Description

Technical Field

[0001] This utility model relates to the field of unloading platform technology, specifically to a sunken unloading platform. Background Technology

[0002] In the cold-mix and cold-lay emulsified asphalt mixing process, the mixing equipment adopts a dual-mixing-cylinder design. The primary and secondary mixing cylinders are arranged vertically and parallel to each other, and a finished product storage silo is set directly below the secondary mixing cylinder. This not only saves space and facilitates overall packaging, but also avoids the quality defects of the produced cold-mixed material being transported to the finished product storage silo via a finished product conveyor belt and then unloaded onto transport vehicles. However, this arrangement makes the discharge port of the finished product storage silo flush with the ground of the site, so a sunken passage needs to be set up to meet the clearance height requirements when vehicles receive the material at the discharge port.

[0003] Currently, when constructing sunken channels in cold-mixed and cold-laid emulsified asphalt storage sites, the space below the discharge port of the cold-mixed and cold-laid emulsified asphalt storage silo is generally completely excavated. While this type of sunken channel allows for convenient receiving and transportation of processed cold-mixed and cold-laid emulsified asphalt by vehicles and enables multiple transport vehicles to easily switch directions for receiving material, the excavation volume during construction is large, significantly increasing the operating cost of the unloading platform. Furthermore, because the bottom of this type of unloading platform is at a fixed height from the discharge port of the cold-mixed and cold-laid emulsified asphalt storage silo, the distance between the transport vehicle's receiving port and the discharge port can easily lead to splashing and waste of cold-mixed and cold-laid emulsified asphalt during the receiving process. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a sunken unloading platform with low construction cost and the ability to adjust the height of the transport vehicle according to the material receiving needs, in light of the current state of the technology.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes a sunken unloading platform, including a sunken tank. A lifting mechanism is installed at the bottom of the sunken tank. The lifting mechanism includes two bottom plates symmetrically installed on both sides of the bottom of the sunken tank, an electric hydraulic rod installed at the top of each bottom plate, a top plate installed at the top of the electric hydraulic rod, and a lifting plate installed on the upper side of the top plate.

[0008] Furthermore, four limiting mechanisms are symmetrically installed on the lifting plate. Each limiting mechanism includes two storage slots opened on the lifting plate, an electric hydraulic rod II installed in the storage slot, and a limiting block installed at the top of the electric hydraulic rod II.

[0009] By adopting the above technical solution, when the wheels of the external transport vehicle are located between the two limiting blocks in each set of limiting mechanisms, the limiting blocks can be raised under the action of the second electro-hydraulic rod so as to limit the wheels of the transport vehicle under the action of the limiting blocks.

[0010] Furthermore, the size of the storage groove is larger than the size of the limiting block, and the limiting block has a wedge-shaped structure.

[0011] By adopting the above technical solution, it can be ensured that the limiting block can be easily retracted into the storage slot.

[0012] Furthermore, the telescopic part of the second electro-hydraulic rod is bolted to the limiting block, and the fixed part of the second electro-hydraulic rod is bolted to the receiving groove.

[0013] By adopting the above technical solution, the lifting and lowering adjustment of the limiting block under the action of the electro-hydraulic rod can be ensured.

[0014] Furthermore, the top plate is bolted to the lifting plate.

[0015] By adopting the above technical solution, a stable connection between the top plate and the lifting plate can be ensured.

[0016] Furthermore, a fixed part of the electro-hydraulic rod is bolted to the base plate, and a telescopic part of the electro-hydraulic rod is bolted to the top plate.

[0017] By adopting the above technical solution, the electro-hydraulic rod is mainly used to realize the convenient lifting of the top plate and the lifting plate.

[0018] Furthermore, one side of the sunken trough is formed with a slope, and anti-slip strips are evenly distributed on the slope.

[0019] By adopting the above technical solution, the ramp can facilitate the smooth entry of external transport vehicles into the bottom of the sunken tank, and the anti-slip strip can ensure that the transport vehicles have sufficient grip when moving on the ramp.

[0020] Furthermore, an operation panel is mounted on one side of the top of the sunken tank via a support rod, and the operation panel is electrically connected to both the first and second electro-hydraulic rods.

[0021] By adopting the above technical solution, the operation panel mainly controls the orderly operation of the first and second electric hydraulic rods by controlling the on and off of the control circuit.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model has the following advantages:

[0024] To address the current practice of constructing sunken channels at cold-mixed emulsified asphalt storage sites, the space below the discharge port of the storage silo is typically completely excavated. While this design allows for convenient loading and unloading of processed cold-mixed emulsified asphalt by vehicles and facilitates easy switching between multiple trucks, the large excavation required during construction significantly increases operating costs. Furthermore, because the bottom of this type of unloading platform is at a fixed height from the discharge port of the storage silo, it can cause issues when trucks are loading, such as the distance between the truck's loading port and the storage silo. The long distance between the discharge port and the cold-mixed emulsified asphalt often leads to splashing and waste during the receiving process. This invention addresses this issue by using a sunken trough and a lifting mechanism installed at the bottom of the sunken trough. This design allows the sunken unloading platform to be used by excavating only the amount of soil matching the sunken trough, facilitating the receiving and transport of cold-mixed emulsified asphalt by transport vehicles. This significantly reduces construction costs. Furthermore, the lifting mechanism allows for height adjustment of the transport vehicle, ensuring a reliable fit between the vehicle's receiving port and the cold-mixed emulsified asphalt discharge port, effectively preventing splashing and waste during the receiving process.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] like Figures 1-3 As shown, a sunken unloading platform in this embodiment includes a sunken trough 1. A lifting mechanism 7 is installed at the bottom of the sunken trough 1. The lifting mechanism 7 includes two base plates 703 symmetrically installed on both sides of the bottom of the sunken trough 1, an electric hydraulic rod 704 installed at the top of each base plate 703, a top plate 701 installed at the top of the electric hydraulic rod 704, and a lifting plate 702 installed on the top plate 701. The electric hydraulic rod 704 is mainly used to facilitate the lifting of the top plate 701 and the lifting plate 702. After the lifting plate 702 is lifted, the height of the transport vehicle can be adjusted, which can ensure that the receiving port of the transport vehicle and the discharge port of the cold-mixed cold-laid emulsified asphalt can be reliably fitted, effectively avoiding the splashing and waste of cold-mixed cold-laid emulsified asphalt during the receiving process.

[0032] like Figures 1-3 As shown in this embodiment, four limiting mechanisms 6 are symmetrically installed on the lifting plate 702. Each limiting mechanism 6 includes two storage slots 601 opened on the lifting plate 702, an electric hydraulic rod 603 installed in the storage slot 601, and a limiting block 602 installed at the top of the electric hydraulic rod 603. When the wheels of the external transport vehicle are located between the two limiting blocks 602 in each set of limiting mechanisms 6, the limiting blocks 602 can be lifted under the action of the electric hydraulic rod 603 so as to limit the wheels of the transport vehicle under the action of the limiting blocks 602.

[0033] like Figures 1-3 As shown, in this embodiment, the size of the storage groove 601 is larger than the size of the limiting block 602. The limiting block 602 has a wedge-shaped structure, which can ensure that the limiting block 602 can be easily retracted into the storage groove 601. The telescopic part of the second electric hydraulic rod 603 is bolted to the limiting block 602, and the fixed part of the second electric hydraulic rod 603 is bolted to the storage groove 601, which can ensure that the limiting block 602 can be easily raised and lowered under the action of the second electric hydraulic rod 603.

[0034] like Figures 1-3 As shown, in this embodiment, the top plate 701 and the lifting plate 702 are bolted together to ensure a stable connection between the top plate 701 and the lifting plate 702. The fixed part of the electric hydraulic rod 704 is bolted to the bottom plate 703, and the telescopic part of the electric hydraulic rod 704 is bolted to the top plate 701.

[0035] like Figures 1-3As shown in this embodiment, a ramp 2 is formed on one side of the sunken tank 1, and anti-slip strips 3 are evenly distributed on the ramp 2. The ramp 2 facilitates the smooth entry of external transport vehicles into the bottom of the sunken tank 1, while the anti-slip strips 3 ensure that the transport vehicles have sufficient grip when moving on the ramp 2. An operation panel 5 is installed on one side of the top of the sunken tank 1 through a support rod 4. The operation panel 5 is electrically connected to the first electric hydraulic rod 704 and the second electric hydraulic rod 603. The operation panel 5 mainly controls the orderly operation of the first electric hydraulic rod 704 and the second electric hydraulic rod 603 by controlling the on and off of the control circuit.

[0036] The specific implementation process of this embodiment is as follows: First, the sunken trough 1 is installed in a pre-drilled trough at the outlet of the cold-mixed emulsified asphalt storage bin. The unloading platform is then connected to an external power source and control components. Next, the transport vehicle is moved via the ramp 2 onto the lifting plate 702 and limited by the limiting mechanism 6. This allows for convenient discharge of the cold-mixed emulsified asphalt stored in the storage bin onto the transport vehicle. During the receiving process, the lifting mechanism 7 is used to adjust the height of the transport vehicle, ensuring a reliable fit between the receiving port and the outlet of the cold-mixed emulsified asphalt. This effectively prevents the splashing and waste of the cold-mixed emulsified asphalt during receiving. Furthermore, the sunken unloading platform only requires excavation of soil matching the volume of the sunken trough 1, facilitating the transport vehicle's receiving and transport of the cold-mixed emulsified asphalt while reducing the amount of excavation required during platform deployment, significantly reducing construction costs.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
