[0026] See also Figure 1-Figure 4The present embodiment provides a sleeper spike anchoring construction fixing and positioning device, including a soft rail body 2 and a sleeper spike 3. A reserved spike anchoring hole 21 is provided on the top of the soft rail body 2. Two sleeper spike anchoring holes 22 are symmetrically provided at the bottom of the reserved spike anchoring hole 21. The sleeper spike 3 is used to be inserted into the sleeper spike anchoring hole 22. The soft rail body 2 and the sleeper spike 3 are prior art and will not be described in detail herein. The fixing and positioning device body 1 is also provided. The fixing and positioning device body 1 includes an anchoring bracket 11. The size of the anchoring bracket 11 is adapted to the size of the reserved spike anchoring hole 21. Connecting plates 12 are symmetrically connected to both sides of the anchoring bracket 11. The ends of the two connecting plates 12 away from the anchoring bracket 11 are fixedly connected to a spike positioning sleeve 13. The spike positioning sleeve 13 corresponds to the position of the sleeper spike anchoring hole 22. The sleeper spike 3 is positioned and placed In the spike positioning sleeve 13, a fixing piece 14 is arranged in the spike positioning sleeve 13, and the fixing piece 14 is used to fix the position of the sleeper spike 3 and the spike positioning sleeve 13. When in use, the sleeper spike 3 is placed in the spike positioning sleeve 13, and the fixing piece 14 is used to fix the position of the sleeper spike 3, so that the anchoring part of the sleeper spike 3 faces downward, and then an anchoring agent is injected into the sleeper spike anchoring hole 22 to be operated, and then the anchoring bracket 11 is vertically downward installed into the reserved spike anchoring cavity 21, so that the sleeper spike 3 in the spike positioning sleeve 13 is pressed correspondingly to the sleeper spike anchoring hole 22, so that the sleeper spike 3 is inserted into the sleeper spike anchoring hole 22 in alignment, and the fixing and positioning device body 1 is removed after curing, so that the sleeper spike 3 on the sleeper can be completely installed at one time, and the precision is greatly improved compared with the manual installation of the sleeper spikes 3 separately, the error is reduced, and the accuracy is improved.

[0027] In this embodiment, if Figure 1 As shown, an opening is provided on one side of the spike positioning sleeve 13 for the sleeper spike 3 to pass through, and the other end of the spike positioning sleeve 13 is set as an arc-shaped structure. The width of the spike positioning sleeve 13 is adapted to the diameter of the sleeper spike 3, and the cross-section of the spike positioning sleeve 13 is a U-shaped structure. When placing the sleeper spike 3, the sleeper spike 3 is placed in the spike positioning sleeve 13 from the opening of the spike positioning sleeve 13 and abuts against the inner wall of the arc end of the spike positioning sleeve 13. By adapting the width of the spike positioning sleeve 13 to the diameter of the sleeper spike 3, the sleeper spike 3 is initially limited to avoid the position deflection of the sleeper spike 3 and ensure that the sleeper spike 3 is in a vertical state.

The end of the fixing member 14 does not protrude from the inner wall of the spike positioning sleeve 13. The fixing member 14 is a strong magnet, which is used to adsorb and fix the sleeper spike 3. When the sleeper spike 3 is placed in the spike positioning sleeve 13, the fixing member 14 with a strong magnet can adsorb and fix the sleeper spike 3, thereby fixing the position of the sleeper spike 3. Moreover, the end of the fixing member 14 does not protrude from the inner wall of the spike positioning sleeve 13, so as to avoid interference and obstruction of the sleeper spike 3 by the fixing member 14.

[0029] In this embodiment, if Figure 1 and Figure 2 As shown, the anchor bracket 11 is welded by two transverse bars and two longitudinal bars, and two connecting plates 12 are respectively fixedly connected to two parallel longitudinal bars. The two transverse bars and two longitudinal bars are welded to each other to form the anchor bracket 11, and the connecting plates 12 are welded and fixed to the two longitudinal bars.

[0030] In this embodiment, if Figure 1 and Figure 2 As shown, the connecting plate 12 is inclined, and the height of the bottom end of the spike positioning sleeve 13 is higher than the height of the anchor bracket 11, so that when the sleeper spike 3 in the spike positioning sleeve 13 is inserted into the sleeper spike anchor hole 22 for fixing, it avoids contact with the anchoring agent in the sleeper spike anchor hole 22, which facilitates the removal of the fixing and positioning device body 1 from the soft rail body 2 at a later time.

[0031] In this embodiment, if Figure 1 and Figure 2 As shown, a reinforcement rod 15 is fixedly connected between the two road spike positioning sleeves 13 , and the stability between the two road spike positioning sleeves 13 is improved by the provided reinforcement rod 15 .

[0032] In this embodiment, if Figure 1 and Figure 2 As shown, the bottom of one of the crossbars is fixedly connected with a limit plate 16, and the limit plate 16 is tilted, and the tilt angle is adapted to the side wall of the soft rail body 2. When the anchor bracket 11 is placed in the reserved spike anchor hole 21, the limit plate 16 is tightly attached to one side of the soft rail body 2, which is used to limit the position of the anchor bracket 11, and further improve the installation and positioning accuracy of the sleeper spike 3 in the spike positioning sleeve 13.

[0033] Working principle: When in use, the sleeper spike 3 is placed in the spike positioning sleeve 13, and the fixing member 14 is used to adsorb and fix the sleeper spike 3 so that the anchoring part of the sleeper spike 3 faces downward, and then the anchoring agent is injected into the sleeper spike anchor hole 22 to be operated, and then the anchoring bracket 11 is vertically installed downward into the reserved spike anchoring cavity 21, and the limiting plate 16 is tightly attached to one side of the soft rail body 2, so that the sleeper spike 3 in the spike positioning sleeve 13 and the sleeper spike anchor hole 22 are pressed correspondingly, so that the sleeper spike 3 is inserted into the sleeper spike anchor hole 22 in alignment, and the fixing and positioning device body 1 is removed after curing, so that the sleeper spike 3 on the sleeper can be completely installed at one time. Compared with the manual installation of the sleeper spikes 3 separately, the precision is greatly improved, the error is reduced, and the accuracy is improved. In addition, the structure is simple, the materials are easy to obtain, the manufacturing cost is low, and the practicability is high.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
