[0020] Two installation grooves 101 with bottom openings are formed on the left and right sides of the pumping unit base 1, and a moving wheel 3 is arranged in the installation groove 101, the wheel frame of the moving wheel 3 is vertically slidingly installed in the installation groove 101, and a vertical connecting rod 4 is fixed to the top of the wheel frame; the connecting rod 4 slidingly penetrates the top of the installation groove 101, and the upper end of the connecting rod 4 is fixedly connected with the lifting frame 5; the support frame 6 is fixed to the pumping unit base 1, and the first hydraulic cylinder 7 is vertically arranged, with the cylinder body end fixedly connected with the support frame 6 and the push rod end fixedly connected with the top of the lifting frame 5.

[0021] Horizontal support plates 8 are arranged on both sides of the foundation frame 2, and a first rack 9 is installed at the bottom of the support plate 8; C-shaped mounting frames 10 are fixedly connected on both sides of the lifting frame 5, and tooth blocks 11 adapted to the first rack 9 are arranged in the C-shaped mounting frames 10; when the wheel frame top of the moving wheel 3 contacts the top of the installation groove 101, the tooth blocks 11 engage with the first rack 9; when the moving wheel 3 contacts the foundation frame 2, the tooth blocks 11 are separated from the first rack 9.

[0022] More specifically, the support frame 6 is in the shape of a door, and the foundation frame 2 is embedded with guide rails 17 adapted to the moving wheel 3.

[0023] Initially, the wheel frame top of the moving wheel 3 contacts the top of the installation groove 101, the tooth blocks 11 of the C-shaped mounting frame 10 engage with the first rack 9, and the pumping unit base 1 falls on the foundation frame 2; when moving, first, the first hydraulic cylinder 7 is started, the push rod of which is extended to drive the four moving wheels 3 to move downward through the lifting frame 5, and when the moving wheels 3 contact the foundation frame 2, the tooth blocks 11 are separated from the first rack 9; the push rod of the first hydraulic cylinder 7 is continuously extended to separate the pumping unit base 1 from the foundation frame 2. Subsequently, the driving assembly is actuated to drive the pumping unit base 1 to move back and forth along the guide rails 17 through the moving wheels 3; after reaching the position, the push rod of the first hydraulic cylinder 7 is retracted to drive the pumping unit base 1 and the moving wheels 3 to reset, and the tooth blocks 11 of the C-shaped mounting frame 10 re-engage with the first rack 9, thereby locking the pumping unit base 1 and the foundation frame 2 into one body, avoiding the pumping unit base 1 from moving back and forth due to external force. Embodiment two

[0024] As a preferred embodiment of the present application, the driving assembly is designed based on the embodiment one, specifically:

[0025] With reference to Figure 1As shown, a second rack 12 is mounted on the base frame 2, which is parallel to the first rack 9. The drive assembly includes a second hydraulic cylinder 13, a swing arm 14, a motor 15, and a gear 16 adapted to the second rack 12.
