[0040] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1 and Figure 2 As shown, a typical embodiment of the present invention provides a Dongfeng B-type locomotive cylinder throwing tool, including a set 1, the set 1 includes a first set plate 1-1 and a second set plate 1-2 that can be opened and closed with each other, a fastening groove that can be sleeved in the groove of the rack is formed between the first set plate 1-1 and the second set plate 1-2, when the rack is at the oil stop position, it is sleeved in the groove of the rack through the fastening groove, and the set 1 is blocked by the chuck pin, so that the rack can be kept at the oil stop position.

[0042] When using the first embodiment, firstly, the collet pin is pulled out from the groove of the rack, and the collet pin is stabilized in a state of being out of the groove of the rack;

[0043] Pull out the rack to the oil stop position, and put the set 1 inside the groove of the rack. At this time, the fastening groove is located in the groove of the rack, and the chuck pin blocks the set 1, so that the rack is blocked at the oil stop position, which is convenient for the cylinder swinging operation.

[0044] A cylinder-swinging tool for Dongfeng 8B locomotive, further comprising:

[0045] The connecting bolt 2 and the dovetail nut 3 are arranged between one of the same side ends of the first set of plates 1-1 and the second set of plates 1-2, and are used to fasten the first set of plates 1-1 and the second set of plates 1-2, and are inserted between the other same side ends of the first set of plates 1-1 and the second set of plates 1-2;

[0046] The fastening bolt 4 is installed on the first set plate 1-1. One end of the fastening bolt 4 passes through the first set plate 1-1 and abuts against the inner wall of the groove of the rack, so as to lock the set 1 on the rack.

[0047] When the rack is pulled out to the oil stop position, first open the first set plate 1-1 and the second set plate 1-2, then sleeve the fastening groove into the groove of the rack, connect the dovetail nut 3 with the connecting bolt 2, and rotate the dovetail nut 3 so that the dovetail nut 3 closes the ends of the first set plate 1-1 and the second set plate 1-2, so that the set 1 can be sleeved into the groove of the rack;

[0048] After the ends of the first set of plates 1-1 and the second set of plates 1-2 are closed, the fastening bolt 4 is inserted into the first set of plates 1-1 and rotated so that the end of the fastening bolt 4 abuts against the inner wall surface of the groove of the rack, so that the set 1 is locked on the rack. At this time, the position of the fastening bolt 4 corresponds to the position of the chuck pin. At this time, if the rack is reset, the chuck pin blocks the fastening bolt 4, thereby preventing the rack from resetting and keeping the rack at the oil stop position.

[0049] like Figures 3 to 6 As shown, a Dongfeng 8B locomotive cylinder throwing tool also includes:

[0050] The winding rod 5 is rotatably mounted on the first set of plates 1-1 and is arranged perpendicular to the rack. It is used to wind a wire with one end fixed to the peripheral parts of the internal combustion engine, and fix the rack at the oil stop position through a pulling force.

[0051] When using the second embodiment, firstly wind the wire around the internal combustion engine parts around the rack, then repeat the steps of installing the tool 1 in the groove of the rack, and then rotate the winding rod 5 so that the wire is wound into a taut state to keep the rack at the oil stop position.

[0052] A cylinder-swinging tool for Dongfeng 8B locomotive, further comprising:

[0053] The plug-in tube 6 is fixedly mounted on the outer surface of the first set of plates 1-1, and the winding rod 5 includes a plug-in portion 5-1 whose bottom end can be inserted into the plug-in tube 6;

[0054] The clamping groove 5-2 is in a "U" shape and is arranged at the bottom end of the plug-in portion 5-1 for clamping the iron wire.

[0055] Before winding the wire, place the end of the wire at the end of the plug-in tube 6, align the slot 5-2 with the wire, and allow the wire to enter the slot 5-2;

[0056] The winding rod 5 is then pressed downward. At this time, the winding rod 5 drives the iron wire to be inserted into the plug-in tube 6, so that the iron wire is squeezed by the slot 5-2 and the plug-in tube 6, and the iron wire is shaped into a "U" shape, so that when the winding rod 5 rotates, the unwound iron wire can be wound around the outside of the iron wire that has been shaped into a "U" shape, thereby preventing the iron wire from falling off the winding rod 5 when the iron wire is subsequently wound.

[0057] A cylinder-swinging tool for Dongfeng 8B locomotive, further comprising:

[0058] The winding rod 5 also includes a rod-shaped portion 5-3 fixedly mounted on the top of the plug-in portion 5-1, and the surface of the rod-shaped portion 5-3 is provided with inclined grooves 5-4 distributed equidistantly along the circumferential direction, and a side wall of the inclined groove 5-4 facing the center of the rod-shaped portion 5-3 is in a state where the bottom end is inclined inwards;

[0059] A cylinder-swinging tool for Dongfeng 8B locomotive, comprising:

[0060] The rotating ring 7 is slidably mounted on the rod-shaped portion 5-3;

[0061] The moving rod 8 is arranged in an inverted "L" shape structure, and a plurality of moving rods 8 are arranged equidistantly in the circumferential direction of the rotating ring 7, and the moving rod 8 is arranged to be able to move radially along the rotating ring 7. The end of the transverse part of the moving rod 8 is slidably matched with the inclined groove 5-4. When the winding rod 5 moves downward in the rotating ring 7, the inclined groove 5-4 drives the moving rod 8 to move outward.

[0062] When the winding rod 5 is rotated, since one end of the iron wire wound around the internal combustion engine component is higher than the rack, the iron wire will move upward along the winding rod 5 when winding;

[0063] When the iron wire is wound into the range of the moving rod 8, the winding rod 5 continues to rotate. Since the moving rod 8 is slidably installed in the inclined groove 5-4, the winding rod 5 drives the moving rod 8 to rotate synchronously. At this time, the moving rod 8 is pulled by the iron wire, which squeezes the moving rod 8 and moves.

[0064] At this time, the inclined groove 5-4 is squeezed by the moving rod 8, causing the winding rod 5 to move upward, reducing the spacing of the iron wire wound at the bottom, making the iron wire winding tighter, increasing the shaping effect of the iron wire, making the pulling force of the iron wire greater, and preventing the rack from shaking when the cylinder is swung.

[0065] A cylinder-swinging tool for Dongfeng 8B locomotive, further comprising:

[0066] The cone sleeve 9 is movably mounted on the plug-in portion 5-1 and is arranged with its tip facing downward, and the outer diameter of the top of the cone sleeve 9 matches the outer diameter of the circle where the moving rod 8 is located when it is at the bottom of the inclined groove 5-4;

[0067] The fixed rod 9-1 is fixedly arranged on the lower surface of the rotating ring 7, and the cone sleeve 9 is fixedly connected to the bottom end of the fixed rod 9-1, so that the moving rod 8 is located between the cone sleeve 9 and the rotating ring 7, and the fixed rod 9-1 is always located on the inner side of the moving rod 8 in the radial direction of the rod-shaped portion 5-3.

[0068] When the iron wire is wound upward, it first passes through the cone sleeve 9, which has a guiding effect on the iron wire, so that the iron wire to be wound can enter the range of the moving rod 8 more easily;

[0069] When the iron wire enters the longitudinal part of the first moving rod, the winding rod 5 continues to rotate, which can drive the moving rod 8 to move and drive the winding rod 5 to rise;

[0070] Specifically, the fixing rod 9 - 1 is in contact with the winding rod 5 , so that the winding rod 5 can remain stable when rising.

[0071] A cylinder-swinging tool for Dongfeng 8B locomotive, further comprising:

[0072] A mounting frame 10 is fixedly mounted on the first set of plates 1 - 1 , and a rotating ring 7 is rotatably mounted on the mounting frame 10;

[0073] The baffle 10-1 is rotatably mounted on the mounting frame 10;

[0074] The first set of plates 1-1 and the second set of plates 1-2 are arranged up and down;

[0075] When the set 1 is placed in the groove of the rack, the baffle 10-1 is fixed, and one end of the baffle 10-1 is located above the winding rod 5, so as to limit the highest position of the winding rod 5;

[0076] After the set 1 is opened, the end of the baffle 10 - 1 located above the winding rod 5 can be rotated upward out of the area where the winding rod 5 is located.

[0077] When the winding rod 5 moves to the highest position, the top end of the winding rod 5 contacts the bottom surface of the baffle 10-1 and is blocked by the baffle 10-1, so that the winding rod 5 can be kept at a specified height to tighten the wire rope;

[0078] When the winding rod 5 is rotated, the rotating ring 7 will rotate on the mounting frame 10, making it easier for the moving rod 8 to wind the iron wire. At the same time, the rotating ring 7 will limit the winding height of the iron wire, so that the spacing between the iron wires becomes smaller when the winding rod 5 rises subsequently, thereby increasing the shaping effect and preventing the iron wire from falling off.

[0079] A cylinder-swinging tool for Dongfeng 8B locomotive, further comprising:

[0080] The top rod 11 is fixedly mounted on the second set of plates 1 - 2 . When the set 1 is in a closed state, the top end of the top rod 11 can support one end of the baffle 10 - 1 away from the winding rod 5 , so that the other end of the baffle 10 - 1 is located above the winding rod 5 .

[0081] When the second set of plates 1-2 is closed with the first set of plates 1-1, the top rod 11 presses against the bottom surface of the baffle 10-1 away from the winding rod 5, so that the baffle 10-1 is restricted by the top rod 11 and the highest position to which the winding rod 5 can rise is limited. At this time, a stable support can be formed between the top rod 11, the winding rod 5 and the baffle 10-1;

[0082] When the device needs to be disassembled, the ends of the second set of plates 1-2 and the first set of plates 1-1 are opened to keep the top rod 11 away from the baffle 10-1, so that the winding rod 5 can be pulled out from the rotating ring 7, and the device can be disassembled as a whole;

[0083] At this time, the iron wire is shaped and can maintain the winding state. Next time when the cylinder is thrown, it is only necessary to reinsert the winding rod 5 into the rotating ring 7 and connect the "U"-shaped part of the iron wire with the card slot 5-2.

[0084] Then close the first set of plates 1-1 and the second set of plates 1-2 to perform the cylinder swinging operation. If the wire is not in a taut state at this time, press the winding rod 5 downward so that the moving rod 8 drives the wire to expand outward, so that the wire is in a taut state here.

[0085] A cylinder-swinging tool for Dongfeng 8B locomotive, further comprising:

[0086] The matching anti-slip bolt 12 and anti-slip thread groove 5-5, the anti-slip bolt 12 is rotatably installed on the baffle 10-1 to block the end of the winding rod 5, the anti-slip thread groove 5-5 is set at the top of the rod-shaped part 5-3, and the rotation direction of the anti-slip bolt 12 when it is rotated out of the anti-slip thread groove 5-5 is opposite to the rotation direction when the winding rod 5 releases the wire.

[0087] When the iron wire is in a taut state, the end of the winding rod 5 contacts the bottom surface of the baffle 10-1, and the anti-slip thread groove 5-5 corresponds to the anti-slip bolt 12. Then the anti-slip bolt 12 is rotated to connect the anti-slip bolt 12 to the winding rod 5, so that the winding rod 5 is completely locked in the state of taut the iron wire.

[0088] Compared with the first embodiment, the second embodiment has the function of keeping the rack at the oil stop position, avoiding errors during processing, resulting in the chuck pin being unable to completely block the sleeve 1, resulting in the rack still having a limiting effect when the cylinder is thrown.

[0089] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
