Abstract
The invention relates to a tail wheel for preventing the chain dropping of the tail of a scraper conveyor and the scraper conveyor, belonging to the technical field of scraper conveyors.
Description
Technical Field
The invention belongs to the technical field of scraper conveyors, and particularly relates to a tail wheel for preventing a tail of a scraper conveyor from falling off a chain and the scraper conveyor.
Background
The scraper conveyor is the most common coal material transportation equipment in coal mine coal preparation plants, has the characteristics of convenient coal distribution and blending, large transportation capacity, long service life, low cost, cleanness, sanitation and the like, and is widely applied in the coal preparation industry. Along with the increase of the coal mine yield, higher requirements are put forward on the reliability, the stability and the accident rate of equipment. In the operation process of the scraper conveyor, the problems of loose scraper chain, large transported material, incorrect supplied material, processing quality and precision often occur, so that the scraper chains on two sides are not abraded uniformly and are not uniform in length, and further the machine head and the machine tail are not aligned. When large coal blocks or gangue are clamped into the tail wheel, the tail chain of the scraper conveyor is easy to fall off, if the vehicle is not stopped in time, accidents are likely to be expanded, if the scraper chain, the hinge and other major accidents are broken, and the safety production and the economic benefit are affected.
Disclosure of Invention
In order to solve the above problems, a tail pulley and a scraper conveyor for preventing the tail of the scraper conveyor from falling off the chain are proposed.
In order to achieve the purpose, the invention provides the following technical scheme:
the utility model provides a prevent tailwheel of scraper conveyor tail chain that falls, its sets firmly in the both ends of tailwheel axle, the interval is equipped with two chain grooves on the tailwheel, be connected with the section of thick bamboo skin between two chain grooves, and leave the clearance between section of thick bamboo skin surface and the scraper blade bottom, one side that the section of thick bamboo skin was kept away from in the chain groove is equipped with the fender dish.
Furthermore, the cylinder leather sleeve is arranged on the periphery of the tail wheel shaft and is cylindrical.
Further, the bobbin skin is connected with the tail pulley through a welding mode.
Furthermore, the cylinder skin is made of a steel plate, and the thickness of the cylinder skin is 6-10 mm.
Further, the cylinder skin is made of a Q235 steel plate, and the thickness of the cylinder skin is 6 mm.
Further, the height of the blocking disc is 40-45 mm.
Further, the gap is 5-8 mm.
In addition, the invention also provides a scraper conveyor which comprises the tail wheel for preventing the tail of the scraper conveyor from falling off the chain.
Furthermore, the tail wheel shaft is connected with a rack of the scraper conveyor through a bearing and a bearing seat.
The invention has the beneficial effects that:
the scraper chain is firmly limited in the chain groove by means of the barrel skin and the baffle disc, the normal operation of the scraper is guaranteed, the problem that the scraper chain falls off due to the fact that a large coal, gangue and ironware are clamped into the tail wheel is thoroughly solved, major accidents such as breaking of the scraper chain and the hinge are avoided, the structure is simple, the investment cost is low, and the safety benefit and the economic benefit are high.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the drawings: 1-tail wheel, 2-tail wheel shaft, 3-chain groove, 4-cylinder skin, 5-baffle disc, 6-bearing seat and 7-bearing.
Detailed Description
In order to make the technical solutions of the present invention better understood, the following description of the technical solutions of the present invention with reference to the accompanying drawings of the present invention is made clearly and completely, and other similar embodiments obtained by a person of ordinary skill in the art without any creative effort based on the embodiments in the present application shall fall within the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The first embodiment is as follows:
as shown in figure 1, the tail wheel for preventing the chain from falling off from the tail of the scraper conveyor is fixedly arranged at two ends of a tail wheel shaft 2, and two chain grooves 3 are arranged on the tail wheel 1 at intervals to accommodate scraper chains.
A cylinder skin 4 is connected between the two chain grooves 3, and the cylinder skin 4 is sleeved on the periphery of the tail wheel shaft 2 and is cylindrical. A gap is reserved between the surface of the cylinder skin 4 and the bottom of the scraper blade, and the gap is preferably 5-8 mm. In order to improve the stability, the drum skin 4 is connected with the tail wheel 1 through a welding mode. Meanwhile, the bobbin skin 4 is made of a steel plate and has a thickness of 6-10 mm, and in the embodiment, the bobbin skin 4 is made of a Q235 steel plate and has a thickness of 6 mm.
The side of the chain groove 3 far away from the drum skin 4 is provided with a baffle disc 5, the height of the baffle disc 5 is 40-45 mm, preferably 40mm, that is, the baffle disc 5 is slightly higher than the scraper chain.
A scraper conveyor comprises the tail wheel for preventing the tail of the scraper conveyor from falling off a chain. The tail wheel shaft 2 is rotatably connected with a frame of the scraper conveyor through a bearing 7 and a bearing seat 6. An end cover is arranged at the position of the bearing 7, and a framework oil seal is arranged on the end cover. In the scraper blade operation process, when the scraper chain goes out of the groove under the exogenic action, under the limiting action of section of thick bamboo skin 4 and fender dish 5, the scraper chain can get into chain groove 3 automatically, guarantees scraper blade normal operating, has thoroughly solved and has led to the fact the scraper chain to fall the chain problem because of bold coal, waste rock, ironware card tail pulley, simple structure, and the input cost is low, and security benefit and economic benefits are high.
The present invention has been described in detail, and it should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
