[Prior art]

 Conventionally, a handling work machine that has a track-type or wheel-type lower traveling body that can be replaced with another work tool such as a bucket as a front attachment is usually mounted on the upper revolving structure. Therefore, the dedicated handling work machine was intended for a specific work machine. Moreover, most of these conventional hand-held working machines are intended for loading construction materials, waste materials, etc., and for short-distance transportation, so they could not be lifted and transported to high places.

[0003] Therefore, when transporting construction materials to a high place such as building construction, it is carried out by lifting with a crane or the like, but this is done by simply lifting, and the sticking work is lifted by another worker. It is carried out manually by laying down the above materials and approaching them to the crane position while signaling to the crane operator.In addition, in order to improve the complexity and inefficiency of this crane work, a workbench is attached to the tip of the telescopic boom. An aerial work vehicle has been used, in which construction materials and workers are placed on this workbench and lifted to a high place to perform work such as construction.

However, even in the above-mentioned crane work and aerial work vehicle, work such as building is dangerous because it is necessary to carry and hold heavy construction materials by hand to a predetermined position and at the same time, It was efficient.

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 to 3 show a first embodiment, and FIGS. 4 and 5 show a second embodiment. First, in FIG. 1, a self-propelled vehicle 1 has a hydraulic excavator as a base, and an upper revolving structure 3 rotatably mounted on a track-type lower traveling structure 2 has a driver's cab 4, an engine, hydraulic equipment, etc. A machine cab 5 and a counterweight 6 having a built-in are provided. A boom mounting frame 8 is erected on the revo frame 7 in a backward slanting manner by shaft pins 9 and 10. The base of a telescopic boom 11 having four stages is supported by the shaft pins 12 on the mounting frame 8. In addition, the boom cylinder 13 connected between the frame 8 and the boom 11 can swing up and down.

A work deck 14 is supported by a bifurcated link 15 at the tip of the telescopic boom 11 whose base is supported by the self-propelled vehicle 1. The working deck 14 is attached to one main piece portion 15a of the bifurcated link 15 with a shaft pin 16, and the leveling cylinder 17 is attached to the other piece portion 15b with shaft pins 18 and 19. It is connected between the lower surfaces of the work deck 14. The leveling cylinder 17 is for the work deck 14 to keep horizontal with respect to an angle change due to expansion and contraction of the boom cylinder 13. The work deck 14 supported in this manner can be lifted to a high position such as reaching the fifth and sixth floors of the building as the boom 11 extends.

The work deck 14 has a pole shape surrounded by a protective fence 20 as shown in the figure, and a pallet 21 surrounded by a wire net is placed on the rear half of the work deck 14. A wall stone material 23 to be attached to is stacked. Further, as shown in FIG. 2, a rail 24 is laid in the front-rear direction on the front half of the work deck 14, and a handling machine equipped with a mechanism for canceling a load amount that is already known and commercially available on the rail 24 is used. A so-called balance hand 25 is rotatably mounted, and at the same time as turning, a slide cylinder 26 slides on the rail 24 to move back and forth. In the balance hand 25, a handling device 29 having a suction cup structure is attached to the ends of arms 27 and 28 formed of a two-stage four-bar linkage, and together with the arms 27 and 28, respective cylinders 30, 31, 32. It is designed to work with.

The traveling and turning of the self-propelled vehicle 1 as well as the expansion and contraction and swing of the boom 11 and the operation of the balance hand 25 and the like are performed by a hydraulic system from a hydraulic source of the self-propelled vehicle 1. Further, these operations are performed by the operator of the work deck 14 by remote operation. This remote control can be either wireless or wired.

Next, the operation of the high-altitude handling work machine configured as described above will be described. First, as shown in FIG. 3, the telescopic boom 11 is shrunk to be housed in the upper part of the upper swing body 3, and the stone wall 23 is loaded on the pallet 21 of the working deck 14, and the operator is mounted on the working deck 14. Then, the self-propelled vehicle 1 travels and turns to arrive at the work site. Then, the boom 11 is extended while the boom cylinder 13 is extended along with the extension of the stesco boom 11, and the work deck 14 is set at a high position. When lifted to the position, the operator swivels and swings the balance hand 25 to suck the wall stone material 23 in the rear pallet 21 with the handling device 29 to swivel 180 ° and to move forward on the rail 24 for handling. The wall stone material 23 is attached to the outer wall surface 22 of the building, and this work is repeated while sequentially moving the position. Continued until the wall masonry 23 of Tsu bets 21 is eliminated, and lowered by reducing the boom 1 1 When finished, the joining work is performed increases to again aerial position loading the wall masonry 23. All of these operations are performed by the operator of the work deck 14. The function of moving back and forth on the rail 24 is provided to further enhance the versatility of the work, but even if it is not provided, it can be covered by the movement of the balance hand 25.

An overload prevention device is additionally provided as a safety mechanism for preventing the risk of tipping over during such work at height. This prevention device is electronically controlled, and the detection signals of boom expansion / contraction, boom cylinder pressure, boom angle and turning position are input to the controller to calculate the load factor, which is preset and stored in the controller. When the load condition reaches 90 to 100% of the set safety load factor, the control signal in the range where the safety load factor is not over is output, and the lamp lights up. A buzzer sounds an intermittent alarm, and when 100% is over, it automatically stops.

Next, a second embodiment will be described with reference to FIGS. 4 and 5. Similar to the first embodiment described above, this embodiment has a hydraulic excavator as a base, and in many cases it is composed of the same members such as a telescopic boom and a work deck, and a description of these same constituent members will be made briefly. . The feature of this embodiment is that the hydraulic excavator is divided into a lower traveling body, a machine club and a counterweight of the upper revolving body are self-propelled vehicles, and a handling work machine as a driver's cab and a front attachment is a telescopic boom tip. It is configured to be mounted on a work deck attached to the vehicle. As described in detail with reference to the drawings, in the self-propelled vehicle 101, an upper swing body 103 is mounted on a track-type lower traveling body 102. 103 is equipped with a machine cable 105 and a counterweight 106. A base of a telescopic boom 111 is supported by a shaft pin 112 on a boom mounting frame 108 fixedly mounted on a devo frame 107, and a boom cylinder 113 moves up and down. It is swingable. A work deck 114 is supported by a bifurcated link 115 at the tip of the telescopic boom 111 and is horizontally controlled by a leveling cylinder 117. It has the same configuration as the above-described first embodiment.

A pallet 121 for loading building materials such as shaped steel is placed in the latter half of the work deck 114, and the other half of one self-propelled vehicle 101 formed by dividing a hydraulic excavator as a mother body in the first half. A driver's cab 104, which is a divided portion, and a handling working machine 125, which is a front attachment, are mounted so as to be rotatable. That is, one hydraulic excavator is divided into two, one as a self-propelled vehicle 101 and the other as a handling work machine on the work deck 114 at the end of the telescopic boom 111.

In this embodiment, as in the above-described embodiments, the boom 111, the handling work machine 125, etc. are operated by the hydraulic system from the hydraulic power source of the self-propelled vehicle 101, and the operator on the work deck 114. In addition to performing these operations by remote control, an overload prevention device as a safety mechanism is also attached.

Therefore, when building work at a high place, the construction material 123 such as a steel mold is loaded on the pallet 121, and the operator extends the telescopic boom 111 and the boom cylinder 113 on the work deck 114. The work deck 114 is elevated to a high place by using the handling work machine 125 to handle the material in the pallet 121 and carry it to the building 121 installation position. The holes are aligned and the bolts are fastened in sequence. When the material is lost, the boom 111 is contracted and lowered, the material is loaded, and the work is elevated again to the work position at a high place to perform the building work.
