Description

Technical Field

[0001] This utility model relates to the field of rock fissure-making devices, specifically a rock expansion and fissure-making device. Background Technology

[0002] Rock expansion and cracking refers to the process of creating new cracks or widening existing cracks in a rock structure through specific technical means. This technology has important applications in fields such as geological exploration and water conservancy engineering. It can improve the permeability of rocks, reduce the strength of rocks, and provide convenient conditions for subsequent engineering operations.

[0003] However, in some mountainous areas, due to complex terrain and construction difficulties, power facilities have not been able to achieve full coverage. When carrying out rock expansion and crack making operations in these areas, electric machinery cannot be relied upon, and manual labor is the only option. Construction workers usually use a combination of stone chisels and impact hammers, and gradually chisel out the required cracks on the rock surface by repeatedly hammering the stone chisels manually.

[0004] In actual operation, personnel need to hold the stone chisel with their hands to ensure that the chisel can accurately form a hole on the rock surface when it is hit by the impact hammer. However, this operation method has a great safety risk. When using the impact hammer to hit the stone chisel, it is difficult to control the operating force and angle precisely. The impact hammer can easily hit the operator's hand accidentally, resulting in serious personal injury and greatly threatening the life safety and health of the construction workers. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a rock expansion and crack-making device to solve the technical problem that the impact hammer can easily hit the operator's hand accidentally during the process of using the impact hammer to strike the rock chisel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rock expansion and fracture creation device, including a rock chisel, the outer wall of which is provided with three sets of leg frames, the bottom of which is connected to a support leg, the rock chisel having an inner cavity, a chisel being movably disposed inside the inner cavity, a force-bearing block being fixed to the top of the chisel, and a limiting ring being fitted on the outer wall of the chisel.

[0007] By adopting the above technical solution, the problem of the impact hammer easily hitting the operator's hand during the process of using the impact hammer to strike the rock chisel is solved. First, the support legs connected to the bottom of the rock chisel are adjusted according to the terrain of the excavation area so that the rock chisel is placed horizontally. Then, the limiting ring and the chisel are inserted into the inner cavity of the rock chisel. The operator holds the bent area of ​​a set of legs. By increasing the distance between the hand support position and the chisel, the impact hammer is less likely to hit the operator's hand when striking the force block at the top of the chisel, thereby increasing the safety of the operator when excavating rocks.

[0008] The present invention is further configured such that the inside of the leg frame is provided with a cavity, and the leg frame is fixed to the outer wall of the stone chisel by welding.

[0009] Preferably, the leg frame has a cavity inside, which can reduce the overall weight of the device, thereby reducing the physical effort required for personnel to carry the stone chisel.

[0010] The present invention is further configured such that a connecting column is installed on the top of the support leg, the diameter of the connecting column is equal to the diameter of the cavity, and the connecting column is connected to the leg frame by a thread.

[0011] Preferably, the support leg is connected to the bottom of the leg frame via a connecting column, and the connecting column is installed at the bottom of the leg frame via a threaded connection, allowing the operator to rotate and adjust the height of the support leg.

[0012] The present invention is further provided with a foot pad at the bottom of the support leg, the foot pad being made of polyurethane material.

[0013] Preferably, the foot pads made of polyurethane material can increase the friction between the support leg and the rock, so that the chisel does not easily slip when it hits the rock face.

[0014] The present invention is further configured such that a hexagonal hole is provided inside the limiting ring, and the diameter of the hexagonal hole is larger than the diameter of the chisel.

[0015] Preferably, the chisel strikes the rock face downwards, and slides in the hexagonal hole inside the limiting ring, so that the chisel's movement direction is limited and controlled by the limiting ring, preventing the chisel from shaking during the impact on the rock.

[0016] The present invention is further configured such that the inner wall of the hexagonal hole is provided with six sets of sliding grooves, and the outer wall of the chisel is fixed with six sets of limiting blocks.

[0017] Preferably, when the operator completes the rock-opening operation, the operator can lift the chisel upwards so that the chisel can pass through the limiting block and remove the limiting ring from inside the rock-cutting tool.

[0018] The present invention is further configured such that the diameter of the inner cavity is equal to the diameter of the limiting ring, and the inner wall of the bottom of the stone chisel is smaller than the diameter of the inner cavity.

[0019] Preferably, when the limiting ring is placed in the inner cavity of the stone chisel, the bottom wall of the inner wall of the stone chisel supports the limiting ring, so that when the person lifts the stone chisel, the chisel and the limiting ring slide down through the inner cavity of the stone chisel.

[0020] The present invention is further configured such that a hook is fixed to the outer wall of the stone chisel, and the hook is fixed to the outer wall of the stone chisel by welding.

[0021] As a preferred option, since it is not easy to transport large quantities of objects on mountain roads, a set of hooks is welded to the outer wall of the stone chisel. Personnel can hook the hooks onto the hooks, making it convenient for them to hang the stone chisel on their waist.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem that the impact hammer can easily hit the operator's hand when using a rock chisel by setting up a rock chisel, legs, inner cavity, limiting ring, and chisel. First, the support legs connected to the bottom of the rock chisel are adjusted according to the terrain of the excavation area so that the rock chisel is placed horizontally. Then, the limiting ring and chisel are inserted into the inner cavity of the rock chisel. The operator holds the bent area of ​​a set of legs. By increasing the distance between the hand support position and the chisel, the impact hammer is less likely to hit the operator's hand when striking the force block at the top of the chisel, thereby increasing the safety of the operator when excavating rocks.

[0024] 2. This utility model incorporates a leg support, a protective sleeve, and an anti-slip sleeve. The bending area of ​​the leg support is equipped with a protective sleeve made of neoprene rubber. When the impact hammer strikes the chisel, the chisel transmits the vibration to the stone chisel through the limiting ring, causing the stone chisel to vibrate at a high frequency. The neoprene rubber protective sleeve on the outer wall of the leg support absorbs and buffers the vibration of the stone chisel, thereby reducing the injury to the operator's hands from the vibration. Furthermore, the outer wall of the protective sleeve is equipped with a nylon anti-slip sleeve, which has good breathability, making it less likely for the operator to slip due to sweaty hands during prolonged use.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Please see Figure 1 — Figure 6 The device includes a rock chisel 1, with three sets of legs 2 on its outer wall. Support legs 3 are connected to the bottom of the legs 2. The rock chisel 1 has an inner cavity 102, and a chisel 5 is movably installed inside the inner cavity 102. A force-bearing block 501 is fixed to the top of the chisel 5. A limiting ring 6 is fitted on the outer wall of the chisel 5. This device solves the problem that the impact hammer can easily hit the operator's hand when striking the rock with an impact hammer. First, the support legs 3 connected to the bottom of the rock chisel 1 are adjusted according to the terrain of the excavation area so that the rock chisel 1 is placed horizontally. Then, the limiting ring 6 and the chisel 5 are inserted into the inner cavity 102 inside the rock chisel 1. The operator holds the bent area of ​​one set of legs 2. By increasing the distance between the hand support position and the chisel 5, the impact hammer is less likely to hit the operator's hand when striking the force-bearing block at the top of the chisel 5, thereby increasing the safety of the operator when excavating rocks.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 3The leg frame 2 has a cavity 201 inside. The leg frame 2 is fixed to the outer wall of the stone chisel 1 by welding. The cavity 201 inside the leg frame 2 can reduce the overall weight of the device, thereby reducing the physical effort required for personnel to move the stone chisel 1.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 A connecting column 301 is installed on the top of the support leg 3. The diameter of the connecting column 301 is equal to the diameter of the cavity 201. The connecting column 301 is connected to the leg frame 2 by a thread. The support leg 3 is connected to the bottom of the leg frame 2 by the connecting column 301. The connecting column 301 is installed at the bottom of the leg frame 2 by a threaded connection, so that the personnel can rotate the support leg 3 to adjust its height.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The bottom of the support leg 3 is equipped with a foot pad 302. The foot pad 302 is made of polyurethane material. The polyurethane material foot pad 302 can increase the friction between the support leg 3 and the rock, so that the chisel 5 impacts the rock wall and the stone chisel 1 is less likely to slip.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The limiting ring 6 has a hexagonal hole 601 inside, and the diameter of the hexagonal hole 601 is larger than the diameter of the chisel 5. When the chisel 5 strikes the rock wall downwards, the chisel 5 slides in the hexagonal hole 601 inside the limiting ring 6, so that the rock chisel 1 controls the movement direction of the chisel 5 through the limiting ring 6, preventing the chisel 5 from shaking during the impact of the rock.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 6 The inner wall of the hexagonal hole 601 is provided with six sets of sliding grooves 601, and the outer wall of the chisel 5 is fixed with six sets of limiting blocks 502. When the operator completes the rock cracking operation, the operator can lift the chisel 5 upwards, so that the chisel 5 can take out the limiting ring 6 through the inside of the rock chisel 1 through the limiting block 502.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 and Figure 5 The diameter of the inner cavity 102 is equal to the diameter of the limiting ring 6. The inner wall of the bottom of the stone chisel 1 is smaller than the diameter of the inner cavity 102. When the limiting ring 6 is placed in the inner cavity 102 inside the stone chisel 1, the wall at the bottom of the inner wall of the stone chisel 1 supports the limiting ring 6, so that when the person lifts the stone chisel 1, the chisel 5 and the limiting ring 6 slide down through the inner cavity 102 inside the stone chisel 1.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 2The outer wall of the stone chisel 1 is fixed with a hook 101, and the hook 101 is fixed to the outer wall of the stone chisel 1 by welding. Since it is not easy to transport a large number of objects on mountain roads, a set of hooks 101 is welded to the outer wall of the stone chisel 1. People can hook the hooks 101 with hooks, which makes it convenient for people to hook the stone chisel 1 to their waist.

[0043] In practical operation, this invention works as follows: First, the support legs 3 connected to the bottom of the stone chisel 1 are adjusted according to the terrain of the excavation area. The three sets of support legs 3 are rotated to make the stone chisel 1 horizontal. Then, the limiting ring 6 and the chisel 5 are inserted into the inner cavity 102 of the stone chisel 1. The height of the three sets of support legs 3 is adjusted so that when the limiting ring 6 is placed in the stone chisel 1, the sharp bottom end of the chisel 5 contacts the surface of the rock to be excavated. The limiting block 502 on the inner wall of the chisel 5 is located at the top of the groove 602 on the inner wall of the limiting ring 6. Then, the operator holds the bending area of ​​one set of legs 2. Finally, the impact hammer is used to strike the force block 501 at the top of the chisel 5, so that the chisel 5 impacts and opens the rock wall. When the chisel 5 impacts downward, the stone chisel 1 controls the movement direction of the chisel 5 through the limiting ring 6 that is movably fitted on the outer wall of the chisel 5, preventing the chisel 5 from tilting during the impact hammer's strike.
