Abstract
The utility model discloses a cutter box installation structure of tip teeth for shield machines, which comprises a cutter holder and the cutter box for fixing cutters. The cutter holder is provided with a cutter reserved-port, and the cutter box is embedded in the cutter holder from top to bottom. The left end and the right end of the cutter box are provided with incline-shaped supporting blocks and are respectively connected with incline-shaped wedges. The front end and the rear end of the cutter box are provided with cutter fixing ends, grooves matched with the cutter fixing ends are arranged at the front end and the rear end of the cutter holder, and the cutter fixing ends and the grooves are locked tightly through the wedges. The cutter box is embedded in the cutter holder from top to bottom and the inclined-shaped supporting blocks are connected with the incline-shaped wedges, thereby restricting lateral motion of the cutters. The grooves matched with the cutter fixing ends are arranged at the front end and the rear end of the cutter holder, and the cutter fixing ends and the grooves are locked tightly through the wedges, thereby having supporting effect on the cutters and also preventing the cutters from moving back and forth. The cutter box installation structure of the tip teeth for the shield machines has the advantages of being reliable in installation and convenient to mount and dismount.
Description
Technical field
The utility model relates to a kind of mounting structure of shield machine cutter, relates in particular to the mounting structure of a kind of shield machine with the cutter cutter box of going ahead of the rest.
Background technology
The operating mode of shield-tunneling construction is generally comparatively abominable, and the wearing and tearing of cutter are inevitably, often needs to change cutter in the work progress; But because the restriction of shield machine working environment and operating principle causes before cutter head of shield machine, changing cutter and has bigger risk, because the restriction of go ahead of the rest knife structure and position; Cutter generally is fixed by bolts on the cutter head of shield machine in advance; Simultaneously, in the shield machine tunneling process, the cutter that needs sometimes to go ahead of the rest is replaced with hobboing cutter; But the screwed hole on cutterhead or the cutter box usually damages, because the abominable situation reparation of the restriction in space and operating mode is to be difficult to realize.How to realize that cutter in advance not only installed the difficult point that firm but also easy accessibility just becomes shield-tunneling construction.
The utility model content
The purpose of the utility model is to provide the mounting structure of a kind of shield machine with the cutter cutter box of going ahead of the rest, and to solve the cutter of going ahead of the rest at present the problem that the back dismounting bothers is installed, and has the advantage that firm and easy accessibility are installed.
The purpose of the utility model is to realize through following technical scheme:
A kind of shield machine comprises the cutter box of tool rest and fixed cutting tool with the mounting structure of the cutter cutter box of going ahead of the rest, and has the cutter reserved opening on the said tool rest; Said cutter box embeds tool rest from the bottom to top; The right ends of said cutter box is provided with oblique back-up block, and connects oblique chock respectively, and the rear and front end of cutter box is provided with the cutter fixed end; The rear and front end of said tool rest has the groove that matches with said cutter fixed end, and each other through chock locking.
Said oblique back-up block connects oblique chock through bolt.
Said chock adopts up-narrow and down-wide block structure, and is fastened on the tool rest through bolt.
The beneficial effect of the utility model is: through cutter being fixed in the cutter box, have the cutter reserved opening on the tool rest, the cutter box embeds tool rest from the bottom to top; Oblique back-up block connects oblique chock through bolt; Tight a bolt, oblique chock is to shifted laterally and lock the cutter box, has limited the cutter move left and right; Have the groove that matches with the cutter fixed end through rear and front end, and, cutter has been played the effect of supporting, and limited moving forward and backward of cutter, have advantage firm and easy accessibility is installed each other with chock locking at tool rest.
