[0013] Beneficial effects: 1) By adopting the cross beam and the concave-shaped transmission bracket as the moving track, it is convenient for the driving rollers to slide back and forth along the cross beam. The hinged connection of the angle adjusting roller shaft and the movable hinge shaft changes the inclination angle position of the connecting rod. The angles of the components used for construction placement and reinforcement are more flexible and variable, adapting to the ground oil ports with different slopes and heights. After the pneumatic cylinder expands and contracts, the height of the connecting rod is replaced, and the well-matched trapezoidal bearing frame improves the height of the movable sleeve rod, making the construction position of the robotic arm more flexible and accurately aligned with the construction oil port, placing and reinforcing the materials of the oil well in the oil field. The coordinated operation of multiple mechanisms greatly improves the transformation efficiency of the oil field port and quickly resumes the exploitation work of the waste oil port; 2) The sliding rollers adopted can move linearly along the connecting strut. Combined with the arc-shaped guiding bracket, as long as the cylinder body of the pneumatic cylinder is controlled to expand and contract, the change in the construction direction of the connecting rod can be coordinated, and the alignment with the oil port position is more flexible and variable, adapting to oil ports with different depths. Placing the arc-shaped gasket into the oil inlet is more accurate and convenient, reducing the construction pressure. One end of the arc-shaped hinged bracket is hinged to the connecting rod. At this time, according to the position of the clinical oil port, the construction machinery is gradually adjusted in angle to align with the oil field port and the construction position of the oil field holding and stopping well. The depth at which the arc-shaped gasket is placed and pasted on the inner wall of the oil port is adjustable, avoiding manual pasting of the reinforcement material on the inner wall of the oil field port; 3) Based on the support of the articulated roller shaft and multiple "J" brackets, one end of the transmission roller shaft is connected. In terms of reinforcement, according to the multiple angle changes of the coordination rod, the position of the trapezoidal bracket is changed, and the trapezoidal bracket is gradually pushed and changed. After being clamped by the clamp, the arc gasket is distributed and probed. As the position of the active joint, the position of the push rod is moved by changing the angle of the active joint. According to the movement of the push rod body, the arc gasket for reinforcing the inner wall is posted. The magnetic adsorption and the mechanical arm structure used for posting cooperate with each other. In terms of construction, it is easier to support and stop the well of the oil field to be reinforced with the arc gasket, avoiding manual posting of the arc gasket. In the reinforcement stage, the pouring tank is used to cooperate, so that the construction party can deal with it more calmly. In addition, the bottom angle of the heavy arc gasket fits, and the concave traction bracket and the U-shaped binding rod can be used to cooperate with each other to change the position below the arc gasket. When posting, it moves synchronously with the arc gasket to the inner wall of the oil field mouth. 4) After the driving motor is powered on, it drives the drilling auger to rotate, and the height of the auger head is adjusted by using the articulation of the articulated roller shaft. The articulated support of the arc-shaped connecting bracket and the spraying of the water pipe and the sprinkler head are adopted to ensure that the atomized water vapor is sprayed out from the position of the sprinkler head to suppress the diffusion of dust. Combined with the concrete storage tank and the extraction pump, the concrete material is extracted from the concrete storage tank after power is turned on and sprayed out from the inclined water outlet pipe end. The purpose is to eliminate the magnetic force. At the same time, it is more convenient to post the arc-shaped steel plate on the inner wall of the oil well. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] On the side of the outer frame 51, there is also a pushing mechanism 8. The pushing mechanism 8 includes a movable joint 81 installed on the side wall of the outer frame 51. At the end of the movable joint 81, a rotating rod 82 is installed. At the bottom end of the rotating rod 82, a transmission base 83 is installed. At the bottom end of the transmission base 83, there is a gooseneck tube 84. At one end of the gooseneck tube 84, an auxiliary mounting plate 85 is installed.

Through the hinge of the coordination rod 76, it approaches according to the push of the trapezoidal bracket 77. Based on the hinge at one end of the coordination rod 76, clamping is achieved according to the push state of the trapezoidal bracket 77. Approach the corresponding coordination rod 76 on both sides of the toggle clamp 79, and gradually change its moving direction, thereby changing the orientation of the trapezoidal bracket 77. According to the push at one end of the toggle lever 792, gradually push according to the push rod 791, change the position of one end of the trapezoidal bracket 77, and the hinged toggle clamp 79 gradually clamps and holds the two sides of the arc-shaped gasket 541; According to the extension movement of the push rod 87, then use the auxiliary installation plate 85 to push to make the position of the oilfield support and stop wellbore move back and forth. According to the push of the push rod 87, gradually ensure the auxiliary installation plate 85. According to the hinge of the adjusting roller shaft 86, and then use the gooseneck tube 84 to hinge to realize the flexible angle change of the adjusting roller shaft 86. Manually control the push rod 87 to gradually push the arc-shaped gaskets 541 in different areas to fit with the inner wall of the wellhead; Use one end of the spherical movable ball 56 to gradually and slowly adjust the position of the concave traction bracket 59. Based on the position of the concave traction bracket 59, it is attached to the inner wall of the oilfield support and stop well. The position of the arc surface of the arc-shaped gasket 541 is attached to the inner wall of the well body, and it remains at a certain fitting angle with the inner wall of the wellhead, which is convenient for pouring concrete.
