Description

Installation device, application and method for cap-shaped beam hanging bolt Technical Field The invention relates to the field of mechanical tools, in particular to a mounting device, application and method for a hat-shaped beam hanging bolt. Background The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. The hat-shaped beam is a girder commonly used in railway vehicles such as power vehicles, and large-scale key equipment at the bottom of the vehicle is generally fixed on a hat-shaped beam guide rail through hanging bolts. Because the hat Liang Caizhi is different from the hanging bolt, the special zinc chromate resin primer is generally required to prevent the formation of a primary cell when the dissimilar metals are in fixed contact, and the inside of the hat beam is coated with the special zinc chromate resin primer. Referring to fig. 1, a door-shaped section is arranged at the bottom of a cap-shaped beam 2, a cap-shaped beam guide rail 14 is arranged in the door-shaped section, when a hanging bolt 1 is installed, the hanging bolt needs to enter through the end part of the cap-shaped beam guide rail 14, and then manually moves to a corresponding installation position, and the inventor finds that the following problems exist in the installation process of the hanging bolt: the hanging bolt is manually moved, so that the moving speed is low; the zinc chromate special resin primer on the inner surface of the cap-shaped beam guide rail is extremely easy to damage in the moving process of the hanging bolt, and because the zinc chromate special resin primer is arranged in the cap-shaped beam, the observation is relatively difficult and complex, the damaged part is difficult to find, and if damage occurs, the repair is difficult because of the narrow operation space. The term explains that electrochemical corrosion, also called contact corrosion or bimetallic corrosion, caused by contact of two or more metals with different electrode potentials in a corrosive medium requires spraying of a special resin primer of zinc chromate. Disclosure of Invention Aiming at the defects existing in the prior art, the first object of the invention is to provide a mounting device for a cap-shaped beam hanging bolt, which solves the problem that the zinc chromate special resin primer is easy to be damaged by the cap-shaped beam mounting hanging bolt, and improves the mounting efficiency of the hanging bolt. The second object of the invention is to provide an application of the installation device for the hat-shaped beam hanging bolt, which can be applied to the installation of railway vehicle bottom equipment. The third object of the invention is to provide a method for installing the bottom equipment of the railway vehicle, which is convenient for the movement of the hanging bolts and improves the installation efficiency of the bottom equipment. In order to achieve the above object, the present invention is realized by the following technical scheme: The utility model provides a cap type roof beam installation device for suspension bolt, including first support piece and second support piece, first support piece sets up with the second support piece is relative and one side swing joint of two, so that at least one of them is rotatable for another, first support piece, second support piece set up moving part respectively, moving part can be with cap type roof beam surface contact, external force promotes first support piece, second support piece and moves along cap type roof beam guide rail place section length direction, first support piece, second support piece's opposite side sets up clamping part respectively, two clamping part centre gripping suspension bolt's screw rod and make suspension bolt keep suspended state for the cap type roof beam. According to the mounting device, the first supporting piece is movably connected with the second supporting piece, one supporting piece can be connected with the hat-shaped beam in a hanging mode after rotating relative to the other supporting piece, the clamping component clamps the hat-shaped beam and can enable the hanging bolt not to be in contact with the hat-shaped beam, the first supporting piece and the second supporting piece are pushed by external force, the hanging bolt can be driven to rapidly move along the section where the hat-shaped beam guide rail is located under the action of the moving component, and zinc chromate special resin primer is effectively prevented from being damaged by collision in the moving process of the hanging bolt. According to the mounting device for the hat-shaped beam hanging bolt, the first supporting piece and the bottom side of the second supporting piece are hinged, so that at least one of the first supporting piece or the second supporting piece can rotate relative to the other, and the mounting device is conveniently arranged on the hat-shap
