Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] This utility model provides a torque tightening device for bogie vertical stop mounting bolts, solving the technical problem that the vertical stop bolts of current train bogies are inconvenient to tighten. This bogie vertical stop mounting bolt torque tightening device includes a ratchet head 1, a connecting rod 2, and a force-applying rod 3, wherein:

[0026] like Figure 1As shown, the ratchet head 1 is used to connect with a bolt. Specifically, the ratchet head 1 has a bolt hole in the middle that matches the bolt. The bolt is inserted into the bolt hole, and the ratchet head 1 rotates along the axial direction of the bolt, thereby driving the bolt to rotate, and thus tightening or loosening the bolt. The ratchet head 1 has components such as a ratchet and a pawl, so that when the handle is rotated in a certain direction, the pawl will engage in the tooth groove of the ratchet, pushing the ratchet and the bolt connected to it to rotate together; when the handle is rotated in the opposite direction, the pawl will slide out of the tooth groove of the ratchet under the action of the spring, so that the bolt and the ratchet head 1 are relatively stationary, thereby realizing unidirectional transmission, so as to apply force to the ratchet head 1 reciprocally, so that the rotation of the ratchet head 1 within a small range can drive the bolt to rotate.

[0027] like Figure 1 As shown, one end of the connecting rod 2 is mounted on one end of the ratchet head 1. Specifically, the connecting rod 2 is located at the end of the ratchet head 1 away from the bolt connection, and the extension direction of the connecting rod 2 is perpendicular to the extension direction of the ratchet head 1. This makes it more convenient to drive the ratchet head 1 to rotate in a narrow area by changing the force application position through the connecting rod 2.

[0028] like Figure 1 As shown, the force-applying rod 3 is installed on the end of the connecting rod 2 away from the ratchet head 1. The extension direction of the force-applying rod 3 is perpendicular to the extension direction of the connecting rod 2, that is, the force-applying rod 3 extends in the axial direction of the connecting rod 2. The extension direction of the force-applying rod 3 can be the same as or opposite to the extension direction of the fixing rod 4, or it can be in other directions. The specific extension direction of the force-applying rod 3 can be set according to the usage requirements. The extension of the force-applying rod 3 changes the force-applying position of the connecting rod 2, so that the force-applying direction of the force-applying rod 3 is the same as the force-applying direction of the ratchet head 1, thereby facilitating the tightening or loosening of the bolts of the vertical stop.

[0029] With the above structure, the bogie vertical stop mounting bolt torque tightening device provided by this utility model, when in use, first inserts the ratchet head 1 into the bolt that needs to be tightened or loosened, and then applies force to the force-applying rod 3. The force-applying rod 3 transmits the force to the ratchet head 1 through the connecting rod 2, causing the ratchet head 1 to rotate, thereby completing the tightening or loosening of the bolt. Therefore, when it is necessary to loosen or tighten the bolts at the bogie vertical stop, the connection between the connecting rod 2 and the force-applying rod 3 makes the force application point located in a more spacious and easily operable unstable position, facilitating the application of force to the force-applying rod 3 and making it easier to complete the tightening or loosening of the bolt.

[0030] An optional implementation of this embodiment is as follows: To facilitate fixing the ratchet head 1, the bogie vertical stop mounting bolt torque tightening device further includes a fixing rod 4, such as... Figure 1As shown, one end of the fixing rod 4 is mounted on the end of the connecting rod 2 away from the force-applying rod 3. The axis of the fixing rod 4 is perpendicular to the connecting rod 2. The ratchet head 1 is mounted on the end of the fixing rod 4 away from the connecting rod 2. The fixing rod 4 extends the position of the ratchet head 1 so as to turn the bolt at a greater distance. By fixing ratchet heads 1 of different sizes on the fixing rod 4, it can be used to accommodate bolts of different sizes.

[0031] An optional implementation method of this embodiment is as follows: Figure 1 As shown, a groove 41 is provided on the side wall of the fixing rod 4, and the ratchet head 1 is installed in the groove 41. By changing the length of the ratchet head 1 extending out of the fixing rod 4, it can be adapted to different usage environments for tightening or loosening bolts. Specifically, when the area around the bolt is narrow, the length of the ratchet head 1 extending out of the fixing rod 4 can be shortened. When it is necessary to extend the distance of the ratchet head 1 to apply force to the connecting rod 2, the length of the ratchet head 1 extending out of the fixing rod 4 can be extended. The ratchet head 1 can be interference-fitted into the groove 41 to make the ratchet head 1 fixed and stable. More preferably, the ratchet head 1 is slidably installed in the slide groove. By adjusting the position of the ratchet head 1 in the slide groove, the length of the ratchet head 1 extending out of the fixing rod 4 can be adjusted, thereby making it more convenient to adapt to different usage environments. The ratchet head 1 is fixed by a fixing device. The fixing device is a component that can fix the ratchet head 1 into the groove 41 after the position of the ratchet head 1 is adjusted appropriately. Optionally, such as Figure 2 As shown, a screw 8 is rotatably mounted on the connecting rod 2. One end of the screw 8 extends into the groove 41. The ratchet head 1 is screwed to the screw 8 and abuts against the inner wall of the groove 41. Thus, when the screw 8 rotates, the ratchet head 1 moves with the rotation of the screw 8, thereby adjusting the length of the ratchet head 1 extending out of the fixed rod 4.

[0032] An optional implementation method of this embodiment is as follows: Figure 1-3 As shown, in order to facilitate the application of the corresponding torque to the bolts, the bolt torque tightening device for the bogie vertical stop also includes a rectangular block 5. The rectangular block 5 has at least two relatively parallel surfaces to facilitate clamping by the torque wrench. By applying and controlling the bolt tightening torque through the torque wrench, the tightening force of the bolts is ensured to be consistent, reducing the over-tightening or loosening of bolts caused by human factors and improving the working accuracy.

[0033] An optional implementation of this embodiment is as follows: To facilitate the application of force by the force-applying rod 3, the bogie vertical stop mounting bolt torque tightening device further includes a retaining ring 6, such as... Figure 3As shown, the retaining ring 6 is installed at the end of the connecting rod 2 away from the ratchet head 1. The axis of the retaining ring 6 is perpendicular to the axis of the connecting rod 2. The force-applying rod 3 is slidably installed inside the retaining ring 6. The force-applying rod 3 slides along the axis of the retaining ring 6, thereby adjusting the position of the force-applying rod 3. When there are other objects blocking the use environment, the force-applying rod 3 is slid to move along the axis of the retaining ring 6, thereby avoiding the force applied by other objects, making it more convenient to use.

[0034] An optional implementation of this embodiment is as follows: To reduce the movement of the force-applying rod 3 outside the baffle 7, the bogie vertical stop mounting bolt torque tightening device further includes the baffle 7, such as... Figure 3 As shown, the baffle 7 is installed on the force-applying rod 3 and located at both ends of the force-applying rod 3. The baffle 7 is used to prevent the force-applying rod 3 from moving radially out of the fixed ring 6, reducing the need to pay attention to the position of the force-applying rod 3 during use and making it more convenient to use.

[0035] An optional implementation of this embodiment is as follows: the baffle 7 is detachably installed at both ends of the force-applying rod 3. By removing the baffle 7, it is easier to replace different force-applying rods 3, so as to facilitate replacement according to different usage environments. At the same time, the baffle 7 can also play a limiting role during use.

[0036] An optional implementation of this embodiment is as follows: The two ends of the force-applying rod 3 are threaded, and the force-applying rod 3 is screwed into the fixing ring 6. When force needs to be applied to the force-applying rod 3, the screwing of the force-applying rod 3 into the fixing ring 6 can fix the force-applying rod 3, thereby reducing the axial movement of the force-applying rod 3 along the fixing ring 6 when force is applied, making it safer to use. At the same time, the threads can also limit the movement of the fastening device, reducing the movement of the force-applying rod 3 outside the fixing ring 6. By rotating the force-applying rod 3, the force-applying rod 3 can be unscrewed outside the fixing ring 6, thereby facilitating the replacement of the force-applying rod 3 and making it convenient to use.

[0037] In summary, the bogie vertical stop mounting bolt torque tightening device provided by this utility model, when in use, first inserts the ratchet head 1 into the bolt that needs to be tightened or loosened, then applies force to the force-applying rod 3. The force-applying rod 3 transmits the force to the fixed rod 4 through the connecting rod 2, causing the ratchet head 1 to rotate, thereby completing the tightening or loosening of the bolt. By changing the length of the ratchet head 1 extending beyond the fixed rod 4, it can be adapted to tightening or loosening bolts in different operating environments. Therefore, when it is necessary to loosen or tighten the bolts at the bogie vertical stop, the connection between the connecting rod 2 and the force-applying rod 3 makes the force application point located in a more spacious and easily operable unstable area, facilitating the application of force to the force-applying rod 3 and making it easier to complete the loosening or tightening of the bolts.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
