Description

Technical Field

[0001] The utility model relates to a working mechanism conversion device of a hydraulic transmission box of a diesel locomotive, which can realize the rapid conversion of gears of different working modes of the diesel locomotive and belongs to the technical field of diesel locomotives. Background Art

[0002] The function of the hydraulic transmission box is to transfer the power of the diesel engine to the locomotive axle, and transform the external characteristics of the diesel engine into the ideal traction performance of the locomotive. The transmission box is equipped with a working condition mechanism. By operating the conversion device of the working condition mechanism, the diesel locomotive can be switched to shunting condition or small operation condition, so that the diesel locomotive enters different operating modes.

[0003] GK1C locomotive hydraulic transmission case working mechanism conversion device Figure 1-2 As shown, it includes a working condition adjusting rod 5, a working condition handle 6 and an adjusting rod locking mechanism, wherein the adjusting rod locking mechanism includes a supporting plate 7, an arc-shaped positioning plate 1, a positioning pin 3 and a compression spring 8. The lower end of the working condition adjusting rod 5 is connected to the hydraulic transmission box 4, and the upper end is connected to the working condition handle 6. The supporting plate 7 is fixed in the middle of the working condition adjusting rod 5. A pull plate is provided at the upper end of the positioning pin 3, and the lower end slides through the supporting plate 7 and the compression spring 8 in sequence. The upper end of the compression spring 8 supports the lower surface of the supporting plate 7, and the lower end supports the boss on the side wall of the positioning pin 3. The arc-shaped positioning plate 1 is located below the supporting plate 7. One end of the arc-shaped positioning plate 1 is fixedly connected to the hydraulic transmission box 4. Three positioning holes 2 corresponding to the positioning pin 3 are provided on the arc-shaped positioning plate 1. When the working condition adjusting rod 5 is rotated to make the positioning pin 3 inserted into the three positioning holes 2 respectively, the diesel locomotive is switched to the shunting working condition, the neutral working condition and the small operation working condition respectively. When it is necessary to switch the operation mode (working condition), first lift the positioning pin 3 to separate it from the arc positioning plate 1, and then rotate the rotating working condition adjustment rod 5 to a certain angle by pushing and pulling the working condition handle 6, so that the positioning pin 3 is inserted into another positioning hole 2 to complete the switching of the operation mode. In actual operation, the operator can only lift and pull the positioning pin 3 with one hand and push and pull the working condition handle 6 with the other hand. Due to the large rotation torque of the working condition adjustment rod 5, it is difficult to push and pull the working condition handle 6 with one hand, and the hydraulic transmission case working condition mechanism conversion device of the GK1C locomotive is installed in a small space, which is very inconvenient to operate, further increasing the difficulty of switching the operation mode and seriously affecting the operation efficiency. Therefore, it is very necessary to design an easy-to-operate diesel locomotive hydraulic transmission case working condition mechanism conversion device. Utility Model Content

[0019] In view of the problems existing in the prior art, the utility model provides a device for converting the working mechanism of the hydraulic transmission box of a diesel locomotive. The device has strong practicality and can ensure that the operator can quickly complete the conversion of the working mechanism of the transmission box, thereby improving working efficiency, improving the reliability of the equipment, and effectively ensuring the stable operation of the equipment.

[0020] See also Figure 1-4 The utility model mainly includes a working condition adjustment rod 5, a working condition handle 6, an adjustment rod locking mechanism and an automatic unlocking mechanism, wherein the adjustment rod locking mechanism is the same as the traditional working condition mechanism conversion device, including a support plate 7, an arc-shaped positioning plate 1, a positioning pin 3 and a compression spring 8; the automatic unlocking mechanism is an added part, including a lifting handle 11, a lifting rope 10 and a buckle 9.

[0021] The support plate 7 is fixed to the middle part of the working condition adjustment rod 5. A pull plate is provided at the upper end of the positioning pin 3, and the lower end slides through the support plate 7 and the compression spring 8 in sequence. The upper end of the compression spring 8 presses against the lower surface of the support plate 7, and the lower end presses against the boss on the side wall of the positioning pin 3. The arc-shaped positioning plate 1 is located below the support plate 7. One end of the arc-shaped positioning plate 1 is fixedly connected to the hydraulic transmission box 4. Three positioning holes 2 corresponding to the positioning pin 3 are provided on the arc-shaped positioning plate 1, and the buckle 9 is connected to the positioning pin 3.

[0022] The lifting handle 11 is located above the working handle 6, and a bracket 12 is installed on the upper part of the working handle 6. The middle part of the lifting handle 11 is rotatably connected to the bracket 12, and the lifting rope 10 slides through the vertical through hole on the working handle 6. The lower end of the lifting rope 10 is connected to the positioning pin 3 in the adjustment rod locking mechanism through the buckle 9, and the upper end is connected to the end of the lifting handle 11 close to the working condition adjustment rod 5. The lifting handle 11 forms a lever for pulling the lifting rope 10 upward.

[0023] The buckle 9 includes two hooks 9-1, a horizontal shaft 9-2 and a tension spring 9-3. The two hooks 9-1 are symmetrically arranged on both sides of the positioning pin 3. The hook heads at the lower ends of the two hooks 9-1 hook the pull plate at the upper end of the positioning pin 3. The upper ends of the hook handles of the two hooks 9-1 are rotatably connected through the horizontal shaft 9-2. The middle parts of the hook handles are connected through the tension spring 9-3.

[0025] The method of using the utility model is as follows:

[0026] When it is necessary to switch the operation mode (working condition), first use the two hooks 9-1 of the buckle 9 to hook the pull plate at the upper end of the positioning pin 3, then hold the working condition handle 6 and the end of the lifting handle 11 away from the working condition adjustment rod 5 by hand at the same time, and rotate the lifting handle 11 around the bracket 12. The end of the lifting handle 11 close to the working condition adjustment rod 5 is tilted upward, and the buckle 9 is pulled upward by the lifting rope 10, so that the positioning pin 3 rises together with the buckle 9. When the positioning pin 3 is pulled out of the positioning hole 2, the rotating working condition adjustment rod 5 is rotated to a certain angle by pushing and pulling the working condition handle 6, and finally the lifting handle 11 is released, and the lifting rope 10 no longer pulls the buckle 9 upward. The positioning pin 3 is automatically inserted into another positioning hole 2 under the elastic force of the compression spring 8, and the switching of the operation mode is completed. Since the entire switching process does not require the positioning pin 3 to be operated separately, the difficulty of switching the operation mode is greatly reduced and the work efficiency is improved.

[0027] After the operation mode is switched, the buckle 9 can be removed from the positioning pin 3 to prevent malfunction.
