Abstract
The utility model belongs to the technical field of oil exploration solid control equipment and relates to an explosion proof type coupling guard for solid control equipment. The coupling guard comprises a guard base body frame, a lining explosion proof plate and an active window, wherein the guard base body frame is of a gate type space frame structure, the lining explosion proof plate is fixed at the inner side of the guard base body frame, and the active window for opening and locking is formed at the top surface and the upper part of one side face of the guard base body frame. The lining explosion proof plate is formed by an explosion-proof material, so sparks cannot be generated due to the friction and impact of a metal coupling and metal components thereof, safety loopholes are avoided, and on-site requirements in the explosion proof aspect are met.
Description
Technical field
The utility model belongs to the solid control equipment field in oil exploration, relates to a kind of solid control equipment explosion-proof type coupling shield.
Background technology
At present in oil exploration drilling system, because have flammable explosive gas and liquid to exist, meet spark, naked light etc. and can produce the potential safety hazards such as burning, blast, so the plant equipment in solid control equipment and electric fixtures, be all that requirement possesses certain explosive-proof grade, be generally dIIBT4.
The various types of shaft couplings that use in drilling equipment are at present all with metal assembly, be arranged on the coupling shield of shaft coupling periphery, also be all to have iron plate or steel plate materials to form, in guard shield, the unexpected contact friction of the shaft coupling of High Rotation Speed and guard shield or shaft coupling damage assembly fly out while striking on guard shield, guard shield is inner to be consisted of bursting diaphragm material because being lined with bursting diaphragm or guard shield itself, so after friction or shock, can not produce spark or naked light, do not have potential safety hazard, meet on-the-spot requirement of explosion proof.
Before device start, should hand turning, rotating machinery, in checkout facility, whether there are friction or stuck phenomenon, but at present solid control equipment can be used for jiggering with the active window that coupling shield does not all have to open and to lock, and hand can not be stretched, and does not use space and the position of setting stick car.
Utility model content
The utility model object is to provide explosion-proof type coupling shield structure for a kind of drilling well solid control equipment, meets the requirement of drilling well solid control equipment aspect explosion-proof, eliminates site safety hidden danger.
For reaching above-mentioned target, this drilling well solid control equipment is comprised of guard shield base frame and liner bursting diaphragm with explosion-proof type guard shield.Bursting diaphragm is to consist of explosion-proof lamp, and explosion-proof lamp comprises: the materials such as nonmetals, part non-ferrous metal.
A kind of explosion-proof type coupling shield, comprise guard shield base frame, liner bursting diaphragm and active window, guard shield base frame is door type space frame structure, liner bursting diaphragm is fixed on guard shield base frame inner side, and the active window that is used for unlatching or locks is formed at the top of the end face of guard shield base frame and a side.
Accompanying drawing explanation
Fig. 1 is the structure chart that the active window of coupling shield is opening
Fig. 2 is the structure chart that the active window of coupling shield is closed condition
1, guard shield base frame 2, liner bursting diaphragm 3, active window
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further
In Fig. 1: a kind of explosion-proof type coupling shield, comprise guard shield base frame 1, liner bursting diaphragm 2 and active window 3, guard shield base frame 1 is door type space frame structure, liner bursting diaphragm 2 is fixed on guard shield base frame inner side, and the top of the end face of guard shield base frame and a side is the active window 3 for opening or locking.
The active window 3 that can open and lock, can be before starting device, use hand rotating machinery, whether checkout equipment inner rotation part there is scratching, friction, stuck phenomenon, problem is revealed in advance, avoid hidden danger to occur, check that the active window 3 that can open and lock after errorless is locked on guard shield base frame 1 and liner bursting diaphragm 2, then row starting device.
Fig. 2 is that the active window 3 that can open and lock is locked at the state on guard shield base frame 1 and liner bursting diaphragm 2.
Claims (1)
1. an explosion-proof type coupling shield, it is characterized in that, comprise guard shield base frame, liner bursting diaphragm and active window, guard shield base frame is door type space frame structure, liner bursting diaphragm is fixed on guard shield base frame inner side, and the active window that is used for unlatching or locks is formed at the top of the end face of guard shield base frame and a side.
