Description

Technical Field

[0001] This utility model relates to the field of cargo loading and unloading, and in particular to a balance beam auxiliary loading and unloading device for emergency supplies out of the warehouse. Background Technology

[0002] Emergency supplies, as an important resource for responding to natural disasters, accidents, public health emergencies, and social security incidents, are widely used in emergency scenarios such as rescue, epidemic prevention and control, and disaster relief. Common emergency supplies include blankets, food, and medical equipment, which are mostly stored in emergency warehouses in the form of boxes or bags. After an emergency occurs, the supplies need to be quickly released from the warehouse, loaded onto vehicles, and transported to the disaster area in a short period of time, which places extremely high demands on loading and unloading efficiency.

[0003] Currently, the outbound and unloading operations of emergency supplies mainly rely on traditional handling tools such as forklifts, handcarts, and lifting platforms, and are mostly manual or semi-mechanized operations. These methods are prone to problems such as shifting center of gravity and uneven force during handling. Especially when multiple people are working together to lift, if there is a mistake in coordination, it is very easy to cause sudden imbalance, resulting in the materials tipping over or sliding down. This may not only cause damage to the packaging and materials, but also pose a safety hazard of injuring the workers, seriously affecting the efficiency of outbound operations and operational safety.

[0004] Therefore, it is necessary to design a balance beam auxiliary loading and unloading device for emergency supplies outbound. Utility Model Content

[0005] In order to overcome the shortcomings of existing loading and unloading methods, such as poor stability and easy tipping of materials, this utility model provides a balance beam auxiliary loading and unloading device for emergency material outbound.

[0006] The technical solution of this utility model is: an auxiliary loading and unloading device for emergency supplies outbound using a balance beam, comprising a base, a controller, a connecting column, a first motor, a mounting beam, an electric push rod, a hook, a lifting rope, a balance beam, a lifting point adjustment structure, and an automatic counterweight structure. A controller is installed on the upper front side of the base. A connecting column is fixedly connected to the center of the upper part of the base. A first motor is installed on the upper side inside the connecting column. A mounting beam is rotatably mounted on the top of the connecting column. The output shaft of the first motor is connected to the rotating shaft of the mounting beam. Electric push rods are installed on both the left and right sides of the mounting beam. Hooks are fixedly connected to the lower telescopic ends of the electric push rods. A balance beam is provided below each hook. A lifting rope is connected between the balance beam and the hook. A lifting point adjustment structure is provided below each balance beam. An automatic counterweight structure is provided above each balance beam. The controller is electrically connected to the first motor and the electric push rod.

[0007] Furthermore, the lifting point adjustment structure includes a U-shaped hanging ring, a mounting screw, and a locking nut. Multiple adjustment holes and slots are evenly spaced on the lower part of the balance beam. U-shaped hanging rings are provided on both the front and rear sides of the lower part of the balance beam. Mounting screws are inserted between the U-shaped hanging rings and the adjacent adjustment holes and slots. Locking nuts are threaded on both the left and right sides of the mounting screws.

[0008] Furthermore, the automatic counterweight structure includes an inclination sensor, an electric slide rail, and a counterweight. An inclination sensor is installed in the middle of the balance beam, and an electric slide rail is installed on the upper part of the balance beam. A counterweight is slidably installed on the electric slide rail. The controller is electrically connected to the inclination sensor and the electric slide rail.

[0009] Furthermore, it also includes support blocks, adjusting screws, second motors, casters, and brake pads. Support blocks are slidably installed on both the front and rear sides of the lower part of the base. Stable holes and slots are opened on both the left and right sides of the lower part of the support blocks. Two adjusting screws are rotatably installed on the right side of the upper part of the base. The adjusting screws are threadedly connected to the support blocks on the same side. Two second motors are installed on one side inside the base. The output shafts of the second motors are connected to the adjacent adjusting screws. Multiple casters are installed on the lower part of the base, and brake pads are installed on each caster.

[0010] Furthermore, the suspension rope is made of high-strength steel wire rope.

[0011] Furthermore, the counterweight is detachably mounted on the electric slide rail. Beneficial effects

[0012] 1. This utility model adopts an electric push rod combined with a lifting rope and a balance beam to achieve smooth lifting and lowering of materials during loading and unloading. At the same time, the lifting point adjustment structure set at the lower part of the balance beam can flexibly adjust the position of the lifting point through the adjustment hole slot to adapt to materials of different sizes and center of gravity distribution, ensuring balanced force during lifting, effectively preventing materials from tipping over, and improving the stability of loading and unloading.

[0013] 2. This utility model has stabilizing holes and slots on the left and right sides of the lower part of the support block. Stabilizing screws can be inserted into muddy, soft or uneven ground to anchor the device to the ground, preventing settlement or slippage during lifting and unloading, and enhancing the stability and safety of operation in complex field environments.

Detailed Implementation

[0019] Example: A balance beam-assisted loading and unloading device for emergency supplies outbound, such as... Figures 1-4 As shown, the system includes a base 1, a controller 2, a connecting column 3, a first motor 4, a mounting beam 5, an electric push rod 6, a hook 7, a lifting rope 8, a balance beam 9, a lifting point adjustment structure, and an automatic counterweight structure. The controller 2 is installed on the upper front side of the base 1. The connecting column 3 is fixedly connected to the center of the upper part of the base 1. The first motor 4 is installed on the upper side of the inside of the connecting column 3 by bolts. The mounting beam 5 is rotatably mounted on the top of the connecting column 3. The output shaft of the first motor 4 is connected to the rotating shaft of the mounting beam 5. Electric push rods 6 are installed on both the left and right sides of the mounting beam 5. Hooks 7 are fixedly connected to the telescopic ends of the lower part of the electric push rods 6. The balance beam 9 is provided below each hook 7. The lifting rope 8 is connected between the balance beam 9 and the hook 7. The lifting rope 8 is made of high-strength steel wire rope, which has good tensile strength and wear resistance, ensuring safety and reliability under long-term high-intensity operation. The balance beam 9 is provided with a lifting point adjustment structure at the bottom and an automatic counterweight structure at the top. The controller 2 is electrically connected to the first motor 4 and the electric push rod 6.

[0020] like Figure 2 and Figure 3 As shown, the lifting point adjustment structure includes a U-shaped hanging ring 10, a mounting screw 11, and a locking nut 12. The lower part of the balance beam 9 is provided with multiple adjustment holes and slots arranged at equal intervals. The lower part of the balance beam 9 is provided with U-shaped hanging rings 10 on both the front and rear sides. The mounting screw 11 is inserted between the U-shaped hanging ring 10 and the adjacent adjustment hole and slot. The left and right sides of the mounting screw 11 are provided with locking nuts 12 threadedly.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, the automatic counterweight structure includes an angle sensor 13, an electric slide rail 14, and a counterweight block 15. An angle sensor 13 is installed in the middle of the balance beam 9, and an electric slide rail 14 is provided on the upper part of the balance beam 9. A counterweight block 15 is slidably installed on the electric slide rail 14. The counterweight block 15 is detachably installed on the electric slide rail 14, which supports the replacement of different specifications of counterweight blocks 15 according to the weight of the materials, thereby enhancing the adaptability and flexibility of the device. The controller 2 is electrically connected to the angle sensor 13 and the electric slide rail 14.

[0022] like Figure 1 and Figure 4 As shown, it also includes a support block 16, an adjusting screw 17, a second motor 18, casters 19, and brake pads 20. The support block 16 is slidably provided on both the front and rear sides of the lower part of the base 1. The supporting block 16 has a stabilizing hole groove on both the left and right sides of the lower part of the supporting block 16. Two adjusting screws 17 are rotatably provided on the upper right side of the base 1. The adjusting screws 17 are threadedly connected to the support block 16 on the same side. Two second motors 18 are installed on one side inside the base 1. The output shafts of the second motors 18 are connected to the adjacent adjusting screws 17. Multiple casters 19 are installed on the lower part of the base 1. Brake pads 20 are installed on each caster 19.

[0023] In actual use, the operator moves the device to the emergency supplies storage area. The base 1 is equipped with multiple casters 19, which facilitates flexible movement and quick positioning of the device in the warehouse. When stable operation is required, the second motor 18 is started, and its output shaft drives the adjusting screw 7 to rotate, causing the support block 16 to extend vertically downwards until it contacts the ground and supports the entire device. At this time, the casters 19 are slightly off the ground to prevent slippage or overturning during loading and unloading. When the device is unloading in complex terrain or on muddy or soft outdoor ground (such as post-disaster temporary resettlement sites or field rescue sites), in order to further improve the stability of the device, the support block 16 has stabilizing slots on both sides. The operator can insert screws through these slots and screw them into the ground to achieve rigid anchoring of the device, effectively preventing the support block 16 from sinking or sliding due to soft ground during the lifting of heavy objects, and significantly enhancing the overall structure's anti-overturning ability.

[0024] After the device is fixed, place the emergency supplies to be hoisted (such as boxed food, medical equipment, or bundles of quilts) directly below the balance beam 9. Start the electric push rod 6 through the controller 2 to control its telescopic end to slowly descend, driving the hook 7 and the hoisting rope 8 to move down, so that the balance beam 9 is lowered to a suitable height. Then, the operator will fix the U-shaped hanging ring 10 by inserting it into the adjustment hole slot through the installation screw 11 and lock the locking nuts 12 on both sides to achieve flexible adjustment of the hoisting point position. According to the length, center of gravity position and packaging form of the materials, a suitable installation position can be selected from the adjustment hole slots arranged at equal intervals at the bottom of the balance beam 9 to ensure that the force on both sides is even and to avoid tilting or shaking during hoisting.

[0025] During lifting, the tilt sensor 13 on the upper part of the balance beam 9 monitors its horizontal status in real time and transmits the signal to the controller 2. If the balance beam 9 tilts due to the shift of the center of gravity of the material, the controller 2 automatically starts the electric slide rail 14, drives the counterweight block 15 to move along the slide rail, and compensates for the mass on the lighter side, realizing dynamic automatic counterweighting to ensure that the horizontal balance is maintained at all times during the lifting process. Throughout the process, the first motor 4 can controllably drive the installation beam 5 to rotate, causing the balance beam 9 to swing left and right in the horizontal plane, realizing directional adjustment in multiple angle ranges, which facilitates the precise positioning and loading of materials. Finally, after the materials are lifted to the top of the transport vehicle, the electric push rod 6 slowly descends and places the materials smoothly into the carriage, completing one loading and unloading operation. The counterweight block 15 is a detachable design, and the appropriate weight of the counterweight block 15 can be replaced according to different weight materials, improving the versatility of the lifting device. The lifting rope 8 is made of high-strength steel wire rope, which has excellent tensile strength and wear resistance, ensuring the safety of lifting.
