DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the embodiment of the utility model is explained in detail below, but the embodiment described in the utility model is a part of the embodiment of the utility model, not all the embodiment.

[0022] As Figures 1-5 The embodiment provides a railway roadbed protective fence stand positioning tool, which comprises pull rod assemblies 10 arranged in a triangular shape on the outer periphery of the stand 1, and the pulling force of each pull rod assembly 10 on the stand 1 is the same, so that the stand 1 remains vertical.

[0023] Specifically, as shown in Figure 1, the tie rod assembly 10 includes a bidirectional adjusting component 11, an upper tie rod 12, a lower tie rod 13, a pull plate 14, and a locking anchor rod 15. The bidirectional adjusting component 11 has a rectangular frame structure, such as... Figure 5 As shown, the upper horizontal part of the bidirectional adjusting component 11 has an upper threaded hole 111 at its center, and the axis of the upper threaded hole 111 is consistent with the length direction of the bidirectional adjusting component 11. The lower horizontal part of the bidirectional adjusting component 11 has a lower threaded hole 112 at its center, corresponding to the upper threaded hole 111, and the rotation direction of the upper threaded hole 111 is opposite to that of the lower threaded hole 112. The upper pull rod 12 and the lower pull rod 13 are respectively located at both ends of the bidirectional adjusting component 11. The lower end of the upper pull rod 12 has a first threaded section 121, and the upper end of the lower pull rod 13 has a second threaded section 131. The first threaded section 121 is threadedly connected to the upper threaded hole 111, and the second threaded section 131 is threadedly connected to the lower threaded hole 112.

[0024] like Figure 2 , Figure 5 As shown, the pull plate 14 is rotatably mounted on the upper end of the upper pull rod 12. The pull plate 14 includes a first inclined plate 141, a connecting pin 142, a second inclined plate 143, and a locking rod 144. The lower end of the first inclined plate 141 is inclined downward to the right. The lower end of the second inclined plate 143 is connected to the lower end of the first inclined plate 141. The upper end of the second inclined plate 143 is inclined upward to the right, and the length of the second inclined plate 143 is greater than the length of the first inclined plate 141. The connecting pin 142 is vertically mounted on the upper end of the inner side of the first inclined plate 142. The locking rod 144 is respectively mounted on both ends of the inner side of the second inclined plate 143 for locking the opposite sides of the column 1.

[0025] like Figure 3 As shown, the locking anchor rod 15 has an inverted L-shaped structure, with a spike at the lower end of its vertical part. The locking anchor rod 15 passes through the seat plate 151, and a triangular seat 152 is provided on the seat plate 151. A U-shaped seat 132 is provided at the lower end of the pull rod 13. The U-shaped seat 132 is rotatably connected to the triangular seat 152. In use, the bottom surface of the seat plate 151 is flush with the ground surface, and the vertical part of the locking anchor rod 15 is inserted into the ground along the top surface of one end of the seat plate 151. The horizontal part of the locking anchor rod 15 is then struck with a hammer to limit the seat plate 151.

[0026] The specific usage process is as follows:

[0027] The second inclined plate 143 of the pull plate 14 is attached to one face of the stand 1, and according to the width of the face of the stand 1 attached to the inner side of the second inclined plate 143, the spacing of the clamping rods 144 at both ends of the second inclined plate 143 in the vertical direction is consistent with the width of the face of the stand 1 attached to the inner side of the second inclined plate 143, so that the clamping rods 144 at both ends of the second inclined plate 143 are clamped to both sides of the stand 1, that is, the wider the width of the face of the stand 1 attached to the second inclined plate 143, the smaller the included angle between the second inclined plate 143 and the horizontal plane, and vice versa.

[0028] When the clamping rods 144 are clamped to both sides of the stand 1, the horizontal part of the locking foot anchor rod 15 will be outward, and the horizontal part of the locking foot anchor rod 15 is knocked downward to fix the position of the seat plate 151, and the bidirectional adjusting part 11 is rotated to keep the upper pull rod 12 and the lower pull rod 13 at both ends of the bidirectional adjusting part 11 taut, and the operation steps of the remaining two pull rod assemblies 10 are the same, and only need to ensure that the pulling force of the three pull rod assemblies 10 on the stand 1 is the same.

[0029] The above only describes the preferred embodiments of the present application, and does not mean that it is the only or limiting the present application. Those skilled in the art should understand that various changes or equivalent replacements made to the present application without departing from the scope of the present application, all belong to the scope of protection of the present application.
