Detailed Implementation

[0021] The technical solutions of the present invention 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 invention, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] This application provides a mine slope protection device, including two mounting components, a steel cable 6, and a protective net 7. The two mounting components are spaced apart along a first direction. Each mounting component includes a base 2, a connecting component 4, and a shock absorber 5. The base 2 is connected to the slope 1 and has a slide rail 3 extending along the first direction. The connecting component 4 is slidably connected to the slide rail 3. The shock absorber 5 is connected to the base 2 and includes a movable end that can move along the first direction, and the movable end is connected to the connecting component 4. The steel cable 6 is connected to the connecting component 4 of the two mounting components, and the protective net 7 is connected to the steel cable 6.

[0024] The specific structure of the base 2 fixed to the slope 1 can be selected from the existing structures, and will not be described in detail here.

[0025] The first direction can be the direction shown by the X-axis in the figure, and the first direction can be parallel to the horizontal plane.

[0026] The specific structure of the shock absorber 5 is well known to those skilled in the art and will not be described in detail here. In summary, when the shock absorber 5 is working, the movable end of the shock absorber 5 can float within a certain range to play a buffering role, and the movable end can return to its original position after the external force on the movable end disappears.

[0027] The steel cable 6 is used to support the protective net 7, so that the protective net 7 can be stretched. When there are falling objects on the slope 1, the protective net 7 can catch the falling objects and prevent them from falling further.

[0028] When a falling object lands on the protective net 7, the protective net 7 deforms. The external force on the protective net 7 is transmitted to the steel cable 6. The steel cable 6 pulls the connecting parts 4 to move, causing the two connecting parts 4 to close together. When the connecting parts 4 move, they can drive the movable end to move. The movable end buffers the external force, reducing the risk of the protective net 7 being damaged by the impact of the falling object.

[0029] In this embodiment, the two mounting components can be arranged symmetrically.

[0030] In some embodiments, multiple steel cables 6 are provided, and the multiple steel cables 6 are spaced apart along a second direction, which is perpendicular to the first direction.

[0031] The second direction can be the direction shown by the Y-axis in the figure, or it can be parallel to the horizontal direction.

[0032] By setting multiple steel cables 6, the protective net 7 can be fully stretched, increasing the working area of ​​the protective net 7.

[0033] In some embodiments, the connecting component 4 includes a sliding part 18, a first shaft 10, and a plurality of first sliding sleeves 11. The sliding part 18 is slidably connected to the slide rail 3, the first shaft 10 is connected to the sliding part 18, the plurality of first sliding sleeves 11 are sleeved on the first shaft 10, a first elastic element 12 is provided between two adjacent first sliding sleeves 11, and the steel cable 6 is connected to the first sliding sleeve 11 in a corresponding manner.

[0034] The specific cooperation method between the sliding part 18 and the slide rail 3 is known to those skilled in the art and will not be described in detail here.

[0035] The first sliding sleeve 11 is sleeved on the first shaft 10, so that the first sliding sleeve 11 can move along the axial direction of the first shaft 10, thereby allowing the spacing between the first sliding sleeves 11 to be adjusted.

[0036] The first elastic element 12 can enable the first sliding sleeve 11 to return to its original position after the first sliding sleeve 11 is closed.

[0037] When a falling object is caught on the protective net 7, a portion of the protective net 7 protrudes. At this time, the deformation of the protective net 7 can exert force on multiple steel cables 6, causing multiple first sliding sleeves 11 to close, and then the steel cables 6 can also close. This allows the two sides of the protective net 7 along the second direction to close, while the middle protrudes downward, reducing the risk of falling objects from the protective net 7.

[0038] In some embodiments, the first elastic element 12 is a spring, and the first elastic element 12 is sleeved on the first shaft 10.

[0039] The first elastic element 12 is sleeved on the first shaft 10, which on the one hand enables the first elastic element 12 to play a resetting role on the first sliding sleeve 11, and on the other hand reduces the risk of the first elastic element 12 falling off the first shaft 10.

[0040] In some embodiments, reinforcing ribs are provided at the corners of the sliding portion 18 and the first shaft 10.

[0041] The reinforcing ribs increase the connection strength between the sliding part 18 and the first shaft 10, reducing the risk of deformation of the first shaft 10 under the action of the steel cable 6.

[0042] In some embodiments, along the axial direction of the first shaft 10, one end of the first shaft 10 is provided with an abutment portion 13, and the other end is provided with a locking portion, and a plurality of first sliding sleeves 11 are disposed between the abutment portion 13 and the limiting portion.

[0043] The abutment part 13 and the limiting part cooperate to limit the first sliding sleeve 11, reducing the risk of the first sliding sleeve 11 falling off the first shaft 10.

[0044] In some embodiments, the limiting part includes a pin 14, and the first shaft 10 is provided with a pin hole, into which the pin 14 is inserted.

[0045] The pin 14 allows the first sliding sleeve 11 to be detachably connected to the first shaft 10. When the pin 14 is pulled out of the pin hole, the first sliding sleeve 11 and the first elastic element 12 can be removed from the first shaft 10. Conversely, when the first sliding sleeve 11 and the first elastic element 12 are installed on the first shaft 10, inserting the pin 14 into the pin hole prevents the first sliding sleeve 11 and the first elastic element 12 from being removed from the first shaft 10.

[0046] In some embodiments, a plurality of lifting rings 8 are provided in the middle of the steel cable 6, the steel cable 6 is passed through the lifting rings 8, and the protective net 7 is connected to the lifting rings 8.

[0047] The middle part of steel cable 6 refers to the portion between the two ends of steel cable 6.

[0048] The two ends of the protective net 7 are connected to the steel cable 6 and cannot move relative to the steel cable 6. Under the action of the lifting ring 8, on the one hand, the supporting effect of the steel cable 6 on the protective net 7 is increased, and on the other hand, the middle part of the protective net 7 can deform within a certain range relative to the steel cable 6, further reducing the risk of damage to the protective net 7 under external impact.

[0049] In some embodiments, a plurality of support components 9 are further provided between the two mounting components. The plurality of support components 9 are arranged along a first direction. Each support component 9 includes a second shaft 15 and a plurality of second sliding sleeves 16. The second shaft 15 is connected to the slope 1. The plurality of second sliding sleeves 16 are fitted onto the second shaft 15. A second elastic element 17 is provided between two adjacent second sliding sleeves 16. The second sliding sleeves 16 are provided with through holes, and steel cables 6 are correspondingly threaded through the through holes.

[0050] The connection method between the second shaft 15 and the slope 1 can be selected from the existing connection methods, which will not be elaborated here.

[0051] The second sliding sleeve 16 is fitted onto the second shaft 15, so that the second sliding sleeve 16 can move relative to the second shaft 15.

[0052] The second elastic element 17 can be a spring, or it can be sleeved on the second shaft 15.

[0053] The second elastic element 17 is used to provide an elastic force that allows the second sliding sleeve 16 to return to its original position after closing.

[0054] The perforation of the second sliding sleeve 16 is used for the steel cable 6 to pass through, so that when multiple steel cables 6 are closed, the distance between the second sliding sleeves 16 can also be reduced.

[0055] It should be noted that in the embodiment where the steel cable 6 is provided with a lifting ring 8, the distance between the lifting ring 8 and the second sliding sleeve 16 needs to be set reasonably to reduce the risk of the second sliding sleeve 16 hindering the deformation of the protective net 7.

[0056] The second shaft 15 can be the same as the first shaft 10, with abutment 13 and pin 14 respectively provided at both ends of the axial direction to limit the second sliding sleeve 16.

[0057] In some embodiments, one end of the second shaft 15 is pointed.

[0058] The pointed end of the second shaft 15 facilitates the connection of the second shaft 15 to the slope 1. For example, the second shaft 15 can be inserted into the slope 1 so that the second shaft 15 can be connected to the slope 1.

[0059] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, changes, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
