Abstract
The utility model discloses an electromagnetic anti-theft brake special for pumping units, comprising a pumping unit shaft, and shaft sleeves fixedly connected with the pumping unit; the upper sleeve of the shaft sleeves of the pumping unit shaft are sleeved by a flange disk, a push disk and a magnetic yoke which are mutually connected and fixed by bolts; a brake disk connected with the pumping unit shaft by a diving key is provided between the flange disk and the push disk. An energizing coil is arranged in the magnetic yoke; an armature is arranged at outer side of the magnetic yoke of which inner side is fixed with an inward extended guide pillar across the magnetic yoke; a pressing spring is sleeved on the guide pillar. When working, the energizing coil powers on and generates magnetic field, which has the armature sucked to the magnetic yoke; through the guide pillar, the brake disk is pushed by the push disk, moves along the shaft, and is contacted with the flange disk to generate friction; the pumping unit is braked, and thus replaces the traditional hand brake. The utility model has simple operation, good anti-theft function, and convenient automatic management.
Description
Technical field
The utility model relates to a kind of magnetic clutch---break, the special-purpose electromagnetism anti-theft brake of especially a kind of pumping unit of oil field.
Background technique
Set break is traditional manual brake on the pumping unit in oil field at present, and operation is comparatively heavy, is not easy to automatic management, and antitheft effect is also relatively poor, does not also see the precedent of installing electromagnetic brake on pumping unit at home.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, provides a kind of pumping unit special-purpose electromagnetism anti-theft brake, makes it simple to operate, and antitheft making good use of is convenient to automatic management.
For solving the problems of the technologies described above, the utility model adopts the basic design of technological scheme to be: the special-purpose electromagnetism anti-theft brake of a kind of pumping unit, comprise the pumping unit rotating shaft, in the pumping unit rotating shaft, be provided with the axle sleeve that is fixedly connected with it, be with the fixing flange plate that is inter-connected via a bolt joint on this axle sleeve, push-plate and yoke, be provided with the brake disc that is connected by feather key with the pumping unit rotating shaft between this flange plate and the push-plate, be with Returnning spring on the bolt between this flange plate and the push-plate, be provided with field coil in the described yoke, the outer side of yoke is provided with corresponding with its end and has the armature in gap, this armature inner side surface is fixed with and passes the guide pillar that yoke extends internally, be with stage clip on the guide pillar, the inner of this guide pillar contacts with push-plate.The described guide pillar that is fixed on the armature is 2-6.Described bolt is more than 3.Has the gap between described brake disc both sides and flange plate and the push-plate respectively.
After adopting such scheme, the utility model compared with prior art has following beneficial effect:
Because the special-purpose electromagnetism anti-theft brake of the utility model pumping unit, utilize the electromagnetic braking principle, as long as energising, field coil just produces magnetic field, armature is inhaled to yoke, and promote push-plate and brake disc moves vertically by its guide pillar, brake disc is contacted with fixing flange plate produce frictional force and reach the purpose that pumping unit is braked.Effectively substituted traditional manual brake, and had the following advantages:
1) simple to operate;
2) under the rugged environment in oil field, can play good antitheft effect;
3) be convenient to form automatic management gradually with all petroleum machineries;
4) the Applicable temperature scope is wide.
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe in further detail.
Description of drawings
Fig. 1 is the structural representation of the special-purpose electromagnetism anti-theft brake of the utility model pumping unit
Embodiment
As shown in Figure 1, the utility model is the special-purpose electromagnetism anti-theft brake of a kind of pumping unit, its structure comprises pumping unit rotating shaft 10 and the axle sleeve 20 that is fixedly connected with it, adopt key connecting or interference fit to connect, be with on the axle sleeve 20 of this pumping unit rotating shaft 10 by bolt 4 interconnective fixing flange plate 1, push-plate 3 and yoke 5, be provided with brake disc 2 between this flange plate 1 and the push-plate 3, this brake disc 2 is connected with pumping unit rotating shaft 10 by feather key 11, and brake disc 2 can endwisely slip in pumping unit rotating shaft 10 upper edges.Be with Returnning spring 9 on the bolt 4 between flange plate 1 and the push-plate 3, this bolt 4 is provided with more than 3, and present embodiment is provided with 4.Between the both sides of described brake disc 2 and flange plate 1 and push-plate 3, have gap 13 and 14 respectively.Be provided with field coil 12 in the described yoke 5, the outer side of yoke 5 is provided with corresponding with its end and has the armature 6 in gap 15, the inner side surface of this armature 6 is fixed with the guide pillar 7 that passes yoke 5 and extend internally, this guide pillar 7 is provided with 2-6, present embodiment is provided with 4, be with stage clip 8 on it, this guide pillar 7 can slide in yoke 5 vertically, and the inner of guide pillar 7 contacts with push-plate 3.
The working principle of the special-purpose electromagnetism anti-theft brake of the utility model pumping unit: when the field coil 12 of break is switched on, field coil 12 produces magnetic field, armature 6 is inhaled to yoke 5, by four guide pillars 7 and compression press spring 8, push-plate 3 is moved vertically, push brake disc 2 to, and make the brake disc 2 generation frictional force that contacts with flange plate 1, because of flange plate 1 is fixed, therefore pumping unit rotating shaft 10 is by brake disc 2 brakings, thereby reach the purpose of pumping unit braking, when having only outage, could lean on the elastic force of Returnning spring 9 and stage clip 8 that push-plate 3 and armature 6 are resetted.The special-purpose electromagnetism anti-theft brake of the utility model pumping unit effectively substitutes traditional manual brake, and has simple to operate, the antitheft effect of making good use of, be convenient to automatic management.
