[0001] The utility model relates to a sleeper steel mold, in particular to a sleeper steel mold positioning system and a steel mold containing the positioning system, belonging to the technical field of concrete sleeper manufacturing. Background Art

[0002] The sleepers support the rails and keep them stable. Therefore, in the construction of railway tracks, it is necessary to anchor the spikes to fix the rails on the sleepers so that the rails and sleepers are connected as a whole. At present, when sleepers are made, reserved holes for anchoring the spikes are reserved first. After the sleepers are made, most of them are manually anchored after the sleepers are laid on the line. Some are also manually anchored at special sites in the production base. In both methods, the anchoring material is poured into the reserved holes of the sleepers first, and then the locator is used to insert the spikes into the reserved holes. After the anchoring material solidifies, the locator is removed to complete the spike anchoring construction. Both of the above methods are manually operated and inefficient, which affects the progress of railway line laying.

[0003] Therefore, in order to improve the efficiency of spike anchoring and ensure the speed of railway line laying, a new method for producing concrete sleepers is proposed, that is, the spikes are anchored first and then the sleepers are made. The sleepers made by this method directly anchor the spikes, and the rails can be directly installed after the sleepers are laid, laying the foundation for speeding up the speed of railway track laying.

[0004] The production of sleepers requires a sleeper steel mold. In order to reserve the reserved holes required for anchoring the spikes on the sleepers, the existing steel molds need to be installed with sleeves. Obviously, the above steel molds are not suitable for the new production method of anchoring the spikes first and then producing the sleepers. Therefore, there is an urgent need for a steel mold suitable for the above-mentioned spike-first anchoring method to produce concrete sleepers. Utility Model Content
