技术领域technical field
本实用新型属于建筑施工领域,特别涉及一种盾构机下井吊装过程中可调节盾构机部件姿态的吊钩。The utility model belongs to the field of building construction, in particular to a hook capable of adjusting the posture of shield machine parts during the hoisting process of a shield machine in a well.
背景技术Background technique
目前各大城市都已在建或者拟建地铁项目,盾构机是各施工单位作为隧道区间掘进的首选设备,但盾构机体型较大,下井及出井非常困难,并耗费大量人力、财力、物力,稍有问题就会影响工期。如何提高盾构机下井及安装效率对地铁建设具有重要的意义。At present, subway projects are under construction or planned in major cities. The shield machine is the preferred equipment for tunnel excavation by various construction units. However, the shield machine is large in size, and it is very difficult to go down and out of the well, and it consumes a lot of manpower, financial resources, and resources. Material resources, a slight problem will affect the construction period. How to improve the efficiency of shield tunneling and installation is of great significance to subway construction.
在吊装盾构机时,传统的挂钩是一个固定的部件,不能调整长度。在吊装盾构机部件时,盾构孔位对盾构部件在井下的姿态要求比较严格,如果姿态偏差较大,会导致相邻盾构机部件的连接螺栓无法顺利安装。另外,盾构机部件尺寸和重量均较大,在井底轨道上对其进行人工纠偏调节非常困难。When hoisting the shield machine, the traditional hook is a fixed part, and the length cannot be adjusted. When hoisting the shield machine components, the position of the shield hole has strict requirements on the attitude of the shield machine components in the underground. If the attitude deviation is large, the connecting bolts of the adjacent shield machine components will not be installed smoothly. In addition, the size and weight of shield machine components are relatively large, and it is very difficult to manually adjust them on the bottom track.
传统的安装方法是起吊前尽量保证吊耳位置精密、准确,但由于吊绳及吊钩的尺寸及起吊过程中绳索受力变形的不均匀和温差引起绳索长度变化的差异,会导致盾构机下到井底后与相邻部件间存在一定的对正偏差,从而导致组装连接困难。The traditional installation method is to ensure that the position of the lifting lug is precise and accurate before lifting. However, due to the size of the lifting rope and hook, the uneven stress and deformation of the rope during the lifting process, and the difference in the length of the rope caused by the temperature difference, the shield machine will After going down to the bottom of the well, there is a certain alignment deviation with the adjacent components, which leads to difficulties in assembly and connection.
发明内容Contents of the invention

The hook is simple in structure, easy to operate, and can realize shield The small adjustment of the attitude of the machine parts avoids the deviation of the bolt hole positions between the parts of the shield machine and improves the efficiency of shield machine assembly.
如上构思,本实用新型的技术方案是:一种盾构机下井吊装过程中可调节盾构机部件姿态的吊钩,其特征在于:在安装架上垂直固装一螺杆,螺杆与安装架上部的连接位置安装顶部紧固螺母,螺杆与安装架下部的连接位置安装底部紧固螺母,并且螺杆顶部制有连接钢索的吊环;所述安装架上开有用于连接螺栓的预留孔。As conceived above, the technical solution of the present utility model is: a hook that can adjust the attitude of the shield machine parts during the hoisting process of the shield machine. The top fastening nut is installed at the connecting position, the bottom fastening nut is installed at the connecting position between the screw rod and the lower part of the mounting frame, and the top of the screw rod is formed with a ring for connecting the steel cable; the mounting frame is provided with reserved holes for connecting bolts.
上述安装架为“n”形。Above-mentioned mounting frame is "n" shape.
本实用新型具有如下的优点和积极效果:The utility model has the following advantages and positive effects:
1、本实用新型通过调整顶部紧固螺母和底部紧固螺母,来调整挂钩长度,从而来调整盾构机的下井姿态,避免盾构机部件间螺栓孔位的偏差,以达到与井下其他盾构机部件的准确连接,提高盾构组装效率。1. The utility model adjusts the length of the hook by adjusting the top fastening nut and the bottom fastening nut, thereby adjusting the downhole posture of the shield machine, avoiding the deviation of the bolt hole position between the shield machine parts, so as to achieve the same level as other shields in the well. The accurate connection of machine parts improves the efficiency of shield assembly.

具体实施方式Detailed ways
以下结合附图对本实用新型做进一步描述。Below in conjunction with accompanying drawing, the utility model is further described.
如图1所示:一种盾构机下井吊装过程中可调节盾构机部件姿态的吊钩,在“n”形安装架6上垂直固装一螺杆4,螺杆与安装架上部的连接位置安装顶部紧固螺母2,螺杆与安装架下部的连接位置安装底部紧固螺母3,并且螺杆顶部制有连接钢索的吊环1;所述安装架上开有用于连接螺栓的预留孔5。As shown in Figure 1: a hook that can adjust the posture of the shield machine parts during the hoisting process of the shield machine. A screw 4 is vertically fixed on the "n"-shaped mounting frame 6, and the connection position between the screw and the upper part of the mounting frame The top fastening nut 2 is installed, the bottom fastening nut 3 is installed at the connecting position of the screw rod and the bottom of the mounting frame, and the top of the screw rod is shaped on the suspension ring 1 connecting the cable; the mounting frame has a reserved hole 5 for connecting the bolts.
如图2所示,盾构机部件吊耳7、8、9、10的位置尽量做到精确,但在安装及吊装过程中往往会存在一定的误差,导致盾构机起吊部件与井下部件之间的连接比较困难,相邻部件间的连接螺栓孔位对不齐。而盾构机部件又十分笨拙,在井底用人工的方法进行姿态调整费时费力效果较差,因此可以根据误差情况对挂钩进行调节,以减小姿态错位,为顺利连接盾构机提供条件。As shown in Figure 2, the positions of the lifting lugs 7, 8, 9, and 10 of the shield machine parts should be as accurate as possible, but there are often certain errors in the installation and hoisting process, resulting in the gap between the lifting parts of the shield machine and the underground parts. The connection between them is difficult, and the connecting bolt holes between adjacent parts are not aligned. The parts of the shield machine are very clumsy, and manual attitude adjustment at the bottom of the well is time-consuming and laborious, and the effect is poor. Therefore, the hook can be adjusted according to the error situation to reduce the attitude misalignment and provide conditions for the smooth connection of the shield machine.
假设盾构机9、10点所在的右半部分偏低,可同时调整连接在9、10吊耳上的可调吊环,使盾构机构件右半部分小幅度上升,直到位置合适为止。Assuming that the right half of the shield machine where points 9 and 10 are located is low, the adjustable lifting rings connected to the lifting lugs of 9 and 10 can be adjusted at the same time to make the right half of the shield machine components rise slightly until the position is appropriate.
首先降低吊环,使吊绳处于不受力状态以便对吊钩进行调节,用扳手将顶部紧固螺母2向上旋松,将底部紧固螺母3往上旋紧,从而小幅缩减了吊钩长度,然后拧紧顶部紧固螺母2。缓慢提升吊钩,直至盾构机部件完全被吊起,由于小幅减小了9、10位置处的吊钩的长度,使盾构机右侧部分得到了提升,调整了盾构机的姿态,直至盾构机部件姿态满足安装要求。First, lower the lifting ring so that the lifting rope is in an unstressed state to adjust the hook. Use a wrench to loosen the top fastening nut 2 upwards, and tighten the bottom fastening nut 3 upwards, thereby reducing the length of the hook slightly. Then tighten the top fastening nut 2. Slowly raise the hook until the parts of the shield machine are completely hoisted. Since the length of the hooks at positions 9 and 10 is slightly reduced, the right part of the shield machine is lifted, and the posture of the shield machine is adjusted. Until the posture of the shield machine components meets the installation requirements.
本实用新型加工容易、操作简单、小范围内可有效调整盾构机部件的姿态,以满足设备安装的要求、提高安装效率。The utility model has the advantages of easy processing and simple operation, and can effectively adjust the posture of the parts of the shield machine in a small range, so as to meet the requirements of equipment installation and improve the installation efficiency.
