DETAILED DESCRIPTION

[0007] The cable installation and fixing bracket with bird-repelling function described in the present invention is as follows: Figure 1-11 As shown, it includes a vertically arranged column 1, a detachable base 2 is provided at the bottom of the column 1, a limit top plate 3 is provided at the top of the column 1, and a cable mounting seat 4 is installed on the column 1 below the limit top plate 3. The column 1 can be used as a pole, and the base 2 is the part that is fixedly connected to the ground by the column 1. On the premise of being detachable and easy to erect, it can also lower the center of gravity of the column 1 and improve the stability of the entire column 1. The cable mounting seat 4 is a base for installing cables. The cable mounting seat 4 can be lifted and lowered vertically along the column 1. Before the column 1 is erected, the cable can be installed on the cable mounting seat 4. After the column 1 is erected, the cable mounting seat 4 can drive the cable to move up to the top position of the column 1, thereby completing the installation.

[0008] In order to achieve stable upward movement of the cable mounting seat 4 in the length direction of the column 1 and avoid shaking of the cable mounting seat 4 during the vertical ascent, a guide groove 5 is provided in the length direction of the column 1, and a guide block 6 matching the guide groove 5 is provided in the cable mounting seat 4.

[0009] A fixed pulley 11 is installed at the top of the column 1, and a pull rope 12 is installed on the fixed pulley 11. A hook 13 cooperating with the pull rope 12 is provided on one side of the cable mounting seat 4, and a through hole 14 for allowing the pull rope 12 to pass downward is opened on the other side of the cable mounting seat 4. Pulling the pull rope 12 can drive the cable mounting seat 4 to move from the bottom end position of the column 1 to the position of the limiting top plate 3, and be fixed on the column 1 at the lower side of the limiting top plate 3 through the mounting seat locking mechanism.

[0010] After the operator completes the installation of the components on the cable mounting seat 4 on the ground, he pulls the pull rope 12 downwards. Under the reversing action of the fixed pulley 11, the pull rope 12 on the other side can drive the cable mounting seat 4 to move upward. After the cable mounting seat 4 moves to the position of the limit top plate 3, it can be positioned through the mounting seat locking mechanism, wherein the mounting seat locking mechanism can be an existing locking rod with a telescopic function or other locking mechanisms such as a clamp ring that can tighten and expand, which can achieve relative locking of the cable mounting seat 4 on the column 1 and ensure relative stability on the column 1 after locking.

[0011] In order to enable the cable mounting seat 4 to synchronously raise the cable to the specified installation height position during the vertical upward movement along the column 1, and to prevent the cable from being detached from the cable mounting seat 4, a plurality of cable anti-detachment mechanisms arranged side by side are installed on the cable mounting seat 4. Each cable anti-detachment mechanism includes a clamping frame 7, which is fixedly arranged on the cable mounting seat 4, and two vertically arranged clamping rollers 8 are installed in the clamping frame 7, and the cable is inserted and installed between the two clamping rollers 8. The outer periphery of the clamping roller 8 can be provided with a plurality of protrusions to increase the friction between the cable and the clamping roller 8, and prevent the cable from being reversely pulled out between the clamping rollers 8.

[0012] A one-way bearing 9 is installed on the rotating shaft of each clamping roller 8. The one-way bearing 9 only allows the cable to pass out in one direction between the clamping rollers 8. A cover plate 10 that can be rotated and opened and closed is installed on the clamping frame 7. After opening the cover plate 10, the cable can be placed in the clamping frame 7. After being placed between the clamping rollers 8, the cover plate 10 is rotated and closed, and the length of the cable extending out of the clamping rollers 8 is adjusted on the ground. After the adjustment is completed, the pull rope 12 can be pulled to drive the cable mounting seat 4 to move up. During the upward movement, due to the setting of the one-way bearing 9, the cable will not move in the opposite direction and be pulled out, and the length pulled out on the ground will be maintained until it reaches the top position of the column 1, leaving a set length of cable between the two columns 1, and no high-altitude operation adjustment is required after erection. The mutual connection between the cover plate 10 and the clamping frame 7 can be achieved by installing structures such as attracting magnets or snaps. After the cable is installed, it will be pressed down on the cable mounting seat 4 due to its own gravity. The cover plate 10 and the clamping frame 7 do not need a large connection strength. The operator can manually open or close it to achieve the positioning of the cable.

[0013] In order to prevent birds from staying on the cable mounting seat 4 or building nests on the cable mounting seat 4 and affecting the normal use of the cable, a bird-repelling mechanism is also installed on the cable mounting seat 4, which can prevent birds from falling on the cable mounting seat 4 or the cable anti-falling mechanism. The bird-repelling mechanism can be an existing sound and light alarm device or a physical protective device with thorns, which can achieve the corresponding bird-repelling function.

[0014] When using the above-mentioned cable installation and fixing bracket with bird-repelling function, first fix the base 2 on the ground at a preset position, then the staff arranges the cables to be installed one by one, opens the cover 10, and puts the cables into the clamping rollers 8 in sequence. After closing the cover 10, pull the cable to move in one direction, leaving a specified length of cable to be installed between the two columns 1, and then install the bird-repelling mechanism, and install the pull rope 12 on the fixed pulley 11 of the horizontally placed column 1, so that one end of the pull rope 12 is connected to the hook 13, and the other end of the pull rope 12 bypasses the fixed pulley 11 and passes downward from the through hole 14, and then uses auxiliary equipment to lift the column 1 from the horizontal state to the vertical state, and let the guide groove 5 of the column 1 cooperate with the guide block 6 of the cable mounting seat 4 to complete the installation of the cable mounting seat 4 on the column 1. During this process, the staff tightens the pull rope 12 to make it close to the fixed pulley 11 to prevent it from detaching.

[0015] After that, the vertical column 1 is installed on the base 2. The subsequent staff pulls the pull rope 12 downward on the ground to drive the cable mounting seat 4 equipped with the cable and the bird-repelling mechanism to rise vertically on the column 1. After the cable mounting seat 4 moves up to contact with the limit top plate 3, it means that it has moved to the specified height position. The mounting seat locking mechanism locks the cable mounting seat 4 on the column 1 to complete the installation. In the above process, the cable will not be separated from the cable mounting seat 4, and the specified length distance between the two columns 1 can be maintained, avoiding the cable from twitching in the opposite direction due to friction.

[0016] Furthermore, in order to avoid interference with the cable mounting seat 4 during the upward installation process and to lock the cable mounting seat 4 on the column 1, the mounting seat locking mechanism includes an annular groove 15 provided on the outer circumference of the column 1, and a plurality of locking units are arranged on the inner circumference of the annular groove 15. Each locking unit includes a horizontally arranged hinge shaft 16, on which a rotatable support plate 17 is mounted, and a first spring 18 is arranged between the upper end of the support plate 17 and the annular groove 15, and the first spring 18 always has a tendency to rotate the upper end of the support plate 17 out of the annular groove 15.

[0017] When the cable mounting seat 4 moves upward along the column 1, it can overcome the elastic force of the first spring 18 to push the upper end of the support plate 17 into the annular groove 15. When the cable mounting seat 4 moves upward to the position of the limiting top plate 3, the cable mounting seat 4 is separated from the support plate 17. Under the elastic force of the first spring 18, the upper end of the support plate 17 rotates out of the annular groove 15, and the cable mounting seat 4 falls onto the support plate 17 under the action of gravity. The above-mentioned structure does not interfere with the vertical upward movement of the cable mounting seat 4, and after the cable mounting seat 4 moves to the specified height position, the support plate 17 that is moved out of the annular groove 15 again can also provide limiting support for the cable mounting seat 4, so as to realize the locking installation of the cable mounting seat 4 on the column 1.

[0018] Furthermore, the upper part of the inner circumference of the cable mounting seat 4 and the column 1 is provided with an annular bevel 19. When the cable mounting seat 4 moves upward along the column 1, the annular bevel 19 preferentially contacts the support plate 17 located outside the annular groove 15. The inclination of the annular bevel 19 can be consistent with the inclination angle of the support plate 17. The setting of the annular bevel 19 can enable the cable mounting seat 4 to achieve matching abutment with the support plate 17 protruding from the annular groove 15 during the upward movement, and the contact area is larger, which is convenient for overcoming the elastic force of the first spring 18 to squeeze the support plate 17 into the annular groove 15, effectively reducing the contact friction between the cable mounting seat 4 and the support plate 17 during the upward movement, and greatly reducing the influence of the support plate 17 on the upward movement of the cable mounting seat 4.

[0019] Furthermore, in order to allow the cable mounting seat 4 that falls back under the action of gravity to be more stably positioned in coordination with each support plate 17, a limiting protrusion 20 is provided on the top of the support plate 17, and a limiting groove 21 that cooperates with the limiting protrusion 20 is provided on the bottom surface of the cable mounting seat 4. The cooperating limiting protrusion 20 and the limiting groove 21 can realize the positioning and support of the cable mounting seat 4 on the support plate 17, and can avoid the cable mounting seat 4 from rotating relative to the column 1 after the installation is completed.

[0020] When the erection of the column 1 at one location is completed, the subsequent erection operation will involve the installation of the same group of cables in the subsequent length direction and the vertical ascent operation, which will affect the installation stability of the cables on the previous column 1 during the operation. To solve the above problem, the cables on the cable mounting seat 4 can be in a stable locked state after the erection is completed, which can be used as the cable line node for the next construction, and the movement of the cables during the next construction process will not affect the previous column 1 that has been erected. Corresponding to the position of each cable anti-slip mechanism, a cable locking mechanism is installed on the cable mounting seat 4, which can lock and fix the cables at both ends of the cable anti-slip mechanism on the cable mounting seat 4.

[0021] The cable locking mechanism includes a first bending frame 24 arranged on the front side of the clamping frame 7 and a second bending frame 25 arranged on the rear side of the clamping frame 7. The first bending frame 24 and the second bending frame 25 are arranged in a mirror image. The two bending frames, one in front and one behind, one on the left and one on the right, can form a surrounding restriction on the cable to avoid unnecessary movement of the cable after installation.

[0022] In order to realize the compression and positioning of the cable on the cable mounting seat 4, the first bending frame 24 and the second bending frame 25 are extended into the bottom end of the cable mounting seat 4 and are connected with a synchronous plate 26. The cable mounting seat 4 is provided with a vertical groove that cooperates with the synchronous plate 26. When the synchronous plate 26 moves in the vertical groove, it can drive the first bending frame 24 and the second bending frame 25 to rise and fall vertically synchronously, that is, the synchronous plate 26 moves downward, and the first bending frame 24 and the second bending frame 25 press the cable downward, so that the shape of the cable is deformed within the tolerance range and is pressed and locked on the cable mounting seat 4.

[0023] In order to maintain the compressed state of the cable, a locking block 27 is installed at the bottom of the synchronous plate 26. The locking block 27 is provided with a horizontally arranged locking hole 28, and the locking block 27 can pass downward through the cable mounting seat 4. When the cable is placed in the first bending frame 24 and the second bending frame 25, the cable contacts the inner wall of the bending frame. At this time, the cable is not compressed and has not deformed. The locking hole 28 on the locking block 27 is located in the cable mounting seat 4. If the first bending frame 24 and the second bending frame 25 move downward to compress and squeeze the cable, the cable is deformed, the locking block 27 moves downward synchronously, and the locking hole 28 on the locking block 27 also extends out of the cable mounting seat 4.

[0024] Corresponding to the position of the locking block 27, a locking pin sleeve 29 is provided at the bottom of the cable mounting seat 4, and a locking pin 31 is connected to the locking pin sleeve 29 through a second spring 30. The second spring 30 always has a tendency to push the locking pin 31 close to the locking block 27. A hanging ring 32 is provided at the bottom of the locking block 27. When the hanging ring 32 is pulled to drive the locking block 27 to move downward, the first bending frame 24 and the second bending frame 25 can press the cable downward onto the cable mounting seat 4, and at the same time, the locking hole 28 on the locking block 27 moves downward out of the cable mounting seat 4. Under the elastic force of the second spring 30, the locking pin 31 enters the locking hole 28 to achieve the first bending frame 24 and the second bending frame 25 to maintain the locking state of the cable.

[0025] When the above structure is in overall construction operation, the cover plate 10 is first opened, and the cable is adapted and bent according to the shape of the bending frame, and then the cable is placed between the clamping roller 8 and the first bending frame 24 and the second bending frame 25, and the cover plate 10 is closed. At this time, the gravity of the first bending frame 24 and the second bending frame 25 is not enough to compress and deform the cable, and the locking hole 28 on the locking block 27 is still located in the vertical groove of the cable mounting seat 4, and the locking pin 31 contacts the side wall of the locking block 27 and does not enter the locking hole 28. After the cable mounting seat 4 is moved up to the specified height position, it is necessary to adjust the bending frame to compress and lock the cable. At this time, the staff on the ground can use a long pole with a hook to hook the hanging ring 32 at the bottom of the locking block 27 and pull it downward, so that the first bending frame 24 and the second bending frame 25 can compress the cable downward. When the above two bending frames move downward, the locking hole 28 on the locking block 27 will also move out of the cable mounting seat 4, and the locking pin 31 will enter the locking hole 28 to maintain the compression and locking state of the cable. Repeatedly pulling the hanging ring 32 at the bottom of each locking block 27 can realize the compression and locking of the cable by all cable locking mechanisms on the cable mounting seat 4.

[0026] Furthermore, in order to prevent the cables on the cable anti-slip mechanism and the cable locking mechanism from being in the same straight line when locked, and to allow the locking limit of the cable on the cable mounting seat 4 to be subjected to the effects of multiple directional forces, and to avoid the stability reduction caused by a single locking force, so as to achieve a more stable matching locking limit, a boss 33 is provided at the bottom of the clamping frame 7, and a horizontally arranged roller 34 is provided on the boss 33, and the roller 34 can support the bottom of the cable. The cable is located at the bottom of the first bending frame 24, the upper side of the roller 34, and the bottom of the second bending frame 25. When the first bending frame 24 and the second bending frame 25 lock the cable on the cable mounting seat 4, the cable is in a bent and locked state, and the bending frames on both sides form a more stable compression and locking limit for the cable, which can serve as two stable force nodes of the cable, and the influence on the cables suspended on either side will not cause mutual interference, thereby ensuring the stability of the erected column 1 and the cables thereon during the continuous erection of the cable.

[0027] Furthermore, the bird-repelling mechanism includes a rotatable reflector 35 and a bird-repelling spike 36. The reflector 35 can continuously change the angle of reflected light during rotation, and the bird-repelling spike 36 can prevent birds from stopping or nesting on the cable mounting seat 4, thereby achieving the corresponding bird-repelling purpose.

[0028] The bottom of the fixed pulley 11 is fixed to the cable mounting seat 4 through a rotating seat 37. Horizontally arranged reflectors 35 are installed on both sides of the wheel frame of the fixed pulley 11. The reflectors 35 can rotate horizontally with the fixed pulley 11. In the case of wind, the reflectors 35 can continuously rotate to change the angle of reflected light.

[0029] A vertically arranged bracket plate 38 is installed on the cable mounting seats 4 on both sides of the fixed pulley 11, and a detachable shaft rod 39 is installed on the bracket plate 38. The shaft rod 39 is horizontally arranged and located at the upper position of the cable anti-slip mechanism. Bird-repellent spikes 36 are provided on the periphery of the shaft rod 39. The bird-repellent spikes 36 cover the cable anti-slip mechanism and the cable mounting seats 4, and the cable passes through the gap between the bird-repellent spikes 36.

[0030] The bird-repelling spike 36 and its shaft 39 can be disassembled and assembled on the bracket plate 38, which will not affect the normal installation of the cable inside the cable anti-drop mechanism. After the cable is installed, the bird-repelling spike 36 and its shaft 39 can be installed on the bracket plate 38. The setting of the bird-repelling spike 36 will not affect the normal arrangement of the cable on the cable mounting seat 4, and will not block the normal rotation of the reflector 35.

[0031] The rotating seat 37 arranged at the bottom of the fixed pulley 11 allows the fixed pulley 11 to rotate freely. The fixed pulley 11 has two functions. One is to cooperate with the pull rope 12 to drive the cable mounting seat 4 to move up to a specified height position. The second is to drive the reflector 35 to rotate freely after the cable mounting seat 4 is installed in place. As long as the pull rope 12 hung on the fixed pulley 11 is removed after the cable mounting seat 4 is installed in place, the above two functions will not interfere with each other.

[0032] To achieve the above purpose, a guide wheel 22 is provided on the side of the through hole 14 close to the column 1, and a cutter 23 is provided on the side of the through hole 14 away from the column 1. When the pull rope 12 is pulled downward to drive the cable mounting seat 4 to move up along the column 1, the pull rope 12 is close to one side of the guide wheel 22. After the cable mounting seat 4 moves up to the lower side of the limit top plate 3 and is fixed on the column 1, the pull rope 12 is pulled outward to contact the cutter 23, so that the pull rope 12 can be cut and separated on the fixed pulley 11. After losing the restriction of the pull rope 12, the fixed pulley 11 can rotate freely together with the rotating seat 37, thereby realizing the horizontal rotation function of the reflector 35.

[0033] Furthermore, in order to facilitate the adjustment of the direction angle of the cables between different columns 1, so that the erected columns 1 can meet the complex installation conditions on the ground, and better position and guide planning of the suspended cables, the columns 1 can be rotated and adjusted relative to the base 2. To achieve the above purpose, the base 2 is provided with a positioning boss 40, and the bottom of the column 1 is provided with a slot hole that matches the positioning boss 40. A slewing bearing 41 is installed on the base 2 around the positioning boss 40, and the column 1 is located on the slewing bearing 41. The setting of the positioning boss 40 allows the column 1 to be vertically inserted into the base 2 to form a preliminary installation positioning, and due to the setting of the slewing bearing 41, the column 1 can be rotated and adjusted relative to the base 2.

[0034] In order to realize the locking of rotation adjustment, a flange 42 is further provided at the bottom of the column 1, and a plurality of connecting bolts 43 arranged circumferentially are installed on the flange 42. Screw holes arranged circumferentially are opened on the base 2 corresponding to the position of the flange 42. After the connecting bolts 43 fit into the screw holes, the rotation locking between the column 1 and the base 2 can be realized.
