Description

The present invention relates to a hoisting machine unit and a method for installing the hoisting machine unit.

Traditionally, elevators transport passengers and luggage to any floor by moving the car in the hoistway. Such an elevator requires a hoisting machine as a drive machine, and as an installation method thereof, for example, a type in which a hoisting machine is provided in a machine room provided separately from the hoistway, and a hoistway without a machine room. There is a machine roomless type equipped with a hoist inside.

If the machine room cannot be installed directly above the hoistway due to space restrictions in the ceiling direction, the so-called horizontal pulling method can be used in which the hoisting machine is installed in the machine room provided on the side of the hoistway. is there.

In the case of the horizontal pulling method, a hoisting machine for the horizontal pulling method and other peripheral equipment are required, and it takes time and effort to manufacture. In order to solve this difficulty, there is a method of devising an installation method so that a normal hoisting machine can be utilized, rotating it by 90 ° from the original hoisting machine form, and arranging it vertically. As a result, the space on the installation surface can be reduced.

However, since it is not possible to tilt it to a predetermined shape when the equipment is shipped, it is necessary to tilt it within a limited space during field work and place it in the installation position.

Further, when a heavy object such as a hoist is lifted to a predetermined installation position, rotated and installed, it is necessary to consider the stability so as not to lose the balance. Conventionally, when lifting a hoisting machine attached to a machine beam, so to speak, a hoisting machine unit, the position of the hanging hole for locking the pulling body of the lifting sling rope is set higher than the position of the center of gravity of the total weight. Ingredients have been proposed.

<First Embodiment>
Hereinafter, as an embodiment of the present invention, the hoisting machine unit and its installation method will be described with reference to the drawings.

FIG. 1 is a diagram showing the overall configuration of a horizontal pulling type elevator, and shows a state in which the hoisting machine unit is rotated by 90 ° from the original form and arranged substantially perpendicular to the floor surface of the machine room. ..

A machine room 2 is provided so as to be connected to the side of the hoistway 1, and a hoisting machine unit 10 is provided therein. The hoisting machine unit 10 is composed of a hoisting machine 11, a machine beam 12, and a submachine beam 13, and the details will be described later. A car 3 and a counterweight 4 are housed in the hoistway 1, and each of them is connected to the main rope 5. The main rope 5 is suspended on the traction sheave 11a of the hoisting machine 11 via the deflecting sheave 6.

When the traction sheave 11a is rotated by the driving force, the main rope 5 moves, and the car 3 and the counterweight 4 move up and down along a guide rail (not shown).

FIG. 2 is a perspective view of the hoisting machine unit 10, and FIG. 3 is a left side view of the hoisting machine unit 10 on which the main rope 5 is suspended.

The hoisting machine 11 is composed of a traction sheave 11a, a brake 11b, a brake disc 11c, and a motor 11d, and has a machine beam fastening portion 11e at the lower part of the hoisting machine 11. The machine beam 12 forms one machine beam 12 by pairing the steel members 12a and 12b. Bolts are inserted and fastened into the machine beam fastening portions 11e provided at two places on each of the two mounting surfaces at the lower part of the hoisting machine 11, and the hoisting machine 11 is fixed to the upper surface of the machine beam 12.

Similar to the machine beam 12, an installation member made of a combination of steel members 13a and 13b, that is, a submachine beam 13 is provided perpendicular to the machine beam 12 at the end of the machine beam 12. By directly connecting the machine beam 12 and the sub-machine beam 13 using bolts, and inserting another bolt via the joint 14, the machine beam 12 and the joint 14 and the sub-machine beam 13 and the joint 14 are fastened, respectively. , Consists of an L-shaped hoisting machine support.

The machine beam 12 is a member arranged between the wall surface and the beam when the hoisting machine 11 is installed in the machine room 2, and is in the direction in which the main rope 5 suspended from the traction sheave 11a is towed. Therefore, it functions as a hoisting machine stand that supports the hoisting machine 11. Further, as shown in FIG. 3, the traction sheave 11a in the hoisting machine 11 protrudes from the machine beam 12 to the suspended side of the main rope 5, that is, to the right in the figure.

In this embodiment, as shown in FIG. 4, both the machine beam 12 and the submachine beam 13 use a combination of two steel members 12a / 12b and 13a / 13b. By changing the distance between the steel member 12a and the steel member 12b, the installation width of the machine beam 12 in the depth direction can be adjusted, and it can be applied to various hoisting machine types. As shown in FIG. 5, the machine beam 12 and the submachine beam 13 may each have a shape in which one member supports the hoisting machine 11.

Further, in the vicinity of the ends of the machine beam 12 and the submachine beam 13, through holes 12c and 13c are provided as suspension sources for hoisting the hoisting machine unit 10. That is, in the machine beam 12, a through hole 12c is provided in the vicinity of the junction with the submachine beam 13 and the end on the opposite side thereof, and in the submachine beam 13, the junction with the machine beam 12 and the end on the opposite side thereof are provided. Through holes 13c are provided in the vicinity of the above, and the structure is substantially symmetrical. A rope for work used for heavy duty work can be passed through the through holes 12c and 13c, and functions as a point where a load is applied when hoisting the hoisting machine unit 10. Other members may be used as long as they function as a hanging portion. For example, an eye plate 15A or an eyebolt hook as shown in FIG. 6 or 7 is attached to the ends of the machine beam 12 and the submachine beam 13. A hooking portion such as 15B may be attached, and the through holes 12c', 13c', 12c ", 13c" in the hooking portion may be used instead of the through holes 12c and 13c. The hoisting machine unit 10 can be lifted by using the hanging portions such as the through holes 12c and 13c and the hooking portion.

FIG. 8 is a diagram showing a procedure for lifting the hoisting machine unit 10 of the present embodiment and rotating it by 90 °. Work in steps I, II, and III. In this embodiment, the hoisting machine unit 10 is rotated clockwise.

At the time of rotation, a work rope 16 and a hanging source of the ceiling hook are required as a hanging tool for lifting the hoisting machine unit 10. A chain block and a slinging rope are used for the work rope 16. The slinging rope part passed through the hanging part is connected to the chain via a hook. Since the chain block beyond that is equipped with a mechanism that can adjust the required amount while maintaining the length of the chain, the length of the entire work rope 16 can be safely adjusted by using the chain block. It is possible to properly carry out the weighting work of connected heavy objects.

In step I, first, the first work rope 16 is passed through the through hole 12c on the left side of the machine beam 12, and the second work rope 16 is passed through the through hole 13c on the upper side of the submachine beam 13. Hereinafter, the rope on the left side connected to the hoisting machine unit 10 will be referred to as 16a as the first rope, and the rope on the right side connected to the hoisting machine unit 10 as the second rope will be referred to as 16b. These work ropes 16 hold a chain portion extending from each rope by two workers via a hanging source of a ceiling hook provided in the upper part of the machine room. Then, the two workers adjust the chain in the direction of pulling the work rope 16, shorten the chain portion extending from both the left and right work ropes 16, lift the hoisting machine unit 10 from the floor surface 18, and lift it.

In step II, the rope 16a on the left side with the through hole 12c as the suspension source is towed, and the rope 16b on the right side with the through hole 13c as the suspension source is loosened to start rotating the hoisting machine unit 10 clockwise. At this time, when the rope 16a on the left side is towed, the length of the chain portion from the chain block to the through hole 12c is gradually shortened, and when the rope 16b on the right side is loosened, the length of the chain portion from the chain block to the through hole 13c is gradually shortened. The rope gradually becomes longer. The length of each work rope 16 is continuously adjusted, and the position of the through hole 12c gradually rises through the position where the line segment connecting the through hole 12c and the through hole 13c is parallel to the floor surface 18, that is, the horizontal plane. In the direction, the position of the through hole 13c is gradually changed downward. Therefore, the submachine beam 13 approaches parallel to the floor surface 18.

Rotate 90 ° from the original form, and lengthen both work ropes 16 when the submachine beam 13 is approximately parallel to the floor surface 18 and the machine beam 12 is approximately perpendicular to the floor surface 18 as in step III. Then, the hoisting machine unit 10 is placed so that the submachine beam 13 is in contact with the floor surface 18.

After that, the hoisting machine unit 10 is moved to the wall surface of the machine room 2 or the installation position of the installed beam in a state of being rotated by 90 °, and is attached to the wall surface or the installed beam. The submachine beam 13 is in contact with the floor surface 18 of the machine room 2, but may be further fixed with bolts or the like.

In the weight of the hoisting machine unit 10, in step I, the through hole 13c exists at a position higher than the center of gravity 17 of the entire hoisting machine unit 10, and the through hole 12c exists at a position lower than the center of gravity 17. Therefore, it is unstable to lift the machine beam 12 while maintaining the horizontal state, but as in step II, as the hoisting machine unit 10 is rotated, the line segment connecting the two suspension portions becomes a horizontal plane. The position of the center of gravity 17 is lower than that of the two hanging sources, so that the center of gravity 17 becomes stable. Further, by continuing the rotating operation clockwise so that the submachine beam 13 is in contact with the floor surface 18, the hoisting machine unit 10 can be rotated perpendicularly to the original state and installed in a predetermined state. ..

As described above, according to the hoisting machine unit and the installation method of the present embodiment, as shown in FIG. 8, when the hoisting machine unit is installed at an angle of clockwise, the through hole 13c located on the right side of the drawing is the hoisting machine unit. By providing the through hole 12c at a position higher than the center of gravity 17 of the entire 10 and lowering the through hole 12c at a position lower than the through hole 13c, when the hoisting machine unit 10 is rotated clockwise, the through hole 12c and the through hole 13c are formed. Stability increases as the line connecting the lines approaches horizontal. When the tilting direction is different, for example, when rotating counterclockwise, as shown in FIG. 9, the position of the through hole 13c higher than the center of gravity 17 of the entire hoisting machine unit 10 is provided so as to be on the left side of the drawing. The other through hole 12c is provided at a position lower than the through hole 13c.

That is, in any case, the two hanging portions for lifting the hoisting machine unit 10, that is, the through holes 12c and 13c are provided at positions that do not exist on the same horizontal plane with respect to the machine beam, and are on the side to be tilted. The hanging portion may be set at a position higher than the center of gravity 17 of the entire hoisting machine unit 10. According to this, it is possible to improve workability and appropriately arrange the hoisting machine unit 10 at the installation position while ensuring stability when rotating and installing the hoisting machine unit 10.

<Second embodiment>
Next, the second embodiment will be described with reference to FIGS. 10 and 11. The second embodiment further includes a support portion for supporting the hoisting machine 11 in addition to the first embodiment described above.

FIG. 10 is a perspective view of the hoisting machine unit 20 including the support portion according to the second embodiment.

In addition to the configuration of the hoisting machine unit 10 of the first embodiment, a support portion 21 made of a steel member extending in parallel with the machine beam 12 from an end portion of the submachine beam 13 is provided. The extended support portion 21 and the top of the hoisting machine 11 are in contact with each other. At this time, the height of the submachine beam 13 installed on the machine beam 12, that is, the length of the submachine beam 13 in the longitudinal direction is the height from the surface where the hoisting machine 11 is fixed to the machine beam 12, that is, the length in the vertical direction. Is almost the same as. For example, the length of the submachine beam 13 in the longitudinal direction is about 90% to 110% with respect to the height of the hoisting machine 11. The support portion 21 may have a length of at least up to the top of the hoisting machine 11, but may be a member longer than that.

One end of the support portion 21 is fastened to the submachine beam 13 by inserting a bolt into the joint 19 which is a connecting member. Further, a bolt is inserted into the hoisting machine fastening portion 21a provided in the support portion 21 to fasten the hoisting machine 11 and the support portion 21. The hoisting machine 11 is provided with a hole for receiving a bolt in advance at a connection position with the hoisting machine fastening portion 21a.

The support portion 21 fixed to the submachine beam 13 and the hoisting machine 11 is configured to gradually receive a load from the top of the hoisting machine 11 when the hoisting machine unit 20 is rotated and installed with respect to a horizontal plane. As a result, the connection of each member in the hoisting machine unit 20 becomes stronger, and the stability of the hoisting machine unit 20 during rotation is improved.

FIG. 11 is a diagram showing a procedure for lifting and rotating the hoisting machine unit 20 of the second embodiment. As in the first embodiment, the work is performed in steps I to III.

As described above, according to the hoisting machine unit 20 of the second embodiment, the hoisting machine 11 is surrounded by the machine beam 12, the submachine beam 13, and the support portion 21 and can be fixed, so that a load is applied. The directions are dispersed and the stability is improved. That is, according to the hoisting machine unit 20 of the second embodiment, the hoisting machine unit 20 is provided with a support portion 21 that supports the top of the hoisting machine 11, and the stability when the hoisting machine unit 20 is rotated and installed can be further improved. it can.

<Third Embodiment>
Next, the third embodiment will be described with reference to FIGS. 12 to 14. The third embodiment further has a hanging portion on the support portion 21 of the second embodiment described above.

FIG. 12 is a perspective view of the hoisting machine unit 30, and FIG. 13 is a plan view of the hoisting machine unit 30 as viewed from directly above.

The support portion 31 has a through hole 31a as a suspension base portion on which the work rope 16 is hung when lifting. Instead of the through hole 31a, a hooking portion such as the eye plate 15A shown in FIG. 6 or the eyebolt hook 15B shown in FIG. 7 may be used as the hanging portion.

One end of the support portion 31 is fastened to the submachine beam 13 by inserting a bolt into the joint 19 as in the second embodiment. Further, a bolt is inserted into the hoisting machine fastening portion 31b provided in the support portion 31 to fasten the hoisting machine 11 and the support portion 31. The hoisting machine 11 is provided with a bolt receiving hole in advance at the connection position with the hoisting machine fastening portion 31b, as in the second embodiment. The length of the support portion 31 when joined to the submachine beam 13 is shorter than the length of the machine beam 12.

FIG. 14 is a diagram showing a procedure for lifting and rotating the hoisting machine unit 30 of the third embodiment. Work in steps I to V. Steps I and II are the same as in the first and second embodiments. Two working ropes 16 are passed through the through holes 12c and 13c, and each is pulled up to float the hoisting machine unit 30. Then, while shortening the rope 16a on the left side and lengthening the rope 16b on the right side, the hoisting machine unit 30 starts rotating.

In step III, the through hole 13c of one of the two hanging portions to which the load is applied is replaced with the newly provided through hole 31a. At this time, a new third rope 16c different from the ropes 16a and 16b used so far is hung on the through hole 31a, and the right rope 16b hanging on the through hole 13c is removed.

In step IV, the rope 16a on the left side is fixed by the chain block in the length from the hanging source of the ceiling hook to the through hole 12c, and the third rope 16c replaced on the right side is gradually lengthened and rotated clockwise. To proceed.

By advancing the rotation in this way, it is possible to rotate 90 ° as in step V.

When the hoisting machine unit 30 becomes vertical, both working ropes 16 are lengthened and placed so that the submachine beam 13 is in contact with the floor surface 18.

As described above, from step I to step II, the balance of the hoisting machine unit 30 becomes stable as the line segment connecting the two through holes 12c and 13c approaches parallel to the horizontal plane. In step III, when the rope 16c with the chain portion shortened in advance is attached to the through hole 31a and the position of the hanging source is changed to further rotate the rope, the line segment connecting the through hole 13c and the through hole 31a is aligned with the horizontal plane. Since it approaches parallelism, it can be stably rotated to the position shown in step IV. Therefore, in the third embodiment, a force toward the next stable position acts from step III to step IV in FIG. 13, as compared with the above-described embodiment in which the through holes 12c and 13c are pulled up to the end. Therefore, it is possible to rotate 90 ° more easily, and the work load can be reduced. Stability is improved by using three hanging parts.

Further, in the first embodiment and the second embodiment, in step II, there are two hanging sources of the ceiling hook (not shown) and two hanging sources of the hoisting machine unit 10, that is, through holes 12c and 13c. As for the positional relationship with, the through holes 12c and 13c are present on the outer side. According to the law of force balance and action / reaction, the direction of the force applied to the object itself is determined by the lifting position and angle, and when a left-right outward force is generated, it becomes unstable. Since the two work ropes 16 form a V shape and an outward force is generated on the hoisting machine unit 10, it is difficult to balance the ropes, and when the ropes are stopped, rolling is likely to occur. Therefore, from step II to step III, it is necessary to keep moving both the left and right ropes 16a and 16b to secure the balance when the hoisting machine unit 10 rotates.

On the other hand, in the third embodiment, after replacing one hanging portion from the through hole 13c with the through hole 31a on the way, the hoisting machine unit 10 is more than the two hanging sources of the ceiling hook (not shown). Two hanging portions, that is, through holes 12c and 31a are located inside. Therefore, even if the towing of the rope 16a on the left side is stopped in the middle, the stability of the hoisting machine unit 10 is not impaired. Therefore, the hoisting machine unit 10 can be rotated by adjusting the length of the rope 16b on the right side without moving the through hole 12c as a base point. Therefore, since it is not necessary to continue towing the rope 16a on the left side, it is possible to rotate the rope even if the distance from the floor surface 18 to the ceiling is smaller than that of the first embodiment or the second embodiment. ..

As described above, according to the hoisting machine unit 30 of the third embodiment, the support portion 31 that supports the top of the hoisting machine 11 is further provided with a hanging portion, that is, a through hole 31a, so that a total of three can be obtained. Of the hanging parts of the place, the first half uses the through hole 12c and the through hole 13c, the through hole 13c is switched to the through hole 31a in the middle, and the second half uses the through hole 12c and the through hole 31a according to the situation. The hanging part can be used properly, and the stability and workability when rotating and installing can be further improved.
