Reference picture 2 and Fig. 4, are illustrated to Intermediate Gray drive device 116.Drive the Intermediate Gray driving dress of handrail 38 116 are put to be connected with middle driven sprocket 115.As shown in Fig. 2 between middle driven sprocket 115 and Intermediate Gray drive device 116 Bindiny mechanism 116a is provided with, the bindiny mechanism 116a is used to transmit the rotary shaft 115b's from middle driven sprocket 115 Driving force.

The counter wheel 116b of Intermediate Gray drive device 116 is same by bindiny mechanism 116a and middle driven sprocket 115 Step ground rotation, so as to drive handrail 38.

(8) operating state of intermediate drive device 110

According to Fig. 2, the operating state of intermediate drive device 110 is illustrated.

First, midway drive sprocket wheel 112 is rotated by middle rotating device 111.

Next, when middle drive sprocket 112 rotates, being wound around midway drive sprocket wheel 112 and middle driven sprocket 115 Between the shuttling movement of central links 113.

Next, by making the shuttling movement of central links 113, the step roller 104a operations on chain link 113a are mounted in, and Thrust is assigned to step chain 104.

Next, as shown in figure 1, by assigning thrust to step chain 104, make to be connected with step chain 104 is multiple Step 30 is run along guide rail 25.

(9) oil supply structure

Next, being illustrated to the structure that lubricating oil is supplied to the central links 113 of intermediate drive device 110.

As shown in Fig. 2, Fig. 4, Fig. 5, the side of the top of intermediate drive device 110 is provided with oil tank 200.The oil tank 200 It is the tank body for storing lubricating oil.The oil pump 202 for supplying lubricating oil is provided with the bottom of the oil tank 200.Such as Fig. 2, Shown in Fig. 4, Fig. 5, the starting of oil pump 202 is provided with two fuel feed pumps 204,206.First fuel feed pump 204 is to positioned at go path Right side central links 113 top extension, and the outlet of lubricating oil from fuel feed pump 204 is supplied to central links 113.Separately Outside, the top extension of the central links 113 of fuel feed pump 206 to the left, the position in the top of the central links 113 positioned at left side From the outlet of fuel feed pump 206, central links 113 to the left supply lubricating oil.

Supply pipe 208 extends upward from oil tank 200.As shown in Fig. 9 to Figure 13, the upper end connection of the supply pipe 208 To the supply mouthful 210 in the upper shed of skirt panel 44.Supply mouthful 210 is circle, and its inner circumferential side is provided with what is formed by magnet Flange part 212.The lid 214 of disassembly ease is provided with supply mouthful 210.Lid 214 is circle, and be made of metal, The intrusion teat 216 for invading the inner circumferential side of flange part 212 is protruded from the back side.In addition, the peripheral part in lid 214 sets jagged Portion 218.

(10) fuel supply method

Next, being illustrated to the method that lubricating oil is supplied to central links 113.

It is continuous via fuel feed pump 204,206 from oil tank 200 by oil pump 202 during escalator 10 is run Ground or lubricating oil supplied to the central links 113 of left and right at intervals of set time.In addition, as shown in Figure 10, the envelope of lid 214 Closed supply mouth 210.Now, the lid 214 that metal is made is fixed in the flange part 212 with magnetic force, without coming off.

When operator checks escalator 10, check in oil tank 200 whether there is lubricating oil.In order to carry out the inspection, behaviour Author inserts flathead screwdriver the notch part 218 of lid 214, and the magnetic force of resistance flange part 212 pulls down lid 214, so as to open benefit To mouth 210.

After lid 214 are pulled down, lubricating oil is fed in oil tank 200 by operator from supply mouth 210.After supply, with lid 214 Closing feeds mouth 210 again.

(11) effect

According to present embodiment, in the case where not feeding lubricating oil, by the closing supply mouth 210 of lid 214, therefore will not The movement of passenger is hindered, it is also not eye-catching in addition.

Further, since lid 214 is fixed in flange part 212 by magnetic force, therefore it will not fall off.

Further, since being provided with notch part 218 on lid 214, therefore by the instrument of flathead screwdriver etc., it can facilitate Pull down lid 214 in ground.

In addition, when feeding lubricating oil, lid 214 can be opened and easily supply is moistened into oil tank 200 from supply mouth 210 Lubricating oil.

(12) variation

In the above-described embodiment, although supply mouth 210 and lid 214 for circle, but be not limited to that or Square, rectangle.

In addition, in the present embodiment, notch part 218 is provided with lid 214, to pull down lid 214, but simultaneously not only limit In this, notch part 218 can also be not provided with, operator is by stronger attraction lid 214, so as to be torn open from flange part 212 Lower cover 214.

[second embodiment]

Next, according to Figure 14 to Figure 18, being illustrated to the escalator 10 of second embodiment.

The difference of present embodiment and first embodiment is the disassembly and assembly structure of lid 214.In the present embodiment, In the inner peripheral portion of supply mouth 210, a pair of teat 220 is prominent to center position up and down.Lid 214 has：Circular closed plate 230, for closing supply mouth 210；Substantially the insertion plate 222 of rondelle, is inserted into inside supply mouth 210；And groove 224, It is arranged between closed plate 230 and insertion plate 222, and is set along periphery.As shown in figure 16, in insertion plate about 222 It is respectively arranged with the arc gap portion 226 of arc-shaped.In addition, being provided with linear rotation in the front of the closed plate 230 of lid 214 Conversion groove 228.

As shown in Figure 14 and Figure 17, when being installed to lid 214 on supply mouth 210, lack circular arc of the insertion plate about 222 Oral area 226 and the aligned in position of the teat 220 protruded from supply mouth 210, and insertion plate 222 is inserted into supply mouth in this condition 210.Then, teat 220 is corresponding with the position of the groove 224 of lid 214.Afterwards, operator uses the closed plate positioned at lid 214 220 positive rotation grooves 228, are rotated by 90 ° the lid 214 of circle, and make teat 220 from the position in arc gap portion 226 It is moved to the position for the groove 224 to be formed between closed plate 230 and insertion plate 222.Thus, as shown in Figure 15 and Figure 18, lid 214 will not come off from supply mouth 210.

On the contrary, when pulling down lid 214 from supply mouth 210, being rotated by 90 ° again with groove 228 using rotation, making teat The position in 220 alignment arc gap portions 226, so as to pull down lid 214.

Even the lid 214 of present embodiment, by rotating lid 214, also lid easily can be pulled down from supply mouth 210 214。

In addition, in the state of lid 214 is in closing, teat 220 is embedded into groove 224, therefore lid 214 will not take off Fall.

[variation]

In the above-described embodiment, the situation applied to escalator 10 is illustrated, but it is also possible to take and generation Ground be applied to moving sidewalk in.

More than, although an embodiment of the present utility model is illustrated, but the embodiment is as example What son was proposed, it is not intended that limit the protection domain of utility model.These novel embodiments can be in other various modes Implement, in the range of without departing from utility model objective, various omissions can be carried out, replace, change.These embodiments or its Deformation included in the protection domain or objective of utility model, also, utility model described in claims and In its equivalent protection domain.
