Description

Technical Field

[0001] The utility model relates to the technical field of movable ballast robots, in particular to a rope retracting device for a movable ballast trolley. Background Art

[0002] When the salt field automatic movable ballast robot is working in movable ballast operation, there will be a problem of entanglement of plastic thatch rope. Therefore, the movable ballast rake needs to be able to automatically lift when encountering the rope, that is, a sensor is required to sense the plastic thatch rope.

[0003] The Chinese patent application number is 202421447268.5. A rope retracting sensor for a movable ballast trolley that can be used underwater for a long time includes a movable ballast rake body, a basic mounting frame is mounted on the surface of the movable ballast rake body through fixing bolts, and a non-contact sensor is mounted on the left side wall of the basic mounting frame;

[0004] Regarding the above patent, after testing, missed detection may occur, because the bottom end of the trigger rod of the currently designed rope retraction sensor is a certain distance away from the bottom salt layer when working, and is larger than the diameter of the plastic thatch rope. Therefore, when the plastic thatch rope is attached to the bottom salt layer, the currently designed rope retraction sensor cannot sense it, resulting in missed detection. In the process of detecting the plastic thatch rope, the plastic thatch rope needs to be hung on the trigger rod. With the current structure, the plastic thatch rope may fall off before the trigger rod triggers the sensor, resulting in missed detection.

[0005] For this reason, a rope-retracting device for a movable ballast trolley is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problems raised in the above-mentioned background technology, and the utility model provides a rope retracting device for a movable ballast trolley.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] A rope retracting device for a movable ballast trolley comprises a vehicle body, a connecting frame is provided at the rear of the vehicle body, and the vehicle body is connected to a movable ballast rake body through the connecting frame, a mounting assembly is provided on the surface of the movable ballast rake body, a trigger rod is rotatably mounted on the surface of the mounting assembly, an adjustable extension assembly is provided on the surface of the trigger rod, a torsion spring is provided at the bottom end of the adjustable extension assembly, and a hook is fixedly mounted on the bottom end of the adjustable extension assembly through the torsion spring.

[0009] Furthermore, the movable ballast rake body comprises a frame body, the frame body is installed on the rear side of the vehicle body via a connecting frame, a frame is fixedly installed on the bottom surface of the frame body, and the rake body is fixedly installed on the bottom surface of the frame.

[0010] Furthermore, the mounting assembly includes a vertical rod, and the vertical rod is fixedly installed on the inner top of the frame and the top surface of the frame, a plurality of through holes are opened on the surface of the vertical rod, and a mounting plate is fixedly installed on the surface of the vertical rod by a first fixing bolt, a rope retraction sensor is arranged on the surface of the mounting plate, a non-contact sensor is arranged on one side wall of the mounting plate, and a trigger rod is rotatably installed on the other side wall of the mounting plate.

[0011] Furthermore, the adjustable extension assembly includes an extension rod, the bottom end of the trigger rod is movably sleeved with the extension rod, the surface of the extension rod is provided with a through groove, a second fixing bolt is inserted into the inside of the trigger rod, and the second fixing bolt is located inside the through groove, and the bottom end of the extension rod is fixed with a hook by a torsion spring.

[0012] Furthermore, a cross frame is fixedly installed at the rear of the vehicle body, and two groups of rope-pulling pieces are fixedly installed on the bottom surface of the cross frame. The two groups of rope-pulling pieces are arranged obliquely and are respectively located on both sides of the trigger rod.

[0013] Furthermore, the frontmost portion of one end of the hook is tilted upward.

[0014] The beneficial effects of the utility model are as follows:

[0015] When the vehicle body is performing active ballast work, after the vehicle body passes through the plastic thatch rope attached to the underwater salt layer, the hook attached to the underwater salt layer and moving with the vehicle body will hook the plastic thatch rope. As the vehicle body continues to move forward, the plastic thatch rope will drive the trigger rod to rotate backward. When the trigger rod rotates a certain angle, the retraction rope sensor senses the plastic thatch rope and orders the trolley to stop moving. At the same time, the active ballast rake body is lifted upward through the driving equipment of the vehicle body. The retraction rope sensor and the hook installed on the active ballast rake body will move upward with the plastic thatch rope. When the active ballast rake body is lifted to a certain height, the rope pulling piece will block the plastic thatch rope on the hook, and the active ballast rake body continues to move upward. Because the rope pulling piece blocks the plastic thatch rope, the torsion spring connected to the hook will undergo torsional elastic deformation, and the hook will rotate upward. After the rotation angle of the hook reaches a certain degree, the plastic thatch rope falls off and falls back into the salt field. At the same time, the torsion spring returns to its original state, causing the hook to return to its original position. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 7 As shown, a rope retracting device for a movable ballast trolley comprises a vehicle body 1, a connecting frame 2 is provided at the rear of the vehicle body 1, and the vehicle body 1 is connected to a movable ballast rake body 3 through the connecting frame 2, a mounting assembly 4 is provided on the surface of the movable ballast rake body 3, and a trigger rod 7 is rotatably mounted on the surface of the mounting assembly 4, and an adjustable extension assembly 8 is provided on the surface of the trigger rod 7, and a torsion spring 9 is provided at the bottom end of the adjustable extension assembly 8, and a hook 10 is fixedly mounted on the bottom end of the adjustable extension assembly 8 through the torsion spring 9. More specifically, when the vehicle body 1 is performing active ballast work, after the vehicle body 1 passes through the plastic thatch rope attached to the underwater salt layer, the hook 10 attached to the underwater salt layer and moving with the vehicle body 1 will hook the plastic thatch rope, and the vehicle body 1 continues to move forward, and the plastic thatch rope will drive the trigger rod 7 to rotate backward. When the trigger rod 7 rotates a certain angle, the rope retraction sensor 5 senses the plastic thatch rope, and orders the trolley to stop moving forward. At the same time, the active ballast rake body 3 is lifted upward through the driving device of the vehicle body 1, and the rope retraction sensor installed on the active ballast rake body 3 The sensor 5 and the hook 10 will move upward with the plastic thatch rope. When the movable ballast rake body 3 is lifted to a certain height, the rope-pulling piece 12 will block the plastic thatch rope on the hook 10, and the movable ballast rake body 3 continues to move upward. Because the rope-pulling piece 12 blocks the plastic thatch rope, the torsion spring 9 connected to the hook 10 will undergo torsional elastic deformation, and the hook 10 will rotate upward. After the rotation angle of the hook 10 reaches a certain degree, the plastic thatch rope will fall off and fall back into the salt field. At the same time, the torsion spring 9 returns to its original state, causing the hook 10 to return to its original position.

[0029] The movable ballast rake body 3 includes a frame 301, the frame 301 is installed on the rear side of the vehicle body 1 through the connecting frame 2, the frame 302 is fixedly installed on the bottom surface of the frame 301, and the rake body 303 is fixedly installed on the bottom surface of the frame 302. More specifically, the frame 301 and the connecting frame 2 are connected to achieve fixation with the rear of the vehicle body 1.

[0030] The mounting assembly 4 includes a vertical rod 401, the vertical rod 401 is fixedly mounted on the inner top of the frame 301 and the top surface of the frame 302, a plurality of through holes are provided on the surface of the vertical rod 401, and a mounting plate 403 is fixedly mounted on the surface of the vertical rod 401 through a first fixing bolt 402, a rope retraction sensor 5 is arranged on the surface of the mounting plate 403, a non-contact sensor 6 is arranged on one side wall of the mounting plate 403, and a trigger rod 7 is rotatably mounted on the other side wall of the mounting plate 403. More specifically, the position of the mounting plate 403 on the side wall of the vertical rod 401 can be adjusted by the first fixing bolt 402, and the mounting plate 403 and the vertical rod 401 are installed and fixed by the first fixing bolt 402.

[0031] The adjustable extension assembly 8 includes an extension rod 801, the bottom end of the trigger rod 7 is movably sleeved with the extension rod 801, a through slot 802 is provided on the surface of the extension rod 801, a second fixing bolt 803 is inserted into the inside of the trigger rod 7, and the second fixing bolt 803 is located inside the through slot 802, and a hook 10 is fixedly installed at the bottom end of the extension rod 801 through a torsion spring 9. More specifically, the second fixing bolt 803 is used to release the fixation between the extension rod 801 and the trigger rod 7, and the positions of the torsion spring 9 and the hook 10 are adjusted by movably inserting the extension rod 801 and the bottom end of the trigger rod 7, so that the hook 10 can be extended to the bottom salt layer.

[0032] A cross frame 11 is fixedly installed at the rear of the vehicle body 1, and two sets of rope-pulling pieces 12 are fixedly installed on the bottom surface of the cross frame 11. The two sets of rope-pulling pieces 12 are arranged obliquely and are respectively located on both sides of the trigger rod 7. More specifically, the plastic rope on the hook 10 moving upward can be made to fall off by the two sets of rope-pulling pieces 12 being arranged obliquely.

[0034] In summary: when the vehicle body 1 is working with live ballast, after the vehicle body 1 passes through the plastic thatch rope attached to the bottom salt layer, the hook 10 attached to the bottom salt layer and moving with the vehicle body 1 will hook the plastic thatch rope, and the vehicle body 1 continues to move forward, and the plastic thatch rope will drive the trigger rod 7 to rotate backward. When the trigger rod 7 rotates a certain angle, the rope retraction sensor 5 senses the plastic thatch rope, orders the trolley to stop moving forward, and at the same time, the live ballast rake body 3 is lifted upward through the driving device of the vehicle body 1, and the rope retraction sensor installed on the live ballast rake body 3 The device 5 and the hook 10 will move upward with the plastic thatch rope. When the movable ballast rake body 3 is lifted to a certain height, the rope-pulling piece 12 will block the plastic thatch rope on the hook 10, and the movable ballast rake body 3 continues to move upward. Because the rope-pulling piece 12 blocks the plastic thatch rope, the torsion spring 9 connected to the hook 10 will undergo torsional elastic deformation, and the hook 10 will rotate upward. After the rotation angle of the hook 10 reaches a certain degree, the plastic thatch rope will fall off and fall back into the salt field. At the same time, the torsion spring 9 returns to its original state, causing the hook 10 to return to its original position.
