Description

Technical Field

[0001] The invention relates to the technical field of cable laying, in particular to a cable bridge dismantling device. Background Art

[0002] A cable tray is a structure used to support, secure and protect electrical cables. It is usually made of metal or plastic and is designed to provide a safe passage inside or outside a building, allowing cables to be arranged in an orderly manner and protecting them from damage by the external environment.

[0003] The straight section layout of the cable tray is the most common in the installation process, and accounts for most of the workload in the overall installation work. In the prior art, when installing the straight section of the cable tray, a bridging connecting piece is usually used to fix the ends of two adjacent cable trays. The cable tray connecting piece is L-shaped, and a through hole is opened on its side to cooperate with the mounting hole on the side of the cable tray near the end position. During installation, bolts are passed from the inside of the cable tray through the mounting holes of the cable tray and the through holes of the connecting piece, and then the cable tray and the connecting piece are fixedly connected by nuts on the outside of the cable tray, thereby completing the fixed connection between adjacent cable trays.

[0004] However, there are still the following shortcomings when using existing connecting pieces for bridge docking: 1. The bridge needs to be dismantled. For example, the replacement of a new bridge system and changes in the building layout, function or design may require adjustment of cable wiring. The original bridge may no longer be applicable and needs to be dismantled and re-routed. The connecting piece is fixed to the bridge with multiple bolts. Specific tools are required for disassembly, and the bolts may rust and strip, which makes the overall dismantling process cumbersome and time-consuming.

[0005] Second, the cables in the bridge usually need to be limitedly connected to the bridge using cable ties to ensure the orderly distribution of the cables in the bridge. Therefore, when dismantling the bridge, the cable ties between the cables and the bridge need to be cut first, which is labor-intensive and reduces the efficiency of the dismantling work. Moreover, after the bridge is dismantled, the cables lack support and are prone to sagging and entanglement, causing inconvenience to the subsequent processing of the cables.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1: See also Figures 1 to 9 In an embodiment of the present invention, a cable tray dismantling device includes a plurality of connection mechanisms 35 pre-distributed along the straight section layout path of the cable tray 5; the connection mechanism 35 includes a bottom plate 1, and mounting mechanisms 8 are provided at both ends of the bottom plate 1, and two groups of limit mechanisms 7 are symmetrically arranged about the middle position of the bottom plate 1 near the middle of the bottom plate 1; The mounting mechanism 8 includes two limiting slide grooves 10 and a through groove 11 which are provided on the top surface of the base plate 1. The two limiting slide grooves 10 are arranged in parallel at intervals, and the limiting slide grooves 10 are arranged in parallel with the width direction of the base plate 1. The through groove 11 is located in the middle of the two limiting slide grooves 10, and the through groove 11 is arranged in parallel with the limiting slide grooves 10. The mounting mechanism 8 also includes a driving component fixedly mounted on the bottom surface of the base plate 1. The driving component is located directly below the through groove 11. The driving component is transmission-connected with two groups of docking components. The top of the docking component passes through the through groove 11 and extends to the upper part of the base plate 1. The driving component is used to synchronously control the two groups of docking components to move towards or away from each other to cooperate with the docking holes 9 on the bridge frame 5 to complete the disassembly or installation action between the end of the bridge frame 5. The limiting mechanism 7 includes a slide plate 25 that slides through the bottom plate 1, and a pressing plate 16 that is arranged parallel to the bottom plate 1 is fixedly connected to the top of the slide plate 25. The pressing plate 16 and the slide plate 25 form an L-shaped structure. A plurality of limiting components 17 that are arranged in an array along the length direction of the pressing plate 16 are fixedly installed on the top surface of the pressing plate 16; the limiting mechanism 7 also includes an adjusting component that is fixedly installed on the bottom surface of the bottom plate 1, and the adjusting component is transmission-connected to the slide plate 25, and the adjusting component is used to adjust the distance between the pressing plate 16 and the bottom plate 1; A connecting assembly is rotatably mounted on the side of the base plate 1, and the connecting assembly is used to cooperate with the threaded hanging rod to hoist and arrange the equipment body.

[0026] The existing connecting plates for bridge docking still have the following shortcomings: the bridge needs to be dismantled, and the connecting plates are fixedly connected to the bridge by multiple bolts. Specific tools are required for dismantling, and the bolts are likely to rust and strip, resulting in the overall dismantling process being cumbersome and time-consuming. The cables in the bridge usually need to be limitedly connected to the bridge using cable ties to ensure the orderly distribution of the cables in the bridge. Therefore, when dismantling the bridge, the cable ties between the cables and the bridge need to be cut off first, which is labor-intensive and reduces the efficiency of the dismantling work; and after the bridge is dismantled, the cables lack support and are prone to sagging and entanglement, causing inconvenience to the subsequent processing of the cables.

[0027] When the present invention is used: 1. When docking the bridge frame 5, place the end of the bridge frame 5 at the end position of the base plate 1, and then drive the two groups of docking components to move closer together through the driving component, so that the bridge frame 5 is clamped on both sides of the end of the bridge frame 5 by cooperating with the docking holes 9, thereby completing the fixed connection with the bridge frame 5; therefore, when the bridge frame 5 needs to be dismantled, it is only necessary to control the two groups of docking components to move away through the driving component, so as to quickly separate the docking components from the bridge frame 5, thereby solving the problem that the overall dismantling operation process is cumbersome and time-consuming due to the large number of bolts and possible rust and stripping in the installation method using connecting plates and bolts.

[0028] 2. When laying the cables 6, the multiple cables 6 pass through the multiple groups of limiting components 17 respectively, so that the present invention can have a limiting function for the cables 6 in the bridge 5, and can save the operation steps of using cable ties to fix the cables 6 to the bridge 5 and the step of cutting multiple cable ties when removing; the limiting mechanism 7 can press the middle position of the end of the bridge 5 through the setting of the pressure plate 16. Specifically, when installing the bridge 5, the middle position of the end of the bridge 5 is placed between the pressure plate 16 and the top surface of the base plate 1, and then the distance between the pressure plate 16 and the base plate 1 is adjusted by the adjustment component so that the pressure plate 16 presses the bridge 5. This setting can keep the middle part of the bridge 5 parallel to the base plate 1, facilitate the alignment of the docking component and the docking hole 9, and continue to limit the bridge 5 in the future, thereby improving the connection stability between the device and the bridge 5.

[0029] When arranging the equipment body, the equipment body is hoisted by the cooperation of the threaded hanger and the connecting assembly; after the bridge 5 is disassembled, the pressure plate 16 maintains the support for the cable 6, and the limit assembly 17 maintains the limit for the cable 6, so after the bridge 5 is removed, the cable 6 can remain in an orderly state, avoiding the cables 6 from being entangled or intertwined with each other, which is convenient for subsequent management and maintenance; and with the help of support and limit, the cable 6 is not easily susceptible to external physical damage, pulling or twisting, reducing the risk of accidents and improving the overall safety of the demolition work.

[0030] It should be noted that there is a gap between the end of the bridge frame 5 and the slide plate 25. When disassembling the bridge frame 5, loosen the two ends of the bridge frame 5, then raise the pressure plate 16, and then lift the end of the bridge frame 5 so that the end of the bridge frame 5 can be moved out from between the base plate 1 and the pressure plate 16, thereby facilitating the disassembly of the bridge frame 5 between the two sets of connecting mechanisms 35.

[0031] Therefore, the present invention introduces an innovative design, which can effectively replace the traditional connecting piece by setting the installation mechanism 8 to realize the docking function of adjacent bridges 5. In the docking process, the bridge 5 can be firmly fixed or easily loosened simply by controlling the relative approach or distance of the two groups of docking components, thereby significantly improving the efficiency of bridge disassembly and assembly; and the present invention also includes multiple groups of limit components 17 in the limit mechanism 7, which provide a stable limit function for multiple cables 6. This setting eliminates the tedious steps of fixing the cables with cable ties, simplifies the cable arrangement process, and not only improves the neatness and standardization of cable installation, but also greatly facilitates the disassembly and assembly of the bridge 5, reducing the additional troubles that may be encountered when disassembling and rearranging the cables.

[0032] The driving assembly includes two fixed seats 23 fixedly mounted on the bottom surface of the base plate 1. The two fixed seats 23 are respectively located at two ends of the base plate 1. A bidirectional screw rod 24 is rotatably mounted between the two fixed seats 23. Two sets of docking components are installed on the outer periphery of the bidirectional screw rod 24 through-threadedly, and the two sets of docking components are symmetrically arranged about the middle position of the bidirectional screw rod 24; A knob 26 is fixedly mounted at the middle position of the outer periphery of the bidirectional screw rod 24 .

[0033] The docking assembly includes a connecting block 22, the bottom end of which is threadedly connected to the periphery of the bidirectional screw rod 24, and the top end of the connecting block 22 passes through the through slot 11 at the corresponding position to the top of the bottom plate 1, and the connecting block 22 is in sliding contact with the inner side of the through slot 11; A slide seat 12 arranged parallel to the bottom plate 1 is fixedly mounted on the top of the connecting block 22, a side plate 13 perpendicular to the slide seat 12 is fixedly mounted on the top surface of the slide seat 12 at a position close to the side of the bottom plate 1, and a plurality of clamping columns 14 used in conjunction with the docking holes 9 on the bridge frame 5 are fixedly mounted on the inner side of the side plate 13; Two clamping blocks 21 are fixedly connected to the bottom surface of the slide seat 12 , and the bottom ends of the two clamping blocks 21 are slidably clamped in the two limiting slide grooves 10 respectively.

[0034] When installing the bridge 5, first turn the bidirectional screw rod 24 through the knob 26, and the bidirectional screw rod 24 synchronously drives the two connecting blocks 22 to move closer or farther, so that the distance between the two side plates 13 is adapted to the width of the bridge 5, and then adjust the height of the pressure plate 16 through the adjustment component, so that the distance between the bottom surface of the pressure plate 16 and the top surface of the slide 12 is greater than the thickness of the middle part of the bridge 5; then place the end of the bridge 5 between the two side plates 13, at this time, the bottom surface of the bridge 5 is in contact with the top surface of the slide 12, and then move the bridge 5 so that the middle position of the end of the bridge 5 moves to the pressure plate 16, and then adjust the height of the pressure plate 16 so that the bottom surface of the pressure plate 16 and the bridge 5 are in extrusion sliding contact. At this time, under the limiting action of the pressure plate 16, the bridge 5 and the bottom plate 1 remain parallel, and then the translation of the bridge 5 is finely adjusted so that the docking hole 9 is aligned with the clamping column 14. After the alignment, the two slides 12 are driven to move closer so that the clamping column 14 passes through the docking hole 9 at the corresponding position. At this time, the side plate 13 and the side of the bridge 5 are in extrusion contact, and the clamping column 14 realizes the clamping limit between the side plate 13 and the bridge 5 by passing through the docking hole 9, thereby completing the fixed connection of the end of the bridge 5; When the bridge 5 needs to be removed, the two slides 12 are driven to move away from each other, so that the clamping column 14 is separated from the docking hole 9, and then the slide 12 is separated from the bottom of the bridge 5. After losing the support of the slide 12, the bottom of the bridge 5 will contact the top surface of the bottom plate 1, and the end of the bridge 5 is in a loose state. At this time, the height of the pressure plate 16 is raised to a certain extent, and the end of the bridge 5 can be moved out from between the pressure plate 16 and the bottom plate 1 by tilting the bridge 5. Therefore, during the entire installation and removal process, it is only necessary to move the bridge 5 and turn the knob 26, and there is no need to install multiple bolts and nuts, which provides convenience for the installation and disassembly of the bridge 5.

[0035] In addition, the adjustable distance between the two sets of docking components in the installation mechanism 8 enables the present invention to be applicable to docking installations of different sizes within a certain range, thereby realizing the variable diameter installation of the bridge frame that occurs during the bridge frame laying work, further improving the practicality of the present invention.

[0036] The length of the clamping column 14 is greater than the thickness of the side of the bridge frame 5 , and a sphere is embedded in one end of the clamping column 14 away from the side plate 13 .

[0037] The length of the column 14 is greater than the thickness of the side of the bridge frame 5, but should not be too long to avoid occupying the space in the cable 6. The setting of the sphere can reduce the friction between the front end of the column 14 and the cable 6 during the laying process, thereby reducing the possibility of damage to the cable 6.

[0038] Among them, a tooth 27 used in conjunction with the adjustment component is arranged on the side of the slide plate 25.

[0039] The adjusting assembly includes an L-shaped hanging plate 28 and a mounting seat 32 fixedly mounted on the bottom surface of the base plate 1. Two mounting seats 32 are provided. A driving roller 33 is rotatably mounted between the two mounting seats 32. A second tooth 34 used in conjunction with the first tooth 27 is provided on the periphery of the driving roller 33. The driving roller 33 is meshed with the slide plate 25 through the first tooth 27 and the second tooth 34. One end of the driving roller 33 rotates through the mounting seat 32 at the corresponding position and then is fixedly mounted with the worm gear 31; A worm 30 meshing with a worm wheel 31 is rotatably mounted between the bottom end of the L-shaped hanging plate 28 and the bottom surface of the bottom plate 1 , and a knob 29 is fixedly mounted after the bottom end of the worm 30 rotates through the bottom of the L-shaped hanging plate 28 .

[0040] In the adjustment component, the worm 30 is rotated by knob 29, and the worm 30 drives the driving roller 33 to rotate through the worm wheel 31. The rotation of the driving roller 33 can drive the gear 27 to rise and fall and slide, thereby achieving the purpose of adjusting the distance between the pressure plate 16 and the base plate 1. The worm gear structure is used for adjustment, and its good self-locking ability is used to achieve good stability while having an adjustment function, thereby ensuring the firmness of the pressure plate 16 when limiting the bridge frame 5.

[0041] The limiting assembly 17 includes a vertical plate 19 fixedly mounted on the top surface of the pressure plate 16. A limiting wheel 20 is rotatably mounted on one side of the vertical plate 19 near the top. An annular V-shaped groove is provided in the middle of the periphery of the limiting wheel 20.

[0042] When laying the cable 6, the cable 6 is passed between the limiting wheel 20 and the pressure plate 16. The pressure plate 16 supports the cable 6. The V-shaped groove on the limiting wheel 20 has a limiting effect, thereby achieving the purpose of isolating and limiting multiple cables 6 in an orderly manner.

[0043] Embodiment 2: See also Figure 2 and Figure 3 On the basis of Example 1, the base plate 1 includes two mounting plates, and protrusions 2 are fixedly installed at both ends of the side of one mounting plate, a mounting shaft 15 is rotatably installed between the two protrusions 2, and another mounting plate is fixedly connected to the periphery of the mounting shaft 15, and the two mounting plates are hinged through the protrusions 2 and the mounting shaft 15.

[0044] During the erection of the bridge, there is a need to arrange the cable 6 at an angle. In this embodiment, the hinged setting between the two mounting plates makes the angle between the cables 6 at both ends of the base plate 1 adjustable, thereby meeting the need for the inclined arrangement of the cables 6. Therefore, the present invention can also serve as a docking connector at the bend through this setting, further improving the practicality of the present invention.

[0045] Embodiment 3: See also Figure 3 On the basis of Example 2, the connection assembly includes a connection column 3, and the connection column 3 is rotatably installed at the middle position of both ends of the mounting plate, and a mounting ring 4 is fixedly installed at one end of the connection column 3 away from the mounting plate.

[0046] The bottom end of the threaded hanger passes through the mounting ring 4, and then the lifting of the equipment body is achieved through the limiting of the nut. The angle between the two mounting plates can be controlled and adjusted by controlling the lifting height of the mounting rings 4 on different mounting plates, and the hinged setting of the mounting plates is combined to improve the flexibility of use of the present invention; wherein, the rotational connection between the connecting column 3 and the base plate 1 allows the mounting ring 4 to maintain a horizontal state, thereby facilitating the connection with the threaded hanger and improving installation convenience.

[0047] Embodiment 4: See also Figure 3 On the basis of Example 1, the limiting wheel 20 in the limiting assembly 17 on the other pressing plate 16 is installed on the other side of the vertical plate 19, and the multiple limiting wheels 20 on the two pressing plates 16 are aligned one by one.

[0048] Through this arrangement, after the cable 6 passes through the limiting assembly 17 on the two pressure plates 16, the cable 6 is limited between the two vertical plates 19, thereby improving the ability of multiple cables 6 to maintain a stable isolation and limiting state during the laying and pulling process, and reducing the possibility of the cable 6 moving out from between the limiting wheel 20 and the pressure plate 16.

[0049] Embodiment 5: See also Figure 4 On the basis of Example 3, a slope 18 is provided on the top surface of the pressure plate 16 on the side away from the slide plate 25. The setting of the slope 18 has a smooth transition effect on the movement of the cable 6, avoiding friction damage to the cable 6.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
