Description

Technical Field

[0001] The invention belongs to the technical field of cable installation, and in particular relates to a guiding device placed inside a cable well and a use method thereof. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Cable stringing is usually the process of installing cables on buildings through brackets, supports, hangers and other facilities. In the construction of power systems, cable stringing is a common construction method, especially in areas such as cities and industrial areas where a large number of cables need to be laid. In the actual cable stringing installation and cable laying construction process, many times the cables not only need to be routed along the walls, but also need to be transferred from the ground to the underground pipes. According to the cable laying construction method, a special cable well is generally set up to cooperate with the underground pipeline as a long-distance cable routing construction.

[0004] When routing cables in a cable well, a cable bracket is usually set up to achieve routing. However, the internal space of a cable well is different from that of a cable trench. The internal space of a cable well is relatively narrow, and the cable bracket cannot be used in the cable well. Some guide devices are set up for routing cables inside the cable well, but the routing position cannot be effectively adjusted. However, obstacles such as climbing frames are usually set up inside the cable well, so the routing position needs to be adjusted to a certain extent to avoid obstacles. In addition, the current guide devices are applicable to a single type of cable.

[0005] Ventilation holes are usually set in cable wells to keep the air in the well fresh and reduce pollutants and humidity in the air. If a fire occurs in the cable well, the current cable holders can hardly effectively prevent the fire from spreading to the outside through the ventilation holes of the cable well. In addition, the cables in the cable holders are clamped, and the heat is not easy to dissipate. If overheating and spontaneous combustion occur, the fire cannot be extinguished in time.

[0021] Finally, the cable is passed through the wiring restraint device, and the cable is clamped by the wiring restraint device to guide the cable routing.

[0022] Compared with the prior art, the present invention has the following advantages and positive effects:

[0023] The present invention is provided with a first cable guiding unit and a second cable guiding unit, which provide guidance for the routing of cables in the cable well, so that the cables can be laid in the horizontal cavity and the vertical cavity of the cable well, and can provide guidance for the routing of cables at the intersection of the horizontal cavity and the vertical cavity, thereby ensuring the stability of the cables after installation.

[0024] The present invention is provided with an adjustment device, which drives the first gear to rotate by twisting the rotating rod, the first gear drives the second gear to rotate, the second gear drives the lifting screw to rotate, the lifting screw rotates to move the lifting frame up and down, and then the wiring constraint device set on the mounting frame moves up and down, thereby realizing the position adjustment of the wiring constraint device, and then the wiring position of the cable can be adjusted, thereby ensuring the accuracy of the cable routing position.

[0025] The present invention provides a protective device, which connects the baffle plate and the inner surface of the first frame through an adhesive layer. The tension spring is in a tensioned state.

An expansion airbag is also provided. When the cable clamping position is overheated and self-ignites, the expansion airbag expands due to the heat, fills the gap between the clamping parts and the gap between the clamping parts and the second frame, and extinguishes the flame. When the temperature is too high and the expansion airbag ruptures, the dry powder filled in the expansion airbag bursts onto the cable, that is, the impact force of the burst is used to make the dry powder fall on the cable to achieve fire extinguishing, and the flame is extinguished in time, thereby further preventing the spread of fire.

[0026] The present invention is provided with a routing constraint device, which drives the adjustment screw to rotate by twisting the adjustment handle, thereby causing the first moving block and the second moving block to move. Since the internal threads of the threaded holes of the first moving block and the second moving block have different rotation directions, the adjustment screw drives the first moving block and the second moving block to move in opposite directions, so that the clamping parts on the first moving block and the second moving block are brought together to clamp the cable, and different types of cables can be clamped to provide constraints for the routing of different types of cables. The clamping effect is improved by the auxiliary clamping device, and the clamping part is more closely fitted to the cable surface when clamping, which is suitable for clamping cables of smaller sizes, and can play a better clamping role. The front and rear positions of the cable can be adjusted according to different clamping positions, and the cable position can be adjusted in multiple directions in the cable well in cooperation with the adjustment device, so that the cable routing position can be accurately adjusted, avoiding obstacles on the cable routing path, and the cable position can be reasonably adjusted according to the routing needs of the cable.

[0042] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0043] Embodiment 1:

[0044] The present invention is described in detail below in conjunction with the accompanying drawings. This embodiment discloses a guiding device placed inside a cable well, such as Figure 1 As shown, it includes a first cable guiding unit 2 and a second cable guiding unit 3. The first cable guiding unit 2 is arranged in the horizontal well cavity and the vertical well cavity of the cable well 1, and a plurality of the first cable guiding units 2 are arranged at intervals; the second cable guiding unit 3 is arranged at the intersection of the horizontal well cavity and the vertical well cavity of the cable well 1, and the first cable guiding unit 2 cooperates with the second cable guiding unit 3 to realize the guidance of the cable when it is routed;

[0045] The first cable guide unit 2 includes an adjustment device, which includes a mounting frame 210, a protective device 201 is provided at one end of the mounting frame 210, and a wiring restraint device 202 is provided at the other end of the mounting frame 210. The protective device 201 and the wiring restraint device 202 are installed on the mounting frame 210, and the mounting frame 210 is a right-angled triangle structure as a whole, and the protective device 201 and the wiring restraint device 202 are respectively installed on the vertical sides of the mounting frame 210.

[0046] The first cable guide unit 2 and the second cable guide unit 3 are used to guide the installation of the cable in the cable well 1, so that the cable is laid in the laying direction required for installation, and the accuracy of the laying direction is ensured; the routing constraint device 202 of the guide unit is used to fix the cable, that is, to constrain the position of the cable to prevent the cable from moving after laying; the protective device 201 is used to prevent the spread of flames, that is, to protect against the spread of fire. The cable routing position is adjustable through the adjustment device, that is, the cable routing position is fine-tuned to avoid the position deviation causing the cable angle to tilt, and ensure the accuracy of the cable routing position; when in use, the cable routing direction is first preliminarily guided by the first cable guide unit 2 and the second cable guide unit 3, and then fine-tuned by the adjustment device.

[0047] like Figure 2As shown, the adjustment device also includes a housing 203, which is arranged on the inner wall of the well cavity of the cable well 1; a first gear 205 is arranged inside the housing 203, and the first gear 205 is sleeved on the rotating rod 204; one end of the first gear 205 is meshed with the second gear 206, and the second gear 206 is sleeved on the lifting screw 207. A threaded hole is arranged on the lower surface of the mounting frame 210, and one end of the lifting screw 207 passes through the upper part of the housing 203 and the threaded hole of the mounting frame 210 in sequence; one end of the mounting frame 210 is connected to the supporting frame 209, and one end of the supporting frame 209 is connected to the mounting frame 210.

[0048] When in use, the rotating rod 204 is turned. To facilitate turning, the end of the rotating rod 204 can be set in the shape of a hexagonal nut, which makes it easier for the operator to turn the rotating rod 204 with a wrench. The rotation of the rotating rod 204 drives the first gear 205 to rotate, and the first gear 205 drives the second gear 206 to rotate. The first gear 205 and the second gear 206 are both bevel gears, and the force transmission direction is changed by the cooperation of the two. The rotation of the second gear 206 drives the lifting screw 207 to rotate, and the rotation of the lifting screw 207 causes the lifting frame 208 to move up and down. A limiting structure is set on the side of the lifting frame 208, such as a slideway, so that the lifting frame 208 can be lifted and lowered along the slideway to prevent the lifting frame 208 from rotating with the lifting screw 207. The lifting of the lifting frame 208 drives the mounting frame 210 to move up and down. The position of the mounting frame 210 can be adjusted through the adjustment device to achieve the lifting of the mounting frame 210, thereby driving the lifting of the routing constraint device 202, so that the routing constraint device 202 can adjust its position according to the routing conditions of the cables in the cable well 1, thereby better providing guidance for the cable routing.

[0049] like Figure 1 As shown, the protective device 201 of the first cable guiding unit 2 is arranged in the vertical direction or the horizontal direction, and the routing constraint device 202 of the first cable guiding unit 2 is arranged in the vertical direction or the horizontal direction; the routing constraint device 202 of the second cable guiding unit 3 is arranged in the horizontal direction and the vertical direction.

[0050] The first cable guide unit 2 is arranged in the horizontal cavity and the vertical cavity of the cable well 1. The protective device 201 of the first cable guide unit 2 is arranged in the vertical direction in the vertical cavity, and the protective device 201 of the first cable guide unit 2 is arranged in the horizontal direction in the horizontal cavity. The routing restraint device 202 of the first cable guide unit 2 is arranged in the horizontal direction in the vertical cavity, and in the vertical direction in the horizontal cavity. The first cable guide unit 2 provides guidance for the cable in the horizontal and vertical directions in the cable well 1. In case of fire, the ventilation holes can be closed in time to prevent the flame from spreading.

[0051] The second cable guide unit 3 is arranged at the intersection of the horizontal cavity and the vertical cavity, one routing constraint device 202 of the second cable guide unit 3 is arranged in the vertical direction in the horizontal cavity, and the other routing constraint device 202 is arranged in the horizontal direction in the vertical cavity. When the cable routing encounters a bend, the second cable guide unit 3 provides guidance for the cable at the turning position.

[0052] like Figure 8 As shown, the protective device 201 includes a first frame 2011, a first mounting bolt 2012 is disposed on the outer surface of the upper end of the first frame 2011, and a spring mounting seat 2013 is disposed on the lower end of the first frame 2011. The spring mounting seat 2013 is connected to one end of a tension spring 2014, and the other end of the tension spring 2014 is connected to one end of a shielding plate 2015; the other end of the shielding plate 2015 is connected to an adhesive layer 2016, and the adhesive layer 2016 is used to bond the shielding plate 2015 to the inner surface of the upper end of the first frame 2011.

[0053] The shielding plate 2015 and the first frame 2011 are bonded by an adhesive layer 2016, and the adhesive layer 2016 can be made of hot melt adhesive or other colloids that melt with residual heat. When a fire occurs, the temperature rises and the hot melt adhesive melts. Under the action of the tension spring 2014, the shielding plate 2015 is pulled to block the vent 4 on the side wall of the cable well 1 to prevent the flame from spreading.

[0054] like Figure 4 As shown, the wiring restraint device 202 includes a second frame 2021, and a second mounting bolt 2022 is provided on the outer surface of one end of the second frame 2021; an adjusting screw 2023 is provided inside the second frame 2021, and a plurality of adjusting screws 2023 are provided at intervals, one end of the adjusting screw 2023 is movably connected to the inner surface of the second frame 2021, and the other end passes through the second frame 2021 and is connected to the adjusting handle 2024. External threads are provided at intervals on the adjusting screw 2023, and are divided into a plurality of thread segments; a first moving block 2025 and a second moving block 2026 are provided on the thread segments, and a left-handed internal thread is provided in the threaded hole of the first moving block 2025, and a right-handed internal thread is provided in the threaded hole of the second moving block 2026. A clamping member 2029 is provided on the first moving block 2025 and the second moving block 2026 ; a limiting rod 2028 is provided at the lower end of the adjusting screw 2023 , and the limiting rod 2028 penetrates the first moving block 2025 and the second moving block 2026 ; both ends of the limiting rod 2028 are fixedly connected to the inner surface of the second frame 2021 .

[0055] like Figure 4As shown, a plurality of airbag fixing plates 2030 are arranged at intervals in the second frame 2021, and the airbag fixing plates 2030 are fixedly connected to the second frame 2021; an expansion airbag 2031 is arranged at the end of the airbag fixing plate 2030, and the expansion airbag 2031 is fixedly connected to the airbag fixing plate 2030, and the interior of the expansion airbag 2031 is filled with dry powder; the airbag fixing plate 2030 is at the upper end of the clamping member 2029. The airbag fixing plates 2030 are installed on the second frame 2021 at intervals, and the airbag fixing plates 2030 are used to install the expansion airbag 2031, and the expansion airbag 2031 will expand when heated. When the cable is working, the temperature may be too high, and then it may spontaneously combust. It may also be affected by external factors and spontaneously combust. At this time, the expansion airbag 2031 expands due to the heat. As the expansion airbag 2031 expands, the gaps between adjacent clamps, the gaps between opposite clamps, and the gaps between the clamps 2029 and the inner wall of the second frame 2021 are filled with the expansion airbag 2031, and the flame can be extinguished. The expansion airbag 2031 can be made of high-temperature resistant materials, so that it can continue to expand in a high-temperature environment without being burned. When the temperature is too high, exceeding the tolerance limit of the expansion airbag 2031, the dry powder inside the expansion airbag 2031 bursts out and bursts onto the cable. The impact force of the burst is used to make the dry powder fall on the cable to extinguish the fire, thereby preventing the fire from spreading.

[0056] When in use, the adjustment handle 2024 is turned. The adjustment handle 2024 can be set to a hexagonal nut structure, which is convenient for twisting with a wrench. The adjustment handle 2024 rotates to rotate the adjustment screw 2023, thereby moving the first moving block 2025 and the second moving block 2026. A set of the first moving block 2025 and the second moving block 2026 is set on each threaded segment. Since the internal thread rotation directions of the threaded holes of the first moving block 2025 and the second moving block 2026 are different, the adjustment screw 2023 rotates to drive the first moving block 2025 and the second moving block 2026 to move in opposite directions, so that the clamping members 2029 on the first moving block 2025 and the second moving block 2026 are brought together. The clamping member 2029 is a semicircular structure. After closing and closing, the cable can be clamped to achieve cable clamping and provide constraints for cable routing. The clamping method can be applied to more types of cables and achieve cable clamping of different types.

[0057] like Figure 5As shown, an auxiliary clamping device 2027 is arranged on the inner side of the clamping member 2029, and the auxiliary clamping device 2027 includes a fixed plate 20271, one end of the fixed plate 20271 is connected to the inner surface of the clamping member 2029, the other end of the fixed plate 20271 is connected to one end of the arc-shaped rack 20272, a moving plate 20273 is arranged on the other end of the arc-shaped rack 20272, and a clamping plate 20274 is arranged on one end of the moving plate 20273; The other end of the plate 20273 is a hollow structure, in which an axle 20277 is arranged, on which movable gears 20276 are arranged at intervals, and the movable gears 20276 are meshed with the arc-shaped rack 20272; limit blocks 20278 are arranged at the upper and lower ends of the arc-shaped rack 20272, and guide slides 20275 are arranged at the front and rear ends of the arc-shaped rack 20272, and the front and rear ends of the movable plate 20273 are located in the guide slides 20275.

[0058] The function of the auxiliary clamping device 2027 is to improve the clamping effect, and cooperate with the clamping piece 2029 to fit more closely to the cable surface during clamping, thereby achieving a better clamping effect; when in use, the arc-shaped rack 20272 is engaged with the moving gear 20276 to drive the moving plate 20273 to move, wherein the moving plate 20273 is an arc-shaped plate, the axle 20277 passes through the moving gear 20276 and is fixedly connected to the moving gear 20276, and the two ends of the axle 20277 are movably connected to the inner wall surface of the hollow position of the moving plate 20273, and the moving gear 20276 rotates along the arc-shaped rack 20272, thereby driving the axle 20277 to rotate to move the moving plate 20273, and because the moving gear 20276 is engaged with the arc-shaped rack 20272 , so that the movable plate 20273 can be maintained in the position after movement; the guide slide 20275 provides guidance for the movement of the movable plate 20273 to ensure the accuracy of the moving direction, and a limit block 20278 is set to prevent the movable plate 20273 from moving out of the arc-shaped rack 20272; the clamping plate 20274 is fitted with the cable surface, wherein the curvature of the clamping plate 20274 is set smaller than the curvature of the clamping member 2029, which enables the clamping plate 20274 to better fit the cable surface and is more suitable for cables of smaller sizes, and the position of the clamping plate 20274 is movable through the cooperation of the moving gear 20276 and the arc-shaped rack 20272, and then the position of the clamping plate 20274 is appropriately adjusted according to the position of the cable to achieve a better clamping effect.

[0059] like Figure 6As shown, the movable plate 20273 is at one end of the arc-shaped rack 20272, and the clamping member 2029 clamps and drives the clamping plate 20274 to fit the cable surface. The cable in the figure is a small cable. If such a cable is clamped by the clamping member 2029, the clamping member 2029 cannot fit the cable surface, which affects the cable routing. The clamping plate 20274 can fit the cable surface with a small size to achieve clamping. And the position of the clamping plate 20274 can be adjusted, such as Figure 7 As shown, the clamping plate 20274 is at the other end of the arc-shaped rack 20272. At this time, the cable is also clamped by the clamping plate 20274, which is suitable for clamping cables of smaller sizes; and when the clamping position of the cable is different, the routing position of the cable will also be different, that is, the front and rear position adjustment of the cable during routing is realized, and the clamping effect at the front and rear positions is guaranteed, and then the front and rear and left and right positions of the cable in the cable well are adjusted in cooperation with the adjustment device, so that the cable routing position can be accurately adjusted, avoiding obstacles on the cable routing path, and can be reasonably adjusted according to the routing needs of the cable.

[0060] Embodiment 2:

[0061] A method for using a guiding device placed inside a cable well as described in Example 1 comprises the following steps:

[0062] The adjustment device of the first cable guide unit 2 is installed at intervals on the inner wall surface of the vertical well cavity of the cable well 1 and the inner wall surface of the horizontal well cavity of the cable well 1; the adjustment device of the second cable guide unit 3 is installed on the inner wall surface of the vertical well cavity of the cable well 1;

[0063] Then, the wiring restraint device 202 of the first cable guide unit 2 and the second cable guide unit 3 is vertically or horizontally mounted on the mounting frame 210 of the adjustment device; the position of the wiring restraint device 202 is adjusted by the adjustment device, and after the adjustment is completed, the protective device 201 is vertically or horizontally mounted on the mounting frame 210 of the first cable guide unit 2;

[0064] The installation of the protective device 201 requires that the ventilation opening layout area 5 is aligned with the ventilation opening 4 on the side wall of the cable well 1, and ensure that the shielding plate 2015 is in close contact with the inner wall surface of the cable well 1. It can be seen that the shielding plate 2015 is set as a square plate or an arc plate, which is in close contact with the inner wall surface of the cable well 1.
