And the cutter has problems in the tunneling process, so that the cutter is difficult to find, serious consequences such as cutter head damage are easy to cause, and a large construction risk exists.

Chinese patent CN210637078U "a shield constructs locking structure that moves of hobbing cutter" the utility model discloses a shield constructs locking structure that moves of hobbing cutter, including toolbox, hobbing cutter, blade holder, briquetting and tensioning block, on the blade holder was located to the hobbing cutter, on the toolbox was located to the blade holder, on the tensioning block was located to the briquetting, tensioning block and blade holder bolted connection, the blade holder was equipped with the steel billet, and the steel billet is equipped with puller plate, puller plate and steel billet bolted connection, puller plate and tensioning block bolted connection. The fixed position is arranged on the tensioning block, and a tool apron is not fixed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a shield constructs novel blade holder of construction solves the cutter and receives vertical direction and horizontal direction impact load, under the exogenic action, takes place the displacement easily between cutter and the blade holder, and then the tensioning block takes place to remove, withdraws from, leads to the blade disc cutter to take place not hard up, the problem that drops even this moment.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a shield constructs novel blade holder of construction, includes toolbox, cutter, blade holder, tensioning block and cushion, and the cutter is established at the blade holder upper surface, and the blade holder is established in toolbox one side, and the opposite side is equipped with tensioning block, and tensioning block supports and leans on blade holder one end and through the taut blade holder of taut nut direction, and the blade holder lower surface is equipped with the side boss, and taut piece terminal surface supports and leans on the boss of side.

Preferably, a wedge block is arranged between the end surface of the tensioning block and the side lug boss.

In the preferred scheme, the blade holder lower surface is equipped with the fixed slot, and the cushion is established inside the fixed slot with taut piece.

In the preferred scheme, a wedge groove is formed in one side of the fixing groove, and the wedge block is arranged inside the wedge groove.

In the preferred scheme, taut piece terminal surface is equipped with puts the thing groove, and the voussoir control is put between thing groove and the wedge groove.

In a preferable scheme, the height of the side raised platform is 0.8-1.5 cm.

In a preferable scheme, the width of the side boss is 0.8-1.5 cm.

The utility model provides a shield constructs novel blade holder of construction, the utility model discloses the technical scheme who adopts is: and bosses are respectively added on two sides of the cutter holder, and the height and the width of each boss are respectively 1 cm. The cutter cushion block is normally arranged above the boss, and the boss can effectively prevent the cutter from moving relative to the tunnel face after the cutter is impacted with the tunnel face, so that the cutter is loosened and even falls off. Compact structure is practical, is worth extensively promoting.

Detailed Description

As shown in figures 1-5, a novel cutter holder of shield construction, including tool box 1, cutter 6, cutter holder 5, tensioning block 2 and cushion 4, cutter 6 establishes at cutter holder 5 upper surface, and cutter holder 5 establishes in tool box 1 one side, and the opposite side is equipped with tensioning block 2, and tensioning block 2 supports and leans on at cutter holder 5 one end and through the taut cutter holder 5 of 3 directions of tensioning nut, and cutter holder 5 lower surface is equipped with side boss 502, and tensioning block 2 terminal surface supports and leans on side boss 502. The improvement is that a side boss 502 is additionally arranged below the tool apron 5, and the improvement can reduce the loosening, falling off and the like of the tool 6 caused by shield tunneling. Through increasing the design of side boss 502 on traditional blade holder 5, make cutter tensioning block 2 can be more stable, avoid tensioning block 2 to take place to remove, cause the not hard up condition of cutter 6 to effectual having reduced in the shield structure work progress because of the impact of tunnelling in-process, collision cause the not hard up probability that drops of cutter 6, the effectual efficiency of construction that has improved.

Preferably, a wedge 7 is arranged between the end surface of the tensioning block 2 and the side convex platform 502. The wedge 7 serves to increase the abutting area of the end surface of the tension block 2 against the side bosses 502 and also to prevent the tension block 2 from directly contacting the side bosses 502 to damage the end surfaces of the side bosses 502.

In a preferred scheme, the lower surface of the cutter holder 5 is provided with a fixing groove 501, and the cushion block 4 and the tensioning block 2 are arranged inside the fixing groove 501. The structure shown in fig. 3 effectively reduces the moving space of the tensioning block 2 between the tool holder 5 and the tool 6 by adding the fixing groove 501, and can control the fixed relative position after installation, and the structure needs to be used according to the size of the tensioning block 2.
