Description

[0001] This is a divisional application of the invention titled "Self-stabilizing Device, Bucket with Self-stabilizing Device, and Self-stabilizing Method for Bucket" (Application No.: 2021113071363; Application Date: November 5, 2021). Technical Field

[0002] The present invention belongs to the technical field of anti-sway and stability enhancement of buckets, and particularly relates to a self-stabilizing method for a bucket. Background Art

[0003] Nowadays, when constructing large-scale water conservancy projects to improve the efficiency of concrete pouring, concrete is often transported by a cable crane. When affected by strong wind environments, such as the annual wind force level at the Baihetan Hydropower Station being grade 7 - 9, the concrete bucket on the cable crane often sways from side to side. This situation not only affects the safety of construction but also reduces the efficiency of unloading concrete. Currently, the common method to solve this phenomenon is to passively prevent collisions, such as tying old tires around the tank body, and there are also some active solutions, such as setting up jets, but this method has a complex structure, high energy consumption, and poor practicality. Some new concrete bucket safety devices, such as the "Concrete Bucket Anti-falling Safety Protection Device" disclosed in Chinese Patent Document CN213505561U, make the concrete bucket have a strong bearing capacity, can prevent the bucket from falling off during the concrete pouring process, and have relatively high safety. However, when the cable crane is transporting concrete, especially during high-altitude operations in strong wind weather, it is inevitable for the bucket to sway from side to side. There is still no simple and practical method to solve this problem and keep the bucket balanced. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the self-stabilizing method for a bucket provided by the present invention solves the problem of the concrete bucket swaying during transportation by the cable crane due to the influence of strong wind weather. The present invention applies the principle of conservation of angular momentum of the gyroscope, can keep the concrete bucket balanced, and the device is completely driven by wind energy, which not only improves the construction efficiency, enhances the construction safety, but also has the advantage of energy conservation. To solve the above technical problems, the present invention adopts the following technical solutions to achieve: A self-stabilizing method for a bucket, wherein the bucket is equipped with a self-stabilizing device. The self-stabilizing device includes a bucket assembly, a gyro rotating assembly, and a wind-driven rotating assembly. The bucket assembly includes a slide rail swing shaft, and the gyro rotating assembly includes a gyro rotating body and a rotating body slide rail. The self-stabilizing method for the bucket includes the following steps: Step 1: Hang one end of the suspension cable on the lifting lug, and hang the other end of the suspension cable on the cable crane. Step 2: After loading the goods into the tank body, use the cable crane to lift and transport the bucket. Step 3: Under the action of wind force, the overall hanging bucket will swing back and forth along the wind direction with the wind. At the same time, the wind blades will drive the gyro rotating body to rotate along the rotating body slide rail, and the greater the wind force, the faster the rotation; Step 4: Under the action of wind force, the wind vane will automatically adjust the direction of the entire hanging bucket, so that the axis direction of the slide rail swing shaft is always perpendicular to the strong wind direction. When the entire hanging bucket swings, the gyro rotating body can always maintain a horizontal state when rotating; Step 5: According to the principle of conservation of angular momentum of the gyroscope, when the gyro rotating body rotates, it will cause the entire hanging bucket to always be subjected to a vertically downward acting force generated by the gyro rotating body. The component force of this vertically downward acting force in the radial direction of the swing of the entire hanging bucket is always opposite to the swing direction of the hanging bucket, forcing the hanging bucket to always move in the direction opposite to the swing direction, so as to achieve the effect of forcing the hanging bucket to maintain vertical balance; The flexible connection body of the wind blade at the bottom of the wind blade allows the wind blade to have a certain vertical deflection margin. When the hanging bucket swings and deflects, the wind blade on the gyro rotating body is not easy to collide and squeeze with the tank body.

[0005] Preferably, the gyro rotating assembly is arranged around the hanging bucket assembly.

[0006] Preferably, the gyro rotating assembly includes a rotating body slide rail, the rotating body slide rail is rotationally matched with the gyro rotating body, the rotating body slide rail is provided with a shaft hole, and the hanging bucket assembly is connected to the shaft hole through a slide rail swing shaft.

[0014] The present patent can achieve the following beneficial effects: The present invention adopts a rotating combination device, namely a self-stabilizing device, and utilizes the gyroscopic stabilization principle. When the hanging bucket swings under the influence of strong wind, by using the characteristic that the gravity of the rotating body always remains vertically pointing to the ground when the rotating body rotates, a force opposite to the swinging direction of the hanging bucket is always generated, forcing the bucket body to return to the vertically stable position, thereby overcoming the swing of the bucket body and ensuring the correct positioning of the hanging bucket and construction safety.

[0015] The rotation of the rotating body of the present invention is driven by a fan installed on the rotating body by natural wind power, without additional power. Moreover, the greater the wind force, the greater the rotation speed of the rotating body and the greater the restoring force, that is, the automatic operation of the system is realized and energy is saved.

The tank body 101 is connected to the shaft hole 203 through a slide rail swing shaft 108, and the wind blade support rod slip ring 305 is sleeved outside the tank body 101.

A wind direction plate 4 is fixedly connected to the top of the reinforcing hoop I 102, and the direction pointed by the wind direction plate 4 is perpendicular to the slide rail swing shaft 108; a suspension cable 5 is installed on the lifting lug 107.

[0022] The skip with a self-stabilizing device consists of five major parts: a skip assembly 1, a gyro-rotating assembly 2, a wind-driven rotating assembly 3, a wind vane 4, and a sling 5. The gyro-rotating assembly 2 includes a rotating body slide rail 201, a gyro-rotating body 202, a shaft hole 203, a safety protection cover 204, and rotating body slide rail balls 205; the wind-driven rotating assembly 3 includes wind blades 301, wind blade flexible connectors 302, wind blade connection bases 303, wind blade support rods 304, and wind blade support rod slip rings 305.

[0023] In the skip assembly 1, the tank body 101 is a container for storing concrete, with a shape of a cylinder connected to a frustum, and is welded by steel plates. To ensure the strength of the tank body, two circumferential welding tank body reinforcing hoops I 102 and reinforcing hoop II 103 are welded circumferentially on the upper and middle parts of the tank body respectively, both made by circumferential welding of steel strips. To ensure that the tank body can be stably placed upright, two columns I 105 and two columns II 106 are symmetrically welded around the tank body with channel steel. Among them, two columns I 105 are welded with a section of steel cylinder along the radial direction of the tank body at a position close to the bottom 1 / 4 as the swing axis 108 of the slide rail of the gyro-rotating assembly 2; the tank body base 104 is circular, made by cutting a steel plate, and is welded to the bottom ends of the columns I 105 and columns II 106. The lifting lug 107 is the stress-bearing component for lifting the entire device of the present invention, made of steel, welded at the upper reinforcing hoop I 102 of the tank body, and is tied to the sling 5.

[0024] To ensure that when the skip assembly 1 swings against the wind under strong wind conditions, the axis direction of the swing axis 108 of the slide rail of the skip assembly 1 is always perpendicular to the wind direction, and to meet the requirement that the gyro-rotating body 202 always maintains horizontal rotation when the skip assembly 1 swings, a wind vane 4 is welded on the upper part of the tank body reinforcing hoop I 102 of the skip assembly 1. The wind vane 4 is made of a flat steel plate, the steel plate is arranged vertically, and its direction is the radial direction of the circular inlet of the concrete skip and forms a 90° angle with the axis direction of the swing axis 108 of the slide rail.

[0025] Example 3: The preferred solution is as Figures 7 to 8 shown. The self-stabilizing method of the skip with a self-stabilizing device includes the following steps: Step 1: Hang one end of the sling 5 on the lifting lug 107, and hang the other end of the sling 5 on the cable crane. Step 2: After loading the goods into the tank body 101, use the cable crane to lift and transport the skip. Step 3: Under the action of the wind, the entire skip will swing back and forth along the wind direction with the wind, and at the same time, the wind blades 301 will drive the gyro-rotating body 202 to rotate along the rotating body slide rail 201, and the greater the wind force, the faster the rotation. Step 4: Under the action of wind force, the wind vane 4 will automatically adjust the direction of the entire suspension bin, so that the axis direction of the slide rail swing shaft 108 is always perpendicular to the strong wind direction. When the entire suspension bin swings, the gyro rotor 202 can always maintain a horizontal state when rotating; Step 5: According to the principle of conservation of angular momentum of the gyroscope, when the gyro rotor 202 rotates, the entire suspension bin will always be subjected to a vertically downward force generated by the gyro rotor 202. The component force of this vertically downward force in the radial direction of the swing of the entire suspension bin is always opposite to the swing direction of the suspension bin, forcing the suspension bin to always move in the direction opposite to the swing direction, so as to achieve the effect of forcing the suspension bin to maintain vertical balance; The flexible wind vane connector 302 at the bottom of the wind vane 301 allows the wind vane to have a certain vertical deflection margin. When the suspension bin swings and deflects, the wind vane 301 on the gyro rotor 202 is not likely to collide and squeeze with the tank body.

[0026] Working principle: When the sling 5 hoists the entire concrete suspension bin and runs at high altitude through the lifting lug 107, when encountering strong wind, the entire suspension bin will swing back and forth along the wind direction under the action of the wind. Under the action of the wind force, the five wind vanes 301 will drive the gyro rotor 202 to rotate rapidly along the rotor slide rail 201, and the greater the wind force, the faster the rotation; at the same time, under the action of the wind force, the wind vane 4 will automatically adjust the direction of the entire concrete suspension bin, so that the axis direction of the slide rail swing shaft 108 is always perpendicular to the strong wind direction. When the entire concrete suspension bin swings, the gyro rotor 202 can always maintain a horizontal state when rotating; according to the principle of conservation of angular momentum of the gyroscope, when the gyro rotor 202 rotates at a high speed, the entire suspension bin will always be subjected to a vertically downward force generated by the gyro rotor 202. The component force of this vertically downward force in the radial direction of the swing of the entire concrete suspension bin is always opposite to the swing direction of the tank body, forcing the suspension bin to always move in the direction opposite to the swing direction, so as to achieve the effect of forcing the concrete suspension bin to maintain vertical balance.
