Description

Technical Field

[0001] This utility model belongs to the technical field of rail transit safety devices, specifically relating to a control handle mechanism for a driver controller. Background Technology

[0002] The driver controller is used on locomotives in railways, subways, and high-speed trains. It serves as the master electrical control for traction, braking, and direction, allowing the locomotive driver to operate it. Currently, because the operation of the driver controller is relatively monotonous and simple, drivers are prone to fatigue, posing significant safety hazards to locomotive operation.

[0003] To prevent driver fatigue, modern locomotives are equipped with a signal collection device. According to a pre-programmed sequence, the driver's controller must send a safety signal to the device within a specified time. If the device does not receive the signal within the specified time, the program determines that the driver is fatigued and immediately issues a warning sound. The warning switch on the driver's controller is the electrical device that allows the driver to send a safety signal to the signal collection device.

[0004] However, most operating handles on the market currently suffer from the following two prominent problems: 1) The handle wheel of the operating handle is separated from the alert switch that transmits the safety electrical signal. This means that when the operating handle is turned to its extreme position, there may be a certain degree of deviation between it and the closing button of the alert switch, causing unreliable closure of the alert switch; 2) During locomotive operation, the locomotive driver needs to operate the operating handle at any time. To facilitate the driver's periodic pressing of the closing button of the alert switch to transmit the safety electrical signal, a button lever or other transmission components for direct hand pressing are usually integrated into the operating handle. This allows the driver to press the closing button on the alert switch by pressing the button lever. However, this also leads to frequent accidental pressing of the button lever on the operating handle, causing unnecessary high-frequency opening and closing of related transmission components such as the return spring and the closing button of the alert switch, accelerating fatigue damage and reducing the reliability of the safety electrical signal transmission. Furthermore, the above pressing method cannot detect when the driver is in a semi-sleep state (the brain has entered a light sleep, but the hand can still perform simple repetitive mechanical pressing actions), posing a certain risk of missed fatigue detection. Utility Model Content

[0005] The purpose of this invention is to provide a control handle mechanism for a driver controller, which solves the problem of low reliability in the prior art where a safety electrical signal is emitted by pressing a warning switch through the control handle mechanism.

[0006] The technical solution adopted by this utility model is as follows: a control handle mechanism for a driver controller, including a handle wheel, a support cylinder and a support rod fixedly arranged side by side in the thickness direction of the side wall of the handle wheel, the top ends of the support cylinder and the support rod are connected to a handle box seat located above the handle wheel, the handle box seat has an opening at the top and a handle box cover is rotatably connected to the opening, the top end of the support rod is provided with an anti-accidental contact component that abuts against the handle box cover, a pressure rod with its top end extending upward and abutting against the handle box cover is coaxially slidably fitted inside the support cylinder, the bottom end of the pressure rod extends downward and passes through the handle wheel to below it, and an alarm switch is fixedly connected to the bottom end of the handle wheel corresponding to the pressure rod.

[0007] The feature of this utility model is that,

[0008] The anti-accidental touch component includes a receiving groove at the top of the support rod and communicating with the inside of the handle box. A top pin that extends upward and abuts against the handle box cover is coaxially slidably fitted in the receiving groove. A longitudinal compression spring II is connected between the bottom end of the top pin and the bottom of the receiving groove. The shaft of the top pin located in the handle box has a through hole that extends from left to right. A pin that extends outward through the handle box is slidably fitted in the hole. A slot with a top opening is opened on the pin near the hole.

[0009] Inside the handle housing, on both sides outside the card hole, there are pin seats that pass through the pin. On the inner side of the end of the pin that passes through the handle housing, there is a stop pin II fixed radially. A transverse compression spring sleeved on the outside of the pin is provided between the stop pin II and the adjacent pin seat.

[0010] The handle box cover has a groove of a corresponding shape at the position of the top pin.

[0011] A stop pin I is fixed radially at the top of the pressure rod, and a longitudinal compression spring I is sleeved on the outside of the pressure rod between the stop pin I and the bottom of the handle box seat.

[0012] The bottom of the handle wheel is cut flat and a notch is provided corresponding to the position where the pressure rod extends. The alarm switch body is fixedly connected to the bottom plane of the handle wheel on both sides of the notch. The alarm switch button is located inside the notch and directly opposite the bottom of the pressure rod.

[0013] A pressure plate is coaxially fixed to the bottom end of the pressure rod.

[0014] The upper opening of the handle box base slopes downward and extends to the rear end. A rotating shaft parallel to the axis of the handle wheel is fixed between the two sides of the rear end of the handle box base. The handle box cover is sloping and its bottom end is rotated and sleeved outside the rotating shaft. The outer top of the handle box cover is not lower than the top height of the handle box base.

[0015] The beneficial effects of this utility model are as follows: This utility model is used for the operating handle mechanism of the driver controller. The handle wheel and the alert switch are integrated into one design. When the handle wheel rotates, the relative position of the pressure rod and the alert switch remains fixed. Even when rotated to the extreme position, the alert switch can still be reliably closed. Furthermore, by setting an anti-accidental contact component, the driver's normal driving operation is prevented from frequently pressing the pressure rod and damaging the relevant components of the alert switch. In addition to preventing accidental contact, the anti-accidental contact component can also force the driver to concentrate on the operation of the operating handle, avoiding perfunctory pressing that causes the alert switch to fail to play a substantial reminder role in keeping the driver's attention. Thus, the reliability of the safety electrical signal is improved in multiple ways. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] This utility model provides a control handle mechanism for a driver controller, such as... Figures 1 to 6 As shown, the device includes a handle wheel 1. A support cylinder 2 and a support rod 3 are fixed side-by-side along the thickness of the side wall of the handle wheel 1. The top ends of the support cylinder 2 and the support rod 3 are connected to a handle housing 4 located above the handle wheel 1. The handle housing 4 has an opening at the top, and a handle housing cover 5 is rotatably connected to the opening. The top end of the support rod 3 is provided with an anti-accidental contact component that abuts against the handle housing cover 5. A pressure rod 6 with its top end extending upward and abutting against the handle housing cover 5 is coaxially slidably fitted inside the support cylinder 2. A stop pin I 18 is fixed radially at the top end of the pressure rod 6. A longitudinal compression spring I 19 is sleeved on the pressure rod 6 between the stop pin I 18 and the bottom of the handle housing 4. The bottom end of the pressure rod 6 extends downward and passes through the handle wheel 1 to its lower end. An alarm switch 7 is fixedly connected below the bottom end of the handle wheel 1 corresponding to the pressure rod 6.

[0026] In the above manner, the operating handle mechanism of the driver controller of this utility model is integrated with the handle wheel 1 and the alert switch 7. When the handle wheel 1 rotates, the alert switch 7 rotates synchronously. The relative position of the pressure rod and the alert switch 7 is always fixed. The closing button of the alert switch 7 is always aligned with the bottom end of the pressure rod 6. In this way, even if it is rotated to the extreme position, the alert switch 7 can be reliably closed.

[0027] During locomotive operation, the driver needs to operate the control lever at all times, requiring the hand to always hold the lever in a state of operation or readiness to operate. This inevitably leads to frequent accidental pressing of the lever cover 5. If not restricted, the lever 6 will press down on the warning switch 7, which will inevitably cause fatigue damage to the relevant components over time, thus failing to provide a safety signal. This invention prevents accidental pressing by setting an anti-accidental touch component, preventing the driver from pressing the lever cover 5 while holding the lever, thus avoiding frequent accidental pressing of the lever 6 during normal driving operations and preventing damage to the warning switch 7 and related components. However, when it is necessary to press the handle cover 5 to send a safety signal, the driver only needs to press the pin 12 extending from one side of the handle base 4 with his thumb to unlock the anti-accidental touch component. After unlocking, the palm can press the handle cover 5 normally to press the closed button on the alert switch 7, thereby sending a safety signal. In practice, locomotive drivers often lose focus after driving for a long time. Although their palms appear to be holding the handle, their attention is not focused on the operation. Since pressing the alert switch only requires a downward action, a mechanical or perfunctory pressing action can also send a safety signal, but this does not actually remind the driver to keep their attention. The anti-accidental touch component of this utility model adds an unlocking operation when pressing the alert switch. By appropriately adding an operation action, the driver's attention is forcibly drawn back to the operation of the handle, thereby playing a substantial reminder role and ultimately improving the reliability of the safety signal.

[0028] Example 2

[0029] This utility model provides a control handle mechanism for a driver controller, such as... Figures 1 to 6 As shown, the device includes a handle wheel 1. A support cylinder 2 and a support rod 3 are fixed side-by-side along the thickness of the side wall of the handle wheel 1. The top ends of the support cylinder 2 and the support rod 3 are connected to a handle housing 4 located above the handle wheel 1. The handle housing 4 has an opening at the top, and a handle housing cover 5 is rotatably connected to the opening. The top end of the support rod 3 is provided with an anti-accidental contact component that abuts against the handle housing cover 5. A pressure rod 6 with its top end extending upward and abutting against the handle housing cover 5 is coaxially slidably fitted inside the support cylinder 2. A stop pin I 18 is fixed radially at the top end of the pressure rod 6. A longitudinal compression spring I 19 is sleeved on the pressure rod 6 between the stop pin I 18 and the bottom of the handle housing 4. The bottom end of the pressure rod 6 extends downward and passes through the handle wheel 1 to its lower end. An alarm switch 7 is fixedly connected below the bottom end of the handle wheel 1 corresponding to the pressure rod 6.

[0030] The anti-accidental touch component includes a receiving groove 8 located at the top of the support rod 3 and communicating with the inside of the handle box 4. A top pin 9, which extends upward and abuts against the handle box cover 5, is coaxially slidably fitted within the receiving groove 8. A pressure groove 17, with a corresponding shape, is provided on the handle box cover 5 at the position corresponding to the top pin 9. A longitudinal compression spring II 10 is connected between the bottom end of the top pin 9 and the bottom of the receiving groove 8. A through-hole 11 is provided on the shaft of the top pin 9 located inside the handle box 4. A pin 12, with one end extending outward through the handle box 4, is slidably fitted within the pin 11. A slot 13 with a top opening is provided on the pin 12 near the pin 11.

[0031] When the anti-accidental touch component is locked, the top pin 9 is pressed into the pressure groove 17, and the pin 12 in the locking hole 11 fixes the upper and lower positions of the top pin 9. Under the action of the top pin 9, even if the handle cover 5 is pressed, the handle cover 5 will not rotate downward, thus preventing the pressure rod 6 from being pressed down. When unlocking is required, the pin 12 is pressed inward so that the locking groove 13 aligns with the top pin 9. The top pin 9 loses the upper and lower restriction of the pin 12. At this time, after pressing the handle cover 5, the top pin 9 is pressed down along the receiving slide groove 8 on the support rod 3. At the same time, the longitudinal compression spring II 10 and the longitudinal compression spring I 19 are compressed, and the pressure rod 6 is also pressed down. Pressing down the handle cover 5 causes it to slide downwards along the support cylinder 2 and press the closed button on the alert switch 7, which sends out a safety electrical signal. When it is necessary to restore the lock, the palm releases the handle cover 5, the longitudinal compression spring II 10 unfolds and lifts the top pin 9, and the top pin 9 lifts the handle cover 5. At the same time, under the action of the longitudinal compression spring I 19, the stop pin I 18 drives the pressure rod 6 to return upward and disengage from the alert switch 7. Then, the pin 12 is pulled outwards, so that the slot 13 is disengaged from the top pin 9. The top pin 9 is restricted from moving up and down by the unnotched position of the pin 12, thus restoring the lock.

[0032] Example 3

[0033] This utility model provides a control handle mechanism for a driver controller, such as... Figures 1 to 6 As shown, the device includes a handle wheel 1. A support cylinder 2 and a support rod 3 are fixed side-by-side along the thickness of the side wall of the handle wheel 1. The top ends of the support cylinder 2 and the support rod 3 are connected to a handle housing 4 located above the handle wheel 1. The handle housing 4 has an opening at the top, and a handle housing cover 5 is rotatably connected to the opening. The top end of the support rod 3 is provided with an anti-accidental contact component that abuts against the handle housing cover 5. A pressure rod 6 with its top end extending upward and abutting against the handle housing cover 5 is coaxially slidably fitted inside the support cylinder 2. A stop pin I 18 is fixed radially at the top end of the pressure rod 6. A longitudinal compression spring I 19 is sleeved on the pressure rod 6 between the stop pin I 18 and the bottom of the handle housing 4. The bottom end of the pressure rod 6 extends downward and passes through the handle wheel 1 to its lower end. An alarm switch 7 is fixedly connected below the bottom end of the handle wheel 1 corresponding to the pressure rod 6.

[0034] The anti-accidental touch component includes a receiving groove 8 located at the top of the support rod 3 and communicating with the inside of the handle box 4. A top pin 9, which extends upward and abuts against the handle box cover 5, is coaxially slidably fitted within the receiving groove 8. A pressure groove 17, with a corresponding shape, is provided on the handle box cover 5 at the position corresponding to the top pin 9. A longitudinal compression spring II 10 is connected between the bottom end of the top pin 9 and the bottom of the receiving groove 8. A through-hole 11 is provided on the shaft of the top pin 9 located inside the handle box 4. A pin 12, with one end extending outward through the handle box 4, is slidably fitted within the pin 11. A slot 13 with a top opening is provided on the pin 12 near the pin 11. Inside the handle box 4, on both sides outside the card hole 11, there are fixed pin seats 14 that pass through the pin 12. On the inner side of the end of the pin 12 that passes through the handle box 4, there is a stop pin II 15 fixed radially. A transverse compression spring 16 sleeved on the outside of the pin 12 is provided between the stop pin II 15 and the adjacent pin seat 14.

[0035] When the anti-accidental touch component is locked, the top pin 9 is pressed against the pressure groove 17, and the pin 12 in the locking hole 11 fixes the upper and lower positions of the top pin 9. Under the action of the top pin 9, even if the handle cover 5 is pressed, the handle cover 5 will not rotate downwards, thus preventing the pressure rod 6 from being pressed down. When unlocking is required, the pin 12 is pressed inwards along the pin seat 14 so that the locking groove 13 aligns with the top pin 9. At the same time, the transverse compression spring 16 between the stop pin II 15 and the pin seat 14 is compressed, and the top pin 9 loses the upper and lower restriction of the pin 12. At this time, after pressing the handle cover 5, the top pin 9 is pressed down along the receiving slide groove 8 on the support rod 3, and at the same time, the longitudinal compression spring II 10 and the longitudinal compression spring I 19 are compressed. The lever 6 is also pressed down by the handle cover 5, thus sliding down along the support cylinder 2 and pressing the closed button on the alert switch 7, causing it to emit a safety electrical signal; when it is necessary to restore the lock, the palm releases the handle cover 5, the longitudinal compression spring II 10 unfolds and lifts the top pin 9, the top pin 9 lifts the handle cover 5, and at the same time, under the action of the longitudinal compression spring I 19, the stop pin I 18 drives the lever 6 to return to the upward and disengage from the alert switch 7. Then, the pressure on the pin 12 is released, the transverse compression spring 16 unfolds and pushes the pin 12 outward, so that the slot 13 position disengages from the top pin 9. Then, the top pin 9 is restricted to move up and down by the unnotched position of the pin 12, thus restoring the lock.

[0036] Example 4

[0037] This utility model provides a control handle mechanism for a driver controller, such as... Figures 1 to 6 As shown, the device includes a handle wheel 1. A support cylinder 2 and a support rod 3 are fixed side-by-side along the thickness of the side wall of the handle wheel 1. The top ends of the support cylinder 2 and the support rod 3 are connected to a handle housing 4 located above the handle wheel 1. The handle housing 4 has an opening at the top, and a handle housing cover 5 is rotatably connected to the opening. The top end of the support rod 3 is provided with an anti-accidental contact component that abuts against the handle housing cover 5. A pressure rod 6 with its top end extending upward and abutting against the handle housing cover 5 is coaxially slidably fitted inside the support cylinder 2. A stop pin I 18 is fixed radially at the top end of the pressure rod 6. A longitudinal compression spring I 19 is sleeved on the pressure rod 6 between the stop pin I 18 and the bottom of the handle housing 4. The bottom end of the pressure rod 6 extends downward and passes through the handle wheel 1 to its lower end. An alarm switch 7 is fixedly connected below the bottom end of the handle wheel 1 corresponding to the pressure rod 6.

[0038] To make the structure of this utility model more compact and occupy less space in the limited operating mechanism, the bottom end of the handle wheel 1 is cut flat and a notch is opened corresponding to the position where the pressure rod extends. The body of the alert switch 7 is fixedly connected to the bottom plane of the handle wheel 1 outside the notch on both sides. The button of the alert switch 7 is located inside the notch and directly opposite the bottom end of the pressure rod 6. In this way, even if the handle wheel 1 and the alert switch 7 are integrated into one design, the overall space occupied is close to that of a complete handle wheel 1. In addition, a pressure plate 20 can be coaxially fixed to the bottom end of the pressure rod 6 to ensure that the smaller pressure rod 6 can reliably press the button of the alert switch 7.

[0039] Example 5

[0040] This utility model provides a control handle mechanism for a driver controller, such as... Figures 1 to 6 As shown, the device includes a handle wheel 1. A support cylinder 2 and a support rod 3 are fixed side-by-side along the thickness of the side wall of the handle wheel 1. The top ends of the support cylinder 2 and the support rod 3 are connected to a handle housing 4 located above the handle wheel 1. The handle housing 4 has an opening at the top, and a handle housing cover 5 is rotatably connected to the opening. The top end of the support rod 3 is provided with an anti-accidental contact component that abuts against the handle housing cover 5. A pressure rod 6 with its top end extending upward and abutting against the handle housing cover 5 is coaxially slidably fitted inside the support cylinder 2. A stop pin I 18 is fixed radially at the top end of the pressure rod 6. A longitudinal compression spring I 19 is sleeved on the pressure rod 6 between the stop pin I 18 and the bottom of the handle housing 4. The bottom end of the pressure rod 6 extends downward and passes through the handle wheel 1 to its lower end. An alarm switch 7 is fixedly connected below the bottom end of the handle wheel 1 corresponding to the pressure rod 6.

[0041] To make the driver more comfortable to hold the device for extended periods during operation, the handle box 4 is designed with an ergonomically curved grip surface. The upper opening of the handle box 4 slopes downward and extends to the rear end. A rotating shaft 21 parallel to the axis of the handle wheel 1 is fixed between the two rear sides of the handle box 4. The handle box cover 5 is sloping and its bottom end is rotated and sleeved on the rotating shaft 21. The top of the handle box cover 5 is not lower than the top of the handle box 4. This allows the pressure lever 6 to be pressed down after the anti-accidental touch component is unlocked and the handle box cover 5 is pressed flat to the top of the handle box 4.

[0042] Example 6

[0043] This utility model provides a control handle mechanism for a driver controller, such as... Figures 1 to 6 As shown, during installation, the central shaft 22 of the handle wheel 1 is connected to the controller. The gear 23 meshes with other transmission structures to transmit the locomotive driver's operating actions during locomotive driving. When a safety electrical signal needs to be issued, the anti-accidental contact component is first released by pressing the pin 12 protruding from one side of the handle box seat 4 with the thumb to release the anti-accidental contact component from the handle box cover 5. Then, the handle box cover 5 is pressed down to make the pressure rod 6 press down the warning switch 7. After completion, the palm releases the handle box cover 5, the pressure rod 6 returns to the upward position to release the warning switch 7, and the thumb is released to restore the lock of the anti-accidental contact component.
