Description

Technical Field

[0001] This utility model belongs to the field of river flood control and emergency rescue technology, and in particular relates to a mobile gabion non-destructive loading and unloading vehicle. Background Technology

[0002] In flood control and river regulation projects along the Yellow River, gabions are widely used for bank protection and slope stabilization due to their structural stability and high construction efficiency. Traditional gabion fabrication employs the "pit method," where rescue workers use excavators to dig pits in flat ground, lay gabion mesh, fill them with stones, seal the openings, and then the excavator removes the gabions and transports them to the affected section of the dike for placement. However, this process has significant drawbacks: firstly, it demands extremely high skill from excavator operators, as even slight mistakes can damage the wire mesh; secondly, the pit dimensions are difficult to standardize, leading to large fluctuations in stone filling fullness and affecting structural stability; most importantly, the wire breakage rate is as high as 30% when the excavator bucket teeth directly dig up the gabions, and further damage occurs during placement due to the loose gabion structure. Statistics show that the wire breakage rate is directly related to the stone filling fullness; insufficient fullness significantly increases the risk of placement damage. Summary of the Invention

[0003] To address this industry challenge, this utility model focuses on two key breakthroughs: reducing mechanical damage and improving the standardization of gabion loading. Through repeated experiments, a mobile gabion loading vehicle with non-destructive loading was successfully developed. Standardized material bins and standardized gabions ensure that the gabion filling fullness remains consistently within a precision range of ±3%. Experiments show that the new technology reduces the production time of a single gabion by nearly half and increases the throwing integrity rate from 70% to nearly 100%.

[0004] The objective of this utility model is achieved through the following technical solution: A mobile gabion non-destructive loading and unloading vehicle includes a frame, with a pivot hinged at one end of the frame and wheels mounted on the bottom of the other end. A material box is mounted on the top of the other end of the frame. The two sides of the frame are side frames, and the material box is hinged to the top of the side frame near the wheel end. The material box is inverted conical. An electric push rod is mounted on the frame inside the side frame. The telescopic end of the electric push rod is hinged to the bottom of the material box. The electric push rod is connected to an electrical controller.

[0005] The aforementioned mobile gabion non-destructive loading and unloading vehicle also includes a material box sleeve rod and a material box connecting plate. Two material box connecting plates with sleeve holes are provided at the bottom of the material box. After the material box sleeve rod passes through the sleeve holes of the two material box connecting plates, both ends are fixed to the top of the corresponding side frame. The material box connecting plate can rotate around the material box sleeve rod under the action of an electric push rod.

[0006] In the aforementioned mobile gabion non-destructive loading and unloading vehicle, there is a 1-3mm gap between the sleeve rod of the material box and the sleeve hole on the connecting plate of the material box.

[0007] The aforementioned mobile gabion non-destructive loading and unloading vehicle is equipped with two push rod connecting plates at the bottom of the material box, and two electric push rods are correspondingly installed on the vehicle frame. The telescopic ends of the two electric push rods are respectively hinged to the corresponding push rod connecting plates.

[0008] The aforementioned mobile gabion non-destructive loading and unloading vehicle has a rotating hole at the telescopic end of the electric push rod. After the push rod sleeve passes through the rotating holes of the two electric push rods, both ends are fixed to the corresponding push rod connecting plates. The push rod sleeve can rotate in the rotating holes of the electric push rods.

[0009] The aforementioned mobile gabion non-destructive loading and unloading vehicle has an elastic element installed on the frame between the electric push rod and the pin shaft, with the top of the elastic element contacting the bottom of the hopper.

[0010] In the aforementioned mobile gabion non-destructive loading and unloading vehicle, the elastic element is a spring, with the bottom of the spring fixed to the vehicle frame and the top contacting the bottom of the material box.

[0011] Compared with the prior art, the present invention has the following technical effects: The feed bin of this utility model's wire mesh loading vehicle adopts an inverted conical design, without sharp edges, so it will not cut the wire mesh. This facilitates the spreading of the wire mesh, allowing it to fit snugly against the bin wall and preventing the wires from being cut by the pressure of stones. The use of a bucket for loading allows for precise control of the loading saturation. This improves the standardization of operations, increases labor efficiency, significantly reduces the wire mesh breakage rate, lowers rescue costs, and greatly enhances the overall effectiveness of rescue operations.

[0012] The experiment significantly reduced the overall cost of emergency rescue. Material consumption: Traditional wire mesh cages need to be replaced frequently due to mechanical damage, with an annual consumption of 80,000 cubic meters (according to statistics from the Ministry of Water Resources in 2023). However, by adopting non-destructive technology, material consumption can be greatly reduced. Human resource input: Damage repair requires additional manpower for mesh patching operations, while with non-destructive technology support, no additional mesh patching personnel are needed; Ecological cost: Excessive zinc ion concentration (>2mg / L) released from damaged wire mesh cages can poison aquatic organisms, while non-destructive loading and unloading technology is beneficial to environmental protection.

[0013] A complete gabion system can form a topologically interlocking protective net, and its resistance to displacement is 3.2 times that of a single gabion (simulation data from the Yellow River Institute of Hydraulic Research). After the gabions are installed and deployed without damage, their protective capacity for dams will also be greatly improved. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] like Figure 1-2 As shown, a mobile gabion non-destructive loading and unloading vehicle includes a frame 8, with a hinged pin 9 at one end of the frame, a wheel 1 mounted on the bottom of the other end of the frame, and a material box 5 mounted on the top of the other end of the frame. The two sides of the frame 8 are side frames 2, and the material box 5 is hinged to the top of the side frame near the wheel end. The material box is inverted conical. An electric push rod 7 is mounted on the frame inside the side frame. The telescopic end of the electric push rod is hinged to the bottom of the material box, and the electric push rod is connected to an electrical controller.

[0021] In flood control and disaster relief operations, this utility model is used in conjunction with an excavator. The utility model is connected to the excavator via a pin, and the excavator carries it to the disaster relief site. Rescue personnel then lay wire mesh sheets on the material box of this utility model. The material box is designed in an inverted cone shape to facilitate a close fit between the wire mesh sheets and the box. After the wire mesh sheets are laid, the excavator loads stones into the material box to the preset load amount, and then seals the wire mesh sheets to form a gabion. The excavator then transports this utility model to the disaster relief location, and the electric push rod is remotely operated. Figure 3 or Figure 4 As shown, when the electro-hydraulic actuator extends, the material box rotates around the hinge point. When it reaches a certain angle, the gabion slides out of the material box and falls to the dangerous position.

[0022] This utility model features a chassis and wheels forming the walking mechanism. The material box is mounted on the chassis using a hinged connection, allowing it to rotate around the hinge point. The rotation of the material box is powered by an electric actuator, with its head hinged to the material box and its tail hinged to the chassis. The electro-hydraulic actuator uses a 24-volt power supply, which can be drawn from the excavator's power interface, eliminating the need for a separate power source. Compared to using a conventional hydraulic cylinder, this design eliminates the need for a hydraulic station, significantly reducing costs. The electric actuator is equipped with a wireless remote control switch, allowing for remote operation and greatly improving safety.

[0023] The mobile gabion loading and unloading vehicle of this utility model also includes a material box sleeve rod 10 and a material box connecting plate 3. Two material box connecting plates 3 with sleeve holes are provided at the bottom of the material box. After the material box sleeve rod passes through the sleeve holes of the two material box connecting plates, both ends are fixed to the top of the corresponding side frame 2. The material box connecting plate can rotate around the material box sleeve rod under the action of an electric push rod. This utility model also provides two push rod connecting plates 4 at the bottom of the material box, and correspondingly installs two electric push rods on the frame. The telescopic ends of the two electric push rods are hinged to the corresponding push rod connecting plates. This utility model symmetrically arranges two electric push rods, and both electric push rods are installed on the material box sleeve rod. This design makes the force on the material box more balanced when rotating under the action of the material box sleeve rod, increasing safety and reliability.

[0024] The mobile gabion loading and unloading vehicle of this utility model has a 1-3mm gap between the sleeve rod of the material box and the sleeve hole on the material box connecting plate. When the material box is running smoothly, it is supported on the material box connecting plate, and during emergency rescue, it is convenient for the material box to rotate around the material box connecting plate.

[0025] The mobile gabion loading and unloading trolley of this invention features rotating holes at the telescopic ends of the electric push rods. The push rod sleeve 11 passes through the rotating holes of two electric push rods, and its two ends are fixed to the corresponding push rod connecting plates. The push rod sleeve can rotate through the rotating holes of the electric push rods. The force from the two electric push rods acts evenly on the push rod sleeve, and then acts on the material box through the push rod sleeve, thereby improving the balance during rotation and increasing safety and reliability.

[0026] The mobile gabion loading and unloading trolley of this utility model features an elastic element 6 installed on the frame between the electric push rod and the pin shaft. The top of the elastic element contacts the bottom of the material box. The elastic element is a spring, with its bottom fixed to the frame and its top in contact with the bottom of the material box. This design buffers vibrations during stone loading, prevents frequent pressure impacts on the electric push rod, and extends its service life.

[0027] The research and development experimental data of this utility model are as follows: Combination Figure 1 and Figure 3When the electric actuator pushes the hopper, the direction of the thrust changes little, with an angle of approximately 67 degrees to the horizontal. The hopper itself weighs 1500 kg, and the gabion basket, when fully filled and sealed, weighs approximately 5000 kg, for a total weight G = 6500 kg. Conservatively estimating the center of gravity to fall 200 mm from the rotating hinge point, based on the principle of torque balance, the gravitational torque and the thrust torque are equal, leading to the following equation: G×200=T×200×sin67° The calculated thrust of the electric actuator is T = 69201N. Considering mechanical energy loss and a certain margin, the thrust T is taken as 80000N. There are two electro-hydraulic actuators, each with a thrust of 40000N, which serves as the basis for selection.

[0028] The frame of this utility model has a certain length and is hinged to the excavator, thus extending the excavator's working radius. For example... Figure 4 As shown, this utility model can operate on slopes, can place stones more accurately, improve the efficiency and quality of emergency rescue, and expand the capabilities of excavators.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
