Description
Technical field
The utility model relates to mechanical field, particularly relates to the attending device of Belt Conveying machinery, particularly a kind of permanent magnet suspension tightening device for belt cleaner.
Background technology
In prior art, the clearing apparatus of coal mine conveying belt is made up of blade and tightening device.Blade is for striking off the foreign material on load-transfer device, and tightening device keeps blade to the pressure of load-transfer device.Tightening device uses rubber spring, but rubber creep-resistant property is poor, easily aging, and can environmental pollution be caused, the tensile force decay provided is very fast, blade and belt adhesive force are not after used a period of time, cause cleaning clean, and blade more easily wear and tear.
Utility model content
The purpose of this utility model is to provide a kind of permanent magnet suspension tightening device for belt cleaner, to solve in prior art tensile force when tightening device adopts rubber spring and to decay fast technical matters.
In order to achieve the above object, the utility model adopts following technical proposals:
A kind of permanent magnet suspension tightening device for belt cleaner, by support, blade installation shaft and magnet ring are formed, wherein, through hole is provided with on the upside of described support, a screw rod is provided with in described through hole, the upper end of described screw rod is provided with a pressure adjusting nut, magnetic shield and magnet ring seat is also provided with between pressure adjusting nut and the upper end of magnet ring, described magnet ring to be fixed by bolts on magnetic shield and to be set on screw rod, and between support upper side and pressure adjusting nut, the lower end of screw rod extends in support, the lower end of screw rod is connected with a screw sleeve, a bearing pin is provided with in described screw sleeve, described bearing pin is through the waist type guide groove in one end of a connecting rod, one end of described blade installation shaft is connected with the side of support by bearing, this one end of blade installation shaft extends in support, the other end of described connecting rod is connected with this one end of blade installation shaft by set pin.
Further, described support is made up of channel-section steel and is provided with bolt of rear end plate.
Further, the downside of described support is connected with dowel bolt, and described dowel bolt passes perpendicularly through the screw in the downside of support, and dowel bolt is provided with lock nut.
Compared with prior art, the utility model has following substantive distinguishing features and advantage:
The utility model utilizes permanent magnet suspension mechanism and leverage to continue to provide pressure to sweeper blade, can provide comparatively constant tensile force, ensures that blade and belt are fitted enough tight.The magnetic of this permanent magnetic ring not easily disappears, not easily aging, can not cause environmental pollution.Only the very little power spanner of need turns the power that pressure adjusting nut just can make two magnet rings provide enough large, and the size of power can be regulated by the spacing changing two magnet rings, and the size of amount of compression can be weighed by a scale, therefore regulates very convenient.

Detailed description of the invention
With specific embodiment, the utility model is further described below:
As depicted in figs. 1 and 2, a kind of permanent magnet suspension tightening device for belt cleaner, by support 17, blade installation shaft 11 and magnet ring 5 are formed, wherein, through hole is provided with on the upside of described support 17, a screw rod 8 is provided with in described through hole, the upper end of described screw rod 8 is provided with a pressure adjusting nut 2, the top of described pressure adjusting nut 2 is provided with a jam nut 1, magnetic shield 4 and magnet ring seat 3 is also provided with between pressure adjusting nut 2 and the upper end of magnet ring 5, described magnet ring 5 to be fixed on magnetic shield 4 with bolt 6 and to be set on screw rod 8, and between support 17 upper side and pressure adjusting nut 2, the lower end of screw rod 8 extends in support 17, the lower end of screw rod 8 is connected with a screw sleeve 9, a bearing pin 15 is provided with in described screw sleeve 9, as shown in Figure 3, described bearing pin 15 is through the waist type guide groove in one end of a connecting rod 10, one end of described blade installation shaft 11 is connected by the side of bearing with support 17, this one end of blade installation shaft 11 extends in support 17, the other end of described connecting rod 10 is connected with this one end of blade installation shaft 11 by set pin 12.
Described support 17 is made up of channel-section steel 16 and is provided with bolt of rear end plate 7.
The downside of described support 17 is connected with dowel bolt 14, and described dowel bolt 14 passes perpendicularly through the screw in the downside of support 17, dowel bolt 14 is provided with lock nut 13.
Working process of the present utility model is as follows:
Support 17 is connected with load-transfer device frame by bolt of rear end plate 7, is first unscrewed by bolt of rear end plate 7, then twists dowel bolt 14, support 17 is moved up, after determining location-appropriate, tighten lock nut 13 and dowel bolt 14 is locked, then tighten bolt of rear end plate 7 with fixed support 17.Blade installation shaft 11 and connecting rod 10 are connected as a single entity with set pin 12 when free and stable state by two magnet rings 5.Then make two magnet rings 5 close with spanner turn pressure adjusting nut 2, and screw rod 8 moves up under the effect of magnet ring 5 and pressure adjusting nut 2, by being with cutting blade installation shaft 11 to rotate under the effect of screw sleeve 9 and connecting rod 10 and set pin 12, thus provide tensile force for the blade in blade installation shaft 11.Because connecting rod 10 is provided with waist type guide groove at the connecting portion of itself and screw sleeve 9, therefore screw rod 8 can move up and down.Pressure adjusting nut 2 is tightened after determining in power position to be tensioned.
