[0001] This utility model relates to the field of ladder cage door technology, specifically to a detachable ultra-high bridge pier device. Background Technology

[0002] The safety protection frame ladder cage for the construction of ultra-high bridge piers is a safety protection device used to ensure the safety of workers on the construction site during the construction of ultra-high bridge piers. Multiple ladder cages are stacked to reach a suitable height, which facilitates workers to move up and down in the foundation pit of the ultra-high bridge pier. At the same time, the side nets on the outside of the ladder cage protect the workers, making their movement safer.

[0003] The existing safety protection frame ladder cages used for the construction of ultra-high bridge piers are installed by stacking bolts through the splicing joints and then locking them with nuts. This makes the splicing process cumbersome and affects the construction progress. In addition, the bolts need to be removed separately during the later disassembly, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a detachable ultra-high bridge pier device to solve the problem that when the safety protection ladder cage used for the construction of ultra-high bridge piers is stacked and spliced, it is necessary to use multiple screws and nuts for locking, which makes the disassembly and assembly cumbersome and affects the construction process.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a detachable ultra-high bridge pier device, including a protective ladder cage, a ladder inside the protective ladder cage, a door frame on the side of the protective ladder cage, a protective door rotatably connected to the inner side of the door frame by a hinge, a connecting mechanism between two adjacent protective ladder cages, and an automatic closing mechanism between the protective door and the protective cage.

[0006] The connecting mechanism includes a splicing top cylinder at the top of the protective ladder cage and a splicing bottom column at the bottom of the protective ladder cage. One end of the splicing bottom column is inserted into the splicing top cylinder to connect two adjacent protective ladder cages.

[0007] The automatic door closing mechanism includes a mounting rod located at the top front end of the protective door and an end post located on the surface of the protective ladder cage. A tension spring connects the end post and the mounting rod.

[0008] Furthermore, the side wall of the splicing top cylinder is provided with a locking hole, and the outer periphery of the splicing bottom column is provided with a locking block. One end of the locking block extends into the locking hole and is movably connected to the locking hole.

[0009] Furthermore, there are two or more card holes and card blocks, and the bottom of the card block is provided with an inclined surface, which is used to insert the card block into the card hole.

[0010] Furthermore, the lower part of the splicing base column is provided with several elastic plates, and the locking block is fixed on the elastic plates.

[0011] Furthermore, a compression collar is fitted around the outer periphery of the splicing top cylinder, and the splicing top cylinder is threadedly connected to the compression collar. The compression collar is rotated through the thread to cover the card hole.

[0012] Furthermore, the ladder surface is provided with uprights, and handrails are fixed on the uprights.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This utility model uses a splicing base column, a splicing top cylinder, a locking block, and an elastic sheet. The splicing base column is inserted into the splicing top cylinder, which enables the upper and lower protective ladder cages to be installed and fixed quickly, improving construction efficiency. By squeezing the collar as it moves upward on the splicing top cylinder, the locking block is squeezed and pushed out of the locking hole, achieving rapid disassembly and separation.

[0022] 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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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. Example

[0023] like Figure 1-5 As shown, a detachable ultra-high bridge pier device includes a protective ladder cage 1. The protective ladder cage 1 has an internal ladder with uprights on its surface and handrails fixed to the uprights. A door frame is provided on the side of the protective ladder cage 1, and a protective door 2 is rotatably connected to the inside of the door frame via hinges. A connecting mechanism is provided between two adjacent protective ladder cages 1, and an automatic closing mechanism is provided between the protective door 2 and the protective ladder cage 1.

[0024] The connecting mechanism includes a splicing top cylinder 4 at the top of the protective ladder cage 1 and a splicing bottom column 3 at the bottom of the protective ladder cage 1. One end of the splicing bottom column 3 is inserted into the splicing top cylinder 4 to connect two adjacent protective ladder cages 1. The side wall of the splicing top cylinder 4 has a locking hole 6, and the outer periphery of the splicing bottom column 3 has a locking block 5. One end of the locking block 5 extends into the locking hole 6 and is movably connected to it. There are two or more locking holes 6 and locking blocks 5. The bottom of the locking block 5 has an inclined surface for engaging the locking block 5 into the locking hole 6. The lower part of the splicing bottom column 3 has several elastic plates 7, and the locking block 5 is fixed to the elastic plates 7. A compression collar 8 is fitted onto the outer periphery of the splicing top cylinder 4. The splicing top cylinder 4 is threadedly connected to the compression collar 8, and the compression collar 8 rotates through the thread to cover the locking hole 6. The top wall of the locking hole 6 has an inclined surface for easy disengagement of the locking block 5.

[0025] The automatic closing mechanism includes a mounting rod 9 located at the top front end of the protective door 2 and an end post 11 located on the surface of the protective cage 1. A tension spring 10 is connected between the end post and the mounting rod. The tension spring 10 is installed on the protective door 2 and the cage 1 via the end post 11 and the mounting rod 9. After the protective door is opened, the tension spring 10, which is in a stretched state, returns to its original deformation, thereby applying elastic traction to the protective door 2, causing the protective door to quickly move back and close. This effectively prevents safety accidents caused by the protective door not being closed and improves the safety of this application.

[0026] Working principle:

[0027] When stacking and fixing the protective ladder cage 1, the splicing bottom post 3 is inserted into the splicing top cylinder 4. The bottom slope of the locking block 5 is squeezed and slides inward, squeezing the elastic plate 7 and the locking block 5 into the splicing top cylinder 4. The splicing bottom post 3 is fully inserted into the splicing top cylinder 4. When the locking block 5 moves down to the locking hole 6, the locking block 5 is locked in the locking hole 6 and extends to the outside of the locking hole, realizing the stacking and assembly of the protective ladder cage 1. The stacking of the protective ladder cage 1 is then disassembled. The squeezing collar 8 is rotated, and the squeezing collar 8 moves upward along the outer wall of the splicing top cylinder 4, thereby squeezing the locking block 5 to move into the locking hole 6. When the squeezing collar 8 completely covers the locking hole, the splicing bottom post 3 is pulled upward, and the locking block 5 disengages along the slope of the top wall of the locking hole 6. The disassembly of the protective ladder cage 1 is completed. The squeezing collar 8 is rotated downward, and the squeezing collar 8 is reset.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
