[0010] Based on the structure of the arch frame transfer system described above, the support trolley includes a first guide wheel, a second guide wheel, a top guide wheel, and a support body.

[0017] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims and abstract) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a predetermined orientation, or be constructed and operated in a predetermined orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0021] Example 1 like Figures 1-7 As shown, this utility model provides a technical solution: An arch frame transfer system includes, but is not limited to, a hoisting mechanism 1, a transfer mechanism 2, a storage rack 3, and a platform 4. The hoisting mechanism 1 is capable of moving away from or towards the working face in at least a portion of the area of ​​the platform 4. The hoisting mechanism 1 is also equipped with a pitch adjustment assembly 5 and a swing assembly 6. Under the action of the pitch adjustment assembly 5 and the swing assembly 6, the hoisting mechanism can perform pitch and lateral swing operations. The transfer mechanism 2 is equipped with a support trolley 23 that can move along the length of the platform 4. The support trolley 23 is equipped with a lifting assembly. The hoisting mechanism 1, in conjunction with the lifting assembly, can transfer the arch frame 7 to be transported to a predetermined position on the storage rack 3 for storage.

[0022] Based on the above structure, this solution uses a hoisting mechanism 1 to hoist the arch frame 7. The hoisting mechanism 1 itself is equipped with a pitch adjustment assembly 5 and a swing assembly 6, enabling it to adjust the pitch and yaw of the hoisted arch frame 7. This ensures the arch frame 7 can cooperate with the transfer mechanism 2 in the correct posture, facilitating its transfer. During transfer, a lifting assembly elevates the support trolley 23, ensuring the arch frame 7 on the support trolley 23 avoids interference with the hoisting mechanism 1 and the storage rack 3, allowing the arch frame 7 to be transported smoothly on the platform 4. When the trolley 23 transports the arch frame 7 to the designated position, it places the arch frame 7 on the storage rack 3, supporting the trolley 23 to return to the initial position for the next arch frame 7 transfer operation. This solution solves the efficiency and safety issues of segmented arch frame 7 during transfer. Compared with other arch frame 7 transfer solutions, this solution uses a hoisting method to ensure the stability and safety of the arch frame 7 during the lifting process. The transfer of the arch frame 7 does not affect the parallel operation of other processes, and the arch frame 7 is stored on the platform 4 in advance before the arch is erected, which greatly shortens the preparation time for the arch erection and greatly improves the overall construction efficiency of the machine.

[0023] As an example, a support slide rail 41 that cooperates with the hoisting mechanism is provided on the platform 4, and a sliding trolley 11 that cooperates with the support slide rail 41 is provided at the bottom of the hoisting mechanism 1. The hoisting mechanism 1 moves under the cooperation of the sliding trolley 11 and the support slide rail 41.

[0024] The hoisting mechanism 1 may include a power unit 12, a support boom 13, and a support base 14. The support base 14 is mounted on the sliding trolley 11 and is connected to an auxiliary support 16 via a pitch adjustment assembly. At least one swing assembly 6 is mounted on the auxiliary support 16 and connected to the support boom 13. The power unit 12 is mounted on the support boom 13 and is equipped with a hook 15. The hook 15 can drive the arch frame 7 to perform lifting operations under the action of the power unit 12.

[0025] Based on the above structure, the entire support arm 13 is fixed on the sliding trolley 11 by the support base 14, and the pitch adjustment of the support arm 13 is realized by the pitch adjustment component, and the swing adjustment of the support arm 13 is realized by the swing component 6, making the adjustment of the support arm 13 more flexible.

[0026] As an example, the pitch adjustment assembly can be a pitch cylinder, with the cylinder body of the pitch cylinder hinged to the support base 14 and the piston rod of the pitch cylinder hinged to the auxiliary support 16. The auxiliary support 16 includes a first end 161, a second end 162, and a third end 163. The first end 161 is hinged to the piston rod of the pitch cylinder, and the second end 162 is hinged to the top of the support base 14. The third end 163 is provided with a hinge lug 164, and one end of the support arm 13 is hinged to the third end 163 through the hinge lug 164. The swing assembly 6 can be a swing cylinder. The cylinder body of the swing cylinder is hinged to the side wall of the auxiliary support 16, and the piston part of the swing cylinder is hinged to the side wall of the support arm 13.

[0027] Based on the above structure, since the base and piston rod of the pitch cylinder are hinged to the first end 161 of the support base 14 and the auxiliary support 16 respectively, and the second end 162 of the auxiliary support 16 is hinged to the top position of the support base 14, the pitch adjustment of the entire auxiliary base can be realized by the action of the pitch cylinder, and the pitch adjustment of the support arm 13 hinged thereon can be achieved; at the same time, the action of the pitch cylinder in this scheme can make the support arm 13 rotate relative to the hinge ear 164, realizing the left and right swing adjustment, thus realizing the adjustment of the support arm 13.

[0028] As an example, the power unit 12 can be a winch assembly; a fixed pulley 17 is provided at the end of the supporting boom 13 away from the auxiliary support 16; the winch assembly is connected to the hook 15 by passing a steel rope 18 through the fixed pulley 17.

[0029] Based on the above structure, the arch frame 7 is hoisted by the extension and retraction of the hook 15, and the arch frame 7 is transferred in conjunction with the sliding trolley 11. Using the hook 15 to hoist the arch frame 7 can effectively reduce the difficulty of hoisting and improve the hoisting efficiency.

[0030] As an example, the transfer mechanism 2 may include a support rail 21, a drive assembly 22, and a support trolley 23; track grooves 211 are provided on both sides of the support rail 21; the bottom of the support rail 21 is connected to the top of the platform 4 through a support column 213; support wheel sets 212 are provided at both ends of the support rail 21; the drive assembly 22 is connected to the support trolley 23 through a transmission chain 214; the support column 213 is provided with a through hole for the transmission chain 214 to pass through; the transmission chain 214 is arranged around the circumferential position of the support rail. The support trolley 23 can include a first guide wheel 231, a second guide wheel 232, a top guide wheel 233, and a support body 234. The first guide wheel 231 and the second guide wheel 232 are connected to the support body 234. The first guide wheel 231 and the second guide wheel 232 are respectively inserted into the track grooves 211 on both sides of the support track 21. The top guide wheel 233 is located at the end of the support body 234 and contacts the top plane of the support track 21. The lifting assembly is connected to the inner wall of the support body 234.

[0031] Based on the above structure, in this solution, the drive assembly 22 can drive the entire transmission chain 214 to transmit power. Since the support trolley 23 is guided on both sides by the first guide wheel 231 and the second guide wheel 232 on both sides, and rolls in contact with the top guide wheel 233 at the top of the support track 21, the support trolley 23 can smoothly roll and slide in the predetermined direction during transmission, ensuring that the arch frame 7 carried by the lifting assembly can be stably transferred. At the same time, since this solution is equipped with a lifting assembly, the hoisting mechanism does not need to hoist the arch frame too high to complete the transfer of the arch frame. After the lifting mechanism is fixed with the arch frame, it can automatically lift to a position higher than the storage rack 3. This not only reduces the overall manufacturing cost by eliminating the need for an excessively long hoisting mechanism, but also makes the entire arch frame transfer process more flexible and improves the transfer efficiency.

[0032] As an example, a support seat 235 is provided on the inner side wall of the support body 234. The lifting assembly is connected to the support body 234 through the support seat 235. The lifting assembly may include a lifting cylinder 236 and a clamping assembly 237. The cylinder body of the lifting cylinder 236 is fixedly connected to the support seat 235, and the piston part of the lifting cylinder 236 is connected to the clamping assembly 237.

[0033] Based on the above structure, the clamping component 237 of this solution clamps the arch frame 7, and the clamping component 237 can be raised and lowered by the action of the lifting cylinder 236. When the lifting component raises and lowers the arch frame 7, it avoids the hoisting mechanism 1 on the one hand, and also avoids the storage rack 3 on the other hand, so as to achieve efficient transfer of the arch frame 7.

[0034] As an example, the storage rack 3 can be an arch frame 7 support frame, which is respectively set on both sides of the platform 4; the coverage area of ​​the support rail 21 is not less than the coverage area of ​​the arch frame 7 support frame; the horizontal height of the support rail 21 is not higher than the horizontal height of the arch frame 7 support frame.

[0035] Based on the above structure, the arch frame 7 can be stored through the arch frame 7 support frame. The transfer mechanism 2 moves the arch frame 7 to the predetermined position of the arch frame 7 support frame for storage, so that the subsequent arch erection operation can be carried out efficiently.

[0036] As an example, the clamping assembly 237 may include a clamping cylinder 238, a sliding support 239, a fixed support 240, and a support frame 241; the top of the support frame 241 is provided with an open sliding groove 242; and the support frame 241 is hollow inside, the clamping cylinder 238 is hinged inside the support frame 241, the fixed support 240 is located on the top of the support frame 241, and the end of the sliding support 239 is hinged to the piston rod of the clamping cylinder 238; by the action of the clamping cylinder 238, the sliding support 239 is moved away from or closer to the fixed support 240.

[0037] Based on the above structure, when it is necessary to clamp the arch frame 7, the clamping cylinder 238 is activated to move the sliding support 239 to a predetermined position, so that the fixed support 240 and the sliding support 239 simultaneously come into contact with the arch frame 7, thereby achieving stable support and ensuring the stability of the arch frame 7 during transportation and lifting.

[0038] As an example, the cavity structure of the inner frame of the support frame 241 is matched with the bottom shape of the sliding support 239, so that the sliding support 239 can be stably slid in the support frame 241.

[0039] Example 2 This utility model provides a technical solution: A method for transporting and storing arch frames, comprising at least the following steps: Step 1, Lifting: First, the arch frame 7 behind the platform is lifted using the hook 15 of the lifting mechanism 1. Then, the support boom 13 is adjusted using the pitch adjustment assembly 5 and the swing assembly 6 according to actual site requirements to adjust the posture of the arch frame 7 during lifting. It should be noted that before lifting, the arch frame 7 may be located on the ground behind the platform or on a transport vehicle behind the platform. After lifting, the hoisting mechanism moves the hoisted arch frame 7 a predetermined distance towards the transfer mechanism 2, bringing the arch frame 7 into the coverage area of ​​the transfer mechanism. Simultaneously, the support trolley 23 of the transfer mechanism 2 is activated, moving it to the position where the hoisting mechanism will place the arch frame. The hoisting mechanism then lifts the arch frame 7 onto the support trolley 23 and clamps it using the upper clamping assembly 237. It is important to note that the lifting assembly should be lowered to its lowest position before the hoisting mechanism lifts and places the arch frame.

[0040] Step two, transfer: The arch frame 7 is lifted to a height exceeding that of the storage rack 3 using the lifting assembly, and then transported to the predetermined location using the support trolley 23. Step 3, storage: After the support trolley 23 transports the arch frame 7 to the predetermined position, the height of the arch frame 7 is lowered by the lifting component until it reaches the storage rack 3, thus storing the arch frame 7. Step 4: Repeat steps 1 through 3 as needed until the transfer of arch frame 7 is completed.

[0041] In this design, a sliding support boom 13 is installed above the platform 4. The support boom 13 can tilt and sway left and right, which can be used to adjust the posture of the arch frame 7 during the lifting process. A winch is installed on the support boom 13 for lifting the segmented arch frames 7. A transfer mechanism 2 is symmetrically arranged on both sides above the platform 4. The transfer mechanism 2 includes a sliding transfer trolley assembly. The trolley assembly is equipped with a lifting mechanism, which can be used to adjust the lifting height of the arch frame 7. At the same time, a clamping structure is provided on the lifting mechanism. One end of the clamping structure is fixed, and the other end is movable and adjustable to accommodate arch frames 7 of different widths. This ensures that the arch frame 7 does not sway during sliding, guaranteeing stability and safety during transportation. A support frame for storing arch frames 7 is symmetrically arranged on the outermost side of the platform 4. This support frame stores the segmented arch frames 7. After the support boom 13 lifts the arch frame 7 to a predetermined height, the support boom 13 slides back and forth to transport the arch frame 7 to the lifting mechanism of the transfer mechanism 2. Then, a clamping structure clamps both ends of the arch frame 7. The lifting mechanism then lifts the arch frame 7 to the predetermined height again, and the support trolley 23 of the transfer mechanism 2 transports the segmented arch frames 7 to the front end of the platform 4. The lifting mechanism then lowers until both arch frames 7 are completely on the support frame before releasing the clamping cylinders 238. Finally, the support trolley 23 on the transfer mechanism 2 returns to the rear end of the platform 4. By repeating the above steps, all the required arch frames 7 can be transferred to the support frame above the platform 4.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
