By setting a plastic shell at the air hole of the emergency brake box, when the cable breaks suddenly, the compensation box moves upward quickly, and the emergency brake box quickly inhales a large amount of air from the outside through the air hole. The suction force of the air hole causes the plastic shell to deform, and the middle part of the plastic shell is concave and fully contacts with the air hole of the emergency brake box, so that the air hole of the emergency brake box is blocked, and the outside air cannot be replenished into the emergency brake box. The negative pressure in the emergency brake box, combined with the pulling of the elastic part III on the compensation box, tightly pulls the compensation box, and then pulls the hopper, effectively avoiding the sudden breakage of the cable, causing the hopper to suddenly fall, and the material in the hopper to pour out, causing the personal safety of the operator to be threatened.

[0018] 3. By transferring the lubricating oil to the oil seepage holes in the groove of the oil brush plate, the cable passes through the groove of the oil brush plate. The lubricating oil not only reduces the friction between the groove of the oil brush plate and the cable, but also transfers the lubricating oil to the cable, thereby applying the lubricating oil to the cable, preventing the cable from rusting and increasing the service life of the cable.

[0039] The working steps of the above embodiment are:

[0040] When it is necessary to lift the hopper to transport materials in the mine, then open the locking switches of all the traveling wheels 2 to fix the traveling wheels 2 so that the equipment will not move during lifting, and then control the winch 5 to release the wound cable 6 to lower the pulley block 7 and the hook 8, the pulley block 7 drives the limiter 9 to move downward, the limiter 9 pulls the two protection ropes 10 downward, and the two protection ropes 10 jointly pull the corresponding piston plate 12 upward, and the corresponding spring rod 13 in each compensation box 11 is compressed. When the hopper is directly below the hook 8, the hopper can be directly hooked with the hook 8. When the hopper is not directly below the hook 8, the electric slide block 4 is controlled to move on the corresponding electric slide rail 3, synchronously driving the winch 5 and the corresponding parts thereon to move, and the limiter 9 is between the two The protective rope 10 slides, and the ball 304 on the limiter 9 contacts with the protective rope 10, reducing the wear of the protective rope 10 and the limiter 9, until the hook 8 hooks the hopper. At this time, the winch 5 is controlled to roll up the cable 6, and the pulley block 7 and the corresponding parts thereon move upward synchronously. All the spring rods 13 slowly recover, and the hook 8 lifts the hopper. Then the electric slider 4 is controlled to move to the middle of the electric slide rail 3, and the winch 5 and the corresponding parts thereon are driven to move to the middle area of ​​the portal frame 1 synchronously. The limiter 9 slides on the protective rope 10 until the limiter 9 moves to the middle of the protective rope 10, so that the hopper is transferred to the middle of the portal frame 1, the electric slider 4 is controlled to stop, and then the locking switch of the running wheel 2 is unlocked. The operator can push the equipment to transport the hopper to the target location.

[0041] After the hopper is lifted, if it is necessary to move the hopper left and right, the stopper 9 folds the two protection ropes 10 into a Figure 1 The V-shaped structure shown in the figure makes the pulley block 7 have strong stability. When the electric slider 4 stops moving, the pulley block 7 used to pull the hook 8 and the hopper on it is limited by the limiter 9, and the left and right shaking of the pulley block 7 is quickly stopped. When the hopper shakes left and right, the protective rope 10 is also pulled by the limiter 9. The end of the protective rope 10 on the side opposite to the shaking direction of the hopper is driven to move upward, and the synchronous protective rope 10 pulls the corresponding piston plate 12 to move upward, and the corresponding spring rod 1 connected to the piston plate 12 is 3 is compressed, and the spring rod 13 absorbs the energy of the upward movement of the piston plate 12 through its damping effect. At the end of the protective rope 10 on the side of the hopper shaking direction, the corresponding spring rod 13 is restored, and the piston plate 12 is synchronously driven to move downward, so that the piston plate 12 drives the end of the protective rope 10 to move downward, thereby absorbing the energy of the left and right shaking of the hopper through the spring rods 13 on the left and right sides, and then slowly releasing it, effectively avoiding the violent left and right shaking of the hopper, causing the shaking of the equipment, and even the tipping of the equipment.

[0042] Then, after the bucket is lifted, when the device is pushed to move, the bucket sways back and forth due to the influence of wind force. At this time, the pulley block 7, hook 8, limiter 9 and bucket deviate from the bottom of the winch 5, and the cable 6 is inclined. At this time, the protective rope 10 is also pulled by the limiter 9 to deviate in the direction of the bucket deviation. At this time, the movable block 103 through which the protective rope 10 passes is also pulled to slide on the corresponding slide bar 102. The sliding direction of the movable block 103 is the side of the bucket deviation. When the movable block 103 moves, the elastic member Ⅰ104 on the moving direction of the movable block 103 is compressed, and the elastic member Ⅰ104 on the other side of the movable block 103 is stretched. Under the combined action of the stretched or compressed elastic member Ⅰ104 and the cable 6, after the bucket is pulled, the bucket begins to swing in the moving direction of the device. As the hopper moves, the hook 8, the pulley block 7 and the limiter 9 also move accordingly, the protective rope 10 is pulled, and then the movable block 103 also moves accordingly. The elastic member Ⅰ104 used to limit the movable block 103 absorbs the movement energy of the movable block 103 through the damping effect, so that the movable block 103 returns to its initial position, and then the movable block 103 reacts to the corresponding protective rope 10. The protective rope 10 limits the pulley block 7 through the limiter 9, and then finally the shaking of the hook 8 and the hopper in the front and rear directions gradually decreases, and the hopper is stably suspended under the winch 5. The energy of the hopper's front and rear shaking is absorbed by the elastic members Ⅰ104 on both sides of the movable block 103, and then slowly released, which effectively prevents the hopper from shaking violently back and forth, causing the shaking of the equipment and the tipping of the equipment.

[0043] Taking into account that the cable 6 will be worn out after the equipment has been used for a certain period of time, when part of the cable 6 suddenly breaks, the pulley block 7 loses part of its tension, and the pulley block 7 falls downward, synchronously driving the limiter 9 to move downward, so that the middle part of the protective rope 10 is quickly pulled down, and the piston plates 12 connected at both ends are quickly pulled up, and the corresponding spring rods 13 are compressed to buffer the movement of the piston plate 12. At the same time, when the piston plate 12 moves upward in the compensation box 11, the compensation box 11 draws air from the emergency brake box 201 through the small holes at the bottom, and the emergency brake box 201 draws air from the outside through the air holes. The speed of the air entering the compensation box 11 can be adjusted by setting the number of small holes at the bottom of the compensation box 11, and then the upward movement speed of the piston plate 12 is limited by air pressure, thereby buffering the fall of the hopper.

[0044] And after part of the cable 6 breaks, the center of gravity of the pulley block 7, the hook 8, the limiter 9 and the hopper shifts to one side, so that the limiter 9 slides on the protective rope 10 toward the side away from the broken cable 6. At this time, all the electric actuators 301 are controlled to contract, and the corresponding mounting plates 302 and the corresponding parts thereon are synchronously driven to move toward the side close to the protective rope 10 until the friction strip 303 contacts the corresponding protective rope 10 and presses the protective rope 10 against the limiter 9. The movement speed of the limiter 9 relative to the protective rope 10 is reduced until the limiter 9 stops, effectively preventing the hopper from shaking too much after the cable 6 breaks, and the material in the hopper is easily thrown out.

[0045] Then the spring rod 13 is compressed to the limit, the piston plate 12 drives the spring rod 13 and the compensation box 11 to move upward, the compensation box 11 moves upward relative to the emergency brake box 201, negative pressure is generated in the emergency brake box 201, and the emergency brake box 201 quickly inhales a large amount of air from the outside through the air hole. At this time, since the air hole of the emergency brake box 201 is provided with a plastic shell 203 for dust prevention, the plastic shell 203 moves toward the air hole due to the suction force of the air hole. When the plastic shell 203 contacts the outer surface of the emergency brake box 201, the suction force of the air hole causes the plastic shell 203 to deform, such as Figure 5 As shown, the middle part of the rubber shell 203 is concave and fully contacts with the air holes of the emergency brake box 201, so that the air holes of the emergency brake box 201 are blocked, and the outside air cannot be replenished into the emergency brake box 201. The negative pressure in the emergency brake box 201, together with the elastic member III 205 pulling the compensation box 11, tightly pulls the compensation box 11, and then pulls the hopper, effectively preventing the cable 6 from breaking suddenly, causing the hopper to suddenly fall, and the material in the hopper to pour out, causing the personal safety of the operator to be threatened.

[0046] At this time, the hopper is held by two protection ropes 10. The operator only needs to turn the knob 206 to allow the air to slowly pass through the pressure relief hole 20101 and enter the emergency brake box 201. The compensation box 11 moves slowly upward until the hopper falls to a safe position. The operator then goes up to separate the hook 8 from the hopper, effectively preventing the protection rope 10 from suddenly breaking and the hopper from suddenly falling, causing a danger.

[0047] On the basis of the above technical effects, the present invention also has the following advantages:

[0048] Under normal circumstances, the plastic shell 203 can be used to prevent dust from the air holes of the emergency brake box 201. After a number of air holes are opened on the edge of the plastic shell 203, when the hook 8 moves downward to contact the hopper, the piston plate 12 will also move upward, and the compensation box 11 needs air replenishment. The outside air can enter the compensation box 11 through the air holes of the emergency brake box 201, and the hook 8 slowly descends, and the air slowly enters the emergency brake box 201, which will not cause the deformation of the plastic shell 203. Only when emergency braking is needed, the plastic shell 203 will be deformed to block the air holes of the emergency brake box 201, so that the normal function of the equipment is not affected.

[0049] Second embodiment

[0050] On the basis of the first embodiment, according to Figure 1-Figure 2 and Figure 7-10 As shown, the limiter 9 includes a fixed block 9001 and an oil brushing plate 9002; the fixed part of the pulley block 7 is fixedly connected to the fixed block 9001; an oil storage cavity is opened in each fixed block 9001; the fixed block 9001 is fixedly connected to two oil brushing plates 9002 distributed front and back; each protective rope 10 passes through an oil brushing plate 9002; the ball 304 is installed on the corresponding oil brushing plate 9002; each oil brushing plate 9002 has an accommodating cavity inside; a plurality of oil delivery holes are opened on the oil storage cavity of the fixed block 9001; the accommodating cavities of all the oil brushing plates 9002 are connected with the oil delivery holes of the fixed block 9001; a plurality of grooves are opened on the oil brushing plate 9002, and the number of the grooves corresponds to the number of cables 6 passing through the oil brushing plate 9002; a plurality of oil seepage holes are opened on the groove of each oil brushing plate 9002; and the accommodating cavities of each oil brushing plate 9002 are connected with the corresponding oil seepage holes.

[0051] It also includes a sponge block 9003; each sponge block 9003 is detachably connected to the accommodating cavity of each oil brushing plate 9002; each sponge block 9003 is located between the corresponding oil delivery hole and the oil seepage hole.

[0052] The working steps of the above embodiment are:

[0053] Before using the device, first insert two sponge blocks 9003 into the receiving chamber of an oil brush plate 9002, then open the cover of the oil storage chamber of the fixed block 9001, pour lubricating oil into the oil storage chamber, and then re-cover the cover of the oil storage chamber, so that the lubricating oil in the oil storage chamber of the fixed block 9001 enters the receiving chamber of the oil brush plate 9002 through the oil delivery hole, the sponge block 9003 absorbs the lubricating oil, and then the excess lubricating oil is dispersed to the groove of the oil brush plate 9002 through the sponge block 9003 The lubricating oil overflows from the oil seepage hole, and at this time there is a cable 6 in the groove of the oil brush plate 9002. Therefore, when the present device is used, the hook 8 needs to be lowered or raised, and at this time the winch 5 needs to frequently reel in or release the cable 6. The cable 6 passes through the groove of the oil brush plate 9002, and the lubricating oil not only reduces the friction between the groove of the oil brush plate 9002 and the cable 6, but also transfers the lubricating oil to the cable 6, thereby realizing the application of the lubricating oil to the cable 6, avoiding the cable 6 from rusting, and increasing the service life of the cable 6.
