Description

Technical Field

[0001] The utility model relates to the technical field of coupler straightening, in particular to a coupler straightening device. Background Art

[0002] In the prior art, a coupler is a vehicle component used to achieve the connection between a locomotive and a carriage or between carriages, transmit traction and impact force, and keep a certain distance between carriages. The coupler body is connected to the coupler frame installed at both ends of the carriage through a coupler pin. The coupler body takes the coupler pin as the center of the circle and can swing left and right within a certain range to adapt to the curved and turning railway transportation conditions. Most of the current railway systems use automatic couplers. The so-called automatic coupler is a coupler that can automatically complete the action of unhooking or hooking after the lifting rod of a coupler is lifted, and then the locomotive is used to pull the carriage open or collide with the hook of another carriage. Open carriages are often used for the transportation of bulk goods such as coal and iron ore, and the unloading is often carried out by a tipping machine system. After the open carriage is unhooked and unpacked, it is pulled into the tipping machine system. The tipping machine rotates the open carriage about 160 degrees for unloading, with a high degree of automation and high unloading efficiency.

[0003] When the car tipper rotates and unloads the car, the hook body will be tilted to the side of the unloading port due to gravity and cannot automatically return to its original position. The tilt of the hook body will cause the shunting machine to push the car and the subsequent collision hook to malfunction and even cause an accident.

[0004] In the prior art, in order to achieve safe coupling between the shunting locomotive hook and the open car hook, the open car hook needs to be straightened, including manual straightening and straightening by automated devices. Manual straightening is done by hand or by swinging a crowbar. Often, when the automated system of the car tipper is not interrupted, the operator waits for an opportunity to enter both ends of the car tipper and straighten it. The whole process carries the risk of personnel being drawn into the equipment. Automated device straightening mostly uses a straightening hook robot, which requires a specific track to be set up in the car tipper, has a complex structure and is costly. Summary of the invention

[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to further illustrate the present invention.

[0030] First, combine Figures 1 to 5 The invention discloses a coupler straightening device according to an embodiment of the present invention, which is used for straightening a coupler of an open wagon and has a wide range of application scenarios.

[0031] like Figures 1 to 5 As shown, the coupler straightening device 7 of the utility model embodiment is installed on the shunting machine 1 of the tipping machine system, specifically installed on the outside of the front hook at the head of the boom 11 of the shunting machine 1, and achieves the hook straightening function by quickly straightening the coupler 12 of the shunting machine 1 before the coupler 21 of the open car 2 collides and is connected, and is used to straighten the coupler 21 of the open car 2, and includes: a hook straightening module 3, a telescopic drive module 4, a distance measuring module 5, a control module and an identification module 6.

[0032] Specifically, Figures 1 to 5As shown, in this embodiment, the telescopic drive module 4 is arranged on the arm 11 of the shunting machine 1, and the driving end of the telescopic drive module 4 is connected to the positive hook module 3, driving the positive hook module 3 to approach the hook 21 of the open car 2; the positive hook module 3 is used to straighten the hook 21 of the open car 2; the distance measuring module 5 is arranged on the telescopic drive module 4, and the distance measuring module 5 detects the distance between the positive hook module 3 and the open car 2 in real time; the identification module 6 is arranged on the arm 11 of the shunting machine 1 and is opposite to the hook 21 of the open car 2, and the identification module 6 identifies the model of the hook 21 of the open car 2; the control module is connected with the telescopic drive module 4, the distance measuring module 5, the positive hook module 3 and the identification module 6. The distance measuring module 5 is a distance measuring sensor, which detects the distance between the positive hook module 3 and the open car 2 in real time to ensure high-precision positioning during the straightening process and reduce errors. The distance measuring module 5 can also use a radar. The radar can measure the distance and determine the type of the hook by detecting whether there is a chain and a handle above the hook 21 of the open car 2 or detecting the width of the hook. The control module is a controller. The identification module 6 is a camera that identifies the model of the coupler 21 of the open car 2, ensuring that the hook module 3 can be adaptively adjusted for different coupler models to improve the accuracy of operation. Real-time monitoring and dynamic adjustment ensure the safety of operation and reduce the risk of safety accidents caused by human operating errors; the automation system reduces the opportunity for workers to directly contact the coupler and reduces potential dangers at work. The coupler straightening device 7 has a compact structure and can be applied to all types of dumper systems. After being put into use, it can eliminate the need for manual hook straightening operations on the hook body.

[0033] Further, if Figures 1 to 5 As shown, in the present embodiment, the telescopic drive module 4 comprises: a fixed cylinder 41, which is fixed on the boom 11 of the shunting machine 1, providing a stable foundation; a pusher 42, which is fixed in the fixed cylinder 41 and connected to the control module; a telescopic cylinder 43, which is slidably arranged in the fixed cylinder 41, and the positive hook module 3 and the distance measuring module 5 are fixed on the telescopic cylinder 43. In the standby state, the telescopic cylinder 43 can be compactly retracted to reduce the occupied space and be more beautiful. At the same time, the fixed cylinder 41 limits and guides the telescopic direction of the telescopic cylinder 43; the output end of the pusher 42 is connected to the telescopic cylinder 43 to drive the telescopic cylinder 43 to extend and retract. The pusher 42 can adopt an electric push rod to provide a stable and controllable driving force to ensure that the telescopic cylinder 43 can be smoothly and accurately extended and retracted.

[0034] Further, if Figures 1 to 5As shown, in this embodiment, the telescopic drive module 4 further includes: a sliding bushing 44, which is arranged in the fixed cylinder 41 and is slidably connected with the telescopic cylinder 43. The sliding bushing 44 can effectively reduce the gap and swing of the telescopic cylinder 43 when sliding in the fixed cylinder 41, improve the stability and accuracy of the telescopic movement, and ensure that the positioning of the positive hook module 3 during the operation is more accurate; it can play a certain shock-absorbing role, absorb and buffer the impact and vibration in the telescopic movement, reduce noise, and improve the running stability and comfort of the system; it can reduce friction, reduce wear, and enhance load capacity.

[0035] Further, if Figures 1 to 5 As shown, in this embodiment, a buffer 45 is provided at one end of the telescopic cylinder 43 facing the gondola 2 to provide anti-collision protection under extreme working conditions.

[0036] Further, if Figures 1 to 5 As shown, in this embodiment, the hook module 3 includes: a push plate 31 and a driving member 32; the driving member 32 is arranged on the telescopic cylinder 43, and the driving member 32 is connected to the control module and the push plate 31. The driving member 32 drives the push plate 31 to straighten the coupler 21 of the open car 2, thereby realizing the automatic control of the movement of the push plate 31, reducing the error of human operation, and improving the operation efficiency and accuracy. The moving direction of the push plate 31 is perpendicular to the telescopic direction of the telescopic cylinder 43. Through the precise control of the driving member 32 and the uniform force of the push plate 31, an efficient, accurate and safe coupler straightening operation is realized. The driving member 32 can select an electric push rod according to specific needs, and the control is flexible and convenient.

[0037] According to the needs, the hook straightening device 7 can be arranged at the entrance and exit sides of the dumper to perform hook straightening operations on the rear hook and the front hook of the car to be dumped, respectively. When arranged at the exit, it is implemented in a front-to-back mirror arrangement. In the standby state, the telescopic cylinder 43 is in a retracted state; after the shunting machine 1 starts to push the car, the telescopic cylinder 43 is quickly pushed out. During the forward movement of the shunting machine 1, due to the different straightening distances of different hooks, the camera obtains the hook image, and the type of hook is identified through the machine vision system to provide data support for the straightening operation. At the same time, the distance measurement module 5 on the telescopic cylinder 43 detects the rear position of the open car 2 in real time to obtain the distance value. When the distance value is reduced to the trigger value, the pusher 42 of the telescopic cylinder 43 is controlled to gradually retract according to the distance change rate, but the position of the telescopic cylinder 43 and the open car 2 is kept relatively still. After the telescopic cylinder 43 remains "stationary", the push plate 31 is located in the most suitable position, and the hook module 3 is controlled. In combination with the coupler information data, the push plate 31 is started to push the corresponding coupler. At this time, the shunting locomotive 1 slows down and continues to move forward. Before the front hook of the shunting locomotive 1 touches the coupler 21 of the open car 2, the above-mentioned coupler identification, telescopic cylinder 43 retention, and push plate 31 straightening actions have been completed. The shunting locomotive 1 continues to move forward to complete the smooth connection of the straightened coupler.

[0038] Above, refer to Figures 1 to 5 The invention describes a coupler straightening device according to an embodiment of the utility model, which can realize automatic straightening of the open car coupler by the shunting locomotive during movement, ensure automatic coupling of the shunting locomotive hook and the open car coupler, eliminate the need for manual hook straightening operation, and has a simple and delicate overall structure.
