Abstract

When a horizontal system in which a hoisting machine is mounted in a machine room provided on a side surface of a hoistway is adopted as an elevator mounting method, a dedicated hoisting machine is required. The present invention provides a traction machine unit with an installation clamp, which can effectively rotate a normal traction machine to a prescribed installation position and is properly configured, comprising: a traction machine; a mechanical beam supporting the traction machine; a suspension source part which is arranged near one end part of the mechanical beam in the length direction and is engaged with the lifting appliance; and a mounting jig provided near an end portion on the opposite side of the suspension source portion and having a rotation shaft fixed or engaged to the machine beam and a support portion having a through hole into which the rotation shaft is inserted, wherein the mounting jig is engaged with the support portion when the rotation shaft is fixed to the machine beam, and wherein the mounting jig is fixed or engaged with the support portion when the rotation shaft is engaged with the machine beam, and wherein a portion of the engaging hanger is positioned below a bottom surface of the machine beam to function as a base point when the suspension source portion is pulled and the traction machine is rotated, and wherein the traction machine is rotated to be mounted.

Description

Traction machine unit with mounting clamp and mounting method thereof

Technical Field

The present invention relates to a traction machine unit provided with an installation jig and an installation method thereof.

Background

Conventionally, an elevator transports passengers and cargo to an arbitrary floor by moving an elevator car in a hoistway. In this elevator, there are a type in which a hoisting machine is provided in a machine room provided independently of a hoistway, and a type in which a machine room is not provided but a hoisting machine is provided in a hoistway, as a method of installing the hoisting machine, as a driving machine.

When the machine room cannot be installed directly above the lifting path due to the limitation of the space in the ceiling direction, a so-called horizontal system is adopted in which the hoisting machine is mounted to the machine room installed on the side surface of the lifting path.

In the case of the horizontal system, since a traction machine dedicated to the horizontal system is required, it is necessary to manufacture equipment constituting the traction machine differently from usual equipment, and time and effort are required. To solve this difficulty, the installation method is studied so that a normal hoisting machine can be applied, rotated 90 ° from the original form of the hoisting machine, and vertically installed.

However, since the equipment cannot be tilted to a predetermined form when shipped, the equipment is required to be rotated in a limited space and placed at an installation position during field operation. Conventionally, in the case of attaching a hoisting machine attached to a machine beam, a so-called hoisting machine unit, as shown in fig. 23, both ends of the machine beam are used as a suspension source 110, and a work rope 120 serving as a hoist is engaged with the suspension source 110, and the whole hoisting machine unit 100 is rotated and attached. Note that the hoisting machine unit 100 is mounted to the wall surface 140 in a manner substantially perpendicular to the floor 130 from the original form by performing the work in three steps I to III without breaking the balance.

However, in this case, since it is necessary to provide a suspension source at least two positions including both ends of the mechanical beam and to lift the mechanical beam by a hanger such as a work rope, two workers who adjust the work rope need to perform work simultaneously at the same time, and in order to use two positions as suspension sources, it is necessary to sufficiently secure a space for suspending the work rope.

Detailed Description

Hereinafter, a traction machine unit including an installation jig according to the present embodiment and an installation method thereof will be described with reference to the accompanying drawings.

Fig. 1 is a diagram showing the overall structure of the horizontal elevator according to the present embodiment, and shows a state in which the hoisting machine unit is rotated clockwise by 90 ° from the original form of the hoisting machine unit, is perpendicular to the floor of the machine room, and is attached to the left wall surface.

A machine room 2 is provided in a form of being connected to a side of the elevating path 1, and a traction machine unit 10 is provided therein. An elevator car 3 and a counter weight 4 are accommodated in the hoistway 1, and are connected to main ropes 5, respectively. The main rope 5 is suspended from a traction sheave 12 of a hoisting machine 11 constituting the hoisting machine unit 10 via a deflector sheave 6. The main rope 5 moves by rotating the traction sheave 12 by the driving force of the hoisting machine 11, and the elevator car 3 and the counter weight 4 are lifted and lowered along a guide rail not shown.

Fig. 2 is a front view of the traction machine unit 10, and fig. 3 is a right side view thereof. The traction machine unit 10 includes a traction machine 11, a machine beam 14, a sub-machine beam 16, and a mounting jig 20.

The hoisting machine 11 is placed on the upper surface of the machine beam 14, and bolts are inserted into the machine beam fastening portions 13 provided at the lower portion of the hoisting machine 11 and fastened to the machine beam 14. Here, when the main rope 5 is suspended from the traction sheave 12 of the hoisting machine 11, the traction sheave 12 is positioned to protrude in the direction in which the main rope 5 is placed, i.e., in the left direction in fig. 3, from the mechanical beam 14 so that the main rope 5 does not contact the mechanical beam 14.

A suspension source 15 used when the hoisting machine unit 10 is suspended is provided at an end of the mechanical beam attached to the wall side, that is, at an end of the mechanical beam 14 on the left side in fig. 2. In the present embodiment, the suspension source 15 is formed of a through hole through which a rope (hereinafter, referred to as a work rope) used in a hoisting work passes, but an eye bolt or the like that forms a hook portion of a spreader may be used instead of the through hole. A sub-mechanical beam 16 is provided perpendicularly to the mechanical beam 14 near the other end of the mechanical beam 14 corresponding to the opposite side of the suspension source portion 15, and is connected to the mechanical beam 14 using bolts. The hoisting machine unit 10 directly connects the machine beam 14 and the sub-machine beam 16, and inserts other bolts through the joint 17, and fastens the machine beam 14 and the joint 17 and the sub-machine beam 16 and the joint 17, respectively, to construct an L-shaped support stand. The mechanical beam 14 is more firmly connected to the secondary mechanical beam 16 by means of the joint 17. However, in fig. 2, the auxiliary machinery beam 16 is fixedly installed on the installation surface of the hoisting machine 11 with respect to the machinery beam 14, but as shown in fig. 16 to be described later, the longitudinal surface of the auxiliary machinery beam 16 may be connected to the end of the machinery beam 14 from the lateral direction so that the end of the auxiliary machinery beam 16 contacts the floor 18. The L-shaped support base is provided with three rotation shafts 30 (see fig. 3) protruding from each other, and mounting jigs 20 are provided at both ends of the L-shaped support base with the respective rotation shafts 30 interposed therebetween.

The mounting jigs 20 mounted to the machine beam 14 and the sub-machine beam 16 will be described with reference to fig. 4 to 7. Since the mounting jig 20 attached to the machine beam 14 has the same structure as the mounting jig 20 attached to the sub-machine beam 16, the mounting jig 20 attached to the machine beam 14 will be described here as an example, and the description of the sub-machine beam 16 will be omitted.

As shown in fig. 4, the mounting jig 20 includes a support portion 21, a ball roller 23, and a jack 24 accommodated in a recess opening on the lower surface side of the support portion 21.

The support 21 has a through hole 22 into which the rotation shaft 30 is inserted.

The ball roller 23 is provided as a moving mechanism at a lower portion of the support portion 21, and protrudes downward from the bottom surface of the support portion 21. In the present embodiment, the ball roller 23 is used as the moving mechanism, but may be a sphere or an annular rotating body, or may be another shape such as a wheel.

The jack 24 has a mechanical pantograph shape as shown in fig. 5 as a height adjusting mechanism. The jack 24 incorporates a steel member 25, further comprising a threaded shaft 26 and a base 28. The screw shaft 26 is provided with a knob 27 at one end thereof interposed between the steel members 25 to be combined together, and the screw shaft 26 is rotated in a forward direction (clockwise) or a reverse direction (counterclockwise) in the circumferential direction by twisting the knob 27 in the circumferential direction of the screw shaft 26. The height of the jack 24 can be adjusted by the rotation mechanism of the screw shaft 26.

Next, the function of the mounting jig 20 according to the telescopic state of the jack 24 will be described with reference to fig. 6 and 7. The mounting clip 20 functions differently depending on the location of the jack 24.

Fig. 6 is a front view of the mounting jig 20, fig. 7 is a side view thereof, and 18 shows a floor. The floor 18 is, for example, a floor of the machine room 2 or the like. Fig. 6 (a) and 7 (a) each show a state in which the jack 24 is housed in the support portion, and fig. 6 (b) and 7 (b) each show a state in which the stretching jack 24 protrudes toward the floor side from the support portion 21 and even from the ball roller 23.

The jack 24 is normally housed in the support 21, and the bottom surface of the base 28 of the jack 24 is located at a position (a) above the bottom surface of the support 21. Since the ball roller 23 is in contact with the floor, a planar movement in cooperation with the floor 18 is enabled.

The height of jack 24 can be adjusted when knob 27 is turned. Accordingly, when the knob 27 is turned in the raising direction, the height of the jack 24 is extended, and the base 28 is lowered toward the floor 18 side. For example, the knob 27 can be turned manually.

After the abutment 28 contacts the floor 18, the supporting portion 21 is pushed up from the contact portion, and the ball-floating roller 23 is set in a state of the setting surface (b). The load of the traction machine unit 10, which is thus received due to the contact of the ball rollers 23 with the floor 18, moves toward the jack 24, and the jack 24 receives the load applied in the gravitational direction.

(modification of mounting jig)

While the description has been made of the configuration in which the ball roller 23 and the jack 24 are formed using different members, the attachment jig 20 may have a structure having a telescopic rotating body 29 that includes both a moving mechanism and a height adjusting mechanism as shown in fig. 8 (modification 1). In this case, when the planar movement is required, the ball roller 23 protrudes downward from the support portion 21 as shown in the figure, and the ball roller is in contact with the floor 18, and is housed in the support portion 21 when the planar movement is not performed.

Further, as shown in fig. 9, the ball roller 23 may be omitted, and the support portion 21 and the jack 24 may be provided (modification 2), or as shown in fig. 10, the support portion 21 may be provided alone (modification 3). In the case where the ball rollers 23 are not provided, it is difficult to move the hoisting machine unit 10 in parallel to the rotated installation position, and therefore it is effective to determine the installation position by rotating the hoisting machine unit 10, that is, if parallel movement is not required.

Next, a connection relationship of each component will be described. On the premise, a hole is provided in the mechanical beam 14 at a position where the mounting jig 20 is provided, and a rotary shaft 30 (see fig. 3) is inserted into the hole (not shown) to mount the mounting jig 20. On the other hand, in the mounting jig 20, the rotary shaft 30 is inserted into the through hole 22, and is mounted.

(installation method of installation jig)

A method of attaching the rotary shaft 30 applicable to the present embodiment will be described. The first method is a method in which, in the rotation shaft 30, the connection portion between the rotation shaft 30 and the mechanical beam 14 is fixed, and the rotation shaft 30 is engaged with the connection portion of the mounting jig 20 in a rotatable manner. The second method is a method of rotatably engaging the rotary shaft 30 with the connection portion of the mechanical beam 14 and fixing the connection portion of the rotary shaft 30 and the mounting jig 20. The third method is a method of rotatably engaging both the connection portion between the rotation shaft 30 and the mechanical beam 14 and the connection portion between the rotation shaft 30 and the attachment jig 20. The shaft is fixed, that is, the shaft is fixed when the shaft is fixed to the member, and the shaft is supported so as to be slidable in the circumferential direction when the shaft is engaged with the member. As shown in the first to third methods, in the rotary shaft 30, as long as at least one of the mechanical beam 14 and the mounting jig 20 is shaft-supported, the other may be either shaft-fixed or shaft-supported.

Hereinafter, a description will be given of a case of using a first method in which the mechanical beam 14 side is fixed to the rotation shaft 30 and the attachment jig 20 side is engaged so that the rotation shaft 30 is rotatable, as an example.

First, the connection relationship between the rotation shaft 30 and the mechanical beam 14 will be described. Fig. 11 is a perspective view showing a positional relationship of components and the like between the rotary shaft 30 and the mechanical beam 14, and fig. 12 is a cross-sectional view thereof.

The rotary shaft 30 is inserted into a hole provided in the mechanical beam 14, and a bracket 31 as a cylindrical steel member is provided on the outer periphery of the rotary shaft 30. The bolt 33 extends through the rotation shaft 30 to fasten the bracket 31 and the rotation shaft 30.

An annular plate 32 is provided on the outer periphery of the bracket 31, and the plate 32 and the bracket 31 and the plate 32 and the mechanical beam 14 are fixed by bolts, welding, or the like, not shown.

Thereby, the rotation shaft 30, which is shaft-fixed to the mechanical beam 14, is linked with the rotation operation of the mechanical beam 14.

Next, a connection relationship between the rotation shaft 30 and the mounting jig 20 will be described. Fig. 13 is a perspective view showing a positional relationship of components and the like between the rotation shaft 30 and the mounting jig 20, and fig. 14 is a cross-sectional view thereof. The bracket 31 and the rotation shaft 30 are fastened by bolts 33 in the same manner as the connection relationship between the rotation shaft 30 and the mechanical beam 14 shown in fig. 11. Instead of the plate 32, a bearing 34 is used, and an inner ring 34a of the bearing 34 and the bracket 31, an outer ring 34b of the bearing 34 and the mounting jig 20 are mounted by bolts or the like, not shown. A plurality of spherical rotors 34c are provided between the inner ring 34a and the outer ring 34b of the bearing 34, and the bearing has a function of being rotatable in the circumferential direction of the rotary shaft 30 in accordance with the rotation of the rotors 34 c.

The rotation shaft 30 can be inserted into the through hole 22 to be engaged, and the shaft is supported at a predetermined position of the mechanical beam 14, and the support portion 21 can slide with respect to the rotation shaft 30 by the bearing 34 without interlocking with the rotation movement from the rotation shaft 30.

In the present embodiment, the mounting jigs 20 are mounted near the both end portions of the rotation shaft 30 fixed to the mechanical beam 14, but one mounting jig 20 may be provided between two points connecting the rotation shaft 30 and the mechanical beam 14.

Although the case where the rotation shaft 30 and the mechanical beam 14 are fixed and the rotation shaft 30 and the mounting jig 20 are engaged has been described, the plate 32 and the bearing 34 may be separately used in the case where other connecting methods are used. In the case of the second method, a mechanism having a bearing 34 is provided in the connection of the rotation shaft 30 and the mechanical beam 14, and a mechanism having a plate 32 is provided in the connection of the rotation shaft 30 and the mounting jig 20. In the third method, a mechanism having a bearing 34 is provided at the connection portion of the rotation shaft 30 and the mechanical beam 14, or the rotation shaft 30 and the attachment jig 20, respectively. In this way, the site can be slidably supported by using a mechanism including the bearing 34.

The hoisting machine unit 10 is constructed as described above.

(rotation method of traction machine Unit 10)

Next, the steps in rotating the hoisting machine unit 10 will be described.

Fig. 15 is a diagram showing a position X, Y, Z where the attachment jig 20 is provided in the hoisting machine unit 10. The mounting jigs 20 are provided at one position near the left and right end portions of the mechanical beam 14, respectively, and the mounting jigs 20 are provided at one position of the upper end portion of the sub-mechanical beam 16, respectively, when viewed from the front. However, in the case where the auxiliary machine beam 16 is not placed on the surface of the hoisting machine 11 of the machine beam 14, but is connected to the end of the machine beam 14 from the lateral direction so that the end of the auxiliary machine beam 16 contacts the floor 18 as shown in fig. 16, the attachment jigs 20 may be provided one by one in the vicinity of the end of the auxiliary machine beam. Hereinafter, in order to show the difference in function between the mounting positions of the mounting jigs 20, the mounting jigs 20 mounted at the position X will be referred to as 20X, the mounting jigs 20 mounted at the position Y will be referred to as 20Y, and the mounting jigs 20 mounted at the position Z will be referred to as 20Z. Hereinafter, as the shape of the installation jig 20, a case will be described in which the hoisting machine unit 10 of the installation jig 20 shown in fig. 4 is installed using fig. 4, 8, 9, and 10. The connection to the rotation shaft 30 is performed using the first method.

Hereinafter, the operation steps of rotating the hoisting machine unit 10 by 90 ° will be described with reference to fig. 17.

The hoisting machine unit 10 is placed with the machine beam 14 substantially parallel to the floor 18. The lower end of the mounting jig 20 provided to the machine beam 14 is in contact with the floor 18, and when the suspension source 15 is suspended, the traction machine unit 10 can be rotated with the contact between the lower end of the mounting jig 20 and the floor 18 as a base point. This rotation is performed by steps I to IV shown below.

In step I, the knobs 27 of the mounting jigs 20X, 20Y of the mechanical beam 14 are first adjusted to be raised to a position where the ball rollers 23 are not in contact with the floor 18.

Further, a work rope 19 for hoisting the hoisting machine unit 10 is passed through the suspension source 15 of the mechanical beam 14. The work rope 19 includes a chain block and a sling rope. Then, the operator holds the work rope 19 passing through a suspension source, not shown, provided in the upper part of the machine room or in the ceiling, shortens the length of the chain portion of the work rope 19 little by little, and starts the traction of the hoisting machine unit 10.

At this time, as shown in step II, the hoisting machine unit 10 is tilted from the original position by pulling the work rope 19 with the attachment jig 20X as a base point, and the position of the suspension source 15 is gradually raised and rotated clockwise.

The worker pulls the work rope 19, and shortens the length of the work rope 19 from the ceiling to the suspension source, whereby the sub-mechanical beam 16 is nearly parallel to the floor 18 and the mechanical beam 14 is nearly perpendicular to the floor 18 from the state of step II to step III.

When the hoisting machine unit 10 is approximately vertical from the original position as in step III, the traction is stopped, the knob 27 of the mounting jig 20Z attached to the sub-mechanical beam 16 is adjusted in accordance with the height of the jack 24 of the mounting jig 20X serving as the base point, and the jack 24 in storage is extended. As a result, the traction machine unit 10 is stabilized as in step IV from the state in which the load is applied only to the mounting jig 20X to the state in which the load is applied to both the mounting

jigs

20X and 20Z.

Thereafter, the jacks 24 of the mounting

jigs

20X and 20Z are adjusted to the positions to be accommodated in the supporting portions 21, and the respective ball rollers 23 are brought into contact with the floor 18. After one operator who rotates the hoisting machine unit 10 removes the work rope 19 attached to the suspension source 15, the hoisting machine unit 10 is moved in parallel to a correct attachment position by the ball rollers 23 as needed. The machine beam 14 is then attached to the inner wall surface of the machine room 2, and the sub-machine beam 16 is attached to the floor 18 of the machine room 2. Depending on the mounting position, the mechanical beam 14 may be mounted on a post provided separately from the inner wall surface, or the sub mechanical beam 16 may be mounted on a beam provided separately from the floor 18.

As described above, the traction machine unit 10 can be rotated clockwise and mounted at a predetermined position by performing the work through the steps I to IV.

As shown in fig. 18, the following procedure may be adopted: that is, in step I, all the mounting

jigs

20X, 20Y, and 20Z are raised in advance so as to protrude to the lower surface side by the same height, and in this state, the sub-mechanical beam 16 is rotated to be substantially parallel to the floor 18, and then all the jacks 24 are restored to the original state. For the extended state of the jack 24, refer to the shape of (b) in fig. 6.

The mounting jigs 20Y and 20Z are used for plane movement before or after rotation of the hoisting machine unit 10, and thus the mechanism of fig. 4 and 8 having a rotating body is applicable, but the mounting jigs 20X may have a structure having neither the ball roller 23 as shown in fig. 9, nor the jack 24 nor the ball roller 23 as shown in fig. 10. In the case where the jack 24 is not provided as the height adjusting mechanism, the lower surface of the support portion 21 of the mounting jig 20 is provided to be located at the lower portion of the bottom surface of the mechanical beam 14 in order to rotate the hoisting machine unit 10.

In the present embodiment, the mounting jigs 20 are mounted at three positions of the hoisting machine unit, but the mounting jigs 20 may be provided at least at the position X. The traction machine unit may have a shape that does not have the auxiliary machinery beam 16, that is, a shape of the traction machine unit shown in fig. 19 and 21. In this case, the suspension source 15 is provided at one end of the mechanical beam 14, and the mounting jig 20 is provided at the other end.

Fig. 19 and 21 are structures of a hoisting machine unit including a mounting jig 20 near an end portion of the mechanical beam 14 opposite to the suspension source portion 15. Fig. 20 is an enlarged front view illustrating the periphery of the mounting jig 20 of fig. 19, and fig. 22 is an enlarged front view illustrating the periphery of the mounting jig 20 of fig. 21 as well. As the mounting jig, fig. 19 and 20 show a mounting jig having the support portion 21, the ball roller 23, and the jack 24, or a mounting jig having the support portion 21 and the telescopic rotating body 29 shown in fig. 8, and fig. 21 and 22 show a mounting jig having the support portion 21 alone shown in fig. 10, or the support portion 21 and the jack 24 shown in fig. 9. In the case of these shapes, the mounting jig 20 can be rotated clockwise as a base point.

The structure of the composite mechanical beam 14 and the sub mechanical beam 16 shown in fig. 2 and 16, and the structure based on only the mechanical beam 14 shown in fig. 19 may be referred to as a mechanical beam member. The machine beam member need not be of the structure shown in the drawings as long as it supports the hoisting machine 11, and for example, a plurality of sub-machine beams may be used.
