Vertical bucket elevator installation and construction process

1 bucket elevator bucket on the top of the upper mounting consists of: upper part of the bucket elevator drive unit (motor, reducer and base), couplings, wheels and frame

composition on tape. Bucket elevator installation process equipment unpacking upper acceptance, dumps the device from the device using a forklift truck

Equipment or truck to the ground near the building in which, if the device location is a layer, then the direct use of a forklift or truck to equipment base side. If the device

is based on a higher position, then use crane lifting, crane model selection should refer to the location of the height of the equipment, lifting position back in.

Turn radius and weight of the equipment. If the equipment is overweight, high position, then prepared a separate lifting program. After re-inspection equipment foundation, hand

truck or hoist with two roll bar will add bucket elevator drive unit (motor,powered roller conveyor reducer and base), couplings, flat on the belt wheel and bracket

Move equipment base side, and then use the chain to enhance the place. Drive unit and the tape wheel alignment bracket in place: on the basis of the cross according to the

centerline respectively on tape drives and wheel bracket for alignment, the drive to find Punctuality is: drive on the base surface of the motor and

Reducer coupling between (or the motor output shaft) and the reducer output shaft; wheel bracket on the tape to find Punctuality is: on the upper surface of the base tape wheel

bracket and bracket two belt wheel bearing face. Find positive ways to use box-type levels measured, using oblique horn adjustment, the two groups

L should be less than the spacing between the horn 500mm, and the horn placement should be symmetrical. Horn specifications and dimensions shall meet GB50231-98 "machinery and

equipment for construction and acceptance of universal norms" Appendix V requirements. Drive unit and the belt wheel bracket grouting: after passing the time alignment with a

fine stoneskate roller conveyor

Once concrete grout, to be concrete strength of 75%, it can be secondary grouting. Note the following: (a) bolt hole size to meet the requirements; (2) bolt hole should be clean

and free of debris; (3) anchor bolts should be vertical, anchor bolts protruding screw nut 2-3

Distance. 2 bucket elevator bucket elevator lower lower mounting consists of: bucket wheel machine tape from the next lower and lower base composition. Intermediate guide wheels

bucket elevator installation according to the middle of the installation guide wheel installation diagram, measured by the middle of hanging wire guide wheel center axis

deviation. Install the middle

Guide wheels should note the following: All the central axis of the intermediate guide wheels should be parallel to each other and with the bucket elevator up and down the

central axis of the tire in the same vertical plane, tolerance of ± 2mm. All intermediate guide wheels the outer contour line should be in the same vertical plane, tolerance of

± 2mm

. 3 bucket elevator enclosure mounting structures: bucket elevator casing is composed of many segments rectangular flange bolts, gasket from the middle. Installation procedures

bucket elevator belt wheel up and down after installation tape according to the specific characteristics of bucket elevator, bucket elevator sub-assembly housing. In order to

have

The installation tape and hopper, bucket elevator generally reserved for close to a section of the lower belt wheel bucket elevator casing, bucket elevator Central section of

the upper housing and the bucket elevator discharge port cover. Measured with a hanging wire bucket elevator casing nonstraightness. Mention machine shell intermediate support

device installation: Because

Bucket elevator casing longer and have a certain weight, the installation must have some intermediate support means supporting bucket elevator casing. Intermediate support

device according to installation diagram and installation requirements for installation. Bucket elevator enclosure Note: (1) bucket elevator casing connections between segments

at the gasket should be

Sealed and can not force the connection. (2) bucket machine housing should not straightness ≤ H/1000, and ≤ 6mm. 4 tape and mounting tape hopper connection: connection methods

tape and plastic bolted France legally, their connections shall comply with the following requirements: (1) both ends of the rubber cloth tape should

Corresponding ladder cord layers cut into the shape of the joint length should be 1-2 times the width; (2) the material with adhesive tape material should have the same

flexibility; (3) joints should be firm, increasing the thickness of the joints , should not exceed 5% of the tape thickness; (4) Adhesive tape sulfur

Temperature and curing time and room temperature bonding shall comply with technical documents and adhesive equipment requirements; (5) tape bolted or glued joints should

overlap along the tape running direction; (6) tape needed pretensioners, pre- Rally Rally for the job should be 1.5-2 times the duration of the pre-pull

To 24 hours. (7) hopper installation: bucket elevator manufacturers in accordance with installation drawings and specification requirements for installation hoppers. Install

hopper to note the following: in strict accordance with bucket elevator manufacturers installation drawings and specification requirements for installation, not free to change

the hopper

Location and number; joints hopper installation: lap length should span three hopper, which is connected with the tape ends of the bolt axis distance of not less than 50mm.
