[0002] As an active refrigeration device for gas-liquid two-phase conversion, the heat rod plays an active role in the thermal stability maintenance of the roadbed and bridge foundation in the permafrost area of ​​the Qinghai-Tibet Railway. The construction of the Golmud section of the Qinghai-Tibet Railway has been going on for 21 years since 2002. More than 40,000 heat rods have been buried in the permafrost area, and the longest service life of the heat rods has reached or exceeded 17 years. During long-term operation, some heat rods will inevitably fail. In this case, the heat rods buried in the roadbed need to be repaired and replaced on-site. The scientific researchers of China Railway Northwest Institute have carried out a lot of scientific research work and achieved fruitful research results. The repair and replacement plan is as follows: a solar generator can be installed at the end of the heat rod on site, and an appropriate amount of refrigerant can be added on-site through the reserved gas valve to control the filling amount so that it can start working under a low temperature difference. The non-working heat rods are headed, and then small multi-stage heat rods or solar heat rods are implanted in the original empty tubes of the heat rods buried underground. In order to ensure smooth and convenient repair and replacement, auxiliary devices for implanting small multi-stage heat rods or solar heat rods in the empty tubes of the heat rods are required to assist in improving the convenience of construction.

[0003] When implanting a small multi-stage heat rod or a solar heat rod in an empty heat rod tube, the small multi-stage heat rod needs to be inserted from top to bottom into the underground retention part of the failed heat rod, and the solar heat rod needs to be installed on the top of the heat rod. The length and height are greater than the length and height for convenient construction by construction workers, and it is inconvenient for construction workers to hold and limit the newly installed part.

The upper end of the arc clamp 3 is threadedly connected with a reverse threaded screw 20, and the right end of the reverse threaded screw 20 is fixedly mounted with a micro servo motor 19.
