The pin rods 63 are plugged into the limiting hole 301, and the front end of the pin rods 63 is fixedly installed with pin rods 64. The pin rods 64 pass through the through hole opened in the prying plate 3 and are plugged into the limiting hole 701.

[0029] It should be noted that: during transportation, the controller 9 controls the servo motor 4 to drive the shaft 31 to drive the skid plate 3 to rotate to a vertical state to complete the folding and contraction. When transported to the oil wellhead, the servo motor 4 is controlled to drive the shaft 31 to drive the skid plate 3 to rotate to a horizontal state, and then the oil production equipment is installed on the loading plate 7, and then the loading plate 7 is inserted into the plug-in slot 302, and then the electric rod 61 is controlled to drive the push plate 62 to move forward.

[0034] In the embodiments of the present invention, please refer to Figure 1 and Figure 7, both ends of the carrying frame 2 facing the skid plate 3 are fixedly installed with a pressing assembly 8, the pressing assembly 8 includes a guide rod 81 symmetrically installed at one end of the carrying frame 2, a lead screw 82 is rotatably installed between the two guide rods 81 on the carrying frame 2, a hand wheel 83 is fixedly installed on the top of the lead screw 82, an L-shaped pressing plate 84 is threadedly installed on the lead screw 82, and the pressure foot of the L-shaped pressing plate 84 is clamped with a groove on one side of the plug-in slot 302;

[0035] It should be noted that when the pressing assembly 8 is in use, after the skid plate 3 is folded, the hand wheel 83 is rotated to drive the lead screw 82 to rotate, thereby driving the L-shaped pressing plate 84 to move along the guide rod 81 until the pressing foot at the bottom end thereof is pressed into the insertion groove 302, thereby fixing the folded skid plate 3 and improving the folding stability;

[0036] In this embodiment, the outer wall of the hand wheel 83 is provided with anti-skid grooves, which increases the friction and facilitates the hand wheel 83 to be rotated by hand.

[0037] The working principle of the integral skid-mounted foldable wellhead platform provided by the utility model is as follows:

[0038] During transportation, the controller 9 controls the servo motor 4 to drive the shaft 31 to drive the skid plate 3 to rotate to a vertical state, and the hand wheel 83 is turned to drive the lead screw 82 to rotate, thereby driving the L-shaped pressing plate 84 to move along the guide rod 81 until the pressure foot at its bottom end is pressed and inserted into the insertion groove 302, thereby fixing the folded skid plate 3, improving the folding stability, and completing the folding and shrinking. When transported to the oil wellhead, the servo motor 4 is controlled to drive the shaft 31 to drive the skid plate 3 to rotate to a horizontal state, so as to facilitate the transportation of the skid plate 3. Use the support frame 5 to prop up the base plate 1, then install the oil production equipment on the loading plate 7, then insert the loading plate 7 into the insertion slot 302, and then control the electric rod 61 to drive the push plate 62 to move forward. During the movement, the driving pin rod 1 63 and the pin rod 2 64 are synchronously inserted into the limiting hole 1 301 and the limiting hole 2 701 respectively, so as to complete the limiting fixation of the skid plate 3 and the loading plate 7. When folding is required, control the electric rod 61 to retract until the pin rod 2 64 withdraws from the limiting hole 1 301.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
