[0014] The preferred embodiment of the utility model is described in detail below in combination with the drawings.
[0015] As Figure 1 A track gauge and track bottom slope double control tool shown in the figure, for the track gauge and track bottom slope adjustment of the steel rail 2 arranged on the tool frame 1, the control tool includes a group of slope iron pads 3, two groups of reinforcing clamps 4 and two groups of fixing devices symmetrically arranged at both ends of the tool frame 1;The slope iron pad 3 is arranged between the tool frame 1 and the steel rail 2, the upper end face of the slope iron pad 3 is provided with a rail groove 31 for placing the steel rail and a sawtooth protrusion 32 evenly distributed on both sides of the rail groove 31, and the slope of the inner bottom surface of the rail groove 31 is 1:40.
[0016] As Figure 2 Described in the preferred embodiment, the inner bottom surface of the rail groove 31 is set to 1:40 standard slope, after the installation of the double control tool described in the utility model, the base of the steel rail 2 can be completely fitted with the inner bottom surface of the rail groove 31, so that it reaches the 1:40 standard track bottom slope required by the specification;At the same time, after the concrete pouring, the slope can be guaranteed between 1:35-1:45, the track bottom slope error is extremely small, and it completely meets the allowable deviation range of the specification.
[0017] At the same time, the two sides of the rail groove 31 described in the preferred embodiment are provided with limit protrusions, which can avoid the offset of the steel rail 2 on the rail groove 31 after the installation of the double control tool described in the utility model.
[0018] AsFigure 3 As shown, the reinforcing calipers 4 of the preferred embodiment are arranged on both sides of the steel rail 2, and the lower end surface of the reinforcing calipers 4 is provided with a stepped groove 41 matched with the base of the steel rail 2 and a sawtooth-shaped groove 42 matched with the sawtooth-shaped protrusion 32 on the slope iron pad 3. The sawtooth-shaped protrusion 32 and the sawtooth-shaped groove 42 can make the contact part of the slope iron pad 3 and the reinforcing calipers 4 fit more closely, and can avoid the deviation between the slope iron pad 3 and the reinforcing calipers 4 after the installation of the double control tooling of the utility model is completed, thereby making the fixation of the tooling as a whole and the steel rail 2 more firm.
[0019] The fixing device of the preferred embodiment includes a nut 5 fixedly arranged on the lower end surface of the tooling frame 1 and a bolt 6 matched with the nut 5.
