Abstract
Description
Technical Field
[0001] This utility model relates to the field of rear-tilting seat technology, and in particular to a rear-tilting seat structure and its wide-body mining dump truck. Background Technology
[0002] The rear tipping seat is a tipping device at the rear of the cargo box of a wide-body mining dump truck, used to enable the cargo box to tip over, thereby facilitating unloading.
[0003] Rear tilt seats typically require high load-bearing capacity. Traditional rear tilt seats usually use thicker steel plates to increase the load-bearing limit, but the lateral torsional resistance between the two ends of the rear tilt seat is not reinforced. After long-term use, this may cause deformation at both ends of the rear tilt seat, resulting in uneven tilting. In addition, traditional rear tilt seats are fixed to the frame by welding, which requires a high level of skill from the welders. Otherwise, incomplete welding will seriously affect the load-bearing capacity and stability of the rear tilt seat.
[0004] Therefore, those skilled in the art have provided a rear-tilting seat structure and a wide-body mining dump truck thereof to solve the problems mentioned in the background art. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a rear-tilting seat structure and its wide-body mining dump truck, solving the problems mentioned in the background art.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] A rear-flipping seat structure includes: a flipping seat body, the flipping seat body being U-shaped, the front end of the flipping seat body being ground into an arc shape; an inner reinforcement structure, the inner reinforcement structure being disposed within the cavity of the flipping seat body, the inner reinforcement structure including a reinforcing rod and a reinforcing rib; an outer reinforcement structure, the outer reinforcement structure being disposed on the outer wall surface of the flipping seat body, the outer reinforcement structure including a supporting steel plate; and mounting components, the mounting components being disposed on both outer walls of the flipping seat body, the mounting components including a limiting part and a connecting rod.
[0008] According to the aforementioned rear-flipping seat structure, through holes are provided on both sides of the inner wall of the flipping seat body, and multiple reinforcing ribs are welded and fixed to the bottom wall of the flipping seat body cavity.
[0009] According to the aforementioned rear-flipping seat structure, the reinforcing rod is X-shaped and is welded and fixed between the two side walls inside the cavity of the flipping seat body. The reinforcing rod is located above the reinforcing rib.
[0010] According to the aforementioned rear-flipping seat structure, there are two supporting steel plates, which are hollow triangular frames. The two supporting steel plates are fixed to the flipping seat body by welding, and the two supporting steel plates are symmetrical around the flipping seat body.
[0011] According to the rear flip-up seat structure, the outer walls on both sides of the flip-up seat body that are far apart from each other are provided with engagement grooves, and multiple engagement grooves form an "L" shape.
[0012] According to the rear flip seat structure, one end of the connecting rod can be inserted into the engaging groove. The limiting part includes a stop block and a limiting plate. The stop block and the limiting plate are fixedly connected. A groove is provided on one side of the limiting plate. The end of the connecting rod away from the engaging groove can be inserted into the groove. The limiting plate and the flip seat body can be fixed by welding.
[0013] A wide-body mining dump truck includes a frame and a rear tipping seat structure as described above.
[0014] According to the wide-body mining dump truck, the rear tipping seat structure is welded and fixed to the frame.
[0015] According to the wide-body mining dump truck, studs are welded and fixed on the frame, and the rear tipping seat structure is fixed to the frame by studs and nuts.
[0016] This utility model provides a rear-tilting seat structure and its wide-body mining dump truck. It has the following beneficial effects:
[0017] (1) By setting the flip seat body to be U-shaped, the internal reinforcement structure in the cavity of the flip seat body can improve the lateral tensile force at both ends of the flip seat body and make it less prone to deformation. By setting the external reinforcement structure on the outer wall of the flip seat body, the structure of the flip seat body is further reinforced, and the stability is higher. The flip seat body can be directly welded and fixed to the frame. By setting the mounting components, the flip seat body can also be fixed to the frame by the mounting components through the thread, making disassembly and replacement more convenient.
[0018] (2) By setting the reinforcing rod in an “X” shape, the reinforcing rod is welded and fixed between the two side walls inside the cavity of the flip seat body. The two ends of the reinforcing rod are fixed to the two ends of the U shape respectively, which increases the upper limit of the lateral tensile force at both ends of the flip seat body, thereby increasing the upper limit of the load. By fixing and installing the support steel plate on both sides of the flip seat body, the support steel plate is triangular, which further improves the stability of the device. The support steel plate is welded and fixed to the flip seat body, which can reinforce the flip seat body and increase the upper limit of the load of the flip seat body.

One end of the connecting rod is inserted into the engagement groove. A groove is opened on the limiting plate. The other end of the connecting rod is inserted into the groove. The limiting plate and the flip seat body can be fixed by welding. The limiting plate is fixedly connected to the stop block. The stop block is fixed on the frame by studs and nuts, which facilitates installation and disassembly. The flip seat body can also be directly welded to the frame. The two installation methods further improve the practicality of this application. Attached Figure Description
