The cable drum 7 is mounted on the mounting platform 3 by means of a drum support 71.
The self-moving cutting equipment provided by the invention is mainly used in mines and is beneficial to coal mining arranged in a roadway or pressure relief of roof cutting.
The self-moving cutting equipment mainly comprises a track system 1, a track system 2, a mounting platform 3, a chain cutter arm 5 with chain cutters 4, a hydraulic system 6 and a cable roller 7.
The track system 1 includes two parallel tracks 11, and two ends of each track 11 are provided with track leg cylinders 12, and the track leg cylinders 12 can extend and retract so as to raise or lower the tracks 11.
The track leg cylinder 12 includes a cylinder tube 121 and a piston leg 122, and the piston leg 122 is slidably connected to the cylinder tube 121. The cylinder 121 is fixedly connected to the rail 11.
When it is desired to raise the rail 1, the rail leg cylinder 12 is actuated and its piston leg 122 is extended, thereby causing the piston leg 122 to extend from the cylinder 121 and raise the rail 11. When it is desired to lower the rail 11, the rail leg cylinder 12 is actuated to retract the piston leg 122, thereby retracting the piston leg 122 into the cylinder 121 to lower the rail 11.
At least two platform support oil cylinders 31 which are arranged at intervals are arranged below the mounting platform 3. The platform support leg 31 includes a cylinder 311 and a piston leg 312, the piston leg 312 being slidably connected to the cylinder 311. The cylinder 311 is fixedly connected to the mounting platform 3, and is connected to the lower side of the mounting platform 3. The connecting frame 20 may be mounted on the cylinder 311.
The platform support legs 31 are used to raise and lower the mounting platform 3. When the platform support legs 31 are actuated such that the piston legs 312 are extended, the mounting platform 3 can be raised. When the platform support legs 31 are actuated to retract the piston legs 312, the mounting platform 3 can be lowered.
The mounting platform 3 is connected with the track 11 through the sliding driving connecting mechanism 8, and the mounting platform 3 and the track 11 can move relatively through the sliding driving connecting mechanism 8, so that self-moving is realized.
The crawler system 2, the chain cutter arm 5, the hydraulic system 6 and the cable drum 7 are respectively installed on the installation platform, so when the installation platform 3 moves on the track 11, the crawler system 2, the chain cutter arm 5, the hydraulic system 6 and the cable drum 7 move along with the installation platform 3.
Specifically, the track system 2 includes a track support frame 21 and a traveling track 22, and the traveling track 22 is provided on the track support frame 21. The track support frame 21 is connected to the mounting platform 3 by a connecting frame 20. The walking crawler 22 is used for driving the whole set of equipment to move, can quickly reach the position needing construction, and can quickly move in a roadway.
When the crawler system 2 works, the track support oil cylinder 12 and the platform support oil cylinder 31 are both retracted, the walking crawler 22 is in contact with the ground, and the self-moving cutting equipment is led to move.
With the track leg cylinders 12 and/or platform leg cylinders 31 extended, the walking tracks 22 are supported, which are separated from the ground. The self-moving cutting equipment can automatically move forwards to cut the top plate by the action of the connecting mechanism 8 driven by the alternate extension and sliding of the track supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31.
The chain cutter arm 5 is provided with a chain cutter arm rotating shaft 51, and the chain cutter arm rotating shaft 51 is rotatably installed at one side of the installation platform 3, so that the chain cutter arm 5 can rotate at one side of the installation platform 3. A chain blade arm driving motor 52 is installed on the installation platform 3, and the output end of the chain blade arm driving motor 52 is connected with the chain blade arm rotating shaft 51 to transmit power. The output end of the chain arm driving motor 52 and the chain arm rotating shaft 51 can be in gear connection transmission, belt connection transmission or direct transmission through coupling connection.
Thus, the link arm 5 can be rotated from the initial state (the link arm 5 is in the horizontal position) to the operating state (the link arm 5 is in the vertically upward position) and also can be rotated from the operating state back to the initial state by the drive of the link arm drive motor 52.
A hydraulic system 6 is mounted on the mounting platform 3 for providing hydraulic pressure to the track leg cylinders 12 and the platform leg cylinders 31. The track support oil cylinder 12 and the platform support oil cylinder 31 are respectively connected with the hydraulic system 7 through pipelines.
The cable drums 7 are mounted on the mounting platform 3 by drum supports 71 for winding cables which can be laid with the movement of the self-moving cutting apparatus to provide communication and power.
The cable roller 7 is arranged on a roller bracket 71 through a rotating shaft, and the roller bracket 71 is fixedly arranged on the mounting platform 3.
The self-moving control method of the self-moving cutting equipment comprises the following steps:
referring to fig. 10-13, the track support oil cylinder 12 and the platform support oil cylinder 31 are both retracted, the walking crawler 22 in the crawler system 2 is in contact with the ground, and the self-moving cutting equipment is driven to reach the construction position in the roadway by the rotation of the walking crawler 22.
After the self-moving cutting equipment reaches the construction position in the roadway, the self-moving cutting equipment automatically moves forwards through the function of the connecting mechanism 8 driven by the alternate stretching and sliding of the rail supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31. Specifically, the rail support oil cylinder 12 is extended out, the platform support oil cylinder 31 is kept retracted, the walking crawler 22 is separated from the ground, and the rail support oil cylinder 12 supports the whole set of equipment. The mounting platform 3 is then driven to slide from end to end on the track 11 by the slide drive connection 8. After the mounting platform 3 is moved into position, the platform leg cylinders 31 are extended again, the track leg cylinders 12 are retracted, and the walking tracks 22 continue to move off the ground. At this time, the platform support oil cylinder 31 supports the whole set of equipment, and the track support oil cylinder 12 of the track 11 is also separated from the ground. The track 11 is then forced forward by the sliding drive connection 8. Since the mounting platform 3 is now supported and held stationary by the platform leg cylinders 31, the rails 11 move forward relative to the mounting platform 3 when the slide drive connection 8 is actuated.
After the track 11 moves forward to a proper position, the track supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31 alternately stretch and slide to drive the connecting mechanism 8 to actuate repeatedly, so that the self-moving cutting equipment moves forward in a roadway. After the forward movement is finished, the track supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31 are both retracted, at the moment, the walking crawler 22 is in contact with the ground, and the self-moving cutting equipment is driven to leave the roadway through the walking crawler 22.
When the sliding driving connecting mechanism 8 drives the mounting platform 3 to move forwards on the track 11, the chain cutter arm driving motor 52 can drive the chain cutter arm 5 to rotate upwards, the chain cutter 4 rotates on the chain cutter arm 5 for cutting, and the chain cutter moves forwards along with being driven by the mounting platform 3 to move forwards for cutting.
With reference to fig. 10-14, the operation method for cutting and decompressing the top plate by using the self-moving cutting equipment is as follows:
the track support oil cylinder 12 and the platform support oil cylinder 31 are both firstly folded, and the self-moving cutting equipment is driven to reach the designated position in the roadway 200 by the walking crawler belt 22 in the crawler belt system 2.
After the self-moving cutting apparatus reaches a designated position within the roadway 200, the rail leg cylinders 12 are extended, the platform leg cylinders 31 remain retracted, and the walking tracks 22 are moved off the ground. The track support cylinder 12 now supports the entire installation.
The mounting platform 3 is then driven to move on the rail 11 by the sliding drive connection mechanism 8, first to the first or rear end of the rail 11. The rear end is in relation to the cutting direction.
And then the chain cutter arm driving motor 52 drives the chain cutter arm 5 to rotate upwards, and the chain cutter 4 is cut into the top of the roadway inner wall 201 until the chain cutter arm 5 rotates to be vertical.
And the mounting platform 3 is driven to move forwards on the track 1 by the sliding driving connecting mechanism 8, and the chain cutter arm 5 and the chain cutter 4 are driven to move forwards to cut the fixed plate and the roadway inner wall 201. The distance that the mounting platform 3 moves forward on the track 1 can be set as desired, preferably the mounting platform 3 moves forward on the track 1 to the second or front end of the track 1.
After the mounting platform 3 is moved into position, the platform leg cylinders 31 are extended again, the track leg cylinders 12 are retracted, and the walking tracks 22 continue to move off the ground. The platform leg cylinder 31 now supports the entire plant.
The track 11 is driven forward by the sliding drive connection 8. Since the mounting platform 3 is now supported and held stationary by the platform leg cylinders 31, the rails 11 move forward relative to the mounting platform 3 when the slide drive connection 8 is actuated.
The distance that the rail 11 is moved forward can be set as desired, and preferably the rail 11 is moved forward to contact the mounting platform 3 at its first or rear end.
After the track 11 moves forward to a proper position, the track supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31 alternately stretch and slide to drive the connecting mechanism 8 to actuate repeatedly, so that the self-moving cutting equipment moves forward in a roadway and drives the chain cutter 4 to cut forward.
After cutting is completed, the chain cutter arm 5 is rotated to the initial position, then the track support oil cylinder 12 and the platform support oil cylinder 31 are both retracted, and the crawler system 2 works to drive the self-moving cutting equipment to leave the roadway 200 through the walking crawler 22.
Therefore, the self-moving cutting equipment provided by the invention can be moved to a construction position through the crawler system, then the track and the mounting platform can alternately advance through the alternate extension and retraction of the track support oil cylinder and the platform support oil cylinder in cooperation with the sliding driving connecting mechanism, the self-moving is realized, the cutting is carried out by the chain cutter during the passing, the coal mining is conveniently moved in the coal mining, the working efficiency is improved, and the cost is saved.
Preferably, as shown in fig. 3 and 5, the sliding drive connection mechanism 8 includes a mechanism gear 81, a mechanism rack 82, a mechanism rotating shaft 83, and a mechanism drive motor 84 for driving the mechanism rotating shaft to rotate.

After the self-moving cutting equipment reaches the construction position in the roadway, the self-moving cutting equipment automatically moves forwards through the function of the connecting mechanism 8 driven by the alternate stretching and sliding of the rail supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31. Specifically, the rail support oil cylinder 12 is extended out, the platform support oil cylinder 31 is kept retracted, the walking crawler 22 is separated from the ground, and the rail support oil cylinder 12 supports the whole set of equipment. The mounting platform 3 is then driven to slide from end to end on the track 11 by the slide drive connection 8. After the mounting platform 3 is moved into position, the platform leg cylinders 31 are extended again, the track leg cylinders 12 are retracted, and the walking tracks 22 continue to move off the ground. At this time, the platform support oil cylinder 31 supports the whole set of equipment, and the track support oil cylinder 12 of the track 11 is also separated from the ground. The track 11 is then forced forward by the sliding drive connection 8. Since the mounting platform 3 is now supported and held stationary by the platform leg cylinders 31, the rails 11 move forward relative to the mounting platform 3 when the slide drive connection 8 is actuated.
After the track 11 moves forward to a proper position, the track supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31 alternately stretch and slide to drive the connecting mechanism 8 to actuate repeatedly, so that the self-moving cutting equipment moves forward in a roadway. After the forward movement is finished, the track supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31 are both retracted, at the moment, the walking crawler 22 is in contact with the ground, and the self-moving cutting equipment is driven to leave the roadway through the walking crawler 22.

S202: the track leg cylinders 12 are extended and the platform leg cylinders 31 remain retracted and the walking tracks 22 are moved off the ground.
S203: the mounting platform 3 is driven to move to the first end of the track 11 by the sliding drive connection 8.
S204: the chain cutter arm driving motor 52 drives the chain cutter arm 5 to rotate upwards, and the chain cutter 4 is cut into the top of the roadway inner wall 201 until the chain cutter arm 5 rotates to be vertical.
S205: the mounting platform 3 is driven to move forwards on the track 1 by a third preset distance through the sliding driving connecting mechanism 8, and the chain cutter arm 5 and the chain cutter 4 are driven to move forwards for cutting.
S206: after the mounting platform 3 has moved the third predetermined distance, the platform leg cylinders 31 are extended and the track leg cylinders 12 are retracted while allowing the walking tracks 22 to continue off the ground.
S207: the track 11 is driven forward by the sliding drive connection 8 a fourth preset distance.
S208: repeating the steps S202-S207 until the specified path is walked;
s209: the chain cutter arm 5 is rotated to the initial position, the track support oil cylinder 12 and the platform support oil cylinder 31 are both retracted, the crawler system 2 works, and the self-moving cutting equipment is driven to leave through the walking crawler 22.
When the sliding driving connecting mechanism 8 drives the mounting platform 3 to move forwards on the track 11, the chain cutter arm driving motor 52 can drive the chain cutter arm 5 to rotate upwards, the chain cutter 4 rotates on the chain cutter arm 5 for cutting, and the chain cutter moves forwards along with being driven by the mounting platform 3 to move forwards for cutting.
With reference to fig. 10-14, the operation method for cutting and decompressing the top plate by using the self-moving cutting equipment is as follows:
the track support oil cylinder 12 and the platform support oil cylinder 31 are both firstly folded, and the self-moving cutting equipment is driven to reach the designated position in the roadway 200 by the walking crawler belt 22 in the crawler belt system 2.
After the self-moving cutting apparatus reaches a designated position within the roadway 200, the rail leg cylinders 12 are extended, the platform leg cylinders 31 remain retracted, and the walking tracks 22 are moved off the ground. The track support cylinder 12 now supports the entire installation.
The mounting platform 3 is then driven to move on the rail 11 by the sliding drive connection mechanism 8, first to the first or rear end of the rail 11. The rear end is in relation to the cutting direction.
And then the chain cutter arm driving motor 52 drives the chain cutter arm 5 to rotate upwards, and the chain cutter 4 is cut into the top of the roadway inner wall 201 until the chain cutter arm 5 rotates to be vertical.
And the mounting platform 3 is driven to move forwards on the track 1 by the sliding driving connecting mechanism 8, and the chain cutter arm 5 and the chain cutter 4 are driven to move forwards to cut the fixed plate and the roadway inner wall 201. The distance that the mounting platform 3 moves forward on the track 1 can be set as desired, preferably the mounting platform 3 moves forward on the track 1 to the second or front end of the track 1.
After the mounting platform 3 is moved into position, the platform leg cylinders 31 are extended again, the track leg cylinders 12 are retracted, and the walking tracks 22 continue to move off the ground. The platform leg cylinder 31 now supports the entire plant.
The track 11 is driven forward by the sliding drive connection 8. Since the mounting platform 3 is now supported and held stationary by the platform leg cylinders 31, the rails 11 move forward relative to the mounting platform 3 when the slide drive connection 8 is actuated.
The distance that the rail 11 is moved forward can be set as desired, and preferably the rail 11 is moved forward to contact the mounting platform 3 at its first or rear end.
After the track 11 moves forward to a proper position, the track supporting leg oil cylinder 12 and the platform supporting leg oil cylinder 31 alternately stretch and slide to drive the connecting mechanism 8 to actuate repeatedly, so that the self-moving cutting equipment moves forward in a roadway and drives the chain cutter 4 to cut forward.
After cutting is completed, the chain cutter arm 5 is rotated to the initial position, then the track support oil cylinder 12 and the platform support oil cylinder 31 are both retracted, and the crawler system 2 works to drive the self-moving cutting equipment to leave the roadway 200 through the walking crawler 22.
When the chain cutter arm 5 is in a vertical state, the mounting platform 5 is controlled to slide forwards along the track 11 for cutting, finally, a gap with the cutting depth of 6m and the cutting width of 40mm is formed in the top of the downwind roadway 200, and the purpose of dividing the pressure of the top plate into two parts is achieved. When the coal mining surface 100 moves along the pressure relief direction of the top plate, the top plate is divided into two parts due to the gap formed by cutting. The downwind tunnel 200 is naturally maintained and the return air tunnel 300 is buried in the goaf. Therefore, the downwind tunnel 200 can be reserved on the next coal mining surface for continuous use, so that the construction of the coal tunnel is reduced, the coal pillar-free mining process is realized, and the coal mining rate and the coal mining efficiency are greatly improved.
Preferably, in step S206, after the mounting platform 3 moves forward on the rail 11 by the third preset distance, the protrusion 33 on the front side of the mounting platform 3 contacts the elastic buffer 14 on the front connecting plate 13. In step S207, when the rail 11 moves forward by a fourth preset distance, the rear protrusion 33 of the mounting platform 3 contacts the rear elastic buffer 14 on the connecting plate 13.
The convex portion 311 collides with the elastic buffer 14 to play a role in buffering, so as to avoid hard contact between the two parts and play a role in protection.
In conclusion, the self-moving cutting equipment, the control method and the top-cutting pressure-relief operation method provided by the invention can be moved to a construction position through the crawler system, then the track and the mounting platform can alternately advance through the alternate extension and retraction of the track support oil cylinder and the platform support oil cylinder in cooperation with the sliding driving connection mechanism, so that self-moving is realized, the cutter chain cuts when the cutter chain is switched on, the coal mining can be conveniently moved in coal mining, the working efficiency is improved, and the cost is saved.
According to the needs, the above technical schemes can be combined to achieve the best technical effect.
The foregoing is considered as illustrative only of the principles and preferred embodiments of the invention. It should be noted that, for those skilled in the art, several other modifications can be made on the basis of the principle of the present invention, and the protection scope of the present invention should be regarded.
