Embodiment 1

[0032] see Figure 1-3 , a flattened cable pipe repair device, including a fixed seat 1, a support tube 2, a cover 3, a rotating rod 4, a repair head 5 and a rocking handle 6, the fixed seat 1 is arranged outside the cable pipe 7, and the One side of the fixed seat 1 is in contact with the port of the cable pipe 7, the upper end surface of the fixed seat 1 is I-shaped, and the middle part of the upper end surface of the fixed seat 1 is provided with a semicircular groove 8 matching the support tube 2, so that An anti-slip protrusion 11 is provided in the semicircular groove, and two radial jacking screws 9 are arranged on both sides of the fixing seat 1, and tooth plates 10 are provided at the ends of the jacking screws 9, and the The tooth plate 10 is in a concave arc shape, which is consistent with the arc shape of the outer wall of the support pipe 2 or the cable pipe 7. The tooth plate 10 is provided with tooth-shaped teeth facing the cable pipe or support pipe; the suppor...

Embodiment 2

[0039] The structure of the device for repairing the collapsed cable pipes in this implementation is the same as that of Embodiment 1, and will not be repeated.

[0040] see Figure 4 , when the flattened cable pipe repair device of the present invention is used, depressions appear on both sides of the cable pipe 7 at the same time (see Figure 4 ), so that the center line of the support tube 2 of the repair device coincides with the center line of the cable pipe 7, and at the same time make the cone 12 at the end of the repair head 5 of the repair device connected to the screw rod 4 close to the depression, and fix the fixing seat 1 and the jacking wire 9, so that one side of the fixing seat 1 is in contact with the port of the cable tube 7, the support tube 2 is placed in the semicircular groove 8, and the shaking handle 6 drives the rotation rod 4 and the repair head 5 to rotate and move in the direction of the depression , and gradually realize the repair.

Embodiment 3

[0046] The device and method of repairing the collapsed cable pipes in this implementation are the same in structure as in Embodiment 1, and will not be repeated.

[0047] Described cable pipe is made of the following raw materials in parts by weight:

[0048] 50 parts of EPDM rubber, 35 parts of SAN resin, 15 parts of glass fiber, 15 parts of polyhydroxyalkanoate, 6 parts of polyethylene wax, 15 parts of phenyl sulfonate, 20 parts of dioctyl phthalate , 7 parts of dicumyl peroxide and 3 parts of trimethylolpropane trimethacrylate.

[0049] The preparation method of described cable duct comprises the following steps:

[0050] Heat EPDM rubber and SAN resin in an internal mixer to 60°C, masticate for 4 minutes, then add glass fiber, polyhydroxyalkanoate, polyethylene wax, alkyl phenyl sulfonate and diphthalate Mix octyl esters, continue to stir for 6 minutes, finally add dicumyl peroxide and trimethylolpropane trimethacrylate, mix at 90 ° C for 4 minutes, and then send them i...

Abstract

The invention discloses a squashed cable duct repairing device. The squashed cable duct repairing device comprises a fixed seat, a support pipe, a seal cover, a rotary rod, a repairing head and a shaking handle. The fixed seat is arranged outside a cable duct. One side face of the fixed seat makes contact with a port of the cable duct. The upper end face of the fixed seat is in the shape of an I. The middle of the upper end face of the fixed seat is provided with a semicircular groove matched with the support pipe. The two sides of the fixed seat are each provided with two radial jacking wires. Tooth plates are arranged at the ends of the jacking wires correspondingly. The support pipe is located in the cable duct, and the center lines of the support pipe and the cable duct coincide. The seal cover is arranged at one end of the support pipe. The center of the seal cover is provided with a threaded hole. The rotary rod is provided with an outer thread matched with the threaded hole. The rotary rod penetrates through the seal cover and is coaxial with the support pipe. The shaking handle is arranged at the end, provided with the thread, of the rotary rod. The repairing head matched with the cable duct is arranged at the other end of the rotary rod. The squashed cable duct repairing device is simple in structure, simple, convenient and flexible to operate, deformation is not liable to occur to the cable duct, the impact resistance is good, and repairing is easy to be conduct after squashing.

Description

technical field [0001] The invention relates to a repair tool, in particular to a device for repairing flattened cable pipes. Background technique [0002] The cable pipe is a group of pipes buried in the ground in advance to pass through the cable. Laying the cables in the cable pipe can reduce the occurrence of cable faults, prolong the service life of the cable, and improve the reliability of the power supply of the power system. The current cable pipes are designed to avoid When the road is broken during construction, it is often built simultaneously with the municipal engineering, and the construction standard is relatively low. With the development of the city, when power construction is needed, many pipes are crushed due to the rolling of the road surface by the cart, resulting in Cables cannot be penetrated, resulting in waste of pipeline resources. Therefore, it is of great significance to study a kind of repairing device for crushed cable pipes. [0003] Chinese ...
