Description
Technical Field
The utility model relates to the technical field of shield machines, in particular to a shield segment quick installation assembly head.
Background
The existing pipe segment assembling head is a main bearing part for pipe segment transportation and installation, the hoisting head is screwed into a prefabricated hoisting hole of the pipe segment before hoisting, then the clamping part of the transportation equipment is connected with the clamping section of the assembling head, pipe segment hoisting is achieved, the existing hoisting head comprises a bolt section and a clamping section, in order to ensure that the pipe segment does not shake in the process of pipe segment transportation and installation, threads of the bolt section of the assembling head are required to be tightly connected with threads of a grouting pipe in the hoisting hole, interference fit is generally adopted, in addition, the process is usually difficult to screw into the hoisting hole by using a manual wrench and pipe tongs, manual tightening is difficult, in addition, the assembling head cannot be screwed in place completely due to partial matching errors, the problem that the drawing force is insufficient and the pipe segment shakes easily in the hoisting process, the assembling error table or the pipe segment falls down is caused, and the construction process and the construction quality are seriously influenced.
Disclosure of Invention
The utility model aims to provide a shield segment quick installation assembly head so as to solve the problems in the background technology.
The technical scheme of the utility model is as follows: the shield segment quick installation assembly head comprises a bolt segment and further comprises a bolt segment;
the clamping section is fixed on the outer wall of the bottom of the bolt section, and the outer wall of the bottom of the clamping section is provided with a universal outer hexagonal head fastener.
Preferably, a national standard socket wrench is arranged below the universal type external hexagonal head fastener, and the national standard socket wrench is matched with the universal type external hexagonal head fastener.
Preferably, the outer wall of the top of the bolt section is provided with an exhaust and drainage hole, and the other end of the exhaust and drainage hole extends to one side of the clamping section.
Preferably, the bolt section and the clamping section are made of 42 CrMo.
The utility model provides a shield segment rapid installation assembly head through improvement, which has the following improvement and advantages compared with the prior art:
according to the utility model, the original hoisting head structure is changed, and the pipe piece assembling head is assembled and disassembled in a hexagonal mode through an electric wrench or a national standard socket wrench, so that the assembling head is ensured to be assembled in place; and save manual power in installation, dismantlement in-process, realize effectually to shield structure machine pipe piece installation shaping, section of jurisdiction transport, vertical hoisting process, solved conventional section of jurisdiction hoist and mount and caused unable installation in place because of manual installation, the section of jurisdiction drops, safety risks such as section of jurisdiction damage, the security improves by a wide margin.
Drawings
The utility model is further explained below with reference to the drawings and examples:
fig. 1 is a schematic structural view of the present utility model.
Reference numerals illustrate:
1. a bolt section; 2. an exhaust drain hole; 3. a clamping section; 4. a universal external hex head fastener; 5. national standard socket wrench.
Detailed Description
The following detailed description of the present utility model clearly and fully describes the technical solutions of the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides a shield segment quick installation assembly head through improvement, which comprises the following steps:
as shown in FIG. 1, the shield segment quick installation assembly head comprises a bolt segment 1 and further comprises;
the clamping section 3, the clamping section 3 is fixed on the outer wall of the bottom of the bolt section 1, and the universal outer hexagonal head fastener 4 is installed on the outer wall of the bottom of the clamping section 3.
Further, the national standard socket spanner 5 is arranged below the universal type external hexagonal head fastening piece 4, the national standard socket spanner 5 is matched with the universal type external hexagonal head fastening piece 4, when the assembly head is installed, the national standard socket spanner 5 or the universal type air cannon can be used for installing the hoisting head through the external hexagonal structure, the manual installation is omitted, and the installation is convenient, safe and quick.
Further, the outer wall of the top of the bolt section 1 is provided with the air exhaust and drainage hole 2, the other end of the air exhaust and drainage hole 2 extends to one side of the clamping section 3, air and water inside the thread groove can be discharged to the outside during installation, and the assembly head can be locked completely.
Further, the bolt section 1 and the clamping section 3 are made of 42CrMo, and the 42CrMo material is subjected to heat treatment to improve the strength and the rigidity.
Working principle: through redesigning at joint section 3, general outer hexagonal type head fastener 4 uses outer hexagonal shape device, when the installation is assembled the head, can use national standard socket spanner 5 or general wind big gun to install the hoist and mount head through outer hexagonal structure, more save the manpower installation, and convenient, safety, swiftly install, and the head of assembling adopts 42CrMo material to improve intensity and rigidity through heat treatment, the section of jurisdiction has been realized directly screwing, the process that the head was wasted time and energy is assembled in the manual installation has been avoided, can be more convenient and quick hoist and mount, reduce manufacturing cost and the complexity of operation, and be provided with exhaust and drainage hole 2 on bolt section 1 and the joint section 3, can be with the inside air of screw groove and water row to the external world when installing, can make the assembly head can lock completely.
