Problems solved by technology

[0002] As an emerging industry, the urban underground comprehensive pipe corridor is being used on a large scale. The trend of power and communication cables entering the corridor is inevitable. The construction of multi-layer cable trays, especially the installation of a large number of bridge brackets, has become the focus of construction. The general method is to use the control line first. , and then use a steel tape to measure the spacing and install them layer by layer. This method of installing the brackets is not only laborious, but also due to the different quality control awareness of different construction personnel, the installed brackets are not at the same level, resulting in bridges and brackets. There is a gap directly in the arm, causing secondary rework and affecting the efficiency of bridge installation

Embodiment 1

[0038] The quick installation device for the supporting arms of cable trays in rows of underground pipe corridors includes a main body assembly 1 and a fixed arm assembly 2. The main body assembly 1 includes a C-shaped channel steel 11, a scale 12 and a magnetic block 13. The length of the scale 12 is Slightly less than the length of the C-shaped channel steel 11, the fixed arm assembly 2 includes a fixed arm 3, a cable tray support arm 4, special-shaped bolts 5, washers 6, nuts 7 and locknuts 8;

[0039] The scale 12 is between the C-shaped channel steel 11 and the magnetic block 13, and the scale 12 is fixed on the side of the C-shaped channel steel 11 by the magnetic block 13;

[0040] One end of the fixed arm 3 is vertically fixedly connected with a fixed plate 31, and the fixed plate 31 is respectively provided with through holes 32 on both sides of the upper and lower parts of the fixed arm 3, and the cable tray support arm 4 is fixedly connected to the fixed arm. 3 lowe...

Embodiment 2

[0055] The difference between embodiment 2 and embodiment 1 is that the groove on the tail end surface of the special-shaped bolt 5 is a cross-shaped groove.

[0056] The present invention proposes the quick installation device for the support arm of the cable bridge in rows in the underground pipe gallery and the beneficial effects of the use method thereof are as follows:

[0057] (1) Speed ​​up the construction progress: the same as the conventional method, use the control line first, and then use a steel tape measure to measure the distance and compare the installation layer by layer. Through the use of special installation devices, all the brackets in the entire pipe gallery can be installed at one time. There is no need to control the layer spacing of the support arms one by one, which greatly improves the working efficiency.

[0058] (2) High economic benefit: adopting this method can save a large number of construction personnel costs and save engineering construction ...

Abstract

The invention discloses a rapid installation device of rows of cable bridge supporting arms in an underground pipe gallery. The device comprises a main body assembly and fixing arm assemblies, whereinthe main body assembly comprises a C-shaped channel steel, a graduated scale and magnetic blocks, wherein the length of the graduated scale is slightly smaller than the length of the C-shaped channelsteel; each fixing arm assembly comprises a fixing arm, the cable bridge supporting arms, a special-shaped bolt, a gasket, a nut body and an anti-loose nut, wherein the graduated scale is arranged between the C-shaped channel steel and the magnetic blocks, the graduated scale is fixed on the side face of the C-shaped channel steel through the magnetic blocks, one ends of the fixing arms are vertically and fixedly connected with a fixing plate; and through holes are formed in two sides, located on the upper parts and the lower parts of the fixing arms, of the fixing plate respectively, and thecable bridge supporting arms are fixedly connected to the lower surfaces of the fixing arms. According to the device, the use method of the rapid installation device of the rows of the cable bridge supporting arms in the underground pipe gallery is simple and convenient, the construction efficiency is high, the construction consistency is good, and the expansion of the fixing arm assemblies is very convenient in the later stage.
