Description

Technical Field

[0001] This invention belongs to the field of open-pit mine spoil disposal construction technology, and specifically relates to safety protection devices for open-pit mine spoil disposal construction. Background Technology

[0002] Nowadays, during the construction of open-pit mine spoil heaps, vehicles are needed to strip the soil layers. Because there are many layers of spoil heaps, and the soil in these layers is relatively loose, vehicles can easily sink in during driving, causing the wheels to get stuck and preventing them from driving normally.

[0003] Currently, a utility model patent with patent number CN202021069946.0 discloses a safety protection device for open-pit mine spoil disposal construction, including a spoil disposal layer and a spoil disposal slope. A supporting base plate is installed on the top of the spoil disposal layer, adjacent to the spoil disposal slope. An integral stop block is installed on the supporting base plate near the spoil disposal slope. Several rows of strip-shaped holes are opened on the supporting base plate, and a strip-shaped groove is opened between every two adjacent rows of strip-shaped holes on the top of the supporting base plate. This utility model, by setting a supporting base plate on the spoil disposal layer adjacent to the spoil disposal slope, and fixing the supporting base plate with a fixing rod at the bottom of a cover plate, serves to support heavy-duty trucks, preventing them from sinking into the loose soil of the spoil disposal layer and ensuring the efficiency of open-pit mine spoil disposal. However, the device in this application cannot guarantee the flatness of the device. Due to the overall light weight of the device, the middle part of the device is prone to sinking downwards during vehicle movement, causing the left and right ends to lift up, leaving gaps between the device and the soil layer, which can easily affect the construction safety of surrounding workers.

[0004] Therefore, the problem that the above-mentioned device cannot guarantee the flatness of the device urgently needs to be solved in order to improve the usage scenarios of the device. Summary of the Invention

[0005] (1) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a safety protection device for open-pit mine spoil disposal construction. This device aims to solve the technical problem that the existing technology cannot guarantee the flatness of the device, and that the middle part of the device is prone to sinking downwards during vehicle travel due to the light weight of the device.

[0007] (2) Technical solution

[0008] To address the aforementioned technical problems, this invention provides a safety protection device for open-pit mine spoil disposal construction. The device includes a fixed frame, an installation component positioned below the fixed frame for positioning, a protective plate positioned above the fixed frame for protection, and a height adjustment component positioned above the protective plate for height adjustment. The fixed frame surface has uniformly distributed first through grooves, a downward-recessed groove at the front of the first through groove, an elastic element that can stretch and retract elastically inside the groove, and a shielding component above the elastic element to prevent vehicles from falling off.

[0009] When using the device of this technical solution, first place the entire device on the spoil layer in the open-pit mine spoil heap, and then press the entire device downwards so that the mounting components on the lower side of the fixing frame can penetrate into the spoil layer. When the lower end face of the fixing frame is aligned with the spoil layer, lift the height adjustment component upwards as needed and adjust it to the appropriate position. Then, glue the shielding component to the elastic element inside the fixing frame. When the vehicle runs over the shielding component, it can indicate to the driver that it can no longer reverse, thus preventing the driver from moving backwards and ensuring that the vehicle will not fall off the fixing frame. The height adjustment component can fix the... The left and right sides of the frame are pressed down to ensure that the entire fixed frame is flush with the soil layer. The protective plate and height adjustment component can protect the vehicle from both sides to prevent it from overturning. At the same time, the protective plate and height adjustment component have a certain weight, which can press the left and right sides of the fixed frame down to keep the fixed frame flush with the soil layer and prevent gaps between the fixed frame and the soil layer. This prevents construction workers from getting stuck in the gaps during construction, thus avoiding affecting the construction safety of surrounding workers. The installation component can firmly fix the fixed frame to the soil layer to prevent the device from shifting later.

[0010] Preferably, the mounting assembly includes a mounting plate, and the lower side of the mounting plate is provided with positioning cones for positioning, the positioning cones being evenly distributed on the lower side of the mounting plate. The positioning cones allow the mounting plate to extend downwards into the soil discharge layer, ensuring the mounting plate is firmly fixed within the soil discharge layer, making positioning and installation very convenient.

[0011] Furthermore, the mounting plate has a second through groove on its surface to increase friction, and the second through groove is evenly distributed on the surface of the mounting plate. By providing the second through groove, some space can be reserved for the soil in the soil discharge layer during the downward pressing of the mounting plate, allowing the soil to overlap with the mounting plate.

[0012] Furthermore, the height adjustment assembly includes a movable rod, and a connecting rod for connecting the protective plate is provided on the lower side of the movable rod. Through the connecting rod, it can be connected to the protective plate, allowing the entire height adjustment assembly to form a single unit with the protective plate, applying a certain pressure to both sides of the fixed frame.

[0013] Furthermore, the protective plate has a groove on its surface for fixing the connecting rod, and a limiting groove inside the groove to prevent the connecting rod from falling off. A limiting block corresponding to the limiting groove is provided on the outside of the connecting rod. Through the cooperation between the limiting block and the limiting groove, the connecting rod can be ensured to always move on the protective plate and will not fall off, making the entire structure more stable.

[0014] Furthermore, the movable rod has protrusions at both the front and rear ends for outward projection, and ball heads on the outer sides of these protrusions for scratch prevention. The ball heads prevent scratches to nearby construction workers and also avoid cracks or other damage to construction tools upon impact.

[0015] Furthermore, the shielding component includes a baffle strip with a reflective strip on its upper side and a limiting frame corresponding to the groove on its lower side. The baffle strip serves to indicate that the vehicle can no longer reverse and also blocks the wheels to prevent them from rolling, thus preventing the vehicle from falling off the road.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The device of the present invention, through the setting of the protective plate and the height adjustment component, can protect the vehicle from both sides to prevent the vehicle from overturning. At the same time, the protective plate and the height adjustment component have a certain weight, which can press the left and right sides of the fixing frame downward, so that the fixing frame can be flush with the soil layer, avoiding the formation of gaps between the fixing frame and the soil layer, so that construction workers will not get stuck in the gaps during construction, thereby avoiding affecting the construction safety of surrounding construction workers. Through the setting of the installation component, the fixing frame can be firmly fixed to the soil layer, preventing the device from shifting later. Attached Figure Description
