Description

Escalator

The present invention relates to an escalator.

The escalator (passenger conveyor) is connected to each step as the endless chain of steps connected with a number of steps is wound by the upper and lower floor sprockets. The rolled roller travels on the rail, and the step chain and a number of steps connected to the step chain circulate between the sprockets. In conventional escalator rails, the oil that has fallen on the rails flows along the rails and flows to the steps, making the steps easy to slip, so the steps need to be cleaned frequently.

In the escalator of Patent Document 1, in order to suppress oil leakage from the inside of the rail, an oil drain groove is formed over the entire length inside the rolling travel area of the step rail, and a drain attached to the lower end portion is provided. Oil was led through the lower machine room floor. Further, countermeasures against escalator oil leakage are also described in Patent Document 2 and Patent Document 3. In the escalator of Patent Document 2, the transfer surface of the chain roller and the transfer surface of the step roller are provided in the guide system, and further an oil collecting passage is provided to prevent the lubricating oil from dripping. In the escalator of Patent Document 3, a depression is provided in the middle of the front wheel guide portion and the rear wheel guide portion of the integrated rail that guides the front wheel and the rear wheel over the longitudinal direction of the escalator inclined portion, and falls from the chain. The oil to be stored in the dent.

In conventional escalator rails, oil that has fallen on the rails flows along the rails and flows to the steps, making the steps easy to slip, so the steps need to be cleaned frequently. As a solution to this problem, Patent Documents 1 and 3 use rails with oil drain grooves and depressions to suppress oil leakage from the rails to the steps. Moreover, in patent document 1, 2, the drain was provided in the terminal part of the rail lower part, or the oil collection flow path was provided in the outer side of the rail.

As in Patent Documents 1 and 2, if a route for collecting lubricating oil is newly provided, the number of parts and the part weight increase, and the material cost increases. In addition, in order to suppress oil leakage from the rail joint, it is necessary to perform caulking processing to prevent oil leakage at the rail joints, or it is necessary to manufacture the rails integrally without joints. It took time and effort to handle the oil leak.

The present invention has been made to solve the above-described problems, and aims to prevent oil leakage to the inside over the entire length of the rail.

The escalator according to the present invention includes a forward-side rail pair, which is a pair of forward-side rails, in which a driving-roller traveling unit that the driving roller travels and a tracking-roller traveling unit that the following roller travels are integrated, and an outward-side rail pair. And a return-side rail pair having two return-side rails on one side. The forward rail has an upper floor rail, a lower floor rail, and a connecting member that connects the upper floor rail and the lower floor rail, the lower end of the upper floor rail, and The upper end portion of the lower floor side rail portion has a cutting shape perpendicular to the longitudinal direction of the outward rail, or an inclined cutting shape inclined at substantially the same inclination angle other than 90 degrees with respect to the longitudinal direction of the outward rail. It is characterized by. The connecting member includes a rail connecting portion in which the lower end portion of the upper floor side rail portion and the upper end portion of the lower floor side rail portion are abutted with each other, and the back side of the upper floor side rail portion and the lower floor side rail portion. The lower end portion of the connecting member has a slope shape that descends from the longitudinal inner edge with a predetermined tilt angle and reaches the longitudinal outer edge.

According to the escalator of the present invention, the lower end portion of the connecting member disposed on the back side of the upper floor side rail portion and the lower floor side rail portion descends from the longitudinal inner edge with a predetermined inclination angle, and the longitudinal outer side. Since it has an inclined shape reaching the edge, oil leakage to the inside can be prevented over the entire length of the rail.

Hereinafter, the escalator in the first embodiment will be described with reference to FIGS. As shown in FIG. 1, the escalator 50 includes a truss 1, a step 2, a driving machine (not shown), a glass 3, a handrail 4, a chain 20, and the like made of a steel frame or the like. Although the chain 20 is connected in an annular shape, the upper side chain 75 on the upper side and the lower side chain 85 on the lower side in FIG. Step 2 of the escalator rides on an outward path rail 70 on which the passenger rides via the driving roller 5 and the follower roller 6, and is stepped by raising or lowering the outward chain 75 attached to the driving roller 5. 2 is moved.

The drive roller 5 and the forward chain 75 are integrated, and the forward chain 75 is refueled with a fueling device or the like. The forward side rail 70 on the forward side on which the passenger rides is formed by forming a thin plate as shown in FIG. 4, for example. As shown in FIGS. 3 and 4, the forward-side rail 70 is formed integrally with the driving roller traveling portion 70 A and the follower roller traveling portion 70 B as shown in FIGS. 3 and 4, thereby constituting the rail portion of the escalator 50. A bank-like driving roller-side raised portion 5a is formed inside the escalator (the longitudinal inner edge of the driving roller traveling portion 70A) on the surface on which the driving roller 5 travels. As shown in FIG. 3, the driving roller 5 is placed on the flat portion of the driving roller traveling portion 70 A of the forward rail 70, and the tracking roller 6 is placed on the flat portion of the tracking roller traveling portion 70 B of the forward rail 70. To drive step 2.

The forward rail 70 may be divided because it cannot be manufactured as a single rail due to the manufacturing reasons of the escalator. In this case, as shown in FIG. 5, it is divided into an upper floor side forward rail part (also referred to as an upper floor side rail part as appropriate) 71 and a lower floor side forward rail part (also referred to as a lower floor side rail part as appropriate) 72. Is done. Further, as shown in FIG. 6, the forward rail 70 is connected to a connecting member (also referred to as a rail connecting member as appropriate) in a rail connecting portion 76 to which an upper floor side forward rail portion 71 and a lower floor side forward rail portion 72 are connected. ) 10 and fixing plate 16 are interposed and fixed with bolts 9 or the like. Specifically, the upper floor side forward rail portion 71 and the lower floor side forward rail portion 72 are fixed by being sandwiched between the connecting member 10 and the fixing plate 16 in the rail connecting portion 76. The connecting member 10 includes a rail connecting portion 76 in which the lower end portion 71c of the upper floor side rail portion 71 and the upper end portion 72c of the lower floor side rail portion 72 are abutted with each other, and the upper floor side rail portion 71 and the lower portion. It is arranged on the back side of the floor side rail portion 72.

This connecting member 10 has a shape in which the cut shape on the lower floor side is cut in a direction spreading outward as seen from above the escalator. That is, the lower end portion 10a of the connecting member 10 has a shape that is inclined so that the inside is at a high position and the outside is at a low position as viewed from above the escalator. In other words, the connection member 10 has a shape in which the outer side of the connection member 10 extends downward from the inner side, and the length of the outer end 10c is longer than the inner end 10d. ing. The inclined lower end portion 10a of these connecting members 10 has a function of guiding and dropping the dropped oil that has fallen on the forward path side rail 70 to the oil pan 14 (see FIG. 14) or the like, as will be described later.

In the escalator 50 according to the first embodiment, as shown in FIG. 3, the oil supplied to the forward path side chain 75 flows like the path 21 without passing through the driving roller side raised portion 5a. It flows down to the outside of the driving roller traveling portion 70A. Further, as shown in FIG. 5, the oil transmitted from the upper floor side in the rail connecting portion 76 is also the same as the rail connecting portion 76 and the driving roller running portion other than the rail connecting portion 76 (the driving roller running portion 70 A, the follow After traveling on the back side of the rail through the outside of the roller running portion 70B), the rail connecting portion 76 enters the lower floor side outward rail portion 72 of the outward path side rail 70, and the outer end portion 10c and inner end portion of the rail connecting member 10 It flows through 10d. The oil flowing through the outer end portion 10c of the rail connection member 10 flows like a path 22, and the oil flowing through the inner end portion 10d of the rail connection member 10 is inclined lower end 10a of the rail connection member 10 like a path 23. Oil flows down along. Also in the lower floor side forward rail portion 72, the oil supplied to the forward side chain 75 flows like the path 21 without passing through the driving roller side raised portion 5a, and flows down to the outside of the driving roller traveling portion 70A.

Further, as shown in FIG. 7, the oil that has flowed along the driving roller side raised portion 5a of the driving roller traveling portion 70A enters the lower floor side outward rail portion 72 of the outward rail 70 from the rail connecting portion 76, and the rail It flows through the outer end 10c and the inner end 10d of the connecting member 10. The oil flowing through the outer end 10c of the rail connection member 10 flows like a path 24, and the oil flowing through the inner end 10d of the rail connection member 10 is inclined lower end 10a of the rail connection member 10 like a path 25. Oil flows down along.

Since the oil transmitted from the upper floor side flows along the outer periphery of the rail connection member 10 and finally flows down to the outside of the outward path side rail 70, the escalator 50 according to the first embodiment adheres to the tread in step 2. Therefore, it is possible to improve safety such that slipping when the passenger gets on the tread surface can be suppressed. Further, the escalator 50 according to the first embodiment can save the trouble of cleaning step 2.

Further, the escalator 50 according to the first embodiment is provided with the driving roller side raised portion 5a in the driving roller traveling portion 70A, so that when the chain is traveled with the steps removed in escalator assembly or maintenance, the chain 20 Therefore, the safety of escalator travel can be improved.

For this reason, the escalator 50 of Embodiment 1 can prevent the dripping of the oil to step 2, can improve safety | security, and can save the effort of step cleaning. In addition, the escalator 50 according to the first embodiment is configured such that the escalator is assembled and maintained by the driving roller side raised portion 5a provided in the driving roller running portion 70A and the follower roller side raised portion 6b provided in the following roller running portion 70B. Since the chain 20 can be prevented from being removed when the chain is run with the step removed, the safety of escalator running can be improved.

Further, the outward rail 70 may be the outward rail 70 of the third modification shown in FIG. The forward path rail 70 of the third modified example has raised portions (the driven roller side raised portion 5a in FIG. 4 and the follower in FIG. 8) on both the drive roller side of the drive roller running portion 70A and the follower roller side of the follower roller running portion 70B. This is an example in which there is no roller-side raised portion 6b). Even in this case, the escalator 50 according to the first embodiment is configured so that the lower floor side cut shape is cut by the rail connecting member 10 which is cut in a direction extending outward as viewed from above the escalator. By connecting the section 71 and the lower floor side forward rail section 72, the oil supplied to the chain 20 flows down to the outside of the driving roller traveling section 70A at the rail connection section 76 as in FIG. Can be prevented from dripping.

As described above, the escalator 50 according to the first embodiment is the two of the forward rails 70 in which the driving roller traveling portion 70A where the driving roller 5 travels and the tracking roller traveling portion 70B where the tracking roller 6 travels are integrated.

Can be continuously cut obliquely by cutting the strip-shaped steel material obliquely. Since the escalator 50 of Embodiment 2 can manufacture the rail connection member 10 by continuously performing oblique cutting, the processing time of the rail connection member 10 can be reduced.

Embodiment 3 FIG.
FIG. 12 is a diagram illustrating a connection portion of the outward path side rail 70 according to the third embodiment of the present invention. The forward rail 70 shown in FIG. 12 includes an upper floor forward rail portion 71 having an inclined lower end portion 71c and a lower floor side forward rail having an inclined upper end portion 72c facing the lower end portion 71c for both the left and right rails. A portion 72 is provided. The inclination angle of the lower end 71c of the upper floor side forward rail portion 71 may be slightly different from the inclination angle of the upper end portion 72c of the lower floor side outward rail portion 72, that is, it may be substantially the same. The forward-side rail 70 in FIG. 12 is lowered at a predetermined inclination angle in the same direction in both the left and right rails and is cut into an inclined shape. In the escalator 50 according to the third embodiment, the cut surface of the inclined lower end portion 71c and the upper end portion 72c of the lower floor side forward rail portion 72 opposed thereto collides with the inclined lower end portion 71c on the upper floor side ( It is formed in a slanted shape. As a result, the escalator 50 of the third embodiment has the left and right rails (outward rail 70) fixed to the truss 1 when the escalator 50 once assembled in the factory is divided and rejoined at the installation site. However, since the rail inclination direction in the rail connecting portion 76 is the same direction, the work of matching the cross sections of the left and right rails can be performed efficiently. Note that the inclination angles of the left and right rails may be different from each other.

Furthermore, the escalator 50 according to the third embodiment may be configured such that the connection between the inclined lower end portion 71c of the upper floor side forward rail portion 71 and the inclined upper end portion 72c of the lower floor side forward rail portion 72 is in close contact. A rail gap 70G of about 1 to 3 mm may be provided. Since the escalator 50 according to the third embodiment is provided with the rail gap 70G, it is not necessary to attach the upper floor side forward rail portion 71 and the lower floor side forward rail portion 72 together. Can be relaxed. In addition, the escalator 50 according to the third embodiment has an abutting (butting) portion that is cut in an inclined manner, so that when the rollers (the driving roller 5 and the following roller 6) pass through the rail gap 70G, the upper floor side The escalator 50 can be operated without abnormal noise or vibration by transferring to both the outward rail portion 71 and the lower floor-side outward rail portion 72 without passing through the rail gap 70G.
