Detailed ways

As shown in Figure 1 and Figure 2, the upper end of the wellhead (the place for maintenance personnel to enter and exit) 4 of the cable trench body 1 is covered with a well cover plate 5, and the left side of the cable trench body 1 is respectively provided with 1-4 cables from bottom to top. layer (in this embodiment, the left side in Fig. 1 is provided with 3 horizontal bars along the up and down direction, i.e. 3 cable layers), and the cable layer is shelved and installed on the horizontal bar of the cable support 2 (this embodiment adopts 3 layers, the left side The space between the cable layer and the right side wall of the cable trench body 1 is the aisle), and each cable layer is made up of 1-10 cables 3 (only 3 cables 3 are drawn in the present embodiment figure).

As shown in Figure 3 and Figure 4, the emergency cable bracket used in the cable trench includes a support frame 20, a remote control car 7, a rotating mechanism, a lifting mechanism, and a counterweight 13; the support frame 20 includes a vertical bar 15 and a horizontal bar 16, The right end of the cross bar 16 is connected to the vertical bar 15 (it can be fixedly connected; it can also be slidably connected, and the sliding connection is adopted: the height of the cross bar 16 can be adjusted, such as Chinese patent 202010482018.5, a cable bracket for power engineering cable trenches ), cross bars 16 are 1-4, and 1-4 cross bars 16 are arranged at intervals from bottom to top (this embodiment adopts 3 cross bars 16); On, the vertical bar 15 of support frame 20 links to each other with lifting mechanism.

Described turning mechanism comprises motor 8, bearing 9, turntable 10, gear 18, toothed ring 19; The lower portion of 10 is a cavity, or groove; gear ring 19 is located in the cavity), the inner side of gear ring 19 is meshed with gear 18, and gear 18 is fixedly connected with the output end of motor (drive motor) 8, and motor 8 Fixedly connected in the housing of remote control car 7; the lower outer surface of turntable 10 is fixedly connected with the inner surface of bearing 9, and the outer side of bearing 9 is fixedly connected with the housing upper end of remote control car 7 (that is, turntable 10 is rotatable). The motor 8 drives the gear 18 to rotate, and then the gear 18 drives the toothed ring 19 that is meshed and connected to the outside to rotate. Thereby lower support plate 11, electric telescopic rod 12, upper support plate 14, support frame 20 are rotated.

The lifting mechanism comprises a lower support plate 11, an electric telescopic rod 12, and an upper support plate 14. The lower side of the lower support plate 11 is fixedly connected with the upper end surface of the turntable 10, and four electric telescopic rods 12 are positioned between the lower support plate 11 and the upper support plate. Between the plates 14, the lower end of the electric telescopic rod 12 is fixedly connected to the upper end surface of the lower support plate 11 (the four electric telescopic rods 12 are respectively located at the four corners of the lower support plate 11), and the telescopic end of the electric telescopic rod 12 (that is: the upper end ) is fixedly connected with the lower end surface of the upper support plate 14; the left end of the upper support plate 14 is fixedly connected with the right side of the vertical bar 15 of the support frame 20.

A counterweight 13 is fixed on the right end of the upper support plate 14 . The counterweight 13 is a metal block, which plays a stable role.

The remote control car 7 adopts existing known technology (Chinese patent application number 202120598505.8 can be used). Electric telescoping link 12 adopts prior known technology.

Use: When the first cable support 2 and the third cable support 2 in the cable trench are normal and intact, but the second cable support 2 is damaged; open the manhole cover 5 and remove the emergency cable support 6 used in the cable trench from The wellhead 4 is placed in the cable trench, and the length direction of the cross bar 16 of the support frame 20 is in the longitudinal direction (front and rear direction) of the cable trench, so that the lateral space of the emergency cable support 6 in the cable trench becomes smaller, which is convenient for use in the cable trench The emergency cable bracket 6 is walking. Start the emergency cable support 6 used in the cable trench, when the emergency cable support 6 used in the cable trench walks to the first cable support 2, start the electric telescopic rod 12 (the electric telescopic rod 12 is retracted), and the support frame 20 Descend so that the lowermost cross bar 16 is below the lowermost cross bar of the cable support 2 fixed on the cable trench wall (the other cross bars are positioned under the corresponding cross bars). Start the motor 8, and the rotating mechanism works to make the support frame 20 rotate 90 degrees (as shown in Figure 1). shown). The emergency cable support 6 in the cable trench continues to the vicinity of the second cable support 2 in the cable trench (because the cables at the second cable support 2 cannot be supported, they are in a drooping state; using rollers 17, the cable 3 can slide on the rollers 17 to prevent damage to the cable 3). Restart the electric telescopic rod 12 (the electric telescopic rod 12 stretches out), the support frame 20 rises to the working position (the height of the second cable support in the original cable trench), and now the cable is shelved on the cross bar 16 of the support frame 20 , stop the work of the emergency cable support 6 used in the cable trench. When the new cable bracket arrives, replace the new cable bracket at the original second cable bracket 2. When changing a new bracing frame, the electric telescopic rod 12 can be started again (the electric telescopic rod 12 stretches out), and the bracing frame 20 rises a little more, and the cable 3 is raised a little again, which is convenient for changing a new bracing frame 2.
