Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a tray-type cable bridge. Background Art

[0002] In traditional cable laying, cables are usually hung on walls or ceilings, or routed through pipes. Tray-type cable trays are designed to solve cable laying and management issues. Tray-type cable trays are a type of equipment used for cable laying that has a structure similar to a tray supporting cables and can be installed on walls or ceilings.

[0003] Currently, most tray-type cable trays are square metal pipes that are hung on walls or ceilings with cables laid inside. However, the cables are not effectively fixed in the tray and are prone to loosening or entanglement. When one end of the cable tray is pulled, the cables will rub against the inner wall of the cable tray, resulting in greater resistance, making it more difficult to adjust the cable position inside the cable tray.

[0004] A tray-type cable tray is now proposed. Utility Model Content

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A tray-type cable tray comprises a cable tray, both ends of which are threadedly installed with connecting mechanisms, the top of which is fixedly connected with a lifting mechanism, the lifting mechanism comprises a base; the connecting mechanism comprises a gasket; the top of the cable tray is fixedly installed with a slide rail, and the interior of the cable tray is fixedly installed with a cable limiting mechanism.

[0007] A further improvement of the technical solution of the utility model is that the cable bridges are spliced ​​by a connecting mechanism.

[0008] A further improvement of the technical solution of the utility model is that: the bottom of the base is rotatably connected with a steel cable, and the bottom of the steel cable is fixedly installed with a lifting ring.

[0009] A further improvement of the technical solution of the utility model is that the base is fixedly installed on the ceiling of the building, and the cable bridge is hoisted on the ceiling of the building by a hoisting mechanism.

[0010] A further improvement of the technical solution of the utility model is that a connecting screw is inserted through one side of the gasket, and the connecting screw penetrates the gasket and is threadedly inserted into a splicing groove.

[0011] A further improvement of the technical solution of the utility model is that the splicing grooves are arranged on the outer surfaces of both sides of the cable tray.

[0012] A further improvement of the technical solution of the utility model is that the cable bridge is provided with a cover plate through the sliding limit of the slide rail at the top.

[0013] A further improvement of the technical solution of the utility model is that a lower clamping plate is fixedly installed on the bottom of the cable limiting mechanism, an upper clamping plate is fixedly installed on the top of the lower clamping plate, springs are fixedly installed on the inner walls of the upper and lower clamping plates, a rotating shaft is fixedly installed on the bottom of the spring, and an arc-shaped fitting wheel is rotatably installed in the middle of the rotating shaft.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] The utility model provides a tray-type cable bridge, which can be transported in modules and quickly spliced ​​on site. It is convenient to transport and install. The two ends of the cable bridge are butt-jointed together, and then a gasket is butt-jointed at a splicing groove of the cable bridge. A connecting screw is passed through the gasket and then screwed into the splicing groove, so that the cable bridges are spliced ​​together.

[0016] The utility model provides a tray-type cable tray, the cover plate of which can be pushed and pulled open by a slide rail installed on the top of the cable tray. After being pulled open, the top of the cable tray is in an open state, which is convenient for maintenance operations on the internal cables. When laying the cables in the cable tray, the cables are passed through the upper clamping plate and the lower clamping plate in sequence. At this time, the arc-shaped fitting wheels on the inner walls of the upper clamping plate and the lower clamping plate will be squeezed by the cables, compressing the springs. At the same time, under the interaction, the arc-shaped fitting wheels always fit the upper and lower surfaces of the cables, so that when one end of the cable is pulled, the cable does not contact and rub against the inner wall of the cable tray. Under the rotation of the arc-shaped fitting wheels, pulling the cables is very labor-saving, and it is very convenient to adjust the position in the cable tray. The upper clamping plate and the lower clamping plate have multiple cable slots, which can fix multiple cables at the same time and separate the cables without entanglement. Under the action of the spring, it is compatible with cables of different thicknesses within a certain range, and can play a fixing role. BRIEF DESCRIPTION OF THE DRAWINGS
