Description

A device for repositioning and reinforcing fractured rock masses in stone cultural relics Technical Field

[0001] This utility model relates to the field of rock mass restoration, and in particular to a device for repositioning and reinforcing fractured rock masses in stone cultural relics. Background Technology

[0002] With the continuous development of modern engineering construction, rock engineering has received increasing attention, and the failure of engineering rock masses has always been a research hotspot. Under load, rock will deform, and as the load increases, the amount of deformation also increases. When the load reaches a certain value, it will lead to rock fracture and failure. Stone cultural relics belong to historical and cultural heritage. For rock masses with structural stability problems, the reinforcement and repair measures taken must adhere to the principles of cultural relic protection and repair, such as "minimal intervention" and "not changing the original form," to avoid the reinforcement and repair measures affecting the external display of cultural relics.

[0003] Currently, traditional rock mass reinforcement measures, such as demolition and reconstruction, and anchor bolt reinforcement, involve excessive intervention, damaging the original structural form of stone cultural relics and affecting the inheritance of their historical, scientific, and cultural value. Therefore, this proposal suggests a device for repositioning and reinforcing fractured rock masses in stone cultural relics. Summary of the Invention

[0004] This utility model proposes a device for repositioning and reinforcing fractured rock masses in stone cultural relics, which solves the problem of excessive interference with the rock mass structure in existing rock mass repositioning and reinforcement devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for repositioning and reinforcing fractured rock masses in stone cultural relics includes:

[0007] A vertical support mechanism includes a mounting plate, multiple first jacks fixed to the top surface of the mounting plate, and multiple detachable support columns installed on the bottom surface of the mounting plate. One end of the mounting plate is provided with a mounting groove.

[0008] The side support mechanism includes a movable plate movably disposed in the mounting groove, a fixed plate fixed to the top surface of the movable plate, a second jack hinged to the outer wall of the fixed plate near the mounting plate, and a telescopic rod installed at the output end of the second jack. The movable plate is equipped with an adjustment component for driving it to move along the length direction of the mounting plate.

[0009] An angle adjustment mechanism includes a movable sleeve movably fitted around the periphery of a telescopic rod, a connector hinged to the bottom surface of the movable sleeve, and a telescopic support rod hinged to the top surface of a mounting plate, wherein the support rod and the connector are detachably connected.

[0010] The above technical solution not only facilitates the support of the bottom and sides of the damaged rock mass, reducing intervention and damage to the rock mass itself, effectively suppressing the deformation and instability trend of the fractured rock mass, and ensuring the permanent stability of cultural relics and buildings, but also makes it convenient to store and transport the entire device, making it convenient for users to use outdoors.

[0011] As a further improvement to the above solution, the bottom surface of the mounting plate is fixed with a plurality of fixing frames for connecting the support column. The inner ring of the fixing frame matches the outer circumference of the support column. The outer circumference of the fixing frame is threaded with fixing bolts, and one end of the fixing bolt extends to the inner side of the fixing frame and abuts against the outer wall of the support column.

[0012] The above technical solution allows for easy disassembly and replacement of the support column.

[0013] As a further improvement to the above solution, a threaded hole is provided on the side of the mounting groove opposite to the short side of the moving plate, which is arranged along the length of the mounting groove. The adjustment assembly includes an adjustment screw rotatably connected to the moving plate and a rotating wheel fixed to one end of the adjustment screw. One end of the adjustment screw extends into the threaded hole and is threadedly connected to it.

[0014] As a further improvement to the above solution, a locking bolt is threadedly connected to one side of the movable plate, one end of the locking bolt abuts against the outer periphery of the adjusting screw, and a handle is fixed to the outer periphery of one end of the locking bolt.

[0015] As a further improvement to the above solution, the telescopic rod includes a movable rod and a fixed tube movably sleeved outside one end of the movable rod. The other end of the fixed tube is fixedly connected to the output end of the second jack. An abutment plate is fixed to the other end of the movable rod. Multiple fixing holes are equally spaced on both sides of the outer periphery of the fixed tube and are arranged along its axial direction. At least two of the multiple fixing holes on both sides of the fixed tube are internally threaded with positioning bolts. Multiple connecting holes corresponding to the fixing holes are opened on both sides of the movable rod, and the connecting holes match the positioning bolts.

[0016] As a further improvement to the above solution, the connecting component includes a connecting post hinged to the bottom surface of the movable sleeve and a connecting sleeve rotatably connected to the outer periphery of one end of the connecting post. The inner ring of the connecting sleeve is threaded. The support rod includes a fixing screw hinged to the top surface of the mounting plate, a threaded sleeve threaded to the outer periphery of the other end of the fixing screw, and a connecting screw fixed to the other end of the threaded sleeve. The connecting screw matches the inner ring of the connecting sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By setting up a vertical support mechanism, an installation plate can be placed under the damaged rock mass. After it is fixed, the first jack is used to support it from the bottom of the rock mass, thereby providing vertical force for the rock mass to be reset. Moreover, the support columns can be easily disassembled, so the length of each support column can be replaced according to the support surface under the damaged rock mass, thus making it easy to ensure that the top surface of the installation plate is in a horizontal state.

[0019] 2. By setting up a side support mechanism and an angle adjustment mechanism, the side of the damaged rock mass can be supported by adjusting the length and tilt angle of the telescopic rod, thereby facilitating the repositioning of the rock mass by providing horizontal force.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example 1:

[0028] Referring to Figures 1-4, this embodiment of a stone cultural relic fracture rock mass repositioning and reinforcement device includes:

[0029] The vertical support mechanism includes a mounting plate 1, multiple first jacks 2 fixed to the top surface of the mounting plate 1, and multiple detachable support columns 18 mounted on the bottom surface of the mounting plate 1. One end of the mounting plate 1 has a mounting groove 22. Multiple fixing frames 23 for connecting the support columns 18 are fixed to the bottom surface of the mounting plate 1. The inner ring of the fixing frame 23 matches the outer circumference of the support column 18. Fixing bolts 24 are threaded onto the outer circumference of the fixing frame 23, and one end of the fixing bolt 24 extends to the inner side of the fixing frame 23 and abuts against the outer wall of the support column 18. The fixing bolts can be adjusted according to the specific usage environment. When replacing the support column 18 with one of different lengths, and placing the mounting plate 1 at the bottom of the damaged rock mass, select a support column 18 of appropriate length, insert it into the fixing frame 23 and tighten it with fixing bolts 24, so that the bottom of the support column 18 abuts against the bottom support surface of the damaged rock mass, and the top surface of the mounting plate 1 remains horizontal. Then, lift multiple first jacks 2 upwards. During this process, pads can also be fixed or placed on the top of the output end of the first jack 2, so that the first jack 2 can provide a larger area of ​​support after contacting the bottom of the damaged rock mass.

[0030] The side support mechanism includes a movable plate 3 movably disposed within the mounting groove 22, a fixed plate 6 fixed to the top surface of the movable plate 3, a second jack 7 hinged to the outer wall of the fixed plate 6 near the mounting plate 1, and a telescopic rod installed at the output end of the second jack 7. An adjustment assembly for driving the movable plate 3 to move along the length of the mounting plate 1 is installed on the movable plate 3. A threaded hole 20 is provided along the length of the mounting groove 22 on the side opposite to the short side of the movable plate 3. The adjustment assembly includes an adjusting screw 21 rotatably connected to the movable plate 3 and a rotating wheel 25 fixed to one end of the adjusting screw 21. One end of the adjusting screw 21 extends into the threaded hole 20 and is threadedly connected thereto. The position of the mounting plate 1... After being fixed, the first jack 2 provides vertical support to the rock mass, and then the side support mechanism provides horizontal support to the rock mass. When adjusting the side support mechanism, first rotate the wheel 25 to drive the moving plate 3 to move. After rotating the wheel 25 clockwise, it drives the adjusting screw 21 to rotate in the forward direction, thereby driving the moving plate 3 to move away from the mounting plate 1 until the telescopic rod moves to a position away from directly below the rock mass. Then, the telescopic rod is used to support the side of the rock mass, and the second jack 7 applies pressure to the telescopic rod to support the side of the rock mass, so that there is a horizontal force supporting the damaged rock mass, which can effectively improve the stability of the rock mass during repair.

[0031] The telescopic rod includes a movable rod 17 and a fixed tube 16 movably sleeved outside one end of the movable rod 17. The other end of the fixed tube 16 is fixedly connected to the output end of the second jack 7. A stop plate 19 is fixed to the other end of the movable rod 17. Multiple fixing holes 14 are equally spaced on both sides of the outer periphery of the fixed tube 16 and are arranged along its axial direction. At least two of the fixing holes 14 on both sides of the fixed tube 16 are internally threaded with positioning bolts 15. Multiple connecting holes corresponding to the fixing holes 14 are opened on both sides of the movable rod 17, and the connecting holes fit with the positioning bolts 15. When using the telescopic rod to support the side of the damaged rock mass, the extension can be adjusted. The length of the telescopic rod is adjusted to ensure that the abutment plate 19 is pressed firmly against the surface of the damaged rock mass. During adjustment, first remove the positioning bolt 15 from the connecting hole, and then move the movable rod 17. Pulling the movable rod 17 outward will increase the length of the telescopic rod, and retracting the movable rod 17 into the fixed tube 16 will decrease the length of the telescopic rod. After adjustment, tighten the positioning bolt 15 into the connecting hole opposite it to lock the movable rod 17. Then, activate the second jack 7 to extend, thereby moving the telescopic rod until the abutment plate 19 is pressed firmly against the outer wall of the damaged rock mass. At the same time, the length of the telescopic rod can be adjusted, which also makes it convenient to shorten and lay the telescopic rod down when storing it, making it easy to carry and transport.

[0032] A locking bolt 4 is threadedly connected to one side of the movable plate 3. One end of the locking bolt 4 abuts against the outer circumference of the adjusting screw 21. A handle 5 is fixed to the outer circumference of one end of the locking bolt 4. After the position of the movable plate 3 is adjusted, the locking bolt 4 is tightened to prevent it from moving. This causes one end of the locking bolt 4 to abut against the outer circumference of the adjusting screw 21, thereby using the friction between the two to lock the adjusting screw 21, preventing it from rotating easily, and ultimately achieving the purpose of locking the movable plate 3.

[0033] After using vertical support mechanisms to support the bottom of the damaged rock mass and side support mechanisms to support the sides of the rock mass, high-strength mortar is used to fill the cracks at the contact point between the two fractured rock masses to reinforce the rock mass. The high-strength mortar used is CGM-6 high-strength non-shrink grout.

[0034] Example 2:

[0035] Referring to Figures 1-3, this embodiment, based on Embodiment 1, further improves upon the following: The angle adjustment mechanism includes a movable sleeve 11 movably fitted around the outer periphery of the telescopic rod, a connector hinged to the bottom surface of the movable sleeve 11, and a telescopic support rod hinged to the top surface of the mounting plate 1. The support rod and the connector are detachably connected. The connector includes a connecting post 13 hinged to the bottom surface of the movable sleeve 11 and a connecting sleeve 12 rotatably connected to the outer periphery of one end of the connecting post 13. The inner ring of the connecting sleeve 12 is threaded. The support rod includes a fixing screw 10 hinged to the top surface of the mounting plate 1, a threaded sleeve 8 threadedly fitted to the outer periphery of the other end of the fixing screw 10, and a connecting screw 9 fixed to the other end of the threaded sleeve 8. The connecting screw 9 engages with the inner ring of the connecting sleeve 12. When the telescopic rod supports the side of the damaged rock mass, it needs to... To raise the telescopic rod to a certain angle, the angle between the telescopic rod and the mounting plate changes depending on the height of the rock mass. After adjusting the length and tilt angle of the telescopic rod, the length of the support rod is adjusted so that the connecting screw 9 can be screwed into the inner side of the connecting sleeve 12. This allows the support rod to support the telescopic rod and ensure its stability during the process of pressing against the damaged rock mass. When adjusting the length of the support rod, rotating the threaded sleeve 8 clockwise will increase the length of the support rod, while rotating it counterclockwise will decrease the length. After adjusting the length of the support rod, the connecting sleeve 12 is connected to the connecting screw 9, and the connecting sleeve 12 is rotated clockwise to thread it onto the outside of the connecting screw 9, thus completing the support of the telescopic rod.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
