Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator that elevates and lowers an air conditioner, furniture, building materials, etc. between a place where a worker cannot reach, a place where it is difficult to support and a ceiling at a construction interior construction site or the like.

[0002]

[Prior art]

 Conventionally, for example, when installing an air conditioner on the ceiling, at present, several people are required to lift and install it while raising the stepladder, or a small number of people are using hydraulic jacks or mechanical jacks for large equipment.

[0003]

[Problems to be solved by the device]

 However, in the former case, it is necessary for several people to attach the air conditioner to the anchor bolt hung from the ceiling while raising this stepladder to the ceiling by several people and maintaining this state. However, there was a drawback that required many workers.

In addition, since the latter one requires a large elevator, it is inconvenient for one person to carry and handle the elevator. Furthermore, when an air conditioner is placed on the elevator, the central part is There was also a problem of instability such as tilting and slipping when it was displaced. Therefore, an object of the present invention is to provide a lifter that can be downsized and can lift and lower an air conditioner or the like by one person in a stable state in order to solve the above problems.

[0005]

[Means for Solving the Problems]

 The present invention has taken the following technical means in order to achieve the above object. That is, in the elevator according to the present invention, a screw gear that can communicate with the outside is rotatably supported in the lower part of a substantially cubic box-shaped body, and a spur gear that is screwed with the screw gear is rotatably supported above the screw gear. The wire winding reel is fixed to one side of the spur gear, and the tip end of the wire wound around the reel is projected upward through the through hole of the load receiving base provided on the upper part of the main body, and the protruding portion is formed. The feature is that a screwing member is attached to the uppermost end of the.

[0006]

[Action]

 According to the present invention, since the reel can be rotated through the spur gear by rotating the screw gear, the wire wound around the reel can be stretched or wound up. By screwing the screwing member at the uppermost end of the wire with an anchor bolt on the ceiling and placing an air conditioner etc. on the cargo receiving stand, rotate the screw gear to wind the wire on the reel. Air conditioners and other equipment can be lifted together with elevators.

[0007] Furthermore, when the above-mentioned ascending is stopped and the electric screwdriver that has rotated the screw gear is pulled out, the weight of the air conditioner and the elevator is added to the wire, and the spur gear is rotated through the reel. However, the spur gear is meshed with the screw gear and the stopper action of the screw gear allows the air conditioner and the elevator to be held at the stop position without descending.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 is a cubic box-shaped main body in which a spur gear 2 and a reel 3 are directly connected, and both end shafts 4, 4 thereof are pivotally supported by the main body 1. Above the reel 3, a pair of guide rollers 5 and 5 are axially supported in the main body 1, and a wire receiving hole 7 is provided in the load receiving base 6 on the guide rollers 5 and 5, and another large load receiving base is also provided. A plurality of bolt holes 8 are provided on which can be mounted and attached.

The free end of the stainless steel wire 9 wound around the reel 3 is projected above the wire through hole 7 through the guide rollers 5 and 5, and the uppermost part thereof is a screw member. The nut 10 of is connected. A screw gear 11 meshing with the spur gear 2 is axially supported by bearings 13 and 13 fixed to a bottom plate 12, and both ends of the screw gear 11 have hexagonal bolt holes 14 and 14 which rotate to the outside. Transmission cylinders 15 and 15 are connected in series, and these are detachably screwed to the main body 1 by a plurality of bolts 16. As shown by the chain double-dashed line in FIGS. 1 and 2, a locking hook 20 may be provided at the bottom of the bottom plate 12.

Reference numeral 17 is a bolt for tightening the covers 18, 18 surrounding both sides of the main body 1, and 19 is a screw hole for wire replacement. Since it is configured as described above, as shown in FIGS. 3 and 4, the lower portions of the support plates 22 provided at the four corners of the air conditioner 21 are supported by the load carrier 6 of the elevator. Next, insert a (rechargeable) electric screwdriver into the bolt holes 14, 14 of each elevator into the anchor nuts 24 ... embedded in the ceiling 23, and the anchor bolts 25 ... screwed into the anchor nuts 25 ..., and extend the wire 9 to extend its upper end. The nut (10) is raised and screwed into the anchor bolts (25). Further, each wire 9 is alternately wound by the bolt hole 14 through the screw gear 11, the spur gear 2, and the reel 3 to raise the air conditioner 21 to the position shown by the one-dot chain line in FIG. Remove the nut 10 from one anchor bolt 25, screw the air conditioner 21 to the anchor bolt 25 with a specified nut (not shown), and remove the nut 10 one by one with the anchor bolts 25 one by one. The air conditioner 21 is screwed by and the air conditioner 21 is attached inside the hole 27 of the ceiling plate 26.

In the above description, when the wire 9 is stretched, the bolt 16 is loosened and the screw gear 11 and the spur gear 2 are unscrewed, so that the spur gear 2 becomes rotatable, so that it is wound around the reel 3. The wire 9 can be stretched freely. After stretching the wire 9, the bolt 16 is retightened and the screw gear 11 and the spur gear 2 are screwed together. In addition, when the air conditioner 21 was raised, the elevators were individually raised. As shown in FIG. 5, each elevator 1 was provided with a small motor 29 that works in conjunction with the rotation transmission cylinders 15, By using the balance winder 30 that controls the operation of the small motor 29, it is possible to continuously raise the balance while maintaining the parallel state.

FIG. 6 shows an example of raising a beam pillar, furniture, etc. For example, when raising the furniture 40, the lower ends of both ends of the furniture 40 are supported by two elevators, and the preceding example (FIG. ~ 5) Similarly, it is to raise. Fig. 7 shows an example of raising furniture and distribution boxes. For example, when raising the distribution box 50, attach one elevator inside it and raise it in the same way as in the previous example (Fig. 6). It is what makes me.

In the above embodiment, the spur gear 2 is shown as a gear that meshes with the screw gear 11. However, the spur gear 2 is a spur gear formed with teeth inclined to match the inclination of the screw of the screw gear 11. Gears may be used. Also, a nut 10 is used as the screwing member, but this is adapted to the anchor bolt 25 of the ceiling 23.If the ceiling 23 side is the anchor nut 24 only, the bolt that meshes with it is the wire 9 It may be connected to the upper end, or the nut 10 may be screwed with an optional part (not shown) having nuts or bolts of various sizes.

Further, although the bolt holes 14 and 14 are used at both ends of the screw gear 11, only one of them may be used, and instead of the bolt holes 14 and 14, hexagon bolts may be used. (Rechargeable) You may attach and use a cylinder with a hexagonal bolt hole that fits the bolt on the electric driver side, and the design of the bolt holes 14, 14 can be changed in various ways. .

[0015]

[Effect of device]

 According to the present invention, the spur gear and the wire winding reel are directly connected and pivotally supported in the elevator body, and the screw gear that meshes with the spur gear is only pivotally supported, which is extremely simple. It can be miniaturized. Since the elevator is hung vertically with wires using the anchor bolts on the ceiling, it is possible to vertically raise the air conditioner, etc., which is placed on the load receiving platform, in a stable state.

Since the elevator is small and convenient for carrying and other handling, an air conditioner or the like can be installed on the ceiling by one person.
