Description
Technical Field
The utility model relates to a shield constructs quick-witted equipment field, concretely designs a shield constructs quick-witted section of jurisdiction frock.
Background
Shield tunnel boring machine, shield machine for short. Is a special engineering machine for tunneling. The shield segment is a main assembly component for shield machine construction, is an outermost shield of a tunnel, plays a role in resisting soil layer pressure, underground water pressure and some special loads, and has important issues concerned by domestic and foreign shield companies for quality safety. Therefore, the steel duct piece is designed, is suitable for 6-7 m series shield machines, achieves the purpose of testing different loads in the debugging process of the erector by increasing and decreasing the balancing weights, improves the working efficiency and ensures the personnel and property safety in the debugging process.
The shield constructs the machine at workshop final assembly debugging in-process, and the debugging personnel need to snatch the cement section of jurisdiction and carry out load test when carrying out the erector action test, has the phenomenon that the section of jurisdiction slightly rocked often in this action test in-process, need to break the debugging process and carry out detailed investigation to the cement section of jurisdiction for the erector and debugging. The reason that slight shaking occurs in the grabbing and lifting process is found through inspection to be that the thread clearance between the segment bolt and the segment is too large, and the segment bolt are caused by relative movement in the grabbing and lifting process.
The cement segment that the debugging of shield constructs the machine and adopts is unanimous with the segment when the tunnel was built, and the screw thread of this type of segment hoist and mount adopts engineering plastics preparation, only needs once to assemble in the use, does not exist when assembling and rocks the phenomenon. The phenomenon that the pipe piece is slightly shaken in the grabbing and lifting process is caused by the fact that the existing pipe piece is deformed due to the fact that the threads for hoisting are used for multiple times and the pipe piece is abraded too much to lose the fastening effect. Thereby influencing normal equipment debugging work and causing potential safety hazards of property personnel.
According to analysis, the segment is hidden safely in the following situations: unqualified manufacturing process, unreasonable storage position and long-term use. And the section of jurisdiction that the debugging process goes wrong has the phenomenon of long-term use, and the section of jurisdiction generally uses fork truck to go on when handling, and does not adopt special fixture, and the section of jurisdiction bumps the phenomenon and takes place occasionally, leads to the outward appearance of section of jurisdiction impaired. The hoisting threaded hole of the cement segment is deformed due to abrasion caused by long-term use, the fastening effect is lost, a plurality of parts are damaged by collision, and the potential safety hazard is not small.
The utility model has the following contents:
not enough to prior art, the utility model provides a shield constructs quick-witted section of jurisdiction frock that convenient, the firm damage of installation of unloading takes place to drop is installed to installing and removing.
The utility model discloses the technical problem that will solve adopts following technical scheme to realize:
a shield machine pipe sheet tool comprises a steel pipe sheet, a lifting baffle, a bearing block and a bearing bolt strip;
the steel pipe piece comprises a bottom arc plate, a transverse arc plate and a lateral partition plate, wherein the transverse arc plate and the lateral partition plate are arranged on the bottom arc plate and enclose a plurality of bearing grooves; the middle of the bottom arc plate is provided with a threaded base; a plurality of fixing holes are formed in the lateral partition plate;
the bearing block is arranged in the bearing groove, and a plurality of bearing holes which penetrate through the bearing block and correspond to the fixing holes are formed in the bearing block;
the lifting baffle is provided with a lifting hole matched with the threaded base and is arranged on the steel pipe sheet;
the bearing bolt strip passes through the bearing hole and the fixing hole.
As an optimization of the utility model, the quantity of bearing groove is 12.
As an optimization of the utility model, the one end of bearing gib is provided with increase portion, and the other end sets up the nut.
The utility model provides a pair of shield constructs quick-witted section of jurisdiction frock, it has following beneficial effect:
