[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Details of specific structures or processes not specified in the embodiments are implemented with reference to relevant industry standards or conventional technical means.

[0021] Example 1: Basic Implementation

[0022] like Figure 1-4 As shown, the contact wire post positioning fixture in this embodiment includes a positioning component 1 and a mounting bracket 2. The positioning component 1 is integrally formed by cutting and bending a 10mm thick Q235 steel plate, and includes a fastening plate 11, a horizontal plate 12, a vertical plate 13, and a connecting plate 14. Wherein:

[0023] The fastening plate 11 and the horizontal plate 12 are located on the same horizontal plane, and the two are formed into a continuous plane by laser cutting;

[0024] The horizontal plate 12 and the vertical plate 13 are formed into an L-shape by a bending machine, and the height of the vertical plate 13 is 150mm;

[0025] The bottom of the upright plate 13 is bent to form a connecting plate 14. Two Φ12mm first mounting grooves 15 are opened on the connecting plate 14. The first mounting grooves 15 are long strips, which are convenient for fine-tuning the installation position.

[0026] Two sets of symmetrically distributed Φ40mm round holes are machined on the fastening plate 11. The hole spacing is set according to the design position of the contact wire column 5 (e.g., standard spacing 160mm).

[0027] Mounting bracket 2 is made of L80×8 angle steel. Two rows of Φ14mm second mounting slots 21 with a spacing of 200mm are opened on its side, and a third mounting slot 22 with a spacing matching the first mounting slot 15 is set on the top.

[0028] During installation:

[0029] Mounting bracket 2 is fixed to the side wall of the contact wire foundation fixture using M12 chemical anchors;

[0030] Using an M10×40 hex bolt 31, pass through the first mounting slot 15 and the third mounting slot 22, and lock it in place with the first washer 33, the second washer 34 and the nut 32 to achieve a detachable connection between the positioning component 1 and the mounting bracket 2;

[0031] After the pre-embedded steel plate 6 is positioned by binding with the supporting steel bar 4, the contact wire post 5 is inserted into the round hole of the fastening plate 11;

[0032] Tighten the second fastening screw 110 on the side of the mounting sleeve 18 so that the rubber head at the end of the screw presses against the side of the column 5 to achieve three-dimensional positioning.

[0033] Example 2: Dynamic Adjustment Implementation Method

[0034] like Figure 2 As shown, an adjustment mechanism is added based on Embodiment 1:

[0035] Two M16 first internal threaded posts 16 are welded to the top of the fastening plate 11, symmetrically distributed on both sides of the circular hole;

[0036] The first fastening screw 17 is an M16×100 fully threaded bolt with a 50mm×50mm×5mm nylon washer at the bottom;

[0037] After the pre-embedded steel plate 6 is initially positioned, the flatness of the steel plate is finely adjusted by screwing in the first fastening screw 17;

[0038] A 10mm thick reinforcing rib 23 is added to the middle of the mounting bracket 2 and fixed by welding with a triangular rib structure to improve vibration resistance.

[0039] Example 3: Composite Positioning Implementation Method

[0040] Combination Figure 3 This embodiment is for scenarios with multiple embedded parts:

[0041] Three sets of positioning devices are arranged at circumferential intervals of 500mm on the contact wire foundation jig;

[0042] The mounting sleeves of each set of devices have an inner diameter of 18mm and are configured according to the specifications of the pre-embedded bolts.

[0043] During concrete pouring, the levelness of the positioning component 1 is monitored in real time (by the level bubble on the mounting bracket 2), and dynamic compensation is performed by the first fastening screw 17 when a deviation is detected.

[0044] After demolding, loosen nut 32 to recycle the entire device, which can be reused more than 50 times.

[0045] Working principle: The rigid support frame is formed by combining the integrated positioning component 1 (including fastening plate 11, horizontal plate 12, vertical plate 13, and connecting plate 14) with the angle steel mounting frame 2, realizing the three-dimensional spatial positioning of the embedded parts; the embedded steel plate 6 is finely adjusted (accuracy ±0.5mm) by the cooperation of the first internal threaded column 16 and the first fastening screw 17; the contact wire column 5 is fixed by the second fastening screw 110 in the mounting sleeve 18; the design of the reinforcing rib 23 in the middle of the mounting frame 2 and the detachable fastening bolt 3 (including hexagonal bolt 31, nut 32, first washer 33, and second washer 34) enhances the resistance to displacement.

[0046] Implementation steps:

[0047] 1. Basic installation:

[0048] The angle steel mounting bracket 2 is fixed to the side wall of the contact wire foundation fixture by means of chemical anchors, bolts or welding.

[0049] Hex bolts 31 are passed through the first mounting slot 15 of the positioning assembly 1 and the third mounting slot 22 of the mounting bracket 2, and locked in place with the first washer 33 and the second washer 34.

[0050] 2. Positioning of embedded parts:

[0051] After the pre-embedded steel plate 6 is tied to the supporting steel bar 4, it is inserted into the round hole from the contact wire column 5 to the fastening plate 11.

[0052] Tighten the second fastening screw 110 on the side of the mounting sleeve 18 to press the side of the column 5 with the rubber head.

[0053] 3. Fine-tuning calibration:

[0054] Rotate the first fastening screw 17 to push the embedded steel plate 6 to adjust the flatness, and monitor the verticality through the level bubble on the mounting bracket 2.

[0055] 4. Recycling and turnover:

[0056] After demolding, loosen nut 32, separate positioning component 1 from mounting bracket 2, and recycle the entire device.
