Technical Field
[0001] The utility model relates to the field of cable bridges, in particular to a corrosion-resistant lightweight bridge suitable for dangerous places. Background Art
[0002] There are various types of cable trays, including ladder-type trays, tray-type trays, trough-type trays, long-span trays, combined trays, and fiberglass trays. Each type of tray has its own unique characteristics and advantages, suitable for different application scenarios and needs. For example, ladder-type trays have the advantages of light weight, low cost, and easy installation, and are suitable for laying cables of general diameters; fiberglass trays are made of fiberglass and have the characteristics of corrosion resistance, aging resistance, light weight, and high strength. Fiberglass trays are made of high-quality resin and glass fiber materials and are specially processed to effectively resist corrosion from chemicals such as acids, alkalis, and salts, and are suitable for various highly corrosive environments.
[0003] However, when the FRP bridge is in use, the connection at the corners needs to be sealed to ensure the airtightness inside the FRP bridge and prevent the corrosive gas in the air from entering the interior of the FRP bridge. This greatly affects the efficiency of the FRP bridge installation.
[0004] Therefore, it is necessary to propose a corrosion-resistant lightweight bridge suitable for hazardous locations to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a corrosion-resistant lightweight bridge suitable for dangerous places, so as to solve the problem of slow processing at the corners of the glass fiber reinforced plastic bridge.
[0006] To achieve the above objectives, the present invention provides the following technical solutions: a corrosion-resistant lightweight bridge suitable for use in hazardous locations, comprising a first bridge and a second bridge, wherein a first cover plate and a second cover plate are movably provided on the inner sides of the first bridge and the second bridge, respectively, wherein two grooves are provided at the end of the first cover plate, and two plug plates are fixedly provided on the second cover plate corresponding to the ends of the first cover plate;
[0007] The inserting plate and the groove are both arranged in a rectangular shape, and the inserting plate is located inside the corresponding groove.
[0008] Preferably, the outer side of the inserting plate and the inner side of the groove are both provided with plush surfaces.
[0009] Preferably, there are at least two inserting plates and grooves.
[0010] Preferably, the first bridge and the second bridge are concave in cross section.
[0011] Preferably, the inserting plate and the groove are of equal length.
[0012] Preferably, the second bridge frame and the first bridge frame are connected by bolts.
[0013] Preferably, spherical rods are fixed on both sides of one end of the second bridge and the first bridge, and arc-shaped clamping rings are fixed on both ends of the first cover plate and the second cover plate. The arc-shaped clamping ring wraps the spherical rod, and the spherical rod and the arc-shaped clamping ring are slidably connected.
[0014] Technical effects and advantages of this utility model:
[0015] 1. The arrangement of the insert plate and the groove can enhance the sealing between the bridge frames when connecting the first bridge frame and the second bridge frame. The insert plate and the groove allow the connecting ends of the first cover plate and the second cover plate to engage with each other. The connection method is simple, and only requires aligning the insert plate and the groove. The insert plate and the groove have a simple structure and are highly practical.
[0016] 2. When inserting the plug-in board into the groove through the plush surface, the plush makes it easier to insert the plug-in board into the groove. The plush surface can block the fine particles in the air, and the amount of impurities on the plush can be observed. The gaps between the plush fibers can intercept some impurities. The amount of impurities can reflect the content of impurities in the air, which is convenient for preliminary observation of the flue gas.
[0017] 3.

The plug plate and the groove can adapt to the installation of the first bridge and the second bridge at horizontal angles, acute angles, and right angles, and maintain a tight seal.
[0018] 4. Through the setting between the plug plate and the groove, when the first cover plate and the second cover plate are pressed together, the protruding positions on the plug plate and the first cover plate abut against the cables between the first bridge and the second bridge, thereby pressing the cables and preventing them from being displaced.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] Example 1, the utility model provides Figure 1 - Figure 4 The corrosion-resistant lightweight bridge frame shown is suitable for hazardous places, including a first bridge frame 1 and a second bridge frame 2. The cross-section of the first bridge frame 1 and the second bridge frame 2 is concave, which is convenient for carrying cables. The material types of the first bridge frame 1 and the second bridge frame 2 are exactly the same. The first bridge frame 1 and the second bridge frame 2 are both fiberglass bridge frames, which are existing technologies and will not be described in detail here. The second bridge frame 2 and the first bridge frame 1 are connected by bolts, and the first bridge frame 1 and the second bridge frame 2 are connected by bolts. The bolts are existing technologies and will not be described in detail here. The bridge frames to be connected are docked and trimmed, and then the two bridge frames are connected by bolts.
[0026] A first cover plate 3 and a second cover plate 4 are movably provided on the inner sides of the first bridge 1 and the second bridge 2, respectively, and are mainly used to seal the upper ends of the first bridge 1 and the second bridge 2. Spherical rods 7 are fixed on both sides of one end of the second bridge 2 and the first bridge 1. Arc-shaped snap rings 8 are fixed on both ends of the first cover plate 3 and the second cover plate 4. The arc-shaped snap rings 8 wrap around the spherical rod 7, and the spherical rod 7 and the arc-shaped snap rings 8 are slidably connected;
[0027] The operator inserts the first cover plate 3 into the first bridge 1 so that the spherical rod 7 is inside the arc-shaped clamping ring 8 to complete the limiting of the first cover plate 3 and complete the connection of the first cover plate 3. The connection method of the second cover plate 4 is the same as that of the first cover plate 3.
[0028] When cables are installed in bridges, due to the different lines, the cables can be used in various situations, such as straight bridges, corner bridges, inclined bridges and other bridges with angles, which are commonly used cable connection methods.
[0029] Two grooves 6 are formed at the end of the first cover plate 3, and two plug-ins 5 are fixedly provided on the second cover plate 4 at the ends corresponding to the first cover plate 3. The plug-ins 5 and the grooves 6 are both rectangular in shape, and the plug-ins 5 are located inside the corresponding grooves 6 to ensure that the plug-ins 5 can enter the grooves 6 to complete the connection between the first cover plate 3 and the second cover plate 4. The number of plug-ins 5 and the grooves 6 are equal, and the length of the plug-ins 5 and the grooves 6 are equal;
[0030] By setting the plug plate 5 and the groove 6, the sealing between the bridge frames can be enhanced when connecting the first bridge frame 1 and the second bridge frame 2. The plug plate 5 and the groove 6 make the connecting ends of the first cover plate 3 and the second cover plate 4 engage with each other, and the connection method is simple, and it only needs to align the plug plate 5 and the groove 6. The plug plate 5 and the groove 6 have a simple structure and are highly practical.
[0031] The outer side of the inserting plate 5 and the inner side of the groove 6 are both provided with a plush surface. The plush surface is composed of fine and soft plush threads. When the inserting plate 5 is inserted into the groove 6, the plush is used to facilitate the insertion of the inserting plate 5 into the groove 6. In addition, the plush surface can block fine particles in the air, and the amount of impurities on the plush can be observed. The gaps between the plush fibers can be used to intercept some impurities, and the amount of impurities can be used to reflect the content of impurities in the air.
[0032] Operators regularly inspect and clean impurities on the fluff. Due to the material setting of the FRP bridge, it is especially suitable for hazardous places, including chemical plants, metallurgy, petroleum, chemical fiber, pharmaceuticals, offshore platforms and other places where corrosive substances exist. Chemical plants, in particular, need to burn harmful substances, and the flue gas that floats out is harmful flue gas, which is generally collected and centrally processed. However, once the flue gas leaks, the flue gas will float to the outside, and the impurities in the flue gas will adhere to the nearby fluff. Therefore, the operator can preliminarily observe the flue gas leakage through the fluff, which is suitable for hazardous places.
[0033] By changing the connection method between the plug-in plate 5 and the groove 6, when the angle between the first bridge 1 and the second bridge 2 is different due to the cable installation scenario, the connection angle between the plug-in plate 5 and the groove 6 is changed. It is only necessary to press the first cover plate 3 and the second cover plate 4 tightly to ensure the connection strength between the plug-in plate 5 and the groove 6. The plug-in plate 5 and the groove 6 can adapt to the horizontal angle installation, acute angle installation, and right angle installation of the first bridge 1 and the second bridge 2.
[0034] Through the arrangement between the plug plate 5 and the groove 6, when the first cover plate 3 and the second cover plate 4 are pressed together, the protruding positions on the plug plate 5 and the first cover plate 3 abut against the cables between the first bridge 1 and the second bridge 2, thereby pressing the cables and preventing them from being displaced.
[0035] Example 2, the utility model provides Figure 3The shown is a corrosion-resistant lightweight bridge suitable for hazardous locations. In order to ensure the adsorption of plush and the accuracy of detection, at least two plug plates 5 and grooves 6 are provided. By setting more plug plates 5 and grooves 6, the plush surface is increased and the observable plush surface is increased.
