Description

Technical Field

[0001] The present invention relates to a cable bridge, in particular to a reinforced cable bridge used in the field of cable bridges. Background Art

[0002] The reinforced adjustable cable tray is divided into trough type, tray type, ladder type, grid type and other structures. It is composed of brackets, supports and installation accessories. The bridge can be erected independently in the building or attached to various buildings (structures) and pipe gallery brackets. It should have the characteristics of simple structure, beautiful appearance, flexible configuration and easy maintenance. All parts need to be galvanized and installed in the open-air bridge outside the building.

[0003] For example, the specification of patent application number CN201821768499.0 discloses a reinforced cable tray, including a top plate, side plates and a first reinforced keel, the side plates are respectively located on both sides of the top plate, and the first reinforced keel is embedded in the inside of the side plates, a bottom plate is provided between the two side plates away from the top plate, a reinforcement layer is installed above the bottom plate, and a second reinforced keel is embedded in the inner center of the bottom plate, rollers are movably installed above the reinforcement layer, and the outer surfaces on both sides of the rollers are rotatably connected with fixed rings, a rotating rod is rotatably connected at the inner center of the bottom plate, and baffles are welded to the outer surfaces of the front and rear ends of the rotating rods. The reinforced cable tray can rotate and transport the cable when the cable is adjusted and pulled, which is convenient for pulling the cable while preventing damage to the cable casing during sliding, doubly increasing the load capacity, and the size of the vents can be freely adjusted according to the needs of the use occasion, which is convenient for heat dissipation and ventilation, and a triangular structure is formed while reserving a ventilation duct, which is convenient for stable fixation.

[0004] However, based on the above search and in combination with the prior art, it is found that the existing cable tray is not convenient for pulling cables. Although rollers are provided in the cable tray similar to the above-mentioned one, since multiple cables are in contact with the same roller and the friction between two adjacent cables is large, it is easy to pull other cables synchronously when pulling one of the cables alone, which is inconvenient for individual operation of the cables. Therefore, a reinforced cable tray is proposed to improve the above-mentioned problem. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is.

[0006] In order to solve the above problems, the present invention provides a reinforced cable tray, comprising a pressure-bearing frame and further comprising: Isolation plates, a plurality of isolation plates are provided, and the plurality of isolation plates are vertically arranged on the inner side of the pressure-bearing frame and arranged in sequence along the width direction of the pressure-bearing frame; Ball bearings, a plurality of balls are provided, and the plurality of balls are evenly and movably installed on the inner bottom end of the pressure-bearing frame; A plurality of reinforcing rib plates are provided, and the plurality of reinforcing rib plates are fixed to the side ends of the pressure-bearing frame at equal intervals along the length direction of the pressure-bearing frame.

[0007] In the above-mentioned reinforced cable bridge, through the setting of isolation plates and ball bearings, multiple cables can be separated one by one using the isolation plates. In conjunction with the ball bearings, one of the cables can be smoothly pulled alone without interfering with other cables, making construction and maintenance operations more convenient.

[0008] As a further supplement to the present application, the isolation plate is provided with rolling rollers on both side ends along the width direction of the pressure-bearing frame, and the inner walls on both sides opposite to the width of the pressure-bearing frame are also provided with rolling rollers on both sides, which are also provided with rolling rollers. By setting the rolling rollers, rolling friction can occur between the rolling rollers and the cable when the cable is pulled, and the ball bearings can be used to further reduce the resistance when the cable is pulled.

[0009] As a further supplement to the present application, the isolation plate is horizontally slidably installed on the inner side of the pressure frame along the width direction of the pressure frame; Limiting slide rails are integrated on the upper and lower inner walls of the pressure frame, and limiting sliding openings that slide with the limiting slide rails are provided on the upper and lower ends of the isolation plate; the isolation plate can slide flexibly on the inside of the pressure frame, thereby being able to adapt to the installation requirements of cables of different diameters.

[0010] As a further supplement to the present application, the rolling rollers on the pressure frame and the rolling rollers on the limiting slide rails are staggered, and the rolling rollers on two adjacent limiting slide rails are also staggered; the staggered arrangement of the rolling rollers on two adjacent vertical planes can reduce the required space when the isolation panels are stacked horizontally, thereby freeing up more space for cable installation to a certain extent.

[0011] As a further supplement to the present application, the ball is evenly and movably installed on the upper end of the limiting slide rail, and an arc-shaped hole for the ball to pass through is provided on the isolation plate; setting the ball on the upper end of the limiting slide rail allows the isolation plate to have rolling friction with the ball during movement. Compared with the direct sliding friction with the limiting slide rail, the resistance of the rolling friction is smaller, making the adjustment of the isolation plate more flexible.

[0012] As a further supplement to the present application, the cross-section of the limiting slide rail located at the bottom end of the pressure-bearing frame is T-shaped, and the cross-section of the limiting slide rail located at the top end of the pressure-bearing frame is inverted T-shaped, and the limiting slide mouth is arranged to slide in conjunction with the limiting slide rail; the limiting slide rail with a T-shaped cross-section cooperates with the isolation plate to exert a tightening effect on the bottom surface of the pressure-bearing frame, effectively preventing the bottom surface of the pressure-bearing frame from deforming, and enhancing the overall strength of the pressure-bearing frame.

[0013] As a further supplement to the present application, a plurality of inspection openings are equidistantly arranged at the bottom end of the pressure-bearing frame along its length direction, and a sealing cover plate is detachably installed at the bottom end of the pressure-bearing frame; by opening the sealing cover plate, the inspection opening facilitates the staff to perform local inspection of the cable.

[0014] As a further supplement to the present application, one end of the sealing cover plate is hinged to the bottom end of the pressure frame, and the other end of the sealing cover plate is clamped to the pressure frame; The top surface of the sealing cover plate is fitted with the bottom end of the pressure frame, and the bottom surface of the sealing cover plate is integrated with multiple equidistantly arranged cooling fins; the heat generated during cable operation is diffused into the sealing cover plate through the pressure frame, and the sealing cover plate is used for heat dissipation. The cooling fins increase the heat dissipation area of ​​the sealing cover plate and improve the heat dissipation effect. In addition, the cooling fins can play a good anti-collision role when it is hit from the bottom, and better protect the pressure frame. Multiple cooling ventilation holes are provided on the pressure frame and the isolation plate to provide stable heat dissipation for the cables inside the pressure frame.

[0015] As another supplement to the present application, a connecting shaft is coaxially fixed to one end of the rolling roller, and a striking ball is vertically fixedly installed to the end of the connecting shaft away from the rolling roller through an elastic connecting piece; The side ends of the pressure frame and the isolation plate are provided with grooves for the connecting shaft, the elastic connecting piece and the striking ball to rotate along with the rolling roller; Striking plates that collide with the striking ball are fixedly installed at equal intervals on the inner wall of the groove; through the coordinated arrangement of the elastic connector, the striking ball and the striking plate, when the cable is pulled, the friction between the cable and the rolling roller can be used to rotate the rolling roller. At this time, the rotating rolling roller rotates with the elastic connector and the striking ball through the connecting shaft, so that the striking ball hits the striking plate, making a crisp hitting sound, which can effectively reduce the occurrence of cable theft; in addition, during the process of the elastic connector rotating with the striking ball, after the striking ball contacts the striking plate for the first time, it is blocked by the striking plate and stops moving. At this time, the elastic connector is deformed (accumulated force). When it continues to rotate, the elastic connector is deformed until the striking ball is separated from the striking plate. At this time, the striking ball is quickly swung to and hits the next striking plate under the elastic force of the elastic connector, ensuring that a crisp hitting sound can be emitted, reminding surrounding personnel and scaring off cable stealers.

[0016] As a further supplement to the present application, the reinforcing rib plate is triangular in shape, and the surfaces of the pressure frame, isolation plate and reinforcing rib plate are all galvanized; the triangular-shaped reinforcing rib plate provides a more stable support, making the strength of the pressure frame higher.

[0017] In summary, through the setting of isolation plates and ball bearings, multiple cables can be separated one by one by using the isolation plates, and in conjunction with the ball bearings, one of the cables can be pulled smoothly and separately without interfering with other cables, making construction and maintenance operations more convenient; by setting rolling rollers on the sides of the isolation plates and the pressure-bearing frame, rolling friction can occur between the rolling rollers and the cables when the cables are pulled, and in conjunction with the ball bearings, the resistance when pulling the cables is further reduced; in addition, by sliding the isolation plates on the inner side of the pressure-bearing frame, it can adapt to the installation requirements of cables of different diameters, and setting the ball bearings on the upper end of the limiting slide rail can cause the isolation plates to have rolling friction with the ball bearings during movement, and the resistance of the rolling friction is smaller than the direct sliding friction with the limiting slide rail, making the adjustment of the isolation plates more flexible; in addition, the T-section limiting slide rail in conjunction with the isolation plate can have a tightening effect on the bottom surface of the pressure frame, effectively preventing the deformation of the bottom surface of the pressure frame, and enhancing the overall strength of the pressure frame.

[0020] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0021] The first implementation method: The present invention provides a reinforced cable tray, see Figure 1-3 , including a pressure-bearing frame 1, an isolation plate 2, balls 3 and a reinforcing rib plate 8.

[0022] Among them, there are multiple isolation plates 2, and the multiple isolation plates 2 are vertically arranged on the inner side of the pressure frame 1, and are arranged in sequence along the width direction of the pressure frame 1, so as to separate two adjacent cables to avoid contact between the two cables, thereby facilitating pulling one of the cables separately.

[0023] Among them, Figure 6 and Figure 7 As shown, a plurality of balls 3 are provided, and the plurality of balls 3 are evenly and movably installed on the inner bottom end of the pressure frame 1. By providing the isolation plate 2 and the balls 3, the isolation plate 2 can be used to separate the plurality of cables one by one. With the help of the balls 3, one of the cables can be smoothly pulled alone without interfering with other cables, making the construction and maintenance operations more convenient.

[0024] A plurality of reinforcing rib plates 8 are provided, and the plurality of reinforcing rib plates 8 are fixed at the side ends of the pressure frame 1 at equal intervals along the length direction of the pressure frame 1. The reinforcing rib plates 8 are triangular in shape, and the triangular-shaped reinforcing rib plates 8 provide more stable support, thereby making the strength of the pressure frame 1 higher. The surfaces of the pressure frame 1, the isolation plate 2 and the reinforcing rib plates 8 are all galvanized.

[0025] like Figure 4 and Figure 5 It is shown that rolling rollers 5 are installed vertically and rotatably on both side ends of the isolation plate 2 along the width direction of the pressure frame 1, and rolling rollers 5 are also installed vertically and rotatably on the inner walls on both sides opposite to the width of the pressure frame 1; through the setting of the rolling rollers 5, rolling friction can occur between the rolling rollers 5 and the cable when the cable is pulled, and the ball bearings 3 can be used to further reduce the resistance when pulling the cable.

[0026] like Figure 5 , Figure 6 and Figure 7 It is shown that the isolation plate 2 is horizontally slidably installed on the inner side of the pressure frame 1 along the width direction of the pressure frame 1, and the upper and lower inner walls of the pressure frame 1 are integrally provided with limiting slide rails 4, and the upper and lower ends of the isolation plate 2 are provided with limiting slides 7 that slide with the limiting slide rails 4; the isolation plate 2 can slide flexibly on the inner side of the pressure frame 1, so as to adapt to the installation requirements of cables of different diameters.

[0027] like Figure 4 It is shown that the rolling roller 5 on the pressure frame 1 is staggered with the rolling roller 5 on the limiting slide rail 4, and the rolling rollers 5 on two adjacent limiting slide rails 4 are also staggered; the staggered arrangement of the rolling rollers 5 on two adjacent vertical planes can reduce the required space when the isolation panels 2 are stacked horizontally, thereby freeing up more space for cable installation to a certain extent.

[0028] like Figure 6 and Figure 7 It is shown that the ball 3 is evenly and movably installed on the upper end of the limiting slide rail 4, and an arc-shaped hole for the ball 3 to pass through is provided on the isolation plate 2; arranging the ball 3 on the upper end of the limiting slide rail 4 allows the isolation plate 2 to have rolling friction with the ball 3 during movement. Compared with the direct sliding friction with the limiting slide rail 4, the resistance of the rolling friction is smaller, making the adjustment of the isolation plate 2 more flexible.

[0029] like Figure 7 It is shown that the cross-section of the limiting slide rail 4 located at the bottom end of the pressure frame 1 is T-shaped, and the cross-section of the limiting slide rail 4 located at the top end of the pressure frame 1 is inverted T-shaped, and the limiting slide mouth 7 is slidably matched with the limiting slide rail 4; the limiting slide rail 4 with a T-shaped cross-section cooperates with the isolation plate 2 to exert a tightening effect on the bottom surface of the pressure frame 1, effectively preventing the bottom surface of the pressure frame 1 from deforming, and enhancing the overall strength of the pressure frame 1.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a plurality of inspection openings 9 are equidistantly arranged at the bottom end of the pressure frame 1 along its length direction, and a sealing cover plate 10 is detachably installed at the bottom end of the pressure frame 1; when the sealing cover plate 10 is opened, the inspection opening 9 facilitates the staff to perform local inspection of the cable.

[0031] like Figure 1 , Figure 2 and Figure 3 It is shown that one end of the sealing cover plate 10 is hinged to the bottom end of the pressure frame 1, the other end of the sealing cover plate 10 is snap-connected with the pressure frame 1, the top surface of the sealing cover plate 10 is in contact with the bottom end of the pressure frame 1, and the bottom surface of the sealing cover plate 10 is integrated with a plurality of heat dissipation fins 11 equidistantly arranged; the heat generated during the cable operation is diffused into the sealing cover plate 10 through the pressure frame 1, and the sealing cover plate 10 is used to dissipate the heat, and the heat dissipation fins 11 increase the heat dissipation area of ​​the sealing cover plate 10 and improve the heat dissipation effect. In addition, the heat dissipation fins 11 can play a good anti-collision role when it is hit from the bottom, so as to better protect the pressure frame 1.

[0032] like Figure 6 As shown, a plurality of heat dissipation ventilation holes 6 are provided on the pressure frame 1 and the isolation plate 2 to provide stable heat dissipation for the cables inside the pressure frame 1 .

[0033] Compared with the prior art, in this solution, by setting the isolation plate 2 and the ball bearing 3, the isolation plate 2 can be used to separate multiple cables one by one, and with the ball bearing 3, one of the cables can be pulled smoothly without interfering with other cables, making construction and maintenance operations more convenient; by setting the rolling roller 5 on the side of the isolation plate 2 and the pressure frame 1, rolling friction can occur between the rolling roller 5 and the cable when the cable is pulled, and the ball bearing 3 can be used to further reduce the resistance when the cable is pulled; In addition, by slidingly installing the isolation plate 2 on the inner side of the pressure frame 1, it can adapt to the installation requirements of cables of different diameters, and setting the ball 3 on the upper end of the limiting slide rail 4 can make the isolation plate 2 have rolling friction with the ball 3 during movement. Compared with the direct sliding friction with the limiting slide rail 4, the resistance of the rolling friction is smaller, making the adjustment of the isolation plate 2 more flexible; in addition, the T-section limiting slide rail 4 cooperates with the isolation plate 2 to have a tightening effect on the bottom surface of the pressure frame 1, effectively preventing the bottom surface of the pressure frame 1 from deforming, and enhancing the overall strength of the pressure frame 1.

[0034] Second implementation method: Compared with the first embodiment, this embodiment provides a reinforced cable tray, so that this embodiment has a certain function of preventing the cable from being stolen. Figure 8-9 A connecting shaft 12 is coaxially fixed to one end of the rolling roller 5, and a striking ball 16 is vertically fixedly installed on the end of the connecting shaft 12 away from the rolling roller 5 through an elastic connecting piece 15. The side ends of the pressure frame 1 and the isolation plate 2 are provided with grooves 13 for the connecting shaft 12, the elastic connecting piece 15 and the striking ball 16 to rotate with the rolling roller 5, and striking plates 14 that collide with the striking ball 16 are fixedly installed at equal intervals on the inner wall of the groove 13.

[0035] By means of the coordinated arrangement of the elastic connector 15, the striking ball 16 and the striking plate 14, when the cable is pulled, the friction between the cable and the rolling roller 5 can be used to rotate the rolling roller 5. At this time, the rotating rolling roller 5 rotates with the elastic connector 15 and the striking ball 16 through the connecting shaft 12, so that the striking ball 16 hits the striking plate 14, making a crisp hitting sound, which can effectively reduce the occurrence of cable theft incidents. In addition, during the process of the elastic connector 15 rotating with the striking ball 16, after the striking ball 16 first contacts the striking plate 14, it is blocked by the striking plate 14 and stops moving. At this time, the elastic connector 15 is deformed (accumulated force). When it continues to rotate, the elastic connector 15 is deformed until the striking ball 16 is separated from the striking plate 14. At this time, the striking ball 16 is quickly thrown to and hits the next striking plate 14 under the elastic force of the elastic connector 15, ensuring that a crisp hitting sound can be emitted to remind the surrounding personnel and scare away the cable thief.

[0036] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
