Description

Technical Field

[0001] The present invention relates to the technical field of subway screen door assembly, and more specifically, to a subway screen door assembly device and method. Background Art

[0002] The subway screen door is a safety facility installed on the edge of the subway platform. It is usually composed of a transparent glass door and is located between the train and the platform. It is used to isolate the platform from the track. Its main function is to ensure the safety of passengers. The main purpose of setting up the screen door is to prevent people from falling onto the track and causing accidents, reduce the operating energy consumption of the station's air-conditioning and ventilation system, and reduce the impact of train running noise and piston wind on the station. It provides passengers with a safe and comfortable waiting environment, avoids delays in operations due to platform accidents, and improves the service level of rail transit.

[0003] When assembling the current subway screen door, two sliding door thresholds need to be positioned and installed at the platform, and there is a certain gap between the two sliding door thresholds, and the gap is used as the slide rail of the subway screen door, and then the guide shoe plate at the bottom of the subway screen door is extended into the slide rail. If the gap is too small, friction will occur when the guide shoe plate slides in the slide rail, resulting in increased wear and affecting the smooth operation of the screen door. At the same time, if the gap is too large, the screen door will shake during operation, affecting the stability and safety of the screen door when sliding. The gap between the two sliding door thresholds should be slightly larger than the width of the guide shoe plate, but not too large. Therefore, it is necessary to ensure the precise positioning and installation of the two sliding door thresholds.

[0004] In the prior art, the sliding door threshold is positioned by using a measuring tool, and the position is manually marked on the platform floor before the sliding door threshold is installed. However, if the position is positioned by manual marking and then installed, it is easy to cause deviations during the installation and assembly process, affecting the assembly and positioning accuracy of the sliding door threshold. Therefore, in the prior art, when assembling and positioning the sliding door threshold, a stop block can be set between the two sliding door thresholds so that the two sliding door thresholds are abutted against the stop block, thereby achieving the effect of accurately positioning, assembling and installing the sliding door threshold.

[0005] However, by abutting the two sliding door sills with the abutting block, after the sliding door sills are positioned, assembled and installed, it is difficult to remove the abutting block because the abutting block and the sliding door sills are in an abutting state during assembly and installation. Removing the abutting block will also cause wear on the edge positions of the two sliding door sills and damage the anti-rust layer on the edge of the sliding door sills. Therefore, the prior art can adopt two abutting plates with adjustable spacing between the two sliding door sills, so that the two abutting plates are abutted and positioned with the corresponding sliding door sills, and after the sliding door sills are installed, the distance between the two abutting plates can be shortened and the abutting plates can be taken out, so that the abutting plates are easy to take out and will not cause damage to the edge of the sliding door sill when taken out.

[0006] However, the gap between the two sliding door thresholds is the sliding rail, and its width is relatively small. If two abutment plates with adjustable spacing are set, the abutment plates need to be thinner. In addition, in order to ensure accurate positioning of the sliding door threshold over the entire length, the abutment plates need to be set to be close in length to the sliding door threshold, so that the abutment plates need to be set to be thinner and longer. In this case, when the sliding door threshold is supported, abutted and limited by the abutment plates, the abutment plates are easily deformed due to the pressure applied during installation when the sliding door threshold is installed. If the abutment plates are deformed, the assembly accuracy of the sliding door threshold will be affected. Summary of the invention

[0007] The present invention provides a subway screen door assembly device and method, and aims to solve the following problem: the gap between the two existing sliding door thresholds is a slide rail, and its width is relatively small. If two abutment plates with adjustable spacing are provided, the abutment plates need to be relatively thin. In addition, in order to ensure accurate positioning of the sliding door threshold over the entire length, the abutment plates need to be provided with a length close to that of the sliding door threshold, so that the abutment plates need to be provided to be relatively thin and relatively long. Then, when the sliding door threshold is supported, abutted and limited by the abutment plates, the abutment plates are easily deformed due to the pressure applied during installation when the sliding door threshold is installed. If the abutment plates are deformed, the assembly accuracy of the sliding door threshold will be affected.

DETAILED DESCRIPTION

[0044] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0045] Refer to the instruction manual Figures 1 to 5 A subway screen door assembly device comprises: a body 1, a clamping mechanism 2 capable of linear motion is arranged on the body 1, the clamping mechanism 2 comprises two clamping seats 24 capable of synchronously moving in opposite directions, two sliding door thresholds 10 are located between the two clamping seats 24, and the two clamping seats 24 are used to limit the sides of the two sliding door thresholds 10 that are away from each other;

[0046] The clamping mechanism 2 is provided with a positioning mechanism 3, which includes two abutment plates 31 that can move synchronously in opposite directions. The two abutment plates 31 are located between the sliding door thresholds 10, and the two abutment plates 31 and the two clamping seats 24 move in the same horizontal direction.

[0047] A pushing member 36 is provided between the two abutment plates 31 for vertical sliding. The pushing member 36 is used to push the two abutment plates 31 to move in different directions so that the two abutment plates 31 abut against the corresponding sliding door thresholds 10. When the two abutment plates 31 abut against the corresponding sliding door thresholds 10, the pushing member 36 fills the space between the two abutment plates 31.

[0048] It should be noted that in the initial state, the two abutment plates 31 are attached together, and there is no gap between the two abutment plates 31. The gap area between the two abutment plates 31 is the gap area between the two abutment plates 31 after the two abutment plates 31 are driven to move in different directions.

[0049] The specific implementation scenario is as follows: first, two sliding door thresholds 10 to be assembled are placed on the subway platform, and then the clamping mechanism 2 is driven to move horizontally and linearly, so that the clamping mechanism 2 moves to the top of the two sliding door thresholds 10, and then the clamping mechanism 2 is driven to move vertically and linearly, so that the clamping mechanism 2 moves downward, and the two clamping seats 24 are respectively in contact with the side away from the two sliding door thresholds 10, and the two abutment plates 31 are extended to the gap between the two sliding door thresholds 10, and the gap is the distance between the two sliding door thresholds 10 to form the slide rail, and then the positioning mechanism 3 drives the pusher The pusher 36 moves linearly downward and pushes the two abutment plates 31 to move away from each other, so that the two abutment plates 31 are fitted and abutted against the corresponding sliding door sills 10, and the pusher 36 fills the spacing area between the two abutment plates 31, so that the two sliding door sills 10 can be accurately positioned by the two abutment plates 31 and the two clamp seats 24, and the pushing member 36 fills the spacing area, which increases the supporting strength of the two abutment plates 31, thereby reducing the possibility of deformation of the abutment plates 31 due to external force during the installation of the sliding door sill 10, and improving the assembly accuracy of the sliding door sill 10.

[0050] For further information, please refer to the attached manual. Figures 2 to 5 The positioning mechanism 3 also includes two sliding seats 32, the two abutment plates 31 are respectively fixed at the bottom of the corresponding sliding seats 32, and the two sliding seats 32 are each provided with an elastic member 33 on the side away from each other, and the elastic member 33 is used for the reset movement of the two abutment plates 31. The positioning mechanism 3 also includes a power component 34, and the output end of the power component 34 is provided with a connecting frame 35, and a pushing member 36 is fixedly arranged at the bottom of the connecting frame 35, and the pushing member 36 is set in a trapezoidal shape. The sides of the two abutment plates 31 that are close to each other are both inclined, and the two sides of the pushing member 36 are in sliding contact with the corresponding inclined surfaces.

[0051] It should be noted that the elastic member 33 is a spring, and the pushing member 36 is a trapezoidal plate arranged in a trapezoidal shape. Through the sliding contact between the trapezoidal plate and the inclined surfaces of the two abutment plates 31, the trapezoidal plate can push the two abutment plates 31 to move away from each other during the downward movement until the two abutment plates 31 contact and abut with the corresponding sliding door thresholds 10, and when the two abutment plates 31 contact and abut with the corresponding sliding door thresholds 10, the trapezoidal plate can fill the space between the two abutment plates 31, thereby increasing the supporting strength of the two abutment plates 31 and reducing the possibility of deformation of the abutment plates 31 due to external force during the installation of the sliding door threshold 10.

[0052] In the above technical solution, the pushing member 36 fills the space between the two abutment plates 31 to increase the supporting strength of the two abutment plates 31, thereby reducing the possibility of deformation of the abutment plates 31 due to external force during the installation of the sliding door threshold 10. However, when the two abutment plates 31 extend to the gap between the two sliding door thresholds 10, there is still a gap between the abutment plates 31 and the sliding door threshold 10. In addition, during the construction process in the subway station, there will be multiple construction projects at the same time. Therefore, debris generated by other construction projects will splash into the gap. If the debris splashes into the gap, the abutment plates 31 will not be able to fully fit and press against the sliding door threshold 10 due to the presence of the debris in the gap, thereby affecting the installation and assembly accuracy of the sliding door threshold 10. For this reason, the present invention proposes a blowing mechanism 4 for solving the above problem.

[0053] For details, please refer to the attached manual. Figure 6 and Figure 7 A blowing mechanism 4 is provided on the support plate 31, and the blowing mechanism 4 includes an air supply component 41. The air supply component 41 is used to supply gas to the gap between the support plate 31 and the sliding door threshold 10 to prevent debris from entering the gap. The blowing mechanism 4 also includes an inner cavity 43. The inner cavity 43 is opened in the support plate 31. The air outlet end of the air supply component 41 is connected to an air supply pipe 42. The air outlet end of the air supply pipe 42 is connected to the inner cavity 43. A plurality of air outlet holes 44 are opened on the support plate 31. The plurality of air outlet holes 44 are all connected to the inner cavity 43. The air supply component 41 supplies air to the inner cavity 43 through the air supply pipe 42, and blows air to the gap between the support plate 31 and the sliding door threshold 10 through the plurality of air outlet holes 44.

[0054] It should be noted that the gap is the distance between the back plate 31 and the sliding door sill 10 when the back plate 31 extends to the gap between the two sliding door sills 10. The air supply component 41 is an air pump, which delivers air to the inner cavity 43 through the air pump and the air supply pipe 42, and discharges the air through a plurality of air outlet holes 44, so that the air from the air outlet holes 44 is blown to the opening of the gap, and debris is blocked to prevent the debris from entering the gap.

[0055] In the above technical solution, air is blown by the blowing mechanism 4 to prevent debris from entering the gap. However, when the push plate 31 is driven to extend to the gap, before the push plate 31 enters the gap, the debris is likely to directly enter the gap, causing the push plate 31 to remain in the gap. If the debris is large, it can be taken out before the push plate 31 enters the gap. If the debris is slightly smaller, the operator is likely to ignore the smaller debris, causing the bottom of the push plate 31 to abut against the debris when the push plate 31 enters the gap. When the two push plates 31 are driven to move away from each other, since the push member 36 is required to fill the spacing area, the presence of the debris will make it difficult for the push member 36 to fill the spacing area. If the push member 36 cannot fill the spacing area, the two push plates 31 will not be able to fit and abut against the corresponding sliding door sills 10, which will affect the assembly accuracy of the sliding door sill when the sliding door sill 10 is installed. For this reason, the present invention proposes a chip blowing mechanism 5 for solving the above problems.

[0056] For details, please refer to the attached manual. Figures 8 to 10 A chip blowing mechanism 5 is provided on the abutment plate 31, and the chip blowing mechanism 5 includes a side tube 51, and the air inlet end of the side tube 51 is connected to the air supply pipe 42. An inner cavity 52 is also provided in the abutment plate 31, and the air outlet end of the side tube 51 is connected to the inner cavity 52. ​​A plurality of second air outlet holes 53 are provided at the bottom of the abutment plate 31, and the plurality of second air outlet holes 53 are all connected to the inner cavity 52. ​​A notch 54 is provided on one side of the bottom of the abutment plate 31, and the chip blowing mechanism 5 blows air to the bottom of the gap between the two sliding door thresholds 10 through the plurality of second air outlet holes 53 to blow the debris to the notch 54.

[0057] It should be noted that by adopting the side pipe 51 to connect with the air supply pipe 42, when the air pump delivers air through the air supply pipe 42, a part of the air flow is separated and delivered from the side pipe 51 to the inner cavity 52, and the separated air flow is blown toward the bottom of the gap from the plurality of air outlet holes 53, so that when the stop plate 31 moves into the gap, the air flow is blown toward the bottom of the gap, and the debris entering the gap is blown to both sides of the gap, and the debris is located in the notch 54, so that the debris does not affect the installation and assembly accuracy of the sliding door threshold 10.

[0058] It should also be noted that by directly opening a notch 54 on the side of the abutment plate 31, the problem of debris splashing into the gap after the abutment plate 31 enters the gap can be solved. The debris can enter the notch 54 from the gap to solve the problem of debris affecting the assembly accuracy. However, there is still a problem that the debris is stuck in the gap and cannot enter the notch 54. Therefore, it is necessary to use the blowing mechanism 4 to solve the problem of debris splashing into the gap.

[0059] In the above technical solution, the debris entering the gap is blown to both sides of the gap by blowing toward the bottom of the gap through the chip blowing mechanism 5. If the air blows the debris to the side of the gap higher than the position of the notch 54, the debris will still be stuck in the gap. For this reason, the present invention proposes a chip suction mechanism 6 to solve the above problem.

[0060] For details, please refer to the attached manual. Figures 11 to 13 A debris suction mechanism 6 is also provided on the abutment plate 31, and the debris suction mechanism 6 includes an exhaust component 61, and the exhaust end of the exhaust component 61 is connected to an exhaust pipe 62, and the exhaust end of the exhaust pipe 62 is connected to the inner cavity 52, and a plurality of air inlet holes 63 are opened on the inner wall of the notch 54. The exhaust component 61 exhausts air through the plurality of air inlet holes 63 to absorb debris in the notch 54.

[0061] It should be noted that the exhaust component 61 is an exhaust pump, which extracts air through the exhaust pump and the air inlet 63, so that when the air is extracted, the debris is sucked into the notch 54, thereby solving the problem of the debris blown into the gap affecting the installation and assembly accuracy of the sliding door threshold 10.

[0063] It should be noted that the driving member 22 is a motor, and the screw rod 23 is a bidirectional screw rod. The motor drives the bidirectional screw rod to rotate, so that it is connected to the bidirectional screw rod thread through the clamp seat 24, thereby driving the two clamp seats 24 to move synchronously in opposite directions, so that the two sliding door thresholds 10 can be limited by adjusting the distance between the two clamp seats 24.

[0064] For further information, please refer to the attached manual. Fig.14 A linear drive mechanism 7 is provided at the bottom of the body 1, and the linear drive mechanism 7 is used to drive the clamping mechanism 2 to move horizontally and linearly.

[0066] For further information, please refer to the attached manual. Fig.15 A linear drive mechanism 28 is provided on the support seat 73. The linear drive mechanism 28 is used to drive the clamping mechanism 2 to move vertically linearly. The linear drive mechanism 28 includes a support 81. The support 81 is installed on the support seat 73. A driving member 3 82 is installed on the support 81. The output end of the driving member 3 82 is connected to a screw rod 3 83.

[0067] It should be noted that the driving member 3 82 is a motor, which drives the screw rod 3 83 to rotate, so that it is connected with the thread of the screw rod 3 83 through the sliding seat 84, so that it can drive the sliding seat 84 to move vertically linearly, and then drive the clamping mechanism 2 to move vertically linearly.

[0068] Refer to the instruction manual Fig.16 , a method for assembling a subway screen door assembly device, comprising the following steps:

[0069] Step 1: Place two sliding door thresholds 10 to be assembled on the subway platform, drive the clamping mechanism 2 to move to the top of the two sliding door thresholds 10 through the linear drive mechanism 1 7, and drive the clamping mechanism 2 to move downward through the linear drive mechanism 2 8, so that the sides of the two sliding door thresholds 10 are in close contact with the corresponding clamping seats 24;

[0070] Step 2: When the clamping mechanism 2 moves downward, the chip blowing mechanism 5 blows air toward the bottom of the gap to blow the chips in the gap to the notch 54 of the abutment plate 31;

[0071] Step 3: When the abutment plate 31 contacts the bottom of the gap, the chip blowing mechanism 5 stops blowing, and the chip suction mechanism 6 sucks air to absorb the debris, while the blowing mechanism 4 delivers gas to the gap between the abutment plate 31 and the sliding door threshold 10;
