Description

Technical Field

[0001] This utility model belongs to the field of flexible tracking bracket technology, specifically, it relates to an easily replaceable sliding bearing structure for the rotating beam of the side column of a flexible tracking bracket. Background Technology

[0002] Flexible photovoltaic supports are characterized by large span, high clearance, and few foundations, making them adaptable to more complex terrains, such as complex mountains, sewage treatment plants, deserts, and various water surfaces, and have broad application prospects.

[0003] Existing flexible photovoltaic (PV) support systems come in various types. For example, patent application number CN202211673387.8 discloses a flexible PV support system and a PV power station, including columns, with multiple columns spaced apart on a base surface, each column including two first side columns; first beams installed on the top of each first side column; a flexible support body disposed between the two first beams, the flexible support body including at least two load-bearing cables; and a rigid support body disposed on the side of each first beam away from the flexible support body. The flexible support body and the rigid support body constitute the load-bearing body of the PV module. The PV power station includes the aforementioned flexible PV support system.

[0004] The aforementioned existing flexible photovoltaic support system has a first mounting base fixedly installed on the upper end of the first side column. The first beam is rotatably mounted on the first mounting base, and the first beam and the first mounting base are rotatably connected through a slewing bearing assembly. Due to its structure, and because the slewing bearing assembly needs to withstand stress for a long time, damage is inevitable during use. If the slewing bearing is damaged or fails, the entire system will fail. Furthermore, the relevant load-bearing cables have sufficient preload tension. Therefore, when the slewing bearing is repaired or replaced, the entire tracking support system needs to be completely dismantled and reinstalled to replace the relevant rotating structure. This results in high overall maintenance costs and cumbersome maintenance procedures, severely reducing the effectiveness of use. Utility Model Content

[0005] The main technical problem to be solved by this utility model is to provide an easily replaceable sliding bearing structure for the rotating beam of the side column of a flexible tracking bracket. This structure can solve the problems mentioned in the background art. The overall structure is simple, and the bearings of the failed rotating parts can be replaced without complete disassembly. It is convenient for inspection and maintenance, and has the advantages of compact structure, high strength, self-lubrication, and aging resistance.

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

[0007] A flexible tracking bracket side column rotating beam with an easily replaceable sliding bearing structure includes a support base for mounting the rotating beam. A sliding bearing assembly mounting position is provided on the side of the support base opposite to the direction of force on the steel cable. Two sliders arranged vertically are provided at the sliding bearing assembly mounting position. The two sliders are fastened to the support base by a mounting assembly. The middle part of the rotating beam is rotatably connected to the sliders through a rotating shaft. The sliders are used to rotate the rotating beam onto the support base.

[0008] The following are further optimizations of the above technical solution by this utility model:

[0009] The overall structure of the support base includes two frame plates arranged at intervals, with a tensioning support plate between the two frame plates. The two sides of the tensioning support plate are fixedly connected to the corresponding frame plates.

[0010] Further optimization: The mounting position of the sliding bearing assembly is a protrusion on the frame plate near the end of the tensioning support plate. The two protrusions and the tensioning support plate form a sliding block chamber, which is a through groove.

[0011] Further optimization: A support U-shaped groove is provided on the upper surface of the tensioning support plate. The support U-shaped groove is used to assist in supporting the rotating shaft when changing the slider.

[0012] Further optimization: Grooves are respectively opened on the side surfaces of the two sliders that are close to each other. After the two sliders are connected, the two grooves form a support hole. The inner surface size of the support hole matches the outer surface size of the rotating shaft.

[0013] Further optimization: Through holes are opened on both sides of the slider. After the two sliders are connected, the corresponding two through holes are connected to each other, and a screw can pass through the two connected holes at the same time.

[0014] Further optimization: The mounting assembly includes fasteners spaced vertically, with two fastening bolt kits passing between the two fasteners;

[0015] The fastening bolt kit passes through the upper fastener, the through holes of the two sliders, and the lower fastener in sequence from top to bottom, and fixes the sliders on the support base.

[0016] Further optimization: After the slider is fixedly installed in the slider chamber, the side of the slider away from the tensioning support plate protrudes outward and is located outside the support seat.

[0017] Further optimization: The rotating shaft is also equipped with anti-corrosion and wear-resistant plates, which are located between the slider and the rotating beam.

[0018] Further optimization: The upper surface of the tensioning support plate of the support base extends to the top of the frame plate, so that the upper end of the tensioning support plate forms a blocking part.

[0019] Further optimization: The slider is made of ultra-high molecular weight polyethylene, and the anti-corrosion and wear-resistant sheet is made of stainless steel.

[0020] The present invention, by adopting the above-described technical solution, has at least the following beneficial effects:

[0021] 1. This utility model uses two sliders connected together to achieve stable support and installation of the rotation axis of the rotating beam, so that the rotating beam can be rotated and installed on the support base, which is convenient for assembly and installation. The two sliders are fixedly installed on the support base by the cooperation of two fasteners and two fastening bolt kits, which is convenient for assembly and installation; and can stably restrict the position of the sliders, improving the installation effect of the rotating beam.

[0022] 2. In this utility model, the tension of the load-bearing cable on the rotating beam can be applied to the slider. The side of the slider near the rotating beam protrudes towards the rotating beam and is higher than the side of the frame plate. The slider can provide shaft lubrication and lateral surface lubrication for the rotating beam, improving the performance. Furthermore, the slider and the support can also be used to support the pressure and gravity transmitted by the rotating beam, improving the performance.

[0023] 3. The slider in this utility model is made of ultra-high molecular weight polyethylene material, which has high overall strength and features self-lubrication, corrosion resistance, and aging resistance, making it an ideal material for the rotary bearing of the flexible tracking bracket.

[0024] 4. In this utility model, the slider adopts a flexible tracking bracket that is suspended high, and the whole is in a state of tension and stress. Once the slider is damaged and needs to be repaired and maintained, only the fastening bolt kit needs to be disassembled before the two sliders can be disassembled and replaced. During the replacement process, the rotating shaft is located in the support U-shaped groove of the tensioning support plate. At this time, the cooperation between the tensioning support plate and the support U-shaped groove is used to provide auxiliary support for the rotating shaft. There is no need to disassemble the rotating beam, so the repair and replacement of the slider can be completed quickly. After the slider is replaced, the fasteners and fastening bolt kit are reinstalled, and the replaced slider can be fixedly installed on the support base, and the rotating beam can be rotated and supported again, which is convenient for use.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model; all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] Example 1: As Figure 1-9 As shown: A flexible tracking bracket side column rotating beam with easily replaceable sliding bearing structure includes a support base 3 for rotating the rotating beam 1. A sliding bearing assembly mounting position is provided on the side of the support base 3 opposite to the direction of force on the steel cable. Two sliders 2 arranged vertically are provided at the sliding bearing assembly mounting position. The two sliders 2 are fastened to the support base 3 by a mounting assembly. The middle part of the rotating beam 1 is rotatably connected to the sliders 2 through a rotating shaft 101. The sliders 2 are used to rotate the rotating beam 1 onto the support base 3.

[0039] The rotating shaft 101 is fixedly installed at the middle position of the rotating beam 1, and the rotating shaft 101 passes through the left and right sides of the rotating beam 1. The connection between the rotating shaft 101 and the rotating beam 1 is a fixed connection.

[0040] The rotating beam 1 is located on the side of the support base 3 opposite to the direction of force on the steel cable, and steel cable connecting seats for connecting steel cables can be fixedly installed on both ends of the rotating beam 1.

[0041] The overall structure of the support base 3 includes two spaced frame plates 303, and a vertical plate 305 is fixedly installed between the two frame plates 303 near one side.

[0042] A tensioning support plate 301 is also provided between the two frame plates 303. The tensioning support plate 301 and the upright plate 305 are arranged at intervals, and the two sides of the tensioning support plate 301 are fixedly connected to the corresponding frame plates 303 respectively.

[0043] The sliding bearing assembly mounting position includes a protrusion 307 integrally connected to the frame plate 303 on the side near the tensioning support plate 301, and the two protrusions 307 and the tensioning support plate 301 enclose a slider compartment 302.

[0044] In this embodiment, the slider compartment 302 is a through groove.

[0045] The height of the slider compartment 302 matches the overall height of the two sliders 2 when they are joined together.

[0046] In this embodiment, a support U-shaped groove 306 is provided on the upper surface of the tensioning support plate 301. The bottom surface of the support U-shaped groove 306 is slightly lower than the outer surface of the rotating shaft 101 and they do not contact each other during normal operation.

[0047] With this design, after the rotating beam 1 is assembled onto the support base 3, the rotating shaft 101 is located on the upper side inside the support U-shaped groove 306. At this time, the support U-shaped groove 306 and the rotating shaft 101 are not in contact. When the slider 2 is worn, the inner side of the support U-shaped groove 306 contacts the outer surface of the rotating shaft 101 to play an auxiliary support role. At this time, the slider 2 needs to be replaced.

[0048] During replacement, a special expansion tool is needed to push the inner end face of the rotating shaft 101 in the opposite direction of the force applied to the steel strand, causing the contact surface between the rotating beam 1 and the slider 2 to separate. At this time, the inner side of the support U-shaped groove 306 contacts the outer surface of the rotating shaft 101, providing auxiliary support. Under the action of the steel strand and the expansion tool, the original state remains unchanged. Thus, the slider 2 can be replaced. After replacement, the expansion tool is released, and the normal state is restored under the action of the pre-tightening force of the steel strand and the tightening force of the fasteners 201 and bolts.

[0049] In this embodiment, the upper end of the supporting U-shaped groove 306 is an open opening, which facilitates the assembly of the rotating beam 1.

[0050] A tension hole 304 is provided on the frame plate 303 of the support base 3 at the lower position on the side near the protrusion 307.

[0051] In this embodiment, the support base 3 is fixedly installed on the top of the side column of the photovoltaic flexible support. A stay cable can be inserted into the tension hole 304. The other end of the stay cable is fixedly connected to the foundation. By inserting the stay cable into the tension hole 304, the support base 3 can be stabilized when the side column is tightened, the preload on the load-bearing cable can be balanced, and the impact of various loads on the frame can be offset.

[0052] There are two sliders 2. The two sliders 2 have grooves on their sides that are close to each other. After the two sliders 2 are connected, the two grooves form a support hole 204. The inner surface size of the support hole 204 matches the outer surface size of the rotating shaft 101.

[0053] In this embodiment, through holes 203 are respectively provided on the slider 2 near both sides. After the two sliders 2 are connected, the corresponding two through holes 203 are interconnected, and a screw can pass through the two interconnected holes at the same time.

[0054] The installation assembly includes fasteners 201 arranged at intervals, with two fastening bolt kits 202 passing between the two fasteners 201.

[0055] In this embodiment, the spacing between the two fastening bolt kits 202 matches the spacing between the two through holes 203 on each slider 2.

[0056] The overall length of the fastener 201 matches the distance between the two frame plates 303 on the support base 3, which are located away from each other on their two sides.

[0057] like Figure 1 and Figure 7As shown, in this design, during assembly, the rotation shaft 101 of the rotating beam 1 is placed in the support U-shaped groove 306 on the support base 3. Then, the two sliders 2 are arranged vertically and placed in the slider compartment 302. At this time, one side of the slider 2 is in contact with the tensioning support plate 301. Then, two fasteners 201 are placed on the upper and lower sides of the two sliders 2 respectively. The fastening bolt kit 202 is inserted from top to bottom through the upper fastener 201, the through hole 203 of the two sliders 2, and the lower fastener 201. The fastening bolt kit 202 is then adjusted. At this time, the upper side... The fasteners 201 on the upper side and the lower fastener 201 move towards each other and press the slider 2. When the two fasteners 201 respectively abut against the protrusions 307 on the support base 3, the fixed installation operation of the two sliders 2 can be completed, so that the sliders 2 are fixedly installed on the support base 3, which is convenient for assembly and installation. At this time, the circular support hole 204 formed after the two sliders 2 are connected matches the outer surface of the rotating shaft 101, which is used to rotate and support the rotating shaft 101, thereby realizing the rotation of the rotating beam 1 on the support base 3, which is convenient for assembly and installation.

[0058] In this embodiment, the slider 2 is made of ultra-high molecular weight polyethylene material, which has high overall strength and features self-lubrication, corrosion resistance, and aging resistance, making it an ideal material for the rotary bearing of the flexible tracking bracket.

[0059] In this embodiment, the slider 2 is suspended in the air using a flexible tracking bracket, and is in a state of tension. If the slider 2 is damaged and needs to be repaired and maintained, firstly, a special tensioning tool is used to push the inner end of the rotating shaft 101 against the direction of the force on the steel strand, causing the rotating beam 1 to separate from the contact surface of the slider 2. At this time, the inner side of the support U-shaped groove 306 contacts the outer surface of the rotating shaft 101 to provide auxiliary support. The steel strand and the tensioning tool maintain their original state. Then, the fastening bolt kit 202 is disassembled to separate the two fasteners 201 from the support base 3, exposing the two sliders 2, and the upper part of the slider compartment 302... Neither the top nor bottom will obstruct the slider 2, making it easy to replace the two sliders 2. During the replacement process, the rotating shaft 101 is located in the supporting U-shaped groove 306. At this time, the cooperation of the tensioning support plate 301 and the supporting U-shaped groove 306 is used to provide auxiliary support for the rotating shaft 101. Without disassembling the rotating beam 1, the inspection and replacement of the slider 2 can be completed quickly. After the slider 2 is replaced, the fasteners 201 and the fastening bolt kit 202 are reinstalled, and the replaced slider 2 can be fixedly installed on the support base 3, and the rotating beam 1 can be rotated and supported again for convenient use.

[0060] In this embodiment, as Figure 7-8As shown, after the slider 2 is fixedly installed in the slider chamber 302, the side of the slider 2 away from the tension support plate 301 protrudes outward and is located outside the support base 3.

[0061] This design allows the side of the slider 2 closest to the rotating beam 1 to be located outside the slider compartment 302, thereby providing shaft lubrication and lateral surface lubrication for the rotating beam 1 and improving its performance.

[0062] The rotating shaft 101 is also fitted with a corrosion-resistant and wear-resistant sheet 4, which is located between the slider 2 and the rotating beam 1.

[0063] The anti-corrosion and wear-resistant sheet 4 has a central hole 401 in the middle, and the anti-corrosion and wear-resistant sheet 4 is sleeved on the rotating shaft 101 through the central hole 401.

[0064] The upper and lower sides of the anti-corrosion and wear-resistant sheet 4 are integrally connected with folded edges 402. The folded edges 402 and the main body of the anti-corrosion and wear-resistant sheet 4 are arranged at an angle of greater than or equal to 90 degrees. The folded edges 402 extend towards the side closer to the rotating beam 1.

[0065] With this design, the anti-corrosion and wear-resistant plate 4 is inserted through the rotating shaft 101 and located between the slider 2 and the rotating beam 1. The anti-corrosion and wear-resistant plate 4 can improve the overall anti-corrosion and wear resistance of the rotating beam 1 and the slider 2, and improve the performance.

[0066] Example 2: Figure 10-11 As shown, based on the above embodiment 1, in this embodiment 2, the upper end surface of the tensioning support plate 301 of the support base 3 extends to the top of the frame plate 303, so that the upper end of the tensioning support plate 301 forms a blocking part.

[0067] The length of the fastener 201 is greater than the distance between the two frame plates 303 and their opposite sides; the fastening bolt kit 202 is located at both ends of the fastener 201 and is arranged on one side of the outer side of the two frame plates 303.

[0068] In this embodiment 2, the through hole 203 is no longer provided on the slider 2.

[0069] With this design, during assembly, the rotation shaft 101 of the rotating beam 1 is placed in the support U-shaped groove 306 on the support base 3. Then, the two sliders 2 are arranged vertically and placed in the slider compartment 302. At this time, one side of the slider 2 is in contact with the tensioning support plate 301. Then, two fasteners 201 are placed on the upper and lower sides of the two sliders 2 respectively. The fastening bolt kit 202 is inserted from top to bottom through the upper fastener 201 and the lower fastener 201, and the fastening bolt kit 202 is located on the outside of the support base 3. At this time, the fastening bolt kit 202 is pre-tightened. The upper and lower fasteners 201 move closer to each other and press the slider 2 together. When the two fasteners 201 abut against the protrusions 307 on the support base 3, the two sliders 2 can be fixedly installed on the support base 3, which is convenient for assembly and installation. The support hole 204 formed after the two sliders 2 are connected at this time matches the outer surface of the rotating shaft 101 and is used to rotate and support the rotating shaft 101, thereby enabling the rotating beam 1 to be rotated and installed on the support base 3, which is convenient for assembly and installation.

[0070] In this embodiment, after the fastener 201 is installed, the upper fastener 201 abuts against the blocking part on the tensioning support plate 301, and the lower fastener 201 abuts against the frame plate 303. Through this abutting force, it can be used to support the pressure and gravity transmitted by the rotating beam 1, thereby improving the performance.

[0071] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
