 contacts with multiple conductive strips of the busbar group 41 through multiple conductors, so that the collector 42 can collect electricity on the busbar group 41 during sliding, and then transmit the electricity to the frame 2 and the crane 3; the slide plate 51 drives the rotating shaft 52 to move synchronously when sliding, and the rotating shaft 52 drives the gear 54 to move synchronously when rotating. Since the gear 54 is meshed with the rack 53, the gear 54 is in motion. When the gear 54 rotates, it is rotated by the reverse thrust of the rack 53. When the gear 54 rotates, it drives the rotating shaft 52 to rotate. When the rotating shaft 52 rotates, it drives the two worm wheels 56 to rotate through the No. 1 worm 55. The two worm wheels 56 drive the two No. 2 worms 58 to rotate through the two belts 57. The two No. 2 worms 58 drive the two sliding rods 59 to reciprocate up and down through the teeth on the two sliding rods 59. Since the rotation directions of the two No. 2 worms 58 are opposite, the movement directions of the two sliding rods 59 are opposite. When one of the sliding rods 59 moves upward, the other sliding rod 59 moves downward. The interiors of the two boxes 511 are filled with conductive grease. When the slide plate 51 slides from back to front, the sliding rod 59 located in the front moves upward, and the sliding rod 59 located in the front moves upward. The sliding rod 59 at the rear moves downward, and the sliding rod 59 at the front lifts the inner slider 513 in the box body 511 at the front through the push rod 510, so that the conductive grease inside the box body 511 at the front is squeezed onto the multiple conductive strips of the busbar group 41 through the multiple flat openings 512. After the conductive grease is applied to the conductive strips, the friction between the carbon brush and the conductive strip can be reduced. When the carbon brush slides over the conductive strips coated with the conductive grease, the multiple flat openings 512 on the box body 511 at the rear shovel the conductive grease on the multiple conductive strips back into the flat openings 512. At the same time, the sliding rod 59 at the rear drives the inner slider 513 in the box body 511 at the rear to move downward through the push rod 510, so that the conductive grease inside the box body 511 at the front is squeezed onto the multiple conductive strips of the busbar group 41 through the multiple flat openings 512. The box 511 absorbs the conductive grease that the multiple flat openings 512 contact back to the box 511 through the negative pressure. When the slide plate 51 slides from front to back, similar to the above steps, the box 511 at the rear squeezes out the conductive grease, and the box 511 at the front absorbs the conductive grease back. When the inner slider 513 slides up and down in the box 511, the inner slider 513 drives the multiple screw rods 514 to slide up and down. During the sliding process of the multiple screw rods 514, the multiple ball cylinders 515 are driven to rotate through the balls. When the ball cylinders 515 rotate, they drive the multiple stirring rods 516 to rotate. The stirring rods 516 stir the conductive grease in the box 511 through rotation, so that the conductive grease in the box 511 has a more uniform texture.Through the cooperation of the lubrication component 5 and the power supply component 4, one box 511 can apply the conductive grease to the busbar group 41 that is about to contact the current collector 42, and the other box 511 recovers the conductive grease on the busbar group 41 after the current collector 42 slides over, so that the contact position of the busbar group 41 and the current collector 42 can always maintain a certain amount of conductive grease. The conductive grease can reduce the friction between the current collector 42 and the busbar group 41, thereby reducing the power required for the movement of the frame 2. Applying the conductive grease can also play a certain maintenance role for the busbar group 41 and the current collector 42, and can also reduce the power loss transmitted from the busbar group 41 to the current collector 42; through the arrangement of the ball cylinder 515 and the stirring rod 516, the multiple stirring rods 516 can stir the conductive grease in the box 511 evenly by rotating, so that the texture of the conductive grease is more uniform, which promotes its use effect, and avoids the conductive grease in the upper layer from gradually decreasing in quality after long-term use, while the utilization rate of the conductive grease in the lower layer is low. ;

[0040] When the crane 3 slides to the left on the vehicle frame 2, the crane 3 pulls a hanging block 62 close to the crane 3 through the pull rope 63. After the hanging block 62 is pulled to the left, the cable 43 moves to the left. Since the elastic force of the springs between the multiple hanging blocks 62 arranged from left to right increases in sequence, the pull rope 63 keeps pulling the leftmost hanging block 62 to the left. When the left hanging block 62 moves to the left to a certain distance from the right hanging block 62, the left hanging block 62 will drive the right hanging block 62 to move to the left through the spring, and the multiple hanging blocks 62 move to the left one by one. The sliding effect is that the multiple hanging blocks 62 slide to the left and drive the cable 43 to the left. When the crane 3 moves to the right, the springs between the multiple hanging blocks 62 drive the multiple hanging blocks 62 to reset, so that the cable 43 gradually extends or contracts with the movement of the crane 3, and the power supply to the crane 3 is maintained. When the crane 3 is not working, the cables 43 are all located in the protective cover 61. When the crane 3 is working, the unexpanded part of the cable 43 is located in the protective cover 61. The protective cover 61 plays a certain protective role on the cable 43 and delays the aging of the cable 43. The rotating shaft 52 rotates When the pulley turntable 64 rotates, the turntable 64 drives the slide frame 65 to reciprocate up and down through the roller. When the slide frame 65 moves downward, the bottom of the slide frame 65 contacts one end of one of the pry bars 66 and applies downward pressure to it, so that the pry bar 66 rotates around the connection point between the pry bar 66 and the protective cover 61. Since the two pry bars 66 are connected, one pry bar 66 can drive the other pry bar 66 to move synchronously. The two pry bars 66 use the lever principle to lift the two sliding frames 67 upward. When the slide frame 65 moves upward, the two sliding frames 67 is reset downward by its own gravity and drives the two pry bars 66 to reset. When the two sliding frames 67 move, they respectively drive the multiple cleaning brushes 68 to move synchronously, so that when the frame 2 and the crane 3 are working, the multiple cleaning brushes 68 can reciprocate up and down. During the up and down reciprocating movement, the multiple cleaning brushes 68 clean the cable 43 located in the protective cover 61, reduce the accumulation of dirt on the surface of the cable 43, avoid the accumulation of too much dirt on the surface of the cable 43 and corrode the protective layer of the cable 43, affect the insulation performance of the cable 43, and affect the smoothness of the current. By setting the protection component 6, the crane 3 can drag the cable 43 through the pull rope 63 and the multiple hanging blocks 62, avoiding direct dragging of the cable 43 to increase the wear of the cable 43 and reduce the service life of the cable 43. The protective cover 61 can play a certain protective role on the cable 43 and extend the aging time of the cable 43. By setting the multiple cleaning brushes 68, the multiple cleaning brushes 68 can clean the cable 43 when the crane 3 is working, maintain the cleanliness of the cable 43, ensure the power transmission performance of the cable 43, and further extend the service life of the cable 43.

[0041] When used in high temperature weather, the staff regularly fills the water tank 74 with water. When the rotating shaft 52 rotates, it drives the cam 71 to rotate. When the cam 71 rotates, it repeatedly squeezes the airbag 72. After being squeezed, the airbag 72 fills the water tank 74 through the air pipe 73. The water tank 74 sprays water through the atomizing nozzle 75 through the positive pressure. The sprayed water mist can take away part of the heat of the air above the slide plate 51 and the surface of the busbar group 41 through the evaporation and heat absorption effect, thereby reducing the heat of the contact position between the slide plate 51, the collector 42 and the busbar group 41. Through the setting of the cooling component 7, water mist can be continuously generated above the contact position between the collector 42 and the busbar group 41, and part of the heat is taken away through evaporation, so as to avoid the situation that when used in high temperature weather, the collector 42 and the busbar group 41 generate more heat due to continuous friction between the collector 42 and the busbar group 41, which causes the collector 42 and the busbar group 41 to overheat when working for a long time, resulting in increased resistance, increased power loss, and reduced energy efficiency of the power supply system.
