Description

Technical Field

[0001] The utility model belongs to the technical field of connection devices, and in particular relates to a connection plate for installing a falling guide rail, the falling guide rail and a transmission line angle steel tower. Background Art

[0002] According to relevant technical regulations, steel pipe towers, towers with a nominal height of more than 30m, and towers for newly built lines of 220kV and above should be equipped with anti-fall devices for tower operations, and mandatory regulations are made on the form and size of the guide rails; the anti-fall device for tower operations stipulates that the curvature of a single rigid guide rail shall not exceed L / 1000 and should be less than 4m, the self-locking device shall not be separated from the guide rail when in use and shall only slide along the guide rail direction, the matching clearance with the guide rail shall be less than 2mm, and the distance between the outer plane of the vertical guide rail of the tower body and the toe back or toe tip of the angle steel is 100mm. In the relevant regulations on anti-fall devices for newly built line tower operations, the size of the guide rail and the opening diameter and position of the connecting plate are also stipulated; one end of the connecting plate is connected to the screw hole of the guide rail, and the other end is connected to the foot nail of the angle steel tower leg.

[0003] Taking into account the matching adjustment during installation, the guide rail end opening of the connecting plate is generally a horizontal long hole, and the tower material end is a vertical long hole; in actual installation, due to the improper installation of the connecting plate between the guide rail and the tower body, the adjustment of the long hole at the tower material end of the connecting plate is inconsistent during installation, resulting in the guide rail and the tower body parallel surface becoming wavy or the two guide rail joints having misaligned mouths, making it difficult to meet the standard requirement of 100mm distance between the outer plane of the vertical guide rail of the tower body and the toe back or toe tip of the angle steel, which will cause the self-locking device to not slide smoothly in later use, resulting in the guide rail being stuck and unable to be safely protected.

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] Embodiment 1:

[0030] like Figure 1 As shown, when the guide rail 2 is installed with the traditional connector 1, the connector 1 between the guide rail 2 and the tower body is not installed in a standardized manner, and the long hole at the tower material end of the connector 1 is not adjusted consistently during installation, resulting in the guide rail 2 and the parallel surface of the tower body being wavy or the joints of the two guide rails 2 being misaligned, making it difficult to meet the standard requirement that the distance between the outer plane of the vertical guide rail 2 of the tower body and the toe back or toe tip of the angle steel 3 is 100 mm, which will cause the self-locking device to not slide smoothly during later use, thereby causing the guide rail to become stuck and unable to be safely protected.

[0031] Based on this, Figure 2 As shown, this embodiment provides a connector 1 for installing a fall rail, comprising a first connecting plate 102 and a second connecting plate 104 welded to each other or integrally formed;

[0032] The first connecting plate 102 is provided with a first long hole 101 , and the second connecting plate 104 is provided with a second long hole 103 ; a limiting member 105 is provided at an end of the second connecting plate 104 away from the first connecting plate 102 .

[0033] A limit piece 105 is provided at the end of the connection between the connector 1 and the angle steel tower material; when connected, the limit piece 105 is in close contact with the three sides of the angle steel, thereby limiting the length of the connector 1 extending beyond the toe of the angle steel 3, ensuring that it meets the standard requirement that the distance between the outer plane of the tower body vertical guide rail 2 and the toe or toe tip of the angle steel 3 is 100 mm.

[0034] Optional, such as Figure 1 and Figure 2 As shown, the first long hole 101 and the second long hole 103 are elliptical holes, which are convenient for installing the bolt 5 and the foot nail 4.

[0035] Specifically, the long axis of the first long hole 101 is perpendicular to the length direction of the connector 1, and the long axis of the second long hole 103 is perpendicular to the long axis of the first long hole 101. The first connecting plate 102 and the second connecting plate 104 are arranged at a preset angle to facilitate the connection between the guide rail 2 and the angle steel 3.

[0036] like Figure 2 As shown, the stopper 105 is a stopper plate perpendicular to the second connecting plate 104. On the basis of the conventional connecting member 1, the second connecting plate 104 can be extended to provide the stopper 105. The second connecting plate 104 and the stopper 105 are T-shaped structures.

[0037] like Figure 5 As shown, in some embodiments, the second connecting plate 104 and the limiting member 105 are inverted L-shaped structures, which reduce the material consumption compared to the limiting member 105 of the T-shaped structure and avoid the interference of the extended part at the other end of the T-shaped structure with the installation operation.

[0038] like Figure 3 As shown, the guide rail 2 includes a guide rail body 201 and a guide rail screw hole 202 arranged on the guide rail body 201. Figure 2 As shown, the angle steel 3 includes a first steel plate 301 and a second steel plate 302 which are perpendicular to each other, and an angle steel connecting hole 303 opened on the second steel plate 302 .

[0039] During installation, the guide rail screw hole 202 and the first long hole 101 are connected together by bolts 5, so that the guide rail 2 is connected to one end of the connecting member 1. The second long hole 103 and the angle steel connecting hole 303 are connected by foot nails 4, so that the angle steel 3 is connected to the other end of the connecting member 1.

[0040] When installing the anti-fall guide rail, on-site workers cannot adjust the long opening of the connecting plate connected to the tower material well, and cannot meet the requirement that the distance between the outer plane of the vertical guide rail of the tower body and the toe back or toe tip of the angle steel is 100mm. Through the connecting piece 1 in this embodiment, only one end of the limit piece 105 needs to be brought close, which is easy to install and easy to improve the installation quality. During the project acceptance, only the closeness of the end of the limit piece 105 needs to be checked and supervised, which is easy for project acceptance, improves the project quality, and provides high-quality safety protection for workers who perform high-altitude operations.

[0041] Embodiment 2:

[0042] This embodiment provides a fall guide rail, including a guide rail body 201 , on which a connector 1 for installing the fall guide rail as described in Embodiment 1 is provided through a guide rail screw hole 202 .

[0043] Optionally, the guide rail screw hole 202 and the first long hole 101 are connected by a bolt 5 .

[0044] Embodiment 3:

[0045] This embodiment provides a transmission line angle steel tower, comprising a first steel plate 301 and a second steel plate 302 perpendicular to each other, and a connector 1 for installing a falling guide rail as described in Example 1 is provided on the second steel plate 302 through foot nails 4.

[0046] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
