Problems solved by technology

[0005] The object of the present invention is to provide an integrally formed stainless steel cable bridge and its preparation method, to solve the problem that the existing cable bridge proposed in the above background technology needs to go through processes such as material selection, cutting, grinding, welding and assembling. It is cumbersome, and solder joints are easy to appear in the welding assembly, the degree of integration is low, and the compactness cannot be guaranteed. The cable tray using stainless steel as raw material, because stainless steel has certain ductility, strength and toughness are not high, subject to Local subsidence and loose connection will occur after the force is applied. Secondly, in the face of fire, the heating of the cable bridge under high temperature will cause the internal cable to overheat and burn from time to time, which has long become a problem of economic waste and safety of information transmission.

preparation example Construction

[0026] The invention provides an integrally formed stainless steel cable tray and its preparation method, which can increase the processing speed, increase the strength and toughness, and have flame retardancy. Please refer to Figure 1-6 , including a bottom plate 100, a left flap 200, a right flap 300, a left mounting plate 400 and a right mounting plate 500;

[0027] see again Figure 5 , the interior of the bottom plate 100 has a top backing plate 110, specifically, the bottom of the top backing plate 110 is bonded with a compression plate 111, the bottom of the compression plate 111 is bonded with a bottom backing plate 112, and the material of the compression plate 111 is expanded graphite powder;

[0028] see again Figure 1-3 , the bottom of the left flap 200 and the left side wall of the bottom plate 100 are fixedly installed. Specifically, the left side wall of the bottom plate 100 is integrally formed to connect with the left flap 200, and the top of the left flap ...

Embodiment

[0043] Now a kind of integrated stainless steel cable tray made by the present invention is tested and compared with a common product in the market. The test process is as follows;

[0044] 1. To process two different cable trays, process three groups respectively. It is necessary to ensure that the processing is complete without looseness, and compare the processing speed.

[0045] 2. Cooperate with a modulus of rupture device such as a modulus of rupture tester, squeeze the upper and lower ends of the embodiment to the member at the same time, measure how much MPA will be broken under high pressure strength, and then get how much MPA it can withstand.

[0046] 3. Use a combustion furnace to select different cable trays, put them into the furnace, use an open flame to continuously burn the cable trays, and observe the internal cables after 30 minutes.

[0047] The test data is as follows:

[0048] Processing speed / min Modulus of rupture / MPA Flame retardancy / %...

Abstract

The invention discloses an integrally formed stainless steel cable bridge and a preparation method thereof in the technical field of cable fittings. The integrally formed stainless steel cable bridgecomprises a bottom plate, a left folded plate, a right folded plate, a left mounting plate and a right mounting plate. A left side wall of the bottom plate is integrally formed and is connected to theleft folded plate, and a right side wall of the bottom plate is integrally formed and is connected to the right folded plate. According to the integrally formed stainless steel cable bridge and the preparation method thereof, the cable bridge can be quickly and effectively prepared by the combination of accessories and the improvement of preparation process, the steps are simplified, a compression plate containing a top pad and a bottom pad is added inside, the strength and toughness of stainless steel are increased, the local settlement deformation of the stainless steel with strong ductility after bearing weight is avoided, the compression plate is made of expanded graphite powder which can be released from ports of a left folded side and a right folded side after being exposed to hightemperature, the internal space of the cable bridge is filled, the cable is protected, the risk of open flame combustion is reduced, the loss is effectively reduced, and the safety of information transmission is protected.

Description

technical field [0001] The invention relates to the technical field of cable fittings, in particular to an integrally formed stainless steel cable bridge and a preparation method thereof. Background technique [0002] The cable is usually a rope-like cable twisted by several or several groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Insulating covering layer, used in power system, information transmission and instrumentation system and other fields. [0003] The cable tray is one of the accessories in the cable installation process. The cable tray is divided into trough type, tray type, ladder type, grid type and other structures. It is composed of brackets, brackets and installation accessories. The bridge in the building can be erected independently. , and can also be laid on various buildings (structures) and pipe gallery supports. It should reflect the characteristics of simpl...
