Description

Technical Field

[0001] This utility model belongs to the field of wire clamp technology, and in particular relates to an adjustable contact wire clamp. Background Technology

[0002] Currently available contact wire clamps on the market are only compatible with existing contact wire models, and the wire cross-sectional area is generally 120mm². 2 150mm 2 Furthermore, these products are non-adjustable. They typically use two clamping plates to hold the contact wire and electrical connection wire, then secure them with bolts. Due to their simple structure, they are only suitable for single-type contact wires. In actual engineering projects, different models of clamps need to be customized according to site requirements, resulting in high production costs. Moreover, during on-site installation, there is a risk of construction workers being unable to distinguish the models, leading to misuse and ultimately affecting railway operational safety.

[0003] Meanwhile, based on actual operational experience, the railway industry is studying the feasibility of using contact wires with larger cross-sections. Currently, there are no matching clamps available on the market. Summary of the Invention

[0004] In view of the above problems, the purpose of this utility model is to provide a solution.

[0005] This utility model is achieved using the following technical solution:

[0006] An adjustable contact wire clamp includes two clamp bodies and a top plate;

[0007] When the two clamp bodies are joined together, an electrical connection channel is formed along their length, and the electrical connection wire can pass through the electrical connection channel and be limited.

[0008] Both ends of the two clamp bodies are equipped with movable clamping pieces. A pair of movable clamping pieces at the same end of the clamp body form a movable clamping head. The top plate is installed through the two clamp bodies along the length direction. The top plate is partially embedded between the movable clamping heads. The end of the movable clamping head cooperates with the contact wire. By adjusting the position of the top plate embedded between the movable clamping heads, the angle between the pair of movable clamping pieces can be adjusted, thereby achieving the clamping of the pair of movable clamping pieces with the contact wire.

[0009] Furthermore, it also includes bolts, at least a set of bolts, which pass through the two clamp bodies and the top plate and are locked with nuts to fix the clamp bodies and the top plate.

[0010] Furthermore, the bottom cross-section of the top plate has a smooth curved structure, and both sides are in contact with a pair of movable clips.

[0011] Furthermore, there are several top plates, and the heights of the different top plates are different.

[0012] Furthermore, the two clamp bodies form an installation channel through which the top plate passes, and the height of the installation channel exceeds the height of the top plate.

[0013] Furthermore, the top plate has a wedge-shaped structure, and the thickness of the mounting channel matches the thickness of the top plate.

[0014] Furthermore, after the two clamp bodies are joined together, the cross-section of the electrical connection channel formed along its length is circular.

[0015] Furthermore, both the clamp body and the top plate are made of CuNi2Si material.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This invention allows the wire clamp to be adapted to fit 90-200mm diameters by adjusting the size of the middle top plate. 2 The cross-sectional area of ​​the contact wire makes it more widely applicable, especially suitable for 185mm² wires. 2 Large cross-section contact wire; the top plate inside the clamp is fixed to the clamp body with bolts, making it firmly and stably installed and not easy to loosen; moreover, the clamp has a simple structure and does not require mold opening according to different models, which greatly saves manufacturing and maintenance costs. Attached Figure Description

[0019] Figure 2 A front view of an adjustable contact wire clamp provided in this embodiment of the present invention. Detailed Implementation

[0020] like Figure 1 As shown, this utility model discloses an adjustable contact wire clamp, including two clamp bodies and a top plate;

[0021] After the two clamp bodies 1 are joined together, an electrical connection channel is formed along its length. The electrical connection wire 2 can pass through the electrical connection channel and be limited. In this embodiment, the cross-section of the electrical connection channel formed by the two clamp bodies is a circular structure. The electrical connection wire passes through the electrical connection wire and is clamped by the two clamp bodies after being fixed, thus limiting the electrical connection wire.

[0022] Both ends of the two clamp bodies are equipped with movable clamping pieces 3. A pair of movable clamping pieces at the same end of the clamp body form a movable clamping head. The top plate 4 is installed through the two clamp bodies along the length direction. The top plate is partially embedded between the movable clamping heads. The end of the movable clamping head cooperates with the contact wire. By adjusting the position of the top plate embedded between the movable clamping heads, the angle between the pair of movable clamping pieces can be adjusted, thereby achieving the clamping of the pair of movable clamping pieces with the contact wire 5.

[0023] It can be considered that the ends of the pair of movable clips can be designed as arc-shaped structures or other structural shapes that can be matched with the contact wire in order to cooperate with the contact wire, as long as the contact wire is clamped and fixed, without being restricted to the specific shape or structure.

[0024] It must be pointed out that there are several top plates, and the heights of the different top plates are different; correspondingly, the two clamp bodies form an installation channel 6 for the top plate to pass through, and the height of the installation channel exceeds the height of the top plate. The thickness of the installation channel matches the thickness of the top plate. This is because, for different contact wire sizes, the opening size of the movable clamp is also different, and the angle between a pair of movable clamps is also different. Thus, the height at which the top plate is embedded between a pair of movable clamps is also different. This is because top plates of different heights are designed to accommodate contact wires of different sizes, and the height of the installation channel exceeds the height of the top plate so that the top plate can pass through the installation channel.

[0025] In this embodiment, as Figure 1 As shown, the bottom cross-section of the top plate is a smooth curved structure, and each side is in contact with a pair of movable clips. This allows the top plate to work better with the pair of movable clips. Of course, the bottom of the top plate can also be other shapes, as long as it allows the movable clips to open to the left and right. It is not necessary to be limited to a specific shape or structure.

[0026] Of course, it is also possible to consider that the top plate is a wedge-shaped structure, and the two clamp bodies form an installation channel through which the top plate passes. The thickness of the installation channel matches the thickness of the top plate, so that the top plate can be better fixed between the two clamp bodies, thereby making its installation more stable and better cooperating to open a pair of movable clamps.

[0027] Of course, when fixing the two clamp bodies and the top plate, bolt fixing can be considered. There should be at least one set of bolts, which pass through the two clamp bodies and the top plate and are locked in place by nuts 8, thus fixing the clamp bodies and the top plate. Figure 2 As shown, in this embodiment, there are 3 bolts 7, which are used to fix the clamp body and the top plate, making the top plate function more stably.

[0028] Furthermore, the top plate, i.e., the wire clamp body, in this application is made of CuNi2Si material through a die forging process, ensuring the reliability of the structural strength of the components themselves. After the applicable wire type size is adjusted via the top plate, it automatically locks and does not loosen, achieving applicability to different cross-sectional wire types. Simultaneously, the wire clamp body structure has been optimized and improved for large cross-sectional contact wire sizes, making it suitable for 185mm... 2 The contact line of the cross section.

[0029] As an example, in this embodiment, during installation, the electrical connection wires and contact wires are first fixed to the clamp body. Figure 1 Install the corresponding top plate at the indicated location. After all components are in place, lock them in place with bolts. Because the top plate is self-locking, the installation is secure and will not loosen. It is also suitable for contact wires of different cross-sections; it has strong adaptability, especially supporting 185mm² wires. 2 Large cross-section contact wires; characterized by low cost and simple operation and maintenance.

[0030] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
