Abstract
Description
Technical Field
[0001] This application relates to the field of coal mine roadway equipment technology, and in particular to a height-adjustable suspension device for coal mine roadways. Background Technology
[0002] The pipe hooks used for suspending various pipelines in current coal mine roadways include mining plastic steel pipe hooks made of PVC material, galvanized chains, and pipe hooks made of round steel with a diameter of 5-24mm.
[0003] Among them, PVC-made mining plastic-steel pipe hooks are only used to suspend various cables. Due to the heavy weight of coal mine water supply and drainage pipes, and the high-pressure liquid flowing at high speed inside the pipes during normal use, the pipeline will experience significant vibration. Therefore, these hooks are not very sturdy and durable and are prone to breakage. As a result, coal mining enterprises rarely use them to suspend water supply and drainage pipelines. Galvanized chains are generally used for temporary suspension of water supply and drainage pipelines. However, when used to suspend pipelines, it is difficult to achieve a uniform standard spacing between each pipeline. The spacing is almost entirely determined by the installer's experience. At the same time, the chain itself is limited by the different sizes of the chain links, making it difficult to adjust to a uniform spacing. Pipe hooks are the most common type. They are generally processed and manufactured by coal mining enterprises themselves and are widely used for suspending water supply and drainage pipelines in coal mine roadways. However, once these hooks are manufactured, the pipeline spacing is fixed. When there is a large slope in the roadway, it is difficult to adjust the installation height of the pipeline in a timely manner according to the slope change. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, this utility model provides a height-adjustable hanging device for coal mine roadways, including: a mounting rod assembly, one end of which extends into the upper wall of the roadway;
[0006] An adjusting member is connected to the mounting rod assembly and is movable in the vertical direction of the mounting rod assembly;
[0007] The hook component has an arc-shaped hook for hanging.
[0008] The adjusting member and the hook member are connected through the connecting member.
[0009] In one feasible implementation, the mounting rod assembly includes:

[0014] The eye nut has a rated load of 1 ton and is model M18.
[0015] In one feasible implementation, the adjusting member is a rotatable nut, which is threadedly connected to the threaded steel anchor rod without longitudinal reinforcement.
[0016] In one feasible implementation, the connector is a right angle iron, which has a horizontal plane and a vertical plane. A circular hole is provided on the horizontal plane. The connector passes through the circular hole into the threaded steel anchor rod without longitudinal reinforcement, and the adjusting member is located below the right angle iron.
[0017] The vertical plane is located above the horizontal plane.
[0018] In one feasible implementation, the hook has a plurality of pipe hooks arranged sequentially from top to bottom, and the top end of the hook is connected to the vertical surface.
[0019] In one feasible implementation, the hook includes:
[0020] A strip angle iron, wherein the strip angle iron is disposed on the inside side of the right angle formed by the right angle iron;
[0021] Cable hooks, which are spaced apart along the strip angle iron;
[0022] The cable hook has a straight rod and several hook bodies, one end of the straight rod is connected to the strip angle iron, and the hook bodies are arranged longitudinally along the straight rod.
[0023] In one feasible implementation, the hook is a φ18*24mm round steel bar, and the total length of the hook is between 300-600mm.
[0024] In one possible implementation, the mounting rod assembly further includes:
[0025] A limiting block is provided at the lower end of the threaded steel anchor rod without longitudinal reinforcement.
[0026] In one feasible implementation, it further includes:
[0027] A fastening bolt is threadedly connected to the threaded steel anchor rod without longitudinal reinforcement, and the fastening bolt is located on the lower side of the adjusting member.
[0028] Compared with the prior art, this utility model has at least the following beneficial effects: one end of the mounting rod assembly extends into the upper wall of the tunnel, and the hanging device is connected to the upper wall of the tunnel through the mounting rod assembly to realize the hanging function; the adjusting member is connected to the mounting rod assembly and can be adjusted up and down in the vertical direction of the mounting rod assembly; the hook member has a hook, and the pipelines and lines to be hung are set on the hook member to realize the hanging of pipelines and lines; the connecting member is used to connect the hook member and the adjusting member, so that when the height of the adjusting member changes, the height of the hook member can also be changed.
[0029] This technical solution addresses the shortcomings of commonly used round steel hooks in coal mine roadways.

[0038] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.
[0039] like Figure 1-4 As shown in the embodiment of this application, a height-adjustable suspension device for coal mine roadways is proposed, comprising: a mounting rod assembly 100, one end of which extends into the upper wall of the roadway; an adjusting member 200 connected to the mounting rod assembly 100, the adjusting member 200 being movable in the vertical direction of the mounting rod assembly 100; a hook member 300 having an arc-shaped hook for achieving the suspension function; and a connecting member 400, through which the adjusting member 200 and the hook member 300 are connected.
[0040] The height-adjustable suspension device for coal mine roadways provided in this application includes a mounting rod assembly 100, an adjusting component 200, a hook component 300, and a connecting component 400.
[0041] The mounting rod assembly 100 has one end extending into the upper wall of the tunnel. This hanging device is connected to the upper wall of the tunnel through the mounting rod assembly 100, thereby realizing the hanging function. The adjusting member 200 is connected to the mounting rod assembly 100 and can be adjusted up and down in the vertical direction of the mounting rod assembly 100. The hook member 300 has a hook, and the pipelines and lines to be hung are set on the hook member 300, so that the pipelines and lines can be hung. The connecting member 400 is used to connect the hook member 300 and the adjusting member 200, so that when the height of the adjusting member 200 changes, the height of the hook member 300 can also change.
[0042] This technical solution addresses the shortcomings of commonly used round steel hooks in coal mine roadways. Specifically, by employing an adjustable height device, the installation height of the hooks can be conveniently adjusted as the roadway slope changes to meet actual work requirements, eliminating the need for specially sized hanging devices. This improves work efficiency and enhances the standardization of safety production in roadways.
[0043] like Figure 1-4 As shown, the mounting rod assembly 100 includes: a suspended anchor rod 110, one end of which is driven into the top of the roadway; a lifting eye nut 120, which is connected to the other end of the suspended anchor rod 110; and a threaded steel anchor rod 130 without longitudinal reinforcement, the entire rod body of which is threaded, and one end of which has an installation hook.
[0044] The suspended anchor rod 110 is a round steel anchor rod with a specification of φ18*2100mm; the lifting eye nut 120 has a rated load of 1 ton and is model M18.
[0045] In this technical solution, the installation rod assembly 100 includes a hanging anchor rod 110 and a lifting eye nut 120. In practical applications, the hanging anchor rod 110 is pre-installed during tunnel excavation, or pre-installed in the later stages of tunnel formation according to the required location of the suspended pipeline.
[0046] The lower end of the hanging anchor rod 110 has threads on its outer surface. The eye nut 120 is connected to the hanging anchor rod 110 by the nut thread. The bent end of the threaded steel anchor rod 130 without longitudinal reinforcement can extend into the eye nut 120, thereby realizing the connection between the threaded steel anchor rod 130 without longitudinal reinforcement and the eye nut 120.
[0047] In this technical solution, the threaded steel anchor rod 130 without longitudinal reinforcement and the lifting eye nut 120 are non-rigidly connected, which allows for free adjustment of the angle of the threaded steel anchor rod without longitudinal reinforcement. It can adapt to different angles of the pipeline to be suspended and can provide only the horizontal upward force to the pipeline to be suspended.
[0048] like Figure 1-4 As shown, the adjusting component 200 is a rotatable nut, and the adjusting component 200 is threadedly connected to the threaded steel anchor rod 130 without longitudinal reinforcement.
[0049] In this technical solution, the outer surface of the threaded steel anchor rod 130 without longitudinal reinforcement has threads, and the adjusting component 200 is a rotatable nut. The adjusting component 200 is threadedly connected to the threaded steel anchor rod 130 without longitudinal reinforcement. When the adjusting component 200 moves up and down on the threaded steel anchor rod 130 without longitudinal reinforcement by rotating, the horizontal height of the hook component 300 can be adjusted.
[0050] like Figure 1-4 As shown, the connector 400 is a right angle iron, which has a horizontal surface and a vertical surface. The horizontal surface has a circular hole, through which the connector 400 passes through the threaded steel anchor rod 130 without longitudinal reinforcement, and the adjusting member 200 is located below the right angle iron; the vertical surface is located above the horizontal surface.
[0051] In this technical solution, the connector 400 is a right-angle iron with a round hole on one side. During use, one end of the threaded steel anchor rod 130 without longitudinal reinforcement passes through the right-angle iron, and the right-angle iron is located at the upper end of the adjusting member 200. After the adjusting member 200 is adjusted to a horizontal height by rotation, the lower end of the right-angle iron abuts against the adjusting member 200, and the hook member 300 is connected to the right-angle iron, thereby realizing the adjustment of the height of the hook member 300.
[0052] like Figure 1-4 As shown, the hook 300 has a plurality of pipe hooks arranged sequentially from top to bottom, and the top end of the hook 300 is connected to the vertical surface.
[0053] In this technical solution, when it is necessary to suspend the pipe, it is suspended by arranging several pipe hooks in sequence.
[0054] In this embodiment, the hook 300 and the connector 400 are connected by welding.
[0055] like Figure 1-4 As shown, the hook component 300 includes: a strip angle iron, which is disposed on the inside of the right angle formed by the right angle iron; a cable hook, which is spaced apart along the strip angle iron; the cable hook has a straight rod and a plurality of hook bodies, one end of the straight rod is connected to the strip angle iron, and the hook bodies are arranged longitudinally along the straight rod.
[0056] In this technical solution, when communication and power cables need to be suspended, a strip of iron and a hook 300 with a cable hook at the bottom are used for suspension. Since the connector 400 is a right angle iron, the right angle iron has a right angle and its vertical surface is located at the upper end of the horizontal plane. Therefore, the right angle iron can form a space that can place the strip of iron, thereby fixing the hook 300.
[0057] like Figure 1-4 As shown, the hook 300 is a φ18*24mm round steel bar, and the total length of the hook 300 is between 300-600mm.
[0058] In this technical solution, specifically in this embodiment, the pipe is suspended using four-link round steel hooks. φ18*24mm round steel bars are selected, with a total length between 300-600mm. This embodiment is the main implementation of the suspension device, used to suspend different types and materials of pipes such as water supply pipes, drainage pipes, compressed air pipes, grouting pipes, and nitrogen injection pipes in coal mines. One set of this device is installed every three meters, and its height can be flexibly adjusted.
[0059] like Figure 1-4 As shown, the mounting rod assembly 100 further includes a limiting block 500, which is disposed at the lower end of the threaded steel anchor rod 130 without longitudinal reinforcement.
[0060] In this technical solution, since the adjusting component 200 can move up and down the mounting rod assembly 100, in order to prevent the adjusting component 200 from falling off the mounting rod assembly 100, a limiting block 500 is added. The limiting block 500 is set at the lower end of the threaded steel anchor rod 130 without longitudinal reinforcement to prevent the adjusting component 200 from falling off due to excessive adjustment or thread wear.
[0061] like Figure 1-4 As shown, it also includes: a fastening bolt 600, which is threadedly connected to the threaded steel anchor rod 130 without longitudinal reinforcement, and the fastening bolt 600 is disposed on the lower side of the adjusting member 200.
[0062] In this technical solution, the hanging device is equipped with a fastening bolt 600, which is also threaded to the threaded steel anchor rod 130 without longitudinal reinforcement and is located at the lower end of the adjusting member 200. During use, after the adjusting member 200 is adjusted to a suitable position, the fastening bolt 600 is rotated so that the fastening bolt 600 abuts against the lower end of the adjusting member 200.
[0063] This fastening bolt 600 can share the pressure of the adjusting member 200 and reduce the rotational misalignment of the adjusting member 200 due to pressure.
