It can be seen that the installation position of the handrail speed monitoring device 100 can be located at the return side of the escalator 200 and near the inner side surface at the upper horizontal portion, and the handrail speed monitoring device 100 is located directly above the handrail 210, which does not affect the normal operation of the escalator 200 and the riding experience of passengers. Of course, in other embodiments, the handrail speed monitoring apparatus 100 can be installed at other positions of the escalator 200.
It should be noted that the handrail speed monitoring apparatus 100 may be one, and cloth is installed on either side of the escalator 200. Preferably, one escalator 200 should be installed on each side, and the detection accuracy and reliability are further improved in a two-point monitoring data cooperation manner.
As shown in fig. 3, a handrail speed monitoring apparatus 100 shown for an embodiment of the present application includes: the device comprises a mounting frame 10, a carrying wheel 20, an elastic pressing assembly 30, a speed measuring wheel 40 and a speed measuring sensor 50. The carrying wheel 20 is rotatably arranged on the mounting rack 10; the elastic pressing assembly 30 is arranged on the mounting frame 10; the speed measuring wheel 40 is rotatably arranged on the elastic pressing assembly 30, and the speed measuring wheel 40 and the carrying wheel 20 are used for respectively clamping two opposite sides of the handrail 210; the speed measuring sensor 50 is arranged opposite to the speed measuring wheel 40.

Therefore, the upper and lower surfaces of the handrail belt 210 are respectively clamped and fixed by the carrying wheels 20 and the speed measuring wheels 40, so that the degree of freedom of the handrail belt 210 can be well limited, the vibration of the handrail belt 210 caused by manufacturing and installation dimension errors is reduced or even inhibited, the measurement position relation of the speed measuring sensor 50 which is always reliable and is opposite to the speed measuring wheels 40 is ensured, the measurement precision of the speed measuring sensor 50 is improved, and the safety problem that the safety switch is triggered by mistake due to large measurement errors is avoided.
In the above embodiment, when the handrail 210 is rotated, the carrier roller 20 and the velocity measuring roller 40 are rotated in synchronization with the handrail 210 by the contact friction without interference with the handrail 210. And at this time, the rotation speed of the tachometer wheel 40 is equal to the running speed of the handrail 210, and the tachometer sensor 50 measures the rotation speed of the tachometer wheel 40 to indirectly obtain the running speed of the handrail 210, so that the accuracy of the detection result is not affected.
It should be noted that, in order to avoid the slipping between the velocity measuring wheel 40 and the handrail 210, which causes the rotation speed of the velocity measuring wheel 40 to be actually less than the running speed of the handrail 210, the velocity measuring wheel 40 is preferably made of a material with a high friction coefficient and a low cost, such as nylon or polyurethane, so as to avoid the above problems.
With continued reference to fig. 3 and 4, in an embodiment, the mounting frame 10 includes a first mounting plate 11, and the first mounting plate 11 defines a first slotted hole 12 for assembling and connecting with the escalator 200 or moving walkway. Through designing first slotted hole 12 on first mounting panel 11, can conveniently adjust the mounted position of handrail area speed monitoring equipment 100, guarantee to carry the relative both sides that riding wheel 20 and tachometer wheel 40 can accurate centre gripping handrail area 210 to fine suppression handrail area 210 vibrates, guarantees the testing result accuracy. Alternatively, in other embodiments, the first long slot 12 may also be formed in a cross-shaped structure to satisfy the requirement of adjusting the installation position in multiple directions.
As shown in fig. 6 and 7 for the escalator 200, the handrail 210 used therein generally has both the C-shaped handrail 210 and the V-shaped handrail 210, and thus the rim of the velocity measuring wheel 40 is recessed to form the annular wheel groove 41. That is, the speed measuring wheel 40 is formed in an H-shaped or type-shaped structure at this time, so that the speed measuring wheel 40 can be applied to any one of the C-shaped or V-shaped handrail belts 210, that is, the application range of the raised handrail belt speed monitoring apparatus 100.
Referring to fig. 3 and fig. 5, in an embodiment, the elastic pressing assembly 30 includes a fixing frame 31, the tachometer wheel 40 is rotatably disposed on the fixing frame 31 through a wheel axle 70, and the tachometer sensor 50 is disposed on the fixing frame 31 and opposite to the tachometer wheel 40. At the moment, the speed measuring wheel 40, the speed measuring sensor 50 and the fixing frame 31 can be assembled and integrated into a whole, so that the whole is convenient to assemble, disassemble and replace; in addition, because the three are installed on the fixing frame 31 at the same time, the tachometer wheel 40 and the tachometer sensor 50 can keep a relatively fixed relation, which is beneficial to ensuring the speed detection precision of the tachometer sensor 50.
Referring to fig. 3, 6 and 7, as described in the above embodiments, the speed wheel 40 is preferably made of nylon or polyurethane, which has a low feedback sensitivity to the speed sensor 50 although the friction coefficient is large to prevent the speed wheel from slipping with the handrail 210. In view of this, in an embodiment, the handrail speed monitoring apparatus 100 further comprises a sensing member 60 disposed on the tachometer wheel 40, and the sensing member 60 is in triggering engagement with the tachometer sensor 50. Specifically, the sensing member 60 is formed as a cross-shaped metal member, such as copper or steel, and is fixed on the wheel end surface of the tachometer wheel 40 by means of adhesion or screwing, and is opposite to the tachometer sensor 50, so that the tachometer sensor 50 and the sensing member 60 can constitute a speed sensing mechanism with reliable operation. Of course, it should be noted that the sensing element 60 may have other structural shapes in other embodiments, such as a circular ring shape.
Referring to fig. 3, fig. 4 and fig. 8, in an embodiment, the fixing frame 31 includes a first fixing plate 32, a coupling plate 33 and a second fixing plate 34, which are sequentially connected to form a U-shaped structure, the first fixing plate 32 is provided with a second assembling hole 321, the second fixing plate 34 is provided with a third assembling hole 341, the axle 70 is provided with a first step 71, an optical axis section 72 and a second step 73, which are sequentially arranged, one end of the axle 70 is rotatably inserted into the second assembling hole 321, the first step 71 abuts against the first fixing plate 32, the other end of the axle 70 is rotatably inserted into the third assembling hole 341, and the velocity measuring wheel 40 is rotatably sleeved on the optical axis section 72 and can reciprocate between the first fixing plate 32 and the second step 73 along the axial direction of the axle 70. Because the friction resistance of the speed measuring wheel 40 and the optical axis section 72 is low, and preferably, the friction resistance is in a clearance fit relationship, when the hand strap 210 swings left and right, the speed measuring wheel 40 can axially slide left and right along the hand strap 210 on the optical axis section 72, so that the speed measuring accuracy when the hand strap 210 swings left and right is ensured. The first step 71 abuts against the first fixing plate 32, so that the wheel axle 70 can be installed, positioned and limited. The second step 73 is used for limiting the left and right slippage of the tachometer wheel 40.
In order to ensure that the axle 70 is firmly installed, the two ends of the axle 70 extending out of the first fixing plate 32 and the second fixing plate 34 are respectively provided with external threads, and can be directly locked and fixed through nuts.
In addition, in order to facilitate the integral assembly and disassembly of the axle 70 and the flywheel 40, an access notch 342 is formed on a hole wall of at least one of the second assembly hole 321 and the third assembly hole 341. It is understood that the second and third fitting holes 321 and 341 may be, but are not limited to, C-shaped holes or U-shaped holes.
It should be emphasized that the fixing frame 31 has to have a sufficient width to cover the sensing portion of the speed sensor 50 and the speed wheel 40, so as to avoid the problem that the measuring accuracy and the service life are affected by rainwater and the like directly wetting the speed sensor 50 and the speed wheel 40 when used in an outdoor environment.
With continued reference to fig. 3 to 5, the mounting bracket 10 further includes a second mounting plate 13 connected to the first mounting plate 11, and a third mounting plate 14 connected to the second mounting plate 13. First mounting panel 11 and second mounting panel 13 mutually perpendicular, third mounting panel 14 and second mounting panel 13 mutually perpendicular for the structure of mounting bracket 10 is more compact, and occupation space is little, and is easy to assemble. The elastic pressing component 30 further includes a sliding shaft 35 connected to the coupling plate 33 and the third mounting plate 14, a mounting seat 36 disposed on the sliding shaft 35, an elastic pressing component 37 disposed between the mounting seat 36 and the third mounting plate 14, and a limiting rod 38 connected to both the first fixing plate 32 and the second fixing plate 34, wherein the second mounting plate 13 is provided with a fourth assembling hole, and one end of the limiting rod 38 extends out of the first fixing plate 32 and is inserted into the fourth assembling hole. When the handrail driving device is installed, the position of the limiting rod 38 is adjusted to enable the elastic pressing piece 37 to generate pre-pressing amount, and the elastic force generated by the elastic pressing piece 37 can be transmitted to the speed measuring wheel 40 through the fixing frame 31, so that the speed measuring wheel 40 can reliably press the handrail 210.

The shorter end is inserted into the fourth assembly hole, and the two opposite sides of the second mounting plate 13 are locked and fixed by two second locking nuts.
The sliding shaft 35 is also provided with external threads at both ends thereof. One end of the slide shaft 35 can thus be locked and fixed to the coupling plate 33 by means of two third lock nuts. The mounting seat 36 is locked and fixed at the middle position of the sliding shaft 35 through a fourth lock nut, so that the mounting seat 36 can be vertically matched with the third mounting seat 36 to press the elastic pressing piece 37 to generate pre-pressing deformation.
Further, the fourth assembling hole is preferably a second slotted hole 131. When the fourth assembling hole is designed to be a long slotted hole structure, and the length direction of the long slotted hole is the linear direction from the speed measuring wheel 40 to the carrying supporting wheel 20, when the hand strap 210 jumps up and down, the speed measuring wheel 40, the fixed frame 31 and the limiting rod 38 can synchronously jump up and down along with the hand strap 210 under the elastic pressure of the elastic pressing piece 37, and the speed monitoring requirement when the hand strap 210 jumps up and down is met; and the speed measuring sensor 50 is always kept static relative to the speed measuring wheel 40 in the whole jumping process, so that the measuring precision is ensured. And the sliding shaft 35 is provided with a sliding-accommodating section extending out of the third mounting plate 14. So that the sliding shaft 35 can slide up and down on the third mounting plate 14 to provide the travel and track for the elastic pressing assembly 30.
However, it should be noted that a certain distance is required between the third and fourth opposite lock nuts, so as to avoid collision interference when the slide shaft 35 slides up and down.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
