Description

Technical Field

[0001] The invention relates to the technical field of car tipping machine hooks, and in particular to a car tipping machine vehicle hook failure detection device and a detection method thereof. Background Art

[0002] The car tipping machine system is a loading and unloading machine that can flip or tilt train vehicles to unload materials. It is suitable for ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power. The car tipping machine unloading system consists of a car tipping machine, a car pusher, a car shifter, a car transfer platform, and vehicles. Train vehicles are connected by couplers, which are functional components located at both ends of the vehicle and are used to connect the vehicles to each other. Because the car tipping machine will flip the vehicle and its coupler about 180 degrees during the unloading process, under this working condition, there is a certain probability that the locking pin of a specific model of coupler will be lifted due to vibration or impact, resulting in the coupler being in an unlocked state. In this state, the coupler can be opened under the push of external force, resulting in the hidden danger of accidental unhooking of the coupler and separation of the vehicles. Abnormal unhooking of the coupler will cause the vehicle to separate. If it is not discovered in time, accidents such as slipping and collision will occur, which will seriously affect production safety and normal unloading order. Therefore, it is particularly important to be able to detect and stop the vehicle and alarm in time when the coupler is abnormally unhooked. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0034] The following will refer to the attached Figures 1 to 5 The present invention is described in detail with reference to embodiments.

[0035] Example 1

[0036] In general, the present invention relates to a vehicle hitch failure detection device for a dumper, such as Figure 2 As shown. It includes a coupler 1, a socket 101 opened on the coupler 1, a lifting pin 102 inserted into the socket 101, and a lifting chain 1021 with an end fixedly connected to the lifting pin 102. It should be understood that the adjacent train 6 carriages are connected through the coupler 1, and the lifting pin 102 is used to tightly connect the couplers 1 of the two carriages together. During the connection process, the lifting pin 102 ensures a firm connection between the carriages by inserting into the corresponding part of the coupler 1. This connection method can ensure that the carriages of the train 6 will not be accidentally separated during operation, and the lifting chain 1021 can fix the lifting pin 102 on the side wall of the carriage.

[0037] The detection device involved in the present invention includes a tension detection component arranged at the bottom of the coupler 1 for detecting the tension of the couplers 1 on both sides, a position detection component arranged at the socket 101 for detecting the position of the lifting pin 102, and a laser ranging sensor 4 arranged on the train 6 carriage; the train 6 carriage is provided with a processing module 7 which is respectively communicated with the tension detection component, the position detection component and the laser ranging sensor 4, and the head car of the train 6 is provided with a main control module 8 which is electrically connected to each processing module 7.

[0038] When there is or is about to be a coupling failure between the carriages, the tension between them will change. In this embodiment, the tension detection component can feed back the tension data of two adjacent train carriages 6 to the processing module 7 to determine whether there is an abnormal tension effect between the carriages, so that the staff can find the coupling failure problem in time. The position detection component can detect the position of the lifting pin 102 in the coupler 1, and the connection status of the coupler 1 can be checked through the position of the lifting pin 102, so that the operator can find the problem in time.

[0039] Among them, the laser ranging sensor 4 can detect the distance between the two carriages. The working principle of the laser ranging sensor 4 is based on the time-of-flight method. It first emits a laser pulse from a laser diode to the target. After being reflected by the target, part of the scattered light returns to the sensor receiver. By recording and processing the time from the emission of the light pulse to the return and reception, combined with the speed of light (about 3X10^8m / s), the distance of the target object can be calculated. In specific implementation, at least three ranging sensors 4 are set to make the distance measurement more accurate.

[0040] It should be noted that the processing module 7 is used to process the feedback data, and the main control module 8 is used to aggregate the data of each processing module 7, so that the operator can understand the situation between each car more intuitively.

[0041] The processing module 7 is preferably an RS485 to Ethernet serial port server, which is connected to external devices through a serial port interface. These devices can be various sensors, controllers, debugging tools, etc. Through the serial port server, users can collect and process device data, saving manpower and time costs. The main control module 8 is preferably a Siemens smart series PLC, which is a programmable logic controller, an electronic system for digital operation, designed for use in industrial environments. It uses a type of programmable memory for its internal storage program, executes user-oriented instructions such as logical operations, sequential control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital or analog input / output. The data of each processing module 7 can be stored, analyzed and processed.

[0042] It should be noted that after the coupling 1 fails to be disconnected, the traction force between them will change, and the tension detection component can detect the tension between them, such as Figure 3As shown, the tension detection component includes fixed arms 3 symmetrically arranged at the bottom of the left and right side couplers 1, connecting rods 301 movably connected to each fixed arm 3 and with ends close to each other, and sliding plates 302 movably connected to the ends close to the connecting rods 301, the sliding plates 302 are slidably arranged in the detection tube 306, fixed plates 304 are fixed between the sliding plates 302, and tension sensors 305 are fixed on the fixed plates 304, and the tension sensors 305 are connected to the sliding plates 302 on both sides respectively through tension springs 303; the tension sensors 305 are communicatively connected to the processing module 7.

[0043] In specific implementation, when the hooks 1 on both sides are disengaged, the fixed arm 3 will pull the connecting rods 301 on both sides, driving the sliding plates 302 on both sides to move relative to each other, and then the tension spring 303 is stretched, and the tension sensor 305 measures its data and transmits it to the processing module 7. It should be further explained that since shaking will occur when the disconnection fails, the movable connection can ensure the normal operation of the tension detection component when shaking occurs. In addition, when the carriage is disengaged, the tension spring 303 will break, thereby preventing damage to other components of the tension detection component, and the tension spring 303 can be replaced later.

[0044] Preferably, the fixed arm 3 and the connecting rod 301 , and the connecting rod 301 and the sliding plate 302 are movably connected via universal joints.

[0045] like Figures 2 to 5 As shown, the position detection component includes a mounting ring 2 in a circular ring shape and arranged at the position of the socket 101, the lifting pin 102 is slidably connected in the mounting ring 2, and mounting holes 201 are opened on two opposite sides of the mounting ring 2, and a displacement sensor 202 is arranged in the mounting hole 201.

[0046] In specific implementation, since the lifting pin 102 is inserted in the mounting ring 2, when an accident such as falling off occurs, the displacement sensors 202 on both sides can record the sliding data of the lifting pin 102 in the socket 101 door and feed it back to the processing module 7. The operator determines the position of the lifting pin 102 based on the sliding data.

[0047] In addition, a plurality of warning lights 5 are provided at intervals on the train carriage 6. When it is detected that the train carriage 6 has a risk of coupling failure and falling off, the warning lights 5 will flash to alert nearby staff.

[0048] Embodiment 2

[0049] The present invention also relates to a detection method for a vehicle hook failure detection device for a dumper, such as Figure 6 The detection method is applied to the vehicle hook failure detection device for a tipping machine in the above-mentioned embodiment 1, and the detection method comprises the following steps:

[0050] S1: The tension detection component detects the tension data of the hooks on both sides and transmits it to the processing module 7, and the distance sensor 4 detects the distance data between the distance measurement quantity and the carriage of the front train 6 and transmits it to the processing module 7;

[0051] S2: The processing module 7 calculates the ratio of the tension data to the distance data, and transmits the data to the main control module 8;

[0052] S3: The position detection component detects the position data of the lifting pin 102 in the socket 101 and transmits the data to the processing module 7, and the processing module 7 transmits the data to the main control module 8;

[0053] S4: The main control module 8 determines whether the ratio of the tension data to the distance data in S2 is within a preset threshold value, and determines whether the coupler 1 is in a disengaged state or a semi-disengaged state in combination with the position data of the lifting pin 102 in the socket 101 in S3;

[0054] S5: According to the judgment of the main control module 8, if the train 6 is in a disengaged state or a semi-disengaged state, the train 6 stops running.

[0055] It should be noted that due to the complexity of on-site mining, calculating the ratio of tension data and distance data can better judge the situation between carriages and reduce misjudgment.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
