Description

Technical Field

[0001] The invention relates to the technical field of open-pit mines, and in particular to a high-section earth removal protection device suitable for open-pit mines. Background Art

[0002] In the soil stripping operation of open-pit mines, the stripped soil and rocks usually need to be transported by truck to the spoil dump for accumulation. The spoil dump is generally composed of multiple spoil layers, each of which is formed by dumping and rolling soil by heavy-loaded trucks. As the operation progresses, the ground of the spoil dump may become soft, especially in some wet or sandy areas, where the soil is particularly soft. In this case, when the truck enters the spoil slope, the wheels can easily sink into the soft soil layer, causing the vehicle to be unable to pass smoothly or to roll over. Rollovers will not only cause damage to the truck and delay transportation, but may also cause safety hazards in the soil transportation process and even affect the efficiency of the entire spoil operation.

[0003] After searching, the public (announcement) number: CN218666975U discloses a safety protection device for open-pit mine soil discharge construction, including a soil discharge layer and a soil discharge slope. Rectangular placement grooves are opened at the four corners of the upper end of the soil discharge layer. The adjustment mechanism includes a fixed block. The four fixed blocks are respectively fixedly installed in the four accommodating grooves. The upper ends of the four fixed blocks are fixedly installed with external threaded columns. The four external threaded columns are respectively slidably arranged in two strip grooves. The surfaces of the four external threaded columns are threaded with internal threaded disks. The four internal threaded disks are respectively located above the two U-shaped frames. The support position of the heavy-loaded truck will be effectively adjusted under the movement of the bearing plate, so that it can effectively prevent the heavy-loaded truck from sinking into the soil discharge layer with soft soil, thereby enhancing the safety protection effect. Moreover, through the design of the compaction block, the contact area between the U-shaped frame and the soil discharge layer is increased accordingly, so that the equipment is not easy to slip during installation, further enhancing the stability of the equipment.

[0004] In the above-mentioned prior art solutions, the load-bearing plate needs multiple screws to be fixed. This fixing method is complicated and time-consuming during the disassembly and assembly process, which not only increases the difficulty of manual operation but also reduces the overall work efficiency. In addition, frequent screw removal and installation may cause the screws to wear or be damaged, further affecting the service life and safety of the equipment.

[0005] Therefore, we propose a high-level spoil protection device suitable for open-pit mines. Summary of the invention

[0006] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a high-level earth removal protection device suitable for open-pit mines.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme, a kind of earth discharge protection device suitable for the high section of open-pit mine, including an earth discharge plate and a support plate, the earth discharge plate is provided with a weight-reducing groove, one side of the earth discharge plate is fixedly connected with a reflective plate, plug plates are fixed on both sides of the bottom of the support plate, slots are provided on the top of the earth discharge plate, the plug plate and the earth discharge plate are respectively provided with a first positioning hole and a second positioning hole, installation frames are fixed on both sides of the earth discharge plate, through holes and limit grooves are respectively provided on both sides of the installation frame, pull rods are slid in the through holes, pull rings and limit plates are respectively fixed at both ends of the pull rods, reset springs are sleeved on the pull rods, and limit rods are passed through the limit grooves.

[0008] Preferably, storage cavities are provided at the four end points of the bottom of the earthmoving plate, the bottom of the inner cavity of the storage cavity is fixedly connected to a hydraulic cylinder, and the protruding ends of the hydraulic cylinder are equipped with universal wheels.

[0009] Preferably, installation handles are fixedly connected to the centers of both sides of the support plate.

[0010] Preferably, the limiting groove, the limiting rod, the second positioning hole and the first positioning hole are all T-shaped structures and are adapted to each other.

[0011] Preferably, one end of the limiting rod close to the limiting plate is fixedly connected to the limiting plate, and the upper and lower wall surfaces of the limiting plate are in contact with the upper and lower wall surfaces of the inner cavity of the installation frame.

[0012] Preferably, the pull ring is located at one end of the outer side of the installation frame, and the return spring is located in the inner cavity of the installation frame.

[0013] Preferably, the first positioning hole is opened at the center of the two plug boards, and the second positioning hole is matched with the first positioning hole.

[0014] The present invention provides a protective device for high-level dumping in open-pit mines. It has the following beneficial effects:

[0015] 1. This device is suitable for high-section earth discharge protection in open-pit mines. Through the cooperation of the pull ring, the reset spring, the limit plate, the limit rod, the first positioning hole and the second positioning hole, the support plate can be quickly and conveniently disassembled from the earth discharge plate, thereby greatly simplifying the disassembly and assembly process, which not only reduces the time of manual operation, but also improves the overall work efficiency, providing higher convenience and safety for open-pit mine operations.

[0016] 2. This is a protective device suitable for high-level soil discharge in open-pit mines. Through the cooperation of the storage chamber, hydraulic cylinder and universal wheel, the protective device can be quickly moved to the designated position when needed, effectively reducing the need for manual handling. The driving action of the hydraulic cylinder provides strong power support, while the flexibility of the universal wheel ensures that the device can be easily moved in a complex mining environment, which not only improves the flexibility of the device, but also enables the device to be efficiently dispatched and adjusted according to different operating requirements during the high-level soil discharge process in the open-pit mine, thereby improving operating efficiency and safety.

[0017] 3. This type of protective device is suitable for high-level dumping in open-pit mines. By setting up a reflective plate, it can remind the driver that he cannot retreat backwards, thus ensuring driving safety.

[0018] 4. This type of device is suitable for high-section earth discharge protection in open-pit mines. By installing a handle, it is convenient to pick up and put down the support plate.

[0019] 5. This type of device is suitable for high-section earth removal protection in open-pit mines. By setting multiple ground spikes around the bottom of the earth removal plate, the ground spikes can penetrate deep into the ground during the installation process to provide additional fixing force for the device, ensuring that it will not be displaced or tilted due to environmental changes or external forces during high-section earth removal operations, thereby ensuring its reliability and durability under various operating conditions.
