[0025] This embodiment provides a mine hoisting device, such as Figure 1-Figure 6 As shown, it includes a support frame 1, which includes a support column 11 and a transverse axis 12. The transverse axis 12 is installed at the upper end of the support column 11, and two pulleys 121 are arranged on the transverse axis 12. A traction device 2 is arranged on one side of the support frame 1, and the traction device 2 is used for retracting and releasing a steel wire rope 3. The steel wire rope 3 passes around the pulley 121, and one end of the steel wire rope 3 is connected to a lifting plate 4, and the other end of the steel wire rope 3 is connected to the traction device 2. A slide groove 41 is opened at the corner of the lifting plate 4, and the slide groove 41 is slidably connected to the side wall of the support column 11 through a sliding assembly 5. A lifting cage 42 is arranged on the upper end surface of the lifting plate 4.

[0026] A support column 11 is provided at the lower part of the support frame 1, and the support column 11 extends into the underground mine. A horizontal axis 12 is installed at the upper end of the support frame 1, and two pulleys 121 are provided on the horizontal axis 12. The wire rope 3 passes over the pulley 121, and one end is connected to the lifting plate 4, and the other end of the wire rope 3 is connected to the traction device 2. In actual situations, the space around the mine is limited, and the traction device 2 cannot be arranged. It is necessary to set the traction device 2 on the side of the mine. The pulley 121 is used to change the traction direction of the side traction device 2, so that the traction direction of the wire rope 3 is perpendicular to the lifting plate 4, so that the lifting plate 4 keeps moving in the vertical direction, which is beneficial to improve the stability when the lifting plate 4 is pulled. A slide groove 41 is opened at the corner of the lifting plate 4. The slide groove 41 is slidably connected to the side wall of the support column 11 through a sliding component 5. The side of the support column 11 plays a role The role of limiting is that when the lifting platform 4 rises vertically, the side of the support column 11 will support and stabilize the lifting platform 4 in the horizontal plane, avoiding the lifting platform 4 from shaking in the horizontal plane when it is lifted or lowered, and further improving the stability of the lifting platform 4 when it moves. In addition, the two pulleys 121 pass through the two steel ropes 3 for traction, which can provide better balance and support for the lifting platform 4 in the vertical direction, reduce the shaking and swaying of the lifting platform 4, thereby improving the stability of the lifting platform 4, and then improving the stability of the lifting cage 42 set on the upper end surface of the lifting platform 4. The lifting platform 4 is set below the lifting cage 42, which can play a protective role. If the ore transported in the lifting cage 42 falls, the ore will first fall onto the surface of the lifting platform 4, avoiding the ore falling into the mine and causing damage to the construction personnel or equipment.

[0027] In one embodiment of the present application, Figure 4 As shown, the sliding assembly 5 includes two fixed blocks 51 , a roller shaft 52 is disposed between the two fixed blocks 51 , and the roller shaft 52 is rotatably connected to the fixed blocks 51 .

[0028] The fixed block 51 is used for inserting and installing the roller shaft 52, and the roller shaft 52 is rotatably connected to the fixed block 51. When the lifting plate 4 moves up and down, the roller shaft 52 contacts the side of the support column 11, and the roller shaft 52 rotates, thereby realizing the sliding connection between the side wall of the support column 11 and the slide groove 41. The rolling contact between the roller shaft 52 and the side of the support column 11 is beneficial to reducing the friction resistance between the lifting plate 4 and the support column 11 when it moves in the vertical direction.

[0029] In one embodiment of the present application, Figure 5 As shown, the traction device 2 includes a motor 21 , which is drivingly connected to a rotating shaft 22 , and two rotating disks 221 are connected to the rotating shaft 22 , and the rotating disks 221 are connected to the steel wire rope 3 .

[0030] The output shaft of the motor 21 drives the rotating shaft 22 to rotate. Two turntables 221 are connected to the rotating shaft 22. Because the two turntables 221 are fixed on the same rotating shaft 22, when the rotating shaft 22 rotates, the two turntables 221 rotate at the same speed. The turntables 221 are connected to the wire rope 3, so that the two wire ropes 3 are extended or contracted at the same speed, so that the two wire ropes 3 can achieve synchronization, which is beneficial to improving the stability of the wire rope 3 being pulled up.

[0031] In one embodiment of the present application, Figure 5 As shown, the motor 21 is transmission-connected to the rotating shaft 22 via a reducer 23 .

[0032] The reducer 23 can smoothly convert the high-speed rotation of the motor 21 into a low-speed, high-torque output, which is used to reduce the vibration and impact of the motor 21 during operation, thereby improving the operating stability and reliability of the traction device 2, which is beneficial to improving the stability of the wire rope 3 pulling the lifting plate 4.

[0033] In one embodiment of the present application, Figure 3 As shown, the lifting cage 42 includes a storage bin 421 , and a bin door 422 is provided on a side of the storage bin 421 .

[0034] Opening the door 422 on the side of the storage bin 421 and placing the mineral material in the storage bin 421 is more convenient and labor-saving than placing the mineral material through the open opening on the top of the storage bin 421, which is beneficial to improving the efficiency of mineral material transportation.

[0035] In one embodiment of the present application, Figure 6 As shown, a protective cover 24 is provided outside the traction device 2 .

[0036] The protective cover 24 can prevent external objects such as rain, rocks and debris from accidentally entering the traction device 2, reduce the risk of interference and damage to the normal operation of the motor 21, and help improve the stability of the operation of the traction device 2. Preferably, the side of the protective cover 24 is provided with heat dissipation holes to ensure normal heat dissipation of the motor 21 of the traction device 2.

[0037] In one embodiment of the present application, Figure 5 and Figure 6 As shown, a supporting diagonal rod 13 is connected to the supporting column 11 close to the traction device 2 .

[0038] The supporting diagonal rod 13 is used to provide additional supporting force for the supporting column 11 , and disperse the horizontal component of the traction wire rope 3 of the traction device 2 , which is beneficial to improving the stability of the supporting frame 1 .

[0039] In the actual use of this application: a support column 11 is provided at the lower part of the support frame 1, and the support column 11 extends into the underground mine. A horizontal axis 12 is installed at the upper end of the support frame 1, and two pulleys 121 are provided on the horizontal axis 12. The steel wire rope 3 passes through the pulley 121, and one end is connected to the lifting plate 4. The other end of the steel wire rope 3 is connected to the traction device 2. The pulley 121 is used to change the traction direction of the lateral traction device 2, so that the traction direction of the steel wire rope 3 is perpendicular to the lifting plate 4, so as to improve the stability when traction is applied to the lifting plate 4. A slide groove 41 is provided at the corner of the lifting plate 4. The slide groove 41 is slidably connected to the side wall of the support column 11 through the sliding assembly 5, and the side of the support column 11 plays a role of limiting. When the lifting platform 4 rises vertically, the side of the support column 11 will support and stabilize the lifting platform 4 in the horizontal plane. The two pulleys 121 pass through the two steel ropes 3 for traction, which can provide better balance and support for the lifting platform 4 in the vertical direction, reduce the shaking and swaying of the lifting platform 4, thereby improving the stability of the lifting platform 4, and further improving the stability of the lifting cage 42 set on the upper end surface of the lifting platform 4.
