[0001] This utility model relates to the field of mining engineering support technology, and in particular to a foldable roadway support for mining engineering. Background Technology

[0002] In mining engineering, the use of roadway support systems is essential. Firstly, mining operations are mostly conducted underground, and roadway excavation disrupts the original stress balance of the strata, leading to problems such as rock deformation and collapse. Roadway support systems can support the surrounding rock of the roadway, maintain the stable shape and space of the roadway, prevent roof collapse, sidewall spalling, and other accidents, and ensure the safety of miners and the normal operation of equipment.

[0003] However, roadway support supports are generally large in size. When installing large-sized roadway support supports, multiple sets of supports need to be manually moved to the designated position. During the process, the angle and position of the supports need to be repeatedly adjusted to ensure that they fit the shape of the roadway and the stress requirements. When multiple sets of supports are installed, the angle and position of each support need to be adjusted, which involves a lot of repetitive operations and is quite troublesome. To address this issue, a foldable roadway support support for mining engineering is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1-2 One embodiment of this utility model is a foldable roadway support for mining engineering, including a support 1, and a storage mechanism 2 is provided on the outer wall of the support 1; the storage mechanism 2 can be used to store and fold multiple sets of supports 1, thereby facilitating transportation.

[0033] Reference Figures 2-3The storage mechanism 2 includes a guide plate 201 fixedly connected to the outer wall of the bracket 1. A slider 202 is slidably connected to the outer wall of the guide plate 201. The guide plate 201 guides the slider 202, allowing it to move only vertically. Guide plates 201 are fixed on both the left and right sides of the bracket 1. An X-shaped connecting frame 207 is rotatably connected to the inner surface of the slider 202. One set of guide plates 201 corresponds to two sets of sliders 202. When the two sets of sliders 202 move towards the middle, the horizontal length of the X-shaped connecting frame 207 is extended, thereby completing the unfolding of the bracket 1. A positioning component 206 is provided on the front inner wall of the bracket 1. The positioning component 206 can fix the bracket 1 after it is unfolded or folded. The front surface of the bracket 1 is fixedly connected with the positioning post 203 and the connecting post 204. The positioning post 203 and the connecting post 204 are the same size. The connecting post 204 can cooperate with the positioning component 206 to fix the bracket 1 in the retracted state, thereby preventing the X-shaped connecting frame 207 from moving. The positioning post 203 can fix the rotatable positioning component 206 on the bracket 1 in the open state. The bottom inner wall of the bracket 1 is provided with a moving component 3, which facilitates the overall movement of the bracket 1.

[0034] Reference Figures 2-3 The positioning component 206 includes a rotating plate 2061 rotatably connected to the inner wall of the front part of the bracket 1. A movable plate 2062 is elastically connected to the inner wall of the rotating plate 2061 via a connecting spring 2063. Each set of rotating plates 2061 corresponds to two sets of connecting springs 2063 and their movable plates 2062. The elasticity of the connecting springs 2063 enables the movable plate 2062 to have reset and limit functions. A square groove is formed at the bottom of the rotating plate 2061, with the inner surface of the groove larger than the diameter of the positioning post 203. The cooperation between the square groove and the movable plate 2062 forms a square frame, which can accommodate the positioning post 203, thereby accommodating the rotating plate 2061. 1. The outer wall of the fixed movable plate 2062 is penetrated and slidably connected to the inner wall of the rotating plate 2061. The penetration facilitates manual movement of the movable plate 2062. The side of the movable plate 2062 away from the rotating plate 2061 is provided with an inclined surface. The inclined surface is provided to facilitate the movement of the movable plate 2062 when the rotating plate 2061 is rotated to a horizontal or vertical state. At this time, the positioning post 203 or the connecting post 204 presses against the inclined surface, thereby causing the movable plate 2062 to move, so that the square groove is outside the positioning post 203 or the connecting post 204. The cross-section of the guide plate 201 is concave. The concave design facilitates installation and fixation, and can move in conjunction with the slider 202.

[0035] Reference Figure 1 , Figure 4 and Figure 5The movable component 3 includes a protective plate 301 slidably connected to the inner wall of the bottom of the bracket 1. The protective plate 301 can move up and down and has a round hole for easy fixing with bolts during later installation. A magnetic strip 302 is fixedly connected to the outer wall of the protective plate 301. A magnetic plate 303 is fixedly connected to the bottom of the bracket 1 and a caster wheel 304 is fixedly connected to the bottom of the bracket 1. The magnetic properties of the magnetic plate 303 and the magnetic strip 302 can fix the protective plate 301 in the retracted state, and the caster wheel 304 is exposed at this time, which facilitates movement. The caster wheel 304 has a self-locking function, which is existing technology and will not be explained in detail here. The magnetic side of the magnetic plate 303 facing the magnetic strip 302 has opposite magnetic properties. The protective plate 301 is fixed in the retracted state by the principle of magnetic attraction between opposite poles. A receiving groove is opened at the bottom of the protective plate 301. The inner surface of the receiving groove is larger than that of the caster wheel 304. The receiving groove allows the caster wheel 304 to be covered and blocked after the protective plate 301 is installed.

[0036] Working principle: When bracket 1 needs to be retracted, the two sets of sliders 202 move up and down respectively, causing the horizontal length of the X-shaped connecting frame 207 to shorten, thus completing the retraction work, and bracket 1 folds accordingly. At this time, the rotating plate 2061 is in a vertical state, and the moving plate 2062 extends under the elastic action of the connecting spring 2063. When bracket 1 is completely folded, the rotating plate 2061 is rotated to a horizontal state and contacts another set of connecting columns 204. The connecting column 204 contacts and presses against the inclined surface of the moving plate 2062, pushing the moving plate 2062 to retract inward into the rotating plate 2061. The square groove is outside the connecting column 204, and the rotating plate 2061 can rotate to fit against the inner wall of bracket 1. The moving plate 2062 is reset again under the action of the connecting spring 2063, locking the connecting column 204, fixing the retracted bracket 1, and preventing the X-shaped connecting frame 207 from moving. When it is necessary to unfold the bracket 1, move the moving plate 2062 outward, and then rotate the rotating plate 2061 in the opposite direction to make it vertical and make it contact and cooperate with the positioning column 203 to fix the rotating plate 2061. Then, multiple sets of brackets 1 can be pulled apart to complete the installation work.

[0037] When the support frame 1 is in its retracted state, the magnetic plate 303 and magnetic strip 302 attract each other due to their opposite magnetic properties, attracting the protective plate 301 to the inner bottom wall of the support frame 1, exposing the caster wheel 304. Since the caster wheel 304 has a self-locking function, unlocking it allows the support frame 1 to be moved as a whole, facilitating transportation and position adjustment within the mining tunnel. Once the support frame 1 has moved to the designated position, if it needs to be fixed, push the protective plate 301 downwards to release it from the magnetic plate 303's attraction. The receiving groove at the bottom of the protective plate 301 will then cover and shield the caster wheel 304. At this point, the support frame 1 can be fixed to the tunnel floor using bolts through the round holes on the protective plate 301, ensuring the support frame 1 remains stable and does not move during support operations.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
