Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a silo carrier vehicle, and is used for installing or removing a silo storing a storage material such as cement at a construction site or construction.

(Prior Art) Conventionally, as a silo carrier of this type, JP-A-60-60045 has been used.
As can be seen in the publication, the tilting frame for mounting and supporting the silo is tiltably supported on the rear part of the vehicle body frame, and the front part of the tilting frame is provided with an L-shaped frame which can be expanded and contracted in the front-back direction. There is provided a silo carrier configured to load and unload silos by tilting a tilting frame by a tilting cylinder and extending and contracting an L-shaped frame back and forth.

(Problems to be solved by the invention) However, in the above-mentioned conventional apparatus, the tilting frame is vertically erected, and then the L-shaped frame is retracted to lower the silo in the erected state downward and wholesale it on the ground. Therefore, the wholesale position of the silo is naturally determined by the parking position of the silo carrier. Therefore, if the parking position of the silo carrier shifts or if the silo is found immediately before unloading the silo to the ground, the silo carrier must be moved to change the silo unloading position. Not only was it troublesome, but the driver's burden was heavy due to the nervousness of the parking position for the silo carrier.

In addition, an air suction pipe for introducing air into the inside of the silo at the time of discharging the stored matter is provided at an appropriate position on the peripheral side surface of the silo, and when the silo is transported to the silo transport vehicle, the silo transport is performed. Due to the height and width restrictions of the vehicle, the air suction tube is placed near the side of the tilting frame that does not interfere. Since the silo is wholesaled from the silo carrier as it is as described above, the position of the air suction pipe is automatically determined, and depending on the installation location, the air suction pipe may interfere with peripheral equipment. There was a problem saying that.

(Means for Solving the Problem) A silo carrier of the present invention is a silo carrier that transports silos placed freely for loading and unloading, in which a tilting frame for mounting the silo on a vehicle body frame is vertical from a horizontal position. A tiltable frame is provided so as to be tiltable, a telescopic first telescopic arm is provided at a front end of the tilt frame in the front-rear direction of the vehicle body, and a telescopic second telescopic arm is provided at a front end of the first telescopic arm. The arm is arranged vertically and is swingably provided in the width direction of the vehicle body. The upper end of the second telescopic arm is engaged with and disengaged from the engaging portion of the silo front end mounted on the tilting frame. A free hook member is rotatably supported.

(Operation) When the silo is unloaded from the silo carrier, when the silo is in a suspended state that is not yet on the ground, the second telescopic arm is extended to move the standing silo back and forth, and the second telescopic Swing the arm across the width of the car body to adjust the silo loading position. Further, since the hook member for suspending and supporting the silo is rotatably supported, the silo is rotated to change its direction, and the air suction pipe provided on the silo is arranged at an appropriate position.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 and 3 show a silo carrier according to the present invention.

A tilting frame 10 is pivotally supported 11 on the body frame 1 so as to be tiltable around its rear end. The tilting frame 10 is for mounting the silo 2, and by a telescopic movement of a pair of left and right tilting cylinders 12, 12 connected between the tilting frame 10 and the body frame 1, the tilting frame 10 is moved from a horizontal position around the pivot 11 part. It is configured to be tiltable between vertical positions.

The silo 2 is formed in a cylindrical shape, and stores, for example, cement or the like inside and is installed at a construction site or the like. The silo 2 is usually installed in an upright state, the lower end of the silo 2 serves as an outlet (not shown), and an air suction pipe 2a for introducing air into the silo is provided at an appropriate position on the peripheral side surface. . Further, the silo 2 is mounted such that the front portion thereof is mounted as close as possible to the front end portion of the tilting frame 10 when mounted on the silo carrier vehicle.

At the center of the front end of the tilting frame 10, a telescopic first telescopic arm 20 is arranged in the front-rear direction of the vehicle body. The first telescopic arm 20 includes an outer cylinder 21 fixed to the tilting frame 10.
And an inner cylinder 22 slidably fitted in the outer cylinder 21, and a telescopic cylinder 23 provided in the inner cylinder 22 for expanding and contracting the inner cylinder 22.
It consists of and.

A telescopic second telescopic arm 30 is vertically arranged at the tip of the inner cylinder 22 of the first telescopic arm 20, and is swingably provided in the width direction of the vehicle body. Second telescopic arm
The lower cylinder 30 includes an outer cylinder 31 whose lower end is swingably supported by the front end of the inner cylinder 22, and an inner cylinder 32 slidably fitted in the outer cylinder 31.
And a telescopic cylinder 33 that is provided inside the inner tube 32 and that telescopically moves the inner tube 32. A swing cylinder 35 is connected between the tip of the inner cylinder 22 of the first expandable arm 20 and the base end of the outer cylinder 31 of the second expandable arm 30. The second telescopic arm 30 is swung in the width direction of the vehicle body by the telescopic movement.

A rotary joint is attached to the tip of the inner cylinder 32 of the second telescopic arm 30.
The hook member 40 is pivotally supported via 41. The rotary joint 41 rotatably supports the hook member 40 around its axis.

The hook member 40 is configured to be engageable with and disengageable from the locking portion 3 provided on the front surface of the silo 2 on the tilting frame 10.

In the figure, reference numeral 50 is an outrigger provided on both sides of the rear portion of the vehicle body frame 1, and reference numerals 60 ... are hooks for winding and fixing the silo 2 on which the tilting frame 10 is mounted with a wire or the like.

Next, the operation of the silo carrier configured as described above will be described.

First, as shown in FIG. 1, when the silo 2 mounted on the tilting frame 10 is unloaded from the silo carrier, the outrigger 50 is used.
After supporting the rear part of the silo carrier by extending the tilting cylinders 12 and 12 with the engaging part 3 of the silo 2 and the hook member 40 engaged, the tilting frame 10 is rotated. Is tilted from the horizontal position to the vertical position around the 11th support. When the tilting frame 10 is tilted, the telescopic cylinder 33 extends the inner cylinder 32 of the second telescopic arm 30 to lift the front part of the silo 2 above the front end of the tilting frame 10 and then the telescopic cylinder 23 moves the 1. The inner cylinder 22 of the telescopic arm 20 is extended to pull up the silo 2 to the front end side of the tilting frame 10. Thus tilting frame 10
By tilting the to the vertical position, the silo 2 mounted on the tilting frame 10 stands up.

After that, when the inner cylinder 22 of the first telescopic arm 20 is retracted into the outer cylinder 21, the silo 2 moves downward, and the lower end of the silo 2 is grounded and grounded (see FIG. 4). As a result, the silo 2 storing cement or the like can be installed at a construction site, a factory, or the like.

Here, when installing the silo 2 in this way,
When the silo 2 is in the suspended state where it has not been placed on the ground yet, the inner cylinder 32 of the second telescopic arm 30 is extended from the outer cylinder 31 by the telescopic cylinder 33 to move the silo 2 in the standing state back and forth, and The retractable arm 30 can be swung by the swing cylinder 35 in the width direction of the vehicle body to adjust the loading position of the silo 2. Further, since the hook member 40 is rotatably supported by the second telescopic arm 30, it is necessary for the operator to appropriately rotate the silo 2 to change its direction so that the air suction pipe 2a of the silo 2 is arranged at an appropriate position. You can

In this way, the unloading position of the silo 2 can be adjusted before the unloading of the silo 2, so that the silo 2 can be easily installed at a predetermined location even if the parking position of the silo carrier is slightly shifted. . In addition, since the direction of the silo 2 can be changed before unloading the silo 2, the air suction pipe 2a provided in the silo 2 can be arranged at a safe position where it does not interfere with peripheral equipment. Here, in the silo 2, when the tilting frame 10 is mounted, the air suction pipe 2a thereof is arranged close to the side portion of the tilting frame 10 in order to regulate the height and width of the silo carrier.

When the silo 2 installed at a construction site or a factory is mounted on a silo carrier, the operation is performed in the reverse order of the above operation.

In this example, the hook member 40 rotatably supported by the second telescopic arm 30 is used to appropriately change the orientation of the silo 2 by the operator. It may be configured to be rotationally driven by a driving device such as.

(Effects of the Invention) As described above, according to the present invention, when the parking position of the silo carrier is slightly displaced or there is some unevenness in the unstocking position, it is possible to use the means before the silo is ungrounded. (2) The retracting position of the silo can be adjusted by expanding and contracting and swinging the expanding and contracting arm, and the silo can be easily installed at a predetermined position and avoiding unevenness. Further, since the hook member is rotatably supported by the second telescopic arm, the orientation of the silo can be changed at a stage before the silo is unloaded, and the air suction pipe provided in the silo interferes with peripheral equipment. It can be placed in a safe position where it does not happen.
