Bucket Elevator factory is divided into several parts , so refer to the following in accordance with site-specific installation order of the various components shipped to the installation site in advance the appropriate location , depending on the installation master plan , refer to the following requirements for installation :
1 according to the drawings, based on the anchor bolt holes checked .
2 would be fixed on the basis of the lower section and the leveling datum ( the flange ) . On the flange surface and the horizontal parallelism tolerance is 1/1000mm. Adjust the horn must be close to the anchor bolts.
3 chassis and connection box installed, peripheral flange must be neat , there should be significant dislocation. The connection between the housing flange pad into 3mm thick asbestos rope , asbestos rope can be coated with some butter , asbestos rope positioned to facilitate and increase the sealing effect. Mat asbestos rope , first put on the chassis flanges bolts, then bolt the outer perimeter of the flange connection .
4 chassis mounted to a certain height ( according to the technical design ) . Install outdoor ( internal ) fixing bracket, to be securely fixed to the nearest building. Mounting bracket generally an interval of 8 ~ 10m , mounting bracket allow limitations hoist in the vertical direction of the free expansion .
5 If you have non-standard chassis, generally installed in the upper section of the festival under the first position, if you have special requirements, can be installed in a different location.
6 side mounted chassis, while measuring the vertical cabinet .
7 The upper section of the installation, to calibrate the spindle centerline , so that the lower level and with the centerline of the shaft parallel alignment. Upper shaft parallel with the horizontal centerline tolerance is 0.3/1000mm, down axis perpendicular plane with error less than 4mm, the upper and lower rollers face the same vertical plane error is less than 5mm.
8 drives in the elevator factory has been connected with the upper section of the drive spindle is good, and install location, taking into account the vibration during transportation equipment factory , as well as lifting may occur during collisions. Therefore , the upper section

Bucket elevator works
Bucket Elevator for conveying powder, granular and small block of non-abrasive and small abrasive materials. TH is a type of ring chain bucket elevator use of hybrid or gravity discharge, digging loader. Tractor parts with high quality steel ring chain. Central case of single-, dual-channel two forms of machine hammer box Constant automatic tensioning. Sprocket rims interchangeable modular structure. Long life and easy replacement rim. The lower the gravity automatic tensioning device, to maintain a constant tension, to prevent slippage or from chain, while the hopper stuck encountered phenomenon caused by accidental factors have a certain tolerance so that resistance, can effectively protect the lower shaft member. The bucket elevator for conveying bulk density of less than 1.5t/m3 easy to dig a powder, granular, small block bottom abrasive materials. Such as coal, cement, gravel, sand, fertilizer, food and so on. TH-type bucket elevator for a variety of vertical transport of bulk materials. Suitable for conveying powder, granular, small block materials, classic statement material temperature below 250 ℃.
Bucket elevator conveyor working principle is: the material from the hopper to scoop up the following storage medium, with conveyor belts or chains upgraded to the top, flip down after bypassing the top wheel, bucket elevator material is poured into the receiving groove inside. Belt bucket elevator drive transmission belt generally use rubber band attached to the lower or above the upper and lower drive roller and the idler pulley. Chain bucket elevator drive with two generally parallel transmission chain, or following a pair of drive sprocket, under or on top of a pair of headed sprocket. Bucket elevators are generally equipped with chassis, in order to prevent the bucket elevator in dust.

Bucket elevator tensioning device redesign
Bucket Elevator tensioning device redesign :
Since bucket elevator has a small footprint , full sealed transmission, reduce environmental pollution, is commonly used in conveying bulk material handling equipment .
Bucket elevators work in order to stabilize the normal operation of the traction needed for tensioning member tensioning force is called the tension generated ; keep running tension is called the minimum initial tension , the tension is too early to accelerate parts wear in , initial tension is too small , traction wheel slip or towing parts and pieces of deflection , is not working properly . Tractor parts with tape, ring chain , plate chain several structures , performance is not the same, so the selection of the tensioning method is also different , the current methods commonly used tensioning screw tensioning tensioning lever hammer , hammer tensioning , composite tension and so on.
Screw mounted on the lower part of the chassis , nut U-shaped groove in the support plate , when the rotary screw , they can move the support plate , the lower bearing is fixed on the support plate, thereby enabling lower tension roller to pull pieces . This method is suitable for tensioning the tape for traction member using bucket elevators , the tape a certain degree of flexibility , when given elongation , the adjustable tensioning screw , in order to ensure stability of the work tape .
The hammer lever tensioning force acts on the support plate , fixed to a lower bearing support plate , so that the lower part of the pulling element driven sprocket taut. This is an automatic tensioning device , hammer follower lever has a certain resistance, traction member to stay in the skin with a certain tension, so that the stable operation of the drive in the chain hoist is usually applied to avoid slipping off the chain and the application effect.
Tensioning hammer , hammer gravity via the bracket directly to the lower bearing housing , the pulling of the lower driven sprocket member taut, and the hammer lever tensioning methods, to achieve the same tension , more weight . So commonly used in weight pulling pieces larger plate chain hoist in position space is small, automatic tensioning method .
Composite tension , combined with the spring hammer , pressure in the lower bearing seat, so that the lower part of the traction drive wheel parts taut, composite tension in between the hammer and the lower bearing housing plus a set of spring , so too rear axle when wearing a certain buffer , suitable for use in traction hoist pieces larger self , the use of attention on both sides of equal weight hammer block , avoid heavy.
