Description

Technical Field

[0001] The invention relates to the technical field of subway rigid contact network installation, in particular to a rigid contact network busbar joint auxiliary adjustment device. Background Art

[0002] With the rapid development of urban rail transit, rigid contact network has been widely used as an important power supply method. Rigid contact network is mainly composed of busbars, contact wires and other components, among which the connection quality of the busbar plays a key role in the performance and safety of the entire contact network system.

[0003] During the installation of the rigid contact network bus, in order to ensure the precise docking between the busbars, a rough adjustment operation is generally performed first. The purpose of the rough adjustment is to preliminarily correct the large position deviation of the busbar caused by construction errors, foundation structure deviations and other factors. However, due to the complex and changeable actual construction environment, the accuracy of the rough adjustment is difficult to be effectively guaranteed, and the rough adjustment amplitude is often large. This large rough adjustment amplitude will cause the angle deviation of the busbar to be too large, making it difficult to correctly install the fixed part of the existing busbar joint auxiliary adjustment device on the busbar, which seriously affects the smooth progress and installation efficiency of the installation work.

[0004] In addition, the common adjustment devices currently use screw twisting to make fine adjustments. Although this adjustment method has certain convenience and cost advantages, it lacks an effective limit mechanism. After the busbar is adjusted, it is punched, and the continuous vibration generated will inevitably be transmitted to the busbar and its joint adjustment device. Under the action of vibration, it is easy to loosen, which leads to the displacement of the position between the busbars. Summary of the invention

Regardless of the slight tilt angle between the two buses or the large angle deviation, the joint adjustment mechanism can be accurately adapted and smoothly installed.

[0048] 3. The limiting mechanism can quickly limit the round rod, threaded rod and one-way telescopic rod to avoid drilling the busbar after adjusting the busbar. The continuous vibration generated will inevitably be transmitted to the busbar and its joint adjustment device. Under the action of vibration, the round rod and threaded rod are prone to slight rotation, which will cause the position of the busbar to shift, effectively improving the working stability.

[0070] like Figure 6-8As shown, in the present embodiment, the limiting mechanism 300 includes the following parts: two square plates 310 are provided, which are respectively fixed to the inner walls on both sides of the shell 120, a spring telescopic rod 313 is fixedly connected to the outer wall of the square plate 310, and a square groove 211 is provided on the inner wall of the sliding tube of the spring telescopic rod 313, and an outer wall of one end of the sliding rod of the spring telescopic rod 313 is fixedly connected to an inclined block 115, and the outer wall of the inclined block 115 is slidably plugged into the inside of the square groove 211, and a ring frame 114 is fixedly connected to one end of the sliding rod of the spring telescopic rod 313, and a square plate 4 320 is fixed between the sliding rods of the two spring telescopic rods 313, and a circular hole 321 is provided on the outer wall of the square plate 4 320, and three spring telescopic rods 4 322 are fixedly connected at equal angles to the inner wall of the circular hole 321, and an inclined block 213 is fixedly connected to one end of the spring telescopic rod 4 322 3, the ring frame 230 is fixed to the outer wall of the housing 120 near the position of the hexagonal block 1 211, and a group of square rods 324 are provided, which are fixed at one end of the square plate 4 320, and the square rods 324 are slidably plugged into the outer wall of the L-shaped frame 113, and the outer wall of one group of square rods 324 is snap-fitted with the decacorner block 231, and the square plate 5 326 is fixed to the outer wall of the other end of the square plate 4 320, and the outer wall of the square plate 5 326 is plugged into the square hole 123 The pressing mechanism 400 includes the following parts: a frame 410 is slidably plugged into the inside of the square groove 129, and an elastic gasket 411 is fixed to the inner wall of the square groove 129; a sliding hole 412 is opened at the outer wall of the shell 120 near the position of the square groove 129; and the sliding hole 412 is slidably plugged into the sliding rod of the spring telescopic rod 313 and the inclined block 1 315.

[0071] In specific implementation, after the adjustment is completed, the personnel press the frames 410 on both sides to separate the outer wall of the frame 410 from the corresponding inclined block 1 315, and the square plate 4 320 is quickly driven to move close to the outer wall of the shell 120 due to the rebound of the spring telescopic rod 313. During this period, the inclined block 2 323 will be separated from the ring frame 2 330, and the spring telescopic rod 4 322 will rebound, so that the inclined block 2 323 is close to the outer wall of the hexagonal block 1 211, limiting the round rod 210, and the square rod 324 slides and plugs into the corresponding plane of the decacornal block 231 to limit the threaded rod 230. At the same time, the square plate 5 32 6 will be plugged into the corresponding square hole 2 124 along the position of the square hole 123 to limit the length of the one-way telescopic rod 122. The round rod 210, the threaded rod 230 and the one-way telescopic rod 122 can be quickly limited by the limiting mechanism 300 to avoid punching the bus after adjusting the bus. The continuous vibration generated will inevitably be transmitted to the bus and its joint adjustment device. Under the action of vibration, the round rod 210 and the threaded rod 230 are prone to slight rotation, which will cause the position between the bus to shift, effectively improving the working stability.

[0072] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0073] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
