Embodiment Construction
[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0027] as attached figure 2 to attach Figure 7 As shown, in order to achieve the above purpose, the technical solution adopted by the present invention is: it includes an assembly machine main body 1 and a balance beam detachably connected to the assembly machine main body 1 at one end.
[0028] The balance beam includes a pipe 3 detachably connected to the assembly machine body 1 at one end, and at least two connecting pieces 5 connected to the pipe 3 rotatably around the axis of the pipe 3 and used to connect with the shuttle cabin 4 .
[0029] A through hole matched with the pipe fitting 3 is opened on the connecting piece 5, the c...

The invention discloses a shuttle cabin lifting device used on the saturated condition with pressure. The shuttle cabin lifting device comprises an erector body and a balance beam, wherein one end of the balance beam is detachably connected to the erector body. The balance beam comprises a pipe fitting and at least two connecting parts, wherein one end of the pipe fitting is detachably connected with the erector body, the two connecting parts are connected to the pipe fitting by rotating around the axis of the pipe fitting, and the two connecting parts are used for being connected with a shuttle cabin. A pipe piece grabbing and lifting device on an existing erector body is dismantled. By the adoption of the technical scheme, according to the shuttle cabin lifting device used on the saturated condition with pressure, the erector in the prior art is refitted, the pipe piece grabbing and lifting device on the existing erector body is dismantled, the balance beam is added, and the balance beam plays the roles in reducing horizontal pressure borne by a lifting appliance, avoiding damage to the shuttle cabin and improving lifting appliance safety factors in the cabin lifting process. After tool changing operation is finished, the balance beam can be dismantled, and secondary installation and use of the pipe piece grabbing and lifting device are not affected.
Description
technical field [0001] The invention relates to a hoisting device for a shuttle cabin under saturated and pressurized conditions, belonging to the field of shield tunneling. Background technique [0002] With the rapid development of my country's urban underground rail transit construction, the shield construction method has become increasingly mature and has been applied to many tunnel projects; however, it is also faced with the influence of many factors such as complex geological conditions, harsh operating environments, and high construction risks, especially for Cross-river and sea-crossing tunnel projects with complex geological conditions such as long distances, large diameters, high water pressure, and complex sections. For the construction of such a tunnel project, the management of the cutting tool is particularly important, and it is necessary to enter the cabin to replace the cutting tool when necessary. At present, the opening operation mainly consists of the fo...
