The utility model is in order to overcome deficiency of the prior art, and a kind of pumping unit sliding type stroke regulating mechanism of simple in structure, easy to operate, high working efficiency is provided.
The utility model is achieved through the following technical solutions:
A kind of pumping unit sliding type stroke regulating mechanism, comprise crank, described crank is provided with output shaft hole, the both sides of described crank are respectively arranged with balancer weight and adjust slideway, it is characterized in that, described crank center is provided with slideway, and crankshaft places in the described slideway with slide block composition gliding mass, and described slide block is fixed on the crank by hold-down bolt or hold-down bolt and pressing plate.
The cross section of described slideway is T type or I shape.
The end of described crank is provided with the guide plate that has internal thread, have that externally threaded guide rod passes described guide plate, slideway is connected with described slide block, both sides with the guide rod relevant position on the described slide block are respectively arranged with pin hole, be provided with cotter slot with the corresponding position of pin hole on the described guide rod, pin inserts in pin hole, the cotter slot slide block and guide rod is fixed.
The cross section of described pressing plate or hold-down bolt is the T type.
The utlity model has following technique effect:
The utility model is adjusted the position of crankshaft by slide type, thereby adjusts the stroke of pumping unit, and is simple in structure, do not need to use crane to cooperate, easy to operate, the time and labour saving, reduce working strength of workers, improved the Security of operation, improved working efficiency simultaneously.
