Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a safety protection structure for dam construction. Background Technology

[0002] Dam projects, as a crucial component of infrastructure construction, play a vital role in many areas such as water resource utilization, flood control, and power generation. With the continuous expansion of dam construction projects and the increasing complexity of construction technologies, safety issues during dam construction have become increasingly prominent, prompting the continuous development and innovation of safety protection structures for dam construction.

[0003] Protective railings and netting on dam slopes are typically fixed directly to the slope surface. When seismic waves arrive or blasting operations in the vicinity cause vibrations, the rigidly connected protective structures cannot absorb and buffer the energy, and may shake violently along with the slope soil or even collapse entirely. This not only fails to protect the safety of construction workers on the slope, but also causes secondary disasters due to the collapsed protective facilities, such as falling railing components causing impact injuries to personnel and equipment below. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection structure for dam construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a safety protection structure for dam construction, comprising:

[0006] First fixed frame;

[0007] A transmission assembly is placed inside a first fixed frame. The transmission assembly includes a second fixed frame that is slidably connected to the first fixed frame. A first sliding block is slidably connected to the second fixed frame. A second sliding block is fixedly connected to the first sliding block. A transmission rod is fixedly connected to the second sliding block. A lever is fixedly connected to the transmission rod. A damping mechanism is fixedly connected between the second fixed frame and the first fixed frame. A threaded rod is fixedly connected to the first fixed frame.

[0008] A fixing component is fixedly connected to the first fixing frame on the side near the transmission assembly. A rotating shaft is rotatably connected to the fixing component, and the rotating shaft is fixedly connected to the second fixing frame.

[0009] Furthermore, a slot is provided in the second fixed frame, and the first sliding block is slidably connected to the slot in the second fixed frame.

[0010] The above technical solution is adopted: by setting a groove on the second fixed frame, the first sliding block is guided.

[0011] Furthermore, a slot is provided on the side of the second sliding block near the transmission rod, and a round rod is fixedly connected to the transmission rod. The round rod on the transmission rod is slidably connected to the slot on the second sliding block.

[0012] The above technical solution involves setting a slot on the side of the second sliding block near the transmission rod. During use, the round rod on the transmission rod is inserted into the slot to avoid hindering the rotation of the second sliding block.

[0013] Furthermore, the second sliding block has a threaded hole.

[0014] The above technical solution is adopted: by providing a threaded hole on the second sliding block, it is convenient to connect the threaded rod during use.

[0015] Furthermore, the second fixed frame has an opening, and the toggle block is slidably connected to the opening on the second fixed frame.

[0016] The above technical solution is adopted: by opening a hole in the second fixed frame, the push block is guided during use.

[0017] Furthermore, a slot is provided on the side of the first fixed frame near the second fixed frame.

[0018] The above technical solution is adopted: by opening a slot on the first fixed frame, the second fixed frame is prevented from being stuck during use.

[0019] Furthermore, the fastener is threaded with bolts.

[0020] The above technical solution is adopted: by threading bolts on the fastener, it is convenient to fix the fastener to the first fixed frame.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, the operator manually pulls the lever, causing it to shift and synchronously move the transmission rod rigidly connected to it. A round rod fixedly connected to one end of the transmission rod slides within a slot on the side of the second sliding block near the transmission rod. This structure provides a reliable connection for the transmission rod to drive the second sliding block while ensuring no obstruction to its rotation. Driven by the transmission rod, the second sliding block slides along the slot direction within the pre-drilled slot in the second fixed frame, and simultaneously rotates due to its structural characteristics. The first sliding block, fixedly connected to the second sliding block, also slides in coordination under the guidance of the slot in the second fixed frame. This linkage enables the splicing of the two first fixed frames, with each component working closely together, ensuring the efficiency and accuracy of the protective structure installation operation, and solving the problem of existing technologies failing to achieve shock absorption.

[0023] 2. In this utility model, the design of the flip-up second fixed frame cooperating with the rotating shaft, after the upper and lower layers of the second fixed frame are fixed with bolts, forms a simple and effective shock absorption and buffer system. When the transport vehicle encounters bumps and vibrations during the journey, this structure can actively absorb and disperse the vibration energy, avoid the protective components from colliding, rubbing or deforming due to severe vibration, and ensure the integrity of the protective structure transported to the construction site. This greatly reduces the workload of subsequent inspection and debugging before installation, not only saving time and costs, but also helping to quickly and smoothly carry out the construction of dam construction safety protection facilities, and ensuring that the construction process proceeds as planned.

[0033] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] like Figures 1-5 As shown, this utility model provides a technical solution: a safety protection structure for dam construction, comprising:

[0036] First fixed frame 1;

[0037] Transmission assembly 2 is placed inside the first fixed frame 1. The transmission assembly 2 includes a second fixed frame 21 that is slidably connected to the first fixed frame 1. A first sliding block 23 is slidably connected to the second fixed frame 21. A second sliding block 27 is fixedly connected to the first sliding block 23. A transmission rod 24 is fixedly connected to the second sliding block 27. A lever 25 is fixedly connected to the transmission rod 24. A damper 26 is fixedly connected between the second fixed frame 21 and the first fixed frame 1. A threaded rod 22 is fixedly connected to the first fixed frame 1.

[0038] Fixing component 3 is fixedly connected to the first fixing frame 1 on the side near the transmission component 2. A rotating shaft 31 is rotatably connected to the fixing component 3, and the rotating shaft 31 is fixedly connected to the second fixing frame 21.

[0039] In this invention, the operator manually pulls the lever 25, causing it to shift and synchronously move the transmission rod 24, which is rigidly fixed to it. A round rod fixedly connected to one end of the transmission rod 24 slides within a slot on the second sliding block 27 near the transmission rod 24. This structure provides a reliable connection for the transmission rod 24 to drive the second sliding block 27, while ensuring that the rotation of the second sliding block 27 is not hindered. Driven by the transmission rod 24, the second sliding block 27 slides along the slot direction within the pre-opened slot in the second fixed frame 21, and rotates during the sliding process due to its structural characteristics. The first sliding block 23, fixedly connected to the second sliding block 27, also slides in coordination under the guidance of the slot in the second fixed frame 21. This linkage enables the splicing of the two first fixed frames 1. The close cooperation of all components ensures the efficiency and accuracy of the protective structure installation operation and solves the problem that existing technologies cannot achieve shock absorption.

[0040] Furthermore, such as Figures 1 to 5 As shown, a slot is provided in the second fixed frame 21, and the first sliding block 23 is slidably connected to the slot in the second fixed frame 21. By setting the slot in the second fixed frame 21, the first sliding block 23 is guided.

[0041] A slot is provided on the side of the second sliding block 27 near the transmission rod 24. A round rod is fixedly connected to the transmission rod 24. The round rod on the transmission rod 24 is slidably connected to the slot on the second sliding block 27. By providing a slot on the side of the second sliding block 27 near the transmission rod 24, the round rod on the transmission rod 24 can be inserted into the slot during use to avoid hindering the rotation of the second sliding block 27.

[0042] The second sliding block 27 has a threaded hole, which facilitates the connection of the threaded rod 22 during use.

[0043] The second fixed frame 21 has an opening, and the lever 25 is slidably connected to the opening in the second fixed frame 21. The opening in the second fixed frame 21 serves as a guide for the lever 25 during use.

[0044] A slot is provided on the side of the first fixed frame 1 near the second fixed frame 21. By providing a slot on the first fixed frame 1, the second fixed frame 21 is prevented from being stuck during use.

[0045] The fastener 3 is threaded with bolts, which facilitates fixing the fastener 3 to the first fixed frame 1.

[0046] Working principle: such as Figures 1-5 As shown, in use, first install wire mesh on the first fixed frame 1, then advance the two first fixed frames 1 to each other so that the threaded rod 22 on one first fixed frame 1 is close to the second sliding block 27 on the other first fixed frame 1, and then fix one first fixed frame 1 to the dam with bolts.

[0047] The staff directly pulls the lever 25, causing the lever 25 to move the transmission rod 24, which in turn moves the second sliding block 27. The first sliding block 23 slides in the slot in the second fixed frame 21, causing the second sliding block 27 to rotate, thus splicing the two first fixed frames 1. The lever 25 is then fixed to the second fixed frame 21 with bolts, completing the splicing of the two first fixed frames 1.

[0048] By incorporating a pivot 31, the second fixed frame 21 can be flipped during transportation, and bolts can be used to fix the upper and lower layers of the second fixed frame 21, thereby achieving a shock absorption effect during transportation.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
