[0014] Compared with the prior art, the present application has the following beneficial effects:

[0015] 1. In view of the fact that the existing buffer unloading components at the bottom of the elevator are vulnerable to external invasion of the lifting channel and affect operation due to lack of active protection structure, the present application triggers the lead screw in the guide groove at the top of the buffer column when the material bearing bin is lifted, and synchronously lifts the buffer platform through the scissors lever, and when reaching the limit position, the bottom seal cover of the buffer platform automatically closes the opening two, forming a protective barrier to actively block the path of external objects, solving the problem of fixed protection structure and delayed protection timing in the prior art, and effectively ensuring the continuous and stable operation of the elevator.

[0016] 2. In view of the problem of inconvenient material taking or insufficient protection caused by the fixed position of the buffer structure in the prior art, the present application reverses the lead screw when the material bearing bin is lowered, causing the buffer platform to descend synchronously and open the opening two, ensuring accurate positioning of the material bearing bin and convenient material taking, and more importantly, if an accidental fall occurs, the lifted buffer platform has sealed the bottom space of the lifting channel, forming a closed area at the bottom of the material bearing bin, and significantly slowing down the falling speed through air cushion; at the same time, the closure of the opening two can prevent the material from splashing out, solving the pain point of secondary injury caused by material overflow after falling impact in the prior art.

[0017] 3. In view of the problem of limited damping effect due to the dependence on single buffer structure in the prior art, the present application innovatively adopts a multi-stage buffer design of "top spring + buffer bin + buffer sleeve": when the material bearing bin hits the buffer platform, the multiple top springs on the buffer column first buffer and dampen the impact; the buffer bin between the buffer platform and the supporting plate further absorbs the impact; and the buffer sleeve at the bottom of the supporting plate finally dissipates the remaining impact force. At the same time, the cooperation of the connecting head at the top of the buffer platform and the clamping interface at the bottom of the material bearing bin can instantly lock the bearing bin, avoiding secondary damage caused by rebound after impact, and realizing maximum dissipation of impact force through multi-process cooperation, far exceeding the single buffering effect of the prior art and better adapting to actual working conditions.

[0018] 4. In view of the problem of lack of quick response locking mechanism when falling from a high place in the prior art, the present application designs an innovative emergency protection structure: when the material bearing bin falls from a high place, the counterweight block moves relatively straight due to inertia, and the top needle of the counterweight block inserts into the seal trigger to open the gas tank, the compressed gas drives the impeller to rotate through the through hole at the bottom of the straight cylinder, and then drives the fixed column to rise through screw transmission, expands the side column to the two sides, and pushes the clamping plate to engage with the inner side wall plate of the lifting channel, quickly completes the locking, effectively prevents the bearing bin from continuing to fall, and through the relative displacement of the clamping plate and the sliding plate, more sliding blocks are leaked when the clamping plate expands outward; at the same time, the gas discharged from the gas tank enters the sliding plate through the connecting pipe, pushes out the exposed sliding blocks, and forms a mechanical limit to prevent the clamping plate from retracting, which ensures the stable engagement of the clamping plate and the side plate, solves the problem of easy loosening of the locking state in the prior art, and guarantees the persistence of the locking effect.

[0019] 5、In view of the problem of slow response of the lower section falling protection mechanism in the prior art, the application constructs a full-scene protection system: when the material bearing bin falls in the lower section of the lifting channel, the buffer table is impacted and compressed to compress the buffer bin, the gas in the buffer bin is guided into the straight cylinder through the material bearing bin bottom hole, and the emergency locking is triggered, which is complementary to the high falling protection, realizes the full-range emergency protection under different heights and different working conditions, and significantly improves the safety redundancy of the equipment.

In the working process of the material carrying bin 107, when the material carrying bin 107 starts to lift, the distance sensor at the top of the buffer column 124 sends a signal to start the lead screw in the guide groove 130, which can drive the shear bar 128 to work through the work of the lead screw through the sliding seat 129, so that the shear bar 128 can lift the supporting plate 134 and the buffer platform 108, so that the buffer platform 108 can be lifted with the material carrying bin 107. When the buffer platform 108 is lifted to the limit, the seal cover 116 fixed at the bottom of the buffer platform 108 can seal the through opening two 106, so that the seal cover 116 and the bottom bin 109 can realize the protection work of the bottom buffer unloading part of the hoist, avoid foreign matters entering the hoist channel 101, and affect the work of the hoist. When the material carrying bin 107 is lifted to the top, it will reach the through opening one 102, which is convenient for people to transfer materials. In the process of descending the material carrying bin 107, when the material carrying bin 107 descends to the detection range of the distance sensor at the top of the buffer column 124, the bottom lead screw will work again, so that the buffer platform 108 will descend with the material carrying bin 107, and the through opening two 106 will leak out, so that the material carrying bin 107 can descend to the through opening two 106, which is convenient for people to take materials.

[0037] The bottom of the lifting channel 101 is fixedly connected with a bottom bin 109, the inside of the bottom bin 109 is provided with a buffer table 108, the bottom of the buffer table 108 is fixedly connected with a buffer bin 127, the bottom of the buffer bin 127 is fixedly connected with a supporting plate 134, the top end of the buffer table 108 is provided with a connecting head 126, the bottom end of the supporting plate 134 is provided with a plurality of buffer sleeves 132, the bottom of the buffer sleeves 132 is installed in the bottom of the bottom bin 109, the bottom of the supporting plate 134 is provided with a pair of scissors rods 128, the upper and lower parts of the scissors rods 128 are slidably connected with guide rails 131, the guide rails 131 are fixedly connected with the bottom of the supporting plate 134 and the bottom of the bottom bin 109, the corners of the buffer table 108 and the supporting plate 134 are penetrated by buffer columns 124, the buffer columns 124 are slidably connected with the buffer table 108 and the supporting plate 134, the top end of the buffer columns 124 is provided with a distance sensor, the buffer columns 124 are provided with a plurality of top springs 123, the top springs 123 are arranged on the upper part of the buffer table 108 and the supporting plate 134, the bottom of the scissors rods 128 is fixedly connected with sliding seats 129, the bottom of the bottom bin 109 is provided with symmetrical guide grooves 130, the bottom of the sliding seats 129 is slidably connected in the guide grooves 130, the bottom of the sliding seats 129 is provided with lead screws, the lead screws are installed in the inside of the guide grooves 130, the outside of the connecting head 126 is provided with a plurality of clamping blocks, the top of the buffer table 108 is provided with a material bearing bin 107, the bottom end of the material bearing bin 107 is provided with a connecting seat, the bottom end of the connecting seat is provided with a connecting port, the connecting port is used for cooperating with the connecting head 126, the inside of the bottom plate of the material bearing bin 107 is provided with a plurality of channels, the inside of the lifting channel 101 is fixedly connected with side plates 138, the side plates 138 are provided with uniformly distributed clamping strips 137 near the material bearing bin 107;

[0038] Further, in specific implementation, when the material carrying bin 107 falls accidentally during work, the bottom space of the lifting channel 101 is blocked by the lifting of the buffer platform 108, so that the bottom of the material carrying bin 107 is a closed space, so that the material carrying bin 107 and the lifting channel 101 form an air buffer, so as to effectively slow down the falling speed of the material carrying bin 107 and reduce the impact. At the same time, the buffer platform 108 can close the through hole two 106, so as to avoid the internal material of the material carrying bin 107 flying out through the through hole two 106 to cause additional damage after the material carrying bin 107 falls at high speed. When the material carrying bin 107 impacts on the buffer platform 108, the multiple sets of top springs 123 sleeved on the buffer columns 124 can fully buffer the impact, and the connecting head 126 at the top of the buffer platform 108 can be in contact with the connecting port at the bottom of the material carrying bin 107, so that the material carrying bin 107 can be locked by the buffer platform 108, so as to avoid the material carrying bin 107 from bouncing up again after impact and causing further damage. At the same time, the buffer space 127 between the buffer platform 108 and the supporting plate 134 can provide buffer for the buffer platform 108, reduce the impact of the material carrying bin 107 on the buffer platform 108, and further buffer the impact transmitted by the supporting plate 134 through the buffer sleeve 132 at the bottom of the supporting plate 134. Through multiple buffering and force-dissipating processes, the impact force on the material carrying bin 107 can be maximally dissipated and buffered, which is beneficial to actual use.

[0039] The outer periphery of the straight cylinder 140 is fixedly connected with a plurality of fixing rings 145, both sides of the fixing ring 145 are rotatably connected with connecting rods two 148, the middle part of the connecting rod two 148 is rotatably connected with connecting rods one 147, one end of the connecting rod one 147 away from the connecting rod two 148 is rotatably connected with a sliding ring 114, the sliding ring 114 is slidably connected to the outer periphery of the straight cylinder 140, the end of the connecting rod two 148 is rotatably connected with a side column 139, the side column 139 close to the material bearing bin 107 is provided with a displacement sensor, the side column 139 away from the material bearing bin 107 is in contact with the clamping plate 120, the outer periphery of the straight cylinder 140 is fixedly connected with a fixed cylinder 122, the inner upper part of the fixed cylinder 122 is fixedly connected with an air tank 149, a plurality of sealing openings 150 are arranged on the bottom of the air tank 149, the bottom of the fixed cylinder 122 is provided with a counterweight 141, the counterweight 141 is slidably connected to the outer periphery of the straight cylinder 140, the top of the counterweight 141 is fixedly connected with a plurality of lancets 136, the top of the lancet 136 penetrates through the bottom end of the fixed cylinder 122 and is slidably connected with the fixed cylinder 122, the lancet 136 corresponds to the sealing opening 150, the sliding plate 143 is arranged between the adjacent clamping plates 120, the end of the sliding plate 143 is slidably connected inside the clamping plate 120, the sliding plate 143 is slidably connected with a plurality of uniformly distributed sliding blocks 142 on both sides, the side of the sliding plate 143 close to the material bearing bin 107 is fixedly connected with a plurality of connecting pipes 144, one end of the connecting pipe 144 away from the sliding plate 143 is in communication with the straight cylinder 140;

[0040] Further, in specific implementation, when falling from a high place, the instantaneous drop of the material carrying bin 107 will cause the counterweight 141 to move relative to the straight cylinder 140 under the action of inertia, so that the spike 136 at the top of the counterweight 141 will directly insert into the sealing cap 150, thereby opening the gas tank 149, so that the compressed gas inside the gas tank 149 will gush out and enter the inside of the straight cylinder 140 through the through hole at the bottom of the straight cylinder 140. The instantaneous gushing gas will directly drive the impeller 135 inside the straight cylinder 140 to rotate, and the impeller 135 can drive the rotating shaft 125 to rotate. When the rotating shaft 125 rotates, it will drive the fixed column 115 to rise through the thread. When the fixed column 115 rises, it will drive the side columns 139 on both sides to deflect through the connecting rod one 147 and the connecting rod two 148, so that the side columns 139 expand to both sides. The side columns 139 can push the clamping plate 120 outward, so that the clamping plate 120 will contact the edge plate 138 on the inner wall of the lifting channel 101. The clamping groove 133 on the clamping plate 120 can cooperate with the clamping strip 137 on the edge plate 138, so that the clamping plate 120 can be clamped by the edge plate 138, realizing the locking of the material carrying bin 107, avoiding the further falling of the material carrying bin 107. In the process of outward deflection of the clamping plate 120, the clamping plate 120 will move relative to the sliding plate 143, thereby causing more sliding blocks 142 on the sliding plate 143 to fall out. After the gas enters the inside of the straight cylinder 140, it will be discharged into the inside of the sliding plate 143 through the connecting pipes 144, thereby causing the exposed sliding blocks 142 to be ejected, so that the sliding blocks 142 can avoid the retraction of the clamping plate 120, keeping the stability of the clamping plate 120, so that the clamping plate 120 can stably engage with the edge plate 138, realizing the locking of the material carrying bin 107, avoiding the continuous falling of the material carrying bin 107, which is beneficial to actual use.

[0042] Further, in specific implementation, further, when the material bearing bin 107 is in an unexpected state in the lower section of the lifting channel 101, the material bearing bin 107 cannot be locked in time or appears an incomplete locking state, the impact of the material bearing bin 107 on the buffer platform 108 can compress the buffer bin 127, so that when the buffer bin 127 buffers the force, the gas in the buffer bin 127 can directly enter the bottom plate of the material bearing bin 107 through the buffer platform 108, the hole arranged in the bottom plate of the material bearing bin 107 can guide the gas into the straight cylinder 140, thereby achieving the emergency locking of the material bearing bin 107, which is beneficial to actual use.

[0044] In the mining process, people can collect the minerals at the bottom of the mine by the material lifting machine to the ground, realize the lifting and transfer of the collected minerals, in the work, through the work of the reduction motor 110 can drive one of the winding roller 111 to rotate, through the meshing gear between the winding roller 111 can make two winding roller 111 synchronous rotation, through the winding roller 111 can winding and relaxing of the sling 103, through the sling 103 can pull the bottom of the material carrying bin 107 to lift, so as to be able to through the material carrying bin 107 to the mineral material and production material lifting or unloading, in the process of material carrying bin 107 work, when the material carrying bin 107 starts to lift, the distance sensor on the top of the buffer column 124 will send a signal to start the lead screw inside the guide groove 130, through the work of the lead screw can drive the scissors bar 128 through the slide 129 to work, so as to be able to through the scissors bar 128 to support the plate 134 and the buffer platform 108 to lift, so that the buffer platform 108 can be lifted with the material carrying bin 107, when the buffer platform 108 is lifted to the limit, through the bottom of the buffer platform 108 fixed cover 116 can seal the mouth 106, so as to be able to through the cover 116 and the bottom bin 109 to realize the protection work of the bottom buffer unloading part of the lifting machine, avoid the foreign matter into the lifting channel 101 inside, affect the work of the lifting machine, when the material carrying bin 107 is lifted to the top, will reach the mouth 102, facilitate people to transfer the material, in the process of material carrying bin 107 descending, when the material carrying bin 107 falls to the distance sensor detection range on the top of the buffer column 124, the bottom lead screw will work again, so that the buffer platform 108 can be lowered with the material carrying bin 107, so that the material carrying bin 107 can be lowered to the mouth 106, facilitate people to take the material, in actual use, when the material carrying bin 107 in the working process appears accident, cause the material carrying bin 107 to fall, because the buffer platform 108 is lifted, will seal the bottom space of the lifting channel 101, so that the bottom of the material carrying bin 107 is airtight space, so as to make the material carrying bin 107 and the lifting channel 101 form an air buffer, so as to effectively slow down the falling speed of the material carrying bin 107, reduce the impact, at the same time, through the lifting of the buffer platform 108 can seal the mouth 106, avoid the material carrying bin 107 speed down after the collision, the internal material splash through the mouth 106 fly out caused by additional injury, when the material carrying bin 107 impact on the buffer platform 108, through the multiple top spring 123 on the buffer column 124 can fully buffer and dissipate energy, and make the connecting head 126 on the top of the buffer platform 108 can contact with the connecting port on the bottom of the material carrying bin 107, so as to be able to through the buffer platform 108 to lock the material carrying bin 107, so as to avoid the material carrying bin 107 impact again after bounce,Further damage is caused, while the buffer station 108 can be buffered through the buffer compartment 127 between the buffer station 108 and the supporting plate 134, reducing the impact of the material carrying compartment 107 to the buffer station 108, while the supporting plate 134 can be further buffered through the buffer sleeve 132 at the bottom of the supporting plate 134. The impact force of the material carrying compartment 107 is maximized and buffered through multiple buffering and damping processes, which is beneficial to actual use. When falling from a high place, the instantaneous drop of the material carrying compartment 107 will cause the counterweight 141 to move relative to the straight cylinder 140 under the action of inertia, so that the spike 136 at the top of the counterweight 141 will be directly inserted into the seal 150, thereby opening the gas tank 149, so that the compressed gas inside the gas tank 149 will gush out and enter the straight cylinder 140 through the hole at the bottom of the straight cylinder 140. The instantaneous gushing of gas will directly drive the impeller 135 inside the straight cylinder 140 to rotate, which can drive the rotating shaft 125 to rotate through the impeller 135. When the rotating shaft 125 rotates, it will drive the fixed column 115 to rise through the screw thread, and when the fixed column 115 rises, it will drive the side columns 139 on both sides to deflect through the connecting rod one 147 and the connecting rod two 148, so that the side columns 139 expand to both sides. Through the side columns 139, the clamping plate 120 can be pushed outward, so that the clamping plate 120 will contact the edge plate 138 on the inner wall of the lifting channel 101, and the clamping strip 137 on the edge plate 138 can cooperate with the clamping groove 133 on the clamping plate 120, so that the clamping plate 120 can be clamped by the edge plate 138. 120 is locked to avoid further falling of the material carrying compartment 107. During the outward deflection of the clamping plate 120, the clamping plate 120 will move relative to the sliding plate 143, thereby causing more sliding blocks 142 on the sliding plate 143 to fall out. After the gas enters the straight cylinder 140, it will be discharged into the sliding plate 143 through the connecting pipes 144, thereby causing the exposed sliding blocks 142 to be ejected, so that the sliding blocks 142 can prevent the clamping plate 120 from retracting, keeping the clamping plate 120 stable, so that the clamping plate 120 can stably engage with the edge plate 138, achieving the locking of the material carrying compartment 107, avoiding the material carrying compartment 107 from falling further, which is beneficial to actual use. Further, when the material carrying compartment 107 falls unexpectedly at the lower section of the lifting channel 101, causing the material carrying compartment 107 to be unable to be locked or in an incomplete locking state, the impact of the material carrying compartment 107 on the buffer station 108 will cause the buffer compartment 127 to be compressed, so that the gas in the buffer compartment 127 will enter the bottom plate of the material carrying compartment 107 through the buffer station 108 when the buffer compartment 127 is buffered and damped. The hole in the bottom plate of the material carrying compartment 107 can guide the gas into the straight cylinder 140, achieving emergency locking of the material carrying compartment 107, which is beneficial to actual use.
