  FIG. 1 is an explanatory view showing a lifting operation of a drum type washing machine by the lift device of the present embodiment.

  In FIG. 1, the lift device 10 of the present embodiment supports a fork 18 in a cantilevered manner in a cantilevered manner by a slider 16 in front of a guide frame 14 erected on a carriage 12, and is set on the drum type washing machine 40 side. The fork 18 is inserted under the gantry 30 and lifted up.

  Two belt strings 32 are passed over the gantry 30, and a hook member 34 attached to the ends of the strings hanging on both sides is used for lifting work formed on the side surface of the drum type washing machine 40. A hook claw portion is hooked on and engaged with the recess 35 for insertion, and the drum-type washing machine 40 is lifted by raising the pedestal 30 by the fork 18, and a spacer block 44 is placed thereunder. .

  FIG. 2 is an explanatory view showing an embodiment of a lift device used in the present embodiment. FIG. 3 is a front view thereof, and FIG. 4 is a plan view thereof.

  In FIG. 2, the lift device 10 of the present embodiment has a guide frame 14 standing on a carriage 12, and the height of the guide frame 14 is about 180 cm. A fork 18 is supported by a slider 16 in a cantilevered manner in front of the guide frame 14.

  As shown in FIG. 3, an actuator 20 driven by air pressure or hydraulic pressure is provided below the guide frame 14, and a rod 21 taken out from the upper portion of the actuator 20 is connected to the slider 16. The actuator 20 is a piston cylinder mechanism, which generates hydraulic pressure by stepping on a foot pedal 22 on the carriage 12 shown in FIG. 2, supplies hydraulic pressure to the cylinder chamber of the hydraulic actuator 20 and pushes up the piston, whereby the rod 21 Thus, the slider 16 can be driven up.

  Here, the distance between the bogie 12 and the front wheel overhanging the fork 18 is as short as L1, and the distance L2 up to the wheel of the bogie 12 on the rear side is increased. When the distance L1 to the front wheel with respect to the guide frame is shortened, the lift device 10 is set in the washing machine storage place, which will be clarified later, and the fork 18 is placed inside the washing machine storage place. The carriage 12 does not get in the way.

  FIG. 5 is an explanatory view showing a belt strap with a hook and a base used in the embodiment of FIG. 1, in which FIG. 5 (A) shows a plan view and FIG. 5 (B) shows a side view.

  In FIG. 5, the pedestal 30 uses a steel plate having a thickness of several millimeters, and a plurality of cutouts 58 are formed in order to reduce the weight.

  Height adjustment bolts 50 are attached to the four corners of the gantry 30, and as shown in FIG. 1, the gantry 30 becomes substantially horizontal when placed on the drum type washing machine 40 during suspension. So that the height is adjusted. A rubber cap 51 is attached to the lower end of the height adjustment bolt 50.

  This is because the upper surface of the drum-type washing machine to be lifted is not necessarily flat, for example, there are various shapes such as the front of the washing machine being rounded and lowered, and the pedestal 30 is arranged horizontally in accordance with this. The height adjusting bolt 50 is provided so that it can do.

  A handle 52 is attached to both ends of the upper surface of the gantry 30, and the gantry 30 is placed on the washing machine with the handle 52. Two belt strings 32 are passed through the gantry 30, both ends are suspended downward, and a hook member 34 is attached to the tip. The position of the belt string 32 passing over the gantry 30 is determined by a positioning band 54. The positioning band 50 is a cloth band, and a ring that can be freely opened and closed is formed by Velcro (R) or the like so that the belt string 32 can be easily attached and detached.

  The belt string 32 is a string member knitted by reinforcing fibers reinforced against tensile tension, and is connected in a loop shape by a buckle 56, and is suspended from both ends of the loop through hook members 34 on both sides. The length of the belt string 32 is sufficient to suspend the drum-type washing machine 40 as shown in FIG.

  FIG. 6 shows the frame shown in FIG. 5 taken out. FIG. 6A is a plan view, FIG. 6B is a side view, and FIG. 6C is a front view. From FIG. 6, the ring of the positioning belt 54 through which the handle 52 provided on the gantry 30 and the belt string 32 pass is apparent.

  FIG. 7 shows the belt string 32 of FIG. 5 taken out, and FIG. 7A is a plane, and FIG. 7B is a side surface. With one end fixed to the buckle 56, the belt string 32 passes through the hook members 34 positioned at both ends, and then is connected in a loop through the buckle 56 and overlapped. By using such a double belt string, a sufficient strength can be secured even when a drum type washing machine having a weight close to 100 kg is lifted.

  Note that, as in the present embodiment, the belt string may be combined into a loop shape so as not to be doubled, but may be a single belt string in which a ring having a hook member 34 is formed at both ends.

  8A and 8B are explanatory views showing the hook member passing through the belt strap of FIG. 7, with the front shown in FIG. 8A and the back shown in FIG. 8B. FIG. 9A shows a side surface and a cross section of the hook member.

  8 and 9, the hook member 34 has a belt through hole 62 formed in the upper part of a steel plate hook plate 60, and a bearing part 64 having an axial center line in the vertical direction is fixed to the lower part by a weld fixing part 84. ing. A hook claw 66 is rotatably attached to the bearing portion 64. The hook claw 66 has a shaft portion 68 and an engaging portion 70. The shaft portion 68 is rotatably fitted into the bearing portion 64, and a stopper 74 is integrally formed at the tip, on which a first spring is locked. The pin 76 is integrally formed.

  The engaging portion 70 of the hook claw 66 is formed to bend obliquely upward from the lower side of the shaft portion 68, and its length is a length that matches the depth of the concave portion 35 formed on the side surface of the washing machine, Further, a rubber tube 72 is attached to prevent slippage and damage when the rubber tube 72 is engaged with the recess 35 on the side of the washing machine.

  On the hook plate 60 on both sides with respect to the first spring locking pin 76 formed at the tip of the shaft portion 68 of the hook claw 66, the second spring locking pin 78 is fixed. A coil spring 80 is mounted between the second spring locking pins 78 to constitute a centering mechanism for centering so that the engaging portion 68 of the hook claw 66 is directed in a direction (washing machine side) perpendicular to the inside of the plate. .

  Here, the hook claw 66 can be freely rotated in the left-right direction against the pair of coil springs 80 provided in the centering mechanism. However, when the hook claw 66 is rotated, the first spring is locked. The pin 76 also rotates to wind the coil spring 80, and the coil spring 80 hits the hook plate 60 and interferes with this winding. Therefore, in order to avoid the interference of the coil spring 80, a rectangular opening 82 is formed in the portion of the hook plate 60 facing the first spring locking pin 76.

  A magnet plate 65 is mounted on the inner surface side of the hook plate 60 and the washing machine casing is made of a thin steel plate, so that the hook plate 60 can be attracted and held in a recess on the side surface of the washing machine. The magnet plate 65 only needs to attract the hook plate 60 to the side surface of the washing machine, and may be a weak magnet so that the hook plate 60 can be easily removed from the side surface of the washing machine.

  Here, when the hook claw 66 is rotated 90 ° from the centering position as shown in FIGS. 10B and 10C, the thickness L3 of the hook member 34 is equal to the thickness of the hook plate 60 and the outside of the bearing portion 64. The thickness is a thickness to which the diameter is added, and this thickness L3 determines the gap between the washing machine in which the hook member 34 can be set and the wall. In the present embodiment, the thickness L3 of the hook member 34 does not exceed 10 millimeters. As a result, if the clearance between the washing machine and the wall is 10 millimeters or more, the hook is placed in the recess on the side surface of the washing machine. The member 34 can be set.

  FIG. 10 shows the centering mechanism by the plane of the hook member of FIG. 8 and its cross section, and it can be seen that the interference of the coil spring accompanying the rotation of the hook claw is avoided by forming the opening.

  FIG. 10A shows a state in which no external force is applied to the hook claw 66, and the hook claw 66 is centered by the force of the pair of coil springs 80, and the engaging portion 66 is oriented in the back direction perpendicular to the hook plate 60. Hold on.

  FIG. 10B shows a state where an external force is applied to the hook claw 66 and it is turned 90 degrees to the left from the centering position 66a. As the hook claw 66 turns, the first spring locking pin 76 also turns, 80 is wound clockwise. At this time, if there is no opening 82 in the hook plate 60, interference occurs that a part of one of the coil springs 80 is crushed against the hook plate 60, but the hook claw is formed by forming the opening 82. Interference of the coil spring 80 is avoided along with the rotation of 66, and if the external force is released, the hook pawl 66 can be smoothly returned to the centering position of FIG.

  FIG. 10C shows a state where an external force is applied to the hook claw 66 and it is turned 90 degrees to the right from the centering position 66a. Similarly, the interference of the coil spring 80 due to the rotation of the hook claw 66 is caused by the formation of the opening 82. If it is avoided and the external force is released, the hook claw 66 can be smoothly returned to the centering position of FIG.

  As a spring member of the centering mechanism for returning the hook claw 66 to the centering position, in addition to the pair of coil springs 80 of the present embodiment, when the left and right rotation by the external force is released, the hook claw 66 is appropriately returned to the centering position. The spring mechanism can be applied.

  FIG. 11 is an explanatory view showing a hook mounting jig used in the present embodiment, and FIG. 12 shows suction holding of a hook member by the hook mounting jig of FIG.

  The hook member 34 attached to the tip of the belt string 32 used in the present embodiment must be engaged with a concave portion on the side surface of the drum-type washing machine to be lifted through a narrow gap between the wall and Since no hands are required, the hook mounting jig 86 of FIG. 11 is used.

  The hook mounting jig 86 is provided with a gripping portion 88 held by one end of the rod 90, and a magnet 92 is mounted on the other end of the rod 90. As the magnet 92, a neo magnet or the like that generates a strong magnetic force while being small in size is used.

  When the hook member 34 is set in the recess on the side surface of the washing machine through a gap with the wall, the front side of the hook plate 34 of the hook member 34 is moved by the magnet 92 at the tip of the hook mounting jig 86 as shown in FIG. Hold it by suction and insert it into the gap in this state.

  Next, the hanging operation of the drum type washing machine by the lift device of this embodiment will be described. FIG. 13 is an explanatory diagram showing a storage state of the drum type washing machine as a work target of the present embodiment.

  In FIG. 13, a washing machine storage place 36 provided in a kitchen of an apartment house such as an apartment has a waterproof pan 38 on the floor surface, and a drum type washing machine 40 is installed on the waterproof pan 38. Since the drum type washing machine 40 is integrally provided with a dryer, it usually has a weight of 80 kg to 100 kg.

  In this stored state, the gap 94 with the side wall of the drum type washing machine 40 is not usually a sufficient gap for human hands to enter, and there is only a gap of about 10 mm depending on the location. There is also.

  FIG. 14 is an explanatory view showing a preparatory work for setting a frame through which a belt string is passed through a drum type washing machine. In this preparatory work, the pedestal 30 through which the two belt strings 32 to which the hook members 34 are attached is placed and set on the drum type washing machine 40 to be worked. At this time, the height is adjusted by the height adjusting bolt 50 so that a sufficient clearance for the fork of the lift device 10 to enter between the gantry 30 and the upper part of the washing machine is secured, and at the same time, the gantry 30 is substantially horizontal. .

  Subsequently, the hook member 34 attached to the tip of the belt string 32 is attracted to the magnet at the tip of the hook attaching jig 86 and is inserted into the gap between the side surface of the washing machine and the wall. At this time, the hook claw 66 that is centered and protrudes toward the washing machine side of the hook member 34 rotates against the washing machine side when the gap is narrow, and as a result, the gap is the hook plate shown in FIG. If it is more than thickness L3 by 30 and the bearing part 68, it can insert in a clearance gap.

  Here, the thickness L3 by the hook plate 30 and the bearing portion 68 shown in FIG. 10 (A) is L3 = 10 millimeters. Therefore, if the gap dimension is 10 millimeters or more, the hook member 34 is set in the washing machine. Can do.

  When the hook member 34 is inserted into the gap between the side surface of the washing machine adsorbed by the magnet at the tip of the hook mounting jig 86 and the wall, an external force is applied to the hook claw 66 that has been rotated at the position of the recess 35 on the side surface of the washing machine. The hook claw 66 returns to the centering position by the force of the coil spring 80, and the hook claw 66 automatically engages with the recess 35 on the side surface of the washing machine.

  When the hook member 34 is pressed against the washing machine in this state, as shown in FIG. 8B, the hook member 34 is attracted and held on the side of the washing machine by the magnet plate 65 attached to the hook plate 60. In this state, even if the hook mounting jig 86 is turned to remove the adsorption of the magnet at the tip, the hook member 34 is held in a state where the hook claw 66 is engaged with the recess 35 on the side surface of the washing machine.

  Preparation is completed by performing the operation of engaging the recess 35 on the side surface of the washing machine of the hook member 34 using such a hook mounting jig 86 at four locations.

  Subsequently, as shown in FIG. 15, the lift device 10 of the present embodiment is moved to the washing machine storage place 36, and the front wheel of the carriage 12 hits the waterproof pan 38 with the fork 18 positioned below the gantry 30. Press to the position. Subsequently, with respect to the carriage 12, the lock lever provided on the wheel is set at the lock position so as not to move.

  If necessary, an operator puts his / her foot on the carriage 12 to prevent it from shifting backward, and when lifting the drum-type washing machine 40, the operator puts weight on the carriage 12 so that the guide frame 14 does not fall down. The guide frame 14 is supported by hand.

  Furthermore, since the floor surface of the washing machine storage place 36 in the house may not be sufficient in strength, in such a case, a reinforcing plate is laid in advance at the position of the carriage 12 of the lift device 10 and the carriage is placed thereon. Work with 12 on.

  Subsequently, when an operator repeatedly presses the stepping handle 22 while holding the handhold handle 26 by hand to support the carriage 12 so as not to move backward, air pressure or hydraulic pressure is supplied to the actuator 20 shown in FIG. As shown, the fork 18 is raised by the slider 16 to lift the gantry 30, and the drum type washing machine 40 can be lifted by the hook members 34 of the two belt strings 32 passing through the gantry 30.

  At this time, since the drum-type washing machine 40 is lifted at four points by the hook member 34, if the center of gravity of the washing machine is within the lifting range of the four points, the drum-type washing machine 40 can be lifted safely while maintaining the same posture without tilting. be able to.

  When the drum-type washing machine 40 is lifted by the lift device 10, the spacer blocks 44 prepared in advance are arranged at the four corners in the gap formed between the waterproof pan 38 and the arrangement of the spacer blocks 44 is completed. Then, the slider 16 is driven to descend by pulling the lowering valve lever 24 forward, and the fork 18 is lowered, and the drum type washing machine 40 is placed on the spacer blocks 44 installed at the four corners of the waterproof pan 38.

  If the drum-type washing machine 40 is placed on the spacer block 44, the fork 18 is further lowered, and then the carriage 12 is moved backward to extract the fork 18 from under the gantry 30.

  With respect to the hook member 34 set in the recess 35 on the side surface of the washing machine, when the rack 30 is lowered from the upper part of the wash and the belt strap 34 is pulled forward, the magnet plate attracts the hook member 34 to the side surface of the washing machine so strongly. Therefore, the hook member 34 can be easily removed.

  In actual work, a plurality of racks 30 through which the hooked belt string 32 shown in FIG. 5 was passed were prepared, and the belt string 32 was passed through the washing machine of the dwelling unit to be worked. The work efficiency for a large number of dwelling units such as a condominium can be increased by preceding the work of setting the gantry 30 and performing the lift work using the lift device 10 later.

  FIG. 16 is an explanatory view showing an installation state of the washing machine after lifting the drum type washing machine and completing the arrangement of the spacer block. In FIG. 16, the spacer block 44 is arranged at the four corners on the waterproof pan 38 using the lift device of the present embodiment, and the drum type washing machine 40 is put on the spacer block 44.

  The waterproof pan 38 has, for example, a drain outlet 45 at the center, and the drain outlet 45 is connected to a drain pipe 46. By inserting a drain hose of the drum type washing machine 40 into the drain outlet 45, the washing drain is drained from the drain pipe 46. Can be discharged. The position of the drain outlet varies depending on the type of waterproof pan.

  A laundry drain trap 48 is accommodated in the drain port 45 to remove dust and dirt contained in the washing water so that it does not flow into the drain pipe 46.

  The washing machine storage place 36 is installed as a space corresponding to the size of the drum type washing machine 40, and with the drum type washing machine 40 installed, the gap between both sides and the back wall is narrow enough to allow human hands to enter. It is a gap, and the drum type washing machine 40 can be arranged with good appearance in terms of furniture in a state where it is installed in the washing machine storage place 36.

  The spacer block 44 forms a gap L between the waterproof pan 38 and the drum type washing machine 40, and the gap L is used to take out the washing drain trap 48 stored in the drain 45 of the waterproof pan 38 to the outside. There are enough gaps.

  For example, since the height of the laundry drainage trap 48 is about 80 mm, the gap L by the spacer block 44 is set to L = 110 mm, for example, and at least the gap L needs to be 100 mm. This gap L is a space sufficient to put a washing hose into the drainage port 45 of the waterproof pan 38 and perform the washing operation of the drainage pipe 46.
