AI Technical Summary

Technical Problem

In the prior art, when the coal pile is covered, the rope that pulls canvas is easily trapped in the coal pile, resulting in low working efficiency, high working strength and high safety risks.

Method used

A buoyancy lifting device is designed, with multiple plastic hoses placed on the rope. Each section of the hoses is equipped with conical rubber floats, and metal hooks are fixed at both ends of the rope.

Benefits of technology

By increasing the buoyancy of the rope, the float ball prevents the rope from contacting the surface of the coal pile, reducing friction, improving the efficiency of artificial canvas pulling, and reducing working strength and safety risks.

Description

Technical Field

[0001] The invention relates to a buoyancy lifting device for covering a coal pile. Background Art

[0002] Domestic coal stockpiles are divided into open-air and closed types. Due to environmental protection requirements, open-air coal yards should take measures to prevent coal dust from damaging the environment. Covering with rainproof and dustproof canvas is the most commonly used technical measure. The dust-proof plastic sheet is covered and uncovered manually. When using it, the personnel need to climb to the top of the coal pile in advance, and the canvas must be pulled to the coal pile with a rope at the top. When the canvas is pulled manually with a rope, the rope will sink into the coal pile on the outer slope of the top of the coal pile. The workers must walk to the sinking place and pull the rope out by hand, which increases the workload and low work efficiency. Employees need to climb up and down the coal mountain according to weather conditions, which is intensive and has high safety risks.

[0003] Due to the various shapes of coal piles, the irregular shapes of coal piles often change, the unevenness of the coal piles, and the uneven size of the coal pile particles, when using ropes to pull the canvas, the ropes are easily sunk into the coal piles, and the sunken ropes must be taken out manually before the canvas can be pulled again. Since the coal piles are soft, the stressed ropes will sink into the coal piles again, and this will happen repeatedly, greatly reducing the efficiency of manual canvas pulling. Summary of the invention

[0004] In order to overcome the defects of the prior art, a buoyancy lifting device for covering a coal pile is provided, which can prevent the stressed rope from sinking into the coal pile when pulling the canvas, thereby improving the efficiency of manual canvas pulling.

[0005] The above objectives are achieved through the following solutions: A buoyancy lifting device for covering a coal pile comprises: a rope, a plurality of plastic hoses are sleeved on the rope, buoyancy balls are installed at both ends of each section of the plastic hose, and hooks are fixed at both ends of the rope.

[0006] The buoyancy lifting device for covering a coal pile is characterized in that the buoyancy ball is a cone-shaped buoyancy ball, the buoyancy ball has a hole structure in the middle and is detachably sleeved on the outer periphery of a rope.

[0007] The buoyancy lifting device for covering a coal pile, wherein the hook is a metal hook.

[0008] The buoyancy lifting device for covering a coal pile, wherein the buoyancy ball is a buoyancy ball made of rubber. Beneficial Effects

[0009] 1. The present invention greatly increases the buoyancy of the rope by arranging a plastic hose with a diameter of 10 cm and a float with the same specifications on the rope. When pulling the canvas, the float can firstly increase the height of the rope so that the rope does not contact the surface of the coal pile. Secondly, the float adopts a cone shape with thin ends and a thick middle, so the float will not sink into the coal pile, and the friction resistance is small when the float contacts the surface of the coal pile, so that the traction rope floats on the surface of the coal pile and does not sink into the coal pile, and the friction between the rope and the coal pile is reduced, thereby improving the efficiency of manually pulling the canvas. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a front view of the present invention; Figure 2 is a side view of the present invention; In the picture: 1. Hook; 2. Rope; 3. Buoyancy ball; 4. Plastic hose. DETAILED DESCRIPTION

[0011] A buoyancy lifting device for covering a coal pile comprises: a rope 2, a plurality of plastic hoses 4 are sleeved on the rope, buoyancy balls 3 are installed at both ends of each section of the plastic hose, and hooks 1 are fixed at both ends of the rope.

[0012] The buoyancy lifting device for covering a coal pile is described. The float is a conical float. In order to reduce the friction with the surface of the coal pile, the float adopts a conical shape to reduce the contact area with the surface of the coal pile. The buoyancy ball has a hole structure in the middle and can be detachably mounted on the outer periphery of the rope.

[0013] The buoyancy lifting device for covering a coal pile, wherein the hook is a metal hook.

[0014] The buoyancy lifting device for covering a coal pile, wherein the buoyancy ball is made of rubber, and the buoyancy ball is made of rubber to increase strength and reduce weight; In order to improve the buoyancy, a plastic hose is installed on the rope. The length of the plastic hose is 50 cm and the diameter of the plastic hose is 10 cm. Buoyancy balls are installed at both ends of each section of the plastic hose, that is, the buoyancy balls are installed on the rope at a certain interval (50 cm), and metal hooks are set at both ends of the rope for connecting the canvas. Since the present invention is provided with a plastic hose with a diameter of 10 cm and a buoyancy ball of the same specification on the rope, the buoyancy of the rope is greatly increased. When the canvas is pulled, the buoyancy ball will firstly increase the height of the rope so that the rope does not contact the surface of the coal pile; secondly, the buoyancy ball adopts a cone-like shape, which is thin at both ends and thick in the middle, so the buoyancy ball will not sink into the coal pile, and the friction resistance when the buoyancy ball contacts the surface of the coal pile is small, so that the traction rope floats on the surface of the coal pile and does not sink into the coal pile, and the friction between the rope and the coal pile is reduced, thereby improving the efficiency of manually pulling the canvas.
