Description

  The present invention relates to an apparatus for raising an object to be lifted from a horizontal posture to a vertical posture during a lifting operation.

In the lifting work at the construction work site, there is a case in which the work to be lifted is raised from a horizontal posture to a vertical posture. For example, when lifting a long panel such as a panel as an outer wall or a steel column, the hoist 20 such as a crane or a hoist is used in a state where the lifted objects are horizontally stacked or placed horizontally. As shown in FIG. 8 (a), for this purpose, a lifting jig 2 for lifting the object to be lifted 1 in a horizontal posture and rotating it in a vertical posture in the air is used. Such a hanging jig 2 is generally disclosed in Patent Document 1, for example.
For example, as shown in FIG. 8B, when the work space is small and cannot be raised after being lifted, such as when lifting work is performed near the site boundary, In general, the object 1 is lifted by gradually sliding it while lifting it, but in that case, it is also possible to raise the object while sliding the object to be lifted using an appropriate kind of traveling carriage. For example, Patent Document 2 discloses a traveling vehicle for that purpose.

  However, the former method cannot be applied when the work space cannot be secured, and the latter method is not sufficient because it may become unstable by swinging back and forth greatly at the moment when the lifted object 1 is lifted. Safety measures are essential.

  In view of the above circumstances, an object of the present invention is to provide an effective and appropriate raising device that can be safely and easily raised when lifting an object to be lifted.

The present invention is an apparatus for raising a lifted object from a horizontal position to a vertical position when lifting the lifted object in a vertical posture, with the lifted side facing forward. A rotating gantry that is mounted in a horizontal posture and that can rotate in a vertical plane, and supports the rotating gantry rotatably, and raises the rotating gantry from a horizontal posture to a substantially vertical posture by raising its front side. A rotation guide mechanism for guiding a rotation operation for the rotation guide mechanism, wherein the rotation guide mechanism is configured to guide the rotary mount from a horizontal position to a front portion thereof, and a linear guide member directly above the rotation mount. It is comprised by the curve guide member which guides so that it may descend | fall while sliding the front part forward from the state of an attitude | position, It is characterized by the above-mentioned.
In the raising apparatus of the present invention, the curve guide member in the rotation guide mechanism is constituted by a quarter arc-shaped portion and a horizontal straight line portion connected to the front portion thereof, or the entire curve guide member is formed as a series of elliptic curve shapes. It is conceivable to configure.

  According to the raising apparatus of the present invention, the rotating platform is placed in a horizontal posture, and the object to be lifted is mounted thereon with the suspension head facing forward, and the object to be lifted is gradually added by a crane, a hoist, or the like. The lifting platform is guided by the rotation guide mechanism and smoothly rotates while sliding forward, so that the lifted object can be lifted up easily and safely. it can. Therefore, a series of lifting operations of raising and lifting the object to be lifted as it is can be performed easily and safely only by operating the lifting machine, and it is not necessary to secure a special working space. It can be carried out without any trouble even in a small work space of the same degree, and can contribute to an improvement in the efficiency of the lifting work.

According to the raising device of the present invention, the front part of the rotating gantry is guided by the linear guide member, and the rear part of the rotating gantry is guided by the curved guide member. The position of the center of gravity does not greatly move up and down, so that it can be raised up easily and safely.
In particular, by configuring the curved guide member with a quarter arc-shaped part and a horizontal straight line part connected to the front part thereof, it is possible to stand up by itself using the weight of the lifted object at the initial stage of raising, Alternatively, by making the curved guide member an appropriate elliptic curve, the vertical movement of the center of gravity position is completely eliminated, and a substantially weightless raising operation is possible.

  1 to 5 show a raising apparatus according to an embodiment of the present invention. This is because, for example, when a flat plate-like object 1 such as an outer wall panel is lifted, the object 1 is lifted almost directly below the suspension point in order to raise the object 1 from the horizontal position to the vertical position at the lifting position. As shown in FIG. 1, the rotary frame is mounted on the left and right main frames 3 and can be rotated in a vertical plane by mounting the object to be lifted 1. 4 and a rotation guide mechanism 10 that supports a rotation operation in a vertical plane while supporting the rotary mount 4.

  The rotary mount 4 is a flat plate having a size capable of mounting the entire object 1 to be lifted, and has main beams 5 made of steel such as H-shaped steel on both sides thereof. The front part and the rear part of the beam 5 are supported by the above-mentioned rotation guide mechanism 10 via the front support mechanism 6 and the rear support mechanism 7 at only four points in total. It is guided by the mechanism 10 and is rotatable in the vertical plane so that its posture can be freely changed. It should be noted that a stopper 8 is provided at the rear portion of the rotating gantry 4 so as to prevent the lifted object 1 from falling off during the raising operation.

  The rotation guide mechanism 10 includes a vertical linear guide member 11 that supports and guides the front portion of the rotating gantry 4 and a curved guide member 12 that supports and guides the rear portion of the rotating gantry 4. It is comprised from the circular-arc-shaped part 12a and the horizontal linear part 12b continuing to the front part.

As shown in FIG. 3, the linear guide member 11 in the present embodiment is made of a steel material such as a grooved steel having a C-shaped cross section with the groove portion 11a facing inward, and the groove portion 11a includes the main beam 5 of the rotary mount 4. The front support mechanism 6 provided at the front of the slidably engages in a slidable and non-detachable state.
As the front support mechanism 6 in this embodiment, a rotatable roller is employed, and the roller rotates freely by sliding in the vertical direction in the groove 11a while freely rotating in the groove 11a of the linear guide member 11. The front portion of the gantry 4 is smoothly guided in the vertical direction along the linear guide member 11.
In the present embodiment, only the upper half of the steel material such as channel steel functions as the linear guide member 11, and the lower half thereof is an extension 11 b that extends the linear guide member 11 downward as it is. An upper stopper 13 is provided near the upper end of the extension 11b (that is, near the lower end of the original linear guide member 11) for locking the rotary mount 4 in a horizontal position. Also, the lower end of the extension 11b is connected to the tip of the horizontal straight portion 12b of the curved guide member 12, and a lower stopper 14 for locking the rotary mount 4 in a vertical posture is provided there. Yes.

On the other hand, the curved guide member 12 in the present embodiment is made of a steel material such as cut tee steel as shown in FIG. 4, and is provided at the rear portion of the main beam 4 of the rotary mount 4 with respect to the curved guide member 12. The rear support mechanism 7 is engaged in a slidable and non-detachable state.
As the rear support mechanism 7 in the present embodiment, the left and right sliding members 15 that slide along the web 12c while sandwiching the web 12c of the curved guide member 12 from the front and the back, and the sliding while abutting on the leading edge of the web 12c. The upper and lower sliding members 16 are made up of. As these sliding members 15, 16, resin molded products having a small sliding resistance and excellent durability can be suitably employed, both of which are directly or appropriately applied to the surface of the mounting base 17 attached to the main beam 5. It is good to attach through the mounting tool 18 so that replacement | exchange is possible.

The raising device having the above-described configuration is used by being placed at the lifting position (the position of the linear guide member 11 is the lifting start position) when performing the lifting work.
As shown schematically in FIG. 5, the operation of raising the lifted object 1 using this raising device is such that the lifted object 1 is directed forward on the rotary mount 4 in a horizontal posture. After being mounted in a state, it is carried out by hanging the to-be-lifted object 1 gradually by performing slinging with a lifting machine 20 such as a crane or a hoist. In addition, you may make it add operation which pushes down the rear part of the to-be-lifted object 1 thru | or the rotary mount 4 at the time of a lifting start.
As a result, as indicated by the arrows in the figure, the rotating gantry 4 is guided by the rotation guide mechanism 10 and smoothly stands up while sliding forward, more strictly, the front portion of the rotating gantry 4 Since the rear part descends and moves forward at the same time as it rises directly above, the lifted object 1 mounted on the rotating gantry 4 has a vertical posture in which it rises along the straight guide member 11 from the horizontal posture. Can be lifted up easily and can be lifted safely as it is.

  Therefore, according to the raising apparatus of the present embodiment, a series of lifting operations of raising the object 1 and lifting it as it is can be carried out very simply and safely only by operating the lifting machine 20. It is not necessary to secure the work space, so that it can be carried out without any trouble even in a work space that is as narrow as the conventional one, and can contribute to the improvement of the efficiency of the lifting work.

  Moreover, when the lifted object 1 is erected, the lifted object 1 rotates while sliding forward as described above, and the center of gravity G of the lifted object 1 at that time is shown in FIG. As shown in FIGS. 2 and 5, the weight of the lifted object 1 starts to rise and then rises. Therefore, in the initial stage of raising, the lifted object 1 naturally rises due to its own weight. There is also an advantage that it is not necessary.

  Although one embodiment of the present invention has been described above, the above embodiment is merely a preferred example, and the present invention is not limited to the above embodiment. For example, various designs such as those listed below can be used. Changes and applications are possible.

  The above embodiment is an example in the case of assuming a flat panel shape such as an outer wall panel or the like as the object to be lifted 1, and thus a flat plate mount 4 on which it can be mounted is adopted. The shape and dimensions of the lifted object 1 may be appropriately changed in consideration of the size, shape, weight, and other conditions of the object 1 to be lifted, and the rotation guide for guiding the rotation while supporting the rotating mount 4 accordingly. The configurations of the mechanism 10, the front support mechanism 6 and the rear support mechanism 7 that respectively support the front and rear portions of the rotary mount 4, the cross-sectional shapes of the linear guide member 11 and the curved guide member 12, and the like can be variously changed.

For example, in the above embodiment, a roller is used as the front support mechanism 6, but an appropriate sliding member can be used as the front support mechanism 6 as in the case of the rear support mechanism 7.
In the above embodiment, the sliding members 15 and 16 are used as the rear support mechanism 7 as shown in FIG. 4, but as another configuration example of the rear support mechanism 7, a curved guide as shown in FIG. It is also conceivable to form a pair of rollers 21 that sandwich the web 12c of the member 12 from the front and back, and a roller 22 that rolls the leading edge of the web 12c. However, in this case, since the angle with respect to the curved guide member 12 changes at each position due to the rotation of the rotating gantry 4, the roller 21 may be attached to the main beam 5 so as to be displaceable via an appropriate suspension mechanism. Preferably, each roller 21 is naturally displaced with the rotation of the rotating gantry 4 so that the curved guide member 12 can be stably held at an appropriate position.
In any case, the front support mechanism 6 and the rear support mechanism 7 need to slide smoothly with respect to the linear guide member 11 and the curved guide member 12, but in addition, in some cases It is conceivable to add an appropriate sliding resistance or to add a mechanism for restraining and fixing the rotation of the rotary mount 4 at an arbitrary position, which causes the rotary mount 4 to rotate carelessly. This can be prevented and more stable and safe work can be performed.

Moreover, in the said embodiment, although the curve guide member 12 was comprised by the quarter-arc-shaped part 12a and the horizontal linear part 12b, the curve shape of the curve guide member 12 is not limited to it, In short, the linear guide member 11 and As long as the rotary frame 4 can be erected while sliding forward, the curved guide member 12 can adopt an arbitrary curved shape as long as it is, for example, schematically shown in FIG. It is also conceivable that the curved guide member 12 is constituted by a single elliptic curve as shown.
In the case where the curved guide member 12 is an elliptic curve, if the curvature is designed as a relationship of major axis radius: minor axis radius = 2: 1, in principle, the center of gravity position G associated with the raising is illustrated. As shown in the figure, the object to be lifted 1 can be lifted up without weight, except that it moves horizontally forward and does not move up and down. This can be performed more easily. Of course, if an appropriate elliptical curve or an arbitrary curve is set, the weight of the lifted object 1 is raised using the weight of the lifted object 1 as in the case of the above-described embodiment (that is, the lifted object rises itself by its own weight). It is also possible to configure as described above.

  In addition, if the to-be-lifted object 1 is mounted on the rotary mount 4 as in the above-described embodiment, if the crane 1 is hung on the lifting machine 20 such as a crane or a hoist, the raising and lifting are performed only by operating the lifting machine 20. However, the erection operation is performed by using other appropriate equipment or instruments or by manual operation of an operator, raising the object to be lifted 1 and then slapping it. Of course, it is also possible to start lifting.
