BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation apparatus applied to a work vehicle following a shield excavator.

[0002]

When BACKGROUND ART illustrating a conventional mounting apparatus to FIG 7, a is in the truck, in the same truck a, there is a pinion a ₁ attached to the output shaft of the geared motor and the motor. telescopic mechanism b is mounted on the same carriage a (hydraulic cylinder or electric cylinder), e is the assembly gripping frame attached to the distal end of the telescopic mechanism b, d is revolving frame, d ₁ is the revolving frame d The gear provided on the outer periphery of the pinion a ₁
There has been engaged in the same gear d _1. f ₁ is the assembly of segments such as, f ₂ is the existing assembly.

[0003] In the mounting apparatus, to be assembly f ₁ is gripped by the assembly gripping frame e, along the carriage a to the rotating frame d is run up installation position, then actuates the stretching mechanism b in the direction of elongation , carries the target assembly f ₁ to installation position, and then operates the same extension mechanism b at very low speed, carrying the target assembly f
₁ Adjust the position with respect to existing assembly f _2, then fixed by a fastener these target assemblies f ₁ and the existing assembly f _2. Thereafter, the same operation is repeated to assemble the article to be assembled f1 _one after another.

[0004]

In the conventional installation apparatus shown in FIG. 7, (1) since the entire weight of the gripping mechanisms a, b, and e is driven by the geared motor on the carriage a, large power is required. Become. Further, since the geared motor is mounted on the carriage a, manual operation is difficult, and it is not possible to perform ultra-slow driving manually. (2) When the turning speed is controlled by the inverter motor, the speed ratio of 1/10 is the limit. In this case, too, it is difficult to drive at a very low speed.
Ultra-slow drive by hand cannot be performed. In the case of a servo motor or a stepping motor, there is a problem that the cost is high.

The present invention is proposed in view of the above-mentioned problems, and its object is to reduce the power for turning drive, drive it at a very low speed by hand, and adjust the position during assembly and installation. An object of the present invention is to provide an installation device that can be accurately performed.

[0006]

In order to achieve the above object, an installation apparatus according to the present invention includes a swing frame, a truck traveling along the swing frame, and a telescopic mechanism mounted on the truck. A gripping mechanism comprising an assembly gripping frame attached to the distal end of a telescopic mechanism, a trolley traveling drive device which can be automatically and manually operated attached to the member on the turning frame side, and an attachment to the member on the turning frame side And a balancing weight that moves up and down along the lifting guide member, such that when the gripping mechanism moves to the top of the revolving frame, the balancing weight moves to the bottom of the lifting guide member. The bogie of the gripping mechanism and the balancing weight are connected by a wire.

[0007]

When the gripping mechanism 2 moves to the top of the revolving frame 1 as shown in FIG. 6A, the balancing weight 7a moves to the bottom of the elevating guide member 11, and the gripping mechanism 2 and the balancing weight 7a catch. Fit. Also, when the gripping mechanism 2 moves to the position 2 'in the direction of the arrow a in FIG. 6B, and when it moves to the position 2 "in the direction of the arrow b, the balancing weight 7a moves 7' in the direction of the arrow c. The gripping mechanism 2 and the balancing weight 7
a is balanced. By this balancing action, the motive power of the trolley traveling drive device 4 that causes the trolley 2a of the gripping mechanism 2 to travel along the turning frame 1 is reduced. Therefore, the manual handle 4 is attached to the intermediate input shaft of the speed reducer of the geared motor 4a with brake.
c, the brake of the geared motor with brake 4a is released, and the bogie 2a of the gripping mechanism 2 can be moved by human power.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the installation apparatus of the present invention will be described with reference to one embodiment shown in FIGS. 1 to 6. Reference numeral 1 denotes a turning frame, and 2 denotes a gripping mechanism. The gripping mechanism 2 is composed of a truck 2a running along the turning frame 1, an expansion / contraction mechanism 2b mounted on the carriage 2a, and an assembling object gripping frame 2c mounted on a distal end of the expansion / contraction mechanism 2b. It is configured. This gripping mechanism 2
Operates the telescopic mechanism 2b in the telescopic direction at a predetermined turning position,
The article 3 is positioned, and the article 3 is assembled and installed.

Reference numeral 4 denotes an automatic / manually-operable traveling drive for a truck mounted on a scaffold 12 (see FIG. 4) on the side of the revolving frame 1. The traveling drive for the truck 4 includes a geared motor 4a with a brake, A twin-type winding drum 4b rotationally driven by the geared motor 4a, a wire 5a wound on one of the double-type winding drums 4b, and a wire 5b wound on the other of the double-type winding drum 4b. It consists of.

The wire 5a is connected to the turning frame 1
Traveling carriage 2 through a sheave 6a attached to the inner peripheral part on one side of the vehicle and a number of sheaves attached to the outer peripheral part on one side of the revolving frame 1.
a, the wire 5b is connected to a sheave 6b attached to the remaining inner peripheral portion of one side of the revolving frame 1 and the revolving frame 1
Is attached to the traveling vehicle 2a through a number of sheaves attached to the outer peripheral portion on one side, and when the twin-type winding drum 4b is rotated, one of the wires 5a and 5b is loosened and the other is pulled, and the traveling vehicle 2 a travels along the turning frame 1.

Reference numeral 7 denotes a balancing mechanism. The balancing mechanism 7 has a ratio of the turning radius R of the center of gravity G of the gripping mechanism 2 to the lifting / lowering radius r of the center of gravity of the balancing weight 7a. i and the number n of the suspension wires of the balancing weight 7a, that is,

[0012]

(Equation 1)

It is configured so that An elevating guide member 11 is attached to a member on the revolving frame 1 side, and the balancing weight 7a moves up and down along the elevating guide member 11. 9 is the balancing weight 7a
The wire 9 is connected to the carriage 2a via a sheave 10 for increasing the number of suspension wires of the balancing weight 7a and a sheave 8 for guiding the wire 9.

When the gripping mechanism 2 moves to the top of the revolving frame 1 as shown in FIG. 6A, the balancing weight 7a moves to the bottom of the elevating guide member 11, so that the gripping mechanism 2 and the balancing weight 7a catch. Fit. Also, when the gripping mechanism 2 moves to the position 2 'in the direction of the arrow a in FIG. 6B, and when it moves to the position 2 "in the direction of the arrow b, the balancing weight 7a moves 7' in the direction of the arrow c. After moving to the position, the gripping mechanism 2 and the balancing weight 7a are balanced.

By this balancing action, the carriage 2 of the gripping mechanism 2
The power of the trolley traveling drive unit 4 that drives the vehicle a along the revolving frame 1 is reduced. Therefore, it becomes possible to insert the manual handle 4c into the intermediate input shaft of the speed reducer of the geared motor 4a with brake, release the brake of the geared motor 4a with brake, and move the bogie 2a of the gripping mechanism 2 by human power.

[0016]

As described above, the installation device of the present invention balances the gripping mechanism and the balancing weight as described above, so that it is possible to reduce the power of the geared motor with a brake that drives the carriage of the gripping mechanism along the turning frame. . In addition, as described above, the turning drive power of the geared motor with brake can be reduced, so insert the manual handle into the intermediate input shaft of the geared motor with brake, release the brake of the geared motor with brake, and The cart of the gripping mechanism can be moved, and the positioning at the time of assembly and installation can be performed accurately.
