Description

Technical Field

[0001] This utility model relates to the field of coal mine support technology, and more specifically, to a column filler. Background Technology

[0002] In fully mechanized coal mining faces, hydraulic supports are crucial equipment for ensuring roof safety. The base of the hydraulic support column is mounted on the support base via a column socket. After actual assembly, a ring-shaped gap exists between the column and the column socket on the base.

[0003] Currently, during production, coal chunks, coal dust, and other debris easily fall into and accumulate in the column socket through this gap. The traditional solution is to seal the gap with filler. While this filler prevents debris from falling directly to the bottom of the column socket, its top itself becomes a dust accumulation platform, causing coal slag and coal dust to pile up on top of the filler. This not only affects the cleanliness and standardization of the workface but also requires frequent manual cleaning by operators, increasing labor intensity and consuming valuable production time.

[0004] In summary, the existing column filling materials are prone to coal accumulation, increasing the labor intensity of workers, which is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a column filler that allows carbon blocks and coal dust to slide naturally off the column socket of the hydraulic support in the coal mining face, reducing the intensity of sanitation work, saving working time, and improving the standardization of the site.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A column filler is used to be disposed above a column recess in a support base, the column recess being used to install a column, the column filler comprising:

[0008] The filling material body is used to cover the gap between the bracket base and the column;

[0009] The top of the filling body is provided with a roof structure; the roof structure includes interconnected inclined surfaces so that coal ash falling from above the roof structure slides down along the inclined surfaces.

[0010] The mounting groove extends through the filling material body; the column filling material is fitted onto the column through the mounting groove.

[0011] Optionally, the filling material body is interference-fitted with the side wall of the column through the mounting groove; and / or, the filling material body is provided with a receiving groove communicating with the mounting groove, the receiving groove being used to receive hydraulic lines.

[0012] Optionally, the inclined surface includes a first inclined surface and a second inclined surface; the first inclined surface and the second inclined surface are connected to each other; the intersection of the first inclined surface and the second inclined surface is located at the uppermost part of the filling material body.

[0013] Optionally, the column filler has a plane of symmetry; the intersection of the first inclined surface and the second inclined surface lies on the plane of symmetry; the first inclined surface and the second inclined surface are symmetrical about the plane of symmetry.

[0014] Optionally, the outer surface of the column filler includes:

[0015] A first facade connected to the first inclined surface; the extension direction of the first facade is parallel to the extension direction of the column;

[0016] A second facade connected to the second inclined surface; the second facade is parallel to the first facade.

[0017] Optionally, the outer surface of the column filler includes:

[0030] 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.

[0031] The core of this utility model is to provide a column filler that allows carbon blocks and coal dust to slide naturally off the column socket of the hydraulic support in the coal mining face, reducing the intensity of sanitation work, saving working time, and improving the standardization of the site.

[0032] Please refer to Figures 1 to 5In this embodiment, the column filler is used to be placed above the column socket of the support base 11. The column socket is used to install the column. The column filler includes: a filler body 1 for covering the gap between the support base 11 and the column; a roof structure 2 is provided on the top of the filler body 1; the roof structure 2 includes interconnected inclined surfaces so that coal slag falling from above the roof structure 2 slides down along the inclined surfaces; and an installation groove 4 that penetrates the filler body 1. The column filler is fitted onto the column 5 through the installation groove 4.

[0033] It should be noted that a problem with existing coal support operations is how to prevent coal slag from accumulating on top of the column filler, thereby reducing cleaning work. To solve this problem, this embodiment provides a column filler that changes the traditional flat-top design to a "roof structure".

[0034] Please refer to Figure 1 and Figure 2 The column filler mainly comprises a filler body 1. Preferably, the filler body 1 is made of foamed polyurethane material, which has low density and light weight, making it easy to carry and install downhole. A roof structure 2 is provided on the top of the filler body 1, which is composed of interconnected inclined surfaces. When coal slag falls from above, it will slide down these inclined surfaces due to gravity and will not accumulate at the top. Furthermore, a through mounting groove 4 is provided on the filler body 1, allowing the entire filler to be easily fitted onto the column 5 like a collar, facilitating installation.

[0035] In summary, this technical solution directly solves the problem of coal accumulation on flat roofs through the innovative roof structure design, enabling coal slag to slide off automatically, significantly reducing the number of manual cleaning operations and labor intensity, and improving the standardization level of the working face.

[0036] Furthermore, the filling material body 1 is interference-fitted with the side wall of the column 5 through the mounting groove 4; and / or, the filling material body 1 is provided with a receiving groove 3 communicating with the mounting groove 4, the receiving groove 3 being used to receive the hydraulic pipeline 13.

[0037] In practical applications, in order to ensure that the filling material can be stably installed in the complex vibration environment downhole, and to take into account the layout of hydraulic pipelines, this utility model provides a further optimization scheme.

[0038] As attached Figure 5 As shown, the filling material body 1 can achieve an interference fit with the side wall of the column 5 through the mounting groove 4. This tight fit effectively prevents the filling material from loosening and falling off during use, ensuring its long-term reliability.

[0039] Alternatively, in an alternative embodiment, the filling material body 1 may also be provided with a receiving groove 3 communicating with the mounting groove 4. This receiving groove 3 is specifically designed to accommodate the hydraulic pipeline 13. This design cleverly embeds the pipeline inside the filling material, avoiding a cluttered arrangement of pipelines on the outside. This not only makes the overall structure more compact but also protects the pipelines from external impacts, improving the system's safety and tidiness. It should be noted that the interference fit and the inclusion of the receiving groove 3 can be implemented individually or in combination to address different on-site requirements.

[0040] In some embodiments, the inclined surface includes a first inclined surface 6 and a second inclined surface 7; the first inclined surface 6 and the second inclined surface 7 are connected to each other; the intersection of the first inclined surface 6 and the second inclined surface 7 is located at the uppermost part of the filling body 1.

[0041] To improve the airflow guiding effect of the roof structure 2, this embodiment defines its specific shape. Specifically, the inclined surface includes a first inclined surface 6 and a second inclined surface 7.

[0042] Please refer to Figure 2 and Figure 4 The first inclined surface 6 and the second inclined surface 7 are connected to each other, and their intersection line is located at the uppermost part of the filling body 1, forming a ridge-like highest line. This double-sloped roof design allows coal slag falling from any direction to be guided to slide down to both sides, resulting in high diversion efficiency and preventing the formation of coal accumulation dead zones.

[0043] Furthermore, the column filler has a plane of symmetry; the intersection of the first inclined surface 6 and the second inclined surface 7 lies on the plane of symmetry; the first inclined surface 6 and the second inclined surface 7 are symmetrical about the plane of symmetry.

[0044] In one embodiment, to facilitate manufacturing and installation, and to ensure a balance between mechanical properties and flow guidance effect, the column filler is designed to have a symmetrical plane. The intersection of the first inclined surface 6 and the second inclined surface 7 lies precisely on this symmetrical plane, and the first inclined surface 6 and the second inclined surface 7 are symmetrical about this symmetrical plane. This symmetrical design makes the filler more evenly stressed and has a more regular appearance. Furthermore, it eliminates the need to distinguish a specific direction during use, making installation more convenient.

[0045] Preferably, the outer surface of the column filler includes: a first facade 8 connected to the first inclined surface 6; the extension direction of the first facade 8 is parallel to the extension direction of the column 5; a second facade 9 connected to the second inclined surface 7; and the second facade 9 is parallel to the first facade 8.

[0046] This device can have a more regular shape to better match the structure of the support base 11. Please refer to... Figures 1 to 3 The outer surface of the column filler also includes a first facade 8 and a second facade 9. The first facade 8 is connected to the first inclined surface 6, and the second facade 9 is connected to the second inclined surface 7. The extension directions of both the first facade 8 and the second facade 9 are parallel to the extension direction of the column 5 and are parallel to each other. These two facades constitute the two main sides of the filler body, making its structure more regular and easier to process and shape.

[0047] In some embodiments, the outer surface of the column filler includes:

[0048] The third facade 10 is connected to the ends of the first inclined surface 6, the second inclined surface 7, the first facade 8, and the second facade 9; the fourth facade is connected to the ends of the first inclined surface 6, the second inclined surface 7, the first facade 8, and the second facade 9 away from the third facade 10.

[0049] To form a complete hexahedral structure, the outer surface of the column filler further includes a third facade 10 and a fourth facade. (See attached...) Figure 2 As shown, the third facade 10 is connected to one end of the first inclined surface 6, the second inclined surface 7, the first facade 8, and the second facade 9. The fourth facade is connected to the other end of these surfaces away from the third facade 10. The third facade 10 and the fourth facade together form the two end faces of the infill, making it a closed and structurally stable whole. The overall structure is easy to grasp and highly operable.

[0050] Furthermore, when the column filler is fitted onto the column 5, the first facade 8, the second facade 9, the third facade 10, and the fourth facade are all flush with the side of the support base 11.

[0051] It should be noted that when the column filler is fitted onto the column 5 and correctly installed, its outer surface, including the first elevation 8, the second elevation 9, the third elevation 10, and the fourth elevation, is flush with the side of the support base 11. This design allows the filler to be perfectly embedded in the structure of the support base 11 without creating any additional protrusions or depressions, ensuring the overall flatness and aesthetics of the working surface and avoiding potential scratches caused by protruding filler.

[0052] Furthermore, the column filler in this embodiment is applied to a hydraulic support system, which includes a support base 11, a column 5, and the aforementioned column filler. The column filler fills the column recess gap between the column 5 and the support base 11.

[0053] Please refer to Figure 5 The hydraulic support system includes a support base 11, a column 5, and the aforementioned column filler. The column filler fills the gap in the column socket between the column 5 and the support base 11. By using a filler with a roof structure, the entire hydraulic support system can effectively avoid the problem of frequent cleaning due to coal slag accumulation in the column socket area during operation, thus improving the continuous operating efficiency of the system and the standardization of the working environment.

[0054] Furthermore, there are multiple support bases 11, which are arranged at intervals; there are multiple columns 5, which are arranged one-to-one with the multiple support bases 11; there are multiple column fillers, which are arranged one-to-one with the multiple columns 5.

[0055] In practical applications, a complete hydraulic support system typically consists of multiple support units arranged side-by-side. Therefore, in this embodiment, there are multiple support bases 11, which are spaced apart. Correspondingly, there are also multiple uprights 5 and upright fillers, each corresponding to one of the support bases 11. This arrangement ensures that each upright socket of the entire row of hydraulic supports is effectively protected, achieving comprehensive cleaning of the working surface.

[0056] In some embodiments, the hydraulic support system includes a base box 14; a plurality of support bases 11 are arranged at intervals along a preset direction on the base box 14; the top of the column filler is provided with a first inclined surface 6 and a second inclined surface 7; the intersection line of the first inclined surface 6 and the second inclined surface 7 extends along the preset direction.

[0057] To optimize the flow direction and better suit the layout of the working face, the hydraulic support system includes a base box 14, on which multiple support bases 11 are spaced apart along a preset direction. In this configuration, the intersection of the first inclined surface 6 and the second inclined surface 7 at the top of the column filler is set to extend along this preset direction. This layout allows coal slag to effectively slide down the inclined surfaces into the channels between the supports, facilitating centralized cleaning or unified treatment by a cleaning device, further improving cleaning efficiency.

[0058] In addition, it should be noted that the orientation or positional relationship indicated by "horizontal", "vertical", etc. in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
