DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present system will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment:

[0020] As Figure 1 shown, the present utility model provides a fixing device for the discharge end of an underground filling pipeline

[0021] It includes a first semi-circular steel pipe 1, a second semi-circular steel pipe 2, a lower shaping steel plate 3, and an upper shaping steel plate 4. One side of the first semi-circular steel pipe 1 is hinged to one side of the second semi-circular steel pipe 2. A locking device is arranged between the other side of the first semi-circular steel pipe 1 and the other side of the second semi-circular steel pipe 2. The lower shaping steel plate 3 is arranged at the lower end of the first semi-circular steel pipe 1, and the upper shaping steel plate 4 is arranged at the upper end of the second semi-circular steel pipe 2. A first telescopic rod hinge point 5 is arranged on the lower shaping steel plate 3. The first telescopic rod is hinged to the lower shaping steel plate 3 through the first telescopic rod hinge point 5. The first telescopic rod is used to support both sides of the filling roadway. A second telescopic rod hinge point 6 is arranged on the upper shaping steel plate 4. The second telescopic rod is hinged to the upper shaping steel plate 4 through the second telescopic rod hinge point 6. The second telescopic rod is used to support the top of the filling roadway.

[0022] It should be noted that in the fixing device at the discharge end of the underground filling pipeline, the hinged manner between the first telescopic rod and the first telescopic rod hinge point 5 is realized through a hinge. This hinged design allows the first telescopic rod to make an angular adjustment within a certain range relative to the lower shaping steel plate 3 to adapt to different roadway conditions and support requirements.

[0023] Specifically, the first telescopic rod hinge point 5 is a structure pre-designed on the lower shaping steel plate 3. This structure includes one or more holes or grooves for installing the hinge. One end of the first telescopic rod is equipped with hinge components matching these holes or grooves. During installation, the hinge components are inserted into the holes or grooves and fixed by fasteners such as bolts and nuts, thus completing the hinge between the first telescopic rod and the lower shaping steel plate 3.

[0024] The second telescopic rod hinge point 6 is a specific area pre-designed on the upper shaping steel plate 4. This area contains holes, grooves or fixing devices for installing the hinge. One end of the second telescopic rod is equipped with hinge components matching the hinge point. The hinge components are inserted into the holes or grooves on the upper shaping steel plate 4 and firmly fixed by fasteners such as bolts, nuts and pins. After completion of the hinge, the second telescopic rod will be able to make an angular adjustment within a certain range around the hinge point to adapt to the shape and changes of the top of the filling roadway.

[0025] By combining the length adjustment and angular adjustment functions of the second telescopic rod, it can be ensured that the second telescopic rod effectively supports the top of the filling roadway, thereby enhancing the stability and safety of the entire fixing device.

[0026] The first telescopic rod is hinged to both sides of the lower shaping steel plate 3, mainly playing a supporting role, stably fixing the discharging end of the filling pipeline on both sides of the filling roadway. Through telescopic adjustment, it can adapt to roadways of different widths and shapes, ensuring the stability of the pipeline discharging end. The design of the first telescopic rod allows the length to be adjusted according to the actual roadway conditions, which improves the adaptability and flexibility of the device. Whether it is a narrow or wide roadway, the best supporting effect can be achieved by adjusting the length of the telescopic rod.

[0027] During the filling operation, the discharging end of the pipeline will be subjected to the pressure and impact force from the filling material. As part of the supporting structure, the first telescopic rod can effectively share these loads and protect the pipeline and fixing device from damage.

[0028] The second telescopic rod is hinged to the upper end of the upper shaping steel plate 4, mainly supporting the top of the filling roadway. This design ensures the stability of the pipeline discharging end in the vertical direction, preventing shaking or deviation caused by the filling operation. Similar to the first telescopic rod, the second telescopic rod also has a length adjustment function, which allows for flexible adjustment according to the height of the roadway top, ensuring the supporting effect while also improving the applicability of the device under different roadway conditions.

[0029] The second telescopic rod cooperates with the first telescopic rod to jointly form a stable supporting system. This system can not only effectively fix the discharging end of the pipeline but also provide the necessary stability guarantee during the filling operation to ensure the smooth progress of the operation.

[0030] The lower shaping steel plate 3 is arranged in several groups, and the several groups of the lower shaping steel plate 3 are evenly spaced;

[0031] The upper shaping steel plate 4 is arranged in several groups, and the several groups of the upper shaping steel plate 4 are evenly spaced.

[0032] A plurality of mounting holes are provided on both the lower shaping steel plate 3 and the upper shaping steel plate 4 for fixing the first semi-circular steel pipe 1 and the second semi-circular steel pipe 2 to the lower shaping steel plate 3 and the upper shaping steel plate 4 respectively through bolts.

[0033] The locking device includes a locking tongue and a locking buckle. The locking tongue is arranged on the other side of the first semi-circular steel pipe 1, and the locking buckle is arranged on the other side of the second semi-circular steel pipe 2. The locking tongue and the locking buckle cooperate to achieve the locking function to prevent the first semi-circular steel pipe 1 and the second semi-circular steel pipe 2 from accidentally opening at the hinge.

[0034] The locking device is arranged in several groups, and the several groups of the locking device are evenly spaced.

[0035] This application realizes the stable fixation of the discharge end of the underground filling pipeline through an adjustable support structure. Specifically, the articulated design of the semi-circular steel pipe, the safety locking of the locking device, and the support adjustment function of the telescopic rod together constitute a fixing device with strong adaptability and good stability.

[0036] The first semi-circular steel pipe 1 and the second semi-circular steel pipe 2, as the main structures of the fixing device, achieve the opening and closing function through the articulated setting on one side, which is convenient for installation and disassembly; on the other side, they are fixed by the locking device to ensure that the discharge end of the pipeline is tightly wrapped.

[0037] Locking device: Installed on the unarticulated side of the two semi-circular steel pipes, used to firmly lock the two to prevent loosening or falling off during the filling operation.

[0038] The lower shaped steel plate 3 and the upper shaped steel plate 4 are respectively arranged at the upper and lower ends of the semi-circular steel pipe, serving as the support basis for the telescopic rod to ensure that the telescopic rod can stably support the two sides and the top of the roadway.

[0039] The first telescopic rod and the second telescopic rod are connected to the shaped steel plate through the hinge point, with the length adjustment function, and can be flexibly adjusted according to the size and shape of the roadway to achieve stable support.

[0040] During the use of this application, the following working steps are included
