[0060] The invention provides a parking anti-slip device with a locking function, which can be equipped with mechanical locking in two positions, namely, after braking and after releasing, to ensure parking safety.

[0061] like Figure 1 As shown, a parking anti-skid device with a locking function includes multiple actuators 1, a hydraulic control system 2 and an electrical system 3. The hydraulic control system 2 is communicatively connected with the electrical system 3. The hydraulic control system 2 is connected to the hydraulic brake cylinders 24 of the multiple actuators 1 through oil pipes. The multiple actuators 1 are arranged between two basic rails 4, and there is a gap between two adjacent actuators 1. The two ends of the actuators 1 are fixedly connected to the bottom of the two basic rails 4 respectively.

[0062] like Figure 2 As shown, the actuator 1 includes a supporting mechanism 5, a braking mechanism 6, a locking mechanism 7 and an indicating mechanism 8. The two ends of the supporting mechanism 5 in the length direction are respectively slidably connected to the rail bottoms of the two basic rails 4. The supporting mechanism 5 is used to support the braking mechanism 6, the locking mechanism 7 and the indicating mechanism 8, and adaptively adjust the position of the braking mechanism 6 during braking.

[0063] like Figure 3 As shown, for example, the support mechanism 5 includes a support beam 9, a support frame 10 and an insulating fixing member 11, wherein the support beam 9 is arranged below the two basic rails 4, the support beam 9 and the two basic rails 4 are perpendicular to each other, two support frames 10 are arranged, and the upper part of each support frame 10 is detachably connected to the bottom of a basic rail 4.

[0064] A through slot is disposed at the bottom of each support frame 10, and an insulating fixing member 11 is disposed at the through slot of each support frame 10.

[0065] As Figure 4 and Figure 5 shown, for example, the insulating fixing member 11 includes an insulating limit plate 15 and an insulating clamping plate 16. The slider 14 is square, and the cross-sectional area of the slider 14 is smaller than the cross-sectional area of the end of the support frame 10. The insulating limit plate 15 is arranged on the side of the support frame 10 close to the support beam 9. A first through hole 17 matching the slider 14 is arranged in the middle of the insulating limit plate 15. Two insulating clamping plates 16 are provided, and a U-shaped clamping groove 18 is arranged on each insulating clamping plate 16. The two insulating clamping plates 16 are both arranged on the side of the support frame 10 far from the support beam 9. The U-shaped clamping grooves 18 of the two insulating clamping plates 16 form a square sliding cavity matching the slider 14. The slider 14 slides in the sliding cavity and the first through hole 17. The insulating limit plate 15 and the insulating clamping plate 16 are detachably connected to the support frame 10 by bolts.

[0066] As Figure 3 , Figure 4 and Figure 5 shown, for example, the support mechanism 5 further includes a hook bolt 12. A clamping groove 19 for clamping the bottom of the basic rail 4 is arranged on the upper part of the support frame 10. The clamping groove 19 is clamped with the side of the bottom of the basic rail 4 far from the support beam 9. A second through hole is arranged below the clamping groove 19 of the support frame 10. The threaded section of one end of the hook bolt 12 passes through the second through hole and is connected with a nut. The hook structure at the other end of the hook bolt 12 is clamped with the side of the bottom of the basic rail 4 close to the support beam 9. The support frame 10 is clamped with the basic rail 4 by the hook bolt 12, which is convenient for installation and disassembly.

[0067] As Figure 2 and Figure 6 shown, for example, the braking mechanism 6 is located above the support mechanism 5. The braking mechanism 6 is hinged to the support mechanism 5.

[0068] Among them, the connecting frame 23 is fixedly connected to the left brake frame 25, the piston rod 29 of the brake cylinder 24 is transmission-connected to the left brake frame 25 through the connecting frame 23, the cylinder body 30 of the brake cylinder 24 is fixedly connected to the right brake frame 26, one end of the telescopic assembly 27 is fixedly connected to the upper part of the right brake frame 26, the other end of the telescopic assembly 27 is fixedly connected to the upper part of the guide rail support frame 28, the lower part of the right brake frame 26 is slidingly connected to the lower part of the guide rail support frame 28, and the upper part of the left brake frame 25 and the upper part of the guide rail support frame 28 are both provided with brake rails 20, and the brake rails 20 are parallel to the basic rails 4.

[0069] Both sides of the left brake frame 25 are hinged to one end of the two first crank arms 21 through pins, and the other ends of the two first crank arms 21 are hinged to the support beam 9 through pins. Both sides of the right brake frame 26 are hinged to one end of the two second crank arms 22 through pins, and the other ends of the two second crank arms 22 are hinged to the support beam 9 through pins.

[0070] When the piston rod 29 of the brake cylinder 24 is extended, the left brake frame 25 is rotated and lifted with the first crank arm 21 as a fulcrum, and the right brake frame 26 is rotated and lifted with the second crank arm 22 as a fulcrum, and the brake rail 20 approaches the basic rail 4; when the piston rod 29 of the brake cylinder 24 is retracted, the left brake frame 25 is rotated and lowered with the first crank arm 21 as a fulcrum, and the right brake frame 26 is rotated and lowered with the second crank arm 22 as a fulcrum, and the brake rail 20 moves away from the basic rail 4.

[0071] The locking mechanism 7 is located below the braking mechanism 6 and is fixedly connected to the supporting mechanism 5 . The locking mechanism 7 is used to lock the braking mechanism 6 at a release terminal position or a braking terminal position.

[0072] like Figure 7 , Figure 8 and Fig.10 As shown, for example, the locking mechanism 7 includes a first contact seat 31, a second contact seat 32, a connecting rod 33, a first drive fork 34 and a second drive fork 35. The first contact seat 31 is located below the left brake frame 25, and the bottom of the first contact seat 31 is fixedly connected to the support beam 9. The second contact seat 32 is located below the right brake frame 26, and the bottom of the second contact seat 32 is fixedly connected to the support beam 9.

[0073] The first drive fork 34 is located between the left brake frame 25 and the first contact seat 31. The bottom of the first drive fork 34 is slidably connected to the first contact seat 31 and slides along the extension and retraction direction of the piston rod 29 of the brake cylinder 24. The connecting frame 23 has a cavity 36. A connecting block 38 is provided on the top of the first drive fork 34. The top of the connecting block 38 extends into the cavity 36. The top of the connecting block 38 is fixedly connected to the end of the piston rod 29 of the brake cylinder 24 close to the left brake frame 25 through a limiting nut 37. The first contact seat 31 is provided with a first locking structure for locking the position of the first drive fork 34.

[0074] The second driving fork 35 is located between the right brake frame 26 and the second contact seat 32. The second driving fork 35 is slidably connected to the second contact seat 32 and slides along the extension and retraction direction of the piston rod 29 of the brake cylinder 24. One end of the connecting rod 33 is hinged to the first driving fork 34, and the other end of the connecting rod 33 is hinged to the second driving fork 35. The second contact seat 32 is provided with a second locking structure for locking the position of the second driving fork 35.

[0075] The first locking structure and the second locking structure are used to lock the braking mechanism 6 at the release terminal position or the braking terminal position.

[0076] For example, an adjusting nut 39 is provided on the connecting rod 33 , and the distance between the first driving fork 34 and the second driving fork 35 can be adjusted by adjusting the nut 39 , so as to adaptively adjust the locking position.

[0077] The piston rod 29 of the brake cylinder 24 extends out to drive the connecting block 38 to move toward the left brake frame 25, and the connecting block 38 drives the first drive fork 34 to slide along the first contact seat 31 toward the left brake frame 25. The first drive fork 34 drives the second drive fork 35 to move along the second contact seat 32 toward the left brake frame 25 through the connecting rod 33, and the first locking structure and the second locking structure release the lock of the first drive fork 34 and the second drive fork 35, and the brake mechanism 6 is unlocked from the release terminal position. When the piston rod 29 of the brake cylinder 24 moves for a distance and then contacts the left brake frame 25, it pushes the left brake frame 25 to rotate and lift. When the brake mechanism 6 is at the brake terminal position, the first locking structure and the second locking structure lock the positions of the first drive fork 34 and the second drive fork 35.

[0078] The piston rod 29 of the brake cylinder 24 retracts, driving the connecting block 38 to move away from the left brake frame 25, and the connecting block 38 drives the first driving fork 34 to slide along the first contact seat 31 away from the left brake frame 25. The first driving fork 34 drives the second driving fork 35 to move along the second contact seat 32 away from the left brake frame 25 through the connecting rod 33. The first locking structure and the second locking structure release the lock of the first driving fork 34 and the second driving fork 35. After the piston rod 29 of the brake cylinder 24 moves laterally in the cavity 36 for a distance, when the connecting block 38 contacts the side wall of the cavity 36 of the connecting frame 23 away from the left brake frame 25, the connecting frame 23 is driven to drive the left brake frame 25 to rotate and descend. When the brake mechanism 6 is in the release terminal position, the first locking structure and the second locking structure lock the positions of the first driving fork 34 and the second driving fork 35.

[0079] For example, a first notch 40 is vertically provided on the first side surface of the first driving fork 34 at an end away from the connecting rod 33, and a first locking groove 41 is vertically provided on the second side surface of the first driving fork 34 at a middle position, wherein the first side surface and the second side surface of the first driving fork 34 are parallel and perpendicular to the brake rail 20.

[0080] The first locking structure includes a first locking block 42 and a second locking block 43. The first contact seat 31 is provided with a first fixed seat 44 on the outer side of the first side of the first driving fork 34.

[0108] Among them, the sensor mounting plate 90 is detachably connected to the connecting frame 23 by bolts, and a first proximity sensor 92 and a second proximity sensor 93 are arranged on the sensor mounting plate 90. The first proximity sensor 92 is arranged close to the connecting frame 23, and there is a gap between the first proximity sensor 92 and the second proximity sensor 93 in the moving direction of the piston rod 29 of the brake cylinder 24. The sensor mounting plate 90 is provided with a connecting portion 94 below the first proximity sensor 92 and the second proximity sensor 93, and a second slide groove 95 is arranged on the connecting portion 94.

The position rod 91 is respectively provided with a first detection block 96 and a second detection block 97 on both sides of the connecting part 94.

[0110] like Fig.18 As shown, when the piston rod 29 of the brake cylinder 24 is retracted and the brake rail 20 is located at the release terminal position, the distance between the first detection block 96 and the first proximity sensor 92 is greater than the sensing distance, the first proximity sensor 92 is disconnected, and the second detection block 97 is located directly below the second proximity sensor 93, and the second proximity sensor 93 is connected.

[0111] like Fig.19 As shown, when the piston rod 29 of the brake cylinder 24 is extended and the brake rail 20 is located at the brake terminal position, the first detection block 96 is located directly below the first proximity sensor 92, the first proximity sensor 92 is turned on, the distance between the second detection block 97 and the second proximity sensor 93 is greater than the sensing distance, and the second proximity sensor 93 is turned off.

[0112] The first proximity sensor 92 and the second proximity sensor 93 detect the movement distance of the piston rod 29 of the brake cylinder 24 , thereby determining the terminal position of the actuator 1 .

[0113] like Fig. 22 and Fig.23 As shown, a third proximity sensor 98 is provided on the side of the first fixed seat 44 away from the connecting rod 33, a fourth proximity sensor 99 is provided on the side of the second fixed seat 46 close to the connecting rod 33, a fifth proximity sensor 100 is provided on the side of the third fixed seat 52 close to the connecting rod 33, and a sixth proximity sensor 101 is provided on the side of the fourth fixed seat 54 close to the connecting rod 33.

The first proximity sensor 92 and the second proximity sensor 93 can be arranged on the nodes on both sides of a single device or at the central node. The number of proximity sensors depends on on-site requirements.

[0115] The piston rod 29 of the brake cylinder 24 drives the first drive fork 34 and the second drive fork 35 to move, thereby driving the retraction and extension of each locking block, and the terminal position of each locking block is detected by the proximity sensor to determine whether each actuator 1 is converted to the specified terminal position.

[0116] The mechanical transmission principle of the parking anti-slip device with locking function of the present invention is as follows:

[0117] like Fig.21 As shown, during braking, the piston rod 29 and cylinder body 30 of the brake cylinder 24 are driven to extend, and the left brake frame 25 and the right brake frame 26 are respectively rotated and lifted with the first crank arm 21 and the second crank arm 22 as fulcrums. The right brake frame 26 drives the guide rail support frame 28 to move and then drives the brake rail 20 to press against the wheelset. The first slide groove 80 of the guide rail support frame 28 is slidably connected with the linear guide rail 79 of the right brake frame 26. The right brake frame 26 is telescoped along the guide rail support. Through the joint action of the brake cylinder 24 and the telescopic assembly 27, the positive pressure between the brake rail 20 and the inner side of the wheel rim is maintained. The support beam 9 is adaptively adjusted on the sliding of the support frame 10 through the slider 14. The stop iron 13 can limit the first crank arm 21 and the second crank arm 22. When switching from the braking terminal position to the relief terminal position, the action is opposite, such as Fig. 20 shown.

[0118] During braking, the brake rail 20 acts on the inner side of the wheel rim of the vehicle to achieve the purpose of stopping the vehicle and preventing it from slipping; during release, the brake rail 20 leaves the inner side of the wheel rim of the vehicle and falls down, losing its effect on the vehicle, ensuring the safe passage of the vehicle.

[0119] The locking principle of the parking anti-slip device with locking function of the present invention is as follows:

[0120] like Fig.11As shown, when the parking anti-slip device is in the release terminal position, the first locking block 42 is pushed into the first slot 40 by the first spring 45, and the second locking block 43 is located outside the first locking slot 41, compressed by the second side of the first driving fork 34, and retracted into the second fixed seat 46; the third locking block 50 is pushed into the second locking slot 48 by the third spring 53, and the fourth locking block 51 is located outside the second slot 49, compressed by the second side of the second driving fork 35, and retracted into the third fixed seat 52. The positions of the first driving fork 34 and the second driving fork 35 are locked by the first locking block 42 and the third locking block 50. At this time, the braking mechanism 6 is locked in the release terminal position by the fourth locking block 51. When the third proximity sensor 98 and the fifth proximity sensor 100 are both turned on, and the fourth proximity sensor 99 and the sixth proximity sensor 101 are both turned off, it indicates that the parking anti-slip device is in the braking terminal position.

[0121] like Figure 8 , Fig.12 and Fig. 20 As shown, when the parking anti-skid device is converted from the release terminal position to the brake terminal position, the piston rod 29 of the brake cylinder 24 extends out, and drives the first driving fork 34 to move along the first contact seat 31 toward the left brake frame 25 through the connecting block 38, and the first locking groove 41 on the first driving fork 34 approaches the second locking block 43, and the first locking block 42 slides out from the first notch 40 on the first driving fork 34; the first driving fork 34 drives the second driving fork 35 to move along the second contact seat 32 toward the left brake frame 25 through the connecting rod 33, and the third locking block 50 slides out from the second locking groove 48 on the second driving fork 35, and the second locking block 50 on the second driving fork 35 slides out from the second locking groove 48 on the second driving fork 35. The slot 49 approaches the fourth locking block 51, and then unlocks the brake mechanism 6 from the release terminal position. After the unlocking is completed, the third proximity sensor 98, the fourth proximity sensor 99, the fifth proximity sensor 100 and the sixth proximity sensor 101 are all connected, and the release position indicates disconnection; after the piston rod 29 of the brake cylinder 24 moves laterally for a distance (the distance between the connecting block 38 and the cavity 36 away from the side wall of the left brake frame 25), when the connecting block 38 and the cavity 36 of the connecting frame 23 are close to the side wall of the left brake frame 25, the connecting frame 23 is pushed to move, and the brake mechanism 6 is driven as a whole to move, and at this time, it is converted from the release terminal position to the brake terminal position.

[0122] like Fig.13As shown, when the parking anti-slip device reaches the braking terminal position, the first locking block 42 is located outside the first notch 40, compressed by the first side of the first driving fork 34, and retracted into the first fixed seat 44, and the second locking block 43 is pushed out to the inside of the first locking groove 41 by the second spring 47; the third locking block 50 is located outside the second locking groove 48, compressed by the first side of the second driving fork 35, and retracted into the third fixed seat 52, the fourth locking block 51 is located inside the second notch 49, and the fourth locking block 51 is pushed out to the inside of the second notch 49 by the fourth spring 55, the positions of the first driving fork 34 and the second driving fork 35 are locked by the second locking block 43 and the fourth locking block 51, and the braking mechanism 6 is locked in the braking terminal position by the second locking block 43, and the fourth proximity sensor 99 and the sixth proximity sensor 101 are both turned on, and the third proximity sensor 98 and the fifth proximity sensor 100 are both turned off, indicating that the parking anti-slip device is at the relief terminal position, and the entire conversion process is completed at this time.

[0123] like Figure 8 As shown, when the braking terminal position is converted to the releasing terminal position, the action is opposite, specifically: the piston rod 29 of the brake cylinder 24 retracts to drive the connecting block 38 to move away from the left brake frame 25, and the connecting block 38 drives the first driving fork 34 to slide along the first contact seat 31 away from the left brake frame 25, and the first driving fork 34 drives the second driving fork 35 to move along the second contact seat 32 away from the left brake frame 25 through the connecting rod 33, and the second locking block 43 on the first driving fork 34 slides out of the first locking groove 41, and the first notch 40 on the first driving fork 34 moves toward the first locking block 42; the first driving fork 34 drives the second driving fork 35 to move along the second contact seat 32 away from the left brake frame 25 through the connecting rod 33, and the second driving fork 35 on the second driving fork 35 moves toward the first locking block 42. The second locking groove 48 moves toward the direction approaching the third locking block 50, and the second notch 49 on the second driving fork 35 moves toward the direction away from the fourth locking block 51, thereby unlocking the brake mechanism 6 from the brake terminal position. After unlocking, the third proximity sensor 98, the fourth proximity sensor 99, the fifth proximity sensor 100 and the sixth proximity sensor 101 are all connected, and the brake position indicates disconnection; after the piston rod 29 of the brake cylinder 24 moves laterally for a distance (the distance between the connecting block 38 and the side wall of the cavity 36 away from the left brake frame 25), when the connecting block 38 contacts the side wall of the cavity 36 of the connecting frame 23 away from the left brake frame 25, the connecting frame 23 is pushed to move, and the brake mechanism 6 is driven as a whole to move, and at this time, it is converted from the brake terminal position to the relief terminal position.

[0124] During the overall action of the actuator 1 of the present invention, the locking mechanism 7 can be released first, thereby disconnecting the normal position indication, and then the actuator 1 can be driven to act.

[0125] The principle of the indicating mechanism 8 of the parking anti-slip device with locking function of the present invention indicating the terminal position of the actuator 1 is as follows:

[0126] As shown in Table 1 and Fig. 22 As shown, when the second proximity sensor 93, the fourth proximity sensor 99, and the sixth proximity sensor 101 are all turned on, and the first proximity sensor 92, the third proximity sensor 98, and the fifth proximity sensor 101 are all turned off, it is determined that the parking anti-slip device is located at the relief terminal position.

[0127] As shown in Table 1 and Fig.23 As shown, when the first proximity sensor 92, the third proximity sensor 98, and the fifth proximity sensor 100 are all turned on, and the second proximity sensor 93, the fourth proximity sensor 99, and the sixth proximity sensor 101 are all turned off, it is determined that the parking anti-skid device is located at the braking terminal position.

[0128] When the first proximity sensor 92 , the second proximity sensor 93 , the third proximity sensor 98 , the fourth proximity sensor 99 , the fifth proximity sensor 100 , and the sixth proximity sensor 101 are all disconnected, it is determined that the parking anti-slip device is located in the driving position.
