Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a truck with a lift and dump device capable of discharging the loaded earth and sand to a high position such as a truck bed.

[0002]

[Prior Art]

 There is a vehicle of this kind, which is provided with a lift and a dump device, which is described in Japanese Utility Model Laid-Open No. 59-113234, but these techniques are simply configured to dump the load platform to the lift frame. Therefore, the loading height of the loading platform is almost the same as the lift frame height, and it cannot be discharged to the rear position away from the airframe. If a chute, etc., is attached to discharge to a position away from the machine, the discharge height will be further reduced.

[0003]

[Problems to be solved by the device]

 The present invention is intended to eliminate the above-mentioned drawbacks and to discharge the earth and sand or the like to be mounted on the loading platform at a high position and away from the machine body.

[0004]

[Means for Solving the Problems]

 A lift frame 5 is provided on a chassis frame 2 having a prime mover 1 mounted at the rear part thereof, which can be raised and lowered while maintaining a substantially horizontal state by a cross link mechanism 4 operated by a hydraulic cylinder 3, and the lift frame 5 has a pivot shaft at its front end. 6 is provided with a dump frame 8 rotatable by a hydraulic cylinder 7, and a rear portion is placed on the dump frame 8 and a front bottom surface 9 is inclined upward and away from the dump frame 8. A lift and dump truck-equipped transport vehicle is formed by mounting a mold carrier 10 and further forming a large space 11 between the front portion of the dump frame 8 and the bottom surface 9 of the bucket carrier.

[0005]

[Advantages and effects of the invention] When the earth and sand to be loaded on the loading platform 10 are discharged, the hydraulic cylinder 3 is extended to erect the cross link mechanism 4, so that the lift frame 5 maintains a substantially horizontal state. Be ascended. Subsequently, when the hydraulic cylinder 7 is extended, the dump frame 8 rotates around the pivot 6 at the front end of the lift arm 5, and the loaded object is discharged from the front portion of the bucket type loading platform 10 mounted on the dump frame 8. At the time of this discharge, the bucket type loading platform 10 has a rear portion mounted on a dump frame 8 rotatable around a pivot 6 at the front end of the lift frame 5 and a front bottom surface 9 inclined upwardly from the dump frame 8. Therefore, the front end discharge position of the bucket type cargo bed 10 is higher than that of the conventional one, and a large space 11 is provided between the front part of the dump frame 8 and the bottom surface 9 of the bottom surface 9 of the bucket type cargo bed 10. Since the space is formed, it can be discharged in the space 11 with the side frame of the truck intervening, for example, and it can also be discharged to the vicinity of the central portion of the truck.

【Example】

 Under the undercarriage frame 2, traveling devices 12, 12 consisting of a pair of left and right crawlers are provided to enable the traveling movement of the transport vehicle. A cross frame mechanism 4 maintains a substantially horizontal state on the front side of the chassis frame 2 and a lift frame 5 that can be moved up and down is provided on the front side thereof. An operation unit 15 is provided at the rear of the unit 14. The cross link mechanism 4 is provided so as to intersect with a pair of left and right main links 16 and sub links 17, and the middle thereof is rotatably supported by a pin 18, and the main link 16 has a lower end at the front end of the chassis frame 2. It is pivotally supported by a pin 19 provided at the upper end of the lift frame 5, and a roller 20 is attached to the upper end of the lift frame 5, and a guide rail 21 fixed to the lower surface of the lift frame 5 has a groove-shaped cross section and is rollably engaged.

The sub-link 17 is pivotally supported at its upper end by a pivot 6 provided at the front end of the lift frame 5, and at its lower end, a roller 20 is attached, and at the same time, the sub-link 17 is fixed to the chassis frame 2 in the form of a groove. Is rotatably engaged with the guide rail 21. Both ends of the hydraulic cylinder 3 are pivotally connected to the bracket 22 below the auxiliary link 17 and the upper part of the main link 16, and the expansion and contraction of the hydraulic cylinder 3 connects the main and auxiliary links 16 and 17 to the intermediate intersection. It is configured to be rotatable around the pin 18.

A dump frame 8 is rotatably supported on both ends of a pivot 6 provided at the front end of the lift frame 5 via left and right brackets 23, 23, and a bracket hanging below the lift frame 5 and a lower surface of the dump frame 8 are provided. A hydraulic cylinder 7 is pivotally connected between the two. A horizontal rear bottom surface 9 is placed directly on the dump frame 8, and the front bottom surface 9 is inclined upwardly above the dump frame 8 and is therefore inclined so that the rear side is deep and the front side is shallow. A loading platform 10 is mounted.

A mounting plate 24 has a lower end attached slightly forward of the center of the dump frame 8 and a bucket type loading platform 10 fixedly attached at the upper portion. On the front side of the mounting plate 24, the bottom surface of the bucket carrier 10 is located above the dump frame 8 and no mounting portion is provided. Therefore, the dump frame 8 and the bottom surface 9 of the bucket carrier 10 are not provided. A large space 11 is formed between and. When discharging the soil or the like to be loaded on the bucket type carrier 10, first, the hydraulic cylinder 3 is extended, and the rollers 20 and 20 provided at one end of each of the main and auxiliary links 16 and 17 are connected to the guide rails 21 and 21. While rolling along, the pin 18 at the intermediate intersection is rotated to stand up, and the lift frame 5 is raised while maintaining the horizontal state.

Next, when the hydraulic cylinder 7 is extended, the dump frame 8 is rotated around the pivot 6 at the front end of the lift frame 5 and is discharged from the front end of the bucket type loading platform 10 mounted on the dump frame 8. It At the time of this discharge, the bucket type loading platform 10 has a rear portion mounted on a dump frame 8 rotatable around a pivot 6 at the front end of the lift frame 5 and a front bottom surface 9 inclined upwardly from the dump frame 8. Therefore, the discharge position at the front end of the bucket type cargo bed 10 is higher than that of the conventional one, and discharge to a high place is possible.

Further, since a large space 11 is formed between the front part of the dump frame 8 and the front part of the bottom surface 9 of the bucket type cargo bed 10, even a state in which a side frame of the truck intervenes in this space 11 The transport vehicle can be brought close to the truck and the load on the loading platform 10 can be discharged near the center of the loading platform of the truck.
