Description

Technical Field

[0001] This utility model relates to the field of construction protection technology, and in particular to a detachable guardrail device for onshore wind power foundation pits. Background Technology

[0002] The rapid development and large-scale expansion of wind power construction have led to a surge in demand for temporary protection of foundation pits. In addition, given the special nature of foundation pit protection, there is an urgent need to create a suitable and removable guardrail.

[0003] A search revealed Chinese patent CN221073750U, which discloses a detachable guardrail, including a base with a parallelogram-shaped unfolding guardrail device mounted on the upper part of the base. The parallelogram-shaped unfolding guardrail device includes a base rod and a guardrail rod. This utility model adds a parallelogram-shaped unfolding guardrail device. When unfolding and retracting the parallelogram-shaped unfolding guardrail device, only the fixing pin needs to be pulled out. At this time, the upper end of the diagonal support rod is no longer engaged with the guardrail rod. Personnel can easily manually control the rotation of two or more columns, thereby bringing the guardrail rod closer to the base rod, realizing the quick disassembly and folding of the parallelogram-shaped unfolding guardrail device.

[0004] Based on the above search and existing technology, the following findings were made: The aforementioned patents require manual removal of the fixing steps, resulting in low disassembly and assembly efficiency. Furthermore, in the unfolded state, the hinged nodes are prone to swaying under wind loads, exhibiting insufficient resistance to lateral forces. Transportation costs are high, and the space utilization rate is reduced when irregularly shaped buckles are mixed with rods. In addition, buckles are easily lost during transportation, thus presenting certain limitations. Utility Model Content

[0005] To address the aforementioned technical issues, this utility model proposes a detachable guardrail device for onshore wind power pits, achieving gravity self-locking connection and replacing the traditional bolt and clip structure.

[0006] The technical solution to achieve the purpose of this utility model is: a detachable guardrail device for onshore wind power pits, including a pair of lower main uprights and a pair of upper main uprights, as well as horizontal bars and connecting components. The horizontal bars are respectively installed between a pair of lower main uprights and a pair of upper main uprights; The connecting assembly includes sleeves that are fixedly installed on both sides of the lower main upright and the upper main upright.

[0007] Preferably, a first hinge seat is fixedly installed at one end of the lower main upright, and a second hinge seat is fixedly installed at one end of the upper main upright, with the first hinge seat and the second hinge seat connected by a cylindrical pin.

[0008] Preferably, insertion tubes are fixedly installed on both sides of the horizontal bar, and the insertion tubes are inserted into the inside of the sleeve. Reflective strips are fixedly installed on one side of both the lower main upright and the upper main upright.

[0009] Compared with existing technologies, the significant advantages of this invention are: Firstly, this utility model offers a significant leap in efficiency, shortening the installation time for a single set of guardrails; and through vibration testing, the connection points show zero loosening, improving resistance to lateral forces; additionally, the reflective strips automatically emit light at night, enhancing visibility.

[0010] Secondly, this utility model eliminates buckles, saving procurement costs; adopts a hinged structure, reducing transportation volume; extends component lifespan; improves construction friendliness; reduces overall weight; and makes it easier to handle.

[0011] This invention solves the problems of existing patents requiring manual removal of the fixing steps, resulting in low disassembly and assembly efficiency, and the fact that the hinged nodes are prone to swaying under wind loads when unfolded, leading to insufficient resistance to lateral forces; high transportation costs; reduced space utilization when irregularly shaped buckles are mixed with rods; and the buckles being easily lost during transportation.

[0014] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 are within the protection scope of the present invention.

[0015] This utility model provides an improved detachable guardrail device for onshore wind power foundation pits. The technical solution of this utility model is as follows: Example

[0016] like Figures 1-2 As shown, a detachable guardrail device for onshore wind power pits includes a pair of lower main uprights 1 and a pair of upper main uprights 101. The uprights and horizontal bars 2 are made of aluminum alloy, which is lightweight, has improved corrosion resistance, and extends service life. It also includes the horizontal bars 2 and connecting components. The horizontal bars 2 are respectively installed between a pair of lower main uprights 1 and a pair of upper main uprights 101, and the risk of vibration loosening is eliminated through a structural self-locking mechanism; The connecting assembly includes sleeves 3 that are fixedly installed on both sides of the lower main upright 1 and the upper main upright 101. The sleeves 3 are integrally formed with the uprights to eliminate welding deviations. Example

[0017] Based on the detachable guardrail device for onshore wind power foundation pits provided in the first embodiment of this application, the second embodiment of this application proposes another detachable guardrail device for onshore wind power foundation pits. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0018] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 3-4 As shown, a first hinge seat 4 is fixedly installed at one end of the lower main upright 1, and a second hinge seat 5 is fixedly installed at one end of the upper main upright 101. The first hinge seat 4 and the second hinge seat 5 are connected by a cylindrical pin. The upright adopts a hinge structure, which can be folded during transportation to improve space utilization.

[0020] Furthermore, insertion pipes are fixedly installed on both sides of the horizontal pole 2, and the insertion pipes are inserted into the inside of the sleeve 3. Reflective strips 6 are fixedly installed on one side of both the lower main pole 1 and the upper main pole 101, and photovoltaic energy storage fluorescent film is pasted on the surface, which automatically emits light at night and improves visibility.

[0021] The specific working method is as follows: First, drill holes according to the design spacing to insert the upright units. Then, symmetrically weld four sleeves 3 of the same specification on both sides of the main pole to form a double-layer protective reference surface. Insert the horizontal pole 2 unit into the sleeve 3 vertically and allow it to fall freely to complete gravity self-locking. This achieves neat bundling of pure pole components, improves the utilization rate of transportation space, and both the upright and horizontal poles 2 are made of aluminum alloy. The aluminum alloy surface needs to be anodized to prevent wind and sand abrasion. Then, check the flatness of the horizontal pole 2 with a level. Finally, install reflective strips 6 on both the upright and horizontal poles 2.

[0022] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
