[0018] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0019] Example 1

[0020] The mud protection device of the pipe supporting manipulator of the utility model has a structure as follows Figure 1 and Figure 2 As shown, it includes a traveling track 5, on which a traveling pulley 3 is arranged, and a roller 11 is installed at the bottom of the traveling pulley 3. The traveling pulley 3 moves along the track on the traveling track 5 through the roller 11. A mechanical arm assembly 2 is installed on the top of the traveling pulley 3, and a supporting clamp 1 is connected to the end of the mechanical arm assembly 2 away from the traveling pulley 3; protective mechanisms are arranged at the positions where the middle parts of both sides of the traveling pulley 3 contact the traveling track 5 to prevent mud from entering the inside of the track from the gap between the traveling pulley 3 and the track; the offset pulley 4 runs on the offset track 6, and the offset track 6 is orthogonal to the traveling track 5; the mechanical arm assembly 2 runs between the offset pulley 4 and the traveling track 5 through the traveling pulley 3, and the electric control system 7 controls the movement trajectory of the offset pulley 4 and the traveling pulley 3.

[0021] Example 2

[0022] The difference from Example 1 is that

[0023] like Figure 3 and Figure 4 As shown, the protection mechanism includes a protection plate 8, a clamping plate 9 and a bolt 10; the protection plate 8 is clamped by two clamping plates 9 and fastened to the middle of both sides of the walking pulley 3 by bolts 10, and the two clamping plates 9 serve as retaining frames for the protection plate 8, and the rubber protection plate 8 is mounted on the walking pulley 3 of the pipe-supporting manipulator through the retaining frames. During the drilling process, the pipe-supporting manipulator walks and works at the wellhead of the drilling platform. The rubber protection plate 8 has a certain strength through the clamping of the clamping plates 9, and the rubber plate itself has a certain toughness, which can effectively protect the mud on the walking track, and is not prone to shutdown, avoiding the risk of mud falling onto the track and causing jamming or damage to the motor, reducing failures and downtime, and ensuring the normal operation of the pipe-supporting manipulator.

[0024] The protective plate 8 is a rubber protective plate, which is a consumable product. It is easy to remove from the clamping plate 9 after being worn, and is easy to replace on site. When the rubber protective plate 8 encounters a height difference at the track joint, it can bend and pass through, which enhances the passability of the protective plate; the clamping plate 9 is a steel plate, which keeps the protective plate 8 strong while keeping the rubber protective plate not easy to break, increasing the mud protection effect, and can effectively protect the mud on the track of the pipe support manipulator, and reduce the risk of downtime.

[0025] Example 3

[0026] The specific working process of the mud protection device of the pipe supporting manipulator of the utility model is as follows:

[0027] like Figure 1 and Figure 4 As shown, the supporting clamp 1 is installed on the mechanical arm assembly 2, and the mechanical arm assembly 2 can switch between the walking track 5 and the offset track 6 through the walking pulley 3; the protective plate 8 is clamped by two clamping plates 9 and fastened to the middle part of the walking pulley 3 by bolts 10.

[0028] When not in operation, the traveling block 3 and the mechanical arm assembly 2 on it stay on the offset block 4, and the initial position is at the left end of the offset track 6. When in operation, the electric control system 7 issues a command, and the offset block 4 drives its upper parts (traveling block 3, mechanical arm assembly 2, supporting clamp 1, etc.) to run from left to right on the offset track 6. When the running is flush with the position of the traveling track 5, the offset block 4 stops moving. The traveling block 3 and its upper parts (mechanical arm assembly 2, supporting clamp 1, etc.) are driven by the traveling block 3 to reach the set position of the wellhead of the drilling platform from the outside to the inside on the traveling track 5. During the operation of the traveling block 3, the protective plate 8 installed in the middle of the traveling block 3 can effectively protect the mud spilled from the wellhead onto the traveling track 5.

[0029] On the contrary, it is the process of the pipe-supporting manipulator running from the wellhead to the non-working position; the control system issues a command, and the walking pulley 3 and its upper parts are driven by the walking pulley 3 to run from the wellhead to the outside on the walking track 5; when the walking pulley 3 and its upper parts run to the offset pulley 4 at the end, the offset pulley 4 drives its upper parts to run from right to left on the offset track 6 until it reaches the left end of the offset track 6.

[0030] The mud protection device of the pipe-supporting manipulator of the utility model has the following advantages: the rubber protection plate is clamped by the steel clamping plate and is not easy to break, but can be bent to pass through, thereby enhancing the passability of the protection plate; the mud on the track of the pipe-supporting manipulator is effectively protected to prevent the mud from entering the track from the gap between the walking pulley and the track, to avoid the track being blocked to cause a stop or damage the motor to affect the operation of the system, to reduce failures, to have reliable quality, to have good operating effect, and to meet the on-site HSE requirements.
