[0030] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0031] Example 1

[0032] Please refer to Figures 1-4. The present invention provides an internal support operation platform for a caisson, comprising: a caisson wall 1;

[0033] Horizontal pre-embedded sleeve 2 installed inside the caisson wall 1;

[0034] An inclined embedded sleeve 3 is installed inside the caisson wall 1 and located below the horizontal embedded sleeve 2;

[0035] A horizontal support rod 4 is inserted into the horizontal pre-embedded sleeve 2, and a movable groove is provided at the top of the horizontal support rod 4;

[0036] An inclined support rod 5 is inserted into the inclined pre-embedded sleeve 3, and the inclined support rod 5 is connected to the horizontal support rod 4 by bolts and nuts;

[0037] The extension support rod 6 is slidably engaged in the movable groove. The horizontal support rod 4 is provided with a limiting mechanism for fixing the extension support rod 6. One end of the extension support rod 6 is provided with a through groove.

[0038] Protective railing 7, inserted into the through groove;

[0039] And a limiting ring 8 that is fixedly installed on the surface of the guardrail 7.

[0040] The technical solution provided in this embodiment is as follows: By pre-installing horizontal pre-embedded sleeves 2 and inclined pre-embedded sleeves 3 in the caisson wall 1, when erecting the operating platform, the horizontal support rod 4 is inserted into the horizontal pre-embedded sleeve 2, and the inclined support rod 5 is inserted into the inclined pre-embedded sleeve 3. At the same time, the inclined support rod 5 and the horizontal support rod 4 are connected by fasteners so that the inclined support rod 5 supports the horizontal support rod 4, ensuring the load-bearing performance of the horizontal support rod 4. Then, scaffold boards are erected on the adjacent horizontal support rods 4 to complete the erection and installation of the operating platform. Therefore, the operating platform can be quickly erected and installed. The operation process is simple and quick, which can reduce the installation risk and effectively improve the safety of the operating platform installation and the construction efficiency of the caisson. Then, the guardrail 7 is directly inserted into the through groove and limited by the limiting ring 8. Conversely, the guardrail 7 can be removed by moving it upwards. This achieves the effect of quickly fixing and disassembling the guardrail 7 and avoids the situation where the guardrail 7 is not easy to fix and disassemble.

[0041] Furthermore, the limiting mechanism includes a plurality of limiting holes 9 equally spaced along the length of the horizontal support rod 4, a through hole on the extended support rod 6 that mates with the limiting holes 9, and a limiting pin 10 that is inserted into the through hole and a limiting hole 9.

[0042] Specifically, by moving the limiting pin 10 upward to separate it from the limiting hole 9, the extension support rod 6 can be pulled outward. After moving it to a suitable position, the extension support rod 6 can be fixed by inserting the limiting pin 10 into the limiting hole 9. This makes it easy to adjust the support area of ​​the horizontal support rod 4 according to the needs, thereby facilitating the adjustment of the usable area of ​​the operating platform and improving the flexibility of use.

[0043] Furthermore, the inclined support rod 5 is provided with a support mechanism for supporting the extension support rod 6.

[0044] The support mechanism includes a connecting rod 16 mounted on one side of the inclined support rod 5 by bolts and nuts, a support sleeve 17 movably connected to one end of the connecting rod 16, a movable support rod 18 slidably connected inside the support sleeve 17 and movably connected to the extension support rod 6, a second hand screw 19 threaded through and connected to the support sleeve 17, and a plurality of fixing holes 20 formed on the surface of the movable support rod 18 and mating with the second hand screw 19.

[0045] Specifically, when adjusting the extension support rod 6, the extension support rod 6 can be pulled outwards by rotating the second hand screw 19 to separate it from the fixing hole 20, and then the limitation mechanism will release the restriction on the extension support rod 6. At the same time, the extension support rod 6 will drive the movable support rod 18 to slide out of the support sleeve 17 and rotate the support sleeve 17 to adjust the angle. After the extension support rod 6 is adjusted to a suitable position, it will be fixed by the limitation mechanism, and the second hand screw 19 will be rotated to insert into the corresponding fixing hole 20 to fix the movable support rod 18. Thus, the movable support rod 18 can support the extension support rod 6, which in turn can further support the horizontal support rod 4, which is beneficial to improving the stress stability of the horizontal support rod 4.

[0046] Example 2

[0047] Based on Embodiment 1, in this embodiment: a groove is provided at the top of the extension support rod 6, a slider 11 is slidably engaged in the groove, and a slot block 12 is fixedly installed on the top of the slider 11.

[0048] The technical solution provided in this embodiment is as follows: by setting the slot block 12, the rod can be snapped and fixed so as to place the construction rod. At the same time, by moving the slot block 12, the slider 11 can slide in the groove, and the position of the slot block 12 can be adjusted to improve the flexibility of use.

[0049] Furthermore, the card slot block 12 is provided with a locking mechanism for fixing its position.

[0050] The locking mechanism includes a connecting block 13 fixedly installed on one side of the slot block 12, a hand screw 14 threadedly connected to the connecting block 13, and an abutment block 15 fixedly connected to one end of the hand screw 14.

[0051] Specifically, after the slot block 12 is adjusted, the contact block 15 is moved by turning the hand screw 14, so that the contact block 15 abuts against the horizontal support rod 4 or the extension support rod 6, thereby fixing the position of the slot block 12 to ensure the stability of the construction rod placement. Conversely, the fixed position can be released by turning the hand screw 14 in reverse.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
