Description

Technical Field

[0001] The present application relates to the field of electric power facilities, and in particular to a dual-material clamp for fixing guide rails. Background Art

[0002] In the power industry, power towers are crucial transmission facilities, and their stability and safety are paramount. Installing rails on towers to support equipment or provide maintenance access is a common engineering requirement. However, traditional rail attachment methods typically require machining mounting or fixing holes in angle steel, then securing the rails to the angle steel with bolts and other fasteners. This not only increases installation costs, but drilling holes in the angle steel also compromises its structural integrity, reducing its strength and potentially posing safety risks. Therefore, it is necessary to address these technical issues. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a dual-material clamp for fixing a guide rail, so as to solve the technical problem of high cost of installing and fixing the guide rail in the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted in this application is to provide a dual-material clamp for fixing a guide rail, comprising:

[0005] Support members;

[0006] A clamping member, flatly attached to the support member;

[0007] A cross arm screw, forming a tapered flange and a threaded section passing through the clamping member, wherein the tapered surface of the tapered flange is flat against a side of the support member facing away from the clamping member;

[0008] a nut, threadedly connected to the threaded section and capable of clamping the support member between the clamping member and the tapered flange;

[0009] The guide rail is connected to the cross arm screw.

[0010] Optionally, the cross arm screw is formed with two tapered flanges and two threaded sections spaced apart from each other, and the cross arm screw further comprises a polished rod section connected between the tapered flanges;

[0011] The support member and the clamping member are bent correspondingly and each forms an angle corresponding to the polished rod segment. The two sides of the support member used to form the angle are clamped correspondingly by the two sides of the clamping member used to form the angle and the two conical flanges.

[0012] Optionally, the cross arm screw is bent between the conical flange and the threaded section so that the axial direction of the threaded section is perpendicular to the clamping member.

[0013] Optionally, two support members are provided at intervals and with angles facing opposite directions, and the dual-material clamp for fixing the guide rail further comprises a cross connecting member provided between the support members and used to connect the two support members;

[0014] The clamping member passes through the spaces between the supporting members.

[0015] Optionally, the clamping parts, the cross arm screws and the nuts are arranged in multiple groups at intervals along the extension direction of the guide rail.

[0016] Optionally, the dual-material clamp for fixing the guide rail further comprises a connecting plate connected to the guide rail, a clamping plate spaced apart from the connecting plate, and a fastener connected between the clamping plate and the connecting plate;

[0017] The polished rod segment is clamped between the clamping plate and the connecting plate.

[0018] Optionally, an arcuate groove adapted to the diameter of the polished rod segment is provided on the clamping plate, and the depth direction of the arcuate groove is perpendicular to the extension direction of the guide rail.

[0019] Optionally, a plurality of arc-shaped grooves are provided and the arrangement direction is parallel to the extension direction of the guide rail.

[0020] The beneficial effect of the dual-material clamp for fixing the guide rail provided by the present application is that, compared with the prior art, in the dual-material clamp for fixing the guide rail of the present application, the conical surfaces of the conical flanges on the clamping piece and the cross-arm screw are respectively flat on opposite sides of the support member, and by adjusting the nut threadedly connected to the threaded section on the cross-arm screw, the support member can be clamped between the conical flange and the clamping piece, and the guide rail connected to the cross-arm screw can be installed and fixed. Since the conical surface of the conical flange and the clamping piece are both flat on the support member, this not only allows the support member to be tightly clamped while its structural integrity is not destroyed, but also effectively avoids the operation of drilling holes in the support member. Therefore, the dual-material clamp for fixing the guide rail in the present application can significantly reduce the installation and fixing costs of the guide rail, which is far superior to the prior art.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0031] Please also refer to Figures 1 to 4The following describes a dual-material clamp for fixing a guide rail provided in an embodiment of the present application. The dual-material clamp for fixing a guide rail includes a support member 101, a clamping member 102, a crossbar screw 103, a nut 104, and a guide rail 105.

[0032] The clamping member 102 is flat against the support member 101; the cross arm screw 103 forms a tapered flange 131 and a threaded section 132 that passes through the clamping member 102, and the tapered surface of the tapered flange 131 is flat against the side of the support member 101 facing away from the clamping member 102; the nut 104 is threadedly connected to the threaded section 132 and can clamp the support member 101 between the clamping member 102 and the tapered flange 131; the guide rail 105 is connected to the cross arm screw 103. In this embodiment, the guide rail 105 can be a T-shaped guide rail 105 or an I-shaped guide rail 105 commonly used in the field, which is used to install a fall arrester and guide the travel process of the fall arrester. For ease of explanation, this embodiment uses the guide rail 105 as an example of a T-shaped guide rail 105.

[0033] According to the above structure provided in this embodiment, in the dual-material clamp for fixing the guide rail, the conical surfaces of the clamping member 102 and the conical flange 131 on the crossarm screw 103 are respectively flatly attached to opposite sides of the support member 101. By adjusting the nut 104 threadedly connected to the threaded section 132 of the crossarm screw 103, the support member 101 can be clamped between the conical flange 131 and the clamping member 102, and the guide rail 105 connected to the crossarm screw 103 can be installed and fixed. Because the conical surface of the conical flange 131 and the clamping member 102 are both flatly attached to the support member 101, this not only ensures that the support member 101 is tightly clamped while maintaining its structural integrity, but also effectively avoids the need to drill holes in the support member 101. It is understood that the support member 101 here can be a longitudinal support angle steel in the triangular steel frame of the power tower, arranged in a back-to-back structure and connected by a cross connector 106 (described later) to enhance the stability and support strength of the power tower. Therefore, the dual-material clamp for fixing the guide rail in this embodiment can significantly reduce the installation and fixing cost of the guide rail 105, which is far superior to the existing technology.

[0034] In another embodiment of this application, please refer to Figures 1 to 4The cross arm screw 103 is formed with two tapered flanges 131 and two threaded sections 132 spaced apart from each other. The cross arm screw 103 also includes a polished rod section 133 connected between the tapered flanges 131. The support member 101 and the clamping member 102 are bent correspondingly and each forms an angle directly opposite the polished rod section 133. The two sides of the support member 101 used to form the angle are clamped by the two sides of the clamping member 102 used to form the angle and the two tapered flanges 131. According to the above structure provided in this embodiment, the cross arm screw 103, by providing the two tapered flanges 131 and the two threaded sections 132, can cooperate with the two sides of the clamping member 102 used to form the angle to clamp the support member 101 at two locations. This allows the dual-material clamp for fixing the guide rail in this embodiment to achieve a more stable guide rail 105 fixation effect. In addition, in this embodiment, the support member 101 and the clamping member 102 can directly use angle steel commonly used in the field (ie, longitudinal angle steel used to form power towers), which can further reduce the installation and fixing cost of the guide rail 105.

[0035] In another embodiment of this application, please refer to Figures 1 to 4 The cross arm screw 103 is bent between the tapered flange 131 and the threaded section 132 so that the axial direction of the threaded section 132 is perpendicular to the clamping member 102. According to the structure provided in this embodiment, since the bend formed between the tapered flange 131 and the threaded section 132 allows the axial direction of the threaded section 132 to be perpendicular to the clamping plate, during the adjustment of the nut 104, the pressure exerted by the nut 104 on the clamping plate can act perpendicularly on the clamping plate, thereby effectively improving the load capacity of the clamping plate and preventing deformation, thereby further reducing the installation and fixing costs of the guide rail 105.

[0036] In another embodiment of this application, please refer to Figures 1 to 4 Two support members 101 are spaced apart and oriented at opposite angles. The dual-material clamp for securing the guide rail further includes a cross connector 106 disposed between the support members 101 and used to connect the two support members 101. The clip 102 passes through the gap between the support members 101. According to the structure provided in this embodiment, connecting the two support members 101 via the cross connector 106 significantly improves the installation stability of the guide rail 105.

[0037] In another embodiment of this application, please refer to Figures 1 to 4 Multiple groups of the clips 102, cross arm screws 103, and nuts 104 are arranged at intervals along the extension direction of the guide rail 105. According to the above structure provided in this embodiment, the multiple groups of the clips 102, cross arm screws 103, and nuts 104 arranged along the extension direction of the guide rail 105 can further improve the installation stability of the guide rail 105.

[0038] In another embodiment of this application, please refer to Figures 1 to 4 The dual-material clamp for fixing the guide rail further includes a connecting plate 107 connected to the guide rail 105, a clamping plate 108 spaced apart from the connecting plate 107, and a fastener 109 connected between the clamping plate 108 and the connecting plate 107; the polished rod section 133 is clamped between the clamping plate 108 and the connecting plate 107. According to the above structure provided in this embodiment, the fastener 109 connected between the connecting plate 107 and the clamping plate 108 can stably clamp the polished rod section 133 of the crossarm screw 103 between the clamping plate 108 and the connecting plate 107, so that the guide rail 105 can be stably connected to the crossarm screw 103, which is conducive to further reducing the installation and fixing cost of the guide rail 105. The fastener 109 described in this embodiment can be a bolt and nut 104 combination commonly used in the art.

[0039] In another embodiment of this application, please refer to Figures 1 to 4 The clamping plate 108 is provided with an arcuate groove 181 adapted to the diameter of the polished rod segment 133, and the depth direction of the arcuate groove 181 is perpendicular to the extension direction of the guide rail 105. According to the above structure provided in this embodiment, since the depth direction of the arcuate groove 181 provided on the clamping plate 108 is perpendicular to the extension direction of the guide rail 105, when the cross-arm screw 103 is adapted to the arcuate groove 181 and the polished rod segment 133 is located in the arcuate groove 181 and is clamped by the clamping plate 108 and the connecting plate 107, it can be more stably clamped between the clamping plate 108 and the connecting plate 107, which helps to further improve the installation stability of the guide rail 105.

[0040] In another embodiment of this application, please refer to Figures 1 to 4 , multiple arc-shaped grooves 181 are provided and arranged in a direction parallel to the extension direction of the guide rail 105. According to the above structure provided in this embodiment, since the support plates are connected by the cross connector 106, in an embodiment provided with multiple sets of clamping members 102, cross arm screws 103 and nuts 104, the cross arm screws 103 can be clamped in different arc-shaped grooves 181 so that the clamping members 102 avoid the cross connector 106 and the cross arm screws 103 can be more evenly distributed along the extension direction of the guide rail 105. This helps to better prevent deformation of the guide rail 105 and further improve the installation stability of the guide rail 105.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
