Description
Technical field
Belt of belt conveyor sideslip automatic deviation rectifying device, belongs to band conveyor technical field of auxiliary equipment.
Background technology
Band conveyor is in course of conveying, and the operation fault of sideslip often appears in belt, not only easily damages belt, but also can cause other potential safety hazard when belt deviation fault occurs, and endangers very large.Existing block roller can prevent belt deviation, but comparatively large to belt wearing and tearing, cause belt crimping even to cause tearing tape accident when belt deviation is serious, manual regulation can not reach instant correction again, belt returns timing and can not reach again and immediately cancel correction, and makes belt be partial to opposite side.Existing deviation correcting technology can only solve belt deviation among a small circle, and adopt the light-duty belt transporter of three cylinders to be normally placed in tunnel or the poor location of surface condition, belt holder displacement, belt loading are uneven, belt distortion and left when binding the belt caused such as irregular time right sideslip, must development be a kind of can immediately effectively rectify a deviation and to the less device of belt wearing and tearing, be beneficial to increase band conveyor transport efficiency and stability, prolongation belt service life.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can the device of automatic deviation correction when belt deviation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: belt of belt conveyor sideslip automatic deviation rectifying device, comprise arc-shaped rack, double-layer gear, block roller gear, end friction lining and casing, friction lining of the described end is arranged on the bottom of block roller, described block roller gear is connected to the below of end friction lining by block roller axle, the same plane of described block roller gear is provided with the double-layer gear with block roller gears meshing, described double-layer gear is made up of the gear of two different size diameters, and the gear that diameter is little engages with the arc-shaped rack being arranged on described box house, the gear that diameter is large and described block roller gears meshing, described arc-shaped rack two ends are connected to belt holder side through casing, described block roller gear simultaneously, double-layer gear is all positioned at box house, described casing outside is connected with idler machining by bearing pin, be connected with block roller axle by bearing.
At the top of described block roller, top friction lining is also set, above the friction lining of described top, the top of block roller axle is also provided with setting nut and spring, described setting nut is connected with block roller axle screw top, described spring housing is outside at block roller axle, and the bottom of spring is connected with top friction lining elasticity, top is connected with setting nut elasticity.
The connection hole of described box house and arc-shaped rack is also provided with dust-proof guard, and described dust-proof guard one end is connected by coil tension spring with cabinet wall, the other end above connecting bore, the spacing slideway of below moves around.
Described top friction lining and block roller top are that feather key is connected, and are flat key static connection bottom friction lining of the described end and block roller.
Compared to the prior art the utility model has following beneficial effect.
One, can block roller be touched when belt deviation and drive block roller to rotate, and then drive is pushed up friction lining, end Friction disk, block roller axle, is rotated together with block roller gear, so block roller gear transmission double-layer gear, double-layer gear is again along arc-shaped rack gear transmission, along with the movement of small diameter gear on arc-shaped rack of double-layer gear, also there is equidirectional skew in idler machining thereupon, and idler machining drives again belt to offset together, thus avoid belt and continue sideslip at idler machining, reach correction object.Then when belt returns timing belt and block roller disengages, the small diameter gear of double-layer gear gets back to the middle part (namely arc top portion) of arc-shaped rack gradually under the pulling force effect of three holder rod groups, at this moment idler machining, belt is also along with getting back to initialization position, thus achieve the operation angle single-ended hanging point skew of idler machining being changed to idler machining, reach and the automatic deviation correction of belt is operated, the utility model structure is simple, but actv. solves the unrestrained and tearing tape accident of goods that belt deviation causes, existing band conveyor basis is changed less, extensively can use on existing belt transporter, only change the hook (rake) of three holder rod group sides, not only improvement cost is low, load and unload simultaneously, safeguard easily, service life is also long, and have same correction effect when belt rotating, the present situation can not rectified a deviation when changing belt reversing.Can widespread use in the band conveyor conveying of reality.
Two, setting nut and spring are set at block roller top, by precession, screw out the adjustment of setting nut realization to spring pressure size, the pressure size suffered by end friction lining bottom the top friction lining at such block roller top, block roller changes thereupon, also the adjustment of pressure sensitivity when block roller is touched block roller to belt and drives block roller to rotate just is achieved, easy to adjust, sensitivity is also high.When arc-shaped rack reaches the correction limit, at the bottom of block roller and block roller top, Friction disk starts to skid, and now block roller has been held concurrently the effect of common block roller, reaches doubling deviation, improves centering capacity.
Three, dust-proof guard is set in the connection hole of box house and arc-shaped rack, dust-proof guard can be moved around along spacing slideway by coil tension spring, when casing moves along arc-shaped rack, coil tension spring promotes or pulls dust-proof guard to do to move in the same way, this makes it possible to remain that connecting bore only has the sponson of arc-shaped rack to have opening, other opening portions are then blocked by dust-proof guard, thus prevent the foreign matter of casing outside from entering casing from connecting bore, and then affect the transmission work of gear.
