Description

Technical Field

[0001] This utility model relates to the field of nuclear power cable trays, and in particular to a novel nuclear power cable tray support arm. Background Technology

[0002] Nuclear power cable tray support arms are critical support components specifically designed for cable tray systems in nuclear power plants. Their core function is to provide a stable connection between the cable tray's uprights and the tray itself, and to precisely bear and transfer the weight and load of the cable tray and its internal cables. Due to their application in the unique environment of nuclear power plants, these support arms must meet extremely stringent technical specifications and possess performance far exceeding that of ordinary industrial products. This includes superior load-bearing capacity, excellent corrosion resistance, strong earthquake resistance, and long-term reliability to ensure the safe operation of the cable system throughout the entire lifecycle of the nuclear power plant.

[0003] After the support arm is installed, adjustments are needed due to on-site structural errors. Existing devices typically loosen the bolts with errors for adjustment or add shims to the areas with errors to maintain stability. Furthermore, when laying cables after the cable tray support arm is installed, nuclear power cables need to be strictly classified to prevent signal interference. Existing methods typically use traditional binding to fix different types of cables, resulting in low work efficiency. Therefore, a new type of nuclear power cable tray support arm is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of nuclear power cable tray support arm, which aims to improve the problems of cumbersome adjustment of support arms with errors and cumbersome and troublesome laying of fixed cables in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel nuclear power cable tray support arm, comprising a support, wherein an adjustment mechanism is provided on the inner wall of the support, and a fixing mechanism is provided on the inner wall of the support;

[0006] The adjustment mechanism includes a first threaded rod, a throttle fixedly connected to the left outer wall of the first threaded rod, a threaded block threadedly connected to the outer wall of the first threaded rod, a first hinge sleeve fixedly connected to the inner wall of the top end of the threaded block, a first hinge rod hinged to the inner wall of the first hinge sleeve, a second hinge sleeve hinged to the outer wall of the first hinge rod, a support plate fixedly connected to the outer wall of the top end of the second hinge sleeve, a third hinge sleeve slidably connected to the outer wall of the bottom end of the support plate, a second hinge rod hinged to the inner wall of the third hinge sleeve, and a fourth hinge sleeve hinged to the outer wall of the second hinge rod.

[0007] As a further description of the above technical solution: the fixing mechanism includes a slider, which is slidably connected to the inner wall of the support plate. A fixing block is slidably connected to the inner wall of the slider. A housing is fixedly connected to the outer wall of the top end of the slider. A first clamping block is fixedly connected to the inner wall of the sliding sleeve. A sliding sleeve is slidably connected to the inner wall of the housing. A second threaded rod is threadedly connected to the inner wall of the sliding sleeve. A second clamping block is rotatably connected to the right outer wall of the second threaded rod. A fixing rod is slidably connected to the inner wall of the top end of the housing. The fixing rod is elastically connected to the inner wall of the housing by a spring. A bolt is threadedly connected to the inner wall of the bottom end of the housing.

[0008] As a further description of the above technical solution: the fourth hinge sleeve is fixedly connected to the inner wall of the bracket.

[0009] As a further description of the above technical solution: the support plate is slidably connected to the inner wall of the bracket.

[0010] As a further description of the above technical solution: the inner wall of the sliding sleeve is provided with several sets of fixing slots, and the fixing rod is engaged in the fixing slots.

[0011] As a further description of the above technical solution: the inner side of the fixing block is an inclined surface, and the bolt is in contact with the inclined surface of the fixing block.

[0012] As a further description of the above technical solution: the support plate is provided with a sliding groove, and a gasket is provided on the outside of the fixing block, and the fixing block is in contact with the sliding groove.

[0013] As a further description of the above technical solution: the second clamping block is slidably connected to the inner wall of the outer shell.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, rotating the throttle drives the first threaded rod to rotate, and the threaded block moves along the threaded rod. The first hinge sleeve causes the first hinge rod to move, which in turn drives the second hinge sleeve and the support plate to move. At the same time, the third hinge sleeve and the second hinge rod cooperate to fix the fourth hinge sleeve on the inner wall of the bracket, and the support plate slides on the inner wall of the bracket, thereby realizing the adjustment of the bracket. It can cope with on-site structural errors without disassembling bolts or adding shims. The operation is simple, thus improving the problem of cumbersome adjustment of the support arm with errors in the prior art.

[0016] 2. In this utility model, the rotating bolt is made to contact the inclined surface of the fixing block, pushing the fixing block to slide in the slider. It is fixed by the cooperation of the shim and the sliding groove of the support plate. Then, the fixing rod is released from the fixing slot, and the sliding sleeve is slid to the place closest to the cable. Then, the fixing rod is inserted into the fixing slot of the sliding sleeve under the action of the spring. The second threaded rod is rotated to move in the sliding sleeve, driving the second clamping block to approach the first clamping block and clamp the cable. This realizes the classification and fixing of the cable, improves the work efficiency, and thus improves the problem of cumbersome and troublesome cable laying and fixing in the prior art.

[0026] Reference Figure 2 As shown, the adjustment mechanism 2 includes a first threaded rod 22. The rotation of the first threaded rod 22 drives the movement of the threaded block 23, providing the power for adjustment. A handle 21 is fixedly connected to the left outer wall of the first threaded rod 22, facilitating the rotation of the first threaded rod 22 for adjustment. A threaded block 23 is threadedly connected to the outer wall of the first threaded rod 22. The movement of the threaded block 23 along the first threaded rod 22 drives the first hinge sleeve 24 to transmit motion. The first hinge sleeve 24 is fixedly connected to the inner wall of the top of the threaded block 23. The first hinge sleeve 24 is hinged to the first hinge rod 25, enabling the transmission and conversion of motion. The first hinge rod 25 is hinged to the inner wall of the first hinge sleeve 24, connecting the first hinge sleeve 24 and the second hinge sleeve 29 to transmit motion. The second hinge sleeve 29 is hinged to the outer wall of the first hinge rod 25. The action is transmitted through the first hinge rod 25 and the support plate 28. The top outer wall of the second hinge sleeve 29 is fixedly connected to the support plate 28. The support plate 28 is slidably connected to the inner wall of the bracket 1. The support plate 28 has a sliding groove 211. The support plate 28 slides up and down on the inner wall of the bracket 1 and supports and fixes the subsequently installed cable tray. The bottom outer wall of the support plate 28 is slidably connected to the third hinge sleeve 26. The third hinge sleeve 26 is hinged to the second hinge rod 27 to support the support plate 28 to slide up and down. The inner wall of the third hinge sleeve 26 is hinged to the second hinge rod 27. The second hinge rod 27 connects the third hinge sleeve 26 and the fourth hinge sleeve 210 for auxiliary adjustment. The outer wall of the second hinge rod 27 is hinged to the fourth hinge sleeve 210. The fourth hinge sleeve 210 is fixedly connected to the inner wall of the bracket 1 and supports the second hinge rod 27.

[0027] Reference Figures 3-5As shown, the fixing mechanism 3 includes a slider 39, which slides to support the fixing block 310 on the inner wall of the support plate 28. The slider 39 is slidably connected to the inner wall of the support plate 28. The fixing block 310 is slidably connected to the inner wall of the slider 39. The inner side of the fixing block 310 is inclined, and a gasket is provided on the outer side of the fixing block 310. The fixing block 310 contacts the slide groove 211. The fixing block 310 slides and contacts the slide groove 211 under the push of the bolt 33. The top outer wall of the slider 39 is fixedly connected to the outer shell 31, which provides installation space for accommodating the various components of the fixing mechanism 3. The inner wall of the sliding sleeve 37 is fixedly connected to the first clamping block 32. The first clamping block 32 and the second clamping block 34 cooperate to clamp the cable. The inner wall of the outer shell 31 is slidably connected to the sliding sleeve 37. The inner wall of the sliding sleeve 37 is provided with several sets of fixing slots 311. The sliding sleeve 37 can help the second threaded rod 38 to move quickly to approach the cable and reduce the subsequent rotation time of the second threaded rod 38. A second threaded rod 38 is threadedly connected. When the second threaded rod 38 rotates, it drives the second clamping block 34 to move and clamp the cable. The second clamping block 34 is rotatably connected to the outer right side of the second threaded rod 38. The second clamping block 34 is slidably connected to the inner wall of the outer shell 31. Under the action of the second threaded rod 38, the second clamping block 34 approaches the first clamping block 32 to clamp the cable. A fixing rod 35 is slidably connected to the inner wall of the top of the outer shell 31. The fixing rod 35 is engaged in the fixing slot 311. The fixing rod 35 is engaged in the fixing slot 311 to fix the position of the sliding sleeve 37 and the second threaded rod 38. The fixing rod 35 is elastically connected to the inner wall of the outer shell 31 by a spring 36. The spring 36 provides elastic force to the fixing rod 35 to help it engage in the fixing slot 311 and prevents the fixing rod 35 from falling off accidentally. A bolt 33 is threadedly connected to the inner wall of the bottom of the outer shell 31. The bolt 33 contacts the inclined surface of the fixing block 310. The bolt 33 pushes the fixing block 310 to slide, thereby achieving the cooperation and fixation of the fixing block 310 and the sliding groove 211.

[0028] In use, rotating the handle 21 drives the first threaded rod 22 to rotate, and the threaded block 23 moves along the threaded rod. The first hinge sleeve 24 causes the first hinge rod 25 to move, which in turn drives the second hinge sleeve 29 and the support plate 28 to move. At the same time, the third hinge sleeve 26 and the second hinge rod 27 cooperate to fix the fourth hinge sleeve 210 on the inner wall of the bracket 1, and the support plate 28 slides on the inner wall of the bracket 1, thereby realizing the adjustment of the bracket 1 and can cope with on-site structural errors.

[0029] When it is necessary to fix the cable, rotate the bolt 33 to make it contact the inclined surface of the fixing block 310, push the fixing block 310 to slide in the slider 39, and fix it through the cooperation of the shim and the slide groove 211 of the support plate 28. Release the fixing rod 35 from the fixing slot 311, slide the sliding sleeve 37 to the closest point to the cable, and the fixing rod 35 is locked into the fixing slot 311 of the sliding sleeve 37 under the action of the spring 36. Rotate the second threaded rod 38 to move in the sliding sleeve 37, drive the second clamping block 34 to approach the first clamping block 32 to clamp the cable, and realize the classified fixation.
