Description
Technical field
This utility model relate to vertical mill installation, overhaul, maintenance aspect, be specifically related to a kind of Simple Vertical grinding roller sleeve and remove and install device.
Background technology
Vertical mill is the conventional production equipment on cement producing line, as: produce the L48.4 Loesche mill of raw material, produce the HRM2200M vertical mill of coal dust, its major wear item roller shell needs periodically to be replaced safeguarding, owing to its size is relatively big, heavier mass, the restriction of mill local environment is (such as: position is high in addition, space is little), it removes and installs and there is the biggest inconvenience.Although L48.4 Loesche mill is equipped with specific purpose tool, but its use is cumbersome, wastes time and energy in nervous service work.
Utility model content
It is the conventional production equipment on cement producing line that the purpose of this utility model is aiming at vertical mill, as: produce the L48.4 Loesche mill of raw material, produce the HRM2200M vertical mill of coal dust, its major wear item roller shell needs periodically to be replaced safeguarding, owing to its size is relatively big, heavier mass, the restriction of mill local environment is (such as: position is high in addition, space is little), it removes and installs and there is the biggest inconvenience.Although L48.4 Loesche mill is equipped with specific purpose tool, but its use is cumbersome, the deficiency wasted time and energy in nervous service work, and provides a kind of Simple Vertical grinding roller sleeve to remove and install device.
This utility model includes main lever arm, a pair bracket and auxiliary lever arm, main lever arm top is arranged with a pair hanger, a pair pallet top is respectively equipped with regulation hanger, and on a pair bracket, have installing hole and lifting pawl, a pair bracket is movably arranged on main lever arm two ends by installing hole respectively, auxiliary lever arm is arranged on bottom main lever arm, and auxiliary lever arm and main lever arm square crossing.
It also has a pair hydraulic jack, a pair hydraulic jack to be movably arranged on auxiliary lever arm two ends respectively.
Described main lever arm is respectively arranged at two ends with projection, and the installing hole side of a pair bracket is respectively equipped with block, and the aperture of the installing hole of the pair of bracket is more than the diameter of main lever arm.
This utility model advantage is: this device makes the installation or removal of vertical mill roller shell convenient and swift, it can be avoided that bracket loosens to drop causes contingency during installation or removal.
Accompanying drawing explanation
Fig. 1 is this utility model front view structural representation.
Fig. 2 is this utility model side view structural representation.
Detailed description of the invention
As shown in Figure 1, 2, this utility model includes main lever arm 1, a pair bracket 2 and auxiliary lever arm 3, main lever arm 1 top is arranged with a pair hanger 4, a pair bracket 2 top is respectively equipped with regulation hanger 5, and on a pair bracket 2, have installing hole and lifting pawl, a pair bracket 2 is movably arranged on main lever arm 1 two ends by installing hole respectively, and auxiliary lever arm 3 is arranged on bottom main lever arm 1, and auxiliary lever arm 3 and main lever arm 1 square crossing.
It also has a pair hydraulic jack 6, a pair hydraulic jack 6 to be movably arranged on auxiliary lever arm 3 two ends respectively.
Described main lever arm 1 is respectively arranged at two ends with projection 7, and the installing hole side of a pair bracket 2 is respectively equipped with block, and the aperture of the installing hole of the pair of bracket 2 is more than the diameter of main lever arm 1.
Operation principle: before installing/dismounting grinding roller sleeve, a pair bracket 2 is each passed through projection 7 and is arranged on main lever arm 1 two ends, auxiliary lever arm 3 is arranged on bottom main lever arm 1, a pair hydraulic jack 6 is slidably mounted on auxiliary lever arm 3 two ends respectively, and keep auxiliary lever arm 3 and the perpendicular cross-like of main lever arm 1, the when of making lifting, the power on auxiliary lever arm 3 and main lever arm 1 is kept in balance, a pair hanger 4 that crane drag-line is each passed through on main lever arm 1.When grinding roller sleeve is installed, crane is sling main lever arm 1, a pair bracket 2 is made to lay respectively at above grinding roller sleeve, the lifting pawl of a pair bracket 2 is put into bottom grinding roller sleeve respectively, and the regulation hanger 5 on a pair bracket 2 is pulled with electric block, a pair bracket 2 is made to be clamped on grinding roller sleeve, then a pair hydraulic jack 6 position on auxiliary lever arm 3 is adjusted, the other end making a pair hydraulic jack 6 props up the top of grinding roller sleeve respectively, press a pair hydraulic jack 6, grinding roller sleeve is firmly pressed between a pair bracket 2 and auxiliary lever arm 3, then it is lifted to need position to be mounted, a pair hydraulic jack 6 is unclamped after installing, and a pair bracket 2 is unclamped to two ends.
When dismantling grinding roller sleeve, owing to roller shell uses the time longer, coordinating relatively tight with roller core fitting surface, the other end of a pair hydraulic jack 6 is the roller core first propping up vertical mill, and balance applies pressure so that roller shell loosens, and then repeats step when installing and lifts by crane.
During this device of crane loading to grinding roller sleeve, a pair bracket 2 is due to not fastening, may be from main lever arm 1 two ends landing, main lever arm 1 is respectively arranged at two ends with projection 7, and the installing hole side of a pair bracket 2 is respectively equipped with block, a pair bracket 2 is due to gravity, when sliding into the position of projection 7 to two ends, block can be blocked by projection 7, it is to avoid a pair bracket 2 drops generation contingency from main lever arm 1.
