Description

Technical Field

[0001] The invention relates to the technical field of safety protection devices, and in particular to a material-falling protection device for a mine skip hoisting system. Background Art

[0002] The ore, coal and other minerals in the mine are mostly lifted by vertical shaft skips. The skip is a container that directly loads useful minerals, stone or gangue. It is generally divided into two types: for inclined shafts and for vertical shafts. According to different unloading methods, it can be divided into bottom unloading type and flip type for vertical shafts. In the field of mining technology, the flip type skip of vertical shaft is the most commonly used. The skip of this structure is generally provided with an articulated shaft at the bottom and is lifted and lowered by wire ropes. When it reaches the designated unloading position, the limit component is unlocked, and the skip uses its own weight to flip around the articulated shaft to complete the unloading.

[0003] Ore spillage is inevitable during the process of loading and unloading ore from the skip. Generally, mines adopt the method of regular cleaning. Due to the harsh environment below the skip and the cleaning chamber, it is difficult for personnel to check. Due to the constraints of conditions such as water splashing in the shaft, ore spillage during loading and unloading, and mine fog, modern observation equipment cannot be used. Once a large amount of shaking occurs during the skip lifting process, the skip limit components will be unlocked, and even the wire rope will break after long-term use, causing the skip to tilt inside the mine. It is very easy for a large amount of material to spill to the bottom of the mine. When the material at the bottom of the mine accumulates to a certain amount, it will seriously affect the safety of the lifting system. Summary of the invention

[0010] Optionally, the interiors of the multiple round blocks are hollow, and the inner walls of the multiple round blocks are provided with multiple oil outlets, and the tops of the multiple round blocks are equipped with connecting ends for connecting to external preset oil delivery equipment.

[0012] Optionally, the protection mechanism includes a second groove and two second guide grooves opened on the top of the two first movable plates, a screw rod is rotatably installed inside the two second grooves, a second movable block is threadedly installed on the outer walls of the two screw rods, a second guide block is installed inside the two second guide grooves, a second movable plate is respectively installed on the top of the two second movable blocks and the two second guide blocks, and a notch is opened at the ends away from each other of the two second movable plates.

[0013] Optionally, rotating rods are rotatably installed on the outer walls of both sides of the shell, the widths of the two rotating rods are adapted to the widths of the two notches, the top ends of the two rotating rods are connected to the outer wall of the shell through connecting springs, and the bottom ends of the two rotating rods are installed with limit blocks.

[0014] Optionally, both side outer walls of the shell are provided with through grooves for the insertion of limit blocks, and both side outer walls of the bucket body are provided with limit grooves matched with the limit blocks.

Two clamping plates for clamping and fixing the first steel wire rope are threadedly installed on the outer walls of the two second double-headed screws.

[0016] The beneficial effects of the present invention are:

[0017] 1. In the present invention, during the process of the shell and the skip body transporting ore, the protective mechanism is set up to ensure the stability of the shell and the skip body when an unexpected situation occurs in the lifting system, and has a limiting and fixing effect on the shell and the skip body, thereby avoiding the unexpected situation that a large amount of ore inside the skip body falls downward, thereby improving the safety and stability of the skip body when in use.

[0018] 2. In the invention, during normal use of the shell and the skip body, after the ore at the bottom of the mine is transported upward to the designated position, the skip body rotates downward inside the shell, and in the process of pouring out the ore inside it, the sliding blocks on the outer walls of both sides of the skip body will slide downward together inside the corresponding arc-shaped grooves. In the process of sliding downward, the two sliding blocks will drive the corresponding buffer springs to be squeezed, so that when the two buffer springs are deformed by being squeezed, they can have a buffering effect on the gravity generated during the downward rotation of the skip body, thereby preventing the skip body from rotating downward at a fast speed, causing the skip body to shake significantly during the pouring process, and causing some ore to fail to fall accurately at the designated position, thereby improving the safety of the skip body during the pouring process.

[0019] 3. In the present invention, after the first plurality of steel wire ropes have been used for a period of time, impurities will inevitably adhere to their outer walls. After the shell and the skip body are moved to the top of the mine, the mounting plate is located at the top of the shell, and the two second steel wire ropes are reeled in with the help of traction equipment, which has the effect of pulling and limiting the mounting plate. Then the lifting equipment is controlled to drive the first plurality of steel wire ropes to extend downward, so that the shell and the skip body move downward to the bottom of the mine. At this time, there is no need to load ore into the interior of the skip body, and the first plurality of steel wire ropes are directly driven to be slowly reeled upward by controlling the lifting equipment. In the process of continuous upward movement of the first plurality of steel wire ropes, the steel brush located inside the round block rubs against the surface of the first steel wire rope, and automatically cleans the impurities attached to the surface of the first steel wire rope, thereby avoiding the long-term accumulation of impurities and the adverse effect on the use of the first steel wire rope.

[0020] 4. In the invention, after the multiple first steel wire ropes move upward to the top of the mine, the preset oil storage tank can be controlled to transport the lubricating oil to the inside of the multiple round blocks, and discharge it to the surface of the corresponding first steel wire ropes through multiple oil outlets. As the lifting equipment drives the multiple first steel wire ropes to extend downward again, the shell and the bucket body move slowly downward inside the mine. During the process of the multiple first steel wire ropes extending downward inside the corresponding round blocks, the lubricating oil can be evenly applied to the surface of the multiple first steel wire ropes, thereby achieving the effect of automatically lubricating the surface of the multiple first steel wire ropes, which is convenient for extending the service life of the multiple first steel wire ropes, indirectly protecting the entire lifting system, and reducing the phenomenon of ore falling downward.

[0038] As a technical optimization solution of the present invention, a first groove 18 and two first guide grooves 19 are provided on the top of the mounting plate 4, and a first double-headed screw 23 and two first guide blocks 25 are installed inside the first groove 18 and the two first guide grooves 19 respectively.

[0039] As a technical optimization solution of the present invention, the protection mechanism includes a second groove 26 and two second guide grooves 28 opened at the top of the two first movable plates 14, the inside of the two second grooves 26 are both rotatably installed with screw rods 27, the outer walls of the two screw rods 27 are both threadedly installed with second moving blocks 29, the inside of the two second guide grooves 28 are both installed with second guide blocks 30, the tops of the two second moving blocks 29 and the two second guide blocks 30 are respectively installed with second movable plates 15, and the ends of the two second movable plates 15 that are away from each other are both provided with notches 31. Second drive motors are preset inside the two first movable plates 14, and the output ends of the two second drive motors are respectively connected to one end of the corresponding screw rods 27, so as to drive the two screw rods 27 to rotate inside the corresponding second grooves 26, and drive the second movable blocks 29 and the second movable plates 15 on their outer walls to move and adjust synchronously.

[0040] As a technical optimization solution of the present invention, rotating rods 5 are rotatably installed on the outer walls of both sides of the housing 1, and the width of the two rotating rods 5 is adapted to the width of the two notches 31. The top ends of the two rotating rods 5 are connected to the outer wall of the housing 1 through the connecting springs 6, and the bottom ends of the two rotating rods 5 are installed with limit blocks 7. When the two second movable plates 15 move in the direction away from each other, the notches 31 inside them can be abutted and adapted with the top ends of the corresponding rotating rods 5, and the rotating rods 5 are pushed to rotate. After the two second movable plates 15 move and reset, the rotating rods 5 can be elastically reset with the help of the connecting springs 6.

[0041] As a technical optimization solution of the present invention, both sides of the outer wall of the shell 1 are provided with through grooves 10 for the limit blocks 7 to be inserted, and both sides of the outer wall of the bucket body 2 are provided with limit grooves 11 adapted to the limit blocks 7. When the two rotating rods 5 rotate, the limit blocks 7 at the bottom thereof are driven to pass through the through grooves 10 and be engaged and adapted with the limit grooves 11 on the outer wall of the bucket body 2, so as to limit and fix the position of the bucket body 2 inside the shell 1, and prevent the bucket body 2 from rotating inside the shell 1.

[0042] As a technical optimization solution of the present invention, two fixing frames 32 are installed on the outer wall of the side away from the two first movable plates 14, and the second double-headed screws 34 are rotatably installed inside the two fixing frames 32, and the outer walls of the two second double-headed screws 34 are threadedly installed with two clamping plates 33 for clamping and fixing the first steel wire rope 3. A third driving motor is preset on the outer wall of one side of the multiple fixing frames 32, and the output ends of the multiple third driving motors are respectively connected to one end of the corresponding second double-headed screws 34, which can drive the multiple second double-headed screws 34 to rotate inside the corresponding fixing frames 32, and drive the two clamping plates 33 to move and adjust in the direction of approaching or moving away from each other.

[0043] In the present invention, when the user uses the device, the lifting equipment arranged at the top of the mine can drive the multiple first steel wires 3 to reel upward or extend downward, driving the shell 1 and the bucket body 2 to move up and down synchronously inside the mine, and the traction equipment arranged at the top of the mine can drive the two second steel wires 8 to reel upward or extend downward, driving the mounting plate 4 and the multiple components arranged on the top of the shell 1 to move up and down together on the top of the shell 1. When the shell 1 and the bucket body 2 are located at the bottom of the mine, the traction equipment will drive the two second steel wires 8 to reel upward, pulling the mounting plate 4. The multiple components arranged on the top of the shell body 1 move upward together, so that the opening on the top of the shell body 1 is exposed, and the relevant loading equipment inside the mine can load the ore into the interior of the skip body 2 through the opening on the top of the shell body 1. As the lifting equipment drives the multiple first steel ropes 3 to be wound, the shell body 1 and the skip body 2 can be pulled upward from the bottom of the mine to the top of the mine, until the shell body 1 moves to the specified position, the skip body 2 can be rotated downward inside the shell body 1 to pour out the ore filled inside it, thereby completing the lifting and transportation of the ore.

[0044] In the process of the shell body 1 and the skip body 2 moving upward from the bottom of the mine, the traction equipment can be controlled to drive the two second steel wire ropes 8 to extend, so that the mounting plate 4 moves downward to abut against the top of the shell body 1, and the first double-headed screw 23 is controlled to drive the two first moving blocks 24 to move in a direction away from each other, and drive the two first moving plates 14 to move in a direction away from each other on the top of the mounting plate 4, until the two first moving plates 14 are moved away from the two fixing frames 32 arranged on the outer wall on one side to abut against the corresponding first steel wire ropes 3, and then the second double-headed screws 34 inside the multiple fixing frames 32 are controlled to rotate, driving the two clamping plates 33 to clamp and fix the corresponding first steel wire ropes 3, such as the shell body 1 and the skip body. When the body 2 is moving upward, one or more of the first steel wire ropes 3 break. Since the clamping plates 33 arranged on the outer walls of the two first movable plates 14 are far away from each other and are respectively clamped and fixed with the multiple first steel wire ropes 3, after one or more of the first steel wire ropes 3 break, the two second steel wire ropes 8 can replace the first steel wire ropes 3 to pull and limit the shell body 1 and the skip body 2, so that the shell body 1 and the skip body 2 will only have a certain degree of bumps, and there will be no accidental situation that the shell body 1 and the skip body 2 fall directly downward, or the skip body 2 tilts, and the ore inside it is poured downward into the mine, thereby achieving a better protection effect on the shell body 1 and the skip body 2.

[0045] When the shell 1 and the skip body 2 are shaken, the relevant alarm arranged inside the shell 1 will transmit data to the controller, and the controller will control the two screw rods 27 to rotate together, driving the two second moving blocks 29 to move quickly in the corresponding second grooves 26 in the directions away from each other, so that the two second moving plates 15 move in the directions away from each other on the top of the mounting plate 4 until the ends of the two second moving plates 15 that are away from each other are tightly abutted against the inner wall of the mine, so that the shell 1 and the skip body 2 that are shaken at this time can be limited and fixed, thereby improving the safety of the shell 1 and the skip body 2 when in use.

[0046] When the two second movable plates 15 move in the direction away from each other, the ends of the two second movable plates 15 that are away from each other move a certain distance on the top of the mounting plate 4, so that the inner wall of the notch 31 set at the ends of the two second movable plates 15 that are away from each other pushes the top of the two rotating rods 5, driving the two rotating rods 5 to rotate on the outer walls on both sides of the shell 1, and driving the two connecting springs 6 to be in a stretched state. The limit blocks 7 set at the bottom ends of the two rotating rods 5 pass through the corresponding through grooves 10 and are inserted into the limit grooves 11 opened on the outer walls on both sides of the bucket body 2, so as to achieve the effect of limiting and fixing the bucket body 2, avoiding the shell 1 from experiencing a large degree of bumping, so that the bucket body 2 rotates downward inside the shell 1, and the ore filled inside is poured downward to the bottom of the mine, thereby further improving the stability of the bucket body 2 during use.

[0047] After one or more of the first steel wire ropes 3 are broken, they need to be replaced in time. When a new first steel wire rope 3 needs to be installed, the shell 1 and the bucket body 2 are placed at the bottom of the mine, and the clamping limit state of the first steel wire rope 3 after the breakage of the top of the shell 1 by the multiple groups of clamps 33 is released. Then the traction equipment is controlled to drive the two second steel wire ropes 8 to move upward to the top of the mine. After the staff passes one or more new first steel wire ropes 3 downward through the inside of the corresponding round block 17, the new first steel wire rope 3 inserted downward from the top of the round block 17 is clamped and fixed with the help of two groups of clamps 33 set on the outer wall of one side of the two first movable plates 14. At this time, with the traction equipment The equipment drives the two second steel wire ropes 8 to extend downward, so that the mounting plate 4 moves slowly downward inside the mine, and at the same time controls the lifting equipment to drive one or more new first steel wire ropes 3 to extend slowly downward together, until the mounting plate 4 moves downward to the bottom of the mine, and the staff can reinstall the first steel wires 3 at the corresponding positions inside one or more round blocks 17 at the corresponding positions on the top of the shell 1, so that at this time the mounting plate 4 cooperates with the two second steel wire ropes 8 to guide the installation of the new first steel wire rope 3, ensuring the accurate installation position of the new first steel wire rope 3, avoiding the problem of multiple first steel wire ropes 3 being entangled with each other, affecting the installation, and improving the applicability of components such as the mounting plate 4.

[0048] During normal use of the shell 1 and the skip body 2, after the ore at the bottom of the mine is transported upward to the designated position, the skip body 2 rotates downward inside the shell 1. In the process of pouring out the ore inside, the sliding blocks 12 on the outer walls of the two sides of the skip body 2 will slide downward together inside the corresponding arc grooves 9. The two sliding blocks 12 will drive the corresponding buffer springs 13 to be squeezed during the downward sliding process, so that when the two buffer springs 13 are deformed by being squeezed, they can have a buffering effect on the gravity generated during the downward rotation of the skip body 2, thereby avoiding the skip body 2 from rotating downward at a fast speed, causing the skip body 2 to shake significantly during the pouring process, and causing some ores to fail to fall accurately at the designated position, thereby improving the safety of the skip body 2 during the pouring process.

[0049] After the multiple first steel wire ropes 3 have been used for a period of time, impurities will inevitably adhere to their outer walls. After the shell 1 and the skip body 2 are moved to the top of the mine, the mounting plate 4 is located at the top of the shell 1. The two second steel wire ropes 8 are reeled in with the help of traction equipment, which has the effect of pulling and limiting the mounting plate 4. Then the lifting equipment is controlled to drive the multiple first steel wire ropes 3 to extend downward, so that the shell 1 and the skip body 2 move downward to the bottom of the mine. At this time, there is no need to load ore into the interior of the skip body 2. The multiple first steel wire ropes 3 are directly driven to slowly reel upward by controlling the lifting equipment. In the process of continuous upward movement of the multiple first steel wire ropes 3, the wire brush 21 located inside the round block 17 can automatically clean the impurities attached to the surface of the first steel wire rope 3 during the friction contact with the surface of the first steel wire rope 3, so as to avoid the long-term accumulation of impurities and the adverse effect on the use of the first steel wire rope 3.

[0050] After the multiple first steel wire ropes 3 move upward to the top of the mine, the preset oil storage tank can be controlled to transport the lubricating oil to the inside of the multiple round blocks 17, and discharge it to the surface of the corresponding first steel wire ropes 3 through the multiple oil outlets 20. As the lifting equipment drives the multiple first steel wire ropes 3 to extend downward again, the shell 1 and the bucket body 2 move slowly downward inside the mine. During the process of the multiple first steel wire ropes 3 extending downward inside the corresponding round blocks 17, the lubricating oil can be evenly applied to the surface of the multiple first steel wire ropes 3, thereby achieving the effect of automatically lubricating the surface of the multiple first steel wire ropes 3, which is convenient for extending the service life of the multiple first steel wire ropes 3, indirectly protecting the entire lifting system, and reducing the phenomenon of ore falling downward.
