Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a rock mass anchoring device. Background Art

[0002] The structural methods of rock and soil anchoring mainly include friction or adhesive anchoring and end-bearing anchoring. Among them, end-bearing anchoring is to bury the anchor rod in the rock and soil layer, relying on the supporting force of the rock and soil layer on the anchor rod as the tensile force. After the end bearing is anchored to the rock and soil, anchors and pedestals are used to support the outside of the wall.

[0003] For example, a special anchor for four cables of glass fiber reinforcement disclosed in the patent document with publication number CN209568431U is made by welding a lower I-beam to the steel bars implanted in the pile, and an upper I-beam is placed above the lower I-beam. The two groups of I-beams are connected and fixed by the long right-angled sides of a rectangular welded triangular steel plate. A pedestal for a push jack is welded on the hypotenuse of the rectangular welded triangular steel plate. Four anchor insertion holes with apertures corresponding to the diameters of the anchor rods are provided on the hypotenuse of the rectangular welded triangular steel plate. The front end of the jack is locked and reinforced by an anchor plate and a special nut, thereby realizing stable anchoring of a single-sided pile foundation and soil.

[0004] During the anchoring support process, due to the different inclination angles of the rock mass at different locations, in order to facilitate full anchoring with the rock and soil support, it is necessary to stack triangular steel plates of different thicknesses and other pads between the pedestal and the rock mass according to the inclination angle of the rock anchoring point for auxiliary support. This process is cumbersome and requires repeated adjustments to the size of the pads, which affects the efficiency of rock and soil anchoring. Utility Model Content

[0030] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0031] An embodiment of the utility model provides a rock anchoring device. During the process of anchoring the rock mass 10a, the anchoring device adjusts the pedestal to be parallel to the rock mass 10a, thereby facilitating the fixation of the pedestal and the rock mass 10a and improving the anchoring efficiency of the rock mass 10a, thereby solving the technical problem in the prior art of requiring a gasket to be placed between the pedestal and the rock mass 10a, resulting in low anchoring efficiency of the rock mass 10a.

[0032] like Figure 1-3 As shown, the rock anchoring device provided by the utility model includes an anchor 10, a supply and rotation module 20 and a pedestal 30, wherein the anchor 10 is used to connect the rock 10a; the supply and rotation module 20 is connected to the anchor 10 and is perpendicular to the axial direction of the anchor 10; the pedestal 30 is rotatably connected to the supply and rotation module 20, and can adjust the angle with the rock 10a by rotating around the supply and rotation module 20.

[0033] Specifically, the rock anchoring device is provided with an anchor 10, a supply and rotation module 20 and a pedestal 30. When performing rock and soil anchoring work, the anchoring device is inserted into the rock 10a through the anchor 10, the supply and rotation module 20 is connected to the anchor 10 and is perpendicular to the axial direction of the anchor 10, and the pedestal 30 is rotatably connected to the supply and rotation module 20. The pedestal 30 rotates around the supply and rotation module 20 to adjust the angle. After the connection between the anchor 10 and the wall is completed, the pedestal 30 is rotated to adjust the angle. , the angle between the pedestal 30 and the rock mass 10a is adjusted until the pedestal 30 is parallel to the rock mass 10a, and then the pedestal 30 is fixed to the rock mass 10a, so that the rock mass 10a can be anchored. Through the above setting of the anchoring device, when the rock mass 10a is anchored, it is not necessary to add a gasket between the pedestal 30 and the rock mass 10a to achieve the fixation of the pedestal 30 and the wall, thereby improving the anchoring efficiency of the rock mass 10a and providing convenience for the anchoring of the rock mass 10a.

[0034] In this embodiment, the rock mass 10a is a rock and soil wall with high hardness.

[0035] It can be understood that the anchor 10 can be an anchor rod or a combination of an anchor rod and an anchor.

[0036] It can be understood that the rotation module 20 can be any rotation member that can provide rotation for the pedestal 30, such as a rotation shaft mounted on the pedestal 30, or a rotation sleeve inserted into the rotating part of the pedestal 30. The rotation module 20 can be connected to the anchor 10 in a fixed connection, a rotation connection, etc.

[0037] It can be understood that the pedestal 30 can be any structural member that can be rotatably connected to the supply module 20 and fixed to the rock mass 10a. The rotation direction and rotation angle of the pedestal 30 can be adaptively set according to the inclination direction and inclination angle of the rock mass 10a. If the rock mass 10a is inclined in the vertical direction, the pedestal 30 should be kept rotating in the vertical direction during the anchoring process. If the rock mass 10a is inclined in the horizontal direction, the pedestal 30 should be kept rotating in the horizontal direction during the anchoring process.

[0038] In some embodiments, Figure 2-3 As shown, the rotation supply module 20 includes a rotation supply bolt 21, which is threadedly connected to the anchor 10 and is perpendicular to the axial direction of the anchor 10. The pedestal 30 is rotatably connected to the rotation supply bolt 21 and can be locked by the rotation supply bolt 21. Specifically, the rotation supply bolt 21 provides rotation for the pedestal 30, and after the pedestal 30 completes the angle adjustment by rotation, the pedestal 30 can be locked by tightening it on the anchor 10, so that the pedestal 30 can be pre-tightened before the pedestal 30 is fixed to the rock mass 10a, so as to prevent the pedestal 30 from rotating during the process of fixing it to the rock mass 10a, thereby providing convenience for the anchoring work.

[0039] In some embodiments, Figure 2-3 As shown, there are two rotation supply bolts 21, which are arranged opposite to each other, and the pedestal 30 is an annular pedestal, which is enclosed by the anchor 10 and rotatably connected to the two rotation supply bolts 21. Specifically, by two sets of opposite rotation supply bolts 21, the pedestal 30 can be stably rotated relative to the anchor 10, and by providing the pedestal 30 with an annular structure, the pedestal 30 and the rock mass 10a can be fixed in the circumferential direction, thereby improving the stability of the connection between the pedestal 30 and the rock mass 10a.

[0040] In some embodiments, Figure 2-3 As shown, a rotating frame 31 is provided on one side of the pedestal 30 close to the anchor 10, the rotating frame 31 is sleeved on the rotation supply bolt 21 and is rotationally connected with the rotation supply bolt 21, and the rotating frame 31 is provided with a control cavity 311 for controlling the rotation supply bolt 21. Specifically, the rotating frame 31 can realize the pedestal 30 to stably rotate around the rotation supply bolt 21, and can also provide convenience for the control of the rotation supply bolt 21.

[0041] In this embodiment, Figure 2-3 As shown, the rotating frame 31 is a U-shaped frame.

[0042] In some embodiments, Figure 1-3As shown, the anchor 10 includes an anchor rod 11 and an anchor 12. The anchor 12 is sleeved on the anchor rod 11 and can move axially along the anchor rod 11. The supply and rotation module 20 is connected to the anchor 12. A plurality of support members 32 are arranged at intervals in the circumferential direction of the base 30. Each support member 32 can be supported on the rock mass 10a by the movement of the anchor 12 toward the rock mass 10a.

[0043] Specifically, the anchor rod 11 can be connected to the rock mass 10a by passing through the rock mass 10a. Through the arrangement of a plurality of support members 32 and an axially movable anchor 12, when anchoring the rock mass 10a, it is only necessary to control the anchor 12 to gradually move toward the direction of the rock mass 10a. One of the support members 32 first contacts the rock mass 10a, and then the rear seat 30 drives the pedestal 30 to rotate under the reverse force of the rock mass 10a acting on the support member 32, so that the other support members 32 are in contact with the rock mass 10a, and the angle of the pedestal 30 can be adjusted. Therefore, through the cooperation of the anchor 12 and the support members 32, the angle adjustment of the pedestal 30 can be facilitated, thereby improving the anchoring efficiency of the rock mass 10a. After the angle adjustment of the pedestal 30 is completed, the pedestal 30 can be locked by the rotation bolt 21.

[0044] It can be understood that the anchor 12 can be connected to the anchor rod 11 by sliding connection with the anchor rod 11 and achieve axial movement along the anchor rod 11.

[0045] In some embodiments, the anchor 12 is threadedly connected to the anchor rod 11. Specifically, through this arrangement, the anchor 12 can be controlled to move axially along the anchor rod 11 by simply twisting the anchor 12, thereby driving the pedestal 30. Through the threaded connection between the anchor 12 and the anchor rod 11, the anchor 12 can be locked while moving axially along the anchor rod 11.

[0046] It can be understood that the support member 32 can be any structure that can contact and be fixed to the rock mass 10a, and the support member 32 can be connected to the base 30 in a fixed connection or a sliding connection.

[0047] In some embodiments, Figure 1-3 As shown, the support member 32 includes a connecting frame 321 and a supporting plate 322, the connecting frame 321 is connected to the pedestal 30, the supporting plate 322 is fixed to the connecting frame 321, and can be fitted with the rock mass 10a by moving the anchor 12 toward the rock mass 10a. Specifically, the support member 32 is stably connected to the pedestal 30 through the connecting frame 321, and the pedestal 30 and the rock mass 10a are stabilized by the fitting of the supporting plate 322 and the rock mass 10a, thereby ensuring the anchoring quality of the rock mass 10a.

[0048] In this embodiment, Figure 2-3As shown, the support member 32 is provided with anchor holes for anchoring nails to penetrate, and the support member 32 can be fixed to the rock mass 10a by the anchoring nails to achieve anchoring of the rock mass 10a.

[0049] In some embodiments, Figure 1-3 As shown, the rock anchoring device further includes a plurality of adjustment modules 40, each support member 32 is connected to the pedestal 30 in a radially sliding manner, and each adjustment module 40 is separately connected to each support member 32, and is used to drive each support member 32 to slide. Specifically, after the angle of the pedestal 30 is adjusted, the slide of each support member 32 can be controlled by the adjustment module 40 according to the actual anchoring requirements of the rock mass 10a, so as to select a suitable fixed position to fix the support member 32 to the rock mass 10a, so as to ensure that each support member 32 can be well matched with the rock mass 10a, and the stable anchoring of the rock mass 10a is achieved.

[0050] It is understandable that the adjustment module 40 can be a screw, a sliding rod or other components that is slidably connected to the base 30 and fixed to the support member 32 .

[0051] In some embodiments, Figure 2 As shown, the adjustment module 40 includes a guide rod 41 and an adjustment bolt 42. The guide rod 41 is fixed to the pedestal 30 and extends in the radial direction of the pedestal 30. The adjustment bolt 42 is rotatably connected to the pedestal 30 and arranged in parallel with the guide rod 41. The support member 32 is sleeved on the guide rod 41 and the adjustment bolt 42 and is threadedly connected with the adjustment bolt 42. Specifically, when the position of the support member 32 needs to be adjusted, the support member 32 can be driven to slide along the guide rod 41 by controlling the adjustment bolt 42 to adjust the position of the support member 32. Through the arrangement of the guide rod 41 and the adjustment bolt 42, the radial adjustment of the support member 32 can be facilitated, and the adjusted support member 32 can be locked by the threaded connection of the adjustment bolt 42, which provides convenience for the fixation of the support member 32 to the rock mass 10a.

[0052] In this embodiment, there are two guide rods 41 , and the two guide rods 41 are respectively located on both sides of the adjusting bolt 42 .

[0053] In some embodiments, Figure 2 As shown, a plurality of spaced supply slide grooves 33 are provided in the circumferential direction of the pedestal 30, and the supply slide grooves 33 extend in the radial direction of the pedestal 30, and the guide rod 41 and the adjusting bolt 42 are both provided in the supply slide grooves 33. Specifically, the supply slide grooves 33 can be used for installing the guide rod 41 and the adjusting bolt 42, and provide a limit for the support member 32, thereby improving the stability of the support member 32 sliding along the radial direction of the pedestal 30.

[0054] The specific working principle of the rock anchoring device provided by the embodiment of the utility model is as follows: when performing the anchoring work of the rock mass 10a, the anchor rod 11 is first inserted and penetrated into the rock mass 10a, and then the anchor 12 is threadedly connected to the anchor rod 11, and by rotating the anchor 12, the anchor 12 drives the pedestal 30 to move toward the rock mass 10a. During the movement of the pedestal 30 toward the rock mass 10a, the rock mass 10a will drive the pedestal 30 to rotate through the support member 32, so that the pedestal 30 is parallel to the rock mass 10a, and at the same time, the support plate 322 of each support member 32 is made to fit with the rock mass 10a, and then the pedestal 30 is locked by tightening the rotation bolt 21. After the locking of the pedestal 30 is completed, the sliding of each support member 32 is controlled by the adjusting bolt 42, so that the support member 32 is moved to the optimal fixed position, and then the support member 32 is fixed to the rock mass 10a through the support plate 322, so as to finally achieve efficient anchoring of the rock mass 10a.
