DETAILED DESCRIPTION

[0022] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, the present invention provides a front-mounted oil pumping unit using a reducer and a motor as a counterweight, including a base 16 and a power base 13;

[0024] The base 16 is fixedly connected with a bracket 8; the top of the bracket 8 is connected to one end of a walking beam 4 through a middle seat 7, the other end of the walking beam 4 is connected to a donkey head 3, the donkey head 3 is connected to a drooping steel wire rope 2, and a rope hanger 1 is provided on the steel wire rope 2;

[0025] The middle part of the walking beam 4 is connected to one end of a single connecting rod 6 through a bearing seat;

[0026] The power base 13 is located above the base 16, and is fixed to the base through a support seat and a bearing seat; the height of the bracket is higher than the height of the power base;

[0027] The other end of the single connecting rod 6 is hinged to one end of the power base 13;

[0028] A reducer 11 and a motor 9 are fixedly connected to a side of the power base 13 away from the single connecting rod. A pulley is provided on the reducer 11, and a belt 10 on the pulley is in transmission connection with the motor 9.

[0029] The first crank 12 and the second crank are respectively provided on both sides of the reducer 11. The first crank 12 is hinged to one end of the first connecting rod 14, and the other end of the first connecting rod 14 is hinged to the base 16; the second crank is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the base 16. The first connecting rod 14 and the second connecting rod are respectively located on both sides of the power base 13;

[0030] The power base 13 is in the shape of an elongated strip.

[0031] The other end of the single connecting rod is hinged to one end of the power base through a bearing seat.

[0032] In this embodiment, the reducer 11 and the motor 9 are arranged on one side of the power base, so that the weight of the reducer 11 and the motor 9 is applied to the balance of the pumping unit, which simplifies the structure of the pumping unit to the greatest extent. The rocker mechanism composed of the walking beam 4, the donkey head 3, the bracket 8, and the single connecting rod 6, and the reducer 11, the motor 9, and the power base 13 form a power mechanism. With the support seat 17 as the support point, the power can be transmitted to the walking beam and the donkey head in the rocker mechanism through the swing of the power base, so that the donkey head can reciprocate.

[0033] Specifically, the first crank 12 in this embodiment is hinged to one end of the first connecting rod 14 through the crank pin 15, and the other end of the first connecting rod 14 is hinged to the base 16 through the crank pin 15;

[0034] The second crank is hinged to one end of the second connecting rod through a crank pin, and the other end of the second connecting rod is hinged to the base through the crank pin.

[0035] The support base 17 in this embodiment plays the role of a lever support point for the power base and is located at the middle position of the power base. The middle position is not limited to being just the midpoint position, but can be a middle position that is biased towards the side of the single connecting rod.

[0036] In actual application, the rocker 4, the donkey head 3, the bracket 8, and the single connecting rod 6 are hinged to form a whole, forming a rocker structure. The rocker structure is hinged to one end of the power machine base 13 through the bearing seat 5, and the other end of the power machine base 13 is connected to the reducer 11 and the motor 9, and the other end is connected to the rocker structure composed of the rocker, the donkey head, the bracket, and the single connecting rod, with the support seat 17 as the fulcrum, so that the power base acts as a lever to swing up and down. The crank 12 of the reducer 11 is hinged to the base 16 through the connecting rod, and the motor 9 drives the reducer 11 as the power part through the belt 10, so that the power base 13 performs up and down reciprocating rocker motion.

[0037] When the motor 9 rotates, the reducer 11 can be driven by the belt 10 to rotate the first crank and the second crank, the first crank drives the first connecting rod to move, and the second crank drives the second connecting rod to move. Since the base is fixed and the first connecting rod and the second connecting rod are located on both sides of the power base, the power base 13 performs a swing rod movement based on the reaction principle. The power is transmitted to the swing rod mechanism composed of the rocker, the donkey head, and the bracket through the single connecting rod 6, so that the donkey head 3 performs up and down reciprocating motion, thereby driving the wire rope 2 to perform up and down reciprocating motion, and finally realizing the oil production function.

[0038] The present invention provides a front-mounted oil pumping unit that uses a reducer and a motor as a counterweight, applies the weight of the reducer and the motor to the balance of the oil pumping unit, uses the motor as a power source, and transmits power to a rocker arm mechanism composed of a walking beam, a donkey head, a bracket, and a single connecting rod through a power mechanism composed of the reducer, the motor, and a power base, ultimately causing the donkey head to reciprocate up and down to realize the oil pumping function, thereby simplifying the traditional complex structure of the oil pumping unit to the greatest extent, reducing energy cost consumption, and achieving the purpose of energy saving and environmental protection.

[0039] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
