Description

Technical Field

[0001] The invention relates to the technical field of anti-collapse support devices, in particular to an anti-collapse support device for metal or non-metal mining. Background Art

[0002] Mining is a science and technology of extracting mineral resources from the earth's crust or surface. The mining industry is an important raw material industry. Metal ores are the main raw materials for the smelting industry, and non-metallic ores are important chemical raw materials and building materials. According to the different burial depths of the ore deposits and the requirements of technical and economic rationality, mining technology is divided into open-pit mining and underground mining. Open-pit mining is used for parts close to the surface and shallowly buried, and underground mining is used for deep parts.

[0003] Underground mining is very dangerous. Whether it is digging metal or non-metal mines, collapse is very likely to occur. Therefore, underground mining requires the use of support devices to support the mine and reduce the occurrence of collapse. Existing support devices generally include guard plates and legs. Since the height of the legs is generally fixed, it is impossible to change the length of the legs according to the specific excavation conditions of the mine. Therefore, it is necessary to continuously increase the thickness or number of pads to adapt to changes inside the mine. However, after the pads are increased to a certain height, since the pads and legs can slide relative to each other, when the number of pads reaches a certain level, the legs and pads are prone to relative sliding under the action of external forces, affecting the support of the guard plates for metal or non-metal mines, and there are certain safety hazards.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When it is necessary to support a metal or non-metal mine hole, the fixed support is fixed at the required position by an expansion bolt, and then the torque of the first screw is transmitted to the second screw through the cooperation among the connecting key, the first through hole, the second through hole, the spline, and the keyway, and then the first screw is rotated on the first slider to drive the second screw to rotate with the first screw, and the first slider and the second slider are driven to move inward at the same time through the cooperation among the first screw, the second screw, the second slider, the first slider, the movable support, the connecting block, and the fixed support, and at the same time, the movable support is driven to slide on the fixed support through the connecting block until the support plate contacts the metal or non-metal mine hole, thereby playing the role of supporting the metal or non-metal mine hole;

[0018] When the height of the metal or non-metal mine cave changes, the first screw is further rotated to drive the second screw to rotate, thereby driving the two movable pillars to slide on the fixed pillars at the same time, so as to adjust the height of the legs, thereby supporting metal or non-metal mine caves of different heights, improving the supporting effect of the support plate on the metal or non-metal mine cave under any circumstances, and reducing the safety hazards in the metal or non-metal mine cave;

[0019] When there is an inclination angle on the top of the metal or non-metal mine cave, the fixed pillar connected to the first screw is first moved to a higher position, and the fixed pillar connected to the second screw is moved to a lower position. After the support plate is raised to a certain height by rotating the first screw, the connecting key connecting the first connecting plate and the second connecting plate is then removed, so that the first screw can rotate relative to the second screw, thereby only driving the movable pillar connected to the first screw to move, and cooperating with the fixed block provided on the support plate to rotate and connect with one of the movable pillars, and the movable block slidably provided on the support plate to rotate and connect with the other movable pillar, the support plate will be driven to rotate around the intersection of the fixed block and the movable pillar, thereby changing the angle of the support plate, and then achieving support for metal or non-metal mine caves with different inclinations, improving the supporting effect of the support plate on the metal or non-metal mine cave under any circumstances, and reducing the safety hazards in the metal or non-metal mine cave; at the same time, through the rotation connection of the second screw and the groove, the position of the first screw and the second screw is prevented from being offset, so as to facilitate the subsequent simultaneous adjustment of the positions of the two movable pillars;

[0020] 2. When the position of the connection key needs to be changed, a force greater than the rebound force of the first spring is applied to the connection key, and the first ball, the first groove, and the first spring cooperate to move the first ball inward, so that the connection key can move relative to the second connection plate until it passes through the through hole of the first connection plate, thereby realizing the connection between the first connection plate and the second connection plate, thereby adjusting the positions of the two movable pillars at the same time, changing the heights of the two legs, and realizing the support of metal or non-metal mine caves at different heights, thereby improving the support effect of the support plate on the metal or non-metal mine caves under any circumstances, and reducing the potential safety hazards in the metal or non-metal mine caves; or the connection key slides out of the first connection plate, releasing the connection between the first connection plate and the second connection plate, and only adjusting the height of the movable pillar connected to the first screw, thereby changing the angle of the support plate, thereby realizing the support of metal or non-metal mine caves with different inclinations, thereby improving the support effect of the support plate on the metal or non-metal mine caves under any circumstances, and reducing the potential safety hazards in the metal or non-metal mine caves;

[0021] After adjusting the position of the connecting key and reconnecting the first connecting disk and the second connecting disk, the first rotating disk is rotated to drive a plurality of sliding bars to slide on the second connecting disk through the cooperation among the first ball, the first groove, the first rotating disk, the first wedge block, the first inclined surface and the sliding rod. Until the sliding rod contacts the first ball, the first ball is restricted from sliding on the second connecting disk. The resistance generated by the contact between the first ball and the first groove will restrict the connecting key from sliding relative to the second connecting disk, so as to avoid the external force from acting on the connecting key accidentally and driving it to slide on the second connecting disk, causing the first screw and the second screw to slide. The connection relationship of the rods changes, which affects the overall stability of the support device, thereby improving the support effect of the support plate on the metal or non-metal mine cave under any circumstances, and reducing the potential safety hazards in the metal or non-metal mine cave; in addition, by rotating the third screw on the first turntable, the second ball connected to the end of the third screw is in contact with the corresponding second groove, thereby achieving the fixation of the first turntable relative to the second connection plate, further improving the overall stability of the support device, thereby improving the support effect of the support plate on the metal or non-metal mine cave under any circumstances, and reducing the potential safety hazards in the metal or non-metal mine cave;

[0022] 3. When the movable support is moved upward on the fixed support, the support block will be driven to slide relative to the guide sleeve. Through the cooperation among the support block, the second wedge block, the third wedge block, the second inclined surface, the limit block, the guide sleeve and the second spring, the support block can smoothly pass through the limit block without manually releasing the limit of the limit block, thereby simplifying the operation steps required for lifting the support legs and improving the efficiency of supporting metal or non-metal mines;

[0023] After adjusting the height of the legs, the pressure exerted on the support plate by the metal or non-metal mine is transmitted to the support block through the support plate and the movable legs. At this time, the support block is restricted from sliding downward relative to the fixed support through the cooperation between the support block, the second wedge block, the third wedge block and the plane, thereby bearing most of the force transmitted to the fixed support by the movable support, reducing the pressure on the connecting block, the first screw and the second screw, thereby improving the stability of the overall device, extending the service life of the support device, and further improving the supporting effect of the support plate on the metal or non-metal mine under any circumstances, reducing the safety hazards in the metal or non-metal mine;

[0024] When the height of the outrigger needs to be shortened, the fourth screw is rotated on the guide sleeve, and the third wedge-shaped block provided on one side of the limit block slides out from the support block through the cooperation among the guide sleeve, the T-block, the T-slot, the limit block, and the second spring, thereby releasing the restriction on the downward movement of the support block, so that the support block can be moved downward to shorten the height of the outrigger without having to manually move the limit block for a long time, thereby simplifying the operation steps required to shorten the outrigger, thereby improving the efficiency of supporting metal or non-metal mines;

[0025] 4. After adjusting the height of the support leg, if the second wedge block does not contact the plane provided on the upper side of the third wedge block, rotate the driving wheel, and through the cooperation among the support block, the driving wheel, the arc block, the second column, the third column, the second turntable, the first shaft, the driven wheel, the vortex groove, and the first column, drive the first column to move relative to the support block, thereby driving the support block to slide on the movable support until the top of the second wedge block contacts the plane provided on the upper side of the third wedge block, so that most of the force transmitted from the movable support to the fixed support is borne by the support block, reducing the pressure on the connecting block, the first screw and the second screw, thereby improving the stability of the overall device, extending the service life of the support device, and further improving the supporting effect of the support plate on the metal or non-metal mine cave under any circumstances, reducing the safety hazards in the metal or non-metal mine cave;

[0026] In addition, each time the second turntable is driven to rotate on the support block at a certain angle, the arc block contacts several second uprights at the same time, and the resistance generated will limit the rotation of the second turntable on the support block, thereby preventing the second turntable from being accidentally driven to rotate by external forces, causing the position of the support block relative to the fixed movable support to change, affecting the effect of the support block in bearing the force transmitted from the movable support to the fixed support, thereby improving the stability of the overall device, extending the service life of the support device, and further improving the supporting effect of the support plate on the metal or non-metal mine cave under any circumstances, reducing the safety hazards in the metal or non-metal mine cave;

[0027] In addition, through the cooperation between the vertical block, the second rotating shaft, the first vertical groove, the driving wheel and the second vertical groove, the rotation of the driving wheel relative to the second rotating shaft will be restricted, thereby preventing the driving wheel from accidentally rotating under the action of external force, thereby improving the supporting effect of the support plate on the metal or non-metal mine cave under any circumstances, and reducing the safety hazards in the metal or non-metal mine cave; finally, the nut is rotated at the end of the second rotating shaft to make it contact with the vertical block, thereby achieving the fixation of the vertical block, further improving the stability of the overall structure, improving the supporting effect of the support plate on the metal or non-metal mine cave under any circumstances, and reducing the safety hazards in the metal or non-metal mine cave.

[0056] Example 1

[0057] The present invention provides a support device for preventing collapse of metal or non-metal mines, such as Figure 1-3As shown, when it is necessary to support a metal or non-metal mine cave, the assembled support legs 2 and the support plate 1 are moved to the designated area in advance, and the fixed support 3 is fixed at the required position by the expansion bolts, and then the connecting key 18 is passed through the first through hole 16 and the second through hole 17, and the sliding connection of the spline 19 and the keyway 20 is cooperated to transfer the torque of the first screw 10 to the second screw 11, and then the first screw 10 is rotated on the first slider 7, driving the second screw 11 to rotate with the first screw 10, because the first screw 10 and the second screw 11 are respectively threadedly connected to the second slider 8, the second slider 8 will be driven to move relative to the first slider 7, and at the same time, because the first slider 7 and the second slider 8 are respectively rotatably connected with the connecting blocks 9 rotatably connected to the movable support 4, and the fixed support 3 guides the movable support 4, the first slider 7 and the second slider 8, the first slider 7 and the second slider 8 are driven to move inward at the same time, and at the same time, the movable support 4 is driven to slide on the fixed support 3 through the connecting block 9 until the support plate 1 contacts the metal or non-metal mine cave, thereby playing the role of supporting the metal or non-metal mine cave;

[0058] When the height of the metal or non-metal mine cave changes, the first screw 10 is further rotated to drive the second screw 11 to rotate, thereby driving the two movable pillars 4 to slide on the fixed pillar 3 at the same time, so as to adjust the height of the support leg 2, thereby achieving support for metal or non-metal mine caves of different heights, improving the support effect of the support plate 1 on the metal or non-metal mine cave under any circumstances, and reducing the safety hazards in the metal or non-metal mine cave;

[0059] When there is an inclination angle on the top of the metal or non-metal mine, first move the fixed support 3 connected to the first screw 10 to a higher position, and move the fixed support 3 connected to the second screw 11 to a lower position. After the support plate 1 is raised to a certain height by rotating the first screw 10, the connecting key 18 connecting the first connecting plate 12 and the second connecting plate 15 is then removed, so that the first screw 10 can rotate relative to the second screw 11, thereby only driving the movable support 4 connected to the first screw 10 to move, and cooperating with the fixed block 5 provided on the support plate 1 to rotate and connect with one of the movable supports 4, so as to The movable block 6 slidingly arranged on the support plate 1 is rotatably connected with another movable pillar 4, which will drive the support plate 1 to rotate around the intersection of the fixed block 5 and the movable pillar 4, thereby changing the angle of the support plate 1, and then realizing the support of metal or non-metal mine caves with different inclinations, improving the supporting effect of the support plate 1 on the metal or non-metal mine caves under any circumstances, and reducing the safety hazards in the metal or non-metal mine caves; at the same time, through the rotational connection of the second screw 11 and the groove 13, the position of the first screw 10 and the second screw 11 is avoided from being offset, which is convenient for the subsequent simultaneous adjustment of the positions of the two movable pillars 4.

[0060] Example 2

[0061] On the basis of Example 1, Figure 3 and Figure 4 As shown, when the position of the connecting key 18 needs to be changed, a force greater than the rebound force of the first spring 23 is applied to the connecting key 18, and the component force generated after the first ball 22 contacts the first groove 21 causes the first ball 22 to move inward and compress the first spring 23, so that the connecting key 18 can move relative to the second connecting plate 15 until it passes through the through hole of the first connecting plate 12, thereby realizing the connection between the first connecting plate 12 and the second connecting plate 15, thereby adjusting the positions of the two movable pillars 4 at the same time, changing the heights of the two legs 2, and realizing metal or Non-metal mine cave support, improve the support effect of the support plate 1 on metal or non-metal mine caves under any circumstances, and reduce the potential safety hazards in metal or non-metal mine caves; or the connecting key 18 slides out from the first connecting plate 12, releases the connection between the first connecting plate 12 and the second connecting plate 15, and only adjusts the height of the movable support 4 connected to the first screw 10, thereby changing the angle of the support plate 1, and then achieving support for metal or non-metal mine caves with different inclinations, improving the support effect of the support plate 1 on metal or non-metal mine caves under any circumstances, and reducing the potential safety hazards in metal or non-metal mine caves;

[0062] After adjusting the position of the connecting key 18 and reconnecting the first connecting disk 12 and the second connecting disk 15, the first ball 22 is re-entered into the first groove 21 by slightly moving the position of the connecting key 18, and the first rotating disk 25 is rotated so that the first inclined surfaces 27 provided on one side of the plurality of first wedge blocks 26 contact the end of the sliding rod 24, thereby driving the plurality of sliding rods 24 to slide on the second connecting disk 15 at the same time until the sliding rod 24 contacts the first ball 22, restricting the first ball 22 from sliding on the second connecting disk 15, and cooperating with the resistance generated by the contact between the first ball 22 and the first groove 21, the connecting key 18 is restricted from sliding relative to the second connecting disk 15, thereby preventing external force from accidentally acting on the connecting key 18 and driving it to slide on the second connecting disk 15, resulting in the connection of the first screw 10 and the second screw 11. The connection relationship changes, affecting the overall stability of the support device, thereby improving the supporting effect of the support plate 1 on the metal or non-metal mine cave under any circumstances, reducing the potential safety hazards in the metal or non-metal mine cave, and at the same time, there is no need to separately drive several slide rods 24 to move on the second connecting plate 15, which simplifies the operation steps of fixing several connecting keys 18 and improves the efficiency of the support device in supporting the metal or non-metal mine cave; in addition, by rotating the third screw 28 on the first turntable 25, the second ball 29 rotatably connected to the end of the third screw 28 is in contact with the corresponding second groove 30, thereby realizing the fixation of the first turntable 25 relative to the second connecting plate 15, further improving the overall stability of the support device, thereby improving the supporting effect of the support plate 1 on the metal or non-metal mine cave under any circumstances, and reducing the potential safety hazards in the metal or non-metal mine cave.

[0063] Example 3

[0064] On the basis of Example 2, Figure 5 and Figure 6 As shown, when the movable support 4 is moved upward on the fixed support 3, the support block 31 will be driven to slide relative to the guide sleeve 32, so that the plurality of second wedge blocks 33 provided on the support block 31 will contact with the third wedge block 35 in sequence, and the second wedge block 33 will contact with the second inclined surface 37 provided on the lower side of the third wedge block 35, and the generated force will drive the limit block 34 to move toward both sides, and compress the second spring 38 provided between the limit block 34 and the guide sleeve 32, so that the support block 31 can pass through the limit block 34 smoothly, without manually releasing the restriction of the limit block 34, thereby simplifying the operation steps required for lifting the support leg 2, and thereby improving the efficiency of supporting the metal or non-metal mine hole;

[0065] After adjusting the height of the support leg 2, the pressure exerted by the metal or non-metal mine on the support plate 1 is transmitted to the support block 31 through the support plate 1 and the movable support leg 2. At this time, the resistance generated by the contact between the second wedge blocks 33 provided on the support block 31 and the plane 36 provided on the upper side of the third wedge block 35 will further limit the downward sliding of the support block 31 relative to the fixed support pillar 3, thereby bearing most of the force transmitted to the fixed support pillar 3 by the movable support pillar 4, reducing the pressure on the connecting block 9, the first screw 10 and the second screw 11, thereby improving the stability of the overall device, extending the service life of the support device, and further improving the supporting effect of the support plate 1 on the metal or non-metal mine under any circumstances, reducing the safety hazards in the metal or non-metal mine;

[0066] When it is necessary to shorten the height of the leg 2, the fourth screw 39 is rotated on the guide sleeve 32 to move it outward on the guide sleeve 32 until one side of the T-block 40 contacts the T-slot 41, and drives the limit block 34 to slide on the guide sleeve 32, and compresses the second spring 38 until the third wedge block 35 provided on one side of the limit block 34 slides out of the support block 31, thereby releasing the restriction on the downward movement of the support block 31, so that the support block 31 can be moved downward, shortening the height of the leg 2, and there is no need to use the hand to move the limit block 34 for a long time, thereby simplifying the operating steps required to shorten the leg 2, thereby improving the efficiency of supporting metal or non-metal mines.

[0067] Example 4

[0068] On the basis of Example 1, Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, after adjusting the height of the support leg 2, if the second wedge block 33 does not contact the plane 36 provided on the upper side of the third wedge block 35, the driving wheel 49 is rotated on the support block 31, so that the arc block 50 provided on the upper side of the driving wheel 49 slides out from the plurality of second columns 48, and the restriction on the rotation of the second turntable 47 on the support block 31 is released. Then, the third column 51 contacts the second column 48, and the component force generated drives the second turntable 47 to rotate a certain angle on the support block 31. The above action is repeated many times, and the torque is transmitted through the first rotating shaft 46, which will drive the driven wheel 44 to rotate the required angle on the support block 31. At the same time, through the vortex groove provided on one side of the driven wheel 44 45 is in sliding contact with a plurality of first upright posts 42, and the component force generated drives the first upright posts 42 to move relative to the support block 31, thereby driving the support block 31 to slide on the movable pillar 4 until the top of the second wedge block 33 contacts the plane 36 provided on the upper side of the third wedge block 35, so that the support block 31 bears most of the force transmitted from the movable pillar 4 to the fixed pillar 3, reducing the pressure on the connecting block 9, the first screw 10 and the second screw 11, thereby improving the stability of the overall device, extending the service life of the support device, and further improving the supporting effect of the support plate 1 on the metal or non-metal mine cave under any circumstances, reducing the safety hazards in the metal or non-metal mine cave;

[0069] In addition, each time the second turntable 47 is driven to rotate a certain angle on the support block 31, the arc block 50 contacts with a plurality of second uprights 48 at the same time, and the resistance generated will limit the rotation of the second turntable 47 on the support block 31, thereby preventing the second turntable 47 from being accidentally driven to rotate by external forces, causing the position of the support block 31 to change relative to the fixed movable support 4, affecting the effect of the support block 31 in bearing the force transmitted from the movable support 4 to the fixed support 3, thereby improving the stability of the overall device, extending the service life of the support device, and further improving the supporting effect of the support plate 1 on the metal or non-metal mine cave under any circumstances, reducing the safety hazards in the metal or non-metal mine cave;

[0070] In addition, by sliding the vertical block 55 through the first vertical groove 53 provided on the second rotating shaft 52, so that it enters the second vertical groove 54 provided on the driving wheel 49, the resistance generated by the contact between the vertical block 55, the driving wheel 49 and the second rotating shaft 52 will limit the rotation of the driving wheel 49 relative to the second rotating shaft 52, thereby avoiding the driving wheel 49 from accidentally rotating under the action of external force, thereby improving the supporting effect of the support plate 1 on the metal or non-metal mine cave under any circumstances, and reducing the safety hazards in the metal or non-metal mine cave; finally, the nut 56 is rotated at the end of the second rotating shaft 52 to make it contact with the vertical block 55, thereby realizing the fixation of the vertical block 55, further improving the stability of the overall structure, improving the supporting effect of the support plate 1 on the metal or non-metal mine cave under any circumstances, and reducing the safety hazards in the metal or non-metal mine cave.
