[0005] Furthermore, the pull rod includes a sleeve and a screw; threads are engraved in the two side pipe openings of the sleeve, and the threads in the two side pipe openings have opposite rotation directions. The two screws are respectively screwed with the two side pipe opening threads of the sleeve, and the ends of the two screws are fixedly connected to the baffle.
[0006] Furthermore, the pull rod also includes a locking nut, which is screwed with the thread of the screw rod.
[0007] Furthermore, the sleeve is coated with reflective material.

[0016] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown: a construction tool for controlling the track gauge of a turnout and protecting a point rail, comprising a retractable pull rod 1, with baffles 2 installed at both ends of the pull rod 1, and the two ends of the pull rod 1 are connected to the point rail 3 through the baffles 2; the direction parallel to the baffle 2 and the point rail 3 is the length direction, the middle of the baffle 2 in the length direction is connected to the pull rod 1, and the through holes 2.1 on both sides of the pull rod 1 on the baffle 2 are connected to the reserved holes 3.1 for the switch machine on the point rail 3 through bolts 4.
[0018] The length adjustment range of the pull rod 1 is 1200-1350mm. The pull rod 1 includes a sleeve 1.1 and a screw 1.2. The sleeve 1.1 has threads engraved in the two side openings. The threads in the two side openings are rotated in opposite directions. The two screws 1.2 are respectively screwed with the threads of the two side openings of the sleeve 1.1. The ends of the two screws 1.2 are fixedly connected to the baffle 2. The two screws 1.2 are stationary. When the sleeve 1.1 is rotated, the two screws 1.2 are extended or retracted from the sleeve 1.1 at the same time, and the total length of the pull rod 1 is increased or shortened.
[0019] The pull rod 1 also includes a lock nut 1.3. Each screw rod 1.2 has two lock nuts 1.3. The lock nuts 1.3 are screwed together with the screw rod 1.2. After the pull rod 1 is adjusted to the target length, the two lock nuts 1.3 are rotated toward the sleeve 1.1, and the two lock nuts 1.3 press the sleeve 1.1 tightly.
[0020] The sleeve 1.1 is coated with a reflective material 5 for nighttime warning.
[0021] The through hole 2.1 on the baffle plate 2 is a long hole parallel to the length direction of the baffle plate 2. The hole spacing x between the two through holes 2.1 on the baffle plate 2 is 118 mm, and the eccentric hole spacing x is 123 mm.
[0022] The installation and disassembly process of a construction tool for controlling the track gauge of a turnout and protecting the point rail is as follows: After the turnout is pre-laid, confirm the installation position of the switch machine and the self-locking connecting rod. Measure the spacing size with a track ruler, and apply anti-rust grease on the screw 1.2 of the tie rod 1. Adjust the tie rod 1 to the appropriate length by rotating the sleeve 1.1. Install the baffles 2 at both ends of the tie rod 1 on the point rail 3 by bolts 4. Tighten the anti-loosening nut 1.3 on the screw 1.2. After the electrification professional intervenes, first loosen the anti-loosening nut 1.3, and then remove the baffle 2. Confirm the quantity and parts of the removed components. Apply oil to the entire tool to prevent rust, and then wrap it in newspaper for storage.
