Abstract

PURPOSE:To reduce the stay of oil which dropped on a scaffold board and easily and safely carry out a maintenance operation on the scaffold board by providing a scaffold board having oil dropping holes on the oil pan of a step-board inverting portion. CONSTITUTION:Oil which has dropped from a step-board chain 3, etc., in the vicinity of the inverting portion 2a of step boards 2 is collected in an oil pan through the wire mesh 6b of a scaffold board 6. Refuse on the step boards 2 falls at the inverting portion 2a and large pieces out of the refuse are caught by the wire mesh 6b. As a result, the stay of oil which dropped on the scaffold board 6 is reduced reducing the removing operation of oil and refuse at the time of a maintenance operation to facilitate the maintenance operation.

Description

[Detailed Description of the Invention] [Industrial Contribution Field] The present invention relates to a maintenance equipment for a passenger conveyor, particularly to improving the maintenance workability of the inner end of the main frame. [Prior Art] Fig. γ and Fig. Figure 8 is, for example, Utsukai Sho 5 9-112117.
In the passenger conveyor shown in Publication No. 6, in the figure, (11 is the main frame, (2) is a large number of fFL treads arranged endlessly in the main frame (1), and the main frame (1> Inverted part at the end (2!1
), and 13) is a tread chain connecting the treads (2). 1st pull is a rail provided along the length of the main frame {1) to guide the trochanter of the treadle (2), and (5) is a treadle chain (3
A conventional passenger conveyor, which has an oil pan that receives oil dripping from the conveyor belt, is constructed as described above. Drive machine (
(not shown) through the tread chain {3} to the tread (2)
is driven, and the g4 oil of the tread chain {3} drips from the rail +41. A small amount of this oil is collected in the oil pan {5}. In addition, in the conventional passenger conveyor installation/curve as described above, maintenance work is performed by entering the end of the main frame (1).
}The oil on the top falls down at the reversing part (2a) and accumulates with oil on the corresponding part of the reversing part (25) of the oil pan {5}. Therefore, during maintenance, the oil on the oil pan/(5) must be cleaned before maintenance work. A device is needed to remove the dirt and debris. There was a problem that it took a lot of time, and the oil pan (5)
Nisakut! There was a problem in that the oil pan F51 required rigidity as a work platform for people to ride on, which increased molding costs.This invention was made to solve this problem, and the main frame end [Means for Solving the Problems] The maintenance equipment for a passenger conveyor according to the present invention aims to provide a maintenance equipment for a passenger conveyor that facilitates internal maintenance work. A foothold board with a base plate is installed between the oil pan and the footboard on the lower side of the circulation at the end of the main frame.

[Effect]

In the maintenance and electrical installation of the passenger conveyor constructed as described above, the accumulation of dripped oil on the scaffolding board is reduced. In the figure, the same symbols as in Figures 1 and 8 indicate corresponding parts.

The supporting piece (+

In the passenger conveyor maintenance curvature K, which is installed between the oil pan {5} at the longitudinal end of the main frame (1) and the treadle (2) on the lower side of the circulation, the treadle is (2) The oil dripping from the tread chain {3} near the reversing part (c) passes through the wire mesh (sb) of the scaffolding board (6) and is collected in the tenth chain {5). The garbage falls in the reversing section (c), but the largest pieces of this garbage are gold M [! (Sb) and dripped onto the scaffolding board (6) is reduced, and the work required to remove oil and debris during maintenance is reduced, making maintenance work easier.

Also, since maintenance work is performed on the scaffolding board (6),
The ten-irvan {5} can be manufactured easily and inexpensively without compromising the strength and rigidity of the scaffolding. Figure 4 shows another embodiment of the present invention, and in the figure, Figure 3 and The same reference numerals indicate corresponding parts, and (61 is a scaffold board made of a plate-like body assembled with a large number of steel plate crosspieces (6C), i.e., a scaffold board 16 having an oil drip hole) is provided. , Although detailed explanation is omitted, this also applies to the real plum example in Figure 4. It is clear that the same effects as the embodiments shown in the embodiments shown in FIGS. 11 to 3 can be obtained. FIGS. The same symbols as in the figure indicate corresponding parts, t

It is clear that the same effect as the embodiment of FIG. 3 can be obtained.

[Effects of the invention 1] As mentioned above, a scaffolding board having an oil dripping hole is provided above the sill van of the reversing part of the tread, and the dripping oil is retained on the scaffolding board. The oil pan can be easily and safely maintained on the scaffolding board, and the oil pan can be simplified to reduce the required flow rate, which will have the effect of reducing manufacturing costs.
