An anti-loose anti-skid channel and its installation and connection device

Abstract

The invention discloses a channel with anti-loosening and anti-slip functions and its installation and connection device, which consists of a channel (1), a special bolt for the channel (2), an anti-loosening and anti-slip pad (3), and an installed and connected device. The workpiece (d) is composed. The channel (1) has continuous and evenly distributed serrations 5 on the outer surface of the opening; the pad (3) has serrations 4 matching the outer surface serrations 5 of the channel (1) on both sides of the pad (3). There is a downward clip hook 1; the T-shaped head of the bolt (2) is put into the inner groove of the channel (1), the head 2 hooks the inner hook 3 of the channel (1), and the clamp pad (3) passes through The shank portion of the bolt (two), its tooth surface 4 and the teeth 5 on the outer surface 6 of the groove are engaged, and the clip hook 1 clamps and hooks the head 2 of the bolt (two). The bolt (2) passing through the clip (3) will not move (slide) along the length of the channel under load, which is convenient for the pre-precise positioning of the bolt (2) before the workpiece (4) is installed and during use. The installation connection is more stable and reliable; the whole positioning and locking are stable and reliable, easy to operate, no special tools and accessories are required, and can be reused, with excellent economy.

Description

technical field [0001] The invention relates to a channel used for installing components such as contact nets and pipelines, and has anti-loosening and anti-slip channels along the length direction of the channel, which is composed of a channel body, special T-shaped bolts and clamping pads. Due to the anti-loosening function, the stability, positioning accuracy and reliability of the installation connection are significantly improved. Due to the anti-slip function, it is especially suitable for vertically arranged channels. It is mainly used for the fixed installation of railway catenary, engineering pipelines and other accessories, building external parts, etc. Background technique [0002] The channel is arranged along the installation line and has a T-shaped inner groove, which is similar to an extended T-shaped groove. With special T-shaped bolts, the workpiece can be installed and connected on the outer surface of the channel. Most of the channels are made of ordinary...

Problems solved by technology

[0003] Because the existing channel has the same section along the length direction, such as the existing utility model patent "A Hot-rolled Channel Steel" patent No. ZL200820108272.3, after the channel is installed and connected, due to stress changes and vibration environments during use, It is easy to cause loose connection, and the stability and reliability of use are extremely limited; at the same time, the length direction is completely fastened by the friction force after bolt connection, lack of reliable locking, and it is easy to move, especially for vertical channels such as building external hanging. In the state of arrangement, the initial installation and positioning are not easy, and slippage is very easy to occur during use. At present, the method of welding and locking after installation has to be adopted, which is difficult to operate and expensive.

Although there is a groove with teeth inside the groove, such as the published invention patent "Anchor device for grooved parts for construction industry" patent application number 200710045762.3, and the existing utility model patent "A pre-buried connection system with tooth groove 》Patent No. ZL200820043743.7, but it needs to be used with the same special bolt with teeth, which has a certain anti-loosening function. Once the bolt is loose, the positioning function of the tooth groove is greatly weakened or even completely lost, and the installation and connection position will also move.

Also, when the channel is set vertically, the T-bolt positioning cannot be separated from the hand, and the external compression nut must be tightened, which brings difficulties to the pre-precise positioning and installation of the workpiece
