Description

Technical Field

[0001] The invention relates to the field of rail vehicle equipment, and in particular to a double-side acting coupler unhooking device and method. Background Art

[0002] The coupler is a device that enables the connection between a locomotive and a vehicle (or locomotive). The coupler lifting rod unlocks the connected coupler, and the uncoupling operation is achieved by operating the coupler lifting rod. The conventional uncoupling operation is achieved by using the lifting rod arranged on one side of the coupler. It is often necessary to cross the rails to reach one side of the distribution lifting rod for operation. However, when the mounted vehicle or locomotive is long, the detour distance is long, and the work efficiency and safety are low.

[0003] A Chinese patent (publication number CN203580985U, publication date 20140507) discloses a railway freight car coupler lifting rod, which is provided with coupler lifting rod seats located on both sides of the coupler and fixed on the car body at intervals, and the two coupler lifting rod seats are respectively provided with coupler lifting rods I and II, and also include support blocks fixed on both sides above the coupler, and coupler lifting rods III are movably provided in the support blocks, and coupler lifting rods III are connected to the coupler through a lifting rod chain ring, and one end of coupler lifting rods I and coupler lifting rods II are respectively connected to coupler lifting rods III to form a coupler lifting rod, but it does not have the function of preventing misoperation, there are safety risks, and the structure is relatively complex. Because the coupler lifting rod III in the middle position of the railway freight car coupler lifting rod needs to have a support block fixed on the car body as a rotation support. However, in the structure of the subway engineering vehicle, due to the presence of the impact seat and the driver's cab on the coupler, there is no space for fixing the support block, and the coupler lifting rod III cannot be arranged at the front end of the subway engineering vehicle, resulting in the combined coupler lifting rod structure adopted by it being not applicable; and the coupler lifting rod III in the middle position of the coupler lifting rod for railway freight cars is overlapped with the coupler lifting rod II on both sides. During the driving of the vehicle, the vibration generated by the operation will cause the coupler lifting rod to shake, and there is a risk of triggering the coupler to be unhooked, which makes it difficult to meet the use requirements of the subway engineering vehicle. Summary of the invention

[0004] The purpose of the present invention is to address the defects of the prior art and provide a double-sided coupling unhooking device and method. By rotatably setting operating lifting rods on both sides of the coupling, one end of the operating lifting rod cooperates with the driven ring of the middle lifting rod through a driving ring, and the two ends of the middle lifting rod form a supporting structure through the driven ring. The rotation of the single-sided operating lifting rod can be used to drive the middle lifting rod to rotate around the axis, so that the rotation of the middle lifting rod can be used to pull the connected hook to achieve unlocking. There is no need to set a supporting structure for the lifting rod above the coupling, which meets the coupling unlocking requirements of subway engineering vehicles and reduces safety risks.

[0005] The first object of the present invention is to provide a double-side acting coupler unhooking device, which adopts the following scheme:

[0006] include:

[0007] An operating lever is distributed on both sides of the coupler. A driving ring is provided at one end of the operating lever close to the coupler. The operating lever can rotate when driven by an external force.

[0008] The middle lifting rod has driven rings at both ends, and the two driven rings are correspondingly buckled with the driving rings on both sides of the hook, so that the middle lifting rod is erected outside the hook in a simply supported structure; the middle lifting rod can rotate with the operating lifting rod under the drive of at least one driving ring;

[0009] The hook lock iron is installed on the coupler and connected to the middle lifting rod. The hook lock iron unhooks and locks the coupler with the help of the rotation of the middle lifting rod.

[0010] Furthermore, the operating lifting rod is provided with an operating section and a transmission section, the transmission section is connected to the driving ring, and the transmission section rotates along with the rotation generated by the external force exerted on the operating section, so that the driving ring rotates around the axis of the transmission section, and the rotation of the driving ring is transmitted to the middle lifting rod by means of the driven ring.

[0011] Furthermore, the transmission section is rotatably matched with a lifting rod support, and the transmission sections of the operating lifting rods on both sides of the coupler are collinearly distributed.

[0012] Furthermore, the operating lever is equipped with an anti-misoperation mechanism, which includes a baffle plate. The anti-misoperation mechanism utilizes the movement of the baffle plate to unlock and lock the rotation of the operating lever.

[0013] Furthermore, the anti-misoperation mechanism also includes a vertical plate and a positioning pin. A limit area for accommodating the operating lever is formed between two vertical plates that are spaced apart. The positioning pin is installed on the vertical plate. A sliding groove that slides to match the positioning pin is provided on the baffle. The baffle uses the relative movement of the sliding groove and the positioning pin to block or open the limit area.

[0014] Furthermore, one radial side of the driven ring is connected to the main body of the intermediate lifting rod, and the driving ring can slide along the driven ring in the circumferential direction until it abuts against the main body of the intermediate lifting rod and then drives the intermediate lifting rod to rotate.

[0015] Furthermore, when the driving ring slides relative to the driven ring, the driving ring maintains support for the driven ring and the intermediate lifting rod.

[0016] Furthermore, the hook lock iron is connected to the middle lifting rod at intervals with a line connecting the two ends of the middle lifting rod, so that the hook lock iron is connected to the middle lifting rod and rotates around the rotation axis of the operating lifting rod.

[0017] The second object of the present invention is to provide a working method of the double-side acting coupler unhooking device as described in the first object, comprising:

[0018] When unlocking the coupler, the operating lever is controlled from the locomotive side to rotate the operating lever to rotate the driving ring;

[0019] After the driving ring idles to set the stroke, it forms a stable contact with the middle lifting rod, thereby driving the middle lifting rod to rotate, so that the hook lock iron unlocks the coupler;

[0020] When locking the coupler, release the operating lever and reset it, and the coupler lock iron will resume the locked state of the coupler.

[0021] Furthermore, when the hook lock iron is unhooked by the operating lifting rod on either side of the coupler, the operating lifting rod on the other side maintains support for the middle lifting rod.

[0022] Compared with the prior art, the present invention has the following advantages and positive effects:

[0023] In view of the problem that there is no support structure for the coupler lifting rod above the front end of the coupler in the driver's cab of the current subway engineering vehicle, by rotatably setting operating lifting rods on both sides of the coupler, one end of the operating lifting rod cooperates with the driven ring of the middle lifting rod through a driving ring, and the two ends of the middle lifting rod form a support structure through the driven ring, and the rotation of the single-sided operating lifting rod can be used to drive the middle lifting rod to rotate around the axis, so that the rotation of the middle lifting rod can be used to pull the connected coupler to achieve unlocking, and there is no need to set a support structure for the lifting rod above the coupler, which meets the coupler unlocking needs of the subway engineering vehicle and reduces safety risks.

[0024] Through the coordination of the vertical plate, the positioning pin and the slide slot, the movement of the baffle is more accurate and controllable, further improving the reliability and stability of the anti-misoperation mechanism. In view of the defect of the original structure without the anti-misoperation function, a complete and reliable anti-misoperation solution is provided to improve the safety of the device in actual use.

[0025] The connection between the hook lock iron and the middle lifting rod and the connection line between the two ends of the middle lifting rod are spaced apart, so that the connection between the hook lock iron and the middle lifting rod rotates around the rotation axis of the operating lifting rod, increasing the movement stroke of the middle lifting rod driving the hook lock iron and meeting the needs of the hook lock iron to control the coupler. When the middle lifting rod rotates, the hook lock iron can perform the unhooking and locking actions of the coupler more smoothly, optimize the movement trajectory of the hook lock iron, and improve the accuracy of the unhooking and locking operations of the coupler.

[0034] Example 1

[0035] In a typical embodiment of the present invention, Figure 1-Figure 6 As shown, a double-side acting coupler unhooking device is provided.

[0036] The existing railway freight car hook 9 lifting rod has no anti-misoperation function and a complex structure. In subway engineering vehicles, due to space limitations and the risk of triggering the hook 9 unhooking due to running shaking, it is difficult to meet the use needs of subway engineering vehicles. Based on this, this embodiment provides a double-sided hook 9 unhooking device, which uses the operating lifting rods 3 on both sides to set up the middle lifting rod 5. The middle lifting rod 5 can be driven by the operating lifting rod 3 at the same time or separately to move, thereby realizing the unhooking or locking of the hook 9, solving the space limitation problem that the original railway freight car hook 9 lifting rod cannot be arranged at the front end of the subway engineering vehicle due to the impact seat and the driver's cab on the hook 9 in the subway engineering vehicle structure.

[0037] like Figure 1As shown, the double-side acting coupler 9 unhooking device mainly includes an operating lifting rod 3, an intermediate lifting rod 5 and a hook lock iron 10. The operating lifting rod 3 is distributed on both sides of the coupler 9. A driving ring 11 is provided near one end of the coupler 9 and can rotate when driven by an external force. It can accept the external force and provide power input, and drive the intermediate lifting rod 5 by rotating, thereby realizing the unlocking or locking operation of the coupler 9. A driven ring 12 is provided at both ends of the intermediate lifting rod 5. The two driven rings 12 correspond to the driving rings 11 of the operating lifting rod 3 on both sides of the coupler 9, and are erected outside the coupler 9 in a simply supported structure, and can rotate with the operating lifting rod 3 driven by at least one driving ring 11. The intermediate lifting rod 5 forms a stable supporting structure, and there is no need to set an additional supporting structure above the coupler 9, which solves the problem of space limitation of the subway engineering vehicle. At the same time, the coupling 9 is unlocked or locked by cooperating with the operating lifting rod 3 to transmit power.

[0038] The hook lock iron 10 is installed on the coupler 9 and connected to the intermediate lifting rod 5. The coupler 9 is unhooked and locked by means of the rotation of the intermediate lifting rod 5. The component that directly performs the unhooking and locking actions of the coupler 9 converts the rotation of the intermediate lifting rod 5 into the unlocking or locking operation of the coupler 9.

[0039] The invention meets the unlocking requirements of the coupler 9 of the subway engineering vehicle, and overcomes the problem that the lifting rod of the coupler 9 of the original railway freight car cannot be arranged due to the structural characteristics of the subway engineering vehicle. There is no need to set a supporting structure of the lifting rod above the coupler 9, which simplifies the structure and solves the problem of the original complex structure.

[0040] like Figure 1 As shown, the operating lever 3 is provided with an operating section and a transmission section, the transmission section is connected to the drive ring 11, and the transmission section rotates with the rotation of the operating section caused by the external force, so that the drive ring 11 rotates around the axis of the transmission section, as shown in FIG. Figure 3 As shown, the rotation of the driving ring 11 is transmitted to the middle lifting rod 5 by means of the driven ring 12, which can effectively transmit the operating external force to the middle lifting rod 5, realize the reasonable transmission and conversion of the operating force, and enable the operating lifting rod 3 to drive the middle lifting rod 5 to rotate more accurately.

[0041] Aiming at the problem of the complicated structure of the lifting rod of the original railway freight car coupler 9, the internal structure of the operating lifting rod 3 is optimized, the force transmission path is simplified, and the rationality and simplicity of the overall structure are improved.

[0042] like Figure 1 As shown, the transmission section is rotated with the lifting rod support 2, and the transmission sections of the operating lifting rods 3 on both sides of the coupler 9 are collinearly distributed. The lifting rod support 2 provides rotation support for the transmission section of the operating lifting rod 3 to ensure the stability of the transmission section rotation, and the collinear distribution of the transmission sections on both sides further optimizes the structural layout, making the transmission of the operating force smoother.

[0043] Among them, the transmission section can be matched with multiple lifting rod supports 2 to improve stability. In this embodiment, the transmission section of each operating lifting rod 3 is matched with two lifting rod supports 2, namely the first lifting rod support 2 and the second lifting rod support 4. Compared with the original railway freight car lifting rod with a hook 9, this design improves the structural stability while meeting the use requirements of subway engineering vehicles by reasonably arranging the lifting rod supports 2 and the colinear distribution of the transmission section, and solves the instability problem of the original structure that may be caused by unreasonable layout.

[0044] like Figure 4 , Figure 5 and Figure 6 As shown, the operating lever 3 is equipped with an anti-misoperation mechanism 1, which includes a baffle 7, and the movement of the baffle 7 is used to unlock and lock the rotation of the operating lever 3. This mechanism is unlocked when operation is required and locked when misoperation is prevented by setting the baffle 7, which effectively avoids the operating lever 3 from being triggered by mistake and enhances the safety of the device. It directly solves the problem that the lifting lever of the original railway freight car coupler 9 does not have the anti-misoperation function and there is a safety risk, and greatly improves the safety of the double-side acting coupler 9 unhooking device.

[0045] Specifically, Figure 5 and Figure 6 As shown, the anti-misoperation mechanism 1 also includes a vertical plate 6 and a positioning pin 8. A limit zone for accommodating the operating lever 3 is formed between two vertical plates 6 that are spaced apart. The positioning pin 8 is installed on the vertical plate 6. The baffle plate 7 is provided with a slide groove that slides to match the positioning pin 8. The baffle plate 7 uses the relative movement of the slide groove and the positioning pin 8 to block or open the limit zone. Through the cooperation of the vertical plate 6, the positioning pin 8 and the slide groove, the movement of the baffle plate 7 is more precise and controllable, further improving the reliability and stability of the anti-misoperation mechanism 1. In view of the defect that the original structure has no anti-misoperation function, a complete and reliable anti-misoperation solution is provided to improve the safety of the device in actual use.

[0046] like Figure 2 and Figure 3 As shown, the driven ring 12 is connected to the main part of the middle lifting rod 5 on one radial side, and the driving ring 11 can slide along the driven ring 12 in the circumferential direction until it abuts against the main part of the middle lifting rod 5 and then drive the middle lifting rod 5 to rotate, making the connection between the driving ring 11 and the driven ring 12 more flexible, while ensuring power transmission, providing a reasonable transition process for the rotation of the middle lifting rod 5, making the overall transmission smoother. The problem of the lifting rod shaking of the original railway freight car coupler 9 caused by the overlapping structure is solved, and by optimizing the matching mode of the driving ring 11 and the driven ring 12, the structural stability is enhanced, meeting the requirements of subway engineering vehicles for the stability of the lifting rod of the coupler 9.

[0047] When the driving ring 11 slides relative to the driven ring 12, the driving ring 11 maintains its support for the driven ring 12 and the intermediate lifting rod 5. This ensures that during the relative sliding of the driving ring 11 and the driven ring 12, the intermediate lifting rod 5 can always be stably supported and will not shake or become unstable due to sliding, further ensuring the stability and reliability of the structure. Similarly, in order to address the shaking problem of the lifting rod of the original railway freight car coupler 9 caused by the overlapping structure, by strengthening the supporting role of the driving ring 11, the shaking of the lifting rod of the coupler 9 caused by the vibration of the vehicle operation is effectively solved, reducing the risk of triggering the uncoupling of the coupler 9.

[0048] The hook lock iron 10 is connected to the middle lifting rod 5 at intervals with the connecting line at both ends of the middle lifting rod 5, so that the hook lock iron 10 is connected to the middle lifting rod 5 and rotates around the rotation axis of the operating lifting rod 3, increasing the movement stroke of the middle lifting rod 5 driving the hook lock iron 10, and meeting the demand of the hook lock iron 10 to control the coupler 9. When the middle lifting rod 5 rotates, the hook lock iron 10 can perform the uncoupling and locking actions of the coupler 9 more smoothly, optimize the movement trajectory of the hook lock iron 10, and improve the accuracy of the uncoupling and locking operations of the coupler 9. The operation process of uncoupling and locking the coupler 9 is optimized, and compared with the possible inaccurate operation problem of the original railway freight car coupler 9 lifting rod, the operation performance of the double-sided coupler 9 uncoupling device is improved, and the demand for the accuracy of the operation of the coupler 9 of the subway engineering vehicle is met.

[0049] In this embodiment, Figure 1 As shown, the unhooking device of the double-sided acting coupler 9 adopts a three-stage structure, the driven ring 12 of the middle lifting rod 5 can adopt a nearly U-shaped structure, or a ring structure formed by closing the U-shaped opening position, and the driving ring 11 at the end of the operating lifting rod 3 can adopt a ring structure, so that the middle lifting rod 5 can only be driven by the operating lifting rod 3 driven by an external force to rotate to perform the unhooking operation. It is ensured that during the unhooking process, the middle lifting rod 5 will not drive the operating lifting rod 3 on the other side that is in a locked state to rotate. The driving ring 11 of the operating lifting rod 3 in a locked state forms an idling with the driven ring 12, which is not restricted, thereby effectively realizing the double-sided acting unhooking operation. The accuracy and independence of the operation are improved, and unnecessary interference between the lifting rods on both sides is avoided.

[0050] Compared with the prior art, the double-side acting coupler 9 unhooking device provided in this embodiment has fewer bends. Reducing the number of bends means that during the manufacturing process, the processing technology is simpler, the manufacturing difficulty is reduced, the production efficiency is improved, and the production cost is also reduced. The relatively simple structure is not only conducive to manufacturing, but also makes the installation and arrangement of the operating lifting rod 3 and the intermediate lifting rod 5 on the vehicle body more convenient, and occupies less space, which solves the problem of difficulty in arranging the coupler 9 lifting rod due to space limitations in subway engineering vehicles.

[0051] It should be pointed out that it is precisely because of the buckle matching structure of the driving ring 11 and the driven ring 12 that when one side of the operating lifting rod 3 is pulled, the other side of the operating lifting rod 3 will not rotate. This feature avoids the restriction of the unhooking operation by the lifting rod in the locked state on the other side, greatly reduces the operating pressure, reduces the difficulty of unhooking, and improves the working efficiency and operating experience of the operator.

[0052] Compared with the problems of the complex structure of the lifting rod of the coupler 9 for railway freight cars mentioned in the background technology, the difficulty in arranging it in the subway engineering vehicle, and the shaking of the lifting rod of the coupler 9, the double-side acting coupler 9 unhooking device in this embodiment effectively solves these problems through a unique structural design. Its simple structure and small space occupation overcome the space limitation problem caused by the impact seat and the driver's cab on the coupler 9 of the subway engineering vehicle; the precise driving and locking design avoids the shaking of the lifting rod of the coupler 9 caused by improper operation or unreasonable structure and the risk of triggering the unhooking of the coupler 9 caused by it.

[0053] like Figure 6 As shown, the baffle 7 of the anti-misoperation mechanism 1 has an L-shaped slide groove, which is also to prevent the baffle 7 from being misoperated. In actual use scenarios, people may accidentally touch the baffle 7 when operating surrounding equipment or performing other activities. If the baffle 7 is not designed properly, it may cause accidental movement, causing the unhooking device to be in an unexpected unlocked state, causing serious problems such as unhooking and connection failure. The L-shaped slide groove cooperates with the positioning pin 8 to increase the difficulty of accidental movement of the baffle 7, so that the baffle 7 will not be easily misoperated, thereby improving the reliability of the anti-misoperation mechanism 1.

[0054] When the unhooking operation is required, the staff needs to lift the baffle plate 7 and slide it to the end of the L-shaped slide groove, and then lift the operating lever 3 to realize the unhooking operation. This operation process design is equivalent to adding an extra safety line for the unhooking operation, which plays a secondary locking role. It avoids the risk of unhooking due to misoperation, ensures that unhooking can only be performed under the clear and correct operation of the staff, and greatly improves the safety of the unhooking operation of the coupler 9.

[0055] In view of the limited space of subway engineering vehicles, the buckle matching connection mode of the middle lifting rod 5 and the end lifting rod of this embodiment can effectively realize the double-sided unhooking operation without adopting the solution of setting a fixed support block mentioned in the prior art. It not only meets the space requirements of subway engineering vehicles, but also ensures the normal unhooking operation of the coupler 9, thereby improving the practicality of the device.

[0056] Example 2

[0057] In another typical embodiment of the present invention, Figure 1-Figure 6As shown, a working method of a double-side acting coupler 9 unhooking device is provided, using the double-side acting coupler 9 unhooking device as in Example 1.

[0058] A working method of a double-side acting coupler 9 unhooking device, comprising:

[0059] When unlocking the coupler 9, the operating lever 3 is controlled from the locomotive side to rotate the operating lever 3 to rotate the drive ring 11;

[0060] After the driving ring 11 idles for a set stroke, it forms a stable contact with the middle lifting rod 5, thereby driving the middle lifting rod 5 to rotate, so that the hook lock iron 10 unlocks the coupler 9;

[0061] When the coupler 9 is locked, the operating lever 3 is released and reset, and the hook lock iron 10 restores the locking state of the coupler 9.

[0062] When the hook lock iron 10 is unhooked by the operating lifting rod 3 on either side of the coupler 9, the operating lifting rod 3 on the other side keeps supporting the middle lifting rod 5.

[0063] It can be understood that the idling stroke is set according to the relative positions of the driving ring 11 and the driven ring 12. As the positions of the driving ring 11 and the driven ring 12 change, the abutment position of the driving ring 11 and the middle lifting rod 5 gradually approaches, while ensuring that the non-actively controlled operating lifting rod 3 on the other side remains in a state where rotation is not triggered.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
