Problems solved by technology

[0004] The purpose of the present invention is to provide a drilling floor manipulator lifting mechanism capable of driving the drilling floor in view of the problems in the prior art that the drilling floor manipulator needs to occupy the catwalk operation area on the drilling floor surface, resulting in low drilling efficiency and increased drilling costs. The manipulator is raised and lowered to avoid the catwalk operation area

Embodiment 1

[0045] Such as Figure 5 As shown, a lifting mechanism for a drill floor manipulator described in this embodiment includes a frame body 8, a manipulator mounting base 3, a telescopic device 4 and a steel wire rope 5, and the manipulator mounting base 3 is used for installing a drill floor manipulator. The frame body 8 is vertically slidably matched with the manipulator mounting base 3, the frame body 8 is provided with a fixed pulley block 7 and a movable pulley block 6, the fixed pulley block 7 is located on the top of the frame body 8, and the telescopic One end of the device 4 is connected to the lower part of the frame body 8, the other end is connected to the movable pulley block 6, one end of the steel wire rope 5 is connected to the manipulator mounting base 3, and the other end bypasses the fixed pulley block in turn 7 and the moving pulley block 6 are then connected to the frame body 8, the telescopic device 4 is located under the moving pulley block 6, and when the m...

Embodiment 2

[0056] Such as Figure 1-3 As shown, the lifting mechanism for the drill floor manipulator described in this embodiment differs from Embodiment 1 in that in order to further reduce the height of the frame body 8 and reduce the space occupied by the frame body 8, the The frame body 8 includes a fixed rail frame 1 and a telescopic frame 2, the fixed rail frame 1 and the manipulator mounting seat 3 are vertically slidably matched with the telescopic frame 2, and the fixed pulley block 7 is arranged on the fixed rail frame 1 The upper part of the telescopic device 4 is connected with the lower part of the fixed guide rail frame 1 .

[0057] On the basis of the above, in a further preferred manner, there are at least two second guide rails 24, all of the second guide rails 24 are arranged in parallel, and at least two of the second guide rails 24 are arranged diagonally.

[0058] On the basis of the above, in a further preferred manner, there are four guide rails 24, and the adjac...

Embodiment 3

[0069] Such as Figure 4 As shown, the lifting mechanism for a drill floor manipulator described in this embodiment is different from Embodiment 2 in that: the telescopic frame 2 includes at least two telescopic units 25 that are sequentially nested and arranged adjacent to each other. The telescopic units 25 are vertically slidably matched with each other, the outermost telescopic unit 25 is vertically slidably fitted with the fixed guide rail frame 1, and the innermost telescopic unit 25 is vertically slid with the manipulator mounting base 3 Cooperate.

[0070] The telescopic frame 2 includes at least two telescopic units 25 that are sequentially nested and arranged. Through the relative sliding between adjacent telescopic units 25, the overall height of the frame body 8 after contraction can be reduced under the same lifting height of the manipulator mounting base 3 Smaller, more compact and takes up less space.

[0071] Now, the labor-saving pulley on the movable pulley...

Abstract

The invention relates to the field of petroleum machinery, in particular to a lifting mechanism for a drill floor manipulator. The drill floor manipulator comprises a manipulator mounting seat; a frame body which is in vertical sliding fit with the manipulator mounting seat; fixed pulley blocks arranged at the upper part of the frame body; movable pulley blocks; telescopic devices, wherein one ends of the telescopic devices are connected with the lower portion of the frame body, the other ends of the telescopic devices are connected with the movable pulley blocks, the telescopic devices can drive the movable pulley blocks to move and are located on the sides, away from the fixed pulley blocks, of the movable pulley blocks; and steel wire ropes, wherein one ends of the steel wire ropes are connected with the manipulator mounting seat, and the other ends of the steel wire ropes sequentially pass the fixed pulley blocks and the movable pulley blocks and then are connected with the frame body. According to the lifting mechanism for the drill floor manipulator, ascending and descending of the manipulator mounting seat can be effectively achieved, and therefore the purpose of avoiding a catway operation area is achieved.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a lifting mechanism for a drill floor manipulator. Background technique [0002] Drill floor manipulator is an important machine to realize the transfer of drilling tools. During the operation, the drill floor manipulator controls the movement track of the lower end of the drilling tool to prevent safety accidents. The manipulator on the drilling floor needs to occupy the operation area of ​​the catwalk on the drilling floor, resulting in low drilling efficiency and increased drilling costs. [0003] Therefore need a kind of drill floor manipulator lifting mechanism, can drive the drill floor manipulator lifting, make when catwalk normal operation, can sink the drill floor manipulator from the drill floor surface to the drill floor surface. Contents of the invention [0004] The object of the present invention is to provide a drilling floor manipulator lifting mechanism capa...
