DETAILED DESCRIPTION

[0024] The high support device of the petroleum drilling machine includes base 1, winch 11, steel wire rope, support sliding sleeve 2, moving sliding rod 4, upper cross rod 3, lower cross rod 5, support cross plate 6 and gasket 7 (see the description accompanying drawings Figure 1 and2 ).

[0025] The base 1 is symmetrically fixed with support sliding sleeve 2 (see the description of the attached Figure 1 and 2 ). The two sides of the support sliding sleeve 2 are connected with the base 1 through the inclined pull rod 18 (see the description of the attached Figure 1 and 2 ). The inclined pull rod 18 has the purpose of strengthening the support strength of the support sliding sleeve 2.

[0026] The inner side of the support sliding sleeve 2 is provided with an open sliding groove 17 (see the description of the attached Figure 7 ). The lower cross bar 5 can slide up and down along the open sliding groove 17 during work.

[0027] The top of the support sliding sleeve 2 is fixed with the upper cross bar 3 (see the description of the attached Figure 1 and 2 ). The moving sliding rod 4 is slidingly installed in the support sliding sleeve 2 (see the description of the attached Figure 1 and 2 ). The moving sliding rod 4 can slide up and down in the support sliding sleeve 2 when subjected to force.

[0028] The lower end of the moving sliding rod 4 is fixed with the lower cross bar 5 (see the description of the attached Figure 1 , 2 , 6 and 7). The upper end of the moving sliding rod 4 is fixed with the support horizontal plate 6; the support horizontal plate 6 is fixed with the cushion plate 7.

[0029] The two ends of the support horizontal plate 6 are provided with limiting protrusions 15 (see the description of the attached Figure 1 and 2 ). The limiting protrusions 15 have the function of limiting;

[0030] The cushion plate 7 is made of polyurethane rubber material; the inner side of the cushion plate 7 is symmetrically provided with two groups of positioning grooves 16 (see the description of the attached Figure 5 ). When assembled, the cushion plate 7 can be positioned and installed on the support horizontal plate 6 through the positioning grooves 16; after the cushion plate 7 is placed on the support horizontal plate 6, it can be fixed through the hoop (not shown in the attached drawings).

[0031] The lower end surface of the upper cross bar 3 is provided with a fixed pulley 8 and a lifting lug 9; the upper end surface of the lower cross bar 5 is fixed with a movable pulley 10; the base 1 is provided with a winch 11; one end of the steel wire rope on the winch 11 is connected with the lifting lug 9 after passing through the fixed pulley 8 and the movable pulley 10 in sequence (see the description of the attached Figure 4 ).

[0032] The purpose of the arrangement is to enable the winding machine 11 to drive the moving slide 4, the support horizontal plate 6 and the pad 7 to move upward through the wire rope, the fixed pulley 8, the movable pulley 10 and the hanger 9 and the lower cross bar 5 when the winding machine 11 rotates to wind the wire rope; and to enable the support horizontal plate 6 and the pad 7 to move downward gradually under the action of gravity when the winding machine 11 rotates to unwind the wire rope.

[0033] One side of the upper cross bar 3 is fixed with a lower ladder 12; one side of the support horizontal plate 6 is fixed with an upper ladder 13; the lower ladder 12 is provided with a guide sliding groove 14; the upper ladder 13 is slidably connected with the lower ladder 12 through the guide sliding groove 14 (see the attached drawings) Figure 1 and 6 ).

[0034] A plurality of locking screws (not shown in the attached drawings) are threadedly connected to the support sliding sleeve 2; the locking screws are slidably connected with the moving slide 4. The purpose of the arrangement is to enable the moving slide 4 to be fixed with the support sliding sleeve 2 by tightening the locking screws when the moving slide 4 is moved to a proper position, thereby avoiding the occurrence of a safety accident due to the sliding between the moving slide 4 and the support sliding sleeve 2 when the wire rope suddenly breaks. When it is necessary to adjust the position of the moving slide 4, the locking screws are loosened.

[0035] When the high support device of the oil drilling rig is used, the locking screws are loosened, and then the winding machine 11 is started to rotate to wind the wire rope. The winding machine 11 can drive the moving slide 4, the support horizontal plate 6 and the pad 7 to move upward through the wire rope, the fixed pulley 8, the movable pulley 10, the hanger 9 and the lower cross bar 5. When the pad 7 is moved to a proper position, the winding machine 11 is stopped, and then the locking screws are tightened.

[0036] When the high support device of the oil drilling rig needs to be transported after the work is completed, the locking screws are loosened, and then the winding machine 11 is started to rotate to unwind the wire rope. The winding machine 11 can drive the moving slide 4, the support horizontal plate 6 and the pad 7 to move downward through the wire rope, the fixed pulley 8, the movable pulley 10, the hanger 9 and the lower cross bar 5. When the moving slide 4 is moved to the bottom end, the locking screws are tightened to keep the high support device in a retracted state. Then the high support device of the oil drilling rig is moved to the next work section for continuous use.

[0037] The high support device of the oil drilling rig has a compact structure and a clever design, and is controlled to be expanded and retracted by the winding machine 11, thereby solving the problems of inconvenience and high safety risk of the existing high support device, and is particularly suitable for use with the oil drilling rig.
