Description

A monitoring and protection device for preventing job jumping Technical Field

[0001] This application relates to the field of lifting machinery technology, and in particular to an anti-slip monitoring and protection device. Background Technology

[0002] In large port cranes, the hoisting device is a major component, and its lifting function is mainly achieved by the motor driving the wire rope on the drum to wind.

[0003] The wire rope is wound regularly along the grooves on the drum. However, with the wear of the grooves on the drum and the frequent high-speed operation of the hoisting device, the wire rope is prone to jumping out of the grooves during the lifting process, which poses a great threat to safe operation and increases repair costs. Summary of the Invention

[0004] In order to reduce the probability of wire rope jumping and reduce safety hazards, this application provides an anti-jump monitoring and protection device.

[0005] The anti-spinning monitoring and protection device provided in this application adopts the following technical solution:

[0006] A monitoring and protection device for preventing wire rope jumping includes a fixed bracket and a drum rotatably mounted on the fixed bracket for winding a wire rope. The drum has rope grooves evenly arranged along its axial direction. The device also includes a limiting member disposed on the fixed bracket and located at the bottom of the drum, and a warning component disposed at one end of the drum. A limiting gap is formed between the limiting member and the wire rope arranged in the rope groove to limit the jumping of the wire rope.

[0007] By adopting the above technical solution, the limiting gap formed between the limiting component and the wire rope can restrict the wire rope's jump, thereby avoiding wire rope derailment caused by groove wear or frequent operation, improving equipment operation safety and reducing maintenance costs. The warning component can issue an alarm when the wire rope deviates from its normal position, further ensuring operational safety.

[0008] Optionally, the limiting component includes a limiting frame and a limiting roller rotatably mounted on the limiting frame.

[0009] By adopting the above technical solution, the limiting component consists of a limiting frame and a limiting roller rotatably mounted on the limiting frame, enabling the limiting roller to maintain rolling contact with the wire rope. This method effectively reduces the frictional resistance of the limiting component on the movement of the wire rope, while the supporting effect of the limiting frame ensures that the limiting roller stably restricts the position of the wire rope, preventing it from jumping out of its groove.

[0010] Optionally, the limiting roller and the drum are arranged in parallel, and the length of the limiting roller is adapted to the rope groove.

[0011] By adopting the above technical solution, the parallel arrangement of the limiting roller and the drum ensures a stable relative position between them, thereby forming a uniform limiting gap and effectively preventing the wire rope from jumping out of the groove during drum rotation. The length of the limiting roller is adapted to the rope groove, allowing the limiting roller to fully cover the rope groove area, further improving the limiting effect on the wire rope and enhancing the safety and reliability of equipment operation.

[0012] Optionally, the warning component includes a warning bracket and a warning sensor rotatably mounted on the warning bracket. The warning sensor corresponds to an empty rope groove on the drum, and the distance from the warning sensor to the empty rope groove is less than the radial width of the wire rope.

[0013] By adopting the above technical solution, the structural composition of the early warning component is specifically disclosed, which enables the early warning sensor to be triggered in time when the wire rope jumps out of the groove and deviates from the normal position, thereby alerting the operators in advance to take measures to avoid safety hazards and equipment damage caused by the wire rope jumping out of the groove.

[0014] Optionally, the limiting frame includes two sets of first support plates fixed to the fixed bracket and a second support plate disposed inside the first support plates. The first support plates and the second support plates are bolted together, and the limiting roller is disposed on the second support plate.

[0015] By adopting the above technical solution, the limiting frame consists of two sets of first support plates and second support plates. The first support plate is fixed to the fixed bracket, and the second support plate is located inside the first support plate and fixed with bolts. The limiting roller is located on the second support plate. This structural design makes the assembly and disassembly of the limiting frame more convenient, and also facilitates the adjustment and maintenance of the position of the limiting roller.

[0016] Optionally, the limiting frame includes two sets of first support plates fixed to the fixed bracket and a second support plate disposed inside the first support plate, wherein the first support plate and the second support plate slide in cooperation.

[0017] By adopting the above technical solution, the limiting frame consists of two sets of first support plates fixed to the fixed bracket and a second support plate disposed inside the first support plates, with the first and second support plates slidingly engaged. This structural design allows the position of the limiting frame to be flexibly adjusted, thereby better adapting to different specifications of wire ropes or rope grooves and improving the versatility and ease of adjustment of the device.

[0018] Optionally, the first support plate is provided with a lifting slide groove, the extension direction of the lifting slide groove is parallel to the radial direction of the drum, the second support plate is provided with a lifting slide rail that slides and cooperates with the lifting slide groove, and the first support plate is provided with a locking member in the lifting slide groove for locking the second support plate.

[0019] By adopting the above technical solution, the lifting groove on the first support plate cooperates with the lifting rail on the second support plate, so that the second support plate can slide and adjust along the radial direction of the drum. This allows the position of the limiting roller to be flexibly adjusted according to actual needs to adapt to wire ropes or rope grooves of different diameters.

[0020] Optionally, the second support plate includes a sliding seat that slides in conjunction with the first support plate and a lifting plate that is rotatably mounted on the sliding seat.

[0021] By adopting the above technical solution, the sliding seat and the first support plate slide together, allowing the second support plate to be adjusted in position along the first support plate, thereby adapting to drums or wire ropes of different specifications and improving the applicability of the device. Simultaneously, the lifting plate is rotatably mounted on the sliding seat, allowing the operator to rotate the lifting plate according to the usage conditions.

[0022] Optionally, the sliding seat is provided with a rotating groove, the lifting plate is provided with a rotating head that is inserted into the rotating groove, the rotating groove is provided with a limiting arc groove that limits the rotation angle of the rotating head, the sliding seat is provided with a locking hole and a locking pin at both ends of the limiting arc groove, and the rotating head is provided with a locking through hole for the locking pin to be inserted.

[0023] By adopting the above technical solution, the rotating head of the lifting plate is inserted into the rotating groove, and the limiting arc groove restricts the rotation angle of the rotating head, thereby realizing the angle adjustment of the lifting plate and ensuring its stability. The locking hole and locking pin cooperate to fix the rotating head in a specific position, preventing it from loosening or shifting during operation.

[0024] Optionally, the first support plate is provided with a scraping assembly for scraping the side wall of the limiting member on the side away from the limiting arc groove. The scraping assembly includes a scraping frame and a scraping blade disposed on the scraping frame.

[0025] By adopting the above technical solution, the scraping assembly can effectively remove impurities or residues adhering to the side wall of the limiting component. The combined use of the scraping frame and the scraping blade ensures that the side wall of the limiting component remains clean throughout the operation of the device.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting a limiting component at the bottom of the drum and forming a limiting gap with the wire rope, the jumping of the wire rope is effectively limited, significantly reducing the risk of the wire rope jumping off the groove, thereby improving the safety of the hoisting device;

[0028] 2. The early warning sensor in the early warning component can correspond to the empty rope groove of the drum, monitor the running status of the wire rope in real time, detect abnormalities in time and issue early warnings, and avoid safety hazards caused by rope slippage.

[0029] 3. The sliding cooperation between the first and second support plates, as well as the rotational cooperation between the sliding seat and the lifting plate, allows the second support plate to be positioned along the first support plate, thereby adapting to drums or wire ropes of different specifications. At the same time, it fixes the rotating head in a horizontal position, making it convenient to clean and replace the wire rope. Attached Figure Description

[0038] The present application will be further described in detail below with reference to Figures 1-7.

[0039] This application discloses an anti-spinning monitoring and protection device.

[0040] Example 1:

[0041] Referring to Figure 1, an anti-slip monitoring and protection device includes a fixed bracket 1, a drum 2 rotatably mounted on the fixed bracket 1, a limiting member 3 disposed on the fixed bracket 1 and located at the bottom of the drum 2, and an early warning component 4. The drum 2 has rope grooves evenly arranged along its axial direction for arranging steel wire ropes, wherein the outermost rope groove is an empty rope groove 21.

[0042] Referring to Figures 2 and 3, the limiting member 3 includes a limiting frame 31 and a limiting roller 32 rotatably mounted on the limiting frame 31. A limiting gap 321 is formed between the limiting roller 32 and the wire rope arranged in the rope groove. The limiting gap 321 is smaller than the width of the wire rope to limit the jump of the wire rope. The length of the limiting roller 32 is consistent with the arrangement length of the rope groove, and the limiting roller 32 and the drum 2 are arranged in parallel to ensure that the wire rope on the drum 2 is limited by the limiting roller 32.

[0043] The limiting frame 31 includes two sets of first support plates 311 and two sets of second support plates 312. The first support plates 311 are L-shaped and are fixed to the bottom of the fixing bracket 1 by bolts. The second support plates 312 are disposed on the inner side of the two sets of first support plates 311 and are fixed to the first support plates 311 by bolts.

[0044] The warning assembly 4 includes a warning bracket 41 and a warning sensor 42 rotatably mounted on the warning bracket 41. The warning bracket 41 is fixed to the fixed bracket 1 by bolts. The warning sensor 42 and the empty rope groove 21 are correspondingly arranged, and a roller is rotatably mounted on the end of the warning sensor 42 facing the drum 2 for the jumping wire rope to abut against. The distance from the roller to the empty rope groove 21 is less than the radial width of the wire rope. The warning sensor 42 is a pressure sensor. When the wire rope jumps to the empty rope groove 21, the wire rope hits the roller, causing the warning sensor 42 to rotate, thus generating a signal to stop the lifting operation.

[0045] Example 2: Except for the connection structure of the first support plate 311 and the second support plate 312, the structure of this example is the same as that of Example 1.

[0046] Referring to Figures 4 and 5, the limiting frame 31 includes a first support plate 311 and a second support plate 312. The first support plate 311 is an L-shaped plate and is fixed to the bottom of the fixed bracket 1 by bolts. The second support plate 312 is slidably mounted on the first support plate 311 so that the size of the limiting gap 321 can be adjusted by adjusting the second support plate 312.

[0047] The first support plate 311 has a lifting groove 3111 along the height direction, and a locking member 3112 for locking the second support plate 312 is provided on the lifting groove 3111. In this embodiment, the locking member 3112 is a locking bolt. The first support plate 311 has a strip hole 3113 along the height direction on the bottom wall of the lifting groove 3111, and the locking bolt passes through the strip hole 3113 and is threaded to the second support plate 312.

[0048] The second support plate 312 includes a sliding seat 3121 that slides and engages with the lifting slide groove 3111, and a lifting plate 3122 rotatably mounted on the sliding seat 3121. The sliding seat 3121 has a lifting slide rail 31211 that engages with the lifting slide groove 3111, and a locking screw hole 31212 that engages with a locking bolt. The sliding seat 3121 has a rotating groove 31213 on its end face away from the lifting slide groove 3111, and the bottom of the lifting plate 3122 is integrally provided with a rotating head 31221 that is inserted into the rotating groove 31213.

[0049] Referring to Figure 6, the sliding seat 3121 has a limiting arc groove 31214 on the inner wall of the rotating groove 31213. The arc of the limiting arc groove 31214 is 90°, so that the lifting plate 3122 has two rotation states on the sliding seat 3121. When the lifting plate 3122 is at one end of the limiting arc groove 31214, the lifting plate 3122 is in a vertical state, which serves to limit the wire rope. When the lifting plate 3122 is at the other end of the limiting arc groove 31214, the lifting plate 3122 is in a horizontal state. The horizontal state of the lifting plate 3122 makes it easier for workers to clean and replace the wire rope and the drum 2.

[0050] The rotating head 31221 has an arc-shaped block that is positioned within the limiting arc groove 31214, and a locking through hole 31222 is provided on the arc block. The sliding seat 3121 has locking holes 31215 at both ends of the limiting arc groove 31214, and a locking pin 31216 is provided in the locking hole 31215. The locking pin 31216 passes through the locking hole 31215 and the locking through hole 31222 in sequence to lock the lifting plate 3122.

[0051] Referring to Figure 7, the operating conditions of the lifting device of drum 2 are relatively harsh, and dirt and debris usually adhere to the limiting roller 32. In order to reduce the impact of these adhered debris on the limiting roller 32, this application also includes a scraper assembly 33. The scraper assembly 33 includes a scraper frame 331 fixed to the first support plate 311 and a scraper blade 332 installed on the scraper frame 331. The scraper frame 331 is located on the side of the first support plate 311 away from the limiting arc groove 31214. The scraper frame 331 is a U-shaped frame with its opening facing the limiting roller 32. The scraper blade 332 is fixed in the U-shaped groove of the scraper frame 331, and the end of the scraper blade 332 is close to the limiting roller 32.

[0052] The implementation principle of the anti-slip monitoring and protection device in this application embodiment is as follows: The limiting member 3 is fixed below the drum 2. By adjusting the second support plate 312, the distance between the limiting roller 32 and the wire rope is adapted to the limiting gap 321. When the wire rope needs to be replaced or cleaned, the second support plate 312 is rotated, causing the limiting roller 32 to switch from a vertical to a horizontal state. The limiting roller 32 is then manually rotated, and the scraper blade 332 scrapes off any adhering debris on the limiting roller 32.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
