Described carriage by an end be connected with described pin-and-hole, the other end and described chute do the pilot pin that is slidingly connected, an end fix connection, the other end of pilot pin is therewith formed with the pilot pin spring that described chute is abutted against mutually.
Described stopping means comprises the spacing card that an end is rotatably connected by bearing pin and described arc groove, the limit spring that the spacing therewith card of one end is abutted against mutually, the other end of this limit spring inserts in the described spacing hole, the other end of described spacing card is provided with and the corresponding inclined-plane of described flechette-type push rod head, and the middle part of this spacing card is provided with and the corresponding dop of described draw-in groove.
Characteristics of the present utility model are: this structure is the antisymmetry structure, and the employing chain replaces the mode of engagement respectively with reverse wheel and commutation piece, has reached to need not the purpose that the chain drive pumping unit shutdown just can commutate fast.And on the boss of commutation body, be provided with stopper slot, and chain is passed in this stopper slot, limited chain swinging when alternately meshing with reverse wheel and commutation piece, prevented that the phenomenon that chain and reverse wheel or commutation piece break away from from taking place.Guarantee the security of operation of chain drive pumping unit.
The utility model also has 1, easy to operate, need not shut down during the conversion direction of rotation; 2, conversion rate is fast, the efficient height; 3, simple in structure, cost of manufacture is low; 4, the characteristics of applied range.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Given embodiment further specifies the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the changement of a kind of chain drive pumping unit of the present utility model, comprise the orbit that pumping unit shelf is connected, the ballast box 10 that the chain 7 that is meshed with jockey sprocket is connected with chain 7 therewith, it is characterized in that this changement is a left and right sides antisymmetry structure, its left side structure is that the commutation piece 6 that the left side is provided with tooth bar is meshed with described chain 7, this commutation piece 6 is done with commutation body 8 and carriage and is slidingly connected, this commutation body 8 is provided with stopping means, on described orbit, be provided with reverse wheel 1, this reverse wheel 1 is meshed with described chain 7, one end of described commutation piece 6 opposite sides is provided with flechette-type push rod 12, its other end is provided with draw-in groove 2, the middle part of this commutation piece 6 is provided with, following two chutes 5, the top of described commutation body 8 is provided with boss 9, these boss 9 left ends are provided with stopper slot 11, described boss 9 right-hand members are provided with arc groove 13, the cambered surface of this arc groove 13 is provided with spacing hole 15, the middle part of described commutation body 8 and described chute 5 corresponding sections are arranged with pin-and-hole, described carriage and described commutation body 8 fix to be connected and to do with described chute 5 and are slidingly connected, described stopping means be located in the described arc groove 13 and with the clamping mutually of described draw-in groove 2, described chain 7 passes described stopper slot 11, the right side structure of described changement and left side structure antisymmetry.
