Description

Technical Field

[0001] The utility model relates to the technical field of car tipper hooks, in particular to a car tipper hook failure detection device. Background Art

[0002] The car tipping machine system is a loading and unloading machine that can flip or tilt rail 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. The car shifter is used to shift the loaded vehicle into the car tipping machine, and the car tipping machine unloads the loaded vehicle. After the car tipping machine has finished unloading, the car shifter pushes the empty vehicle out of the car tipping machine and pushes it into the car transfer platform. The empty vehicle is transferred from the loaded vehicle line to the empty vehicle line via the car transfer platform, and then the car pusher pushes the empty vehicle out of the car transfer platform.

[0003] When pulling or pushing a vehicle, the car pusher or car pusher needs to first connect its own hook with the vehicle's hook. In the prior art, the hook on the vehicle is often not connected properly, and then the hook is unhooked and the vehicle slips during the process of pulling or pushing the vehicle by the car pusher or car pusher. This situation can easily cause damage to the vehicle and endanger production safety.

[0004] Therefore, the car shifter and car pusher are equipped with a detection device to check whether the car coupler is properly connected. Most of the existing detection devices monitor the lock tongue. If the lock tongue and the lock body in the coupler are separated, it cannot be detected by the detection device in the prior art, which may easily lead to accidents. In addition, when the existing Zhan-type coupler is used, when the two couplers are connected, a gap will appear between the couplers, and they are not tightly fitted. Once the train stops, slows down or accelerates, the two couplers will collide, causing the carriage to shake violently and affecting the detection effect of the lock tongue. Utility Model Content

[0045] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0046] The present embodiment relates to a car tipper hook failure detection device, which is used to detect the connection state of a first coupler 1 and a second coupler 2, wherein the first coupler 1 includes a first lock body 101 and a first lock tongue 102 that are pivotally connected, and the second coupler 2 includes a second lock body 201 and a second lock tongue 202 that are pivotally connected. The car tipper hook failure detection device includes a sensing mechanism 3 disposed on the first coupler 1, and a detection unit 4 connected to the first lock body 101.

[0047] The sensing mechanism 3 includes a sensing part 301 disposed at the locking end of the first locking tongue 102, a connecting plate 302 disposed on the pivot axis of the first locking tongue 102, and an elastic body 303 disposed between the connecting plate 302 and the first lock body 101. One end of the connecting plate 302 away from the elastic body 303 is connected to the sensing part 301. When the first coupler 1 and the second coupler 2 are locked, the elastic body 303 is in a compressed state, and when the first coupler 1 and the second coupler 2 are away from each other, the elastic body 303 is in a free state.

[0048] In addition, the detection unit 4 is provided with a first detection part 401 and a second detection part 402 that sense the sensing part 301. The first detection part 401 is provided above the sensing part 301 when the first lock tongue 102 is in a locked state, and the second detection part 402 is provided above the sensing part 301 when the first lock tongue 102 is in a free state. A third detection part 403 for detecting the second lock body 201 is also provided on the connecting plate 302, and the detection unit 4 further includes a fourth detection part 404 for detecting the second lock tongue 202 in a locked state.

[0049] The tipper hook failure detection device of this embodiment is provided with a sensing mechanism 3 on the first coupler 1, and a connecting plate 302 and an elastic body 303 on the pivot axis of the first locking tongue 102. When the first coupler 1 and the second coupler 2 are in a separated state, the sensing part 301 senses with the second detection part 402 to obtain separation state information. When the sensing part 301 pivots to the locked state with the first locking tongue 102, the sensing part 301 senses with the first detection part 401 to obtain the locked state information. At the same time, the fourth detection part 404 detects the position of the second locking tongue 202 to further verify the locked state information.

[0050] In addition, a third detection unit 403 is provided to detect the position of the second lock body 201 in the locked state, so as to prevent misjudgment of the connection relationship between the tipping machine and the train when the connection between the second lock body 201 and the second lock tongue 202 fails, thereby further ensuring the safety of the locked state.

[0051] Based on the above overall introduction, an exemplary structure of the tipper hook failure detection device of this embodiment is as follows: Figures 1 to 3 As shown, the first coupler 1 is used to be installed on a car shifter or a car pusher, and the second coupler 2 is used to be connected to a train car. A lock pin 10 for opening or closing the second lock tongue 202 is provided on the second coupler 2. When the two cars are docked, the lock pin 10 is in a lifted state, and the second lock tongue 202 opens toward the first lock tongue 102. When the first lock tongue 102 approaches the second lock tongue 202 and is cross-locked, the lock pin 10 falls, and the second lock tongue 202 is fixed and will not shake.

[0052] At this time, this embodiment, by arranging an elastic part above the pivot axis of the first locking tongue 102, connected to the locking tongue through the connecting plate 302, can increase the contact force between the first locking tongue 102 and the second lock body 201 in the locked state, thereby effectively alleviating the unstable operation of the vehicle caused by the swaying of the gap between the two couplers after the vehicle is connected, and by arranging a lock pin 10 on the second locking tongue 202, the second locking tongue 202 can form a restriction on the first locking tongue 102 to avoid separation during the driving of the carriage. In addition, by arranging the elastic body 303, when the first coupler 1 and the second coupler 2 are separated, the disengagement time of the second locking tongue 202 can be increased, the separation speed can be improved, and the shaking when the carriage is separated can be effectively avoided.

[0053] As a preferred implementation mode, Figures 1 to 3 As shown, the sensing part 301 includes a mounting base 3011 disposed on the first locking tongue 102, and a sensing column 3012 connected to the mounting base 3011. The connecting plate 302 is sleeved on the sensing column 3012, and the sensing column 3012 is inductively connected to the first detection part 401 and the second detection part 402.

[0054] Furthermore, if Figure 4 As shown, the mounting seat 3011 is provided with a threaded hole, the sensing column 3012 is threadedly connected to the mounting seat 3011, and a nut 3013 is also sleeved on the sensing column 3012, and the connecting plate 302 is arranged between the nut 3013 and the mounting seat 3011. After the nut 3013 is locked, the sensing column 3012 can be fixed on the mounting seat 3011. By setting the mounting seat 3011 on the lock tongue, the sensing column 3012 is threadedly connected to the mounting seat 3011, and the sensing column 3012 can be adjusted at any time to adapt to the sensing of the sensing column 3012 and the first detection part 401 and the second detection part 402, thereby improving the detection effect. When adjustment is needed, the height of the sensing column 3012 can be adjusted by loosening the nut 3013.

[0055] In this embodiment, Figures 1 to 4 As shown, the mounting seat 3011 adopts a circular columnar structure, and the mounting seat 3011 is detachably connected to the first locking tongue 102. Specifically, a protruding screw rod can be provided on the mounting seat 3011, and a screw hole adapted to the screw rod can be provided on the first locking tongue 102, and the mounting seat 3011 and the first locking tongue 102 are connected by threads. It is also possible to connect by means of plug-in connection, clamping connection, etc. By detachably connecting the mounting seat 3011 and the first locking tongue 102, the processing and replacement of the first locking tongue 102 are facilitated, and the convenience of use is improved.

[0056] Preferably, the elastic body 303 of this embodiment adopts a torsion spring. As a specific implementation, a round shaft 5 is connected above the pivot axis of the first locking tongue 102, and the elastic body 303 is sleeved on the outside of the round shaft 5. The round shaft 5 provides support for the elastic body 303. A pressing piece 6 for limiting the movement of the elastic body 303 is also provided above the round shaft 5. A bolt 7 for fixing the pressing piece 6 is connected to the round shaft 5. The bolt 7 and the pressing piece 6 are used to limit the upward and downward displacement of the elastic body 303.

[0057] Combination Figures 1 to 4 As shown, the connecting plate 302 is provided with a boss 8 connected to one end of the elastic body 303, and the first lock body 101 is provided with a boss 9, which is connected to the other end of the elastic body 303. The boss 8 and the boss 9 are respectively arranged on both sides of the elastic body 303, and are used to fix the two ends of the elastic body 303. The spring force of the torsion spring can be set according to the required abutment force.

[0058] like Figures 1 to 3As shown, the detection unit 4 also includes a bracket 405 and a fourth detection part 404 connected to the first lock body 101. The bracket 405 includes a vertical plate and a horizontal plate connected vertically. A fan-shaped mounting plate 406 is provided on the side of the horizontal plate away from the vertical plate. The fan-shaped mounting plate 406 is provided with a mounting hole for connecting the first detection part 401 and the second detection part 402. The horizontal plate is fixed to the side of the first lock body 101 through the vertical plate, and extends toward the locking position of the first lock tongue 102 and the second lock tongue 202. Such a configuration is simple in structure and easy to implement.

[0059] Furthermore, if Figure 1 , Figure 4 and Figure 6 As shown, the connecting plate 302 is provided with a connecting column 407 protruding upward, and a support plate 408 connected to the connecting column 407. When the first coupler 1 and the second coupler 2 are in a locked state, the support plate 408 extends toward the direction of the second lock body 201, and the third detection part 403 is linked to the connecting column 407. The connecting column 407 adopts a cylindrical structure, and the support plate 408 is a rectangular plate structure, and one end is sleeved on the connecting column 407 to form a "7" shape. The other end of the support plate 408 is provided with the third detection part 403. In the locked state, the third detection part 403 is arranged just above the second lock body 201, so that in the locked state, three detection parts are set to detect the lock tongues of the two couplers and the second lock body 201 at the same time, which can further ensure the detection accuracy, and the structure is simple and easy to implement.

[0060] Moreover, the third detection part 403 of the present embodiment is arranged on the connecting plate 302 and rotates with the connecting plate 302. When the first lock tongue 102 rotates to the locked state, the third detection part 403 is located above the second lock body 201. When the first lock tongue 102 rotates to the separated state, the third detection part 403 rotates to the outside of the second lock body 201. Such arrangement can also prevent the first coupler 1 and the second coupler 2 from interfering with or colliding with the third detection part 403 when they are locked with each other, and the third detection part 403 can also form a pre-detection signal of the second lock body 201 approaching the first lock body 101.

[0061] As a specific implementation, the first detection part 401 and the second detection part 402 use an inductive proximity switch, that is, a signal is obtained through the height distance between the inductive part 301 and the first detection part 401 and the second detection part 402, so as to obtain the connection relationship between the first coupler 1 and the second coupler 2. In addition, the third detection part 403 and the fourth detection part use a photoelectric proximity switch. The sensing ends of the third detection part 403 and the fourth detection part in this embodiment are facing the position of the coupler, specifically a photoelectric switch capable of collecting distance information. Not only can the position information of the second lock body 201 and the second lock tongue 202 be obtained, but also the distance information between the two in the height direction can be obtained, and whether the two lock tongues are misaligned and separated in height can be effectively detected, thereby further ensuring the detection effect.

[0062] Each detection switch in this embodiment is connected to the PLC of the detection system through a data line. The PLC can stop or start the operation of the tipping machine or the pushing machine and the train to avoid the danger caused by separation.

[0063] The above description is only a preferred embodiment of the present invention and is 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.
