Description

[0002] When rail transit vehicles are being overhauled, flaw detection equipment is required to perform flaw detection operations on the wheelsets in the overhaul trench.

[0026] like Figure 1 As shown, a water and electricity docking device described in an embodiment of the present application includes an equipment end component 10, an intermediate switching component 20 and a docking base component 30. For the convenience of description, the spatial rectangular coordinate system shown in the accompanying drawings is introduced to explain the relevant structure of the embodiment of the present application, wherein the direction indicated by the X-axis is the front, the direction indicated by the Y-axis is the right, and the direction indicated by the Z-axis is the top.

[0027] The device-side component 10 is used to be installed on a flaw detection device, such as Figure 2 As shown, it includes a device mounting seat 11, a quick-change mechanism main plate 12, a first electrical connector 13 and a first water pipe connector 14. The device mounting seat 11 is connected to one side of the quick-change mechanism main plate 12, and the device mounting seat 11 is mainly used to connect with the flaw detection equipment. The first electrical connector 13 and the first water pipe connector 14 are connected to the quick-change mechanism main plate 12, for example, the first electrical connector 13 is connected to the top of the quick-change mechanism main plate 12, and is used to connect with the electrical components of the flaw detection equipment; the first water pipe connector 14 is connected to the bottom of the quick-change mechanism main plate 12, and is used to connect with the water system of the flaw detection equipment.

[0028] The intermediate switching assembly 20 is used to connect the drag chain containing power and water sources, such as Figure 3 As shown, it includes a quick-change mechanism sub-disk 21, a drag chain connecting plate 22, a drag chain connecting seat 23, a second electrical connector 24 and a second water pipe connector 25. The drag chain connecting plate 22 is connected to the quick-change mechanism sub-disk 21, such as being connected to the right side of the quick-change mechanism sub-disk 21, and the drag chain connecting seat 23 is installed on the drag chain connecting plate 22, and the drag chain connecting seat 23 is used to connect the drag chain. The second electrical connector 24 and the second water pipe connector 25 are connected to the quick-change mechanism sub-disk 21, wherein the second electrical connector 24 is used to be detachably connected to the first electrical connector 13, and the second water pipe connector 25 is used to be detachably connected to the first water pipe connector 14. Correspondingly, the second electrical connector 24 can be connected to the top of the quick-change mechanism sub-disk 21, and the second water pipe connector 25 can be connected to the bottom of the quick-change mechanism sub-disk 21. The power supply and water source on the drag chain are respectively connected to the second electrical connector 24 and the second water pipe connector 25. One side of the quick-change mechanism sub-disk 21 is used to be detachably connected to the side of the quick-change mechanism main disk 12 away from the device mounting seat 11. The quick-change mechanism main disk 12 and the quick-change mechanism sub-disk 21 together form a quick-change structure to achieve rapid connection and disassembly of the device-end component 10 and the intermediate switching component 20. The quick-change mechanism can adopt a tool quick-change disk of the LTC model produced by Zhengzhou Linghang Robot Co., Ltd.

[0029] The docking base assembly 30 is used to be installed at the end of the maintenance trench, such as Figure 4 As shown, it includes a base 31 and a connecting plate 38, and the connecting plate 38 is connected to the base 31. The connecting plate 38 is detachably connected to the intermediate switching assembly 20.

[0030] In the embodiment of the present application, the device end assembly 10 is installed on the flaw detection equipment, the docking base assembly 30 is installed at the end of the maintenance trench, and the drag chain is connected to the intermediate switching assembly 20. When there is no flaw detection operation, the intermediate switching assembly 20 is connected to the docking base assembly 30. After the rail transit vehicle enters the maintenance trench, the flaw detection equipment with the device end assembly 10 is hoisted into the trench, and then the flaw detection equipment is moved to the docking base assembly 30 at the end of the maintenance trench and connected to the intermediate switching assembly 20 through a quick change mechanism, and then the connection between the intermediate switching assembly 20 and the docking base assembly 30 is disconnected. After the intermediate switching assembly 20 is connected to the device end assembly 10, the second electrical connector 24 is connected to the first electrical connector 13, and the second water pipe connector 25 is connected to the first water pipe connector 14, so that the drag chain supplies power and water to the flaw detection equipment, and then the flaw detection equipment can move freely on the track of the trench and perform flaw detection operations. After the flaw detection operation is completed, the flaw detection equipment moves back to the docking base assembly 30 at the end of the maintenance trench. After the intermediate switching assembly 20 is connected to the docking base assembly 30, the connection between the intermediate switching assembly 20 and the device end assembly 10 is disconnected, and then the flaw detection equipment can be lifted or transferred to the ground. Since the loading and unloading of the drag chain is no longer dependent on manual labor, but the connection and disconnection of the drag chain is achieved by moving the flaw detection equipment with the device end assembly 10, while greatly improving the efficiency of power and water loading and unloading, it also reduces manual participation, which can effectively avoid the safety risks of manual participation in the loading and unloading of the drag chain.

[0031] As for the method of realizing the detachable connection between the intermediate switching assembly 20 and the docking base assembly 30, a connection form such as a snap connection or a buckle connection can be used. For example, an intermediate transition plate 27 can be connected to the side of the quick-change mechanism sub-disk 21 away from the quick-change mechanism main disk 12, and then at least two snap-in seats 39 can be dispersedly connected to the connecting plate 38, and the intermediate transition plate 27 and the snap-in seats 39 can be detachably snap-connected to realize the detachable connection between the two, thereby realizing the detachable connection between the intermediate switching assembly 20 and the docking base assembly 30. The snap-in seat 39 can be a mechanism with a spring and a movable latch inside, and the movable latch can be extended to lock the edge of the intermediate transition plate 27 with the cooperation of the spring, and can also be retracted into the snap-in seat 39 to enable the intermediate transition plate 27 to be detached.

[0032] In the process of the flaw detection equipment with the equipment end assembly 10 moving to the end of the maintenance trench and docking with the intermediate switching assembly 20, it may collide with the intermediate switching assembly 20 and the docking base assembly 30 due to untimely deceleration. In order to avoid such collision and damage to parts, the docking base assembly 30 described in the embodiment of the present application may also include an ear seat 32, an elastic buffer 34 and a sliding seat 36. The ear seat 32 is connected to the upper part of the base 31. The sliding seat 36 is slidably connected to the ear seat 32 along the front-to-back direction (the direction shown by the X-axis), which is consistent with the direction in which the equipment end assembly 10 moves relative to the docking base assembly 30. A pair of slide rails 35 can be set between the sliding seat 36 and the ear seat 32 to guide and constrain the direction and process of sliding movement. The elastic buffer 34 is connected between the ear seat 32 and the sliding seat 36 to buffer impact. The connecting plate 38 is connected to the sliding seat 36. In this way, when the device end component 10 hits the intermediate switching component 20 and the docking base component 30, the elastic buffer 34 can buffer the impact process and avoid damaging related parts. The elastic buffer 34 can be made of elastic recovery parts such as elastic rubber and springs. A limit connecting rod 33 can also be set between the sliding seat 36 and the base 31. The limit connecting rod 33 can be a screw with a nut head. After the screw passes through the sliding seat 36 and the base 31 in turn, the nut head is limited by the sliding seat 36, and the screw is limited by the nut screwed outside the base 31. In this way, the elastic buffer 34 can be prevented from applying excessive restoring force to the sliding seat 36, so that the sliding seat 36 will not fall off the slide rail 35.

[0033] If the flaw detection device with the device end assembly 10 is not completely aligned with the docking base assembly 30 during the movement, the final docking effect may be affected. Figure 5As shown, the docking base assembly 30 described in the embodiment of the present application may also include a back plate 370 and at least one first adjustment mechanism. The first adjustment mechanism includes a first connecting seat 3711, a first elastic reset member 3712, a first fixed seat 3713 and a first guide rod 3714. Two first fixed seats 3713 are arranged at a relative interval on one side of the back plate 370. A first guide rod 3714 is connected between the two first fixed seats 3713. The first connecting seat 3711 is slidably connected to the first guide rod 3714. The two first elastic reset members 3712 are respectively arranged on both sides of the first connecting seat 3711 and are sleeved on the first guide rod 3714. The first connecting seat 3711 is connected to the connecting plate 38. When there are more than two first adjustment mechanisms, the first adjustment mechanisms are arranged side by side on the back plate 370. The length direction of the first guide rod 3714 can be set to be parallel to the left and right direction indicated by the Y-axis. In this way, the deviation between the device-end component 10 and the docking base component 30 in the left and right direction can be corrected through the first adjustment mechanism, and the device-end component 10 and the docking base component 30 have greater docking adaptability and flexibility.

[0034] The docking base assembly 30 may also include at least one second adjustment mechanism. The second adjustment mechanism includes a second connecting seat 3721, a second elastic reset member 3722, a second fixed seat 3723 and a second guide rod 3724. The two second fixed seats 3723 are arranged at a relatively spaced interval on the side of the back plate 370 away from the connecting plate 38. A second guide rod 3724 is connected between the two second fixed seats 3723. The second connecting seat 3721 is slidably connected to the second guide rod 3724. The two second elastic reset members 3722 are respectively arranged on both sides of the second connecting seat 3721 and sleeved on the second guide rod 3724. The second connecting seat 3721 is connected to the sliding seat 36. When there are more than two second adjustment mechanisms, the second adjustment mechanisms are arranged side by side on the back plate 370. The second adjustment mechanism and the first adjustment mechanism are arranged non-parallel, and the minimum angle between the two is greater than 0 degrees and less than or equal to 90 degrees. For example, when the first adjustment mechanism is set parallel to the left and right direction shown by the Y-axis, the second adjustment mechanism can be set parallel to the up and down direction shown by the Z-axis. The first adjustment mechanism and the second adjustment mechanism can form a floating centering mechanism 37 to achieve plane displacement compensation during the overall plane docking process, which greatly reduces the docking accuracy requirements and improves the stability and smoothness of the docking process.

[0035] In order to improve the docking accuracy between the device-end component 10, the intermediate switching component 20 and the docking base component 30, the device described in the embodiment of the present application may also include a first guide tube 15, a first guide column 310, a second guide tube 26 and a second guide column 311.

[0036] The first guide tube 15 is installed on the device-end component 10, and the first guide column 310 is installed on the docking base component 30; or the first guide tube 15 is installed on the docking base component 30, and the first guide column 310 is installed on the device-end component 10. The first guide tube 15 and the first guide column 310 are used together to guide the docking action of the device-end component 10.

[0037] The second guide tube 26 is mounted on the intermediate switching assembly 20, and the second guide column 311 is mounted on the docking base assembly 30; or, the second guide tube 26 is mounted on the docking base assembly 30, and the second guide column 311 is mounted on the intermediate switching assembly 20. The second guide tube 26 and the second guide column 311 are used together to guide the docking action of the intermediate switching assembly 20.

[0038] In order to prevent the flaw detection device with the device end component 10 from excessive movement, the device described in the embodiment of the present application may also include a pair of matching proximity switches 16 and detection rods 312. Among them, the proximity switch 16 is installed on the device end component 10, and the detection rod 312 is installed on the docking base component 30; or, the proximity switch 16 is installed on the docking base component 30, and the detection rod 312 is installed on the device end component 10. In this way, when the detection rod 312 enters the detection range of the proximity switch 16, it can be considered that the flaw detection device has reached a suitable position and should stop moving forward to avoid collision or excessive collision. At this time, the detection signal of the proximity switch 16 can be used as a stop motion signal for the flaw detection device. At the same time, when the flaw detection device leaves, the detection signal of the proximity switch 16 can also be used as a feedback signal that the flaw detection device has left. The proximity switch 16 can be linked with the quick-change mechanism to improve the degree of automation and further reduce manual participation.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The above preferred embodiments shall not be regarded as limiting the present invention, and the protection scope of the present invention shall be subject to the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications shall also be regarded as the protection scope of the present invention.
