Description

Technical Field

[0001] This utility model relates to the field of cable fixing equipment technology, and in particular to a cable guiding device. Background Technology

[0002] When power supply cables are used for gantry crane operations in ports and yards, one end is connected to the crane, and the other end is led to the ground via a cable guide frame. The cable on the ground needs to be fixed and guided by a cable guide device. Because the gantry crane is a rail-based machine, the cable may rotate approximately 180 degrees during operation. Current cable guide devices mostly use binding for fixation. Binding cables cannot rotate, which easily leads to compression and twisting of the cable at the power supply well outlet, causing damage, short circuits, and cable head breakage, reducing the effective length of the cable. Repeated cuts may even render the entire cable unusable.

[0003] To address the aforementioned problems, cable guiding devices have been developed. For example, patent document CN202276105U discloses a cable guiding device for side-mounted cable manholes. This device includes a fixed base with a cable bracket on it. The cable bracket consists of a base with a semi-circular groove and an upper pipe clamp movably connected to the base. A cable conduit is installed inside the cable bracket. The fixed base is fixed to the ground, and the cable passes through the cable conduit. The cable can rotate the cable conduit on the cable bracket to change direction. However, in this design, the connection between the cable bracket and the cable conduit is exposed, making it easy for stones and other impurities to enter between them. This affects the rotation of the cable conduit, increases wear, and also increases the risk of falling objects damaging the cable conduit and cable bracket, potentially leading to cable damage. Utility Model Content

[0004] This utility model addresses the problem in current cable guiding equipment where cable conduits and cable trays are exposed, making them susceptible to damage from impurities or falling objects, thus harming the cable. A new cable guiding device is proposed to address this issue.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a cable guiding device, including a base, a cable sleeve, and a protective housing. The base is provided with a clamping mechanism. The cable sleeve is used to hold the cable. The cable sleeve is provided with a fixed part and a guiding part connected to each other. The clamping mechanism movably clamps the fixed part so that the cable sleeve can rotate relative to the clamping mechanism around a first axis. The guiding part is used to guide the cable. The protective housing is movably connected to the base to cover the clamping mechanism and part of the fixed part.

[0007] Furthermore, the protective housing is provided with a receiving cavity, which is used to accommodate at least the clamping mechanism and part of the fixing part. One end of the protective housing is provided with an opening that communicates with the receiving cavity and faces the base. One end of the protective housing along the first axis is provided with a first clearance groove that communicates with the receiving cavity. The guide part can extend out of the protective housing through the first clearance groove.

[0008] Furthermore, the device also includes a locking assembly, which includes a first locking member and a second locking member. The first locking member includes a locking pin and a locking block, and the second locking member includes a locking plate. One end of the locking pin is connected to the base, and the locking plate is fixedly connected to the protective housing. The locking plate is provided with a locking through groove. When the protective housing is connected to the base, one end of the locking pin passes through the locking through groove and is connected to the locking block. The locking block abuts against the locking plate. The outer dimensions of the locking block are larger than the diameter of the locking through groove, so as to lock the protective housing and the base.

[0009] Furthermore, one end of the protective housing is hinged to the base, and the other end is movably connected through a locking assembly. The first locking member includes a hinge tube body, and the locking pin body includes a hinge part and a locking part. The extension direction of the hinge part and the locking part is perpendicular. The hinge part is hinged to the hinge tube body, and the locking part can pass through the locking through groove and cooperate with the locking block. One end of the locking through groove extends to one end of the locking plate body to form a slotted structure, so that the locking part can rotate into the locking through groove.

[0010] Furthermore, a first annular stop is provided at the end of the fixing part away from the guide part. The first annular stop is arranged around the circumference of the fixing part. The protective shell is provided with a second clearance groove at the end opposite to the first clearance groove. The second clearance groove is connected to the receiving cavity. The end of the fixing part opposite to the guide part can extend out of the protective shell through the second clearance groove, and the diameter of the first annular stop is larger than the diameter of the second clearance groove.

[0011] Furthermore, the guide portion includes a first half-tube and a second half-tube. One end of the first half-tube is fixedly connected to the fixing portion, and the second half-tube can be connected to the first half-tube to form the guide portion.

[0012] Furthermore, the first half-pipe body is provided with first skirt protrusions on both opposite sides along its radial direction, and the second half-pipe body is provided with second skirt protrusions on both opposite sides along its radial direction. When the first half-pipe body and the second half-pipe body are connected, the first skirt protrusions and the second skirt protrusions are matched and connected, and the radial dimensions of the first skirt protrusions and the second skirt protrusions are both greater than the diameter of the first clearance groove.

[0013] Furthermore, the guide section has an arc-shaped structure.

[0014] Furthermore, the clamping mechanism includes a clamping base, which includes a first clamping member and a second clamping member. The first clamping member is fixedly connected to the base. The first clamping member is provided with a first clamping half-groove, and the second clamping member is provided with a second clamping half-groove. The first clamping member and the second clamping member are connected in cooperation so that the first clamping half-groove and the second clamping half-groove form a clamping groove for clamping the fixing part, and the fixing part can rotate within the clamping groove.

[0015] Furthermore, the fixing part is provided with a second annular block and a third annular block in sequence along the first axis direction. The second annular block and the third annular block are both arranged circumferentially along the fixing part, and the clamping seat is stuck between the second annular block and the third annular block. The diameter of the second annular block and the third annular block is larger than the diameter of the clamping groove.

[0016] Furthermore, the first clamping member has mounting grooves at opposite ends, and the mounting grooves have first slots. The second clamping member has mounting blocks at opposite ends, and the mounting blocks have second slots. The mounting blocks are engaged with the mounting grooves. When the first clamping member and the second clamping member are engaged and connected, the first slot and the second slot are connected and engaged through a connecting pin.

[0018] Furthermore, the inner walls of both the first and second clamping half-grooves are movably provided with multiple balls, which are in movable cooperation with the outer surface of the fixing part.

[0019] As can be seen from the above technical solutions, the advantages of this utility model are:

[0020] This utility model fixes the cable head to the ground position by setting a base and a clamping mechanism, and guides the cable through a fixing part and a guide part to ensure that the cable is always in the cable trench when rotating. The cable sleeve protects the cable, effectively reducing the concentrated force on the cable and preventing damage caused by squeezing and twisting when the cable rotates. By setting a protective shell, the clamping mechanism and fixing part are covered inside during use, preventing the connection between the clamping mechanism and the fixing part from being exposed. This effectively prevents solid impurities such as stones from entering the connection point and affecting the relative rotation of the cable sleeve in the clamping mechanism.

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Please see Figures 1-4A cable guiding device includes a base 100, a cable sleeve 200, and a protective housing 300. The base 100 is provided with a clamping mechanism. The cable sleeve 200 is used to at least hold a cable. The cable sleeve 200 is provided with a fixed part 210 and a guiding part 220 connected to each other. The clamping mechanism movably clamps the fixed part 210 so that the cable sleeve 200 can rotate relative to the clamping mechanism around a first axis. The guiding part 220 is used to guide the cable at least. The protective housing 300 is movably connected to the base 100 to cover the clamping mechanism and part of the fixed part 210.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the base 100 is a rectangular plate structure, fixed horizontally to the ground. A clamping mechanism is provided on the upper surface of the base 100. The cable sleeve 200 is a tubular structure. In use, the cable can be passed through the cable sleeve 200, so that the cable sleeve 200 is fitted onto the outer surface of the cable. The cable sleeve 200 includes a fixing part 210 and a guiding part 220 connected in sequence. The cable first passes through the fixing part 210 and is then guided by the guiding part 220. The fixing part 210 is movably clamped by the clamping mechanism, so that the clamping mechanism keeps the cable sleeve 200 in place when clamping it. The cable sleeve 200 can rotate with the cable relative to the clamping mechanism. The first axis can be the axis of the fixed part 210, and the direction of the first axis is the length direction of the base 100. By setting the cable sleeve 200 and the clamping mechanism, the cable is prevented from being easily damaged by squeezing and twisting during rotation. In addition, a protective shell 300 is movably connected to the base 100. During installation, the protective shell 300 can cover the clamping mechanism and the fixed part 210 that is connected to the clamping mechanism, thereby providing a certain degree of protection for the clamping mechanism and the fixed part 210.

[0031] In the above structure, the cable head is fixed to the ground position by setting the base 100 and clamping mechanism, and the cable is guided by the fixing part 210 and the guide part 220 to ensure that the cable is always in the cable trench when rotating, thus facilitating the cable turning. The cable sleeve 200 protects the cable, effectively reducing the concentrated force on the cable and preventing damage due to compression and torsion when the cable rotates. At the same time, the protective shell 300 covers the clamping mechanism and fixing part 210 during use, preventing the connection between the clamping mechanism and fixing part 210 from being exposed. This effectively prevents solid impurities such as stones from entering the connection and affecting the relative rotation of the cable sleeve 200 in the clamping mechanism. It also effectively prevents falling objects from directly hitting the connection and causing deformation, thus affecting the rotation of the cable sleeve 200. This effectively protects the normal turning of the cable sleeve 200 and improves the service life of the device.

[0032] In the specific structure of the protective housing 300, the protective housing 300 is provided with a receiving cavity 310, which is used to at least accommodate the clamping mechanism and part of the fixing part 210. One end of the protective housing 300 is provided with an opening that communicates with the receiving cavity 310 and faces the base 100. One end of the protective housing 300 along the first axis is provided with a first clearance groove 320, which communicates with the receiving cavity 310. The guide part 220 can extend out of the protective housing 300 through the first clearance groove 320.

[0033] In this embodiment, as Figure 3 As shown, the protective housing 300 has a cuboid structure with a hollow interior, forming a receiving cavity 310. The bottom end of the protective housing 300 has an opening communicating with the receiving cavity 310. During installation, the lower end face of the protective housing 300 is connected to the upper end face of the base 100, allowing the clamping mechanism and part of the fixing part 210 to enter the receiving cavity 310 through the opening. The length direction of the protective housing 300 is consistent with the length direction of the base 100, and the height direction of the protective housing 300 is vertical. The length of the protective housing 300... One end of the protective housing 300 is provided with a first clearance groove 320. The first clearance groove 320 is a rectangular groove structure and extends vertically. One end of the first clearance groove 320 extends to the bottom of the protective housing 300 to form a slotted structure. When the protective housing 300 is installed on the base 100, the guide part 220 of the cable sleeve 200 and the cable can extend out of the protective housing 300 through the first clearance groove 320, thereby ensuring that the protective housing 300 protects the clamping mechanism while also ensuring the normal rotation of the cable sleeve 200 and the cable.

[0034] In the connection structure between the protective housing 300 and the base 100, the device also includes a locking assembly, which includes a first locking member 410 and a second locking member 420. The first locking member 410 includes a locking pin 411 and a locking block 412. The second locking member 420 includes a locking plate 421. One end of the locking pin 411 is connected to the base 100. The locking plate 421 is fixedly connected to the protective housing 300. The locking plate 421 is provided with a locking through groove 422. When the protective housing 300 is connected to the base 100, one end of the locking pin 411 passes through the locking through groove 422 and is connected to the locking block 412. The locking block 412 abuts against the locking plate 421. The outer dimensions of the locking block 412 are larger than the diameter of the locking through groove 422 to lock the protective housing 300 and the base 100.

[0035] In this embodiment, as Figure 2 , Figure 3As shown, the protective housing 300 can be connected to the base 100 via a locking assembly. A locking pin 411 is connected to the end side of the base 100 along its width direction. The locking pin 411 extends vertically. Correspondingly, a locking plate 421 is fixed to the end of the protective housing 300. The extension direction of the locking plate 421 is perpendicular to the side of the protective housing 300 and extends horizontally. The locking plate 421 has a vertically penetrating locking groove 422. During installation, when the protective housing 300 is correspondingly installed on the base 100, the locking mechanism is activated. The locking pin 411 can pass through the locking slot 422, and one end of the locking pin 411 passing through the locking slot 422 can be connected to the locking block 412. When locked, the bottom end of the locking block 412 abuts against the locking plate 421. Furthermore, the outer dimensions of the locking block 412 are larger than the diameter of the locking slot 422, thereby effectively fixing the protective housing 300 to the base 100. This connection structure is simple and easy to operate. Moreover, the structure of the locking pin 411 and the locking slot 422 can also provide positioning for the protective housing 300 and the base 100, preventing misalignment. The locking pin 411 can be threaded, and the locking block 412 is also provided with a threaded hole that mates with the threaded structure, thereby realizing the threaded connection between the locking pin 411 and the locking block 412, improving locking stability and connection strength.

[0036] In another connection structure between the protective housing 300 and the base 100, one end of the protective housing 300 is hinged to the base 100, and the other end is movably connected through a locking assembly. The first locking member 410 includes a hinge tube body 413, and the locking pin body 411 includes a hinge part and a locking part. The extension direction of the hinge part and the locking part is perpendicular. The hinge part is hinged to the hinge tube body 413. The locking part can pass through the locking through groove 422 and cooperate with the locking block 412. One end of the locking through groove 422 extends to one end of the locking plate body 421 to form a slotted structure, so that the locking part can rotate into the locking through groove 422.

[0037] In another embodiment, one end of the protective housing 300 along its width direction is hinged to the base 100. This connection can be achieved via a hinge. Rotating the protective housing 300 allows the clamping mechanism to be covered or opened. The end of the protective housing 300 opposite the hinged end can be locked to the base 100 via a locking assembly. The first locking member 410 further includes two hinge tubes 413, each extending along the length of the base 100 and fixed to it. The two hinge tubes 413 are spaced apart. The locking pin 411 has a T-shaped structure, with the horizontal part being the hinge portion and the vertical part being the locking portion. Both ends of the hinge portion are inserted into the hinge tubes 413 to achieve hinged connection between the hinge pin and the base 100, allowing the hinge pin to... It can rotate relative to the base 100. In addition, the locking through groove 422 on the locking plate 421 is a rectangular groove structure. The locking through groove 422 extends along the width direction of the protective shell 300, and one end of the locking through groove 422 extends to one end of the locking plate 421 to form a slotted structure. When the protective shell 300 is installed with the base 100, the locking pin 411 can be rotated from a horizontal state to a vertical state. During the rotation, the locking part enters the locking through groove 422 through the slotted part of the locking through groove 422, and then locks the protective shell 300 by connecting the locking block 412. When unlocking, the locking block 412 is moved on the locking part, so that the locking block 412 is separated from the locking plate 421. Then the locking part is rotated in the opposite direction, so that the locking part is disengaged from the locking through groove 422, thereby unlocking. The structure is simple. By rotating the locking part, the protective shell 300 and the base 100 can be locked and unlocked, making the operation simple.

[0038] In the specific structure of the cable sleeve 200, the end of the fixing part 210 away from the guide part 220 is provided with a first annular stop 211. The first annular stop 211 is arranged circumferentially around the fixing part 210. The protective housing 300 is provided with a second relief groove 330 at one end relative to the first relief groove 320. The second relief groove 330 communicates with the receiving cavity 310. One end of the fixing part 210 relative to the guide part 220 can extend out of the protective housing 300 through the second relief groove 330, and the diameter of the first annular stop 211 is larger than the diameter of the second relief groove 330. The guide part 220 includes a first half-tube 221 and a second half-tube 222. One end of the first half-tube 221 is fixedly connected to the fixing part 210, and the second half-tube 222 can be connected with the first half-tube 221 to form the guide part 220. The guide part 220 has an arc-shaped structure.

[0039] In this embodiment, as Figure 1 , Figure 3As shown, the cable sleeve 200 has a tubular structure, wherein the fixing part 210 has a straight tubular structure, and a first annular stop 211 is provided at one end of the fixing part 210 relative to the guide part 220. The first annular stop 211 has an annular plate structure and is coaxially arranged with the fixing part 210. Correspondingly, a second clearance groove 330 is provided at one end of the protective housing 300 relative to the first clearance groove 320. The second clearance groove 330 has a rectangular groove structure and extends vertically. The bottom end of the second clearance groove 330 extends to the bottom end of the protective housing 300 to form a slotted structure. The diameter of the first annular stop 211 is larger than the diameter of the second clearance groove 330. When the protective housing 300 is connected to the base 100, one end of the fixing part 210 can extend out of the protective housing 300 through the second clearance groove 330, and the first annular stop 211 can provide a positioning function for the protective housing 300. Furthermore, the guide section 220 includes a first half-tube 221 and a second half-tube 222, both of which are arc-shaped sheet structures. The first and second half-tubes 221 are connected to enclose and clamp the cable. Specifically, one end of the first half-tube 221 is fixed to one end of the fixing part 210. After the cable passes through the fixing part 210, it enters the interior of the first half-tube 221. Then, the second half-tube 222 is connected to the first half-tube 221 to clamp and guide the cable. The arc-shaped structure of the guide section 220 further enhances guidance and facilitates cable turning. In this structure, the guide section 220 is a split structure, facilitating cable clamping, and its arc shape facilitates cable turning and guidance.

[0040] In addition, an insulating pad is placed between the cable sleeve 200 and the cable to further protect the cable and prevent wear between the cable and the inner wall of the cable sleeve 200 when the cable rotates.

[0041] In addition, the first half-tube 221 is provided with first skirt protrusions 223 on both opposite sides along its radial direction, and the second half-tube 222 is provided with second skirt protrusions 224 on both opposite sides along its radial direction. When the first half-tube 221 and the second half-tube 222 are connected, the first skirt protrusions 223 and the second skirt protrusions 224 are connected to each other, and the radial dimensions of the first skirt protrusions 223 and the second skirt protrusions 224 are both larger than the diameter of the first clearance groove 320.

[0042] In this embodiment, as Figure 3As shown, the first half-tube 221 has first skirt protrusions 223 on both radial sides, which extend along the extension direction of the first half-tube 221. Correspondingly, the second half-tube 222 has second skirt protrusions 224 on both radial sides. When the first half-tube 221 and the second half-tube 222 are combined, the first skirt protrusions 223 and the second skirt protrusions 224 fit together. After the first skirt protrusions 223 and the second skirt protrusions 224 are combined, their diameter is larger than the diameter of the first clearance groove 320, thereby allowing the protective shell 300 to be installed between the first skirt protrusion and the first annular stop 211, thus providing positioning and preventing the protective shell 300 from moving. During connection, the first skirt protrusions 223 and the second skirt protrusions 224 can be connected by a bolt structure to improve the connection strength and connection stability.

[0043] In the specific structure of the clamping mechanism, the clamping mechanism includes a clamping base 500, which includes a first clamping member 510 and a second clamping member 520. The first clamping member 510 is fixedly connected to the base 100. The first clamping member 510 is provided with a first clamping half groove 511, and the second clamping member 520 is provided with a second clamping half groove 521. The first clamping member 510 and the second clamping member 520 are connected in cooperation so that the first clamping half groove 511 and the second clamping half groove 521 form a clamping groove for clamping the fixing part 210, and the fixing part 210 can rotate within the clamping groove. The fixing part 210 is provided with a second annular block 212 and a third annular block 213 in sequence along the first axis direction. The second annular block 212 and the third annular block 213 are both arranged along the circumference of the fixing part 210, and the clamping seat 500 is stuck between the second annular block 212 and the third annular block 213. The diameter of the second annular block 212 and the third annular block 213 is larger than the diameter of the clamping groove.

[0044] In this embodiment, as Figure 4As shown, the clamping base 500 extends along the width direction on the base 100. The clamping base 500 includes a first clamping member 510 and a second clamping member 520. Both the first clamping member 510 and the second clamping member 520 are rectangular block structures. The top end of the first clamping member 510 is provided with a first clamping half-groove 511, and the bottom end of the second clamping member 520 is provided with a second clamping half-groove 521. The bottom end of the first clamping member 510 is fixedly connected to the base 100, and the second clamping member 520 can cooperate with the first clamping member 510 so that the first clamping half-groove 511 and the second clamping half-groove 521 cooperate to form a clamping groove to accommodate the clamping fixing part 210. In addition, along the axial direction of the fixing part 210, the clamping base 500 is arranged in a series of... The device is provided with a second annular block and a third annular block, both of which are annular sheet structures. When the fixing part 210 is connected to the clamping mechanism, the fixing part 210 is first placed in the first clamping half groove 511, and then the second clamping member 520 is connected to the first clamping member 510, so that the second clamping half groove 521 clamps the other part of the fixing part 210. The first clamping member 510 and the second clamping member 520 are locked between the second annular stop 212 and the third annular stop 213. The diameters of the second annular stop 212 and the third annular stop 213 are both larger than the diameter of the clamping groove, so that the fixing part 210 and the clamping mechanism provide a positioning function, effectively preventing the fixing part 210 from moving.

[0045] In addition, the base 100 is provided with at least two clamping seats 500 along the direction of the first axis. In this embodiment, the base 100 is provided with two clamping seats 500 along its length direction, thereby improving the clamping stability of the cable sleeve 200.

[0046] In the connection structure of the first clamping member 510 and the second clamping member 520, the first clamping member 510 is provided with mounting grooves 512 at opposite ends, and the mounting grooves 512 are provided with first slots. The second clamping member 520 is provided with mounting blocks 522 at opposite ends, and the mounting blocks 522 are provided with second slots. The mounting blocks 522 are engaged with the mounting grooves 512. When the first clamping member 510 and the second clamping member 520 are engaged and connected, the first slots and the second slots are connected and engaged through the connecting pin 530.

[0047] In this embodiment, as Figure 4As shown, the first clamping member 510 has mounting grooves 512 at both ends along its length, and a through first slot is provided in the mounting groove 512 along its thickness. Correspondingly, the second clamping member 520 has mounting blocks 522 at both ends along its length that mate with the mounting grooves 512, and a through second slot is provided in the mounting block 522 along its thickness. During installation, the mounting blocks 522 of the second clamping member 520 are inserted into the mounting grooves 512 of the first clamping member 510, with the first slot and the second slot connected. Then, the connecting pin 530 passes through the first slot and the second slot in sequence to connect and fix the first clamping member 510 and the second clamping member 520. This structure facilitates connection and provides high connection stability.

[0048] More specifically, such as Figure 4 As shown, multiple balls 540 are movably arranged on the inner walls of both the first and second clamping semi-grooves, and these balls 540 are in movable engagement with the outer surface of the fixing part 210. To reduce frictional force during rotation of the fixing part 210 relative to the clamping mechanism, multiple balls 540 are evenly arranged on the inner walls of the first and second clamping semi-grooves. These balls 540 are rotatable, and when the clamping mechanism clamps the fixing part 210, the balls 540 contact the outer surface of the fixing part 210. When the fixing part 210 rotates, the balls 540 also rotate accordingly, thereby reducing friction with the fixing part 210 and improving the smoothness of rotation.
