Description

Technical Field

[0001] This utility model relates to the field of engineering construction tooling technology, and in particular to a locking component and a temporary cable tray support and fixing frame. Background Technology

[0002] With the development of bridge construction technology, temporary cable trays, as important support structures in the construction process, directly affect construction efficiency and safety through their installation and fixing methods. Traditional methods for fixing temporary cable tray supports often involve welding or simple bolt connections, but these methods suffer from difficulties in adjustment, inconvenience in disassembly, and unstable fixation. Therefore, adjustable locking devices have gradually emerged in the market for connecting and fixing the support components of temporary cable trays. However, existing locking devices still have shortcomings in terms of adjustment precision and structural stability. For example, some devices struggle to precisely control the distance between connecting components, making them prone to loosening or detachment after long-term use. Furthermore, the anti-detachment structures used in existing technologies to prevent the separation of critical components are relatively simple in design and difficult to adapt to the needs of complex construction environments. Simultaneously, the connection methods between existing devices and trusses or columns are usually quite fixed, lacking flexibility and limiting their application in different construction scenarios. Therefore, developing a locking device that is simple in structure, easy to adjust, and reliable in connection has become an urgent problem to be solved in the current technological field to meet the diverse needs of temporary cable tray support in bridge construction. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology. To achieve the above objective, this utility model adopts the following technical solution:

[0005] Preferably, the fixed cylinder is provided with a distance monitoring hole, which is opened on the side wall of the fixed cylinder.

[0006] Preferably, the distance monitoring hole is a through hole provided on the side wall of the fixed cylinder.

[0007] Preferably, the anti-detachment top plate is fixed to the adjusting threaded rod by welding.

[0008] Preferably, the adjusting thread rod has a trapezoidal thread that matches the internal thread of the adjusting nut.

[0009] Secondly, this utility model embodiment proposes a temporary cable tray support fixing frame for fixing the columns of the temporary cable tray, including a clamping hoop, a truss, and a locking assembly; wherein, at least one side of the truss is connected to the truss connecting seat, the clamping hoop connecting seat is connected to the clamping hoop, and the clamping hoop is fixed on the column.

[0010] Preferably, the clamping hoop is composed of two semi-circular hoop bodies, which are interlocked to form a ring structure.

[0011] Preferably, the clamping hoop is fastened to the clamping hoop connecting seat by two bolts.

[0012] Preferably, the truss connector has a mounting through hole for connecting the truss connector to the truss through the fit between the mounting through hole and the bolt.
