Description

Technical Field

[0001] The invention relates to the technical field of shearing machines, and in particular to a shearing device. Background Art

[0002] At present, the safety situation in mines is very severe, especially in hot work, and the safety management requirements are getting higher and higher. Strict hot work management aims to prevent the occurrence of safety accidents such as fire and explosion, and to ensure the safety of mine workers and the integrity of equipment and facilities.

[0003] In mines, wire ropes are usually cut by oxygen cutting. Especially when working at the shaft mouth, oxygen cutting will produce a lot of slag. If workers do not operate properly, the slag is easy to fall and cause a fire. Oxygen cutting belongs to the category of hot work, which increases the fire hazard and does not meet the increasingly stringent mine safety regulations.

[0004] Another common way to cut wire rope is to use a cutting machine. Risk of cutting blades breaking and flying out: During operation, the cutting machine is prone to causing the cutting blades to break and fly out, causing unpredictable harm to on-site workers. Cutting with a cutting machine also falls into the category of hot work, which poses a fire hazard and does not meet the current strict hot work management requirements.

[0005] Traditional wire rope cutting methods (such as oxygen cutting and cutting machine cutting) have significant safety hazards in mining environments and are difficult to meet the current strict mining safety standards. Therefore, a new, non-hot, high-safety wire rope cutting technology is urgently needed to ensure the safety and compliance of mining operations. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a shearing device to reduce the number of times a mine uses a steel wire rope and improve operational safety.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0035] According to an embodiment of the present invention, a shearing device is provided, Figures 1 to 4 As shown, it includes a driving mechanism, a knife seat 4, and a blade 3. The driving mechanism has a fixed end and a telescopic end. The knife seat 4 is connected to the fixed end of the driving mechanism through a connecting member 2, and a notch 41 is provided on the side of the knife seat 4 relative to the telescopic end of the driving mechanism. The blade 3 is connected to the telescopic end of the driving mechanism, and the blade 3 corresponds to the notch 41 of the knife seat 4. The blade 3 is used to move relative to the notch 41 under the drive of the driving mechanism to cut the rope. The side of the notch 41 away from the blade 3 is set as an arc end, and the side of the notch 41 relative to the blade 3 is set as an open end. When the blade 3 moves relative to the notch 41, the blade 3 squeezes the rope to the arc end of the notch 41 and cuts the rope.

[0036] In the above-mentioned shearing device, the side of the notch 41 away from the blade 3 is set as an arc-shaped end. This design allows the rope to better fit the arc-shaped surface when being cut, increases the cutting contact area, reduces the cutting resistance, and thus improves the cutting efficiency. When the blade 3 moves relative to the notch 41, the rope is first squeezed to the arc-shaped end of the notch 41, and then cut. This method of squeezing first and then cutting can ensure that the rope has been fixed and tightened before cutting, reducing the risk of slippage and incomplete cutting during the cutting process.

[0037] The knife holder 4 is connected to the fixed end of the driving mechanism through the connecting piece 2, which ensures that the whole device has high structural stability during operation. Especially under high load or long-term working conditions, this fixed connection can reduce vibration and shaking and extend the service life of the equipment. The blade 3 corresponds to the notch 41 of the knife holder 4, and the blade 3 moves relative to the notch 41 under the drive of the driving mechanism. This precise positioning method ensures the consistency and accuracy of each cutting action and reduces operational errors. The notch 41 is set as an open end on the side opposite to the blade 3. This design is not only convenient for putting in and taking out the rope, but also can avoid unnecessary damage to other parts or operators during the cutting process.

[0038] Since the blade 3 and the blade holder 4 are designed to be relatively closed (except for the open end), the possibility of the blade being exposed is reduced to a certain extent, thereby improving the safety of operation. This design is suitable for ropes of different diameters and materials, whether it is a wire rope or a fiber rope, and can achieve effective cutting by adjusting the force and speed of the driving mechanism.

[0039] The material selection of the blade 3 and the knife holder 4 usually considers high-strength alloy steel or tool steel, which has high hardness and wear resistance after special treatment, can remain sharp during long-term use, and adapt to various complex working environments. The design of the notch 41 allows the debris after cutting to be discharged smoothly without remaining inside the device, reducing the difficulty of cleaning. The modular design of the blade 3 and the knife holder 4 facilitates replacement and maintenance, reducing maintenance costs and time.

[0040] A sliding groove 5 is provided on the connecting member 2, and the direction of the sliding groove 5 is the same as the telescopic direction of the driving mechanism. The blade 3 is slidably mounted on the sliding groove 5 and can slide along the sliding groove 5, which facilitates the sliding of the blade 3 and ensures that the blade will not shift during operation and that there will be no jamming during operation.

[0041] The blade 3 includes a blade positioning portion 31 , a blade body 32 and a cutting portion 33 . The blade positioning portion 31 is fixed to the telescopic end of the driving mechanism. The blade body 32 is connected between the blade positioning portion 31 and the cutting portion 33 . The cutting portion 33 corresponds to the notch 41 .

[0042] The horizontal cross section of the cutting portion 33 is provided in an arc shape.

[0043] The thickness of the cutting portion 33 gradually decreases from the side away from the notch 41 to the side close to the notch 41, so that the cutting portion 33 is "V"-shaped, so that the blade can apply force more concentratedly during the cutting process, thereby effectively improving the cutting efficiency. In this way, a steel wire rope with a maximum diameter of 60 mm can be cut at one time.

[0044] A first positioning hole is provided on the blade positioning portion 31 , and a second positioning hole is provided on the telescopic end of the driving mechanism. The first positioning hole and the second positioning hole are connected by screws.

[0045] A fixing plate 6 is provided at the top of the knife holder 4, and the fixing plate 6 is provided corresponding to the notch 41. A diameter measuring sensor and a material identification sensor are provided on the fixing plate 6. The diameter measuring sensor, such as a laser rangefinder sensor or an ultrasonic sensor, is used to measure the diameter of the wire rope. The material identification sensor, such as an infrared spectrometer or an electromagnetic induction sensor, is used to identify the material of the wire rope. A controller is provided on the fixed end of the driving mechanism, and the output ends of the diameter measuring sensor and the material identification sensor are respectively connected to the input end of the controller. The controller is used to receive the signals transmitted by the diameter measuring sensor and the material identification sensor and control the telescopic speed and telescopic stroke of the driving mechanism based on the signals.

[0046] The diameter measuring sensor on the fixed plate 6 is activated immediately after the wire rope enters the notch 41. The sensor measures the diameter of the wire rope and transmits the data to the controller. The controller automatically adjusts the extension speed and stroke of the drive mechanism according to the measured diameter value to ensure the best cutting effect.

[0047] The material recognition sensor on the fixing plate 6 is activated when the steel wire rope enters the notch 41 to identify the material of the steel wire rope (such as steel, fiber, etc.). The sensor transmits the recognition result to the controller. The controller further optimizes the cutting parameters according to the material recognition result, such as adjusting the cutting force and cutting speed to adapt to steel wire ropes of different materials.

[0048] The controller generates specific driving instructions based on the diameter and material information and sends them to the driving mechanism. The driving mechanism performs telescopic actions according to the instructions to move the blade 3 relative to the notch 41. The blade 3 first squeezes the wire rope to the arc-shaped end of the notch 41, and then cuts it to ensure a smooth and efficient cutting process. During the entire cutting process, the controller monitors the data of the diameter measurement sensor and the material identification sensor in real time to ensure that the cutting parameters are always in the optimal state. If an abnormal situation is detected (such as diameter changes or inconsistent materials), the controller will immediately adjust the action of the driving mechanism to avoid damage to the equipment or affect the cutting quality. When the cutting is completed, the driving mechanism returns to the initial position and prepares for the next cutting operation. The controller records the relevant data of this cutting, including diameter, material, cutting time, and parameter settings, for subsequent analysis and maintenance.

[0049] By integrating diameter measurement sensors and material recognition sensors, the shearing device can realize intelligent detection and cutting of wire ropes. The controller dynamically adjusts the cutting parameters based on the real-time data provided by the sensors to ensure that each cutting operation achieves the best results. This intelligent design not only improves cutting efficiency and quality, but also extends the service life of the equipment and reduces maintenance costs.

[0050] The driving mechanism includes a hydraulic cylinder 1, which is connected to a hydraulic pump station through a hydraulic oil inlet pipe and a hydraulic oil return pipe. The present invention uses a hydraulic station as a power source and an oil cylinder as a power source, and starts the hydraulic station to give power to the oil cylinder, thereby cutting the wire rope.

[0051] A plate or tube and shell heat exchanger is installed on the hydraulic oil return pipe, and the plate or tube and shell heat exchanger exchanges heat with the hydraulic oil inlet pipe. The recovered heat energy is used to preheat the hydraulic oil in a cold environment, improve the fluidity at startup, and enable the device to operate normally in the cold winter.

[0052] Install an accumulator between the hydraulic pump and the actuator. You can choose between gas-filled accumulators (such as nitrogen bottles) or spring-loaded accumulators, the former being more common and more efficient. The system pressure is monitored by a pressure sensor, and when the pressure exceeds the set value, the excess energy is automatically stored in the accumulator; when the pressure is below the set value, the stored energy is released to replenish the system. When the hydraulic system pressure is high, the accumulator is used to store excess hydraulic energy; when the system needs additional energy, the hydraulic energy in the accumulator is released.

[0053] It is also possible to deploy a variety of sensors such as pressure, flow, and temperature to comprehensively monitor the operating parameters of the hydraulic system. Based on the collected data, intelligent algorithms such as fuzzy logic and neural networks are used to optimize the energy recovery process. A closed-loop control system is established to adjust the energy recovery strategy in a timely manner according to actual working conditions to ensure the best energy-saving effect.

[0054] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
