Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this Utility model embodiment is described in further detail.
As it is shown in figure 1, also can be found in Fig. 2-Fig. 3, the utility model embodiment provides a kind of dismounting packing box The instrument of pressure cap, the instrument of this dismounting packing box pressing cap includes pressure cap fixed part 1 and handle 2;
Pressure cap fixed part 1 is cylinder, and pressure cap fixed part 1 is provided with through hole 3 vertically, and the size of through hole 3 is bigger In the size of packing box pressing cap, and the size of the box body less than packing box, pressure cap fixed part 1 is radially provided with Opening 4, opening 4 connects with through hole 3, and the width of opening 4 is more than the diameter of polished rod, and is less than packing box pressure Distance between the relative two sides of cap;
Handle 2 is along the radially fixed outside at pressure cap fixed part 1 of pressure cap fixed part 1;
The upper end external belt being enclosed within packing box pressing cap by pressure cap fixed part 1 moves packing box pressing cap rotation, passes through Handle 2 drives pressure cap fixed part 1 to rotate.
The upper end cross section profile of packing box pressing cap is regular hexagon, its lower end stretch into the tray interior of packing box with The box body threaded engagement of packing box, the size of the box body of packing box is more than the size of packing box pressing cap upper end.
In the utility model embodiment, the width of opening 4 is more than the diameter of polished rod, and is less than packing box pressure Distance between the two sides that cap upper end is relative, the size being slightly larger in dimension than packing box pressing cap of through hole 3 and little In the size of the box body of packing box, when using the utility model dismounting packing box pressing cap, first pass through this practicality Novel opening 4 makes pressure cap fixed part 1 of the present utility model be enclosed within outside the polished rod above packing box pressing cap, Staff moves down the utility model, makes pressure cap fixed part 1 of the present utility model be enclosed within outside packing box pressing cap Portion, then staff pulls handle 2, handle 2 to drive pressure cap fixed part 1 to rotate, and pressure cap fixed part 1 carries Dynamic packing box pressing cap rotates, and then is disassembled by packing box pressing cap.Owing to the width of opening 4 is less than packing Distance between box pressing cap opposite sides face, during dismounting packing box pressing cap, packing box pressing cap will not Deviate from from opening 4, and the size of the box body being smaller in size than packing box due to through hole 3, pass through packing box Box body the utility model is carried out spacing, prevent the utility model from falling to down-hole.
After packing box pressing cap has been dismantled, staff carries the utility model by handle 2, makes polished rod Spill at opening 4, be then displaced outwardly the utility model, the utility model can be taken off.
Wherein, the size being slightly larger in dimension than packing box pressing cap of through hole 3, refer specifically to when by of the present utility model When pressure cap fixed part 1 is enclosed within packing box pressing cap, the inner circumferential of pressure cap fixed part 1 coordinates with packing box pressing cap Distance between face be less than certain numerical value, such as less than 2 millimeters;The box body being smaller in size than packing box of through hole 3 Size, refer specifically to the box body of the vertical tangent plane of a certain position and packing box on the outline of pressure cap fixed part 1 Outline vertical tangent plane in, in parallel and distance between the tangent plane of its nearest neighbours is more than a fixed number Value, such as larger than 2 millimeters.The size and shape of the size of through hole 3 specifically can be enclosed within pressure cap fixed part 1 On packing box pressing cap, and packing box pressing cap rotation during pressure cap fixed part 1 Forced rotation, can be driven to be as the criterion.
The utility model is provided with through hole 3 vertically by pressure cap fixed part 1, is radially provided with opening 4, opening 4 connect with through hole 3, and the utility model is enclosed within through polished rod the outside of packing box pressing cap by opening 4, due to The size being slightly larger in dimension than packing box pressing cap of through hole 3 and the size of the box body less than packing box, opening 4 Distance between the width diameter more than polished rod and the opposite sides face less than packing box pressing cap, dismantles packing box During pressure cap, the utility model is difficult to down-hole, thus eliminates and deposit to down-hole because the utility model falls Potential safety hazard, it is to avoid stop well salvage, affect oil well and normally produce, and packing box pressing cap can not be from opening Deviate from mouth 4, it is simple to dismounting packing box pressing cap.
In the utility model embodiment, handle 2 is threadeded or one-body molded with pressure cap fixed part 1, its In, handle 2 is threadeded with pressure cap fixed part 1 can be easy for removal and installation, handle 2 and pressure cap fixed part 1 Integrated structure is the most firm, certainly, skilled person will appreciate that, handle 2 and pressure cap fixed part 1 Between also can connect by double threaded screw is fixing.
As it is shown in figure 1, also can be found in Fig. 2 to Fig. 3, in the utility model embodiment, handle 2 is provided with two Root, and two handles 2 are oppositely arranged along the circumference of pressure cap fixed part 1, uniform force, it is simple to dismounting packing Box pressing cap.
As it is shown in figure 1, also can be found in Fig. 2, Fig. 4 or Fig. 5, in the utility model embodiment, pressure cap is solid Determine portion 1 and include 11, at least two pieces of compact heaps 12 of outer sleeve and at least two screw rods 13;
Outer sleeve 11 is cylinder, and outer sleeve 11 is radially provided with opening 4;
At least two pieces of compact heaps 12 are arranged along the inner circumferential of outer sleeve 11, at least two screw rods 13 with at least two pieces Compact heap 12 one_to_one corresponding, one end of the every screw rod 13 at least two screw rods 13 is respectively and therewith corresponding Compact heap 12 fixing connect, the other end is passed by outer sleeve 11, and every screw rod 13 is all and outer sleeve 11 threaded engagement, coordinate drive at least two pieces of compact heaps 12 every by every screw rod 13 with outer sleeve 11 The radial motion of the relative outer sleeve 11 of block compact heap 12, coordinates clamping packing by least two pieces of compact heaps 12 Box pressing cap.
During using the utility model dismounting packing box pressing cap, the opening 4 first passed through on outer sleeve 11 makes Pressure cap fixed part 1 is enclosed within outside polished rod, then moves down the utility model, makes pressure cap fixed part 1 be enclosed within packing Outside box pressing cap, regulate the every screw rod 13 at least two screw rods 13, to regulate at least two pieces of compact heaps The position of every piece of compact heap 12 in 12, makes every piece of compact heap 12 compress the surface of packing box pressing cap respectively, from And clamp packing box pressing cap, then drive pressure cap fixed part 1 to rotate by handle 2, and then dismounting packing Box pressing cap.
The instrument of the dismounting packing box pressing cap that the utility model embodiment provides, is applicable to dismantle polished rod size Less than opening 4 width, and the distance of the relative two sides of packing box pressing cap is more than opening 4 width and less than extremely The packing box pressing cap of the maximum sized oil wells in field of the packing box pressing cap that few two pieces of compact heaps 12 can clamp, The scope of application is wider.
Certainly, skilled person will appreciate that, pressure cap fixed part 1 is alternatively structure as shown in Figure 6, its The cross section profile of through hole 3 is the regular hexagon matched with the outline of end section on packing box pressing cap, it is adaptable to Dismounting uses the packing box pressing cap that national standard or professional standard manufacture, and its simple in construction is firm, and is easy to tear open Unload packing box pressing cap.
As it is shown in figure 1, also can be found in Fig. 2, Fig. 4 or Fig. 5, in the utility model embodiment, at least two The quantity of block compact heap 12 is three pieces.
