Definitions
- the present invention relates to an electric hoist that lifts and lowers heavy objects in a cargo handling operation, and relates to a structure in which an electric winch is a main part and is always hung horizontally.
- Electric winches have a relatively simple structure in which a drum is connected to the drive shaft of an electric motor such as a geared motor via a speed reduction device as appropriate, and a wide variety of types are available depending on the price and capacity.
- FIG. a structure is disclosed in which the arm 51 is protruded horizontally to the pole 50 and fixed, and the electric winch 52 is fixed to the arm 51.
- a clamp 54 provided with a socket 53 is attached to the pole 50, and a wedge 55 is welded to the tip of the arm 51.
- the arm 5 is connected to the wedge 55 by inserting the wedge 55 into the arm 53. 1 is fixed to poll 50.
- the other end of the arm 51 is supported by a brace 56.
- the electric winch 52 is provided with a cover frame 57, and a bracket 58 that can communicate with the arm 51 is provided at two places on the upper surface of the cover frame 57.
- the electric winch 52 is fixed to the arm 51 by passing the bracket 58 through the arm 51.
- the electric winch 52 is used as an electric hoist because the wire 60 (which may be a rope or a chain) wound around the drum 59 is suspended. be able to. Also, since the electric winch 52 is fixed by brackets 58 at two places, it does not tilt when lifting heavy objects. The electric winch 52 does not tilt, and as a result, the positional relationship between the wire 60 and the drum 59 is maintained in an appropriate state. From the standpoint of preventing unpacking, it is an important factor for safe cargo handling.
- the pole 50 needs to be erected at a place where cargo handling work is performed in a factory or a warehouse.
- the use of the pole 50 is limited because it is not permanently installed in the building. It is not reasonable to construct a new pole 50 in a factory or warehouse.
- the arm 51 may be installed on the ceiling side of the building, and at this time, the port 50 is omitted.
- the cargo handling work is limited to the position where the arm 51 is erected.
- the simplest way to fix the electric winch 52 is to suspend the electric winch 52. In other words, if there is only a hanging tool such as a wire at the loading place, the electric winch 52 can be used as an electric hoist by hanging it.
- FIG. 7 shows an example thereof, in which a hook 61 is provided on an electric winch 52.
- the hook 61 is provided on the center of gravity of the empty winch 52.
- the electric winch 52 is kept horizontal by hooking the wire 62 suspended from an appropriate location on the ceiling to the hook 61. Since the electric winch 52 has a structure in which the motor and the drum are arranged side by side, a load is applied to the drum side when lifting and lowering, and as a result, the overall center of gravity shifts, and the electric winch by the weight of the load 52 is inclined to the drum 59 side. Carrying work with the electric winch 52 tilted is dangerous because, as described above, one wire of the wire 60 is generated. Since the weight varies depending on the load, the position of the hook 61 cannot be set in advance on the center of gravity at the time of lifting.
- An object of the present invention is to provide an electric winch suspended electric hoist which maintains a flat posture in any cargo handling work. Disclosure of the invention
- the present invention provides an electric winch section in which a drum is connected to a drive shaft of a motor side by side, and a suspension provided on a center of gravity of the electric winch section in a horizontal state of empty load.
- a lower hook on the opposite side of the hook, a first roller for changing the direction of a wire fed from the drum toward the center of gravity, and a wire from the first roller to a vertical line from the center of gravity.
- the electric hoist was composed of the second roller that was turned downward in coincidence.
- the hook suspends the electric winch and may be a ring. This hook is provided directly on the electric winch portion or, for example, on the cover frame described in the background art.
- the wire fed from the drum is wound in the order of approximately the lower half of the first roller and approximately the upper half of the second roller, and repositioned until it coincides with the vertical line from the center of gravity (hook) of the electric winch. Is done.
- the center of gravity of the suspension of the electric winch coincides with the center of gravity of lifting and lowering the load, so that the hoist is always in a balanced state regardless of whether it is empty or unloaded.
- the roller can be constituted by, for example, a cylindrical shaft having a fixed length.
- the wire is wound directly on the shaft.
- the integral means (fixing method) for the electric winch portion of the mouthpiece is not limited. However, by rotatably fixing the shaft, the wire can be smoothly fed and wound when the load is lifted and lowered, and the friction between the shaft and the wire can be reduced.
- the roller may have a configuration in which a sheave is inserted and fixed to the shaft.
- the sheave is the one around which the wire is wound. If the wire is directly wound around the shaft, the wire may move on the shaft when the load is lifted and lowered. Therefore, it is preferable to use a sieve inserted and fixed to the shaft.
- the shaft can also be rotatably fixed (however, the sheave rotates together with the shaft), and the operation and effect are as described above.
- the insertion and fixing position of the sheave with respect to the shaft can be changed between the first roller and the second roller.
- the second roller by positioning the shib on the vertical line of the center of gravity, the wire is hooked or the wire is vertically aligned with the entire center of gravity. Can be hung down.
- This method is effective for smoothing the lifting operation of the load.
- the wire When the fixed position of the shaft with respect to the shaft is made different between the first and second rollers, the wire is obliquely stretched between the sheaves. As a result, the wire may be bent when it comes into contact with a part (sheave flange) other than the sheave winding surface (valley), and excessive friction may be applied to that part. However, if cargo handling is performed in this state, the wires may be cut by friction.

- Reference numeral 10 denotes a conventionally known electric winch.
- the electric winch 10 is configured by connecting a drum 3 to a drive shaft 2 of a motor 1 side by side.
- a speed reducer is interposed between the drive shaft 2 and the drum 3 as appropriate.
- Driving an electric motor 1 such as a geared motor
- the drum 3 is rotated, and the wire 4 can be wound around the drum 3 or the wire 4 can be fed from the drum 3.
- a hook 5 for hanging a load is provided at the end of the wire 4.
- a cover frame 11 having the same box structure as that described in the background art is attached to the upper part of the electric winch unit 10.
- the box structure means a box shape in which only the lower surface is opened.
- a front plate 1 2 ′ and a rear plate 13 are fixed to the front and rear of the cover frame 11 by bolt-on. Note that the front and rear plates 12 and 13 do not need to be separate members from the cover frame 11, and the cover frame 11 may be extended.
- a first roller 20 and a second roller 30 are provided between the front and rear plates 12 and 13.
- a weight 6 and a stopper 7 are provided on the distal end side of the wire 4.
- the weight 6 is for applying a load to the wire 4 even in an unloaded state, and is for hanging the wire 4 in the vertical direction while being wound around the first and second rollers 20 and 30.
- the stopper 17 prevents overwinding by making contact with the upper limit lever 8 provided with a limit switch or the like during lifting.
- the weight 6 and the stopper 7 can be used alternately, and the weight 6 and / or the stopper 7 may be omitted.
- the electric winch 10, the cover frame 11, the front and rear plates 1 2 ⁇ 1 3, the first and second rollers 20 ⁇ 30, the weight 6, the stopper 7, the upper limit lever 18, the hook Assume that the entire center of gravity including the weight of 5 is at point A. Since the electric winch 10 having the heaviest weight among them has the motor 1 heavier than the drum 3, the point A of the entire center of gravity in the left-right direction will be closer to 1m.
- a cover hook 11 is provided on the cover frame 11 on the point A of the center of gravity.
- the hook 40 may have another structure such as a ring. In short, it is only necessary that the hoist can be hung, and from this viewpoint, it is also within the scope of the present invention to omit the cover frame 11 and directly provide the hook 40 on the electric winch portion 10 .
- the wire 4 unwound from the drum 3 passes through the lower half of the first roller 20 and is turned to the gravity point A side. After the conversion, the wire 4 is wound down around the upper half of the second roller 30 in a substantially half-wound state, and is turned downward. At this time, the mounting position of the second roller 30 with respect to the front and rear plates 12 and 13 is determined such that the wound wire 4 is vertically below the hook 40. As a result, both the load suspending hook 5 and the hoist suspending hook 40 are positioned on the vertical line at the center A of the center of gravity of the entire hoist.
- the entire hoist is hung using the hooks 40, so that a left-right balance is obtained in an empty state. Even when the load is hung on the hook 5, the hook 5 and the wire 4 are aligned vertically below the hook 40, that is, on the vertical line of the center A of the center of the hoist as a whole, and the left-right balance is still maintained. .
- the weight of the load does not matter.
- a general-purpose electric winch can be used as an electric hoist, and the left-hand balance is always maintained regardless of whether the vehicle is unloaded or lifted. Can be done.
- the hoist according to the second embodiment includes a first 'second roller 20 ⁇ 30 and a cylindrical shaft 21 ⁇ 31 ⁇ a sheave 22 ⁇ 3 ⁇ It consists of.
- the cylindrical shaft 2 1 ⁇ 3 1 is rotatably mounted between the front and rear plates 12 and 13 of the force frame 11.
- the sheaves 2 2 ⁇ 3 2 are formed with valleys 2 4 ⁇ 3 4 for winding the wire between the opposed flanges 2 3 '3 3, and at least one of the flanges 2 3 ⁇ 3 3 has an extension tube 2 outside.
- the first and second rollers 20.30 have the same configuration.
- the sheave 22 is determined as follows by the cylindrical shaft 21 (that is, the sheave 22 can be determined. That is, the sheave 22 is positioned with the wire 14 fed from the drum 3 as a tangent line.
- the sheave 32 of the second roller 30 is positioned on the cylindrical shaft 31 as follows: That is, the wire 14 wound down from the sheave 32 is positioned vertically below the center A of the center of gravity. Then, the sheave 32 is positioned on the cylindrical shaft 31.
- the front and rear positions of the wire 14 wound down from the sheave 32 of the second roller 30 are also vertically below the hook 4, that is, vertically below the center A of gravity of the entire hoist. Therefore, the front and rear balance of the hoist can be measured regardless of whether it is empty or not. Also, there is no movement of the wire 14 due to the sheaves 22 and 32. In addition, since sheaves 2 2 and 32 are fixed by screws 26 and 36, they cannot move on cylindrical shafts 2 and 31. As a result, stable cargo handling work can be performed.
- the wire 4 is obliquely bridged between the two sheaves 2 and 32. Will be.
- the movement of the sheaves 2 2 3 2 on the cylindrical shaft 2 1 3 1 is restricted by screws 26 3 36.
- the wire 4 rubs against one of the sheaves 2 2 and 3 2, particularly one of the flanges 2 3 ⁇ 3 3. If the load is large, the friction also increases, and the wire 14 may be cut.
- the following measures are taken. That is, as shown in FIG. 5, the relationship between the sheaves 2 2 and 3 2 and the wire 4 is adjusted so that the angle between the line connecting the sheaves 2 2 and 3 2 The orientation of the sheaths 22 and 32 is adjusted so that they match the angle of inclination of the wire 14 between the sheaths 22 and 32).
- the cylindrical shaft 2 1 Mounted diagonally with respect to rear plate 1 2 ⁇ 13. The angle is set so as to be orthogonal to the inclination angle of the wire 14 between the sheaves 22 and 32.
- the wire 3 is hung vertically to the valleys 2 4 3 4 of the sheaves 2 2 3 2, so that the wires 1 3 4 does not contact the flanges 2 3 ′ 3 3 of the sheaves 2 2, 3 2, and the wire 4 does not bend or apply excessive force. Therefore, it is possible to avoid cutting the wire due to friction or the like. In addition, since the friction applied to the sheaves 22 and 32 is reduced, the load on the motor 1 can be reduced.
- a wire is a concept including a rope and a chain.
- the term “mo-night” is a concept that includes an electric motor and a geared motor.
- the electric winch when used for the electric hoist, the electric winch can be fixed by the simplest suspension method.
- This suspension method can be implemented in many factories and warehouses without additional equipment.
- the electric winch since the electric winch is suspended, the balance between left and right and front and rear does not collapse. Work can be done.
