好適なオートバランスシステムの吊込ビームに関
する。[Detailed explanation of the invention] "Industrial application field" This invention is used when a tower crane installed on an upper floor carries and attaches materials to a position shifted inward from the crane hook position on a lower floor. The present invention relates to a suspension beam of an autobalance system suitable for use in a vehicle.

ものとなる。``Conventional technology'' When carrying out floor and finishing work after preliminary erection of steel frames, when attempting to carry and install materials to the lower floor using a tower crane installed on the upper floor, it is difficult to The installation position may be shifted inward from the crane hook position. In particular, if there is a scissor-tack scaffolding or external wall curing rope protruding from the top, the gap will be even larger.

This requires leaning out from inside the building, using a pulling device to pull it in, or setting up a lifting stage, but this is extremely dangerous, and setting up a stage with the assumption that it will be removed is redundant. I don't like it because it forces me to go through some process. Therefore, a balance beam that can control the movement of balance weights to a balanced position was developed in U.S. Pat.
It has been proposed in Utility Model Application Publication No. 59-176874.

The reason is that the motor for driving the pinion must be placed on the balance weight side of the moving body, which makes it difficult to secure enough weight for the space it occupies, and the motor cord is dragged by the balance weight of the moving body, resulting in breakage accidents. There are various practical difficulties, such as the tendency to cause problems.

解消した点にある。``Means for solving problems'' and ``effects'' This proposal was made in view of the circumstances described above, and its gist is that the structure of the hanging beam should be placed within a rectangular surrounding steel frame with legs. A balance weight with a running roller is assembled via a guide rail in such a manner that its bottom side fits within the leg, and a ball screw driven by an electric motor is installed in the longitudinal direction of the steel frame, and a nut block screwed onto the ball screw is installed. If the electric motor is connected to a balance weight and the electric motor is controlled by a tilt sensor mounted on the steel frame, even if the positions of the crane hook and the suspended load on the suspension beam are misaligned, the balance weight will not move within the steel frame. By controlling the movement of the suspension beam, it is possible to lift the suspension beam at a position horizontally apart from the crane hook position while keeping it in a horizontal position. This provides a balance function to the rectangular steel frame, which can be placed stably, and eliminates the need for a motor on the movable body, thereby solving the inconveniences of the conventional ones mentioned above.

2 is a running roller 2 assembled in the steel frame 1.
A is an attached balance weight, and in the illustrated example, it is assembled using a steel frame groove of C-shaped steel as a guide rail. However, balance weight 2
is movable in the longitudinal direction within the steel frame 1, and its base is located above the tip of the leg 1a, so when the surrounding steel frame 1 is placed on the ground during maintenance, it will not hit the ground. Reference numeral 3 denotes a ball screw installed in the longitudinal direction of the steel frame 1, which is supported at both ends by pillow blocks 4 as shown in detail in FIG. 2, and is driven forward and backward by an electric motor 5 via a transmission mechanism 6. The electric motor 5 is connected to a battery 7 (first battery 7) mounted on the steel frame 1.
(Figure). Numeral 8 is a nut block screwed onto the ball screw 3, and the pin 10 attached to the bottom of the nut block is connected to the bracket 9 attached to the upper surface of the balance weight 2, as shown in detail in FIGS. 3a and 3b. It is combined with weight 2.

Note that the range of movement is regulated by travel limits L and L'. Reference numeral 11 denotes a control panel for the electric motor 5, which receives instructions from a tilt sensor 12 mounted on the steel frame 1 and radio control. 1 in the diagram
3 is the antenna for the above-mentioned radio control. The tilt sensor 12 is shown in detail in FIGS. 4a and 4b. Although not shown in the figure, a through hole is bored at the lower end of the pendulum plate 12a, and by passing light through this hole, the neutral sensor 12b and tilt sensor 12c detect the degree of tilt, and this detection signal is used to detect the degree of tilt. Based on the control panel 1
2 controls an electric motor 5. In addition, 12d in the figure
is an attached limit switch for protecting the motor in order to prevent the electric motor 5 from being forced to drive in an excessively inclined position.

別な際に用いられるものである。 Bring the hanging beam to the hanging load 18 and hang the sling wire 19. (Figure a) When the suspension beam is hoisted up, the balance is lost and the balance weight 2 moves backward. At this time, the winding operation is performed gradually by one notch. (Figure b) The suspension beam cuts off the ground in a horizontal state and moves to a predetermined location. (Fig. c) Once the suspended load 18 is placed in the designated location, it is slowly hoisted up with one notch. (Figure d) When the sling wire 19 becomes loose, the balance is lost and the balance weight 2 moves forward. (Figure e) After the balance weight 2 moves forward and remains horizontal, remove the sling wire 19. (Figure f) Note that radio control is used in special cases when it is desired to position the balance weight 2 in a position that is impossible with autobalance.
