Abstract
The utility model discloses a separating device of crank pin and connecting rod of pumping unit used in the oil industry, which can be used in onsite construction of various types of pumping units, and conveniently separates a crank pin and a connecting rod. The device comprises a supporting mechanism and a forcing mechanism, wherein the forcing mechanism is arranged in a support of the supporting mechanism, and the crank pin is separated with the connecting rod through the forcing mechanism. The device has the characteristics of simple operation, convenience, practicality, reliable work and the like, and can greatly reduce the labor intensity of onsite construction personnel, improves the working efficiency, does not need forcing operation, such as ramming, knocking, prizing and the like, reduces the unsafe factors of high altitude dropping objects and the like, protects the device, prolongs the service life of the device, and reduces the manufacturing cost. The fixed width of the device and the width between screw bolts can be adjusted, and the device can be used in various types of the pumping units and has wide application range.
Description
Technical field
The utility model belongs to the maintenance tool of petroleum industry oil production equipment, and particularly oil pumping machine crank pin, connecting rod release unit can use in the site operation of various model oil pumpers, easily crank pins are separated with connecting rod.
Background technology
Oil pumper is the large-scale oil production equipment of petroleum industry, changes in the process of crank pins at dismounting oil pumper and oil pumper ordinary maintenance, and working procedure is arranged one, the oil pumping machine crank pin be separated with connecting rod.This operation all adopts two kinds of methods in constructing at the scene at present, first kind is knocked crank pins and oil pumper connecting rod with sledgehammer, thereby produce vibration and make it the absent-mindedness disengaging, second kind is inserted gap between crank pins and the oil pumper connecting rod with crowbar, prize disengaging then, or two kinds of methods are used in combination.But above construction method all belongs to strong physical work, dismantles connecting rod especially at the scene, changes in the half high-altitude construction operation of crank pins, and above-mentioned construction method exists more unsafe factor to the workmen.In addition, ramming, strike, prize this rigid operation has in various degree damage to crank pins, connecting rod, shortens the service life of oil pumper equipment.
Summary of the invention
The purpose of this utility model is to make a kind of reliable operation, convenient and practical oil pumping machine crank pin, connecting rod release unit, and convenient construction reduces the unsafe factor that exists in the work progress, and makes it be applicable to the site operation of various model oil pumpers.
Implement the present technique solution and can reach above-mentioned purpose: oil pumping machine crank pin, connecting rod release unit comprise supporting mechanism and force application mechanism, force application mechanism are installed in the support of supporting mechanism.By force application mechanism crank pins is separated with connecting rod.
Has following useful effect after using the utility model: the utlity model has characteristics such as simple, convenient and practical, reliable operation, can reduce site operation personnel's labour intensity greatly, increase work efficiency.Need not to ram, strike, rigid operation such as sled, reduced unsafe factors such as high-altitude junk, for site operation personnel's personal safety provides guarantee.Simultaneously also protect equipment, prolonged the service life of equipment, reduced production cost.Width-adjustable between fixed width of the present utility model and the screw rod can be used for the oil pumper of various models, and is applied widely.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description: referring to accompanying drawing, oil pumping machine crank pin, connecting rod release unit comprise supporting mechanism and force application mechanism, force application mechanism are installed in the support 1 of supporting mechanism.Supporting mechanism comprises support 1, slide block 3 and baffle plate 4, and the two ends of support 1 are provided with baffle plate 4, and slide block 3 is installed in the inboard of baffle plate 4, and slide block 3 is installed on the support 1, can be free to slide on support 1, and fixed width is adjustable, is applicable to the oil pumper of multiple model.Also be provided with stay hook 5 on the outer wall of slide block 3, can be hooked on the connecting rod of oil pumper.Also be provided with slideway 7 on the support 1, about the slideway 7, about run through, can move and install screw rod 2 and can regulate nut 6.Force application mechanism comprises screw rod 2 and nut 6, and nut 6 is installed on the screw rod 2, and screw rod 2 and nut 6 are interspersed in the slideway 7 of support 1, and by rotating screw bolt 2, the reaction force that utilizes this device to produce can separate the crank pins of oil pumper with connecting rod.
When site operation uses this utility model, at first remove the set bolt of connecting rod end, expose bolt hole, these bolts hole face the platen of crank pins.The position that the end of selecting correct position to be hooked on the oil pumper connecting rod stay hook 5 of slide block 3 is connected with crank pins.It is suitable in the bolt hole that aims at the crank pins platen that screw rod 2 symmetry of this device is inserted.Utilize slideway 7 to adjust nut 6 and screw rod 2 simultaneously, make this device fixing.With spanner rotary screw 2, make screw rod 2 hold out against the crank pins platen, the both sides symmetry continues screw rod 2 precessions.Utilize the active force of screw rod 2 precessions, under the reaction force that support 1 and slide block 3 produces, connecting rod can be separated with crank pins, need not to ram, strike, rough operation such as sled, protected equipment, guaranteed operating personnel's safety.
