Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction vehicle, and particularly to a construction vehicle that is particularly effective for tunnel construction, for example.

Generally, when carrying out tunnel construction, after the excavation work,
7. Damages caused by nuclear drilling operations.
; A curved object is constructed. This is what is called shoring. In this way, during tunnel construction, at least two beams on the sides of the two buildings are damaged during excavation and erection of support. Conventionally, each of these operations required a dedicated unit, ie, an excavation work table such as a gludozer, and a shoring work vehicle. However, having to use a dedicated vehicle for each job in this way is inconvenient, both from the perspective of transporting the work vehicle to the site and from the standpoint of maintaining equipment at the site.

The present invention has been developed in view of the above.

In other words, the purpose of Hon@Moe is to provide a construction vehicle that can perform functions appropriate to the work required of the work vehicle.

Hereinafter, an example of misfire 1 and light will be explained in accordance with the following four boxes.

In the drawings, reference numeral 1 denotes a dozer whitebel body, on the upper part of which a pair of pawl arm μ-arms 6.6 connected to a lift cylinder 2 are arranged in parallel toward the front. Further, the lift cylinder 2 is incorporated into a hydraulic circuit (not shown), and can synchronously lift both parallel arms 6.3 by its extension side operation. Various workpieces are attached to the IJ ends of both parallel arms 6.6 in accordance with the required work. In this example, when the entire excavation temple is to be completely discharged by the 4ffll excavation site, a shovel packet with no dents is attached, and when the shoring is being erected, attachment A as shown in the figure is attached. This attachment A) will be explained below.

W is a support frame framed in a grid pattern, and then 1...
A pair of attachments located at the same location on one edge are attached to the insert pins 5, 5 to both the puffer μ arms 5.6 at the bracket 4゜4.
It is installed horizontally and removably through the Further, a main deck 6 for work is mounted on this support frame W, and the main deck 6 is supported by a center cylinder 7 horizontally supported at the center of the support frame W on the lower surface side of the main deck 6. It can slide forward and backward. Next, mW for supporting the sliding movement of the main deck 6 will be explained.

On both the left and right edges of the bottom surface of the main deck 6, to the rear of the main deck 6! 9. Outer rail extended for a fixed length 8.8
is deeply felt. And each 7 utare/I'a
At the rear of 8, a pair of side rollers 9, 9 move forward and backward.
They are distributed at regular intervals.

Each side roller? , 9 are removably fitted into both channel-shaped spheres /L'IO, 10 disposed on both left and right sides of the support frame W. On the other hand, on the front edge of the support frame W, four front rollers 12 to 12 are arranged at approximately equal intervals as shown in the figure, each having a rotary function. 12 and fy,
I#Jt can support the sliding movement of the main deck 6.

The center cylinder 7Fi is connected to the aforementioned hydraulic circuit, and can be expanded and contracted at a slow speed by an operating device (not shown) that performs overall control of the hydraulic circuit. Also, 14
is a safety net stretched over the support frame W.

15.15 is a pair of sub decks that are supported by 16 hinges on both sides of the main deck 6 so that they can be folded and folded. It is connected to each rod end of a folding cylinder 18.18 which is mounted through. This yen! The JTD-m cylinder 18.18 is connected to the above-mentioned hydraulic circuit, and when traveling, the sub-deck 15.
15 are placed in the extended position to hold them in an upright position, and during operation they can be retracted and folded into a horizontal position either synchronously with each other or individually.

Next, the erector 24 for supporting the shoring 25 during erection work will be explained.

19.19i1: The guide tubes of the pool 20 are supported horizontally at the rear end of the upper surface of the support frame W via appropriate plackets.

The poom 20 is attached to both guides M19.19 in the front and rear directions. ! (It is incorporated into the IJ IIJ function, and is supported in a horizontal state by the mouth pairs 21 and 21 built in at the front and rear of the guide port 19, respectively, and its sliding (smoothness of movement is maintained).

In addition, there is a pool 20 on the bottom side of both guides 19 and 19.
A feeding device 22 is installed 7a. Although not shown in detail, this feeding device 22 is composed of a rack and a pinion shaft A: ■ combination whose driving source is a hydraulic motor connected to the aforementioned hydraulic circuit.

Also, an erector 24 is connected to the front end of both booms 20, 20 via an erector hanger 26, which is a parallelogram link.
is installed, and the erector 24 can be tilted by a tilt cylinder 26 connected to the aforementioned hydraulic circuit. Furthermore, each erector 24.24 has a shoring 25
In particular, as shown in Figure E, for the arch-shaped support 25, the upper end is chamfered 27 with a downward slope from the inside to the outside. (Figure 6 P-J'1K ()).

In addition, 28 is a 78 removal ij at the rear of the dozer excavator body 1.
29 is a rigger for preventing the main body 1 from shifting.

Continuing on, the f[ use and young fruit button of this example related to the above configuration will be specifically explained.

After the tunnel excavation work, the shoring 25 is erected - First, the packet of the dozer shell is removed, and the installation of attachment A in this example is made.

The mounting plate can be easily removed by pulling out the insert pin 5, and at this time, the hydraulic system 1 of each cylinder of the attachment A and the hydraulic circuit of the dozer shovel body 1 are removed. Connection work will also be carried out at the same time.

When the replacement work of the attachment member A is thus completed, the dozer shovel main body 1 is inserted into the tunnel.

However, while the vehicle is being carried in, both sub decks 15, 15 are held folded in an upright state.

Then, at the work site, the dozer excavator
Go 29.29%J is set to perform preliminary work such as preventing slippage. After this, one end of the arched shoring 25 is
The rack is passed between the lij erectors 24 and 2.4, and is clamped by each erector 24.24. Then, while the operator is seated on the main deck 6, the lift cylinder 2 is extended to lift the entire attachment. At this time, the main deck 6 is always held in a horizontal state by the parallel arm 6 and is translated upward. this attachment)
Lifting A! According to II rff, the shoring 25 is lifted to an appropriate height by the erector 24 with the grounding end set to 0.

Under this, the cWM work of the shoring 25 is performed. That is, by extending the center cylinder 7, the main deck 6
is slowly advanced along the support frame W to guide the worker to a desired work position. Then, the shield tightening work is performed while the tilt cylinder 26 is expanded and contracted as necessary to adjust the lifting height of the shoring 25 to a predetermined height. Furthermore, in this example, by contracting the folding cylinder 18, the sub-deck 15 can be turned to a horizontal position, thereby making it possible to secure a wider platform for work. Furthermore, in this example, since the erector 24 can be reversed in the front-back direction, the dozer whitebell main body 1 can be installed without moving the dozer white bell body 1 within the extension range of the pool 20 when the shoring supports are erected sequentially in the tunnel excavation direction. The above operations can be performed.

In this way, according to this example, the packet and 111m of waste are attached to the dozer whitebell. This allows the Sidozer excavator to perform both excavation and shoring functions.
You can choose between these two functions depending on your work.

Therefore, unlike the conventional method, there is an advantage that a dedicated vehicle is not required for each task.

Although this example is an attachment for erecting a shoring structure, instead of the erector 24 of this example, it may be possible to install a rock-drilling rig, for example, in place of the erector 24.
