Description

Technical Field

[0001] This utility model belongs to the field of crossarm technology for power towers, and in particular relates to an installation structure for high and low voltage crossarms of power towers. Background Technology

[0002] High-voltage and low-voltage crossarms in power transmission towers are key components supporting transmission lines. A well-designed structure ensures stable line operation, and includes the crossarm itself and side clamps.

[0003] Currently, crossarms are mostly installed on the outside of the column using clamps, and the crossarms are suspended on the outside. Affected by high-altitude winds, they are prone to significant swaying, affecting the stability of the installation.

[0004] To address the aforementioned issues, this application proposes a high- and low-voltage crossarm installation structure for power transmission towers. Utility Model Content

[0005] The purpose of this utility model is to provide a high and low voltage crossarm installation structure for power transmission towers, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a high and low voltage crossarm installation structure for power towers, including a crossarm and a first clamp and a second clamp on its outer side. The crossarm is fixedly connected to the first clamp through a connecting plate at the front.

[0008] The first clamp and the second clamp both have side plates extending from their left and right sides and are fixed by bolts. The front of the crossarm has a connecting rod that is fixedly connected to the side plates on both sides of the first clamp. The front end of the connecting rod has a protrusion with a front opening structure that engages with the slots inside the side plates on both sides of the second clamp.

[0009] The second clamp has a T-shaped block in front of the side plate on both sides, and a locking block is provided on its side to be inserted into the opening groove of the protrusion. The upper and lower plates of the T-shaped block are fixed with blocking pads to hold the bolts.

[0010] Preferably, the protrusion is located in the middle of the upper and lower bolts on the side plate, and the front end is a square groove.

[0011] Preferably, the upper and lower plates of the T-shaped block and the locking block form two right-angle mechanisms, and the locking blocks of adjacent right-angle mechanisms are connected to each other to form a T-shaped structure.

[0012] Preferably, the opposite surfaces of adjacent card blocks are provided with through slots, forming a circular groove after docking.

[0013] Preferably, the T-block has a pin at the front, with one end of the pin inserted into the through groove.

[0014] Preferably, the protrusion applies a supporting force to the crossarm via a connecting rod through its engagement with the slot.

[0015] Preferably, the protrusion applies tension to the crossarm and the first clamp via a connecting rod through its engagement with the slot.

[0016] This utility model has the following beneficial effects:

[0017] This utility model connects adjacent first clamps with connecting rods and is fixed to both sides of the first clamps with T-blocks. Thus, after the crossarm is installed, it provides support for the crossarm at multiple lateral positions of the first clamps. At the same time, it uses adjacent clamps to provide support, thereby solving the problem of suspension outside a single mechanism and preventing large swaying caused by high-altitude winds.

[0018] This invention reinforces the T-shaped block by inserting the locking block into the protrusion and then using a pin, thereby causing the inner side of the T-shaped block to tightly press against the connecting bolt. The blocking pad on the outer edge of the bolt forms a covering effect to increase frictional resistance. Thus, after the crossarm is installed, it can simultaneously reinforce the connection of the adjacent first clamp, effectively preventing the problem of loose connection.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-4 As shown, this utility model is a high and low voltage crossarm installation structure for power towers, including a crossarm 1 and a first clamp 21 and a second clamp 22 on its outer side. The crossarm 1 is fixedly connected to the first clamp 21 through a connecting plate 211 at the front. The second clamp 22 can also be a clamp mechanism installed on the side of an adjacent crossarm 1.

[0033] Side plates 201 are fixed to both the left and right sides of the first clamp 21 and the second clamp 22. Adjacent side plates 201 are fixed by bolts, with the bolts located near the upper and lower ends of the side plates 201. A connecting rod 31 is fixedly connected to the front of the crossarm 1, with one end of its extension fixedly connected to the side plates 201 on both sides of the first clamp 21. A forward-opening protrusion 311 is fixedly provided at the front end of the connecting rod 31, which engages with the slots 2011 inside the side plates 201 on both sides of the second clamp 22. The slots 2011 are through grooves. After the protrusion 311 engages with the slots 2011, the protrusion 311 applies a supporting force to the crossarm 1 through the connecting rod 31 by engaging with the slots 2011, and at the same time applies a tensile force to it and the first clamp 21. Thus, the force applied by the second clamp 22 can be used to solve the problem of the crossarm being suspended outside a single mechanism, achieving the effect of multi-point force bearing and reducing the impact of high-altitude wind force.

[0034] The side plates 201 on both sides of the second clamp 22 are provided with T-shaped blocks 32 in front, and the side plates are fixedly connected with locking blocks 321, which are inserted into the opening groove of the protrusion 311. The upper and lower plates of the T-shaped block 32 are fixedly connected with blocking pads 323 that abut against the end edge of the bolt. The blocking pads are made of silicone rubber and form a covering effect on the outer edge under the action of extrusion pressure, so as to prevent the bolt from loosening.

[0035] Furthermore, the protrusion 311 is located in the middle of the upper and lower bolts of the side plate 201, and the front end is a square groove. The outer edge of the protrusion 311 is attached to the inner wall of the slot 2011.

[0036] Furthermore, the upper and lower plates of the T-block 32 and the locking block 321 form two right-angle mechanisms. The locking blocks 321 of adjacent right-angle mechanisms are connected to each other to form a "T"-shaped T-block 32. The upper and lower plates extend to the upper and lower edges of the side plate 201, respectively.

[0037] Furthermore, the opposite surfaces of adjacent locking blocks 321 are provided with through grooves 322, which form a circular groove after docking, and the blocking pad on the inner side of the groove covers the end of the bolt.

[0038] Furthermore, a pin 33 is provided in front of the T-block 32, with one end of the pin inserted into the inside of the through groove 322. Under the action of the squeezing force, the upper and lower parts of the T-block 32 are pushed up and down, thereby fixing the protrusion 311. At the same time, the installation of the pin 33 will also apply a tightening force to the side plate 201 on the T-block 32, so that the blocking pad 322 can tightly cover the bolt.

[0039] Understandably, this utility model can achieve multi-point support during installation, solve the problem of swaying caused by wind during crossarm suspension installation, and strengthen the bolts to prevent loosening due to external forces.

[0040] A specific application of the operation process of this embodiment is as follows: First, the adjacent first clamp 21 and second clamp 22 are connected to the outside of the column. During the connection process, the protrusion 311 at the front end of the connecting rod 31 is engaged with the inside of the slot 2011. After the bolt is installed, the locking block 321 on the side of the T-block 32 is inserted into the opening of the protrusion 311, and the blocking pad 323 is pressed against the outer edge of the bolt to form a certain coverage. Finally, the pin 33 is inserted into the through groove 322 to tighten the locking block 321 to form a fixation. At this time, the crossarm 1 is supported by the connecting plate 211 and the connecting rod 31 in the lateral position. The adjacent clamps can be used to support the crossarm 1, solving the problem of single mechanism suspension.
