Butt joint structure for mounting main beam of coil holder

Abstract

The invention relates to a coil holder main beam installation butt joint structure which comprises a first coil holder main beam and a second coil holder main beam, a positioning insertion block is fixedly connected to the side, close to the second coil holder main beam, of an inner cavity of the first coil holder main beam, and a positioning insertion block is also fixedly connected to the side, away from the first coil holder main beam, of an inner cavity of the second coil holder main beam. The upper side and the lower side of the front end face and the rear end face of the first wire frame main beam are both connected with fixing bases, each fixing base is connected with a rod body, the outer face of each rod body is provided with a positioning recess, and the upper side and the lower side of the front end face and the rear end face of the second wire frame main beam are both fixedly connected with fixing cylinders matched with the rod bodies. An open hole matched with the positioning recess is formed in the surface of each fixed cylinder in a penetrating manner; and a positioning clamping part is arranged at the position, corresponding to the position of the open hole, of the outer surface of each fixed cylinder. According to the cabling rack, the two main beams of the cabling rack can be firmly fixed, the two main beams of the cabling rack can be always located on the same horizontal plane, and therefore normal use and use safety of the cabling rack are guaranteed.

Description

Technical field [0001] The present invention relates to the field of wire frame technology, in particular to a wire frame main girder mounting docking structure. Background [0002] Cable tray, also known as cable tray, is a special equipment used in the machine room to carry out the wire, refers to the machine room after entering the telecommunications, Network Communication, radio and television machine room through the cable frame cloth light, cable into the terminal equipment, for tying light, cable with iron frame. There are two types of cable racks: indoor cable lines and outdoor cable racks. The indoor cable frame is mainly made of high-quality steel or aluminum alloy materials, and has undergone surface treatment methods such as oxidation-resistant spraying or galvanized paint. The outdoor cable trunket is mainly made of steel and is hot-dip galvanized. The cable frame is mainly used for the laying of various types of cables inside and outside the machine room and base st...

Problems solved by technology

In the process of installation and docking of the main beam of the cable rack in the prior art, connecting plates are usually used to fix the two sides of the two main beams respectively, and the two ends of the connecting plate are respectively screwed and fixed to the main beam by bolts. The fastness of the method is not good, so that the bolts connected to the main beam of the cable rack are easy to loose due to the gravity of itself and the cable when the cable rack is in use, resulting in a gap between the main beams of the two cable racks. There is a height difference between them, which seriously affects the safety of the use of the cable rack. In order to overcome the above problems, we propose a butt joint structure for the installation of the main beam of the cable rack
