Description

Technical Field

[0001] This utility model relates to the field of port equipment technology, and in particular to a device for correcting the deviation of the rear traction rope of a quay crane trolley. Background Technology

[0002] A quay crane is a specialized crane used for loading and unloading container ships at the front of a container terminal. They are categorized into fully rope trolley quay cranes, semi-rope trolley quay cranes, and self-propelled trolley quay cranes. Fully rope and semi-rope trolley quay cranes move their trolleys by being pulled by ropes, resulting in a relatively simple structure. Self-propelled trolley quay cranes, on the other hand, have trolleys with independent drive systems, offering high speed and positioning accuracy.

[0003] The rear traction rope of the quay crane trolley is a key component of the trolley's running mechanism. During operation, the traction rope repeatedly comes into contact with and rubs against the drive drum and guide pulley, and the surface steel wires will gradually wear down, resulting in a decrease in the overall breaking tensile strength. If the wear exceeds the standard, the rope's load-bearing capacity will be greatly reduced, and it may suddenly break under stress, reducing safety. Therefore, the rear traction rope usually needs to be replaced after a period of use.

[0004] When replacing the trolley's rear traction rope, the traction rope on the trolley drum may interfere with or directly contact the lifting brake connecting rod as it passes through the winch in the machine room. This can easily damage the lifting brake push rod and the traction rope, thus creating a safety hazard in use. Utility Model Content

[0005] To address the technical problem in the prior art where, during replacement of the trolley's rear traction rope, the traction rope interferes with and directly contacts the lifting brake connecting rod, easily causing damage to the lifting brake push rod and the traction rope, this utility model provides a trolley rear traction rope correction device.

[0006] The technical solution of this utility model is as follows: This utility model provides a device for correcting the deviation of the traction rope of a quay crane trolley. The device includes a fixed base, which is used to fasten onto the lifting brake connecting rod. The fixed base has an inverted U-shaped structure. A limit bolt and a tightening bolt are threaded onto the fixed base, both arranged horizontally. A support seat is installed on the top of the fixed base, and a roller is rotatably mounted on the support seat. By fastening the fixed base onto the lifting brake connecting rod, the limit bolt and tightening bolt stabilize the device's position, preventing loosening and displacement. The rotating roller contacts the traction rope, guiding it along the correct path and avoiding direct contact and interference between the traction rope and the lifting brake connecting rod. This protects the lifting brake push rod and the traction rope, eliminating safety hazards. The entire device is easy to assemble, disassemble, and use, and has strong applicability.

[0007] Preferably, the fixed base includes two opposing first vertical plates, the tops of which are fixedly connected together by a first horizontal plate. A limiting bolt and a tightening bolt are mounted on one of the first vertical plates. This forms a stable frame for the fixed base, enhancing overall rigidity and better withstanding the force exerted by the traction rope. Simultaneously, mounting the limiting bolt and tightening bolt on the same first vertical plate facilitates centralized operation and adjustment, improving the ease of installation and adjustment of the device.

[0008] Preferably, the limiting bolt is located below the tightening bolt. During use, the limiting bolt is positioned below the lifting brake connecting rod. The limiting bolt provides initial vertical restraint to the fixed base, while the tightening bolt further tightens and fixes it from the side to limit lateral swaying. This makes the connection between the fixed base and the connecting rod more secure and reliable, preventing the device from swaying up and down or back and forth under the action of the traction rope, and ensuring the stability of the correction effect.

[0009] Preferably, the length of the limiting bolt is greater than the distance between the two first vertical plates. This ensures that the limiting bolt can pass through the space between the two first vertical plates, providing effective support and limiting for the first vertical plate on the other side, further enhancing the stability of the connection between the fixed base and the lifting brake connecting rod.

[0010] Preferably, each of the two first vertical plates has a through hole, and the limiting bolt is placed between the two through holes. The through holes provide a stable installation and passage for the limiting bolt, and the two first vertical plates support both ends of the limiting bolt, thereby improving the installation stability and firmness of the limiting bolt.

[0011] Preferably, the first vertical plate has a through hole, and a nut is fixedly installed at the through hole. The nut can be threadedly connected to the corresponding limit bolt or tightening bolt.

[0012] Preferably, the support base has a U-shaped structure and includes a second horizontal plate. The length direction of the second horizontal plate of the support base is perpendicular to the length direction of the first horizontal plate of the fixed base. The U-shaped support base provides a stable installation space for the roller, ensuring flexible roller rotation. The perpendicularity of the second horizontal plate of the support base to the first horizontal plate of the fixed base allows the roller's axial direction to be aligned with the running direction of the traction rope, better guiding the traction rope and improving the correction effect.

[0013] Preferably, the outer diameter of the roller at its middle is smaller than the outer diameters at its two ends. This creates an inwardly concave arc shape on the roller surface, which better guides and limits the traction rope, preventing it from slipping off the roller during operation and ensuring that the traction rope always moves along the correct path, further reducing interference with other components.

[0014] Preferably, an adjusting seat is fixedly provided on the top of the fixed base, and the support seat is installed on the adjusting seat. The adjusting seat provides an adjustable mounting base for the support seat, which facilitates the adjustment of the position of the support seat and the roller according to the actual position of the traction rope and the running path, so that the roller can cooperate more accurately with the traction rope, improving the applicability and correction accuracy of the device.

[0015] Preferably, the top of the adjusting seat has a groove extending along the axial direction of the roller. A screw is rotatably mounted inside the groove, and a slider is fixedly mounted at the bottom of the support seat. The slider is threadedly connected to the screw and slides within the groove. A handle is fixedly connected to one end of the screw. By rotating the handle, the screw is rotated, causing the slider to slide within the groove. This allows for precise adjustment of the support seat and roller along the groove direction. The operation is simple and flexible, quickly adapting to changes in the position of the traction rope under different working conditions. This ensures that interference between the traction rope and the lifting brake connecting rod is always effectively avoided, guaranteeing safe operation of the equipment.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are: 1. By fastening the fixed base to the lifting brake connecting rod, the position of the device can be stabilized using limit bolts and tightening bolts. It is suitable for connecting and fixing with the lifting brake connecting rod, preventing the device from loosening or shifting. The rotating roller can contact the traction rope, guiding the traction rope to run along the correct path, avoiding direct contact between the traction rope and the lifting brake connecting rod to prevent interference, thereby protecting the lifting brake push rod and the traction rope, eliminating safety hazards. The entire device is easy to assemble, disassemble, and use, and has strong applicability.

[0017] 2. The adjusting seat provides an adjustable mounting base for the support seat, which makes it easy to adjust the position of the support seat and roller according to the actual position of the traction rope and the running path, so that the roller can cooperate more accurately with the traction rope, improving the applicability and correction accuracy of the device.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Example 1 In a typical embodiment of this utility model, such as Figure 1 As shown, a traction rope correction device for a quay crane trolley is proposed, comprising: a fixed base 1, a limiting bolt 2, a tightening bolt 3, a support seat 5, and a roller 6. The limiting bolt 2 and the tightening bolt 3 are both threadedly connected to the fixed base 1 to fix the position of the fixed base 1. The support seat 5 is fixedly installed on the fixed base 1 by welding and is used to support the roller 6. The roller 6 is rotatably mounted on the support seat 5 via a rotating shaft 7.

[0022] Specifically, the fixed base 1 is an inverted U-shaped structure. The fixed base 1 includes a first horizontal plate 14 and a first vertical plate 13. There are two first vertical plates 13, and the two first vertical plates 13 are arranged opposite to each other. The tops of the two first vertical plates 13 are fixedly connected together through the first horizontal plate 14. The inverted U-shaped structure makes it easy to fasten the fixed base 1 to the connecting rod of the lifting brake, which facilitates the connection between the fixed base 1 and the connecting rod of the lifting brake.

[0023] In this embodiment, the length of the first vertical plate 13 of the fixed base 1 is greater than the thickness of the lifting brake connecting rod. A limit bolt 2 and a tightening bolt 3 are threadedly connected to one of the first vertical plates 13 of the fixed base 1. The limit bolt 2 and the tightening bolt 3 are both arranged horizontally, that is, the limit bolt 2 and the tightening bolt 3 are both parallel to the first horizontal plate 14, and the limit bolt 2 is located below the tightening bolt 3. The limit bolt 2 is used to be screwed between the two first vertical plates 13 and placed at the bottom of the lifting brake connecting rod to play a vertical limiting role. The tightening bolt 3 is used to be screwed to the side of the lifting brake connecting rod to tighten the side of the lifting brake connecting rod, thereby achieving a horizontal limiting of the fixed base 1.

[0024] Specifically, two through holes 15 are opened vertically at intervals along the first vertical plate 13 of the fixed base 1. A nut 4 is welded and fixed at each through hole 15. The nut 4 is used for threaded connection with the limit bolt 2 and the tightening bolt 3.

[0025] It is understandable that the nut 4 can be fixedly installed on the outside of the through hole 15, or it can be directly fixedly installed inside the through hole 15, or the through hole 15 can be set as a threaded hole structure to eliminate the need for the nut 4. The specific choice can be made according to the actual design requirements, and no further restrictions are imposed here.

[0026] In this embodiment, in order to provide a better vertical limiting effect, the length of the limiting bolt 2 is greater than the distance between the two first vertical plates 13, and through holes 15 are provided at the relative positions of the two first vertical plates 13, so that the limiting bolt 2 is placed between the two through holes 15, thereby using the two first vertical plates 13 to support the two ends of the limiting bolt 2, thereby improving the installation stability and firmness of the limiting bolt 2.

[0027] like Figure 1 As shown, the support base 5 has a U-shaped structure. The support base 5 includes a second horizontal plate 17 and a second vertical plate 16. There are two second vertical plates 16, which are arranged opposite to each other. The bottoms of the two second vertical plates 16 are welded and fixed together by the second horizontal plate 17. The length direction of the second horizontal plate 17 of the support base 5 is perpendicular to the length direction of the first horizontal plate 14 of the fixed base 1, that is, they are arranged in a cross shape. The roller 6 is rotatably arranged between the two second vertical plates 16 of the support base 5 through the rotating shaft 7.

[0028] In this embodiment, the rotating shaft 7 and the second vertical plate 16 of the support base 5 are fixedly connected together by welding, nut fixing or other means. The roller 6 is rotatably mounted on the rotating shaft 7. In order to further reduce the wear of the roller 6, a bearing can be set between the roller 6 and the rotating shaft 7.

[0029] Roller 6 is a grooved roller structure with a middle outer diameter smaller than the outer diameters at both ends. This restricts the position of the traction rope, guides the traction rope, and prevents the traction rope from directly contacting the connecting rod of the lifting brake, thus preventing damage to the lifting brake connecting rod and the traction rope.

[0030] The specific working principle is as follows: During the replacement of the rear traction rope of the quay crane trolley, the fixed base 1 of the correction device is installed at the designated position on the lifting brake connecting rod, so that the limit bolt 2 is located at the bottom of the lifting brake connecting rod. After the fixed base 1 is installed in place, the limit bolt 2 is first tightened. The vertical movement of the fixed base 1 is restricted by the cooperation between the limit bolt 2 and the lifting brake connecting rod. Then, the tightening bolt 3 is tightened so that the tightening bolt 3 is pressed against the side of the lifting brake connecting rod to fix the position of the fixed base 1. This places the traction rope at the roller 6, avoiding contact between the rear traction rope and the lifting brake connecting rod, thus ensuring the safety and stability of the trolley's rear traction rope during the replacement process.

[0031] Example 2 In a typical embodiment of this utility model, such as Figure 2 and Figure 3 As shown, a traction rope correction device for a quay crane trolley is proposed, comprising: a fixed base 1, a limiting bolt 2, a tightening bolt 3, a support seat 5, and a roller 6. The limiting bolt 2 and the tightening bolt 3 are both threadedly connected to the fixed base 1 to fix the position of the fixed base 1. The support seat 5 is installed on the fixed base 1 through an adjusting seat 8 and is used to support the roller 6. The roller 6 is rotatably mounted on the support seat 5 through a rotating shaft 7. The support seat 5 and the adjusting seat 8 are movably connected, allowing the lateral position of the support seat 5 to be adjusted as needed.

[0032] Specifically, the fixed base 1 is an inverted U-shaped structure. The fixed base 1 includes a first horizontal plate 14 and a first vertical plate 13. There are two first vertical plates 13, and the two first vertical plates 13 are arranged opposite to each other. The tops of the two first vertical plates 13 are fixedly connected together through the first horizontal plate 14. The inverted U-shaped structure makes it easy to fasten the fixed base 1 to the connecting rod of the lifting brake, which facilitates the connection between the fixed base 1 and the connecting rod of the lifting brake.

[0033] Two through holes 15 are vertically spaced along the first vertical plate 13 of the fixed base 1. A nut 4 is welded and fixed at each through hole 15. The nut 4 is used for threaded connection with the limit bolt 2 and the tightening bolt 3.

[0034] like Figure 2As shown, the support base 5 has a U-shaped structure. The support base 5 includes a second horizontal plate 17 and a second vertical plate 16. There are two second vertical plates 16, which are arranged opposite to each other. The bottoms of the two second vertical plates 16 are welded and fixed together by the second horizontal plate 17. The second horizontal plate 17 of the support base 5 is perpendicular to the first horizontal plate 14 of the fixed base 1, that is, arranged in a cross shape. The roller 6 is rotatably arranged between the two second vertical plates 16 of the support base 5 through the rotating shaft 7.

[0035] The adjusting seat 8 is fixedly installed on the top of the fixed base 1 by welding or other methods. The adjusting seat 8 has a rectangular base structure, such as... Figure 3 As shown, the top of the adjusting seat 8 is provided with a sliding groove 12, which extends along the axial direction of the roller 6. A screw 9 is rotatably provided in the sliding groove 12. A slider 11 is fixedly provided at the bottom of the support seat 5. The slider 11 is sleeved on the screw 9 and is threadedly connected to the screw 9. The slider 11 is slidably disposed in the sliding groove 12.

[0036] In this embodiment, both the slider 11 and the groove 12 have rectangular cross-sections, so that when the screw 9 is rotated, the slider 11 can be driven to move along the groove 12, thereby driving the support seat 5 to move, so as to adjust the lateral position of the roller 6. This facilitates practical use, and when there is an error in the installation position of the correction device, there is no need to repeatedly disassemble and install the correction device.

[0037] It is understandable that the screw 9 can be rotatably mounted in the slide groove 12 via a bearing. This is a conventional technical method, and the specifics will not be elaborated on here.

[0038] To facilitate the driving of the screw 9, in this embodiment, a handle 10 is fixedly connected to one end of the screw 9 so that the screw 9 can be driven to rotate around the axis through the handle 10.

[0039] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
