Pin splitter applied to narrow space and using method thereof

Abstract

The invention discloses a pin splitter applied to narrow space and a using method thereof, and belongs to the technical field of handheld special fastening tools. The pin splitter comprises a coaxial positioning sleeve, a pin splitting firing pin mechanism, a handheld probe and a bolt lantern ring positioning rod, and the handheld probe comprises a handle, a sliding groove base, an opening clamping ring, a positioning rod inserting hole, a firing pin guiding sliding groove, a firing pin pull rod through hole and a sleeve inserting hole. The pin splitter applied to the narrow space is suitable for the special situations that due to the fact that the diameter of a round pipe component A is too small, conventional tools and visual fields are limited, and pin splitting operation lacks necessary operation space, the operation process can be greatly simplified, the pin splitting quality and the acceptance efficiency can be enhanced, meanwhile, the operation difficulty is effectively reduced, and the risks that an operator is scratched, injured by a crashing object or sprained and the like are avoided.

Description

Technical field[0001]The present invention belongs to the technical field of hand-held special fastening tools, and more particularly to a smaller pin that is applied to a narrow space and its use.Background technique[0002]Track passenger cars such as high-speed rail involve a large number of complex and special fasteners mounting structures, one of the structural and methods of use of bolt fasteners such asfigure 1 withfigure 2 As shown, the front section of the bolt member 1 is provided with a radial pin through hole 1-1, and a multi-set radial latch card slot 2-1 is provided on the front end surface of the fastening nut 2. The anti-pine pin 3 includes an integral type C-type half-ring terminal 3-1 and two of the two tabular pin rods 3-2, and the initial pitch value of the two pin rods 3-2 formed by extending the C-type open end. K. The distance from the front end surface of the bolts 1-1 to the bolts 1 is T.[0003]When the application is applied, the bolt member 1 is mounted on th...

Problems solved by technology

[0007] In order to solve the existing problem that the diameter of the round pipe part A is too small, even with one hand, the maintenance personnel do not have enough space for turning and operating, and use conventional tools such as wrench and pliers to smoothly insert the new anti-loosening pin that needs to be replaced at one time. In the bolt through hole deep in the inner cavity of the round tube part A, it is more difficult to insert fingers into the narrow inner cavity of the round tube part A, and reversely split the front end of the plug rod to both sides and bend and form the required new Due to the lack of convenient and flexible operating tools in the replacement process of anti-loosening bolts, the operation process is time-consuming, laborious, and inefficient; at the same time, due to the poor construction conditions of some maintenance plants, they do not have appropriate or sufficient trenches As a result, maintenance personnel often need to drill under the narrow car body in an unnatural side lying position, and observe the port of the round tube part A and its inner cavity structure smoothly with a slightly upward posture of the head and neck, which often leads to maintenance People scratch their fingers due to limited vision, or their faces are injured by tools such as wrenches and iron rulers that slip out of their hands due to difficulty in applying force, or the bending section of the anti-loosening bolt is not bent in place, and the arc cannot meet the acceptance standard , which not only affects the production efficiency and quality of maintenance work, but also increases the technical problem of potential safety hazards for operators. The invention provides a splitter for narrow spaces and its use method
