The utility model discloses a fixing device for anchoring sleeper spikes, which relates to the technical field of sleeper spike construction and comprises handles, the handles are symmetrically arranged on one sides of bases, limiting mechanisms are arranged on the outer sides of the bases, and the limiting mechanisms are used for adjusting the distance between the two symmetrically arranged bases according to the width of a track. And a positioning mechanism is arranged under the base, the positioning mechanism clamps the two sides of the track, then positioning treatment is conducted on the bottom end of the base, and the situation that the track spikes shake in the curing process is avoided. The distance between the two sets of bases is adjusted, then bolts are inserted into fastening holes, and transverse connecting rods and the bases are locked, so that transverse unfolding and storage of the bases are facilitated, the space needed by the device in the using process is saved, after anchoring is completed and the strength is achieved, an anti-pulling instrument is adopted for detecting the anti-pulling force, and the detection efficiency is improved. The anti-pulling force is not less than 60KN, which is tested on site.
