Description

Technical Field

[0001] The utility model relates to the technical field of geological survey support, in particular to a geological survey anti-collapse support device. Background Art

[0002] "Geological exploration" refers to the investigation and research activities that use various means and methods to survey and explore the geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters. It is the investigation and research of the geological conditions of a specific area, including rocks, strata, structure, mineral resources, hydrology, and landforms, to determine the quality and quantity of industrially significant mineral deposits discovered during mineral surveys, and to provide the mineral reserves and geological data needed for mine construction design in order to determine the quality and quantity of the minerals, the technical conditions for mining and utilization, and provide the mineral reserves and geological data needed for mine construction design.

[0003] In order to stabilize tunnels or mines during exploration, certain anti-collapse equipment is needed to prevent landslides and provide time for personnel to evacuate.

[0004] The existing patent (publication number: CN217501725U) is a collapse prevention device for geological exploration, including a top plate, which is used to support the top wall. A damper is provided on the lower surface of the top plate, and the lower end of the damper is connected to a support plate. Side plates are provided at both ends of the support plate for horizontal movement. The side plates are used to support the side walls. The side walls are connected to the moving parts of the damper through reinforcing rods. The two ends of the reinforcing rods are respectively hinged to the moving parts or the side plates. The two reinforcing rods are arranged in an eight-shaped shape. A plurality of support columns are provided at the lower part of the support plate, and a base is provided at the lower end of the support column.

[0005] The above-mentioned existing technology has limitations in actual use. It does not have side supports and cannot effectively protect the two sides of the exploration cave. When a geological collapse occurs, the rocks on both sides hit the support columns, causing damage to the support columns, resulting in an inability to provide stable support. At the same time, the collapsed rocks can easily cause personal injury to the explorers under the anti-collapse device. Utility Model Content

[0035] Embodiment 1

[0036] AsFigures 1-6 As shown in:

[0037] A geological exploration anti-collapse support device, including a support frame. At the top of the support frame, a roof plate 21 for roof support is installed. The roof plate 21 is connected to the top of the support frame through a spring damper 14. On the side of the support frame, a side plate 22 for side wall support is installed. The bottom of the side plate 22 is hinged to the support frame.

[0038] The support frame includes a base plate 11 and a bottom plate 12. Between the base plate 11 and the bottom plate 12, a plurality of support columns 13 are installed. The roof plate 21 is connected to the base plate 11 through a spring damper 14. The spring damper 14 provides resistance to movement and dissipates the kinetic energy of the large up and down shaking of the roof plate 21 after being stressed.

[0039] An expansion cylinder can be installed inside the support column 13 to adjust the height of the support column 13, thereby facilitating the application of this device to mine shafts, mine pits or tunnels with different height dimensions.

[0040] As Figure 2 shown, symmetric rotation holes 15 are opened on the base plate 11. Inside the rotation holes 15, a rotating shaft 33 is installed. Outside the rotating shaft 33, a linkage rod 3 is rotatably installed. At both ends of the linkage rod 3, a first roller 31 and a second roller 32 are respectively rotatably installed. The first roller 31 is slidably connected to the bottom surface of the roof plate 21, and the second roller 32 is slidably connected to the inner side surface of the side plate 22.

[0041] At the hinge joint of the linkage rod 3 and the rotating shaft 33, a torsion spring 34 is provided. Under the action of the torsion spring 34, it is ensured that the first roller 31 and the second roller 32 at both ends of the linkage rod 3 are respectively always slidably connected to the bottom surface of the roof plate 21 and the inner side surface of the side plate 22.

[0042] On the inner side wall of the side plate 22, a guide groove that cooperates with the second roller 32 and is slidably connected is opened.

[0043] Between the two first rollers 31, a block 7 fixedly installed on the bottom surface of the roof plate 21 is provided. An opening is opened on the block 7. The setting of the opening prevents the linkage rod 3 from being blocked by the block 7 during movement and thus restricts the movement of the linkage rod 3, ensuring the linkage effect between the roof plate 21 and the side plate 22.

[0044] As Figure 2 and Figure 3As shown in the figure, when the device is in use, the top plate 21 located at the top receives the pressure of the collapsed stones. Taking the left linkage rod 3 as an example, the top plate 21 moves downward. The first roller 31 of the left linkage rod 3 slides outward on the bottom surface of the top plate 21, and the linkage rod 3 rotates clockwise. The second roller 32 rotates accordingly. The second roller 32 is always slidably connected to the inner side surface of the side plate 22. The second roller 32 slides in the guiding groove of the side plate 22. Since the bottom of the side plate 22 is hinged, the side plate 22 starts to rotate counterclockwise under the action of the linkage rod 3 until the two side plates 22 extend outward and become inclined. The outer side of the inclined side plate 22 supports the side wall of the mine tunnel. The inner side surface of the side plate 22 buffers and guides the small stones sliding down from the top plate 21, preventing the side part sliders from collapsing and falling into the device interior and damaging the support column 13, and making them slide to the bottom of the side plate 22 to converge, preventing personal injury to the exploration personnel evacuating inside the device.

[0045] As Figures 4-6 shown, a telescopic movable seat 4 is provided on the side of the bottom plate 12. A scissor-type telescopic frame is installed between the movable seat 4 and the side of the bottom plate 12. The bottom of the side plate 22 is hinged to the movable seat 4.

[0046] A placement bin 41 is arranged inside the bottom plate 12. A through groove 42 is opened on the side wall of the placement bin 41. The scissor-type telescopic frame is installed inside the placement bin 41 and is connected to the movable seat 4 through the through groove 42.

[0047] The scissor-type telescopic frame includes a first hinge rod 51 and a second hinge rod 52 that are hinged in a scissor shape. One end of the first hinge rod 51 is hinged and installed on a fixed sleeve 53. The other end of the first hinge rod 51 is slidably connected to the movable seat 4 through a pulley 59. The pulley 59 moves in a chute opened on the movable seat 4. The chute plays a guiding and limiting role. One end of the second hinge rod 52 is hinged and installed on a movable sleeve 54. The other end of the second hinge rod 52 is hinged to the movable seat 4.

[0048] A guiding rod 55 is rotatably installed inside the placement bin 41. The fixed sleeve 53 and the movable sleeve 54 are installed on the guiding rod 55. The fixed sleeve 53 is rotatably connected to the guiding rod 55 and has a relatively fixed position. The guiding rod 55 is provided with an external thread 56. The movable sleeve 54 is helically connected to the external thread 56. The movable sleeve 54 moves axially on the external thread 56.

[0049] One end of the guiding rod 55 is connected to a driving motor 57 installed on the inner wall of the placement bin 41. The other end of the guiding rod 55 is connected to a rotating seat 58.

[0050] As Figure 6As shown in the figure, when the scissor expansion frame is in the storage state, it can be stored in the placement bin 41 and the through groove 42, so that the movable seat 4 contacts the side of the bottom plate 12, avoiding the situation that small stones or sundries fall on the scissor expansion frame during storage and enter the placement bin 41, which affects the secondary extension, and improving the connection stability and use safety.

[0051] The structure of the present utility model is simple. By providing the side plates 22 for side wall support, effective protection and support are provided for both sides of the device, avoiding the situation that the stones on both sides impact on the support columns 13 when geological collapse occurs, causing damage to the support columns 13 and resulting in the inability to stably support; preventing the situation that the collapsed stones cause personal injury to the exploration personnel under the anti-collapse device, and improving the protection ability and support strength.

[0052] Embodiment 2

[0053] As Figure 7 shown, in this embodiment, the articulated connecting rod 61 is installed between the base plate 11 and the side plate 22. The articulated connecting rod 61 limits the position and the extension amount of the extended side plate 22, avoiding the situation that the rotation angle of the side plate 22 is too large; at the same time, during the movement of the device, the position of the side plate 22 is limited to avoid the side plate 22 from unfolding and affecting the device's entry into the mine tunnel or tunnel. In addition, other technical solutions are the same as those in Embodiment 1.

[0054] In addition to the above technical solution of setting the articulated connecting rod 61, the second roller 32 can also be installed in the guide groove of the side plate 22. The opening width of the guide groove is greater than the width of the linkage rod 3, and the opening width of the guide groove is less than the width of the second roller 32. The second roller 32 is restricted in the guide groove, and the second roller 32 in this solution also has a limiting effect on the extension of the side plate 22.

[0055] Embodiment 3

[0056] As Figure 8 shown, in this embodiment, a protective tarpaulin 62 is installed between the base plate 11 and the side plate 22. The length of the protective tarpaulin 62 is the distance between the top of the side plate 22 and the side edge of the top plate 21 after the side plate 22 is unfolded.

[0057] The protective tarpaulin 62 is made of polyester weaving or polyethylene plastic material. In addition, other technical solutions are the same as those in Embodiment 1.

[0058] The setting of the protective tarpaulin 62 can prevent the stones that collapse from the top or side from falling into the device, causing the accumulation of stones or other sundries and affecting the retraction of the side plate 22; prevent small stones or sundries from falling onto the scissor expansion frame and entering the placement bin 41, which may affect the secondary expansion of the scissor expansion frame, and improve the connection stability and use safety; avoid the side slider from collapsing and falling into the device, damaging the support column 13, causing it to slide to the bottom of the side plate 22 and converge, and preventing personal injury to the exploration personnel evacuating inside the device.

[0059] Embodiment 4

[0060] As Figure 9 shown, in this embodiment, a limiting support rod 63 is installed on the inner side wall of the side plate 22. A rubber pad 64 is provided at the top end of the limiting support rod 63. The rubber pad 64 contacts the side bottom surface of the top plate 21. Through the limiting support rod 63, the side plate 22 limits and supports the top plate 21, preventing the top plate 21 from moving further downward.

[0061] A groove for the limiting support rod 63 to rotate through is formed on the side of the base plate 11, avoiding the base plate 11 from affecting the rotation of the limiting support rod 63. In addition, other technical solutions are the same as those in Embodiment 1.

[0062] In this embodiment, the top plate 21, the linkage rod 3, the side plate 22 and the limiting support rod 63 achieve self-locking, avoiding further sliding of the top plate 21 and preventing excessive rotation of the side plate 22, realizing effective support for the top and side parts.

[0063] Embodiment 5

[0064] As Figure 10 shown, in this embodiment, a support rod 65 inclined downward is installed on the outside of the side plate 22. The bottom of the support rod 65 is connected with a support seat 66 through a universal joint. A plurality of anti-slip bumps are provided on the bottom surface of the support seat 66.

[0065] By setting the support rod 65 and the support seat 66, the side plate 22 realizes firm support for the bottom of the side wall of the mine tunnel. The setting of the universal joint effectively helps the side plate 22 to support different-shaped contact surfaces, with strong applicability and a wide range of applications. In addition, other technical solutions are the same as those in Embodiment 1.

[0066] Embodiment 6

[0067] As Figure 11 shown, in this embodiment, a support nail 67 inclined downward is installed on the outside of the side plate 22. During the rotation of the side plate 22, the support nail 67 is inserted into the ground or side wall of the mine tunnel, avoiding the device from sliding along the entry and exit direction of the mine tunnel when the mine tunnel collapses, and at the same time providing sufficient support for the side plate 22. In addition, other technical solutions are the same as those in Embodiment 1.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
