Abstract
The utility model discloses a welded sleeve used on a power head of a rotary drilling rig. The welded sleeve is characterized in that: the welded sleeve is formed by connecting an upper flange, a sleeve body, a connecting flange and a lower flange through welding, wherein the upper flange, the connecting flange and the lower flange are forged by adopting blanks; and the sleeve body is formed by rolling and welding a plate. Compared with the conventional integrally-cast-type power head used in the power head of the rotary drilling rig, the welded sleeve greatly reduces the defects such as slag inclusion, air holes and the like, reduces oil leakage faults of the sleeve, simultaneously reduces cutting machining amount, improves the rate of finished products, effectively reduces cost, shortens a machining period, has a simple and practical overall structure, and can be widely used on power heads of various rotary drilling rigs.
Description
Technical field
The utility model relates to a kind of rotary drilling rig, particularly a kind of welded type sleeve that is used on the rotary digging drill power head.
Background technology
Rotary drilling rig is the efficient pore-forming equipment of heavy caliber that uses in a kind of foundation construction, and the drilling rod that its utilization remains vertical direction directly rotates, excavates ground, thereby forms the stake hole of the required diameter and the degree of depth fast on ground.This rotary drilling rig since power big, power is strong, easy to use, pore-forming is quick, so in the foundation construction process of the engineering of being widely used in, building.Existing rotary digging drill power head adopts the monoblock cast structure, process-cycle is long, and blank turning amount is big, and serious is that casting process is easy to generate defectives such as pore, slag inclusion, often be to be worked into half to pinpoint the problems, cause scrapping, cause heavy losses, more have serious to company, because tiny pore fails to find, cause unit head leakage of oil in use for some time, bring loss, impact to corporate image to the user.
The utility model content
The utility model is to provide a kind of easy to process, service-strong to be used for the welded type sleeve on the rotary digging drill power head, to solve shortcoming in the above-mentioned background technology with not enough.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of welded type sleeve that is used on the rotary digging drill power head is characterized in that, its by upper flange, cylindrical shell, adpting flange and lower flange by being made of welded connection.
In the utility model, described upper flange, adpting flange, lower flange adopt blank forging, and cylindrical shell adopts sheet material to roll seam and forms.
Beneficial effect: compare the monoblock cast formula unit head that existing rotary digging drill power head uses, the utility model has significantly reduced defectives such as slag inclusion, pore, reduced the generation of sleeve oil leakage fault, reduced the machining amount simultaneously, improved yield rate, effectively reduced cost, shortened the process-cycle.Its overall structure is simple, practical, can be widely used on the unit head of various rotary drilling rigs.
Description of drawings
Fig. 1 is the structural representation that partly cuts open of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete accompanying drawing, further set forth the utility model:
Referring to Fig. 1, a kind of welded type sleeve that is used on the rotary digging drill power head comprises upper flange 1, cylindrical shell 2, adpting flange 3 and lower flange 4.Wherein upper flange 1, adpting flange 3 and lower flange 4 adopt rough forging, and cylindrical shell 2 adopts sheet material to roll seam.Its middle cylinder body 2 use the steel plate reel earlier, and seam becomes cylinder, goes out the groove equidimension of welding with each part through preliminary working again.Upper flange 1, adpting flange 3 and lower flange 4 first rough forgings, back preliminary working goes out the groove equidimension with various welding.Upper flange 1, cylindrical shell 2, lower flange 4 assembly weldings are welded to connect flange 3 at last then, form welded type sleeve integral workblank.Then blank is carried out fine finishining, finish final welded type sleeve.Rough forging and sheet material have effectively improved blank quality, do not have the defective such as slag inclusion, pore of cast blank, greatly reduce the generation of sleeve oil leakage fault.Compare foundry goods, can reduce the machining amount, improve yield rate, effectively reduce cost, shorten the process-cycle.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. a welded type sleeve that is used on the rotary digging drill power head is characterized in that, its by upper flange, cylindrical shell, adpting flange and lower flange by being made of welded connection.
2. a kind of welded type sleeve that is used on the rotary digging drill power head according to claim 1 is characterized in that, described upper flange, adpting flange, lower flange adopt blank forging, and cylindrical shell adopts sheet material to roll seam and forms.
