Description

  TECHNICAL FIELD The present invention relates to a crane device having a simple structure for lifting materials and the like used at a construction site and transferring the materials to a predetermined position at the time of construction at a construction site.

Crane equipment is indispensable for carrying materials in construction sites of reinforced concrete buildings, such as middle-rise buildings (3-5th floor buildings) and higher-rise buildings. Crane devices can be roughly classified into two types: fixed crane devices that are fixedly installed at the construction site and move the arm part up and down, and mobile types that are fixed to the car and the arm part expands and contracts and can turn and move up and down. There was a crane truck.
Until now, when constructing a tall building such as a building, a fixed crane device was fixed to the inside of the building to be built or the side of the building, the material was lifted by the crane device and transferred to a predetermined position. .

In addition, when a large crane truck is used to carry construction materials, the large crane truck may interfere with traffic around the site, causing noise and other problems. Was.
Further, when a large crane truck cannot enter the vicinity of the site, it is necessary to lift and carry the material over the adjacent house or telephone pole, and the danger of falling of the material has been a problem.

Fixed cranes used in high-rise buildings such as buildings are often complex and large-scale, and their prices are high. To use this type of fixed cranes for construction of middle-rise buildings , A dedicated operator for operating the crane equipment is required, and a dedicated space for installing the fixed crane, and a reinforced concrete fixed rigid crane base using reinforced concrete anchor bolts dedicated to the fixed crane Has not been used until now.
In addition, it is conceivable to use fixed cranes in a smaller size, but simply reducing the size of the fixed cranes may lead to problems such as a reduction in lifting load, or in buildings that are relatively small compared to large buildings. When installing, it is difficult to operate a fixed crane while maintaining a stable state because it is limited by the narrow land and the place where the crane is installed because the site is narrow, and not only increases the danger at the time of work However, many problems remain simply because of the miniaturization.

  The present invention has been made in view of the above-described problems, and has been designed to simplify the structure of a fixed crane as much as possible so that many materials can be easily, safely and efficiently carried in, and to provide a truss type. The task is to attach a movable support brace to the boom, increase the strength of the truss boom, carry in materials in a stable installation state, and expand the work area, improve work efficiency, and reduce construction costs. And

In order to solve this problem, an invention according to claim 1 is a crane device used in a construction site of a reinforced concrete building, in which a lower lower chord material is suspended above an innermost core column of a telescopic multi-stage column. A truss-type boom formed of car rails is attached with bolts and nuts so that it can be attached and detached and turned to the left and right. Two square pipes are nested at the tip of the suspension car rail, and the upper part of the outer square pipe Attach a suspension car to the suspension rail, and insert a suspension car with a movable support strut with a jacked wheel below the inner square pipe, and attach the suspension car to the upper part of the electric winch, and suspend the suspension car.

An upper support section 16 and a lower support section in which a multi-stage support 6 attached to a fixed base 14 is installed on the ground 10 and an end of the truss boom 2 is mounted on an upper part of an innermost pillar 15 of the multi-stage support 6. 17 is attached to the tip of the truss-type boom 2, and the suspension wheel of the movable support column 13 having the jack-equipped wheel 11 attached to the lower part and the suspension wheel attached to the upper part is attached to the lower chord 4 of the truss-type boom 2. At the construction site, a suspension wheel is attached to the upper part of the electric winch 5 and the suspension wheel attached to the electric winch 5 is inserted into the suspension wheel rail used as the lower chord member 4 of the truss boom 2. FIG. 2 is a front view showing a crane device for lifting and moving a heavy object by using the apparatus.

  FIG. 2 shows an upper suspension wheel 18 composed of a two-wheeled upper and lower wheel with a double wheel on the upper end of a movable support post 13 on the tip of the truss-type boom 2 and the lower chord member 4 (suspension rail). A front view and a left side view show a state where the upper hanging wheel 18 is inserted between the lower hanging wheel 23 and the lower hanging wheel 23.

  The upper chord member 3, the diagonal member 21 and the vertical member 20 of the truss boom 2 are each a steel plate having a thickness of 2.3 mm bent into a U-shape (width 67 mm, height 50 mm) and used as the lower chord member 4. Along with the rail (thickness 3mm, width 67mm, height 90mm, both lower side running parts 21mm, inner upward bent part 15mm) and rigid contacts (joining points of the frame members), it is joined to the truss structure, A square pipe 26 (2.3 mm thick, 80 mm square) and a square pipe 30 (2.3 mm thick, 75 mm square) are inserted into the lower chord 4 (suspension rail) of the truss boom 2 configured as described above. A plurality of pin holes 28 for inserting the pins 27 in the square pipe 26, and a plurality of pin holes 29 for inserting the pins 27 in the square pipe 30. Insert the square pipe 30 into the pipe 26, The pin hole 28 formed in the support 26 and the pin hole 29 formed in the square pipe 30 are aligned so as to be in the same hole position, and then the pin 27 is inserted into the pin hole 28, whereby the movable support column 13 is The height adjustment is enabled, and the male screw bolt 32 of the jacked wheel 11 is inserted into the female screw plate 31 attached to the lower part of the square pipe 30 by turning the rotation lever 19, so that the jacked wheel 11 is inserted into the square pipe 30. Is formed so that it can be moved up and down, and further, on the upper part of the square pipe 26, there are two pairs of double wheels (wheel diameter 78 mm, wheel thickness 9 mm) in front and rear two stages (up and down wheel gap 5 mm). )), And a hanging wheel mounting stand 24 for mounting the lower hanging wheel 23) in the front-rear direction, and inserting a shaft of the hanging wheel into a hole of the hanging wheel mounting stand 24. By fixing a nut 25, movable support strut 13 is formed.

  By inserting the upper suspension wheel 18 of the movable support column 13 configured as described above into the lower chord member 4 (suspension rail) of the truss boom 2, the rail inside the lower chord member 4 (suspension rail) is moved to the upper suspension wheel. 18 can be freely moved back and forth, and by operating the jack operating rod 12 attached to the jacked wheel 11 to change the direction of the wheel 33 of the jacked wheel 11, the movable support column 13 can be moved. It is easy to move the building material forward and backward and to rotate it to the left and right. Also, when lifting the building material with the electric winch 5 at the construction site and moving the material left and right, the truss should be avoided while avoiding the building material placed on the floor. The type boom 2 can be moved back and forth and rotated left and right, and the upper suspension wheel 18 and the lower suspension wheel 23 of the double wheels are divided into two front and rear sets. The movable support column 13 is vertically lifted by inserting a suspension rail of the lower chord member 4 between the upper suspension wheel 18 and the lower suspension wheel 23 by lifting the heavy building material with the electric winch 5. Even when it is shaken, the rattling between the movable support column 13 and the truss boom 2 is minimized, and the suspension wheels (the upper suspension wheel 18 and the lower suspension wheel 23) are composed of two pairs of front and rear parts. The inclination with respect to the direction can be minimized, and the building materials can be moved in a stable state.

  FIG. 3 is a front view and a left side view showing a state where the electric winch 5 is attached to the truss boom 2. In order to fix the suspension wheel 37 to the electric winch 5, a suspension wheel mounting base 40 formed in a substantially convex shape on the upper part of the electric winch 5 is fixed with bolts 38 and nuts 39, and a plurality of suspension wheels are mounted on the upper part of the suspension wheel mounting base 40. The electric winch 5 is fixed by fixing a suspension wheel 37 of a dual wheel (wheel diameter 78 mm, wheel thickness 9 mm) with a nut 41 and inserting the suspension wheel 37 into the lower chord 4 (suspension rail) of the truss boom 2. The building material can be lifted and suspended by rotating the electric winch 5 attached to the boom 2.
