Description

Technical Field

[0001] The present invention relates to the technical field of water jet cutting devices, and particularly to a downhole mobile hydraulic control water jet device. Background Art

[0002] Some of the coal blocks mined in the mine are relatively large in volume, which are inconvenient to directly load onto trucks or transfer through conveyor belts. They need to be cut and segmented. To avoid spark generation in the mine and cause gas explosion accidents, cold cutting technology is generally used for cutting coal blocks. Among the equipment applying cold cutting technology, high-pressure water cutting machines are widely used. And to facilitate the transfer of the cutting machine in the mine, it is generally set in a movable form.

[0003] To prevent debris from flying and hurting people and water from splashing and hurting people during the cutting process, water jet cutting devices are mostly equipped with components for blocking and protecting against flying debris. And to facilitate observing the cutting situation through the blocking components in real time, the blocking components are mostly set in a transparent form;

[0004] Most of the existing water jet cutting devices lack a mechanism for cleaning the transparent blocking components in real time during the cutting process, resulting in the transparent blocking components being easily splashed, soiled, and blocked by coal slag or black water mixed with coal slag, affecting transparency and preventing workers from observing the cutting conditions at any time;

[0005] In addition, although some cutting devices are equipped with mechanisms for cleaning the transparent blocking and protecting components, most of these mechanisms need to be manually operated additionally, which is rather troublesome to use. Summary of the Invention

Two U-shaped connection frames are symmetrically welded on the positioning sleeve in the up and down direction. And the head end of the telescopic rod of the hydraulic cylinder is rotatably connected to the lower U-shaped connection frame together. The tail end of the pull rod is rotatably connected to the upper U-shaped connection frame together.

And the head end of the pull rod is rotatably connected to the U-shaped frame together. And the head ends of the two connecting rods are correspondingly rotatably connected to the two L-shaped mounting shafts together.

[0020] In at least some embodiments,

Among them, the rear wheels are universal wheels, and a short connecting pipe for horizontal longitudinal support is welded at the middle position of the rear side of the chassis of the jet device.

[0022] In at least some embodiments,

[0023] The two horizontal positioning shafts at the top are hollow and are provided with two rows of spray holes that spray obliquely towards the transparent baffle, and a water receiving member is welded to the left side of the two horizontal positioning shafts at the top.

[0024] In at least some embodiments,

[0025] The water receiving member is integrally composed of a U-shaped water distribution pipe and an L-shaped water inlet pipe welded to the middle bottom position of the U-shaped water distribution pipe.

The cobalt metal round block slides left and right following the magnetic ring, and the valve shaft axially slides and is inserted into the shaft groove for cooperation.

[0028] The present invention provides an underground mobile hydraulically controlled water jet device, which has the following beneficial effects:

[0029] When the present invention is in use, through the power transmission of the pull rod, when the swing pipe is driven by the hydraulic cylinder to swing up and down for cutting, it can drive the two scrubbing frames to slide towards each other left and right to clean the front and back sides of the two transparent baffles in real time. During the cutting process, the two transparent baffles always remain relatively clean and have a certain transparency. Compared with the prior art lacking a cleaning mechanism for the transparent blocking components, it can avoid the transparent blocking components being easily splashed, wetted, polluted and blocked by coal slag or black water mixed with coal slag, affecting transparency, which is beneficial for workers to observe the cutting conditions at any time. In addition, it can also save the trouble of manually driving the two scrubbing frames to scrub and clean frequently, and is more convenient and labor-saving to use.

[0030] In addition, the two horizontal positioning shafts at the top can spray cleaning water on the transparent baffle through two rows of spray holes on them to assist the two scrubbing frames in scrubbing and cleaning, which helps to thoroughly clean the impurities on the transparent baffle. This enables the two horizontal positioning shafts at the top to have not only the function of positioning and installing the two scrubbing frames but also the function of spraying and cleaning water, with the effect of dual-purpose use.

[0031] In addition, under normal conditions, the spring can push and position the magnetic ring to the initial state of sliding to the right, and keep the valve shaft in the use state of being plugged and blocked with the shaft groove. When the left scrubbing frame slides to the left, the top part of it abuts against the stress shaft and drives the magnetic ring and the valve shaft to slide to the left to open the passage between the U-shaped water distribution pipe and the L-shaped water inlet pipe to supply water to the two horizontal positioning shafts at the top. When the left scrubbing frame slides to the right and separates from the stress shaft, the spring on the shaft sleeve can push the magnetic ring and the valve shaft to slide to the right and reset to cut off the water supply to the top horizontal positioning shaft. Repeating this way can achieve intermittent supply of the sprayed cleaning water, which helps to reduce the waste of cleaning water.

[0032] In addition, as a component for driving the opening and closing of the valve shaft, the magnetic ring is indirectly connected to the valve shaft through magnetic suction force in space. Compared with the transmission method of directly fixing and connecting the two components together to transmit the driving force, it can save the holes or grooves on the shaft sleeve for the connection structure between the two components to slide, which helps to ensure the complete sealing of the shaft sleeve, and there is no need to consider the problem of relative movement sealing between the two components and the shaft sleeve.

Through this mechanism, the telescopic sliding of the telescopic rod of the hydraulic cylinder 7 can drive the swing pipe 3 to swing up and down, performing swing cutting on large-volume coal blocks. And through the power transmission of the pull rod 303, when the swing pipe 3 is driven by the hydraulic cylinder 7 to swing up and down for cutting, it can also drive the two brushing frames 2 to slide towards each other left and right to clean the front and back sides of the two transparent baffles 104 in real time, so that the two transparent baffles 104 always remain relatively clean and have a certain transparency during the cutting process. Compared with the prior art lacking a cleaning mechanism for the transparent blocking components, it can avoid the transparent blocking components being easily splashed, wetted, polluted and blocked by coal slag or black water mixed with coal slag, affecting the transparency, which is beneficial for workers to observe the cutting conditions at any time. In addition, it can also save the trouble of manually driving the two brushing frames 2 to brush and clean frequently, and is more convenient and labor-saving to use.

The head end of the pull rod 303 is rotatably connected to the U-shaped frame 801, and the head ends of the two connecting rods 201 are correspondingly rotatably connected to the two L-shaped mounting shafts 802.

[0071] In the embodiment of the present disclosure,

[0072] A total of three wheels are installed at the bottom of the front left and right sides and the middle bottom of the rear end of the chassis 6 of the jet device. The rear wheel is a universal wheel. A short connecting pipe 601 horizontally and longitudinally supported is welded at the middle position of the rear side of the chassis 6 of the jet device. A high-pressure water guide hose is connected between the head end of the short connecting pipe 601 and the tail end of the swing pipe 3. The tail end of the short connecting pipe 601 is connected to an external high-pressure water supply system.

[0073] In the embodiment of the present disclosure,

[0074] The two top horizontal positioning shafts 103 are hollow and are provided with two rows of spray holes that spray obliquely towards the transparent baffle 104. A water receiving member 5 is welded on the left side of the two top horizontal positioning shafts 103. The two top horizontal positioning shafts 103 can spray cleaning water on the transparent baffle 104 through the two rows of spray holes to assist the two scrubbing frames 2 in scrubbing and cleaning, which helps to thoroughly clean the impurities on the transparent baffle 104. This enables the two top horizontal positioning shafts 103 to have the function of spraying water for cleaning in addition to the function of positioning and installing the two scrubbing frames 2, achieving the use effect of one device with two functions.

[0075] In the embodiment of the present disclosure,

[0076] The water receiving member 5 is integrally composed of a U-shaped water distribution pipe and an L-shaped water inlet pipe 501 welded at the middle bottom position of the U-shaped water distribution pipe. The bottom side part of the vertical support pipe section of the L-shaped water inlet pipe 501 is fixed to the left vertical support rod of the vertical support frame 1. The head end of the horizontal pipe section of the L-shaped water inlet pipe 501 is connected to an external cleaning water supply system. The external cleaning water enters the two top horizontal positioning shafts 103 through the L-shaped water inlet pipe 501 and the U-shaped water distribution pipe.

[0077] Embodiment 2, on the basis of Embodiment 1, as Figure 8 - Figure 11As shown, the water receiving member 5 is integrally composed of a U-shaped water distribution pipe, a shaft sleeve 502 welded to the middle part of the U-shaped water distribution pipe, and an L-shaped water inlet pipe 501 welded to the bottom side of the tail end of the shaft sleeve 502. The shaft sleeve 502 is horizontally supported, and a magnetic ring 503 is slidably sleeved on the shaft sleeve 502 by spring pushing. A force-bearing shaft 504 that supports to the right is fixed in the middle of the top end of the magnetic ring 503.

[0078] In the embodiment of the present disclosure, a shaft groove is provided in the tail end part of the shaft sleeve 502. The U-shaped water distribution pipe, the shaft sleeve 502, and the L-shaped water inlet pipe 501 are interconnected in the shaft groove. A cobalt metal round block 505 is slidably installed inside the shaft sleeve 502. A valve shaft 506 is welded through the center of the cobalt metal round block 505. The cobalt metal round block 505 slides left and right following the magnetic ring 503. The valve shaft 506 slides and is inserted into the shaft groove in a matching manner. When the valve shaft 506 is inserted into the shaft groove, the passage between the U-shaped water distribution pipe and the L-shaped water inlet pipe 501 can be blocked. The valve shaft 506 and the cobalt metal round block 505 can be magnetically attracted by the magnetic ring 503 to drive left and right to open and close the passage between the U-shaped water distribution pipe and the L-shaped water inlet pipe 501. The magnetic ring 503 is installed by spring pushing on the shaft sleeve 502. Under normal conditions, the spring can push and position the magnetic ring 503 in the initial state of sliding to the right, and keep the valve shaft 506 in the use state of being inserted into and blocking the shaft groove. When the left brush frame 2 slides to the left, the top part of it abuts against the force-bearing shaft 504 and drives the magnetic ring 503 and the valve shaft 506 to slide to the left to open the passage between the U-shaped water distribution pipe and the L-shaped water inlet pipe 501 to supply water to the two top horizontal positioning shafts 103. When the left brush frame 2 slides to the right and separates from the force-bearing shaft 504, the spring on the shaft sleeve 502 can push the magnetic ring 503 and the valve shaft 506 to slide to the right and reset to cut off the water supply to the top horizontal positioning shaft 103. Repeating like this can achieve intermittent supply of the sprayed cleaning water, which helps to reduce the waste of cleaning water. The magnetic ring 503, as a component for driving the opening and closing of the valve shaft 506, is indirectly connected to the valve shaft 506 through magnetic attraction across space. Compared with the transmission method of directly fixing and connecting the two components together to transmit the driving force, it can save the need to open holes or grooves on the shaft sleeve 502 for the connection structure between the two components to slide, which helps to ensure the complete sealing of the shaft sleeve 502, and there is no need to consider the problem of relative movement sealing between the two components and the shaft sleeve 502.

[0079] The working principle of this embodiment is as follows: the tail end of the short pipe 601 is connected to an external high-pressure water supply system, and the high-pressure cutting water enters the swing pipe 3 through the high-pressure water hose between the short pipe 601 and the swing pipe 3, and the swing pipe 3 and the telescopic rod of the hydraulic cylinder 7 are connected together to form a crank rocker mechanism, through which the telescopic sliding movement of the telescopic rod of the hydraulic cylinder 7 can drive the swing pipe 3 to swing up and down, and implement swing cutting for large-volume coal blocks. During the cutting process, the rear part of the device should be twisted left and right to adjust the cutting angle to complete the cutting and segmenting of the large-volume coal blocks as a whole;

[0080] Through the power transmission of the pull rod 303, when the swing pipe 3 is driven by the hydraulic cylinder 7 to swing up and down for cutting, the T-shaped slider 8 can be driven to slide up and down, and the two brushing frames 2 can be indirectly driven to slide left and right to brush and clean the front and back surfaces of the two transparent baffles 104, so that the two transparent baffles 104 can always be kept relatively clean and transparent during the cutting process. Compared with the existing technology that lacks a transparent blocking component cleaning mechanism, it is convenient for workers to observe the cutting conditions at any time;

[0081] The two horizontal positioning shafts 103 at the top can spray cleaning water to the transparent baffle 104 through the two rows of spray holes thereon to assist the two brushing frames 2 in brushing and cleaning, and the external cleaning water enters the two horizontal positioning shafts 103 at the top through the L-shaped water inlet pipe 501 and the U-shaped water distribution pipe;

[0082] When the valve shaft 506 is inserted into the shaft groove, the passage between the U-shaped water distribution pipe and the L-shaped water inlet pipe 501 can be blocked, and the valve shaft 506 and the cobalt metal block 505 can be driven by the magnetic attraction of the magnetic ring 503 to slide left and right to switch the passage between the U-shaped water distribution pipe and the L-shaped water inlet pipe 501, and the magnetic ring 503 is pushed and installed by the spring on the shaft sleeve 502. Under normal circumstances, the spring can push the magnetic ring 503 to the initial state of sliding to the right, and keep the valve shaft 506 in the use state of being plugged and blocked with the shaft groove, and when the brush frame 2 on the left side is moved to the right, the valve shaft 506 can be opened and closed. When it slides to the left, its top part comes into contact with the force-bearing shaft 504 and drives the magnetic ring 503 and the valve shaft 506 to slide to the left to open the passage between the U-shaped water distribution pipe and the L-shaped water inlet pipe 501 to supply water to the two horizontal positioning shafts 103 at the top. When the left brush frame 2 slides to the right and separates from the force-bearing shaft 504, the spring on the shaft sleeve 502 can push the magnetic ring 503 and the valve shaft 506 to slide to the right to reset and cut off the water supply to the top horizontal positioning shaft 103. This can be repeated to achieve intermittent supply of spray cleaning water and reduce waste of cleaning water.
