Description

Technical Field

[0001] This utility model relates to the field of low-voltage engineering technology, and in particular to a cable tray structure for an indoor low-voltage engineering integrated cabling system. Background Technology

[0002] The design of cable tray structures for indoor low-voltage cabling systems must consider functional requirements, environmental characteristics, and construction specifications. Commonly used cable tray structures include trough-type cable trays, tray-type cable trays, cable duct-type cable trays, and mesh-type cable trays. Among them, trough-type cable trays can effectively protect cables from external environmental influences, reducing the risk of damage and wear, and can effectively prevent dust and moisture. However, trough-type cable trays are relatively heavy and require more support and fixing measures during installation.

[0003] Existing cable trays are supported by multiple support mechanisms, which include a support beam and two hangers. The support beam supports the cable tray from below, and the two hangers are connected at their ends to the end of the support beam and the top of the wall, respectively.

[0004] During the installation of this support and fixing mechanism, to reduce the weight of the hangers during installation, the two hangers are first installed on the top of the wall, and then the two ends of the support beam and the lower ends of the hangers are installed. However, if there is some deviation in the installation position of the two hangers during the installation process, it will be difficult to install the support beam. At this time, the hangers need to be reinstalled and the installation position adjusted, which affects the installation efficiency. In addition, there is usually no fixing component between the support and fixing mechanism and the cable tray, resulting in poor fixing effect. Utility Model Content

[0005] The purpose of this utility model is to provide a cable tray structure for an indoor low-voltage engineering integrated cabling system, which improves installation efficiency and enhances the fixing effect of the trough-type cable tray.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable tray structure for an indoor low-voltage engineering integrated cabling system, comprising a trough-type cable tray body and multiple supporting and fixing mechanisms. The supporting and fixing mechanisms include a supporting beam, two hanging frames slidably connected to both ends of the supporting beam, a first locking member disposed between the hanging frames and the supporting beam, two hanging rods with their upper ends connected to the top of the wall, a connecting member disposed between the lower end of the hanging rod and the hanging frame and adjustable in installation angle, and two limiting components disposed at both ends of the supporting beam and abutting against both sides of the trough-type cable tray body. The length direction of the supporting beam is parallel to the line connecting the center points of the two hanging rods, and the two hanging frames are arranged in parallel. The limiting components include two sliding seats slidably disposed at both ends of the supporting beam, two second locking members threadedly connected to the sliding seats and abutting against the supporting beam for fixing, and two limiting seats hinged to the sliding seats and supporting and limiting both sides of the trough-type cable tray body. The rotation axis of the limiting seats is along the vertical direction, so that the limiting seats can fit against the side of the trough-type cable tray body during rotation.

[0007] By adopting the above technical solution, when installing the support and fixing mechanism, it is only necessary to roughly determine the installation position of the hangers. The lower ends of the two hangers are connected to the assembly with two hanger frames and a support beam through the connector. After the two hangers are installed, the hanger frames are locked by the first locking device. During this process, the hangers do not need to be precisely installed, which improves the installation efficiency. Moreover, during the installation of the support and fixing mechanism, there may be a situation where the length direction of the installation beam is not perpendicular to the length direction of the trough cable tray body. In this case, when the trough cable tray body is laid on multiple support and fixing mechanisms, the position of the sliding seat, the limiting seat, and the second locking device make the limiting seat on the sliding seat abut against both sides of the trough cable tray body for support and limitation, and the sliding seat is fixed by the second locking device, which improves the fixing effect of the trough cable tray body.

[0008] A further feature of this invention is that: the supporting crossbeam has sliding grooves extending along its length and penetrating both ends on both sides; the cross-section of the hanging frame is inverted "U" shape; the two ends of the hanging frame are provided with sliding parts that are slidably connected in the sliding grooves; and the first locking member is a locking bolt that is threadedly connected to the side of the hanging frame and abuts against the side of the supporting crossbeam.

[0009] By adopting the above technical solution, by setting sliding grooves on both sides of the support beam, and setting sliding parts at both ends of the hanging frame that are slidably connected in the sliding grooves, the two hanging frames can be slidably connected to the support beam for combination. At the same time, the first locking member is a locking bolt that is threadedly connected to the side of the hanging frame and abuts against the side of the support beam, so as to achieve the purpose of locking the hanging frame.

[0010] A further feature of this invention is that: a connecting hole is provided in the middle of the hanging frame, the lower end of the hanging rod is a threaded end, the lower end of the hanging rod passes through the connecting hole, and the connecting component includes a first locking nut threadedly connected to the portion of the lower end of the hanging rod that passes through the connecting hole, and a second locking nut threadedly connected to the portion of the lower end of the hanging rod that does not pass through the connecting hole. The first locking nut and the second locking nut respectively abut against the upper and lower surfaces of the middle of the hanging frame.

[0011] By adopting the above technical solution, the lower end of the boom passes through the connecting hole and is connected and fixed by the first locking nut and the second locking nut. At this time, the installation angle of the boom and the frame can be adjusted during the fixing process without restricting the angle of the boom and the frame.

[0012] A further feature of this invention is that the upper end of the boom is provided with a connecting ring having connecting holes arranged in a circumferential array.

[0013] By adopting the above technical solution, the connecting ring at the upper end of the boom can be fixed with multiple expansion bolts or nails, thereby improving the stability of the boom connection.

[0014] A further feature of this invention is that rubber pads extending along the length direction are provided on both sides of the upper surface of the supporting beam, and the rubber pads do not interfere with the movement of the sliding seat.

[0015] By adopting the above technical solution and setting rubber pads, the main body of the trough-type cable tray can achieve a good shock absorption and buffering effect during placement. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Example: A cable tray structure for an indoor low-voltage electrical engineering integrated cabling system, such as... Figure 1 and Figure 2 As shown, it includes a trough-type cable tray body 1 and multiple supporting and fixing mechanisms 2.

[0022] like Figure 1 and Figure 2 As shown, the support and fixing mechanism 2 includes a support beam 2-1, two hanging frames 2-2 slidably connected to both ends of the support beam 2-1, a first locking member 2-3 disposed between the hanging frames 2-2 and the support beam 2-1, two hanging rods 2-4 whose upper ends are connected to the top of the wall, a connecting member 2-5 disposed between the lower end of the hanging rod 2-4 and the hanging frame 2-2 and whose installation angle is adjustable, and two limiting components 2-6 disposed at both ends of the support beam 2-1 and which abut against both sides of the cable tray body 1. Meanwhile, the length direction of the support beam 2-1 is parallel to the line connecting the center points of the two hanging rods 2-4, and the two hanging frames 2-2 are arranged in parallel.

[0023] like Figure 2 and Figure 3 As shown, the support beam 2-1 has sliding grooves 2-1-1 extending along its length and passing through both ends on both sides. The cross section of the hanging frame 2-2 is in the shape of an inverted "U". The two ends of the hanging frame 2-2 are provided with sliding parts 2-2-1 that are slidably connected in the sliding grooves 2-1-1. The first locking member 2-3 is a locking bolt that is threadedly connected to the side of the hanging frame 2-2 and abuts against the side of the support beam 2-1.

[0024] like Figure 2 and Figure 3 As shown, a connecting hole is provided in the middle of the hanging frame 2-2. The lower end of the hanging rod 2-4 is a threaded end 2-4-1, which passes through the connecting hole. The connecting piece 2-5 includes a first locking nut 2-5-1 threadedly connected to the portion of the lower end of the hanging rod 2-4 that passes through the connecting hole, and a second locking nut 2-5-2 threadedly connected to the portion of the lower end of the hanging rod 2-4 that does not pass through the connecting hole. The first locking nut 2-5-1 and the second locking nut 2-5-2 are respectively pressed against the upper and lower surfaces of the middle part of the hanging frame 2-2. A connecting ring 2-4-2 with connecting holes arranged in a circumferential array is provided at the upper end of the hanging rod 2-4.

[0025] like Figure 2 and Figure 3As shown, the limiting assembly 2-6 includes two sliding seats 2-6-1 slidably disposed at both ends of the supporting beam 2-1, two second locking members 2-6-2 threadedly connected to the sliding seats 2-6-1 and capable of being pressed against the supporting beam 2-1 for fixation, and two limiting seats 2-6-3 hinged to the sliding seats 2-6-1 by pins to provide support and limit the sides of the cable tray body 1. The rotation axis of the limiting seats 2-6-3 is along the vertical direction, so that the limiting seats 2-6-3 can fit against the side of the cable tray body 1 during rotation. The second locking member 2-6-2 is a locking bolt threadedly connected to the sliding seat 2-6-1 and capable of being pressed against the supporting beam 2-1.

[0026] like Figure 2 and Figure 3 As shown, rubber pads 2-7 extending along the length direction are provided on both sides of the upper surface of the support beam 2-1. The rubber pads 2-7 do not interfere with the movement of the sliding seat 2-6-1.

[0027] Implementation Results: When installing the support and fixing mechanism 2, only the approximate installation position of the hangers 2-4 needs to be determined. The lower ends of the two hangers 2-4 are connected to the assembly with two hanging frames 2-2 and a supporting beam 2-1 via connector 2-5. After the two hangers 2-4 are installed, the hanging frames 2-2 are locked using the first locking component 2-3. During this process, the hangers 2-4 do not require precise installation, thus improving installation efficiency. Furthermore, during the installation of the support and fixing mechanism 2, the length of the installation beam may increase. When the angular direction is not perpendicular to the length direction of the main body 1 of the cable tray, and the main body 1 of the cable tray is laid on multiple support and fixing mechanisms 2, the positions of the sliding seat 2-6-1, the limiting seat 2-6-3, and the second locking member 2-6-2 are such that the limiting seat 2-6-3 on the sliding seat 2-6-1 abuts against both sides of the main body 1 of the cable tray for support and limitation, and the second locking member 2-6-2 fixes the sliding seat 2-6-1, which has the effect of improving the fixing effect of the main body 1 of the cable tray.

[0028] By providing sliding grooves 2-1-1 on both sides of the supporting beam 2-1, and providing sliding parts 2-2-1 at both ends of the hanging frame 2-2 that are slidably connected within the sliding grooves 2-1-1, the two hanging frames 2-2 can be slidably connected to the supporting beam 2-1 for combination. Simultaneously, the first locking member 2-3 is a threaded connection to the side of the hanging frame 2-2, which is a locking bolt that abuts against the side of the supporting beam 2-1, thus achieving the purpose of locking the hanging frame 2-2. Firstly, the lower end of the hanger rod 2-4 passes through the connecting hole and is connected and fixed by the first locking nut 2-5-1 and the second locking nut 2-5-2. During the fixing process, the installation angle of the hanger rod 2-4 and the hanging frame 2-2 is not restricted, allowing for adjustment of their angles. The connecting ring 2-4-2 at the upper end of the hanger rod 2-4 can be fixed with multiple expansion bolts or nails to improve the stability of the hanger rod 2-4 connection. By providing rubber pads 2-7, the main body 1 of the cable tray provides good shock absorption and cushioning during placement.
