Belt shield and belt replacing all-in-one machine method and device

Abstract

The invention relates to the technical field of pumping units, in particular to a belt shield and belt replacing all-in-one machine method and device which are low in cost, high in universality and simple to operate. A long support 3, a fixed upper support 31, a fixed lower support 5 and a short support 35 form a fixed frame which can be used as a ladder, one person does not need to climb up a reduction gearbox when adding a belt 1, operation is safe, the belt 1 can be tightened when a pumping unit runs, and the belt 1 reaches the designed life during operation. According to the method, a belt 1 replacing device and a belt shield device are integrated into an all-in-one machine, so that the functions of the belt 1 replacing device and the functions of the belt shield device are not affected mutually, the service life of the belt 1 meets the requirement, a belt shield is improved to be an internal fixing method from an outer wrapping method, and the protection capacity of the belt shield is enhanced.

Description

technical field [0001] The invention relates to a method and a device for an integrated machine for replacing a belt guard and a belt in the technical field of pumping units. Background technique [0002] The belt guard devices of various beam pumping units are various, and the belt changing devices of various beam pumping units are various. The two accessories of one pumping unit develop independently, and develop into two irrelevant technical systems , These two systems develop independently and the cost continues to rise. In the case of changing the belt device, the purpose is to move the motor forward by 20 cm and then move it back by 20 cm. It does not take too long and does not require much labor intensity. , The motor directly threatens the life safety of the belt changing operator when it rains. There are various motor belt guard devices, none of which are considered to be used in conjunction with the belt changing device, resulting in the installation of the belt gu...

[0002] The belt guard devices of various beam pumping units are various, and the belt changing devices of various beam pumping units are various. The two accessories of one pumping unit develop independently, and develop into two irrelevant technical systems , These two systems develop independently and the cost continues to rise. In the case of changing the belt device, the purpose is to move the motor forward by 20 cm and then move it back by 20 cm. It does not take too long and does not require much labor intensity. , The motor directly threatens the life safety of the belt changing operator when it rains. There are various motor belt guard devices, none of which are considered to be used in conjunction with the belt changing device, resulting in the installation of the belt guard device for beam pumping units in oilfields across the country. Only one of the belt devices can be installed. The belt replacement devices installed nationwide now say that one person can change the belt, but in reality, one person cannot change the belt without climbing on the gearbox. It is illegal to climb on the gearbox in rainy days.
