The integrated underground power supply device for mining is usually hoisted into or out of the mine through a lifting device.

[0003] The existing integrated underground mine power supply device is lifted and lowered along the shaft during the lifting process. However, due to the limited space inside the shaft and the device being easily shaken when suspended in the air, it is easy for the outer wall of the device to collide with the inside of the shaft, which can easily cause damage to the device.

[0007] Furthermore, the top of the bellows sleeve is fixedly connected to the bottom of the fixed pipe seat, and the limiting rod is distributed outside the bellows sleeve in a ring shape.

[0008] Furthermore, the penetration rod passes through the interior of the transmission push plate, and the penetration rod is elastically connected to the transmission push plate via an adapter spring.

[0009] Furthermore, the outer side surface of the rolling wheel does not exceed the side surface of the power supply body, and the power supply body is connected to the lifting hook rope of the lifting equipment through the lifting ring body.

[0010] Furthermore, the lifting ring assembly also includes a laser ranging sensor, and the end of the penetration rod away from the connecting shaft is provided with a laser ranging sensor.

[0016] The present invention provides an underground integrated power supply device for mining, which has the following beneficial effects:

[0017] 1. In the underground integrated power supply device for mining, when the lifting equipment carries the power supply body to be lifted and lowered along the inside of the well, the lifting ring body is pulled out by the pulling force applied upward by the hook rope, so that the rolling wheel is extended outward and rolls against the inner wall of the well, so that the power supply body can be lifted and lowered stably, so as to prevent the power supply body from bumping during the lifting process. Moreover, when the rolling wheel passes through the uneven area through the elastic action of the adapting spring during the rolling process, the wear rod carrying the rolling wheel can be well adapted through the elastic action of the adapting spring, and when the wear rod is extended and retracted, the distance between its end and the medium box also changes accordingly. At this time, the distance change can be measured in real time by the laser ranging sensor, and the change of the well wall can be calculated based on the change of the distance size, thereby obtaining the size change of the well inner diameter.

[0018] 2. The underground integrated power supply device for mining, when the power supply body enters the shaft, the electric pulley carries the blocking plate to slide at the initial position to block the rolling wheel, at which time the rolling wheel is blocked and cannot extend outward. When the rolling wheel of the power supply body completely enters the shaft, the electric pulley carries the blocking plate to slide so that the blocking plate leaves the position of the rolling wheel, at which time the rolling wheel loses the blockage and extends out, thereby preventing the rolling wheel from extending before entering the shaft, causing the outer diameter of the power supply body to increase and causing a jam between the power supply body and the shaft.

DETAILED DESCRIPTION

[0025] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1-Figure 5As shown, the present invention provides a technical solution: an integrated underground power supply device for mining, comprising a power supply body 1 and a lifting ring assembly 2, the lifting ring assembly 2 is arranged around the power supply body 1, the lifting ring assembly 2 comprises a fixed pipe seat 201, a first piston rod 202, a push plate 203, a bellows sleeve 204, a limit rod 205, a medium transmission pipe 206, a medium box 207, a second piston rod 208, a transmission push plate 209, an adaptor spring 210, a penetration rod 211, a connecting shaft 212, a rolling wheel 213 and a lifting ring body 214, the interior of the fixed pipe seat 201 is penetrated by the first piston rod 202, and the bottom of the first piston rod 202 is connected to the push plate 203, the surface of the push plate 203 is fixed with a bellows sleeve 204 on the outer wall of the first piston rod 202, and the edge of the push plate 203 passes through the limit rod 205, the side of the fixed pipe seat 201 is connected to the medium transmission pipe 206, and the medium transmission pipe 206 The end is connected to a medium box 207, and the two sides of the medium box 207 are penetrated by a second piston rod 208, and the end of the second piston rod 208 is connected to a transmission push plate 209, and the upper and lower parts of the outer side of the transmission push plate 209 are fixed with an adaptor spring 210, and the inside of the adaptor spring 210 is penetrated by a penetration rod 211, and the end of the penetration rod 211 is rotatably connected to a rolling wheel 213 through a connecting shaft 212, and a lifting ring body 214 is fixed to the top of the first piston rod 202, the top of the bellows sleeve 204 is fixedly connected to the bottom of the fixed pipe seat 201, and the limit rod 205 is distributed in a ring shape on the outside of the bellows sleeve 204, the penetration rod 211 penetrates the inside of the transmission push plate 209, and the penetration rod 211 is elastically connected to the transmission push plate 209 through the adaptor spring 210, the outer side surface of the rolling wheel 213 does not exceed the side surface of the power supply body 1, and the power supply body 1 is connected to the lifting hook rope of the lifting equipment through the lifting ring body 214;

[0027] The specific operation is as follows: use the hook rope of the lifting equipment to hook the lifting ring body 214 to lift the power supply body 1. Figure 2 As shown, when lifting and lowering along the inside of the well, the lifting ring body 214 is subjected to the pulling force of the hook rope and carries the first piston rod 202 to slide up along the fixed pipe seat 201, so that the push plate 203 pushes the bellows sleeve 204 to compress it. When the bellows sleeve 204 is compressed, the transmission medium inside it enters the medium box 207 along the medium transmission pipe 206, so that the second piston rod 208 carries the transmission push plate 209, the adaptor spring 210, the piercing rod 211, the connecting shaft 212, and the rolling wheel 213 to extend outward, so that the rolling wheel 213 exceeds the side of the power source body 1 and abuts against the inner wall of the well. Since the well is usually circular, when the rolling wheel 213 abuts against the inner wall of the well, the rotation of the connecting shaft 212 and the thrust are used to adjust and dispatch itself, so that the rolling wheel 213 abuts against the inner wall of the well.

[0028] When the push plate 203 rises and pushes the bellows sleeve 204 to compress it, the push plate 203 slides along the outer wall of the limit rod 205. At the same time, the limit rod 205 is located outside the bellows sleeve 204, which can prevent the bellows sleeve 204 from expanding outward when the bellows sleeve 204 is compressed.

[0029] Based on the above description, when the lifting equipment carries the power source body 1 to be lifted and lowered along the inside of the shaft, the upward pulling force applied by the hook rope causes the lifting ring body 214 to be pulled out, so that the rolling wheel 213 extends outward and rolls against the inner wall of the shaft, so that the power source body 1 can be lifted and lowered stably to prevent the power source body 1 from being bumped during the lifting process, and during the rolling process of the rolling wheel 213, the elastic action of the adaptor spring 210 can be used to adapt well when the rolling wheel 213 passes through an uneven area.

[0030] like Figure 1-Figure 5 As shown, the lifting ring assembly 2 further includes a laser distance measuring sensor 215, and the end of the penetrating rod 211 away from the connecting shaft 212 is provided with the laser distance measuring sensor 215;

[0031] The specific operation is as follows: during the rolling process of the rolling wheel 213, the elastic action of the adapter spring 210 causes the adapter spring 210 to expand and contract as the area changes, thereby causing the penetration rod 211 to expand and contract accordingly. When the penetration rod 211 expands and contracts, the distance between its end and the medium box 207 also changes accordingly. At this time, the change in distance can be measured in real time by the laser ranging sensor 215, and the change in the well wall can be calculated based on the change in the distance size, thereby obtaining the change in the size of the inner diameter of the well.

[0032] like Figure 1-Figure 5 As shown, both sides of the power supply body 1 are provided with a limit assembly 3, the limit assembly 3 includes an upper slide rail 301 and a lower slide rail 302, the lower slide rail 302 is arranged in parallel below the upper slide rail 301, the lower slide rail 302 is fixed to the bottom of the side of the power supply body 1, and the number of the lower slide rail 302 and the upper slide rail 301 are two respectively, the limit assembly 3 also includes an electric pulley 303, the lower slide rail 302 and the upper slide rail 301 are both slidably connected with the electric pulley 303, the limit assembly 3 also includes a blocking plate 304, the surface of the electric pulley 303 is fixed with a blocking plate 304, the blocking plate 304 is against the outer surface of the rolling wheel 213, and the number of the blocking plates 304 is consistent with the number of the rolling wheels 213;

[0033] The specific operation is as follows. When the power supply body 1 enters the interior of the well from top to bottom, or from bottom to top, in order to prevent the upper and lower sets of rolling wheels 213 from extending at the same time, resulting in the power supply body 1 not fully entering the well, so that the rolling wheels 213 extend outside the well and cause a jamming problem, when the power supply body 1 enters the well, the electric pulley 303 carries the blocking plate 304 to slide at the initial position to block the rolling wheels 213. At this time, the rolling wheels 213 are blocked and cannot extend outward. When the part where the rolling wheels 213 of the power supply body 1 are located fully enters the well, the electric pulley 303 carries the blocking plate 304 to slide so that the blocking plate 304 leaves the outside where the rolling wheels 213 are located. At this time, the rolling wheels 213 lose the blockage and extend out, thereby preventing the rolling wheels 213 from extending before entering the well, resulting in the outer diameter of the power supply body 1 becoming larger and causing a jamming between the well, wherein the control method of the electric pulley 303 is remote control control, and its principle is consistent with the control principle of the remote control car, both of which realize the movement of the electric pulley 303 or the remote control car through remote control.

[0034] In summary, when the underground integrated power supply device for mining is used, the hook rope of the lifting equipment is firstly used to hook the lifting ring body 214 to lift the power supply body 1, and the power supply body 1 is Figure 2 As shown, when lifting and lowering along the inside of the well, the lifting ring body 214 is subjected to the pulling force of the hook rope and carries the first piston rod 202 to slide up along the fixed pipe seat 201, so that the push plate 203 pushes the bellows sleeve 204 to compress it. When the bellows sleeve 204 is compressed, the transmission medium inside it enters the medium box 207 along the medium transmission pipe 206, so that the second piston rod 208 carries the transmission push plate 209, the adaptor spring 210, the piercing rod 211, the connecting shaft 212, and the rolling wheel 213 to extend outward, so that the rolling wheel 213 exceeds the side of the power source body 1 and abuts against the inner wall of the well. Since the well is usually circular, when the rolling wheel 213 abuts against the inner wall of the well, the rotation of the connecting shaft 212 and the thrust are used to adjust and dispatch itself, so that the rolling wheel 213 abuts against the inner wall of the well.

[0035] When the power supply body 1 enters the well from top to bottom or from bottom to top, in order to prevent the upper and lower sets of rolling wheels 213 from extending at the same time, resulting in the power supply body 1 not fully entering the well, so that the rolling wheels 213 extend outside the well and cause a jamming problem, when the power supply body 1 enters the well, the electric pulley 303 carries the blocking plate 304 to slide at the initial position to block the rolling wheels 213. At this time, the rolling wheels 213 are blocked and cannot extend outward. When the part where the rolling wheels 213 of the power supply body 1 are located fully enters the well, the electric pulley 303 carries the blocking plate 304 to slide so that the blocking plate 304 leaves the outside where the rolling wheels 213 are located. At this time, the rolling wheels 213 lose the blockage and extend out, thereby preventing the rolling wheels 213 from extending before entering the well, resulting in the outer diameter of the power supply body 1 becoming larger and causing a jamming between the well;

[0036] During the rolling process of the rolling wheel 213, the elastic action of the adapter spring 210 causes the adapter spring 210 to expand and contract as the area changes, thereby causing the penetration rod 211 to expand and contract accordingly. When the penetration rod 211 expands and contracts, the distance between its end and the medium box 207 also changes accordingly. At this time, the laser ranging sensor 215 can measure the distance change in real time, and the change in the well wall can be calculated based on the change in the distance size, thereby obtaining the size change of the inner diameter of the well.

[0037] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
