Description

Description: TECHNICAL FIELD The present invention relates to an elevator hoist supporting device for supporting a hoist installed in a machine room on the side of a hoistway.

[Prior Art] Generally, this type of device is disclosed in, for example, Japanese Patent Laid-Open No. 60-213678, and will be described here with reference to FIGS. 4 to 6. 1 is a hoistway, 2 is a machine room that is provided on one side of the hoistway 1 and opens to the hoistway 1, 3 is a machine stand installed on the floor 2a of the machine room 2, and 4 is a machine stand 3 The hoisting machine 5 is a car provided in the hoistway 1, 6 is a return wheel provided at the upper end of the hoistway 1, and 7 is one end connected to the car 5 and is hung on the return wheel 6. The other end is a rope connected to the drum 4a of the hoist 4.

Then, the drum 4a is rotated by driving the electric motor of the hoisting machine 4, a rope 7 is wound around the drum 4a to raise the car 5, and the rope 7 is paid out from the drum 4a to lower the car 5. Further, 8 is a fixing plate that abuts on the side surface of the machine room 2 of the pit portion 1a formed at the lower end of the hoistway 1, and 9 is anchor bolts and nuts for fixing the fixing plate 8 to the side surface of the pit portion 1a. Is a fastener.

Normally, when the machine room 2 is lower than the lowest floor landing, it is not necessary to make the bottom surface of the pit 1a lower than the floor surface of the machine room 2, but as described above in order to attach the fixing plate 8. It is necessary to secure the pit portion 1a by digging deeply.

On the other hand, it is possible to make the floor surface of the machine room 2 and the bottom surface of the pit portion 1a at the same height without providing the pit portion 1a in this way, and in this case, there is a space for providing the fixing plate 8. Since the hoisting machine 4 is not fixed to the floor,
It will be done by installing anchor bolts on the floor.

[Problems to be Solved by the Invention] However, when the anchor bolt is attached to the floor of the machine room 2, tension from the rope 7 acts on the anchor bolt, so that the reliability of the anchor bolt is improved.
Although an embedded anchor bolt will be used, in the case of the embedded type, it is difficult to install the anchor bolt accurately because of building errors and the like, and therefore the position of the hoisting machine also involves an error.

Then, this invention is made in order to eliminate such a problem, and an object of this invention is to obtain the support device of the elevator hoisting machine which does not produce an error in the position of a hoisting machine.

[Means for Solving the Problems] The present invention relates to a supporting device for supporting a hoisting machine installed in a machine room provided on a side of a hoistway, wherein the hoisting machine extends in the axial direction of the drum. , And a support beam positioned on the machine room side of the winding end of the rope with respect to the drum is fixed to the side wall of the machine room via fixing plates, and both end portions of the support beam are fixed. A support member for supporting the hoisting machine is provided inside the fixing plate, and the lower end portion of the support member is fixed to the floor of the machine room by a fastener.

[Operation] Since the present invention is fixed as described above, even if the tension of the rope acts on the hoisting machine, the supporting beam is located inside the winding end of the rope with respect to the drum. Only compressive or shearing forces will be exerted on the connector.

Embodiments Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, the same reference numerals as those in FIGS. 4 to 6 indicate the same or corresponding portions.

Support plates 10 and 10 are attached to each of a pair of side surfaces orthogonal to the axis of the drum 4a of the machine base 3, and rectangular square holes 11 are formed in the support plates 10 and 10 at positions facing each other. A support beam 12 having an I-shaped cross section is inserted into the square hole 11, and both ends of the support beam 12 are fixed to the side wall of the machine room 2 via fixing plates 13 and 13. The length of the support beam 12 is slightly smaller than the depth dimension of the machine room 2, that is, the distance between both side surfaces of the machine room 2 parallel to the support plates 10 and 10, and the position thereof is the winding of the rope 7 around the drum 4a. It is installed inward of the end (load point). Reference numeral 14 is a vibration-proof rubber provided between the machine base 3 and the hoist 4, and 15 is a base for supporting both ends of the support beam 12,
Used when the support beam 12 is temporarily placed, and the support beam 12 is fixed to the fixing plate 13,1.
After being fixed to the machine room 2 by 3, it is removed.

As described above, the supporting device for the elevator hoisting machine according to the present embodiment is the same as the supporting device for supporting the hoisting machine 4 installed in the machine room 2 provided on the side of the hoistway 1. Drum 4a
Rope 7 extending along the axis of the
The support beam 12 located closer to the machine room 2 than the end of the winding is attached, both ends of the support beam 12 are fixed to the side wall of the machine room 2 via the fixing plates 13, and further, both ends of the support beam 12 are fixed. A support member 18 for supporting the hoisting machine 4 is provided inward of the plate 13, and the support member 18 is provided.
The lower end of 18 is fixed to the floor 2a of the machine room 2 by a fastener 19.

FIG. 3 is a detailed part of the II part of FIG.
Both side edges of the lower end portion of 12 are held by clips 16 and fixed by bolts 17 after positioning in the longitudinal direction is completed.

Returning to FIG. 1, 18 is a support member located inside the machine room 2 and supporting the machine base 3, and the lower end thereof is fixed to the floor of the machine room 2 by a fastener 19 made up of anchor bolts. Has been done. In this anchor bolt, since only the compressive force acts, not the tensile force, in the embedded type,
Suffering can be endured afterwards.

EFFECTS OF THE INVENTION As described above, in the elevator hoist supporting device of the present invention, the relative position between the support beam and the hoist can be set arbitrarily, and the fasteners can be post-strike. No matter how the depth of the machine room changes, only the length of the support beam needs to be determined, and in the factory, the parts other than the support beam need to be the same. Further, since the tensile force does not act on the fastener, it is not necessary to use the embedded type, and therefore even if there is an error in the building, no error occurs in the position of the hoisting machine.
