Detailed Embodiments

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , a rope splitting device for the lower platform of an inclined roadway, which includes a vertically arranged rope splitting rod 3. The rope splitting rod 3 includes two end rods 14. A sliding rod 17 is slidably connected between the two end rods 14. The two end rods 14 are respectively connected to the top and bottom of the roadway through a connecting mechanism 1. The connecting mechanism 1 includes a connecting seat 4 fixedly connected to the top or bottom of the roadway. A cavity 7 is provided in the connecting seat 4. A slider 9 is slidably arranged in the cavity 7. The two end rods 14 are respectively rotatably connected to the two sliders 9.

[0024] When in use, the rope splitting device is arranged on the lower platform of the inclined roadway 1 and is located between the upward track and the downward track of the inclined roadway 1. At this time, the traction ropes used for the upward track and the downward track are respectively located on both sides of the rope splitting device. When the hookman at the lower platform mis-operates the turnout, the upward mine car will be transferred to the downward track. During the process of the upward mine car moving upward along the downward track, the traction rope will be blocked by the rope splitting rod 3, thereby blocking the upward mine car and preventing the upward mine car from colliding with the downward mine car on the downward track. Moreover, because the end rod 14 is slidably connected to the sliding rod 17 and the end rod 14 is rotatably connected to the slider 9, the length and angle of the rope splitting rod 3 can change when blocking the traction rope, which can not only play a buffering role, but also enable the hookman to quickly understand whether the turnout is mis-operated by observing the posture of the rope splitting rod 3, and then quickly make corresponding countermeasures.

[0025] The present invention can block the wrong traction rope when the hookman at the lower platform of the inclined roadway mis-operates the turnout, prevent the upward mine car and the downward mine car from colliding and causing accidents such as derailment of the mine car or even breakage of the rope and running away of the car, and enable the hookman to quickly discover the mis-operation of the turnout and then quickly take corresponding countermeasures.

[0026] The specific sliding connection method between the end rod 14 and the sliding rod 17 is as follows: a slideway 15 extending axially is provided on the end rod 14. The slideways 15 on the two end rods 14 are arranged opposite to each other. The two ends of the sliding rod 17 are respectively slidably arranged in the two slideways 15. By arranging the sliding rod 17 in the slideway 15, the end rod 14 can be used to limit the sliding rod 17 to prevent the sliding rod 17 from deflecting laterally and separating from the end rod 14, thereby avoiding damage to the rope splitting rod 3.

[0027] In order to enable the rope separating rod 3 to quickly reset after the hook worker makes a response, a spring 16 is arranged in one of the sliding channels 15, and the spring 16 is fixedly connected to the sliding rod 17. After the hook worker makes a response, the towing rope is separated from the rope separating rod 3. Under the action of the spring 16, the sliding rod 17 is pulled to reset, so that the length of the rope separating rod 3 is reset.

[0028] The use of the spring 16 can reset the length of the rope separating rod 3, but it cannot reset the angle of the rope separating rod 3. In order to enable the angle of the rope separating rod 3 to also be reset, so that the rope separating rod 3 can be completely restored to its initial state, a plurality of sleeves 5 are fixedly arranged in the cavity 7 and are evenly distributed along the circumferential direction of the slider 9. The sleeves 5 are filled with gas 11, and a push rod 6 is also slidably arranged in the sleeves 5. After the push rod 6 extends out of the sleeve 5, it is fixedly connected to the slider 9. When the rope separating rod 3 contacts the towing rope, its angle changes under the action of the towing rope. During this process, the slider 9 is driven to move in the cavity 7. When the slider 9 moves, several of the push rods 6 are driven to move into the corresponding sleeves 5, and the gas 11 in the sleeves 5 is compressed. After the rope separating rod 3 is separated from the towing rope, the gas 11 loses pressure and expands. During this process, the push rod 6 is pushed to extend out of the sleeve 5, so as to use the push rod 6 to reset the slider 9. After the slider 9 is reset, the two end rods 14 are reset, so that the angle of the rope separating rod 3 is reset.

[0029] In order to enable the hook worker to more quickly discover the situation where the switch is wrongly switched, a pressure sensor 13 is fixedly arranged in the sleeve 5, and a piston 12 is arranged between the pressure sensor 13 and the push rod 6. All the pressure sensors 13 are commonly electrically connected to a controller, and the controller is also electrically connected to a buzzer and an alarm lamp. When the push rod 6 moves inward into the sleeve 5, the gas 11 is compressed. The gas 11 pushes the piston 12 to move towards the pressure sensor 13. Until the piston 12 triggers the pressure sensor 13, the controller collects the signal of the pressure sensor 13 and controls the buzzer and the alarm lamp to act, so as to send a reminder to the hook worker and enable the hook worker to more quickly discover the danger.

[0030] In order to improve the sealing performance of the sleeve 5 and prevent the gas 11 from leaking, a hose 8 is connected between the sleeve 5 and the slider 9, and the push rod 6 is located inside the hose 8.

[0031] The specific connection method between the end rod 14 and the sliding block 9 is as follows: a hemispherical receiving groove is formed on the slider 9, and the end rod 14 is fixedly connected with a contact ball 10. The contact ball 10 is arranged in the receiving groove in a matching manner. Under the action of the spring 16, the two end rods 14 are continuously pushed towards both ends, so that the contact ball 10 can be closely attached to the inner wall of the receiving groove and will not be separated from the slider 9, and the contact ball 10 can roll in the receiving groove, so that the angle of the rope separating rod 3 can change with the action of the towing rope.

[0032] In order to facilitate the quick response and handling of the hook worker, a number of cylindrical guiding blocks 18 are rotatably sleeved on the end rod 14 and the sliding rod 17 respectively. At both ends of the guiding block 18, there is an annular guiding surface 20, and an annular groove 19 extending in the circumferential direction is provided in the middle of the guiding block 18. The guiding surface 20 is set as an annular arc surface. When the guiding block 18 contacts the towing rope, the towing rope can slide along the guiding surface 20 and finally move into the annular groove 19. After that, the towing rope is limited by the annular groove 19. Since the position of the guiding block 18 on the end rod 14 or the sliding rod 17 is fixed, the position of the towing rope after entering the annular groove 19 is also fixed, thus facilitating the operation of the hook worker.

[0033] The specific setting method of the guiding block 18 is as follows: at both ends of the guiding block 18, it is rotatably connected to the end rod 14 or the sliding rod 17 through a bearing 21 respectively. Correspondingly, two annular mounting grooves are provided on the inner wall of the guiding block 18, the outer ring of the bearing 21 is fixedly connected to the inner wall of the mounting groove, and the end rod 14 or the sliding rod 17 is fixedly inserted into the inner hole of the bearing 21.

[0034] A method for separating ropes on the lower platform of an inclined roadway, based on the above-mentioned rope separating device on the lower platform of an inclined roadway, includes S1 to S2.

[0035] S1. Set the rope separating device on the lower platform of the inclined roadway, and make the rope separating device located between the upward track and the downward track of the inclined roadway 1.

[0036] S2. When the upward mine car switches from the upward track to the downward track, the towing rope of the upward mine car is blocked by the rope separating rod 3, forcing the upward mine car to stop.
