Description

Technical Field

[0001] The invention belongs to the technical field of mine hoist accessories, in particular to a mine hoist wire rope fault early warning alarm device. Background Art

[0002] Mine hoists are hoisting machines installed on the ground, which use wire ropes to drive the hoisting container along the shaft or ramp. Since mine hoists mainly use wire ropes to complete the tasks of lifting and lowering heavy objects, the wire ropes are prone to wear and breakage after long-term operation. Once the wire rope fails, it may cause serious accidents such as the fall of the hoisting container. By real-time monitoring of the status of the wire rope, potential faults can be discovered and handled in time to avoid accidents and reduce economic losses.

[0003] The patent with announcement number CN221479204U discloses a mine hoist wire rope fault early warning alarm device, which relates to the technical field of mine hoist accessories, including a monitoring structure and an alarm structure. The monitoring structure includes a positioning part and a monitoring part. The monitoring part includes two connecting arms assembled between the middle parts of two columns, and the same assembly ring is integrally formed between one end of the two connecting arms. Two movable pulleys are arranged on the inner side of the assembly ring, and pressure sensors are arranged on one side of the two movable pulleys. The bottom of the frame plate is assembled and connected with a processor and a buzzer. The technical key points are: by passing the wire rope that passes from the top of the reversing wheel to the bottom vertically through the two positioning pulleys, and in the process of moving up and down, the area with enlarged diameter will push the two movable pulleys away from each other, pressing the pressure sensor on the support block, and finally the support block sends a signal to the processor, and the processor controls the buzzer to send an alarm to the mine, which is conducive to improving construction safety.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] By setting two movable pulleys that fit the wire rope, when the wire rope breaks, the diameter of the broken wire area will increase, and push the two movable pulleys to move, pressing the pressure sensor on the support block, and finally the support block sends a signal to the processor, and the processor controls the buzzer to alarm the mine. However, since there are two movable pulleys, the buzzer can only sound an alarm when the contact position between the wire rope and the movable pulley is deformed, which is prone to detection blind spots. In addition, since the spacing of the movable pulleys depends on the diameter of the wire rope, even if the number of movable pulleys is increased, the spacing between adjacent movable pulleys will increase due to the excessive diameter of the wire rope, and the detection blind spot will still occur. In addition, in general, when the wire rope is detected to be faulty, the worker needs to determine the specific damage point of the wire rope to take appropriate repair measures, such as cutting off the damaged part, reconnecting or replacing a new wire rope, etc. In a complex industrial environment, the wire rope may be hundreds of meters long, and it is difficult for the worker to find the damage point of the wire rope, which in turn affects the subsequent repair measures for the wire rope.

[0035] The spraying mechanism includes a connecting pipe 6 fixedly connected to the upper and lower sides of the support frame 1. One end of the connecting pipe 6 is connected and fixedly connected to an annular pipe 28. A plurality of spray heads 29 are radially distributed and arranged on the annular pipe 28.

[0036] In this embodiment, Figure 1-Figure 8 As shown, a plurality of slide bars 9 are fixedly connected to the upper end surface of the mounting ring 8, and the slide bars 9 are slidably connected to the adjusting ring 11. A spring 10 is sleeved on one side of the slide bar 9, and the upper and lower ends of the spring 10 are fixedly connected to the slide bar 9 and the adjusting ring 11 respectively.

[0037] An electric push rod 19 is fixedly connected to one side of the support frame 1, and the piston end of the electric push rod 19 is fixedly connected to the upper end surface of the connecting plate 20.

[0038] A paint box 4 is fixedly connected to one side of the right end face of the support frame 1, and a feeding port 12 is provided on one side of the upper end of the paint box 4. The upper and lower sides of the paint box 4 are connected and fixedly connected to a pump body 5, and the discharge end of the pump body 5 is fixedly connected to one end of a connecting pipe 6.

[0039] The spray head 29 penetrates through and is fixedly connected to the housing 30 . The steel wire rope can move up and down in the inner cavity of the housing 30 , and the spray head 29 is aimed at the surface of the steel wire rope.

[0040] The support frame 1 is fixedly connected to support rings 34 on both the upper and lower sides. The support ring 34 is radially distributed and slidably connected to multiple sliding rods 35. One end of the sliding rod 35 is fixedly connected to a stretching rod 27. The upper and lower ends of the stretching rod 27 are fixedly connected to a shielding cloth 25. The shielding cloth 25 is made of elastic material and fits the end surface of the shell 30.

[0041] A through hole 26 is provided in the middle of the shielding cloth 25 . The through hole 26 is circular and a steel wire rope can pass through the through hole 26 .

[0042] A buzzer 21 is provided on one side of the support frame 1. When the pressure rod 23 contacts the pressure sensor 22, the pressure sensor 22 detects a pressure signal and the buzzer 21 sounds.

[0043] An electric push rod 2 31 is fixedly connected to one side of the support ring 34, and an adjusting ring 2 33 is fixedly connected to the piston end of the electric push rod 2 31. A plurality of connecting rods 2 32 are radially distributed and rotatably arranged on the adjusting ring 2 33, and one end of the connecting rod 2 32 is rotatably connected to one end of the sliding rod 4 35.

[0044] Specifically, the existing mine hoist wire rope fault early warning alarm device is used by setting two movable pulleys 16 that fit the wire rope. When the wire rope breaks, the diameter of the broken wire area will increase, and push the two movable pulleys 16 to move, pressing the pressure sensor 22 on the support block, and finally the support block sends a signal to the processor, and the processor controls the buzzer 21 to send an alarm to the mine. However, since there are two movable pulleys 16, the buzzer 21 can only send an alarm when the contact position between the wire rope and the movable pulley 16 is deformed, which is prone to detection blind spots, and Since the spacing of the movable pulleys 16 depends on the diameter of the wire rope, even if the number of movable pulleys 16 is increased, the spacing between adjacent movable pulleys 16 will become larger due to the excessive diameter of the wire rope, and there will still be a detection blind spot. In addition, in general, when a wire rope is detected to be faulty, workers need to determine the specific damaged point of the wire rope to take appropriate repair measures, such as cutting off the damaged part, reconnecting or replacing a new wire rope, etc. In a complex industrial environment, the wire rope may be hundreds of meters long, and it is difficult for workers to find the damaged point of the wire rope, which in turn affects the subsequent repair measures for the wire rope.

[0045] Therefore, in order to avoid the above problems, when the present embodiment is used, the support frame 1 is placed at the mine mouth, and the steel wire rope is passed through the circular hole 7, the through hole 26, the mounting ring 8, and the housing 30. Moreover, when the steel wire rope passes through the center of the mounting ring 8, it will contact with multiple movable pulleys 16 at the same time, and multiple movable pulleys 16 will move radially at the same time. Moreover, under the cooperation of the adjusting connecting rod 13, the connecting block 14, and the sliding rod 2 15, the adjusting ring 11 will move upward, and under the action of the spring 10, the movable pulley 16 is in close contact with the surface of the steel wire rope. Moreover, since the detection rod 17 has a certain length, the detection rod 17 always extends from one fixed plate 24 to the top of another fixed plate 24, and then according to the height of the pressure rod 23, the electric push rod 19 is used to drive the connecting plate 20 to move downward until the pressure sensor 22 is in contact with the end of the pressure rod 23, and the pressure value detected by the pressure sensor 22 is zero at this time.

[0046] During the up and down movement of the wire rope, if the wire rope is broken, the broken wire area will bulge, and its bulge position will contact the movable pulley 16 or the detection rod 17, so that the movable pulley 16 or the detection rod 17 moves, and when the movable pulley 16 or the detection rod 17 at any position moves, the adjusting ring 11 will move. Therefore, no matter where the wire rope is bulged, the adjusting ring 11 will rise. When the pressure rod 23 squeezes the pressure sensor 22, the pressure sensor 22 transmits the pressure signal to the controller, and the controller makes the buzzer 21 sound, so as to remind the surrounding personnel that the wire rope has a fault and needs to take measures in time, which is conducive to improving the construction safety. In addition, with the cooperation of multiple movable pulleys 16 and the detection rod 17, the wire rope can be surrounded. No matter where the wire rope is bulged due to the broken wire, the pressure sensor 22 will detect the pressure signal, thereby avoiding the situation of detection blind spots due to the gap between the movable pulleys 16, and further improving the comprehensiveness of the detection.

[0047] When the wire rope is detected to be broken, according to the moving direction and speed of the wire rope, when the broken wire area of ​​the wire rope is in the inner cavity of the shell 30, the pump body 5 at the corresponding position is started and the paint in the paint box 4 is extracted, and sprayed onto the surface of the wire rope through the connecting pipe 6, the annular pipe 28, and the nozzle 29. Since the number of nozzles 29 is set to be multiple, the broken wire area of ​​the wire rope will be sprayed with paint all around. The staff can quickly find the damaged point of the wire rope by observing the position of the paint on the surface of the wire rope, so as to take subsequent repair measures for the wire rope, thereby improving the repair efficiency. In addition, the paint can be added to the paint box 4 through the feeding port 12;

[0048] Furthermore, when the wind is strong in the working environment of the entire device, the paint sprayed by the nozzle 29 may splash to positions other than the damaged point of the wire rope under the action of the wind, thereby causing the paint to adhere to the non-damaged point of the wire rope. When workers are looking for the damaged point, they are easily confused. In order to avoid this situation, when the damaged point of the wire rope is inside the shell 30, the electric push rod 231 drives the adjusting ring 233 to move upward, and the multiple sliding rods 234 35 can be moved radially at the same time under the action of the multiple connecting rods 232, so that the shielding cloth 25 is stretched. Since the shielding cloth 25 has a certain elasticity, the size of the through hole 26 will change with the movement of the stretching rod 27 until the wall of the through hole 26 fits the surface of the wire rope. At this time, the sprayed paint will only be concentrated in the cavity formed by the shell 30 and the shielding cloth 25, and will not splash to the surrounding area, thereby avoiding the damage caused by The working environment of the device is windy, and the paint sprayed by the nozzle 29 splashes to positions other than the damaged point of the wire rope under the action of wind, causing confusion for workers when looking for the damaged point of the wire rope. In addition, since paint will also adhere to the edge of the through hole 26 of the shielding cloth 25, if the through hole 26 is always in contact with the wire rope, then the friction between the shielding cloth 25 and the wire rope will cause the surface of the wire rope to be stained with paint in many places, which will still affect the workers' search for the damaged point. Therefore, in order to avoid this situation, after the damaged point is sprayed with paint, multiple stretching rods 27 are driven to move simultaneously again to enlarge the through hole 26 and move it away from the wire rope. This can avoid the situation where the paint at the through hole 26 is stained to various positions on the surface of the wire rope due to the shielding cloth 25 always being in contact with the wire rope, which is further conducive to the workers' search for the damaged point of the wire rope.

[0049] In this embodiment, Figure 1 As shown, a plurality of fastening screws 3 are provided on the base 2 .

[0050] Specifically, when the base 2 is placed at the mine entrance, the base 2 is fixed by fastening screws 3 that penetrate into the soil layer, thereby ensuring the stability of the entire device during operation.

[0051] Working principle: When the base 2 is placed at the mine mouth, the base 2 is fixed by fastening the screws 3 through the soil layer, and the wire rope passes through the circular hole 7, the through hole 26, the mounting ring 8, and the housing 30. When the wire rope passes through the center of the mounting ring 8, it will contact with multiple movable pulleys 16 at the same time. Multiple movable pulleys 16 move radially at the same time. In addition, with the cooperation of the adjusting connecting rod 13, the connecting block 14, and the sliding rod 2 15, the adjusting ring 11 will move upward, and under the action of the spring 10, the movable pulley 16 is in close contact with the surface of the wire rope. In addition, since the detection rod 17 has a certain length, the detection rod 17 always moves from one The fixed plate 24 extends to the top of another fixed plate 24, and then according to the height of the pressure rod 23, the electric push rod 19 is used to drive the connecting plate 20 to move downward until the pressure sensor 22 is in contact with the end of the pressure rod 23, and the pressure value detected by the pressure sensor 22 is zero at this time; during the up and down movement of the wire rope, if the wire rope is broken, the broken wire area will bulge, and its bulging position will contact the movable pulley 16 or the detection rod 17, so that the movable pulley 16 or the detection rod 17 moves, and when the movable pulley 16 or the detection rod 17 at any position moves, the adjusting ring 11 will move, so no matter which position of the wire rope is When a bulge appears at each position, the adjusting ring 11 will rise. When the pressure rod 23 squeezes the pressure sensor 22, the pressure sensor 22 transmits a pressure signal to the controller, and the controller sounds the buzzer 21 to remind the surrounding personnel that the wire rope has a fault and that measures need to be taken in time, which is beneficial to improving construction safety. In addition, with the cooperation of multiple movable pulleys 16 and detection rods 17, the wire rope can be surrounded. No matter which position of the wire rope has a bulge due to broken wire, the pressure sensor 22 will detect the pressure signal, thereby avoiding the situation of detection blind spots due to gaps between the movable pulleys 16, further improving the detection safety. Comprehensiveness; when the wire rope is detected to be broken, according to the moving direction and speed of the wire rope, when the broken wire area of ​​the wire rope is in the inner cavity of the shell 30, the pump body 5 at the corresponding position is started and the paint in the paint box 4 is extracted, and sprayed onto the surface of the wire rope through the connecting pipe 6, the annular pipe 28, and the nozzle 29. Since the number of nozzles 29 is set to be multiple, the broken wire area of ​​the wire rope will be sprayed with paint all around. The staff can quickly find the damaged point of the wire rope by observing the position of the paint on the surface of the wire rope, so as to take subsequent repair measures for the wire rope, thereby improving the repair efficiency. In addition, the paint can be added to the paint box 4 through the feeding port 12;Furthermore, when the wind is strong in the working environment of the entire device, the paint sprayed by the nozzle 29 may splash to positions other than the damaged point of the wire rope under the action of the wind, thereby causing the paint to adhere to the non-damaged point of the wire rope. When workers are looking for the damaged point, they are easily confused. In order to avoid this situation, when the damaged point of the wire rope is inside the shell 30, the electric push rod 231 drives the adjusting ring 233 to move upward, and the multiple sliding rods 234 35 can be moved radially at the same time under the action of the multiple connecting rods 232, so that the shielding cloth 25 is stretched. Since the shielding cloth 25 has a certain elasticity, the size of the through hole 26 will change with the movement of the stretching rod 27 until the wall of the through hole 26 fits the surface of the wire rope. At this time, the sprayed paint will only be concentrated in the cavity formed by the shell 30 and the shielding cloth 25, and will not splash to the surrounding area, thereby avoiding the damage caused by The working environment of the device is windy, and the paint sprayed by the nozzle 29 splashes to positions other than the damaged point of the wire rope under the action of wind, causing confusion when workers are looking for the damaged point of the wire rope.
