Description

Technical Field

[0001] This application relates to the field of roof mast technology, and in particular to a stable installation structure for a roof mast. Background Technology

[0002] A mast is a tall column on a ship that holds sails and flags, mounts antennas, and supports observation posts. It is a long, round wooden pole or a metal column that usually rises vertically from the keel or midships and can support the barges, sail girder, derrick, or girder.

[0003] Nowadays, masts are not only used on ships, but also installed on the roofs of some buildings. Because masts are relatively tall and installed on roofs, they are difficult to keep stable in windy weather conditions, which can create danger. Summary of the Invention

[0004] To improve mast stability, this application provides a stable installation structure for a roof mast.

[0005] The stable installation structure for a roof mast provided in this application adopts the following technical solution:

[0006] A stable installation structure for a roof mast includes a mast body and a plurality of first cables circumferentially arranged outside the mast. The mast is hollow, and an inspection door is provided at the lower end of the mast. The mast is provided with a plurality of second cables for reinforcement, the second cables extending from the inside of the mast to the outside of the mast. A mounting frame is fixed to the inner wall of the upper end of the mast, and a transmission rod is rotatably connected to the mounting frame. The mast is provided with a drive assembly for driving the transmission rod to rotate. The mounting frame is provided with a winding assembly for winding the second cables. The winding assembly obtains power through the transmission rod. A locking assembly for locking and positioning the second cables is provided inside the mast. The mounting frame is provided with a guide assembly for driving the locking assembly to lock. A fixing assembly is provided at the end of the second cable away from the mast.

[0007] By adopting the above technical solution, the stability of the mast is further improved by using several second cables in severe weather. The drive assembly drives the transmission rod to rotate, and the rotation of the transmission rod provides power to the winding assembly and the guide assembly, so that the winding assembly can wind or unwind the second cables. At the same time, the guide assembly drives the locking assembly to lock the second cables when they are unwound and to release them when they need to be wound. The second cables are fixed by the fixing assembly, which improves the stability of the mast.

[0008] Optionally, the drive assembly includes a drive motor fixed to the inner wall of the mast, a worm gear fixed to the output shaft of the drive motor, and a worm wheel coaxially fixed to the transmission rod, wherein the worm gear meshes with the worm wheel.

[0009] By adopting the above technical solution, the drive motor rotates, which drives the worm gear to rotate, thereby driving the worm wheel to rotate, and in turn driving the transmission rod to rotate.

[0010] Optionally, the winding assembly includes a first gear coaxially fixed to the transmission rod, a plurality of rotating rods rotatably connected to the mounting frame, a plurality of second gears coaxially fixed to the plurality of rotating rods, and a winding roller coaxially fixed to the rotating rods, wherein the plurality of second gears are arranged circumferentially along the first gear and all mesh with the first gear.

[0011] By adopting the above technical solution, the rotation of the transmission rod drives the first gear to rotate, which in turn drives the second gear to rotate, and then drives the take-up roller to rotate to take up or unwind the second cable.

[0012] Optionally, the locking assembly includes a locking ring slidably connected to the inner wall of the mast, a first locking block fixed to the locking ring, a second locking block fixed to the inner wall of the mast, and a reset member disposed on the inner wall of the mast for resetting the locking ring. The first locking block and the second locking block are respectively located on both sides of the opening where the second cable extends out of the mast. A first sliding member is disposed between the locking ring and the inner wall of the mast to allow the locking ring to slide stably.

[0013] By adopting the above technical solution, when the unwinding is completed, the locking ring rotates through the first sliding member to drive the second locking block to move and cooperate with the first locking block to clamp and lock the second cable, so that the second cable remains stable. When winding, the locking ring is reset by the reset member, so that the second locking block moves away from the first locking block and releases the second cable.

[0014] Optionally, the first sliding member includes a first slider fixed to the inner wall of the mast and a first groove formed in the side wall of the locking ring, wherein the first slider is slidably connected in the first groove.

[0015] By adopting the above technical solution, the first slider is stably slidably connected to the first groove, so that the locking ring can rotate stably.

[0016] Optionally, both the first locking block and the second locking block have arc-shaped grooves on their opposite sidewalls for clamping the second cable.

[0017] By adopting the above technical solution, the arc groove increases the contact area between the first locking block, the second locking block and the second cable, thereby improving the clamping stability.

[0018] Optionally, the guide assembly includes a guide disc coaxially fixed to the transmission rod, a guide hole penetrating the guide disc, a guide rail fixed to the inner wall of the mast, a first push rod slidably connected to the guide rail, a first abutment block slidably connected to the side wall of the mast, a second push rod fixed to the upper surface of the first abutment block, and a second abutment block fixed to the locking ring. The guide hole is spirally arranged, the guide rail is radially arranged along the mast, the first push rod passes through the guide hole and its upper end extends out of the guide hole, a reset member is provided between the first abutment block and the inner wall of the mast, the lower surface of the first abutment block is arc-shaped, the end of the first push rod away from the guide rail slides and abuts against the arc-shaped surface of the first abutment block, the side wall of the second abutment block is arc-shaped, and the second push rod slides and abuts against the arc-shaped surface of the second abutment block.

[0019] By adopting the above technical solution, the guide disc rotates and the guide hole is spirally arranged, causing the first push rod to move along the guide rail. The direction of movement of the first push rod changes according to the rotation direction of the guide disc. During unwinding, the first push rod slides away from the mast axis and abuts against the arc-shaped surface of the first abutment block, thereby lifting the first abutment block. This causes the second push rod to abut against the arc-shaped surface of the second abutment block and slide, thereby causing the second abutment block to move. The movement of the second abutment block drives the locking ring to rotate. At the same time as the second cable is unwound, the locking ring rotates and locks and positions the second cable. During winding, the guide disc reverses, causing the first push rod to leave the first abutment block. The reset component facilitates the reset of the first abutment block, thereby resetting the locking ring and loosening the second cable for easy winding.

[0020] Optionally, the arc-shaped surfaces of the first abutment block and the second abutment block are provided with sliding grooves, and the ends of the first push rod and the second push rod are both hemispherical, with the hemispherical ends of the first push rod and the second push rod slidingly connected in the corresponding sliding grooves.

[0021] By adopting the above technical solution, the end of the first push rod slides better in the sliding groove, and the end of the second push rod slides better in the sliding groove.

[0022] Optionally, the fixing assembly includes a U-shaped plate fixed to the end of the second cable away from the mast, a mounting plate fixed to the ground, a fixing plate fixed to the mounting plate, and a plurality of fixing bolts. The fixing plate is located between the two side plates of the U-shaped plate, and the plurality of fixing bolts pass through the two side plates of the U-shaped plate and the fixing plate.

[0023] By adopting the above technical solution, the U-shaped plate and the fixing plate are fixed with fixing bolts, so that the second cable remains stable, improving the overall stability of the mast and facilitating the disassembly and assembly of the second cable.

[0024] Optionally, the second cable sheath is provided with a protective sleeve, and the mast sidewall has a receiving groove for accommodating the protective sleeve.

[0025] By adopting the above technical solution, the protective sleeve protects the second cable and, when not in use, stores it in the receiving slot, maintaining the aesthetic appearance of the mast.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. In severe weather, the stability of the mast is further enhanced by several second cables; the drive assembly drives the transmission rod to rotate, and the rotation of the transmission rod provides power to the winding assembly and the guide assembly, so that the winding assembly can wind or unwind the second cables. At the same time, the guide assembly drives the locking assembly to lock the second cables when they are unwound, and releases the second cables when they need to be wound up.

[0028] 2. The direction of movement of the first push rod is changed according to the rotation direction of the guide disc. During unwinding, the first push rod slides away from the mast axis and abuts against the arc-shaped surface of the first abutment block, thereby lifting the first abutment block. This causes the second push rod to abut against the arc-shaped surface of the second abutment block and slide, thereby causing the second abutment block to move. The movement of the second abutment block drives the locking ring to rotate. At the same time as the second cable is unwound, the locking ring rotates and locks and positions the second cable. During winding, the guide disc reverses to make the first push rod leave the first abutment block. The reset component facilitates the reset of the first abutment block, thereby resetting the locking ring and loosening the second cable for easy winding. Attached Figure Description

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a stable installation structure for a roof mast. (Refer to...) Figure 1 The system includes a mast body 1 and several first cables 2 arranged circumferentially outside the mast. The first cables 2 are spirally arranged to increase the overall stability and aesthetics of the mast. The mast is hollow, and an inspection door is hinged to the lower end of the mast. The mast is equipped with several second cables 3 for further reinforcement in inclement weather. The second cables 3 are arranged circumferentially around the mast and extend from the inside of the mast to the outside. A fixing component 4 is provided at the end of the second cable 3 away from the mast. The second cables 3 are covered with a protective sleeve 5. A receiving groove 6 is opened on the side wall of the mast to accommodate the protective sleeve 5. When the second cables 3 are not used, the second cables 3 and the protective sleeve 5 are stored in the receiving groove 6 and form a cylinder with the mast to maintain aesthetics.

[0040] Reference Figure 2A mounting bracket 7 is fixed to the inner wall of the upper end of the mast by screws. The mounting bracket 7 is rotatably connected to a transmission rod 8 via bearings. The transmission rod 8 is aligned with the mast axis. A drive assembly 9 is installed inside the mast to drive the transmission rod 8. The mounting bracket 7 is equipped with a winding assembly 10 for winding the second cable 3. A locking assembly 11 is installed inside the mast to lock and position the second cable 3. The mounting bracket 7 is equipped with a guide assembly 12 for driving the locking assembly 11 to lock. In inclement weather, the drive assembly 9 drives the transmission rod 8 to rotate, thereby providing power to the winding assembly 10. The winding assembly 10 releases the second cable 3 to a specified length, which is then secured by personnel. When the second cable 3 is released to the specified length, the guide assembly 12 drives the locking assembly 11 to lock and position the second cable 3, thus maintaining the stability of the second cable 3.

[0041] Reference Figure 3 The drive assembly 9 includes a drive motor 91 fixed to the inner wall of the mast by screws, a worm 92 coaxially welded to the output shaft of the drive motor 91, and a worm wheel 93 coaxially welded to the transmission rod 8. The worm 92 is horizontally arranged and meshes with the worm wheel 93. The controller makes the drive motor 91 rotate and drive the worm 92 to rotate, thereby driving the worm wheel 93 to rotate, and then driving the transmission rod 8 to rotate.

[0042] Reference Figure 4 The winding assembly 10 includes a first gear 101 coaxially welded to the transmission rod 8, several rotating rods 102 rotatably connected to the mounting frame 7 via bearings, several second gears 103 coaxially welded to the rotating rods 102, and a winding roller 104 coaxially welded to the rotating rods 102. One end of the second cable 3 is wound and fixed to the winding roller 104. The several second gears 103 are arranged circumferentially along the first gear 101 and all mesh with the first gear 101. The rotation of the transmission rod 8 drives the first gear 101 to rotate, and the first gear 101 drives the several second gears 103 to move, thereby driving the winding roller 104 to rotate to wind and unwind the second cable 3.

[0043] Reference Figure 5The locking assembly 11 includes a locking ring 111 slidably connected to the inner wall of the mast, a first locking block 112 fixed to the locking ring 111 by screws, a second locking block 113 fixed to the inner wall of the mast by screws, and a reset component disposed on the inner wall of the mast for resetting the locking ring 111. The reset component is a reset spring 13. Both the inner wall of the mast and the locking ring 111 are welded with several baffles 14 along the axial direction. The two ends of the reset spring 13 are respectively welded to the baffles 14 of the inner wall of the mast and the locking ring 111, so that the locking ring 111 is reset by the elastic force of the reset spring 13. The first locking block 112 and the second locking block 113 are located on both sides of the opening where the second cable 3 extends out of the mast. A first sliding member 15 is provided between the locking ring 111 and the inner wall of the mast to stabilize the sliding of the locking ring 111. The first sliding member 15 includes a first slider 151 welded to the inner wall of the mast and a first groove 152 formed in the side wall of the locking ring 111. The first slider 151 is slidably connected in the first groove 152. When it is necessary to clamp and position the second cable 3, the locking ring 111 is driven to slide by the guide assembly 12, which drives the first locking block 112 to move and cooperate with the second locking block 113 to lock and position the second cable 3. The opposite side walls of the first locking block 112 and the second locking block 113 are provided with arc-shaped grooves 16 to increase the contact area with the second cable 3 and facilitate better clamping and positioning of the second cable 3.

[0044] Reference Figure 6The guide assembly 12 includes a guide disc 121 coaxially welded to the transmission rod 8, a guide hole 122 penetrating the guide disc 121, a guide rail 123 welded to the inner wall of the mast, a first push rod 124 slidably connected to the guide rail 123, a first abutment block 125 slidably connected to the side wall of the mast, a second push rod 126 fixed to the upper surface of the first abutment block 125, and a second abutment block 127 fixed to the locking ring 111. The guide hole 122 is spirally arranged, and the first push rod 124 is slidably inserted through the guide rail 123 along the radial direction of the mast. The guide hole 122 extends out of the upper end of the first push rod 124. The lower surface of the first abutment block 125 and the side wall of the second abutment block 127 are both arc-shaped. The arc-shaped surfaces of the first abutment block 125 and the second abutment block 127 are both provided with sliding grooves 17. The upper ends of the first push rod 124 and the second push rod 126 are both hemispherical. The hemispherical ends of the first push rod 124 and the second push rod 126 are slidably connected to the corresponding sliding grooves 17, so that the first push rod 124 and the second push rod 126 can slide more easily in the sliding grooves 17. A reset component, namely a reset spring 13, is provided between the first abutment block 125 and the inner wall of the mast. A baffle 14 is welded to the inner wall of the mast above the first abutment block 125. One end of the reset spring 13 is welded to the baffle 14 and the other end is welded to the upper surface of the first abutment block 125, so that the first abutment block 125 can be reset by relying on the elastic force of the reset spring 13. A second slider 18 is welded to the side of the first abutment block 125 facing the inner wall of the mast. A second sliding groove 19 is provided on the inner wall of the mast for the second slider 18 to slide. The transmission rod 8 drives the guide plate 121 to rotate. The first push rod 124 slides along the guide rail 123 in the guide hole 122, and then abuts against the lower surface of the first abutment block 125 and slides along the arc surface of the first abutment block 125 to push the first abutment block 125 upward. This causes the second push rod 126 to slide on the arc surface of the second abutment block 127, thereby pushing the second abutment block 127 and causing the locking ring 111 to slide, thereby clamping the second cable 3.

[0045] Reference Figure 7 The fixing component 4 includes a U-shaped plate 41 fixed to the end of the second cable 3 away from the mast by screws, a mounting plate 42 fixed to the ground by screws, a fixing plate 43 welded to the mounting plate 42, and several fixing bolts 44. The fixing plate 43 is located between the two side plates of the U-shaped plate 41, and the several fixing bolts 44 pass through the two side plates of the U-shaped plate 41 and the fixing plate 43 to facilitate the fixing of the second cable 3.

[0046] The implementation principle of this application embodiment is as follows: the drive motor 91 is controlled to rotate, and the transmission rod 8 is driven to rotate through the transmission of the worm gear 92 and the worm wheel 93, thereby driving the guide disk 121 and the first gear 101 to rotate; the rotation of the first gear 101 drives several second gears 103 to rotate, thereby driving the winding roller 104 to rotate to unwind the second cable 3; the rotation of the guide disk 121 pushes the first push rod 124 to slide along the guide rail 123, and finally abuts against the arc-shaped surface of the first abutting block 125 and slides along the sliding groove 17 to push the first abutting block 125 upward, thereby causing the second push rod 126 to move upward and slide along the sliding groove 17 on the side wall of the second abutting block 127, pushing the second abutting block 127, and then pushing the locking ring 111 to move. The movement of the locking ring 111 drives the first locking block 112 to move to clamp and fix the second cable 3. The drive motor 91 rotates in the opposite direction, the first locking block 112 moves away from the second locking block 113, and the second cable 3 is released, so that the winding roller 104 winds up the second cable 3.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
