Description

[Detailed Description of the Invention] The present invention is characterized in that a cylindrical member is fixed to the machine frame in an upwardly open state, and a support for a loading platform side plate inserted into the cylindrical member is inserted and removed by penetrating both. The present invention relates to a structure for mounting a support for a side plate of a carrier vehicle, which is connected via a freely pivotable pivot shaft and fixed by a horizontal bolt interposed between the two.

The support for the side plate of the loading platform is installed as described above so that it is possible to transport iron plates that are larger than the loading surface, or to transport long objects such as pipes and steel frames, and to load and unload them on the slope of the loading platform. Conventionally, as shown in FIGS. 5 and 6, a support column 11 connected to a cylindrical member 10 via a pivot shaft 17 is fixed. The support column 1 in a direction substantially perpendicular to the pivot shaft 17
Two horizontal poles I-20 that press on both sides of 1,
20, and those poles) Since one horizontal bolt 20 that exerts a pressing action was provided on one side adjacent to the side on which the pole 20 acts, the support 11 around the poles 1-20 and 20 of the same layer P was There are drawbacks such as the prop 11 easily falling down, the standing posture of the column 11 becoming unstable, and a gap being created between the column and the side plate 9, or the attachment of the side plate 9 becoming difficult.

More specifically, when attaching the support column 11, the angle of the support column 11 around the pivot shaft 17 is adjusted and the angle of the support column 11 is reliably maintained.
Regardless of the looseness of the parts, the support column 1 is centered around the bolt clamping part.
It is necessary to fix the pivot shaft 1 so that it does not fall down unexpectedly in the direction of the pivot drive shaft, but according to the above conventional structure, the pivot shaft 1
There was a risk of an unexpected collapse due to the looseness of the 7 parts.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to strengthen the support column by improving the arrangement of the horizontal bolts while taking advantage of the simple structure of the test using three horizontal bolts. The point is to allow it to be mounted on.

A characteristic configuration of the support support mounting structure for the side plate of a transport vehicle according to the present invention is such that the bolts are located at intervals in the longitudinal direction of the support support, and are arranged on one side of the support support in a direction substantially perpendicular to the pivot axis. It consists of two bolts that press against the surface and one bolt that presses on the other side toward the middle of the two poles, and the effects are as follows.

That is, by applying pressure to each of the two opposing sides of the column and holding the column between two bolts and one bolt along the direction perpendicular to the pivot axis,
While adjusting the angle of the column around the pivot axis by adjusting the bolts, it is possible to reliably maintain that state.Moreover, when viewed in the direction of the bolt axis, the two bolts that press against the side of the column By positioning the other side of the column on both sides of the single bolt that acts as a pressure, it is possible to prevent the column from falling in the direction of the axis of the pivot shaft around the bolt clamping part due to play in the pivot shaft part. The pressing support force of two bolts can be reliably blocked while acting as a moment centered on one bolt.

In addition, since the two bolts are positioned at a distance in the longitudinal direction of the support, the length of the support itself can be effectively utilized while the two bolts are positioned at a large distance. It is also possible to fully utilize the moment action described above.

In other words, as shown in Figure 4, two poles) 18.1
If the poles H8, 18 are arranged in the axial direction of the pivot shaft 17, there is a disadvantage that the two poles H8, 18 cannot be located within the limited ridge of the support 11 with a large distance between them.

Therefore, with a simple structure using three bolts, the angle of the pivot shaft can be adjusted around the axis while reliably maintaining that state. It is now possible to reliably prevent the column from falling in the axial direction and to securely fix the column in a predetermined position.

First, an embodiment of the present invention will be described based on the drawings.

A transport vehicle is constructed by attaching a loading platform 4 to a vehicle body 2 equipped with a wheel-type traveling device 1 so as to be able to freely drive and swing around a horizontal horizontal axis 3 at one end thereof, and a control section 5 and a driving section 6 arranged side by side at the other end of the vehicle body. It consists of:

The loading platform 4 is constructed by attaching horizontal side plates 9, 9 to the bottom plate machine frame 8 for seedlings to which the front side plate 7 is attached, so as to be able to swing freely around the horizontal longitudinal axis on both sides, and the bottom plate machine frame 8. The column mounting cylindrical member 10 is opened upward at the rear end corner.
．． 10, and a column 11.11 is removably inserted into the cylindrical member 10.10, and a side plate 12 swinging around a horizontal horizontal axis on the upper end side is attached to the column 11.10.
11, and a locking mechanism that automatically releases the lock as the loading platform inclines is provided across the lower end of the tilting side plate 12 and the lower surface of the bottom plate machine frame 8, and also fixes the standing posture of the horizontal side plate 9. A mechanism 14.14 is provided to transport and release soil, etc., or to stir the side plate 12 and support column 11.
11 and both side plates 9. -9 is folded outward from the machine body, so that articles that protrude beyond the bottom plate machine frame 8 can be transported and discharged.

To erect and fix the support column 11 to the cylindrical member 10,
As shown in FIGS. 2 and 3, a pipe 15 is inserted through the upper side of the inner fitting portion of the support 11 into the cylindrical member 10, with its axis parallel to the axis. A hole 16.16 which is concentric with the pipe 15 and has approximately the same diameter is bored in the cylindrical member 10, and the pivot shaft 17 is inserted and removably inserted through the hole 16, 16 and the pipe 15. 1
0 and the support column 11, and three horizontal poles H8, 19 which act to press against the side surface of the support column while sandwiching the support column 11 below the pivot shaft 17, are attached to the pivot shaft 1.
7 and threadedly attached to the cylindrical member 10, two of these bolts 18 are placed at different positions in the longitudinal direction of the column and pressed against one side of the column 11, and the remaining one bolt 19 is provided by applying pressure to the other side of the pillar 11 in a state facing the middle of the poles 18, 18, thereby making the pole
18. The structure is such that the support 11 is fixed to the cylindrical member 10 in a state where the gap between the support 11 with respect to the side plate 9 and the standing posture of the support 11 can be adjusted by adjusting the tightening of the support 18.

Note that the pivot shaft 17 that connects the support column 11 to the cylindrical member 10 is
The axis may be made parallel to the swing axis of the side plate 9.
