Description
Technical field
The utility model belongs to oil pumper part of appliance, particularly relates to a kind of closed mule head device of beam pumping unit.
Background technology
Beam pumping unit is domestic main oil extraction in oil field plant equipment, and the horse head of beam pumping unit is circular arc, and using the fulcrum of bearing as round dot, does circular motion, ensures that polished rod is tangent with horse head all the time, makes sucker rod do up and down reciprocatingly rectilinear motion.But the biside plate of horse head has stretched out outside arc plate in traditional mule head device, rupture for preventing from rubbing between wire rope and donkey head lateral plate in the process of motion, so the distance between wire rope and donkey head lateral plate is remained on about 30mm, when sucker rod pumps, wire rope produces certain pressure to arc plate, distant due to donkey head lateral plate and wire rope, so the support force of donkey head lateral plate to arc plate is less, arc plate is easily made to deform, arc plate is once deform, sucker rod misalignment well head, affect the normal work of oil pumper, must support arc plate by increasing a large amount of gussets at present, arc plate is avoided to deform, thus add cost of production.
Utility model content
The purpose of this utility model is: for solving the deficiencies in the prior art, provides the closed mule head device that a kind of structure is simple, reasonable in design, save the oil pumper of material, greatly reduces cost of production.
For achieving the above object, the technical solution of the utility model is:
A kind of closed mule head device of oil pumper, comprise donkey head lateral plate, arc plate, gusset, protect fake and groove, two parallel donkey head lateral plates and arc plate vertical welding, the cambered surface radius of arc plate equals the radius of gyration of horse head, the width of described arc plate is greater than the width between two parallel donkey head lateral plates, arc plate middle part is along its length provided with groove, gusset is arranged between two donkey head lateral plates, gusset and donkey head lateral plate vertical welding, gusset and arc plate vertical welding, protect fake and be arranged on donkey head lateral plate both sides, the described fake that protects comprises pipe, angle steel, arch guard ring, angle steel is welded on the both sides of donkey head lateral plate, pipe is welded in angle steel, the two ends of arch guard ring are welded with pipe respectively.
Further, also comprise support member, support member is arranged on the arc plate on horse head top, and wire rope is walked around support member and is placed on arc plate, and the distance of described wire rope and donkey head lateral plate is 5 ~ 10mm.
Owing to have employed such scheme, the beneficial effects of the utility model are: solve the deficiencies in the prior art, this oil pumper closed mule head device structure is simple, reasonable in design, make simple, save material, for the oil pumper that stroke is identical with polished rod load, the gusset of about 2/3rds can be saved, thus reduce cost of production.

Reference numeral: 1-donkey head lateral plate, 2-arc plate, 3-gusset, 4-protects fake, 5-groove, 6-wire rope, 7-support member, 401-angle steel, 402-pipe, 403-arch guard ring.
Detailed description of the invention
Embodiment 1: composition graphs 1, Fig. 2, comprise donkey head lateral plate 1, arc plate 2, gusset 3, protect fake 4 and groove 5, two parallel donkey head lateral plates 1 and arc plate 2 vertical welding, the cambered surface radius of arc plate 2 equals the radius of gyration of horse head, the width of described arc plate 2 is greater than the width between two parallel donkey head lateral plates 1, 2 the certain supporting roles of donkey head lateral plate 1 pair of arc plate, arc plate 2 middle part is along its length provided with groove 5, gusset 3 is arranged between two donkey head lateral plates 1, gusset 3 and donkey head lateral plate 1 vertical welding, gusset 3 and arc plate 2 vertical welding, 2 the further supporting roles of gusset 3 pairs of arc plates, in order to avoid arc plate 2 deforms by the pressure of wire rope 6, protect fake 4 and be arranged on donkey head lateral plate 1 both sides, prevent wire rope 6 lateral deviation in motion process, the described fake 4 that protects comprises pipe 401, angle steel 402, arch guard ring 403, angle steel 402 is welded on the both sides of donkey head lateral plate 1, pipe 401 is welded in angle steel 402, the two ends of arch guard ring 403 are welded with pipe 401 respectively.
Further, also comprise support member 7, support member 7 is arranged on the arc plate 2 on horse head top, and wire rope 6 is walked around support member 7 and is placed on arc plate 2, and described wire rope 6 is 5 ~ 10mm with the distance of donkey head lateral plate 1.
The closed mule head device structure of described oil pumper is simple, reasonable in design, makes simple, saves material, for the oil pumper that stroke is identical with polished rod load, can save the gusset of about 2/3rds, thus greatly reduce cost of production.
