[0031] The present embodiment is designed for the laying of cable optical fibers on a gable roof. In the present embodiment, the roof positioning assembly 11 is a supporting structure arranged on the roof. The roof positioning assembly 11 is composed of a number of support frames, which are arranged along the slope angles of the front and rear surfaces of the roof ridge to maintain the stability of the installation on the roof ridge; the bridge support 13 is used for the turnover of the cable and for positioning the direction of the entire cable; the extension bracket 12 is used for trajectory positioning and support of the lowered cables.
[0032] The import wiring frame 14 and the export wiring frame 15 are arranged at both ends of the bridge support 13. The import wiring frame 14 is used for the introduction of the docking cables, and the export wiring frame 15 is used for the output of the carrying cables. The import wiring frame 14 and the export wiring frame 15 can be flipped relative to the bridge support 13, so that the import wiring frame 14, the bridge support 13 and the export wiring frame 15 are combined into an arched structure to adapt to the slope angle of the roof ridge. A plurality of cable clamps 16 are provided on the bridge support 13, and the clamp adjustment member 17 drives and adjusts the cable clamps 16 to clamp and position the cables; during operation, the cables are introduced from the introduction wiring rack 14, and the introduction wiring rack 14 supports the cables and guides them to the positioning interval of the bridge support 13, and then pass through the output wiring rack 15 at the other end of the bridge support 13, and the output wiring rack 15 supports the other end of the cables, and the extension bracket 12 is located in the lower area of the output wiring rack 15, and the extension bracket fixing frame 21 is used as the supporting structure for lowering the cables, and the positioning support member 23 is used to support the cables in sequence The positioning support member 23 uses a sub-bracket 29 as a lateral support structure. The sub-bracket 29 is provided with a first support bracket 25 and a second support bracket 27. The first support bracket 25 and the second support bracket 27 form an oblique support structure. After the cable is lowered, it is turned around by the first support tray 26 and then introduced into the second support tray 28, and then supported and turned around by the second support tray 28. During the whole process, the cable tends to be tightened to reduce the influence of the cable's own gravity on the cables in the upper roof area and avoid the problem of loose cables. After the cable is laid, the cable clamp 16 is driven to completely clamp the cable to fix the cable.
[0033] This embodiment provides a stable positioning for laying cables on the gable roof, effectively reducing the influence of gravity after the cables are lowered, and can ensure that the cables are fixed at a preset position without problems of movement or falling off.
[0034] In one embodiment, see Figure 2 , Figure 4 and Figure 5 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the import wiring rack 14 and the export wiring rack 15 is designed as follows:
[0035] The import wiring frame 14 includes an import frame 31 installed on the bridge support 13 and a plurality of import rollers 34 installed on the import frame 31. The import frame 31 is provided with a plurality of shaft positioning sleeves 32 arranged equidistantly, and the shaft positioning sleeves 32 are provided with import rollers 33. The import rollers 34 are installed on the corresponding import rollers 33. The export wiring frame 15 includes an export frame 41 installed on the bridge support 13, a plurality of export rollers 42 arranged on the export frame 41, and export rollers 43 installed on the export rollers 42. The export rollers 43 are matched one by one with the import rollers 34.
[0036] The introduction wiring rack 14 is used for the introduction of cables. Since the directions of cable introduction may be different, a number of introduction rollers 34 are installed on the introduction rack 31 of this embodiment. The introduction rollers 34 are arranged equidistantly on the introduction rack 31. Each introduction roller 34 independently supports the cable. Each cable is introduced obliquely and in parallel along the corresponding introduction roller 34. In this way, when the cables are introduced into the positioning interval below the bridge support 13, a vertical parallel arrangement is formed, which is conducive to the synchronous clamping and positioning of the cables by the cable clamp 16. At the same time, a number of export rollers 43 are arranged above the export roller shaft 42. When the parallel-arranged cables are subsequently output from the bottom of the export wiring rack 15, each cable is supported by the export roller 43 accordingly, and is vertically dispersed, and then each cable is independently lowered for wiring.
[0037] Preferably, the introduction rollers 33 are connected by a transmission belt 35, and a motor 36 is also provided on the introduction frame 31, and the introduction roller 33 at the driving end is connected to the motor 36. In this embodiment, the cable clamp 16 can first maintain the clamping state of the cable, not completely clamped, and the cable has space for shuttle movement. The motor 36 is a driving device, which drives the introduction roller 34 to rotate through the transmission belt 35 to assist in driving the cable to be laid backward, so that the staff can spread the cable conveniently.
[0038] In one case of the present embodiment, the bridge support 13 includes a bridge support frame 51 and a cable guide frame 52 arranged on the bridge support frame 51, the export frame 41 and the import frame 31 are both installed at the two ends of the cable guide frame 52, and the end of the cable guide frame 52 is provided with a rotating head 53, and the export frame 41 and the import frame 31 are both rotatably installed on the rotating head 53 through an arc-shaped adjustment groove 54. The cable guide frame 52 is used to assist in locating the direction of the cable on the roof, and the bridge support frame 51 can be installed with a related shielding shed or frame to provide sunshade, rainproof, reduce signal interference, and achieve good anti-fouling and anti-interference capabilities. The export frame 41 and the import frame 31 at both ends can adjust the relevant installation angles through the rotating head 53, and then lock the cable guide frame 52 and the rotating head 53 to adapt to the slope angle of the roof.
[0039] In one embodiment, see Figure 2 and Figure 6 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the cable clamp 16 and the clamp adjustment member 17 is designed as follows:
[0040] The cable guide frame 52 is provided with a frame transverse support rail 71, the cable clamp 16 includes a clamp fixed frame 72 and a clamp movable frame 73, the clamp fixed frame 72 is fixedly installed on the frame transverse support rail 71, the clamp movable frame 73 is slidably installed on the frame transverse support rail 71, the clamp adjustment member 17 includes a pusher 61 and a movable block 62, the pusher 61 is fixedly installed on the cable guide frame 52, the movable block 62 is provided with a snap-fit groove 65, the movable block 62 is slidably installed on the cable guide frame 52 through the snap-fit groove 65, a push rod 64 is provided between the pusher 61 and the movable block 62, the pusher 62 is also provided with a push rod 64, the push rod 64 is connected to the movable block 62, and the movable block 62 is fixedly connected to the side wall of the clamp movable frame 73.
[0041] The clamp fixed frame 72 is fixedly installed, and the clamp movable frame 73 is movably installed. The clamp movable frame 73 is pinched relative to the clamp fixed frame 72, thereby completing the clamping and fixing of the cable; during operation, the pusher 61 is used as a driving tool, and the pusher 61 drives the pushing rod 64 to move, thereby driving the movable block 62 to move. The limiting column 63 is used to limit the movement trajectory of the movable block 62, and the clamp movable frame 73 is driven by the movable block 62 to move relative to the clamp fixed frame 72, thereby pinching the clamp fixed frame 72 and the clamp movable frame 73.
[0042] For the cable clamping structure, this embodiment also has the following design:
[0043] The frame bodies of the clamp fixing frame 72 and the clamp movable frame 73 are both provided with a clamp block mounting seat 74 and a cable clamp block 75 mounted on the clamp block mounting seat 74. The frame bodies of the clamp fixing frame 72 and the clamp movable frame 73 are also provided with an adjusting screw rod 76, and the clamp block mounting seat 74 is slidably mounted on the adjusting screw rod 76. The cable clamp block 75 is a tool for clamping cables. The cable clamp block 75 is slidably mounted in the frame body of the clamp fixing frame 72 or the clamp movable frame 73 through the clamp block mounting seat 74, so that the clamping position of the cable clamp block 75 can be slightly adjusted; in this way, the position difference caused by the difference in the outer diameter of cables of different sizes can be adjusted in a targeted manner.
[0044] The cable clamp block 75 includes a clamp block seat 82, a clamp block mounting plate 81 mounted on the clamp block seat 82, and a clamping piece 83 arranged on the inner edge of the clamp block mounting plate 81. The cable clamp block 75 as a clamping tool is also composed of multiple parts. The clamp block mounting plate 81 is a fixed structure, and the clamping piece 83 is used to contact the surface of the cable. The clamping piece 83 is a soft structure and has different patterns on its clamping surface. Different types of clamping pieces 83 can be replaced according to the material of the cable.
[0045] A base block 84 is also provided at the bottom of the clamp fixed frame 72 and the clamp movable frame 73, and a cable pad 85 is installed on the base block 84. The cable pad 85 is a support sheet with a certain elasticity, which is used to support the bottom of the cable to maintain the clamping effect and have a certain buffering capacity.
[0046] In one embodiment, see Figure 1 , Figure 3 and Figure 7 This embodiment is a further design of the above embodiment. On this basis, the specific implementation structure of the positioning support member 23 is designed as follows:
[0047] The sub-bracket 29 is an oblique frame structure, and the first support bracket 25 includes a positioning base 91 installed on the sub-bracket 29 and a support roller 94 arranged on a support plate 92 on the positioning base 91, and a clamping plate 93 is installed on both sides of the support roller 94. The cable uses the support roller 94 as a lowered support structure, and changes direction from bottom to top with the support roller 94 as a support point. At the same time, the cable is limited in the disk body interval formed by the clamping plates 93 on both sides. After the cable passes through the support roller 94 and changes direction, it is erected on the second support tray 28 from bottom to top, and then the second support tray 28 is used as a turning wheel body from top to bottom, so that the cable is kept taut and the problem of cable loosening caused by the cable's own counterweight is avoided.
[0048] In one case of the present embodiment, a driving frame plate 101 is also installed on the sub-bracket 29, and a driving machine 102 and a hoisting drum 103 installed on the driving end of the driving machine 102 are provided on the driving frame plate 101, and a retracting rope 104 is wound on the hoisting drum 103, and the support plate 92 is installed on the positioning base 91 through a plate body mounting shaft 105, and a torsion spring sleeve 106 is provided between the plate body mounting shaft 105 and the plate body of the positioning base 91, and the retracting rope 104 is connected to the plate end of the support plate 92.
[0049] The present embodiment can also adjust the oblique support angle of the first support tray 26. The first support tray 26 is installed on the support support plate 92. The support support plate 92 is rotatably installed through the plate body mounting shaft 105, but the supporting torque of the plate body mounting shaft 105 is maintained by the torsion spring sleeve 106. The driving machine 102 is used as an adjustment tool to drive the winch drum 103 to move, thereby adjusting the retracting rope 104, and then pulling the support support plate 92 to rotate with the plate body mounting shaft 105 to overcome the torque of the torsion spring sleeve 106. After loosening the retracting rope 104, the torsion spring sleeve 106 releases its elastic potential energy and drives the plate body mounting shaft 105 to rotate and reset, so that the directional support position of the first support tray 26 can be adjusted to meet the laying needs of the cables, maintain the first support tray 26 to form a sufficient support trend, and overcome the problem of cable movement and loosening.
