Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a ladder-type bridge suitable for laying cables with different diameters. Background Art

[0002] A cable is a wire system used to transmit power or signals. It usually consists of multiple wires and an insulation layer that protects the wires from the outside environment and prevents current leakage or signal interference. The structure of a cable includes a conductor (usually copper or aluminum), an insulating material, and a protective layer (such as a shield and a sheath). Depending on the purpose, cables can be divided into power cables, communication cables, control cables, etc.

[0003] The ladder-type cable tray has the characteristics of high strength, light weight, low cost, beautiful appearance, easy installation and good air permeability. It is suitable for the laying of cables with generally larger diameters. At present, when laying cables, the cables are generally placed directly on the storage board of the ladder-type cable tray. The cables are not fixed and are easily moved due to vibration, external force or their own weight. This may cause friction between the cables or contact with the cable tray, thereby damaging the cable insulation layer. In addition, unfixed cables may appear messy, affecting the overall appearance and standardization of the cable system. Utility Model Content

[0004] The utility model aims to provide a ladder-type bridge frame which can quickly fix cables and is suitable for laying cables with different diameters.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A ladder-type bridge suitable for laying cables of different diameters includes two U-shaped side plates, a plurality of horizontal plates are arranged between the two U-shaped side plates, a plurality of Y-shaped blocks are installed on the upper surface of the horizontal plates, both sides of the Y-shaped blocks are provided with clearance grooves, the surface of the horizontal plates located on both sides of the Y-shaped blocks are provided with through grooves, the insides of the two through grooves are provided with plug blocks, and the tops of the two plug blocks are jointly installed with V-shaped blocks. The outer surface of the plug block is provided with a groove, the inside of the groove is provided with a tooth plate with arc-shaped teeth, and the outer surface of the horizontal plate is provided with a fixing mechanism that is engaged with the tooth plate.

[0007] It can be seen that by inserting the two plug-in blocks at the bottom of the V-shaped block into the two through grooves on both sides of the Y-shaped block respectively, the V-shaped block can be stuck in the give way groove. At this time, a rectangular structure is formed between the V-shaped block and the Y-shaped block. Therefore, after the cable is placed between the V-shaped block and the Y-shaped block, its outer surface can be clamped at four points, and the purpose of quickly fixing the cable can be achieved through the clamping cooperation between the fixing mechanism and the tooth plate. The cable is suitable for use with cables of different diameters and has a wide range of applications. The cables can be separated and fixed from each other, which is convenient for later replacement and maintenance of the cables and avoids the situation where the cables move and cause mutual friction and damage. The cables are separated from each other, which is conducive to air circulation, thereby improving the heat dissipation performance, avoiding cable damage due to overheating, and extending the service life of the cable and the entire system.

[0008] Furthermore, the fixing mechanism includes two fixing plates installed on the upper surface of the horizontal plate, the outer surfaces of the two fixing plates are connected with guide rods, the ends of the guide rods are installed with top plates, the outer surfaces of the two guide rods are slidably installed with sliding sleeves, an arc-shaped tooth block is connected between the two sliding sleeves, and the arc-shaped tooth block is adapted to the tooth plate, and a spring is sleeved on the outer surface of the guide rod, and the two ends of the spring are respectively abutted against the top plate and the sliding sleeve.

[0009] When the plug block is inserted into the through groove, the arc-shaped teeth of the tooth plate inside the groove and the arc-shaped surface of the end of the arc-shaped tooth block squeeze each other, thereby driving the arc-shaped tooth block to move outward and compressing the spring, so that the plug block can descend smoothly, and the V-shaped block and the Y-shaped block can clamp and fix the cable, and the other side surfaces of the arc-shaped teeth on the tooth plate and the end of the arc-shaped tooth block are both planes. When the plug block is lifted upward, the two planes abut against each other, thereby preventing the plug block from moving upward, ensuring the fixing effect of the cable and avoiding loosening. If it is necessary to release the fixation of the cable, just pull the arc-shaped tooth block outward to pull its end out of the tooth plate. At this time, the plug block loses its fixation, so it can be directly pulled upward.

[0010] Furthermore, the two arc-shaped tooth blocks located on both sides of the Y-shaped block are connected by a U-shaped connecting rod.

[0011] Since both sides of the bottom of the V-shaped block are connected with plug blocks, the arc-shaped tooth blocks on both sides can be driven to move outward at the same time by pulling the U-shaped connecting rod, so that one person can complete the cable removal work conveniently.

[0012] Furthermore, mounting holes are evenly formed on the surface of the U-shaped side plate along its length direction, and the ends of the cross plate are connected to the mounting holes by bolts.

[0013] Since the cross plate is mounted on the mounting hole by bolts, it is convenient to replace the cross plate and to reasonably adjust the distribution interval of the cross plate.

[0014] Furthermore, the surface of the Y-shaped block and the inner side surface of the V-shaped block are both provided with rubber pads, and the outer surface of the rubber pads is provided with anti-slip grooves.

[0015] By setting the rubber pads and anti-slip patterns, the friction between the Y-shaped block and the V-shaped block and the cable can be increased, which not only improves the fixing effect but also prevents the cable from being worn or the insulating layer from being damaged due to friction during the fixing process.

[0016] Furthermore, both the U-shaped side plates and the cross plate are made of stainless steel.

[0017] Stainless steel has good corrosion resistance, can resist the erosion of moisture, chemicals and other corrosive substances, has a long service life, and reduces the frequency of maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be described in detail below with reference to the accompanying drawings.

[0025] As Figures 1-5As shown, a ladder-type bridge suitable for laying cables of different diameters includes two U-shaped side plates 100, a plurality of cross plates 101 are arranged between the two U-shaped side plates 100, a plurality of Y-shaped blocks 102 are installed on the upper surface of the cross plates 101, and both sides of the Y-shaped blocks 102 are provided with clearance grooves 103, and the surface of the cross plates 101 is provided with through grooves 104 on both sides of the Y-shaped blocks 102, and the insides of the two through grooves 104 are provided with plug blocks 105, and the tops of the two plug blocks 105 are jointly installed with V-shaped blocks 106. The outer surface of the plug block 105 is provided with a groove 107, and the inside of the groove 107 is provided with a tooth plate 108 with arc-shaped teeth, and the outer surface of the cross plate 101 is provided with a fixing mechanism 200 that is engaged with the tooth plate 108.

[0026] When in use, the cable is first placed on the Y-shaped block 102, and then the two plug blocks 105 at the bottom of the V-shaped block 106 are respectively inserted into the two through grooves 104 on both sides of the Y-shaped block 102. At this time, both sides of the V-shaped block 106 are located in the two give-way grooves 103 on the Y-shaped block 102, and are pressed tightly on the cable inside thereof. The V-shaped block 106 can be fixed by the clamping cooperation between the fixing mechanism 200 and the tooth plate 108, so that it remains in a compressed state on the cable, thereby achieving the purpose of quickly fixing the cable, and is suitable for use with cables of different diameters, with a wide range of applications, and can separate and fix the cables from each other, facilitating the later replacement and maintenance of the cables, and avoiding the situation where the cables move and are damaged by mutual friction. In addition, the cables are separated from each other, which is conducive to air circulation, thereby improving the heat dissipation performance, avoiding damage to the cables due to overheating, and extending the service life of the cables and the entire system.

[0027] Specifically, the fixing mechanism 200 includes two fixing plates 201 mounted on the upper surface of the cross plate 101. Guide rods 202 are connected to the outer surfaces of the two fixing plates 201. The end of the guide rod 202 is provided with a top plate 203. A sliding sleeve 204 is slidably mounted on the outer surface of the two guide rods 202. An arc-shaped tooth block 205 is connected between the two sliding sleeves 204, and the arc-shaped tooth block 205 is adapted to the tooth plate 108. A spring 206 is sleeved on the outer surface of the guide rod 202. The two ends of the spring 206 are respectively abutted against the top plate 203 and the sliding sleeve 204. After the plug 105 is inserted into the through groove 104, the arc-shaped teeth of the tooth plate 108 inside the groove 107 and the arc-shaped surface at the end of the arc-shaped tooth block 205 are mutually pressed, thereby driving the arc-shaped tooth block 205 to move outward and compress the spring 206, so that the plug 105 can smoothly descend, and the V-shaped block 106 and the Y-shaped block 102 can clamp and fix the cable. The arc-shaped teeth on the tooth plate 108 and the other side surface at the end of the arc-shaped tooth block 205 are both flat surfaces. When the plug 105 is lifted upward, the two flat surfaces are mutually abutted, so that the plug 105 can be prevented from moving upward, ensuring the fixing effect on the cable and avoiding loosening. If it is necessary to release the fixing of the cable, only need to pull the arc-shaped tooth block 205 outward to extract its end from the tooth plate 108. At this time, the plug 105 loses its fixation, so it can be directly pulled out upward.

[0028] Specifically, the two arc-shaped tooth blocks 205 on both sides of the Y-shaped block 102 are connected by a U-shaped connecting rod 300. Since the two sides of the bottom of the V-shaped block 106 are both connected with plugs 105, by pulling the U-shaped connecting rod 300, the arc-shaped tooth blocks 205 on both sides can be simultaneously driven to move outward, which is convenient for a single person to complete the removal work of the cable.

[0029] Specifically, mounting holes 400 are uniformly opened on the surface of the U-shaped side plate 100 along its length direction. The end of the cross plate 101 is connected to the mounting holes 400 through bolts 401. Since the cross plate 101 is installed on the mounting holes 400 through bolts 401, it is convenient to replace the cross plate 101 and to reasonably adjust the distribution interval of the cross plate 101.

[0030] Specifically, rubber pads are provided on the surface of the Y-shaped block 102 and the inner side surface of the V-shaped block 106. Anti-slip lines are opened on the outer surface of the rubber pads. Through the setting of the rubber pads and the anti-slip lines, the friction between the Y-shaped block 102 and the V-shaped block 106 and the cable can be increased, not only improving the fixing effect, but also preventing the cable from being worn or the insulating layer being damaged due to friction during the fixing process.

[0031] Specifically, both the U-shaped side plate 100 and the cross plate 101 are made of stainless steel. The stainless steel material has good corrosion resistance, can resist the erosion of moisture, chemicals and other corrosive substances, has a long service life, and reduces the frequency of maintenance and replacement.

[0032] The above is a detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific embodiments of the present utility model are only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, several equivalent substitutions or obvious variations are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
