19 Liu Sushan Yang Bing peak (
Hebei apple music flour machinery group co. , LTD. )
The large and medium-sized flour mill processing plant specifications basic configuration is 1000 mm mill, even larger, single roller weighing over 350 kg.
Mill roller disassembly maintenance on a regular basis is one of the flour mills indispensable work.
Roller disassembly and transportation auxiliary tool is indispensable, so there will be a variety of which has the function of lifting, transportation tools -
-
Roller disassembly car.
Here introduces a kind of economical and practical, simple operation and easy to use tool cart, we named the discharge roller buggy, hereinafter referred to as' discharge mill car.
1, the discharge mill car car appearance is square shape, the car floor, columns, and the car bearing plate adopt square tube welding, high bearing capacity, is not easy to deformation.
At the bottom of the design has four universal casters, carrying heavy (
Roller)
After, can move freely;
Direction control flexibility.
Support the bumper can at any time to install and remove, transport insurance at the time of the mobile security role.
Elongation arm is deep into the mill shell, make the roller along it moved to the car the two sticks on the bearing plate.
Lever is in roller sports to elongate arm, center of gravity has not been placed in the car on the bearing plate, operators need to keep balance of the car to use, can maintain the car safety.
Set blocks are used to fixed roller position, prevent roller rolling to the outside of the floors of car accidents.
When the handle is to move the car armrest, can push and pull to move the car.
Balance support is when removing roller have increased the car support base design, roller can with their feet when elongation arm to keep the car on a balance of support and balance.
Can balance the lower end of the support column when the car is impacted by the roller rolling play a supporting role, make the car balance, to prevent the car in reverse.
Lifting mechanism is a manual jack can lift 500 kg, by a pressure rod can easily take-off and landing, take-off and landing height is 150 mm.
Discharge mill car shape structure is shown in figure 1.
2, working principle of the car using discharge grinding car unloading is the purpose of grinding roller from shell internal moving out, sent to the designated place.
To remove grinding roller shell, must first put the mill roll up, the car bearing plate must be lifting, he can remove the roller, can also move.
This equipment has two main functions: lifting and moving.
Lifting function by jack namely manual hydraulic pump to achieve;
Mobile capabilities by four universal casters.
3 cars, discharge mill roller is removed using the preparation, such as removing the body peripheral guard board, grinding, grinding fixed on both ends of the roller bearing of the bolts are removed, can use rollers to move the car.
First remove the support in the bumper, make the car bearing plate forward, moving forward the car, the car in the bore into people to grinding mill elongation arms down to the bottom of the roller, the small car has stopped, the rear wheels when necessary padded block, make the car not moving back automatically after compression, to ensure safety, as shown in figure 2.
To move up and down pressure hydraulic pump operating lever, making the oil pump lifting lever, rises the car bearing plate and the mill roller carried from ontology, to the car bearing plate increases after reaching level, slowly out of the car.
At this time, for the sake of safe and reliable, the support bumper, inserted into the holes in the front vehicle.
On the other side of the roller without limit block padded prevent mobile dedicated stop block, so that you can freely and safely driving the car, to where it is needed, as shown in figure 3.
Discharge mill car structure is simple, convenient and flexible for use.
Especially the manual operation, not electricity, in flour mills outage maintenance equipment, still can use convenient.
Discharge mill car is one of the flour mills often use economic applicable auxiliary tool.
