Description

Technical Field

[0001] This invention belongs to the technical field of cable tray installation equipment, and more specifically, it relates to a bidirectional adjustable cable tray quick reinstallation device. Background Technology

[0002] In the field of cable tray installation, traditional cable tray installation methods and structures have many problems, which cause inconvenience to high-altitude operations and affect installation efficiency and quality.

[0003] Difficulty in splicing and adjusting cable trays

[0004] Limited adjustment methods: During the splicing process of traditional cable trays, if the distance between two sets of cable tray components is insufficient, there is often a lack of effective two-way adjustment methods. Usually, the only solution is to disassemble the entire cable tray and readjust its position. This method is extremely inconvenient in high-altitude working environments, not only consuming a lot of time and manpower, but also increasing the operational risks.

[0005] Lack of convenient adjustment structure: Traditional cable trays lack a convenient structure like the one in this invention that allows for bidirectional adjustment via electric drill. This makes it difficult to quickly and accurately complete the splicing of cable tray components when facing different installation spaces and splicing requirements during actual installation, affecting installation efficiency and the rationality of the overall layout.

[0006] Poor adaptability to installation angle

[0007] Fixed-angle connection: Traditional cable trays are connected to the building roof in a relatively fixed manner, and the angles between the mounting bracket and the diagonal brace, and between the diagonal brace and the side mounting bracket, are often not adjustable. This makes the installation process complicated in different building structures or scenarios with special installation angle requirements, and may even fail to meet the installation needs, thus limiting the applicability of cable trays.

[0008] Low ease of installation: Because the angle is not adjustable, installers need to spend a lot of effort to adapt to the fixed connection angle during the installation process, which increases the difficulty and time cost of installation. This inconvenience is even more prominent when working at heights, affecting installation efficiency and safety.

[0009] The installation tools are inconvenient to use.

[0010] Tool securing and operation challenges: Electric drills are a common tool during cable tray installation, but traditional installation methods lack effective mechanisms for securing them. Installers find it difficult to maintain the stability of the drill, leading to inconvenience, reduced work efficiency, and potentially decreased installation accuracy or even safety accidents due to drill wobbling.

[0011] Poor coordination between tools and adjustments: In traditional cable tray installation methods, there is a lack of coordinated design between the electric drill and the cable tray adjustment function. When bidirectional adjustment of the cable tray is required, it is not convenient to use an electric drill to perform the adjustment operation, making the adjustment process cumbersome and further reducing installation efficiency.

[0012] Insufficient stability of cable tray movement

[0013] Lack of support for movement: Traditional cable trays lack an effective bottom support structure when undergoing bidirectional movement adjustments, such as during the movement of a second or third cable tray box. This may cause the cable tray to sway during movement, affecting the adjustment accuracy and reducing the stability of the adjusted cable tray support, posing a safety hazard for subsequent use.

[0014] Inflexible distance control: Traditional cable tray adjustment methods often cannot freely control the movement distance, making it difficult to meet the needs of precise adjustment of cable tray position in different installation scenarios, which affects the quality and overall effect of cable tray installation. Summary of the Invention

[0015] To address the aforementioned technical problems, this invention provides a bidirectional adjustable cable tray quick-installation device, which solves the significant shortcomings of existing cable tray installation technologies in terms of cable tray splicing and adjustment, installation angle adaptability, installation tool usage, and cable tray movement stability, thus failing to meet the demands of modern construction engineering for efficient, precise, and safe cable tray installation.

[0016] To achieve the above objectives, the present invention provides the following technical solution: a bidirectional adjustable cable tray quick-repair device, comprising a cable tray assembly, the cable tray assembly comprising a first cable tray box and a lower cross arm, both ends of the lower cross arm being through-mounted with main threaded brackets, each main threaded bracket being fitted with a diagonal brace, each first cable tray box being mounted on two sets of lower cross arms, the first cable tray box being provided with a second cable tray box and a third cable tray box, a position adjustment mechanism being provided between the second cable tray box, the third cable tray box and the first cable tray box, and the position adjustment mechanism including a drive bracket and a fixed bracket, and an adjustable electric drill fixing mechanism being provided diagonally on both lower cross arms.

[0017] Preferably, each main threaded bracket is fixedly fitted with an upper fixed sleeve at its upper end, and a side mounting bracket is fitted between the lower cross arm and the upper fixed sleeve. A fixed diagonal rod is rotatably mounted on the side of the side mounting bracket, and a diagonal brace is fixedly mounted on the fixed diagonal rod. A mounting bracket is rotatably mounted at the end of the diagonal brace. Two sets of side mounting brackets and an upper structure are installed at both ends of each lower cross arm, and the two sets are at a 90-degree angle to each other.

[0018] Preferably, the electric drill fixing mechanism includes a lower fixing bracket and a side rubber clamp. A first spring is installed between the diagonal intersection of the two lower cross arms and the side rubber clamp. Each lower fixing bracket is fixed below the lower cross arm. A lifting frame is slidably installed on the side of each lower fixing bracket. A second spring is installed between the top of each lifting frame and the top of the lower fixing bracket.

[0019] Preferably, two fixed brackets are fixed to the lower sides of the first cable tray box, and two drive brackets are fixedly connected to the side walls of the second and third cable tray boxes, respectively. A drive screw is rotatably installed on the side wall of each fixed bracket, and the drive screw passes through the outside of the drive bracket. A fixed plate is fixedly installed at the end of each drive screw, and a hexagonal mounting rod is fixed at the end of each fixed plate. A second side groove is opened through the side wall of the second cable tray box, and the second side groove faces the side of the third cable tray box where the drive bracket is installed. A first side groove is opened through both side walls of the first cable tray box. Two sliding support frames are fixed below the first and third cable tray boxes, respectively, and the two sliding support frames are close to the ends of the second and third cable tray boxes. An inner slide rail is opened through the side wall of each lower cross arm, and a sliding support frame is slidably arranged in the two inner slide rails.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In this invention, multiple cable tray assemblies can be horizontally arranged during installation. When the distance between two sets of cable tray assemblies is insufficient, the user can place an electric drill at the electric drill fixing mechanism diagonally opposite the lower horizontal arm, and drive the drive bracket and diagonal brace by starting the electric drill to move the second or third cable tray box. This allows for bidirectional adjustment while the first cable tray box of the main body of the cable tray assembly remains stationary, greatly improving the bidirectional adjustment capability. Furthermore, it eliminates the need to disassemble the entire cable tray assembly and readjust its position, significantly improving the convenience of high-altitude operations.

[0022] In this invention, when installing the cable tray assembly as a whole, the top of the main threaded frame is connected to the top of the building, and then multiple sets of mounting brackets at both ends of the lower cross arm are connected to the top of the building, completing multiple connections. The angle between the mounting bracket and the diagonal brace is adjustable, and the angle between the diagonal brace and the side mounting bracket is adjustable, which can facilitate installation at different angles and greatly improve the ease of installation.

[0023] In this invention, when installing the electric drill, it is placed between the end of the drive screw and the side rubber clamp, with the drill body in close contact with the side rubber clamp. Then, the lower handle of the electric drill is in close contact with the top of the lifting frame. The lifting frame and the side rubber clamp are supported by a first spring and a second spring, respectively, thus maintaining the stability of the electric drill. The user then holds the drill body and starts the drill. The output end of the electric drill is locked with the hexagonal mounting rod at the end of the fixed plate frame, and the drive screw is rotated through the hexagonal mounting rod. By setting the electric drill fixing mechanism on the lower cross arm, it is more convenient for workers to use. Moreover, the electric drill is an essential tool for installing cable tray components, and it is also more convenient to adjust the cable tray components in both directions.

[0024] In this invention, when the electric drill drives the lead screw to rotate, the lead screw and the drive bracket are threaded together. The rotation of the lead screw will drive the drive bracket to move, and the movement of the drive bracket can drive the second or third cable tray box to move. The second and third cable tray boxes are arranged in opposite directions, thus realizing bidirectional movement. Moreover, the use of the lead screw allows for free distance adjustment. At the same time, when the second and third cable tray boxes move, the bottom is supported by two sliding support brackets, which can make them more stable, improve subsequent support capacity, and facilitate quick reinstallation.

A second cable tray box 2 and a third cable tray box 21 are provided on the first cable tray box 19. A position adjustment mechanism is provided between the second cable tray box 2, the third cable tray box 21, and the first cable tray box 19. The position adjustment mechanism includes a drive bracket 24 and a fixed bracket 26. The two lower cross arms... Adjustable electric drill fixing mechanisms are provided at opposite corners of the cable tray assembly 11. During installation, multiple sets of cable tray assemblies 1 can be arranged horizontally. When the distance between two sets of cable tray assemblies 1 is insufficient, the user places the electric drill at the electric drill fixing mechanism at opposite corners of the lower horizontal arm 11. By starting the electric drill, the drive bracket 24 and the diagonal brace 16 are activated to move the second cable tray box 2 or the third cable tray box 21, thereby achieving bidirectional adjustment. The first cable tray box 19 of the main body of the cable tray assembly 1 remains stationary, greatly improving the bidirectional adjustment capability. Moreover, there is no need to disassemble the entire cable tray assembly 1 and readjust its position, which greatly improves the convenience of high-altitude operations.

[0035] Each main threaded bracket 12 is fixedly fitted with an upper fixed sleeve 13 at its upper end. A side mounting bracket 14 is fitted between the lower cross arm 11 and the upper fixed sleeve 13 on the main threaded bracket 12. A fixed diagonal rod 15 is rotatably mounted on the side of the side mounting bracket 14. A diagonal brace 16 is fixedly mounted on the fixed diagonal rod 15. A mounting bracket 17 is rotatably mounted at the end of the diagonal brace 16. Two sets of side mounting brackets 14 and the upper structure are installed at both ends of each lower cross arm 11, and the two sets are at a 90-degree angle to each other. When installing the entire cable tray assembly 1, the top of the main threaded bracket 12 is connected to the top of the building, and then the multiple sets of mounting brackets 17 at both ends of the lower cross arm 11 are connected to the top of the building, completing multiple connections. The angle between the mounting bracket 17 and the diagonal brace 16 is adjustable, and the angle between the diagonal brace 16 and the side mounting bracket 14 is adjustable, which can facilitate installation at different angles and greatly improve the ease of installation.

[0036] The electric drill fixing mechanism includes a lower fixing bracket 32 ​​and a side rubber clamp 3. A first spring 31 is installed between the diagonally opposite intersection of the two lower horizontal arms 11 and the side rubber clamp 3. Each lower fixing bracket 32 ​​is fixed below the lower horizontal arm 11. A lifting frame 34 is slidably installed on the side of each lower fixing bracket 32, and a second spring 33 is installed between the top of each lifting frame 34 and the inner top of the lower fixing bracket 32. When installing the electric drill, the drill is placed between the end of the drive screw 25 and the side rubber clamp 3, with the drill body in close contact with the side rubber clamp 3. Then, the lower handle of the drill and the lifting... The lifting frame 34 is attached to the top, and the lifting frame 34 and the side rubber clamp 3 are supported by the first spring 31 and the second spring 33 respectively, so as to maintain the stability of the electric drill. Then, the user holds the electric drill body and starts the electric drill. The output end of the electric drill is locked with the hexagonal mounting rod 28 at the end of the fixed plate frame 27, and the drive screw 25 is rotated through the hexagonal mounting rod 28. By setting the electric drill fixing mechanism on the lower cross arm 11, it is more convenient for workers to use. The electric drill is an essential tool for the installation of the cable tray assembly 1, and it is also more convenient to adjust the cable tray assembly 1 in both directions.

[0037] Two fixed brackets 26 are respectively fixed to the lower sides of the first cable tray box 19, and two drive brackets 24 are respectively fixedly connected to the side walls of the second cable tray box 2 and the third cable tray box 21. A drive screw 25 is rotatably mounted on the side wall of each fixed bracket 26, and the drive screw 25 passes through the drive bracket 24. A fixed plate frame 27 is fixedly mounted at the end of each drive screw 25, and a hexagonal mounting rod 28 is fixed at the end of each fixed plate frame 27.

Two side grooves 22 are formed through the two side walls of the first cable tray box 19. Two sliding support frames 18 are fixed below the third cable tray box 21 of the first cable tray box 19, and both sliding support frames 18 are close to... At the ends of the second cable tray box 2 and the third cable tray box 21, each lower cross arm 11 has an inner slide rail 29 extending through its side wall. A sliding support frame 18 is slidably installed within each of the two inner slide rails 29. When the electric drill drives the drive screw 25 to rotate, the drive screw 25 and the drive bracket 24 are threaded together. The rotation of the drive screw 25 causes the drive bracket 24 to move, which in turn moves either the second cable tray box 2 or the third cable tray box 21. The second cable tray box 2 and the third cable tray box 21 are arranged in opposite directions, thus enabling bidirectional movement. The drive screw 25 allows for free distance adjustment. Furthermore, when the second cable tray box 2 and the third cable tray box 21 move, their bottoms are supported by two sliding support frames 18, providing greater stability, improving subsequent support capabilities, and facilitating rapid reinstallation.

[0038] The cable tray assembly 1 is the core main structure of the equipment and the basic framework of the entire bidirectional adjustable cable tray quick replacement equipment. It includes multiple components such as the first cable tray box 19 and the lower cross arm 11. It can realize the functions of cable tray installation, fixation and bidirectional adjustment, and plays a role in supporting and connecting cables in high-altitude operations.

[0039] The lower cross arm 11 is an important component of the cable tray assembly 1. It is arranged laterally and mainly serves to support and connect other components. The main threaded bracket 12 is installed through both ends of the lower cross arm, and adjustable electric drill fixing mechanisms are provided at the diagonal corners. The side wall is also provided with an inner slide rail 29, which provides a structural basis for the installation and adjustment of the equipment.

[0040] The main threaded bracket 12 is a threaded frame that runs through both ends of the lower cross arm 11. Its upper end connects to the top of the building and is one of the key components supporting the entire cable tray assembly 1. Through cooperation with other components, it provides stable vertical support for the cable tray assembly 1.

[0041] The upper fixed sleeve 13 is fixedly sleeved on the upper end of the main thread frame 12, located above the lower cross arm 11. It mainly plays the role of fixing and limiting, and can enhance the stability of the connection between the main thread frame 12 and the lower cross arm 11.

[0042] The side mounting bracket 14 is sleeved on the main threaded bracket 12 located between the lower cross arm 11 and the upper fixed sleeve 13. A fixed diagonal rod 15 is rotatably mounted on its side. It is an intermediate component connecting the main threaded bracket 12 and the fixed diagonal rod 15, and provides installation support for the fixed diagonal rod 15 and other structures.

[0043] The fixed diagonal brace 15 is rotatably mounted on the side of the side mounting bracket 14, and a diagonal brace 16 is fixedly mounted on it, which plays the role of transmitting force and connecting, connecting the diagonal brace 16 to the side mounting bracket 14, and jointly enhancing the stability of the cable tray assembly 1.

[0044] The diagonal brace 16 is fixedly installed on the fixed diagonal brace 15, and a mounting bracket 17 is rotatably installed at its end, forming an oblique support structure in conjunction with other components. The angle between it and the side mounting bracket 14 is adjustable to adapt to different installation angle requirements and enhance the overall stability of the cable tray assembly 1.

[0045] The mounting bracket 17 is rotatably mounted on the end of the diagonal brace 16. When installing the cable tray assembly 1, it is connected to the top of the building. Through the connection of multiple sets of mounting brackets 17, multiple connections between the cable tray assembly 1 and the top of the building are realized, which further improves the installation stability of the equipment. Moreover, the angle between it and the diagonal brace 16 is adjustable, which facilitates installation at different angles.

[0046] The sliding support frame 18 is fixed below the first cable tray box 19 and the third cable tray box 21, respectively, and is located near the ends of the second cable tray box 29 and the third cable tray box 21. It is slidably disposed within the inner slide rail 29 on the side wall of the lower cross arm 11. When the second cable tray box 29 and the third cable tray box 21 move, it plays a supporting role, ensuring their stability during movement and improving subsequent support capacity.

[0047] The first cable tray box 19 is the main body of the cable tray assembly 1, mounted on two sets of lower cross arms 11. A second cable tray box 2 and a third cable tray box 21 are positioned above it. Fixed brackets 26 from the position adjustment mechanism are fixed to the lower sides on both sides. First side grooves 22 penetrate both side walls. It remains stationary during bidirectional adjustment, providing a reference and support for the adjustment of other cable tray boxes.

[0048] The second cable tray box 2 is positioned above the first cable tray box 19. Its side wall is fixedly connected to the drive bracket 24 in the position adjustment mechanism. A second side groove 23 is provided through the side wall, and the second side groove 23 faces the side of the third cable tray box 21 where the drive bracket 24 is installed. It can move under the drive of the position adjustment mechanism, and cooperates with the third cable tray box 21 to achieve bidirectional adjustment.

[0049] The third cable tray box 21 is also located above the first cable tray box 19, facing opposite to the second cable tray box 2. Its side wall is also fixedly connected to the drive bracket 24 in the position adjustment mechanism, and a sliding support bracket 18 is fixed below it. Driven by the position adjustment mechanism, it can move in the opposite direction to the second cable tray box 2, thus achieving bidirectional adjustment.

[0050] The first side groove 22 is formed through both side walls of the first cable tray box 19, possibly to facilitate the passage of cables or the installation and operation of other components, thus providing convenience for the use of the equipment.

[0051] The second side slot 23 is formed through the side wall of the second cable tray box 2 and faces the side where the drive bracket 24 is installed in the third cable tray box 21. Its function may be similar to that of the first side slot 22, which facilitates cable arrangement or related operations.

[0052] The drive bracket 24 is a component of the position adjustment mechanism. It is fixedly connected to the side walls of the second cable tray box 2 and the third cable tray box 21, and is pierced by the drive screw 25. Under the rotation of the drive screw 25, it will drive the second cable tray box 2 or the third cable tray box 21 connected to it to move, and is a key component for realizing the position adjustment of the cable tray box.

[0053] The drive screw 25 is the core drive component of the position adjustment mechanism. It is rotatably mounted on the side wall of the fixed bracket 26, passes through the drive bracket 24, and is threadedly engaged with the drive bracket 24. Driven by the electric drill, it rotates and drives the drive bracket 24 to move through the threaded transmission, thereby realizing the movement of the second cable tray box 2 or the third cable tray box 21. The movement distance can be freely adjusted.

[0054] The fixed bracket 26 is part of the position adjustment mechanism. The two fixed brackets 26 are fixed to the lower sides of the first cable tray box 19 respectively. The drive screw 25 is rotatably installed on its side wall to provide installation and support for the drive screw 25 and ensure its stable rotation.

[0055] The fixed plate frame 27 is fixedly installed at the end of each drive screw 25, and a hexagonal mounting rod 28 is fixed at the end, which serves to connect the drive screw 25 and the hexagonal mounting rod 28, and transmit the power transmitted by the hexagonal mounting rod 28 to the drive screw 25, causing it to rotate.

[0056] The hexagonal mounting rod 28 is fixed to the end of the fixed plate frame 27 and can be locked with the output end of the electric drill. When the electric drill is started, the hexagonal mounting rod 28 drives the fixed plate frame 27 and the drive screw 25 to rotate, which is a key component for transmitting the power of the electric drill.

[0057] The inner slide rail 29 is opened through the side wall of the lower cross arm 11, and the sliding support frame 18 is slidably installed therein, providing guidance and track for the movement of the sliding support frame 18, and ensuring that the sliding support frame 18 drives the cable tray box to move stably.

[0058] The side rubber clamp 3 is a component of the electric drill fixing mechanism, and a first spring 31 is installed between the two lower cross arms 11 at their diagonal intersections. When installing the electric drill, the drill body is in close contact with the side rubber clamp 3, and the elastic force of the first spring 31 is used to fix the electric drill laterally, maintaining the stability of the electric drill.

[0059] The first spring 31 is installed between the two lower cross arms 11 at their diagonal intersection and the side rubber clamp 3, providing elastic support for the side rubber clamp 3 so that the side rubber clamp 3 can fit tightly against the drill body and enhance the stability of the drill.

[0060] The lower fixed bracket 32 ​​is fixed below the lower cross arm 11, and a lifting frame 34 is slidably installed on its side, providing a mounting base for the lifting frame 34 and the second spring 33. It is an important support component of the electric drill fixing mechanism.

[0061] The second spring 33 is installed between the top of the lifting frame 34 and the top of the lower fixed bracket 32, providing upward elastic support for the lifting frame 34, so that the lifting frame 34 can fit tightly against the lower handle of the electric drill, assisting in fixing the electric drill and enhancing the stability of the electric drill during use.

[0062] The lifting frame 34 is slidably mounted on the side of the lower fixed bracket 32, and a second spring 33 is installed between its top and the inner top of the lower fixed bracket 32. When installing the electric drill, the lower handle of the electric drill is in close contact with the top of the lifting frame 34. Under the action of the second spring 33, the lower handle of the electric drill is supported and fixed, and together with the side rubber clamp 3, the electric drill is kept stable.
