Description
技术领域technical field

背景技术Background technique
盾构机钢套筒始发时根据平衡原理研发的一种新型施工工艺，钢套筒始发时盾构机下井前，先将钢套筒下半部分安装到始发井指定位置，并在套筒内底部进行适当的回填，然后将盾构吊装下井，最后将钢套筒安装完毕，继续回填。通过这个钢套筒封闭空间提供平衡掌子面的水压力，盾构机在钢套筒内实现安全始发。该技术已在盾构施工中逐步推广使用。然而，这种始发也有一定的局限性，钢套筒支座对盾体的摩擦阻力力矩、掌子面摩阻力矩和套筒内回填物对盾体外壳的摩阻力矩等不足以克服盾构机刀盘的旋转力矩时，盾体可能会发生旋转，造成钢套筒装置失稳，进而可能始发失败，造成施工重大风险。A new construction technology developed according to the principle of balance when the steel sleeve of the shield machine is launched. Properly backfill the inner bottom of the casing, then hoist the shield down into the well, and finally install the steel casing and continue backfilling. The closed space of this steel sleeve provides the water pressure to balance the tunnel face, and the shield machine realizes safe starting in the steel sleeve. This technology has been gradually promoted and used in shield tunneling construction. However, this kind of initiation also has certain limitations. The frictional resistance moment of the steel sleeve support to the shield body, the frictional resistance moment of the face of the tunnel, and the frictional resistance torque of the backfill in the sleeve to the shield shell are not enough to overcome the shield. When the rotational torque of the machine cutter head is increased, the shield body may rotate, resulting in the instability of the steel sleeve device, which may lead to failure of initiation, causing major risks in construction.

如图1-4所示，本实用新型提供一种互锁的螺纹式盾构机防扭转装置，其将盾体10临时限位在一对轨道12上，以防止盾体10在钢套筒11内旋转，其特征在于，包括：As shown in Figures 1-4, the utility model provides an interlocking anti-twist device for a threaded shield machine, which temporarily limits the shield body 10 on a pair of rails 12 to prevent the shield body 10 from falling on the steel sleeve. 11. Internal rotation, characterized in that it includes:
一对通孔，其相对设置于所述盾体上；a pair of through holes, which are oppositely arranged on the shield body;
一对螺纹套筒8，其为筒状且分别同轴贴合设置于一对所述通孔内，螺纹套筒8的外端的外侧壁向外凸起形成凸台，所述凸台的顶面内嵌一圈与螺纹套筒8同轴的第一O形密封圈9；A pair of threaded sleeves 8, which are cylindrical and coaxially fitted in a pair of through holes respectively, the outer side walls of the outer ends of the threaded sleeves 8 protrude outwards to form bosses, and the tops of the bosses A first O-ring 9 coaxial with the threaded sleeve 8 is embedded in the surface;
一对螺杆1，其与所述螺纹套筒8一一对应，所述螺杆1的中部螺纹连接在对应的螺纹套筒8内，从而使得螺杆1的外端能伸出或缩回至套筒内，所述螺杆1的外端的横截面均为正十二边形；A pair of screw rods 1, which correspond to the threaded sleeves 8 one by one, and the middle part of the screw rods 1 is screwed into the corresponding threaded sleeves 8, so that the outer ends of the screw rods 1 can be extended or retracted into the sleeves , the cross-section of the outer end of the screw 1 is a regular dodecagon;
其中，一对螺杆1的外端伸出对应的螺纹套筒8时，一对螺杆1的外端将一对轨道12夹在中部，从而防止盾体10在钢套筒11内旋转。Wherein, when the outer ends of a pair of screw rods 1 protrude from the corresponding threaded sleeves 8 , the outer ends of a pair of screw rods 1 clamp a pair of rails 12 in the middle, thereby preventing the shield body 10 from rotating in the steel sleeve 11 .
在该种技术方案中，螺杆1的材料为42CrMo钢，具有高强度和韧性，中间段为带粗牙螺纹的螺纹杆结构；其通过螺纹牙在螺纹套筒8旋转伸出或缩回，进而伸出盾体10外或缩于盾体10内，伸出盾体10外一端截面为正十二边形。在实际施工过程中，较常见的是：盾体外径直径为6460mm，轨道为P43钢轨；当盾构机套钢筒始发时起到盾体10防扭作用，螺杆1伸出盾体10外约4cm，钢套筒11始发时，螺杆1外端与盾体10外的轨道12的距离保持约2cm，且螺杆与同侧的轨道的边缘平行，使得在盾构机的盾体10发生扭转时，螺杆1外端的正十二边形的一边会与轨道12侧面接触。需要说明的是：螺杆1外端与盾体10外的轨道12的距离保持约2cm，使得盾构机的盾体10最多发生正向或反向的0.5°的扭转后，就会使得螺杆与轨道相抵，从而防止盾体10在钢套筒11内旋转。不管盾体顺时针还是逆时针旋转，一对螺杆中的一个总能起到限位作用，以防止盾体10在钢套筒11内旋转。手动旋转螺杆的内端，使得螺杆的外端伸出或缩回螺纹套筒。In this technical scheme, the material of the screw rod 1 is 42CrMo steel, which has high strength and toughness, and the middle section is a threaded rod structure with a coarse thread; it extends or retracts through the rotation of the threaded teeth on the threaded sleeve 8, and then Extending out of the shield body 10 or shrinking in the shield body 10, the section of one end extending out of the shield body 10 is a regular dodecagon. In the actual construction process, it is more common that: the outer diameter of the shield is 6460mm, and the track is P43 steel rail; About 4cm, when the steel sleeve 11 starts, the distance between the outer end of the screw rod 1 and the rail 12 outside the shield body 10 is kept about 2cm, and the screw rod is parallel to the edge of the rail on the same side, so that the shield body 10 of the shield machine When twisting, one side of the regular dodecagon at the outer end of the screw rod 1 will be in contact with the side of the track 12 . It should be noted that the distance between the outer end of the screw 1 and the rail 12 outside the shield body 10 is kept about 2 cm, so that the shield body 10 of the shield machine is twisted at most forward or reverse by 0.5°, and the screw rod and the shield body 10 will be twisted at most. The rails abut against each other, thereby preventing the shield body 10 from rotating inside the steel sleeve 11 . Regardless of whether the shield body rotates clockwise or counterclockwise, one of the pair of screw rods can always play a limiting role to prevent the shield body 10 from rotating in the steel sleeve 11 . The inner end of the screw is manually rotated so that the outer end of the screw extends or retracts into the threaded sleeve.
在盾构机的盾体10发生扭转时，螺杆1外端的正十二边形的一边会与轨道12侧面接触，轨道12面提供阻力促使盾构机的盾体10不发生扭转；当盾构正常掘进时，螺杆1缩回盾体10内，也是通过旋转螺杆1的内端来调节螺杆1缩回长度。When the shield body 10 of the shield machine is twisted, one side of the regular dodecagon at the outer end of the screw 1 will contact the side of the track 12, and the track 12 provides resistance to prevent the shield body 10 of the shield machine from twisting; when the shield machine During normal excavation, the screw rod 1 retracts into the shield body 10, and the retracted length of the screw rod 1 is also adjusted by rotating the inner end of the screw rod 1.
盾体10，提供防扭装置的支撑作用，其在防扭装置处开有工螺纹套筒8嵌入的通孔。The shield body 10 provides the supporting function of the anti-twist device, and it has a through hole in which the threaded sleeve 8 is embedded at the anti-twist device.

In the groove of the O-ring 9, the first O-ring 9 forms a seal to prevent mud from pouring back into the shield body.
在另一种技术方案中，所述螺纹套筒8与盾体10上对应的通孔之间为过盈配合；In another technical solution, the threaded sleeve 8 is an interference fit with the corresponding through hole on the shield body 10;
所述螺纹套筒8的内端突出于盾体10，并套设有一挡块7，挡块7与盾体10之间绕螺纹套筒8焊接一圈。The inner end of the threaded sleeve 8 protrudes from the shield body 10 and is sleeved with a stopper 7 . The threaded sleeve 8 is welded around the threaded sleeve 8 between the stopper 7 and the shield body 10 .
在该种技术方案中，螺纹套筒8与盾体10上通孔之间为过盈配合，以方便在螺纹套筒8的螺纹失效时，对螺纹套筒8进行更换。挡块7与螺纹套筒8之间也是过盈配合，挡块7与盾体10焊接，可以增加盾体10开通孔附近的强度。比较优选的是，螺纹套筒的凸台是与盾体过盈配合，而螺纹套筒除开凸台的内端与通孔是间隙配合，这样既能保证密封性，又能降低螺纹套筒的安装难度。In this technical solution, the threaded sleeve 8 is an interference fit with the through hole on the shield body 10, so as to facilitate the replacement of the threaded sleeve 8 when the thread of the threaded sleeve 8 fails. There is also an interference fit between the stopper 7 and the threaded sleeve 8, and the stopper 7 is welded to the shield body 10, which can increase the strength near the through hole of the shield body 10. More preferably, the boss of the threaded sleeve is an interference fit with the shield body, and the inner end of the threaded sleeve except the boss is a clearance fit with the through hole, which can not only ensure the sealing performance, but also reduce the friction of the threaded sleeve. Difficulty of installation.
在另一种技术方案中，所述螺杆1的中部内侧由内至外依次螺纹连接有锁紧螺母5、带帽锁紧螺母3；In another technical solution, the inner side of the middle part of the screw rod 1 is threaded with a lock nut 5 and a capped lock nut 3 sequentially from the inside to the outside;
所述锁紧螺母5与两侧的螺纹套筒8、带帽锁紧螺母3均相抵；所述锁紧螺母5与螺纹套筒8之间还设置有第二O形密封圈6；所述锁紧螺母5与锁紧螺母5之间设置有橡胶密封垫4；The lock nut 5 is offset against the threaded sleeve 8 on both sides and the lock nut 3 with a cap; a second O-ring 6 is also arranged between the lock nut 5 and the threaded sleeve 8; the A rubber gasket 4 is arranged between the lock nut 5 and the lock nut 5;
所述带帽锁紧螺母3远离锁紧螺母5的内端设置有封闭盖帽，其将所述螺杆1的内端包裹在内。The inner end of the capped lock nut 3 away from the lock nut 5 is provided with a closed cap, which wraps the inner end of the screw rod 1 inside.
在该种技术方案中，钢套筒11始发时，仅凸台端面安装有凸台端面O形密封圈9；盾构机在土体中正常掘进时，在装上锁紧螺母55时，纵向端面安装有第二道端面O形密封圈6，起到二次密封的作用，以防止泥浆倒灌进入盾体。拧紧带帽锁紧螺母3时，可以采用一个扳手使得锁紧螺母5不动，然后再拧紧带帽锁紧螺母3，设置两个螺母一是可以防松动，二是加强密封作用，三是防止操作人员误操作，将螺杆拧出螺纹套筒或拧松。In this technical solution, when the steel sleeve 11 is started, only the O-ring 9 on the end face of the boss is installed on the end face of the boss; A second end face O-ring 6 is installed on the longitudinal end face, which acts as a secondary seal to prevent mud from pouring back into the shield body. When tightening the capped lock nut 3, a wrench can be used to make the lock nut 5 immobile, and then tighten the capped lock nut 3. Two nuts are provided to prevent loosening, to strengthen the sealing effect, and to prevent The operator misuses the screw rod out of the threaded sleeve or loosens it.
在另一种技术方案中，所述螺杆1的中部螺纹上缠绕有一圈生胶带2。In another technical solution, a circle of raw tape 2 is wound on the middle thread of the screw 1 .
在该种技术方案中，生胶带2进一步加强密封，以防止泥浆倒灌进入盾体10In this technical solution, the raw tape 2 further strengthens the seal to prevent the mud from pouring back into the shield body 10
在另一种技术方案中，所述螺杆1的内端的截面为正六边形。In another technical solution, the cross section of the inner end of the screw 1 is a regular hexagon.
在该种技术方案中，所述螺杆1的内端的截面为正六边形方便与六角套筒扳手配合使用，比直接手动拧螺杆1要省时省力。In this technical solution, the cross-section of the inner end of the screw 1 is a regular hexagon, which is convenient for use with a hexagonal socket wrench, and saves time and labor compared with directly screwing the screw 1 manually.
