Sliding plate device for covering coal pile

Abstract

The invention discloses a sliding plate device for covering a coal pile. At present, mechanical canvas covering devices are applied to partial power plants, canvas is connected through ropes of winches, the winches are started to cover coal piles with the canvas through the ropes, and the canvas cannot climb over the tops of the coal piles due to the fact that the canvas bears horizontal tension when reaching the outer sides of the tops of the coal piles and sinks into the tops of the coal piles to generate resistance. In the prior art, workers need to pull out canvas at a collapse position through manual intervention in a coal mountain, so that workload is increased, working efficiency is low, working intensity is high, and safety risk is high. The device comprises a sliding plate (1), a cambered surface A (5) and a cambered surface B (6) are arranged at the left end and the right end of the sliding plate respectively, a reinforcing plate A (3) and a reinforcing plate B (4) are fixedly connected to the bottom face of the sliding plate, a metal pipe (2) is fixedly connected to the middle of the sliding plate, the front end and the rear end of the metal pipe penetrate through the reinforcing plates and are fixedly connected, and a through hole (7) is formed in the middle of the metal pipe. The device is used for preventing flying coal dust from damaging the environment and covering the coal pile with canvas.

Description

Technical Field

[0001] The invention relates to a slide plate device for covering a coal pile. Technical Background

[0002] Due to environmental protection requirements, domestic 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 most commonly used technical measure at present is to cover the coal pile with rainproof and dustproof canvas. Manual intervention is required during use. Use a rope from the top of the coal mountain to pull the canvas to the bottom to complete the coverage.

[0003] At present, some power plants use mechanical canvas covering devices, which connect rainproof and dustproof canvas with ropes on the winch, and use the ropes to cover the coal pile with the canvas when the winch is opened. When the canvas reaches the outside of the top of the coal pile, it will be subjected to horizontal tension and will sink into the top of the coal pile to generate resistance, making it impossible for the canvas to climb over the top of the coal pile. At this time, workers are required to climb up and down the coal pile to manually intervene in the sunken area and pull out the canvas, which increases the workload, reduces work efficiency, increases work intensity, and poses high safety risks.

[0004] In summary, a slide plate device for covering a coal pile is needed to solve the above problems. Summary of the invention

[0005] The purpose of the invention is to solve the problem that the rainproof and dustproof canvas of an open-air coal yard sinks into the coal pile during the covering process, and provides a slide plate device for covering the coal pile.

[0006] To solve the above-mentioned shortcomings, the present invention adopts the following technical solutions: A slide plate device for covering a coal pile comprises a slide plate, wherein a cambered surface A and a cambered surface B are respectively arranged at the left and right ends of the slide plate, the bottom surface of the slide plate is fixedly connected to a reinforcing plate A and a reinforcing plate B, and the middle position is fixedly connected to a metal pipe, the front and rear ends of the metal pipe pass through the reinforcing plate and are fixedly connected, and a through hole is arranged in the middle position of the metal pipe. Beneficial Effects

[0007] 1. The installation of the slide device of the present invention avoids the situation that the canvas is easily pressed by the coal due to the resistance generated when the covering canvas reaches the top of the coal pile, reduces the labor intensity of the workers, improves the labor efficiency, avoids the danger caused by the workers climbing up and down the coal pile in extreme weather conditions, and ensures the safety of the workers.

[0008] 2. The curved surfaces at the left and right ends of the skateboard device of the present invention face upward, and reinforcing plates are added on both sides of the skateboard to enhance the strength of the skateboard, improve the stability of the device, and extend the service life of the device.

[0009] 3. The present invention has a simple structure and is easy to repair and install, which improves the convenience for subsequent maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In the figure: 1. skateboard; 2. metal tube; 3. reinforcing plate A; 4. reinforcing plate B; 5. arc surface A; 6. arc surface B; 7. through hole. DETAILED DESCRIPTION

[0013] Reference Figure 1-2 The present invention comprises a skateboard 1, wherein the left and right ends of the skateboard are provided with arc surfaces A5 and arc surfaces B6 respectively, and the bottom surface of the skateboard is fixedly connected with reinforcing plates A3 and B4, and the reinforcing plates increase the structural strength of the skateboard and can reduce the deformation of the skateboard caused by external forces during use. A metal pipe 2 is fixedly connected to the middle position of the bottom surface of the skateboard, and the front and rear ends of the metal pipe pass through the reinforcing plates and are fixedly connected, and a through hole 7 is provided in the middle position of the metal pipe, and the through hole is used to fix the rope.

[0014] Working principle: This device requires a set to be used in conjunction (a set consists of two). Before using the device, firmly connect one end of the rope on the winch to the canvas covering the coal pile, and then insert the other end of the rope into the metal pipe and then into the round hole on the metal pipe. Tie a knot on the rope and fix it to the slide device. After preparation, turn on the winch, and the winch will be used as a power to tighten the rope. The rope will drag the slide device to drive the canvas, completing the work of covering the coal pile with the canvas.
