Description

  The present invention relates to a passenger conveyor, for example, a guide rail bracket that supports a step guide rail in the passenger conveyor.

  Passenger conveyors such as escalators and electric roads are known. A passenger conveyor generally includes a step, a guide rail for the step, a guide rail bracket, and a frame of the passenger conveyor. The guide rail is attached to the frame of the passenger conveyor by a guide rail bracket.

  The guide rail mounting work sequence is as follows. First, the frame of the passenger conveyor is manufactured, then the guide rail bracket is attached to the frame, and finally the guide rail is attached to the guide rail bracket.

  The mounting accuracy of the guide rail is closely related to the riding comfort of the traveling step and the generated noise. For this reason, the guide rail is required to have high mounting accuracy in the width direction and the height direction with respect to the passenger conveyor.

  In the installation work of the guide rail, the divided guide rails constituting the passenger conveyor inclined portion are placed on the guide rail bracket in order from the lower side to the upper side of the passenger conveyor and temporarily fixed by bolts. Next, the dimensions are confirmed, and the bolt is finally tightened to the proper position. As a result, the guide rail mounting operation is completed.

  This work has been devised to improve workability, for example, by using a special facility for assembling to make the angle of the inclined portion loose. However, in order to ensure a horizontal angle during assembly work, large-scale equipment is required. On the other hand, if the equipment is not used, the work environment is not good. Also, when performing guide rail installation work on site, it is difficult to change the inclination angle during the work.

  The mounting accuracy of the guide rail greatly affects the riding comfort of the passenger conveyor as described above. For example, the techniques disclosed in Patent Documents 1 and 2 are known as techniques relating to improvement of guide rail mounting accuracy.

  The guide rail is attached to the frame of the passenger conveyor by a guide rail bracket. The work for mounting the guide rail to the guide rail bracket is required to be highly accurate, but if it is simply required to be highly accurate, a difficult mounting work is required. In addition, the installation work is not always performed on a horizontal scaffold.

  An object of the present invention is to improve the ease of attaching the guide rail to the guide rail bracket.

  Even if the guide rail on which the step travels is not fixed to the guide rail bracket by the fixing member, there is provided a limiting member that limits the range in which the guide rail can move on the guide rail bracket. The limiting member is provided, for example, on the inner side along the width direction of the passenger conveyor from the place where the guide rail is fixed on the mounting surface of the guide rail bracket (the surface on which the guide rail is mounted and fixed by the fixing member). Protrusion or wall.

  “The guide rail is not fixed to the guide rail bracket by the fixing member” means that the guide rail is not completely fixed to the guide rail bracket, for example, the guide rail has N fixing members (N is 2). In the state where the guide rail is only attached with less than N fixing members, or the guide rail is mounted on the guide rail bracket, but the fixing member is used. It may include no state.

  The ease of attaching the guide rail to the guide rail bracket can be improved.

It is a front view of the guide rail and guide rail bracket of the step in the passenger conveyor concerning an embodiment. It is a side view of the guide rail and guide rail bracket of the step in the passenger conveyor concerning an embodiment. It is a general view of a passenger conveyor concerning an embodiment.

  Hereinafter, an embodiment will be described with reference to the drawings.

  Drawing 1 is a front view of a guide rail and a guide rail bracket which a passenger conveyor concerning an embodiment has. FIG. 2 is a side view of the guide rail and the guide rail bracket. FIG. 3 is an overall view of the passenger conveyor according to the embodiment. The passenger conveyor which concerns on this embodiment is an escalator, for example. In FIG. 3, 5 is a step, 6 is a handrail, 7 is a balustrade, and 8 is a frame.

  A guide rail bracket (hereinafter referred to as a bracket) 1 has a mounting surface on which the guide rail 4 is mounted. The guide rail 4 is placed on the placement surface, and the guide rail 4 is fixed to the bracket 1 by the bolt 3.

  The bracket 1 is a member (for example, a wall or a protrusion) that faces the back surface of the guide rail 4 when the guide rail 4 is placed, and the wall may be formed by bending a plate constituting the bracket 1. The cut end surface of the plate constituting the bracket 1 is also included in the wall here. For this reason, it is restrict | limited that the mounted guide rail 4 moves to an outer side along the width direction of a passenger conveyor.

  The bracket 1 includes a temporary assembly misalignment stop (limit member) 2. The temporary assembly misalignment stopper 2 is disposed, for example, in an inner (center side) direction along the width direction of the passenger conveyor than a portion where the guide rail 4 is fixed on the mounting surface of the bracket 1. Specifically, for example, the temporary assembly misalignment stopper 2 is disposed on an extension line of the mounting surface of the bracket 1 (the surface where the bottom surface of the guide rail 4 and the bracket 1 are in contact), and the back surface of the guide rail 4 (passenger conveyor) Of the guide rail 4 and the adjustment amount (allowable margin) of the guide rail 4 are arranged at a position away from the surface facing the bracket 1 and the surface facing the bracket 1. Is done.

  Specifically, for example, the temporary assembly misalignment stopper 2 is a member extending upward from the mounting surface, and specifically, a wall or a protrusion. As a wall, you may bend and form the board which comprises the bracket 1, and the cut end surface of the board which comprises the bracket 1 is also contained in the wall here.

  The following first and second effects can be expected from the temporary assembly misalignment stopper 2.

  <First effect>.

  The guide rail 4 of the step 5 in the passenger conveyor is attached to the frame 8 of the passenger conveyor by the bracket 1. As a work sequence, first, the frame 8 of the passenger conveyor is manufactured, then the bracket 1 is attached to the frame 8, and finally the guide rail 4 is attached to the bracket 1. The accuracy of mounting the guide rail 4 to the bracket 1 is closely related to the riding comfort of the traveling step 5 and the generated noise. For this reason, the guide rail 4 is required to have high mounting accuracy in the width direction and the height direction with respect to the passenger conveyor.

  In the installation work of the guide rail 4, the divided guide rails 4 constituting the passenger conveyor inclined portion are placed on the bracket 1 in order from the lower side to the upper side of the passenger conveyor and temporarily fixed with the bolts 3. Next, the dimensions are confirmed, and the bolt 3 is finally tightened to a proper position. Thereby, the installation work of the guide rail 4 is completed.

  This work can be expected to improve the ease of work, for example, by using a special facility for assembling and by making the angle of the inclined portion gentle.

  However, in order to ensure a horizontal angle during assembly work, large-scale equipment is required. On the other hand, if the equipment is not used, the work environment is not good. In addition, when the work for attaching the guide rail 4 is performed on site, it is difficult to change the inclination angle during the work, and the work environment becomes more severe.

  The temporary assembly misalignment stop 2 described above prevents the guide rail 4 from being displaced on the bracket 1 without any limitation when the guide rail 4 is temporarily assembled (temporary fixing and position adjustment). For this reason, the ease of work improves. The temporary assembly misalignment stopper 2 limits the range in which the guide rail 4 can move on the bracket 1 even if the guide rail 4 placed on the bracket 1 is not even temporarily fixed to the bracket 1 by the bolt 3. Can do.

  <Second effect>.

  Furthermore, the temporary assembly misalignment stopper 2 can also prevent the guide rail 4 from dropping from the bracket 1.

  Bolts 3 are used to fix the guide rail 4 to the bracket 1. As the bolt 3, various types of bolts can be used. In this embodiment, a bolt having a rectangular bolt head shape (for example, a so-called T bolt) is used. The length of the short side of the head of the bolt 3 is shorter than the width of the opening provided in the bottom surface of the guide rail 4 (the opening into which the bolt 3 is inserted), and the length of the long side of the head of the bolt 3 is The width of the opening of the bottom surface of the guide rail 4 is longer. In the bolt 3 fastening operation, the bolt 3 is inserted into the opening of the guide rail 4 so that the short side of the head of the bolt 3 is aligned with the opening of the bottom of the guide rail 4, and then the head of the bolt 3 is rotated and fastened. Done. In a state before fastening (that is, at the stage of temporary fixing), depending on the direction of the head of the bolt 3, the bolt 3 may drop from the opening on the bottom surface of the guide rail 4. The temporary assembly misalignment stopper 2 is limited in the range in which the guide rail 4 moves (for example, the range of movement in the width direction or the angle of rotation about a certain position) even when the bolt 3 has fallen off. Therefore, the guide rail 4 can be prevented from dropping from the bracket 1.

  The above is the first and second effects of the temporary assembly misalignment stopper 2.

  The bracket 1 is formed, for example, by processing a member cut out from a predetermined member (for example, a steel plate) (for example, bending a plate material). The temporary assembly misalignment stopper 2 may be formed integrally with the bracket 1. For this reason, in order to form the temporary assembly misalignment stopper 2, it is only necessary to change the cutting shape of the predetermined member, and the dimensional accuracy is hardly required. Further, the temporary assembly misalignment stop 2 is sufficiently smaller than the size of the bracket 1 itself, and the cost required to add the temporary assembly misalignment stop 2 is almost zero.

  Although one embodiment has been described above, the present invention is not limited to the above embodiment. For example, the present invention can be applied to a passenger conveyor of a type other than an escalator, such as an electric road.

  Further, for example, the temporary assembly misalignment stop 2 may be a component independent of the bracket 1, or the temporary assembly misalignment stop 2 may be provided on the guide rail 4 instead of the bracket 1. And a combination of members provided on both of the guide rails 4. For example, the mounting surface of the bracket 1 is provided with an opening (for example, a hole or a slit), and the guide rail 4 is provided with a member extending downward from the bottom surface. The movement of the placed guide rail 4 may be restricted by fitting in the opening of the surface. The size of the opening and / or the member extending below the guide rail 4 may not be precise. This is because the guide rail 4 is fixed to the bracket 1 by the bolt 3.

  Further, in a frame (not shown) constituting the passenger conveyor, a protrusion, a part, or the like may be provided as a temporary assembly misalignment stop 2 on the frame near the guide rail 4.
