Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of transport machinery, especially relates to freight self-unloading carrying equipment technology. BACKGROUND

[0002] The self-unloading vehicle is a vehicle which can unload goods by itself through hydraulic or mechanical lifting. It is generally composed of a vehicle chassis, a hydraulic lifting mechanism, a cargo compartment and a power take-off device. It often works together with excavators, loaders, belt conveyors and other engineering machinery to form a loading, transporting and unloading production line for loading and transporting earth, sand and bulk materials.

[0003] The cargo compartment of the self-unloading vehicle can be tilted backward or sideways. The piston rod is controlled by a control system to move the cargo compartment. The backward tilting is more common. The piston rod is pushed to make the cargo compartment tilt. Therefore, the structural strength of the cargo compartment is particularly important for the long-term use of the self-unloading vehicle. At present, the cargo compartment of the self-unloading vehicle is mostly formed by welding a pipe frame and a skin. During the manufacturing process, a large amount of welding is required, and there are many welding points. The material is prone to thermal deformation and tension. In the later use process, the welding points are prone to cracking, and the failure rate is high. SUMMARY

[0004] The utility model aims at providing a self-unloading vehicle compartment to solve the technical problem of thermal deformation of the material after the vehicle compartment is welded.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows:

[0007] Further, a plurality of reinforcing ribs are arranged on the bent panel.

[0008] Further, the reinforcing ribs are protrusions on the bent panel.

[0009] Further, the reinforcing ribs are parallel to each other and are manufactured by one-time forming by a machine.

[0010] Further, the reinforcing ribs are protruding circular arc grooves on the bent panel.

[0011] Further, the cross section of the upper cross beam is rectangular, the cross section of the lower cross beam is trapezoidal, and the height of the longitudinal beam is consistent with that of the upper and lower cross beams.

[0012] Further, the second longitudinal beams are arranged between the longitudinal beams, and the height of the second longitudinal beams is lower than that of the upper cross beam and the lower cross beam.

[0013] Further, one or more second longitudinal beams are arranged between the longitudinal beams.

[0014] Further, the reinforcing blocks are arranged at the connection between the reinforcing ribs and the longitudinal beams and the second longitudinal beams, and the shape of the reinforcing blocks is the same as that of the reinforcing ribs.

[0015] Further, the anti-collision rods are provided with a plurality of mounting plates, and the mounting plates are provided with holes.

[0016] The technical scheme of the utility model has the following advantages:

[0017] 1. The arc-shaped reinforcing ribs on the bent face plate are convenient to process, reduce the welding amount and the number of welding points, can release the tension caused by thermal deformation during welding, and the structure of the reinforcing ribs can also increase the strength of the cargo compartment plate.

[0027] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in combination with the drawings.

[0028] Embodiment 1

[0029] As Figures 1-8 shown, the utility model discloses a self-unloading carriage, including automobile chassis 1, hydraulic lifting mechanism 4, goods carriage 2, power takeoff device 3, the goods carriage 2 with automobile chassis 1 one end swing joint, the other end is connected through hydraulic lifting mechanism 4, and the power takeoff device 3 and crash bar 5 are equipped under automobile chassis 1, the goods carriage 2 is composed of front plate 23, side plate 21 and tail door 22.

[0030] In the technical implementation process of the application, the front plate 23 is a structural frame 231, and the gap between the structural frames 231 is closed by the bent panel 6.

[0031] In the technical implementation process of the application, the side plate 21 and the tail door 22 are each composed of a pair of parallel upper cross beams 2111 and lower cross beams 212, and a plurality of longitudinal beams 213 are arranged between the upper cross beams 211 and the lower cross beams 212 to form a rectangular frame. The bent panel 6 is arranged between the longitudinal beams 213, and the bent panel 6 is connected to the upper cross beams 211, the lower cross beams 212 and the longitudinal beams 213 by way of row welding.

[0032] Specifically, the bent panel 6 is a plate structure, and a plurality of reinforcing ribs 61 are machined on the surface of the bent panel 6. The reinforcing ribs 61 protrude from the bent panel 6 and are parallel to each other. The reinforcing ribs 61 can be manufactured by mechanical extrusion, rolling or bending of metal plates in one step. This avoids the traditional processing method of welding reinforcing ribs on the surface of the metal plate. Compared with the traditional method, the present technical solution consumes less steel, has shorter processing time and is more stable in structure.

[0033] Embodiment 2

[0034] As Figure 4 and Figure 5 shown, in this embodiment, the reinforcing ribs 61 protruding from the bent panel 6 can have a circular arc groove, a rectangular groove or a v-shaped groove structure.

[0035] Embodiment 3

[0036] As Figure 7 shown, in this embodiment, the cross section of the upper cross beam 211 is rectangular and the cross section of the lower cross beam 212 is trapezoidal, and the height of the longitudinal beam 213 is consistent with that of the upper cross beam 211 and the lower cross beam 212. The lower cross beam 212 is located at the bottom of the carriage and receives a larger pressure from the goods in the carriage, and the trapezoidal structure can improve the load-bearing capacity.

[0037] Embodiment 4

[0038] As Figure 6 and Figure 8As shown, in this embodiment, one or more second longitudinal beams 214 are provided between the longitudinal beams 213. The height of the second longitudinal beams 214 is lower than that of the upper crossbeam 211 and the lower crossbeam 212, that is, the height of the second longitudinal beams 214 is less than that of the longitudinal beams 213. This structure results in the second longitudinal beams 214 and the longitudinal beams 213 having different hardness and strength in their respective areas, improving the flexibility of the carriage and eliminating stress concentration.

[0039] Example 5

[0040] like Figure 6 and Figure 4 As shown, in this embodiment, a reinforcing block 62 is provided at the connection between the reinforcing rib 61 and the longitudinal beam 213 and the second longitudinal beam 214. The shape of the reinforcing block 62 is the same as that of the reinforcing rib 61. The reinforcing block 62 is connected to the reinforcing rib 61, the bent panel 6, the longitudinal beam 213 and the second longitudinal beam 214 by welding. The reinforcing block 62 prevents the deformation of the reinforcing rib 61 at the connection between it and the longitudinal beam 213 and the second longitudinal beam 214.

[0041] Example 6

[0042] like Figure 1 and Figure 3 As shown, in this embodiment, the anti-collision bar 5 is provided with several mounting plates 51, and the mounting plates 51 are provided with holes. This facilitates the installation of additional reinforcing structures or warning devices.
