Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically a safety protection device for pipeline construction in narrow trenches. Background Technology

[0002] Narrow trenches used for burying pipelines are generally excavated in non-motorized vehicle lanes and include: vertical trenches and trenches with sloping surfaces. Generally, the minimum width of a narrow trench for burying a 600mm diameter pipeline is only 1.45m, that is: a narrow trench with a width of only 1.45m can be excavated.

[0003] In pipeline trench construction, due to the limitations of the construction environment and space, some municipal pipeline trenches cannot be excavated with slopes, and excavation is mostly done vertically. Especially in confined spaces and narrow trenches, construction workers face many safety risks, such as trench collapse and falling objects. If protection is not in place, it can easily cause casualties. Therefore, developing a reliable safety protection device for pipeline construction in confined spaces and narrow trenches is of great practical significance. The developed safety protection device can provide effective safety protection for personnel performing tasks such as elevation measurement, trench bottom cleaning and leveling, and pipe section installation in the trench after excavation, reducing the probability of accidents and protecting the lives of construction workers.

[0025] 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.

[0026] Example 1, please refer to Figures 1-7 This utility model provides a technical solution: a safety protection device for pipeline construction in narrow trenches, including a first protective plate 1 and a second protective plate 2. Extension plates 3 are slidably arranged on both the first protective plate 1 and the second protective plate 2. The two sets of extension plates 3 are fixedly connected to the first protective plate 1 and the second protective plate 2 respectively by fastening bolts 4. A first adjusting support rod 5 is arranged between the first protective plate 1 and the second protective plate 2, and a second adjusting support rod 6 is arranged between the two sets of extension plates 3. The first adjusting support rod 5 and the second adjusting support rod 6 adjust the distance between the first protective plate 1 and the second protective plate 2 by telescopic movement.

[0027] The first adjusting support rod 5 includes two sets of positioning seats 501 fixed on the surfaces of the first protective plate 1 and the second protective plate 2. The first support rod 502 and the second support rod 503 are respectively hinged to the two sets of positioning seats 501. The end of the second support rod 503 is slidably inserted into the interior of the first support rod 502. The first support rod 502 and the second support rod 503 are each provided with several sets of positioning holes 504, and the first support rod 502 and the second support rod 503 are fixedly connected by a tightening screw 505.

[0028] The second adjusting support rod 6 has the same structure as the first adjusting support rod 5.

[0029] In this technical solution, the first protective plate 1 and the second protective plate 2 are provided with cavities 16 for the extension plate 3 to slide. The extension plate 3 is provided with several sets of threaded holes 17 for the fastening bolts 4 to be screwed into. By screwing the fastening bolts 4 out of one set of threaded holes 17, the extension plate 3 can slide relative to the first protective plate 1 and the second protective plate 2, thereby adjusting the exposed length of the extension plate 3. Then, the fastening bolts 4 are screwed into another set of threaded holes 17 to complete the re-fixing of the extension plate 3. By adjusting the exposed length of the extension plate 3, it can adapt to trenches of different depths.

[0030] In this technical solution, by setting the first adjusting support rod 5 and the second adjusting support rod 6, and by sliding the second support rod 503 relative to the first support rod 502, the overall length of the first adjusting support rod 5 and the second adjusting support rod 6 can be adjusted. Then, by tightening the bolt into the positioning hole 504, the relative position of the first support rod 502 and the second support rod 503 is fixed, thereby changing the distance between the first protective plate 1 and the second protective plate 2, so as to facilitate the construction needs of trenches of different widths.

[0031] In Example 2, when working inside a trench, personnel need to stand between the first protective plate 1 and the second protective plate 2. In deeper trenches, there is a risk of collapse. When personnel are positioned between the first and second protective plates, it is difficult for them to avoid the collapse, potentially causing soil to fall on them and injure them. To address this issue, improvements are made based on Example 1. Please refer to [link / reference]. Figures 1-7 The inner surfaces of the first protective plate 1 and the second protective plate 2 are both provided with storage grooves 7. A rotating rod 8 is fixed inside the storage groove 7. A flap 9 is rotatably arranged on the circumference of the rotating rod 8. The flap 9 rotates out from inside the storage groove 7 by rotating around the rotating rod 8.

[0032] The inner surfaces of the first protective plate 1 and the second protective plate 2 are both provided with sliding grooves 10. A protruding plate 11 is elastically provided in the sliding groove 10. A limiting rod 12 is fixed on the surface of the protruding plate 11. A slot 13 for the limiting rod 12 to be inserted is provided on the surface of the flip plate 9.

[0033] In this technical solution, when the first protective plate 1 and the second protective plate 2 are placed inside the trench, personnel should, before construction, such as... Figure 5 As shown, a spring 18 is fixed between the slot 13 and the protrusion 11. By pulling the protrusion 11 to the right, the protrusion 11 compresses the spring 18, causing the spring 18 to store force for the subsequent reset of the protrusion 11. Then, the protrusion 11 drives the limiting rod 12 to move to the right, moving the end of the limiting rod 12 out of the slot 13, releasing the restriction on the flip plate 9, allowing the flip plate 9 to rotate and rotate out of the storage slot 7. Finally, the two flip plates 9 form a shape as shown in the image. Figure 7 The state creates a safe zone under the flap 9, allowing personnel to take shelter under the flap 9 in the event of a collapse, thereby increasing their safety. In addition, the flap 9 allows subsequent personnel to climb out of the trench.

[0034] Example 3 is an improvement on Example 2. Please refer to [link / reference]. Figures 1-7 Both ends of the extension plate 3 are fixed with lifting rings 14;

[0035] Several sets of pulleys 15 are fixed to the bottom of both the first protective plate 1 and the second protective plate 2.

[0036] In this technical solution, the lifting ring 14 facilitates the movement of the first protective plate 1 and the second protective plate 2 into the trench by hoisting, thereby increasing safety; the several sets of pulleys 15 facilitate the movement of the first protective plate 1 and the second protective plate 2 inside the trench, saving time and effort.

[0037] 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.
