[0011] Specifically, the linkage assembly comprises a plug-in piece, a positioning piece, a first connecting piece and a second connecting piece; one end of the positioning piece is a positioning end, and the other end is a free end; the free end of the positioning piece is formed with a linkage portion, and the linkage portion abuts against the second transmission member; one end of the first connecting piece is rotationally connected with the positioning end of the positioning piece, and the other end of the first connecting piece is connected with a first position of the plug-in piece; one end of the second connecting piece is connected with the free end of the positioning piece, and the other end of the second connecting piece is connected with a second position of the plug-in piece; a third position of the plug-in piece is formed with a plug-in portion, and the plug-in portion is plugged into the transmission disc.

[0012] Further, the transmission operation assembly comprises a transmission disc and a transmission disc; the transmission disc is formed with a plug-in portion corresponding to the position of the plug-in portion, and the transmission disc is connected with the transmission disc to drive the transmission disc to rotate.

[0013] The multi-stage interlocking operator further comprises a mounting panel, the unlocking mechanism, the reversing mechanism and the speed change mechanism are connected with the mounting panel.

[0015] Compared with the prior art, the multi-stage interlocking operator has the following advantages:

[0016] The multi-stage interlocking operator comprises an unlocking mechanism, a reversing mechanism, a speed change mechanism, a first transmission member and a second transmission member; the first transmission member is located between the unlocking mechanism and the reversing mechanism, the speed change mechanism comprises a speed change control assembly and a linkage assembly, the second transmission member is located between the reversing mechanism and the linkage assembly, the unlocking mechanism is formed with a first recess, the reversing mechanism is formed with a second recess, a third recess and a fourth recess; when locked, one end of the first transmission member is located in the second recess, one end of the second transmission member is located between the third recess and the fourth recess, and the other end of the second transmission member abuts against the linkage assembly, so that the linkage assembly abuts against the speed change control assembly, and the linkage assembly can make the second transmission member have a tendency to move close to the reversing mechanism.

Therefore, when the reversing mechanism cannot rotate, the second transmission member cannot act, so that the unlocking mechanism, the reversing mechanism and the speed change mechanism are locked.

[0019] When the unlocking mechanism rotates and the first recess is aligned with the first transmission component, the first transmission component can enter the first recess, so that the first transmission component has a space for moving close to the unlocking mechanism when the reversing mechanism rotates, thereby achieving unlocking of the reversing mechanism.

[0020] Correspondingly, after the end of the second transmission component enters the third recess or the fourth recess, the linkage assembly is released, thereby unlocking the speed change control assembly.

[0021] When the speed change control assembly returns to the initial position again, the linkage assembly abuts against the speed change control assembly again, so that the second transmission component returns to the initial position, and the end of the second transmission component can be separated from the third recess or the fourth recess, so that the reversing mechanism can rotate.

[0037] As Figure 1 In combination Figure 2 As shown in the utility model provides a kind of multistage interlocking operator, including unlocking mechanism 1, reversing mechanism 2, gear shift mechanism 3, first transmission member 4 and second transmission member 5;First transmission member 4 is located between unlocking mechanism 1 and reversing mechanism 2, gear shift mechanism 3 includes gear shift control assembly 301 and linkage assembly 302, second transmission member 5 is located between reversing mechanism 2 and linkage assembly 302, unlocking mechanism 1 is formed with first recess 1061, reversing mechanism 2 is formed with second recess 2031, third recess 2032 and fourth recess 2033;Locking, one end of first transmission member 4 is located in second recess 2031, one end of second transmission member 5 is located between third recess 2032 and fourth recess 2033, the other end is abutted with linkage assembly 302, so that linkage assembly 302 is abutted gear shift control assembly 301.

[0038] Compared with the prior art, the multistage interlocking operator provided by the utility model has the following advantages:

[0039] The first recess 1061 formed by the unlocking mechanism 1 can accommodate one end of the first transmission member 4, and correspondingly, the second recess 2031 formed by the reversing mechanism 2 can accommodate the other end of the first transmission member 4. In actual operation, when the first recess 1061 of the unlocking mechanism 1 is rotated in front of the first transmission member 4, one end of the first transmission member 4 is always in abutment with the unlocking mechanism 1, while the other end is embedded in the second recess 2031 and cannot be separated from the second recess 2031. Therefore, the reversing mechanism 2 cannot be rotated.

[0040] At the same time, since the third recess 2032 and the fourth recess 2033 formed by the reversing mechanism 2 are spaced apart, and in the locked state, the second transmission member 5 is in abutment with the position between the third recess 2032 and the fourth recess 2033, while the other end of the second transmission member 5 is in abutment with the linkage assembly 302, so that the linkage member is in abutment with the gear shift control assembly 301. Therefore, when the reversing mechanism 2 cannot be rotated, the second transmission member 5 cannot be actuated, so that the unlocking mechanism 1, the reversing mechanism 2 and the gear shift mechanism 3 are locked.

[0041] When the unlocking mechanism 1 rotates and the first recess 1061 is aligned with the first transmission member 4, the first transmission member 4 can enter the first recess 1061, so that the first transmission member 4 has a space to move close to the unlocking mechanism 1 when the reversing mechanism 2 rotates, thereby achieving unlocking of the reversing mechanism 2. When the reversing mechanism 2 is unlocked and rotated, and the second transmission member 5 is aligned with the third recess 2032 or the fourth recess 2033, the linkage assembly 302 in the present application enables the second transmission member 5 to have a tendency to move close to the reversing mechanism 2, so that one end of the second transmission member 5 can enter the third recess 2032 or the fourth recess 2033 after alignment.

[0042] Correspondingly, after one end of the second transmission member 5 enters the third recess 2032 or the fourth recess 2033, the linkage assembly 302 is released, thereby unlocking the speed control assembly 301. It can be understood that the linkage assembly 302 cannot return to the initial position due to the action of the speed control assembly 301, so the second transmission member 5 is always in the state of being in the third recess 2032 or the fourth recess 2033, thereby keeping the reversing mechanism 2 in the locked state.

[0043] When the speed control assembly 301 returns to the initial position again, the linkage assembly 302 abuts against the speed control assembly 301 again, so that the second transmission member 5 can return to the initial position, and then one end of the second transmission member 5 can be separated from the third recess 2032 or the fourth recess 2033, so that the reversing mechanism 2 can rotate. When the reversing mechanism 2 rotates and the second transmission member 5 does not enter the third recess 2032 or the fourth recess 2033, the speed control assembly 301 cannot be controlled, thereby achieving mutual locking of the unlocking mechanism 1, the reversing mechanism 2, and the speed control mechanism 3, avoiding the problem of mistakenly touching the speed control mechanism 3 during the reversing process and mistakenly touching the reversing mechanism 2 during the speed control process, and improving the safety of train driving.

[0044] Optionally, as shown in Figure 1 In combination Figure 2 The unlocking mechanism 1 in the present application includes an unlocking control assembly and a first wheel body 106, the reversing mechanism 2 includes a reversing control assembly and a second wheel body 203, the first recess 1061 is formed on the first wheel body 106, the second recess 2031, the third recess 2032, and the fourth recess 2033 are all formed on the second wheel body 203, and the third recess 2032 and the fourth recess 2033 are arranged at intervals to form an abutting portion between the third recess 2032 and the fourth recess 2033, and the second recess 2031 is arranged opposite to the abutting portion; the unlocking control assembly is connected with the first wheel body 106 to drive the first wheel body 106 to rotate, and the reversing control assembly is connected with the second wheel body 203 to drive the second wheel body 203 to rotate.

[0045] It can be understood that the controller provided by the application further comprises a mounting panel 6, and correspondingly, the unlocking mechanism 1, the reversing mechanism 2 and the gear shifting mechanism 3 are connected with the mounting panel 6, and in order to facilitate the operation of the driver, the operation end of the unlocking control assembly, the operation end of the reversing control assembly and the operation end of the gear shifting control assembly 301 in the application are exposed to the mounting panel 6, and in order to ensure the safety of the interlocking structure, the first wheel body 106, the second wheel body 203, the linkage assembly 302, the first transmission member 4 and the second transmission member 5 are all arranged below the mounting panel 6, therefore, the unlocking control assembly, the reversing control assembly and the gear shifting control assembly 301 provided by the application can realize the requirement that the operation end is arranged opposite to the interlocking end with respect to the mounting panel 6, and the safety of the whole device is ensured.

[0046] Optionally, as shown in Figure 3 The unlocking control assembly in the application comprises an unlocking piece 101 and a first matching member, the first matching member is formed with an unlocking hole 1021, the unlocking piece 101 is inserted into the unlocking hole 1021 to drive the first matching member to rotate; the first matching member is connected with the first wheel body 106 to drive the first wheel body 106 to rotate, thereby realizing the interlocking action described above.

[0047] Correspondingly, when the unlocking piece 101 is pulled out of the unlocking hole 1021, the first matching member cannot rotate, thereby the subsequent rotation of the reversing mechanism 2 and the gear shifting mechanism 3 cannot be realized, so as to ensure the starting safety of the whole device.

[0048] Optionally, as shown in Figure 3 In combination with Figure 4 The first matching member in the application comprises a core 102 and a shell 103; the core 102 is arranged in the shell 103 and can rotate relative to the shell 103, the outer wall of the core 102 is formed with an abutting column 1023, the shell 103 is formed with a limiting gap 1031 at the position corresponding to the abutting column 1023, and the first end surface 1032 and the second end surface 1033 of the limiting gap 1031 are arranged at an angle, so as to limit the rotation angle of the core 102 relative to the shell 103.

[0049] Preferably, the included angle between the first end surface 1032 and the second end surface 1033 of the limiting gap 1031 in the application is 90°, correspondingly, when the abutting column 1023 changes from the state of abutting the first end surface 1032 to the state of abutting the second end surface 1033, the core 102 rotates by 90°, and the first wheel body 106 can synchronously rotate by 90° with the core 102, so that the first recess 1061 formed on the first wheel body 106 can rotate by 90°.

[0050] It can be understood that when the abutting column 1023 is attached to the first end surface 1032, the core 102 is in the locked position, that is, the first recess 1061 on the first wheel body 106 is in the misaligned state with the first transmission member 4, and the first transmission member 4 cannot move, thereby locking the subsequent mechanism, and when the abutting column 1023 is attached to the second end surface 1033, the core 102 is in the unlocked position, that is, the first recess 1061 is rotated to the position opposite to the first transmission member 4, so that the first transmission member 4 has a moving space, thereby realizing the unlocking of the subsequent mechanism.

[0051] Optionally, as shown in Figure 4 The unlocking member 101 further comprises a first locking piece 104, a second locking piece 105, and an elastic piece. The unlocking hole 1021 extends along the axial direction of the core 102, and the core 102 is provided with a positioning hole 1022. The outer shell 103 is provided with an accommodating hole 1034. The positioning hole 1022 and the unlocking hole 1021 are in communication, and the accommodating hole 1034 is opposite to the positioning hole 1022. One end of the elastic piece is in abutment with the bottom of the accommodating hole 1034, and the other end is connected with one end of the second locking piece 105. The other end of the second locking piece 105 is in abutment with one end of the first locking piece 104, so that the other end of the first locking piece 104 can enter the unlocking hole 1021.

[0052] Before the unlocking member 101 is inserted into the unlocking hole 1021, the elastic piece pushes the second locking piece 105 to move forward, thereby pushing part of the first locking piece 104 to enter the unlocking hole 1021 and part of the first locking piece 104 to enter the positioning hole 1022. Correspondingly, part of the second locking piece 105 is located in the positioning hole 1022 and part of the second locking piece 105 is located in the positioning hole 1022 under the action of the elastic piece, so that the core 102 and the outer shell 103 can be locked under the action of the second locking piece 105, and the core 102 cannot rotate relative to the outer shell 103.

[0053] When the unlocking member 101 is inserted into the unlocking hole 1021, the first locking piece 104 is retracted into the positioning hole 1022 under the action of the unlocking member 101, and part of the first locking piece 104 is located in the positioning hole 1022 and part of the first locking piece 104 is located in the accommodating hole 1034. The second locking piece 105 is completely located in the accommodating hole 1034 to compress the elastic piece, so that the core 102 and the outer shell 103 are relatively locked by the first locking piece 104 in this state.

[0054] When the alignment gap 1011 of the unlocking piece 101 is aligned with the alignment hole 1022, the first locking piece 104 obtains a moving space, the rebound of the elastic piece pushes the second locking piece 105 to advance, thereby driving the first locking piece 104 to advance, so that part of the first locking piece 104 is located in the alignment gap 1011 and the other part is located in the alignment hole 1022, at the same time, the second locking piece 105 can be just completely located in the containing hole 1034, thereby realizing the unlocking between the core 102 and the shell 103, and the unlocking piece 101 is screwed to realize the rotation of the core 102 and complete the unlocking.

[0055] It should be noted here that the number of the alignment gap 1011 in the present application is one, which can reduce the processing difficulty and improve the processing efficiency, and when the first locking piece 104 does not exist other parts in the containing hole 1034, and the depth of the alignment gap 1011 is just right to make part of the first locking piece 104 located in the alignment gap 1011 and the other part located in the alignment hole 1022, the unlocking can be realized. However, the alignment gap 1011 in the present application can be spaced apart along the axial direction of the unlocking piece 101, and correspondingly, the number of the alignment hole 1022 and the containing hole 1034 needs to correspond to the number of the alignment gap 1011, and the number of the first locking piece 104, the second locking piece 105 and the elastic piece also needs to correspond.

[0056] Optionally, as shown in Figure 1 In combination with Figure 2 It should be noted here that the number of the alignment gap 1011 in the present application is one, which can reduce the processing difficulty and improve the processing efficiency, and when the first locking piece 104 does not exist other parts in the containing hole 1034, and the depth of the alignment gap 1011 is just right to make part of the first locking piece 104 located in the alignment gap 1011 and the other part located in the alignment hole 1022, the unlocking can be realized. However, the alignment gap 1011 in the present application can be spaced apart along the axial direction of the unlocking piece 101, and correspondingly, the number of the alignment hole 1022 and the containing hole 1034 needs to correspond to the number of the alignment gap 1011, and the number of the first locking piece 104, the second locking piece 105 and the elastic piece also needs to correspond.

[0057] It can be understood that, due to the third recess 2032 and the fourth recess 2033 formed on the second wheel body 203 in the present application, in actual operation, the second matching member 202 has only three positions to be adjusted under the action of the reversing handle 201, and for the convenience of understanding, it is set as 0 position, 1 position and 2 position, the 1 position corresponds to the third recess 2032, and the 2 position corresponds to the fourth recess 2033, that is, when the unlocking mechanism 1 is in the unlocked state, the reversing handle 201 is in the 0 position, the first transmission member 4 is located in the second recess 2031, and the second transmission member 5 abuts against the abutting portion, at this time, the reversing handle 201 can be rotated to the 1 position or the 2 position, when the reversing handle 201 is rotated to the 1 position, the second transmission member 5 enters the second recess 2031 under the action of the linkage assembly 302, at this time, the speed change control assembly 301 can perform speed change operation, and when the speed change control assembly 301 performs control, since the second transmission member 5 does not have a moving space, the reversing handle 201 can be locked at the 1 position, only when the speed change control assembly 301 returns to the initial position again, so that the second transmission member 5 has a moving space, the reversing handle 201 can be rotated again. Similarly, the process of the reversing handle 201 from the 0 position to the 2 position and the locking are the same as those from the 0 position to the 1 position, and will not be described here.

[0058] Optionally, as shown in Figure 1 In combination Figure 2 It can be understood that, due to the third recess 2032 and the fourth recess 2033 formed on the second wheel body 203 in the present application, in actual operation, the second matching member 202 has only three positions to be adjusted under the action of the reversing handle 201, and for the convenience of understanding, it is set as 0 position, 1 position and 2 position, the 1 position corresponds to the third recess 2032, and the 2 position corresponds to the fourth recess 2033, that is, when the unlocking mechanism 1 is in the unlocked state, the reversing handle 201 is in the 0 position, the first transmission member 4 is located in the second recess 2031, and the second transmission member 5 abuts against the abutting portion, at this time, the reversing handle 201 can be rotated to the 1 position or the 2 position, when the reversing handle 201 is rotated to the 1 position, the second transmission member 5 enters the second recess 2031 under the action of the linkage assembly 302, at this time, the speed change control assembly 301 can perform speed change operation, and when the speed change control assembly 301 performs control, since the second transmission member 5 does not have a moving space, the reversing handle 201 can be locked at the 1 position, only when the speed change control assembly 301 returns to the initial position again, so that the second transmission member 5 has a moving space, the reversing handle 201 can be rotated again. Similarly, the process of the reversing handle 201 from the 0 position to the 2 position and the locking are the same as those from the 0 position to the 1 position, and will not be described here.

[0059] In the present application, the position corresponding to the linkage assembly 302 on the bottom surface of the mounting panel 6 is formed with a protective shell, and part of the first connecting member 3025, the second connecting member 3026, the plug-in member 3023 and the positioning member 3021 is located in the protective shell, at the same time, the bottom of the mounting panel 6 is also provided with a partition plate 601, and the reversing mechanism 2 and the speed change mechanism 3 are arranged on the two sides of the partition plate 601, so that the setting of the protective shell can be met, and the installation of the positioning member 3021 and the plug-in member 3023 can be realized through the protective shell.

[0060] In actual installation, the linkage assembly 302 in the application further comprises a first positioning sleeve and a second positioning sleeve, which are connected with the inner wall of the protective shell, the first connecting piece 3025 and the second connecting piece 3026 are connecting shafts, the first connecting piece 3025 passes through the positioning piece 3021, the first positioning sleeve, the second positioning sleeve and the plug-in piece 3023, and the first connecting piece 3025 is rotationally connected with the first positioning sleeve and the second positioning sleeve, and the two ends of the first connecting piece 3025 are fixedly connected with the positioning piece 3021 and the plug-in piece 3023, respectively, which can realize the stable connection of the positioning piece 3021 and the plug-in piece 3023 with the protective shell, and can also enable the positioning piece 3021 and the plug-in piece 3023 to rotate relative to the protective shell.

[0061] After assembly, the positioning piece 3021 and the plug-in piece 3023 in the application have a pre-tightening force for moving the linkage part 3022 towards the second wheel body 203, and correspondingly, the pre-tightening force of the positioning piece 3021 and the plug-in piece 3023 can be increased by the second transmission member 5 arranged between the linkage part 3022 and the second wheel body 203, and the pre-tightening force can be applied to the second transmission member 5.

[0062] Preferably, the second transmission member 5 in the application is a spherical structure, when the second wheel body 203 rotates to the third recess 2032 or the fourth recess 2033, the pre-tightening force pushes the second transmission member 5 into the third recess 2032 or the fourth recess 2033, so that the pre-tightening force of the positioning piece 3021 and the plug-in piece 3023 is released to a certain extent, and the plug-in part 3024 of the plug-in piece 3023 moves away from the gear shift control assembly 301, thereby releasing the gear shift control assembly 301.

[0063] Further preferably, as shown in Figure 1 As shown in Figure 2 The gear shift control assembly 301 in the application comprises a gear shift handle 3011 and a transmission disc 3012; the transmission disc 3012 is formed with a slot 3013 corresponding to the position of the plug-in part 3024, and the gear shift handle 3011 is connected with the transmission disc 3012 to drive the transmission disc 3012 to rotate.

[0064] Through the slot 3013 formed on the transmission disc 3012, the plug-in part 3024 can be inserted into the slot 3013, so that the locking of the transmission disc 3012 is more stable.

[0065] The complete action of the multi-stage interlocking controller provided in the application is that the unlocking piece 101 is inserted into the unlocking hole 1021 to make the first locking piece 104 enter the alignment gap 1011, thereby realizing the unlocking between the core 102 and the shell 103, so that the core 102 can rotate relative to the shell 103, and the movement of the first recess 1061 is realized.

[0066] When the first recess 1061 corresponds to the first transmission member 4, the first transmission member 4 can be provided with a space for movement, so as to realize rotation of the reversing control assembly.

[0067] When the second matching member 202 is controlled to rotate by the reversing handle 201, the second wheel body 203 can be driven to rotate, so as to make the second recess 2031 dislocate with the first transmission member 4, and realize locking of the first wheel body 106. Meanwhile, the rotation of the second wheel body 203 can make the third recess 2032 or the fourth recess 2033 opposite to the second transmission member 5, and then under the driving of the positioning member 3021, the second transmission member 5 can be pushed into the third recess 2032 or the fourth recess 2033.

[0068] Since one end of the positioning member 3021 is rotationally connected with the first connecting member 3025, the other end is fixedly connected with the second connecting member 3026, and the linkage part 3022 is formed at a position close to the second connecting member 3026, the positioning member 3021 can produce a certain degree of rotation with the first connecting member 3025 as a rotation shaft.

[0069] Correspondingly, since the plug-in part 3023 is connected with the positioning member 3021 through the first connecting member 3025 and the second connecting member 3026, and the first position of the plug-in part 3023 is rotationally connected with the first connecting member 3025 and the second position is fixedly connected with the second connecting member 3026, when the positioning member 3021 produces rotation, the plug-in part 3023 can be driven to produce rotation, so that the plug-in part 3023 can be separated from the insertion slot 3013.

[0070] When the plug-in part 3024 is separated from the insertion slot 3013, the rotating disc is unlocked, and gear shifting control can be realized. When the rotating disc rotates and the insertion slot 3013 dislocates with the plug-in part 3024, since the plug-in part 3024 abuts against the disc body, the plug-in part 3023 cannot move towards the direction close to the rotating disc. Correspondingly, in this state, the second transmission member 5 cannot be separated from the third recess 2032 or the fourth recess 2033, so that when the gear shifting handle 3011 is controlled, the reversing handle 201 cannot be controlled synchronously, and the interlocking of the reversing and gear shifting actions is realized.

[0071] When the rotating disc is reset, the plug-in part 3024 can enter the insertion slot 3013 again, so as to release the second transmission member 5, and the reversing handle 201 can be rotated again to realize the reversing action.

[0072] Preferably, as shown in Figure 1 As shown in Figure 2 The multi-stage interlocking controller further comprises a first ten-thousand-rotation switch 7 and a second ten-thousand-rotation switch 8. The first ten-thousand-rotation switch 7 is connected with the unlocking mechanism 1, and the second ten-thousand-rotation switch 8 is connected with the reversing mechanism 2.

[0073] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
