Description

The present invention relates to an escalator with a work platform and a escalator with a work platform connection function, in which a work platform is detachably coupled to an escalator having a step plate.

  Conventionally, it has been considered to install a work platform on a step portion of an escalator. The work platform is used by an operator in a state where it is installed on a step part of the escalator in order to maintain and inspect lighting equipment and the like on the ceiling part of the escalator.

  For example, FIG. 7 is a perspective view showing a working scaffold that is installed on an escalator described in Patent Document 1. FIG. The step ladder 10, which is a work platform shown in FIG. 7, is installed on the two step plates 12 constituting the step portion of the escalator 11, and the operator rides on the step ladder 10 to illuminate the ceiling portion. The equipment can be maintained and inspected. The stepped stepladder 10 includes two stepladder members 14a and 14b. The two stepladder members 14a and 14b are different in length from each other, and a plurality of step bars 16 are provided on each of the two stepladder members 14a and 14b for a person to move up and down. The top portions of the two stepladder members 14 a and 14 b are connected by a connecting rod 18. Further, the leg portions of the two stepladder members 14 a and 14 b are fixed to the two step plates 12 by the leg fixing means 20.

  The leg fixing means 20 includes a leg fixing part 22 for inserting and fixing the leg part of the stepped stepladder 10, and a fixing plate 24 having a convex part (not shown) fitted to the concave part of the upper surface of the step board 12 on the lower surface. It is composed. A moving plate (not shown) is disposed in a T-shaped groove (not shown) provided on the lower surface of the fixed plate 24, and the moving plate is moved with respect to the fixed plate 24 by a moving lever (not shown). The side surface of the convex portion and the side surface of the concave portion of the step plate 12 can be brought into contact with each other. As a result, the fixed plate 24 is fixed to the step plate 12, and the fixed plate 24 does not move on the step plate 12. That is, when fixing the fixed plate 24 to the step plate 12, the convex portion of the fixed plate 24 and the convex portion of the moving plate are brought into contact with both side surfaces of the concave portion of the step plate 12 and pressed in opposite directions. The fixed plate 24 and the moving plate are fixed on the step plate 12.

  When the step ladder 10 which is a working platform described in Patent Document 1 is installed on the escalator 11, a frictional force generated between the concave portion of the step plate 12 and the convex portion of the fixed plate 24 and the movable plate. Thus, the fixing plate 24 is fixed to the step plate 12, and the stepped stepladder 10 is fixed to the step plate 12. For this reason, when foreign matter such as dust or oil is adhered to the step plate 12, foreign matter or oil enters between the concave portion of the step plate 12 and the convex portion of the fixed plate 24 and the movable plate, thereby It may not be possible to effectively prevent the stepladder 10 from becoming unstable because the fixing plate 24 is displaced with respect to the step plate 12 because the frictional force between the step and the projection cannot be sufficiently secured.

  For example, when performing maintenance and inspection of lighting equipment or the like on the ceiling, the operator loses balance during work on the stepladder 10, and the fixing plate 24 is fixed to the fixing plate 24 of the stepping step 10 with respect to the step plate 12. When a large force that shifts the position of the stepladder 10 is applied, it is difficult to effectively prevent the legs of the stepladder 10 from shifting on the step board 12. On the other hand, in order to sufficiently increase the frictional force between the concave part and the convex part, the contact area between the concave part and the convex part is increased, and the convex part is changed to the concave part in order to increase the frictional force. It is also conceivable to provide a pressing mechanism for pressing with a large force in the fixed plate 24 portion. However, in this case, the moving plate and the fixed plate 24 become large, and there is a possibility that the carrying operation for installing the stepladder 10 cannot be performed by one person.

  In consideration of the possibility that the stepped stepladder 10 may be shifted on the step board 12, an assistant other than the worker who works on the stepped stepladder 10 may support the stepped stepladder 10 from below. In this case, another assistant is required, and the cost required for maintenance may increase.

An object of the present invention is to enable an escalator with a work platform and an escalator with a work platform combination function to perform installation work of the work platform and work using the work platform alone. The purpose is to more effectively prevent the scaffolding from being displaced from the step board.

In a state of being fitted to the upper outer side, the through hole formed in the cylindrical portion 60 and the first adjustment hole 54 of the distal end side slide element 46 (see FIG. 2 and the like) are aligned. Then, a nut (not shown) is coupled to the tip of the bolt 52 in a state where the bolt 52 is inserted into the through hole formed in the cylindrical portion 60 of the stepladder members 14a and 14b and the first adjustment hole 54. Accordingly, the leg lower portions of the stepladder members 14a and 14b are detachably coupled to the leg fixing portions 38, respectively. Thereby, the escalator with a working platform is comprised. When maintaining and inspecting the lighting equipment and the like on the ceiling of the escalator 11, an operator rides on the uneven platform 26 in this state.

  On the other hand, when removing the uneven scaffolding base 26 from the escalator 11, the bolt 52 and the nut 58 which connect the leg part fixing | fixed part 38 and the stepladder members 14a and 14b are removed. Then, as shown in FIGS. 3 to 5, the length of the leg fixing portion 38 is reduced, and the length adjusting bolt 52 and the nut 58 (FIGS. 4 and 5) are coupled to the leg fixing portion 38. Then, the leg fixing part 38 is swung so as to be directed in the length direction of the storage part 36 (the left-right direction in FIGS. 2 to 4) around the support pin 42, and the leg fixing part 38 is moved to the storage part 36.

  Further, as shown in FIG. 3, a step board constituting cover 62 can be mounted on the upper portion of the storage portion 36. 3 is a cross-sectional view taken along the line AA in FIG. 4 showing a state where the upper portion of the storage portion 36 is closed by the step board constituting cover 62. FIG. 4 is a state where the step board constituting cover 62 is removed in FIG. FIG. 5 is a cross-sectional view taken along the line B-B in FIG. 4.

  As shown in FIG. 3, a recess is formed on the lower surface side of the step board 12 on the support pin 42 side (right side in FIG. 3) around the opening 34 of the step board 12, and the periphery of the opening 34 of the step board 12. Thus, a step portion is formed on the upper surface side of the step board 12 on the drawing side (left side in FIG. 3) of the tip side slide element 46. And the convex parts 64 and 66 provided on the lower surface side and the upper surface side of both ends in the length direction (left and right direction in FIG. 3) of the step board constituting cover 62 are engaged with the concave portion and the step portion. The opening 34 at the top of the storage portion 36 is closed by a step board constituting cover 62.

  Further, a screw hole 68 (FIG. 4) is formed on the upper surface of the step portion located in the periphery of the opening 34 of the step plate 12, and a screw 70 penetrating the end portion of the step plate structure cover 62 (FIG. 3) is attached to the screw hole. 68 is screwed together. Thereby, the step plate structure cover 62 is fixed to the step plate 12. In this state, the upper surfaces of the step board 12 and the step board constituting cover 62 are substantially flush, that is, substantially located on a single virtual plane. Further, the step board constituting cover 62 is made of the same material as that of the step board 12.

  As described above, in the present embodiment, the upper opening 34 of the storage portion 36 can be closed by the step plate structure cover 62 (FIG. 3) in a state where the stepped scaffold 26 (FIG. 1) is removed from the escalator 11. It is said. During normal use of the escalator 11, an occupant can get on the step board constituting cover 62 without any trouble. In addition, when installing the uneven platform 26 (FIG. 1) on the escalator 11 for maintenance inspection of the ceiling lighting equipment, etc., the screws 70 (FIG. 3) for fixing the step board component cover 62 are removed. The step plate structure cover 62 is removed from the step plate 12.

  In addition, when adjusting the height of the uneven platform 26, first, the lower portions of the leg portions of the stepladder members 14a and 14b are coupled to the leg fixing portion 38 with bolts 52 and nuts (not shown), The total length of the leg fixing portion 38 can be changed by pulling out the distal end side slide element 46 from the proximal end side slide element 44. The number of first adjustment holes 54 formed in the distal end side slide element 46 is not limited to three, but may be two or more than four.

  According to such an escalator with a working platform according to the present embodiment, when the uneven platform 26 is installed with the uneven platform 26 removed from the escalator 11, the storage portion 36 (FIGS. 2 to 5) is installed. ), The lower portions of the stepladder members 14a and 14b may be connected by bolts 52 and nuts, and the legs are fixed to the step board 12 every time the stepped platform 26 is installed. It is not necessary to join the portions 38. Further, since the leg fixing part 38 is located below the opening 34, it is not necessary to couple the leg fixing part 38 to the step board 12 so that it can be easily removed. For this reason, the leg fixing portion 38 can be coupled to the storage portion 36 with a coupling structure having a sufficient coupling strength, not a coupling structure using a frictional force for facilitating removal. For this reason, when an operator works on the uneven platform 26, it is not necessary for the assistant to support the uneven platform 26 from below, and it is more effective that the uneven platform 26 is displaced with respect to the step board 12. Can be prevented.

  Unlike the case where the step ladder described in Patent Document 1 is installed on an escalator, the joint strength between the step platform 26 and the step board 12 is reduced in the joint portion due to foreign matters such as dust adhering to the step board 12 or oil. The decrease in frictional force has no effect. As a result, the work using the uneven platform 26 can be easily performed by one person, and safety during the work can be more effectively ensured.

  In addition, according to the escalator with a scaffold for work of the present embodiment, unlike the case where the step ladder described in Patent Document 1 is installed on the escalator, when the step platform 26 is coupled to the step board 12. In order to obtain a high bonding strength, it is not necessary to use a pressing mechanism for obtaining a large frictional force, a large fixed plate, and a moving plate, and it is possible to easily carry and install the uneven platform 26 alone.

  Further, in the present embodiment, the step board lower fixing portion is the storage portion 36 that stores the leg fixing portion 38, and the upper opening portion of the storage portion 36 is removed with the stepped scaffold 26 removed from the escalator 11. 34 can be closed by a step plate structure cover 62. Therefore, an occupant of the escalator 11 can get on the step board constituting cover 62, and normal use of the escalator 11 is not hindered by the leg fixing portion 38.

  Further, the stepped platform 26 connects the top portions of the two stepladder members 14a and 14b by the connecting portion 30, and the two stepladder members 14a and 14b are different in length from each other and are connected to the two stepladder members 14a and 14b. Since the step bars 16 for raising and lowering the person are provided, the operator can easily get on the step platform 26 in a well-balanced manner even though the step plate 12 of the escalator 11 is stepped. , Work more stably.

  Further, since the leg fixing part 38 is supported on the support pin 42 supported by the wall plate part 40 (FIG. 5) constituting the storage part 36 so as to be swingable around the support pin 42, the leg fixing is performed. When the stepped platform 26 is coupled to the portion 38, the leg fixing portion 38 is swung around the support pin 42, so that the orientation of the leg fixing portion 38 is changed to the leg fixing portion 38. , 14b can be easily changed so as to be easily combined. For this reason, the uneven platform 26 can be easily coupled by the escalator 11. Further, with the stepped platform 26 removed from the escalator 11, the leg fixing part 38 is swung around the support pin 42 to retract the leg fixing part 38 below the opening 34. On the other hand, when the stepped scaffold 26 is coupled to the escalator 11, the leg fixing part 38 is swung and protruded above the opening 34, thereby making the stepped scaffolding 26 to be fixed to the leg fixing part 38. Can be easily combined.

  Further, the leg fixing portion 38 is constituted by a proximal end side slide element 44 and a distal end side slide element 46, and the distal end side slide element 46 can be slid relative to the proximal end side slide element 44. By supporting this, the entire length of the leg fixing portion 38 can be expanded and contracted. Therefore, when the escalator 11 is in a normal use state, the leg fixing portion 38 can be stored in the storage portion 36, and when the uneven scaffolding base 26 is coupled to the escalator 11, the total length of the leg fixing portion 38. Therefore, the length of the stepladder members 14a and 14b of the uneven platform 26 can be shortened. For this reason, the transportation work of the uneven platform 26 can be performed more easily.

  Further, three first adjustment holes 54 for length adjustment are formed in the distal end side slide element 46 constituting the leg fixing portion 38, and second adjustment holes 56 are formed in the proximal end side slide element 44. The bolt 52 is prevented from coming out of the first adjustment hole 54 and the second adjustment hole 56 in a state where the bolt 52 is inserted into the first adjustment hole 54 and the second adjustment hole 56. For this reason, the full length of the leg fixing | fixed part 38 can be adjusted by changing the position of the 1st hole 54 for inserting the volt | bolt 52. FIG. As a result, without changing the length of the stepladder members 14a, 14b of the stepped platform 26, the height position of the operator during work can be easily changed according to the height of the ceiling portion, etc. 26 can be easily performed.

[Second Embodiment]
FIG. 6: has shown the partial schematic perspective view of the escalator with a scaffold for work of the 2nd Embodiment of this invention. As shown in FIG. 6, in the case of the present embodiment, the top portions of the two stepladder members 14a and 14b are connected by a substantially flat work table 72 which is a connecting portion. The work table 72 is supported on the upper portions of the stepladder members 14a and 14b so as to be swingable by a connecting portion such as a pin (not shown).

Also in the case of the present embodiment, the length of the wall plate portion of the distal end side slide element 46 constituting the leg fixing portion 38 is the same as in the first embodiment shown in FIGS. Each of the three first adjustment holes 54 for adjustment is formed, and the second adjustment hole 56 is formed in the wall plate portion of the proximal end side slide element 44, and the first adjustment hole 54 and the second adjustment hole 54 are formed. A nut 58 is coupled to the tip of the bolt 52 with the bolt 52 inserted through the hole 56. Therefore, by changing the position of the first adjustment hole 54 into which the bolt 52 is inserted, the overall length of the leg fixing portion 38 can be adjusted, and the stepladder member of the uneven scaffolding base 26 as in the present embodiment. Even when the top portions of 14a and 14b are connected by the substantially flat work table 72, it becomes easy to level the upper surface of the work table 72.
