Description

Technical Field

[0001] This utility model relates to the field of construction safety railing technology, and in particular to safety railings for power construction. Background Technology

[0002] Safety barriers for power construction are fencing facilities specifically designed for power engineering construction sites to protect worker safety, isolate the construction site, and prevent external interference.

[0003] However, existing guardrails have several problems: First, they lack stability. The support structure at the base of some guardrails is poorly designed, making them prone to tipping over in severe weather such as strong winds and heavy rains, or when impacted by external forces. This renders them ineffective in blocking and protecting, posing potential risks to personnel and equipment at the construction site. Second, the installation process is cumbersome. Existing guardrails are difficult and time-consuming to install, as they primarily use bolts and nuts for connection. This makes installation and disassembly labor-intensive, increasing labor costs and slowing down the overall construction progress. Third, they lack flexibility. The protection needs of different construction sites change dynamically, and existing guardrails cannot adjust their height according to terrain differences, which is particularly inconvenient in practical applications. These problems highlight the significant shortcomings in the design and function of current guardrails.

[0004] Therefore, this application provides a protective fence for power construction to overcome the shortcomings of the prior art. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a protective fence for power construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective fence for power construction includes a first protective fence and a second protective fence. The second protective fence has an installation port at its end. A rotating shaft is fixedly connected to the inner wall of the installation port. A connecting plate is rotatably sleeved on the outer wall of the rotating shaft. The connecting plate has a connecting port. The inner wall of the connecting port is rotatably connected to the outer wall of the rotating shaft. The connecting plate is connected to the first protective fence through a snap-fit ​​mechanism. An operating column is rotatably connected to the bottom of the first and second protective fences. The operating column is connected to a lifting sleeve through a lifting mechanism. A fixing mechanism is connected to the bottom of the lifting sleeve.

[0008] As a preferred technical solution, the lifting mechanism includes a sliding plate, the top of which is rotatably connected to the bottom of the operating column, and two symmetrically arranged limiting blocks are fixedly connected to the outer wall of the sliding plate. The inner wall of the lifting sleeve is provided with two limiting grooves that are adapted to the limiting blocks, and the inner wall of the limiting groove is slidably connected to the outer wall of the limiting block.

[0009] As a preferred technical solution, the inner wall of the top of the lifting sleeve is provided with an internal thread, and the outer wall of the bottom of the operating column is provided with an external thread that matches the internal thread. The bottom of the operating column is threadedly connected to the inner wall of the lifting sleeve.

[0010] As a preferred technical solution, the fixing mechanism includes a fixing plate fixedly connected to the bottom of the lifting sleeve, and the fixing plate has fixing holes at four opposite corners, each of which is connected to a pin.

[0011] As a preferred technical solution, the snap-fit ​​mechanism includes storage openings at both ends of the connecting plate, with telescopic rods fixedly connected to the bottom of each of the two storage openings, and rigid heads fixedly connected to the top of each telescopic rod. A telescopic spring is sleeved on the outer wall of the telescopic rod, and the top and bottom of the first guardrail are provided with rotating openings that match the rigid heads.

[0012] As a preferred technical solution, the ends of the two telescopic springs are respectively fixedly connected to the bottom of the receiving opening and the outer wall of the rigid head.

[0013] As a preferred technical solution, the first guardrail is provided with an insertion port at both the end and the bottom, and the two rotating ports are connected to the insertion ports, which are fitted with the connecting plate.

[0014] This utility model has the following advantages compared with the prior art:

It greatly simplifies and optimizes the connection method between the sub-sections of a guardrail, and realizes the rapid installation and disassembly of guardrails. This method saves time and reduces maintenance difficulty, greatly improves work efficiency and reduces labor costs.

[0016] 2. This utility model solves the problem of height flexibility requirements for dynamic terrain adjustment by combining the lifting mechanism and the operating column. The lifting mechanism allows workers to flexibly change the height of each barrier according to specific circumstances to meet the requirements of different geographical features. For example, the height can be adjusted according to the actual situation when working on slopes, uneven or special road sections.

[0017] 3. This utility model greatly simplifies and optimizes the fixing effect of the guardrail through the fixing mechanism, making it less likely to separate and fall apart due to external force.

[0026] 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.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", 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 element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Reference Figure 1-7The protective railing for power construction includes a first protective railing 1 and a second protective railing 2. The second protective railing 2 has an installation port at its end. A rotating shaft 3 is fixedly connected to the inner wall of the installation port. A connecting plate 4 is rotatably sleeved on the outer wall of the rotating shaft 3. The connecting plate 4 has a connecting port 5. The inner wall of the connecting port 5 is rotatably connected to the outer wall of the rotating shaft 3. The connecting plate 4 is connected to the first protective railing 1 through a snap-fit ​​mechanism. This design makes the connection between the two protective railings not only simple and quick but also tight, effectively improving the overall stability and reliability of the entire device. An operating column 14 is rotatably connected to the bottom of the first protective railing 1 and the second protective railing 2. The operating column 14 is connected to a lifting sleeve 11 through a lifting mechanism. A fixing mechanism is connected to the bottom of the lifting sleeve 11.

[0029] The lifting mechanism includes a sliding plate 15, the top of which is rotatably connected to the bottom of the operating column 14, allowing the operating column 14 to move relative to the sliding plate 15 in the vertical direction while maintaining the stability of the connection between the two. Two symmetrically arranged limiting blocks 17 are fixedly connected to the outer wall of the sliding plate 15 to ensure reliable positioning and guiding functions during movement. The inner wall of the lifting sleeve 11 is provided with two limiting grooves 16 that are adapted to the limiting blocks 17. The inner wall of the limiting grooves 16 is slidably connected to the outer wall of the limiting blocks 17. The sliding connection ensures that the entire structure remains stable and reliable during adjustment, avoiding accidental displacement or loosening.

[0030] The inner wall of the top of the lifting sleeve 11 is provided with an internal thread, and the outer wall of the bottom of the operating column 14 is provided with an external thread that matches the internal thread. The bottom of the operating column 14 is threadedly connected to the inner wall of the lifting sleeve 11. The bottom of the operating column 14 and the inner wall of the lifting sleeve 11 form a stable threaded connection, which improves the convenience and stability of the guardrail when used in the power construction environment.

[0031] The fixing mechanism includes a fixing plate 12 fixedly connected to the bottom of the lifting sleeve 11. The fixing plate 12 has fixing ports at four opposite corners. The four fixing ports are evenly distributed and diagonally opposite each other, so that the impact of external force from any direction can be evenly distributed and transmitted to the support base through each pin 13. Each fixing port is connected to a pin 13, and the pin 13 is effectively fixed to the external environment (such as a pre-prepared connection point or support structure on the ground) through these fixing ports.

[0032] The snap-fit ​​mechanism includes storage openings 6 at both ends of the connecting plate 4. A telescopic rod 7 is fixedly connected to the bottom of each of the two storage openings 6. A rigid head 8 is fixedly connected to the top of each telescopic rod 7. A telescopic spring 9 is sleeved on the outer wall of the telescopic rod 7. The top and bottom of the first guardrail 1 are provided with rotating openings 10 that match the rigid head 8. This enables quick assembly and disassembly, improves construction efficiency, and ensures the safety and integrity of the construction site.

[0033] The ends of the two telescopic springs 9 are fixedly connected to the bottom of the storage port 6 and the outer wall of the rigid head 8, respectively, which can ensure that they have a certain rebound and recovery function when subjected to external pressure.

[0034] The first guardrail 1 has an insertion port at both ends and bottom. Two rotating ports 10 are connected to the insertion ports. The insertion ports fit into the connecting plate 4. These structures ensure the flexible use and quick assembly of the guardrail in different situations. The insertion port design of the guardrail can not only fit tightly with the corresponding components, but also allow the rotating components to connect smoothly with it, making the whole system more stable and reliable. This allows the guardrail to be easily adjusted in angle to adapt to the requirements of different construction environments.

[0035] The specific working principle of this utility model is as follows:

[0036] In the initial state, during the installation of the connecting plate 4, the rigid head 8 is first pushed into the rotating opening 10, and the bottom rigid head 8 is pressed down by hand or auxiliary tools to push the connecting plate 4, so that the rigid head 8 enters the rotating opening 10 at the bottom of the first guardrail 1, realizing the snap-fit ​​process. Subsequently, under the force, the telescopic rod 7 can retract or extend, and maintain a certain elasticity under the action of the spring, so that the rigid head 8 is stably in the rotating opening 10. For example, when disassembling, the locking state can be released by simply reversing the operation, restoring the independence of the component for handling and reuse.

[0037] To ensure stable support for the entire guardrail, both the first guardrail 1 and the second guardrail 2 are equipped with rotatable operating columns 14 at their bottom. This design allows workers to make appropriate fine adjustments to the angle of each support point according to the specific conditions on site. When it is necessary to adjust the height of the two guardrail sections, the operating column 14 is driven to move up or down by manipulating the external control system. At the same time, the sliding plate 15 moves vertically along with the operating column 14, while the limiting blocks on both sides of the sliding plate 15 slide along the limiting grooves 16 in the lifting sleeve 11, thereby realizing the height adjustment of the first guardrail 1 and the second guardrail 2. This design not only ensures a smooth and orderly operation process, but also ensures that each component maintains a tight connection and correct positioning, effectively completing the height adjustment task.

[0038] Finally, after the guardrail reaches the required height, a fixing mechanism is installed at the bottom. This component is used to stabilize the overall structure and prevent tilting or collapse under strong winds or other external forces. Through the close cooperation and coordination between the various components, this power construction guardrail not only provides efficient physical isolation and protection, but also has extremely high flexibility and adaptability.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
