Description

Technical Field

[0001] This utility model relates to the field of construction fence technology, specifically to a hydraulic protection railing that is easy to install. Background Technology

[0002] During water conservancy construction, the construction period is usually long and the surrounding environment of the construction site is complex, with many potential safety hazards, such as excavation areas, temporary structures, and the operating range of machinery and equipment. In order to ensure the safety of passing construction vehicles and personnel and prevent dangerous accidents, it is necessary to set up warning fences around the construction site to clearly define the scope of the construction site.

[0003] Traditional warning and protective fences for water conservancy projects have certain limitations, and are insufficient in terms of flexibility and convenience. Some fences are large in size, occupying a lot of space during transportation and storage, increasing transportation costs and storage difficulties. Even if some fences can be disassembled, they are mostly fixed with bolts. On the one hand, bolts are prone to rust and loosening. On the other hand, the bolts need to be tightened during the installation of the protective fence, and tools are needed to tighten them again at the end. When the construction site needs to be adjusted at any time according to the progress of the project, these fences are difficult to adapt to the changes in site quickly and flexibly, and cannot meet the needs of dynamic construction of water conservancy projects. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a hydraulic protection railing that is easy to install and can effectively solve the problems of the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a hydraulic protection railing that is easy to install, including a first railing body and a second railing body that are horizontally connected and distributed. The right end of the first railing body is provided with a plug groove, and the left end of the second railing body is provided with a sliding plate corresponding to the position of the plug groove. The lower end of the sliding plate is provided with a limit groove, and the first railing body is provided with a limit component that cooperates with the limit groove.

[0007] The limiting component includes a sliding groove on the first fence body that communicates with the insertion slot. The sliding groove is slidably connected to a limiting block. Multiple limiting springs are fixedly connected between the limiting block and the sliding groove. Two sliding rods are fixedly connected to the lower end of the limiting block. The lower ends of the two sliding rods are jointly fixedly connected to a connecting rod.

[0008] According to the above-mentioned easy-to-install water conservancy protective railing, a sliding cavity is provided at the left end of the second fence body, the sliding plate is slidably connected to the sliding cavity, and a threaded hole communicating with the lower side of the sliding cavity is provided in the second fence body, and a bolt is threaded into the threaded hole.

[0009] According to the above-mentioned easy-to-install hydraulic guardrail, the length of the sliding cavity is greater than the length of the sliding plate, and the shape of the sliding plate is adapted to the shape of the insertion groove.

[0010] According to the aforementioned water conservancy protective railing that is easy to install, the limiting block has a beveled edge at one end near the sliding plate.

[0011] According to the aforementioned easy-to-install hydraulic protection railing, multiple limit springs are respectively set on the outside of the sliding rod.

[0012] According to the aforementioned easy-to-install hydraulic protection railing, both the first and second railing bodies are provided with multiple through holes.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] This utility model adopts a "plug-in + spring limiting" structure, which eliminates the need for tools such as screwdrivers. Simply insert the sliding plate and it will automatically lock through the limiting block and the limiting spring. This improves the fixing efficiency by more than 80% compared to traditional bolts and solves the problem of tedious operation that requires multiple tightening of bolts.

[0015] This invention allows the fence body to be folded into a compact structure through the cooperation of the sliding plate and the sliding cavity. The volume is reduced after folding, and it can be stacked for storage during transportation, which significantly reduces the space occupied by transport vehicles and the cost of warehouse storage.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: Refer to Figures 1 to 4 The easy-to-install water conservancy protective railing includes a first fence body 1 and a second fence body 2 that are horizontally connected. The fence body is made of hot-dip galvanized steel pipe and the surface is sprayed with outdoor special anti-corrosion paint. It has strong resistance to salt spray corrosion and is suitable for the complex environment of humid and high salt spray in water conservancy projects. Its service life is 2-3 times longer than that of traditional fences.

[0025] Both the first fence body 1 and the second fence body 2 have multiple through holes 13. The through holes 13 are used to reduce wind resistance, which can effectively reduce wind resistance by more than 30%, improve the stability of the fence in strong wind environments, and reduce the overall weight by about 15%, making it easier to transport.

[0026] The right end of the first fence body 1 is provided with a plug-in groove 3, and the left end of the second fence body 2 is provided with a sliding plate 10 corresponding to the position of the plug-in groove 3. The lower end of the sliding plate 10 is provided with a limiting groove 11. The first fence body 1 is provided with a limiting component that cooperates with the limiting groove 11. Specifically, the limiting component includes a sliding groove 4 on the first fence body 1 that communicates with the plug-in groove 3. The sliding groove 4 is slidably connected to a limiting block 5. The end of the limiting block 5 near the sliding plate 10 is provided with a beveled edge, which makes it easy for the limiting block 5 to automatically move when the sliding plate 10 is inserted.

[0027] The left end of the second fence body 2 is provided with a sliding cavity 9. The sliding plate 10 is slidably connected to the sliding cavity 9. The length of the sliding cavity 9 is greater than the length of the sliding plate 10, and the shape of the sliding plate 10 is adapted to the shape of the insertion slot 3, so that the sliding plate 10 can be completely put into the sliding cavity 9, ensuring that the sliding plate 10 can be completely put into the cavity. After folding, the overall length is reduced, the space occupied is reduced, and transportation is convenient.

[0028] The second fence body 2 has a threaded hole that communicates with the lower side of the sliding cavity 9. A bolt 12 is threaded into the threaded hole to fix the sliding plate 10 in the sliding cavity 9. The bolt 12 is made of stainless steel. After tightening, the sliding plate 10 can be fixed in the sliding cavity 9 to prevent shaking during transportation.

[0029] Multiple limiting springs 6 are fixedly connected between the limiting block 5 and the sliding groove 4. Two sliding rods 7 are fixedly connected to the lower end of the limiting block 5. The multiple limiting springs 6 are all arranged on the outside of the sliding rods 7 in a corresponding manner to avoid the problem of elastic deformation of multiple limiting springs 6 and increase the service life of the limiting springs 6.

[0030] The lower ends of the two sliding rods 7 are fixedly connected to a connecting rod 8. Pulling the connecting rod 8 downwards can cause the two sliding rods 7 to slide downwards, causing the limiting block 5 to disengage from the limiting groove 11.

[0031] The working principle of this utility model is as follows:

[0032] During installation, pull the sliding plate 10 of the second fence body 2 out of the sliding cavity 9 (unlocking bolt 12), align it with the insertion slot 3 of the first fence body 1 and push it horizontally. When the sliding plate 10 is inserted, the front end of its lower limit groove 11 contacts the beveled edge of the limit block 5, pushing the limit block 5 to overcome the resistance of the limit spring 6 and slide into the sliding groove 4. When the limit groove 11 is fully inserted into the insertion slot 3, the limit block 5 corresponds to the position of the limit groove 11, the limit spring 6 resets, and drives the limit block 5 to be locked into the limit groove 11, completing the mechanical locking.

[0033] During disassembly, pull down the connecting rod 8, and the sliding rod 7 will move the limiting block 5 down, causing it to disengage from the limiting groove 11, thus detaching the two fence bodies.

[0034] When folding and storing, push the sliding plate 10 completely into the sliding cavity 9 and tighten the bolt 12 to fix it. At this time, the fence body is in a compact state and can be neatly stacked or packed into a transport box for convenient transportation and storage.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
