Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a quick-connect mechanical connector for installing power engineering cable trays. Background Technology

[0002] Cable trays are support systems used in electrical engineering to support, protect, and manage cables and wires. They are typically made of metal, plastic, or other durable materials and offer advantages such as a wide variety of types, broad application, high strength, lightweight structure, low cost, simple construction, flexible wiring, standardized installation, and aesthetically pleasing appearance. They are widely used in building interiors, industrial facilities, and other locations to ensure the safety, aesthetics, and reliability of cable wiring. The main types include trough-type cable trays, tray-type cable trays, and ladder-type cable trays. Mechanical connectors are used for quick assembly during cable tray installation.

[0003] A search revealed a novel cable tray connector with announcement number CN215580174U. This connector comprises two cable tray bodies located inside a frame, and multiple limiting mechanisms located on both sides of the frame. Each limiting mechanism includes a sliding plate and a limiting post. Sliding grooves are symmetrically formed on both sides of the frame. The sliding plate is located inside the sliding groove, and one end of the limiting post is fixedly connected to the sliding plate. The limiting post is located on the cable tray body. A pushing mechanism is provided inside the sliding groove, comprising a fixed rod and a spring. Two circular grooves are formed on one side of the inner wall of the sliding groove, and one end of the fixed rod is slidably inserted into the inner cavity of the circular groove.

[0004] Based on the aforementioned patents, the existing technology has the following shortcomings: Existing cable trays use an elastic snap-fit ​​fixing method involving a frame, sliding plate, limiting post, fixing rod, spring, and pulling rod for rapid splicing. While this achieves rapid splicing, its stability is poor. When external vibrations occur, the cable tray vibrates accordingly, affecting the stability of the entire cable tray support system. Therefore, there is an urgent need to design a rapid splicing mechanical connector for power engineering cable tray installation to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-connect mechanical connector for installing cable trays in power engineering, so as to solve the problems mentioned in the background art.

[0006] The present invention adopts the following technical solution:

[0007] A quick-connect mechanical connector for installing cable trays in power engineering includes a U-shaped support arm. The U-shaped support arm has a support platform inside and a lifting assembly for adjusting the height of the support platform. Two cable tray bodies are attached to the top of the support platform. Each of the two cable tray bodies has equidistant second positioning holes at one bottom end. A vertical positioning assembly for reinforcing the second positioning holes is provided on the support platform. Each of the two cable tray bodies has a first positioning hole at one end of its outer side wall, and a horizontal positioning assembly for reinforcing the first positioning holes is provided on the support platform.

[0008] The above technical solutions enable snap-fit ​​mechanical connectors, which can quickly fix cable trays and ensure their stability.

[0009] The present invention is further configured such that the lifting assembly includes threaded columns rotatably connected to the inner walls of both sides of the U-shaped support arm, and transmission wheels are fixedly installed on the bottom of the outer walls of the threaded columns. A transmission belt is connected to the two transmission wheels. A through hole is opened at one end of the bottom of the U-shaped support arm. A second rotating shaft passing through the through hole is fixed at the bottom of one of the threaded columns. Lifting sleeves are screwed onto both threaded columns, and the support platform is fixed between the two lifting sleeves.

[0010] The above technical solutions allow for adjustment of the support platform's height, enabling the cable tray to be installed at the desired height and ensuring its balance.

[0011] The present invention is further configured such that the transverse positioning component includes a U-shaped groove formed in the middle of the support platform, and a bidirectional screw is rotatably connected to the middle of the inner wall of the U-shaped groove. Both ends of the outer wall of the bidirectional screw are screwed with movable sleeves. The top of each of the two movable sleeves is fixed with a clamping plate that fits against the top surface of the support platform. A plurality of first positioning pins are fixed on one side of each clamping plate. The positions of the first positioning pins correspond to the positions of the first positioning holes. A rotating component for driving the bidirectional screw to rotate is installed on the support platform.

[0012] The above technical solutions facilitate the lateral clamping and positioning of cable trays.

[0013] The present invention is further configured such that the rotating component includes a mounting hole formed on the support platform, and the mounting hole communicates with the U-shaped groove. A first rotating shaft is rotatably connected to the inner wall of the mounting hole. A bevel gear is fixedly installed on one end of the first rotating shaft and the outer wall of the bidirectional screw, and the two bevel gears mesh with each other.

[0014] The above technical solutions facilitate the operation of the lateral positioning components.

[0015] The present invention is further configured such that a turntable is fixed to the other end of the first rotating shaft and the bottom end of the second rotating shaft, and a reinforcing component for reinforcing the first rotating shaft and the second rotating shaft is provided on one side of the outer wall of the support platform and at one bottom end of the U-shaped support arm.

[0016] The above technical solutions facilitate the rotation of the first and second rotating shafts via the turntable, making it convenient to adjust the lifting and lateral positioning components.

[0017] The present invention is further configured such that the reinforcing component includes a reinforcing sleeve fixed to one side of the outer wall of the support platform and one bottom end of the U-shaped support arm, and the reinforcing sleeve is provided with a screw hole, and a reinforcing screw is screwed into the inner wall of the screw hole.

[0018] The above technical solutions can lock the first and second rotating shafts, making the lifting assembly and the lateral positioning assembly more stable after adjustment.

[0019] The present invention is further configured such that the vertical positioning component includes mounting grooves formed on both sides of the top of the support platform, and the inner walls of the mounting grooves are fitted with movable plates. The top of each movable plate is fixed with second positioning pins distributed at equal intervals, the positions of the second positioning pins corresponding to the positions of the second positioning holes. Through holes are formed on both sides of the bottom of the mounting grooves, and a U-shaped tie rod passing through the through hole is fixed to the bottom of the movable plate. Springs are fixedly installed on both sides of the bottom of the movable plate and the bottom of the mounting groove.

[0020] The above technical solutions facilitate the rapid pre-assembly of cable trays, preventing lateral vibration problems.

[0021] The present invention is further configured such that the width of the U-shaped support arm is greater than the width of the cable tray body, and the U-shaped support arm is disposed at the joint of the two cable tray bodies.

[0022] The above technical solutions enable the entire connector to be adapted to cable trays of different widths.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. The quick-connect mechanical connector for cable tray installation in this power project utilizes a U-shaped pull rod within the vertical positioning assembly to pull the movable plate and the second positioning pin downwards. Once the cable tray body is placed on the support platform, the U-shaped pull rod is released, and the spring's reset action drives the movable plate and the second positioning pin to reset, causing the second positioning pin to engage with the second positioning hole on the cable tray body. This facilitates rapid pre-connection of the cable trays to be installed, preventing lateral vibration issues.

[0025] 2. The quick-connect mechanical connector for cable tray installation in this power engineering project utilizes a rotating component to drive the bidirectional screw within the transverse positioning component to rotate, shortening the distance between the two movable sleeves and the two clamping plates. This allows the clamping plates to fit against both sides of the cable tray body, and also allows the first positioning pin to engage with the first positioning hole on the cable tray body. This achieves a snap-fit ​​mechanical connector, preventing longitudinal vibration and thus quickly fixing the cable tray. It replaces the elastic snap-fit ​​fixing method in existing technologies, ensuring the stability of the cable tray and preventing vibration caused by external forces, thereby ensuring the stability of the entire cable tray support system.

[0026] 3. The quick-connect mechanical connectors for cable tray installation in this power project can splice and fix cable trays of different widths, and can adjust the height of the support platform under the action of the lifting components, so as to facilitate the installation of cable trays at the required height and ensure the balance of the cable trays.
