Description

Technical Field

[0001] The present invention relates to the technical field of underground mining support, and specifically to an operating platform applicable to an uneven base surface. Background Technique

[0002] The mining method in mountain mines is the sublevel caving method with subsequent filling in sublevel stopes. Two or three sublevels are used for stoping, and the remaining two or one sublevel at the top is used for subsequent stoping. After the initial stoping blasting, the roof of the upper roadway is damaged to varying degrees, which has a greater impact on the subsequent upper-level stoping and filling. Considering the requirements of subsequent stope stoping and increasing the safety of stoping, the top of the underground sublevel caving stope needs to be supported multiple times during stoping.

[0003] When supporting the top during stoping, a hydraulic support is usually used to support the top. Through the hydraulic cylinders on both sides of the hydraulic support, the roof beam on the upper side of the hydraulic support is driven to move upward to support the roof, providing a construction operation platform for the staff. However, during the process of supporting the roof by the hydraulic support, local settlement or subsidence may occur on the foundation surface, resulting in ineffective transmission of the supporting force of the hydraulic support to the roof, affecting the supporting effect on the roof, and further affecting the supporting effect on the roof. Therefore, we propose an operating platform applicable to an uneven base surface. Summary of the Invention

Detailed implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1

[0038] Please refer to Figures 1 to 10 , the present invention provides a technical solution: an operating platform applicable to uneven ground surfaces, including: a hydraulic cylinder 11, and a top beam 12 is arranged on the upper side of each two hydraulic cylinders 11.

[0039] It further includes: a support assembly 2, the support assembly 2 is arranged on the top beam 12, and the support assembly 2 is used for supporting the roof of the underground roadway.

[0040] A detection assembly 3, the detection assembly 3 is arranged on the lower side of the support assembly 2, and the detection assembly 3 is used for detecting the inclination direction when the support assembly 2 supports the roof.

[0041] The regulating component 4 is arranged on one side of the top beam 12. When the foundation subsides, the regulating component 4 adjusts the supporting effect of the supporting component 2 on the roadway roof.

[0042] The recording component 5 is arranged on one side of the regulating component 4. The recording component 5 is used to record the adjustment limit of the regulating component 4 on the corresponding position of the supporting component 2 for multiple times.

[0043] There are three groups in total, with each two hydraulic cylinders 11 and the top beam 12 above them. When the supporting component 2 is used for retreating support of the underground roadway roof, by controlling the hydraulic cylinders 11, the top beam 12 is driven to move upward, so that the supporting component 2 firmly supports the roadway roof. During the process of supporting the roof by the supporting component 2, if the foundation subsides or sinks, the inclination direction of the supporting component 2 can be detected by the detection component 3, and then the hydraulic cylinders 11 in the corresponding direction are automatically controlled to work. And through the regulating component 4, the hydraulic cylinders 11 in the corresponding direction are automatically controlled to automatically restore the supporting effect on the roadway roof, so as to ensure the supporting effect on the underground roadway roof, and further ensure the supporting effect on the roof. Through the recording component 5, the adjustment amplitude can be recorded each time the regulating component 4 adjusts the supporting effect on the roadway roof. When the amplitude after multiple recordings reaches the limit of the recording component 5, the staff can be warned to remind the staff to check the foundation under the hydraulic cylinders 11 at this position to prevent further safety accidents.

[0044] The supporting component 2 includes first support plates 21 arranged on the front and rear top beams 12, and a second support plate 22 is arranged on the middle top beam 12. Limit blocks 23 are fixedly arranged on both sides of the upper ends of the three top beams 12. Limiting grooves 24 adapted to the limit blocks 23 are arranged on both sides of the first support plates 21 and the second support plate 22. The first support plates 21 and the second support plate 22 are respectively arranged on the top beams 12 through the limiting grooves 24 on both sides, and the first support plates 21 or the second support plate 22 are restricted and fixed through the limiting effect of the limit blocks 23 on the limiting grooves 24. Pressure sensors 25 are installed on both sides of the three top beams 12, and the pressure sensors 25 on both sides correspond to the hydraulic cylinders 11 on both sides respectively.

[0045] During use, the two first support plates 21 are respectively fixed to the second support plate 22 by bolts. By controlling the hydraulic cylinders 11 to work, the top beam 12 is driven to move upward, and the roadway roof is supported by the two first support plates 21 and the second support plate 22. Through the pressure sensors 25, the supporting force of the first support plates 21 and the second support plate 22 on the roadway roof can be detected.

[0046] The detection component 3 includes a housing 31 arranged on the lower side of the middle side top beam 12. Rods 32 fixedly connected to the second support plates 22 are fixedly arranged on both sides of the housing 31. A gravity ball 33 is arranged inside the housing 31. First mounting grooves 34 are arranged on the front, back, left, and right sides of the housing 31. Second mounting grooves 35 are arranged at four diagonal positions of the housing 31. First switches 36 are installed in the housing 31 within the first mounting grooves 34 and the second mounting grooves 35. An indicator light 37 is installed on the lower side of the housing 31;

[0047] During the support process, if the foundation settles or subsides, the first support plate 21 and the second support plate 22 will tilt, and further cause the housing 31 to tilt. When tilting occurs in the front-back direction, under the action of gravity, the gravity ball 33 will correspondingly roll into the first mounting groove 34 in the front-back direction and press against the first switch 36 therein, correspondingly controlling the front two hydraulic cylinders 11 and the middle two hydraulic cylinders 11, or the rear two hydraulic cylinders 11 and the middle two hydraulic cylinders 11 to work; when tilting occurs in the left-right direction, the gravity ball 33 will correspondingly roll into the first mounting groove 34 in the left-right direction and press against the first switch 36 therein, then correspondingly controlling the three hydraulic cylinders 11 on the left side, or the three hydraulic cylinders 11 on the right side to work; when tilting occurs in the front-left diagonal direction, the gravity ball 33 will roll into the second mounting groove 35 at the front-left position and press against the first switch 36 therein, controlling the front two hydraulic cylinders 11 and the left middle hydraulic cylinder 11 to work; when tilting occurs in the front-right diagonal direction, the gravity ball 33 will roll into the second mounting groove 35 at the front-right position and press against the first switch 36 therein, controlling the front two hydraulic cylinders 11 and the right middle hydraulic cylinder 11 to work; when tilting occurs in the rear-left diagonal direction, the gravity ball 33 will roll into the second mounting groove 35 at the rear-left position and press against the first switch 36 therein, controlling the rear two hydraulic cylinders 11 and the left middle hydraulic cylinder 11 to work; when tilting occurs in the rear-right diagonal direction, the gravity ball 33 will roll into the second mounting groove 35 at the rear-right position and press against the first switch 36 therein, controlling the rear two hydraulic cylinders 11 and the right middle hydraulic cylinder 11 to work;

[0048] When supporting the roadway roof, if the gravity ball 33 does not press against any of the first switches 36, the indicator light 37 will not light up, indicating that it is a stable support for the roadway roof at this time. During the support process, if the foundation settles, the gravity ball 33 will press against one of the first switches 36, and the indicator light 37 will be powered on and light up. Thus, during the support process, it is also possible to judge whether the foundation has settled through the lighting of the indicator light 37, which can also play a role in prompting the staff.

[0049] The control component 4 includes mounting shells 41 fixedly arranged on both sides of three roof beams 12 respectively. A first electromagnetic block 42 is fixedly arranged inside the mounting shell 41. The first electromagnetic blocks 42 in the six mounting shells 41 correspond to and are electrically connected to the six pressure sensors 25 respectively. A moving block 43 is slidably arranged inside the mounting shell 41. A second electromagnetic block 45 that repels the first electromagnetic block 42 is fixedly embedded on one side of the moving block 43. Guide rods 44 are symmetrically penetrated and slidably arranged on both sides of the moving block 43. Both ends of the guide rod 44 are fixed to the two inner sides of the mounting shell 41. A first spring 46 fixedly arranged on the inner side of the mounting shell 41 is fixedly arranged on one side of the moving block 43;

[0050] On the side of the moving block 43 close to the first electromagnetic block 42, there is a helical gear block 47 slidably arranged with the mounting shell 41. On the side of the helical gear block 47 close to the helical gear rod 411, there are helical gear protrusions. A guide groove 48 adapted to the helical gear block 47 is opened on the inner side of the mounting shell 41. The helical gear block 47 is slidably arranged along the guide groove 48. A second switch 410 is installed on the side of the helical gear block 47 close to the moving block 43. The moving block 43 can press the second switch 410. A second spring 49 fixedly arranged on the inner side of the mounting shell 41 is fixedly arranged on one side of the helical gear block 47;

[0051] On one side of the helical gear block 47, there is a helical gear rod 411 slidably arranged with the mounting shell 41. The helical gear rod 411 cooperates with the helical gear block 47. A chute 412 adapted to the helical gear rod 411 is opened on the inner side of the mounting shell 41. The helical gear rod 411 is slidably arranged along the chute 412. A third electromagnetic block 414 fixedly arranged with the mounting shell 41 is arranged on one side of the helical gear rod 411. After being electrified, the third electromagnetic block 414 can generate an adsorption effect on the helical gear rod 411. Third springs 413 fixedly arranged on the inner side of the mounting shell 41 are symmetrically fixedly arranged on one side of the helical gear rod 411. By controlling the energization of the third electromagnetic block 414, an adsorption effect on the helical gear rod 411 is generated, so that the helical gear rod 411 moves close to the third electromagnetic block 414, and the third spring 413 is compressed, so that the helical gear rod 411 disengages from the helical gear block 47. Under the elastic force of the second spring 49, the helical gear block 47 moves reversely and resets. After controlling the power-off of the third electromagnetic block 414, under the elastic force of the third spring 413, the helical gear rod 411 resets;

[0052] When controlling the hydraulic cylinder 11 to drive the roof beam 12 to move upward for supporting the roof, the pressure detected by the pressure sensor 25 will increase, causing the elastic sensitive element of the pressure sensor 25 to change, thereby changing its resistance value, increasing the resistance value in the connection circuit, and decreasing the current, resulting in a decrease in the repulsive force of the first electromagnet 42 on the second electromagnet 45. Under the elastic force of the first spring 46, the moving block 43 moves closer to the first electromagnet 42 and pushes the helical block 47 to move. The helical block 47 moves along the helical groove of the helical rod 411, and the second spring 49 elongates. During the support process, if the foundation settles or subsides, through the detection component 3, multiple hydraulic cylinders 11 in the corresponding direction can be controlled to work. When the foundation settles or subsides, the pressure detected by the pressure sensor 25 corresponding to the hydraulic cylinder 11 in the corresponding direction will decrease, causing the resistance value in the connection circuit to decrease compared to normal support, increasing the repulsive force of the first electromagnet 42 on the second electromagnet 45, causing the moving block 43 to move away from the first electromagnet 42. Blocked by the helical rod 411 against the helical block 47, the reverse movement and reset of the helical block 47 are restricted, so that the position of the helical block 47 during normal support can be maintained. When controlling the corresponding hydraulic cylinder 11 to work and restoring the support effect on the roadway roof, the pressure detected by the corresponding pressure sensor 25 will gradually increase, causing the repulsive force of the first electromagnet 42 on the second electromagnet 45 to gradually decrease. Under the action of the first spring 46, the moving block 43 moves closer to the first electromagnet 42. When the moving block 43 moves to press against the second switch 410 on one side of the helical block 47, the corresponding hydraulic cylinder 11 will be controlled to stop working, and at this time, it returns to the initial support effect on the roadway roof to ensure the support effect on the roof.

[0053] The recording component 5 includes a rack 51 fixed on one side of the moving block 43. A first gear 52 is meshed and connected on one side of the rack 51. A rotating rod 53 rotatably arranged at the bottom side of the installation shell 41 is fixedly arranged in the middle of the first gear 52. An installation disk 54 is fixedly arranged on the upper side of the rotating rod 53. Clamping blocks 55 are rotatably arranged on both sides of the installation disk 54. A fourth spring 56 fixedly arranged with the installation disk 54 is fixedly arranged inside the clamping block 55. When the foundation settles, the movement of the moving block 43 away from the first electromagnet 42 will drive the rack 51 to move, causing the first gear 52 to rotate, and then driving the rotating rod 53 and the installation disk 54 to rotate.

[0054] An incomplete gear 57 is provided on the outer side of the mounting disc 54. An inclined tooth groove that cooperates with the clamping block 55 is provided on the inner side of the incomplete gear 57. A support frame 59 fixedly provided on the bottom side of the mounting shell 41 is rotatably provided on the upper side of the incomplete gear 57. An annular groove 58 adapted to the support frame 59 is provided on the upper side of the incomplete gear 57. The incomplete gear 57 is rotatably provided through the annular groove 58 and the support frame 59, and the support frame 59 can support the incomplete gear 57. The rotation of the mounting disc 54 will drive the two clamping blocks 55 to rotate. Through the blocking action of the inclined tooth groove on the inner side of the incomplete gear 57 on the end of the clamping block 55, the incomplete gear 57 can be driven to rotate.

[0055] A second gear 510 is provided on one side of the incomplete gear 57. The incomplete gear 57 can mesh with the second gear 510. A connecting rod 511 fixedly provided on the bottom side of the mounting shell 41 is rotatably provided in the middle of the second gear 510. A pressing block 512 is fixedly provided on the upper side of the second gear 510. An installation column 513 fixedly provided on the bottom side of the mounting shell 41 is provided on one side of the second gear 510. A third switch 514 is installed on the side of the installation column 513 close to the pressing block 512. The pressing block 512 can press the third switch 514. A warning device 515 is installed on the lower side of the mounting shell 41;

[0056] The rotation of the incomplete gear 57 can drive the second gear 510 to rotate by a certain amplitude, and then drive the pressing block 512 to rotate away from the installation column 513. When the moving block 43 moves close to the first electromagnet 42, the rack 51 will drive the first gear 52 and the mounting disc 54 to rotate in the reverse direction. Under the blocking action of the other end face of the inclined tooth groove on the inner side of the incomplete gear 57 on the clamping block 55, the clamping block 55 will rotate close to the mounting disc 54, and the fourth spring 56 will be compressed. Thus, the reverse rotation of the mounting disc 54 will not drive the rotation of the incomplete gear 57. Thus, the regulation of the multiple settlements of the regulation assembly 4 can be recorded through the rotation amplitude of the pressing block 512. When the pressing block 512 rotates to press the third switch 514, it means that the amplitude after multiple recordings reaches the limit of the recording assembly 5, indicating that the number of settlements and the amplitude of the foundation under the lower part of the hydraulic cylinder 11 at this position are relatively large. Through the pressing action of the third switch 514, the warning device 515 can be controlled to work to warn the staff, so as to remind the staff to check the foundation under the lower part of the hydraulic cylinder 11 at this position to prevent the occurrence of further safety accidents.

[0057] Embodiment 2

[0058] As Figures 11 to 14 shown, in this embodiment, other structures remain unchanged. The difference from Embodiment 1 is:

[0059] Sliding frames 61 are fixedly arranged on the outer sides of the front and rear side roof beams 12. A support member 62 is slidably arranged on the sliding frame 61. A rotating plate 63 is rotatably arranged on one side of the support member 62. A locking mechanism is arranged between the rotating plate 63 and the support member 62 to lock and fix the rotating plate 63 and the support member 62 after the rotating plate 63 is rotated and closed. The locking mechanism is an existing common technology. A connecting shell 65 is fixedly arranged on the other side of the support member 62. A fourth electromagnet 68 is fixedly arranged in the connecting shell 65. A limiting tooth block 67 adsorbed by the fourth electromagnet 68 is slidably arranged in the connecting shell 65. The limiting tooth block 67 penetrates through one side of the connecting shell 65. A tooth rod member 64 matched with the limiting tooth block 67 is arranged on one side of the limiting tooth block 67. The tooth rod member 64 is fixedly arranged on the lower side of the roof beam 12. Symmetrically fixed on one side of the limiting tooth block 67 are fifth springs 69 fixedly arranged on the inner side of the connecting shell 65;

[0060] When the staff installs bolts or pads on the top of the roadway, or checks the support on the top, etc., the staff can rotate and open the rotating plate 63, put relevant materials or tools into the support member 62, so as to facilitate the staff to carry out inspections or construction operations. A control switch is installed inside the support member 62. By pressing the control switch, the fourth electromagnet 68 can be energized to generate an adsorption effect on the limiting tooth block 67, so that the limiting tooth block 67 disengages from the tooth rod member 64. At this time, the staff can adjust the position of the support member 62 as needed by moving the support member 62 along the sliding frame 61. After adjustment, press the control switch again to cut off the power supply of the fourth electromagnet 68. Under the elastic force of the fifth spring 69, the limiting tooth block 67 is engaged with the tooth rod member 64 to limit the movement of the support member 62. At the same time, the staff can also stand inside the support member 62 and use the support member 62 as needed, providing an operating platform for the staff and better assisting the staff.

[0061] A fixed shell 66 is fixedly arranged on the lower side of the connecting shell 65. A fifth electromagnet 611 is fixedly arranged in the fixed shell 66. A stop block 610 and an adsorption block 612 are respectively slidably arranged in the fixed shell 66. The stop block 610 penetrates upward through the bottom of the connecting shell 65. Symmetrically fixed on the inner side of the fixed shell 66 are fixed blocks 614. A slide rod 613 movably penetrating through the fixed blocks 614 is symmetrically fixed between the stop block 610 and the adsorption block 612. The slide rod 613 slides along the fixed blocks 614. Symmetrically fixed on the lower sides of the two fixed blocks 614 are sixth springs 615 fixedly arranged with the adsorption block 612;

[0062] When the foundation sinks or sinks, the movement of the moving block 43 away from the first electromagnetic block 42 will make the moving block 43 no longer press against the second switch 410 on the side of the bevel gear block 47, and then the fifth electromagnetic block 611 can be controlled to be energized to produce an adsorption effect on the adsorption block 612, so that the adsorption block 612, the sliding rod 613 and the stopper 610 move upward, and the sixth spring 615 is compressed, so that the stopper 610 moves upward to the inside of the connecting shell 65 and is located on the side of the limiting gear block 67 close to the fifth spring 69. The limiting gear block 67 is blocked by the stopper 610 to prevent the limiting gear block 67 from detaching from the gear rod member 64 when the foundation sinks or sinks, causing the support member 62 to slide along the sliding frame 61, thereby ensuring the limit fixation of the support member 62 and improving safety.
