Embodiment 1

[0040] Furthermore, the walking device 1 includes two crawler belts 18, two motors 25 and two driving wheels 19, and realizes the walking and turning actions of the disassembly robot through differential drive.

[0041] Example 5

[0042] Furthermore, the load-bearing wheel 20 is made of high-strength manganese steel above 40Mn2; the driving wheel 19 and guide wheel 22 are made of ZGSiMn alloy steel, and the supporting sprocket is made of high-strength manganese steel above 50Mn , The shaft parts are made of 45# steel or 40Cr alloy steel or above, modulated and blackened.

Embodiment 2

[0046] Wherein, the mechanical arm assembly 5 is installed on the front end of the crawler chassis 2 to facilitate the forward detection operation of the mechanical arm, and the mechanical arm can be folded and stowed for easy transportation.

[0047] Further, the main control box 3 is connected with the walking device 1, the manipulator control box 4, the remote control terminal 6, the inverter 16, the infrared pan-tilt camera 11, the visible light camera 12, the gas detector 13, and the temperature sensor 14 respectively. It is controlled and connected with the storage battery 8, and the storage battery 8 supplies power to all electrical appliances through the main control box 3. In addition, the inverter 16 converts the direct current into the alternating current required by the manipulator assembly 5. In this embodiment, the peak power of the manipulator assembly 5 is 13.5KVA when it is fully loaded, the input voltage is 380V, and the power of the drive motor 25 is 6kW. Sin...

Embodiment 3

[0049] Further, the distal end of the mechanical arm assembly 5 is connected to a clamping device 9, and the other end of the clamping device 9 is connected to a tool head 10, and the tool head 10 is a C-shaped fastening mechanism 17, a breaking hammer, a hydraulic saw, a clamp One of them, the C-shaped fastening mechanism 17 is preferably a C-shaped mechanical locking structure, refer to Figure 5 , there is no need to increase the electric control or air control mechanism, because the failure rate of the air control or electric control device in the high temperature and water flow environment is high in the blowout out of control fire environment, which is easy to affect the normal operation, and the operation tools are damaged during the operation. Impact, long-term operation without mechanical locking will easily lead to changes in the position of the working tools, which will affect the precision control of remote control operations.

[0050] The clamping device 9 include...

Abstract

The invention discloses a wellhead dismounting and mounting robot used after oil and gas well blowout out-of-control fire and a using method, and relates to the technical field of oil and gas well blowout out-of-control rescue. The robot comprises a walking device, a crawler chassis, a main control box, a mechanical arm control box, a mechanical arm assembly, a remote control terminal, a protective cover and a storage battery; the main control box, the mechanical arm control box and the mechanical arm assembly are installed on the crawler chassis, the protective cover is fixed to the crawler chassis, the mechanical arm assembly is connected with the clamping device, the other end of the clamping device is connected with the tool head, the walking device drives a structure on the crawler chassis to move, and the mechanical arm control box is in control connection with the mechanical arm assembly. The main control box is in control connection with the walking device, the mechanical arm control box, the remote control terminal and the storage battery, the problem that after a blowout out-of-control fire occurs, an existing device is difficult to finish bolt cutting, installation and other new and old well mouth replacement work is solved, the dismounting robot replaces personnel to conduct near-well-mouth operation, and the safety of the operation personnel is guaranteed to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of oil and gas well blowout out-of-control rescue, in particular to a wellhead dismantling robot and a use method for oil and gas well blowout out of control and fire. Background technique [0002] Blowout out of control and fire is the most risky accident in the field of oil and gas exploration and development, and it is the first of the eight safety risks of China National Petroleum Corporation. Once a blowout occurs out of control and catches fire, it will cause catastrophic harm to personnel, environment, ecology, resources, etc., and bring extremely bad social impact and extremely huge economic losses to oil and gas companies, which must be quickly controlled. [0003] At present, after a blowout is out of control and catches fire, the old wellhead needs to be removed and a new one needs to be installed. The existing wellhead removal device usually uses a long-distance hydraulic sandblasting cutting dev...
