Abstract
The utility model discloses a limiting device for a vertical roller mill. The limiting device comprises a sliding roller, a spring, an ejector rod and a sliding block, wherein the sliding roller is arranged on a rack, and two ends of the sliding roller are opened; the spring is arranged in the sliding roller in a sleeving manner; the sliding block is internally arranged in the sliding roller and is used for compressing the spring; the sliding block can slide in the sliding roller; and the ejector rod passes through the spring and is connected with the sliding block in the sleeving manner. The limiting device for the vertical roller mill has the advantages that the stability and the safety are higher than those of a hydraulic system, the service life of a vertical mill is prolonged, and the cost is reduced; and furthermore, the limiting device for the vertical roller mill is simple in structure, convenient to install, and low in cost.
Description
Technical field
The utility model belongs to the vertical roller grinder machine of the inorganic material attrition process such as cement slurry, clinker, slag and cinder powder, relates in particular to the stopping means of this equipment.
Background technology
Vertical roll grinder is when work, hydraulic cylinder is undertaken in the process of pressure grinding material by the arm grinder roller mechanism, in the situation that hydraulic system is not in time controlled or the grinding roller that breaks down can collide mill, in order to make the Vertical Mill running safer, must design this stopping means.
What design on traditional grinding roller is only with keeping fixing distance between hydraulic control grinding roller and the mill, yet for the distance between grinding roller as slag mill and the mill itself with regard to little Vertical Mill, be easy to not bump against mill in the situation that hydraulic pressure in time reacts grinding roller, Vertical Mill produced grievous injury! Perhaps in the unexpected out of order situation of hydraulic system, also may make grinding roller strike mill, easily produce potential safety hazard, also can produce threat to the staff.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model has provided a kind of vertical roll grinder stopping means, than hydraulic system stability and safety more, and simple in structure.
Technical scheme: for achieving the above object, the utility model is by the following technical solutions: a kind of vertical roll grinder stopping means, comprise and be installed on the frame and slide cartridge, spring, push rod and the slide block of both ends open, described spring housing is in slide cartridge, described slide block is built in the slide cartridge and compresses described spring, and can slide in slide cartridge, described push rod passes spring, and is socketed with slide block.
As preferably, described push rod adopts with being connected of slide block and is threaded, and the slide cartridge correspondence position is provided with trip bolt, the other end is connected with round steel by sleeve, thereby when need to regulate between grinding roller and the mill apart from the time, realize its position of translational adjustment, the push rod left and right sides thereby the rotation round steel drives the push rod rotation.
As preferably, described spring adopts butterfly spring.
Beneficial effect: compared with prior art, the utlity model has following advantage: more stable safer than hydraulic system, in the service life of prolongation Vertical Mill, reduce cost.And this apparatus structure is simple, and is easy for installation, and cost is also very low.
Description of drawings
Fig. 1 is the mounting structure schematic diagram of the utility model on vertical roll grinder;
Fig. 2 is structural representation of the present utility model.
Wherein, grinding roller 1, rocking arm 2, frame 3, slide cartridge 4, spring 5, push rod 6, slide block 7, trip bolt 8, sleeve 9, round steel 10, lubricating cup 11.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
The utility model is difficult for forming for the such bed of material of similar slag vertical-mill, and thickness of feed layer is little, relatively more difficult control of hydraulic system etc. situation, the stopping means that designs for security consideration.Shown in Fig. 1～2, a kind of vertical roll grinder stopping means, it is to be fixed on the frame by bolt, and corresponding with the rocking arm of vertical roll grinder.It comprises and is installed on the frame and slide cartridge, spring, push rod and the slide block of both ends open, described spring housing is in slide cartridge, described slide block is built in the slide cartridge and compresses described spring, and this slide block has flange just to skid off with the flange of the slide cartridge anti-limited slip block that is interlocked, and slide block can slide in slide cartridge.And push rod passes spring, and is socketed with slide block, and is to be combined by thread, and the slide cartridge correspondence position is provided with trip bolt.And push rod is that round steel connects after passing an end branch sleeve of spring.By lubricating cup slide block is lubricated after the assembling, the rotation trip bolt can make slide block and push rod tightly mesh together.When grinding roller presses down material; rocking arm begins to the push rod of external compression stopping means when the below moves to certain position laterally; push rod can be with together laterally motion of movable slider; and then compress butterfly spring; butterfly spring constantly is subject to slide block pressure; slide block stop motion when pressure is equal with butterfly spring elastic force, and grinding roller stops to press down, and this moment, well the protection mill was avoided the grinding roller bump.
Claims (3)
1. vertical roll grinder stopping means, it is characterized in that: comprise being installed on the frame and slide cartridge, spring, push rod and the slide block of both ends open, described spring housing is in slide cartridge, described slide block is built in the slide cartridge and compresses described spring, and can in slide cartridge, slide, described push rod passes spring, and is socketed with slide block.
