Description

Technical Field

[0001] The utility model relates to the technical field of locomotive electrical equipment, in particular to a driver control handle with an anti-slip function. Background Art

[0002] The driver controller is a control device for railway locomotives, EMUs and industrial automation. As the main command electrical appliance for locomotive reversing and speed regulation, the driver controller mainly has two operating handles: one is called the reversing handle, and the other is called the control handle, also called the main handle. The main handle has levels of 0 and levels above the asterisk position. The main handle involved in this patent is the main handle.

[0003] The existing locomotive teaching driver controller, such as Chinese Patent No.: CN202020250060.X; the new teaching driver controller can simulate the operation of this type of real car driver controller, and the gear handle and the steering handle also have an interlocking function, which can meet the needs of teaching and other uses.

[0004] In modern railway locomotive design, in order to prevent the driver's control handle (such as the main controller) from quickly passing or "slipping" from one gear to another during operation (such as jumping directly from the forward gear back to the neutral gear / star position without going through the appropriate deceleration stage), a series of measures and technologies are usually taken to ensure accurate and safe gear shifting control. The following are some mechanisms to prevent such problems from occurring:

[0005] 1. Mechanical limit design;

[0006] 2. Electronic control logic;

[0007] 3. Buffering and damping design;

[0008] 4. Driver operation training;

[0009] Still, any mechanical system can fail or malfunction, but modern locomotive control systems are usually able to prevent the control handle from slipping past the star position when well maintained and properly operated. If improper shifting occurs frequently, equipment inspection or adjustment may be necessary to ensure proper operation of the system.

[0010] The above patented technical solution also has the following problems: long-term use of the driver controller may lead to poor gear meshing when operating from the 0 position to the star position, and the problem of directly skipping the star position and returning to the 0 position when returning from the star position to the star position, which may eventually lead to:

[0011] Sudden power interruption, 2. Difference in braking response, 3. Control system alarm, 4. Energy consumption or thermal management issues, 5. Impact on the transmission system:

[0012] The first reason is that gear meshing will eventually have a short lifespan;

[0013] The second problem is that when the driver operates the handle through the star position or returns to the 0 position, there will be no sound or operating feel to remind the driver that the limit has been reached, which will indirectly lead to excessive force to cross the star position and return to the 0 position.

[0014] Therefore, it is necessary to improve the current locomotive electrical driver controller. Summary of the invention

[0015] The utility model mainly provides a device which can remind the driver to arrive at the star position.

[0016] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a driver control handle with an anti-slip function, comprising a control handle body, a grip connected to the top of the control handle body, a button connected to the top of the grip, a rotating ring connected to the outer surface of one side of the control handle body, a sleeve connected to the outer surface of one side of the rotating ring, a star position mark connected to the top center of the sleeve, a notch is provided on the side of the sleeve close to the control handle body, a spring is arranged inside the notch, a push block is connected to one side of the spring, a ball is connected to one side of the push block, and a card slot is provided on the side of the control handle body close to the sleeve.

[0017] Preferably, the control handle body is rotatably connected to the casing via a rotating ring, the button is arranged at the top center of the grip, and the rotating ring can facilitate the rotation between the control handle body and the casing.

[0018] Preferably, the push block forms an elastic structure through the notch and the spring, and the position and size of the ball match the position and size of the slot. When the position of the ball matches the slot, the ball will be pushed into the slot by the spring to act as a resistance to prevent the control handle body from sliding over the star position when being pushed.

[0019] Preferably, the ball and the slot form a snap-fit ​​connection, and the ball has a semicircular shape. The semicircular design allows the driver to use a slightly greater force to push the ball down, so that traction above the star position can be performed.

[0020] Preferably, the outer surface of the push block fits with the inner surface wall of the notch, and the push block can improve the stability of the spring when it contracts into the notch.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] 1. In the utility model, when the driver grasps the grip to adjust the gear position of the control handle body and reaches the star position, the ball and the slot will engage and make a meshing sound, and increase the resistance, reminding the driver that the star position has been reached. When the driver wants to tow again, the driver needs to use a little more force to push the grip so that the ball can be squeezed down, so that towing above the star position can be carried out, avoiding the problem of the existing control handle body sliding easily when pushed, and improving the overall practicality and service life.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0031] See also Figure 1-5The utility model provides a technical solution: a driver control handle with an anti-slip function, comprising a control handle body 1, a grip 2 connected to the top of the control handle body 1, a button 3 connected to the top of the grip 2, a rotating ring 4 connected to the outer surface of one side of the control handle body 1, a shell 5 connected to the outer surface of one side of the rotating ring 4, a star position mark 6 connected to the top center of the shell 5, a notch 7 is provided on the side of the shell 5 close to the control handle body 1, a spring 8 is arranged inside the notch 7, a push block 9 is connected to one side of the spring 8, a ball 10 is connected to one side of the push block 9, and a card slot 11 is provided on the side of the control handle body 1 close to the shell 5.

[0032] like Figure 1 and Figure 2 As shown, the control handle body 1 is rotatably connected to the casing 5 via a rotating ring 4, and the button 3 is arranged at the top center of the grip 2. The rotating ring 4 can facilitate the rotation between the control handle body 1 and the casing 5.

[0033] like Figure 5 As shown, the push block 9 forms an elastic structure through the notch 7 and the spring 8, and the position and size of the ball 10 match the position and size of the slot 11. When the position of the ball 10 matches the slot 11, the ball 10 will be pushed into the slot 11 by the spring 8 to act as a resistance to prevent the control handle body 1 from sliding over the star position when being pushed.

[0034] like Figure 2 and Figure 5 As shown, the ball 10 and the slot 11 form a snap-fit ​​connection. The ball 10 is semicircular in shape. The semicircular design allows the driver to use a little more force to push the ball 10 down, so that traction above the star position can be performed.

[0035] like Figure 5 As shown, the outer surface of the push block 9 is in contact with the inner surface wall of the slot 7 , and the push block 9 can improve the stability of the spring 8 when it contracts into the slot 7 .

[0036] The usage and working principle of the device are as follows: when the driver is towing, the button 3 in the side slot 11 of the control handle body 1 drops to unlock its locked state. When the driver's button 3 moves to the asterisk position, the spring 8 will push the ball 10 through the push block 9, which will also generate a certain friction with the control handle body 1, and the resistance generated by the meshing of the gear and the convex groove under the original control handle body 1 will produce a larger friction force together, so as to increase the hand feel and remind the driver that it is moving towards the asterisk position at this time, and prevent the driver from using too much force due to lack of a strong hand feel, and directly pushing past the asterisk position. Most of the wear and tear is caused because sometimes the driver reaches the asterisk position, but because he does not pay attention or the hand feel is not good, there is no such reminder, which causes the driver to push the handle directly past the asterisk position. The above scheme increases the hand feel. The following is the second aspect, and the driver When the control handle body 1 reaches the asterisk position, the ball 10 in the inner groove on the side of the control handle body 1 and the slot 11 will make an engagement sound, which is similar to the sound made by the elastic convex ball of an old-fashioned umbrella from the time the umbrella is opened to the time when the umbrella is half opened. At this time, the driver is reminded that the asterisk position has been reached. Please stay for one second before towing. At this time, the engagement between the ball 10 and the slot 11 will also play a limiting role. When the driver wants to tow again, the driver needs to use a little more force. After pushing, the ball 10 is squeezed down, so that towing above the asterisk position can be carried out. When the driver wants to cancel the traction from level 12, he must pull the handle back to the zero position. In the process of pulling back, when it reaches the asterisk position, the ball 10 of the driver's control handle will generate resistance with the slot 11 to achieve a limiting effect. Similarly, after staying at the asterisk position for one second, use a little more force to pull it back to the zero position.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
