Description

Technical Field

[0001] This utility model relates to the field of steel cable saddle bridge technology, specifically a cableway steel cable anti-vibration saddle bridge structure. Background Technology

[0002] In the gravitational potential energy and electrical energy conversion system, the saddle bridge provides stable guidance and support for the cableway steel cable. However, due to the large span of the cableway steel cable, the length suspended in the air is easily affected by wind. In particular, under the influence of up and down airflow, the cableway steel cable shakes up and down, affecting the stability and safety of the system, which requires special attention.

[0003] Furthermore, since cableway cables are exposed to the external air environment during operation, they are susceptible to corrosion and impurities in the air. This, combined with friction with the rollers, can negatively impact the lifespan of both the cableway cables and the rollers. Therefore, we provide a cableway cable anti-vibration saddle bridge structure. Utility Model Content

[0004] The purpose of this utility model is to provide a saddle bridge structure for preventing vibration of cableway steel cables.

[0005] The technical problem solved by this utility model is:

[0006] (1) In the prior art, cableway steel cables are easily affected by airflow in the vertical direction, resulting in vibration;

[0007] (2) In the existing technology, cableway steel cables and rollers are prone to wear and tear, which greatly reduces their lifespan.

[0008] This utility model can be achieved through the following technical solution: a cableway steel cable anti-vibration saddle bridge structure, including a vertically fixed bearing column and a horizontally symmetrically fixed steel beam on its upper part. The ends of the two steel beams are fixedly installed with mounting side plates. Each mounting side plate has multiple roller mounting plates with adjustable mounting angles on its outer side. Two rollers are rotatably installed on one side of each roller mounting plate. The roller group on each roller mounting plate guides the cableway steel cable, and the cableway steel cable alternately contacts and passes through the roller group of each roller mounting plate.

[0009] A further technical improvement of this utility model is that the angle between each roller mounting plate and the horizontal direction gradually changes, the roller mounting plate located at one end of the mounting side plate is parallel to the moving direction of the cableway steel cable at the corresponding position, and the roller mounting plate located at the other end of the mounting side plate is horizontally set.

[0010] A further technical improvement of this utility model is that: an auxiliary rod parallel to the steel beam is fixed to the top of the supporting column, and auxiliary fixing parts are symmetrically fixed at both ends of the auxiliary rod. The two welding points at the ends of the auxiliary fixing parts are welded and fixed to the top of the mounting side plate respectively.

[0011] A further technical improvement of this utility model is that: each roller mounting plate is provided with a mounting pin on one side and is rotatably set in the mounting through hole on the side wall of the mounting side plate. A positioning sleeve is slidably set on the side of the mounting through hole away from the roller mounting plate by a spline. The positioning sleeve is fitted in the square shaft set at the end of the mounting pin to restrict the rotational freedom of the mounting pin. The positioning sleeve and the mounting pin are connected by a thread to restrict the axial positioning of both.

[0012] A further technical improvement of this utility model is that a lubrication box for lubricating the cableway cable and the roller is fixed on the side wall of the first roller mounting plate where the cableway cable enters, and the lubrication box is set between the two rollers.

[0013] A further technical improvement of this utility model is that: the upper half of the lubrication box is provided with an oil storage cavity, and the middle part of the lower half is provided with a through groove. The through groove is symmetrically and rotatably equipped with clamping wheels, and each clamping wheel is rotatably connected to the lubrication box through a rotating shaft.

[0014] A further technical improvement of this utility model is that: the lubrication box is provided with a flow channel structure leading from the oil storage chamber to the clamping wheel. The flow channel structure includes an annular flow channel located below the oil storage chamber in the side wall of the through groove and a transition flow channel communicating with the annular flow channel. The transition flow channel is connected to the hollow structure inside the rotating shaft. An oil outlet jacket is provided on the clamping wheel near the side wall of the working surface. The oil outlet jacket is connected to the hollow structure of the rotating shaft, and the working surface of the clamping wheel is provided with several oil outlet holes that communicate with the oil outlet jacket.

[0015] A further technical improvement of this utility model is that a rubber layer is attached to the working surface of the engagement wheel, and an oil leakage hole corresponding to the oil outlet hole is opened on the rubber layer.

[0016] A further technical improvement of this utility model is that: the bottom of the oil storage cavity is provided with a vertical through hole that communicates with the annular flow channel, and a discharge shaft is coaxially rotatably arranged in the vertical through hole. The outer periphery of a section of the discharge shaft that passes through the vertical through hole is provided with a threaded structure for transporting lubricating oil, so that the lubricating oil is controllably introduced from the oil storage cavity into the annular flow channel.

[0017] A further technical improvement of this utility model is that the end of the discharge shaft away from the threaded structure is engaged with a gear transmission of any rotating shaft.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model sets multiple roller mounting plates and rotates roller groups on them. The installation angle of the roller mounting plates gradually changes to achieve a smooth transition of the cableway steel cable. The cableway steel cable alternately contacts the upper and lower edges of the multiple roller groups, so that the roller groups apply pressure to the upper and lower sides of the cableway steel cable. This overcomes the situation where the cableway steel cable shakes up and down under the action of airflow, and ensures the stability and safety of the entire gravity potential energy power generation system.

[0020] 2. This utility model has a lubrication box installed between the first roller group where the cableway steel cable contacts the cable. The cableway steel cable passes through the clamping rollers in the lubrication box and is driven to rotate by the friction between the clamping rollers. While the clamping rollers are rotating, they provide transportation power for the lubricating oil in the lubrication box, which overflows from the flow channel and coats the surface of the cableway steel cable, thereby protecting the clamping rollers and the cableway steel cable and extending their service life.

[0027] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0028] Example 1

[0029] Please see Figure 1-2 As shown, a cableway steel cable anti-vibration saddle bridge structure includes an installation base 1 installed on a slope or the ground, a bearing column 2 vertically fixed to the top of the installation base 1, and steel beams 3 horizontally and symmetrically fixed at a certain distance from the top of the bearing column 2. An installation side plate 4 is fixedly installed at the end of each steel beam 3 away from the bearing column 2.

[0030] Each mounting side plate 4 has several roller mounting plates 7 evenly arranged on one side. Each roller mounting plate 7 has two rollers 8 rotatably mounted on it. The side of the two rollers 8 away from the roller mounting plate 7 is jointly mounted with a side sealing plate 9. Both rollers 8 rotate relative to the side sealing plate 9. In this embodiment, there are three roller mounting plates 7. In other embodiments, there may be more than three.

[0031] The angle between each roller mounting plate 7 and the horizontal direction gradually changes. The roller mounting plate 7 located at one end of the mounting side plate 4 is parallel to the movement direction of the cableway steel cable at the corresponding position. The roller mounting plate 7 located at the other end of the mounting side plate 4 is set horizontally, so that the cableway steel cable is guided by the roller 8 and the turning transition is smooth.

[0032] Furthermore, an auxiliary rod 5 parallel to the extension direction of the steel beam 3 is fixed to the top of the supporting column 2. Auxiliary fixing parts 6 are symmetrically fixed at both ends of the auxiliary rod 5. The auxiliary fixing parts 6 have two welding points at the end away from the auxiliary rod 5, which are welded and fixed to the top edge of the mounting side plate 4, thereby enhancing the stability of the connection between the mounting side plate 4 and the steel beam 3.

[0033] Specifically, the side wall of the mounting side plate 4 is provided with a mounting through hole, and the side of the roller mounting plate 7 is provided with a mounting pin. The mounting pin is located in the mounting through hole, and a wear-resistant sleeve 10 is sleeved on its outside. The roller mounting plate 7 is rotatably connected to the mounting side plate 4 through the wear-resistant sleeve 10. The end of the mounting through hole away from the roller mounting plate 7 is provided with a spline groove, and the end of the mounting pin is provided with a square shaft 701. After adjusting the angle and posture of the roller mounting plate, the positioning sleeve 11 is inserted from the mounting side plate 4. The positioning sleeve 11 is sleeved on the outside of the square shaft 701, and the outer periphery of the positioning sleeve 11 is provided with a spline that cooperates with the spline groove of the mounting through hole, thereby completing the angle positioning of the roller mounting plate 7. At this time, the locking bolt 12 is used to pass through the positioning sleeve 11 and threadedly connected to the square shaft 701, thereby completing the positioning of the positioning sleeve 11 and the roller mounting plate 7 along the axial direction of the mounting through hole.

[0034] In this embodiment, during use, the cableway cable alternately contacts and passes over the roller assembly on each roller mounting plate 7, thereby greatly limiting the amplitude and frequency of vertical vibration when the cableway cable vibrates during operation, thus increasing safety; it should be noted that... Figure 1The state shown is when the saddle bridge structure is installed on the ground, with the cableway steel cable contacting the lower edge of the roller assembly when entering or exiting; when installed on a slope, the cableway steel cable contacts the upper edge of the roller when entering or exiting.

[0035] Example 2

[0036] Based on Example 1, since the cableway steel cable is exposed to the outdoor environment, it is prone to oxidation and contamination by impurities. After frequent contact with the roller 8, it is easy to wear out. Therefore, it is necessary to lubricate it to protect the roller 8 and the cableway steel cable.

[0037] like Figure 3-4 As shown, a lubrication box 13 is fixed to the side wall of the roller mounting plate 7 where the first roller 8 that the cableway cable contacts when it enters. The lubrication box 13 is located between the two rollers 8.

[0038] The upper half of the lubrication box 13 is provided with an oil storage cavity 1301, and the middle part of the lower half of the lubrication box 13 is provided with a through groove. Two clamping wheels 16 are symmetrically arranged in the through groove, and each clamping wheel 16 is rotatably connected to the lubrication box 13 through a rotating shaft 15.

[0039] An annular flow channel 1302 is provided in the outer peripheral sidewall of the through channel. The annular flow channel 1302 is connected to a transition flow channel 1303. One end of the rotating shaft 15 is connected to the transition flow channel 1303. The rotating shaft 15 is hollow. An oil outlet jacket 1601 is provided in the sidewall of the clamping wheel 16 near the working surface. The hollow structure in the rotating shaft 15 is connected to the oil outlet jacket 1601. A rubber layer 17 is attached to the working surface of the clamping wheel 16. The oil outlet jacket 1601 is provided with fine oil outlet holes on the side near the working surface, which correspond to the oil leakage holes opened on the rubber layer 17.

[0040] The bottom of the oil storage chamber 1301 is provided with a vertical through hole that communicates with the annular flow channel 1302. A discharge shaft 14 is coaxially arranged in the vertical through hole. The outer periphery of the discharge shaft 14, which passes through the vertical through hole, is provided with a thread structure similar to an auger. The discharge shaft 14 is rotatably connected to the lubrication box 13. The end of the discharge shaft 14 away from the thread structure is engaged with any one of the rotating shafts 15 for gear transmission.

[0041] In use, the cableway cable passes between the two clamping wheels 16 and rotates under the friction between the cableway cable and the clamping wheels 16. This drives the discharge shaft 14 via gear transmission. The lubricating oil enters the annular flow channel 1302 under the transport of the threaded structure, and then enters the oil outlet jacket 1601 through the transition flow channel 1303 and the hollow structure of the rotating shaft 15. The oil seeps out from the oil outlet hole and the oil leakage hole to lubricate the cableway cable and the roller 8.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
