Description

Technical Field

[0001] This utility model relates to the field of engineering construction, and in particular to a steel wire tape cutting device for hard rock. Background Technology

[0002] Currently, the main types of open-air and underground cavern rock cutting machinery include circular saws, diamond wire saws, and chain arm saws. Circular saws offer high cutting speeds, smooth straight cuts, and minimal error, making them suitable for various types of hard rock. However, their blade diameter limits their ability to cut thicker rock masses. Diamond wire saws are suitable for thicker hard rock, but require a pre-installed drilling rig, and the diamond beads wear out quickly, leading to high replacement costs. Their cutting efficiency is lower than circular or chain arm saws, and precise operation is crucial, demanding high-skill personnel. Chain arm saws can cut thicker rock, but their chain structure results in significant vibration during transmission, leading to tooth skipping, transmission failure, and inability to operate at high speeds. This results in prolonged friction between the cutter and the cutting surface, causing built-up edge formation, interfering with normal cutting, and increasing resistance, making them unsuitable for cutting hard rock (such as granite). Therefore, we propose a special steel wire tape cutting device for hard rock to address these issues. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a steel wire tape cutting device for hard rock, including an electric saw, a cutting device on the electric saw, the cutting device including a steel wire tape, the steel wire tape including polyurethane and multiple steel wire ropes, multiple blades on the polyurethane, multiple springs between two blades, the multiple blades being connected by steel wire ropes, and a tensioning device on the cutting device.

[0012] The beneficial effects of this utility model are as follows: the steel wire tape includes multiple blades. This device uses a steel wire tape, which adopts a belt transmission principle. The blades cut quickly, the friction time between the blades and the cutting body is short, there is no built-up edge formation, the cutting resistance is low, and it can adapt to cutting high-hardness rock masses.

[0026] Example 1:

[0027] like Figure 1-6 A wire mesh tape cutting device for hard rock includes an electric saw 1, a cutting device 2 on the electric saw 1, a wire mesh tape 4, a polyurethane 401, and multiple wire ropes 403. Multiple blades 5 are mounted on the polyurethane 401, and multiple springs 402 are located between two blades 5. The multiple blades 5 are connected by the wire ropes 403. A tensioning device 6 is provided on the cutting device 2. With this structure, the wire mesh tape 4 includes multiple blades 5. This device utilizes the wire mesh tape 4, which employs a belt conveyor principle. The blades 5 cut at high speeds, with short friction time between the blades 5 and the cutting surface, resulting in no built-up edge formation and low cutting resistance, making it suitable for cutting high-hardness rock.

[0028] The steel wire tape 4 is integrally cast from liquid polyurethane 401, assembled steel wire rope 403, and cutter 5, and has excellent wear resistance, tear resistance, and chemical resistance, thus extending the overall life of the device.

[0029] Multiple perforations 502 are arranged in the lower half of the base of the cutting tool 5. Steel wire rope 403 is inserted through the perforations 502 to give the steel wire tape 4 strong stability. Springs 402 are installed between the cutting tools 5. The springs 402 absorb the vibration during the cutting process, reduce the impact on the steel wire tape 4, avoid plastic deformation, and reduce the risk of fatigue fracture.

[0030] Multiple diamond particles 501 are uniformly brazed onto the upper part of the cutting substrate of the tool 5, which improves the holding force of the solder on the diamonds, and each diamond can effectively cut, thus improving the cutting performance of the tool 5.

[0031] The housing 201 is made of high-strength wear-resistant alloy, which connects the main pulley 3 and the steel wire belt 4 into a whole cutting device, extending the cutting depth and adapting to ultra-thick rock cutting.

[0032] The cutting device 2 is equipped with a tensioning device 6, which prevents the cutting device 2 from shaking, shifting or vibrating due to slack, thereby ensuring the accuracy of the cutting path, improving cutting precision, ensuring the stability of the cutting process, and providing a safer working environment for the operator.

[0033] In a preferred embodiment, the chainsaw 1 is equipped with a water tank 101 and a water pump 102, and the cutting device 2 is equipped with a nozzle 7. The cutting device 2 includes a housing 201. With this structure, the tensioning seat 601 of the tensioning device 6 is mounted on the housing 201, and the nozzle 7 is mounted on the housing 201.

[0034] In the preferred embodiment, the nozzle 7 is connected to the water pump 102, and the water tank 101 is connected to the water pump 102.

[0035] In a preferred embodiment, the cutting device 2 includes a main pulley 3 and a driven pulley 8, connected by a steel wire rope 4. The bottom of polyurethane 401 rests against either the main pulley 3 or the driven pulley 8. With this structure, the main pulley 3 includes a second rotating shaft, on which a cutting motor is mounted, and the cutting motor is installed between the main pulley 3 and the electric saw 1. In this structure, the steel wire rope 4 is integrally cast from liquid polyurethane 401, assembled steel wire rope 403, and the cutting tool 5. A protective layer of polyurethane 401 is formed on the surface of the steel wire rope 403, providing excellent wear resistance, tear resistance, and chemical resistance, thus extending the overall lifespan of the device.

[0036] In the preferred embodiment, multiple slag discharge and drainage channels 404 are provided on one side of the polyurethane 401. With this structure, when the cutting device 2 is working, the slag discharge and drainage channels 404 on the side of the polyurethane 401 drive the water pump 102, causing the nozzle 7 to spray water onto the steel wire tape 4. The water impacts the cut debris, preventing the steel wire tape 4 from becoming clogged. Simultaneously, the water sprayed from the nozzle 7 onto the steel wire tape 4 reduces the heat generated during operation, continuously carrying away absorbed heat and providing a sustained cooling effect, thus extending the service life of the steel wire tape 4.

[0037] In a preferred embodiment, the cutting tool 5 has multiple through holes 502, the steel wire rope 403 abuts against the through holes 502, and the top of the cutting tool 5 has multiple diamond particles 501. With this structure, multiple diamond particles 501 are uniformly brazed onto the cutting substrate on the upper part of the cutting tool 5, which improves the holding force of the solder on the diamonds, and each diamond can effectively cut, thereby improving the cutting performance of the cutting tool 5.

[0038] In a preferred embodiment, the tensioning device 6 includes a tensioning seat 601, a tensioning motor 602 mounted on the tensioning seat 601, a tension rod 604 at the output end of the tensioning motor 602, and a rotating shaft mounted on the pulley 8. The tension rod 604 is connected to the rotating shaft of the pulley 8. With this structure,

[0039] The tension motor 602 uses a constant torque output control method. By adjusting the output torque of the tension motor 602, the tension applied to the steel wire belt 4 from the pulley 8 can be precisely adjusted, maintaining the stability of the steel wire belt 4 during operation. When the tension rod 604 moves too much, the tension rod 604 abuts against the trigger pin at one end of the limit switch 603, and the tension motor 602 stops the swing of the tension rod 604, preventing the tension rod 604 from moving beyond its design range and causing an accident.

[0040] The limit switch 603 is equipped with a sensor, which can be a line sensor or an angle sensor. When the sensor is a line sensor, the distance between the sensor and the tension rod 604 is measured and converted into the angle of the tension rod 604 swinging relative to the horizontal line. The sensor measures the angle of the tension rod 604 swinging relative to the horizontal line, which facilitates the adjustment of the rotation speed of the cutting device 2 and the tension control of this invention.

[0041] In a preferred embodiment, the tensioning seat 601 is provided with a limit switch 603, which includes a trigger pin and a receiver. Therefore, the limit switch 603 includes a trigger pin and a receiver.

[0042] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
