Description
Technical field
The present invention relates to tunnel construction apparatus fields, specifically design a kind of half cladding Portable dismantling type shield scraper.
Background technique
The complex formation operating condition of shield-tunneling construction is generally more severe, and abrasion, the failure of scraper are inevitable, and constructs
Replacement cutter is frequently necessary in journey, but due to the limitation of shield machine working environment and working principle, tool changing operating environment is severe, because
The more firm structure of this demand and more convenient and fast mounting means, and conventional drag mounting structure is complicated, disassembly is inconvenient, and shock resistance
Limited capacity is easily fallen off.In case of tool damage or falling off in operation process, all by extreme influence job scheduling.
Chinese patent CN 201420638556.9 discloses a kind of shield machine scraper mechanism, includes mainly scraper body, scrapes
Knife pedestal, shield machine spoke mainboard, the scraper pedestal are welded on shield machine spoke mainboard, and the scraper body cutter hub is logical
It crosses bolt to be fastened with tool apron, a raised step is arranged in one end of the scraper pedestal, sets at the cutter head of the scraper body
A cutter head eave tile is set, the raised step and the cutter head eave tile are coupled.But fastening spiral shell when scraper replacement, installation
Bolt needs biggish pretightning force, and the replacement operation environment crossed in the construction process is harsh, space is limited, and mechanically aided tool can not
It brings into or flexibly uses, warehouse entry tool changing task difficulty is big, and the structure is easily caused connection bolt by front or side impact
Failure, so that insecure be easy to happen of Cutting tool installation manner falls off etc. for topic all extreme influence project progress.
Chinese patent CN201520209895.X discloses a kind of novel combination type shield scraper, mainly by scraper body,
Fixation is bolted in alloy body, wearing layer, bolt and the tool apron composition being fixed on cutter head panel, the scraper body
On tool apron, the scraper body back side is provided with positive stop lug boss, location and installation slot and positioning groove, and the tool apron is equipped with and determines
The positive stop lug boss of position mounting groove cooperation and the clamping convex platform cooperated with positioning groove.But the connection bolt of the scraper is easy to lose
Effect and installation and replacement are difficult, and cutter hub is much higher by mounting base, considerably increases what scraper was subject in use in this way
Resistance, and the scraper body is when by side impact force, other than bolt, branch of the scraper body without other support forces
Support is easy to cause scraper damage deformation in this way, greatly reduces the service life and cost of scraper.
