Description

Technical Field

[0001] This invention relates to the field of turning gears, and particularly to a portable turning gear for internal combustion locomotives. Background Technology

[0002] In various locomotive diesel engine repair procedures, turning the engine around is an indispensable step. Turning the engine around involves rotating the load driven by the motor several times before starting it. This is done to check if the load (mechanical or transmission parts) is jammed, causing increased resistance, thus preventing excessive starting load and potential damage to the motor. Currently, 220V or 380V AC power is typically used to power the turning mechanism. This mechanism is complex, heavy, and requires a long power cable, making it time-consuming, labor-intensive, and inconvenient to carry. It also operates in environments with limited space. Furthermore, different locomotives have different input shafts, meaning existing turning mechanisms are not universally applicable and have a limited range of applications. Summary of the Invention

[0003] This invention provides a portable turning device for internal combustion locomotives, which can be adapted to different input shafts of different models of internal combustion engines. It can drive the input shaft to rotate through DC power supply. The overall structure of the turning device is compact and easy to carry.

[0004] This invention provides a portable internal combustion locomotive turning device, including a frame with a rotatable rotating shaft on the frame. One end of the rotating shaft is connected to a power mechanism for driving its rotation, and the other end is detachably connected to a magic cube disk. The magic cube disk can be connected to the input shaft of the internal combustion locomotive. The frame is also provided with a limiting component, which can form a limiting structure with the panel of the internal combustion locomotive used to fix the input shaft, so as to restrict the frame from rotating circumferentially.

[0005] In one embodiment, the frame includes a first support and a second support. The first support has a slot for accommodating the Rubik's Cube disk. One end of the rotating shaft passes through the second support, and the other end is connected to the Rubik's Cube disk. In this embodiment, the first support can position the Rubik's Cube disk, and when the rotating shaft is connected to the Rubik's Cube disk and drives the Rubik's Cube disk to rotate, the stability of the Rubik's Cube disk during rotation is ensured.

[0006] In one embodiment, a plurality of tie rods are provided between the first support and the second support, all of which are distributed circumferentially and whose axes are parallel to each other. This embodiment extends the distance between the end faces of the first and second supports by providing tie rods, thereby increasing the length of the rotation axis and enhancing the overall structural strength.

[0007] In one embodiment, one end of the pull rod is connected to the first support, and the other end is detachably connected to the second support via a nut assembly. This embodiment achieves a detachable connection between the first and second supports, facilitating transport, disassembly, and maintenance.

[0008] In one embodiment, the power mechanism includes an electric torque wrench, the end of the rotating shaft has a connecting groove adapted to the output shaft of the electric torque wrench, the second support has a keyway located axially outside the connecting groove, and the housing of the electric torque wrench has a protrusion adapted to the keyway. Through this embodiment, a quick connection to the rotating shaft is achieved via the electric torque wrench, and the keyway and protrusion ensure that when the electric torque wrench drives the rotating shaft to rotate, the housing and frame of the electric torque wrench function as a single unit.

[0009] In one embodiment, the Rubik's Cube is a magnetic component and can be magnetically connected to the inner wall of the slot. This embodiment facilitates quick replacement and installation of the Rubik's Cube.

[0010] In one embodiment, the limiting assembly includes a fixing head, a fixing rod, a slider, and a limiting nut. One end of the fixing rod is connected to the fixing head, and the other end is threaded to the limiting nut. The slider is sleeved on the fixing rod and can move along its axial direction. A clamping space for holding the frame and the panel is formed between the fixing head and the slider. In this embodiment, the limiting assembly connects the frame to the panel of the diesel locomotive, providing fixed support for the frame. Simultaneously, when the input shaft of the rotating shaft is rotated, the limiting assembly also provides a reaction force.

[0011] In one embodiment, the limiting component includes a limiting groove formed on the frame, which can accommodate bolts on the panel and form a circumferential limiting structure therewith. In this embodiment, during the rotation of the input shaft driven by the rotating shaft, the limiting groove can engage with the bolts on the panel, and the rotating shaft provides a reaction force to the frame, reducing manual labor intensity.

[0012] In one embodiment, the number of the limiting grooves is multiple, and all the limiting grooves are evenly distributed in a ring-shaped interval.

[0013] In one embodiment, a pivot support is further provided on the frame, the pivot support is sleeved on the rotating shaft, and the pivot support has a through hole that is adapted to the rotating shaft. This embodiment improves the stability of the rotating shaft during rotation.

[0014] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of the present invention can be achieved.

[0015] The portable turning gear device for internal combustion locomotives provided by the present invention, compared with the prior art, has at least the following features:

[0016] Beneficial effects:

[0017] This application achieves a quick and flexible transmission connection with the input shaft of an internal combustion locomotive through a frame, a rotating shaft, and a magic cube. The structure is simple and compact, easy to carry, and the replaceable magic cube can be adapted to various input shafts of different specifications, thus improving the applicability.

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the present invention provides a portable internal combustion locomotive turning device, including a frame 10, on which a rotatable rotating shaft 20 is provided. One end of the rotating shaft 20 is connected to a power mechanism for driving its rotation, and the other end is detachably connected to a magic cube disk 30. The magic cube disk 30 can be connected to the input shaft of the internal combustion locomotive. A limiting component is also provided on the frame 10. The limiting component can form a limiting structure with the panel of the internal combustion locomotive used to fix the input shaft, so as to limit the circumferential rotation of the frame 10.

[0025] Specifically, during use, the turning device of this application maintains a relatively stationary position by forming a limiting structure between the frame 10 and the panel of the internal combustion locomotive. The rotation of the rotating shaft 20 drives the input shaft to rotate, achieving the turning effect. The rotating shaft 20 is located inside the frame 10 and can rotate relative to the frame 10 around its own axis. One end of the rotating shaft 20 passes through the frame 10 and can be connected to the power mechanism, while the other end is connected to the magic cube 30, which has a connection structure that can be adapted to the input shaft. Through the rotating shaft 20 and the frame 10, flexible torque transmission is achieved, with soft start and soft stop, and good braking characteristics, eliminating the need for mechanical or electromagnetic braking devices.

[0026] Further explanation is needed, taking one type of crankshaft turning mechanism as an example: During the final assembly, component assembly, inspection, adjustment, routine maintenance, and repair of the diesel engine, it is frequently necessary to turn the crankshaft. Therefore, a crankshaft turning mechanism is installed on the diesel engine. This mechanism is mounted on the end plate at the engine block's output end, located inside the connecting box, to the right of the flexible coupling. It consists of a support, sliding bracket, sliding shaft, sliding bearing, bevel gear, worm gear, limit switch, and pointer. The worm gear is made of cast bronze and is fitted onto the worm shaft, with the two connected by two locating pins. The worm shaft is hollow, with an oil cup at its lower end for injecting grease to lubricate the bearings at both ends. The worm shaft is mounted on the sliding bracket, which is mounted on a pad. The pad is secured to the engine block's output end plate to the right of the flexible coupling inside the connecting box. During the turning operation, use both hands to pull up the handle sleeve of the positioning pin and push the sliding bracket towards the flexible coupling, so that the worm gear on the turning mechanism meshes with the gear disc on the flexible coupling (when installing the turning mechanism, ensure that the gap between them is 0.1~0.55mm, and the gap between the bevel gear on the turning mechanism and the gear disc of the flexible coupling is not less than 0.5mm to avoid interference during turning. After adjusting these two gaps, use two tapered pins for positioning, and then use bolts to tighten the base plate to the machine body). At this time, the cam will release the contacts of the limit switch, and the limit switch will cut off the diesel engine starting circuit, thus preventing the diesel engine from starting and running during turning to avoid accidents. At this time, engage the magic cube 30 onto the hexagon of the gear shaft of the turning mechanism. Connect the power mechanism and the rotating shaft 20, open the safety lock, select the direction to be turned, and press the start / stop trigger of the power mechanism to start turning.

[0027] After the rotation is completed, first disconnect the power mechanism from the rotating shaft 20. Then, use both hands to pull up the handle sleeve on the locating pin and pull the sliding bracket outward to reset it, so that the worm gear disengages from the gear disc of the flexible coupling. It can be adjusted by the adjusting shims and adjusting rings between the bearing body and the sliding bracket. After adjustment, drill and ream the tapered pin hole together with the shim plate, and install the locating pin. At this point, the rotation is complete.

[0028] In one embodiment, the frame 10 includes a first support 11 and a second support 12. The first support 11 has a slot for accommodating the Rubik's Cube disk 30. One end of the rotating shaft 20 passes through the second support 12, and the other end is connected to the Rubik's Cube disk 30. In this embodiment, the first support 11 can position the Rubik's Cube disk 30, and when the rotating shaft 20 is connected to the Rubik's Cube disk 30 and drives the Rubik's Cube disk 30 to rotate, the stability of the Rubik's Cube disk 30 during rotation is ensured.

[0029] Specifically, the first support 11 and the second support 12 are separate structures, with one end of the rotating shaft 20 protruding from the second support 12. A connection for a power mechanism is provided at the end of the rotating shaft 20. A slot is provided on the first support 11, and the cube disk 30 is placed within the slot and can rotate along the inside of the slot. The slot on the first support 11 provides support and positioning for the cube disk 30. Preferably, the cube disk 30 and the rotating shaft 20 are connected by a flange and a groove, ensuring synchronous rotation without affecting axial displacement, thus allowing for the replacement of cube disks 30 of different specifications. Similarly, multiple groove structures can be provided in the middle of the cube disk 30, allowing the same cube disk 30 to be connected to various input shafts of different specifications.

[0030] In one embodiment, a plurality of tie rods 13 are provided between the first support 11 and the second support 12. All tie rods 13 are distributed circumferentially, and the axes of all tie rods 13 are parallel to each other. By providing tie rods 13, the end face distance between the first support 11 and the second support 12 is extended, the length of the rotation shaft 20 is increased, and the overall structural strength is enhanced.

[0031] Specifically, compared to the first support 11 and the second support 12 being a solid, integral structure, the first support 11 and the second support 12 are connected by tie rods 13. This reduces the overall weight for easier transport while increasing structural strength and facilitating maintenance. Using multiple tie rods 13 to distribute the load makes the structure more compact and achieves optimal load balance. This stable performance significantly reduces vibration.

[0032] In one embodiment, one end of the pull rod 13 is connected to the first support 11, and the other end is detachably connected to the second support 12 via a nut assembly 131. This embodiment achieves a detachable connection between the first support 11 and the second support 12, facilitating carrying, disassembly, and maintenance.

[0033] Specifically, the tie rod 13 and the first support 11 can be connected by threads, welding, or countersunk holes to form a limiting structure.

[0034] In one embodiment, the power mechanism includes an electric torque wrench. The end of the rotating shaft 20 has a connecting groove that matches the output shaft of the electric torque wrench. The second support 12 has a keyway 21 located axially outside the connecting groove. The housing of the electric torque wrench has a protrusion that matches the keyway 21. In this embodiment, the electric torque wrench enables quick connection to the rotating shaft 20. The keyway 21 and the protrusion ensure that when the electric torque wrench drives the rotating shaft 20 to rotate, the housing of the electric torque wrench and the frame 10 function as a single unit.

[0035] Specifically, during use, the output shaft of the electric torque wrench is connected to the rotating shaft 20. The housing of the electric torque wrench is connected to the frame 10 through the protrusion and keyway 21. That is, the housing of the electric torque wrench and the frame 10 form a circumferential limiting structure, which eliminates the need for manual application of external force to fix the housing of the electric torque wrench in order to provide the reaction force for the rotation of the output shaft, thus reducing the intensity of manual labor.

[0036] In one embodiment, the Rubik's Cube 30 is a magnetic component and can be magnetically connected to the inner wall of the slot. This embodiment facilitates quick replacement and installation of the Rubik's Cube 30.

[0037] Specifically, magnetic materials can be used to partially attach the inner walls of the cube disk 30 and / or the slots, or magnet blocks can be installed by embedding.

[0038] In one embodiment, the limiting assembly includes a fixing clamp 40, a fixing rod 41, a slider 42, and a limiting nut 43. One end of the fixing rod 41 is connected to the fixing clamp 40, and the other end is threadedly connected to the limiting nut 43. The slider 42 is sleeved on the fixing rod 41 and can move along its axial direction. A clamping space for holding the frame 10 and the panel is formed between the fixing clamp 40 and the slider 42. In this embodiment, the limiting assembly connects the frame 10 and the panel of the diesel locomotive, providing fixed support for the frame 10. Simultaneously, when the input shaft of the rotating shaft 20 is driven to rotate, the limiting assembly can also provide a reaction force.

[0039] Specifically, the limiting nut 43 limits the slider 42, ensuring that the first support 11 fits against the panel as a whole during clamping. The fixing head 40 and slider 42 are positioned on opposite sides of this whole. Adjusting the limiting nut 43 allows the fixing head 40 and slider 42 to engage and clamp the entire assembly. This ensures that the frame 10 remains integrated with the diesel locomotive's panel during operation. During the rotation of the rotating shaft 20 and input shaft, the limiting assembly provides a reaction force to the frame 10.

[0040] In one embodiment, the limiting component includes a limiting groove 50 formed on the frame 10, which can accommodate bolts on the panel and form a circumferential limiting structure therewith. In this embodiment, during the rotation of the input shaft driven by the rotating shaft 20, the limiting groove 50 can engage with the bolts on the panel, and the rotating shaft 20 provides a reaction force to the frame 10 when it rotates, reducing the intensity of manual labor.

[0041] In one embodiment, there are multiple limiting grooves 50, and all the limiting grooves 50 are evenly distributed in a ring-shaped interval.

[0042] In one embodiment, a pivot support 60 is also provided on the frame 10. The pivot support 60 is sleeved on the rotating shaft 20, and the pivot support 60 has a through hole that is compatible with the rotating shaft 20. This embodiment improves the stability of the rotating shaft 20 during rotation.
