Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hoisting tool used for hoisting an object to be hoisted, particularly a B beam.

[0002]

[Prior Art]

 Generally, when loading B-beams or other members transported from the factory to a predetermined position by unloading them from trucks, workers on the site usually install wires, antok lamps, sling belts, etc. at both ends of the B-beams. After hanging, it is slung by a crane and lifted. Then, after the B beam is installed at a predetermined position, the work of removing the wire, the ant clamp, the sling belt, or the like from the B beam is performed.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional wire or ant clamp lifting equipment, if lateral shake occurs due to wind during lifting, the lifting equipment must be securely tightened and fixed to the B beam. There was a risk that the fixed position would be displaced, and the B beam would fall off the suspension and fall. In addition, the B-beam is formed in a V shape when viewed from the side, and when the lifting device is fixed and hoisted at two places on the right and left at an appropriate distance from the center of the B beam, There was a possibility that the left and right hoists slid toward the center of the B beam along the inclined bottom surface of the B beam, and the hoisting angle changed.

In addition, the work of removing the wire from the B beam must necessarily be performed at a high place such as a shed assembly part of a building, and a skilled worker rides on the shed assembly part to perform this work. It is usual to carry out the work, and thus the work of removing the wire from the B beam has a poor workability.

The present invention has been made in view of the above circumstances, and provides a hoisting tool that does not shift the locking position when hoisting an object to be hoisted, particularly a B beam or the like. It is an object.

[0008]

[Action]

 According to the hoisting tool of the present invention, a hanging object such as a B-beam is placed between the side surface supporting parts of the hoisting device so as to be placed on the bottom surface supporting part. Then, the tubular member is moved downward until the lower surface of the engaging member comes into contact with the upper surface of the B beam while being pressed, and the tubular member is fixed at that position by the positioning portion. As a result, the object to be lifted is sandwiched between the bottom surface support portion and the engaging member, and the locking position of the lifting tool does not move. Then, the hoisting rope connected to a crane or the like is lifted, and the B beam is hoisted and installed on the roof.

Further, after the B-beam is hung up and installed on the roof part of the house, the lifting tool is removed from the B-beam. At this time, by pulling the string-shaped operation part from the ground, the fixation of the tubular member by the positioning part is released. Then, when the hanger is moved downward, the upper surface of the B beam pushes the engaging member upward. In this state, the hanging tool is moved in parallel with the direction of the one side support member to remove the hanging tool from the B beam. As described above, the suspender can be removed from the B beam by operating from the ground.

It is an engaging member 5a that engages with the upper surface 3c of the B beam 3. Further, the tubular member 2 is provided with a positioning portion 2a (shown in FIG. 2) for positioning and fixing the tubular member 2 on the side surface supporting member 4b.

As shown in FIGS. 1 and 2, the tubular member 2 is made of iron and has a rectangular tubular shape. The distance between the left and right facing inner surfaces 2b, 2b of the tubular member 2 is slightly larger than the width of the square steel pipe forming the side surface supporting member 4b. Then, in a state where the tubular member 2 is externally inserted into the side surface support member 4b, the opposing inner surfaces 2b and 2b are guided by the side surface of the side surface support member 4b and can move up and down. Further, the distance between the inner surfaces 2c, 2c facing each other in the front-rear direction of the tubular member 2 is configured to be longer than the thickness of the square steel pipe forming the side surface support member 4b.

The rear side surface 2d of the tubular member 2 is provided with through holes 2e and 2e which are vertically arranged, and a slit 2f which is vertically long is provided between the through holes 2e and 2e. Has been. A pressing lever 2g, which will be described later, is freely rotatable on the right and left sides of the slit 2f on the rear side surface 2d of the tubular member 2 within a plane perpendicular to the rear side surface 2d of the tubular member 2. The flange portions 2h and 2h for supporting are provided so as to project.

The tubular member 2 is provided with the positioning portion 2a as described above. The positioning portion 2a presses the brake plate 2i arranged between the rear inner surface 2c of the tubular member 2 and the rear side surface of the side surface support member 4b and the outer brake plate 2i toward the side surface support member 4b. The pressing lever 2g is mainly configured.

In the braking plate 2i, a non-slip member 2k such as a synthetic resin plate having a high friction coefficient, a synthetic rubber plate, or a natural rubber plate is attached to the side surface of the rectangular iron plate 2j on the side surface supporting member 4b side. is there. Further, on the side surface opposite to the side surface on which the anti-slip member 2k is attached, there are provided cylindrical guide rods 21 and 2l which are inserted into the through holes 2e and 2e of the cylindrical member with respect to the iron plate 2j. Two protrusions are formed at a right angle. A coil spring 2m, which is sandwiched between the side surface of the iron plate 2j and the inner surface 2c of the tubular member 2 and biases the braking plate 2i toward the side surface supporting member 4b, is externally fitted to the guide rods 21 and 2l. There is.

The tip end of the pressing lever 2g is sandwiched between the flange portions 2h and 2h of the tubular member 2 and is rotatably connected to the pin 2n. The tip of the pressing lever 2g is a cam 2p, and the distance from the pin 2n connecting position to the pressing lever 2g tip 2q is the side of the cam 2p where the pressing lever 2g bulges from the pin 2n connecting position. It is formed longer than the distance to the apex 2r of the edge. The side edge of the cam 2p is formed in a curved shape so that the pressing lever 2g can be smoothly rotated in a state where the side edge of the cam 2p is in contact with the braking plate 2i.

Then, based on such a configuration, with the pressing lever 2g in a substantially horizontal state, the tip 2g thereof protrudes from the slit 2f of the tubular member 2 to the inside of the tubular member 2 for braking. The plate 2i is pressed against the side surface of the side surface supporting member 4b to fix the tubular member 2 on the side surface supporting member 4b so as not to move up and down. The fixing is released with the rear end of the pressing lever 2g facing upward.

One end of a string-shaped operating portion 2s is connected to the rear end of the pressing lever 2g so that the fixing of the tubular member 2 by the positioning portion 2a can be released from above the ground. As shown in FIG. 1, the operating portion 2s is arranged so as to hang downward while being wound around a pulley 4h above the side surface supporting member 4b. Then, based on such a configuration, by pulling the other end side of the operation portion downward, the rear end of the pressing lever 2g is pulled up, and the fixing of the positioning portion 2a is released.

The engagement member 5a is a rod-shaped shaft portion 5b extending in a horizontal direction from the front side surface of the tubular member 2 along the bottom surface support member 4a, and is rotatable about the shaft portion 5b. It is composed of a thin plate-like engagement plate 5c supported by the shaft portion 5b. On the upper surface of the engagement plate 5c, three projecting portions 5d having a through hole (not shown) through which the shaft portion 5b penetrates are provided in a line in the longitudinal direction of the engaging plate, and the projecting portions 5d are provided in the shaft portion. It is externally rotatably attached to 5b. A large number of conical claws (not shown) are provided on the lower surface of the engaging plate 5c, and the claws are slightly inserted into the upper surface 3c of the B beam 3 so that the engaging plate 5c is on the B beam 3 above. It is adapted to engage the surface 3c.

In this embodiment, as shown in FIG. 3, two suspenders 1 are used, and the upper portions of the two ropes 6 connected to the respective suspenders 1 are gathered together to form a crane or the like. It is designed to be hooked on a hook (not shown). Further, the two suspenders 1 are adapted to hang on the right and left two places of the B beam 3.

Next, a usage method and an operation of the hanging tool 1 of this embodiment will be described. Here, the B beam 3 as the object to be hung is a beam material mainly used for a roof of a ridge, and as shown in FIG. 3, a substantially rectangular plate-shaped upper plate-shaped body 3d and a substantially rectangular plate-shaped body. A plate-like lower plate-like body 3e is joined by abutting its ends so that they have a predetermined angle to each other, and the joints of both are reinforced by reinforcing plates 3f, 3f from both sides. Is to have. Since the length of the upper plate-like body 3d is usually set shorter than the length of the lower plate-like body 3e, the center of gravity thereof is difficult to set and the left and right sides have uneven load shapes. The B-beam 3 is usually used by being arranged in the back of a shed roof with the upper plate-like body 3d horizontally arranged.

First, the suspenders 1 are attached to the B-beams 3 having the above-described configuration transported from the factory to the site at appropriate distances from the center to the left and right. At this time, the angle of the B beam 3 should be as close as possible to the angle at which the B beam 3 is installed so that the B beam 3 can be lifted. At this time, the method of attaching the hanging tool 1 is as follows. First, with the restricting portion 5 raised to the upper portion of the side surface supporting member 4b, lift the hanging tool from the end of the B beam 3 between the side surface supporting members 4b and 4c. Insert it so that B beam 3 passes through it. At this time, since the braking plate 2i of the positioning portion 2a is biased toward the side surface support member 4b by the coil springs 2m and 2m, the regulating portion 5 does not slip down.

Next, the restriction portion 5 is moved downward. At this time, since the braking plate 2i is only urged by the coil springs 2m and 2m, it can be moved by pressing it downward with a hand. Then, the engaging plate 5c of the restricting portion 5 is tilted according to the tilt of the upper surface 3c of the B beam 3, and the claw on the lower surface of the engaging plate 3c is slightly dented into the upper surface of the B beam 3 until a tubular member is formed. With 2 being pressed downward, the pressing lever 2g is pulled down substantially horizontally. By pulling down the pressing lever 2g substantially horizontally, the tip of the pressing lever 2g presses the braking plate 2i toward the side surface supporting member 4b, and the tubular member 2 is fixed. Therefore, the upper surface 3c of the B beam 3 is engaged with the engagement plate 5c and is sandwiched between the bottom surface support member 4a and the engagement plate 5c.

In this state, the hoisting rope 6 is hoisted by a crane hook or the like, so that the B-beam 3 is hoisted to the installation position of the B-beam 3. At this time, since the two suspenders 1 are lifted from one point, the locking portion 4d of the suspender 1 is inclined in the hook direction, but the engaging plate 5c is rotatable, so The engaging plate 5c corresponds to the inclination of the tool 1, and the engagement between the engaging plate 5c and the upper surface 3c of the B beam 3 is not disengaged. Then, the B-beam 3 is installed or temporarily installed while the B-beam 3 is being lifted.

Next, from the ground side, the string-like operation portion 2s is pulled downward to release the fixation of the tubular member 2. Then, the suspender 1 is moved slightly downward. At this time, the control section 5 that has been released from the fixing state is in a state of being pressed upward by the upper surface of the B beam 3 that is installed and fixed in position, and the control section 5 moves upward with respect to the side surface support member 4b. Moving. Next, when the hanger 1 is slightly moved downward, the engagement between the engagement plate 5c and the upper surface 3c of the B beam 3 is released. In this state, by horizontally moving the sling 1 backward, the B beam 3 can be brought out of the sling 1 from above the side support member 4c, and the sling 1 can be completely removed from the B beam 3. To be done.

As can be easily understood from the above description, according to the hanging tool 1 of the present embodiment, the bottom surface of the B beam 3 is brought into contact with the bottom surface supporting member 4a of the hanging tool 1 so as to be held from below. Both side surfaces 3a and 3c of the B beam 3 are sandwiched between the side surface support members 4b and 4c, and the B beam is sandwiched between the bottom surface support member 4a and the engagement plate 5c. Since the claws of the engaging plate 5c are slightly bited into the upper surface of the B beam 3 to restrict the movement of the B beam 3, the B beam 3 can be firmly fixed even if lateral shake occurs due to wind or the like during lifting. Can be held and protected from this lateral shake.

Similarly, the suspending tool 1 does not slide and move to the center side of the B beam 3 along the inclination of the bottom side of the B beam 3. Since the engagement plate 5c is rotatably supported by the shaft portion 5b, even if the lifting tool 1 is tilted when the B beam 3 is lifted, the engagement plate 5c is not attached to the upper surface 3c of the B beam 3. There is no corresponding disengagement between the upper surface 3c of the B beam 3 and the engagement plate 5c.

Further, by pulling the operation portion 2s on the string from the ground side and moving the suspending tool 1 with a crane or the like, the suspending tool can be removed only by operating from the ground side. Therefore, the safety and workability are improved compared to the conventional construction method in which the work is carried on the roof of the building.

The suspending tool 1 of the present invention is not limited to these examples, and the specific constitutional requirements such as the shape, size, and material of each member can be appropriately changed in practice. Further, in these embodiments, the case where the B beam 3 is hoisted as an object to be hoisted has been described as an example, but it can also be used when hoisting a building member other than the B beam 3 such as a roof beam. Of course.

[0034]

[Effect of the device]

 As described above, according to the hoisting tool of the present invention, the B-beam can be inserted into the support part and held from below, and the movement of the B-beam can be restricted by the restricting part. Even if the sway occurs due to, for example, the B beam can be securely held and hung. In addition, since it is regulated by the regulation portion, the suspending tool does not slip along the slope of the bottom surface of the B-beam when it is lifted up, and the suspending tool does not fall on the center side. Further, according to the lifting device of the present invention, after the object to be lifted is fixed to the object to be lifted and the object to be lifted is set at a predetermined position, the operation of the operation part on the cord from the ground releases the restriction part, The lifting device can be easily removed from the object to be lifted. Therefore, it is not necessary to carry out the work by mounting it on the roof of the building, and the workability can be improved.
