[0008] Preferably, the lubrication assembly includes a support rod disposed on one side of the pitch control room. Two fixed plates are fixedly installed on the upper end of the support rod, and a fixed pulley is rotatably mounted between the two fixed plates. A traction rope is wound around the axial side wall of the fixed pulley. A semi-circular clamp one is fixedly installed at one end of the traction rope. A semi-circular clamp two is threadedly connected to the semi-circular clamp one by screws. Both the semi-circular clamp one and the semi-circular clamp two have a cavity two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. With the cooperation of the pitch drum, crossbar, support arm, counterweight stud, and counterweight nut, the support arm rests on the stop pin and remains stationary. At this time, the support arm triggers the detection switch, sending a normal signal to the ship loader control system, and the ship loader can operate normally. When the ship loader boom encounters obstruction or imbalance during descent, the wire rope will sag and scrape against the crossbar, causing the support arm to rotate downwards via the rotating shaft. At this time, the detection switch detects that the support arm has disengaged from the stop pin and sends an abnormal signal to the ship loader control system, thereby stopping the ship loader operation and avoiding personal injury and mechanical damage.

[0014] 2. Since the ship loader operates outdoors, the wire rope inevitably accumulates a large amount of dust or debris after prolonged use, which can lead to fatigue and wire breakage. The accumulated dust increases the cross-section of the wire rope, potentially causing it to come into contact with the crossbar when taut, thus disconnecting the detection switch. The device, in conjunction with the traction rope, fixed pulley, semi-circular clamps (one and two), screws, wire rope, airbag, air intake channel, chamber two, lubricating oil, and drainage holes, lubricates and maintains the surface of the wire rope, preventing wire breakage due to prolonged tautness. The counterweight allows the device to slide downwards along the wire rope, while the cleaning brush removes dust and debris from the surface, preventing accidental contact with the crossbar and ensuring more accurate test results while reducing the workload of the operators.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-2 The system includes a pitch control room 1 and a chamber 11 located on the pitch control room 1. Two drum supports 12 are fixedly installed on the chamber 11. A pitch drum 13 is rotatably mounted between the two drum supports 12. A steel wire rope 6 is wound and connected on the pitch drum 13. A support assembly 3 is provided at the upper end of the pitch control room 1. The support assembly 3 includes two base plates 31 welded and fixed to the upper end of the pitch control room 1. Two vertical plates 32 are welded and fixed to the upper end of each of the two base plates 31. A top plate 33 is welded and fixed to the upper end of the two vertical plates 32. A stop pin 34 is welded and fixed to the side wall of one of the vertical plates 32. Two anchor bolt holes 35 are provided on the top plate 33. A bearing 36 is fixed to the upper end of the top plate 33 by anchor bolts 37. A detection assembly 2 is provided on the side wall of the bearing 36.

[0023] The detection assembly 2 includes a rotating shaft 25 rotatably mounted on the side wall of the bearing 36. A support arm 21 is fixedly mounted on one end of the rotating shaft 25. The support arm 21 has a mounting hole 22. A counterweight stud 23 is threaded to one end of the support arm 21. A counterweight nut 24 is threaded to the axial side wall of the counterweight stud 23. A crossbar stud 27 is threaded to the mounting hole 22. A crossbar 26 is welded and fixed between the two crossbar studs 27. A crossbar nut 28 is threaded to the axial side wall of the crossbar stud 27. A detection switch 29 is provided on the side wall of one of the support arms 21. A lubrication assembly 4 for maintaining the wire rope 6 is provided on one side of the pitch control room 1.

[0024] In this embodiment: First, the wire rope 6 is wound around the pitch drum 13. The wire rope 6 is located within a rectangular frame surrounded by two crossbars 26 and two support arms 21. Under the action of the tail counterweight stud 23 and counterweight nut 24, the support arm 21 rests on the stop pin 34 and remains stationary. At this time, the support arm 21 triggers the detection switch 29, which sends a normal signal to the ship loader control system, and the ship loader can operate normally. When the wire rope 6 is taut, it can pass smoothly through the rectangular frame. However, when the ship loader boom descends and there is obstruction or imbalance, the wire rope 6 will sag and scrape against the crossbar 26, causing the support arm 21 to rotate downward through the rotating shaft 25. At this time, the detection switch 29 detects that the support arm 21 has disengaged from the stop pin 34 and sends an abnormal signal to the ship loader control system, thereby stopping the ship loader operation and avoiding personal injury and mechanical damage.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 3-5 The lubrication assembly 4 includes a support rod 41 located on one side of the pitch control room 1. Two fixed plates 42 are fixedly installed on the upper end of the support rod 41. A fixed pulley 43 is rotatably installed between the two fixed plates 42. A traction rope 44 is wound around the axial side wall of the fixed pulley 43. A semi-circular clamp 45 is fixedly installed at one end of the traction rope 44. A semi-circular clamp 47 is threadedly connected to the semi-circular clamp 45 by screws 46. Both the semi-circular clamp 45 and the semi-circular clamp 47 have a second chamber 48. The second chamber 48 has several drainage holes 49 and ventilation holes 402. An air intake channel 401 is provided inside the traction rope 44. An airbag 403 is fixedly installed at one end of the traction rope 44. The airbag 403 and the air intake channel 401 are connected. A cleaning assembly 5 is provided on the semi-circular clamp 45.

[0026] The cleaning assembly 5 includes a cleaning brush 51 bonded to a semi-circular clamp 45 and a semi-circular clamp 47. A counterweight 52 is fixedly installed at the lower end of both the semi-circular clamp 45 and the semi-circular clamp 47. Two fixed rods 53 are fixedly installed at the upper end of the pitching machine room 1. A connecting rod 54 is fixedly installed between the two fixed rods 53. One end of the traction rope 44 is provided with a winding rope 55.

[0027] The dimensions formed by the semi-circular clamp 45 and the semi-circular clamp 47 are consistent with the diameter of the wire rope 6, allowing them to slide back and forth on the wire rope 6 to lubricate its surface.

[0028] The traction rope 44 is at the upper end of the wire rope 6 to prevent the traction rope 44 and the wire rope 6 from getting tangled together.

[0029] In this embodiment: Since the ship loader operates outdoors, after a long period of operation, the wire rope 6 inevitably accumulates a large amount of dust or debris, which may lead to fatigue breakage of the wire rope 6. The accumulated dust increases the cross-section of the wire rope 6, which may cause dust or debris to come into contact with the crossbar 26 when the wire rope 6 is taut, causing the detection switch 29 to disconnect. At this time, the traction rope 44 is passed through the fixed pulley 43, and the semi-circular clamp 1 45 and semi-circular clamp 2 47 are fastened to the wire rope 6 with screws 46. Then, the airbag 403 is pressed to allow gas to enter the second chamber from the air intake channel 401. 48, thereby draining the lubricating oil in chamber 2 48 through several drainage holes 49, thus lubricating and maintaining the surface of the wire rope 6. The lubricating oil in the semi-arc clamp 2 47 can be sprayed onto the wire rope 6 through the vent hole 402, preventing the wire rope 6 from breaking due to prolonged tension. At this time, under the action of the counterweight 52, the device can slide down the wire rope 6. At this time, the cleaning brush 51 cleans the dust or debris on the surface of the wire rope 6, avoiding accidental contact with the crossbar 26, which would cause errors in the test results, making the test results more accurate and reducing the workload of the staff.
