Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, specifically to a cable tray clamping device. Background Technology

[0002] When laying cables, construction workers need to place the cables into the cable tray one by one, and straighten, fix and bundle the cables to ensure that the cables are evenly stressed and neatly arranged during operation.

[0003] Currently, installation workers can usually place and arrange light or medium-sized cables relatively easily. However, when dealing with heavy-duty cables with larger diameters and greater weight, due to their greater mechanical strength and rigidity, wire clamping devices are required for installation.

[0004] Most of the wire pressing devices currently in use consist of a wire pressing mechanism and a support frame. However, the structure of the support frame is relatively fixed. When the width of the cable tray body changes, a support frame of different sizes needs to be customized to match the device. This results in low versatility of the device and increases production costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable tray crimping device, so as to solve the problem that most of the existing crimping devices are composed of a crimping mechanism and a support frame. However, the structure of the support frame is relatively fixed. When the width of the cable tray body changes, a support frame of different size needs to be customized to match the use, resulting in low versatility of the device and increased production costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cable tray clamping device, installed on the cable tray body, includes:

[0008] The mounting arm is equipped with jacks for pressing cables into the cable tray body;

[0009] Two support frames are respectively provided on both sides of the cable tray body, and each of the two support frames is provided with a support arm. The two support arms are slidably provided on both sides of the mounting arm to adjust the distance between the two support frames.

[0010] Fasteners are provided on the mounting arm and connected to the two support arms to fix the position of the support arms within the mounting arm.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By installing support frames on both sides of the cable tray body and using sliding support arms, the distance between the two support frames can be flexibly adjusted according to the width of the cable tray, thus adapting to cable trays of different widths. At the same time, by setting jacks on the mounting arms, heavy cables can be pressed into the cable tray using mechanical force during cable laying, which not only reduces the labor intensity of construction workers, but also improves the efficiency of cable laying.

The ends of the two support arms are each provided with threaded blocks, and the two threaded blocks respectively engage with the two ends of the bidirectional lead screw.

[0014] Furthermore, a handle is provided at one end of the bidirectional lead screw.

[0015] Furthermore, the bottom of the support frame is provided with an L-shaped block, which is installed on the side of the cable tray body.

[0016] Furthermore, a rubber pad is provided on the inner side of the L-shaped block, and the rubber pad abuts against the side of the cable tray body.

[0017] Furthermore, a pressure plate is provided on the side of the jack away from the mounting arm. The pressure plate has a mounting groove, and two pressure brackets are slidably mounted in the mounting groove in a mirror image.

[0036] like Figure 1-3As shown in the figure, this utility model embodiment proposes a cable tray pressing device, installed on the cable tray body 10, including a mounting arm 20, two support frames 40, and fasteners 60; the mounting arm 20 is provided with a jack 30 for pressing the cable into the cable tray body 10; the two support frames 40 are respectively provided on both sides of the cable tray body 10, and each of the two support frames 40 is provided with a support arm 50, which is slidably provided on both sides of the mounting arm 20 to adjust the distance between the two support frames 40; the fasteners 60 are provided on the mounting arm 20 and connected to the two support arms 50 to fix the position of the support arms 50 within the mounting arm 20. The jack 30 is a conventional device in the art. This embodiment uses a hand-cranked scissor jack 30 as an example. Since this utility model does not make any improvements to it, its specific structure and working method will not be described in detail here.

[0037] In this embodiment of the invention, during use, the width of the two support frames 40 is first adjusted according to the width of the cable tray body 10. Construction workers can push or pull the two support arms 50 respectively, allowing them to move within the mounting arm 20, thereby increasing the overall length of the mounting arm 20 and the two support arms 50. This allows for adjustment of the distance between the two support frames 40, enabling the bottoms of the two support frames 40 to be installed on both sides of the cable tray body 10. Next, with the cooperation of fasteners 60, after the two support arms 50 are adjusted, they can be fixed using fasteners 60, ensuring the stability of the two support frames 40 after adjustment. Subsequently, construction workers place the cable between the mounting arm 20 and the cable tray body 10, and apply top pressure using jacks 30 to gradually press the cable into the cable tray body 10. This not only reduces the labor intensity of construction workers but also improves the efficiency of cable laying.

[0038] Specifically, such as Figure 2As shown in this embodiment of the present invention, the fastener 60 includes two fixing blocks 61 disposed at both ends of the mounting arm 20 and a bidirectional lead screw 62 rotatably disposed on the two fixing blocks 61. Each end of the two support arms 50 is provided with a threaded block 63, which respectively engages with both ends of the bidirectional lead screw 62. The two threaded blocks 63 are located between the two fixing blocks 61 and are slidably engaged with the mounting arm 20, so that the two threaded blocks 63 can only slide between the two fixing blocks 61 as the bidirectional lead screw 62 rotates, and will not rotate on their own. Furthermore, the two ends of the bidirectional lead screw 62 have threads in opposite directions, so that when the bidirectional lead screw 62 rotates, the threaded blocks 63 at both ends move synchronously in opposite directions, thereby causing the support arms 50 to slide simultaneously outward or inward within the mounting arm 20, achieving rapid and synchronous adjustment of the distance between the two support frames 40, allowing their bottoms to... The threaded block 63 is accurately installed on both sides of the cable tray body 10. After being adjusted to the appropriate position, the threaded block 63 will self-lock under the action of the thread, effectively preventing the two support frames 40 from moving, thereby ensuring the stability of the subsequent wire pressing process. Moreover, one end of the bidirectional screw 62 is provided with a handle 64, which can be manually rotated by the construction personnel to adjust the screw without the need for external tools, making the operation more convenient and efficient. In addition, in practical applications, a locking nut can be added to prevent the counter-impact force generated by the jack 30 on the installation arm 20 during use from causing the connection between the threaded block 63 and the bidirectional screw 62 to loosen and affect its stability. That is, a locking nut is arranged on each side of the threaded block 60. When the bidirectional screw 62 rotates to move the threaded block 63 to the required position, the locking nut is tightened to make it press against the two sides of the threaded block 63, thereby limiting its axial movement and limiting the installation arm 20 to ensure its stability.

[0039] Specifically, such as Figure 2 As shown in this embodiment of the invention, the bottom of the support frame 40 is provided with an L-shaped block 41, which is installed on the side of the cable tray body 10. The shape of the L-shaped block 41 allows it to be easily locked onto the side of the cable tray body 10. With the adjustment of the bidirectional screw 62, the two L-shaped blocks 41 are driven to be locked onto the side of the cable tray body 10. Even when the cable tray body 10 vibrates to a certain extent, the two support frames 40 can still be stably clamped onto the cable tray body 10, ensuring the stability of the jack 30. Moreover, the inner side of the L-shaped block 41 is provided with a rubber pad 42, which abuts against the side of the cable tray body 10. The rubber pad 42 can increase the friction between the L-shaped block 41 and the side of the cable tray body 10, making the support frame 40 more stable during operation and less prone to displacement, thereby ensuring stability.

[0040] Based on the above solutions, such as Figure 1-3As shown in this embodiment of the invention, a pressure plate 70 is provided on the side of the jack 30 away from the mounting arm 20. The pressure plate 70 has a mounting groove, and two pressure frames 71 are slidably mounted in the mounting groove. The two pressure frames 71 are connected by an adjusting member 80, which allows the two pressure frames 71 to move closer to or further away from each other. Before the cable pressing operation, the construction personnel can pull out the two pressure frames 71 in the mounting groove and move them to both sides of the pressure plate 70 to increase the contact area between the pressure plate 70 and the cable, thereby improving the stability and uniformity of force during the cable pressing process. Furthermore, the spacing of the pressure frames 71 can be flexibly adjusted according to the number and arrangement width of the cables on the cable tray body 10, so that it can adapt to cable tray bodies 10 of different widths and specifications.

[0041] Specifically, such as Figure 3 As shown in this embodiment of the utility model, the adjusting member 80 is a bidirectional screw 81, the mounting groove is provided with two mounting blocks 82, the bidirectional screw 81 is rotatably disposed between the two mounting blocks 82, and the two ends of the bidirectional screw 81 are respectively threadedly connected to the two pressure frames 71; wherein, the two ends of the bidirectional screw 81 are external threads in opposite directions, and one end of the pressure frame 71 is provided with an internal thread that meshes with the external thread of the bidirectional screw 81, thereby adjusting the distance between the two pressure frames 71 by rotating the bidirectional screw 81, thereby increasing the contact area between the pressure plate 70 and the cable; subsequently, the construction personnel use the jack 30, and under the joint action of the pressure plate 70 and the pressure frame 71, to smoothly press the cable into the cable tray body 10, ensuring that the heavy cable does not slip during the pressing process; in addition, a limiting part can be provided at one end of the pressure frame 71, the limiting part is engaged with the pressure plate 70, thereby limiting the movement distance of the pressure frame 71 and preventing the pressure frame 71 from disengaging from the bidirectional screw 81 or the pressure plate 70 during the adjustment process.

[0042] Specifically, such as Figure 3As shown in this embodiment of the invention, a first bevel gear 83 and a second bevel gear 84 meshing with each other are provided between the two mounting blocks 82. The first bevel gear 83 is fixedly mounted on the bidirectional screw 81, and the second bevel gear 84 is rotatably mounted on the mounting groove. When the operator rotates the bidirectional screw 81, the second bevel gear 84 drives the first bevel gear 83 to rotate, thereby driving the bidirectional screw 81 to rotate, which in turn causes the two pressure frames 71 to slide in opposite directions to adjust the contact area between the pressure plate 70 and the cable. Furthermore, the pressure plate 70 is provided with a knob 85, one end of which passes through the mounting groove and is connected to the second bevel gear 84. By directly rotating the knob 85 on the pressure plate 70, the connected second bevel gear 84 is driven to rotate. Under the meshing cooperation of the second bevel gear 84 and the first bevel gear 83, the second bevel gear 84 drives the first bevel gear 83 to rotate, which in turn drives the bidirectional screw 81 to rotate. Thus, the forward and reverse rotation of the bidirectional screw 81 can be controlled by rotating the knob 85, making the operation more convenient.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
