Detailed Description
Embodiment mode 1
Fig. 1 is a front view showing an elevator rope guide device according to embodiment 1 of the present invention, fig. 2 is a plan view showing the elevator rope guide device of fig. 1, and fig. 3 is a cross-sectional view taken along line III-III of fig. 1. The elevator rope guide device 1 according to embodiment 1 of the present invention is used in a rope winding operation for erecting a rope 2 of an elevator having a rope winding ratio of 2: 1. In this example, an elevator rope guide device 1 used in a rope winding operation in which a rope 2 is installed on a sheave of a counterweight will be described.
The elevator rope guide device 1 includes: a guide device 101 that is guided by a pair of guide rails 4 provided along a hoistway 3; and a wheel device 102 provided to the guide device 101.
The guide device 101 includes: a pair of guide portions 103 that are guided by the pair of guide rails 4, respectively; and a main beam 104 that is provided across the pair of guide portions 103 and supports the wheel device 102.
Each guide portion 103 has: a plurality of roller devices 106 including a pair of rollers 105 that sandwich the guide rail 4 in the width direction and roll on the width direction surface of the guide rail 4; a foreign matter removing unit 107 provided in contact with the outer peripheral surface of the roller 105 to remove foreign matter adhering to the roller 105 rolling on the guide rail 4; and a guide support 108 supported by the main beam 104 and supporting the roller device 106 and the foreign matter removal unit 107. The roller arrangement 106 also comprises rollers that roll on the top surface of the guide rail 4. In this example, each guide 103 has two roller devices 106. The two roller devices 106 of the guide section 103 are arranged apart in the longitudinal direction of the guide rail 4.
Each guide 103 has a magnet not shown. Each guide 103 is attracted to the guide rail 4 made of iron by the magnetic force of the magnet.
The main beams 104 are arranged offset in the horizontal direction, i.e., in the vertical direction perpendicular to the direction in which the pair of guide rails 4 face each other, with respect to the region in which the pair of guide rails 4 face each other, so as not to overlap the already-installed ropes, i.e., the already-installed ropes, in the height direction.
The main beam 104 has: a pair of guide-side beam portions 109 connected to the respective guide portions 103; a wheel-side beam portion 110 provided across the pair of guide-side beam portions 109; a plurality of bolts 111 provided across the guide-side beam portion 109 and the wheel-side beam portion 110; and a plurality of nuts 112 engaged with the respective bolts 111. The pair of guide-side beam portions 109 and the wheel-side beam portion 110 are arranged such that the longitudinal directions thereof are the same direction. When the pair of guide portions 103 are guided by the pair of guide rails 4, the longitudinal direction of the guide-side beam portion 109 and the wheel-side beam portion 110 is the same direction as the direction in which the pair of guide rails 4 face each other.
One guide-side beam portion 109 of the pair of guide-side beam portions 109 is formed with an elongated hole 113 extending in the longitudinal direction of the guide-side beam portion 109. The bolt 111 is inserted into the long hole 113. By fixing the guide-side beam section 109 and the wheel-side beam section 110 by the bolt 111 and the nut 112, the sliding of the guide-side beam section 109 with respect to the wheel-side beam section 110 is regulated. On the other hand, by releasing the fixation of the guide-side beam section 109 and the wheel-side beam section 110 by the bolt 111 and the nut 112, the guide-side beam section 109 can slide with respect to the wheel-side beam section 110.
A plurality of circular holes 114 are formed in the other guide-side beam portion 109 of the pair of guide-side beam portions 109. The circular holes 114 are arranged at intervals in the longitudinal direction of the guide-side beam portion 109. The bolt 111 is inserted into the circular hole 114. By changing the round hole 114 into which the bolt 111 is inserted, the position of the guide-side beam section 109 with respect to the wheel-side beam section 110 changes. In addition, the elongated hole 113 may be formed in the other guide-side beam member 109 of the pair of guide-side beam members 109, instead of the circular hole 114. In this case, the guide-side beam section 109 and the wheel-side beam section 110 are released from the fixation by the bolt 111 and the nut 112, and the guide-side beam section 109 can slide relative to the wheel-side beam section 110.
By changing the position of the pair of guide-side beam portions 109 with respect to the wheel-side beam portion 110, the main beam 104 expands and contracts, and the dimension between the pair of guide portions 103 changes.
The wheel device 102 includes: a wheel 115 on which the U-shaped portion 21 of the rope 2 is wound from below during a rope winding operation; a wheel center shaft 116 that supports the wheel 115 and extends in a direction along a horizontal plane; a wheel support 117 that supports the wheel 115 via the wheel center shaft 116; and a rotation support portion 118 provided to the wheel-side beam portion 110 and rotatably supporting the wheel support portion 117.
The wheel support portion 117 has a pair of plate portions 119 facing each other. The wheel center shaft 116 is disposed across the pair of plate portions 119.
The rotation support portion 118 supports the wheel support portion 117 rotatably such that the wheel center axis 116 is displaced between a vertical position extending in a vertical direction perpendicular to a direction in which the pair of guide rails 4 are opposed to each other and an inclined position intersecting with a vertical direction perpendicular to the direction in which the pair of guide rails 4 are opposed to each other.
Fig. 4 is a view showing a state in which the wheel center shaft 116 of fig. 2 is displaced, and fig. 5 is a sectional view viewed along a V-V line of fig. 4. As the wheel support 117 rotates, the lower end of the wheel support 117 abuts the wheel side rail portion 110 of the main rail 104. Since the lower end of the wheel support 117 abuts against the main beam 104, the range of rotation of the wheel support 117 is limited. The main beam 104 serves as a rotation restricting portion that restricts the rotation range of the wheel supporting portion 117.
As shown in fig. 3, the elevator rope guide device 1 includes a rotation regulating portion 120 provided across the guide device 101 and the pulley device 102. The rotation regulating portion 120 is formed in a pin shape. The rotation regulating portion 120 may be provided so as to straddle the wheel-side beam portion 110 of the guide device 101 and the wheel support portion 117 of the wheel device 102 when the position of the wheel center axis 116 is the vertical position. When the rotation regulating portion 120 is provided across the wheel-side beam portion 110 and the wheel support portion 117, the rotation of the rotation support portion 118 is regulated. Thereby, the position of the wheel center axle 116 is maintained in a vertical position. The wheel 115 can rotate around a wheel center axis 116.
As shown in fig. 1, the elevator rope guide device 1 further includes: a rope cover 121 provided to the wheel 115 to restrict the U-shaped portion 21 of the rope 2 wound around the wheel 115 from moving downward away from the wheel 115; a protective cover 122 provided below the guide device 101; and a pair of light emitting devices 123 arranged to sandwich the wheel 115 in a radial direction when viewed from above.
The protective cover 122 suppresses transmission of an impact to the guide device 101 and the wheel device 102 when the guide device 101 falls and the elevator rope guide device 1 collides with a member set below the elevator rope guide device 1. When the protection cover 122 is placed on the temporary placement surface, the protection cover 122 supports the guide device 101.
As shown in fig. 3, the wheel device 102 further includes: a hinge 124 provided across one of the pair of plate portions 119 and the wheel-side beam portion 110; a bolt 125 provided above the hinge 124 and extending over one of the pair of plate portions 119 and the wheel-side beam portion 110; and a nut 126 engaged with the bolt 125.
Fig. 6 is a diagram showing a state in which the plate portion of fig. 3 is displaced. The one plate 119 pivots about the hinge 124, and is displaced between an attachment position where it is attached to the wheel center shaft 116 and a release position where it is spaced apart from the wheel center shaft 116. In the case where the position of the one plate portion 119 is the mounting position, the one plate portion 119 and the other plate portion 119 together support the wheel center shaft 116. In the case where the position of one plate portion 119 is the release position, the U-shaped portion 21 of the rope 2 can be detached from the wheel 115. The cable cover 121 is displaced together with one plate portion 119.
As shown in fig. 3, when the position of the one plate portion 119 is the mounting position, the bolt 125 can be disposed so as to straddle the one plate portion 119 of the pair of plate portions 119 and the wheel-side beam portion 110. The position of one plate portion 119 is maintained in the mounting position by fitting the nut 126 with the bolt 125.
Next, a procedure of performing a rope winding operation using the elevator rope guide device 1 will be described. Fig. 7 is a diagram showing a case where a rope winding operation is performed using the elevator rope guide device 1 of fig. 1. First, the elevator rope guide device 1 is disposed at the upper part of the hoistway 3, and the operator who gets on the upper part of the car 5 winds the U-shaped portion 21 of the rope 2 from below onto the wheel 115 and attaches the rope cover 121 to the wheel 115.
Then, the fixing of the guide-side beam portion 109 and the wheel-side beam portion 110 by the bolt 111 and the nut 112 is released, and the main beam 104 is expanded and contracted, so that the guide portion 103 is brought into contact with the guide rail 4. At this time, the guide-side beam section 109 formed with the circular hole 114 slides largely with respect to the wheel-side beam section 110 in accordance with the size of the adjacent circular hole 114. The guide-side beam section 109 formed with the elongated hole 113 slides with respect to the wheel-side beam section 110 to finely adjust the length of the main beam 104.
Then, the rope 2 is fed from the drum 6, and the elevator rope guide device 1 is suspended along the guide rail 4. At this time, the operator who gets on the upper part of the car 5 visually observes the light emitted from the light emitting device 123, and sends the rope 2 out of the drum 6 while confirming the position of the elevator rope guide device 1 in the height direction.
When the elevator rope guide 1 hangs down, foreign matter adhering to the roller 105 is removed from the roller 105 by the foreign matter removing portion 107. Therefore, the elevator rope guide 1 hangs down smoothly.
When the elevator rope guide apparatus 1 reaches a destination position in the hoistway 3, an operator who gets on the upper portion of the car 5 stops sending out the rope 2 from the drum 6. Then, the operator who gets on the scaffold 7 provided in the pit removes the rotation regulating portion 120. Thereby, when the rope 2 is twisted, the wheel support 117 is rotated about the rotation support 118, so that the wheel center shaft 116 is displaced from the vertical position to the inclined position. The wheel 115 rotates with the rotation of the wheel support 117. The rotation of the wheel support 117 is restricted by the lower end of the wheel support 117 abutting against the main beam 104.
The operator boarding the upper part of the car 5 rotates the rope shackle 22, which is the end of the rope 2, in a direction to eliminate twisting of the rope 2. By eliminating the twist of the rope 2, the wheel support 117 is rotated centering on the rotation support 118, so that the wheel center shaft 116 is displaced from the inclined position to the vertical position, and the wheel 115 is returned to the original position. At this time, the worker who gets on the upper portion of the car 5 confirms that the wheels 115 are returned to the original position by visually observing the light emitted from the light emitting device 123.
After the twist of the rope 2 is removed, the worker who gets on the scaffold 7 removes the nut 126 from the bolt 125, removes the bolt 125 from the plate portion 119, and displaces the plate portion 119 from the attachment position to the release position. At this time, the rope cover 121 is detached from the wheel 115 together with the plate portion 119. Then, the operator removes the rope 2 from the wheel 115.
Then, the rope 2 detached from the wheel 115 is wound around the hoist wheel 81 of the counterweight 8. The above-described steps are repeated until all the ropes 2 are wound around the hoist 81.
As described above, the elevator rope guide device 1 according to embodiment 1 of the present invention includes the guide device 101 and the sheave device 102 provided in the guide device 101, the guide device 101 is guided by the pair of guide rails 4 provided along the hoistway 3, and the sheave device 102 includes: a wheel 115 on which the U-shaped portion 21 of the rope 2 is wound from below during a rope winding operation; a wheel center shaft 116 that supports the wheel 115 and extends in a direction along a horizontal plane; a wheel support 117 that supports the wheel 115 via the wheel center shaft 116; and a rotation support portion 118 that rotatably supports the wheel support portion 117 such that the wheel center shaft 116 is displaced between a vertical position extending in a vertical direction perpendicular to a direction in which the pair of guide rails 4 face each other and an inclined position extending in a direction intersecting the vertical direction, and therefore, an operator can grasp whether or not the rope 2 is twisted in a state in which the U-shaped portion 21 is wound around the wheel 115 from below. Thus, the operator can detach the U-shaped portion 21 of the rope 2 from the wheel 115 with the twist of the rope 2 eliminated.
Further, since the elevator rope guide device 1 includes the rotation restricting portion that restricts the rotation range of the wheel supporting portion 117, the wheel 115 can be prevented from rotating more than once, and the rope 2 can be prevented from being entangled.
The guide device 101 further includes: a pair of guide portions 103 that are guided by the pair of guide rails 4, respectively; and a main beam 104 that is provided across the pair of guide portions 103 and supports the wheel device 102, and the main beam 104 is disposed so as to be shifted in the vertical direction with respect to the region where the pair of guide rails 4 face each other, so as not to overlap the already-installed rope 2, that is, the already-installed rope, in the height direction, and therefore, when the guide device 101 hangs down along the guide rails 4, the guide device 101 can be prevented from coming into contact with the already-installed rope.
Further, since the wheel 115 can rotate about the wheel center axis 116, when the elevator rope guide device 1 hangs down, it is possible to prevent sliding friction from occurring between the wheel 115 and the rope 2, and to prevent abrasion of the rope 2.
Further, since the elevator rope guide device 1 includes the rotation regulating portion 120, the rotation regulating portion 120 is provided across the guide device 101 and the wheel device 102, and the rotation of the rotation supporting portion 118 is regulated when the position of the wheel center axis 116 is the vertical position, it is possible to prevent the wheel center axis 116 from being displaced from the vertical position to the inclined position when the elevator rope guide device 1 is suspended.
Further, since the guide device 101 has a pair of guide portions 103 that are guided by the pair of guide rails 4, respectively, each of the guide portions 103 has a plurality of roller devices 106, the roller devices 106 include a pair of rollers 105 that sandwich the guide rail 4 in the width direction, and the plurality of roller devices 106 of the guide portions 103 are provided separately in the longitudinal direction of the guide rail 4, the guide device 101 can stably hang down along the guide rail 4. In particular, even when the main beam 104 is disposed so as to be offset in the vertical direction with respect to the region where the pair of guide rails 4 face each other, and so as not to overlap the already-installed rope 2, i.e., the already-installed rope in the height direction, the guide device 101 can stably hang down along the guide rails 4.
The guide device 101 includes a pair of guide portions 103 that are guided by the pair of guide rails 4, and each guide portion 103 includes: a roller 105 that rolls on the guide rail 4; and a foreign matter removing unit 107 for removing foreign matter adhering to the roller 105 rolling on the guide rail 4, so that the roller 105 can smoothly roll on the guide rail 4.
The guide device 101 further includes: a pair of guide portions 103 that are guided by the pair of guide rails 4, respectively; and a main beam 104 provided across the pair of guide portions 103, the main beam 104 being capable of expanding and contracting so as to change the dimension between the pair of guide portions 103, so that the same elevator rope guide device 1 can be used even for a plurality of types of elevator devices having different dimensions between the pair of guide rails 4.
Further, since the guide device 101 includes the pair of guide portions 103 that are guided by the pair of guide rails 4, respectively, and each guide portion 103 includes a magnet and is attracted to the guide rail 4 by the magnetic force of the magnet, the guide portion 103 can be easily brought into contact with the guide rail 4.
Further, since the elevator rope guide device 1 includes the rope cover 121, and the rope cover 121 restricts the U-shaped portion 21 of the rope 2 wound around the wheel 115 from being separated from the wheel 115, the U-shaped portion 21 of the rope 2 can be prevented from being separated from the wheel 115 when the elevator rope guide device 1 is suspended along the guide rail 4.
Further, since the elevator rope guide device 1 includes the protective cover 122 provided below the guide device 101, and the protective cover 122 supports the guide device 101 when the protective cover 122 is placed on the temporary placement surface, it is possible to suppress transmission of an impact to the guide device 101 when the guide device 101 falls and the elevator rope guide device 1 collides with a member below the guide device 101, and to make the elevator rope guide device 1 stand by itself when the elevator rope guide device 1 is not used.
Further, since the elevator rope guide device 1 includes the pair of light emitting devices 123 and the light emitting devices 123 are provided so as to sandwich the wheels 115 in the radial direction when viewed from above, the operator can grasp the position of the elevator rope guide device 1 in the height direction of the hoistway 3 and can easily confirm which position of the vertical position and the inclined position the wheel center axis 116 is located in.
In addition, although the elevator rope guide apparatus 1 used in the rope winding operation in which the rope 2 is wound around the sheave of the counterweight has been described in embodiment 1, it may be used in the rope winding operation in which the rope is wound around another sheave.
