Description

Technical Field

[0001] The utility model relates to the technical field of tailings transportation, and more specifically, to a device for preventing longitudinal tearing of a belt. Background Art

[0002] Tailings are the solid waste remaining after the concentrate is separated from the ore. They are mainly formed by natural dehydration of the tailings slurry discharged from the ore dressing plant. They are the main component of solid industrial waste and contain a certain amount of useful metals and minerals. They are characterized by fine particle size, large quantity, low cost and high availability.

[0003] With the development of automation and intelligent construction in mining enterprises, enterprises have begun to carry out automation upgrades and renovations in order to achieve the goal of reducing costs and increasing efficiency. Along with this, there is the problem of equipment inspection. At present, when transporting tailings, belts are usually used to transport tailings to a suitable location for centralized processing. In order to avoid damage to the belt during automated transportation, a rope is usually placed horizontally at the bottom of the belt. When a horizontal fracture occurs on the belt, the belt will fall and hit the pull rope switch, thereby stopping the belt transportation operation. Although the device can effectively protect the belt when the belt is horizontally cracked, when transporting tailings, the tailings material often contains particles of various sizes and hardness, which may contain sharp debris or large pieces of material. These materials may scratch or jam the belt during transportation, thereby causing longitudinal tearing. The device cannot protect the longitudinally torn belt, resulting in continuous operation of the belt, increasing economic damage, so it needs to be improved and optimized. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 5As shown, the utility model provides a device for preventing longitudinal tearing of a belt, comprising a transport bracket 1, a transmission roller 2 is rotatably installed inside the transport bracket 1, there are two groups of transmission rollers 2, and they are rotatably installed at the left and right ends of the transport bracket 1, and the two groups of transmission rollers 2 are connected by a belt 3;

[0026] The sensing mechanism is fixedly mounted on the front side of the transport bracket 1;

[0027] The guide mechanism is fixedly mounted on the rear side of the transport bracket 1 and is fixedly connected to the transport bracket 1;

[0028] The anti-longitudinal tearing mechanism is fixedly installed on the front side of the transport bracket 1, and one end of the anti-longitudinal tearing mechanism is fixedly connected to the sensing mechanism;

[0029] Among them, the sensing mechanism includes a fixed bracket 8 fixedly installed on the front side of the transport bracket 1, a fixed bracket 2 9 is fixedly installed on the left side of the fixed bracket 8, and a rotating wheel 10 is rotatably installed on the top of the fixed bracket 2 9, the fixed bracket 8 is fixedly connected to the rope 11, one end of the rope 11 passes through the connecting rod 12, and passes through the top of the rotating wheel 10, and is fixedly connected to one end of the anti-longitudinal tearing mechanism. There are two groups of connecting rods 12, both of which are movably connected to the rope 11, the two groups of connecting rods 12 are fixedly connected to the receiving hopper 13, and the rope 11 and the rotating wheel 10 are in conflict with each other.

[0030] When it is necessary to transport tailings, the staff first aligns the contact 20 and the contact point on the surface of the control mechanism 21 and makes them contact with each other. At this time, the elastic potential energy of the spring 19 will pull up the connecting rod 12 through the rope 11. At this time, the receiving hopper 13 is in a suspended state and starts to detect the state of the belt 3. At this time, the contact 20 and the contact point are in contact with each other, so that the control mechanism 21 controls the motor 5 through the control line 22, so that the motor 5 starts to operate. At this time, the motor 5 drives the transmission mechanism 4 to make the transmission drum 2 start to rotate, and further makes the belt 3 start to transport to the left. When the tailings are transported, if the belt 3 is torn longitudinally, the tailings will pass through the crack from the upper layer of the belt 3 and fall into The lower layer of the belt 3, at this time, the lower belt 3 will transport the detached tailings to the right, and the tailings will pass through the guide rod 7, be guided by the guide rod 7 and finally fall into the receiving hopper 13. When the receiving hopper 13 contains tailings, the receiving hopper 13 will fall to the ground, thereby pulling the rope 11 through the connecting rod 12. When the rope 11 is pulled, the rope 11 generates a rightward pulling force through the guidance of the rotating wheel 10, and the pulling force will pull the rope 11 outward from the limit cylinder 17, so that the contact 20 is disengaged from the contact point. When the contact 20 is disengaged from the contact point, the control mechanism 21 will control the control line 22 through the PRC control system to turn off the motor 5, so that the belt 3 stops transporting.

[0031] Through the elastic potential energy of the spring 19, the rope 11 supports the receiving hopper 13. When the belt 3 is torn longitudinally, the tailings will fall into the receiving hopper 13 through the transportation of the lower belt 3 and the diversion of the guide rod 7. When the weight of the receiving hopper 13 increases, the receiving hopper 13 will fall to the ground. At this time, the contact 20 is pulled out through the transmission of the rope 11, and the operation of the belt 3 is further stopped by the control mechanism 21. Compared with the traditional device, the device makes the fallen tailings fall into the receiving hopper 13 through the setting of the guiding mechanism and the sensing mechanism. At this time, the anti-tearing mechanism is operated, and the belt 3 is stopped through the control mechanism 21, thereby avoiding the continuous operation of the belt 3, resulting in an increase in the belt tear, and avoiding secondary damage. The loss can be effectively minimized and the economic loss is reduced.

[0033] When the belt 3 is torn longitudinally during tailings transportation, the tailings will pass through the crack from the upper layer of the belt 3 and fall into the lower layer of the belt 3. At this time, the lower belt 3 will transport the detached tailings to the right, and the tailings will pass through the guide rod 7, be guided by the guide rod 7 and finally fall into the receiving hopper 13.

[0035] When the receiving hopper 13 contains tailings, the receiving hopper 13 will fall to the ground, and the wire rope 11 will be pulled outward from the limiting cylinder 17, so that the contact 20 will be separated from the contact point.

[0036] Among them, a motor 5 is fixedly installed on the front side of the transport bracket 1, the output shaft of the motor 5 is fixedly connected to one end of the transmission mechanism 4, the other end of the transmission mechanism 4 is fixedly connected to the right transmission roller 2, and the transmission mechanism 4 is fixedly arranged on the front side of the transport bracket 1.

[0037] When the contact 20 and the contact point are in contact with each other, the control mechanism 21 controls the motor 5 through the control line 22, so that the motor 5 starts to operate. At this time, the motor 5 drives the transmission mechanism 4 to make the transmission roller 2 start to rotate, and further makes the belt 3 start to transport to the left.

[0038] Among them, one end of the fixed head 18 and the inner wall of the control box 15 are elastically connected through a spring 19 , and the elastic potential energy of the spring 19 can lift the receiving hopper 13 through the rope 11 .

[0043] Instructions for use or methods of operation of a technology;

[0044] When it is necessary to transport tailings, the staff first aligns the contact 20 and the contact point on the surface of the control mechanism 21 and makes them contact with each other. At this time, the elastic potential energy of the spring 19 will pull up the connecting rod 12 through the rope 11. At this time, the receiving hopper 13 is in a suspended state and starts to detect the state of the belt 3. At this time, the contact 20 and the contact point are in contact with each other, so that the control mechanism 21 controls the motor 5 through the control line 22, so that the motor 5 starts to operate. At this time, the motor 5 drives the transmission mechanism 4 to make the transmission drum 2 start to rotate, and further makes the belt 3 start to transport to the left. When the tailings are transported, if the belt 3 is torn longitudinally, the tailings will pass through the crack from the upper layer of the belt 3 and fall into The lower layer of the belt 3, at this time, the lower belt 3 will transport the detached tailings to the right, and the tailings will pass through the guide rod 7, be guided by the guide rod 7 and finally fall into the receiving hopper 13. When the receiving hopper 13 contains tailings, the receiving hopper 13 will fall to the ground, thereby pulling the rope 11 through the connecting rod 12. When the rope 11 is pulled, the rope 11 generates a rightward pulling force through the guidance of the rotating wheel 10, and the pulling force will pull the rope 11 outward from the limit cylinder 17, so that the contact 20 is disengaged from the contact point. When the contact 20 is disengaged from the contact point, the control mechanism 21 will control the control line 22 through the PRC control system to turn off the motor 5, so that the belt 3 stops transporting.
