Description

Technical Field

[0001] The present invention belongs to the technical field of railway vehicle coupler unlocking, and more particularly, relates to a coupler uncoupling rod mounting seat, an uncoupling rod mounting assembly and a railway vehicle. Background Art

[0002] Railway freight cars must be assembled into trains before running. Currently, most railway freight cars are connected using 13B and 17 type down-acting couplers. These two types of down-acting couplers have a small connection gap, which can reduce the longitudinal impulse between cars. At the same time, this type of down-acting coupler is made of E-grade cast steel, and the coupler is strong enough to meet the needs of the formation of 10,000-ton trains. This down-acting coupler uses a manually rotated uncoupling lever to drive the lower locking pin to form a push-on coupler lock and the coupler tongue pushes the iron to open the coupler tongue and complete the uncoupling operation. The uncoupling lever of this type of down-acting coupler is used in conjunction with an uncoupling lever mounting base with a keyhole. The existing uncoupling lever mounting base and uncoupling lever have the following problems in use:

[0003] like Figure 1 As shown, the uncoupling rod 6 in the uncoupling rod mounting seat should normally be positioned at the bottom of the keyhole. After the flat part of the uncoupling rod falls into the lower part of the keyhole of the uncoupling rod mounting seat, when the vehicle enters and exits the curve, the coupler will swing left and right. During the swinging process, the uncoupling rod 6 will slide and swing left and right relative to the uncoupling rod mounting seat. Since the gap between the flat part of the uncoupling rod 6 and the lower end of the keyhole of the uncoupling rod mounting seat is small, the coupler swings left and right while the uncoupling rod is stuck, causing the uncoupling rod to be stretched and compressed and deformed. The deformed uncoupling rod has a poor unhooking function or even fails, seriously affecting the normal operation of the vehicle. Since the existing uncoupling rod 6 in the keyhole of the uncoupling rod mounting seat is a straight up and down vertical movement process from the non-working position to the working position, the assembly gap between the two needs to be controlled within 3mm. If the gap is too small, it is easy to cause jamming. When the gap is increased, such as Figure 2 As shown, during operation, individual unhooking rods may jump vertically upwards into the circular hole at the upper end of the keyhole due to the bumping and vibration of the vehicle, posing a driving safety hazard of accidental unhooking and separation. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies in the prior art and provide a coupling uncoupling rod mounting seat to solve the problems in the prior art of the coupling between the uncoupling rod and the uncoupling rod mounting seat, such as the uncoupling rod being easily deformed when the railway vehicle enters or exits a curved line, and the uncoupling rod having the risk of jumping up when the railway vehicle is bumped or vibrated.

[0005] In order to achieve the above-mentioned object, the present invention provides a coupling uncoupling rod mounting seat, comprising:

[0006] A vertical plate and a mounting plate, the mounting plate is connected to one end of the vertical plate to form a T-shaped structure, a keyhole is provided at one end of the vertical plate away from the mounting plate, the keyhole includes a rotating hole and a limiting hole arranged in sequence from top to bottom and connected to each other, the rotating hole can accommodate the unhooking rod to rotate therein, the limiting hole is used to limit the unhooking rod to rotate therein, a lateral groove is provided at the lower end of one side hole wall of the limiting hole, and when the unhooking rod is in place, part of the unhooking rod is in the lateral groove.

[0007] Optionally, a slope portion is provided at the lower end of the other side hole wall of the limiting hole, and the slope portion gradually becomes thinner from away from the lateral groove toward the lateral groove, and a landing groove for the unhooking rod is formed between the slope portion and the lateral groove.

[0008] Optionally, the upper end groove wall of the lateral groove is provided with a gradually expanding groove from bottom to top.

[0009] Optionally, the vertical plate includes a fixed portion and an opening and closing portion, the opening and closing portion is connected to the fixed portion in an opening and closing manner, the opening and closing portion forms part of the hole wall of the rotating hole, and when the opening and closing portion is opened, a gap is formed in the hole wall of the rotating hole, and the gap can accommodate the unhooking rod to pass through.

[0010] Optionally, one end of the opening and closing portion is rotatably connected to the fixing portion via a rotating shaft, and the other end of the opening and closing portion is connected to the fixing portion via a detachable pin.

[0011] Optionally, the width of the lateral groove is 4-5 mm.

[0012] Optionally, the rotation hole is a circular hole, and the seating groove is eccentrically arranged relative to the rotation hole.

[0013] The present invention also provides an unhooking rod installation assembly, comprising:

[0014] an unhooking rod, the unhooking rod comprising a round rod portion and a rectangular rod portion disposed in the middle of the round rod portion;

[0015] In the above-mentioned uncoupling rod mounting seat of the coupler, the rectangular rod portion passes through the keyhole.

[0016] Optionally, when the unhooking rod is in place, part of the rectangular rod portion is located in the lateral groove.

[0017] The present invention also provides a railway vehicle, comprising the above-mentioned uncoupling rod installation assembly.

[0018] The present invention provides a coupling uncoupling rod mounting seat, an uncoupling rod mounting assembly and a railway vehicle, the beneficial effects of which are as follows: the vertical plate of the coupling uncoupling rod mounting seat is mounted on the railway vehicle through the mounting plate, the uncoupling rod passes through the keyhole on the vertical plate, the rotating hole at the upper end of the keyhole accommodates the uncoupling rod to rotate therein to meet the operation requirements of unlocking the coupler, and the limiting hole at the lower end of the keyhole limits the rotation of the uncoupling rod to prevent the uncoupling rod from rotating in the limiting hole and causing the coupler to be locked incorrectly. The lateral groove can accommodate part of the uncoupling rod when the uncoupling rod is in place, so that the uncoupling rod is biased to one side in the limiting hole when it is in place. The setting of the lateral groove makes the limiting hole, which originally has a small gap with the uncoupling rod, wider, and the gap between it and the uncoupling rod becomes larger.

[0031] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0032] like Figure 3 As shown, the present invention provides a coupling uncoupling rod mounting seat, comprising:

[0033] The vertical plate 1 and the mounting plate 2, the mounting plate 2 is connected to one end of the vertical plate 1 to form a T-shaped structure, and a keyhole is opened at the end of the vertical plate 1 away from the mounting plate 2. The keyhole includes a rotating hole 3 and a limiting hole 4 arranged and connected in sequence from top to bottom. The rotating hole 3 can accommodate the unhooking rod 6 to rotate inside it, and the limiting hole 4 is used to limit the rotation of the unhooking rod 6 inside it. A lateral groove 5 is provided at the lower end of the hole wall on one side of the limiting hole 4. When the unhooking rod 6 is in place, part of the unhooking rod 6 is in the lateral groove 5.

[0034] Specifically, in order to solve the problems in the prior art that the uncoupling rod 6 and the uncoupling rod mounting seat are easily deformed when the railway vehicle enters or exits a curved line, and the uncoupling rod 6 has the hidden danger of jumping up when the railway vehicle is bumped and vibrated, the vertical plate 1 of the uncoupling rod mounting seat of the coupler provided by the present invention is installed on the railway vehicle through the mounting plate 2, and the uncoupling rod 6 passes through the keyhole on the vertical plate 1. The rotating hole 3 at the upper end of the keyhole accommodates the uncoupling rod 6 to rotate inside it to meet the operational requirements of unlocking the coupler, and the limiting hole 4 at the lower end of the keyhole limits the rotation of the uncoupling rod 6 to prevent the uncoupling rod 6 from rotating in the limiting hole 4 and causing the coupler to be unlocked. In case of misunderstanding, the lateral groove 5 provided at the lower end of the hole wall on one side of the limiting hole 4 can accommodate part of the uncoupling rod 6 when the uncoupling rod 6 is in place, so that the uncoupling rod 6 is biased to one side in the limiting hole 4 when it is in place. The setting of the lateral groove 5 makes the limiting hole 4, which originally has a small gap with the uncoupling rod 6, widen, and the gap between it and the uncoupling rod 6 becomes larger. This can avoid the deformation of the uncoupling rod 6 caused by the left and right swinging and pulling of the coupler when the railway vehicle enters and exits the curved cable. At the same time, the upper end wall of the lateral groove 5 will produce a vertical limiting effect on the uncoupling rod 6 in the placed state, avoiding the safety hazard of the uncoupling rod 6 jumping up and accidentally opening the coupler when the railway vehicle is bumped and vibrated.

[0035] In this embodiment, the mounting plate 2 on one side of the vertical plate 1 is similar to the mounting plate 2 on the uncoupling rod mounting seat in the prior art. It is integrally connected to the vertical plate 1, and there are mounting holes on both sides of the vertical plate 1 for installation on the body 17 of the railway vehicle.

[0036] In this embodiment, the rotating hole 3 of the keyhole is a circular hole, the limiting hole 4 is a rectangular hole connected to the lower end of the circular hole, and the lateral groove 5 is a rectangular groove opened on one side of the rectangular hole to partially widen the rectangular hole.

[0037] Optionally, a slope portion 7 is provided at the lower end of the hole wall on the other side of the limiting hole 4 , and the slope portion 7 gradually becomes thinner from away from the lateral groove 5 toward the lateral groove 5 , and a landing groove for the unhooking rod 6 is formed between the slope portion 7 and the lateral groove 5 .

[0038] Specifically, the slope portion 7 is arranged inside the corner of the lower end of the hole wall on the other side of the limiting hole 4. The bevel portion makes the bottom of the limiting hole 4 higher at the end away from the lateral groove 5 and lower at the end close to the lateral groove 5, so that the unlocking rod can slide down the slope portion 7 into the lateral groove 5 by its own weight. Figure 4 As shown, a fully seated state is formed.

[0039] In this embodiment, when the uncoupling rod 6 is in place, the center of the uncoupling rod 6 in the seating groove forms a left-right offset with the center of the rotating hole 3. When the uncoupling rod 6 is fully in place, the uncoupling rod mounting seat assembly has a gap of about 7 mm with it. When the railway vehicle enters and exits a curve, the left and right swing of the coupler can easily drive the uncoupling rod 6 to slide left and right relative to the coupler uncoupling rod 6 seat, avoiding the problem that the gap between the existing uncoupling rod mounting seat and the uncoupling rod 6 is small, which easily causes the uncoupling rod 6 to be stuck and cause deformation or breakage. At the same time, when the uncoupling rod 6 is fully in place, since the center of the uncoupling rod 6 is offset from the center of the rotating hole 3, when the uncoupling rod 6 jumps upward and hits the groove wall at the upper end of the lateral groove 5, it is blocked, preventing it from jumping further upward, and as the uncoupling rod 6 falls completely into the positioning groove again under the action of its own weight and along the slope 7; during the bumpy and vibrating process of the railway vehicle running, the uncoupling rod 6 will be blocked as long as it automatically jumps upward, so the design avoids the accidental uncoupling failure caused by the uncoupling rod 6 in the existing uncoupling rod mounting seat jumping upward, and since the uncoupling rod 6 at the lower end of the keyhole is an eccentric structure relative to the rotating hole 3, the wear limit of the uncoupling rod mounting seat and the uncoupling rod 6 can be relaxed, which can extend the maintenance cycle and service life of the accessory, and further reduce the maintenance cost throughout the life cycle.

[0040] In this embodiment, the shape and size of the seating groove match the shape and size of the unhooking rod 6 located therein, and the unhooking rod 6 is located exactly in the seating groove when in position.

[0041] Optionally, the upper end wall of the lateral groove 5 is provided with a gradually expanding groove 8 from bottom to top.

[0042] Specifically, the groove is opened on the upper end wall of the lateral groove 5, and gradually expands from the groove bottom of the lateral groove 5 toward the limiting hole 4. When the unhooking rod 6 moves upward into the rotating hole 3, it can provide a guiding effect to facilitate operation.

[0043] In this embodiment, the slope angle of the gradually expanding groove 8 is set according to actual conditions, so that it has both a guiding function and a good limiting function for the unhooking rod 6.

[0044] Optionally, the vertical plate 1 includes a fixed part and an opening and closing part 9, and the opening and closing part 9 is connected to the fixed part in an opening and closing manner. The opening and closing part 9 forms part of the hole wall of the rotating hole 3. When the opening and closing part 9 is opened, a notch 10 is formed in the hole wall of the rotating hole 3, and the notch 10 can accommodate the unhooking rod 6 to pass through.

[0045] Specifically, the opening and closing portion 9 is arranged so that when it is opened, a notch 10 is formed on the wall of the rotating hole 3 for the unhooking rod 6 to pass through, thereby facilitating the unhooking rod 6 to be removed from the unhooking rod mounting seat for easy maintenance.

[0046] The existing uncoupling rod mounting base needs to be spot welded after assembly to form a stable connection with the railway vehicle body 17. When the uncoupling rod 6 needs to be repaired or replaced, the uncoupling rod 6 needs to be removed. The operation process is to first use a flame cutting torch to burn the spot-welded mounting bolts and nuts, and then remove the uncoupling rod mounting base to remove the uncoupling rod 6, which takes a long time to disassemble and is complicated. This maintenance operation is easy to implement in temporary repair or station repair workshops, but it is difficult to repair the faulty uncoupling rod 6 in a timely manner when the vehicle does not have a cutting torch equipment and the train inspection time is limited. At this time, the vehicle can only operate with the fault, which brings difficulties to the next step of marshaling and uncoupling of the vehicle. At the same time, if the uncoupling rod 6 deforms and fails, it is more likely to cause the horizontal deflection of the coupler to be blocked when the vehicle passes through a curve, further affecting the curve passing performance of the vehicle, and bringing a traffic safety hazard to the vehicle when running on a curved line. Therefore, the provision of the opening and closing portion 9 can solve the problem that it is difficult to conveniently disassemble and repair the uncoupling rod 6 when a fault affects the uncoupling function during the operation of the railway vehicle.

[0047] Optionally, one end of the opening and closing portion 9 is rotatably connected to the fixed portion via a rotating shaft 11 , and the other end of the opening and closing portion 9 is connected to the fixed portion via a detachable pin 12 .

[0048] Specifically, such as Figure 5 As shown, the opening and closing portion 9 is arc-shaped, one end of which is rotatably connected to the fixed portion through a rotating shaft 11, and the other end is penetrated by a pin 12. The pin 12 can be a big-headed pin with a hole. After passing through the pin hole on the fixed portion, a gasket 13 is placed and a cotter pin 14 is inserted to fix it; when the unhooking rod 6 needs to be removed, the opening and closing portion 9 is opened, and the unhooking rod 6 can be easily taken out.

[0049] Optionally, the width of the lateral groove 5 is 4-5 mm.

[0050] Specifically, the width of the lateral groove 5 should not be too large to ensure that the position of the limit hole 4 has a limiting effect on the rotation of the uncoupling rod 6, so that its rotation amplitude is less than the set value to avoid accidental uncoupling. At the same time, it should not be too small. If it is too small, the effect of avoiding the deformation of the uncoupling rod 6 caused by the left and right swinging and pulling of the coupler when the railway vehicle enters and exits the curved cable and avoiding the safety hazard of the uncoupling rod 6 jumping up when the railway vehicle is bumped and vibrated, which may cause the uncoupling rod to accidentally open, will be poor.

[0051] Optionally, the rotating hole 3 is a circular hole, and the landing groove is eccentrically arranged relative to the rotating hole 3.

[0052] Specifically, the landing groove is biased to one side relative to the rotating hole 3, thereby avoiding the problem of deformation of the uncoupling rod 6 caused by the small gap between the keyhole of the existing uncoupling rod mounting seat and the uncoupling rod 6, and the problem of the uncoupling rod 6 accidentally jumping upward under the influence of the bumpy vibration of the railway vehicle, which poses a hidden danger to driving safety.

[0053] like Figure 6 and Figure 7 As shown, the present invention also provides an unhooking rod installation assembly, comprising:

[0054] The unhooking rod 6 includes a round rod portion 15 and a rectangular rod portion 16 disposed in the middle of the round rod portion 15;

[0055] The above-mentioned unhooking rod mounting seat of the coupler has a rectangular rod portion 16 passing through the keyhole.

[0056] Specifically, the portion of the uncoupling lever 6 that passes through the keyhole is a rectangular rod portion 16 , which can be restricted in rotation by the limiting hole 4 . The uncoupling lever 6 can be rotated to unlock the coupler only when it is lifted into the rotating hole 3 .

[0057] Optionally, when the unhooking rod 6 is in place, part of the rectangular rod portion 16 is located in the lateral groove 5 .

[0058] Specifically, such as Figure 6 As shown in FIG, when the railway vehicle encounters bumps and vibrations during operation, the uncoupling rod 6 will be blocked by the upper end groove wall of the lateral groove 5 as long as it jumps upward, thus avoiding the accidental uncoupling failure caused by the uncoupling rod 6 in the existing uncoupling rod mounting seat automatically jumping upward; Figure 7 As shown, when the unhooking rod 6 is blocked from jumping vertically upward, when it wants to continue to deviate to the left and jump to reach the hole wall on the other side of the limiting hole 4, it will be hindered by the friction resistance between the unhooking rod 6 and the slope 7 of the unhooking rod mounting seat and the weight of the unhooking rod 6 during this rising process. Since the automatic jumping of the unhooking rod 6 during driving is only a temporary and sudden instantaneous action, there will be no continuous upward force to push the unhooking rod 6 to jump continuously upward. Therefore, the friction resistance between the slope 7 and the unhooking rod 6 and the weight will limit the continuous upward jumping of the unhooking rod 6 and cause the hidden danger of unhooking.

[0059] like Figure 8 As shown, the present invention also provides a railway vehicle, comprising the above-mentioned uncoupling rod installation assembly.

[0060] Specifically, in the above-mentioned uncoupling rod mounting assembly, the uncoupling rod mounting seat of the coupler is installed on the vehicle body 17 through the mounting plate 2, and the uncoupling rod 6 is inserted into the keyhole. When in the positioned state, the rectangular rod portion 16 of the uncoupling rod 6 is stuck in the limiting hole 4 to limit its rotation and avoid accidental opening of the coupler. When unlocking is required, the uncoupling rod 6 can be lifted upward to enter the rotating hole 3, so that it can be rotated and the coupler can be opened.

[0061] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
