Description

Technical Field

[0001] This utility model relates to the field of marine electrical design technology, specifically to a seismic-resistant support for cable trays. Background Technology

[0002] Marine electrical design is a core part of marine engineering, involving multiple aspects such as power system planning, equipment selection, safety protection and intelligent application. During the design process, some wires are fixed to the ship's ceiling through cable trays. Since ships usually vibrate during operation, anti-vibration supports are used to fix the cable trays.

[0003] The electrical design cable tray seismic support described in publication CN217215783U, by setting up a mounting base, buffer column, support spring, and limiting plate, can utilize the support spring to buffer vertical vibrations received by the mounting base, thereby improving the seismic resistance of the overall support structure. The addition of an adjusting sleeve and adjusting bolt facilitates height adjustment of the adjusting sleeve, making the support suitable for different installation environments. However, the existing technology still has shortcomings:

[0004] 1. Since the installation height of cable trays usually requires the entire device to be installed on the ceiling and then adjusted according to the specific wire length and aesthetics, the existing technology requires manual adjustment of the installation height of the cable trays through adjusting bolts and adjusting grooves, which is inconvenient to operate and reduces work efficiency.

[0005] 2. Due to the large number of devices on board, the number, type and routing of the connecting wires for different devices vary. Therefore, multiple cable trays are usually needed to facilitate the management of the wires. Existing technology requires repeated installation of multiple sets of mounting brackets, which is time-consuming and labor-intensive, and occupies a lot of space on the ship's ceiling, making it impractical.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The technical problem to be solved by this utility model is to address the above-mentioned issues and provide a seismic-resistant support for cable trays.

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a seismic-resistant support for cable trays, comprising:

[0009] The support rod is slidably connected to several sliding sleeves on its exterior;

[0010] The support rod has several evenly spaced threaded holes on its front side;

[0011] Bolt 1, which passes through both ends of the front part of the sliding sleeve and is threadedly connected to the threaded hole;

[0012] A lifting mechanism is provided at both ends of the upper part of a support rod, including a lead screw, a threaded tube, a guide rod, a sleeve, a limiting block, a synchronous pulley, a synchronous belt, a fixing frame, and a handle. The lead screw is rotatably connected to the front sides of both ends of the upper part of the support rod. The threaded tube is threadedly connected to the upper part of the lead screw. The guide rod is fixedly connected to the rear sides of both ends of the upper part of the support rod. The sleeve is slidably fitted onto the upper part of the guide rod. The limiting block is fixedly connected to the upper end of the guide rod and is adapted to the inside of the sleeve. The lower end of the lead screw passes through the support rod and is fixedly connected to the synchronous pulley. The synchronous belt is sleeved between the synchronous pulleys. The fixing frame is fixedly connected to the front side of one end of the lower part of the support rod. The lower part of the fixing frame extends to the lower side of the synchronous pulley. The handle is rotatably connected to the lower side of the fixing frame and passes through the fixing frame and is fixedly connected to the synchronous pulley.

[0013] Mounting plate, the mounting plate being disposed on the upper part of the sliding sleeve;

[0014] A cable trough, wherein the cable trough is disposed on the upper part of the mounting plate;

[0015] A fixing mechanism is provided between the mounting plate and the cable tray.

[0016] As an improvement, the fixing mechanism includes:

[0017] A clamping plate is disposed in the middle of the upper part of the wire groove;

[0018] The screw is fixedly connected to the middle of the upper two sides of the mounting plate, and the screw is threaded to both ends of the clamping plate;

[0019] Nuts are disposed at both ends of the upper part of the clamping plate and are threadedly connected to the screw.

[0020] As an improvement, connecting plates are provided between the two sides of the cable tray and the mounting plate, and the connecting plates are threadedly connected to the front and rear ends of the cable tray and the front and rear ends of the mounting plate with two bolts respectively.

[0021] As an improvement, damping rods are fixedly connected between the four lower corners of the mounting plate and the sliding sleeve, and shock-absorbing springs are sleeved on the outside of the damping rods.

[0022] As an improvement, a fixing plate is fixedly connected between the threaded tube and the upper end of the sleeve.

[0023] The advantages of this utility model compared with the prior art are as follows: 1. This utility model has multiple sliding sleeves on a support rod. The sliding sleeves are fitted with wire channels through a mounting plate and fixing mechanism. Each wire channel can classify and organize the wires according to the type and direction of the wires connected to different equipment, thereby reducing the overall number of equipment to be installed, saving time and effort, and reducing the space occupied on the ceiling. The sliding sleeves can slide left and right along the support rod to adjust the distance between the wire channels. The wire channels can be fixed by bolts and threaded holes. The shock-absorbing springs and damping rods play a shock-absorbing and buffering role for the wire channels, thereby better protecting the ship's circuitry.

[0024] 2. This utility model features a lifting mechanism that drives a synchronous wheel to rotate by turning a handle. The synchronous wheel, in conjunction with a synchronous belt, controls the synchronous rotation of two lead screws. The lead screws, in conjunction with a threaded tube, guide rod, sleeve, and limit block, can control the up-and-down movement of the support rod. Thus, the entire device can be fixed to the ceiling inside the ship using a fixing plate. Workers only need to turn the handle to adjust the installation height of the cable tray according to the actual wire length and aesthetics, making operation more convenient and greatly improving work efficiency.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Combined with appendix Figure 1-5 This utility model is provided with a support rod 1, and a number of sliding sleeves 2 are slidably connected to the outside of the support rod 1. The length of the support rod 1 and the number of sliding sleeves 2 are set according to the type, quantity and direction of the wires connected to the ship equipment. The sliding sleeves 2 can slide left and right along the support rod 1 to adjust the distance between different lines. A number of evenly distributed threaded holes 3 are opened on the front side of the support rod 1. Bolts 4 are passed through the front two ends of the sliding sleeves 2 and are threadedly connected to the threaded holes 3 for fixing the sliding sleeves 2.

[0033] The upper two ends of the support rod 1 are equipped with lifting mechanisms 5, including a lead screw 501, a threaded tube 502, a guide rod 503, a sleeve 504, a limit block 505, a synchronous pulley 506, a synchronous belt 507, a fixing frame 508, and a handle 509. The lead screw 501 is rotatably connected to the front side of the upper two ends of the support rod 1, and the threaded tube 502 is threadedly connected to the upper part of the lead screw 501. The guide rod 503 is fixedly connected to the rear side of the upper two ends of the support rod 1. The length of the guide rod 503 is the same as the length of the lead screw 501, and the upper part of the guide rod 503 is slidably sleeved. There is a sleeve 504, the length of which is the same as that of the threaded pipe 502. The upper end of the guide rod 503 is fixedly connected to a limiting block 505. The limiting block 505 is adapted to the inside of the sleeve 504. The limiting block 505, together with the bottom of the sleeve 504, plays a limiting role for the guide rod 503, preventing the guide rod 503 from falling off during the lifting and lowering process of the screw 501. A fixing plate 11 is fixedly connected between the upper end of the threaded pipe 502 and the sleeve 504. The fixing plate 11 has mounting holes at its four corners for fixing to the ceiling inside the ship.

[0034] The lower end of the lead screw 501 passes through the support rod 1 and is fixedly connected to the synchronous pulley 506. A synchronous belt 507 is sleeved between the synchronous pulleys 506. An L-shaped fixing bracket 508 is fixedly connected to the front side of the lower end of the support rod 1, and the lower part of the fixing bracket 508 extends to the lower side of the synchronous pulley 506. A handle 509 is rotatably connected to the lower side of the fixing bracket 508, and the handle 509 passes through the fixing bracket 508 and is fixedly connected to the synchronous pulley 506. A self-locking structure with a pin structure (not shown in the figure) is provided between the handle 509 and the fixing bracket 508 to limit the handle 509 and prevent the synchronous pulley 506 from rotating arbitrarily. By rotating the handle 509, the synchronous pulley 506 is driven to rotate, which, together with the synchronous belt 507, controls the synchronous rotation of the two lead screws 501. The lead screws 501, together with the threaded tube 502, drive the support rod 1 to move up and down, thereby adjusting the installation height of the wire trough 7.

[0035] A mounting plate 6 is provided on the upper part of the sliding sleeve 2. A wire groove 7 is provided on the upper part of the mounting plate 6 for organizing and storing wires. A fixing mechanism 8 is provided between the mounting plate 6 and the wire groove 7, including a clamping plate 801, a screw 802, a nut 803, a connecting plate 804, and a bolt 805. The clamping plate 801 is provided in the middle of the upper part of the wire groove 7. The screw 802 is fixedly connected to the middle of both sides of the upper part of the mounting plate 6, and the screw 802 passes through the clamping plate 801 and is threaded to both ends of the clamping plate 801. The upper ends of the clamping plate 801 are provided with... Nut 803 is threaded onto the outside of screw 802. By rotating nut 802, nut 802 can be controlled to move up and down along screw 802, thereby lowering nut 803 in the installation groove 7. Control clamping plate 801 clamps the groove 7 to fix it. L-shaped connecting plates 804 are provided between the two sides of the groove 7 and the mounting plate 6. Bolts 805 are threadedly connected between the connecting plates 804 and the front and rear ends of the groove 7 and the front and rear ends of the mounting plate 6, respectively, to further fix the groove 7 and keep it stable.

[0036] Damping rods 9 are fixedly connected between the four lower corners of the mounting plate 6 and the sliding sleeve 2. Shock-absorbing springs 10 are sleeved on the outside of the damping rods 9, which play a role in shock absorption and buffering between the mounting plate 6 and the cable tray 7, so as to prevent the ship from shaking during navigation, which would cause the internal wiring of the cable tray 7 to be unstable and affect the normal power supply.

[0037] In specific implementation of this utility model, such as Figure 1 As shown, during ship design, the equipment is installed and fixed to the ceiling inside the ship via the fixing plate 11 as needed. The distance between each sliding sleeve 2 is adjusted as needed, and then the sliding sleeve 2 is fixed by screwing the bolt 4 into the threaded hole 3. The wire trough 7 is placed on the upper part of the mounting plate 6, and the wire trough 7 is fixedly connected to the mounting plate 6 by the connecting plate 804 and the bolt 805. The clamping plate 801 is placed on the upper part of the wire trough 7 through the screw 802, and the nut 803 is screwed in from the upper part of the screw 802. The nut 803 is continuously rotated to make the nut descend and control the clamping plate 801 to clamp and fix the wire trough 7 for a second time. The wires connecting different equipment are sorted and passed through different wire troughs 7. According to the length of the wires and aesthetics, the handle 509 is rotated, and the support rod 1 is moved up and down by the lifting mechanism 5 to adjust the installation height of the wire trough 7, thus completing the installation of the wire trough 7.
