Three fixing kits are fitted on the outer surface of the pole. The outer surface of the topmost fixing kit is provided with an inclined brace hinge frame. Two inclined braces are provided on the inclined surface of the inclined brace hinge frame. The top of each of the two inclined braces is provided with an angled support fixing strip. The outer surfaces of the bottom two fixing kits are provided with a shock-absorbing structure.

[0005] Support rod one and support rod two are provided on the side of the two shock-absorbing structures away from the upright. The shock-absorbing structure includes an angled hinge frame. A connecting block is fixedly installed on the side of the angled hinge frame away from the upright. A shock-absorbing spring kit is fixedly installed on the side of the connecting block away from the angled hinge frame. Support rod one is connected to the side of the shock-absorbing spring kit away from the connecting block. One end of support rod two is connected to the side of the other shock-absorbing spring kit away from the connecting block.

[0006] Preferably, the first support rod and the second support rod are arranged at an acute angle, and a connector is provided at the intersection of the first support rod and the second support rod for connection and fixation.

[0007] Preferably, the shock-absorbing spring kit consists of an internal spring, a telescopic rod, and an external rubber sleeve.

[0008] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0009] The tunnel contact network boom uses shock-absorbing spring kits, connecting blocks, and angled hinge frames to connect and support support rod one and support rod two on the fixed kit, thereby achieving the stability of the boom and the telescopic protection of the contact network conductors on the boom provided by the shock-absorbing spring kits.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-3 As shown, the present invention proposes a tunnel contact network boom, including a pole 1, a top arc-shaped connecting plate 2 fixedly installed on the top of the pole 1, three fixing kits 3 sleeved on the outer surface of the pole 1, an inclined brace hinge frame 10 with an inclined angle on the outer surface of the topmost fixing kit 3, two inclined braces 9 on the inclined surface of the inclined brace hinge frame 10, an inclined support fixing strip 4 at the top of each of the two inclined braces 9, and a shock-absorbing structure 5 on the outer surface of the bottom two fixing kits 3.

[0018] Two shock-absorbing structures 5 are provided with support rod 1 6 and support rod 2 8 on the side away from the upright 1. The shock-absorbing structure 5 includes an angled hinge frame 503. A connecting block 502 is fixedly installed on the side of the angled hinge frame 503 away from the upright 1. A shock-absorbing spring kit 501 is fixedly installed on the side of the connecting block 502 away from the angled hinge frame 503. Support rod 1 6 is connected to the side of the shock-absorbing spring kit 501 away from the connecting block 502. One end of support rod 2 8 is connected to the side of the other shock-absorbing spring kit 501 away from the connecting block 502.

[0019] It should be noted that one end of support rod 28 is equipped with components for supporting the contact wire and other components.

[0020] Specifically, the shock-absorbing structure 5 is fixed to the upright 1 by the oblique hinge frame 503 and the fixing kit 3, and then the support rod 1 6 and the support rod 2 8 are formed into a triangular bracket by the connecting block 502 and the shock-absorbing spring kit 501 to support the stability of the contact wire.

[0021] In an optional embodiment, support rod 6 and support rod 8 intersect at an acute angle, and a connector 7 is provided at the intersection of support rod 6 and support rod 8 for connection and fixation.

[0022] It should be noted that support rod 6 and support rod 8 provide a stable triangular support.

[0023] In an optional embodiment, the shock-absorbing spring kit 501 consists of an internal spring, a telescopic rod, and an external rubber sleeve.

[0024] It should be noted that the telescopic rod limits the extension and retraction positions of support rod 6 and support rod 8, while the spring limits the extension and retraction range of support rod 6 and support rod 8.

[0025] Working principle: When a boom is needed to support the contact wire, the arc-shaped connecting plate 2 and the upright 1 are first fixed to the top of the tunnel with bolts. Then, the three fixing kits 3 are fixed to the outer surface of the upright 1. At the same time, the diagonal brace hinge frame 10 is fixed to the outer surface of the top fixing kit 3. Then, the two diagonal braces 9 are fixed to the diagonal brace hinge frame 10. Then, the upright 1 is fixed to the top of the tunnel by two angled support fixing strips 4. After the upright 1 is installed, the support rod 1 6 and the support rod 2 8 are fixed to the upright 1 by the shock-absorbing structure 5. The two shock-absorbing structures 5 are installed on the outer surface of the two bottom fixing kits 3. The support rod 1 6 and the support rod 2 8 are connected by the connector 7 to form a triangular support frame to improve the stability of the boom.

[0026] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
