Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary device for a height measuring tape measure, in particular to an auxiliary device for a train height measuring tape measure. Background Art
[0002] When electric train wheels undergo wear and tear, after wheelset turning, or during routine maintenance, the distance between the floor of each train section and the upper surface of the rails must be measured to ensure the entire train floor is between 1120mm and 1140mm. If this dimension is too large or too small, a step or difference between the platform floor and the passenger compartment floor will form after the train stops. Therefore, this dimension ensures the safety and comfort of passengers boarding and alighting.
[0003] During floor height measurement, routine inspection procedures dictate that the train compartment floor threshold be used as the upper measurement point; a standard aluminum hollow square tube be used as a horizontal bar, resting on the upper surface of the rails as the lower measurement point. A steel tape measure is used for measurement, with its hook attached to the upper outer edge of the train compartment floor threshold. While holding the tape hook with one hand, pull it down with the other, measuring to the lower edge of the standard aluminum hollow square tube. This process presents the following issues:
[0004] 1) If the floor height is not within the standard range, adjust the height valve connecting rod's vertical displacement after each measurement to change its opening, thereby varying the amount of air flowing into the air spring to raise or lower the floor. Measure again. During this adjustment process, there is no consistent linear relationship between the floor height and the height valve's adjustment range. For continuous adjustment, two maintenance personnel are required: one person holding a tape measure to check the height while the other adjusts the height valve opening.
[0005] 2) During the floor height measurement process, the tape measure hook is hooked on the outer edge of the threshold, which is about two meters away from the ground. The maintenance personnel need to hold the tape measure hook with one hand while looking sideways at the lower tape measure scale to read the reading. Because the maintenance personnel are not looking straight at the tape measure body, it is easy to cause visual errors when reading, resulting in measurement deviation.
[0006] 3) Since the hook of the tape measure is designed with a top-rule or pull-rule measurement method, it is used to compensate for the thickness of the hook during measurement. Therefore, when designing the tape measure, the design manufacturer will design the tape measure hook to be movable to ensure measurement accuracy. The movable tape measure hook will cause instability when hanging. The hook is rectangular with rounded corners and the longitudinal length of the tape measure hook is only 6-8mm when fully hung. It is easy to cause the tape measure to fall, resulting in damage to the tape measure during the measurement process.
[0007] 4) Since the distance from the upper surface of the rail to the upper surface of the floor is required to be 1120mm-1140mm in the inflated state, and since the height of the ground where the maintenance personnel stand and the upper surface of the rail are different in each maintenance base, the distance of some maintenance bases can reach 1300mm when it is too large. The sum of the two dimensions is 2420-2440mm. If the hanging height is too high, some maintenance personnel will tiptoe to hang the tape measure, which brings inconvenience to the maintenance work.
[0008] In summary, this current measurement method is still inconvenient for on-site work and may even cause measurement errors or damage to tools. Utility Model Content

[0043] Figure 1 and Figure 3 The auxiliary device structure of the train height measuring tape according to the preferred embodiment of the present invention comprises a positioning module 1 and a horizontal reference module 2.
[0044] like Figure 2 As shown, the positioning module 1 includes: an anti-fall bracket 11, which includes a horizontal part and a vertical part, and the anti-fall bracket 11 is in contact with the floor threshold 3 of the subway train; a counterweight component 12, which is installed on the horizontal part of the anti-fall bracket 11; and an anti-fall magnetic component 13, which is installed on the anti-fall bracket 11.
[0045] The horizontal part and the vertical part of the anti-fall bracket 11 are both provided with holes.
[0046] There are two uneven planes on the horizontal part of the anti-fall bracket 11, of which the higher plane of the horizontal part of the anti-fall bracket 11 is used to install the counterweight component 12. The counterweight component 12 includes an upper counterweight block 121 and a lower counterweight block 122. The counterweight component 12 has holes corresponding to the anti-fall bracket 11 and is installed on the horizontal part of the anti-fall bracket 11 through fasteners. The upper counterweight block 121 is installed on the upper part of the higher plane of the horizontal part of the anti-fall bracket 11, and the lower counterweight block 122 is installed on the lower part of the higher plane of the horizontal part of the anti-fall bracket 11. The counterweight component 12 ensures that the downward pressure on the contact surface of the door sill 3 is increased without changing the measurement position and measurement accuracy, so that the positioning module 1 and the tape measure are tightly attached to the outer door sill.
[0047] The anti-falling magnetic component 13 includes an upper magnetic component 131 and a lower magnetic component 132. The upper magnetic component 131 is installed on the lower plane of the horizontal part of the anti-falling bracket 11. The vertical part of the anti-falling bracket 11 has two planes of different heights. The lower magnetic component 132 is installed on the lower plane of the vertical part of the anti-falling bracket 11.
[0048] The anti-falling magnetic component 13 has a hole position corresponding to the anti-falling bracket 11 , and the anti-falling magnetic component 13 is mounted on the anti-falling bracket 11 through a fastener.
[0049] When measuring, the tape measure hook is adsorbed on the upper magnetic component 131, which increases the force area when the tape measure is hung and improves the stability during measurement; the lower magnetic component 132 is used to adsorb the tape measure body to prevent the tape measure from shaking, so that the tape measure is perpendicular to the ground during measurement, ensuring accurate data.
[0050] The horizontal reference module 2 includes: a horizontal rod 21, which is in contact with the upper plane of the rail on which the subway train is located; a fixed magnetic component 22, which is installed on the bottom surface of the horizontal rod; and a reference component 23, which is installed at the front end of the horizontal rod 21.
[0051] The horizontal rod 21 is a rectangular aluminum tube with holes on both its top and bottom surfaces, and a partition extending from the bottom. The horizontal rod serves as the lower measurement reference surface. It is attached to the rail's upper surface via a fixed magnetic component 22, ensuring a secure fit and preventing side-to-side displacement during measurement. A horizontal tube is installed at the front end of this tool to ensure the accuracy of the reference surface during measurement.
[0052] The fixed magnetic component 22 has holes corresponding to the horizontal rod 21 , and the fixed magnetic component 22 is mounted on the bottom surface of the horizontal rod 21 through fasteners.
[0053] The reference component 23 has holes corresponding to the horizontal rod 21 , and the reference component 23 is installed at the front end of the horizontal rod 21 through fasteners.
[0054] The reference component 23 is a horizontal tube.
[0055] The auxiliary device of the train height measuring tape also includes a tape fixing device, which is installed on the horizontal rod. The tape fixing device includes a rotatable clamp, and an elastic clip is arranged inside the clamp.
[0056] The specific operating steps of the auxiliary device for a train height measuring tape in the preferred embodiment of the utility model are as follows:
[0057] Before operation, confirm the train door type and door sill installation type. If the floor sill is exposed, it can be directly inspected and measured. If the floor sill is on the inside of the door leaf (such as a Sierra door), all train doors must be opened before the floor height measurement can be carried out.
[0058] When measuring, first adsorb the horizontal reference module 2 of the auxiliary device of the train height measuring tape on the rail, confirm that the bubble of the level tube at the front end of the horizontal rod 21 is between the two scale lines, adsorb the tape hook on the upper magnetic component 131 of the positioning module 1 of the auxiliary device of the train height measuring tape, stretch the tape, adsorb the tape body on the lower magnetic component 132 of the positioning module 1 of the auxiliary device of the train height measuring tape, pick up the device and hang it directly on the outer door sill 3 of the train floor surface, as shown in the figure. Figure 4 As shown, the two planes of the positioning module are closely attached to the upper contact surface 4 and the side contact surface 5 of the outer door sill to ensure the accuracy of the measurement. Then, the data of the tape measure at the lowest point of the horizontal reference module 2 is read from a horizontal angle, which is the floor height dimension data, and then recorded to complete the measurement.
[0059] The utility model has the following beneficial effects:
[0060] 1. The utility model is an auxiliary device for a train height measuring tape, which is easy to take and use. Only one staff member is needed to measure the train height, thereby improving the work efficiency of maintenance personnel.
