[0025] The supporting drilling rig base includes a skid plate 1, a base body 3, combined support legs 2, and a working ladder 4 (see the instruction manual). Figure 1 and 2 ).

[0026] The base body 3 is surrounded by a railing 20. The base body 3 is mounted on the skid plate 1 via multiple sets of combined support legs 2 (see instruction manual). Figure 1 ).

[0027] The combined support leg 2 includes a column 24, a connecting pin 27, an intermediate sleeve 25, and an upper sleeve 23 (see the instruction manual appendix). Figure 1 and 3 The base body 3 is symmetrically equipped with multiple upper sleeves 23; the skid plate 1 is symmetrically equipped with multiple columns 24; intermediate sleeves 25 are fitted onto the columns 24; multiple insertion holes 26 are provided at intervals on both the intermediate sleeves 25 and the columns 24; the intermediate sleeves 25 and the columns 24 are fixedly connected through the insertion holes 26 and connecting pins 27; the upper sleeves 23 are inserted into the corresponding intermediate sleeves 25; the lower end of the upper sleeves 23 is provided with locking holes 28; the upper sleeves 23 are fixedly connected to the intermediate sleeves 25 through the locking holes 28, the corresponding insertion holes 26, and the connecting pins 27 (see the appendix of the instruction manual). Figure 3 ).

[0028] The purpose of this combination of support legs 2 is that, after the intermediate sleeve 25 and the column 24 are inserted, the overall height of the intermediate sleeve 25 and the column 24 can be adjusted via the connecting pin 27 to suit the needs of various working heights. When the supporting drilling rig base is not in operation, the intermediate sleeve 25 and the column 24 are in a retracted state to save space. When the supporting drilling rig base is in operation, the intermediate sleeve 25 and the column 24 are in an extended state, thus allowing the base body 3 to be installed at a higher position to meet production needs.

[0029] A working ladder 4 is installed on one side of the base body 3 (see instruction manual). Figure 2 The working ladder 4 includes an upper ladder 29, a lower ladder 22, and a limiting claw 30 (see the instruction manual appendix). Figure 8 ).

[0030] A ladder 29 is mounted on one side of the base body 3 via a pivot 8 (see instruction manual). Figure 8 The lower end of the upper ladder 29 is symmetrically fixed with "L"-shaped limiting claws 30 on both sides (see instruction manual). Figure 8 , 9 (and 10). A sliding channel 31 is formed between the limiting claw 30 and the upper ladder 29; guide angle irons 32 are fixed on both sides of the lower ladder 22; the lower ladder 22 is connected to the upper ladder 29 through the guide angle irons 32 and the sliding channel 31. During operation, the lower ladder 22 can slide along the upper ladder 29 with the cooperation of the sliding channel 31 and the guide angle irons 32. In the non-operating state, the lower ladder 22 can maintain an overlapping state with the upper ladder 29 under the action of friction; when in the operating state, the lower ladder 22 is pulled down, causing it to slide out of the lower ladder 29 and its bottom to contact the ground, thus presenting the operating state.

[0031] An escape slide 5 is installed on the other side of the base body 3 (see instruction manual). Figure 2 The escape slide 5 includes a lower slide 6 and an upper slide 7 (see instruction manual attached). Figure 4-7 ).

[0032] An upper slide body 7 is mounted on the base body 3 via a pivot 8. The upper slide body 7 includes an upper slide plate 10, a support plate 13, side beams 12, and safety sleeves 17. Two sets of connecting lugs 11 are symmetrically mounted on the upper end of the upper slide plate 10. The connecting lugs 11 are connected to the base body 3 via the pivot 8. Side beams 12 are symmetrically welded to both sides of the upper slide plate 10. A support plate 13 is welded to the lower end of the side beams 12. A cavity 14 is formed between the support plate 13 and the upper slide plate 10. A positioning hole A15 is provided at the lower part of the side beams 12. Safety sleeves 17 are mounted on both sides of the upper slide plate 10 via limiting rods 16 (see the attached instruction manual). Figure 4 and 7 ).

[0033] A lower slide plate 6 is slidably mounted inside the upper slide body 7; the lower slide plate 6 is also slidably mounted inside the receiving cavity 14; a roller 18 is mounted on the upper end of the lower slide plate 6; multiple positioning holes B19 are provided at intervals in the middle of the lower slide plate 6; a pin 9 is inserted between the positioning hole A15 and the corresponding positioning hole B19. The purpose of this escape slide 5 is to allow the lower slide plate 6 to be pulled out from the receiving cavity 14 of the upper slide body 7 to a suitable position after the pin 9 is pulled out during operation, and then the pin 9 is inserted between the positioning hole A15 and the corresponding positioning hole B19, thus achieving the purpose of reconnecting the lower slide plate 6 to the upper slide body 7.

[0034] Safety pins 21 are symmetrically arranged on the lower slide plate 6; the safety pins 21 are plugged into the corresponding safety sleeves 17 (see the instruction manual appendix). Figure 4 and 5 The purpose of setting the safety plug 21 in this way is to keep the safety plug 21 and the safety sleeve 17 in a movable connection, so that the lower slide plate 6 can move smoothly relative to the upper slide body 7, and during operation, the safety plug 21 and the safety sleeve 17 can provide safety for the escape slide 5, avoiding the problem of the escape personnel sliding out of the escape slide 5 during the escape.

[0035] This supporting drilling rig base, through the telescopic design of the combined outriggers 2, working ladder 4 and escape slide 5, can not only meet the construction and transportation needs at different heights, but also solve the problem of high safety hazards caused by the lack of escape channels in existing bases, making it particularly suitable for the requirements of oil drilling and production.
