Description

Technical Field

[0001] The present application relates to the field of escalators, and in particular to an escalator measuring device based on a displacement sensor. Background Art

[0002] Escalators are common facilities in modern life, and escalators are generally placed at an angle. When pedestrians stand on the automatic steps at one end of the escalator, they will be automatically taken to the other end of the escalator, and the steps will remain horizontal all the way. Escalators are generally installed in public places, such as shopping malls, so they are used for a long time and have a large load capacity. Therefore, regular maintenance is very important for the safe operation of escalators. The safe operation of escalators includes many items, such as the gap between the steps and the apron board. When the gap between the steps and the apron board is too large, the trouser legs or skirts of pedestrians may be involved in the gap between the steps and the apron board, causing safety hazards. Therefore, it is necessary to regularly measure the gap between the steps and the apron board, but the height span of the escalator is generally large. In the past, measurements were generally made using a special measuring ruler, but this measurement method relies on manual readings, which is prone to errors, and can only measure one point each time, and cannot measure the gap of the entire apron board. Therefore, the measured data is not comprehensive enough, and manual measurement is not conducive to the subsequent entry and processing of measurement data. Summary of the invention

[0003] Purpose of the invention: This application aims to overcome the defects of the prior art and provide an escalator measuring device based on a displacement sensor.

[0004] Technical solution: An escalator measuring device based on a displacement sensor, comprising a mounting seat and a displacement sensor mounted on the mounting seat, the mounting seat comprising a fixing seat and a socket, the fixing seat comprising a horizontal plate, two side plates fixedly connected to the horizontal plate, a plurality of support units fixedly connected to the horizontal plate and located between the two side plates, and two fixing plates fixedly connected to the horizontal plate and located above the horizontal plate, each support unit comprising two support plates, both ends of the fixing plate having limiting slide grooves, a clamping unit being mounted on each fixing plate, the clamping unit comprising a clamping plate and a slide rail fixedly connected to the clamping plate and cooperating with the limiting slide groove, the fixing plate It has a threaded hole, and a clamping bolt with an end abutting the clamping plate is installed at the threaded hole, and the displacement sensor is clamped between the two clamping plates; the side plate has an insertion channel, and the socket includes a base plate, a plug rod connected to the base plate, and a plurality of plug plates, a connecting plate is connected between each plug plate and the base plate, and the plug plate includes a guide plate and a clamping plate connecting the guide plate and the connecting plate, the plug rod can be inserted into the insertion channel and the end of the plug rod has an external thread, and a locking nut is installed at the external thread, the number of the plug plates is equal to the number of the support units and the two correspond one to one, and each plug plate is inserted between the two support plates of a support unit.

[0005] Furthermore, the displacement sensor is integrated with a control unit and a wireless communication unit.

[0006] Furthermore, two sides of the abutting plate abut against two supporting plates corresponding to the abutting plate; and two sides of the guide plate have guiding arc surfaces.

[0007] Therefore, by virtue of the narrower feature of the end portion of the guide plate, the abutting plate can be smoothly inserted into the corresponding supporting unit.

[0008] Furthermore, each side plate is provided with two insertion channels, and the base plate is provided with four insertion rods.

[0009] Therefore, the installation of the fixing seat and the socket can be achieved by locking the four plug rods and the four locking nuts.

[0010] Furthermore, the locking nut is provided with two rotating knobs.

[0011] The lock nut can thus be tightened without tools.

[0012] Furthermore, the clamping plate has a plurality of transverse reinforcing ribs and a plurality of vertical reinforcing ribs.

[0013] Thereby increasing the rigidity of the clamping plate, thereby achieving better clamping of the displacement sensor.

[0014] Furthermore, the number of the support units is greater than or equal to 5, and all the support units are distributed in a row with equal intervals.

[0015] The installation is more stable by installing multiple support units on the convex ribs of the steps.

[0016] Furthermore, two tightening bolts are installed at each fixing plate.

[0017] More tightening bolts can be provided as needed to tighten the displacement sensor.

[0018] Furthermore, the clamping plate has an anti-slip pad that abuts against the displacement sensor.

[0019] Furthermore, arc-shaped grooves are provided on both sides of the top end of the support plate.

[0020] This makes it easier for the support plate to achieve slight left-right deformation relative to the horizontal plate, so that the support plate can better press against the convex ribs at the steps, thereby achieving better installation of the mounting seat.

[0021] Furthermore, the inner sides of the two support plates of the support unit are provided with horizontal support bars, and the plug plate is located above the two horizontal support bars of the corresponding support unit and abuts against the two horizontal support bars.

[0022] Therefore, the horizontal support bar can provide vertical support for the plug board, making the socket and the fixing seat more stable.

[0023] Beneficial effect: The measuring device of the present application realizes stable installation of the displacement sensor by setting a mounting base, so that as the step moves upward, the gap between the step and the apron plate can be measured in the entire apron plate area, and automatic measurement can be realized, which facilitates data recording and subsequent processing.

[0024] The mounting base of the present application cooperates with the fixing base and the socket, which is convenient for installation of the mounting base, and the fixing base is finally supported by multiple supporting units, so that each supporting unit only needs to provide a smaller force, and the installation is more stable.
