Abstract
Description
Technical Field

[0002] Communication pipe is a communication pipeline for laying communication cables, optical cables and other cable equipment. It can not only effectively protect the cables from damage by external environmental pressure, but also facilitate the laying and arrangement of cables and daily maintenance. At present, the laying of outdoor remote communication cables usually uses communication pipes to bury the cable lines in the ground tunnels excavated in the early stage. During the laying process of communication pipes, it is necessary to use the ropes and hooks of the single-arm crane equipment to hang and transport the communication pipes to the inside of the ground tunnel. The hooks of traditional single-arm crane equipment mostly adopt J-shaped hook structures, and the upper end of the J-shaped hook structure remains open. It can be seen that the traditional hook structure is relatively exposed. If the rope is affected by the inertia of movement during the pulling and lifting of the communication pipe, causing the communication pipe to swing greatly, it is very easy to cause the hanging ring structure of the communication pipe to be decoupled from the hook of the single-arm crane equipment, thereby causing the communication pipe to fall to the ground and be damaged. In addition, the rope swings greatly with the communication pipe, and the rope itself will bear greater pulling force, which accelerates the loss of the rope's service life. Utility Model Content

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0024] like Figure 1-Figure 8As shown, the utility model provides a communication pipe lifting and anti-falling device, including a support rod 3; a column 2 is welded to the upper side of the support rod 3, a top frame 1 is welded to the top of the column 2, the top frame 1 is welded to the left and right sides of the guide support rod 4, a wheel frame 10 is welded to the lower side of the support rod 3, and a roller 11 is rotatably connected to the bottom end of the wheel frame 10; it also includes a crossbeam frame 6, a hook device 16 and a displacement motor 18; the front and rear ends of the crossbeam frame 6 are rotatably connected to a sleeve 8, a steel cable 15 is wound around the outer side of the sleeve 8, a lifting ring 17 is installed at the bottom end of the steel cable 15, a pulling motor 7 is connected to the right side of the crossbeam frame 6 by bolts, a sleeve 8 is installed on the motor shaft of the pulling motor 7, a limit rod 12 is hinged on the lower side of the crossbeam frame 6, a sliding rod 13 is slidably connected to the inside of the limit rod 12, and the sliding rod 13 is slidably connected to the inside of the limit rod 12. A slider 14 is hinged at the bottom end of 13; a threaded rod 5 is installed on the motor shaft of the displacement motor 18, and the threaded rod 5 is rotatably connected to the top frame 1; there are two groups of hook devices 16, and each group of hook devices 16 includes a hanger 1601, a hanging rod 1602, a spring 1603, an inner hook 1604 and an outer hook 1605; the hanging rod 1602 is welded to the hanger 1601, and the hanging rod 1602 is inserted into the lifting ring 17; the top end of the spring 1603 is welded with the inner hook 1604, and the bottom end of the spring 1603 is welded with the hanger 1601, and a through hole is provided on the lower side of the hanger 1601; the inner hook 1604 is inserted into the through hole of the hanger 1601, and the inner hook 1604 is hung on the hanging ring on the upper side of the communication cable drainage pipe 9; the top end of the outer hook 1605 is welded to the lower side of the hanger 1601.
[0025] When the utility model is carrying out the hoisting work of the communication cable tube, the outer hooks 1605 of the two sets of hook devices 16 are first hung on the two sets of hanging rings prefabricated on the upper side of the communication cable tube 9, and the hanging ring of the communication cable tube 9 passes through the gap between the J-shaped hook structure of the outer hook 1605 and the bottom of the inner hook 1604, and is hung on the inner side of the inner hook 1604, and then the two sets of pulling motors 7 simultaneously drive the two sets of sleeves 8 to rotate synchronously. At this time, the two sets of steel cables 15 are respectively recovered and wound on the outside of the two sets of sleeves 8. The two sets of steel cables 15 lift the communication cable tube 9 through the hook device 16, and the inner hook 1604 is restrained by the gravity of the communication cable tube 9. The elastic force of the servo spring 1603 moves downward along the through hole of the hanger 1601 until the bottom outer surface of the inner hook 1604 fits into the arc groove of the J-shaped hook structure of the outer hook 1605. At this time, the inner hook 1604 and the outer hook 1605 are closed inside and outside, and the hanging ring of the communication cable tube 9 is locked in the closed structure of the inner hook 1604 and the outer hook 1605 to prevent the communication cable tube 9 from being unhooked and falling. When the communication cable tube 9 is lifted to a suitable height, the displacement motor 18 drives the threaded rod 5 to rotate. Since the outer side threads of the threaded rod 5 are engaged with the threaded through holes of the crossbeam frame 6, the threaded rod 5 drives the crossbeam frame 6 The guide support rod 4 moves horizontally to the left or right, and the crossbeam frame 6 lifts the communication cable tube 9 through the steel cable 15 and the hook device 16. During the lifting process, the slider 14 is nested in the outer side of the steel cable 15 and close to the bottom end of the steel cable 15. The slider 14 cooperates with the limit rod 12 and the slide bar 13 to form a nested telescopic sliding structure to limit the left and right swing of the steel cable 15 of different telescopic lengths, preventing the steel cable 15 from swinging significantly due to the inertia of the movement of the communication cable tube 9, so that the communication cable tube 9 can be lifted stably. When the crossbeam frame 6 lifts the communication cable tube 9 to the upper side of the buried tunnel, the two sets of pulling motors 7 are simultaneously At the same time, the two groups of sleeves 8 are driven to reverse, and the sleeves 8 gradually release the steel cables 15 wrapped around the outer side of the sleeves 8. The two groups of steel cables 15 drive the communication cable pipe 9 to penetrate into the inner side of the tunnel through the hook device 16. When the communication cable pipe 9 contacts the bottom of the pit, the inner hook 1604 loses the influence of gravity, and the spring 1603 pushes the circular baffle at the top of the inner hook 1604, so that the inner hook 1604 moves upward along the through hole of the hanger 1601. At this time, the inner hook 1604 is separated from the outer hook 1605, and finally the hanging ring of the communication cable pipe 9 can be taken out from the separation gap between the inner hook 1604 and the outer hook 1605, thereby completing the lifting of the communication pipe.
[0026] In the disclosed embodiment, a threaded through hole is provided at the center of the left side surface of the beam frame 6, and the outer side surface of the threaded rod 5 is threadedly engaged with the threaded through hole of the beam frame 6. Two groups of through holes are symmetrically provided on the front and rear sides of the threaded through hole of the beam frame 6. The two groups of guide support rods 4 are respectively inserted into the two groups of through holes of the beam frame 6. The displacement motor 18 can drive the beam frame 6 to move left and right along the guide support rod 4 through the threaded rod 5, so that the beam frame 6 can be stably transferred to the top of the tunnel by mounting the communication cable pipe 9 through two groups of steel cables 15, replacing the single-arm rope lifting method, and the lifting of the communication cable pipe 9 is more stable.
[0027] In the disclosed embodiment, a through hole is provided at the center position of the upper side surface of the slider 14, and the steel cable 15 is inserted into the through hole of the slider 14. The steel cable 15 slides up and down in the through hole of the slider 14. The slider 14 limits the steel cable 15 through the hinged slide rod 13 to prevent the steel cable 15 from shaking significantly due to inertia during the left and right movement of the crossbeam frame 6, so that the steel cable 15 can stably lift the communication cable conduit 9 through the hook device 16.
[0028] In the disclosed embodiment, the limiting rod 12 is a cylindrical structure with a circular through hole at the bottom end, and the sliding rod 13 is inserted into the inner side of the cylindrical structure of the limiting rod 12, so that the sliding rod 13 can slide and retract along the limiting rod 12. When the steel cable 15 is extended, the sliding block 14 is always at the bottom end of the steel cable 15, and the sliding rod 13 cooperates with the limiting rod 12 to support and limit the steel cable 15 of the length of the pen holder.
[0029] In the disclosed embodiment, a circular baffle is provided at the top of the inner hook 1604, and a spring 1603 is welded to the lower side of the baffle, so that the spring 1603 elastically supports the inner hook 1604 on the upper side of the hanger 1601. When the prefabricated hanging ring on the upper side of the communication cable tube 9 is sleeved on the inner hook 1604 and the communication cable tube 9 is lifted, the inner hook 1604 overcomes the elastic action of the spring 1603 and moves downward, and the inner hook 1604 and the outer hook 1605 are closed to prevent the hanging ring of the communication cable tube 9 from detaching from the hook device 16 and falling.
[0030] In the disclosed embodiment, the outer hook 1605 is a J-shaped hook structure, and an arc groove is provided on the inner side of the J-shaped hook structure of the outer hook 1605. The outer hook 1605 is distributed on the outer side of the inner hook 1604. When the inner hook 1604 moves downward, the outer surface of the bottom of the outer hook 1605 is embedded in the arc groove of the outer hook 1605, so that the inner hook 1604 and the outer hook 1605 can be stably docked.
[0031] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The pulling motor 7, communication cable pipe 9, and displacement motor 18 used above are all common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.
