Utility model content
For defect and the deficiency of above existence, the utility model utilizes the positive acting power of mandril of lifting jack and opposition to achieve dismounting and the installation function of pin, simple to operate, reduce operating personnel high-altitude and use the security risk brought of sledgehammer and labour intensity, jack handling safety, laborsaving, increase work efficiency.For this reason, a kind of horse head pin of pumping unit rapid dismounting apparatus is designed.
A kind of horse head pin of pumping unit rapid dismounting apparatus, comprises pin cylinder, liner plate, support, jack, base plate and top cylinder, and described pin cylinder is greater than horse head pin external diameter by internal diameter and is highly that the cylinder steel pipe of horse head pin mid-height is formed; Described liner plate is the steel plate that diameter is greater than pin cylinder, and concentric with pin cylinder, and the two employing is welded to connect, and described liner plate can be arranged along described support vertical with moving; On described mandril of lifting jack, plane has one through the wedge-shaped slot in the center of circle, for connecting top cylinder (8), is connected bottom jack with described bed bolt.
Further, respectively there are two circular holes described pin cylinder both sides, and for fixing ejector pin, ejector pin is a U-shaped rod iron, can insert from pin cylinder or extract.
Further, described support comprises three round steel, and three round steel middle parts respectively have a keyway fixing for bayonet lock insertion, realize restriction liner plate moving range; Bayonet lock is U-shaped steel plate, and there is an annulus at rear portion.
Further, be connected in the middle part of described base plate with jack, base plate is provided with in 120 ° of spaced screws, to be threaded with support.
Further, described top cylinder is the cylindrical steel bowl of a hollow, and internal diameter is greater than horse head pin external diameter, coordinates be connected bottom the cylinder of top in wedge shape with plane on mandril of lifting jack.
The utility model has compact conformation, the advantage such as reasonable in design.Adopt jack to be power source in operation, reduce the requirement to operating space and operating personnel's technical quality, decrease high-altitude and use the security risk brought of sledgehammer and labour intensity.Application of the present utility model can be increased work efficiency, and is conducive to the formulation of oil field operation construction standardization, has very wide application prospect.

Detailed description of the invention
As shown in Fig. 1 (a-h), Fig. 2, the utility model comprises pin cylinder 1, ejector pin 2, liner plate 3, support 4, jack 5, base plate 6, bayonet lock 7, top cylinder 8, keyway 9 and horse head pin 10.Described pin cylinder 1 is greater than horse head pin 10 external diameter by internal diameter, is highly that the cylinder steel pipe of horse head pin 10 mid-height is formed, when completing horse head pin dismounting pin be ejected after reception work, respectively there are two circular holes pin cylinder both sides, for fixing ejector pin 2.Described ejector pin 2 is that a circular rod iron is bent into U-shaped rod iron, inserts or extract pin cylinder 1 as required.Described liner plate 3 is annular steel plates that diameter is greater than pin cylinder 1, concentric with pin cylinder 1, and the two adopts welding manner to connect.Described support 4 is by along the circumferential direction 120 °, the interval arrangement of three round steel, connecting lining plate 3 and base plate 6, described liner plate 3 can move both vertically along support 4, and it is fixing that support 4 three round steel middle parts respectively have a keyway 9 to insert for bayonet lock 7, realizes the function of restriction liner plate 3 moving range.Jack 5 is power sources of horse head pin attaching/detaching apparatus, is connected bottom jack 5 with base plate 6 bolt, and on jack 5 push rod, plane has one through the wedge-shaped slot in the center of circle, for connecting top cylinder 8.Described bayonet lock 7 is U-shaped steel plates, and there is an annulus at rear portion, prevents loss for tether, is fixed in the keyway 9 of support 4 when bayonet lock uses.Described top cylinder 8 is cylindrical steel bowls of a hollow, and internal diameter is greater than horse head pin 10 external diameter, and foot wedges is connected with jack 5 push rod.Base plate 6 adopts with support 4 and is threaded.
During dismounting horse head pin 10, liner plate 3 is drop to below keyway 9 along support 4, bayonet lock 7 is snapped in keyway 9, ejector pin 2 is extracted, and is placed on above horse head pin by pin cylinder 1, makes the two with one heart, jack 5 push rod is concentric with horse head pin, now operates jack 5, makes push rod increase, under the positive acting power of mandril of lifting jack, along with the rising of push rod, horse head pin is headed into pin cylinder 1, pushes up when ejecting completely to horse head pin, take out horse head pin, complete unloading process.
When horse head pin 10 is installed, shown in composition graphs 2, first horse head pin 10 is vertically put into fixing hole, liner plate 3 rises to top along support 4, insert ejector pin 2, top cylinder 8 is connected with jack 5 push rod, is placed on above horse head pin by pin cylinder 1, top cylinder 8 is concentric with horse head pin fixing hole, operation jack 5, under the active force of jack 5 push rod, along with push rod declines, horse head pin 10, by ejector pin 2 oppositely press-in top cylinder 8, completes installation process.
