Description

Technical Field

[0001] The utility model belongs to the technical field of cable trays, and particularly relates to a civil lightweight cable tray for industrial factory areas. Background Art

[0002] A cable tray is a metal or non-metal structure used to support and protect power and communication cables; it is usually composed of brackets, cross arms and installation accessories, etc., and can be erected independently or laid on various building and pipe gallery brackets; the design of the cable tray should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance, and all parts need to be galvanized. Especially for the cable trays installed outdoors outside buildings, if they are located near the sea or belong to a corrosion area, the material must have physical properties such as anti-corrosion, moisture resistance, good adhesion and high impact resistance.

[0003] The existing cable trays are not convenient for positioning and wiring cables, resulting in the cables being randomly distributed inside the trays, which easily causes the cables to be entangled and short-circuited and is not conducive to inspection and maintenance. Content of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a civil lightweight cable tray for industrial factory areas, effectively solving the problems that the existing cable trays are not convenient for positioning and wiring cables, resulting in the cables being randomly distributed inside the trays, which easily causes the cables to be entangled and short-circuited and is not conducive to inspection and maintenance.

[0005] To achieve the above object, the utility model provides the following technical solution: A civil lightweight cable tray for industrial factory areas, including a support plate, on the top of which a tray body is fixedly installed. At both ends of the inner bottom of the tray body, lower clamping strips are fixedly installed. Above the two lower clamping strips, upper clamping strips are arranged. On the mutually close sides of the two lower clamping strips and the two upper clamping strips, a number of clamping grooves are opened. At both ends of the two upper clamping strips, positioning sliders are fixedly installed. At both ends of both sides of the tray body, positioning chutes are opened. The four positioning sliders are slidably installed inside the four positioning chutes. At the ends of the positioning sliders away from the upper clamping strips, limit plates are fixedly installed. Between the upper parts of the two upper clamping strips, a pressing transmission assembly is provided.

[0006] Preferably, the pressing transmission assembly includes a first bushing fixedly installed on the upper part of the middle of one side of the bridge body. A first shaft is rotatably installed inside the first bushing. One end of the first shaft is fixedly installed with a rotary handwheel. The end of the first shaft away from the rotary handwheel extends into the bridge body and is fixedly installed with a worm. One end of the worm is fixedly installed with a rotating rod. The end of the rotating rod away from the worm is rotatably installed with a shaft seat. One end of the shaft seat is fixedly connected to the inner wall of one side of the bridge body. A third bushing is rotatably installed on the surface of the first shaft. A second fixing rod is fixedly installed on the upper part of the third bushing. One end of the second fixing rod is fixedly connected to the inner wall of the other side of the bridge body.

[0007] Preferably, a worm gear is meshed with the upper part of the worm. A second shaft is fixedly installed in the middle of the worm gear. Four second bushings are rotatably installed on the surface of the second shaft. First fixing rods are fixedly installed on the upper parts of the second bushings. The ends of the first fixing rods away from the second bushings are fixedly connected to the upper part of one side of the bridge body. First bevel gears are fixedly installed at both ends of the second shaft.

[0008] Preferably, second bevel gears are meshed with one side of the first bevel gears respectively. Threaded rods are fixedly installed at the bottoms of the second bevel gears. Threaded sleeves are respectively threadedly connected to the surfaces of the threaded rods. The bottoms of the two threaded sleeves are fixedly connected to the tops of the two upper clamping strips respectively.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: When in use, the operator neatly places the cable in the clamping grooves on the two lower clamping strips, and then the operator rotates the rotary handwheel to drive the first shaft to rotate along the inside of the first bushing and the third bushing. When the first shaft rotates, it drives the worm gear to rotate through the worm. When the worm rotates, it drives the rotating rod to rotate along the shaft seat, increasing the stability of the worm during rotation;

[0010] When the worm gear rotates, it drives the second shaft to rotate along the inside of the four second bushings. When the second shaft rotates, it drives the two second bevel gears to rotate through the two first bevel gears. When the two second bevel gears rotate, they both drive the threaded sleeves to move downward through the threaded rods. When the threaded sleeves move downward, they both drive the upper clamping strips to move downward. When the upper clamping strips move downward, they both drive the positioning sliders to slide along the inside of the positioning chutes, increasing the stability of the upper clamping strips during movement. When the upper clamping strips move downward, they both press the cable against the lower clamping strips, thereby positioning and distributing the cable; making this cable bridge convenient for positioning and wiring the cable, avoiding the cable from being randomly distributed inside the bridge, thus avoiding cable entanglement and short circuit and facilitating inspection and maintenance.
