Description

Technical Field

[0001] The invention relates to the technical field of emergency power supply vehicles, and in particular to a grounding body quick removal device for an emergency power supply vehicle. Background Art

[0002] With the development of the new energy vehicle industry, the market share of electric vehicles continues to increase. However, the battery life of electric vehicles is limited. Vehicle failures due to insufficient power often occur. In addition, some special operation vehicles, such as sanitation vehicles, sprinkler trucks, transport trucks, etc., are difficult to find nearby charging stations due to their working environment and duration. In order to solve this problem, emergency power supply vehicles came into being. Emergency power supply vehicles charge electric vehicles through their own energy storage media. When the emergency power supply vehicle charges the power supply vehicle, a reliable grounding device is required for grounding.

[0003] Emergency power supply vehicles usually use grounding devices such as metal grounding piles and ion grounding rods, which are manually driven into deep soil during use. This has the disadvantages of inconvenient transportation and installation, high grounding resistance, short service life, and high cost and maintenance. In order to reduce the grounding resistance to the required limit, the vertical grounding piles of emergency power supply vehicles are often driven 1.5 to 3 meters below the ground during actual use. In some soil conditions with high soil resistivity, the depth will reach several meters, which makes it difficult to manually pull the vertical grounding piles out of the ground during disassembly. On the one hand, it causes the waste of individual grounding bodies and increases costs. On the other hand, there are also problems of personnel injuries and increased labor costs when manually disassembling vertical grounding piles.

[0004] In the prior art, an invention patent with publication number CN114156709A discloses a portable grounding body quick removal device for an emergency power supply vehicle and a method for using the same. The grounding body is locked by a clamping plate. After it is locked, the guide column continues to move upward, driving the grounding body to automatically pull out. However, when the guide column moves downward, the clamping plate loosens and locks the grounding body, and the grounding body falls under its own weight, so that the previously pulled out grounding body needs to be continued to be lifted during the next pull-out, and the same section of the grounding body is repeatedly lifted, which reduces the removal efficiency. Summary of the invention

[0005] In view of this, the present invention proposes a device for quickly removing the grounding body of an emergency power supply vehicle and a method for using the same, so as to solve the technical problem proposed in the above background technology that when the guide column moves downward, the clamping plate loosens and locks the grounding body, and the grounding body falls under the action of its own weight, so that the grounding body pulled up before needs to be continued to be lifted when it is pulled up next time, and the same section of the grounding body is repeatedly lifted, which reduces the removal efficiency.

[0050] Reference Figure 1-10 As shown, the first embodiment of the present invention provides a quick removal device for the grounding body 100 of an emergency power supply vehicle, comprising a base 1, a first clamping assembly 2, a second clamping assembly 3 and a lifting cylinder 4, wherein:

[0051] The base 1 is used to be fixed on the ground;

[0052] The first clamping assembly 2 includes a first clamping seat 21 and a first clamping mechanism 22. The first clamping seat 21 is fixed to the base 1. The first clamping seat 21 can be welded and fixed to the base 1. The first clamping mechanism 22 is installed on the first clamping seat 21 and is used to clamp the grounding body 100.

[0053] The second clamping assembly 3 includes a guide column 31, a second clamping seat 32 and a second clamping mechanism 33.

After the machine base 1 is fixed with a reference, the guide column 31 is parallel to the grounding body 100, and the two guide columns 31 are respectively located at the two ends of the top surface of the second clamping seat 32; the second clamping seat 32 is slidably mounted on the guide column 31 and is located above the first clamping seat 21. The second clamping seat 32 can be fixedly connected to a sliding bearing, and the sliding bearing is slidably mounted on the guide column 31; the second clamping mechanism 33 is mounted on the second clamping seat 32 for clamping the grounding body 100; the second clamping mechanism 33 and the first clamping mechanism 22 alternately clamp the grounding body 100;

[0054] The lifting cylinder 4 is installed on the machine base 1 and connected to the second clamping seat 32, and is used to drive the second clamping seat 32 to perform reciprocating linear motion along the guide column 31. By controlling the stroke of the lifting cylinder 4, when the lifting cylinder 4 drives the second clamping seat 32 to rise to the highest point, it drives the second clamping seat 32 to descend to the initial position.

[0055] The present embodiment proposes a device for quickly removing the grounding body 100 of the emergency power supply vehicle, wherein the grounding body 100 is clamped by the second clamping mechanism 33, and the lifting cylinder 4 drives the second clamping seat 32 to rise to the highest point, and the second clamping mechanism 33 releases the grounding body 100, and the first clamping mechanism 22 clamps the grounding body 100, and the lifting cylinder 4 drives the second clamping mechanism 33 to descend to the initial position, and the above steps are repeated to completely pull out the grounding body 100; during the descent of the second clamping mechanism 33, the grounding body 100 is clamped by the first clamping mechanism 22, so that the grounding body 100 will not fall under the action of its own weight, thereby eliminating the need to repeatedly lift the same section of the grounding body 100, thereby improving the removal efficiency of the grounding body 100.

[0056] In some embodiments, the emergency power supply vehicle grounding body 100 rapid removal device further includes a transmission assembly 5, wherein the transmission assembly 5 is respectively connected to the lifting cylinder 4 and the first clamping mechanism 22, and is used to synchronously drive the first clamping mechanism 22 to move while the lifting cylinder 4 drives the second clamping seat 32 to rise, and when the second clamping seat 32 rises to the highest position, the first clamping mechanism 22 clamps the grounding body 100. By synchronously driving the first clamping mechanism 22 to move while the lifting cylinder 4 drives the second clamping seat 32 to rise, the transmission assembly 5 is used to synchronously drive the first clamping mechanism 22 to move while the second clamping seat 32 rises to the highest position, and the first clamping mechanism 22 clamps the grounding body 100, so that the second clamping seat 32 can be immediately lowered after rising to the highest point, without stopping the movement of the second clamping seat 32, which can save time and improve the removal efficiency of the grounding body 100.

[0057] In some embodiments, the first clamping mechanism 22 includes two driving shafts 221 and two first clamping arms 222, the two driving shafts 221 are rotatably mounted on the first clamping seat 21, and the first clamping arms 222 are mounted on the driving shafts 221;

[0058] The transmission assembly 5 includes two gears 51, a rack 52, a transmission rod 53, a swing rod 54 and a connecting block 55; the two gears 51 are respectively mounted on the two driving shafts 221; the two sides of the rack 52 are respectively meshed with the two gears 51, and the two side surfaces of the rack 52 are provided with meshing teeth, and the rack 52 is located between the two gears 51; the second clamping seat 32 is provided with a positioning block 211 and a limit block 212, the positioning block 211 is provided with a positioning groove 2111, and the inner wall of the positioning groove 2111 is provided with a sliding hole 2112, the limit block 212 is connected to the bottom of the sliding hole 2112 by a spring 213, the transmission rod 53 is connected to the rack 52 and is slidably mounted in the positioning groove 2111, and the side of the transmission rod 53 is provided with a The limit groove 531 matches the positioning block 212. When the limit groove 531 does not move to match the limit block 212, the limit block 212 is compressed in the sliding hole 2112 due to the interference of the transmission rod 53, and does not affect the sliding of the transmission rod 53; a guide groove 11 is provided on the machine base 1, and the guide groove 11 includes an upper limit portion 111, a lower limit portion 112 and an inclined portion 113 connected between the upper limit portion 111 and the lower limit portion 112, and there is a smooth transition between the three. The lower limit portion 112 is close to the first clamping seat 21, and the two ends of the swing rod 54 are respectively hinged to the transmission rod 53 and the connecting block 55. A sliding column 541 is provided in the middle of the swing rod 54, and the sliding column 541 is slidably installed in the guide groove 11; the connecting block 55 is fixedly installed on the output shaft of the lifting cylinder 4.

[0059] In this embodiment, during the rising process of the lifting cylinder 4, the connecting block 55 moves in the vertical direction to drive the sliding column 541 to slide along the guide groove 11. The sliding column 541 moves from the lower limit portion 112 to the upper limit portion 111. After passing through the inclined portion 113, it drives the transmission rod 53 to move along the positioning groove 2111 in the direction away from the gear 51, so that the rack 52 drives the two gears 51 to rotate towards each other, driving the two first clamping arms 222 to clamp the grounding body 100. When the lifting cylinder 4 drives the second clamping seat 32 to rise to the highest point, the sliding column 541 is located at the upper limit portion 111, and the two first clamping arms 222 clamp the grounding body 100. The limit block 212 pops out into the limit groove 531, so that the first clamping arm 222 remains clamped during the descending process of the lifting cylinder 4.

[0060] In some embodiments, a wedge-shaped surface 5311 is provided on the side of the limiting groove 531 close to the rack 52, and a guide surface 2121 matching the wedge-shaped surface 5311 is provided on the limiting block 212; the limiting groove 531 is provided with a limiting surface 5312 on the opposite side of the wedge-shaped surface 5311, and the limiting surface 5312 is used for abutting against the limiting block 212 for limiting. A limiting surface 5312 is provided on the opposite side of the wedge surface 5311 through the limiting groove 531. When the limiting block 212 pops out into the limiting groove 531, the limiting surface 5312 abuts against the limiting block 212 to limit the position, so that the transmission rod 53 and the rack 52 cannot continue to move in the direction away from the gear 51, and the limiting function is activated; when it is necessary to drive the rack 52 to move, the guide surface 2121 of the limiting block 212 slides out along the wedge surface 5311, so that the transmission rod 53 and the rack 52 can move in the direction close to the gear 51, driving the first clamping arm 222 to move in the opposite direction to loosen the grounding body 100.

[0061] In some embodiments, the transmission rod 53 is provided with an idle groove 532 along the moving direction of the rack 52, and a connecting column 542 is provided at one end of the swing rod 54. The connecting column 542 is installed in the idle groove 532. When the second clamping seat 32 is descending, the connecting column 542 slides along the idle groove 532 away from one end of the rack 52 to the other end. During the descent of the lifting cylinder 4, the sliding column 541 moves from the upper limit portion 111 to the lower limit portion 112, and the connecting column 542 slides along the idle groove 532 from one end away from the rack 52 to the other end, and will not push the transmission rod 53 to move, so that during the descent of the lifting cylinder 4, the first clamping arm 222 remains in a clamped state. After reaching the end of the idle groove 532 away from the rack 52, the lifting cylinder 4 continues to descend slightly, which will drive the rack 52 to move, causing the two gears 51 to rotate in the opposite direction, so that the first clamping arm 222 is loosened. During the process of continuing to descend slightly, the second clamping mechanism 33 gradually clamps the grounding body 100, thereby ensuring that the first clamping mechanism 22 and the second clamping mechanism 33 alternately clamp the grounding body 100, so that the grounding body 100 will not fall automatically, thereby improving the removal efficiency.

[0062] In some embodiments, the first clamping arm 222 includes a first connecting rod 2221, a first clamping rod 2222 and a first telescopic cylinder 2223, one end of the first connecting rod 2221 is fixedly connected to the driving shaft 221, the middle part of the first clamping rod 2222 is hinged to the other end of the first connecting rod 2221, one end of the first telescopic cylinder 2223 is hinged to the first connecting rod 2221, and the other end is hinged to one end of the first clamping rod 2222. The drive shaft 221 is driven to rotate by the gear 51, thereby driving the first connecting rod 2221 to rotate together, and the rack 52 drives the two gears 51 to rotate towards each other, thereby driving the two first connecting rods 2221 to move closer to each other, thereby clamping the grounding body 100; in addition, the middle part of the first clamping rod 2222 is driven by the first telescopic cylinder 2223 to rotate around the end of the first connecting rod 2221, thereby embracing the grounding body 100, so that the fixing and clamping effect of the grounding body 100 is better, and the grounding body 100 can be better prevented from falling under the action of its own weight, and the grounding body 100 can be pulled up more efficiently.

[0063] In some embodiments, the second clamping mechanism 33 includes two actuators 331 and two second clamping arms 332. The two actuators 331 are mounted on the second clamping seat 32. The second clamping arms 332 are fixedly connected to the output shaft of the actuator 331 to rotate under the drive of the actuator 331. The two second clamping arms 332 are driven toward each other by the two actuators 331 to clamp the grounding body 100. The two second clamping arms 332 are driven away from each other by the two actuators 331 to release the grounding body 100. The actuator 331 can be a motor, which is uniformly controlled by a controller, and the two actuators 331 act simultaneously.

[0064] In some embodiments, the second clamp arm 332 includes a second connecting rod 3321, a second clamping rod 3322, and a second telescopic cylinder 3323. One end of the second connecting rod 3321 is fixedly connected to the output shaft of the actuator 331, the middle part of the second clamping rod 3322 is hinged to the other end of the second connecting rod 3321, and one end of the second telescopic cylinder 3323 is hinged to the second connecting rod 3321, and the other end is hinged to one end of the second clamping rod 3322. The actuator 331 drives the second connecting rod 3321 to rotate, and the two actuators 331 rotate toward each other, thereby driving the two second connecting rods 3321 to move closer to each other, thereby clamping the grounding body 100; in addition, the second telescopic cylinder 3323 drives the middle part of the second clamping rod 3322 to rotate around the end of the second connecting rod 3321, thereby embracing the grounding body 100, so that the fixed clamping effect of the grounding body 100 is better, and the grounding body 100 can be pulled up more efficiently.

[0065] In some embodiments, the base 1 includes a horizontal portion and a vertical portion perpendicular to each other, the horizontal portion is used to be fixed on the ground, the vertical portion is provided with a hollowed-out groove 12, and the lifting cylinder 4 is installed in the hollowed-out groove 12. The horizontal portion is fixed on the ground, with the grounding body 100 as a reference, so that the guide column 31 and the grounding body 100 are parallel, and the lifting cylinder 4 is placed through the hollowed-out groove 12, which can save space, make the structure more compact, and make the structure more miniaturized and easy to carry.
