Description

Iron ore goaf filling device Technical Field

[0001] This utility model belongs to the field of iron ore mining technology, specifically relating to an iron ore goaf filling device. Background Technology

[0002] During the iron ore mining process, goaf areas will exist in the tunnels. These goaf areas need to be backfilled in a timely manner before they can be used by workers.

[0003] A filling device for an iron ore goaf, disclosed in CN222208004U, includes several steel pipes, adjacent steel pipes being detachably and fixedly connected; a support plate, detachably and fixedly connected to the top of the uppermost steel pipe; a first support mesh, fixedly connected to the inner wall of the U-shaped groove of the support plate; two rotating plates, respectively rotatably connected to both ends of the support plate; two second support meshes, respectively fixedly connected to the two rotating plates; positioning grooves are provided on the side wall of the goaf corresponding to the positions of the rotating plates, and the end of the rotating plate away from the support plate rotates into the positioning groove; several telescopic rods are rotatably mounted on the outer side wall of the several steel pipes; several connecting plates are rotatably mounted on the ends of the telescopic rods away from the steel pipes, and the connecting plates are fixedly connected to the inner side wall of the goaf; this utility model has the advantages of being easy to use, not protruding from the bottom of the roadway, easy to disassemble, install and transport, and reusable.

[0004] However, when the device provided by the above patent is used, the steel pipe and the base plate are fixed by bolts, which makes it impossible to adjust the angle between the two. This means that the contact surface of the base plate must be flat during installation to ensure that the backfilling device is installed vertically. Consequently, if the terrain is uneven, the contact surface of the base plate needs to be leveled. At the same time, the steel pipe and the base, as well as the support plate and the steel pipe, are all rigidly connected, making them susceptible to displacement due to material impact during filling.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this utility model is to provide a filling device for iron ore goaf, which can solve the problems of inconvenient installation of filling devices in uneven terrain and the inability of filling devices to effectively buffer the impact of materials.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] Iron ore goaf filling device, including:

[0009] The main structure includes multiple extension rods to allow for length adjustment based on pit depth during filling. A top rod is detachably mounted on each extension rod, serving as a support for the upper end of the filling device. The extension rods and top rods together form the main support for the backfilling device. A second sleeve is fixedly connected to the top of each extension rod, and the bottom of the top rod is installed within the second sleeve, facilitating installation between extension rods and between the extension rod and the top rod. A base plate is mounted on the bottom of each extension rod, contacting the bottom surface of the backfill pit and providing bottom support for the backfilling device. A rotating seat is mounted on the base plate, and a first sleeve is mounted on the rotating seat, allowing the first sleeve to rotate. The lower end of the extension rod is installed inside the first sleeve, allowing it to be fixed in place. Rotation of the first sleeve allows the extension rod to rotate after installation, enabling position adjustment when the base plate is installed in an uneven pit. This ensures the extension rod remains vertical, facilitating the installation of the filling device. Furthermore, the rotation of the extension rod eliminates the need to level the ground in contact with the base plate during installation, further simplifying the backfilling device installation. Buffer pads are installed on the inner walls of both the first and second sleeves. These buffer pads cushion the impact of materials on the extension rod and top rod installed within the first and second sleeves, preventing displacement of the backfilling device due to material impact.

[0010] The auxiliary mechanism includes a first support rod, which is detachably mounted on a top rod. Second support rods are hinged to both sides of the first support rod. Fixed rods are hinged to the left and right side walls of the extension rod and the top rod, and telescopic rods are installed within the fixed rods. The first and second support rods combine to form a planar support, providing shielding and protection for the pit surface, ensuring safe passage for workers.

[0011] In one or more embodiments of this utility model, the outer wall of the extension rod placed inside the first sleeve and the outer wall of the top rod placed inside the second sleeve both abut against the inner wall of the corresponding buffer pad, so that the buffer pad can effectively buffer the impact force received by the extension rod and the top rod, thereby achieving buffering when the backfilling device is impacted by materials. A first fixing screw is installed through the extension rod and the first sleeve, as well as through the top rod and the second sleeve, in a left-right through-type manner.

[0012] In one or more embodiments of this utility model, a locking nut is installed on the threaded end of the first fixing screw, and the locking nut is a double nut combination. The first fixing screw and the locking nut ensure stable installation of the extension rod, top rod, and bottom plate, thereby ensuring the stability of the backfilling device structure. Furthermore, the use of double nuts effectively prevents the locking nut from loosening when the backfilling device is impacted by materials, ensuring the stability of the connection structure.

[0013] In one or more embodiments of this utility model, the buffer pad is made of rubber material with excellent impact resistance and weather resistance, which makes the buffer pad have excellent cushioning performance and a long service life.

[0014] In one or more embodiments of this utility model, the rotating seat includes a pair of mounting plates, which are fixedly connected to the base plate.

[0015] In one or more embodiments of this utility model, the first sleeve is rotatably connected between a pair of mounting plates, and pivots are fixedly connected to the outer sides of both the front and rear side walls of the first sleeve. Through the cooperation of the rotating seat formed by the pair of mounting plates and the pivots, the first sleeve is structurally stable while rotating on the base plate.

[0016] In one or more embodiments of this utility model, the pivot is rotatably connected to the mounting plate in a through manner, and a buffer ring is installed between the mounting plate and the pivot. By setting the buffer ring, when the material impacts the backfilling device, the first sleeve transmits the impact force to the mounting plate through the pivot, and the impact force can be buffered by the buffer ring, thereby further buffering the impact force received by the backfilling device.

[0017] In one or more embodiments of this utility model, a top plate is fixedly connected to the top of the top rod, and a plurality of limiting protrusions are fixedly connected to the bottom of the bottom plate. The limiting protrusions allow the bottom plate to be installed in the pit, and prevent the second fixing screw from moving laterally when it is installed in the pit.

[0018] In one or more embodiments of this utility model, the first support rod is mounted on the top plate, and a plurality of second fixing screws are installed between the top plate and the first support rod.

[0019] In one or more embodiments of this utility model, mounting bosses are fixedly connected to the outer sides of both the first and second support rods. A support mesh is mounted on the mounting bosses, which support the support mesh while simultaneously ensuring its stability after installation using bolts or other fasteners. A connecting plate is fixedly connected to the end of the telescopic rod furthest from the fixed rod. When the telescopic rod extends and retracts, causing the connecting plate to contact the sidewall of the pit, the connecting plate and the sidewall of the pit can be fixed together by fasteners. A limiting device on the telescopic rod restricts its extension and retraction, ensuring stable support between the backfilling device and the sidewall of the pit.

[0020] Compared with the prior art, this utility model rotatably mounts the main support on the base plate. When the backfilling device is installed in a pit with uneven ground, the rotation adjustment of the main support can keep the backfilling device vertical, making the installation of the backfilling device convenient. At the same time, by setting buffers at the connection points of the various components of the main support, the buffers effectively buffer the impact when the backfilling device is impacted by materials, reducing the displacement of the backfilling device caused by the impact of materials.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] As shown in Figures 1 to 3, the iron ore goaf filling device in one embodiment of this utility model includes a main body 1 and an auxiliary body 2.

[0033] As shown in Figures 1-3, the main structure 1 includes multiple extension rods 11 to allow for length adjustment based on the pit depth during use of the filling device. A top rod 12 is detachably mounted on each extension rod 11, serving as a support for the upper end of the filling device. The extension rods 11 and top rods 12 together form the main support of the backfilling device. A second sleeve 15 is fixedly connected to the top of each extension rod 11, and the bottom of the top rod 12 is installed within the second sleeve 15. The second sleeve 15 facilitates the installation between extension rods 11 and between extension rods 11 and top rods 12. A base plate 13 is mounted on the bottom of each extension rod 11, contacting the bottom surface of the backfill pit and providing bottom support for the backfilling device. A rotating seat is mounted on the base plate 13, and a first sleeve 14 is mounted on the rotating seat, allowing the first sleeve 14 to rotate. The lower end of the extension rod 11 is installed inside the first sleeve 14, allowing the extension rod 11 to be fixedly installed through the first sleeve 14. Rotation of the first sleeve 14 allows the extension rod 11 to rotate after installation. This enables the extension rod 11 to be adjusted in position when the base plate 13 is installed in an uneven pit, ensuring it remains vertical and facilitating the installation of the filling device. Furthermore, the rotation of the extension rod 11 eliminates the need to level the ground in contact with the base plate 13 during installation, further simplifying the backfilling device installation. Buffer pads 16 are installed on the inner walls of both the first sleeve 14 and the second sleeve 15. These buffer pads 16 cushion the impact of materials on the extension rod 11 and the top rod 12 installed within the first and second sleeves 14 and 15, preventing displacement of the backfilling device due to material impact.

[0034] As shown in Figures 1-4, the outer wall of the extension rod 11 inside the first sleeve 14 and the outer wall of the top rod 12 inside the second sleeve 15 both abut against the inner wall of the corresponding buffer pad 16. This allows the buffer pad 16 to effectively buffer the impact force received by the extension rod 11 and the top rod 12, thus achieving buffering when the backfilling device is impacted by materials. First fixing screws 17 are installed through the extension rod 11 and the first sleeve 14, as well as between the top rod 12 and the second sleeve 15, in a left-right through-type manner.

[0035] As shown in Figures 3 and 4, a locking nut 18 is installed on the threaded end of the first fixing screw 17. The locking nut 18 is a double nut combination. By restricting the first fixing screw 17 and the locking nut 18, the extension rod 11, the top rod 12, and the base plate 13 can be stably installed together, thereby ensuring the stability of the backfilling device structure. At the same time, the double nut design of the locking nut 18 effectively prevents the locking nut 18 from loosening when the backfilling device is impacted by materials, ensuring the stability of the connection structure.

[0036] Preferably, the cushioning pad 16 is made of rubber material with excellent impact resistance and weather resistance, which makes the cushioning pad 16 have excellent cushioning performance and a long service life.

[0037] As shown in Figure 5, the rotating seat includes a pair of mounting plates 19, which are fixedly connected to the base plate 13.

[0038] As shown in Figure 5, the first sleeve 14 is rotatably connected between a pair of mounting plates 19, and pivots 110 are fixedly connected to the outer sides of both the front and rear side walls of the first sleeve 14. Through the cooperation between the rotating seat formed by the pair of mounting plates 19 and the pivots 110, the first sleeve 14 is mounted on the base plate 13 and rotates while the structure is stable.

[0039] As shown in Figure 5, the pivot 110 is rotatably connected to the mounting plate 19 in a through manner. A buffer ring 111 is installed between the mounting plate 19 and the pivot 110. By setting the buffer ring 111, when the material impacts the backfilling device, the first sleeve 14 transmits the impact force to the mounting plate 19 through the pivot 110, and the impact force can be buffered by the buffer ring 111. In addition, the impact force received by the backfilling device is further buffered by the buffer ring 111.

[0040] As shown in Figures 1 and 2, the top of the top rod 12 is fixedly connected to the top plate 112, and the bottom of the bottom plate 13 is fixedly connected to multiple limiting protrusions 114. The limiting protrusions 114 allow the bottom plate 13 to be inserted into the pit when it is installed in the pit, and the limiting protrusions 114 prevent the second fixing screw 113 from moving laterally when it is installed in the pit.

[0041] As shown in Figures 1-3, the auxiliary mechanism 2 includes a first support rod 21, which is detachably mounted on the top rod 12. Second support rods 22 are hinged to both sides of the first support rod 21. Fixed rods 24 are hinged to the left and right side walls of the extension rod 11 and the top rod 12, and telescopic rods 25 are installed inside the fixed rods 24. The first support rod 21 and the second support rod 22 combine to form a planar support, providing shielding and protection for the pit surface and ensuring safe passage for workers.

[0042] As shown in Figures 1 and 2, the first support rod 21 is installed on the top plate 112, and a plurality of second fixing screws 113 are installed between the top plate 112 and the first support rod 21.

[0043] As shown in Figures 3 and 7, mounting bosses 27 are fixedly connected to the outer sides of both the first support rod 21 and the second support rod 22. The support net 23 is installed on the mounting bosses 27. The mounting bosses 27 support the support net 23 while bolts and other fasteners ensure the stability of the support net 23 after installation. A connecting plate 26 is fixedly connected to the end of the telescopic rod 25 away from the fixed rod 24. When the telescopic rod 25 extends and retracts, the connecting plate 26 contacts the side wall of the pit, and the connecting plate 26 and the side wall of the pit can be fixed by fasteners. The telescopic rod 25 is restricted from extension and retraction by a limiting device, so that there is a stable supporting force between the backfilling device and the side wall of the pit.

[0044] In use, the bottom extension rod 11 is installed inside the first sleeve 14 and locked by the cooperation of the first fixing screw 17 and the locking nut 18. The required number of extension rods 11 are installed on the extension rods 11 according to the depth of the backfill pit. A top rod 12 is installed on the uppermost extension rod 11. During installation, the bottom of the top rod 12 is installed inside the second sleeve 15 and locked by the cooperation of the first fixing screw 17 and the locking nut 18. Simultaneously, buffer pads 16 are provided inside both the first sleeve 14 and the second sleeve 15, ensuring that the bottoms of the extension rods 11 and the top rod 12 are in close contact with the buffer pads 16. The base plate 13 is placed in the pit, and downward pressure causes the limiting protrusion 11 at the bottom of the base plate 13 to... 4. Insert into the ground. When the base plate 13 is installed in an uneven pit, the main support consisting of the extension rod 11 and the top rod 12 is rotated to adjust the backfilling device so that it is installed vertically. Then, the telescopic rod 25 is extended so that the connecting plate 26 contacts the corresponding pit side wall. The connecting plate 26 is fixed to the pit wall by the fastener, and the telescopic rod 25 is ensured not to move by the limit device to complete the lateral support of the pit. The first support rod 21 is installed on the top rod 12 through the top plate 112, and the second support rods 22 on both sides of the first support rod 21 are unfolded. The edges of the second support rods 22 are stably supported by the pit side to complete the installation of the backfilling device.
