Abstract

The utility model relates to an device for detaching crank pin on crank of cooker hood, and comprises a bottom board with a jam-bolt bore and a sleeve with female screw on the free end, an ejecting screw, a sleeve locking bolt, a sleeve locknut, a gasket of sleeve locking bolt, a locking bolt of bottom board, a locknut of bottom board and a snap-gauge of U-shaped bolt; the ejecting screw connects the sleeve screw-thread among them; the sleeve locking bolt and the sleeve locknut are installed on the sleeve through the gasket of sleeve locking bolt; the locking bolt an locknut of bottom board are installed on the bottom board; the snap-gauges of U-shaped screw bolt are locked on the sleeve locking bolt and the locknut of bottom board respectively; the utility model dismounts the crankpin from the pumping unit crank with the help of spiral driving force which is produced by the rotary between ejecting screw and sleeve which are connected through mutual screw-thread, so the utility model not only saves labor but also gets high efficiency, and only needs two worker to operate.

Description

Be used to dismantle the device that the crank-pin on the oil pumping machine crank is used

Technical field

The utility model relates to a kind of provision for disengagement, particularly relates to the device that a kind of crank-pin that is used to dismantle on the oil pumping machine crank is used.

Background technology

Crank-pin on the oil pumping machine crank is added its work under bad environment owing to need bear and transmit huge strength, so crank-pin is often blocked and/or becomes rusty dead among the crank pin hole on the oil pumping machine crank; At present, when needs disassemble crank-pin on oil pumping machine crank, can only rely on the workman to beat crank-pin for a long time with iron hammer, can disassemble until it being struck Song Houcai, beat consumed time a few hours at least, tens hours at most, and need at least 5 strong labour powers' wheels roll up battle array, its working strength is very big, and very low of operating efficiency.

Summary of the invention

The purpose of this utility model provides a kind ofly needs that number is few, working strength is little, high efficiency be used to dismantle the device that the crank-pin on the oil pumping machine crank is used.

The purpose of this utility model is achieved in that the device that a kind of crank-pin that is used to dismantle on the oil pumping machine crank is used, and it includes one and is set with a locking screw keyhole on it and two free ends have the base plate of the sleeve of internal thread, an ejection bolt, a sleeve clamping screw, a sleeve locking nut, a sleeve clamping screw pad, a base plate clamping screw, a base plate locking nut and two U bolt clamps; Wherein ejection bolt and bush whorl link together; Sleeve clamping screw and sleeve locking nut are arranged on the sleeve by sleeve clamping screw pad; Base plate clamping screw and base plate locking nut are arranged on the base plate by the locking screw keyhole on the base plate; Two U bolt clamps are connected to respectively on sleeve clamping screw and the base plate clamping screw.

When the utility model uses, at first the base plate in the utility model is fixedly installed on the oil pumping machine crank, and makes the sleeve that the ejection bolt is installed on the base plate face crank-pin to be torn open on the oil pumping machine crank by the crank pin hole on the sleeve clamping screw on the utility model, sleeve locking nut, sleeve clamping screw pad, base plate clamping screw, base plate locking nut, U bolt clamp and the oil pumping machine crank; Then with the ejection bolt on spanner rotation the utility model, withdraw among the crank pin hole of the front end that makes the ejection bolt on towards the disassembly direction throw crank pin of crank-pin from oil pumping machine crank; Because the utility model is by because of rotating the spiral motive force that produces crank-pin being disassembled on oil pumping machine crank between ejection bolt that is threaded mutually and the sleeve, so it is not only laborsaving, and efficient height, about 10 minutes consuming time of crank-pin of general dismounting, and only need two workman's operations to get final product.

The specific embodiment

The device that a kind of crank-pin that is used to dismantle on the oil pumping machine crank is used, it includes one and is set with a locking screw keyhole 10 and two free ends on it and has the base plate 8 of the sleeve 5 of internal thread, ejection bolt 4, sleeve clamping screw 2, sleeve locking nut 3, sleeve clamping screw pad 1, base plate clamping screw 6, base plate locking nut 7 and two U bolt clamps 9; Wherein ejection bolt 4 is threaded togather with sleeve 5; Sleeve clamping screw 2 and sleeve locking nut 3 are arranged on the sleeve 5 by sleeve clamping screw pad 1; The purpose that sleeve 5 is set is the projection that is used to hold crank-pin 14; Sleeve clamping screw pad 1 can provide a stressed platform for sleeve clamping screw 2 and sleeve locking nut 3 at the free end of sleeve 5; Base plate clamping screw 6 and base plate locking nut 7 are arranged on the base plate 8 by the locking screw keyhole 10 on the base plate 8; Two U bolt clamps 9 are connected to respectively on sleeve clamping screw 2 and the base plate clamping screw 6.

Owing to be subjected to the obstruction of the crank-pin assembly of installation on the crank-pin 14, the space in oil pumping machine crank 12 outsides is limited, can't be from its outside with among sleeve clamping screw 2 and the base plate clamping screw 6 insertion crank pin holes 13, so the utility model is fixed on the outside of oil pumping machine crank 12 with the rear end of U bolt clamp 9 with sleeve clamping screw 2 and base plate clamping screw 6 after adopting and from the inboard of oil pumping machine crank 12 sleeve clamping screw 2 and base plate clamping screw 6 being passed oil pumping machine crank 12 by crank pin hole 13 again.

When the utility model uses, at first the base plate in the utility model 8 is fixedly installed on the oil pumping machine crank 12, and makes the sleeve 5 that ejection bolt 4 is installed on the base plate 8 face crank-pin to be torn open on the oil pumping machine crank 12 14 by the crank pin hole 13 on the sleeve clamping screw 2 on the utility model, sleeve locking nut 3, sleeve clamping screw pad 1, base plate clamping screw 6, base plate locking nut 7, U bolt clamp 9 and the oil pumping machine crank 12; Then with the ejection bolt 4 on spanner rotation the utility model, withdraw among the crank pin hole 13 of the front end that makes ejection bolt 4 on towards the disassembly direction throw crank pin 14 of crank-pin 14 from oil pumping machine crank 12.

When the utility model uses, when all free crank pin hole 13 in the both sides of the crank-pin 14 of needs dismounting, preferably adopt occupation mode as shown in Figure 7, it is stressed the most even; When the free crank pin hole 13 of a side of the crank-pin 14 of needs dismountings, can adopt occupation mode as shown in Figure 9.

Labour intensity when using the utility model in order further to alleviate can also be set with a projection 11 at the front end of ejection bolt 4; Ejection bolt 4 reduces with the contact area of crank-pin 14 like this, thus the frictional force can reduce by 4 rotations of ejection bolt the time.
