Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, specifically relating to an automatic unhooking device for vehicles. Background Technology

[0002] In vehicle traction or material transportation, the hooking and unhooking operations of car couplers generally rely on manual labor, which poses problems such as high personal risk, high labor intensity, and low efficiency. In order to improve the level of automation, existing technologies have developed automatic unhooking devices that use pneumatic, hydraulic, or electric push rods as power sources.

[0003] Patent application number 202422636089.2 proposes an automatic locomotive uncoupling device, comprising: a base, a drive structure, a rotating arm, a lifting rod, and a control structure, which solves the problems of complex structure and poor versatility of existing automatic locomotive uncoupling devices.

[0004] However, in the existing technology, after the uncoupling is completed, the process of resetting and locking the locking plate relies on the impact force generated by the collision between the two couplers when they are coupled to push the locking plate back to the locking position. This method has limitations. It is easy for the locking plate to fail to reset due to insufficient impact force, resulting in locking failure. Moreover, the staff cannot detect this in time, which can easily affect the safety of the operation. Utility Model Content

[0005] Based on the above-mentioned technical problems, the purpose of this utility model is to provide an automatic unhooking device for vehicles. This device uses the gravitational potential energy of the counterweight to actively drive the locking plate to fall, so that the locking pin is reset to the locked state, reducing the situation where the locking plate is not reset properly. By using monitoring sensors and monitoring points in conjunction, the state of the locking plate can be monitored so that the operator can determine whether the locking plate is in the locked state.

[0006] The specific technical solution is as follows: An automatic unhooking device for vehicles includes: a linkage assembly, mounting components, an electric push rod, a hook chain, a locking plate, counterweights, a monitoring sensor, and a monitoring point. The linkage assembly includes a first connecting rod, a horizontal connecting rod, and a second connecting rod. The two ends of the horizontal connecting rod are respectively connected to the first and second connecting rods, and both the first and second connecting rods are provided with connecting seats. Two mounting components are respectively fixed to both sides of the vehicle frame, and the horizontal connecting rod is rotatably connected to the mounting components. The electric push rod is hinged to a support seat, which is located on one side of the vehicle frame, and the telescopic end of the electric push rod is hinged to the connecting seat of the first connecting rod. The connecting seat of the second connecting rod is hinged to one end of the hook chain, and the other end of the hook chain is hinged to the locking plate, and the bottom of the locking plate is connected to the locking pin of the vehicle hook. Counterweights are provided on both sides of the front end of the locking plate. A monitoring point is provided on one side of the locking plate, and a monitoring sensor is located on one side of the vehicle hook, with the monitoring sensor and the monitoring point being opposite each other.

[0007] In addition, the automatic unhooking device for vehicles provided by this utility model may also have the following additional technical features: The above technical solution also includes: two card slots and two card blocks; the two card slots are respectively set on the top of the coupler, and the two card blocks are respectively connected to the two sides of the bottom of the lock plate, and the card blocks are embedded in the card slots.

[0008] The above technical solution also includes: a torsion spring, a hook head positioning pin, and a hook tongue positioning pin; the hook head positioning pin and the hook tongue positioning pin are respectively set on the hook head and the hook tongue of the coupler, the torsion spring is installed on the coupler, and the two ends of the torsion spring are respectively connected to the hook head positioning pin and the hook tongue positioning pin.

[0009] The above technical solution also includes: a mounting base, a first proximity switch, and a second proximity switch; the mounting base is mounted on the coupler and located above the torsion spring; the first proximity switch is disposed on the mounting base, and the second proximity switch is disposed on the hook tongue of the coupler.

[0010] The above technical solution also includes: an alarm, which is installed on the mounting base.

[0011] In the above technical solution, both the first connecting rod and the second connecting rod are set perpendicular to the horizontal connecting rod.

[0012] The advantages of this automatic unhooking device for vehicles compared with the prior art are as follows: 1. The electric push rod is used as the power source, and the power is transmitted to the hook chain through the linkage assembly, so that the locking plate falls or is lifted, thereby realizing the purpose of automatic hook unhooking.

[0013] 2. By setting counterweights on both sides of the front end of the locking plate, when the electric push rod retracts to control the locking plate to fall, the gravitational potential energy of the counterweights actively drives the locking plate to fall, so that the locking pin returns to the locked state. This reduces the problem of the locking plate not returning to the correct position and failing to lock due to insufficient collision force when the two couplers are connected. In addition, by using monitoring sensors and monitoring points in conjunction, the status of the locking plate can be monitored so that the operator can determine whether the locking plate is in the locked state. When an abnormality occurs, the alarm will sound in time to remind the operator to pay attention.

[0014] 3. The coordinated use of counterweights, slots, and blocks enhances the stability of the lock plate, preventing abnormal swaying caused by vehicle vibration and thus avoiding accidental disengagement.

[0015] 4. The first and second proximity switches installed on the coupler are used to monitor in real time whether the coupler is locked or disengaged. Attached Figure Description

Detailed Implementation

[0017] The following are specific implementation cases and appendices. Figure 1-6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0018] An automatic unhooking device for vehicles, such as Figure 1-6 As shown, it includes: a linkage assembly, mounting parts 13, an electric push rod 14, a hook chain 15, a locking plate 16, a counterweight 17, a monitoring sensor 18, and a monitoring point 19; the linkage assembly includes a first connecting rod 10, a horizontal connecting rod 11, and a second connecting rod 12, with both ends of the horizontal connecting rod 11 connected to the first connecting rod 10 and the second connecting rod 12 respectively, and both the first connecting rod 10 and the second connecting rod 12 are provided with connecting seats; two mounting parts 13 are respectively fixed to both sides of the frame, and the horizontal connecting rod 11 is rotatably connected to the mounting parts 13; the electric push rod... Rod 14 is hinged to support base, which is located on one side of the frame. The telescopic end of electric push rod 14 is hinged to the connecting seat of first connecting rod 10. The connecting seat of second connecting rod 12 is hinged to one end of hook chain 15, and the other end of hook chain 15 is hinged to locking plate 16. The bottom of locking plate 16 is connected to the locking pin of coupler 29. Counterweights 17 are provided on both sides of the front end of locking plate 16. A monitoring point 19 is provided on one side of locking plate 16. A monitoring sensor 18 is located on one side of coupler 29, and the monitoring sensor 18 and monitoring point 19 are positioned opposite each other.

[0019] With the above structure, when unhooking is required, the electric push rod 14 extends to push the first connecting rod 10 to rotate clockwise, and the horizontal connecting rod 11 drives the second connecting rod 12 to move synchronously, thereby pulling the hook chain 15 to lift the locking plate 16 upward, realizing the automatic unhooking operation of the coupler 29. When locking is required, the electric push rod 14 retracts to drive the first connecting rod 10 to rotate counterclockwise, and the second connecting rod 12 releases the pulling force on the hook chain 15. At this time, the counterweights 17 set on both sides of the front end of the locking plate 16 generate a downward force under the action of gravity. The gravitational potential energy of the counterweights 17 actively drives the locking plate 16 to fall, so that the locking pin is reset to the locked state. This reduces the problem of the locking plate 16 not being reset properly and locking failure due to insufficient collision force when the two couplers 29 are connected. In addition, the monitoring sensor 18 and monitoring point 19 are used in conjunction to monitor the state of the locking plate 16, so that the operator can determine whether the locking plate 16 is in the locked state, thereby improving the safety of operation.

[0020] When the locking plate 16 is in the locked position, the monitoring point 19 on the locking plate 16 is opposite to the monitoring sensor 18. When the monitoring sensor 18 detects the monitoring point 19, it transmits the signal to the controller. The controller determines that the coupler 29 is in the locked state and issues a locked state signal. If the locking plate 16 is not in the locked position, the monitoring point 19 is off the sensing area of ​​the monitoring sensor 18, and the monitoring sensor 18 cannot identify the position of the monitoring point 19, then issues an unlocked state signal so that the operator can handle it in time.

[0021] In an embodiment of this utility model, it further includes: two slots 20 and two blocks 21; the two slots 20 are respectively disposed on the top of the hook 29, and the two blocks 21 are respectively connected to the two sides of the bottom of the locking piece 16, and the blocks 21 are embedded in the slots 20.

[0022] With the cooperation of the slot 20 and the block 21, the position of the locking plate 16 is limited after the locking plate 16 is locked, so as to prevent the locking plate 16 from lateral displacement or swinging due to vehicle vibration, thereby preventing the locking plate 16 from accidentally disengaging.

[0023] In the embodiments of this utility model, it further includes: a torsion spring 22, a hook head positioning pin 23, and a hook tongue positioning pin 24; the hook head positioning pin 23 and the hook tongue positioning pin 24 are respectively disposed on the hook head and the hook tongue of the car coupler 29, the torsion spring 22 is installed on the car coupler 29, and the two ends of the torsion spring 22 are respectively connected to the hook head positioning pin 23 and the hook tongue positioning pin 24.

[0024] By connecting the two ends of the torsion spring 22 to the hook head positioning pin 23 and the hook tongue positioning pin 24 respectively, the torsion spring 22 plays an auxiliary role, helping the hook 29 to more easily reach the unlocked or fully open state.

[0025] In an embodiment of this utility model, it further includes: a mounting base 25, a first proximity switch 26, and a second proximity switch 27; the mounting base 25 is mounted on the coupler 29 and located above the torsion spring 22; the first proximity switch 26 is disposed on the mounting base 25, and the second proximity switch 27 is disposed on the hook tongue of the coupler 29.

[0026] By using the first proximity switch 26 and the second proximity switch 27 together, the opening or closing status of the hook tongue can be monitored in real time. When the electric push rod 14 is operated, it controls the coupler 29 to perform unhooking or hooking operations. When the first proximity switch 26 detects the position of the hook tongue, it sends a unhooking status signal to the controller; when the second proximity switch 27 detects the position of the hook tongue, it sends a hooking status signal to the controller, thereby realizing precise monitoring of the status of the coupler 29.

[0027] In an embodiment of this utility model, an alarm 28 is also included, which is mounted on the mounting base 25.

[0028] After the second proximity switch 27 detects the position of the hook tongue and sends a hook status signal, the locking plate 16 should be in the locked state. The monitoring sensor 18 monitors whether the position of the locking plate 16 is in the locked position and transmits the signal to the controller. When the controller receives the signal that the locking plate 16 is not in the locked position, it triggers the alarm 28 so that the operator knows that the locking has not been successful, thus facilitating the operator to handle the situation in a timely manner.

[0029] Specifically, by monitoring the locking status of the locking plate 16, the misjudgment of the hook tongue being closed but the locking pin not being locked is avoided.

[0030] In the embodiments of this utility model, the first connecting rod 10 and the second connecting rod 12 are both arranged perpendicularly to the horizontal connecting rod 11.

[0031] Since both the first connecting rod 10 and the second connecting rod 12 are perpendicular to the horizontal connecting rod 11 and are an integral structure, when the electric push rod 14 drives the first connecting rod 10 to rotate, the horizontal connecting rod 11 drives the second connecting rod 12 to move synchronously, ensuring a smooth unhooking action.

[0032] Implementation process: When unhooking is required, the electric push rod 14 extends to push the first connecting rod 10 to rotate clockwise, and the horizontal connecting rod 11 drives the second connecting rod 12 to move synchronously, thereby pulling the hook chain 15 to lift the locking plate 16 upward, realizing the automatic unhooking operation of the coupler 29; when locking is required, the electric push rod 14 retracts to drive the first connecting rod 10 to rotate counterclockwise, and the second connecting rod 12 releases the tension on the hook chain 15. At this time, the counterweights 17 set on both sides of the front end of the locking plate 16 generate a downward force under the action of gravity. The gravitational potential energy of the counterweights 17 actively drives the locking plate 16 to fall, so that the locking pin is reset to the locked state. This reduces the problem of the locking plate 16 not being reset properly and locking failure due to insufficient collision force when the two couplers 29 are connected. In addition, the monitoring sensor 18 and monitoring point 19 are used in conjunction to monitor the state of the locking plate 16, so that the operator can determine whether the locking plate 16 is in the locked state, thereby improving the safety of operation. When the locking plate 16 is in the locked position, the monitoring point 19 on the locking plate 16 is opposite to the monitoring sensor 18. When the monitoring sensor 18 detects the monitoring point 19, it transmits the signal to the controller. The controller determines that the coupler 29 is in the locked state and issues a locked state signal. If the locking plate 16 is not in the locked position, the monitoring point 19 is off the sensing area of ​​the monitoring sensor 18, and the monitoring sensor 18 cannot identify the position of the monitoring point 19, then issues an unlocked state signal so that the operator can handle it in time.
