As shown in fig. 1 to 4, in one embodiment, an auxiliary detaching device includes: slide mechanism 100, lifting mechanism 200 and wrench mechanism 300, slide mechanism 100 is used for corresponding with the piston connecting rod 10 of hoist and mount in the locomotive (the tip of meaning piston connecting rod 10 can move towards the slide region of slide mechanism 100), just lifting mechanism 200 is movably installed on lifting mechanism 200, lifting mechanism 200 through the lift adjustment with the tip of piston connecting rod 10 is inconsistent, wrench mechanism 300 is installed on lifting mechanism 200, just wrench mechanism 300 with the cooperation is connected to the installed part 12 of piston connecting rod 10.

First, the piston rod 10 is installed inside the motorcycle and reciprocally rotated or moved. The disassembly of the piston rod 10 is concentrated on the end of the piston rod 10, that is, the connection at the fastening part needs to be released when the piston rod 10 is disassembled, that is, the mounting part 12 at the end of the piston rod 10 needs to be disassembled.

When the auxiliary detaching device is used, the sliding mechanism 100 is first installed inside the locomotive, for example: the sliding mechanism 100 may be placed in a position corresponding to the piston rod 10 in the locomotive, and then the sliding mechanism 100 may directly use its own weight to achieve fixation at a specific position. The sliding mechanism 100 may be secured against other structures within the locomotive, such as the interior walls of the locomotive or the anchor bolts within the locomotive. At this time, the lifting mechanism 200 is installed on the sliding mechanism 100, and the lifting mechanism 200 can move on the sliding mechanism 100, that is, the lifting mechanism 200 moves on the sliding mechanism 100 according to the specific position of the piston rod 10 until the lifting mechanism 200 corresponds to the end of the piston rod 10.

The lifting operation is performed through the lifting mechanism 200 until the lifting mechanism 200 collides with the end of the piston rod 10 (when the piston rod 10 is disassembled, the disassembly of the installation part on the piston rod 10 cannot be performed because the end of the piston rod 10 needs to be collided due to the influence of the structure of the piston rod 10 itself), and then the disassembly operation is performed on the installation part 12 by using the wrench mechanism 300. Compared with the traditional dismounting mode (requiring the staff to manually apply force to conflict the end part of the piston connecting rod 10, but because of the space limitation in the locomotive, the staff can not apply force effectively), the auxiliary dismounting device realizes the alignment of the lifting mechanism 200 and the piston connecting rod 10 through the movement of the lifting mechanism 200 on the sliding mechanism 100, and applies force to the end part of the piston connecting rod 10 by utilizing the lifting mechanism 200, and finishes the dismounting of the mounting part 12 through the wrench mechanism 300, thereby greatly saving the manpower consumption, and facilitating the dismounting of the piston connecting rod 10.

In one embodiment, it is considered that the supporting mechanism 200 and the piston rod 10 need to generate a certain contact force when the auxiliary detaching device is used, because, in order to avoid the self structure of the supporting mechanism 200 from being damaged or deformed under the contact force, a 3D model of the auxiliary detaching device can be obtained through a computer, and a force application or pressure application test is performed on the supporting mechanism 200, so that the use effect of the auxiliary detaching device in the actual use process can be effectively ensured.

The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The communication interface of the computer is used for carrying out wired or wireless communication with an external terminal, and the wireless communication can be realized through WIFI, an operator network, NFC (near field communication) or other technologies. The computer program is executed by a processor to implement a feedback calculation of water flow rate or water flow velocity. The display screen of the computer can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer can be a touch layer covered on the display screen, a key, a track ball or a touch pad arranged on the shell of the computer, an external keyboard, a touch pad or a mouse and the like.
