Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a quick-release cable tray structure for elevator wiring. Background Technology

[0002] Elevator wiring cable trays are an important component of elevator electrical systems, used to protect and organize various control cables, signal lines, and power lines within the elevator shaft. Made of flame-retardant materials, the trays possess excellent insulation properties and mechanical strength, effectively preventing cables from getting damp, worn, and subjected to external interference. They are an indispensable key component in elevator engineering.

[0003] In existing technologies, the connection between the cable tray and the mounting bracket relies on bolts for fastening. During installation, each screw must be tightened individually. This process is not only extremely time-consuming but also highly dependent on specialized tools. Tools like wrenches are simply not flexible enough to work in the narrow elevator shaft, causing great inconvenience to the construction. At the same time, existing cable trays lack effective partitioning structures, and various cables such as power cables and signal cables are mixed together haphazardly, which easily leads to tangling and seriously affects the stability of cable transmission. Moreover, when cable maintenance is required, it is difficult to quickly locate the cables due to the messy tangling. Utility Model Content

The clamping block is used to clamp the cable. A protective plate is detachably connected to the cavity. The surface of the protective plate has a slot adapted to the support column, and the support column moves within the slot.

[0008] Based on the preferred embodiment of this technical solution, the locking component includes a support plate for fixing the outer wall of the cable tray box, a support shaft on the rotating support plate, a clamping plate fixedly connected to the outer wall of the support shaft, a pressing plate fixed to one end of the clamping plate, a spring disposed between the cable tray box and the clamping plate, and a clamping wheel fixedly connected to the outer wall of the rotating shaft.

[0017] Please see Figure 1A further embodiment of this solution is as follows: The connecting mechanism includes a base 6 mounted on the mounting frame 1, a folded plate 7 fixedly connected to the outer wall of the slot box 2, a screw 8 threadedly connected to the folded plate 7, a knob 9 fixedly connected to one end of the screw 8, and a base 10 rotatably connected to the other end of the screw 8. The connecting surfaces of the base 6 and the base 10 are provided with interlocking limiting teeth 11. The base 6 (made of carbon steel) is fixed to the mounting frame 1 by welding, and its connecting surface is provided with serrated limiting teeth 11. The base 10 (made of aluminum alloy) is rotatably connected by bearings. At the end of the screw 8, the connecting surface is provided with reverse sawtooth-shaped limiting teeth 11. When the screw 8 rotates and the base 2 10 approaches the base 1 6, the two rows of limiting teeth 11 mesh with each other to form a mechanical interlocking structure, which can withstand horizontal shearing force and vertical pulling force. The folded plate 7 (made of stainless steel) is fixed to the outer wall of the wire trough box 2 by welding. The vertical section of the plate has a threaded hole. The screw 8 is engaged with the threaded hole. The knob 1 9 (knurled surface) is fixed to one end of the screw 8. When the knob 1 9 is rotated, the screw 8 drives the base 2 10 to move axially, so as to realize the quick positioning and locking of the wire trough box 2 and the mounting bracket 1.

[0018] Please see Figures 2-3 A further solution based on this embodiment is as follows: the fixing assembly includes a rotating shaft 12 rotatably connected in the cavity 5, a knob 13 fixedly connected to one end of the rotating shaft 12, a bidirectional threaded section formed on the outer wall of the rotating shaft 12, a drive block 14 threadedly connected to the rotating shaft 12, a support column 15 fixedly connected to the surface of the drive plate, and a clamping block 16 fixedly connected to the support column 15. The clamping block 16 is used to clamp the cable. A protective plate 17 is detachably connected to the cavity 5. The surface of the protective plate 17 has a groove 18 adapted to the column. The support column 15 moves within the groove 18. The rotating shaft 12 is connected via a deep groove ball bearing. The rotating shaft 12 is rotatably connected to the inner wall of the cavity 5. The outer wall of the rotating shaft 12 is provided with a bidirectional thread section (three sections each of left-hand and right-hand). The drive block 14 is connected to the bidirectional thread section through a threaded hole. The knob 13 is fixed to one end of the rotating shaft 12. When the knob 13 is rotated, the rotating shaft 12 drives the two drive blocks 14 to move in opposite directions. The surface of the drive block 14 is welded with a support column 15 (made of stainless steel). The support column 15 is fixed with a clamping block 16 (made of silicone rubber). The clamping block 16 is provided with a V-groove and the surface is covered with anti-slip texture. When the drive block 14 moves, the clamping block 16 clamps the cable. The protective plate 17 is fixed to the cavity 5 by a buckle.

[0019] Please see Figure 4A further solution based on this embodiment is as follows: The locking assembly includes a support plate 19 fixedly connecting the outer wall of the cable tray 2, a support shaft 20 rotatably connecting the support plate 19, a clamping plate 21 fixedly connected to the outer wall of the support shaft 20, a pressing plate 22 fixed to one end of the clamping plate 21, a spring 23 disposed between the cable tray 2 and the clamping plate 21, and a locking wheel 24 fixedly connected to the outer wall of the rotating shaft 12. The locking wheel 24 is provided with locking teeth, the clamping plate 21 is clamped on the locking teeth, and the locking wheel 24 is fixed to the rotating shaft 12 by a flat key. Its outer circumference is provided with The device has 12 locking teeth. The locking plate 21 (made of aluminum alloy) is rotatably connected to the support plate 19 via the support shaft 20 (made of stainless steel). The spring 23 is connected between the locking plate 21 and the wire groove box 2, providing pre-tightening force so that the locking plate 21 always engages with the locking teeth. When the press plate 22 is pressed, the locking plate 21 rotates around the support shaft 20 and disengages from the locking teeth. The rotating shaft 12 can rotate freely. After the press plate 22 is released, the spring 23 pushes the locking plate 21 to reset, and the locking hook re-engages with the locking teeth. The locking teeth are chamfered to facilitate the smooth insertion of the locking hook.

[0020] Please see Figure 5 A further solution based on this embodiment is as follows: one end of the partition 4 is integrally fixedly connected to a convex rail 25, and the cover 3 is provided with a sliding groove 26 that is adapted to the convex rail 25. The convex rail 25 and the sliding groove 26 are slidably connected. The surface of the convex rail 25 is polished. The sliding groove 26 and the convex rail 25 form a clearance fit (gap 0.1-0.2mm). When the cover 3 slides, the convex rail 25 and the sliding groove 26 constrain the cover 3 to retain only the horizontal degree of freedom, preventing it from tilting.

[0021] Please see Figure 5 A further solution based on this embodiment is as follows: a magnet is embedded in the contact surface of the convex rail 25 and the slide groove 26, the convex rail 25 and the slide groove 26 are magnetically connected, and a neodymium iron boron magnet is embedded in the contact surface of the convex rail 25 and the slide groove 26 to ensure that the box cover 3 is subjected to magnetic force throughout the process. When the box cover 3 slides to the closed position, the magnetic attraction will automatically seal the box cover 3 and the wire groove box 2.

[0022] Please see Figure 5 A further solution based on this embodiment is as follows: an extension block 27 is integrally fixedly connected to the upper edge of the cable tray box 2, and a U-shaped block 28 is integrally fixedly connected to the edge of the box cover 3. The extension block 27 and the U-shaped block 28 are slidably connected. The extension block 27 is inserted into the groove of the U-shaped block 28 to form an anti-detachment structure and withstand vertical pulling force. The groove of the U-shaped block 28 is chamfered to facilitate the sliding of the extension block 27. The first level of anti-detachment relies on the mechanical cooperation between the extension block 27 and the U-shaped block 28, and the second level of anti-detachment relies on the magnetic connection between the convex rail 25 and the sliding groove 26. The two-level anti-detachment structure reduces the probability of the box cover 3 being accidentally opened.

[0023] Working principle: When carrying out elevator wiring work, the cable tray box 2 is installed. The cable tray box 2 is made of flame-retardant alloy material and is integrally formed into 3 independent chambers by the partition 4. The surface of the partition 4 is provided with reinforcing ribs to improve the compressive strength of the chambers. Each chamber is marked with different colors of red, yellow and blue to facilitate subsequent cable classification and management. Rotating the knob 9 causes the screw 8 to drive the base 10 to move axially. When the base 10 is close to the base 6, the two rows of limiting teeth 11 mesh with each other to form a mechanical interlocking structure, which can withstand horizontal shear force and vertical pull force, so as to realize the quick positioning and locking of the cable tray box 2 and the mounting bracket 1. After the cable tray box 2 is installed, open the cover 3. Since the surface of the convex rail 25, which is integrally fixed to one end of the partition 4, is polished, it forms a clearance fit (0.1-0.2mm) with the matching slide groove 26 opened on the cover 3. The contact surface of the convex rail 25 and the slide groove 26 is embedded with neodymium iron boron magnets for magnetic connection. At the same time, the extension block 27, which is integrally fixed to the upper edge of the cable tray box 2, and the U-shaped block 28, which is integrally fixed to the edge of the cover 3, are slidably connected to form a two-stage anti-detachment structure. This structure not only restricts the cover 3 to retain only horizontal freedom to prevent tilting, but also ensures that the cover 3 is subjected to magnetic force throughout the process. When it slides to the closed position, it can automatically close, and the probability of accidental opening is reduced. After opening the cover 3, put the different cables into the independent chamber of the cable tray box 2 according to the color label. Next, adjust the fixing assembly. In the fixing assembly, the rotating shaft 12 is rotatably connected to the inner wall of the two recesses 5 at the bottom of the cable tray box 2 via a deep groove ball bearing. Its outer wall is provided with a bidirectional threaded section with three sections each of left-hand and right-hand rotation. The drive block 14, made of stainless steel, is connected to the bidirectional threaded section through a threaded hole. The surface of the drive block 14 is welded with a support column 15. The support column 15 is fixed with a clamping block 16 made of silicone rubber and provided with a V-groove and anti-slip texture. A knob 13 made of stainless steel is rotatably fixed at one end of the rotating shaft 12. The rotating shaft 12 drives the two drive blocks 14 to move in opposite directions, causing the clamping block 16 to clamp the cable. A detachable protective plate 17 is fixed on the recess 5 by a snap fastener. The surface of the protective plate 17 has a slot 18 that matches the support column 15. The support column 15 moves in the slot 18, which plays a protective role for the fixing assembly. After the cable is secured, operate the locking assembly. The locking assembly includes a support shaft 20 fixedly connected to the support plate 19 on the outer wall of the cable tray 2, and a rotatable clamping plate 21 made of aluminum alloy. One end of the clamping plate 21 is fixed to a pressing plate 22. A spring 23 is provided between the cable tray 2 and the clamping plate 21 to provide preload, ensuring that the clamping plate 21 is always engaged and fixed to the outer wall of the rotating shaft 12 by a key and a locking wheel 24 with 12 teeth on its outer circumference. Pressing the pressing plate 22 causes the clamping plate 21 to rotate around the support shaft 20 and disengage from the teeth, allowing the rotating shaft 12 to rotate freely. After releasing the pressing plate 22, the spring 23 pushes the clamping plate 21 back to re-engage with the teeth, thus locking and unlocking the fixing assembly and ensuring the cable is securely fixed. Finally, close the cover 3 to complete the elevator cable wiring work. During regular inspections and maintenance, press the locking assembly button 22 to disengage the locking plate 21 from the locking teeth, rotate the knob 13 to release the cable clamp 16, and then rotate the knob 9 to separate the base 10 from the base 6. This allows for quick disassembly of the cable tray 2 and inspection and maintenance of the cable. Through quick-release connection and multi-cavity separation, efficient and safe wiring of elevator cables can be achieved.
