Description

  The present invention relates to an escalator support device that supports a body frame of an escalator.

  FIG. 3 is a diagram showing a configuration of a conventional escalator support device.

  Conventionally, the escalator has a main body placed on the receiving beam on the building side, and support for adjusting the height (centering) so that the floor surface of the building and the floor surface of the escalator are the same height. A device is provided. As one of the prior arts of this type of support device, for example, as shown in FIG. 3, a support portion 21 made of L-shaped steel or the like provided on the frame 30 at the end of the main body frame of the escalator, and the receiving beam portion 6 on the building side. 2. Description of the Related Art An escalator board installation device that includes a base 20 provided on the base 20 and a jack bolt 3 that can arbitrarily adjust the holding height of the base 20 on the base 20 itself is known (see, for example, Patent Document 1). .

  In this prior art escalator board installation device, the support portion 21 at the end of the escalator body frame is placed on the receiving beam portion 6 on the building side, and the holding height of the base 20 is adjusted by the jack bolt 3 provided on the support portion 21. By doing so, centering is performed so that the floor surface of the building and the floor surface of the escalator are the same.

  However, since the escalator board installation device of the prior art supports the entire load of the escalator only with the tip of the jack bolt 3, the jack bolt is used when a strong vibration such as an earthquake occurs on the building or the escalator. When the escalator moves from its normal position due to insufficient frictional force between the tip 3 of the building 3 and the receiving beam 6 on the building side, the jack bolt 3 falls off the receiving beam 6 on the building side and cannot be restored. In the worst case, there was an accident in which the support portion 21 of the escalator falls off the receiving beam portion 6 on the building side. Further, when the tip end portion of the jack bolt 3 and the receiving beam portion 6 on the building side are engaged or bonded, an excessive force is applied to the jack bolt 3 body, and the jack bolt 3 body may be bent. It was.

  Therefore, in order to prevent such a situation from occurring, a liner made of a steel plate or the like is inserted into the gap between the support portion 21 and the receiving beam portion 6 on the building side to fill the gap, and the support portion 21 and the liner The fixing strength increasing operation for securing the bonding strength between the support portion 21 and the receiving beam portion 6 is performed by welding the like.

  In addition to the fixing strength increasing operation, as one of the prior arts for preventing the above-described situation from occurring, although not shown, a base 20 that can be adjusted in the height direction below the support portion 21. And a support device for a passenger conveyor, which includes a liner and a vibration isolating rubber interposed between the support portion 21 and the base 20, and fastens the base 20 and the liner and the anti vibration isolator together in advance. Has also been proposed (see, for example, Patent Document 2).

  However, after using the prior art escalator substrate installation apparatus disclosed in Patent Document 1, a liner or the like is inserted into the gap between the support portion 21 and the receiving beam portion 6 on the building side to fill the gap, thereby supporting the portion 21. Even when the fixing strength increasing operation for welding the liner or the like is performed, it is necessary to prepare liners or the like of various thicknesses in advance, and this preparation operation is complicated. Moreover, since the space | interval of the support part 21 and the receiving beam part 6 by the side of a building is narrow in many cases, it is a problem that workability | operativity at the time of insertion of a liner etc. or welding is bad.

  Further, in the conventional passenger conveyor support device disclosed in Patent Document 2, although the base 20 and the liner or the vibration-proof rubber are structured in advance under the support portion 21, the total load of the escalator is obtained. Since the structure is supported only by the tip of the jack bolt 3, the tip and the base of the jack bolt 3 and the base in the event of a disaster in which strong vibration such as an earthquake acts on the building or escalator occurs. There is a possibility that the fixing force with 20 is insufficient. That is, there is a concern that the bonding strength between the support portion 21 and the receiving beam portion 6 cannot be sufficiently secured.

  The present invention was made from the actual situation of the prior art, and its purpose is to support an escalator that is excellent in workability and can sufficiently secure the bonding strength between the support portion and the receiving beam portion on the building side. To provide an apparatus.

  In order to achieve the above object, an escalator support device of the present invention includes a support portion that is provided at an end portion of a main body frame of the escalator and supports the end portion of the main body frame, and this support portion is a receiving beam on the building side. In the support device for the escalator disposed in the portion, a base provided in the beam receiving portion, a jack bolt for adjusting a height of the support portion from the base, and provided in the base, the support portion And a protruding portion to be inserted.

  According to the support device for an escalator of the present invention, the workability is excellent, and the bonding strength between the support portion and the receiving beam portion on the building side can be sufficiently ensured.

Here, the building-side receiving beam portion 6 is made of, for example, a concrete structure, and the fixed portion is, for example, an anchor bolt (not shown) that fixes the extending portion 1b of the base 1 and the building-side receiving beam portion 6 to each other. ) And an anchor bolt fixing hole 12 through which the anchor bolt is inserted.

  Furthermore, the first embodiment of the present invention includes a departure prevention unit that prevents the support unit 5 from deviating from each pin 2. For example, a male screw (not shown) formed on each pin 2 and a female screw that is screwed with the male screw are formed in the deviation preventing portion, and the horizontal piece 5b of the support portion 5 is inserted into each pin 2. And a fixing nut 4 attached to the pin 2 from above.

  Next, the centering operation for adjusting the height of the floor top surface of the frame 30 at the end of the escalator body frame and the floor finish surface of the building using the first embodiment of the escalator support device according to the present invention will be described. To do. In the following description, it is assumed that the escalator support device according to the first embodiment of the present invention is attached to the escalator support 5 in advance and shipped.

  In the first embodiment of the present invention, an operator who performs a centering operation first lifts the entire escalator with a hoist or the like, and the portion of the support device according to the first embodiment of the present invention is placed on the receiving beam portion 6 on the building side. To be installed. That is, the base 1 integrated with the frame 5 and the respective pins 2, the jack bolts 3, the fixing nuts 4, and the nuts 7 is disposed on the installation portion of the receiving beam portion 6. At this time, the jack bolt 3 and the fixing nut 4 are assembled so that the base 1 and the horizontal piece 5b of the support portion 5 are in close contact with each other or separated with a gap of about several millimeters open.

  Next, the jack bolt 3 is rotated so that the floor top surface of the frame 30 at the end of the main frame of the escalator and the floor finish surface of the building are aligned on the same surface, and the base 5 of the horizontal piece 5b of the support portion 5 By adjusting the height, the frame 30 at the end of the main frame of the escalator is moved up and down to center the frame 30 in the height direction.

  At this time, four pins 2 projecting upward from the base 1 are inserted into the four through holes that are spaced apart in the four directions of the support portion 5, respectively, so the first embodiment of the present invention. Then, it is not necessary to insert a liner or the like into the gap between the receiving beam portion 6 on the building side and the horizontal piece 5b of the support portion 5 to fill the gap and weld the inserted liner or the like to increase the fixing strength.

  Next, in the same manner as the above-described centering in the height direction, the jack bolt 3 is rotated to finely adjust the height from the base 1 of the horizontal piece 5b of the support portion 5 to thereby adjust the body frame end of the escalator. The horizontal frame 30 is centered by moving the frame 30 up and down.

  At this time, by rotating the jack bolt 3 with respect to the nut 7 minutely, the frame 30 at the end of the main frame of the escalator can be slightly moved up and down, and precise leveling adjustment is performed. In this way, the centering work is performed in the height direction and the horizontal direction for the frame 30 at the end of the main body frame of the escalator according to the first embodiment of the present invention.

  Next, after the centering operation is performed, a fixing operation for fixing the base 1 according to the first embodiment of the present invention on the receiving beam portion 6 on the building side will be described.

  In 1st Embodiment of this invention, since the receiving-side beam part 6 by the side of a building is a concrete structure, an operator prepares an anchor bolt. Next, the operator forms a space in which the prepared anchor bolt is formed above the extending portion 1b of the base 1, that is, a space between the front end of the horizontal portion 5b of the support portion 5 and the receiving beam portion 6 on the building side.

Since it is possible to achieve both a function to increase the strength, even if a strong earthquake such as an earthquake acts on the building or escalator, the installation position of the escalator may be shifted or fallen. In addition, in the event that distortion occurs on the building side, the centering operation can be performed again. Thereby, it is excellent in workability | operativity and can fully ensure the joint strength of the support part 5 and the receiving beam part 6 by the side of a building. Therefore, 1st Embodiment of this invention can provide simultaneously the improvement of the effectiveness including centering operation | work, and the joint strength at the time of installation of an escalator, and reinforcement | strengthening of product itself.

  Further, in the first embodiment of the present invention, the end on the building side (the end on the side opposite to the end on the escalator side) of the end of the base 1 extends to the building side rather than the tip of the support 5. Since the extended portion 1b of the base 1 does not face the horizontal piece 5b of the support portion 5, the upper portion of the extended portion 1b is opened so that the base 1 can be fixed or the jack bolt 3 can be replaced. A working space can be formed. Therefore, since the worker can work effectively using this work space, high convenience can be ensured.

  Further, in the first embodiment of the present invention, the anchor bolt is inserted into the anchor bolt fixing hole 12 of the extending portion 1b of the base 1 and buried therein, thereby fixing the base 1 to the receiving beam portion 6 on the building side. Therefore, the joint strength between the support portion 5 and the receiving beam portion 6 on the building side can be reinforced by the anchor bolt. Thereby, the stable fixed state with respect to the building of an escalator is realizable. Furthermore, in the first embodiment of the present invention, the worker can easily perform the anchor bolt placing and fastening work from the work space, thereby reducing the labor required for the work of fixing the base 1 of the worker. Can do.

  In the first embodiment of the present invention, the fixing nut 4 is screwed onto the pin 2 from above in a state where each pin 2 provided on the base 1 is inserted into the through hole of the horizontal piece 5b of the support portion 5. Since the support portion 5 is prevented from deviating from each pin 2, even if a vertical force is applied to the frame 30 at the end of the escalator body frame and the frame 30 jumps up, it is supported. The support 5 and the base 1 can be firmly and integrally fixed without the part 5 being pressed by the fixing nut 4 and coming off from the pin 2.

  In the first embodiment of the present invention, since the four pins 2 are arranged around the jack bolt 3, a horizontal force is temporarily applied to the frame 30 at the end of the main frame of the escalator. Even when the load is distributed to each pin 2, the load is not excessively applied to only one of the four pins 2. Thereby, since damage to each pin 2 itself can be suppressed, the frequency of replacement work of the pin 2 and the base 1 can be reduced.
