Description

Technical Field

[0001] The present application relates to the field of power supply, and in particular to a busbar carbon brush crossing mechanism and a construction elevator having the same. Background Art

[0002] In the field of power supply, equipment is often powered by cables. However, for mobile devices, since mobile devices need to constantly change positions, in each different position, the mobile device must be able to obtain power at any time, otherwise it will not be able to continue moving. The use of cables for power supply has defects such as easy damage and difficult maintenance, so the busbar (Isolated conductor rail, referred to as ICR) came into being. The busbar includes a busbar busbar (also called a transmission rail) laid parallel to the running track of the mobile device and a current collector arranged on the mobile device for drawing power from the busbar busbar. The current collector runs synchronously with the mobile device and obtains power from the busbar busbar at any time to provide it to the mobile device so that the mobile device can continue to move.

[0003] Although the existing busbars can support the power supply of multiple mobile devices on a single transmission rail to simplify the on-site wiring of multiple mobile devices, the relative positions of the mobile devices cannot be changed. In some application scenarios, in order to ensure that the mobile device can move freely in front of and behind other devices, a set of busbars has to be laid for the device to achieve independent power supply, which increases the project investment cost.

[0055] An embodiment of the present application provides a busbar carbon brush crossing mechanism for supplying power to a first mobile device and a second mobile device based on a busbar structure. While ensuring continuous power supply to each mobile device, it is possible to change the sequence and direction of operation of each mobile device, thereby satisfying the requirement of supplying power to multiple mobile devices with a single busbar set and allowing the mobile devices to move freely forward and backward.

[0056] like Figure 1 and Figure 2 As shown, the busbar carbon brush crossing mechanism of the embodiment of the present application includes: a busbar busbar 1, a first power supply device, a second power supply device, a third carbon brush 8, a fourth carbon brush 9, a first auxiliary busbar 10 and a second auxiliary busbar 11. The busbar busbar 1 is arranged along the unified moving direction of each mobile device to provide power supply. The first power supply device is connected to the first mobile device 4, and is used to supply power to the first mobile device 4 and move with the first mobile device 4. The first power supply device includes: a first carbon brush 2 that slides with the busbar busbar 1 and a first locking mechanism 3 that is fixedly connected to the first carbon brush 2. The second power supply device is connected to the second mobile device 7, and is used to supply power to the second mobile device 7 and move with the second mobile device 7. The second power supply device includes: a second carbon brush 5 that slides with the auxiliary busbar and a second locking mechanism 6 that is fixedly connected to the second carbon brush 5.

[0057] The third carbon brush 8 and the fourth carbon brush 9 are respectively located on both sides of the first carbon brush 2 and are slidably matched with the busbar 1. The first auxiliary busbar 10 and the second auxiliary busbar 11 are respectively located on both sides of the first carbon brush 2 and are on the same straight line. The first auxiliary busbar 10 is electrically connected to the third carbon brush 8 and moves with the third carbon brush 8. The second auxiliary busbar 11 is electrically connected to the fourth carbon brush 9 and moves with the fourth carbon brush 9.

[0058] In the embodiment of the present application, the first power taking device is fixed to one of the third carbon brush 8 and the fourth carbon brush 9 via the first locking mechanism 3, and the second power taking device is fixed to the other of the third carbon brush 8 and the fourth carbon brush 9 via the second locking mechanism 6. The first locking mechanism 3 and the second locking mechanism 6 are staggered in space, so that when the first power taking device and the second power taking device are swapped along the length direction of the busbar 1, the first locking mechanism 3 and the second locking mechanism 6 do not interfere with each other.

[0059] It can be understood that based on the cooperation between the first locking mechanism 3 and the second locking mechanism 6, the connection relationship between the first power supply device and the second power supply device and the third carbon brush 8 and the fourth carbon brush 9 on the busbar 1 can be switched during the process of exchanging the relative position relationship between the first mobile device 4 and the second mobile device 7, thereby ensuring the power supply reliability of the first mobile device 4 and the second mobile device 7 powered by the busbar structure while meeting the demand for automatic switching of the relative position relationship between the mobile devices.

[0060] It should be pointed out that the first mobile device 4 can directly draw power from the busbar 1 based on the first carbon brush 2 that slides with the busbar 1, so as to meet the demand for continuous and reliable power supply for the first mobile device 4; the second mobile device 7 draws power from the second carbon brush 5 that slides with the aforementioned first auxiliary busbar 10 and second auxiliary busbar 11 to achieve reliable power supply. Specifically, its power supply path can change after the front and rear operating order of the two mobile devices is changed. For example, when the second mobile device 7 is located on the left side of the first mobile device 4, the third carbon brush 8 can draw power from the busbar 1, and supply power to the second mobile device 7 through the first auxiliary busbar 10 and the second carbon brush 5 in turn. After the second mobile device 7 switches to the right side of the first mobile device 4, the fourth carbon brush 9 can draw power from the busbar 1, and supply power to the second mobile device 7 through the second auxiliary busbar 11 and the second carbon brush 5 in turn.

[0061] It should be noted that, during normal operation, due to the combined effect of the first locking mechanism 3 and the second locking mechanism 6, if the first locking mechanism 3 is locked with the third carbon brush 8, the second locking mechanism 6 will be locked with the fourth carbon brush 9, and vice versa. In this way, the third carbon brush 8 and the fourth carbon brush 9 can move with the two mobile devices.

[0062] Exemplarily, the first auxiliary bus bar 10 is fixedly connected to the third carbon brush 8 via the first structural member, and the first auxiliary bus bar 10 and the third carbon brush 8 are electrically connected via the first wire 14; the second auxiliary bus bar 11 is fixedly connected to the fourth carbon brush 9 via the second structural member, and the second auxiliary bus bar 11 and the fourth carbon brush 9 are electrically connected via the second wire 15; wherein, the first auxiliary bus bar 10 and the second auxiliary bus bar 11 are extended toward each other in the length direction of the bus bar bus 1, so that during the switching of the second locking mechanism 6 of the second power taking device between the third carbon brush 8 and the fourth carbon brush 9, the second carbon brush 5 can continuously slide on the first auxiliary bus bar 10 and the second auxiliary bus bar 11.

[0063] It should be noted that in the related technology, there is a structure that uses a guiding structure to realize the spatial switching of the collectors of the busbars of two mobile devices. However, in the above-mentioned spatial switching process, the carbon brush has to leave the busbar and then re-enter the busbar through a bridge mechanism, which has the following problems: 1) The busbar opening must be made larger, otherwise it is not conducive to the entry of the carbon brush during the bridge; 2) The busbar opening is too large, and there is a safety hazard in electricity use; 3) After the carbon brush leaves the busbar, it must be accurately positioned before it can re-enter the busbar, which increases the difficulty of design and production.

[0064] The embodiment of the present application introduces a first auxiliary bus bar 10 and a second auxiliary bus bar 11 extending in opposite directions, so that the second carbon brush 5 for drawing power from the second mobile device 7 can continuously slide on the first auxiliary bus bar 10 and the second auxiliary bus bar 11, thereby avoiding the trouble of reconnection caused by the carbon brush leaving the bus bar, and also enhancing the reliability and safety of power supply.

[0065] Exemplarily, the first structural member and / or the second structural member may be a frame structure, so that the first auxiliary busbar 10 can move following the third carbon brush 8, and the second auxiliary busbar 11 can move following the fourth carbon brush 9. The first auxiliary busbar 10 is electrically connected to the third carbon brush 8 and has the same phase sequence, and the second auxiliary busbar 11 is electrically connected to the fourth carbon brush 9 and has the same phase sequence, for example, the first auxiliary busbar 10 is electrically connected to the third carbon brush 8 via the first conductor 14 having the same phase sequence, and the second auxiliary busbar 11 is electrically connected to the fourth carbon brush 9 via the second conductor 15 having the same phase sequence.

[0066] Exemplarily, a first elastic element is disposed between the first auxiliary busbar 10 and the first structural member 12 ; and / or a second elastic element is disposed between the second auxiliary busbar 11 and the second structural member 13 .

[0067] It is understandable that when the first mobile device 4 and the second mobile device 7 are swapped, in order to reduce the impact when the devices are exchanged, the first elastic element and / or the second elastic element can be set to effectively reduce the impact pressure when the two auxiliary busbars are docked.

[0068] For example, in an application example, the busbar 1 is located on a first plane, and the first auxiliary busbar 10 and the second auxiliary busbar 11 are located on a second plane, wherein the second plane is perpendicular to the first plane. In this way, the busbar 1 and the auxiliary busbars can be arranged on two planes perpendicular to each other to achieve a spatial dislocation arrangement, so as to facilitate the dislocation switching of the first mobile device 4 and the second mobile device 7 when the spatial positions are exchanged. For example, the busbar 1 is arranged along a horizontal plane, the first auxiliary busbar 10 and the second auxiliary busbar 11 can be arranged on a side perpendicular to the horizontal plane, the second carbon brush 5 is arranged perpendicular to the first carbon brush 2, the second carbon brush 5 can be located above the first carbon brush 2, and the second locking mechanism 6 can be located above the second locking mechanism 6, so that the first carbon brush 2 and the second carbon brush 5, as well as the first locking mechanism 3 and the second locking mechanism 6 do not interfere with each other.

[0069] In another application example, the busbar 1 is located on a first plane, and the first auxiliary busbar 10 and the second auxiliary busbar 11 are located on a third plane that is offset from the first plane in the height direction. In this way, the busbar 1 and the auxiliary busbars can be arranged in a staggered manner on two parallel planes that are spaced and staggered in space, so as to facilitate the staggered switching of the first mobile device 4 and the second mobile device 7 when the spatial positions are exchanged. For example, the busbar 1 is arranged along a horizontal plane, the first auxiliary busbar 10 and the second auxiliary busbar 11 can be arranged in the horizontal plane direction, the second carbon brush 5 can be located above the first carbon brush 2, and the second locking mechanism 6 can be located above the second locking mechanism 6, so that the first carbon brush 2 and the second carbon brush 5, as well as the first locking mechanism 3 and the second locking mechanism 6 do not interfere with each other.

[0070] In another application example, the busbar 1 is located on a first plane, and the first auxiliary busbar 10 and the second auxiliary busbar 11 are also located on the first plane, but the straight line where the auxiliary busbar is located needs to be parallel and spaced apart from the straight line where the busbar 1 is located. In this way, it is easy to realize the staggered switching when the first mobile device 4 and the second mobile device 7 are exchanged in space. For example, the busbar 1 is arranged along a horizontal plane, the first auxiliary busbar 10 and the second auxiliary busbar 11 can be arranged on a horizontal plane, the second carbon brush 5 is parallel and spaced apart from the first carbon brush 2, and the second locking mechanism 6 can be located above the second locking mechanism 6, so that the first carbon brush 2 and the second carbon brush 5, as well as the first locking mechanism 3 and the second locking mechanism 6 do not interfere with each other.

[0071] Exemplarily, the first locking mechanism 3 includes a third structural member for connecting the first moving device 4, and the first locking mechanism 3 also includes a first fixing rod extending to both sides along the length direction of the busbar 1 and a first locking member for locking; the third carbon brush 8 and the fourth carbon brush 9 are both provided with a first positioning hole for cooperating with the first fixing rod and an elastic element for cooperating with the first locking member.

[0072] It can be understood that the first moving device 4 can drive the first carbon brush 2 and the first locking mechanism 3 to move synchronously via the third structural member, and the first locking mechanism 3 can selectively lock the third carbon brush 8 or the fourth carbon brush 9 through the cooperation of the first fixing rod and the first positioning hole, and the first locking member and the elastic element, and drive the third carbon brush 8 and the first auxiliary bus bar 10 to move, or drive the fourth carbon brush 9 and the second auxiliary bus bar 11 to move.

[0073] Exemplarily, the second locking mechanism 6 includes a fourth structural member for connecting the second moving device 7, and the second locking mechanism 6 also includes a second fixing rod extending to both sides along the length direction of the busbar 1 and a second locking member for locking; the third carbon brush 8 and the fourth carbon brush 9 are both provided with a second positioning hole for cooperating with the second fixing rod and a locking element for cooperating with the second locking member.

[0074] It can be understood that the second moving device 7 can drive the second carbon brush 5 and the second locking mechanism 6 to move synchronously via the fourth structural member, and the second locking mechanism 6 can selectively lock the third carbon brush 8 or the fourth carbon brush 9 through the cooperation between the second fixing rod and the second positioning hole, and the second locking member and the locking element, and drive the third carbon brush 8 and the first auxiliary bus bar 10 to move, or drive the fourth carbon brush 9 and the second auxiliary bus bar 11 to move.

[0075] Exemplarily, the third carbon brush 8 and the fourth carbon brush 9 also include an elastic trigger mechanism for switching the working state of the locking element, wherein the elastic trigger mechanism has a sensing part located in the first positioning hole, and if the first fixing rod is located in the first positioning hole, the elastic trigger mechanism unlocks the connection between the locking element and the second locking member based on the pressure change of the sensing part; if the first fixing rod is detached from the first positioning hole, the elastic trigger mechanism locks the connection between the locking element and the second locking member based on the pressure change of the sensing part.

[0076] It can be understood that the elastic trigger mechanism can achieve the unlocking of the third carbon brush 8 or the fourth carbon brush 9 and the second locking mechanism 6 on the side of the second moving device 7 when the first locking mechanism 3 on the side of the first moving device 4 contacts the third carbon brush 8 or the fourth carbon brush 9. For example, when the first moving device 4 drives the fourth carbon brush 9 to move to the left via the first locking mechanism 3, and the second moving device 7 drives the third carbon brush 8 to move to the right via the second locking mechanism 6, when the first locking mechanism 3 contacts the third carbon brush 8, that is, when the first fixing rod extends into the first positioning hole on the side of the third carbon brush 8, the elastic trigger mechanism can unlock the connection between the second locking mechanism 6 and the third carbon brush 8, so that the second locking mechanism 6 can continue to move to the right under the drive of the second moving device 7.

[0077] Exemplarily, the second locking mechanism 6 is located above the first locking mechanism 3, and the second locking piece is a boss protruding toward the elastic element, so that when the boss contacts the elastic element, the connection between the elastic element and the first locking piece is unlocked.

[0078] It can be understood that, based on the matching relationship between the boss and the elastic element, when the second locking mechanism 6 on the side of the second mobile device 7 contacts the third carbon brush 8 or the fourth carbon brush 9, the third carbon brush 8 or the fourth carbon brush 9 can be unlocked from the first locking mechanism 3 on the side of the first mobile device 4. For example, when the first mobile device 4 drives the fourth carbon brush 9 to move to the left via the first locking mechanism 3, and the second mobile device 7 drives the third carbon brush 8 to move to the right via the second locking mechanism 6, when the second locking mechanism 6 contacts the fourth carbon brush 9, that is, when the boss abuts against the elastic element on the side of the fourth carbon brush 9, the connection between the first locking mechanism 3 and the fourth carbon brush 9 can be unlocked, so that the first locking mechanism 3 can continue to move to the left under the drive of the first mobile device 4.

[0079] It should be noted that when the first mobile device 4 and the second mobile device 7 are moving towards each other, as the two mobile devices get closer, they need to switch the locked carbon brushes (i.e., switch the third carbon brush 8 and the fourth carbon brush 9). The following is an exemplary explanation using the example of the first mobile device 4 driving the fourth carbon brush 9 to move to the left and the second mobile device 7 driving the third carbon brush 8 to move to the right.

[0080] like Figure 3As shown, when the second moving device 7 is locked with the third carbon brush 8 through the second locking mechanism 6, the third carbon brush 8 follows the second moving device 7 to run synchronously; the first moving device 4 is locked with the fourth carbon brush 9 through the first locking mechanism 3, so that the fourth carbon brush 9 follows the first moving device 4 to run synchronously. At this time, the power supply of the busbar 1 is transmitted to the first auxiliary busbar 10 through the third carbon brush 8 and the first conductor 14, and the second moving device 7 obtains the power supply from the second carbon brush 5 connected to the first auxiliary busbar 10 for sliding; at the same time, the power supply of the busbar 1 is directly obtained through the first carbon brush 2 of the first moving device 4, and the first moving device 4 locks the fourth carbon brush 9 through the first locking mechanism 3 and makes it move together.

[0081] If the two mobile devices move in opposite directions, there is no change in the front-to-back order of the two mobile devices, and each of them operates by the power supply obtained from the busbar 1.

[0082] If the two mobile devices move towards each other and the positions of the two mobile devices gradually approach each other, the second locking mechanism 6 will come into contact with the fourth carbon brush 9 and unlock the first locking mechanism 3 of the first mobile device 4 at the same time, so that the first mobile device 4 and the fourth carbon brush 9 are unlocked and separated. When the first mobile device 4 is separated from the fourth carbon brush 9 by a certain distance, the locking element of the fourth carbon brush 9 will be triggered, so that the second mobile device 7 will be locked with the fourth carbon brush 9, so that the fourth carbon brush 9 follows the movement of the second mobile device 7; for example, when the first locking mechanism 3 is mobilized by the first mobile device 4, the first fixing rod is disengaged from the first positioning hole of the fourth carbon brush 9, and the elastic trigger mechanism locks the connection between the locking element on the side of the fourth carbon brush 9 and the second locking member based on the pressure change of the sensing part, so that the second mobile device 7 is locked with the fourth carbon brush 9.

[0083] It can be understood that the first locking mechanism 3 of the first moving device 4 will come into contact with the third carbon brush 8, and at the same time unlock the connection between the second moving device 7 and the third carbon brush 8, for example, the first fixing rod enters the first positioning hole, so that the second locking member of the second locking mechanism 6 is unlocked and separated from the locking element on the side of the third carbon brush 8. When the second locking mechanism 6 of the second moving device 7 is separated from the third carbon brush 8 by a certain distance, the elastic element of the third carbon brush 8 will also be triggered to spring up, so that the first locking mechanism 3 of the first moving device 4 is locked with the third carbon brush 8, so that the third carbon brush 8 follows the operation of the first moving device 4.

[0084] It can be understood that the power supply of the first mobile device 4 has been provided by the first carbon brush 2 through the busbar 1; during the above switching process, the power supply source of the second mobile device 7 has changed. When the two mobile devices move toward each other, the first locking mechanism 3 will contact the third carbon brush 8, and the second locking mechanism 6 will contact the fourth carbon brush 9. At the same time, the first auxiliary busbar 10 will contact the second auxiliary busbar 11. If the second mobile device 7 continues to move to the right at this time, it will drive the second carbon brush 5 and the second locking mechanism 6 to move to the right, and the second carbon brush 5 will slide from the first auxiliary busbar 10 to the second auxiliary busbar 11 until the second locking mechanism 6 contacts the fourth carbon brush 9. If the second mobile device 7 continues to move to the right, its power source has changed at this time, and the fourth carbon brush 9 draws electricity from the busbar 1, and obtains electrical energy through the second conductor 15, the second auxiliary busbar 11, and then through the second carbon brush 5. At this time, the second mobile device 7 can continue to run normally to the right, realizing the exchange of the front and back running order of the two devices. The power supply state after the exchange is as follows: Figure 4 shown.

[0085] The busbar carbon brush crossing mechanism of the embodiment of the present application is exemplarily described below in conjunction with the application examples.

[0086] Application Example 1

[0087] In this application embodiment, Figure 5 As shown, the busbar 1 is arranged horizontally, and the first auxiliary busbar 10 and the second auxiliary busbar 11 are arranged vertically, that is, the plane where the busbar 1 is located is perpendicular to the plane where the auxiliary busbars are located.

[0088] like Figure 5 As shown, the first locking mechanism 3 includes a first locking mechanism for connecting the first mobile device 4 ( Figure 5 The third structural member 31 (not shown) may include two connecting rods fixed to the first mobile device 4, so that the first locking mechanism 3 and the first carbon brush 2 follow the movement driven by the first mobile device 4; the second locking mechanism 6 includes a third structural member 31 for connecting the second mobile device 7 ( Figure 5 The fourth structural member 61 (not shown) may include two connecting rods fixed to the second moving device 7, so that the second locking mechanism 6 and the second carbon brush 5 move along with the second moving device 7.

[0089] The third carbon brush 8 is connected to the first auxiliary busbar 10 via the first structural member 12, and the fourth carbon brush 9 is connected to the second auxiliary busbar 11 via the second structural member 13. The third carbon brush 8 can be understood as the left auxiliary carbon brush, and the fourth carbon brush 9 can be understood as the right auxiliary carbon brush. The first locking mechanism 3 is provided with a first fixing rod 32 and a first locking member 33, and the second locking mechanism 6 is provided with a second fixing rod 62 and a second locking member 63. The third carbon brush 8 is provided with a left first positioning hole 81, a left elastic element 82, a left second positioning hole 83 and a left locking member 84, wherein the left first positioning hole 81 is provided correspondingly to the first fixing rod 32, the left elastic element 82 is provided correspondingly to the first locking member 33, the left second positioning hole 83 is provided correspondingly to the second fixing rod 62, and the left locking member 84 is provided correspondingly to the second locking member 63. The fourth carbon brush 9 is provided with a right-side first positioning hole 91, a right-side elastic element 92, a right-side second positioning hole 93 and a right-side locking element 94, wherein the right-side first positioning hole 91 is provided corresponding to the first fixing rod 32, the right-side elastic element 92 is provided corresponding to the first locking piece 33, the right-side second positioning hole 93 is provided corresponding to the second fixing rod 62, and the right-side locking element 94 is provided corresponding to the second locking piece 63.

[0090] Exemplarily, the left elastic element 82 and the right elastic element 92 can be understood as a resistance member with a spring installed at the bottom, and the left locking element 84 and the right locking element 94 can be elastic structures. When the first fixed rod 32 is inserted into the right first positioning hole 91 (that is, the first moving device 4 drives the first locking mechanism 3 to move right to connect the fourth carbon brush 9), under the triggering of the elastic trigger mechanism, the right locking element 94 sinks, and the second locking mechanism 6 can pass freely (that is, the second moving device 7 can drive the second locking mechanism 6 to move freely to the left and unlock the connection with the fourth carbon brush 9). Once the first fixed rod 32 leaves the right first positioning hole 91 (that is, the first moving device 4 drives the first locking mechanism 3 to move left and leave the fourth carbon brush 9), the right locking element 94 rises to prevent the second locking mechanism 6 from leaving the fourth carbon brush 9 (that is, the locking of the second locking mechanism 6 and the fourth carbon brush 9 is achieved).

[0091] Similarly, when the first fixing rod 32 is inserted into the first positioning hole 81 on the left side (that is, the first moving device 4 drives the first locking mechanism 3 to move left to connect the third carbon brush 8), under the triggering of the elastic trigger mechanism, the left locking element 84 sinks, and the second locking mechanism 6 can pass freely (that is, the second moving device 7 can drive the second locking mechanism 6 to move right freely to unlock the connection with the third carbon brush 8). Once the first fixing rod 32 leaves the first positioning hole 81 on the left side (that is, the first moving device 4 drives the first locking mechanism 3 to move right and leave the third carbon brush 8), the left locking element 84 rises to prevent the second locking mechanism 6 from leaving the third carbon brush 8 (that is, the second locking mechanism 6 and the third carbon brush 8 are locked).

[0092] Figure 5 It is a schematic diagram of the overall component composition, not a normal working state diagram. Under normal working conditions, the first locking mechanism 3 must be connected to one of the third carbon brush 8 or the fourth carbon brush 9, and if the first locking mechanism 3 is connected to the fourth carbon brush 9, the second locking mechanism 6 must be connected to the third carbon brush 8, and vice versa.

[0093] The basic working process of the busbar carbon brush crossing mechanism of this application embodiment is as follows:

[0094] like Figure 6 As shown, when the second moving device 7 drives the second carbon brush 5 and the second locking mechanism 6 to move to the right, one end of the second fixing rod 62 will be inserted into the second positioning hole 93 on the right side. At the same time, the bottom of the second locking member 63 will press the right elastic element 92 with a supporting spring installed at the bottom, so that the right elastic element 92 cannot hook the first locking member 33, thereby unlocking the fourth carbon brush 9 and the first locking mechanism 3; when the second moving device 7 continues to move to the right or the first moving device 4 moves to the left, the first fixing rod 32 will leave the first positioning hole 91 on the right side, and the right locking element 94 will rise to prevent the second locking mechanism 6 from leaving the fourth carbon brush 9 (that is, the second locking mechanism 6 is locked and connected to the fourth carbon brush 9); at this time, the second moving device 7 will be able to continue to run on the busbar 1 with the fourth carbon brush 9.

[0095] Exemplarily, an elastic buffer member 16 for buffering may be provided between the second auxiliary busbar 11 and the second structural member 13 to mitigate the buffering force during the docking process between the first auxiliary busbar 10 and the second auxiliary busbar 11 .

[0096] The power supply switching in the above switching process is as follows: in the initial state, the power supply of the second mobile device 7 flows through the busbar 1, the third carbon brush 8, the first auxiliary busbar 10 and the second carbon brush 5. As the second mobile device 7 approaches the first mobile device 4, the first auxiliary busbar 10 and the second auxiliary busbar 11 are close to each other, so that the second carbon brush 5 can continue to move to the right with the second mobile device 7, and the second carbon brush 5 slides from the first auxiliary busbar 10 to the second auxiliary busbar 11. When the second locking mechanism 6 and the fourth carbon brush 9 are locked normally, the power supply of the second mobile device 7 is changed to be obtained through the busbar 1, the fourth carbon brush 9, the second auxiliary busbar 11 and the second carbon brush 5, thereby realizing the cross-power supply of the two mobile devices. Figure 7 It is a schematic diagram after the second locking mechanism 6 of the second moving device 7 is connected to the fourth carbon brush 9 and the first carbon brush 2 of the first moving device 4 is connected to the third carbon brush 8, Figure 8 for Figure 7 A front view schematic diagram of .

[0097] Application Example 2

[0098] In this application embodiment, Fig. 9 As shown, the busbar 1, the first auxiliary busbar 10 and the second auxiliary busbar 11 are all arranged horizontally.

[0099] like Fig. 9 As shown, the busbar carbon brush crossing mechanism includes: busbar busbar 1, first power taking device, second power taking device, third carbon brush 8, fourth carbon brush 9, first auxiliary busbar 10 and second auxiliary busbar 11. The third carbon brush 8 and the fourth carbon brush 9 are respectively located on both sides of the first carbon brush 2 and both slide with the busbar busbar 1. The first auxiliary busbar 10 and the second auxiliary busbar 11 are respectively located on both sides of the first carbon brush 2 and are in the same straight line. The first auxiliary busbar 10 is electrically connected to the third carbon brush 8 and moves with the third carbon brush 8. The second auxiliary busbar 11 is electrically connected to the fourth carbon brush 9 and moves with the fourth carbon brush 9.

[0100] The first power extraction device is connected to the first mobile device 4 ( Fig. 9 The first power supply device includes: a first carbon brush 2 that slides with the busbar 1 and a first locking mechanism 3 that is fixedly connected to the first carbon brush 2. The second power supply device is connected to the second mobile device 7 ( Fig. 9 The second power supply device (not shown) is used to supply power to the second mobile device 7 and move with the second mobile device 7. The second power supply device includes: a second carbon brush 5 that slides with the auxiliary busbar and a second locking mechanism 6 that is fixedly connected to the second carbon brush 5.

[0101] like Fig.10 As shown, the first locking mechanism 3 includes a third structural member 31 (which may be a connecting base) for connecting the first moving device 4, and the first locking mechanism 3 also includes a first fixing rod 32 extending to both sides along the length direction of the busbar 1, and the first locking member 33 may be a buckle portion (such as a buckle groove) provided on the first fixing rod 32. Fig.11As shown, the second locking mechanism 6 includes a fourth structural member 61 (which may be a connecting base) for connecting the second mobile device 7, and the second locking mechanism 6 also includes a second fixing rod 62 extending to both sides along the length direction of the busbar 1, and the second locking member 63 may be a buckle portion (such as a buckle groove) provided on the second fixing rod 62. It should be noted that the third carbon brush 8 and the fourth carbon brush 9 are both provided with a first positioning hole for cooperating with the first fixing rod 32 and a second positioning hole for cooperating with the second fixing rod 62; in addition, an elastic element for locking or unlocking the first locking member 33 based on elastic triggering is provided in the first positioning hole, and a locking element for locking or unlocking the second locking member 63 based on elastic triggering is provided in the second positioning hole. Among them, the elastic element and / or the locking element may be an elastic buckle structure cooperating with the aforementioned buckle portion, such as an elastic buckle boss, etc., which is not limited in the embodiment of the present application.

[0102] Exemplarily, a first buffer spring 34 may be provided on the first fixing rod 32 , and a second buffer spring 64 may be provided on the second fixing rod 62 , which may produce a buffering effect when the first locking mechanism 3 , the second locking mechanism 6 and the third carbon brush 8 , the fourth carbon brush 9 are connected and locked.

[0103] It should be noted that the power supply of the second moving device 7 is obtained through the second carbon brush 5, and the second carbon brush 5 slides on the first auxiliary bus bar 10 and the second auxiliary bus bar 11. When the second locking mechanism 6 is connected to the third carbon brush 8 through the second fixing rod 62 and the second positioning hole, the power supply of the second moving device 7 is obtained by the bus bar bus 1 through the third carbon brush 8, the first auxiliary bus bar 10 and the second carbon brush 5; and when the second locking mechanism 6 of the second moving device 7 is locked and connected with the fourth carbon brush 9, the power supply of the second moving device 7 is obtained by the bus bar bus 1 through the fourth carbon brush 9, the second auxiliary bus bar 11 and the second carbon brush 5.

[0104] Exemplarily, the first locking mechanism 3 is locked and connected to one of the third carbon brush 8 and the fourth carbon brush 9 through the first fixing rod 32 and the first locking piece 33, and the second locking mechanism 6 is locked and connected to the other of the third carbon brush 8 and the fourth carbon brush 9 through the second fixing rod 62 and the second locking piece 63, and the first locking mechanism 3 and the second locking mechanism 6 are staggered in the horizontal direction, thereby realizing the switching of the relative position relationship between the first mobile device and the second mobile device and continuous power supply.

[0105] Exemplarily, an embodiment of the present application further provides a construction elevator, including the aforementioned busbar carbon brush crossing mechanism, which can power the first cage and the second cage based on the busbar carbon brush crossing mechanism, that is, the first mobile device is the first cage, and the second mobile device is the second cage. It should be noted that for a construction elevator powered by a DC bus, if a transmission rail with multiple power supply electrodes is used, the number of transmission rails can be reduced to one, and the positive and negative poles of the DC bus share the same transmission rail. The first cage and the second cage can share a transmission rail through the aforementioned busbar carbon brush crossing mechanism, thereby realizing the power supply of the DC bus. In this way, the deployment cost of the transmission rail on the construction elevator can be further reduced. It can be understood that the aforementioned use of the transmission rail has the advantages of being conducive to the online utilization of power generation energy and effectively reducing the inductance during the working process compared to the power cable.

[0106] In practical applications, for a transmission rail with multiple power supply electrodes, an insulating protection structure can be provided between each power supply electrode to avoid short circuits between electrodes; accordingly, an insulating protection structure also needs to be provided between each contact part on the brush to meet safety precautions. It should be noted that the technical solutions described in the embodiments of the present application can be combined arbitrarily without conflict.

[0107] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
