What Are The Installation Requirements And Precautions For Apron Feeder
Apron feeder is an important heavy-duty feeding equipment, which can be widely used in coal, mining, sand aggregate, building materials and other industries. Because of its large load, large processing capacity, wear-resistant, low maintenance cost, and life-long maintenance free chain, apron feeder has been widely concerned and used. Here’s how to install and pay attention to apron feeder:
Installation of apron feeder
A. Determine the installation center of the feeder and the installation position of the head and tail, and mark it accordingly on the top and bottom plate.
B. Lift the feeder to the corresponding position. During the lifting process, attention should be paid to the assembly size of each part of the fuselage to keep the machine straight
Degree; tighten bolts when installing bolt fasteners. The frame is generally installed on the foundation under the storage bin or funnel, by embedding
The bolt is connected with the frame. If the bolt is not connected, the foundation should be equipped with a embedded steel plate, and the frame should be welded in the embedded by welding method
On the steel plate, if the height needs to be adjusted, the gasket can be used, but the gasket must be welded on the embedded steel plate to make the three become
One.
C. Hang the sprocket shaft device and tension device on the frame, install the connecting bolts, adjust the bearing seat to make the sprocket shaft and the frame
The perpendicularity of the center line is not greater than 1/1000 of its bearing span, and the levelness is not greater than 1/1000. When installing the tension device, pull it tight
The parallelism between the shaft line of the device and the shaft line of the sprocket shall not be greater than 0.5/1000 of the bearing span, taking the two axes as the basis
The difference between the angles should not be greater than 1/1000. After the adjustment meets the requirements, the sprocket device and the tension device are fixed on the frame with bolts.
When installing the support wheel, the longitudinal and transverse straightness of the axis line of each support wheel is not greater than 1, and the adjustment pad is allowed during installation.
D. Set the motor reducer together on the spindle, lock it through the locking disc, and the bolts of the locking disc should be crossed
Tighten, use force to lift the hand evenly, each bolt tightening torque of 470n.m.
E, adjust the screw of the tension device, so that the apron feeder bearing seat reaches the minimum position of the tension device before hoisting the chain plate device
The bottom of the frame (front and back can be), with steel plate or channel steel cushion, cushion the height of the same as the sprocket, and then used at the other end
The crane lifts, and the wire rope is hung at the end of the chain plate to slide the chain plate from one end to the other. When moved to a certain distance then will another
The end chain plate is connected, and the track chain coupling is the same as other joints, and it is connected by a pin shaft, but the pin shaft is different from the chain section
The fitting tolerance is looser than other joints, and the coupling pin can be loaded into the chain joint by tapping with a hand hammer
Remember for future maintenance and disassembly. After installing the second broken chain plate, the chain will continue to be lifted by the above method, until the length of the chain plate is exposed at both ends
When the degree is basically equal, the other end of the chain plate can also be hung on the wire rope to lift the wire rope at the same time, so that the distance between the two joints is gradually reduced
Until you can fit the loose pin.
F, adjust the screw of the tension device and the jack at the end of the frame, tighten the chain plate, make it moderately relaxed, and return the empty chain plate
Natural transition. Further check whether the installation of each part is correct, whether the connecting bolts are fastened reliably, each lubricating part and the reducer box
Whether the lubricating oil has been injected into the inside, whether the motor and electrical device wiring is correct, whether there are forgotten tools and tools in each corner of the machine
Specification
G. After the mechanical part is installed, install the electrical part according to the requirements of apron feeder. Pay attention to protection during installation,
Prevent damage.
Note: In order to facilitate transportation and on-site installation, if the reducer must be removed during transportation or installation of the feeder, be sure to ask the manufacturer
Professional and technical personnel to provide on-site guidance; use a sling to connect the lifting lug and lift the feeder. Adjust the sling to avoid the feeder
At the same time, a certain degree of sling angle is used to keep the equipment in the predetermined installation angle; according to field quarantine protocols,
Ensure that the motor is isolated from the power supply; check the fastness of the fastening bolts of each component and further paint the exposed threads
To show that it has been inspected and properly fastened; remove transport support; inspection vibration
Calibration status of moving screen, refer to the installation drawing; refer to the installation drawing to check the static tilt of the feeder;
Apron feeder installation precautions
① the installation personnel should always abide by the safe operation procedures to prevent accidents;
② transport all parts for installation to the installation site and discharge them neatly according to the scheduled installation position;
③ assemble the head and tail transmission part, and the installation direction of the head transmission part must be consistent with the actual working face.
④ work on the equipment should be carried out in accordance with the site safety procedures, after the equipment is stopped and the feeding system is isolated.
Before installation, clean all components to remove dirt. Transportation equipment and related tools, measuring tools, etc. Are ready.
