[0002] With the continuous development of railway transportation, in the electric traction operation of railway trunk lines, one locomotive traction sometimes cannot meet the transportation requirements, so multiple locomotive traction is needed. The use of multiple locomotive traction can greatly increase the line's throughput capacity and improve the economic indicators of railway transportation. When multiple locomotive traction is used on the trunk line, only one driver can operate one locomotive, and the electrical lines of each locomotive are connected through multi-core cable plugs at both ends of the locomotive, so that one driver can operate multiple locomotives. We call the latter operation mode the locomotive reconnection operation. At present, a large gate reconnection position controller is set in the locomotive driver's cab. The reconnection state can be turned on by pushing the control slide button on the surface to the specified position and locking it.

[0003] However, the control slider on the existing controller has a small resistance to sliding upward, so there is a risk of accidental sliding of the control slider. In addition, it is not convenient to provide further prompts and confirmation when the control slider slides upward, which makes the switching of the gate reconnection working state lack the anti-misoperation insurance effect, and the control slider is not easy to automatically reset after sliding.

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] See also Figure 1-4 The utility model provides a limiting safety device for the reconnection position of a large gate in a driver's cab of a railway locomotive, comprising a mounting support 1, an elastic limiting mechanism is arranged above the mounting support 1, the elastic limiting mechanism comprises a spring sleeve 3, a safety slide bar 4, a knocking ball 5 and a knocking gong plate 7, the spring sleeve 3 is fixed at the upper end surface of the mounting support 1, the safety slide bar 4 is penetrated in the interior of the spring sleeve 3, the knocking ball 5 is fixed at the upper end of the safety slide bar 4, the knocking gong plate 7 is arranged in the upper area of ​​the knocking ball 5, a limiting safety mechanism is arranged at the lower end of the safety slide bar 4, the limiting safety mechanism comprises a lifting slide 10, a withdrawal slide bar 11 and a limiting stopper 12, the lifting slide 10 is fixed at the lower end of the safety slide bar 4, the limiting stopper 12 is arranged on one side of the lifting slide 10, and the withdrawal slide bar 11 is fixed at one end surface of the limiting stopper 12.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth explaining in detail that a telescopic slide plate 8 is fixed on the surface of the safety slide rod 4 inside the spring sleeve 3 , and the telescopic slide plate 8 is slidably connected in the inner cavity of the spring sleeve 3 .

[0025] Further as Figure 3 As shown, it is worth explaining in detail that a buffer spring 9 is sleeved on the portion where the safety slide rod 4 extends into the interior of the spring sleeve 3, the lower end of the buffer spring 9 is fixed on the upper end surface of the telescopic slide plate 8, and the upper end of the buffer spring 9 is fixed on the inner top wall of the spring sleeve 3.

[0026] This solution has the following working process: before use, the mounting bracket 1 is installed on the controller housing of the gate reconnection position, and the limit block 12 is fitted on the top of the controller control slide button. When the controller control slide button is used, the control slide button slides upward along the controller and lifts the limit block 12. In the process of the control slide button sliding upward, it is necessary to overcome the elastic resistance generated by the safety slide bar 4 extending and contracting inside the spring sleeve 3 and squeezing the buffer spring 9. In this way, the elastic resistance is applied without affecting the lifting of the control slide button to effectively provide an anti-accidental touch safety function. When the lifting slide 10 rises to the bottom of the mounting bracket 1, the upward sliding operation of the control slide button is restricted. In this process, the safety slide bar 4 rises to the limit position and drives the knocking ball 5 to knock the gong plate 7 to issue a prompt sound. The prompt effect before the control slide button slides to the last section can further provide an insurance confirmation function.

[0027] According to the above working process, it can be known that: in the process of the control slide button sliding upward, it is necessary to overcome the elastic resistance generated by the safety slide rod 4 extending and contracting inside the spring sleeve 3 and squeezing the buffer spring 9. In this way, the elastic resistance is applied without affecting the lifting of the control slide button to effectively provide an anti-accidental touch safety function. The safety slide rod 4 rises to the extreme position and drives the knocking ball 5 to knock the gong plate 7 to issue a prompt sound. The prompt effect before the control slide button slides to the final section can further provide a safety confirmation function.

[0028] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that a support frame 6 is arranged between the gong-struck plate 7 and the spring sleeve 3, the upper end of the support frame 6 is fixed to the side of the gong-struck plate 7, and the lower end of the support frame 6 is fixed to the upper end surface of the spring sleeve 3.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that one end of the safety slide rod 4 slides through the upper end surface of the mounting support 1, and a buffer space is provided between the striking ball 5 and the gong plate 7 to be struck.

When the control slide button needs to continue sliding when it runs to the confirmation section, the limit stop block 12 is pulled outward from the lifting slide 10, driving the pull-out slide 11 to slide along the lifting slide 10 and opening the continuous operation space of the control slide button. The action of the limit stop block 12 pulling out the pull-out slide 11 and opening the end stroke of the control slide button is an operation for further insurance confirmation. Finally, after the control slide button slides to the end, it is locked by itself through its own locking mechanism and achieves the purpose of switching the gate to the reconnection position.

[0032] Further as Figure 1 As shown, it is worth explaining in detail that both ends of the mounting support 1 are fixed with mounting holes 2, and the mounting support 1 is fixed on the controller housing at the gate reconnection position.

[0033] In summary: in the process of the control slide button sliding upward, it is necessary to overcome the elastic resistance generated by the expansion and contraction of the safety slide rod 4 inside the spring sleeve 3 and the squeezing of the buffer spring 9. In this way, the elastic resistance is applied without affecting the lifting of the control slide button to effectively provide an anti-accidental touch safety function. The safety slide rod 4 rises to the extreme position and drives the knocking ball 5 to knock the gong board 7 to make a prompt sound. The prompt effect before the control slide button slides to the last section can further provide an insurance confirmation effect; when the control slide button runs to the confirmation section and needs to continue sliding, the pull-out slide 11 slides along the lifting slide 10 and opens the continuous operation space of the control slide button. The action of pulling out the pull-out slide 11 and opening the end stroke of the control slide button by the limit block 12 is a further insurance confirmation operation.
