Description

  The present invention relates to installation of passenger conveyors represented by escalators and moving walkways.

  For example, a passenger conveyor may be renewed by removing an old passenger conveyor that has become obsolete and installing a new passenger conveyor at the same location. As a renewal method, when the existing passenger conveyor is removed, the main body frame (hereinafter referred to as the existing main body frame) is left without being removed, and the passenger conveyor main body (hereinafter referred to as the new conveyor main body) is incorporated into the existing main body frame. Are known. This construction method has advantages such as excellent installation of the passenger conveyor and cost reduction.

  When incorporating a new conveyor body into the existing body frame, the new conveyor body is composed of an upper frame located on the upper floor side, a lower frame located on the lower floor side, and an intermediate frame located between the upper frame and the lower frame. A method is known in which these frames are sequentially carried into the interior using an existing body frame (see Patent Document 1).

  However, in the methods described in Patent Documents 1 and 4, there is not enough space to carry in a new frame of a new conveyor main body incorporated in an existing main body frame depending on a carry-in route and a carry-in entrance in a building, and a passenger conveyor There are cases where it is not possible to renew. In particular, in the renewal of a passenger conveyor in a station such as a subway, restrictions on the carry-in space are strict (for example, the carry-in space is narrow), and it is difficult to adopt the methods of Patent Documents 1 and 4.

  Further, in the methods described in Patent Documents 2 and 3, an upper frame of a plurality of frames constituting a new conveyor main body incorporated in an existing main body frame is divided into a horizontal unit not including an inclined portion and a folding including an inclined portion. Although it is divided into two units, it is often impossible to carry these units in places where the carry-in space is limited, such as stations. In particular, a plurality of components for driving and controlling such as a driving device and a terminal gear are generally incorporated in a horizontal unit, and it is difficult to make the horizontal unit easy to carry and have a size and weight.

  The above problem is not limited to the renewal of the passenger conveyor, but may be a case where a passenger conveyor is newly installed by newly installing a main body frame and incorporating the new conveyor main body into the main body frame.

  An object of the present invention is to make it easier to carry in a passenger conveyor body.

  The passenger conveyor in this invention has a main body frame and the some component arrange | positioned inside a main body frame. The main body frame is composed of a plurality of frames that are detachably connected in the longitudinal direction. A plurality of frames are disposed between a first frame disposed on one end side in the longitudinal direction, a second frame disposed on the other end side in the longitudinal direction, and the first frame and the second frame. And one or more third frames. The first frame is composed of two or more units that are separably connected in the longitudinal direction. The two or more units include a first unit in which a driving device and a control panel are incorporated as components, and a second unit in which a terminal gear and a rail are incorporated as components. The drive device and the terminal gear in the second unit are wound in a chain.

  According to the present invention, it is possible to easily carry in the passenger conveyor body.

It is a side view which shows the structure of the passenger conveyor which concerns on embodiment. It is BB sectional drawing of FIG. It is a side view which shows the detailed structure of the upper frame of FIG. It is a figure explaining the state which isolate | separated the upper frame of FIG. 3 into the some unit. It is a side view which shows the detailed structure of the lower frame of FIG.

  Hereinafter, a passenger conveyor according to an embodiment will be described with reference to the drawings. In the following description, an escalator will be described as an example of a passenger conveyor. However, the escalator may be any passenger conveyor that circulates and moves a number of steps connected endlessly, and the passenger conveyor is not limited to an escalator. . For example, the passenger conveyor may be a moving sidewalk. In the case of a moving sidewalk, the slope is not necessary. Moreover, although the following description demonstrates the case of the renewal of a passenger conveyor as an example, the new passenger conveyor which is not renewed may be sufficient, and the existing main body frame is unnecessary in that case.

  Hereinafter, the configuration of the escalator after the renewal will be described with reference to FIGS.

  FIG. 1 is a side view of the escalator after renewal. 2 is a cross-sectional view taken along the line BB in FIG.

  In the example of illustration, the escalator after renewal shows the main body frame (existing main body frame) 1 of the escalator before renewal, and the new escalator main body installed using the existing main body frame 1. FIG. In FIG. 1, the existing main body frame 1 is indicated by a two-dot chain line, and the new main body frame 11 which is a main body frame of the new escalator main body is indicated by a solid line.

  The escalator before renewal has an existing main body frame 1, and a plurality of components are arranged on the existing main body frame 1. The components arranged in the existing main body frame 1 are, for example, a driving device such as a motor or a speed reducer, a control panel, a driving wheel (terminal gear), a terminal rail, a moving handrail, a handrail driving device, a balustrade, etc. Are also not shown in FIG. The drive device, the control panel, the drive wheel, and the like are components that are housed inside the existing main body frame 1 (hereinafter referred to as housing parts), for example. Moreover, a moving handrail, a handrail driving device, a balustrade, a step, and the like are components that are arranged, for example, inside or above the existing main body frame 1 (hereinafter referred to as arrangement components). That is, the escalator before renewal has the existing main body frame 1 and the accommodation components and the arrangement components arranged in the existing main body frame 1.

  At the time of renewal, a plurality of component parts (accommodating parts and arrangement parts) are removed leaving the existing main body frame 1, and only the existing main body frame 1 remains. In addition, although the escalator before renewal is comprised by the existing main body frame 1 and several components here, the inner main body frame and component (not shown) which are not shown as an escalator main body inside the existing main body frame 1 are accommodated. (Components and arrangement components) may be provided. In this case, at the time of renewal, the inner main body frame and the component parts (accommodating parts and arrangement parts) arranged in the existing main body frame 1 are removed, and only the existing main body frame 1 remains.

  After the renewal, as shown in FIG. 1, the new escalator main body is disposed on the existing main body frame 1. The new escalator main body is an escalator main body newly disposed in the existing main body frame 1 in place of the constituent parts that the escalator before renewal had. The new escalator main body includes a new main body frame 11 and constituent parts (accommodating parts and arrangement parts) (not shown) arranged inside (and / or the upper part) of the new main body frame 11.

  First, the existing main body frame 1 will be described.

The existing main body frame 1 is a frame having a truss structure, for example. The existing body frame 1 is located between the upper part 3 located on one end side (upper floor side), the lower part 2 located on the other end side (lower floor side), and the upper part 3 and the lower part 2. It is an integral structure composed of the intermediate portion 4. The lower part 2, the upper part 3, and the intermediate part 4 are connected in series in the longitudinal direction. A first housing space is formed inside the existing main body frame 1. The illustrated X ₁ and X ₂ are division positions of the existing main body 1. In other words, between the divided position X ₁ and the split position X ₂ is the middle section 4, below the dividing position X ₁ is a lower portion 2, above the dividing position X ₂ is the upper part 3.

  The newly installed main body frame 11 is accommodated in the first accommodating space. For this reason, the new main body frame 11 is formed smaller than the existing main body frame 1 in the longitudinal direction and the short side direction.

Please refer to FIG. The existing main body frame 1 has a pair of left and right side frames 7A and 7B, and a bottom member 8 connected to the pair of side frames 7A and 7B at the lower part. The existing main body frame 1 is formed in a substantially U-shaped cross section by the side frames 7A and 7B and the base material 8. The side frame 7A includes an upper chord member 9a, a lower chord member 9b positioned below the upper chord member 9a, and a vertical member 9c positioned between the upper chord member 9a and the lower chord member 9b. It is comprised by connecting. The side frame 7B facing the side frame 7A has the same configuration as the side frame 7A. The lower chord material 9b of the side frame 7A and the lower chord material 9b of the side frame 7B are connected to both ends of the base material 8, respectively. Thereby, the first accommodation space S1 is formed. In the first housing space S1, the length of the existing body frame 1 in the short direction is set to W ₁ and the height is set to h ₁ .

  Next, the new main body frame 11 will be described.

  The new main body frame 11 is connected to the pair of left and right side frames 15A and 15B, the bottom member 16 connected to the pair of side frames 15A and 15B at the lower part, and the side frames 15A and 15B at substantially the middle in the height direction. And a cross beam 17 to be provided.

The side frame 15A connects an upper chord member 18a, a lower chord member 18b positioned below and spaced from the upper chord member 18a, and a vertical member 18c located between the upper chord member 18a and the lower chord member 18b. It is composed by doing. The side frame 15B facing the side frame 15A has the same configuration as the side frame 15A. The lower chord material 18b of the side frame 15A and the lower chord material 18b of the side frame 15B are connected to both ends of the base material 16, respectively. Thereby, the second accommodation space S2 is formed. In the second housing space S2, new body frame 11 outside the lateral direction of the length (hereinafter, lateral outer width) W ₂ is the lateral direction of length of the inner of the existing body frame 1 (hereinafter, Yokouchi width) W It is set to be shorter than ₁ . The horizontal outer width _{W 2} is preferably not more than 1410Mm (mm). Since is made smaller the lateral outer width W ₂ than the transverse profile the width W _1, the first housing space S1 that existing body frame 1 is formed, it is possible to house the new main body frame 11.

  Returning to FIG. The new main body frame 11 is composed of a plurality of separable frames, and the plurality of frames are connected at a predetermined connection position in the longitudinal direction. Specifically, the new body frame 11 includes an upper frame 13 disposed on one end side (upper floor side) of the existing body frame 1, which is detachably connected in the longitudinal direction, and other parts inside the existing body frame 1. The lower frame 12 is disposed on the end side (lower floor side), and the intermediate frame 14 is disposed between the upper frame and the lower frame. The frames 12 to 14 are connected in series in the longitudinal direction. The upper frame 13 is accommodated in the upper portion 3 of the existing main body frame 1, the lower frame 12 is accommodated in the lower portion 2 of the existing main body frame 1, and the intermediate frame 14 is accommodated in the intermediate portion 4 of the existing main body frame 1.

  At least one of the upper frame 13 and the lower frame 12 is composed of three or more units that are separably connected in the longitudinal direction. In the illustrated example, the upper frame 13 is composed of three units 131 to 133, and the lower frame 12 is composed of two units. However, the upper frame 13 may be composed of two units and the lower frame 12 may be composed of three units, or both the upper frame 13 and the lower frame 12 may be composed of three or more units.

  Each of the upper frame 13 and the lower frame 12 includes an inclined portion that is mostly or entirely inclined and a horizontal portion that does not include the inclination. At least the horizontal part of the inclined part and the horizontal part is composed of a plurality of units. In the illustrated example, the horizontal portion of the upper frame 13 includes a first upper horizontal unit 131 and a second upper horizontal unit 132, and the inclined portion of the upper frame 13 includes an upper inclined unit 133. The horizontal portion of the lower frame 12 includes a first lower horizontal unit 121, and the inclined portion of the lower frame 12 includes a lower inclined unit 122. The units 131, 132, 133, 121, and 122 preferably have a length in the longitudinal direction of 2000 mm (millimeters) or less. The weight is desirably 1800 kg or less. In this way, by dividing the length and weight smaller than the conventional one, it is easy to carry in each unit.

  The intermediate frame 14 is configured by connecting a plurality of intermediate units in a separable manner. In the illustrated example, the intermediate frame 14 includes three intermediate units 141 to 143, but the number of intermediate units may be any number. The length of each of the intermediate units 141 to 143 (the length along the longitudinal direction) is the same as the length of any one of the first upper horizontal unit 131, the second upper horizontal unit 132, and the tilt unit 133. Or shorter than that length. The length of at least one of the units 131 to 133, desirably all, is, for example, 2000 mm (millimeters) or less.

In the illustrated example, the new main body frame 11 includes eight units 121, 122, 131, 132, 133, 141, 142, and 143, and each unit 121, 122, 131, 132, 133, 141, 142, 143 Are connected at the separation positions Y _{1 to} Y ₇ . The number of units of the escalator body (number of separation positions) may be determined based on the length in the longitudinal direction of the newly installed main body frame 11 of the escalator body. Further, the separation position and the number of units (the number of separation positions) when separating the horizontal portion into each unit are determined based on the length of the horizontal portion in the longitudinal direction. In the illustrated example, since the horizontal unit (unit not including the inclined portion) is two units 131 and 132 (0 or 1 in the past) in the upper horizontal portion, the length and weight in the longitudinal direction can be reduced. It was. In the upper horizontal portion, three or more horizontal units (units not including the inclined portion) may be used.

  FIG. 3 is a side view showing a detailed configuration of the upper frame 13.

  A plurality of components are incorporated in each of the units 131 to 133 of the upper frame 13. In the illustrated example, the first upper horizontal unit 131 includes a drive device 21 (for example, a motor or a speed reducer) and a control panel 22 as components. An upper terminal gear (upper drive wheel) 23 and an upper terminal rail 24 are incorporated in the second upper horizontal unit 132 as components. A linear rail 25 is incorporated in the upper inclined unit 133 as a component. By incorporating the components into the units 131 to 133 in this way, the weight and size of the units can be more uniformly distributed than in the past. In particular, by dividing between the heavy drive device 21 and the upper terminal gear 23, the weight of each unit can be prevented from becoming too large.

  The driving device 21 of the first upper horizontal unit 131 and the upper terminal gear 23 of the second upper horizontal unit 132 are wound in a chain so as to connect the driving device 21 and the upper terminal gear 23. Thereby, the driving force of the driving device 21 can be transmitted to the upper terminal gear 23. The chain straddles the boundary between units 131 and 132. Further, the upper terminal gear 23 of the second upper horizontal unit 132 and the straight rail 25 of the upper inclined unit 133 are connected by the curve rail 27. A handrail driving device 26 for driving the moving handrail is also incorporated. The curve rail 27 straddles the boundary between the units 132 and 133. The handrail drive device 26 is also installed so as to straddle the boundary between the units 132 and 133.

  FIG. 4 is a diagram illustrating a state where the upper frame 13 is separated into a plurality of units 131 to 133.

  In a state where the first upper horizontal unit 131 and the second upper horizontal unit 132 are separated, the chain connecting the driving device 21 and the upper terminal gear 23 is removed. Further, in the state where the second upper horizontal unit 132 and the upper inclined unit 133 are separated, the curve rail 27 and the handrail drive device 26 that connect the terminal gear 23 and the linear rail 25 are removed.

  FIG. 5 is a side view showing a detailed configuration of the lower frame 12.

  Each unit 121, 122 incorporates a plurality of components. In the illustrated example, a lower terminal gear 28 and a lower terminal rail 29 are incorporated in the first lower horizontal unit 121 as components. Moreover, the linear rail 31 is integrated in the lower inclination unit 122 as a component. The lower curve rail 30 is installed so as to straddle the boundary between the units 121 and 122.

  Moreover, a linear rail is incorporated in the intermediate units 141 to 143 as components.

  Next, an escalator renewal method will be described.

  In each unit 121, 122, 131, 132, 133, 141, 142, 143, components are incorporated in advance at a predetermined location such as a factory (before each unit is transported to the site where the escalator is installed). . At this time, after all the units 131 to 133 are once connected, the upper frame 13 is separated into the units 131 to 133 after being provided with a positioning portion serving as a positioning mark at the separation position. . The positioning unit may be any component of the units 131 to 133, or may be a member that is removed after connecting the units 131 to 133 in the field, or is a simple mark that has been renewed. Can also be left. In addition, the lower frame 12 is also connected to the units 121 and 122 after all the units 121 and 122 are once connected and then provided with a positioning portion serving as a positioning mark at the separation position. The intermediate frame 14 is also connected to the units 131 to 133 after the intermediate units 141 to 143 are once connected and a positioning portion serving as a positioning mark is provided at the separation position.

  Each unit 121, 122, 131, 132, 133, 141, 142, 143 carried in separately is connected on the site by a connecting member such as a reamer bolt. The units are connected to each other at each of the frames 12, 13 and 14 at the factory, and it is practically only necessary to connect the units at the separation position indicated by the positioning portion at the site. The work is easy. Further, as described above, since the units are connected to each other for each of the frames 12, 13 and 14 at the factory, the dimensional accuracy of each of the frames 12 to 14 is high, and the centering operation of each component on the site is performed. And fine adjustment work of each component becomes easy.

  More specifically, in the case of the upper frame 13, the chain connecting the driving device 21 and the upper terminal gear 23, the handrail driving device 26, and the curve rail 27 need to be installed locally. In the case of the lower frame 12 as well, the lower curve rail 30 needs to be installed locally. However, at the time of factory assembly, all the units 121, 122, 131, 132 and 133 constituting the upper frame 13 and the lower frame 14 are once connected, and all the components are assembled and centering is performed. Each unit 121, 122, 131, 132 and 133 is separated and delivered to the site. At the site, after the units 131, 132 and 133 of the upper frame 13 are connected, the chain is fixed so as to connect the driving device 21 and the upper terminal gear 23, and the handrail driving device 26 has a predetermined mounting position of the upper frame 13. The curved rail 27 is attached to the upper frame 13 in accordance with a terminal rail or a straight rail incorporated in each unit. For this reason, it is possible to easily perform on-site centering work and fine adjustment work of each component. Also in the lower frame 12, the curve rail 30 is attached to the lower frame 12 after connecting the units 121 and 122 of the lower frame 12 in the field. Therefore, as with the upper frame 13, it is possible to easily perform a centering operation and a fine adjustment operation of each component.

  The units 141 to 143 of the intermediate frame 14 are preinstalled with straight rails at the time of assembly at the factory, and have a length that matches the dimensions of the units 121, 122, 131, 132, and 133 of the lower frame 12 and the upper frame 13. Good.

  According to the above-described embodiment, the new main body frame 11 can be carried in even in a place where a carry-in entrance and a carry-in route are narrow and there is no sufficient carry-in space, such as in a subway station. For this reason, the renewal work for each unitized frame can be performed without increasing difficult field work.

  Further, by reducing the size of each unit and suppressing the weight of each unit, each unit can be carried in using an elevator. For this reason, it can be expected that the renewal will be greatly expanded. In particular, the horizontal portion of the upper frame 13 in which heavy components such as the drive device 21 and the terminal gear 23 are incorporated is separated into a plurality of units 131 and 132 and a plurality of components are incorporated in the horizontal portion of the upper frame 13. Are distributed in a plurality of units 131 and 132. For this reason, the transportability is improved, and the frame loading operation is facilitated.

  The embodiments described above are examples for explaining the present invention, and are not intended to limit the scope of the present invention only to those embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.

  For example, in the present embodiment, components (such as heavy components) accompanied by driving and control such as a driving device are incorporated in each unit of the upper frame 13, but these components may be incorporated in the lower frame.

Moreover, about the passenger conveyor whose length of the lower horizontal part of the existing main body frame is longer than the length of the lower horizontal part in the said embodiment, the number of units may be increased, for example. For example, when there are three units, a separation position may be added between a lower support portion (for example, a lower receiving beam portion that is a portion that supports an escalator with a beam of a building) and a lower terminal gear.
Moreover, a passenger conveyor is not restricted to an escalator. For example, the passenger conveyor may be a moving sidewalk. In the case of a moving sidewalk, the slope is not necessary.
Moreover, it may be a new passenger conveyor that is not renewed, and in that case, the existing main body frame is unnecessary.
