It is preferable that the removal step 107 is selected so that the step 107 on which the motor mounting table 100 is mounted is the step 107 closest to the position below the motor M to be removed. The configuration of the motor mounting base 100 and the installation method of the motor mounting base 100 will be described later.

Subsequently, the operator removes the motor M from the second drive unit 110. Next, the operator moves the motor M removed from the second drive unit 110 in a substantially horizontal direction and mounts it on the motor mounting table 100. Then, the operator performs replacement work such as replacing the bearing of the motor M mounted on the motor mounting table 100 or the accessory equipment of the motor. Since the procedure for attaching the motor M is a procedure for reversing the procedure for removing the motor M described above, the description thereof will be omitted.

The configuration of the motor mounting base 100 and the mounting method of the motor mounting base 100 will be described with reference to FIGS. 3 and 4. FIG. 3 is a front view showing the configuration of the motor mounting base 100. FIG. 4 is a side view showing the configuration of the motor mounting base 100.

In the following, in the state where the motor mounting base 100 is mounted in step 107, the direction parallel to the traveling direction of the intermediate type escalator 150 is the front-rear direction of the motor mounting base 100, and the upper floor side of the intermediate type escalator 150 is the front side. To do. The width direction is the direction orthogonal to the front-back direction on the horizontal plane. In the width direction, the right side is the right side when facing the front side of the motor mounting base 100. The direction orthogonal to the front-back direction and the width direction is the vertical direction.

The motor mounting base 100 mounts the motor M on step 107 of the intermediate escalator 150. The motor mounting base 100 includes a mounting portion 10, a meshing portion 20, an engaging portion 30, and a support portion 40. Details of the meshing portion 20 will be described later with reference to FIGS. 5 and 6.

The motor M of the present embodiment is formed, for example, in a substantially cylindrical shape, but is not limited thereto. A terminal block M1 and a mounting base M2 are provided on the side surface of the motor M of the present embodiment, but the present invention is not limited thereto. For example, the motor may not be provided with the terminal block M1 or the mounting base M2.

The mounting unit 10 mounts the motor M. The mounting portion 10 is formed in a substantially plate shape in a plan view. The length of the mounting portion 10 in the front-rear direction is preferably longer than the axial length (total length) of the motor M and shorter than the length in the traveling direction of step 107. It is preferable that the length of the mounting portion 10 in the width direction is sufficiently larger than the diameter of the motor M.

The engaging portion 30 engages the motor mounting base 100 with the step shaft 108 on the step 107. The engaging portion 30 is provided at the front end of the mounting portion 10 and at a substantially central portion in the width direction. The engaging portion 30 has a main body 31 and an extending portion 32.

The main body 31 is formed in a substantially plate shape in a plan view. The main body 31 is provided on the mounting portion 10 so as to extend downward at the front end of the mounting portion 10 and at a substantially central portion in the width direction. The extending portion 32 is formed in a substantially plate shape in a plan view. The extending portion 32 is provided on the main body 31 so as to extend rearward from the lower end of the main body 31. Here, the extension portion 32 is provided on the main body 31 so as to be located slightly below the step shaft 108 when the motor mounting base 100 is mounted on the step 107.

With such a configuration, when the motor mounting table 100 is installed on the step 107, the rear end surface of the main body 31 of the engaging portion 30 and the front end surface of the step 107 come into contact with each other, so that the motor mounting table 100 comes into contact with the motor mounting table. The backward movement of 100 is restricted. Further, when the motor mounting base 100 is about to be lifted from above step 107, the extending portion 32 of the engaging portion 30 engages with the step shaft 108, so that the motor mounting base 100 is lifted from above step 107. It cannot be lifted.

When removing the motor mounting base 100 installed on the step 107, the motor mounting base 100 is moved forward on the step 107 until the extending portion 32 of the engaging portion 30 does not engage with the step shaft 108. Then remove the motor mounting base 100.

In the present embodiment, the extension portion 32 is provided on the main body 31 so as to be located slightly below the lower end of the step shaft 108, but the extension portion 32 is located slightly above the step shaft 108. The configuration may be provided on the main body 31 as described above.

The support portion 40 supports the motor M mounted on the mounting portion 10. The support portion 40 has a pair of wall portions 41, 41 and a pair of contact portions 42, 42. The pair of wall portions 41, 41 are provided on the mounting portion 10 along the front-rear direction and on the right end side and the left end side in the width direction. Here, the motor M is mounted on the motor mounting table 100 so that the axial direction of the motor M and the front-rear direction of the motor mounting table 100 are parallel to each other in the gap between the pair of wall portions 41, 41. The distance between the pair of wall portions 41, 41 is preferably such that when the motor M is mounted in the gap between the pair of wall portions 41, 41, a slight gap is provided between the lower end of the motor M and the mounting portion 10. ..

The wall portion 41 is formed in a substantially triangular shape when viewed from the front-rear direction. The height of the wall portion 41 is not particularly limited, but it is preferably substantially the same as the radius of the motor M. A contact portion 42 is provided inside the wall portion 41 in the width direction. The contact portion 42 is made of rubber as an elastic member, for example, but is not limited thereto.

With such a configuration, when the motor M is mounted on the motor mounting base 100, the motor M is a V-shaped groove formed as a gap between a pair of wall portions 41, 41 of the support portion 40. It is sandwiched between and supported. At this time, since the motor M is supported in contact with the pair of contact portions 42, 42, it is firmly supported by the motor mounting base 100.

The configuration of the meshing portion 20 will be described with reference to FIGS. 5 and 6. FIG. 5 is a bottom view showing the configuration of the meshing portion 20. FIG. 6 is a cross-sectional view showing the MM cross section of FIG.

The meshing portion 20 is provided on the bottom surface of the mounting portion 10. The meshing portion 20 meshes with the cleat groove 107A of step 107 when the motor mounting base 100 is installed in step 107. The meshing portion 20 is made of rubber as an elastic member, for example, but is not limited thereto.

The meshing portions 20 are provided at the four corners of the bottom surface of the mounting portion 10, for example, in a plan view, but are not limited thereto. The meshing portion 20 may be provided on the entire surface of the bottom surface of the mounting portion 10, or may be provided on the front end portion and the rear end portion of the bottom surface of the mounting portion 10.

The meshing portion 20 has a wedge shape. The wedge shape is formed along the anteroposterior direction. The meshing portion 20 is formed in a wedge shape when viewed from the front-rear direction. Specifically, the wedge shape is a shape in which the thickness in the width direction decreases from the base end side to the tip end side. In other words, the meshing portion 20 has grooves formed between the wedge shapes. The groove portion is formed along the front-rear direction, and is formed in a substantially V shape when viewed from the front-rear direction.

The meshing portion 20 is inserted into the cleat groove 107A of step 107 when the motor mounting base 100 is installed on step 107. The wedge shape is formed so that the distance between the wedge shapes is substantially the same as the distance between the cleat grooves 107A.

Here, the width b of the cleat groove 107A in step 107, the width a of the wedge-shaped tip portion, and the width c of the base end portion are defined. At this time, the wedge shape is formed so that the magnitude relation between the width a, the width b, and the width c is width a <width b <width c. In other words, in the wedge shape, the width of the base end portion is larger than the width of the cleat groove 107A in step 107, and the width of the tip portion is smaller than the distance between the cleat grooves 107A in step 107.

Further, the cleat groove 107A in step 107 is set to the depth e. On the other hand, the height d is defined as the wedge-shaped base end to the tip end. At this time, the wedge shape is formed so that the magnitude relationship between the depth e and the height d is height d <depth e. In other words, the height from the wedge-shaped base end to the tip end is smaller than the depth of the cleat groove 107A in step 107.

With such a configuration, the width a of the wedge-shaped tip portion is smaller than the width b of the cleat groove 107A. Therefore, when the motor mounting base 100 is installed on the step 107, the meshing portion 20 is set to the cleat groove 107A. Can be easily plugged into. Further, since the width c of the wedge-shaped base end portion is larger than the width b of the cleat groove 107A, if the motor mounting base 100 is pressed onto the step 107, the meshing portion 20 is firmly sandwiched by the cleat groove 107A. .. As a result, a large frictional force is generated between the meshing portion 20 and the cleat groove 107A, and the motor mounting base 100 does not move in the width direction and the front-rear direction.

Further, since the height d of the wedge shape is smaller than the depth e of the cleat groove 107A, when the motor mounting base 100 is installed on the step 107, the convex portion of the cleat groove 107A is surely reached to the base end portion of the wedge shape. Is reached, and the meshing portion 20 is firmly sandwiched in the cleat groove 107A.

The effect of the motor mounting base 100 will be described. According to the motor mounting table 100, the motor M can be stably mounted on step 107 of the intermediate escalator 150.

The configuration of the motor mounting table 200 of another embodiment and the mounting method of the motor M will be described with reference to FIG. 7. FIG. 7 is a front view showing the configuration of the motor mounting base 200.

The motor mounting base 200 mounts the motor M on step 107 of the intermediate escalator 150. The motor mounting base 200 includes a mounting portion 10, a meshing portion 20, and an engaging portion 30. Since the mounting portion 10, the meshing portion 20, and the engaging portion 30 have been described above, description thereof will be omitted.

In the motor mounting base 200, the mounting base M2 of the motor M is mounted on the mounting portion 10 as it is, so that the motor M is mounted on the motor mounting base 100. In this way, even the motor mounting base 200 in which the support portion 40 is omitted can achieve substantially the same effect as the motor mounting base 100 of the present embodiment.

In addition, as a motor mounting table of another embodiment, a motor mounting table in which the engaging portion 30 is omitted may be used. Even in this case, the same effect as that of the motor mounting table 100 of the present embodiment can be obtained. It should be noted that the present invention is not limited to the above-described embodiments and modifications thereof, and it goes without saying that various changes and improvements can be made within the scope of the matters described in the claims of the present application. ..
