Recently, many friends left messages asking how to install a certain type of crushing equipment or screening equipment, or how to install a certain part. For large-scale grinding equipment, the editor does not recommend to assemble or repair on the basis of not understanding. In place, small details may cause major problems in production, so it is best to contact professional equipment personnel to operate.
However, if you want to have a certain understanding of the structure and installation of the equipment, the editor is happy to communicate with you. This article takes the revolving crushing as an example to introduce the installation steps and precautions of the 5 parts of the lower frame, transmission part, eccentric shaft sleeve part, middle frame, crushing cone part and beam.
1. Installation of the lower rack
The installation of the lower rack is the basis for equipment installation. Install the lower rack on the foundation first, and the equipment must be consistent with the foundation during installation. A gap of not less than 30mm should be kept between the base of the lower frame and the foundation due to secondary grouting. Tighten the anchor bolts after the second grouting to ensure the stability of the equipment.
2. Installation of the transmission part
The installation of the transmission part is related to the operation of the equipment. Therefore, when installing, it must be noted that the centers of the two copper sleeves must always be kept at the same horizontal line without deviation. The radial gap between the copper sleeve and the shaft must be strictly in accordance with the instructions of the equipment manual. Within a certain range. When installing the drive shaft, it is necessary to add an appropriate amount of gaskets between the flange of the drive housing and the frame to adjust the position of the bevel gear to meet the product design requirements.
3. Installation of eccentric shaft sleeve
Special attention should be paid to the installation process to protect the smoothness and integrity of the friction surface of the babbitt alloy layer. Check whether the tooth tip clearance meets the requirements after installation, and correct it in time if any abnormality is found. The size of the gap can be adjusted by changing the number of adjustment shims.
4. Installation of the middle rack
The installation of the middle frame needs to be calibrated through the upper flange of the lower frame. Before installation, it is necessary to make sure that the gap between the flanges of all the taper surfaces is equal, and the error should be less than 0.5mm. The gap between the upper and lower joint surfaces is generally about 15 mm.
When installing, make sure that the pins are tightened. After the machine has been running for a period of time, tighten the pins one by one to make all the pins on the circumference evenly stressed, strengthen their stability, and ensure the normal operation of the equipment.
5. Installation of crushing cone and beam
Two ways:
(1) The crushing cone is installed separately
Use the lifting ring on the shaft to hoist the crushing cone into the frame, and then place wooden pads on the ribs on the lower part of the frame to support the cone, then install the beam, and install the nut and jacket on the upper end of the spindle, and finally install the cap , Then take out the wooden mat and wooden wedges.
(2) The crushing cone is installed together with the beam
That is, the beam and the crushing cone are installed in a special pit in advance, and then installed in the frame together. When lifting the crushed cone and beam components, pay attention to the hoisting method. Wire ropes must be used to hang on the beam of the beam to prevent accidents during the hoisting process. The crushing wall of the crushing cone must be pressed tightly to prevent loosening. Before pressing, apply dry oil to the lower space of the fixed ring (pressing plate) and the anastomotic bolts to prevent rust or corrosion and affect the life of the equipment.
