Technical Field

[0001] The present invention belongs to the technical field of EMU sliding plug door disassembly, and more specifically, relates to a EMU sliding plug door disassembly device. Background Art

[0002] The plug door has two main actions: plugging and pulling. When the door is closed, it is plugged into the door opening from inside or outside the car to form a closed and airtight seal; when the door is opened, after the door is moved a certain distance away from the door opening, it can slide along the inside or outside of the car body. The plug doors of railway passenger cars are divided into two types: inner plug doors and outer plug doors, which are plugged into the door opening from inside or outside the car respectively.

[0003] The upper cover of the high platform flap of the plug door is connected by bolts, and a stainless steel buckle cover is connected to the upper cover by a connector as decoration. Because it is often eroded by wind and rain, when removing the buckle cover, the connector is difficult to remove effectively due to rust, and it is necessary to use a disassembly tool to disassemble it, so as to open the buckle cover and the upper cover and inspect the inside of the flap. Most existing disassembly tools achieve the matching with the part to be disassembled by setting a matching groove on the handle. Since the matching groove is mostly exposed, it is easy to cause damage and cracking of the handle due to external bumps, which will affect the inspection and maintenance of the EMU plug door.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0020] Please also read Figures 1 to 3 The EMU plug sliding door disassembly device provided by the present invention is now described. The EMU plug sliding door disassembly device comprises a housing 1, an operating handle 2, a sliding block 3 and a transmission rod group 4. The lower end of the operating handle 2 is hinged to the upper end of the housing 1. The sliding block 3 is connected to the housing 1 by sliding along the axial direction of the housing 1. The sliding block 3 is provided with a matching groove 32 that passes through from top to bottom. The transmission rod group 4 is connected between the operating handle 2 and the sliding block 3. The operating handle 2 can swing vertically to drive the sliding block 3 to move downward along the axial direction of the housing 1 to protrude from the lower end surface of the housing 1 with the help of the transmission rod group 4.

[0021] Compared with the prior art, the EMU plug door disassembly equipment provided by the present embodiment installs the sliding block 3 in the shell 1 to protect the sliding block 3, and utilizes the vertical swing of the operating handle 2 to drive the transmission rod group 4 to swing, thereby driving the sliding block 3 to move downward, so that the sliding block 3 extends out from the bottom of the shell 1, so that it is convenient to cooperate with the connecting part to be disassembled through the matching groove 32, thereby realizing the disassembly of the connecting part, avoiding structural damage caused by the matching groove 32 being in an exposed state for a long time, improving the disassembly efficiency, and meeting the maintenance needs of the plug door.

[0022] In this embodiment, when the Sierra door needs to be disassembled, the operating handle 2 is pressed down to utilize the transmission rod group 4 to drive the sliding block 3 to move downward and extend from the bottom of the shell 1. At this time, the matching groove 32 of the sliding block 3 can form a contact and match with the connecting piece to be disassembled, and the connecting piece can be disassembled by driving the shell 1 to achieve the screwing and disassembly of the connecting piece, thereby avoiding the long-term exposure of the matching groove 32 to cause collision with other components and avoid structural damage, thereby ensuring the effective disassembly of the Sierra door and improving the subsequent maintenance efficiency.

[0023] The operating handle 2 can be in a circular cross section, a rectangular cross section or other cross section forms, as long as it can satisfy the driving function of the transmission rod group 4. The transmission rod group 4 should meet the driving requirements of the sliding block 3 and can drive the sliding block 3 to move axially along the housing 1. The matching groove 32 on the sliding block 3 is arranged toward the axial side of the housing 1, and the matching groove 32 is arranged through along the sliding direction of the sliding block 3, and can effectively engage with the connecting piece to be disassembled, and the connecting piece can be effectively disassembled by driving the housing 1 or the operating handle 2.

[0024] Specifically, a guide mechanism is provided between the sliding block 3 and the housing 1 to ensure the stability of the circumferential position of the sliding block 3 during the sliding process, so as to avoid affecting the normal movement function of the sliding block 3 due to the circumferential rotation. The guide mechanism includes a slide groove provided on the inner wall of the housing 1 and a slide table provided on the outer periphery of the sliding block 3, and the slide table is slidably connected in the slide groove to realize the circumferential limit function of the sliding block 3 during the sliding process.

[0025] In one possible implementation, please also refer to Figures 1 to 3 A mounting seat 11 protruding toward the outer circumference and used for mounting the operating handle 2 is provided on the upper part of one side of the shell 1. The lower end of the operating handle 2 is hinged on the mounting seat 11. A side of the shell 1 away from the mounting seat 11 is provided with a yield groove 12 with an opening upward for the operating handle 2 to swing vertically downward. A first adsorption seat 13 for adsorbing the peripheral wall of the operating handle 2 is provided on the inner side wall of the mounting seat 11, and a second adsorption seat 14 for adsorbing the peripheral wall of the operating handle 2 is provided on the bottom wall of the yield groove 12.

[0026] In this embodiment, in order to facilitate the installation of the operating handle 2, a mounting seat 11 is provided outside the housing 1. The operating handle 2 is hinged to the mounting seat 11 through a hinge shaft 15, so as to make full use of the space outside the housing 1 and avoid position interference with other components during the up and down swinging of the operating handle 2.

[0027] On this basis, the operating handle 2 has two extreme states, corresponding to the use state and non-use state of the disassembly device. Figures 1 to 3 The main axis of the operating handle 2 is arranged parallel to the main axis of the shell 1 (that is, it extends in the up and down direction). At this time, the sliding block 3 is in a state of being retracted in the shell 1, and the shell 1 is used to protect the sliding block 3 and the matching groove 32.

[0028] When the disassembly device is in use, the operating handle 2 is swung downward until the main axis is perpendicular to the main axis of the shell 1 (that is, it extends in the horizontal direction). At this time, the sliding block 3 is in a state of extending outward from the shell 1, and the matching groove 32 of the sliding block 3 is used to cooperate with the connecting piece to be disassembled to achieve effective disassembly of the component.

[0029] On this basis, the first adsorption seat 13 and the second adsorption seat 14 can be used to adsorb and limit the position of the operating handle 2 after it swings to a certain amplitude. The adsorption effect of the above structure can be in different forms such as vacuum adsorption, magnetic adsorption, and electromagnetic adsorption to meet the need for fixing the position of the operating handle 2.

[0030] In some embodiments, please refer to Figures 1 to 3 The first adsorption seat 13 has a first arc-shaped cavity 131 which is arranged toward the axial side of the shell 1 and contacts and cooperates with the peripheral wall of the operating handle 2, and the first arc-shaped cavity 131 extends in the up-down direction; the second adsorption seat 14 has a second arc-shaped cavity 141 which is opened upward and contacts and cooperates with the peripheral wall of the operating handle 2, and the second arc-shaped cavity 141 is arranged to penetrate the shell 1 in the radial direction.

[0031] In this embodiment, the operating handle 2 can be a cylindrical member, the first adsorption seat 13 is arranged on the mounting seat 11, and the first arc-shaped cavity 131 on the first adsorption seat 13 extends in the up-down direction. When the disassembly device is in a non-use state (the operating handle 2 is in a vertical position), the inner cavity wall of the first arc-shaped cavity 131 is used to adsorb and limit the operating handle 2, so as to meet the requirement that the sliding block 3 is retracted in the housing 1.

[0032] The second adsorption seat 14 is arranged in the yield groove 12 on the side wall of the shell 1, and the second adsorption seat 14 is opened upward. When the disassembly device is in use (the operating handle 2 is in a horizontal position), the inner wall of the first arc-shaped cavity 131 and the surrounding wall of the operating handle 2 are effectively adsorbed to keep the position of the operating handle 2 stable while meeting the extension requirements of the sliding block 3.

[0033] The setting of the first adsorption seat 13 and the second adsorption seat 14 can ensure the reliable locking of the operating handle 2 between the two different states in the vertical direction and the horizontal direction, thereby effectively locking the position of the sliding block 3 in the shell 1, meeting the matching requirements between the matching groove 32 and the connecting part to be disassembled, and improving the convenience of operation.

[0034] In some embodiments, please refer to Figures 1 to 3 The bottom wall of the make way groove 12 is arc-shaped, the second adsorption seat 14 is connected to the bottom wall of the make way groove 12, the operating handle 2 is a steel component, and the first adsorption seat 13 and the second adsorption seat 14 are magnets.

[0035] In this embodiment, the shape of the clearance groove 12 matches the shape of the peripheral wall of the operating handle 2, which facilitates the installation of the second adsorption seat 14. The second adsorption seat 14 is an arc-shaped plate-shaped component, and the outer bottom wall of the second adsorption seat 14 is reliably connected to the bottom wall of the clearance groove 12, ensuring the reliability of the installation of the second adsorption seat 14.

[0036] The operating handle 2 is made of steel, and can form a reliable attraction with the first adsorption seat 13 and the second adsorption seat 14 made of magnetic material, meeting the limit requirements of the operating handle 2, and also ensuring the stability of the sliding block 3 when it is in different telescopic positions.

[0037] In one possible implementation, please also refer to Figures 1 to 3 The mounting base 11 includes a supporting plate 111 and a side plate 112. The supporting plate 111 is horizontally connected to the outer side of the shell 1. The side plate 112 is connected to the outer edge of the supporting plate 111 and extends upward. The first adsorption seat 13 is connected to the inner wall of the side plate 112. The operating handle 2 is hinged to the supporting plate 111 through a hinge shaft 15, and the hinge shaft 15 is arranged perpendicular to the main axis of the shell 1.

[0038] In this embodiment, the mounting base 11 is in the form of a combination of a supporting plate 111 and a side plate 112. The plate surface of the supporting plate 111 is perpendicular to the main axis of the shell 1, and the side plate 112 is arranged perpendicular to the supporting plate 111. The first adsorption component is installed on the inner wall of the side plate 112 and can be effectively adsorbed with the surrounding wall of the operating handle 2.

[0039] The support plate 111 is used to set the hinge shaft 15, which can be installed on the support plate 111 through the shaft seats at both ends, or connected to the support plate 111 through the middle column. The lower end of the operating handle 2 can be provided with a shaft sleeve that can be sleeved on the hinge shaft 15 to meet the swing requirements of the operating handle 2.

[0040] In one possible implementation, please also refer to Figures 1 to 3 The transmission rod group 4 includes a first connecting rod 41 and a second connecting rod 42. One end of the first connecting rod 41 is hinged to the side of the operating handle 2, and the other end is hinged to the upper end of the second connecting rod 42. The lower end of the second connecting rod 42 is hinged to the top of the sliding block 3. Under the action of the operating handle 2, the first connecting rod 41 can drive the second connecting rod 42 to swing vertically and push the sliding block 3 downward.

[0041] In this embodiment, the transmission rod group 4 is in the form of a combination of a first connecting rod 41 and a second connecting rod 42. When the operating handle 2 swings downward, one end of the first connecting rod 41 follows the operating handle 2 to swing downward, and the other end drives the upper end of the second connecting rod 42 to swing outward and downward. At this time, the lower end of the second connecting rod 42 drives the sliding block 3 to move downward synchronously, so that the sliding block 3 can smoothly extend downward from the lower end of the shell 1, so that it is convenient to interact with the connecting piece to be disassembled with the help of the matching groove 32 of the sliding block 3.

[0042] In one possible implementation, please also refer to Figures 1 to 3The outer end of the operating handle 2 is provided with an anti-slip sleeve 21, and the side of the operating handle 2 is provided with a limit plate 22 located below the first connecting rod 41. The plate surface of the limit plate 22 is arranged perpendicular to the main axis of the operating handle 2. When the operating handle 2 swings vertically upward, the limit plate 22 can be pressed against the bottom of the first connecting rod 41 to drive the second connecting rod 42 to swing and move upward.

[0043] In this embodiment, an anti-skid sleeve 21 is provided on the outer periphery of the operating handle 2, and a plurality of anti-skid grooves extending circumferentially are provided on the anti-skid sleeve 21, so as to increase the friction force and prevent the operator from slipping during operation. The setting of the limit plate 22 can limit the swing amplitude of the first connection. After use, the first connecting rod 41 is driven to swing by the upward swing of the operating handle 2. At this time, subject to the limiting effect of the limit plate 22, the first connecting rod 41 can only swing upward and form an upward pulling effect on the second connecting rod 42, ensuring the upward driving effect on the sliding block 3, so that the sliding block 3 can be smoothly retracted into the housing 1, forming an effective protection for the matching groove 32. The setting of the limit plate 22 ensures the driving effect of the first connecting rod 41 on the second connecting rod 42, and improves the effectiveness of the sliding action of the sliding seat.

[0044] In some embodiments, please refer to Figures 1 to 3 The top of the sliding block 3 is provided with a connection seat 31 hinged to the lower end of the second connecting rod 42, and the connection seat 31 extends toward the axis side close to the housing 1. A rotating shaft component is conveniently installed on the connection seat 31 to form a hinged effect with the lower end of the second connecting rod 42. The connection seat 31 extends toward the axis side close to the housing 1, so that the second connecting rod 42 is as far away from the inner circumferential wall of the housing 1 as possible, avoiding the position interference between the second connecting rod 42 and the inner wall of the housing 1 during the subsequent swinging process, thereby improving the stability and reliability of the structural operation.

[0045] In one possible implementation, please also refer to Figures 1 to 3 In a possible implementation, the EMU plug door disassembly device also includes a moisture-proof component 5 connected to the interior of the shell 1, and the moisture-proof component 5 includes an adsorption cotton 51 extending into the matching groove 32 of the sliding block 3.

[0046] In this embodiment, a moisture-proof component 5 is also provided in the shell 1, and the moisture-proof component 5 is used to effectively absorb the moisture inside the shell 1, so as to form a good dry environment, prevent the sliding block 3 from getting damp and rusting, and ensure the normal use of the structure.

[0047] In some embodiments, please refer to Figures 1 to 3The moisture-proof component 5 also includes a connecting plate 52 and a connecting column 53. The connecting plate 52 is connected to the inner wall of the shell 1 and is located above the sliding block 3. The plate surface of the connecting plate 52 is arranged perpendicular to the main axis of the shell 1. The connecting column 53 is connected to the bottom of the connecting plate 52 and corresponds to the matching groove 32 up and down. The adsorption cotton 51 is connected to the lower end of the connecting column 53.

[0048] In this embodiment, the adsorbent cotton 51 is connected to the inner wall of the housing 1 through the connecting plate 52 and the connecting column 53. The adsorbent cotton 51 is installed through the above structure to form a structural avoidance of the sliding block 3. The connecting plate 52 extends in the horizontal direction, and the connecting column 53 is located at the position of the connecting plate 52 close to the axis of the housing 1, so that the adsorbent cotton 51 can be smoothly extended into the matching groove 32 of the sliding block 3, so as to achieve effective adsorption of internal moisture, meet good drying performance, and avoid rust on the inner wall of the matching groove 32 to affect use.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
