Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of basic engineering, and in particular relates to a metal sliding device for improving buoyancy. Background Art
[0002] As people's awareness of environmental protection continues to increase, the national and local governments have increasingly stringent environmental protection requirements for industrial enterprises. For open-air coal yards, effective measures must be taken to control coal dust to reduce pollution to the atmospheric environment. Relevant environmental protection laws and standards are constantly being improved, and clear requirements have been put forward for the dust emission limits of coal yards, prompting enterprises to actively seek effective dust prevention technologies.
[0003] The mechanical canvas covering device is usually composed of a drive system, a guide rail, a canvas and a control system. The drive system unfolds the canvas to cover or uncover the open-air coal pile. The canvas has good sealing properties, can effectively block the flying of coal dust, reduce pollution to the environment, is easy to operate, saves labor costs, and runs smoothly during the covering and uncovering process without causing damage to the coal pile and surrounding facilities. However, the existing problem is that when the canvas reaches the outside of the top of the coal pile, it is subjected to a horizontal pulling force, causing the canvas to sink into the coal surface at the top of the coal pile, thereby generating great resistance, causing the canvas to be unable to cross the top of the coal pile, and the canvas is sunk into the coal pile, and the covering cannot be completed smoothly. When the canvas is sunk into the coal pile, the worker must go to the sunken place and pull the canvas out by hand, which increases the workload, and it is very inconvenient to climb up the coal pile, with high safety risks, which greatly reduces work efficiency.
[0004] The purpose of the present invention is to solve the problem of canvas getting stuck in the coal pile. The canvas is fixed on the slide, and the two ends of the front part of the slide are raised by 20-30 degrees. The force on the canvas is transferred to the slide. When it is at the top of the coal pile, although the slide is also subjected to upward and horizontal pulling forces, the horizontal pulling force cannot pull the slide into the coal pile because the slide is always at an upward angle. Under the action of the upward force, the slide will continue to move upward, thereby driving the canvas fixed on the slide to move upward and turn over the coal pile to achieve full coverage of the coal pile. Although the upward and horizontal pulling forces on the slide are very large, the overall structural strength of the slide is greatly enhanced because the slide is installed with two parallel reinforcement plates and a reinforcement plate at the tail, ensuring that the slide will not be deformed or damaged under large pulling forces.
[0005] Therefore, the existing mechanical canvas covering device used in open-pit coal plants is difficult to meet the needs of actual use, so there is an urgent need for improved technology on the market to solve the above problems. Summary of the invention
[0006] In view of the defects and shortcomings in the technology, the utility model provides a metal sliding device for improving buoyancy, which aims to prevent the canvas from sinking into the slide plate of the coal pile and change the force direction of the canvas.
[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: A metal sliding device for improving buoyancy, comprising a flat slide plate (4), the front end of the flat slide plate (4) being fixedly connected to two lifting plates (2), a groove (1) being formed between the two lifting plates (2), a through hole (3) being provided in the middle of the front end of the flat slide plate (4), and three reinforcing metal plates (5) being fixedly connected to the bottom of the flat slide plate (4).
[0008] The metal sliding device for improving buoyancy, wherein the upward angle of the upward plate (2) is 20° to 30°, a groove (1) is formed between the two upward plates (2), and the width of the groove (1) is 10 to 15 cm.
[0009] The metal sliding device for improving buoyancy, wherein the two reinforcing metal plates (5) on both sides of the bottom of the planar slide plate (4) are arranged in parallel, and a reinforcing metal plate (5) at the tail of the planar slide plate (4) is fixedly connected perpendicularly to the two reinforcing metal plates (5) on both sides of the bottom. Beneficial Effects
[0010] 1. The present invention fixes the canvas on the device, and the two ends of the front part of the slide are raised 20-30 degrees. The force on the canvas is transferred to the slide. When it is on the top of the coal pile, although the slide is also subjected to upward and horizontal pulling forces, the slide is always angled upward, and the horizontal pulling force prevents the flat slide from getting stuck in the coal pile, making it impossible to cover the coal pile normally. Under the action of the upward force, the slide will continue to move upward, thereby driving the canvas fixed on the slide to move upward, thereby turning over the coal pile to achieve full coverage of the coal pile.
[0011] 2. The present invention greatly enhances the overall structural strength of the skateboard by installing two parallel reinforcement plates at the bottom of the skateboard and a reinforcement plate at the tail, ensuring that the skateboard will not deform or break under high tension. 3. The present invention has a simple structure and low manufacturing cost, and can greatly improve work efficiency, prevent the coal pile from being stuck during covering, and reduce the risk of workers at work.
