Description

[Detailed Description of the Invention] The present invention relates to a work vehicle for attaching wooden boxes as a heat-insulating lining material to one side of a ceiling tube in a ship's hold.

It is necessary to install a heat insulating lining inside the hold of an LNG carrier, but conventionally this has been done using human labor tactics.

However, since the work is upward-oriented, there are problems in that the work can be difficult and work efficiency is low.

The present invention was made with the aim of eliminating the above-mentioned drawbacks of the conventional means, and is capable of running on the lower end of a plurality of sets of first fluid pressure cylinders arranged in a V-shape when viewed from the side. an underframe is pivotally supported on the upper end of the first fluid pressure cylinder such that the pivot joints between the upper ends of both hydraulic cylinders and the underframe are located on the same axis; When the underframe is horizontal, the upper end of the second fluid pressure cylinder whose lower end is pivotally connected to a required position of so that it comes off,
A third fluid pressure cylinder is disposed on the underframe and includes a plurality of rods that are pivotally connected to a predetermined position of the underframe and can move in opposite directions toward the plane of the underframe. , a frame located on the underframe is pivotally connected to the upper end of the link pivotally connected to the rod tip of the third fluid pressure cylinder, and the underframe is moved up and down and tilted by the first fluid pressure cylinder. , the angle of the underframe is adjusted by the second fluid pressure cylinder, the frame is raised by the third fluid pressure cylinder, and the wooden box placed on the frame is crimped to the ceiling. It is characterized by:

Embodiments of the present invention will be described below with reference to the drawings.

A bracket 3 is attached to either the front or rear of the trolley 2 to which the caster wheels 1 can be mounted and run in any direction.
, 4 are fixedly attached to the brackets 3 and 4, and the axis t1 is attached to the brackets 3 and 4.
A shaft 5 extending in the width direction of the cart 2 is pivotally connected.

A hydraulic cylinder 7 is connected to the outside of the shaft 5 via a key 6.
The lower end boss portion is fixed, and the lower end boss portion of the fluid pressure cylinder 8 is pivotally attached to the substantially central portion of the shaft 5 so as to be rotatable relative to the shaft 5.

Further, the hydraulic cylinders 7.7 are connected by a box-shaped cross-section member 9 so as to maintain parallelism between the two.

A shaft 11 is fixed via a bracket 10 to the front or rear end of the truck 2 opposite to the side to which the shaft 5 is pivoted. is pivoted.

The hydraulic cylinders 8 and 12 are inclined obliquely upward when viewed from the side of the truck 2, and are arranged so that the hydraulic cylinders 8 and 12 are close to each other.

On the other hand, a shaft 15 is fixed to a bracket 14 fixed to the lower surface of the underframe 13 and approximately at the center in the longitudinal direction of the underframe, and the ends of the rods of the hydraulic cylinders 8 and 12 are pivotally attached to the shaft 15. has been done.

Further, the rod end of the fluid pressure cylinder 7 is also pivotally attached to a bracket 16 provided on the underframe 13.

A trunnion 19 of a hydraulic cylinder 18 provided parallel to the underframe 13 is pivotally attached to a bracket 17 fixed to the center of the underframe 13, and the center of the trunnion 19 and the center of the shaft 15 are connected. The connecting straight line t2 is perpendicular to the upper surface or lower surface of the underframe 13.

The rod of the fluid pressure cylinder 18 extends on both sides of the front and back, and the horizontal rail 20 provided on the underframe 13 is attached to the front end of the rod.
The guide wheels 21 that can be moved inside are 11+22
It is pivotally connected via.

Further, the front and rear rods of the hydraulic cylinder 18 are configured such that their tips can expand and contract in the direction toward or away from each other.

A link 23 that faces diagonally upward and away from the center of the underframe 13 is pivoted to the shaft 22 to which the guide wheel 21 is pivoted. It is pivotally attached to a frame 25 on which the holder 24 is placed.

Note that 26 in the figure is a pump unit.

During the work, the rods of each hydraulic cylinder are shortened to the maximum length as shown in FIGS. 1 and 3, and the worker manually aligns and places the required number of wooden boxes 24 on the frame 25.

To attach the wooden box 24 to the horizontal part of the ceiling, push the cart 2 to the required position, extend the rods of the hydraulic cylinders 8 and 12 at the same speed, and also extend the rods of the hydraulic cylinders 8 and 12 at the same speed. It is made to extend in synchronization with the 12 rods.

Then, the underframe 13, the frame 25, and the wooden box 24 also rise while maintaining their substantially horizontal state, and the upper surface of the wooden box 24 reaches the horizontal part of the ceiling.

If the top surface of the wooden box 24 is not completely parallel to the horizontal part of the ceiling, the horizontal level is adjusted by expanding and contracting the fluid pressure cylinder 7.

When the positioning of the wooden box 24 is completed, the front and rear rods of the hydraulic cylinder 18 are all extended at the same time and at the same speed.

Then, the link 23 tries to stand up around the shaft 22, and the wooden box 24 is pressed against the horizontal part of the ceiling.

Then, a worker attaches the wooden box 24 to the horizontal part of the ceiling using bolts that are fixed to the horizontal part of the ceiling in advance.

Once the installation is complete, the work is completed by shortening the rods of each hydraulic cylinder and returning them to their original positions.

When installing the wooden box 24 on a slope, attach the wooden box 24 to the frame 2.
5, the trolley 2 is moved to a desired position, and the rod of the hydraulic cylinder 12 is extended.

Then, the fluid pressure cylinder 7.8, the underframe 13, the frame 25
rotates about the axis 5, and the wooden box 24 changes from the horizontal state shown in FIG. 1 to an inclined state.

If the slope of the top surface of the wooden box 24 is not parallel to the slope, the wooden box 24 is positioned by expanding and contracting the hydraulic cylinder 1.

After the wooden box 24 has been positioned, both rods on both sides of the hydraulic cylinder 18 are extended.

Then, the link 23 rotates so as to stand up against the inclined surface of the underframe 13, and the wooden box 24 is pressed against the inclined surface.

Therefore, the wooden box 24 is attached to the inclined part using bolts that are previously attached to the inclined part.

When the installation of the wooden box 24 is completed, the rods of each hydraulic cylinder are shortened and the frame 25 and the underframe 13 are returned to their original positions.

In the above operation, even if some unbalanced moment occurs with respect to the center line t3 in FIG. Therefore, the underframe 13 is not twisted.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.

According to the work vehicle for use inside a ship hold of the present invention, the wooden box serving as the insulating lining material can be easily attached to the ceiling, so work can be carried out safely and efficiently, and work can be done on horizontal and sloped parts of the ceiling. This can be done with a single work vehicle, reducing equipment costs and increasing machine operating rates.
Furthermore, it can also serve as a carrier for wooden boxes and tools, and the frame that presses the wooden box is equipped with a plurality of rods that face in opposite directions and can move forward and backward in the plane of the frame. Since the frame is raised via a link by a fluid pressure cylinder, the frame rises evenly, and the wooden box can be evenly crimped, which provides various excellent effects.
