[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 5 As shown, a supporting tire frame includes three groups of first positioning inner rings 1 and three groups of second positioning inner rings 2, and the outer sides of the three groups of the first positioning inner rings 1 and the three groups of the second positioning inner rings 2 are all provided with positioning outer rings 3, and multiple groups of radial connecting rods 4 are fixedly connected between the positioning outer rings 3 and the first positioning inner rings 1 and the second positioning inner rings 2, and the inner side of the first positioning inner ring 1 is fixedly connected with a recessed block 5, and the inner side of the second positioning inner ring 2 is fixedly connected with a clamping rod 6, and the interior of the recessed block 5 is provided with a clamping mechanism, and the clamping mechanism is used to limit the first positioning inner ring 1 and the second positioning inner ring 2.

[0027] In the past, the support tire frame required radially arranged rows of concrete piers, each row of concrete piers included at least two radially aligned piers, and multiple rows of concrete piers were arranged at intervals along the circumferential direction, and finally supported the annular structure in the initial state, and the support tire frame required on-site construction of piers, and each row of piers needed to be marked and aligned for construction. The process was relatively cumbersome, requiring the staff to have professional skills, and was relatively time-consuming and labor-intensive. In order to solve the above problems, when this embodiment is used, first, multiple groups of first positioning inner rings 1 and second positioning inner rings 2 are welded to the positioning outer ring 3 through radial connecting rods 4 to form multiple integral parts, which are transported to the construction site, and the first positioning inner ring 1 is placed in the area where construction is required. At this time, the second positioning inner ring 2 is lifted by a crane, and the edge of the second positioning inner ring 2 is aligned with the edge of the first positioning inner ring 1, and is lowered vertically, and the second positioning inner ring 2 is fixed to the outer ring 3. During the movement, the clamping rod 6 is driven to move vertically downward. During the downward movement, the clamping rod 6 squeezes the locking mechanism, and the locking mechanism moves under the force. When the clamping rod 6 falls accurately into the interior of the recessed block 5, the locking mechanism is reset to fix the position of the clamping rod 6. At this time, the clamping rod 6 cannot move, thereby limiting the first positioning inner ring 1 and the second positioning inner ring 2. Subsequently, in the subsequent welding process of the first positioning inner ring 1 and the second positioning inner ring 2, the first positioning inner ring 1 and the second positioning inner ring 2 cannot shake, thereby achieving a stable effect and solving the troublesome problem of on-site pier construction. The above-mentioned splicing method is more convenient for installation and also facilitates transportation to a certain extent. Finally, the remaining two groups of the first positioning inner ring 1 and the second positioning inner ring 2 are assembled through the above-mentioned installation to form a supporting tire frame.

[0028] like Figure 3 and Figure 4 As shown, the locking mechanism includes a pair of locking grooves, and the pair of locking grooves are opened inside the locking rod 6. The inside of the pair of locking grooves is slidably connected with a locking block 7, and the end of the locking block 7 away from the locking rod 6 is fixedly connected with a locking plate 8, and a pair of limiting rods 9 pass through the inside of the locking plate 8, and the two ends of the pair of limiting rods 9 are fixedly connected to the inner wall of the recessed block 5, and the end of the locking plate 8 away from the locking rod 6 is fixedly connected to a pair of first springs 10, and the end of the pair of first springs 10 away from the locking plate 8 is fixedly connected to the inner wall of the recessed block 5.

[0029] When the second positioning inner ring 2 moves downward, it drives the card rod 6 to move downward. When the card rod 6 moves downward, it will squeeze the inclined surface of the card block 7 under its own gravity. The inclined surface of the card block 7 is forced to drive the card plate 8 to move along the limit rod 9. During the movement, the card plate 8 simultaneously squeezes the first spring 10, causing the first spring 10 to deform and generate elastic potential energy. When the slot inside the card rod 6 and the card block 7 are in the same horizontal plane, the squeezing of the card rod 6 on the card block 7 ends, and the first spring 10 instantly releases the elastic potential energy, and pushes the card block 7 to reset through the card plate 8. When the card block 7 is reset, it will be engaged in the internal slot of the card rod 6, thereby limiting the card rod 6. The card rod 6 cannot move at this time, thereby quickly limiting the first positioning inner ring 1 and the second positioning inner ring 2, thereby facilitating subsequent welding work.

[0030] like Figure 1 and Figure 2 As shown, the engaging mechanisms are provided in six groups, and the six groups of engaging mechanisms are arranged in a circular array on the inner sides of the first positioning inner ring 1 and the second positioning inner ring 2 .

[0031] Six groups of engaging mechanisms are provided, which can quickly limit the three groups of first positioning inner rings 1 and second positioning inner rings 2, which is more convenient and quick.

[0032] like Figure 3 and Figure 4 As shown, the end of the card plate 8 facing away from the card block 7 is fixedly connected to the first electromagnetic plate 11, and the inner wall of the recessed block 5 is fixedly connected to the second electromagnetic plate 12. The first electromagnetic plate 11 and the second electromagnetic plate 12 are electrically connected to an external controller, and the external controller is used to control the start and stop of the first electromagnetic plate 11 and the second electromagnetic plate 12.

[0033] When the card block 7 needs to be disengaged from the card slot inside the card rod 6, the staff only needs to control the external controller. The external controller then controls the second electromagnetic plate 12 and the first electromagnetic plate 11 to be energized. The second electromagnetic plate 12 exerts an attractive force on the first electromagnetic plate 11, and the first electromagnetic plate 11 will drive the card block 7 to disengage from the card slot inside the card rod 6 through the card plate 8, thereby ending the limiting of the card block 7 on the card rod 6.

[0034] like Figure 3 and Figure 5 As shown, a fixing plate 13 is fixedly connected to the inner wall of the recessed block 5, and an inclined block 14 is fixedly connected to the top end of the fixing plate 13. The inclined block 14 is designed in a "right triangle".

[0035] When the crane is placing the second positioning inner ring 2, there may be a slight deviation in the position, which causes the clamping rod 6 to be unable to accurately fall into the designated recessed block 5. When the clamping rod 6 deviates, the clamping rod 6 will contact the inclined surface of the inclined block 14, and with the gravity of the clamping rod 6, the clamping rod 6 will slide downward along the inclined surface of the inclined block 14, and the bottom of the inclined surface of the inclined block 14 is the designated engaging area. The clamping rod 6 will eventually fall into the designated area along the inclined surface of the inclined block 14, thereby improving the stability when hoisting the second positioning inner ring 2.

[0036] like Figure 6 and Figure 7 As shown, the inner walls of the first positioning inner ring 1 and the second positioning inner ring 2 are fixedly connected with connecting blocks 15, and a pair of the connecting blocks 15 are connected by bolts. The insides of the first positioning inner ring 1 and the second positioning inner ring 2 are provided with limiting grooves 16, and the limiting grooves 16 are "L-shaped" in design. The inside of the limiting grooves 16 is provided with anti-rust mechanisms, and the anti-rust mechanisms are used to prevent the connecting blocks 15 from rusting.

[0037] When welding the first positioning inner ring 1 and the second positioning inner ring 2, it is necessary to connect the connecting blocks 15 on the inner sides of the first positioning inner ring 1 and the second positioning inner ring 2 together by bolts to play a double fixing function. Then, the connecting blocks 15 are prone to rust in rainy and snowy weather, which in turn affects the service life of the connecting blocks 15. In order to solve the above problem, when this embodiment is used, the anti-rust mechanism is slidably connected to the inside of the limiting groove 16, thereby protecting the outside of the connecting block 15 and isolating rain and snow from the outside of the anti-rust mechanism, thereby avoiding rain and snow from contacting the connecting block 15, thereby solving the rust problem of the connecting block 15 caused by rain and snow, increasing the service life of the connecting block 15, and improving safety.

[0038] like Figure 6 and Figure 7 As shown, the anti-rust mechanism includes a first baffle 17 and a second baffle 18, the first baffle 17 and the second baffle 18 are of "Z-shaped" design, the first baffle 17 and the second baffle 18 are both slidably connected inside the limiting groove 16, one end of the first baffle 17 close to the second baffle 18 is slidably connected inside the second baffle 18, a pair of second springs 19 are fixed between the first baffle 17 and the second baffle 18, and a pair of partitions 20 pass through the first baffle 17 and the second baffle 18.

[0039] When installing the first baffle 17 and the second baffle 18, first move the first baffle 17 and the second baffle 18 in opposite directions. When moving, the first baffle 17 and the second baffle 18 move along the outer side of the partition 20 and squeeze the second spring 19, so that the second spring 19 is deformed and generates elastic potential energy. Then, align the first baffle 17 and the second baffle 18 with the limiting groove 16 and place them at the top of the limiting groove 16. Since the limiting groove 16 is designed in an "L" shape, the first baffle 17 The first baffle plate 17 and the second baffle plate 18 are designed in a "Z" shape. At this time, the first baffle plate 17 and the second baffle plate 18 are loosened, the force on the second spring 19 stops, and the elastic potential energy is released instantly. The "Z"-shaped apex of the first baffle plate 17 and the second baffle plate 18 is just engaged inside the "L"-shaped apex of the limiting groove 16, thereby limiting the first baffle plate 17 and the second baffle plate 18. The first baffle plate 17, the second baffle plate 18 and the partition plate 20 will cooperate to wrap the connecting block 15, thereby preventing rain and snow from contacting the connecting block 15.

[0040] like Figure 1 , Figure 2 and Figure 7 As shown, the anti-rust mechanism is provided in six groups, and the six groups of anti-rust mechanisms are arranged in a circular array on the inner walls of the first positioning inner ring 1 and the second positioning inner ring 2 .

[0041] Six groups of rust-proof mechanisms are provided, which can protect the connection blocks 15 on the inner walls of the three groups of first positioning inner rings 1 and the three groups of second positioning inner rings 2, so that the protection is more comprehensive.

[0042] Working principle: In the past, the supporting tire frame required radially arranged rows of concrete piers, each row of concrete piers included at least two radially aligned piers, and multiple rows of concrete piers were arranged at intervals along the circumferential direction, and finally supported the annular structure in the initial state, and the supporting tire frame required on-site construction of piers, and each row of piers needed to be marked and aligned for construction. The process was relatively cumbersome, requiring the staff to have professional skills, and was relatively time-consuming and labor-intensive. In order to solve the above problems, when this embodiment is used, first, multiple groups of first positioning inner rings 1 and second positioning inner rings 2 are welded to the positioning outer ring 3 through radial connecting rods 4 to form multiple integral parts, which are transported to the construction site, and the first positioning inner ring 1 is placed in the area where construction is required. At this time, the second positioning inner ring 2 is lifted by a crane, and the second positioning inner ring 2 is The edge is aligned with the edge of the first positioning inner ring 1 and is lowered vertically. During the movement of the second positioning inner ring 2, the clamping rod 6 is driven to move vertically downward. During the downward movement, the clamping rod 6 squeezes the locking mechanism, and the locking mechanism moves under force. When the clamping rod 6 accurately falls into the interior of the concave block 5, the locking mechanism is reset to fix the position of the clamping rod 6. At this time, the clamping rod 6 cannot move, thereby limiting the first positioning inner ring 1 and the second positioning inner ring 2. Subsequently, in the subsequent welding process of the first positioning inner ring 1 and the second positioning inner ring 2, the first positioning inner ring 1 and the second positioning inner ring 2 cannot shake, thereby achieving a stable effect and solving the troublesome problem of needing to construct piers on site. The above-mentioned splicing method is more convenient for installation. It also facilitates transportation to a certain extent. Finally, the remaining two groups of first positioning inner ring 1 and second positioning inner ring 2 are assembled through the above-mentioned installation to form a supporting tire frame. When the second positioning inner ring 2 moves downward, it drives the card rod 6 to move downward. The card rod 6 moves downward and squeezes the inclined surface of the card block 7 under its own gravity. The inclined surface of the card block 7 is forced to drive the card plate 8 to move along the limit rod 9. The card plate 8 squeezes the first spring 10 during the movement, causing the first spring 10 to deform and generate elastic potential energy. When the card groove inside the card rod 6 and the card block 7 are in the same horizontal plane, the card rod 6 ends squeezing the card block 7, and the first spring 10 instantly releases the elastic potential energy, pushing the card block 7 to reset through the card plate 8. The reset of the card block 7 will jam The clamping mechanism is provided with six groups, which can quickly limit the three groups of first positioning inner rings 1 and second positioning inner rings 2, which is more convenient and quicker. When the clamping block 7 needs to be disengaged from the clamping slot inside the clamping rod 6, the staff only needs to control the external controller. The external controller controls the second electromagnetic plate 12 and the first electromagnetic plate 11 to be energized. The second electromagnetic plate 12 exerts attraction on the first electromagnetic plate 11, and the first electromagnetic plate 11 drives the clamping block 7 to disengage from the clamping slot inside the clamping rod 6 through the clamping plate 8, thereby ending the limiting of the clamping block 7 on the clamping rod 6.When the crane places the second positioning inner ring 2, there may be a slight deviation in the position, which causes the clamping rod 6 to be unable to accurately fall into the designated concave block 5. When the clamping rod 6 deviates, the clamping rod 6 will contact the inclined surface of the inclined block 14, and with the gravity of the clamping rod 6, the clamping rod 6 will slide downward along the inclined surface of the inclined block 14, and the bottom of the inclined surface of the inclined block 14 is the designated engaging area. The clamping rod 6 will eventually fall into the designated area along the inclined surface of the inclined block 14, thereby improving the stability when hoisting the second positioning inner ring 2. When welding the first positioning inner ring 1 and the second positioning inner ring 2, it is necessary to use bolts to The connecting blocks 15 on the inner sides of the first positioning inner ring 1 and the second positioning inner ring 2 are connected together to play a dual fixing function. Then, the connecting blocks 15 are prone to rust in rainy and snowy weather, which in turn affects the service life of the connecting blocks 15. In order to solve the above problem, when in use, the present embodiment slides the anti-rust mechanism inside the limiting groove 16, thereby protecting the outer side of the connecting block 15 and isolating rain and snow from the outside of the anti-rust mechanism, thereby preventing rain and snow from contacting the connecting blocks 15, thereby solving the rust problem of the connecting blocks 15 caused by rain and snow, increasing the service life of the connecting blocks 15, and improving In order to improve safety, when installing the first baffle 17 and the second baffle 18, first move the first baffle 17 and the second baffle 18 in opposite directions. When moving, the first baffle 17 and the second baffle 18 move along the outer side of the partition 20 and squeeze the second spring 19, so that the second spring 19 is deformed and generates elastic potential energy. Then, align the first baffle 17 and the second baffle 18 with the limiting groove 16 and place them at the top of the limiting groove 16. Since the limiting groove 16 is designed in an "L" shape and the first baffle 17 and the second baffle 18 are designed in a "Z" shape, at this time, release the first baffle 17 and When the second baffle 18 and the second spring 19 are no longer stressed, the elastic potential energy is released instantly. The "Z"-shaped vertices of the first baffle 17 and the second baffle 18 are just engaged inside the "L"-shaped vertices of the limiting groove 16, thereby limiting the first baffle 17 and the second baffle 18. The first baffle 17, the second baffle 18 and the partition 20 cooperate to wrap the connecting block 15, thereby preventing rain and snow from contacting the connecting block 15. The anti-rust mechanism is provided with six groups, which can protect the connecting blocks 15 on the inner walls of the three groups of first positioning inner rings 1 and the three groups of second positioning inner rings 2, and the protection is more comprehensive.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
