Description
Technical field
The utility model belongs to the non-metallic material milling equipment, particularly relates to a kind of frame of two roller vertical roller grinders.
Background technology
Vertical roller grinder (abbreviation Vertical Mill) is a kind of energy-conservation milling equipment that is widely used in industries such as cement, electric power, mining, iron and steel at present, and existing two roller vertical mills set up the meter complex structure, because shared with the air channel, function is less.Because the grinding roller quantity of two-roller mill is few; Unbalance loading takes place during running easily; Therefore, many aspects such as the integral rigidity of existing frame, steadiness, balance are difficult to guarantee, cause the grinding machine vibration especially easily; Cause the damage of some parts such as support, the serviceability to Vertical Mill causes harmful effect simultaneously.
Summary of the invention
The utility model provides a kind of frame of two roller vertical roller grinders for solving the technical problem that exists in the known technology; This rack construction is simple, rigidity is strong, solid and reliable, stationarity good, serviceability good, can avoid grinding machine vibration and reduce noise, can strengthen the grinding machine reliability of operation.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of frame of two roller vertical roller grinders; Comprise the base that is cast on the basis; Said base is connected through foundation bolt with the basis; Both sides respectively have been located a support, said support and the welding of said base, and be connected on the basis together through foundation bolt; Be provided with the connection bridge above two said supports, said connection bridge and two said are configured to frame structure; Said internal stent is equipped with stopping means.
Said connection bridge is a case structure.
The both sides of said support have additional gripper shoe; The outside of said gripper shoe runs off said base; The upper end of said gripper shoe is connected bridge welding and connects with said, and the part that the lower end is seated on the said base is welded with said base, and the part that runs off said base is cast in the basis.
Said base is a frame structure, and upper surface middle part is welded with base plate.
Advantage and the good effect that the utlity model has are: through adopting base is cast on the basis; And the form of tower structure is set on base; Make that this housing rigidity is strong, solid and reliable, stationarity is good, serviceability is good, can bear the maximum load of Vertical Mill; Comprising the gravity of undertaking parts such as separator on grinding machine, middle shell, grinding roller, mill, rocking arm, air channel, main reducing gear, and grinding roller is applied to the pressure on the mill when running well.This frame can realize spacing between grinding roller and mill, can also place parts such as main gear reducer and pressurization oil cylinder.And simple in structure, compact, be convenient to make and centering is installed, can avoid the grinding machine vibration and reduce noise, strengthen the grinding machine reliability of operation.Installation is convenient, and easy centering.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: 1, support, 2, stopping means, 3, connect bridge, 4, gripper shoe, 5, base plate, 6, base, 7, foundation bolt, 8, the adjustment bolt.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1～Fig. 2, a kind of frame of two roller vertical roller grinders, it is an integral solder structural member, comprises base 6, support 1, gripper shoe 4, stopping means 2 and is connected bridge 3.
Above-mentioned base 6 adopts the general frame forms, and upper surface middle part is welded with base plate 5, and base plate 5 is positioned at the center of base 6, and as the benchmark of grinding machine, it is bearing the gravity from the pressure of grinding roller and mill, main reducing gear.
Vertical Mill at first will be put into the concrete foundation trench of one-time-concreting with base 6 when mounted, behind the centering location; Can carry out back-grouting, it is imbedded among the concrete, treat concrete setting after; Base 6 just becomes one with concrete foundation, can bear the maximum load of Vertical Mill jointly.
Two supports 1 lay respectively at the both sides of base 6 upper surfaces, and support 1 is seated on the concrete foundation through running through of foundation bolt 7 with base 6 together, during installation, treat support 1 centering after, itself and base 6 are welded as a whole.It can be directly with the weight transfer such as separator, middle shell, air channel, grinding roller and rocking arm on Vertical Mill top on base 6 and basis.It set inside decelerator, pressurization oil cylinder and pipe fitting thereof, when grinding machine runs well, can the pressure of grinding roller be directly delivered among base 6 and the grinding machine basis.The hydraulic pressurization pipeline also can be passed with the oil cylinder that pressurizes by support 1 and be connected in addition.
Connecting bridge 3 is box-like body, is positioned at the top of frame, through the firm welding of upper and lower bilayer, makes the support 1 on itself and both sides constitute a complete frame structure.Its rigidity and intensity are all very strong, have increased the rigidity of whole frame greatly, thereby have guaranteed the stationarity of frame.The effect that connects bridge 3 is the support 1 that connects both sides, gravity such as separator, middle shell, air channel, grinding roller and rocking arm with support 1 together support, and is bearing roll-in.
The upper and lower part of gripper shoe 4 respectively be connected bridge 3 and weld together with base 6, be positioned at the both sides of support 1, its outside runs off base 6; Below it, be provided with adjustment bolt 8, during installation, behind the centering; The part that runs off base is imbedded concrete foundation, and with the part and base 6 welding that are seated on the base 6, gripper shoe 4 and base 6 are born the load of grinding machine jointly; Can make whole frame keep poised state, play balance and reinforce the effect of supporting.
The operation principle of the utility model:
Vertical Mill is between on-stream period; The gravity of parts such as the separator on it, middle shell, grinding roller, mill, rocking arm, air channel, main reducing gear; And grinding roller is applied to the pressure on the mill; All drop on the frame, it is not only undertaking the maximum load of grinding machine, will guarantee grinding machine continuous running safely and smoothly simultaneously.At the mill running initial stage, the stopping means control by frame can make between grinding roller and the mill to keep certain clearance, forms stable material bed.When the operation after a while of grinding machine warp; Grinding roller and mill are because wearing and tearing have appearred in the friction of material; Make its gap become big, material bed uneven thickness, performance indications such as the output in the time of will moving grinding machine, fineness, power consumption, mill efficiency, vibration values produce very big influence; Adjust this gap through the stopping means of frame, can make grinding machine keep normally running reposefully.
Although combine accompanying drawing that the preferred embodiment of the utility model is described above; But the utility model is not limited to the above-mentioned specific embodiment, and the above-mentioned specific embodiment only is schematically, is not restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the utility model.
