Description

Technical Field

[0001] This utility model relates to the field of power line accessories technology, and in particular to a special clamp for angle steel towers used to fix line identification signs. Background Technology

[0002] Angle steel towers are the most widely used tower structures in high-voltage power transmission and transformation projects. In order to facilitate the inspection, maintenance and management of the lines, various signs such as line name signs, phase signs and warning signs are usually installed on the tower body of the angle steel tower. The main component for installing the signs is the fixing clamp, which reliably fixes the signs to the angle steel components of the tower body.

[0003] Currently, the traditional bolt-type fixing clamps are commonly used for installing signs on-site. These clamps are usually made of two or more metal plates, and the signs are clamped and fixed to the angle steel by passing bolts through and tightening nuts. However, this long-standing fixing method has revealed obvious shortcomings in practical applications.

[0004] Firstly, when designing and constructing angle steel towers, various specifications and thicknesses of angle steel materials are used depending on the different load-bearing requirements. However, traditional bolt-type clamps are usually fixed in size and lack adjustment capabilities, resulting in poor versatility. Installers often need to prepare multiple models of clamps for different specifications of angle steel, which not only increases the difficulty of spare parts management, but also seriously affects the installation progress if a model mismatch is found on site.

[0005] More importantly, the installation work on the angle steel tower is a high-altitude operation, which requires extremely high levels of convenience and safety. When using traditional clamps for installation, workers must carry a variety of tools such as wrenches to perform bolt alignment, insertion, and tightening operations in a high-altitude environment. This process is not only cumbersome and time-consuming, but also prone to tools or parts slipping and falling due to the limited working space and complex environmental factors, posing a serious safety hazard and greatly reducing the efficiency and safety of high-altitude operations.

[0006] Therefore, this utility model proposes a special clamp for angle steel towers used to fix line identification signs, in order to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of existing angle steel tower clamps used for fixing line signs, such as limited size, inability to adapt to different specifications of angle steel, reliance on tools during installation, and cumbersome and time-consuming high-altitude operations, this utility model aims to provide a fixing structure for angle steel tower clamps with improved structure that can effectively solve the above problems.

[0008] This utility model provides a fixing structure for a special clamp for fixing a line marker, comprising: a first angle steel, and a clamp installed on the first angle steel. The clamp includes an upper iron frame, a first fixing plate that slides with the upper iron frame, a lower iron frame, a second fixing plate that slides with the lower iron frame, and the marker to be fixed, as well as an adjustment component and a quick-release component for fixing the marker, which are disposed inside the upper iron frame.

[0009] The adjustment assembly includes a slide groove fixedly connected to the first fixed plate, a button slidably disposed on the side wall of the upper iron frame, a locking block fixedly connected to the lower surface of the button, a second fixing block fixed to the inner wall of the upper iron frame, and a spring disposed between the button and the second fixing block.

[0010] Furthermore, the upper iron frame and the first fixing plate are combined and locked together at the upper part of the first angle steel, and the lower iron frame and the second fixing plate are combined and locked together at the lower part of the first angle steel. The locking block and the sliding groove selectively engage to lock the position of the first fixing plate. The pin of the quick-release assembly passes through the sign, the upper iron frame and the lower iron frame in sequence, and is detachably locked by its latch.

[0011] Preferably, the inner wall of the upper iron frame is fixed with a slide rail, and the slide groove of the adjusting component is slidably disposed on the slide rail.

[0012] Preferably, the locking block of the adjustment component engages with the grooves at corresponding positions on both sides of the slide groove.

[0013] Preferably, the second fixing block of the adjusting assembly is fixed to the inner wall of the upper iron frame by a fixing wire.

[0014] Preferably, the quick-release assembly further includes a first fixing block, which is fixedly connected to one end of the pin.

[0015] Preferably, the pin of the quick-release assembly has a circular protrusion on the outer periphery of the end away from the first fixing block, and the latch has a reserved groove that cooperates with the circular protrusion. After the latch is sleeved on the pin and rotated, the circular protrusion is engaged in the reserved groove.

[0016] Preferably, the lower iron frame is also provided with the adjustment component for locking the position of the second fixing plate relative to the lower iron frame.

[0017] Preferably, the first angle steel is an L-shaped profile.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting a press-type adjustment component, allows the upper iron frame of the clamp to slide and be quickly locked with the first fixed plate, and the lower iron frame to be adjusted with the second fixed plate. This solves the problem that the clamp in the prior art has a single size and cannot adapt to angle steel of different specifications, and achieves the technical effect of strong versatility and wide applicability.

[0019] 2. This utility model replaces the traditional bolt fastening method by setting an adjustment component and a quick-release component that cooperates with a pin and a buckle. It solves the problems in the prior art that fixing signs requires tools, and that installation is time-consuming and poses safety hazards when working at height. It achieves the technical effects of tool-free installation, convenient operation, significantly shortening the time for working at height, and improving the safety of operation.

[0020] 3. This utility model solves the problems of complex fixing structures and cumbersome installation steps in the prior art by combining the sliding adjustment structure with the quick-release fixing structure, and achieves the technical effect of simple and compact overall structure, reliable locking, easy operation and widespread use.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 6 This utility model provides a fixing structure for a special clamp for fixing line identification signs on angle steel towers, aiming to solve the problems of fixed clamp size, inability to adapt to different specifications of angle steel, and strong dependence on tools during installation in the prior art.

[0025] like Figure 1 and Figure 2 As shown, the fixing structure includes a first angle steel 1, a clamp installed on the first angle steel 1, and a nameplate 4 to be fixed. The clamp is used to hold and fix the first angle steel 1 on the angle steel tower, and the nameplate 4 is fixed to the clamp by the quick-release assembly 5 of the clamp.

[0026] The main structure of the clamp includes an upper iron frame 2, a lower iron frame 6, a first fixing plate 3, and a second fixing plate 7. The upper iron frame 2 and the first fixing plate 3 are jointly clamped on the upper part of the first angle steel 1, and the lower iron frame 6 and the second fixing plate 7 are jointly clamped on the lower part of the first angle steel 1. The first fixing plate 3 is slidably connected to the upper iron frame 2, and the second fixing plate 7 is slidably connected to the lower iron frame 6. The first angle steel 1 is an L-shaped profile, and the main structure of the clamp is used to clamp the first angle steel 1 from two sides.

[0027] The adjusting component 8 is used to adjust the clamping width of the clamp to accommodate different specifications of the first angle steel 1. The adjusting component 8 is set inside the upper iron frame 2. It includes a slide groove 801 fixedly connected to the first fixed plate 3. A slide rail 806 is fixed to the inner wall of the upper iron frame 2. The slide groove 801 is slidably set on the slide rail 806, which provides limiting and guiding functions for the slide groove 801. A button 802 is slidably set on the upper part of the adjusting component 8. The button 802 passes through the side wall of the upper iron frame 2. A locking block 805 is fixedly connected to the lower surface of the button 802. The locking block 805 can selectively engage with the grooves at corresponding positions on both sides of the slide groove 801.

[0028] To achieve automatic reset of the snap-fit ​​action, the adjustment component 8 also includes a spring 803 and a second fixing block 807. The second fixing block 807 is fixed to the inner wall of the upper iron frame 2 and is fixed to the inner wall of the upper iron frame 2 by a fixing screw 804. The spring 803 is located between the button 802 and the second fixing block 807. When the button 802 is pressed and slid inward, the spring 803 is compressed, providing elastic force to drive the button 802 and the snap-fit ​​block 805 to rebound and reset, so that the snap-fit ​​block 805 automatically snaps into the groove of the slide groove 801, realizing tool-free quick locking of the clamp width.

[0029] The quick-release assembly 5 is used to quickly fix the sign 4 to the clamp body, avoiding the use of traditional screws. The quick-release assembly 5 includes a pin 502 and a latch 503, as well as a first fixing block 501 fixedly connected to one end of the pin 502. The pin 502 passes through the holes of the sign 4, the upper iron frame 2 and the lower iron frame 6 in sequence, and is detachably locked from the other end by the latch 503. A circular protrusion is provided on the outer periphery of the end of the pin 502 away from the first fixing block 501. A reserved groove is provided on the latch 503 to cooperate with the circular protrusion. After the latch 503 is sleeved on the pin 502 and rotated, the circular protrusion is inserted into the reserved groove, thereby firmly fixing the sign 4 to the angle iron.

[0030] The adjustment component 8 of the upper iron frame 2 enables the width adjustment of the first fixed plate 3, and the lower iron frame 6 is also equipped with an adjustment component 8 to lock the position of the second fixed plate 7 relative to the lower iron frame 6, so as to ensure the firmness and adaptability of the lower clamping.

[0031] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the fixing structure also includes an adjustment component 8, and the adjustment component 8 forms a specific structural cooperation and connection relationship with the aforementioned upper iron frame 2 and the first fixing plate 3, so as to realize the rapid adjustment and locking of the clamping width of the clamp.

[0032] Please refer to the following carefully. Figure 3 , Figure 5 and Figure 6 The adjustment component 8 will be described in detail below: The sliding part of the adjusting component 8 consists of a slide groove 801 and a slide rail 806. The slide groove 801 is fixedly connected to the first fixed plate 3, and the slide rail 806 is fixedly connected to the inner wall of the upper iron frame 2. The bottom of the slide groove 801 slides and engages with the slide rail 806. This matching structure of the track and the slide groove 801 provides precise guidance and limit for the reciprocating movement of the first fixed plate 3 relative to the upper iron frame 2, ensuring a smooth and stable adjustment process.

[0033] The locking part of the adjustment component 8 consists of a button 802, a locking block 805, a spring 803, and a second fixing block 807. A through hole is provided on the side wall of the upper iron frame 2. The button 802 is slidably disposed in the through hole. The locking block 805 is fixedly connected to the lower surface of the button 802. Multiple grooves with corresponding positions are provided on the outer walls of both sides of the slide groove 801. The shape of the locking block 805 is adapted to the grooves and is used to lock into the grooves to fix the position of the slide groove 801. The second fixing block 807 is fixedly connected to the inner wall of the upper iron frame 2 by a fixing screw 804. The two ends of the spring 803 abut against the inner side wall of the button 802 and the outer side wall of the second fixing block 807, respectively.

[0034] In the assembled state, the spring 803 is in a naturally extended state. Its elastic force pushes the button 802 outward and causes the locking block 805 to remain locked in the groove of the slide rail 801. At this time, the first fixing plate 3 is locked and cannot move. When the width needs to be adjusted, the button 802 is pressed inward. The button 802 overcomes the elastic force of the spring 803 and slides inward, causing the locking block 805 to disengage from the groove. At this time, applying external force to the first fixing plate 3 will cause the slide rail 801 to slide along the slide rail 806 to a new position. After releasing the button 802, the spring 803 rebounds and resets, pushing the locking block 805 again to lock into the nearest groove, completing the relocking of the position. This press-to-unlock and release-to-lock structure realizes tool-free and quick adjustment of the clamp width, greatly improving the efficiency and safety of on-site installation.

[0035] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to improve the stability of the sliding groove 801, a slide rail 806 is fixed on the inner wall of the upper iron frame 2, and the sliding groove 801 is slidably disposed on the slide rail 806.

[0036] In a preferred embodiment, in order to achieve reliable locking, the locking block 805 is engaged in the grooves at corresponding positions on both sides of the slide groove 801. The number and spacing of the grooves can be set as needed to provide multiple selectable locking positions.

[0037] In a preferred embodiment, the second fixing block 807 is fixed to the inner wall of the upper iron frame 2 by fixing wire 804. This connection method is simple in structure and reliable in fixation.

[0038] As a preferred embodiment, please refer to Figure 4To improve the ease of operation of the quick-release assembly 5, the quick-release assembly 5 also includes a first fixing block 501. The first fixing block 501 serves as the head for hand operation and is fixedly connected to one end of the pin 502. A circular protrusion is provided on the outer periphery of the end of the pin 502 away from the first fixing block 501. A reserved groove is provided on the latch 503 to cooperate with the circular protrusion. When the latch 503 is sleeved on the pin 502 and rotated, the circular protrusion is locked into the reserved groove, achieving quick and secure locking.

[0039] As a preferred embodiment, in order to enable both the upper and lower parts of the clamp to adapt to the first angle steel 1 of different sizes, the lower iron frame 6 is also provided with an adjustment component 8 with the same internal structure as the upper iron frame 2, which is used to adjust and lock the position of the second fixing plate 7 relative to the lower iron frame 6.

[0040] In a preferred embodiment, the first angle steel 1 used in this solution is an L-shaped profile, and the upper iron frame 2 of the clamp is clamped and fixed to the first fixing plate 3 and the lower iron frame 6 is clamped and fixed to the second fixing plate 7 from the two outer surfaces of the profile, respectively.

[0041] The working principle of the fixing structure of the angle steel tower clamp for fixing line identification signs of this utility model is as follows: When installation is required, first hang the upper iron frame 2 together with the first fixing plate 3 on the upper part of the first angle steel 1. If the width does not match, press the button 802 of the adjustment component 8. The button 802 will slide inward and compress the spring 803 between it and the second fixing block 807. At the same time, the locking block 805, which is fixedly connected to the button 802, will disengage from the groove of the slide 801. At this time, the first fixing plate 3 can drive the slide 801 to slide freely along the slide rail 806 on the inner wall of the upper iron frame 2. After adjusting to a suitable position that is close to the first angle steel 1, release the button 802. The spring 803 will rebound and reset, and the locking block 805 will automatically lock into the new groove to complete the width locking of the upper part.

[0042] Subsequently, the lower iron frame 6, together with the second fixing plate 7, is placed on the lower wall of the first angle steel 1. Using the same method as the upper adjustment, the lower clamping width is adjusted and locked by operating the adjustment component 8 on the lower iron frame 6.

[0043] After positioning both the upper and lower parts of the clamp body, align the nameplate 4 with the mounting holes of the upper iron frame 2 and the lower iron frame 6. Hold the first fixing block 501 of the quick-release component 5 in your hand and let the pin 502 connected to it pass through the nameplate 4, the upper iron frame 2 and the lower iron frame 6 in sequence. Put the locking buckle 503 on the other end of the pin 502 and push it to the bottom. Finally, rotate the locking buckle 503, and the annular protrusion at the end of the pin 502 will engage and lock with the reserved groove inside the locking buckle 503, thereby firmly installing the nameplate 4 on the clamp. The whole process does not require any tools and the installation is quick and convenient.

[0044] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
