Abstract
The utility model relates to a drill jumbo propeller is with inlaying type nut, including U type aluminium alloy beam, the oil pipe support, still including inlaying type nut and bolt, wherein, the oil pipe support through inlaying type nut and bolt fastening on U type aluminium alloy beam, the type nut of inlaying install at U type aluminum metal alloy frame frame inboardly, inlay the type nut and include flat portion and highlights. Contrast prior art, the utility model discloses inlay the type nut install at U type aluminum metal alloy frame frame inboard, the installation direction that has changed the bolt to the part that to fix independently comes out, compare the distance of inlaying the outstanding U type aluminium alloy beam internal surface of type nut with the installation of adopting ordinary nut shorter, has effectively reduced the interference risk with other moving part such as hydro -cylinder, in addition inlays type nut simple structure, and the installation and maintenance is convenient.
Description
Technical field
The utility model is related to a kind of mosaic nut, specifically a kind of thruster of jumbo mosaic nut, category
In drill jumbo technical field.
Background technology
Drill jumbo, is a kind of rock drilling equipment of the tunnels and underground engineering using drill bursting construction, and it can move and support
Many rock drills carry out drilling simultaneously.At present, each part on thruster of jumbo is carried out using plain bolt nut
It is fixed.Because each part is arranged on a U-shaped aluminum alloy beams on propeller, its structure is extremely compact, in order to reduce interference wind
Danger, plain nut can be only installed at the outside of aluminum alloy frame, because bolt is more long, cause before rigging up propelling cylinder
The fixed work of all parts on the outside of aluminum alloy frame must be completed, and rig must be removed again when outer part is changed to push away
Enter oil cylinder, workload is very big.
Utility model content
For the problem that above-mentioned prior art is present, the utility model provides a kind of thruster of jumbo mosaic spiral shell
It is female, it is to avoid to produce conflicting for erection sequence with the part inside aluminum alloy beams, simplify disassembly process, other portions such as reduction and oil cylinder
The interference risk of part.
To achieve these goals, the utility model includes U-shaped aluminum alloy beams, oil tube bracket, also including mosaic nut
And bolt, wherein, described oil tube bracket is fixed on U-shaped aluminum alloy beams by mosaic nuts and bolt；Described inlays
Type nut is arranged on U-shaped aluminum alloy beams inner side, and mosaic nut includes flat part and ledge.
Further, the axis through-hole of mosaic nut is machined with dextrorotation internal thread.
Further, in mosaic nut, ledge is machined with sinistral external thread.
Further, U-shaped aluminum alloy beams are provided with the levogyrate inner thread hole with the mosaic nut screw connection.
Contrast prior art, the characteristics of the utility model has following：
1st, mosaic nut is arranged on U-shaped aluminum alloy beams inner side, changes bolt installation direction, so as to need to fix
Part it is independent；
2nd, the distance of the U-shaped aluminum alloy beams inner surface of mosaic nut protrusion is shorter compared with the installation using plain nut,
Effectively reduce the interference risk with other moving components such as oil cylinder；
3rd, mosaic nut structure is simple, installs and easy to maintenance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that peace of the present utility model turns schematic diagram；
Fig. 3 is A-A sectional views in Fig. 2.
Specific embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Figures 1 to 3, a kind of thruster of jumbo mosaic nut, including U-shaped aluminum alloy beams 1, oil tube bracket
2；Also include mosaic nut 3 and bolt 4, wherein, described oil tube bracket 2 is fixed on U by mosaic nut 3 and bolt 4
On type aluminum alloy beams 1；Described mosaic nut 3 is arranged on the inner side of U-shaped aluminum alloy beams 1, and mosaic nut 3 includes flat part
301 and ledge 302.
Further improved as the utility model, the axis through-hole of mosaic nut 3 is machined with dextrorotation internal thread.
Further improved as the utility model, in mosaic nut 3, described ledge 302 is machined with left-handed
External screw thread.
Further improved as the utility model, U-shaped aluminum alloy beams 1 are provided with and the mosaic nut 3 cooperation
Levogyrate inner thread hole.
Contrast prior art, the characteristics of the utility model has following：
Mosaic nut is arranged on U-shaped aluminum alloy beams inner side, changes bolt installation direction, so as to need fixation
Part is independent；
The distance of the U-shaped aluminum alloy beams inner surface of mosaic nut protrusion is shorter compared with the installation using plain nut, has
Effect reduces the interference risk with other moving components such as oil cylinder；3rd, mosaic nut structure is simple, installs and easy to maintenance.
