Description

Technical Field

[0001] The utility model belongs to the technical field of subway door processing tooling equipment, and particularly relates to a fixing device for subway door installation and debugging. Background Art

[0002] The subway door is the door for passengers to enter and exit the subway car. It is generally designed to open and close automatically to provide safe and convenient passage at stations and during travel. Subway doors are usually equipped with safety sensors to prevent pinching people. To ensure that the door body aligns with the station platform when opening and closing, they are designed with durability and easy maintenance in mind to cope with high-frequency use and various climate conditions. Before installing the subway door, it needs to be debugged to ensure stability during formal use.

[0003] During the installation and debugging of subway doors, subway cars usually have plug-and-slide doors, which mainly include two actions: plugging and sliding. During the closing process, it is plugged into the doorway from inside and outside the car to close the door. When opening, after the door moves a certain distance, the plug-and-slide door can slide along the inner and outer sides of the car body. Therefore, during the installation and debugging of subway doors, the debugging structure used needs to be able to meet the installation and debugging requirements of the plug-and-slide door as described above. In the prior art, as disclosed in the utility model patent with the authorization announcement number CN213289989U, a fixing device for subway door assembly and debugging is disclosed. Through the setting of a subway door fixing frame composed of a fixing plate, a movable clamping plate, and a clamping electric push rod, the assembled subway door can be fixed and driven to move to achieve the purpose of simulating the opening and closing of the subway door, which is convenient for debugging the subway door. However, obviously, when the above-mentioned fixing device for subway door assembly and debugging is in use, there are still problems such as: 1. It cannot simulate that during the closing process of the plug-and-slide door, it is plugged into the doorway from inside and outside the car to close the door; when opening, after the door moves a certain distance, the plug-and-slide door can slide along the inner and outer sides of the car body. Therefore, it cannot effectively simulate the actual movement during the installation and debugging of the subway door; 2. At the same time, the bottom of the above-mentioned iron door fixing frame is in a cantilever shape, and the subway door is large in volume and heavy in weight. When positioning the subway door, it is easy for the subway door to slip off the bottom of the limit hook, resulting in poor fixing effect and increased debugging difficulty; and it cannot achieve the fixing of subway doors with different widths and specifications.

[0004] Based on this, the utility model proposes a fixing device for subway door installation and debugging to solve the problems existing in the above-mentioned prior art. Utility Model Content

Through the setting of the movable plate 3, the linkage adjustment between the positioning plate 4 and the driving mechanism 2 can be realized, so that the positioning plate 4 can move under the adjustment of the driving mechanism 2. Through the setting of the connecting frame 6 and the positioning mechanism 9, it is convenient to fix the subway door during use, and at the same time, it can be suitable for fixing subway doors with different thicknesses, solving the problems existing in the prior art that the subway door is prone to slipping off the bottom of the limiting hook, the fixing effect is poor and the debugging difficulty is increased.

[0055] As one of the preferred embodiments, as shown in Att. Figure 1 、Att. Figure 2 and Att. Figure 3 shown, the driving mechanism 2 includes a motor 201 and a driving lead screw 202; wherein:

The lower end of the vertical plate 301 is threadedly connected to the driving lead screw 202, and the horizontal plate 303 is used in cooperation with the movable groove 401 provided on the positioning plate 4.

[0060] It should be noted that in this embodiment, through the arrangement of the vertical plate 301 and the horizontal plate 303, when the driving lead screw 202 rotates, the moving plate 3 can be driven to move horizontally. Through the mutual clamping action between the clamping strip 302 and the guide rail groove 103, the stability of the moving plate 3 during horizontal movement can be effectively guaranteed, ensuring its adjustment effect. Through the clamping action between the horizontal plate 303 and the movable groove 401, the moving plate 3 is connected to the positioning plate 4, and during the adjustment process, the positioning plate 4 can move along the width direction of the horizontal plate 303 to drive the subway door to move.

[0061] As one of the preferred embodiments, as shown in the attached Figure 2 and the attached Figure 4 figure, two positioning columns 402 are further provided at the lower end of the positioning plate 4. The positioning columns 402 are used in cooperation with both the horizontal guide groove 101 and the inclined guide groove 102 opened on the fixed frame 1, and the horizontal guide groove 101 and the inclined guide groove 102 communicate with each other.

[0062] It should be noted that in this embodiment, through the cooperation of the positioning columns 402 with the horizontal guide groove 101 and the inclined guide groove 102, when in use, the positioning columns 402 are clamped in the horizontal guide groove 101 and the inclined guide groove 102. When the moving plate 3 moves, under the guiding action of the horizontal guide groove 101 and the inclined guide groove 102 on the positioning columns 402, the positioning plate 4 can move along the width direction of the horizontal plate 303 to drive the subway door to slide on the sliding groove, thereby realizing the function of testing the smoothness of the sliding of the subway door body.

[0063] As one of the preferred embodiments, as shown in the attached Figure 1 figure, the attached Figure 2 figure, the attached Figure 6 figure and the attached Figure 7 figure, the positioning mechanism 9 includes a fixed shell 901, a fixed block 902, a spring 905, and a bolt 909; wherein:

[0064] The fixed shell 901 is fixedly connected to one side of the connecting frame 6, and two limiting rods 903 are symmetrically inserted on one side of the fixed shell 901. One end of the limiting rod 903 movably penetrates the fixed shell 901, and the other end is fixedly connected to the fixing clamp plate 906. A limiting ring 904 is also fixedly connected to the end of the limiting rod 903 away from the clamp plate 906;

[0065] The fixing block 902 is fixedly connected to one side of the fixing shell 901 and is fixedly connected to one side of the connecting frame 6;

[0066] The spring 905 is fixedly connected to one side of the inner cavity of the fixed shell 901, and the other end of the spring 905 is fixedly connected to one side of the clamping plate 906;

[0067] The bolt 909 is threadedly connected between the fixing shell 901 and the clamping plate 906 .

[0068] It should be noted that in this embodiment, by setting the fixing shell 901, the fixing block 902, the spring 905, and the bolt 909, when in use, the clamping plate 906 can be moved to place the subway door between the clamping plate 906 on the top of the limiting plate 8 and the connecting frame 6, so as to prevent the subway door from falling off during the fixing process. At the same time, by loosening the clamping plate 906, and then driving the clamping plate 906 to rebound to one side of the subway door through the spring 905, the subway door is limited, and the subway doors of different thicknesses can be limited. Then, the clamping plate 906 is threadedly connected to the fixing shell 901 through the bolt 909, and then the subway door is clamped and fixed, thereby improving stability and reducing debugging difficulty, and can be applicable to the fixing of subway doors of different thicknesses, solving the problem that the subway door is prone to slipping through the bottom of the limiting hook, the fixing effect is poor, and the debugging difficulty is increased.

[0069] As one of the preferred embodiments, Figure 7 As shown, a protective pad 907 is fixedly connected to one side of the clamping plate 906, and the material of the protective pad 907 is rubber. Two limit blocks 908 are symmetrically fixedly connected to the bottom of the clamping plate 906, and the surface of the limit block 908 is slidably connected to the inner cavity slide groove 801 of the limit plate 8.

[0070] It should be noted that, in this embodiment, by providing the protective pad 907 and the limit block 908, the protective pad 907 is used to protect the subway door from damage on its surface; the limit block 908 cooperates with the slide groove 801 to guide the movement direction of the splint 906, thereby ensuring the uniformity of the splint 906 at various positions during movement.

[0071] As one of the preferred embodiments, Figure 1 , Attachment Figure 2 and attached Figure 7 As shown, a plurality of lightweight holes 7 are provided on the surface of the connecting frame 6 to reduce the overall weight of the connecting frame 6 when in use.

[0072] When the fixing device for subway door installation and debugging of the present utility model is in use, first, by turning the threaded rod 5, the length of the limiting plate 8 is adjusted. Then, the clamping plate 906 is toggled, and the subway door is placed on the top of the limiting plate 8 to prevent the subway door from falling off during the fixing process. By loosening the clamping plate 906, and then the clamping plate 906 is driven by the spring 905 to rebound to one side of the subway door to limit the subway door, so that the subway doors with different thicknesses can be limited. Then, the clamping plate 906 is threadedly connected to the fixed shell 901 through the bolt 909, thereby clamping and fixing the subway door. During the process of the clamping plate 906 clamping the subway door, the subway door is protected by the protective pad 907 to avoid damaging the surface of the subway door.

[0073] Subsequently, by rotating the motor 201 to drive the driving lead screw 202 to rotate, the moving plate 3 is driven to move along the length direction of the guide rail groove 103, and the subway door is driven to slide on the sliding groove, thereby realizing the function of testing the smoothness of the sliding of the subway door body.

[0074] It should be noted that in the above description, the motor 201, the driving lead screw 202, the threaded rod 5, the spring 905, the bolt 909, etc. are all devices with relatively mature applications in the prior art. The specific models can be selected according to actual needs. At the same time, the power supply of the motor 201 can be the built-in power supply or the mains power supply. The specific power supply method is selected according to the situation and will not be elaborated here.

[0075] The above is only the preferred embodiment of the present utility model and is not used to limit the protection scope of the present utility model.
