Technical Field

[0001] This invention relates to the technical field of coal mine production, and in particular to a coal chute lock structure. Background Technology

[0002] In daily mine production, coal chutes are indispensable production roadways. The lower lock of the coal chute, located at the lower opening of the coal chute, is an important means of controlling coal discharge. In the existing technology, the construction and installation of the lower lock of the coal chute is relatively complex. It requires cutting grooves on both sides of the lower opening of the coal chute, installing crossbeams, I-beams, and a shaft frame, and then spraying grout. The slope above the shaft frame is then constructed with sprayed grout, and the lock and coal discharge device are installed below the shaft frame to achieve the purpose of controlling coal discharge.

[0003] The above-mentioned lower locking method involves processes such as widening the side and excavating the trench, manually installing the I-beams and the well frame, shotcreting, and manually installing the locking components and coal discharge device. Normal construction takes eight days, resulting in a long construction period. Summary of the Invention

[0004] In view of this, the present invention provides a coal chute lock structure, which can reduce the construction period at the coal chute by prefabricating the components and fixing the anchoring components to the roadway roof to complete the construction of the coal chute, thereby reducing the number of procedures and shortening the construction period.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coal chute interlocking structure includes:

[0007] The upper panel has an anchoring assembly for extending into the roof of the roadway. The anchoring assembly is set at an angle to the upper panel and is located on the outside of the coal chute. The upper panel covers the opening edge of the coal chute.

[0008] A top liner is fixed to the top of the upper panel, the top liner covers the opening edge of the coal chute, and the anchoring assembly protrudes from the outside of the top liner;

[0009] A guide plate is fixed to the bottom of the upper panel. There are multiple guide plates connected end to end along the circumference to form a cylindrical structure with a large opening at the top and a small opening at the bottom.

[0010] The bottom plate is fixedly connected to all the guide plates and covers the bottom end of the guide plates in the longitudinal direction.

[0011] Preferably, the guide plate is fixed with an angle steel that covers the end of the guide plate, and the angle steel is fixed to the upper panel and the lower panel respectively.

[0012] Preferably, the guide plate includes an upper straight plate fixed to the upper panel, an inclined plate fixed to the upper straight plate, and a lower straight plate fixed to both the inclined plate and the lower panel, wherein the angle steel is fixed to the upper straight plate and the lower straight plate respectively.

[0013] Preferably, part of the upper straight plate is exposed from the bottom side of the angle steel, and part of the lower straight plate is exposed from the bottom side of the angle steel.

[0014] Preferably, the angle steel and the guide plate are connected by continuous welding to form a weld seam greater than or equal to the thickness of the upper straight plate and / or the thickness of the lower straight plate.

[0015] Preferably, the anchoring assembly includes an anchor rod perpendicular to the upper panel and an anchor cable disposed at an angle to the upper panel.

[0016] Preferably, the anchoring assembly further includes a sling mount fixed to the bottom of the upper panel, and the bottom ends of the anchor cable and anchor rod extend from below the sling mount.

[0017] Preferably, the upper panel and the anchor cable are set at an angle of 10 to 30 degrees.

[0018] Preferably, the guide plate is set at a 15-degree angle to the upper panel.

[0019] Preferably, a mortar structure is sprayed between the upper panel and the tunnel roof.

[0020] As can be seen from the above technical solution, the coal chute lock structure provided by the present invention, by prefabricating the upper panel, top liner, guide plate and lower panel and connecting the aforementioned components, can shorten the construction period at the coal chute. It is only necessary to move the aforementioned components after welding or fixing to the coal chute and fix the anchoring component in the expected position.

The following is in conjunction with... Figures 1 to 8 To explain.

[0035] The specific embodiments described below are intended to help those skilled in the art understand this embodiment, but this embodiment is not limited to the specific embodiments described below.

[0036] Reference Figure 1 and Figure 2 This disclosure provides an embodiment of a coal chute interlocking structure, which includes:

[0037] The upper panel 1 has an anchoring component 6 for extending into the roof of the roadway. The anchoring component 6 is set at an angle with the upper panel 1 and is located on the outside of the coal chute. The upper panel 1 covers the opening edge of the coal chute.

[0038] The top liner 2 is fixed to the top of the upper panel 1. The top liner 2 covers the opening edge of the coal chute, and the anchoring component 6 protrudes from the outside of the top liner 2.

[0039] Guide plate 5 is fixed to the bottom of upper panel 1. There are multiple guide plates 5 connected end to end along the circumference to form a cylindrical structure with a large opening at the top and a small opening at the bottom.

[0040] The bottom plate 3 is fixedly connected to all guide plates 5 and covers the bottom of the guide plates 5 in the longitudinal direction.

[0041] For example, refer to Figure 3 and Figure 4The upper panel 1 is a square plate structure with an opening in the middle. The anchoring component 6 includes an anchor rod 61 perpendicular to the upper panel 1, an anchor cable 62 at an angle to the upper panel 1, and a lifting mounting seat 63 fixed to the bottom of the upper panel 1. There are multiple lifting mounting seats 63, which are distributed at intervals around the edge contour of the upper panel 1. The positional distribution of the lifting mounting seats 63 fixed on the upper panel 1 is axially symmetrical. Each lifting mounting seat 63 corresponds to an anchor cable 62 or an anchor rod 61, and each anchor rod 61 corresponds to an anchor cable 62. That is, each anchor rod 61 fixed on the lifting mounting seat 63 and an anchor cable 62 fixed on another lifting mounting seat 63 form a group. The anchor rods 61 and anchor cables 62 forming the same group are fixed in the same area on the upper panel 1, so that two adjacent anchor rods 61 are separated by an anchor cable 62. Both the anchor cable 62 and the anchor rod 61 are fixed at the edge of the upper panel 1 via the lifting mounting base 63. The bottom ends of the anchor cable 62 and the anchor rod 61 extend from below the lifting mounting base 63, and the top ends of the anchor cable 62 and the anchor rod 61 extend above the upper panel 1 and are used to insert into the solid structure of the tunnel. The upper panel 1 is lifted and fixed by the anchor cable 62 and the anchor rod 61. The anchor cable 62 extends from the edge of the upper panel 1 to the outside of the upper panel 1, and the anchor cable 62 is set at an angle of 10 degrees to 30 degrees with the upper panel 1, for example, 20 degrees. The anchor rod 61 is set perpendicular to the upper panel 1. During the installation of the upper panel 1, a lifting anchor bolt 61 is constructed at the target position on the roof of the roadway below the coal chute. The upper panel 1 is then lifted to a position directly opposite the bottom of the coal chute using equipment such as an electric hoist. After adjusting the position of the upper panel 1 so that its central opening is aligned with the coal chute, the anchor bolt 61 is used to initially fix the upper panel 1. Then, anchor cables 62 are installed to further enhance the connection strength between the upper panel 1 and the roadway roof, ensuring that the upper panel 1 can maintain its current posture even after being impacted by the coal flow. In some embodiments, the roadway roof has poor flatness, resulting in numerous gaps between the upper panel 1 and the roadway roof. These gaps are filled by spraying mortar between the upper panel 1 and the roadway roof, thereby enhancing the connection stability between the upper panel 1 and the roadway roof and reducing the possibility of coal flow escaping through these gaps.

[0042] Reference Figure 5 and Figure 6The top liner 2 has the same shape as the upper panel 1 but is smaller in size. The top liner 2 is welded to the top surface of the upper panel 1, and the outline edge of the top liner 2 is located within the area enclosed by the outline edge of the upper panel 1. The central opening of the top liner 2 is aligned with the central opening of the upper panel 1. These two openings expose and connect the coal chute, and longitudinally cover the roadway structure at the edge of the coal chute. The function of the top liner 2 is to enhance the bending strength of the upper panel 1. The stress points of the anchor bolts 61 and anchor cables 62 on the upper panel 1 are located at the edge of the upper panel 1, and the load on the upper panel 1 is concentrated in the central area. Therefore, by welding the top liner 2 to the upper panel 1, the possibility of the upper panel 1 being subjected to impact or excessive bending under load can be reduced. Simultaneously, it can withstand the impact of coal flow after the roadway structure at the edge of the coal chute is damaged, reducing the possibility of direct impact of coal flow on the upper panel 1 and thus damage to the upper panel 1.

[0043] The guide plate 5 includes an upper straight plate 51 fixed to the upper panel 1, an inclined plate 52 fixed to the upper straight plate 51, and a lower straight plate 53 fixed to both the inclined plate 52 and the lower panel 3. Angle steel 4 is fixed to the upper straight plate 51 and the lower straight plate 53 respectively. The upper straight plate 51 is a vertically arranged rectangular plate structure. The top side of the upper straight plate 51 is welded to the bottom surface of the upper panel 1. When the central opening outline of the upper panel 1 and the top liner 2 is rectangular, the upper straight plate 51 has four pieces connected end to end along the circumference, forming a ring frame structure that matches the central opening outline of the upper panel 1 and the top liner 2. Each upper straight plate 51 corresponds to an inclined plate 52 and a lower straight plate 53. The inclined plate 52 is an isosceles trapezoidal plate structure inclined at a 15-degree angle relative to the upper straight plate 51. The lower straight plate 53 is a vertical rectangular plate structure. The top of the inclined plate 52 is fixed to the bottom side of the upper straight plate 51, and the bottom of the inclined plate 52 is fixed to the top side of the lower straight plate 53. Similarly, there are four inclined plates 52 and four lower straight plates 53, and adjacent inclined plates 52 or lower straight plates 53 are connected end to end to form a tubular structure fixed below the upper panel 1, centered on the coal chute, and with an opening that is larger at the top and smaller at the bottom. After the coal flows through the coal chute, it can enter the through channel formed by the guide plate 5 and then be transported to the target position.

[0044] The lower straight plate 53 has the same shape as the upper panel 1 but is smaller in size. The central opening of the lower panel 3 is smaller than the central opening of the upper panel 1 and is centered thereto. The bottom side of the lower straight plate 53 is welded to the top surface of the lower panel 3, and the lower straight plate 53 surrounds the edge of the opening on the lower panel 3. Angle steel 4 is fixed to the guide plate 5, covering the end of the guide plate 5. The angle steel 4 is fixed to the upper panel 1 and the lower panel 3 respectively. Part of the upper straight plate 51 protrudes from the bottom side of the angle steel 4, and part of the lower straight plate 53 protrudes from the bottom side of the angle steel 4. One side of the angle steel 4 is welded to the bottom surface of the upper panel 1, and the other side is welded to the outer wall of the upper straight plate 51. The angle steel 4 enhances the connection strength between the upper straight plate 51 and the upper panel 1, and adjacent angle steel 4 are connected end to end by welding. Similarly, one side of the angle steel 4 is welded to the bottom surface of the lower panel 3, and the other side is welded to the outer wall of the lower straight plate 53, thereby enhancing the connection strength between the lower straight plate 53 and the lower panel 3.

[0045] Additional references Figure 7 The inclined plate 52 has an inner end face facing the outer wall of the aforementioned through channel, and an outer end face facing away from the outer wall of the aforementioned through channel. The side wall of the inclined plate 52 used to connect to another inclined plate 52 extends inward, meaning the side wall of the inclined plate 52 and the outer end face of the inclined plate 52 are set at a 45-degree angle. Adjacent inclined plates 52 are perpendicular to each other, ensuring a tight fit between adjacent inclined plates 52, preventing gaps between them, and enhancing the connection strength between adjacent inclined plates 52. To reduce overall processing difficulty, the side wall of the inclined plate 52 perpendicular to the outer end face can also be retained, meaning it is not necessary to set the side wall of the inclined plate 52 at a 45-degree angle to the outer end face of the inclined plate 52. For example, additional reference... Figure 8 The upper straight plate 51, the lower straight plate 53, and the inclined plate 52 have the same thickness. The junction of two adjacent inclined plates 52 is formed by continuous welding to form a weld 41 with a thickness equal to that of the upper straight plate 51.

[0046] In this embodiment, the relative positional relationship between the lifting mounting base 63 and the top liner 2 can be varied. For example, the longitudinal projection of the lifting mounting base 63 can be located outside the edge of the longitudinal projection of the top liner 2, thus accommodating the large opening of the coal chute and making the area enclosed by the bottom ends of the anchor rods 61 and anchor cables 62 larger to meet the working conditions. Alternatively, the longitudinal projection of the lifting mounting base 63 can be cut off by the edge of the longitudinal projection of the top liner 2, that is, the area enclosed by the top ends of the anchor rods 61 and anchor cables 62 is smaller. This setting can reduce the possibility of bending of the upper panel 1 during continuous lifting, thereby improving its service life. This setting only requires adjusting the position so that the bottom ends of the anchor rods 61 and anchor cables 62 fixed on the lifting mounting base 63 can extend from the bottom end of the lifting mounting base 63, and the top ends of the anchor rods 61 and anchor cables 62 can extend from the top end of the lifting mounting base 63 and extend outward or upward from the edge of the top liner 2.

[0047] By prefabricating the upper panel 1, top liner 2, guide plate 5, and lower panel 3, and connecting the aforementioned components, the construction period at the coal chute can be shortened. Only the aforementioned components, after welding or fixing, need to be moved to the coal chute, and the anchoring component 6 needs to be fixed in the expected position. The installation of the aforementioned components is achieved by fixing the anchoring component 6 to the upper panel 1, thereby completing the construction at the coal chute and achieving the goal of reducing procedures and shortening the construction period.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
