Description
Technical field
The utility model relates to oil-well drilling equipment, especially a kind of guide rail step welding point.
Background technique
It during wellbore construction, often to carry out top and drive drilling well, wherein top drive apparatus is to carry out top to drive the important of drilling well
One ring, the normal operation of top drive apparatus are oriented to and are born countertorque by guide rail, but guide rail it is longer cannot process it is integral,
For this purpose, guide rail needs segmental machining, on-site assembly is carried out, but since field condition is limited, guide rail is processed just by the limit of field condition
System, the installation of guide rail are decided by whether the connector of guide rail is convenient and safety, at present guide rail connection are consolidated using hook plug-in type
Fixed structure, scene is using more convenient, still, due to existing using welding combination, and without location structure, so that processing is again
Good, technical parameter is not still up to standard after assembling forming, and using effect is poor and causes guide rail disassembly assembling difficult, therefore, guide rail connection
The improvement and innovation of connector are imperative.
Utility model content
For above situation, for the defect for overcoming the prior art, the purpose of the utility model is to provide a kind of guide rail step
Welding point can effectively solve current guide rail and be connected and fixed that effect structure is bad, guide rail disassembly assembling is difficult, assembling is not achieved and wants
The problem of asking.
The technical solution that the utility model solves is a kind of guide rail step welding point, including main body, outside in the middle part of main body
It is welded with the guide plate positioning welding step around main body circumference on wall, there is the beveling for welding on guide plate positioning welding step
Mouthful, body top center is provided with vertical guide plate welding groove, and it is consecutive that guide plate welding groove by body top extends to guide plate tack welding
Rank lower part, the side that the following position of guide plate positioning welding step is located in main body are provided with upper and lower T-slot, the upper end structure of T-slot
At backing pin slot, lower end constitutes pocket for the punch head, and lower body part is provided with load pin hole, is provided with positioning in ipsilateral main body with load pin hole
Hole, the center of location hole and the bottom surface of guide plate positioning welding step are the same as high.
The utility model structure is simple, and novel and unique is easy to install and use, and effect is good, improves guide rail in handling
Safety in particular improves the interchangeability of product, is the innovation on rail joint, and economic and social benefit is significant.
Detailed description of the invention
Fig. 1 is the utility model structural front view.
Specific embodiment
It elaborates below in conjunction with attached drawing to specific embodiment of the present utility model.
As shown in Figure 1, a kind of guide rail step welding point of the utility model, including main body 1, on 1 middle part lateral wall of main body
It is welded with the guide plate positioning welding step 6 around 1 circumference of main body, there is the angular cut for welding on guide plate positioning welding step 6,
1 central upper portion of main body is provided with vertical guide plate welding groove 5, and guide plate welding groove 5 is consecutive by extending to guide plate tack welding at the top of main body 1
6 lower part of rank, the side that the following position of guide plate positioning welding step 6 is located in main body 1 are provided with upper and lower T-slot 8, T-slot 8 it is upper
End constitutes backing pin slot 4, and lower end constitutes pocket for the punch head 3, and 1 lower part of main body is provided with load pin hole 2, in the main body 1 ipsilateral with load pin hole 2
It is provided with location hole 7, the center of location hole 7 and the bottom surface of guide plate positioning welding step 6 are the same as high.
In order to guarantee using effect and easy to use,
The main body 1 is rectangle.
The guide plate positioning welding step 6 is the small annular table scalariform upward along axis center in the big top in lower part.
The backing pin slot 4 on 8 top of T-slot and the pocket for the punch head 3 of lower part is open relatively, and identical, is symmetrical with T-slot cross
Both sides above and below to central axes.
Insertion of the guide plate welding groove 5 for guide plate positions, and carries out welded connecting fixation with guide plate, and guide plate tack welding is consecutive
The stiffening plate positioning welding of oblique groove and guide plate two sides on rank 6 guarantees that rail joint size will not shift, and securely
Reliably.
When the utility model is specifically used, by the utility model guide rail step welding point and guide plate and two sides stiffening plate into
Row welds together, and forms a section guide rail, a section section guide rail is combined through series connection and is connected, then plugs load pin, guide rail can
To use, when needing to dismantle guide rail, it is only necessary to take out load pin, separation single-unit guide rail can smoothly complete.Rail joint
It is divided into pin end and female connector, they are used in conjunction with each other, and connector is public when butt welding with respective guide rail butt welding after processing
Connector can not position, it is possible to and more welderings or few weldering lead to pin end cause different in size, after last pin and box sub docking, connector
Gap may be big, or does not connect, and the guide plate welding groove 5 on guide rail is fluting, is directly inserted into guide plate welding for guide-rail plate
It in slot 5, is welded, intermediate empty portion is easy for interior external welding to reinforce weld strength, and pocket for the punch head 3 is connect for hooking mother
Head, backing pin slot 4 is the depth within the pin extreme higher position limited in female connector, that is, insertion female connector, and location hole 7
It is equally this kind of function, it is corresponding with the arc groove that female connector is opened, when the circular arc on female connector goes upward to pin end location hole 7,
The load pin hole 2 that can stop uplink lowest part is for bolt, after in pin end insertion female connector, in place, directly
It is inserted into load pin hole 2, pin and box sub just completes connection procedure, becomes an entirety, and upper/lower guide becomes straight line, work
Tool can be run back and forth above.
The utility model structure is simple, easy to install and use, improves guide rail step welding point interchangeability, reduces and lead
Rail step welding point difficulty of processing, economizes on resources, and is suitable in the top drive guide rail in the drilling wells such as petroleum, geology, the hydrology, coal mine
It uses, is the innovation on rail joint, social and economic benefit is significant.
