Description

Technical Field

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

[0002] Cable trays are devices used to fix and place cables. They are widely used in industrial fields such as construction, communications, chemical industry, and transportation. They are widely used. Cable trays are divided into trough type, tray type and ladder type. Ladder type cable trays are mainly used for laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems. They have good effects on shielding interference of control cables and protecting cables in heavy corrosion environments.

[0003] Cable trays are often divided into multiple sections and then fixedly connected by multiple sets of bolts. This connection method requires the installation of multiple sets of bolts, which is time-consuming and labor-intensive. In addition, using bolts alone to maintain the fixed relationship between the two cable trays can easily loosen the bolts, resulting in an unstable connection between the two cable trays and a lack of stability. Utility Model Content

[0004] The purpose of the utility model is to address the defects of the existing technology and provide a ladder-type cable tray with fast assembly to solve the problem of fixed connection of two adjacent cable trays by multiple sets of bolts. This connection method requires the installation of multiple sets of bolts, and the installation of multiple sets of bolts is time-consuming and labor-intensive. Moreover, the fixed relationship between the two cable trays is maintained only by bolts, which can easily loosen the bolts, resulting in an unstable connection between the two cable trays and a problem that stability cannot be guaranteed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A fast-assembly ladder-type cable tray, comprising a tray body and a connecting mechanism for connecting two adjacent tray bodies, the tray body comprising two oppositely arranged tray side plates, a plurality of equally spaced cross arms being provided between the two tray side plates, fixing columns being provided at both ends of the tray side plates, a first fastening groove being provided through the fixing columns, a fixing groove for plugging into the fixing columns on the adjacent tray bodies being provided on the tray side plates on one side of the fixing columns, second fastening grooves being provided on both sides of the top end surfaces of the tray side plates being connected to the fixing grooves, and guide blocks being symmetrically provided on both sides of the inner and outer end surfaces of the tray side plates;

[0007] The connecting mechanism includes a connecting plate, and fastening plates for inserting into the first fastening groove and the second fastening groove are symmetrically provided on both sides of the bottom end surface of the connecting plate. Both sides of the connecting plate are folded downward to form symmetrical baffles, and a guide groove adapted to the guide block is opened on the inner end surface of the baffle.

[0008] As a preferred technical solution of the present invention, the fixing columns at both ends of the bridge side plates are staggered with each other.

[0009] As a preferred technical solution of the present invention, a first connecting hole for inserting a connecting bolt is opened on the bottom end surface of the fastening plate, and a second connecting hole connected to the first connecting hole is opened on the bottom end surface of the bridge frame side plate.

[0010] As a preferred technical solution of the present invention, the connecting plate, the fastening plate and the baffle are an integrally formed structure.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When in use, first align the fixing column on the bridge body with the fixing groove on the adjacent bridge body and insert them. When the fixing column is inserted into the bottom of the fixing groove, the first fastening groove on the fixing column is connected to the second fastening groove, thereby preliminarily fixing the two adjacent bridge bodies. Then, the connecting mechanism is pressed onto the connection between the two adjacent bridge bodies. The guide groove on the baffle is aligned with the guide block on the two adjacent bridge bodies and inserted. During the process of inserting the guide block into the guide groove, the fastening plate in the connecting mechanism is inserted into the connected first fastening groove and second fastening groove, so that the first connecting hole on the fastening plate is connected to the second connecting hole on the bridge body, thereby tightly connecting the two adjacent bridge bodies. Finally, the connecting bolt is inserted into the connected first connecting hole and second connecting hole for fixing, thereby further improving the stability of the connection between the two adjacent bridge bodies. The utility model improves the assembly efficiency between the two adjacent bridge bodies and improves the connection strength and stability between the two adjacent bridge bodies by coordinating the setting of the connecting mechanism with the various components on the bridge body.
