Description

Technical Field

[0001] The utility model belongs to the technical field of drilling and production, and in particular relates to a pneumatic linear wiper device used in a driller's room. Background Art

[0002] The driller's control room is the core component of the control and display system, and is also the control center of the oil rig. It is hailed as the "heart" of the oil rig by the industry. The quality of its performance is directly related to the production efficiency, maintenance performance, labor intensity and production safety of the entire rig. The important position of the driller's room in the design and manufacture of the entire oil rig is self-evident. The design and manufacture of the driller's control room of the oil rig is a very complex and tedious system engineering. During the whole process, it is necessary to realize the overall detection and control of the rig by the driller, and to take into account the functional requirements of effective explosion-proof, protection, anti-corrosion, shock-proof, heat insulation, cold-proof, and sound insulation. The environment in which oil drilling takes place is relatively harsh, and the driller's room is set up at the drilling site, so that the driller's room is always exposed to the outside. Whether it is cloudy or rainy, the operator needs to concentrate on work, and the external environment will have a great impact on the operator; at present, due to the large size of the driller's room, the explosion-proof glass on it is long, and the size of the wiper operating screen is large. The original swing wiper is driven by the pneumatic motor in the actuator to make a fan-shaped movement. On the one hand, this method has the disadvantage of cleaning dead corners and rainwater is not wiped cleanly, affecting the operating field of vision. On the other hand, due to the long glass and the long swing wiper, there is a disadvantage of insufficient power during the movement, which affects the use effect; and the linear wiper with a toothed belt structure is affected by the external temperature. The toothed belt shrinks in a low temperature environment and the toothed belt has a pull-off failure phenomenon. In a high temperature environment, the toothed belt stretches and slips, resulting in transmission failure. Therefore, it is necessary to make improvements to the above problems.
