Description

Technical Field

[0001] The utility model relates to the technical field of train door detection, and more particularly to a device for measuring the gap size of a train door mechanism. Background Art

[0002] In the daily operation and maintenance of subway trains, the clearance dimensions of the door mechanisms play a crucial role, directly impacting train safety, passenger boarding and alighting convenience, and the interior comfort. Specifically, if the clearances between the various components of the door mechanism are too large, such as the tiny space between the door leaf and the door frame, or between the locking mechanism and the guide groove, they can cause the door to wobble during operation, allowing air and rain to leak in, and even affect its normal opening and closing functions, threatening passenger safety. Conversely, if the clearances are too small, the door may become obstructed during closing, increasing energy consumption and, over time, accelerating wear of the door components, reducing their service life.

[0003] However, the current measurement method is not efficient enough. Therefore, a low-cost method is needed to efficiently measure measuring plugs of various sizes to meet the measurement requirements of the gap size of subway train door mechanisms. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application. In the drawings, the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions. The described embodiments are part of the embodiments of this application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain this application, and should not be understood as limitations on this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] Figure 1 This is a schematic structural diagram of a train door mechanism gap size measuring device according to an embodiment of the present invention, wherein the train door mechanism gap size measuring device comprises:

[0031] A measuring assembly, comprising a minimum range measuring module 100 and a maximum range measuring module 200, wherein the minimum range measuring module 100 is provided with a minimum thickness, the maximum range measuring module 200 is provided with a maximum thickness, the minimum range measuring module 100 is provided with a minimum range measurement adjustment unit, and the maximum range measuring module 200 is provided with a maximum range measurement adjustment unit to adjust the minimum thickness and the maximum thickness;

[0032] An adjustment assembly 400 , wherein the thickness of the adjustment assembly 400 is within a range between a minimum thickness and a maximum thickness, and the adjustment assembly 400 is provided with a gap adjustment unit to properly adjust the vehicle door;

[0033] The minimum range measurement module 100 , the maximum range measurement module 200 and the adjustment component are integrally connected.

[0034] In one embodiment, the minimum range measurement adjustment unit is provided with a minimum thickness adjustment portion and a minimum length adjustment portion, the minimum thickness adjustment portion adjusts the minimum thickness, and the minimum length adjustment portion adjusts the length of the minimum range measurement module 100;

[0035] The maximum range measurement adjustment unit includes a maximum thickness adjustment portion and a maximum length adjustment portion. The maximum thickness adjustment portion adjusts the maximum thickness, and the maximum length adjustment portion adjusts the length of the maximum range measurement module 200 .

[0036] Specifically, the measuring component is made of wear-resistant material, and the thickness of the minimum range measuring module 100 is determined according to the minimum value of the gap regulation of the door mechanism gap size. Different minimum gap regulations have different door sizes. The minimum range measurement adjustment unit adjusts the minimum thickness by adjusting the thickness of the minimum range measuring module 100.

[0037] Furthermore, the thickness of the maximum range measurement module 200 is determined according to the maximum value of the gap regulation of the door mechanism gap size. Different maximum gap regulations have different door sizes. The maximum range measurement adjustment unit adjusts the maximum thickness by adjusting the thickness of the maximum range measurement module 200.

[0038] Furthermore, it is necessary to confirm the length of the minimum range measurement module 100 and the length of the maximum range measurement module 200 according to the insertable depth of the train door mechanism gap.

[0039] When the depth of the train door mechanism gap is small and the insertion depth of the measuring component in the train door mechanism gap size measuring device is small, it is necessary to perform minimum range length adjustment and maximum range length adjustment on the minimum range measuring module 100 and the maximum range measuring module 200 so that both the minimum range measuring module 100 and the maximum range measuring module 200 in the measuring component can be inserted into the door mechanism gap to detect whether the train door mechanism gap is between the minimum thickness and the maximum thickness.

[0040] In one embodiment, the minimum range measurement module 100 and the maximum range measurement module 200 are connected to form a straight-line measurement assembly with different thicknesses.

[0041] In one embodiment, in the inline-shaped measuring component, the minimum thickness is smaller than the maximum thickness.

[0042] Specifically, the inline measurement assembly consists of a minimum range measurement module 100 and a maximum range measurement module 200, with the minimum range measurement module 100 and the maximum range measurement module 200 located on the left and right sides of the inline measurement assembly, respectively. When the inline measurement assembly is inserted into the door mechanism gap, the minimum range measurement module 100 is first allowed to pass through the door mechanism gap. When the minimum range measurement module 100 passes through the door mechanism gap, it indicates that the door mechanism gap is greater than the minimum gap specified for the train door mechanism gap. Otherwise, the door mechanism gap is too small and does not comply with the regulations. After the minimum range measurement module 100 completely passes through the train gap, the maximum range measurement module 200 begins to prepare to enter the door mechanism gap. When the maximum range measurement module 200 cannot pass through the train door mechanism gap, it indicates that the door mechanism gap at this time complies with the train door mechanism gap regulations. Otherwise, it indicates that the door mechanism gap is too large and does not comply with the regulations.

[0043] In one embodiment, a support portion 300 is provided between the straight-line measuring assembly and the adjusting assembly.

[0044] In one embodiment, the maximum range measurement module 200 of the inline measurement assembly is connected to the support portion 300 .

[0045] In one embodiment, the adjustment component 400 is a straight-line adjustment component 400 , and the thickness of the straight-line adjustment component 400 ranges between a minimum thickness and a maximum thickness.

[0046] If the measuring assembly measures the door clearance and finds it too small or too large, it needs to be readjusted. This requires simply inserting the adjustment assembly 400 into the door clearance, using the thickness of the adjustment assembly 400 as a reference for adjustment, to achieve precise adjustment of the door clearance.

[0047] In one embodiment, the inline measuring assembly, the supporting portion 300 and the inline adjusting assembly 400 form a Z shape.

[0048] Specifically, the measuring component and the adjusting component 400 are designed as one body and in a Z-shape so as not to interfere with the realization of their respective functions, which is simple and convenient.

[0049] In one embodiment, the minimum range measurement module 100 , the maximum range measurement module 200 , and the adjustment assembly 400 are made of wear-resistant metal materials.

[0050] In one embodiment, the minimum range measurement module 100 , the maximum range measurement module 200 , and the adjustment assembly 400 are made of wear-resistant non-metallic materials.

[0051] Specifically, since the measuring assembly and the adjusting assembly 400 need to be inserted into the gap between trains, a lot of friction will be generated when moving back and forth, and therefore both the measuring assembly and the adjusting assembly 400 need to have wear-resistant properties.

[0052] Specifically, when using the train door mechanism gap measurement device of this application, the operator inserts the corresponding measuring block into the door mechanism gap. By observing the insertion depth and tightness of the device, the operator can quickly determine whether the door mechanism gap size is within the allowable range. If the gap size does not meet the requirements, the operator can use the intermediate size measuring block to make detailed adjustments to achieve the ideal intermediate value.

[0053] In one embodiment, the S1 limit switch gap is measured, such as Figure 4 As shown, first insert the measuring assembly of the train door mechanism gap size measuring device between the axial ends of the S1 switch contact rod roller. Observe whether the insertable part is the minimum range measuring module 100 or the maximum range measuring module 200 to determine whether the size of the S1 switch is normal.

[0054] If the measured gap size does not meet the standard requirements, it is necessary to adjust the gap. Insert the adjustment component 400 between the axial ends of the S1 switch contact rod rollers and use this as a reference size to achieve precise gap adjustment.

[0055] In one embodiment, the clearance between the auxiliary door support wheels is measured, such as Figure 5 As shown, first insert the measuring component of the train door mechanism gap size measuring device into the gap between the door leaf and the auxiliary support wheel, and observe whether the inserted part is the minimum range measuring module 100 or the maximum range measuring module 200 to determine whether the auxiliary support wheel is of normal size.

[0056] If the measured gap size does not meet the standard requirements, it is necessary to adjust the gap. Insert the adjustment component 400 into the gap between the door leaf and the auxiliary support wheel, and use this as a reference size to achieve precise gap adjustment.

[0057] In one embodiment, the door leaf height gap is measured. When the door is closed, the measuring component of the train door mechanism gap size measuring device is inserted into the gap between the door leaf and the door sill. At this time, it is observed whether the inserted part is the minimum range measurement module 100 or the maximum range measurement module 200 to determine whether the door height size is normal.

[0058] If the measured gap size does not meet the standard requirements, it is necessary to adjust the gap. Insert the adjustment component 400 into the gap between the door leaf and the threshold, and use this as a reference size to achieve precise gap adjustment.

[0059] The utility model has the following beneficial effects:

[0060] High flexibility: The thickness and length can be adjusted to provide measurement and adjustment of the clearance of door mechanisms of various sizes.

[0061] High efficiency: This device can not only be used to measure the size of the door mechanism gap, but also can adjust the door mechanism gap by adjusting the components. When the measurement result shows that the size is unqualified, the door mechanism gap can be directly adjusted, further improving the efficiency of measurement and adjustment.

[0062] Simple structure: The measuring component and the adjusting component are designed as one body in a Z-shape, which does not interfere with the realization of their respective functions. The structure is simple and the operation is convenient.
