Description

Technical Field

[0001] This utility model relates to the field of mining dump truck technology, specifically a side-discharge structure for an underground mining dump truck. Background Technology

[0002] Underground mining is a core component of global mining production, providing crucial raw materials for numerous industrial sectors, such as steel and non-ferrous metals. In the complex process of underground mining, dump trucks, as key transportation equipment, play a vital role in efficiently and safely transporting mined ore from the mining face to surface or underground storage bins. Their performance directly determines the overall production efficiency and cost of the mining operation. To overcome the limitations of rear-discharge structures, side-discharge structures are increasingly being applied to underground dump trucks.

[0003] The side-discharge structure allows ore to be dumped to the side by opening one side of the truck body. However, the truck body is designed as a single unit, which makes it impossible to independently rotate and flip each part of the truck body. This can easily lead to uneven ore discharge and longer unloading time. Furthermore, during the side-discharge process, the center of gravity of the truck body shifts, and the existing side-discharge structure lacks effective support and stabilization devices, which can easily lead to safety accidents such as vehicle rollover. Therefore, this utility model provides a side-discharge structure for an underground ore dump truck. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a side-dumping structure for an underground ore dump truck. This solves the problem that while side-dumping structures allow ore to be dumped to the side by opening one side of the truck bed, the integrated design of the truck bed makes it impossible to independently rotate and flip each part of the truck bed. This can easily lead to uneven ore discharge, longer unloading time, and the lack of effective support and stabilization devices in existing side-dumping structures due to the shift in the center of gravity of the truck bed during the side-dumping process, which can easily lead to safety accidents such as vehicle rollover.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a side-discharging structure for an underground mining dump truck, comprising a movable base, wherein a side-discharging mechanism for the underground mining dump truck is provided on the movable base, and the side-discharging mechanism includes:

[0006] The side-discharge assembly includes a first carriage connected to the upper surface of a movable base via a first pushing assembly, connecting shafts on both sides of the upper end of the first carriage, and a second carriage connected to the outer wall of the connecting shaft via a second pushing assembly.

[0007] The support assembly includes a fixing rod fixed to the side wall of the first carriage, the fixing rod having a first support wheel connected by a telescopic assembly inside, and a locking assembly for fixing to the first carriage being provided on one side of the movable base.

[0008] Preferably, the first jacking assembly includes a first hydraulic rod rotatably connected at both ends of the upper surface of the movable base via a rotating shaft. Connecting blocks are uniformly fixed on the side wall of the movable base. The first carriage is mounted on the connecting blocks via a rotating shaft. The telescopic end of the first hydraulic rod is rotatably connected to the first carriage. The second jacking assembly includes a fixing block fixed to the side wall of the first carriage. A third hydraulic rod is rotatably connected to the side wall of the fixing block via a rotating shaft. The second carriage is rotatably connected to the outer wall of the connecting shaft. The telescopic end of the third hydraulic rod is rotatably connected to the side wall of the second carriage via a rotating shaft.

[0009] Preferably, the telescopic assembly includes a fixing rod fixed to the side wall of the first carriage, a second hydraulic rod being fixed through the inside of the fixing rod, and the first support wheel being located at the telescopic end of the second hydraulic rod.

[0010] Preferably, the locking assembly includes a locking bracket fixed to the side wall of the movable base, a locking plate fixed to the side wall of the first carriage and fitting against the upper end face of the locking bracket, and locking bolts for locking are provided inside the locking plate and the locking bracket.

[0011] Preferably, a fixed bracket is fixed to one side of the lower end face of the first carriage, and a second support wheel is provided at the lower end of the fixed bracket.

Beneficial effects

[0013] This utility model provides a side-discharge structure for an underground mining dump truck. Compared with the prior art, it has the following advantages:

[0014] Firstly, when side unloading is required, this utility model first activates the first hydraulic rod, whose telescopic end extends. Since it is rotatably connected to the first carriage, it pushes the first carriage to rotate upward around the rotation axis on the connecting block, realizing the side unloading and pushing operation of the first carriage. Then, the third hydraulic rod is activated, and its telescopic end extends. Since it is rotatably connected to the side wall of the second carriage, it pushes the second carriage to rotate around the connecting shaft, causing the second carriage to open and separate from the first carriage. The ore can then be smoothly discharged from the gap. Through the coordinated action of the first and second pushing components, the ore can be quickly and effectively unloaded from the side of the carriage. Compared with the traditional unloading method, the unloading time is greatly shortened, the overall operation efficiency is improved, and independent control of the first and second carriages is achieved, making the unloading process more flexible. The opening and closing separation design of the second and first carriages makes the discharge of ore more convenient.

[0015] Secondly, the first support wheel in the telescopic assembly of this utility model provides support when the first carriage is unloaded from the side, effectively preventing the first carriage from overturning due to the shift of the center of gravity, thus improving the safety of the unloading process. The locking assembly firmly locks the first carriage during transportation, ensuring the stability of the vehicle during transportation and reducing safety hazards caused by carriage shaking. At the same time, the positioning blocks that are evenly fixed on the upper surface of the movable base cooperate with the positioning slots on the lower surface of the support frame of the first carriage. When the first carriage is placed on the movable base, the positioning slots can accurately engage with the positioning blocks, playing a role in positioning and fixing, and preventing the first carriage from shaking and shifting during transportation.
