Abstract
The invention discloses a shield cutter holder and spoke connecting structure which comprises a cutter holder and a spoke. Stepped through holes in the radial direction of the spoke are formed in the large planes of two sides of the cutter holder through machining, threaded holes coaxial with the stepped through holes are formed in the spoke through machining, and the cutter holder is fastened on the outer surface of the spoke through bolts. When the cutter holder is damaged, the connecting bolts can be easily dismounted, a new cutter holder can be replaced, the maintenance speed is improved, working efficiency is improved, and the shield cutter holder and spoke connecting structure has the advantages of being low in manufacture cost, easy to install, convenient to maintain and the like.
Description
Technical field
The present invention relates to a kind of syndeton, refer to the syndeton of a kind of shield structure tool rest and spoke especially.
Background technology
For the cutterhead of balancing earth-pressure shielding machine, usually adopt tool rest to be welded on spoke is fixedly connected with mode, if in shield machine tunneling construction process, tool rest is damaged, then change very inconvenient, and maintenance difficulty is large, and extreme influence construction speed.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcome in background technology, provides the syndeton of a kind of shield structure tool rest and spoke, and the syndeton of this shield structure tool rest and spoke is with bolts, can easy removal, is convenient for changing and maintenance.
For solving the problem, the present invention takes following technical scheme:
The syndeton of a kind of shield structure tool rest of the present invention and spoke, comprise tool rest, spoke, five column structures that described tool rest is one side is Inner arc, all the other four sides are plane, the cross section of described spoke is rounded, the inner arc surface of described tool rest and the outer round surface of spoke are fitted completely, the large plane in both sides of described tool rest is processed with the ladder hole along spoke radial direction, described spoke is processed with the screwed hole coaxial with ladder hole, and described tool rest is fastened by bolts on the external surface of spoke.
The syndeton of a kind of shield structure tool rest of the present invention and spoke, owing to being processed with the ladder hole along spoke radial direction in the large plane in the both sides of tool rest, described spoke is processed with the screwed hole coaxial with ladder hole, described tool rest is fastened by bolts on the external surface of spoke, therefore, when tool rest is damaged, can connecting bolt under easy removal, the tool rest more renewed, the syndeton of the present invention's a kind of shield structure tool rest and spoke, improve maintenance speed, improve operating efficiency, there is low cost of manufacture, easily install, go along with sb. to guard him the advantages such as convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the syndeton of a kind of shield structure tool rest of the present invention and spoke, comprise tool rest 1, spoke 2, five column structures that described tool rest 1 is one side is Inner arc, all the other four sides are plane, the cross section of described spoke 2 is rounded, the inner arc surface of described tool rest 1 and the outer round surface of spoke 2 are fitted completely, the large plane in both sides of described tool rest 1 is processed with the ladder hole 3 along spoke 2 radial direction, described spoke 2 is processed with the screwed hole 4 coaxial with ladder hole 3, and described tool rest 1 is fastened on the external surface of spoke 2 by bolt 5.
Should be noted that; the foregoing is only the preferred embodiments of the present invention, be not limited to the present embodiment, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
