2: Structural Overview and Function
: Structure
The mechanical structure of the roller frame is as shown in the figure. It mainly consists of the floating roller component (), the base component (), the gland () and Grease nipple () consists of.
: Rotating shaft: Main support beam: Wheel axle: Round nut: Tapered roller bearing ()
: Bearing sealing cover: Support frame: Cross beam: Roller: Lifting eye screw
During use, If the roller needs to be installed or replaced, please lift the roller and the axle out of the support frame, loosen the round nut and the bearing sealing cover, take the axle out of the roller, install the bearing in the new roller, and install the axle into the bearing. , use a round nut to tighten the bearing. When installing, ensure that the round nut has a certain pre-tightening force on the bearing to ensure that the roller rotates easily on the axle. Inject appropriate grease according to the ambient temperature of use. After assembly, install the rollers together with the rollers into the support frame.
Three: Main technical parameters
Model:
Adaptable pipe diameter:
Single wheel rated load-bearing load:
Overall machine weight: light and heavy
Roller material: Steel core polyurethane coating
Four: Use, care and maintenance
Please read the instruction manual before using the equipment.
. Before using the equipment, please do the following:
. Check whether all parts and components are complete. If there are any missing parts, they need to be replaced immediately.
b. Check whether the added grease meets the specified requirements.
. Check whether the fasteners are loose. Check whether there are open welding parts in the structural welding parts. If there are open welding, etc., welding repairs need to be carried out immediately.
. Check whether the roller rotates flexibly and whether there are any defects such as degumming or cracking. If any, please replace it immediately.
: Lubrication
The light roller bracket is lubricated with grease. The lubrication parts are the bearings at both ends of each roller and the grease nipple at the rotating shaft. Use different greases according to different working environments.
:#General lithium-based grease (B) has good water resistance, mechanical stability, corrosion resistance and oxidation stability. It is suitable for lubrication of rolling bearings and other friction parts within the working temperature ~℃.
Low-temperature lithium-based grease is suitable for lubrication of bearings and other friction parts in cold areas. The operating temperature is: ℃ ~ ℃.
: Aviation grease, suitable for lubrication of bearings and other friction parts in extremely cold areas, operating temperature: ℃ ~ ℃.
Calculation of safety distance of roller frame:
Example: Steel pipe specification Ф (wall thickness.) Anti-corrosion
(dynamic load) (static load) coefficient
(dynamic load) tons* Coefficient of wheel * frame. tons
(The distance between the two roller racks is less than). tons. meters
(Special note: considering the weight of the anti-corrosion layer, the ground is undulating greatly, and the pipe erection has a large bend, it can be shortened appropriately Erection distance.)
