Description

Technical Field

[0001] The invention relates to the technical field of coupler unhooking devices, in particular to a coupler unhooking device. Background Art

[0002] A coupler is a vehicle component used to connect a locomotive and a vehicle or between vehicles, to transmit traction and impact force, and to keep a certain distance between vehicles. Couplers are divided into upper-acting and lower-acting types according to the way they are opened. The upper-acting type is opened by the lifting mechanism on the upper part of the coupler head (most freight vehicles generally use this type); the lower-acting type is opened by the action of the push-up lever on the lower part of the coupler head (used on passenger cars). Couplers are divided into spiral couplers, close-fitting automatic couplers, automatic couplers and rotary couplers according to their structural types. Spiral couplers were the first to be used, but have been eliminated due to many shortcomings, and close-fitting automatic couplers are mostly used for high-speed railway vehicles. Except for the rotary couplers used on the heavy-duty unit trains of the Daqin Railway, China now uses automatic couplers. The so-called automatic coupler is a coupler that can automatically complete the action of unhooking or hooking after the lifting rod of a coupler is lifted first, and then the locomotive pulls the vehicle away or collides with the coupler of another vehicle.

[0003] For the existing couplers, station staff need to uncouple the two connected carriages after the vehicle enters the station. There are currently two ways of uncoupling: one is manual uncoupling used for ordinary passenger and freight trains, and the other is electrical control uncoupling used for high-speed trains.

[0004] According to the above-mentioned manual unhooking method of passenger trains, combined with the actual platform design, we know that the platform height in the prior art is consistent with the height of the train carriage, so as to facilitate passengers to get on and off the train. This also leads to a very small distance between the train and the platform. If an emergency situation requires the separation of the carriage, the operator has no operating space and can only unhook near the side track. Due to the proximity to the track, the operation is extremely dangerous. In order to ensure the safety and convenience of unhooking, we propose a unhooking device. Summary of the invention

[0005] Based on this, the object of the present invention is to provide a hook-removing device for a coupler to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a hook-off device for a coupler, comprising a carriage frame, a coupler body fixed to the outer wall of the carriage frame, and a clamping column arranged on the end face of the coupler body for controlling the connection state of the coupler body, a tilting rod is arranged above the coupler body and on the outside of the coupler body, and a cross bar is fixedly connected to the outer wall of one end of the tilting rod, a pedal is fixed to the outer wall of the cross bar, a support plate installed on the outer wall of the coupler body is arranged below the tilting rod and in the moving direction of the tilting rod, and a limiting block is also fixed on the outer wall of the coupler body in the moving direction of the tilting rod, and the outer wall of the end of the tilting rod is also slidably connected to a limiting plate fixed to the outer wall of the coupler body.

[0007] By adopting the above technical solution, the operator can be assisted to remove the hook conveniently and quickly, and it can be used even on the platform, which improves the convenience and safety of the hook removal operation.

[0008] The present invention is further configured such that a socket is provided on the top inner wall of the clamping column, and the inner wall of the socket is adapted to the outer wall of the tilting rod, a through hole for assisting the movement of the clamping column is provided on the outer side of the clamping column located inside the coupler body, a bottom plate is provided on the outer side of the clamping column, and a wiping portion is fixed to the inner side of the bottom plate close to the clamping column, a tooth wall is fixed on the outer wall of the clamping column, and one side of the tooth wall is meshingly connected with a driven gear installed on the end face of the coupler body.

[0009] By adopting the above technical solution, the clamping column can be wiped and cleaned, and the driven gear can be driven by the movement of the clamping column.

[0010] The present invention is further configured such that the end of the driven gear is connected to the first bevel gear via a one-way bearing, and one side of the first bevel gear is meshingly connected to the second bevel gear.

[0011] By adopting the above technical solution, a driving effect is achieved on the second bevel gear.

[0012] The present invention is further configured such that the bottom end of the second bevel gear is meshingly connected with a driven plate, and the outer wall of the driven plate is fixedly connected with a connecting rod connected to the outer wall of the bottom plate.

[0013] By adopting the above technical solution, a driving effect is achieved on the bottom plate.

[0014] The present invention is further configured such that a slide groove is provided on the end face of the coupler body, and a return spring is installed on the inner wall of the slide groove, the bottom end of the driven plate extends into the slide groove and is slidably connected to the inner wall of the slide groove, and the outer wall of the driven plate is connected to the return spring.

[0015] By adopting the above technical solution, the effect of assisting the movement of the driven plate is achieved, and at the same time the driven plate can be reset by itself.

[0016] In summary, the present invention mainly has the following beneficial effects:

[0017] The present invention uses a tilting rod, a support plate, a limit block, a limit plate and a pedal. When the coupler needs to be removed, the pedal is kicked forward by the foot, so that the pedal drives the cross bar and the tilting rod to move in the direction close to the coupler until the end of the tilting rod moves out of the limit plate and the cross bar moves to the end of the limit block and is limited. At this time, the end of the tilting rod is just inserted into the clamping column. Then, the pedal is pressed from top to bottom, and the pedal is rotated with the support plate as a fulcrum, so that the clamping column is tilted out of the coupler, and then the carriage can be separated. The above structure realizes the removal of the coupler conveniently and quickly, which not only improves the efficiency of the coupler removal, but also effectively improves the safety of the operation.

[0018] The present invention uses the wiping portion, the bottom plate, the tooth wall, the driven gear, the first bevel gear, the second bevel gear, the driven plate and the connecting rod. When the card column moves upward, the tooth wall of the outer wall drives the driven gear to rotate. Since the driven gear is connected to the first bevel gear through a one-way bearing, the first bevel gear does not rotate at this time. Therefore, when the card column moves out, the wiping portion wipes the outer wall of the card column, which has a cleaning effect on the card column, is beneficial to the maintenance of the card column and prolongs its service life. Further, when the card column moves downward, the driven gear rotates under the action of the tooth wall to drive the second bevel gear to rotate. When a bevel gear rotates, the first bevel gear drives the second bevel gear to rotate. After the second bevel gear rotates, it drives the driven plate to squeeze the reset spring and move. The movement of the driven plate drives the bottom plate to move through the connecting rod, which also drives the wiping part to move. Therefore, in the process of the card column moving downward, the wiping part moves away from the card column to avoid the resistance generated by the wiping part affecting the movement of the card column. After the card column is completely moved into the through hole, the tooth wall and the driven gear are disengaged. Therefore, the driven plate will be reset under the action of the reset spring and push the bottom plate through the connecting rod to drive the wiping part to reset.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] A hook-off device for a coupler, such as Figure 1-4 As shown, it includes a carriage outer frame 1, a coupler body 2 fixed on the outer wall of the carriage outer frame 1, and a clamping column 3 arranged on the end surface of the coupler body 2 for controlling the connection state of the coupler body 2. A plug hole is provided on the top inner wall of the clamping column 3, and the inner wall of the plug hole is adapted to the outer wall of the tilting rod 4. The outer side of the clamping column 3 is located inside the coupler body 2 and a through hole 10 for assisting the movement of the clamping column 3 is provided. A bottom plate 11 is provided on the outer side of the clamping column 3, and a wiping portion 12 is fixed on the inner side of the bottom plate 11 close to the clamping column 3. A tooth wall 13 is fixed on the outer wall of the clamping column 3, and one side of the tooth wall 13 is meshedly connected with a driven gear 14 installed on the end surface of the coupler body 2, so as to wipe and clean the outer wall of the clamping column 3 and prevent the accumulation of dust from causing aggravated wear of the clamping column 3. The upper part of the coupler body 2 and A tilting rod 4 is arranged on the outer side of the coupler body 2, and a cross bar 5 is fixedly connected to the outer wall of one end of the tilting rod 4, a pedal 6 is fixed to the outer wall of the cross bar 5, a support plate 7 installed on the outer wall of the coupler body 2 is arranged below the tilting rod 4 in the moving direction of the tilting rod 4, and a limiting block 8 is also fixed on the outer wall of the coupler body 2 in the moving direction of the tilting rod 4, and a limiting plate 9 fixed to the outer wall of the end of the tilting rod 4 is also slidably connected to the limit plate 9 fixed to the outer wall of the coupler body 2, the bottom end of the second bevel gear 16 is meshedly connected with a driven plate 17, and the outer wall of the driven plate 17 is fixedly connected with a connecting rod 18 connected to the outer wall of the bottom plate 11, the second bevel gear 16 will drive the driven plate 17 to move, and the movement of the driven plate 17 will then drive the connecting rod 18 to move, thereby realizing the driving effect on the bottom plate 11.

[0027] See also Figure 4 The end of the driven gear 14 is connected to the first bevel gear 15 through a one-way bearing, and one side of the first bevel gear 15 is meshedly connected to the second bevel gear 16 to drive the second bevel gear 16 left and right.

[0028] See also Figure 3-4A slide groove is provided on the end face of the coupler body 2, and a return spring is installed on the inner wall of the slide groove. The bottom end of the driven plate 17 extends into the inside of the slide groove and is slidably connected to the inner wall of the slide groove. The outer wall of the driven plate 17 is connected to the return spring to assist the movement of the driven plate 17 and enable the driven plate 17 to have the function of automatic resetting.

[0029] The working principle of the present invention is as follows: when the coupler body 2 needs to be removed, the pedal 6 is kicked forward by the foot, so that the pedal 6 drives the cross bar 5 and the lifting rod 4 to move in the direction close to the coupler body 2, until the end of the lifting rod 4 moves out of the limit plate 9, and the cross bar 5 moves to the end of the limit block 8 and is limited. At this time, the end of the lifting rod 4 is just inserted into the inside of the clamping column 3, and then the pedal 6 is pressed from top to bottom. At this time, the lifting rod 4 will rotate with the support plate 7 as the fulcrum, so that the clamping column 3 is lifted out of the coupler body 2, and then the car body outer frame 1 can be separated;

[0030] When the clamping column 3 is moved upward, the tooth wall 13 on its outer wall drives the driven gear 14 to rotate. Since the driven gear 14 is connected to the first bevel gear 15 through a one-way bearing, the first bevel gear 15 does not rotate at this time. Therefore, when the clamping column 3 is moved out, the wiping portion 12 wipes the outer wall of the clamping column 3, which has a cleaning effect on the clamping column, is beneficial to the maintenance of the clamping column and prolongs its service life.

[0031] Furthermore, when the column 3 moves downward, the driven gear 14 rotates under the action of the tooth wall 13, which will drive the first bevel gear 15 to rotate. The first bevel gear 15 thus drives the second bevel gear 16 to rotate. After the second bevel gear 16 rotates, it will drive the driven plate 17 to squeeze the reset spring and move. The movement of the driven plate 17 will drive the bottom plate 11 to move through the connecting rod 18, and also drive the wiping portion 12 to move. Therefore, in the process of the column 3 moving downward, the wiping portion 12 moves away from the column 3 to avoid the resistance generated by the wiping portion 12 affecting the movement of the column 3. After the column 3 is completely moved into the through hole 10, the tooth wall 13 and the driven gear 14 are disengaged. Therefore, the driven plate 17 will be reset under the action of the reset spring and push the bottom plate 11 through the connecting rod 18 to drive the wiping portion 12 to reset.
