Description

Technical Field

[0001] This utility model relates to the technical field of cable trays, specifically a suspended cable tray installation suspension structure. Background Technology

[0002] Suspended cable trays suspend cable trays from ceilings, walls, or other supporting structures. The suspension structure distributes the weight of the cable trays, preventing deformation or collapse due to gravity. Primarily used for supporting and managing cables, suspended structures can flexibly adapt to different floor heights and spans in situations with limited interior space, avoiding the occupation of excessive floor space.

[0003] Existing cable tray installation suspension structures typically employ ladder or tray structures, offering better airflow and aiding in cable heat dissipation. Compared to ground-laying, suspension structures reduce heat buildup and extend cable lifespan. However, with tray-type suspension structures, changes to the cable tray support height require adjusting the height of the telescopic support beams. This typically involves bolts fixing the support beam length, necessitating multiple bolt removals and re-adjustments for each subsequent adjustment. This cumbersome installation process reduces installation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a suspended cable tray installation suspension structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A suspended cable tray installation suspension structure includes a crossbeam, with support beams arranged at both ends of the crossbeam in a vertical direction, and a support column connected to the end of the support beam away from the crossbeam to support the cable tray.

[0007] A threaded pusher, installed on the support beam, is used to change the length of the support beam;

[0008] The symmetrically arranged telescopic reinforcing members are hinged at one end to the crossbeam and at the other end to the supporting column. When the length of the supporting beam changes, the length of the telescopic reinforcing members also changes accordingly.

[0009] The suspended cable tray installation suspension structure as described above: the support beam includes a first lifting column and a second lifting column, one end of the first lifting column is fixed to the crossbeam, and the other end is slidably connected to the second lifting column, and the end of the second lifting column extending out of the first lifting column is fixed to the receiving column.

[0010] The suspended cable tray installation suspension structure as described above: the threaded pusher includes a screw rod rotatably installed in the first lifting column, one end of the screw rod passes through the crossbeam and is driven to rotate by a drive member provided in the crossbeam, and the other end extends into the second lifting column and is threadedly connected to the second lifting column.

[0011] The suspended cable tray installation suspension structure as described above: the driving component includes a drive shaft rotatably installed in the crossbeam, one end of the drive shaft is connected to a drive bolt, and the drive shaft is connected to the lead screw through two sets of bevel gears respectively.

[0012] The suspended cable tray installation suspension structure as described above: the telescopic reinforcement includes a first connecting plate and a second connecting plate that are slidably installed, one end of the first connecting plate is hinged to the crossbeam, and the end of the second connecting plate away from the first connecting plate is hinged to the support column.

[0013] It also includes a one-way locking element that connects the first connecting plate and the second connecting plate.

[0014] The suspended cable tray installation suspension structure as described above: the one-way locking element includes:

[0015] The first limiting block has multiple first locking teeth on one side and at least two guide shafts fixed on the other side. The guide shafts pass through the support plate fixed on the second connecting plate and are slidably connected to the support plate.

[0016] A spring is sleeved on the guide shaft and located between the support plate and the first limiting block, with both ends of the spring abutting against the support plate and the first limiting block, respectively.

[0017] The second limiting block is installed on the side of the second connecting plate facing the first connecting plate, and a second locking tooth is formed on the second limiting block to match the first locking tooth.

[0018] The suspended cable tray installation suspension structure described above: the first connecting plate has an embedded groove on the side facing the second connecting plate, and the second connecting plate is slidably embedded into the embedded groove;

[0019] At least two strip grooves are also formed on the side wall of the embedded groove, and a strip block that slides and adapts to the strip groove is fixedly provided on the second connecting plate.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] By driving the threaded pusher to work, the length of the support beam is changed, thereby adjusting the support height of the support column. At the same time as the length of the support beam changes, the end of the telescopic reinforcement that is hinged to the support column also begins to move. At this time, the length of the telescopic reinforcement changes synchronously. The crossbeam, the support beam, and the telescopic reinforcement together form a triangular structure. When the length of the support beam changes, the length and support angle of the telescopic reinforcement change, ensuring that the height of the cable tray can be quickly adjusted while the overall suspension structure remains stable.

[0030] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0031] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0032] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0033] Please see Figures 1-7 In this embodiment of the utility model, a suspended cable tray installation suspension structure includes a crossbeam 1, with support beams arranged at both ends of the crossbeam 1 in a vertical direction, and a support column 2 that can support the cable tray is connected to the end of the support beam away from the crossbeam 1.

[0034] A threaded pusher, installed on the support beam, is used to change the length of the support beam;

[0035] The symmetrically arranged telescopic reinforcing members are hinged at one end to the crossbeam 1 and at the other end to the supporting column 2. When the length of the supporting beam changes, the length of the telescopic reinforcing members changes accordingly.

[0036] In one embodiment, a fixing plate 3 is symmetrically arranged on the support column 2. The fixing plate 3 is fixed to the cable tray by bolts to achieve a stable connection between the support column 2 and the cable tray.

[0037] In this embodiment, by driving the threaded pusher to work, the length of the support beam is changed, and the support height of the support column 2 is adjusted. At the same time as the length of the support beam changes, the end of the telescopic reinforcement that is hinged to the support column 2 also begins to move. At this time, the length of the telescopic reinforcement changes synchronously. The crossbeam 1, the support beam, and the telescopic reinforcement together form a triangular structure. When the length of the support beam changes, the length and support angle of the telescopic reinforcement change, ensuring that the suspension structure remains stable when the height of the cable tray is adjusted.

[0038] For further solutions to this utility model, please refer to [link / reference]. Figure 2 and Figure 3 The supporting beam includes a first lifting column 8 and a second lifting column 9. One end of the first lifting column 8 is fixed to the crossbeam 1, and the other end is slidably connected to the second lifting column 9. One end of the second lifting column 9 extending out of the first lifting column 8 is fixed to the receiving column 2.

[0039] The threaded pusher includes a lead screw 7 rotatably installed in the first lifting column 8. One end of the lead screw 7 passes through the crossbeam 1 and is driven to rotate by a drive component disposed in the crossbeam 1. The other end extends into the second lifting column 9 and is threadedly connected to the second lifting column 9.

[0040] The driving component includes a drive shaft 4 rotatably mounted inside the crossbeam 1. One end of the drive shaft 4 is connected to a drive bolt 5, and the drive shaft 4 is connected to the lead screw 7 via two sets of bevel gears 6 respectively.

[0041] Preferably, at least two sliding grooves are formed on the inner wall of the first lifting column 8, and a slider 901 that is slidably adapted to the sliding grooves is fixedly provided on the outer wall of the second lifting column 9. Under the limiting effect of the sliding grooves and the slider 901, the first lifting column 8 and the second lifting column 9 are slidably connected.

[0042] Specifically, when adjusting the support height of the cable tray, a wrench is used to control the rotation of the drive bolt 5, so that the drive bolt 5 rotates synchronously and drives the drive shaft 4 to rotate synchronously. Under the transmission of the bevel gear set 6, the two sets of symmetrically arranged lead screws 7 can rotate synchronously to achieve synchronous adjustment of the length of the two sets of support beams. When the lead screw 7 rotates, under the restriction of the slide groove and the slider 901, it drives the second lifting column 9 to move linearly along the axis of the lead screw 7 to adjust the suspension height of the cable tray. During the height adjustment, the cable tray always remains balanced.

[0043] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The telescopic reinforcement includes a first connecting plate 10 and a second connecting plate 11 that are slidably installed. One end of the first connecting plate 10 is hinged to the crossbeam 1, and the end of the second connecting plate 11 away from the first connecting plate 10 is hinged to the support column 2.

[0044] It also includes a one-way locking element that connects the first connecting plate 10 and the second connecting plate 11.

[0045] When the supporting column 2 rises, it drives the second connecting plate 11 to move upward synchronously. At this time, the second connecting plate 11 is restricted by the first connecting plate 10 and can slide relative to the first connecting plate 10. The one-way locking device ensures that when the first connecting plate 10 and the second connecting plate 11 are shortened, it does not hinder the sliding of the second connecting plate 11 relative to the first connecting plate 10. At the same time, it can also restrict the reverse movement of the second connecting plate 11, thereby ensuring that the first connecting plate 10 and the second connecting plate 11 play a supporting role during the support process.

[0046] For further solutions to this utility model, please refer to [link / reference]. Figure 5 , Figure 6 and Figure 7 The one-way locking element includes:

[0047] The first limiting block 12 has a plurality of first locking teeth 1201 formed on one side and at least two guide shafts 15 fixed on the other side. The guide shafts 15 pass through the support plate 14 fixed on the second connecting plate 11 and are slidably connected to the support plate 14.

[0048] Spring 16 is sleeved on the guide shaft 15 and located between the support plate 14 and the first limiting block 12. The two ends of the spring 16 abut against the support plate 14 and the first limiting block 12, respectively.

[0049] The second limiting block 13 is installed on the side of the second connecting plate 11 facing the first connecting plate 10, and a second locking tooth 1301 adapted to the first locking tooth 1201 is formed on the second limiting block 13.

[0050] When the second lifting column 9 rises, the second connecting plate 11 moves relative to the first connecting plate 10 along the length direction of the first connecting plate 10 under the pull of the second lifting column 9. The second limiting block 13 on it moves synchronously. During the movement, the second locking tooth 1301 moves relative to the first locking tooth 1201. At this time, the second locking tooth 1301 exerts an inclined force on the first locking tooth 1201. When the first limiting block 12 moves along the axial direction of the guide shaft 15, it drives the guide shaft 15 to move synchronously. When the guide shaft 15 moves, it will further compress the spring 16, so that the spring 16 stores elastic potential energy. When the second connecting plate 11 stops moving, the second limiting block 13 stops compressing the first limiting block 12, the spring 16 releases elastic potential energy, and drives the first limiting block 12 to reset. At this time, the right-angle end on the first locking tooth 1201 abuts against the right-angle end on the second locking tooth 1301, thereby preventing the position of the second connecting plate 11 from shifting back.

[0051] In this embodiment, both the first locking tooth 1201 and the second locking tooth 1301 are arranged in a right-angled triangular structure, and the inclined surface of the first locking tooth 1201 abuts against the inclined surface of the second locking tooth 1301. When the second locking tooth 1301 moves relative to the first locking tooth 1201, the second locking tooth 1301 generates an inclined pressing force on the first locking tooth 1201. When the first locking tooth 1201 and the second locking tooth 1301 are fully engaged, the first locking tooth 1201 is at the highest point of its stroke. At this time, the near-right-angled triangle formed on the first locking tooth 1201... The triangular structure is placed between two adjacent second teeth 1301 to form an insertion slot. When the first tooth 1201 is subjected to an inclined squeezing force, the first tooth 1201 slides along the axial direction of the guide shaft 15. When the first tooth 1201 is at the lowest point of its stroke, the end of the triangular structure formed by the first tooth 1201 and the end of the triangular structure formed by the second tooth 1301 are on the same horizontal plane. Then the second limiting block 13 continues to move, the first tooth 1201 loses its abutment force, and is reset by the elastic action of the spring 16.

[0052] The first connecting plate 10 has an inset groove on the side facing the second connecting plate 11, and the second connecting plate 11 is slidably embedded in the inset groove;

[0053] At least two strip grooves 1001 are formed on the side wall of the embedded groove, and a strip block 1101 that is slidably adapted to the strip groove 1001 is fixedly provided on the second connecting plate 11.

[0054] When the second connecting plate 11 moves, the strip block 1101 on it moves synchronously, and under the constraint of the strip groove 1001, the first connecting plate 10 and the second connecting plate 11 are slidably connected.

[0055] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0056] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
