Externally-hung channel connecting piece

Abstract

The invention discloses an externally-hung channel connecting piece. The externally-hung channel connecting piece involves a connecting piece main body, extruding plates, correcting cavities, a mounting channel and operating cavities, wherein the bottom end of the connecting piece main body is provided with the mounting channel, the extruding plates are arranged on the two sides of the interior ofthe mounting channel correspondingly, hinged seats are fixed on the parts, at one sides of the extruding plates, of the inner wall of the connecting piece main body, a limiting channel is formed in the top end of the connecting piece main body, the correcting cavities are formed in the two sides of the limiting groove correspondingly, a hanging opening is formed in the side, far away from the mounting channel, of the connecting piece main body, an anti-deflecting channel is formed in the part, at one side of the hanging opening, of the surface of the connecting piece main body, and equal-spacing compressing springs are arranged on the inner walls of the two sides of the anti-deflecting channel. According to the externally-hung channel connecting piece, the correcting work during T-shapedbolt penetrating and inserting is realized, the phenomenon that the externally-hung channel connecting piece is loosened during limiting is avoided, the deflection phenomenon of the externally-hung channel connecting piece when being hung is avoided, and the safety of the externally-hung channel connecting piece during use is increased.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an external hanging channel connector. Background technique [0002] With the development of the rail transit industry, the channels have been widely used. Usually, a series of problems will be found in the application process of the channels, such as load bearing problems, service life problems, maintenance and replacement problems, etc. For maintenance and replacement, Many people use pre-embedded stainless steel sleeves, but most of the general sleeves are made of stainless steel, and there are many problems: one is the problem of thread damage. Due to the nature of the stainless steel material itself, the thread strength is not high and it is easy to damage. Moreover, once damaged, the sleeve cannot be repaired because the sleeve is pre-embedded in the concrete; the second is the problem of anti-loosening. There is no effective anti-loosening mechanism, and it cannot be ...

Problems solved by technology

[0002] With the development of the rail transit industry, the channels have been widely used. Usually, a series of problems will be found in the application process of the channels, such as load bearing problems, service life problems, maintenance and replacement problems, etc. For maintenance and replacement, Many people use pre-embedded stainless steel sleeves, but most of the general sleeves are made of stainless steel, and there are many problems: one is the problem of thread damage. Due to the nature of the stainless steel material itself, the thread strength is not high and it is easy to damage. Moreover, once damaged, the sleeve cannot be repaired because the sleeve is pre-embedded in the concrete; the second is the problem of anti-loosening. There is no effective anti-loosening mechanism, and it cannot be guaranteed not to loosen during operation. Therefore, it is often necessary to use an external channel when laying the channel. connector

[0003] There are many kinds of such external channel connectors on the market today, which can basically meet people's needs, but there are still some problems. The specific problems are as follows: First, the traditional external channel connectors are inserted through T-bolt Corrective work is seldom set up, which can easily lead to loosening of the external hanging channel connector when it is limited; secondly, the traditional external hanging channel connecting piece is prone to sliding and loosening during use; thirdly, the traditional external hanging channel The firmness of the channel connector is poor when connected, which seriously affects the safety of the external channel connector in use
