Description

Technical Field

[0001] The utility model belongs to the technical field of dump truck accessories, in particular to a split-type turnover support seat structure. Background Art

[0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting. It is also called a tipping truck. It consists of a car chassis, a hydraulic lifting mechanism, a cargo compartment, and a power take-off device. The compartment of a dump truck can be divided into two types: backward tipping and side tipping. The movement of the piston rod is controlled by the operating system. Backward tipping is more common. Pushing the piston rod will cause the compartment to tip. A few can tip in both directions.

[0003] The tipping seat of a dump truck is a tipping support device that cooperates with the tipping shaft when the dump truck is lifted. This device is usually a welded or cast one-piece tipping seat that cannot be disassembled. Therefore, if the truck box needs to be disassembled, it is usually necessary to disassemble the tipping shaft to achieve this.

[0004] Under complex engineering road conditions, the working environment of dump trucks is usually harsh and they need to perform dumping operations frequently. Therefore, the performance and durability of the tipping seat are crucial to ensure the normal operation and safety of dump trucks.

[0005] At present, most of the rear flip seat structures of the cargo box on the market of wide-body mining dump trucks are independent flip seats assembled by bolts. The independent left and right flip seat structures need to be welded and manufactured separately, which is costly; the assembly bolt production efficiency is low in actual vehicle production; the left and right flip seats are independent structures, and there is a left and right height error during assembly, which can easily cause uneven force on one side of the cargo box and the frame, directly affecting the service life of the frame.

[0006] The cargo box flipping mechanism is mostly an independent left and right assembly structure with high manufacturing cost; it is assembled through bolts, which consumes labor and has low efficiency; in the actual assembly process, there is also a high probability that the left and right flip seats are not on the same axis due to assembly errors; the assembly type has problems such as loose bolts and insufficient pre-tightening force of manual assembly bolts. Utility Model Content

[0007] In order to solve the problems in the prior art of low assembly efficiency, insufficient pre-tightening force of assembly bolts and misalignment of the flip seat structures on both sides, the utility model provides a split flip support seat structure.

[0008] The utility model is realized by the following technical solutions:

[0009] A split flip support seat structure includes a flip seat outer plate and a flip seat inner plate installed on the bottom surface of a cargo box body, wherein the flip seat outer plate and the flip seat inner plate are welded to the cargo box body; reinforcing ribs connected to the cargo box body are respectively arranged on the side opposite to the flip seat outer plate and the flip seat inner plate.

[0010] The outer vertical plate of the flip seat and the inner vertical plate of the flip seat are separately welded to the bottom surface of the cargo box body, which has high assembly efficiency and avoids the cumbersome installation through bolts and insufficient preload force caused by negligent operation. Since the outer vertical plate of the flip plate and the inner vertical plate of the flip seat are both plate structures, they can be directly welded to the cargo box body after processing and forming, reducing the risk of different axes.

[0011] A further improvement of the utility model is that the outer and inner vertical plates of the flip seat are provided with an escape space that matches the cargo box cross beam on the bottom surface of the cargo box body. The escape space is completely in line with the shape of the cargo box cross beam, and the structures are mutually matched to limit the front and rear positions of the flip support seat and increase the stability of the flip support seat, while reducing the stress on the weld and improving the safety and reliability of flipping.

[0012] A further improvement of the utility model is that the avoidance space is respectively arranged at one end of the outer vertical plate of the flip seat and the inner vertical plate of the flip seat, and the outer vertical plate of the flip seat and the inner vertical plate of the flip seat are respectively in a structure with one corner missing as a whole.

[0013] A further improvement of the utility model is that the avoidance space is respectively arranged at one end of the outer vertical plate of the flip seat and the inner vertical plate of the flip seat, and the outer vertical plate of the flip seat and the inner vertical plate of the flip seat are respectively in a U-shaped structure.

[0014] A further improvement of the utility model is that the length of the outer vertical plate of the flip seat is greater than the length of the inner vertical plate of the flip seat; the avoidance space is provided on one end of the outer vertical plate of the flip seat, and the outer vertical plate of the flip seat is a U-shaped structure; the avoidance space is provided on one end of the inner vertical plate of the flip seat, and the inner vertical plate of the flip seat is a structure with one corner missing as a whole.

[0015] A further improvement of the utility model is that both the outer vertical plate and the inner vertical plate of the flip seat are provided with a vertical flip seat cushion plate, which increases the contact area with the cargo box body and facilitates the installation of the plate on the cargo box body.

[0016] A further improvement of the utility model is that the above-mentioned flip seat cushion plates are respectively arranged on the opposite sides of the flip seat outer vertical plate and the flip seat inner vertical plate.

[0017] A further improvement of the utility model is that the shaft holes of the outer vertical plate and the inner vertical plate of the flip seat are provided with shaft sleeves that match the pin shaft body. The outer vertical plate and the inner vertical plate of the flip seat are both provided with shaft holes that allow the pin shaft body to pass through. When welding, the inner and outer vertical plates cooperate with the tooling to keep the axis of the shaft hole coaxial, thereby improving the flip reliability; the shaft sleeve is welded on the shaft hole of the vertical plate, and precisely matches with the installed flip shaft, so that the cargo box flips smoothly.

[0018] A further improvement of the utility model is that the outer plate of the flip seat is provided with a pin limit assembly for limiting the axial sliding of the pin body. The pin limit assembly effectively prevents the axial movement of the pin body.

[0019] A further improvement of the utility model is that the above-mentioned pin limit assembly includes a limit block installed on the outer plate of the flip seat, and a limit cover plate is detachably installed on the limit block, and a limit flange fixedly connected to the pin body is locked between the limit cover plate and the limit block.

[0020] It can be seen from the above technical scheme that the beneficial effects of the utility model are as follows: the outer vertical plate of the flip seat and the inner vertical plate of the flip seat are separately welded to the bottom surface of the cargo box body, which has high assembly efficiency and avoids the cumbersome installation through bolts and the situation of insufficient preload force caused by negligent operation; because the outer vertical plate of the flip plate and the inner vertical plate of the flip seat are both plate-like structures, they can be directly welded to the cargo box body after processing and forming, reducing the risk of different axes.
