Description
Technical Field
[0001] This application relates to the field of mining equipment technology, and in particular to a wireless transmission skip anti-collision protection device. Background Technology
[0002] In the main shaft hoisting system of a mine, the skip is the core equipment for ore hoisting. It is used to directly load useful minerals, waste rock or gangue. There are two types: one for inclined shafts and one for vertical shafts. The main shaft skip is further divided into single-rope skip and multi-rope skip according to the type of hoist. According to the unloading method, it is divided into bottom unloading type and tipping type for vertical shafts; and rear unloading type and tipping type for inclined shafts.
[0003] The current method of checking the status of skip hooks relies heavily on manual visual inspection. However, if workers lack experience or make misjudgments, the hooks may not be properly engaged, which could cause the skip hooks to collide with the main shaft guide beam during the lowering of the main shaft skip. This could damage the skip, guide beam, and wire rope, leading to malfunctions, shutdowns, and disruptions to normal production.
[0004] Therefore, this application provides a wireless transmission bucket anti-collision protection device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a wireless transmission skip anti-collision protection device, which overcomes the deficiencies of existing technologies. It aims to solve the problem that the detection of the skip hook status currently relies heavily on manual visual confirmation. However, if the workers lack experience or make misjudgments, the hook may not be properly engaged, which could cause the skip hook to collide with the main shaft guide beam during the main shaft skip descent, resulting in damage to the skip, guide beam, and wire rope, leading to malfunctions, shutdowns, and disruptions to normal production.
[0006] To achieve the above objectives, this application provides the following technical solution: a wireless transmission skip anti-collision protection device, comprising a lifting mechanism, a skip, and two sets of guide rails. Four sets of traveling wheels are fixedly installed at the bottom of the skip. Two sets of traveling wheels on the same side are rotatably connected to the sliding ends of the corresponding guide rails. A discharge box is hinged to the bottom of the skip. Rotary shafts are fixedly installed on both sides of the discharge box. Hooks are rotatably connected to the outer surface of the rotating shafts. A socket matching the two sets of hooks is fixedly installed at the bottom of the skip. A bracket is fixedly installed at the bottom of the socket. A magnetic proximity switch is fixedly installed at the bottom of the bracket. A controller is fixedly installed on one side of the skip. A wireless receiver is fixedly installed on the top of the controller. A wireless transmitter is fixedly installed on the top of the controller, located on one side of the wireless receiver. The controller is electrically connected to the lifting mechanism, the magnetic proximity switch, the wireless receiver, and the wireless transmitter.
[0007] By adopting the above technical solution, before the skip is lowered, the hook is rotated to connect the hook to the socket. The hook is made of magnet, and the magnetic proximity switch is model MCS-500. When the hook is rotated into place, it will contact the detection end of the magnetic proximity switch. Then, the controller receives the closed signal output by the magnetic proximity switch through the wireless receiver, and then controls the lifting mechanism to drive the skip to move. Conversely, if the hook is not engaged, the magnetic proximity switch will not output a signal. At this time, the lifting mechanism is in standby mode. The magnetic proximity switch replaces manual inspection, avoiding missed inspections and misjudgments caused by insufficient experience or fatigue. This helps to ensure the safety of the skip during the lowering process, reduces the possibility of collisions, and improves the continuity of production.
[0008] As a preferred technical solution of this application, the lifting mechanism includes a reciprocating motor located on one side of the skip. A take-up and release roller is fixedly installed at the output end of the reciprocating motor. Two sets of steel wire ropes are wound and connected to the outer surface of the take-up and release rollers. The ends of the two sets of steel wire ropes away from the take-up and release rollers are fixedly installed to the skip. A relay is electrically connected to one side of the reciprocating motor, and the relay is electrically connected to the controller.
[0009] By adopting the above technical solution, if the hook is not properly engaged, the magnetic proximity switch will not output a signal. The controller will control the reciprocating motor to cut off the power supply through the relay. After the hook is properly engaged, the relay will control the reciprocating motor to start. The reciprocating motor will drive the take-up and unwinding rollers to unwind the wire rope, so that the skip will be lowered under the action of the two sets of wire ropes. During the lowering process, the skip will slide in the corresponding guide rails through the four sets of traveling wheels, which is conducive to the stability of the skip during the lowering.
[0010] As a preferred technical solution of this application, the two sets of sockets have grooves on the side away from the bucket, and an indicator light is fixedly installed on one side of the socket in the groove. The indicator light is electrically connected to the magnetic proximity switch.
[0011] By adopting the above technical solution, when the hook is properly engaged, the indicator light receives the closing signal of the magnetic proximity switch and displays green. Conversely, when the hook is not properly engaged, the indicator light displays red. This helps staff to judge the status of the hook by the color of the indicator light, thus improving its practicality during use.
[0012] As a preferred technical solution of this application, load sensors are fixedly installed at the connection points of the two sets of wire ropes and the skip, and the load sensors are electrically connected to the controller.
[0013] By adopting the above technical solution, the tension on the wire rope is monitored in real time by a load sensor. When the controller detects that the tension on the wire rope is too heavy, it may be due to overload in the skip. At this time, the controller automatically cuts off the power to the reciprocating motor through a relay and transmits the signal to the receiving end of the wellhead control box through a wireless transmitter to remind the staff to solve the problem in time. This further improves the safety of the skip during the lowering process, reduces the possibility of collisions, and improves the continuity of production.
[0014] As a preferred technical solution of this application, an adjustment handle is fixedly installed on the side of the hook away from the unloading box.
[0015] By adopting the above technical solution, the adjustment provides a convenient hand action point when adjusting the hook, thus improving the convenience of hook adjustment.
[0016] As a preferred embodiment of this application, a speaker is fixedly installed on one side of the controller, the speaker is located between the wireless receiver and the wireless transmitter, and the speaker is electrically connected to the wireless receiver.
[0017] By adopting the above technical solution, when the controller receives a signal that the hook has not been properly engaged for a long time, or that the skip has been overloaded for a long time, or that the lifting mechanism has malfunctioned, the speaker will emit a buzzer, which helps to attract the operator's attention, remind the operator to solve the problem in a timely manner, and further improves the safety during use.
[0018] As a preferred embodiment of this application, a battery compartment is fixedly installed at the bottom of the controller, and a storage battery is fixedly installed inside the battery compartment.
[0019] By adopting the above technical solution, the small electrical devices of this device are powered by the battery in the battery compartment, which improves the flexibility of the device during use.
[0020] As a preferred technical solution of this application, a waterproof protective shell is fixedly installed on one side of the bucket on the outer periphery of the controller, and a light-transmitting glass is fixedly installed on the front surface of the waterproof protective shell.
[0021] By adopting the above technical solution, the combination of transparent glass and waterproof protective shell ensures the wireless signal penetration of the wireless receiver and wireless transmitter while preventing dust from entering, thereby reducing the number of maintenance required.
[0022] The beneficial effects of this application are: 1. Before lowering the skip, the hook is rotated to connect to the socket. The hook is made of magnet. When the hook is rotated to the correct position, it contacts the detection end of the magnetic proximity switch. The controller then receives the closed signal output by the magnetic proximity switch through the wireless receiver and controls the lifting mechanism to drive the skip to move. Conversely, if the hook is not properly engaged, the magnetic proximity switch will not output a signal. At this time, the lifting mechanism is in standby mode. The magnetic proximity switch replaces manual inspection, avoiding missed inspections and misjudgments caused by insufficient experience or fatigue. This helps ensure the safety of the skip during the lowering process, reduces the possibility of collisions, and improves the continuity of production.
[0023] 2. If the hook is not properly engaged, the magnetic proximity switch will not output a signal. The controller will control the reciprocating motor to cut off the power supply via a relay. After the hook is properly engaged, the relay will start the reciprocating motor, which will drive the take-up and unwind rollers to unwind the wire rope. This will allow the skip to be lowered under the action of the two sets of wire ropes. During the lowering process, the skip will slide within the corresponding guide rails via four sets of wheels, which will help ensure the stability of the skip during lowering.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Reference Figure 1-5 A wireless transmission skip anti-collision protection device includes a lifting mechanism 1, a skip 2, and two sets of guide rails 3. Four sets of traveling wheels 4 are fixedly installed at the bottom of the skip 2. Two sets of traveling wheels 4 on the same side are rotatably connected to the sliding ends of the corresponding guide rails 3. A discharge box 5 is hinged to the bottom of the skip 2. Rotating shafts 6 are fixedly installed on both sides of the discharge box 5. Hooks 7 are rotatably connected to the outer surface of the rotating shafts 6. A socket 9 matching the two sets of hooks 7 is fixedly installed at the bottom of the skip 2. A bracket 10 is fixedly installed at the bottom of the socket 9. A magnetic connector is fixedly installed at the bottom of the bracket 10. A proximity switch 11 is located on one side of the bucket 2. A controller 12 is fixedly installed on the top of the controller 12. A wireless receiver 13 is fixedly installed on the top of the controller 12, and a wireless transmitter 14 is fixedly installed on the top of the controller 12, located to the side of the wireless receiver 13. The controller 12 is electrically connected to the lifting mechanism 1, the magnetic proximity switch 11, the wireless receiver 13, and the wireless transmitter 14. Two sets of sockets 9 have grooves 15 on the side away from the bucket 2. An indicator light 16 is fixedly installed on one side of the socket 9, located in the groove 15. The indicator light 16 is electrically connected to the magnetic proximity switch 11.
[0028] Before lowering the skip 2, the hook 7 is rotated to connect to the socket 9. The hook 7 is made of magnet. When the hook 7 is rotated into position, it will contact the detection end of the magnetic proximity switch 11. Then, the controller 12 receives the closed signal output by the magnetic proximity switch 11 through the wireless receiver 13, and then controls the lifting mechanism 1 to drive the skip 2 to move. Conversely, if the hook 7 is not properly engaged, the magnetic proximity switch 11 will not output a signal. At this time, the lifting mechanism 1 is in standby mode. The magnetic proximity switch 11 replaces manual inspection, avoiding missed inspections and misjudgments caused by insufficient experience or fatigue. This helps to ensure the safety of the skip 2 during the lowering process, reduces the possibility of collisions, and improves the continuity of production. When the hook 7 is properly engaged, the indicator light 16 receives the closed signal from the magnetic proximity switch 11 and displays green. Conversely, when the hook 7 is not properly engaged, the indicator light 16 displays red. This allows the staff to judge the status of the hook 7 by the color of the indicator light 16, improving the practicality of use.
[0029] Reference Figure 1-3The lifting mechanism 1 includes a reciprocating motor 101, which is located on one side of the skip 2. A take-up roller 102 is fixedly installed at the output end of the reciprocating motor 101. Two sets of steel wire ropes 103 are wound and connected to the outer surface of the take-up roller 102. The ends of the two sets of steel wire ropes 103 away from the take-up roller 102 are fixedly installed to the skip 2. A relay 104 is electrically connected to one side of the reciprocating motor 101. The relay 104 is electrically connected to the controller 12. A load sensor 17 is fixedly installed at the connection points of the two sets of steel wire ropes 103 and the skip 2. The load sensor 17 is electrically connected to the controller 12. If hook 7 is not properly engaged, magnetic proximity switch 11 will not output a signal, and controller 12 will control reciprocating motor 101 to cut off the power supply via relay 104. After hook 7 is properly engaged, relay 104 will control reciprocating motor 101 to start, and reciprocating motor 101 will drive take-up and unwind rollers 102 to unwind wire rope 103, thereby lowering skip 2 under the action of two sets of wire rope 103. During the lowering process, skip 2 slides in the corresponding guide rails 3 through four sets of traveling wheels 4, which helps to ensure the smoothness of skip 2 during lowering. The controller 12 monitors the tension on the wire rope 103 in real time through the load sensor 17. When the controller 12 detects that the tension on the wire rope 103 is too heavy, it may be due to overload in the skip 2. At this time, the controller 12 automatically cuts off the power to the reciprocating motor 101 through the relay 104 and transmits the signal to the receiving end of the wellhead control box through the wireless transmitter 14 to remind the staff to solve the problem in time, thereby further improving the safety of the skip 2 during the lowering process, reducing the possibility of collisions, and improving the continuity of production.
[0030] Reference Figure 3-5 An adjustment handle 21 is fixedly installed on the side of the hook 7 away from the unloading box 5; a battery compartment 19 is fixedly installed at the bottom of the controller 12, and a storage battery is fixedly installed inside the battery compartment 19; the adjustment handle 21 provides a hand action point for adjusting the hook 7, which improves the convenience of adjusting the hook 7; the storage battery in the battery compartment 19 supplies power to the small electrical equipment of this device, which improves the flexibility of the device when it is used.
[0031] Reference Figure 2-4A speaker 18 is fixedly installed on one side of the controller 12, located between the wireless receiver 13 and the wireless transmitter 14, and electrically connected to the wireless receiver 13. A waterproof protective shell 20 is fixedly installed on one side of the skip 2 around the controller 12, and a translucent glass is fixedly installed on the front surface of the waterproof protective shell 20. When the controller 12 receives a signal that the hook 7 has not been properly engaged for a long time, or that the skip 2 has been overloaded for a long time, or that the lifting mechanism 1 has malfunctioned, the speaker 18 will emit a buzzer, which helps to attract the operator's attention and remind the operator to solve the problem in time, further improving the safety during use. The cooperation between the translucent glass and the waterproof protective shell 20 ensures the wireless signal penetration of the wireless receiver 13 and the wireless transmitter 14, while preventing dust from entering, thereby reducing the number of maintenance operations.
[0032] Working principle: Before lowering the skip 2, the hook 7 is rotated to connect to the socket 9. The hook 7 is made of magnet. When the hook 7 is rotated to the correct position, it contacts the detection end of the magnetic proximity switch 11. Then, the controller 12 receives the closed signal output by the magnetic proximity switch 11 through the wireless receiver 13, and then controls the lifting mechanism 1 to drive the skip 2 to move. Conversely, if the hook 7 is not properly engaged, the magnetic proximity switch 11 will not output a signal. At this time, the lifting mechanism 1 is in standby mode. The magnetic proximity switch 11 replaces manual inspection, avoiding missed inspections and misjudgments caused by insufficient experience or fatigue, which helps to ensure the skip's operation. The safety of skip 2 during the lowering process is improved by reducing the possibility of collisions and increasing the continuity of production. If the hook 7 is not properly engaged, the magnetic proximity switch 11 will not output a signal. The controller 12 will control the reciprocating motor 101 to cut off the power supply through the relay 104. After the hook 7 is properly engaged, the relay 104 will control the reciprocating motor 101 to start. The reciprocating motor 101 will drive the take-up and unwinding rollers 102 to unwind the wire rope 103, so that the skip 2 will be lowered under the action of the two sets of wire ropes 103. During the lowering process, the skip 2 will slide in the corresponding guide rails 3 through the four sets of traveling wheels 4, which is conducive to the stability of the skip 2 during the lowering process. When the hook 7 is properly engaged, the indicator light 16 receives the closing signal from the magnetic proximity switch 11 and displays green. Conversely, when the hook 7 is not properly engaged, the indicator light 16 displays red. This allows the operator to judge the status of the hook 7 by the color of the indicator light 16, improving its practicality. The load sensor 17 monitors the tension on the wire rope 103 in real time. When the controller 12 detects that the tension on the wire rope 103 is too heavy, it may indicate that the skip 2 is overloaded. At this time, the controller 12 automatically cuts off the power to the reciprocating motor 101 through the relay 104 and transmits the signal to the receiving end of the wellhead control box through the wireless transmitter 14 to remind the operator to resolve the issue in time. This further improves the safety of the skip 2 during the lowering process, reduces the possibility of collisions, and improves the continuity of production. Meanwhile, by adjusting handle 21, a hand action point is provided for adjusting hook 7, which improves the convenience of adjusting hook 7; when controller 12 receives a signal that hook 7 has not been properly engaged for a long time, or skip 2 has been overloaded for a long time, or lifting mechanism 1 has an abnormal signal, speaker 18 will sound a buzzer, which helps to attract the operator's attention, remind the operator to solve the problem in time, and further improve the safety during use. In addition, the small electrical devices of this device are powered by the battery in the battery compartment 19, which improves the flexibility of the device during use; the combination of the light-transmitting glass and the waterproof protective shell 20 ensures the wireless signal penetration of the wireless receiver 13 and the wireless transmitter 14, while preventing dust from entering, thereby reducing the number of maintenance times.
