Pollution caused by stratum, while the scraper caused by casing local deformation also can effectively be avoided to meet card failure, pass through installation
Heat block more ensure that the shaving effect of scraper, by the threaded connector of installation, can be carried out according to the size of drilling tool
It replaces, it is not necessary to entire casing scraper is replaced, it is highly practical, it is suitble to produce use in enormous quantities, can effectively solves background technology
The problems in.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of hydraulic sleeve scraper, including cylinder, top connection and lower contact, the top connection be located at cylinder one end and
Be fixedly connected, the lower contact is located at the cylinder other end and is fixedly connected, the cylinder outer wall surface be provided with No.1 cavity and
No. two cavitys, No. two cavitys are located at No.1 cavity side, and cylinder, the gas is fixedly mounted in No.1 cavity inside bottom end
Cylinder upper end is fixedly connected with scraper, and the scraper upper end face is fixedly connected with blade, the setting of No.1 cavity inner wall both sides
There are sliding rail, the sliding rail internal slide connection sliding block, and sliding block to be located at scraper both ends, No. two cavity insides are fixedly mounted
Heat block.
Further, described top connection one end is provided with flange, and described flange one end is provided with threaded connector.
Further, the top connection is fixedly connected by bolt with threaded connector.
Further, the sliding block is fixedly connected with scraper.
Further, the heat block and cylinder are electrically connected with master controller.
Compared with prior art, the utility model has the advantages that：
1, the utility model is simple in structure, low manufacture cost, passes through the cylinder of installation, it is ensured that blade and internal surface of sleeve pipe
It comes into full contact with, so that it is guaranteed that blade can effectively remove the foreign matter on internal surface of sleeve pipe, one-stop operation is completed drifting, scraping, simplified
Working procedure reduces the pollution caused by stratum, while can also control the flexible of scraper by cylinder, while drifting,
Internal surface of sleeve pipe scraping is neatly carried out, so as to effectively avoid the scraper caused by casing local deformation from meeting card failure.
2, the utility model can pass through heat block pair by the heat block of installation when encountering harder hard wax or salt crust
The hard wax or salt crust of internal surface of sleeve pipe are heated, and are convenient for the scraping of blade, more be ensure that the shaving effect of scraper.
3, the utility model can carry out peace installation and dismantling by bolt by the threaded connector of installation to threaded connector
It unloads, can be replaced according to the size of drilling tool, it is not necessary to replace entire casing scraper, simple operation is highly practical, is suitble to big
Batch production uses.

Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs. 1-3, a kind of hydraulic sleeve scraper, including cylinder 1, top connection 2 and lower contact 3, it is described on connect
First 2 are located at 1 one end of cylinder and are fixedly connected, and the lower contact 3 is located at 1 other end of cylinder and is fixedly connected, 1 outer wall of the cylinder
