Description

Technical Field

[0001] This utility model belongs to the field of coal gangue base construction, specifically relating to a geotextile spreading device for coal gangue base construction. Background Technology

[0002] Laying geotextile is an important step in the construction of coal gangue base courses. As a material with functions such as filtration, isolation, drainage, and reinforcement, geotextile plays a key role in the construction of coal gangue base courses.

[0003] Traditional geotextile paving methods mostly rely on manual labor or simple machinery. On the one hand, manual paving is inefficient and labor-intensive; on the other hand, some simple paving machines have fixed structures, making it difficult to flexibly adjust according to the width of the coal gangue base layer and thus unsuitable for geotextiles of different widths.

[0004] Therefore, we propose a geotextile spreading device for coal gangue base construction to solve the above problems. Utility Model Content

[0005] In view of the problems that traditional geotextile paving methods mostly rely on manual or simple mechanical operations, manual paving is inefficient and labor-intensive; and some simple paving machines have fixed structures, making it difficult to flexibly adjust according to the width of the coal gangue base layer and thus unable to accommodate geotextiles of different widths, this utility model provides a geotextile paving device for coal gangue base layer construction.

[0006] The solution adopted by this utility model to solve its technical problem is: a geotextile spreading device for coal gangue base construction, including an outer arm, a guide rod, a guide plate and two symmetrically arranged channel steels, and two connecting ear plates for connecting with the excavator bucket arm are welded and fixed to the top of the outer arm;

[0007] The outer arm has extension arms at both ends, which can slide along the inner cavity of the outer arm and are connected to the outer arm by a positioning component.

[0008] The channel steel is welded and fixed to one end of the extension arm away from the outer arm, and two support wheels for supporting the geotextile shaft are fixedly installed inside the channel steel;

[0009] A V-shaped arm is welded and fixed to the bottom of the channel steel. A through hole is opened at the bend of the V-shaped arm, and a sliding groove is opened at its lower end. The two ends of the guide rod pass through the through holes on both sides respectively.

[0010] The guide plate is set in two grooves and can slide along the grooves.

[0011] Preferably, the outer arm has a threaded hole at each end, and the extension arm has multiple positioning holes at the end near the outer arm.

[0012] Preferably, the positioning element is a positioning bolt, with the inner end of the positioning bolt passing through a threaded hole and inserted into the corresponding positioning hole.

[0013] Preferably, the guide rod has multiple threaded grooves at both ends, and the two V-arms have stop bolts on their opposite sides, with the stop bolts threadedly connected to the corresponding threaded grooves.

[0014] Preferably, the guide plate has multiple reserved holes at both ends, and the lower end of the V-shaped arm has a threaded hole II. A fixing bolt is internally threaded into the threaded hole II, and the inner end of the fixing bolt is inserted into the corresponding reserved hole.

[0015] Preferably, it also includes a lower pressure roller and a threaded rod. The lower pressure roller is positioned above the material shaft, the upper end of the threaded rod is connected to the lower pressure roller, and its lower end passes through an installation hole opened at the bottom of the channel steel and is threaded with a nut.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model allows the extension arm to slide along the inner cavity of the outer arm, and the spacing between the two channel steels can be flexibly adjusted by the cooperation of the positioning bolts and different positioning holes, so as to facilitate the installation of geotextiles of different widths and adapt to the construction of coal gangue base courses of different widths. Furthermore, the guide rod can slide in the through hole and the guide plate can slide in the chute, which can adapt to the position adjustment of the two V-shaped arms and meet the paving requirements of geotextiles under different working conditions.

[0018] 2. This utility model uses two support wheels to support the material shaft of the geotextile, reducing the resistance and friction of the geotextile during the paving process, so that the geotextile can be spread out smoothly and stably.

[0019] 3. This utility model, through the design of guide rods and guide plates, can effectively guide and position geotextiles, thereby improving the flatness and quality of geotextile paving.

[0020] 4. This utility model connects to the excavator boom via a connecting ear plate, and uses the excavator's power to spread the geotextile. Compared with traditional manual spreading, this significantly reduces labor intensity, greatly improves construction efficiency, and reduces labor costs and construction time.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figure 1-2 This utility model provides a technical solution for a geotextile spreading device for coal gangue base construction:

[0026] Example 1:

[0027] according to Figure 1 As shown, it includes an outer arm 1, a guide rod 71, a guide plate 91, and two symmetrically arranged channel steels 62. The top of the outer arm 1 is welded and fixed with two connecting ear plates 2 for connecting with the excavator's stick. By connecting with the excavator's stick through the connecting ear plates 2, the geotextile is laid with the help of the excavator's power. Compared with traditional manual laying, it greatly reduces labor intensity, significantly improves construction efficiency, and reduces labor costs and construction time.

[0028] The outer arm 1 has threaded holes at both ends and extension arms 3 at both ends. The extension arms 3 can slide along the inner cavity of the outer arm 1. The length of the extension arms 3 extending out of the outer arm 1 can be controlled according to the width of the geotextile to be laid. The end of the extension arm 3 near the outer arm 1 has multiple positioning holes 31. It is connected to the outer arm 1 by positioning components, namely positioning bolts 4. The inner end of the positioning bolts 4 passes through the threaded holes and is inserted into the corresponding positioning holes 31 to fix the position of the extension arms 3.

[0029] The channel steel 62 is welded and fixed to one end of the extension arm 3 away from the outer sleeve arm 1. Two support wheels 61 for supporting the geotextile material shaft 10 are fixedly installed inside the channel steel 62. The two support wheels 61 support the geotextile material shaft 10, reducing the resistance and friction of the geotextile during the paving process, so that the geotextile can be spread out smoothly and stably.

[0030] A V-shaped arm 8 is welded and fixed to the bottom of the channel steel 62. A diagonal brace 5 is welded and fixed between the channel steel 62 and the V-shaped arm 8. A through hole is opened at the bend of the V-shaped arm 8, and a sliding groove is opened at its lower end.

[0031] The two ends of the guide rod 71 are respectively through the through holes on both sides. Multiple threaded grooves 72 are opened at both ends of the guide rod 71. Stop bolts 73 are respectively provided on the opposite sides of the two V-shaped arms 8. The stop bolts 73 are threadedly connected to the corresponding threaded grooves 72. Under the limiting action of the two stop bolts 73, the guide rod 71 will not slide back and forth.

[0032] The guide plate 91 is set in two chutes and can slide along the chutes. Through the design of the guide rod 71 and the guide plate 91, the geotextile can be effectively guided and positioned, improving the flatness and quality of the geotextile paving. Multiple reserved holes 92 are opened at both ends of the guide plate 91. The lower end of the V-shaped arm 8 is opened with a threaded hole II. The threaded hole II is internally threaded with a fixing bolt 93. The inner end of the fixing bolt 93 is inserted into the corresponding reserved hole 92 to fix the position of the guide plate 91.

[0033] In practical use, the geotextile spreading device for coal gangue base construction of this utility model first connects the two connecting ear plates 2 to the excavator stick to ensure a firm and reliable connection. The power of the excavator provides support for the subsequent geotextile spreading. Then, the extension arm 3 is pushed to move. The length of the extension arm 3 extending out of the outer arm 1 is controlled according to the determined spreading width.

[0034] After adjusting the positions of the two extension arms 3, the inner end of the positioning bolt 4 is inserted through the threaded hole and into the corresponding positioning hole 31 to fix the position of the extension arm 3. One end of the guide rod 71 is then passed through the two through holes one by one. Then, the two stop bolts 73 are threaded to the corresponding threaded grooves 72 at both ends of the guide rod 71. The guide rod 71 is prevented from sliding back and forth by the limiting effect of the two stop bolts 73, thus maintaining its stability. After that, the guide plate 91 is slid into the two grooves and the position of the guide plate 91 is fixed by the fixing bolts 93.

[0035] Place the geotextile shaft 10 on the front and rear sets of support wheels 61, and then pass one end of the geotextile around the guide rod 71 and guide plate 91 in sequence. Finally, operate the excavator to spread the geotextile.

[0036] Example 2:

[0037] Based on Example 1, such as Figure 2 As shown, it also includes a lower pressure roller 64 and a threaded rod 63. The lower pressure roller 64 is located above the material shaft 10. The upper end of the threaded rod 63 is connected to the lower pressure roller 64, and its lower end passes through the mounting hole opened at the bottom of the channel steel 62 and is threaded with a nut 65, so that the lower pressure roller 64 is in continuous contact with the material shaft 10, preventing the material shaft 10 from detaching from the two support rollers 61.
