The Installation of Belt bucket elevator's belt and hopper
(1)Installation of rubber belt shall be noted that the rubber belt has a transverse steel wire surface (anti-tearing layer) in contact with the head wheel and tail wheel, and no transverse steel wire surface shall be equipped with hopper.Before installing the tape, make sure that the friction contact surface and hopper contact surface are not installed in reverse.When installing the rubber belt, install the rubber belt outward to the hopper, and first lift the tensioning device to the position close to the upper block and reinforce it. (2)Before traction of rubber belt, all protruding parts such as off-balance switch must be removed. Before supply, the rubber belt is wound on the wood core to prevent damage of the rubber belt.At the same time, the maintenance section or the door hole of the tail of the machine is selected as the entrance to the cylinder. In order to reduce friction, the corresponding belt roller is installed in the hole.
(3)Hopper installation and the installation of tape at the same time the way to save time and more efficiency. According to the actual, the position of the hopper in the cylinder body is narrow, in-cylinder is installed on the back of the bolt installation is very difficult, therefore use adhesive tape in the ground and from the access door hole with tape drawing into the cylinder body, hopper installation bolt fastening, this method can guarantee good quality and at the same time to many colleagues hopper installation work.
(4)Using slow winch as a lifting tool. The wire rope is pulled down from the head barrel to the tail part or maintenance section and then connected with the traction fixture so that the traction tape will not tear the tape when it enters the barrel. When pulling the rubber belt, first lift the rubber belt from the maintenance section or the tail of the machine, bypass the head and tail wheel, and connect the rubber belt joint at the top of the assembly section or the head wheel. When the tape is attached, assemble the hopper.
(5)Installation of hopper: there are reserved bolt holes on the tape, and each row of bolt holes corresponds to a hopper. The installation of the hopper shall be carried out in strict accordance with the installation drawings and instructions of the manufacturer of the hopper lift. The installation of the hopper at the joint of the hopper shall not be changed at will. The lap length shall span three hoppers, and the distance between the connecting bolt axis and the end of the tape shall not be less than 50mm.
Belt joint construction
The belt and hopper of the belt bucket elevator must be connected immediately after installation. This process is very important. If the connection is loose, the belt will slip and the hopper will shake, and too tight installation will lead to serious wear of rubber belt and head wheel and tail wheel equipment. The length of steel tape should be calculated accurately during installation. When the deviation exceeds a certain value, the length of the tape needs to be adjusted, so the end of the rubber belt joint is often made on site. The manufacturing method and steps of the rubber belt joint are as follows: step 1: lift the tail wheel to the initial adjustment position; Step 2: tape bypasses the tail wheel and prepares to dock at the nose. Step 3: try a combination of the adhesive tape at the head wheel, alignment and determination of cutting position, stripping position and connection bolt hole position; Step 4: tape cut and strip, drilling. Step 5: tightening the bolts.
