[0011] A method for using a cable support mechanism for a fiber composite jacking pipe, the method comprising the following steps:

[0012] S1. Fix the arc-shaped support block to the inside of the fiber composite jacking pipe by bolts, and then install the support connector and the hollow support to the arc-shaped support block;

[0013] S2. Push the limit block upward to compress the limit telescopic rod and the limit spring, slide the suspension frame into the hollow bracket, and release the limit block after the suspension frame slides to the specified position. The limit spring resets to extend the limit telescopic rod, and the limit block moves downward and pops into the limit slot. At this time, the suspension frame is installed;

[0014] S3. Place the cable on the hanging frame. When the jacking work of the fiber composite jacking pipe is completed, push the limit block upward to make the limit block disengage from the limit groove, then slide the hanging frame out of the hollow bracket, and then remove the hollow bracket and the arc support block from the fiber composite jacking pipe in turn.

[0015] The specific steps of step S2 are as follows:

[0016] Press the mounting plate to make the mounting column slide downward in the mounting groove, compress the buffer spring, and at the same time push the limit block upward to compress the limit spring and the limit telescopic rod, align the slide groove of the suspension frame with the connecting plate and slide into the hollow bracket, release the limit block after the suspension frame contacts and pushes the cylindrical block to move synchronously to the specified position, the limit spring resets to extend the limit telescopic rod, the limit block moves downward and bounces into the limit groove, the reset spring compresses and makes the cylindrical block abut against one side of the suspension frame.

[0017] A pressure-triggered alarm is installed on the inner top wall of the support frame, and the pressure-triggered alarm is arranged relative to the cylindrical block;

[0018] When the pressure triggers the alarm, observe the position of the suspension bracket. If the suspension bracket slides out of the support bracket, it means that the limit block has failed and you need to replace the limit block, limit spring and limit telescopic rod. If the suspension bracket moves down for a certain distance, it means that the weight of the cable is too heavy and you need to remove the existing suspension bracket and hollow bracket and replace them with ones with larger load-bearing capacity.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In a cable support mechanism for a fiber composite jacking pipe and a method for using the same, an arc-shaped support block is arranged in the jacking pipe, and a hollow bracket is connected to the arc-shaped support block through a bracket connector, replacing the traditional welding method. At the same time, a suspension frame for storing cables is installed on the hollow bracket in a sliding manner, which is convenient to install. After the suspension frame is moved into place, the horizontal limit of the suspension frame is achieved by inserting the limit block into the limit groove. At the same time, the limit block is applied with force to the limit block by the limit telescopic rod and the limit spring, so that the limit block limits the suspension frame in the vertical direction. The suspension frame is fixed by limiting in two different directions. When the suspension frame needs to be disassembled, the limit block only needs to be pushed to disengage from the limit groove, and the suspension frame can slide out from the hollow bracket. Therefore, the present invention is convenient to use and easy to install and disassemble.

[0021] 2. In the cable support mechanism for fiber composite jacking pipe and the use method thereof, by installing the mounting plate on the connecting plate, the mounting column can slide up and down in the mounting groove, and the mounting column is limited by the buffer spring. When the suspension frame slides onto the hollow bracket, the buffer spring is compressed by its own gravity and the gravity of the cable, which will give the suspension frame an upward elastic force, thereby increasing the load-bearing capacity of the suspension frame and facilitating the storage of more cables. At the same time, when the limit block is ejected into the limit groove, the limit block will give the suspension frame a downward pressure, thereby achieving the dynamic balance of the suspension frame. When the fiber composite jacking pipe is vibrated during work, the suspension frame can be buffered to a certain extent. Therefore, the present invention has high reliability and good load-bearing capacity.

[0022] 3. In the cable support mechanism for fiber composite jacking pipe and the use method thereof, a sliding rod is arranged in the hollow bracket. When the suspension frame moves and pushes the cylindrical block to move, the reset spring moves to the fixed block and compresses, generating a leftward thrust on the suspension frame, and at the same time, the limit block abuts against the limit groove, thereby realizing horizontal limit of the suspension frame. When the limit spring fails, the suspension frame can still realize horizontal limit through the limit block and the cylindrical block. Therefore, the structure of the present invention is stable and highly reliable. BRIEF DESCRIPTION OF THE DRAWINGS
