Description

Technical Field

[0001] This utility model relates to the field of underwater rock and soil cutting, and in particular to a floating platform underwater chain arm saw cutting device. Background Technology

[0002] Traditional underwater cutting techniques (such as blasting and high-pressure water jetting) suffer from low efficiency, high cost, significant environmental impact, and low safety, and are difficult to adapt to complex underwater terrain. Chain arm saws, on the other hand, employ low-speed planing, minimizing spark generation and allowing safe operation even in hazardous environments like high-gas mines, offering higher safety compared to blasting or high-pressure water jetting. Chain arm saws are also environmentally friendly and offer high cutting efficiency. Due to their high efficiency, high yield, and good equipment stability, chain arm saws have relatively low maintenance costs, resulting in a lower overall cost. However, chain arm saws are difficult to operate underwater, requiring specialized divers for underwater operation and maintenance. Underwater operations pose significant safety risks, such as decompression sickness and drowning for divers. Furthermore, underwater operation of chain arm saws involves water currents that exert impact and drag forces, making it difficult for operators to adjust the cutting position based on the rock conditions and control the cutting point and path of the chain arm saw. This impacts the accuracy and efficiency of underwater rock and soil cutting operations. Therefore, we propose a floating platform underwater chain arm saw cutting device to solve the above problems.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a floating platform underwater chain arm saw cutting device, including a floating platform, a slide rail mechanism on one side of the floating platform, a drive device on the slide rail mechanism, the drive device being connected to the slide rail mechanism, a moving platform on the top of the slide rail mechanism, a lifting device on the moving platform, and a chain arm saw on the top of the lifting device.

With this structure, the slide rail mechanism 2 is mounted on the floating platform 1, the moving platform 3 is mounted on the top of the slide rail mechanism 2, and the slide rail mechanism 2 is connected to the drive device 4, allowing the floating platform 1 to float on the water surface. By controlling the position of the floating platform 1, the approximate cutting position of the chain saw 6 can be controlled. This avoids the need for workers to operate the chain saw 6 underwater, preventing divers from facing risks such as decompression sickness and drowning. The chain saw 6 features high efficiency, high yield, environmental friendliness, good equipment stability, relatively low maintenance costs, and low overall cost, resulting in high overall cutting efficiency and low operating costs.

[0026] By driving the motor 401 of the drive unit 4 to move the belt 404, the slider 203 of the slide rail mechanism 2 slides relative to the track 201, and the moving platform 3 slides relative to the floating platform 1, so as to adjust the horizontal cutting point of the chain saw 6 and control the forward path of the chain saw 6.

[0027] By driving the second motor 504 of the lifting device 5, the upper rotating seat 508 slides relative to the upper slide rail 503, the lower rotating seat 507 slides relative to the lower slide rail 506, the plate 501 rises and falls relative to the moving platform 3, and the chain arm saw 6 rises and falls, thereby controlling the vertical cutting point of the chain arm saw 6. This avoids the situation where workers have difficulty adjusting the cutting position of the chain arm saw 6 in real time according to the rock, resulting in low accuracy and low efficiency in the cutting operation.

[0028] In a preferred embodiment, the floating platform 1 is equipped with multiple propulsion devices 101, which are either propellers or water jets. Multiple anchors 102 are also provided on the floating platform 1. This structure allows the floating platform 1 to adopt a modular pontoon structure, equipped with a balance adjustment system to adapt to wave effects. The propulsion devices 101 are either propellers or water jets, and the anchors 102 cooperate with the propulsion devices 101 for positioning and movement of the floating platform 1. The chainsaw 6 includes a main gearbox and a chainsaw arm. Both the electrical control box 7 and the hydraulic control box 8 are connected to the chainsaw 6.

[0029] In a preferred embodiment, the slide rail mechanism 2 includes two rails 201, with multiple U-shaped connecting rods 202 between the two rails 201. Multiple sliders 203 are mounted on the rails 201, and the sliders 203 are connected to the bottom of the moving platform 3. With this structure, the sliders 203 are connected to the slide table 301 of the moving platform 3, the two rails 201 are connected by the multiple U-shaped connecting rods 202, and the U-shaped connecting rods 202 are connected to the floating platform 1.

[0030] In a preferred embodiment, the drive device 4 includes a motor 401 and a belt 404. The output end of the motor 401 is provided with a main pulley 402, and a driven pulley 403 is provided on one side of the main pulley 402. The driven pulley 403 and the main pulley 402 are connected by the belt 404.

[0031] In a preferred embodiment, the belt 404 is provided with an L-shaped connecting plate 405, which is connected to multiple sliders 203 on one side. The motor 401 is mounted on the U-shaped connecting rod 202. This structure drives the motor 401 of the drive unit 4, causing the main wheel 402 to rotate, which in turn moves the belt 404, moves the connecting plate 405, and causes the multiple sliders 203 to move horizontally, thereby allowing the moving platform 3 and the chain arm saw 6 to move horizontally.

[0032] In a preferred embodiment, the mobile platform 3 includes a slide 301, on which a vertical plate 302 is provided. The vertical plate 302 has multiple vertical grooves 303, and multiple ribs 304 are provided on one side of the vertical plate 302. In this structure, the ribs 304 support the vertical plate 302. An electrical control box 7 and a hydraulic control box 8 are mounted on the slide 301, and the bottom of the slide 301 is connected to the sliders 203 of the multiple slide rail mechanisms 2.

[0033] In a preferred embodiment, the lifting device 5 includes a flat plate 501, a lower slide rail 506, and two forks 502. Multiple protrusions are provided on one side of the flat plate 501, and these protrusions slide against the vertical groove 303. This structure drives the second motor 504 of the lifting device 5, causing the lead screw 505 to rotate. This causes the coupling between the two lower rotating seats 507 to move horizontally, which in turn causes the lower rotating seats 507 and the upper rotating seat 508 to move horizontally. This causes the forks 502 to rise and fall, and the flat plate 501 to rise and fall relative to the vertical plate 302, thus allowing the chain saw 6 to rise and fall vertically. This controls the vertical cutting point of the chain saw 6, preventing situations where workers cannot easily adjust the cutting position of the chain saw 6 according to the rock surface, thus avoiding low accuracy and efficiency in the cutting operation.

[0034] In a preferred embodiment, one top end of the fork 502 is rotatably connected to the plate 501, and the other top end of the fork 502 is provided with an upper rotating seat 508.

One bottom end of the fork 502 is rotatably connected to the moving platform 3, and the other bottom end of the fork 502 is provided with a lower rotating seat 507, which is slidably connected to a lower slide rail 506. With this structure, a protrusion on one side of the plate 501 slides against the vertical groove 303, thereby limiting the position of the plate 501.

[0035] In a preferred embodiment, a second motor 504 is provided at the bottom of the flat plate 501, and a lead screw 505 is provided at the output end of the second motor 504. A coupling frame is provided between the two lower rotating seats 507, and a threaded hole is provided on the coupling frame.

With this structure, the second motor 504 is mounted on the moving platform 3, and both the lower rotating seat 507 and the upper rotating seat 508 are provided with horizontal grooves. The lower slide rail 506 abuts against the horizontal groove of the lower rotating seat 507, and the upper slide rail 503 abuts against the horizontal groove of the upper rotating seat 508.

[0036] In the preferred embodiment, the mobile platform 3 is equipped with an electrical control box 7 and a hydraulic control box 8, both of which are connected to the chain saw 6. With this structure, the hydraulic control box 8 is equipped with a waterproof sealing device and uses pressure-resistant oil pipes and corrosion-resistant materials. The electrical control box 7 is equipped with an underwater leakage protection module and a remote control interface; the chain arm cutting chain of the chain saw 6 is coated with a seawater corrosion-resistant coating and integrates a real-time lubrication system; the chain saw 6 is equipped with an underwater camera, pressure sensor, and alarm device to monitor the cutting status and equipment operating parameters in real time.
