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.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Example 1

[0024] A protective cover device for rock cutting machines, such as Figure 1-5 As shown, it is mainly composed of protective body 1, fixed shell 2, elastic support mechanism 3, cutting machine assembly 4, telescopic rod 5, rotating disk 7, fixed ring 13, opening and closing cover 10 and other components;

[0025] The protective body 1 is made of high-strength, impact-resistant engineering plastic material and manufactured by injection molding process. It has good mechanical strength and protective performance. The cutting machine component 4 is installed inside to provide a working space for cutting operations. The bottom outer side of the protective body 1 is elastically connected to the fixed shell 2. The fixed shell 2 is made of stainless steel and manufactured by welding process. It has high strength and stability. Elastic support mechanisms 3 are set at the four corners between the protective body 1 and the fixed shell 2 to play a role in buffering and stabilizing.

[0026] The elastic support mechanism 3 includes a first support plate 301, a second support plate 302, a guide rod 303, a spring 304, and a rubber protective cover 305. The first support plate 301 is fixedly connected to the protective body 1 by bolts, and the second support plate 302 is also fixedly connected to the fixed shell 2 by bolts. The guide rod 303 is fixed to the top of the second support plate 302 and passes through the first support plate 301 to ensure that the protective body 1 maintains stable guidance when moving up and down. The spring 304 is sleeved on the outside of the guide rod 303, and its two ends are fixed to the first support plate 301 and the second support plate 302 respectively to provide elastic support force. The rubber protective cover 305 is sleeved on the outside of the guide rod 303 and the spring 304 to prevent dust and debris from entering and protect the normal operation of the elastic support mechanism.

[0027] The telescopic pole 5 is an electric or hydraulic telescopic pole. A connector 6 is fixed to the top of one side of the protective body 1. The connector 6 is connected to external equipment such as power supply and control device to provide power and control signals to the telescopic pole 5. A fixing plate 8 is fixed to the output end of the telescopic pole 5. The fixing plate 8 is welded to the rotating disk 7 to realize the lifting and lowering control of the telescopic pole 5 on the rotating disk 7.

[0028] The rotating disk 7 is made of high-strength aluminum alloy and is manufactured by machining process. The outer side of the rotating disk 7 is fixed to the sliding ring 12 extending into the inside of the fixed ring 13, which cooperates with the sliding groove 14 inside the fixed ring 13 to realize the flexible rotation of the rotating disk 7 relative to the fixed ring 13. The top two sides of the rotating disk 7 are fixed with handles 15, and the outer side of the handles 15 is covered with rubber rings to increase friction and make it convenient for operators to rotate the rotating disk 7.

[0029] The opening and closing cover 10 and the protective body 1 are rotatably connected by a hinge 11. The opening and closing cover 10 is made of transparent polycarbonate material, which not only makes it convenient for operators to observe the cutting process, but also effectively blocks flying fragments and dust. The opening and closing cover 10 has a handle 17 inside, which makes it convenient for operators to open and close the opening and closing cover 10.

[0030] The top of the protective body 1 is equipped with a dust suction pipe 9. The dust suction pipe 9 is made of flexible rubber or metal corrugated pipe. One end is connected to the inside of the protective body 1, and the other end is connected to external air suction equipment such as vacuum cleaner or dust collector through a pipe to absorb the dust generated during the cutting process in time and improve the working environment.

[0031] The top of the protective body 1 is equipped with a control panel 16. The control panel 16 is a touch control panel that is electrically connected to the cutting machine assembly 4 and the telescopic rod 5. The operator can control the starting, stopping, speed adjustment and other functions of the cutting machine assembly 4, as well as the lifting and lowering of the telescopic rod 5 through the control panel 16, so as to achieve precise control of the cutting operation.

[0032] Equipment installation and commissioning

[0033] At the rock cutting site, use hoisting machinery to lift the rock cutting machine protective cover to the vicinity of the rock surface to be cut, fix the fixing ring 13 on a stable foundation, and ensure that the fixing ring 13 is secure. Connect the telescopic rod 5 to the external equipment through the connector 6, connect the power supply and control signal line, check whether the spring 304 of the elastic support mechanism 3 is normal and whether the guide rod 303 is smooth, open the opening and closing cover 10, check whether the saw blade of the cutting machine component 4 is securely installed and whether each component is normal, close the opening and closing cover 10, and debug the equipment through the control panel 16 to test the operation of the cutting machine component 4 and the lifting function of the telescopic rod 5 to ensure that the equipment is operating normally.

[0034] Cutting operation

[0035] After the equipment is debugged, start the cutting machine assembly 4. Adjust the saw blade speed to a suitable cutting speed through the control panel 16. Operate the control panel 16 to lower the telescopic rod 5, which in turn lowers the protective body 1 and the cutting machine assembly 4. During the descent, the spring 304 of the elastic support mechanism 3 gradually contracts to provide stable buffering force. After the saw blade of the cutting machine assembly 4 contacts the rock surface, continue to slowly lower the telescopic rod 5 so that the saw blade gradually cuts into the rock. During the cutting process, the operator can observe the cutting situation through the transparent opening and closing cover 10. Adjust the descent speed of the telescopic rod 5 and the saw blade speed through the control panel 16 as needed. At the same time, the dust suction pipe 9 absorbs the dust generated during cutting in a timely manner to keep the working environment clean.

[0036] Cutting direction adjustment

[0037] If the cutting direction needs to be adjusted, the operator can hold the handle 15 on the top of the rotating disk 7 and rotate the rotating disk 7. The rotating disk 7 rotates in the sliding groove 14 of the fixed ring 13 through the sliding ring 12, which drives the fixed shell 2, the protective body 1 and the internal cutting machine assembly 4 to rotate together, thereby adjusting the cutting direction. After the adjustment is completed, the cutting operation can continue.

[0038] Equipment maintenance and cleaning

[0039] After the cutting operation is completed, stop the operation of the cutting machine assembly 4, operate the control panel 16 to raise the telescopic rod 5, raise the protective body 1 and the cutting machine assembly 4 to the initial position, open the opening and closing cover 10, clean and maintain the cutting machine assembly 4, check the wear of the saw blade, replace the saw blade in time if necessary, clean the dust and debris inside the protective body 1 and the dust suction pipe 9, close the opening and closing cover 10, and store the equipment properly for the next use.

[0040] The working principle of this utility model is as follows: When it is needed to cut rocks, the device is first hoisted to the surface of the rock to be cut by hoisting machinery. At this time, it is connected to the external power supply equipment to enable the cutting machine component 4 inside the protective body 1 to operate normally.

[0041] The opening and closing cover 10 and the protective body 1 are rotatably connected by a hinge 11. The opening and closing cover 10 is made of transparent material. When the opening and closing cover 10 is closed, the staff can observe the rock cutting operation. When the opening and closing cover 10 is open, the staff can perform maintenance and other operations on the cutting machine component 4.

[0042] The telescopic rod 5 can drive the protective body 1 and the cutting machine component 4 inside it to descend. At this time, the protective body 1 actively descends relative to the fixed shell 2, so that the saw blade of the cutting machine component 4 can cut into the rock well. Meanwhile, the telescopic rod 5 can be electrically driven or hydraulically driven and connected to external equipment through the connector 6. It can provide a stable downward force to the cutting machine component 4, making the overall rock cutting process more stable and safe.

[0043] When the protective body 1 descends relative to the fixed shell 2, the springs 304 in the four sets of elastic support mechanisms 3 are passively contracted, further improving the overall stability. At the same time, when the protective body 1 does not descend, the sum of the elastic forces of the four sets of springs 304 is greater than the sum of the weights of the protective body 1 and the cutting machine assembly 4, thus avoiding the problem of the saw blade of the cutting machine assembly 4 remaining off the ground when not cutting, thus preventing damage to the saw blade.

[0044] The rotating disk 7 can drive the fixed shell 2, the protective body 1 and its internal components to adjust the angle relative to the fixed ring 13, thereby better adjusting the cutting direction of the saw blade of the cutting machine component 4. The overall use effect is more convenient. The operator only needs to use two sets of handles 15 to rotate the rotating disk 7 to adjust the angle, avoiding the need to use external hoisting machinery to adjust the angle of this equipment again.

[0045] Furthermore, when cutting rocks, the opening and closing cover 10 is in a closed state. As the protective body 1 and the cutting machine assembly 4 descend relative to the fixed shell 2, the end of the opening and closing cover 10 is also passively and gradually extended into the interior of the fixed shell 2. In other words, when the equipment is running, the opening and closing cover 10 is limited by the fixed shell 2 and cannot be opened, thus avoiding the danger to the workers when the equipment is running. The overall safety is good.

[0046] Furthermore, a dust suction pipe 9 is installed on the top of the protective body 1. The dust suction pipe 9 is connected to an external air suction device through a pipe, so that the dust generated during rock cutting can be quickly absorbed, thereby avoiding the harm caused to the workers by the cutting dust.
