The utility model relates to an ann of shield constructs quick-witted articulated hydro-cylinder round pin and tears frock open has avoided the articulated hydro-cylinder round pin to need the problem that the supplementary and setting up interim hangers of great multiplexer utensil at the installation or demolish the in-process, and is simple high-efficient, and the frock is the bolt fastening, satisfies repetitious usage requirement many times.
Description
Technical Field
The utility model relates to an ann of shield constructs quick-witted articulated hydro-cylinder round pin and tears frock open.
Background
The installation and disassembly of the hinged oil cylinder pin are generally carried out along with the maintenance of a hinged system of the shield machine, particularly, the replacement of a hinged seal is involved when the maintenance of the hinged system is carried out, the process comprises the separation of a middle shield and a hinged ring, the hinged oil cylinder pin needs to be pulled out from a joint bearing of an oil cylinder rod head, and the common pulling-out modes comprise three working modes of hammering out, jacking out and pulling out.
The hammering-out and the jacking-off working principle are similar, common tools such as a hammer and a jack are respectively used for direct dismounting, when an oil cylinder pin which is seriously blocked is encountered, the dismounting or mounting efficiency is low and the difficulty is high due to the influence of space limitation and uneven stress. The working mode of pulling out is to make a temporary lug on site to be a fixed point and to hang the center of the oil cylinder pin by using the chain guide hoist to pull out, the fixed point of the lug needs to be selected, the stress direction and the center of the pin shaft are ensured to be on the same straight line, and the working mode has higher requirement on the working space and higher implementation difficulty as the former two working modes.
Fig. 1 is a state of a hinge cylinder pin inserted into a joint bearing of a cylinder head in the prior art, in which the cylinder head extends between two positioning pin bases, the hinge cylinder pin sequentially passes through the positioning pin bases and the joint bearing of the cylinder head, and the two positioning pin bases are welded on a middle shield cylinder assembly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an ann tears frock open for shield constructs quick-witted articulated hydro-cylinder round pin aims at solving above-mentioned problem.
In order to realize the above-mentioned purpose, the technical scheme of the utility model design 1, an ann who is used for shield structure machine articulated cylinder round pin tears frock open, its characterized in that: the tool comprises a tool main body, a full-thread stud and an oil cylinder pin connecting seat; the appearance of the tool main body is U-shaped; two feet at the lower part of the tool main body are screwed on the positioning pin base, so that the center of a beam at the upper part of the tool main body is just above the hinge oil cylinder pin; a screw hole for screwing a full-thread stud is formed in the center of the beam at the upper part of the tool main body; the lower end of the full-thread stud is connected with an oil cylinder pin connecting seat; the oil cylinder pin connecting seat is connected with the hinged oil cylinder pin.
Furthermore, a hexagon nut used for being pulled by a wrench is arranged at the upper end of the full-thread stud.
Further, the oil cylinder pin connecting seat is sheet-shaped, a plurality of screw holes are formed in the oil cylinder pin connecting seat, and the oil cylinder pin connecting seat is connected with the lower end of the full-thread stud and the hinged oil cylinder pin in a threaded connection mode respectively.
The using method comprises the following steps: the hinged oil cylinder pin is inserted into or pulled out of the oil cylinder rod head by screwing the full-thread stud.
The utility model has the advantages and the beneficial effects that: the utility model relates to an ann of shield constructs quick-witted articulated hydro-cylinder round pin and tears frock open has avoided the articulated hydro-cylinder round pin to need the problem that the supplementary and setting up interim hangers of great multiplexer utensil at the installation or demolish the in-process, and is simple high-efficient, and the frock is the bolt fastening, satisfies repetitious usage requirement many times.
