Abstract
The invention relates to the field of belt conveying of coal mines, in particular to a short-section belt conveyer. The short-section belt conveyer comprises a conveying belt composed of an upper-layer belt body and a lower-layer belt body, and further comprises a headstock, a tensioning tailstock, an electric roller and a belt carrying roller, wherein the headstock and the tensioning tailstock are supported in a roadway; the electric roller is installed at the head of the headstock and serves as a driving mechanism; the belt carrying roller is installed on the lower portion of the headstock and used for changing the direction. The short-section belt conveyer effectively relieves the labor intensity of manual tunneling of a tunneling head due to the simple structure, the weight and size which can facilitate movement and small investment, reduces the number of workers, improves work efficiency, is large in conveying quantity, has only a few failures, is low in later maintenance cost, is high in safety coefficient, and meets the standard requirements. The use length of the belt is shortened from more than 100 m to 30-70 m.
Description
Technical field
The present invention relates to coal mine leather belt transportation art, specifically a kind of pipe nipple band conveyor.
Background technology
Panel, down-hole adopts double-vane exploitation, and wherein a wing gateway belt directly overlaps panel belt, and another wing gateway belt adopts 40 slat conveyers and panel belt to overlap.40 slat conveyers are primarily of parts compositions such as driving section, pushing beam, transitional slot, intermediate channel, scraper chain, tail, left baffle, and driving section is primarily of parts compositions such as electrical motor, retarder, sprocket wheel, headstock, hyoplastron, blind axle, chain tensioner sheets.Because 40 slat conveyer no-load power consumptions are comparatively large, be about 30% of gross horsepower, consume steel many, cost is large, easily falls chain, jumps chain accident.And overlap bad due to 40 slat conveyers and panel belt, slip head place and beat and press thick stick in an opposite direction, operation is various, and safety factor is low, does not meet standardisation requirements.Waste time and energy in installation and handling process, intermediate channel is yielding when being subject to larger impact, recover more difficult, slat conveyer corrosion stability wears no resistance, and the friction coefficient of material and intermediate channel is large, and the power major part of slat conveyer consumes on the friction force of material and intermediate channel, cause energy consumption excessive, investment increases, daily attention difficulty, Frequent Troubles.
Summary of the invention
The problems that the present invention exists to solve existing 40 slat conveyers, provide a kind of pipe nipple band conveyor.
The present invention is achieved by the following technical solutions: pipe nipple band conveyor, comprise the belt conveyor be made up of upper strata belt and lower floor's belt, also comprise and be supported in headstock in roadway and tensioning tailstock, be installed on the motorized pulleys of headstock head as driver train, be installed on headstock bottom for what alter course and entrust cylinder;
Described tensioning tailstock comprises and is supported in ground base, two tensioning leading screws, is supported in two tensioning frames of the left and right sides above base along belt conveyor transporting direction respectively; Each tensioning frame is all be made up of the channel-section steel that two openings are relative, the base of each channel-section steel is welded on base, strip crevice is left between the top margin of two channel-section steels that opening is relative, one in front and one in back two square nuts have been placed respectively in the two channel-section steel grooves that opening is relative, be connected with steel pipe socket with one heart with screw between two square nuts, each square nut top is all stretched out strip crevice and is formed a brace table, be bolted supporting seat between two brace tables, between two supporting seats on two tensioning frames, be supported with aircraft tail cylinder; The screw thread of tandem two square nuts in the same way, after the threaded portion of described tensioning leading screw and square nut screw thread fit below through steel pipe socket, then with square nut screw thread fit above, be positioned in the tensioning pole wire lever portion outside two channel-section steels and be circumferentially equipped with snap ring, this snap ring coordinates with tensioning frame end is spacing, be positioned at tensioning pole wire lever portion outside snap ring vertically and left and right directions have upper and lower knock hole and left and right knock hole.
The present invention is mainly used in the transport systems of coal mine down-hole tunnel driving face, also can be used for mining face under mine Da Qie lane, tunnelling transport time tail end connect with development machine.During concrete use, insert bull stick in upper and lower knock hole or left and right knock hole, rotate tensioning leading screw, drive square nut and steel pipe socket to seesaw by tensioning leading screw, and then drive aircraft tail cylinder crank motion, play conveying belt tensioning effect.
Pipe nipple band conveyor of the present invention with simple structure, the weight and volume just moved, little investment, effectively reduce the labour intensity that heading end manually tunnels, reduce recruitment number, raise labour efficiency, operational throughput is large, fault is few, later maintenance expense is low, and safety factor is high, reaches standardisation requirements, shorten the use length of belt, shortened to the belt of present 30 to 70 meters of delivered length by the belts of original more than at least 100 meters.
