Description

Technical Field

[0001] The utility model relates to the technical field of mine ore hoisting, in particular to a mine ore hoisting and traction device. Background Art

[0002] Ore refers to the stones containing certain valuable minerals mined from mines. After long-term human mining, only a small part of the ore is distributed on the surface of the mine, and most of the unmined minerals are distributed inside the mine and need to be deeply mined. Currently, after the ore is mined deep underground in the mine, it is loaded into a mine car and directly transported to the ground for processing and refining through a hoisting and traction device.

[0003] When the existing mine ore hoisting and traction equipment hoists and tractions the ore, it is necessary to first put the ore into the mine car, then push the mine car onto the lifting platform, and then start the driving motor to drive the traction rope to pull the lifting platform to lift, hoist the mine car out of the mine shaft, and then push the mine car off the lifting platform to unload the ore.

[0004] However, when the existing mine ore hoisting and traction equipment hoists the ore, it needs to transport the ore through a mine car. When the lifting platform is hoisted by the traction rope, the lifting platform will inevitably shake, which will cause the mine car on the platform to shake, and due to the inertia of the ore stored in it, the shaking amplitude will be even greater. And this kind of shaking increases with the increase of the lifting speed of the platform, thus restricting the working efficiency of the existing device. Content of the Utility Model

[0005] The purpose of this application is to solve the problem that when the existing mine ore hoisting and traction equipment hoists the mine car, the shaking amplitude of the mine car is likely to increase with the increase of the hoisting speed. This application provides a mine ore hoisting and traction device.

[0006] This application specifically adopts the following technical solutions to achieve the above purpose:

[0007] A mine ore hoisting and traction device includes a rising shaft, a body is fixedly connected to the rising shaft, a driving motor is fixedly connected to the body, a rotating roller is arranged on the driving motor, a traction line is fixedly connected to the rotating roller, a lifting block is fixedly connected to the traction line, a rising platform is fixedly connected to the lifting block, a mine car is arranged on the rising platform, and a limiting structure is arranged between the body and the rising shaft.

[0008] By adopting the above technical solution, when using this device to transport ore, first place the ore in the ore cart, then place the ore cart on the ascending platform, and restrict the movement of the ore cart on the ascending platform through the restricting structure. Then start the driving motor to drive the rotating roller to rotate, so that the pulling traction rope drives the ascending platform to lift. While the ascending platform is lifting and lowering, the restricting structure continuously restricts the ore cart, which reduces the movement space of the ore cart during the lifting and lowering process, thereby improving the stability of the ore in the ore cart, making the operator not have to worry about the ore cart tipping over during the lifting and lowering process, and further increasing the rotation speed of the driving motor to lift and lower the ore cart faster, making the device more stable in transporting ore and also improving its transportation efficiency.

[0009] Further, the restricting structure includes a loading groove opened on the ascending platform, an inclined slope is opened on the loading groove, a limiting strip is fixedly connected to the inclined slope, a plurality of universal wheels are fixedly connected to the ore cart, and a pull rod is fixedly connected to the ore cart.

[0010] By adopting the above technical solution, first place the ore in the ore cart, then drive the universal wheels on the ore cart along the inclined slope towards the ascending platform through the pull rod, and limit the movement of the universal wheels through the limiting strip, making the ore cart move up and down on the ascending platform more safely.

[0011] Further, a mounting column is fixedly connected to the ascending platform, a fixed column is fixedly connected to the mounting column, a limiting rod is slidably connected to the fixed column, the limiting rod abuts against the pull rod, an inclined block is fixedly connected to the limiting rod, the inclined block is adapted to the pull rod, a limiting frame is fixedly connected to the ore cart, and the limiting frame is adapted to the limiting rod.

[0012] By adopting the above technical solution, as the ore cart moves towards the top of the loading groove, pull the limiting rod to move it upward along the fixed column, then push the ore cart to the top of the loading groove, and then loosen the limiting rod to make it fall freely downward and insert into the limiting frame on the ore cart to limit the ore cart.

[0013] Further, a pressing spring is sleeved on the fixed column, and both ends of the pressing spring are fixedly connected to the mounting column and the limiting rod respectively.

[0014] By adopting the above technical solution, the pressing spring continuously pushes the limiting rod downward, thereby reducing the possibility of its loosening.

[0015] Further, a sliding column is slidably connected to the limiting rod, a semi-circular limiting groove is opened on the limiting frame, a semi-circular limiting block is fixedly connected to the end of the sliding column, and the semi-circular limiting block is adapted to the semi-circular limiting groove.

[0016] By adopting the above technical solution, the semi-circular limit block moves to be horizontal with the semi-circular limit groove, so that the semi-circular limit block abuts against the semi-circular limit groove, thereby driving the limit between the rising platform and the mine car.

[0017] Furthermore, a limit spring is sleeved on the sliding column, and two ends of the limit spring are fixedly connected to the semi-circular limit block and the limit rod respectively.

[0018] By adopting the above technical solution, the limit spring resets and pushes the semi-circular limit block to move into the semi-circular limit groove, so that the semi-circular limit block abuts against the semi-circular limit groove.

[0019] Furthermore, a main gear is fixedly connected to the machine body, the output end of the driving motor is fixedly connected to the main gear, a driven gear is meshed with the main gear, and the driven gear is fixedly connected to the rotating roller.

[0020] By adopting the above technical solution, when the driving motor rotates, it drives the main gear to rotate, which drives the driven gear to rotate, and makes the two rotating rollers rotate towards each other, thereby driving the four traction ropes to contract simultaneously, lifting the rising platform from the four corners at the same time, making the rising of the rising platform more stable and reducing the shaking of the ore.

[0021] Furthermore, a sliding groove is formed in the rising well, and the sliding groove is adapted to the lifting block.

[0022] By adopting the above technical solution, the cooperation between the sliding groove and the lifting block further enhances the stability of the rising of the rising platform, making it not easy to deviate during rising.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In this application, when the device is used to transport ore, the ore is first placed in the mine car, and then the universal wheels on the mine car are driven by the pull rod to move along the inclined slope to the ascending platform, and the movement of the universal wheels is limited by the limit bar, so that the mine car is safer when going up and down on the ascending platform. As the mine car moves to the top of the upper car slot, the limit rod is pulled to move it upward along the fixed column, and then the mine car is pushed to the top of the upper car slot, and then the limit rod is loosened to allow it to fall freely downward and insert into the limit frame on the mine car. The downward pressure spring continues to push the limit rod downward, thereby reducing the possibility of its loosening. When the limit rod moves to the limit frame, the semicircular limit block moves to be level with the semicircular limit groove. At this time, the limit spring resets and pushes the semicircular limit block to move into the semicircular limit groove, so that the semicircular limit block conflicts with the semicircular limit groove, thereby driving the limit between the lifting platform and the mine car, and then starting the drive motor to drive the rotating roller to rotate, and retracting the traction rope to drive the lifting platform to move upward, so that the mine car is continuously limited during the lifting process, thereby reducing the shaking space of the mine car, making it safer when lifting ore, and allowing the device to increase its lifting speed during use, thereby accelerating the lifting efficiency of the device.

[0025] 2. In this application, when the driving motor rotates, it drives the main gear to rotate, which drives the slave gear to rotate, and allows the two rotating rollers to rotate towards each other, thereby driving the four traction ropes to contract at the same time, and lifting the lifting platform from the four corners at the same time, making the ascent of the lifting platform more stable and reducing the shaking of the ore. The cooperation between the sliding groove and the lifting block further enhances the stability of the ascent of the lifting platform, making it less likely to deviate during the ascent.

[0033] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings.

[0034] The embodiment of this application discloses a mine ore lifting and towing device.

[0035] Referring to Figure 1 and Figure 2 , a mine ore lifting and towing device includes an ascending shaft 3, a machine body 1 fixedly connected to the ascending shaft 3, a driving motor 14 fixedly connected to the machine body 1, a rotating roller 2 arranged on the driving motor 14, a towing line 4 fixedly connected to the rotating roller 2, a lifting block 16 fixedly connected to the towing line 4, an ascending platform 5 fixedly connected to the lifting block 16, a mine car 6 arranged on the ascending platform 5, and a limiting structure arranged between the machine body 1 and the ascending shaft 3.

[0036] When using this device to transport ore, first place the ore in the mine car 6, then place the mine car 6 on the ascending platform 5, and limit the movement of the mine car 6 on the ascending platform 5 through the limiting structure. Then start the driving motor 14 to drive the rotating roller 2 to rotate, so as to drive the towing rope to lift the ascending platform 5. While the ascending platform 5 is lifting and lowering, the limiting structure continuously limits the mine car 6, which reduces the movement space of the mine car 6 during the lifting and lowering process, thereby improving the stability of the ore in the mine car 6, making the operator not have to worry about the mine car 6 tipping over during the lifting and lowering process, and then increasing the rotational speed of the driving motor 14 to lift and lower the mine car 6 faster, making the device more stable in transporting ore and also improving its transportation efficiency.

[0037] Referring to Figure 2 and Figure 3 , Figure 4 , Figure 5, the limiting structure includes an on-vehicle groove opened on the ascending platform 5. An inclined slope 7 is opened on the on-vehicle groove, and a limiting bar 8 is fixedly connected to the inclined slope 7. A number of universal wheels 15 are fixedly connected to the ore car 6, and a pull rod 12 is fixedly connected to the ore car 6. An installation column 10 is fixedly connected to the ascending platform 5, a fixed column 11 is fixedly connected to the installation column 10, a limiting rod 9 is slidably connected to the fixed column 11, the limiting rod 9 abuts against the pull rod 12, an inclined block 13 is fixedly connected to the limiting rod 9, the inclined block 13 is adapted to the pull rod 12, a limiting frame 20 is fixedly connected to the ore car 6, and the limiting frame 20 is adapted to the limiting rod 9. A pressing spring 19 is sleeved on the fixed column 11, and both ends of the pressing spring 19 are fixedly connected to the installation column 10 and the limiting rod 9 respectively. A sliding column 21 is slidably connected to the limiting rod 9, a semi-circular limiting groove is opened on the limiting frame 20, a semi-circular limiting block 23 is fixedly connected to the end of the sliding column 21, and the semi-circular limiting block 23 is adapted to the semi-circular limiting groove. A limiting spring 22 is sleeved on the sliding column 21, and both ends of the limiting spring 22 are fixedly connected to the semi-circular limiting block 23 and the limiting rod 9 respectively.

[0038] When using this device to transport ores, first place the ores in the ore car 6, then drive the universal wheels 15 on the ore car 6 along the inclined slope 7 towards the ascending platform 5 through the pull rod 12, and limit the movement of the universal wheels 15 through the limiting bar 8, making the ore car 6 move more safely up and down on the ascending platform 5. As the ore car 6 moves towards the top of the on-vehicle groove, pull the limiting rod 9 to move it upward along the fixed column 11, then push the ore car 6 to the top of the on-vehicle groove, and then loosen the limiting rod 9 to make it fall freely downward and insert into the limiting frame 20 on the ore car 6. And the continuous pushing of the pressing spring 19 makes the limiting rod 9 move downward, thus reducing the possibility of its loosening. When the limiting rod 9 moves into the limiting frame 20, the semi-circular limiting block 23 moves to be horizontal with the semi-circular limiting groove. At this time, the limiting spring 22 resets and pushes the semi-circular limiting block 23 to move into the semi-circular limiting groove, making the semi-circular limiting block 23 abut against the semi-circular limiting groove, thereby driving the limiting between the ascending platform 5 and the ore car 6. Then start the driving motor 14 to drive the rotating roller 2 to rotate, contract the traction rope to drive the ascending platform 5 to move upward, making the ore car 6 continuously be limited during the lifting process, thus reducing the shaking space of the ore car 6, making it safer to lift the ores, enabling the device to increase its lifting speed during use, and further accelerating the lifting efficiency of the device.

[0039] Refer to Figure 2 And Figure 3 , a main gear 18 is fixedly connected to the body 1, the output end of the driving motor 14 is fixedly connected to the main gear 18, a driven gear 17 is meshed with the main gear 18, and the driven gear 17 is fixedly connected to the rotating roller 2. A sliding groove is opened on the ascending shaft 3, and the sliding groove is adapted to the lifting block 16.

[0040] When the driving motor 14 rotates, it drives the main gear 18 to rotate, which drives the slave gear 17 to rotate, and makes the two rotating rollers 2 rotate towards each other, thereby driving the four traction ropes to contract at the same time, and lifting the lifting platform 5 from the four corners at the same time, making the rising of the lifting platform 5 more stable and reducing the shaking of the ore. The cooperation between the sliding groove and the lifting block 16 further enhances the stability of the rising platform 5, making it less likely to deviate during the rise.

[0041] Working principle: When the device is used to transport ore, the ore is first placed in the mine car 6, and then the universal wheel 15 on the mine car 6 is driven by the pull rod 12 to move along the inclined slope 7 to the rising platform 5, and the movement of the universal wheel 15 is limited by the limit bar 8, so that the mine car 6 is safer to move up and down on the rising platform 5. As the mine car 6 moves to the top of the upper car slot, the limit rod 9 is pulled to move it upward along the fixed column 11, and then the mine car 6 is pushed to the top of the upper car slot, and then the limit rod 9 is loosened to make it fall freely downward and inserted into the limit frame 20 on the mine car 6, and the downward pressure spring 19 continues to push the limit rod 9 downward, thereby reducing its loosening. Possibly, when the limiting rod 9 moves into the limiting frame 20, the semicircular limiting block 23 moves to be level with the semicircular limiting groove. At this time, the limiting spring 22 resets and pushes the semicircular limiting block 23 to move into the semicircular limiting groove, so that the semicircular limiting block 23 conflicts with the semicircular limiting groove, thereby driving the limit between the lifting platform 5 and the mine car 6, and then starting the driving motor 14 to drive the rotating roller 2 to rotate, and the traction rope is retracted to drive the lifting platform 5 to move upward, so that the mine car 6 is continuously limited during the lifting process, thereby reducing the swaying space of the mine car 6, making it safer when lifting ore, and allowing the device to increase its lifting speed during use, thereby accelerating the lifting efficiency of the device;

[0042] When the driving motor 14 rotates, it drives the main gear 18 to rotate, which drives the slave gear 17 to rotate, and makes the two rotating rollers 2 rotate towards each other, thereby driving the four traction ropes to contract at the same time, and lifting the lifting platform 5 from the four corners at the same time, making the rising of the lifting platform 5 more stable and reducing the shaking of the ore. The cooperation between the sliding groove and the lifting block 16 further enhances the stability of the rising platform 5, making it less likely to deviate during the rise.
