Description

Technical Field

[0001] This utility model relates to the field of cable tray layer fixing technology, and in particular to a cable tray layer fixing device that is easy to maintain. Background Technology

[0002] Cable trays are a critical infrastructure for laying large numbers of cables in modern buildings (such as data centers, factories, commercial complexes, and rail transit). To save space and plan routes rationally, multi-layer cable trays are usually arranged side by side or in layers, and the core component supporting these layered cable trays is the layer fixing device.

[0003] Currently, most devices achieve layered fixation by directly welding the crossbeams to the columns. While this ensures structural strength, it does not allow for adjustment of the layer spacing, and maintenance requires disassembling bolts point by point, which is time-consuming. Some devices use a slot structure for quick placement of the cable tray, but the lack of a locking mechanism between the slot and the locking block makes the cable tray prone to slippage in vibrating environments (such as generator rooms and substations), resulting in insufficient stability. Therefore, there is an urgent need to develop a layered fixing device that combines quick assembly and disassembly, flexible adjustment, and stable reliability.

[0004] Chinese patent document CN213937276U discloses a cable tray fixing device that is easy to assemble, including a first cable tray plate, a second cable tray plate, and a connecting block. A cover plate is provided at the upper end of the first cable tray plate. The lower end of a round rod is threadedly connected to the second cable tray plate. A spring is connected to the inner side of the movable plate, and a pressure-bearing component is provided inside the spring. A first mounting plate is connected to the lower ends of both the first and second cable tray plates. A mounting block is rotatably connected to the inner side of the movable plate, and a connecting block is connected to the outer side of the mounting block. A connecting rod is connected to the upper end of the connecting block, and a connecting plate is installed on the outer side of the connecting rod. A second mounting plate is slidably connected inside the connecting plate, and limit blocks are installed on the outer sides of both the second and first mounting plates. This cable tray fixing device, which is easy to assemble, provides good fixing effect for cable trays, does not affect the use of cable trays, and is convenient to assemble.

[0005] However, the device described in the aforementioned patent documents has the following drawbacks when implemented: the device does not have a layered adjustment structure, and it cannot flexibly adjust the distance between cable tray layers according to cable laying requirements, thus limiting its applicability; the worm gear device has a complex structure and its adjustment is used to fine-tune the spacing between mounting plates, but this function is rarely needed in actual maintenance, which instead increases complexity and failure rate. Utility Model Content

[0006] The main purpose of this utility model is to provide a cable tray layer fixing device that is easy to maintain and can effectively solve the problems mentioned above.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A cable tray layer fixing device for easy maintenance includes two support components. Several layer adjustment components are installed on the side of the two support components that are close to each other. Two slots are installed on the upper end of each of the several layer adjustment components. Cable tray components are installed on the upper end of each of the two slots. Elastic buckles are installed on the side of the two slots that are far apart from each other.

[0009] Preferably, the support assembly includes a base and a column, and two reinforcing ribs are installed between the base and the column.

[0010] Preferably, the layered adjustment component includes a crossbeam, and two limiting blocks are fixedly connected to the left and right sides of the crossbeam respectively.

[0011] Preferably, the cable tray assembly includes a housing, and two sets of several locking blocks are installed at the lower end of the housing.

[0012] Preferably, both slots are installed on the upper surface of the crossbeam along the length direction.

[0013] Preferably, the elastic buckle includes a fixing seat, which is installed on the outer wall of the slot. A metal rod is installed on one side of the fixing seat, and a spring is sleeved on the outer surface of the metal rod. A latch is installed on one side of the spring, and the latch is slidably connected to the metal rod. A disc is rotatably connected to one side of the metal rod passing through the latch. Two metal pillars are installed on the side of the latch and the disc that are close to each other. The two metal pillars are symmetrically distributed along the diameter of the disc. The side of the latch near the disc has two cylindrical holes and two arc-shaped grooves.

[0014] Preferably, the four card blocks closest to the column in the two groups of several card blocks are each provided with a groove, the height and width of which are greater than the height and width of the vertical axis of the card tongue.

[0015] Preferably, the diameter of the cylindrical hole is larger than the diameter of the metal column, and the diameter of the arc-shaped groove is the same as the diameter of the metal column.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This device, through its designed elastic buckle, slot, and block structure, enables flexible adjustment of the cable tray layer spacing to meet different laying and maintenance needs, while ensuring the stable support of the overall structure.

[0018] 2. This device, through the combination of the crossbeam and limit block of the layered adjustment component, the multiple sets of threaded connection holes on the side of the column, and the insertion and positioning structure of the slot and the cable tray block, can realize flexible stepless adjustment of the cable tray layer height and stable load bearing. Loosening the crossbeam bolts allows for up-and-down sliding adjustment of the height. After re-locking, the limit block further enhances the anti-displacement ability, completely replacing the traditional welding and other difficult-to-maintain fixing methods.

[0019] 3. The components of this device have simple structures, low manufacturing costs, and are easy to install and maintain. They are also low in complexity and failure rate, making them suitable for large-scale promotion and application. Attached Figure Description

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1, as Figure 1As shown, a cable tray layer fixing device that is easy to maintain includes two support components 1. Several layer adjustment components 2 are installed on the side of the two support components 1 that are close to each other. Two slots 4 are installed on the upper end of each of the several layer adjustment components 2. Cable tray components 3 are installed on the upper end of each of the two slots 4. Elastic buckles 5 are installed on the side of the two slots 4 that are far apart from each other.

[0029] Furthermore, such as Figure 2 As shown, the support assembly 1 includes a base 11 and a column 13, with two reinforcing ribs 12 installed between the base 11 and the column 13. The column 13 is made of high-strength square tubing, and its four sides have several sets of evenly distributed connecting holes along its length. These connecting holes are threaded holes, facilitating connection with other components. The base 11 has mounting holes, allowing the column 13 to be fixed to the ground or wall using expansion bolts, enhancing the overall stability of the device. The base 11, column 13, and reinforcing ribs 12 form a triangular relationship, further improving the firmness of the connection between the base 11 and column 13 and preventing the column 13 from tilting or swaying under load.

[0030] Furthermore, such as Figure 3 As shown, the layered adjustment component 2 includes a crossbeam 21, and two limiting blocks 22 are fixedly connected to the left and right sides of the crossbeam 21 respectively.

[0031] The crossbeam 21 is a rectangular steel tube with connecting lugs welded to both ends. Threaded holes are provided on the connecting lugs. Threaded holes are provided on the four crossbeams 21 on both sides of each crossbeam 21. After the crossbeam 21 is adjusted to a suitable height, the crossbeam 21 can be further fixed by screwing in the threaded holes of the limiting block 22 to prevent displacement of the crossbeam 21 during use.

[0032] Furthermore, both slots 4 are installed along the length of the upper surface of the crossbeam 21. The two slots 4 are parallel to each other and have a certain distance between them. Both slots 4 are also a certain distance from both ends of the crossbeam 21. This distance is greater than the overall length of the elastic buckle 5, ensuring that the installation position of the elastic buckle 5 will not obstruct the installation of the crossbeam 21.

[0033] Further reading Figure 4 The cable tray assembly 3 includes a housing 31, with two sets of several locking blocks 32 installed at the lower end of the housing 31. The two sets of several locking blocks 32 are welded to both sides of the bottom of the housing 31, corresponding one-to-one with the positions of the two slots 4. The center-to-center distance between the locking blocks 32 is the same as the center-to-center distance between the two slots 4. The locking blocks 32 are cuboid block structures, with a width slightly smaller than the opening width of the slots 4 for easy insertion.

[0034] During installation, the cable tray assembly 3 is placed directly above the layer adjustment assembly 2, and the locking block 32 will be locked into the slot 4 for fixation.

[0035] It should be noted that the connecting lugs on the crossbeam 21 are connected to the connecting holes on the column 13 by bolts. After the bolts pass through the adjustment holes and the connecting holes, they are tightened with nuts. By loosening the nuts, the crossbeam 21 can be moved up and down along the adjustment holes, thereby adjusting the height of the crossbeam 21 and realizing flexible adjustment of the spacing between the three layers of the cable tray assembly to meet different maintenance needs.

[0036] In summary, the core of this solution lies in achieving adjustable and rapid positioning of the cable tray's layer height. First, the base 11 of the support assembly 1 is fixed to the ground or wall using expansion bolts. Two reinforcing ribs 12 form a triangular support between the column 13 and the base 11, ensuring overall stability. The four sides of the column 13 have evenly distributed threaded connection holes for installing the layer adjustment assembly 2. Connecting lugs are welded to both ends of the crossbeam 21 of the layer adjustment assembly 2, connecting to the threaded holes in the column 13 via bolts. Limiting blocks 22 welded to both sides of the crossbeam 21 can be further screwed into limiting bolts to prevent displacement of the crossbeam 21.

[0037] Two slots 4 are installed parallel to each other along the length of the upper surface of the crossbeam 21, with their spacing matching the center distance of the two sets of locking blocks 32 at the bottom of the cable tray assembly 3. The outer shell 31 of the cable tray assembly 3 is directly inserted into the slots 4 through the locking blocks 32 at the bottom, completing the initial fixation. When adjusting the height, loosen the connecting bolts between the crossbeam 21 and the column 13, move the crossbeam 21 up and down along the threaded hole of the column 13 to the target position, and then tighten it again, realizing the flexible adjustment of the layer spacing of the cable tray assembly 3.

[0038] Example 2, based on Example 1, includes a device for restricting and fixing the placed cable tray assembly 3, such as... Figure 3 and Figure 5 As shown, the elastic buckle 5 includes a fixing seat 51, which is installed on the outer wall of the slot 4. A metal rod 52 is installed on one side of the fixing seat 51. A spring 53 is sleeved on the outer surface of the metal rod 52. The spring 53 is made of high-strength elastic steel. A latch 54 is installed on one side of the spring 53. The latch 54 is slidably connected to the metal rod 52. The metal rod 52 passes through the latch 54 and is rotatably connected to a disc 56. Two metal pillars 55 are installed on the side of the latch 54 and the disc 56 that are close to each other. A rubber ball is fixed to the front of each of the two metal pillars 55, which has good wear resistance and elasticity. The two metal pillars 55 are symmetrically distributed along the diameter of the disc 56. The side of the latch 54 that is close to the disc 56 has two cylindrical holes 57 and two arc-shaped grooves 58.

[0039] Furthermore, the diameter of the cylindrical hole 57 is larger than the diameter of the metal pillar 55, and the diameter of the arc-shaped groove 58 is the same as the diameter of the metal pillar 55. The purpose of this design is that when the latch 54 slides on the metal rod 52 under the elastic force of the spring 53, the two metal pillars 55 can pass through the two cylindrical holes 57 without obstructing the sliding path of the latch 54; in addition, when the disk 56 is rotated 90 degrees, the two metal pillars 55 move to the positions of the two arc-shaped grooves 58 respectively, and when the latch 54 slides, the two metal pillars 55 will insert into the two arc-shaped grooves 58, thereby blocking the sliding of the latch 54.

[0040] For further details, please refer to [link / reference]. Figure 6 In the two groups of several card blocks 32, the four card blocks 32 closest to the column 13 each have a groove on one side, the height and width of which are slightly greater than the height and width of the vertical part of the card tongue 54.

[0041] It should be noted that the latch 54 has an L-shaped structure and is made of a smooth material. Its horizontal part is connected to the metal rod 52 and the spring 53, and can slide on the outer surface of the metal rod 52. The front of its vertical part has a semi-circular structure, which makes it easy to insert into the groove of the latch block 32. After insertion, its front end just touches the inner wall of the groove.

[0042] Specifically, when the cable tray assembly 3 is placed into the slot 4, the locking block 32 moves downward into the groove of the slot 4, and its bottom contacts the front of the vertical part of the latch 54. Due to the continuous downward pressure, the latch 54 is squeezed to one side and moves, thus sliding on the metal rod 52. Due to the elastic force of the spring 53, when the locking block 32 is fully engaged in the slot 4, the front end of the latch 54 is also engaged in the groove of the locking block 32. At this time, after the disc 56 is rotated 90 degrees, the arc-shaped groove 58 blocks the latch 54 from sliding outward, and the groove of the locking block 32 blocks the inward movement of the latch 54, thus ensuring the left and right movement path of the cable tray assembly 3. In addition, since the slot 4 prevents the locking block 32 from moving back and forth, it ensures that the cable tray assembly 3 will not move back and forth due to external factors, such as wind. Through the limiting effect of the slot 4 and the limiting effect of the elastic buckle 5, the stability of the cable tray assembly 3 is ensured. Furthermore, when disassembly and maintenance are required, the cable tray assembly 3 can be removed by rotating the disc 56 90 degrees in the initial direction. This process enables the rapid disassembly and assembly of the cable tray assembly 3, allowing maintenance personnel to easily remove or install the cable tray assembly 3 from the fixing device, greatly shortening maintenance time and improving both stability and convenience of maintenance.

[0043] In summary, when implementing this solution, the fixing seat 51 of the elastic buckle 5 is pre-installed on the outer wall of the slot 4. One end of the metal rod 52 is connected to the fixing seat 51, and the other end passes through the latch 54 and is rotatably connected to the disc 56. One end of the spring 53 sleeved on the outer surface of the metal rod 52 abuts against the fixing seat 51, and the other end is connected to the latch 54. The two metal pillars 55 on the disc 56 are symmetrically distributed along their plumb diameter. The diameter of the cylindrical hole 57 on the latch 54 is larger than the diameter of the metal pillar 55, and the diameter of the arc groove 58 is the same as the diameter of the metal pillar 55. When the lower end of the outer shell 31 of the cable tray assembly 3 is inserted into the slot 4, the groove sides of the four locking blocks 32 near the column 13 will contact the vertical semi-circular structure of the latch 54. The continuous downward pressure pushes the latch 54 to slide away from the slot 4 along the metal rod 52, and the spring 53 is compressed. At this time, the metal column 55 passes through the cylindrical hole 57 without obstructing the sliding. When the locking block 32 is fully inserted into the slot 4, the elastic force of the spring 53 causes the latch 54 to return to its original position, and the front end of its vertical part is inserted into the groove of the locking block 32. The disc 56 rotates 90 degrees, and the metal column 55 enters the arc groove 58, restricting the sliding of the latch 54. Combined with the front and rear limit of the locking block 32 by the slot 4, the cable tray assembly 3 is stably fixed. During maintenance, rotate the disc 56 90 degrees in the opposite direction, and the metal post 55 returns to the position of the cylindrical hole 57. Press the latch 54 to compress the spring 53 so that it disengages from the groove of the latch block 32, and the cable tray assembly 3 can be removed from the slot 4 to complete the quick disassembly and assembly.
