Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of subway train maintenance, and particularly relates to a tool and method for adjusting the up-and-down swing-out distance of an electric sliding plug door leaf. BACKGROUND

[0002] At present, the door system commonly used in domestic subway trains includes sliding plug doors, externally-hung doors and internally-hung doors. The electric sliding plug door occupies nearly 80% of the market share due to its excellent performance and wide application, and becomes the first choice for urban rail transit vehicles. The electric sliding plug door is a door structure with a special movement form and opening and closing state, in which the door leaf runs along the guide rail, is parallel to the vehicle body in the opening state, and is flush with the side wall of the vehicle body and closely adheres to the side wall in the closing state.

[0003] When the vehicle maintenance personnel replace the lower swing arm of the sliding plug door leaf or adjust the up-and-down swing-out distance of the door leaf, the work needs to be performed in the opening state of the door, and a certain distance between the door leaf and the outer wall of the vehicle body should be ensured. In the adjustment process, the distance between the door lower slide and the roller should also be considered, and should be within a reasonable range. Taking the adjustment of the lower swing-out distance of the door leaf as an example, it is specified in the adjustment process that: "the door is opened to the fully opened position, one maintenance worker A loosens two lower swing arm mounting nut with a wrench, and another maintenance worker B moves the door leaf with his hand to move the swing arm forward and backward. The maintenance worker A measures the swing-out gap value using a steel tape measure, and the maintenance worker B needs to move the door leaf to make the distance between the outer surface of the door leaf and the door sill sealing surface satisfy 60-71mm, and then moves the swing arm up and down to adjust the gap between the bottom surface of the door lower slide and the upper surface of the lower swing arm. The maintenance worker A pre-tightens the two lower swing arm mounting nuts, and checks whether the data and state of the swing arm satisfy the requirements. If not, the above steps are repeated until the requirements are satisfied". At present, the vehicle maintenance personnel adjust the up-and-down swing-out distance of the sliding plug door leaf according to the above requirements.

[0004] According to the above swing-out distance adjustment process, the maintenance personnel face the following three deficiencies in the actual maintenance process: first, when using a steel tape measure to measure the swing-out distance of the door leaf, the operation personnel are above or below the door leaf, which is inconvenient for reading, and the reading error is large; in order to reduce the error, the steel tape measure needs to be measured multiple times and the average value is obtained, which is time-consuming; second, at least two people need to cooperate to complete the maintenance, and one maintenance personnel needs to fix the swing-out position of the door leaf, and another maintenance personnel needs to support and fix the door leaf during the adjustment of the position of the door leaf. At the same time, since it is a manual operation, the swing-out position of the door leaf cannot be stably maintained, and the distance will change slightly during the tightening of the bolt, causing the above steps to be repeated to adjust the swing arm data and state until the requirements are met; third, the correlation of the dimensions of the vehicle door is large, and the adjustment of a single dimension data may affect the overall size parameter; after loosening the two lower swing arm mounting seat nuts, the gap between the bottom surface of the vehicle door slide and the upper surface of the lower swing arm will also be affected; therefore, during the adjustment of the position of the door leaf swing arm, the swing-out size of the door leaf needs to be ensured not to change, and the gap size between the bottom surface of the vehicle door slide and the upper surface of the lower swing arm needs to be ensured within a reasonable range.

[0047] The locking reset unit is used to realize the locking and resetting functions; the locking reset unit comprises a second spring 441 and a locking piece 442, and the second spring 441 is a locking spring; the second spring 441 is sleeved outside the slide rail 100, one end of the second spring 441 is connected to the locking piece 442, and the other end of the second spring 441 is fixed to the mounting frame 410; the locking piece 442 is sleeved outside the slide rail 100, specifically, a through hole adapted to the slide rail 100 is formed in the locking piece 442, and the slide rail 100 passes through the through hole; an inner end of the locking piece 442 is fixedly connected to the mounting frame 410, and is configured to be obliquely pressed on the second spring 441 and provide a pre-pressing force for the second spring 441; the oblique direction is that an outer end of the locking piece 442 is obliquely upward;

[0048] The first support plate 210, the second support plate 220, the first spring 431, the sliding block 432, the second spring 441 and the locking piece 442 are sequentially arranged along the slide rail 100.

[0049] In some embodiments, the first support plate 210 is in an E shape, and the slide rail 100 is connected to the middle part of the side edge of the first support plate 210.

[0051] In the locking reset unit, the locking piece 442 is configured to be obliquely pressed on the second spring 441 to keep the second spring 441 in a pressed state; the locking piece 442 is inclined by the elastic force of the second spring 441, and the locking is realized by the friction force between the inner side of the through hole of the locking piece 442 and the slide rail 100.

[0052] In the present application, holding the movable handle 420, the sliding locking mechanism is in sliding state, which can drive the second support plate 220 to move along the slide rail 100; releasing the movable handle 420, the sliding locking mechanism remains in the locked state, and the sliding locking mechanism is fixed at a certain position on the slide rail 100; when the locking piece 442 is pressed, the locking is released.

[0053] The working principle of the sliding locking mechanism will be described in detail as follows:

[0054] In the reset state, the second support plate 220 is close to the first support plate 210; holding the movable handle 420, the first tongue 421 presses the outer end of the sliding block 432, the outer end of the sliding block 432 is pressed down, the sliding block 432 is compressed in an inclined state, the sliding block 432 is driven to slide by the friction force between the inner side of the through hole of the sliding block 432 and the slide rail 100, specifically, it slides away from the first support plate 210, and the second support plate 220 and the first support plate 210 are separated; when the movable handle 420 is released, the locking is achieved by the friction force between the inner side of the through hole of the locking piece 442 and the slide rail 100, at this time the sliding locking mechanism is fixed at a certain position on the slide rail 100; when the locking piece 442 is pressed, the inner side of the through hole of the locking piece 442 is parallel to the slide rail 100, the inner side of the through hole is no longer in contact with the slide rail 100, at this time the friction force between the inner side of the through hole and the slide rail 100 is eliminated, and the sliding locking mechanism slides until the second support plate 220 is close to the first support plate 210, returning to the reset state.

[0055] As a preferred solution, the above distance adjustment tool further comprises a fine adjustment mechanism 450, which comprises a mounting shell 451 sleeved outside the slide rail 100, a third spring 452 and a tongue mechanism; the mounting shell 451 is inclinedly pressed on the second spring 441 and provides a pre-pressure to the second spring 441, and the inner side of the bottom end of the mounting shell 451 is fixedly connected with the mounting frame 410 through a connecting piece; the locking piece 442 is installed at the bottom end of the mounting shell 451; the tongue mechanism comprises a connecting base 454 and a second tongue 453, the connecting base 454 is sleeved outside the slide rail 100 and located in the mounting shell 451, and is fixedly connected with the locking piece 442; the third spring 452 is installed in the mounting shell 451, and the two ends of the third spring 452 are connected with the mounting shell 451 and the connecting base 454 respectively; the second tongue 453 is located outside the mounting shell 451 and is rotationally connected with the connecting base 454, and the tongue mechanism is configured to: when the second tongue 453 is pressed, the connecting base 454 drives the inner side of the locking piece 442 to move towards the direction of compressing the third spring 452, that is, drives the inner side of the locking piece 442 to move upwards, thereby reducing the inclination of the locking piece 442.

[0056] The working principle of the above fine adjustment mechanism 450 is as follows: the second tongue 453 is pressed to gradually reduce the inclination of the locking piece 442, thereby reducing the locking force, and the sliding locking mechanism is slightly moved towards the first support plate 210 to achieve the fine adjustment purpose. When the inclination of the locking piece 442 is 0, the locking force disappears at this time.

[0057] When the distance between the second support plate 220 and the first support plate 210 exceeds the preset distance requirement during the distance adjustment of the electric sliding door leaf using the distance adjustment tool, the fine adjustment mechanism 450 can be used for readjustment, that is, the second tongue 453 is pressed to press the pressing locking piece 442, and the sliding locking mechanism is slightly moved towards the first support plate 210, thereby reducing the distance between the second support plate 220 and the first support plate 210.

[0058] The method for adjusting the distance between the upper and lower sides of the electric sliding door leaf using the above distance adjustment tool includes:

[0059] (1) The outer end surface of the first support plate 210 is attached to the inner side wall of the door leaf, the movable handle 420 is gripped, the sliding locking mechanism is slid along the slide rail 100 away from the first support plate 210, and the outer end surface of the second support plate 220 is attached to the door sill sealing surface; the distance between the first support plate 210 and the second support plate 220 is measured according to the scale on the slide rail 100, that is, the distance from the inner side wall of the door leaf to the door sill sealing surface; the distance plus the standard thickness of the door leaf 32 mm is the distance from the outer side wall of the door leaf to the door sill sealing surface;

[0060] (2) When the outer end surface of the first support plate 210 is attached to the inner side wall of the door leaf, the outer end surface of the second support plate 220 is attached to the door sill sealing surface, and the distance between the first support plate 210 and the second support plate 220 does not reach the preset distance requirement, the movable handle 420 is gripped, and the sliding locking mechanism is slid along the slide rail 100 away from the first support plate 210 to support the door leaf.

[0061] (3) When the outer end surface of the first support plate 210 is attached to the inner side wall of the door leaf, the outer end surface of the second support plate 220 is attached to the door sill sealing surface, and the distance between the first support plate 210 and the second support plate 220 exceeds the preset distance requirement, the second tongue 453 is pressed, and the sliding locking mechanism is slightly moved towards the first support plate 210 to shorten the distance between the first support plate 210 and the second support plate 220.

[0062] When the distance between the first support plate 210 and the second support plate 220 reaches the preset distance requirement, the movable handle 420 is released, and the first support plate 210 and the second support plate 220 support and fix the door leaf.

[0063] It should be noted that in the present application, the opposite faces of the first support plate 210 and the second support plate 220 are referred to as the inner end faces of the first support plate 210 and the second support plate 220, and the non-opposite faces of the first support plate 210 and the second support plate 220 are referred to as the outer end faces of the first support plate 210 and the second support plate 220.

[0064] In the above method, the distance between the first support plate 210 and the second support plate 220 is the distance from the inner side wall of the door leaf to the sealing surface of the door sill. Based on the door leaf swing-out distance adjustment process, the distance from the outer surface of the door leaf to the sealing surface of the door sill should satisfy 60-71 mm, and the distance between the first support plate 210 and the second support plate 220 plus the standard thickness of the door leaf 32 mm is the distance from the inner side wall of the door leaf to the sealing surface of the door sill. Therefore, the preset requirement that the distance from the inner side wall of the door leaf to the sealing surface of the door sill satisfies in the present application is that the distance from the inner side wall of the door leaf to the sealing surface of the door sill plus the standard thickness of the door leaf 32 mm should be 60-71 mm; that is, the distance between the first support plate 210 and the second support plate 220 plus the standard thickness of the door leaf 32 mm should be 60-71 mm.

[0065] Further, the present application provides a specific implementation process of the method of the present application, and the specific steps are as follows:

[0066] First, loosen the upper or lower swing arm mounting seat nut;

[0067] Second, place the distance adjustment tool flat, and press the outer end face of the first support plate 210 against the inner side wall of the door leaf, hold the movable handle 420 tightly, and slide the locking mechanism along the slide rail 100 in the direction away from the first support plate 210 until the outer end face of the second support plate 220 is pressed against the sealing surface of the door sill;

[0068] Third, loosen the movable handle 420, and measure the distance between the second support plate 220 and the first support plate 210. When the distance satisfies the preset distance requirement, execute the fourth step; otherwise, hold the movable handle 420 tightly, slide the locking mechanism along the slide rail 100 in the direction away from the first support plate 210, and support the door leaf until the distance between the second support plate 220 and the first support plate 210 satisfies the preset distance requirement, and then execute the fourth step;

[0069] Fourth, keep the movable handle 420 loosened, so that the sliding locking mechanism is in the locked state, and the first support plate 210 and the second support plate 220 play the role of supporting and fixing the door leaf. At this time, the maintainer adjusts the position of the upper or lower swing arm, and then pre-tightens the nut of the upper or lower swing arm mounting seat.

[0070] It should be noted that the position adjustment of the upper or lower swing arm by the maintainer includes moving the upper or lower swing arm up and down so that the gap between the bottom surface of the vehicle door lower slide and the upper surface of the lower swing arm or the gap between the top surface of the vehicle door upper slide and the lower surface of the upper swing arm satisfies the preset requirement.

[0071] The method can be used to adjust the up-and-down swing-out distance of the door leaf of the electric sliding plug door, and only one maintenance person is needed to complete the measurement and adjustment of the up-and-down swing-out distance, so that the manpower can be greatly saved, and the efficiency, precision and maintenance quality are improved.

[0072] To verify the technical effects produced by the method, the method is compared with the distance adjustment process mentioned in the background art (hereinafter referred to as “conventional method”). One group of people uses the conventional method to adjust the down-out swing size of a single door, and another group of people uses the method to adjust the down-out swing size of a single door. The adjustment target is 68 mm. Seven sets of test data are compared and listed in Table 1.

[0073] Table 1: Down-out swing size adjustment data of a single door leaf

[0074]

[0075] As shown in Table 1, when the conventional method is used to adjust the down-out swing size, the minimum error value is 1.5 mm, and the average error value is 1.78 mm. When the method is used to adjust the down-out swing size, the minimum error value is 0 mm, and the average error value is 0.27 mm. Obviously, the method greatly improves the accuracy of the down-out swing size adjustment.

[0076] To verify the working efficiency of the method, a vehicle carriage of a certain urban rail transit line is selected, which has 10 pairs of doors (i.e. 20 door leaves). The conventional method and the method are used to adjust the down-out swing distance of the door leaf of the door system of the 10 pairs of doors of the vehicle carriage, and the working time is counted and listed in Table 2.

[0077]

[0078] As shown in Table 2, the conventional method requires 2 maintenance personnel, and the average working time is 51 min / carriage. The method requires only 1 maintenance personnel, and the average working time is 25.6 min / carriage. The method can shorten the maintenance time by 74.9%, optimize the double-person operation to single-person operation, save 50% of the labor cost, and greatly improve the maintenance efficiency.

[0079] From January 2021 to January 2023, the electric passenger car door faults of a certain urban rail transit line were counted. There were 3 line faults and 5 in-warehouse self-maintenance faults caused by poor adjustment of the down-out swing distance of the door. After the door leaf swing gap is adjusted by the method, no similar faults occur on the line and in the warehouse from February 2023 to December 2024. Comparison shows that the method can effectively ensure the maintenance quality and reduce the line fault rate.

[0080] Although the embodiments of the present application have been shown and described above, it is understood that the above embodiments are exemplary, and are not to be interpreted as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
