[0001] This utility model relates to the field of support frame technology, and more specifically, to a stable support frame for pile foundation construction. Background Technology

[0002] During pile foundation construction, in order to prevent the steel cage from deforming during transportation, a support frame is usually added inside the reinforcing bars for reinforcement.

[0003] In existing technologies, threaded steel bars are typically welded and supported within a reinforcing cage. During on-site hoisting of the reinforcing cage, the support frame is dismantled using gas cutting. However, gas cutting increases equipment investment and material consumption, resulting in high costs and hindering the reuse of the support frame. Therefore, we propose an improvement: a stable support frame for pile foundation construction. Summary of the Invention

[0004] The purpose of this invention is to address the problem that the existing support frame requires gas cutting, which results in high costs.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] For the embodiment, please refer to Figures 1-5. A stable support frame for pile foundation construction includes a support ring 1 with a plurality of mounting holes 101 on the support ring 1. Each mounting hole 101 is provided with a support structure 2. Both sides of the support ring 1 are connected to a bearing frame 102. A rotating shaft 103 is rotatably connected between two bearing frames 102. A first bevel gear 104 located inside the support ring 1 is fixedly connected to the outer surface of the rotating shaft 103.

[0032] The support structure 2 includes a connecting pipe 201 installed at the mounting port 101. A threaded rod 202 is provided inside the connecting pipe 201. One end of the threaded rod 202 extends into the support ring 1 and is fixedly connected to a second bevel gear 203. The second bevel gear 203 meshes with a first bevel gear 104. A telescopic component is provided between the connecting pipe 201 and the threaded rod 202. The first bevel gear 104 drives the second bevel gear 203 to rotate. When the second bevel gear 203 rotates, it can drive the telescopic component to extend and retract. When the telescopic component extends, it is locked inside the reinforcing cage to support the reinforcing cage. When the telescopic component retracts, it can separate from the reinforcing cage, which facilitates the connection and separation of this application from the reinforcing cage without the need for cutting. This application is reusable. Due to the telescopic characteristic of the telescopic component, the versatility of this application can be improved. Moreover, the cooperation between the first bevel gear 104 and the second bevel gear 203 can realize the synchronous action of the telescopic component, making operation convenient.

[0033] Furthermore, the telescopic component includes a connecting rod 204 that is inserted into the connecting tube 201. The connecting rod 204 has a threaded groove 205 in the middle. The inner wall of the threaded groove 205 is threadedly connected to the outer surface of the threaded rod 202. During the rotation of the threaded rod 202, it can drive the connecting rod 204 to move by cooperating with the threaded groove 205, so that the connecting rod 204 extends out of the connecting tube 201 or retracts into the connecting tube 201. Both the connecting rod 204 and the connecting tube 201 are non-circular, and the connecting rod 204 will not rotate.

[0034] Furthermore, the end of the connecting rod 204 away from the second bevel gear 203 extends out of the connecting pipe 201 and is fixedly connected to a locking block 206. The side of the locking block 206 away from the connecting rod 204 has a locking groove 207, which facilitates engagement with the reinforcing bars on the reinforcing cage to improve the stability of the connection between the present application and the reinforcing cage.

[0035] Furthermore, the outer surface of the connecting pipe 201 is inserted into the inner wall of the mounting port 101. The side of the connecting pipe 201 is provided with a threaded hole, and the support ring 1 is provided with a through hole communicating with the mounting port 101. A fastening bolt 208 is inserted and connected to the through hole. One end of the fastening bolt 208 is threadedly connected to the threaded hole. After unscrewing the fastening bolt 208, the connecting pipe 201 can be removed from the support ring 1 for replacement if the support structure 2 is damaged. During installation, align the teeth of the second bevel gear 203 with the first bevel gear 104, insert the connecting pipe 201 into the mounting port 101 so that the first bevel gear 104 meshes with the second bevel gear 203, and then tighten the fastening bolt 208 to fix the position of the connecting pipe 201.

[0036] Furthermore, a bearing is provided at the connection between the outer surface of the threaded rod 202 and the connecting pipe 201, and the bearing is used to realize the connection between the connecting pipe 201 and the threaded rod 202.

[0037] Furthermore, the support frame 102 is welded to the inner side of the support ring 1, and a bearing is provided between the support frame 102 and the outer surface of the rotating shaft 103, so that the support frame 102 can support the rotating shaft 103.

[0038] Furthermore, one end of the rotating shaft 103 extends to the outside of the support ring 1, and the end of the rotating shaft 103 located outside the support ring 1 is connected to an adjustment structure 3. The adjustment structure 3 is used to assist in rotating the rotating shaft 103, and the adjustment structure 3 is also used to lock the rotating shaft 103.

[0039] Furthermore, the adjustment structure 3 includes a worm wheel 304 connected to the rotating shaft 103. The worm wheel 304 is connected to a worm 302. The worm wheel 304 can be driven to rotate by the worm 302. The helix angle of the worm 302 is smaller than the friction angle. By utilizing the self-locking characteristics of the transmission between the worm wheel 304 and the worm 302, the rotating shaft 103 is prevented from rotating in the opposite direction when there is no external force driving it, thereby achieving position locking.

[0040] Furthermore, the outer surface of the worm 302 is connected to two support plates 301 via bearings. Both support plates 301 are welded to the side of the support ring 1, and the support plates 301 can support the worm 302.

[0041] Furthermore, a handwheel 303 is connected to one end of the worm gear 302, and the handwheel 303 is designed to facilitate manual rotation of the worm gear 302.

[0042] The usage process of the stable support frame for pile foundation construction provided by this utility model is as follows:

[0043] Place this application inside the reinforcing cage, turn the handwheel 303, the handwheel 303 drives the worm gear 302 to rotate, the worm gear 302 drives the rotating shaft 103 to rotate through the worm wheel 304, the rotating shaft 103 drives the second bevel gear 203 to rotate through the first bevel gear 104, the second bevel gear 203 drives the threaded rod 202 to rotate, so that the connecting rod 204 extends, the connecting rod 204 drives the locking block 206 to move closer to the reinforcing bars in the reinforcing cage, so that the inner wall of the locking groove 207 engages with the reinforcing bars;

[0044] When it is necessary to remove this application, turn the handwheel 303 in the reverse direction. The handwheel 303 drives the worm gear 302 to rotate. During the rotation of the worm gear 302, the rotating shaft 103 is driven to rotate through the worm wheel 304. The rotating shaft 103 drives the second bevel gear 203 to rotate through the first bevel gear 104. The second bevel gear 203 drives the threaded rod 202 to rotate, causing the connecting rod 204 to retract into the connecting tube 201, so that the inner wall of the slot 207 is separated from the steel bar. Pulling this application outward can remove this application from the steel cage.
