A dynamic sealing cable outlet cover for wire ropes and a gantry crane

Abstract

This application relates to a dynamic sealing wire rope exit cover and a gantry crane, belonging to the technical field of lifting equipment. It includes a guide assembly comprising two symmetrically arranged support plates and two rollers mounted side-by-side between the two support plates. The two rollers are spaced apart to form a gap extending axially for the wire rope to pass through. An elastic sealing assembly includes two elastic sealing plates symmetrically installed below the gap. The opposite ends of the two elastic sealing plates are pressed together to form a downward-facing V-shaped structure. When the wire rope passes through, a dynamic opening adapted to the outer contour of the wire rope is formed locally, while the unpassed area remains sealed to prevent rainwater from flowing in. Simultaneously, the gap formed by the two rollers guides the wire rope, facilitating its upward exit and lateral displacement. This achieves dynamic sealing and smooth rope exit, solving the problems of large footprint, poor rope exit smoothness, and easy water accumulation in traditional exit covers.

Description

Technical Field

[0001] This application relates to the field of lifting equipment technology, and in particular to a wire rope dynamic sealing rope outlet cover and a gantry crane. Background Technology

[0002] With the rapid development of the port logistics industry, gantry cranes, as important loading and unloading equipment, directly affect operational efficiency through their performance and reliability. In the design of gantry cranes, the wire rope exit sealing is a crucial aspect, requiring not only to ensure smooth wire rope operation but also to possess excellent waterproof and dustproof capabilities.

[0003] In related technologies, traditional gantry cranes typically employ a disc-shaped cable exit cover. The wire rope passes through a sleeve mounted on the machine room cover, then through a rotatable large and small disc cover, and connects to other mechanisms. While this structure fulfills basic functions, it presents several problems in practical applications. For example, the disc structure occupies a large volume, potentially affecting the arrangement of other components; when the drum length is long, the volume of the large disc cover increases significantly, leading to a shift in the center of gravity, making rotation difficult, and consequently affecting the smoothness of the wire rope exit.

[0004] Furthermore, the large surface area of ​​the disc-shaped rope exit cover makes it prone to water accumulation, especially during rainy weather. This water accumulation can further exacerbate wear or corrosion of rotating parts, reducing the equipment's lifespan. Therefore, a new type of rope exit cover structure is urgently needed to solve these problems and improve the practicality and reliability of gantry cranes. Summary of the Invention

[0005] In response to the shortcomings or deficiencies mentioned in the background technology above, this application provides a wire rope dynamic sealing rope outlet cover and a gantry crane to solve the problems of large volume, poor rope outlet smoothness and easy water accumulation of traditional rope outlet covers in related technologies.

[0006] In a first aspect, embodiments of this application provide a dynamic sealing cable outlet cover for a wire rope, comprising:

[0007] The guide assembly includes two symmetrically arranged support plates and two rollers mounted side by side between the two support plates, the two rollers being spaced apart to form a gap extending axially and through which a wire rope passes.

[0008] The elastic sealing assembly includes two elastic sealing plates disposed below the gap and symmetrically installed. The opposite ends of the two elastic sealing plates are pressed together to seal and form a V-shaped structure with the opening facing downward.

[0009] In one aspect, in some embodiments, the opposite ends of the two elastic sealing plates are bent upward to form lips that fit together and seal against each other, the length of which is greater than the length of the gap.

[0010] In one aspect, some embodiments further include a cylinder for connecting to the roof of the machine room, the cylinder being located below the V-shaped structure, and two support plates being rotatably connected to the cylinder with their rotation axes coaxial.

[0011] In one aspect, in some embodiments, the guide assembly further includes two connecting plates that connect the two support plates into one unit, and the two connecting plates and the two support plates together form a rigid frame structure.

[0012] In one aspect, in some embodiments, the two connecting plates are spaced apart and symmetrically arranged, and the two elastic sealing plates are respectively connected to the two connecting plates and cover the upper opening formed by the two connecting plates.

[0013] In some embodiments, a pressure strip is fixedly installed on the connecting plate by fasteners. The pressure strip is used to press the elastic sealing plate onto the connecting plate so that the elastic sealing plate is sealed to the connecting plate.

[0014] In some embodiments, the support plate, connecting plate, and elastic sealing plate together form a cover structure, the opening of which faces downward and covers the upper opening of the cylinder.

[0015] In one aspect, in some embodiments, the connecting plate includes a vertical plate and an inclined plate connected to each other, the inclined plate being located above the cylinder and connected to the elastic sealing plate, and the vertical plate being parallel to and spaced apart from the outer wall of the cylinder.

[0016] In some embodiments, the tilt angle of the inclined plate is consistent with the tilt angle of the elastic sealing plate.

[0017] Secondly, embodiments of this application provide a gantry crane, comprising:

[0018] The wire rope dynamic sealing rope cover described in any of the above items.

[0019] The beneficial effects of the technical solution provided in this application include:

[0020] This application provides a wire rope dynamic sealing rope outlet cover and a gantry crane. The guide assembly includes two symmetrically arranged support plates and two rollers mounted side by side between the two support plates. The two rollers are spaced apart to form a gap that extends axially and allows the wire rope to pass through. The elastic sealing assembly includes two elastic sealing plates disposed below the gap and symmetrically installed. The opposite ends of the two elastic sealing plates are pressed together to seal and form a V-shaped structure with the opening facing downward.

[0021] Therefore, when the wire rope passes through upwards, the local area where the two elastic sealing plates meet can form a dynamic opening that matches the outer contour of the wire rope. The area not passed through remains sealed to prevent rainwater from flowing in. At the same time, the gap formed by the two rollers can guide the wire rope, making it easier for the wire rope to pass through and move laterally. This achieves dynamic sealing and smooth rope exit, solving the problems of large footprint, poor rope exit smoothness, and easy water accumulation of traditional rope exit covers.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In response to the shortcomings or deficiencies mentioned in the background technology above, this application provides a wire rope dynamic sealing rope outlet cover and a gantry crane to solve the problems of large volume, poor rope outlet smoothness and easy water accumulation of traditional rope outlet covers in related technologies.

[0031] See Figures 1 to 4 As shown, the first aspect of this application provides a dynamic sealing cable outlet cover for a wire rope, comprising:

[0032] The guide assembly includes two symmetrically arranged support plates 1 and two rollers 2 mounted side by side between the two support plates 1. The two rollers 2 are spaced apart to form a gap 3 that extends axially and allows the wire rope 9 to pass through.

[0033] The elastic sealing assembly includes two elastic sealing plates 4 disposed below the gap 3 and symmetrically installed. The opposite ends of the two elastic sealing plates 4 are pressed together to seal and form a V-shaped structure with the opening facing downward.

[0034] The wire rope dynamic sealing exit cover of this application embodiment achieves dynamic sealing and smooth exit of the wire rope 9 by setting a guide component and an elastic sealing component. The two rollers 2 of the guide component form a gap 3, allowing the wire rope 9 to pass through upwards and move laterally. At the same time, the two elastic sealing plates 4 of the elastic sealing component ensure sealing through dynamic contact, solving the problems of large footprint, poor rope exit smoothness, and easy water accumulation of traditional exit covers.

[0035] For example, the two ends of the roller shafts of the two rollers 2 are respectively fixedly mounted on the two side support plates 1. The two rollers 2 can rotate around their own roller shafts. The two rollers 2 are arranged laterally on the same plane, with parallel and adjacent axes. The two rollers 2 are spaced apart by a gap 3 extending along the axial direction of the rollers 2. The width of the gap 3 is configured to allow the wire rope 9 to pass through and move laterally.

[0036] The elastic sealing plate 4 is made of rubber. Two rubber plates are tilted and spliced ​​together and located directly below the gap 3. The two ends of the rubber plates can be fixed on the support plate 1, or additional brackets can be installed for fixing. The tops of the two rubber plates are pressed together to seal and form a V-shaped structure with the opening facing downward, which facilitates rainwater to slide off from both sides.

[0037] The tops of the two rubber plates press against each other in a natural state to achieve a planar fit and seal. When the steel wire rope 9 passes through upwards, a dynamic opening is formed locally that matches the outer contour of the steel wire rope 9. The area not passed through maintains a sealed contact to prevent rainwater from flowing in.

[0038] During rope delivery, the wire rope 9 moves with the crane's own winch drum, and its position changes horizontally. At this time, the entire moving range of the wire rope 9 is within the rope delivery cover, preventing it from being pulled and causing jamming. A rolling bearing is installed between the guide roller 2 and its own shaft. During rope delivery, the wire rope 9 drives the roller 2 to rotate, avoiding friction between the wire rope 9 and the guide roller 2.

[0039] It should be noted that traditional rope exit covers are generally disc-shaped and occupy a large volume; the rope exit cover of this application is elongated and occupies less space. Furthermore, the center of gravity of a traditional rope exit cover is far from its axis of rotation, causing it to jam during rotation and affecting the exit of the wire rope 9; the rope exit cover of this application has two rollers 2, with the wire rope 9 always positioned between the two rollers 2, resulting in less overall rotation of the rope exit cover and smoother wire rope exit. Moreover, traditional rope exit covers are bulky and prone to water accumulation during rain, while the rope exit cover of this application is smaller and less prone to water accumulation.

[0040] Firstly, in some alternative embodiments: see Figures 1 to 4 As shown in the figure, this application embodiment provides a wire rope dynamic sealing rope outlet cover. The two elastic sealing plates 4 of the wire rope dynamic sealing rope outlet cover are bent upward at opposite ends to form a lip 5 that fits and seals with each other. The length of the lip 5 is greater than the length of the gap 3.

[0041] The dynamic sealing cable cover of this embodiment further enhances the sealing effect by setting an upwardly curved lip structure. The length of the lip 5 is greater than the length of the gap 3, ensuring that the wire rope 9 remains sealed during movement, preventing rainwater or dust from entering.

[0042] For example, the elastic sealing plate 4 can be made of rubber, silicone or polyurethane, all of which are soft and elastic, allowing the steel wire rope 9 to pass through the joint of the two elastic sealing plates 4, while other parts can fit together naturally to prevent rainwater from flowing in.

[0043] Firstly, in some alternative embodiments: see Figures 1 to 4 As shown in the figure, this application embodiment provides a wire rope dynamic sealing rope outlet cover, which also includes a cylinder 6 for connecting to the machine room roof 10. The cylinder 6 is located below the V-shaped structure, and two support plates 1 are rotatably connected to the cylinder 6 and their rotation axes are coaxial.

[0044] The wire rope dynamic sealing rope outlet cover of this application embodiment is provided with a cylinder 6 connected to the machine room roof 10 and a rotating connection method, so that the support plate 1 can swing and adjust the angle with the direction of wire rope 9 outlet, avoiding structural interference and improving adaptability.

[0045] Specifically, the cylinder 6 is fixedly installed on the roof 10 of the machine room and connected to the rope outlet. The support plate 1 is hinged to the side wall of the cylinder 6 through a short shaft. The angle formed by the support plate 1 and the cylinder 6 changes with the direction of the wire rope 9, which can prevent the wire rope 9 from bending and deforming the rope outlet cover during the rope outlet process.

[0046] Firstly, in some alternative embodiments: see Figures 1 to 4As shown, this application embodiment provides a wire rope dynamic sealing rope exit cover. The guide component of the wire rope dynamic sealing rope exit cover also includes two connecting plates 7 that connect two support plates 1 into one piece. The two connecting plates 7 and the two support plates 1 together form a rigid frame structure.

[0047] In this embodiment, the wire rope dynamic sealing rope cover uses connecting plates 7 to fix the support plate 1 into a rigid frame, which enhances the overall structural strength, ensures the stability of the guide assembly and the elastic sealing assembly, and reduces the risk of deformation. For example, both the connecting plate 7 and the support plate 1 can be made of steel plates. The two ends of the two connecting plates 7 are welded and fixed to the two support plates 1 respectively, forming a rigid rectangular frame with the support plates 1.

[0048] Firstly, in some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a wire rope dynamic sealing rope outlet cover. The wire rope dynamic sealing rope outlet cover has two connecting plates 7 spaced apart and symmetrically arranged. Two elastic sealing plates 4 are respectively connected to the two connecting plates 7 and cover the upper opening formed by the two connecting plates 7.

[0049] The wire rope dynamic sealing rope cover of this application embodiment covers the upper opening formed by two connecting plates 7 with symmetrically arranged elastic sealing plates 4, forming a closed cover structure at the upper end. This can effectively prevent external debris from falling in from above, while facilitating rainwater to slide off, thus optimizing drainage performance.

[0050] Firstly, in some alternative embodiments: see Figures 1 to 4 As shown in the embodiment of this application, a wire rope dynamic sealing rope outlet cover is provided. A pressure strip 8 is fixedly installed on the connecting plate 7 of the wire rope dynamic sealing rope outlet cover by fasteners. The pressure strip 8 is used to press the elastic sealing plate 4 onto the connecting plate 7 so that the elastic sealing plate 4 and the connecting plate 7 are sealed together.

[0051] In this embodiment, the wire rope dynamic sealing cable cover uses a pressure strip 8 and fasteners to fix the elastic sealing plate 4, ensuring a tight fit between the sealing plate and the connecting plate 7, thus preventing seal failure due to vibration or external force. For example, in this embodiment, the pressure strip 8 is made of angle steel and has fastener mounting holes.

[0052] Firstly, in some alternative embodiments: see Figures 1 to 4 As shown in the figure, this application embodiment provides a wire rope dynamic sealing rope outlet cover. The support plate 1, connecting plate 7 and elastic sealing plate 4 of the wire rope dynamic sealing rope outlet cover together form a cover structure. The opening of the cover structure faces downward and covers the upper opening of the cylinder 6.

[0053] The wire rope dynamic sealing rope cover of this embodiment is designed with a downward opening in the cover structure to cover the upper opening of the cylinder 6, which can effectively prevent rainwater from falling into the cylinder 6, and at the same time facilitate maintenance and cleaning.

[0054] Firstly, in some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a wire rope dynamic sealing rope outlet cover. The connecting plate 7 of the wire rope dynamic sealing rope outlet cover includes a vertical plate 71 and an inclined plate 72 connected to each other. The inclined plate 72 is located above the cylinder 6 and connected to the elastic sealing plate 4. The vertical plate 71 is parallel to the outer wall of the cylinder 6 and is spaced apart.

[0055] The wire rope dynamic sealing rope cover of this embodiment optimizes the sealing contact surface by matching the inclined plate 72 with the elastic sealing plate 4, ensuring the reliability of dynamic sealing. At the same time, the vertical plate 71 increases the coverage area of ​​the cover structure, which can effectively prevent rainwater from falling into the cylinder 6. The vertical plate 71 is spaced apart from the outer wall of the cylinder 6, which facilitates the support plate 1 to swing slightly around the cylinder 6.

[0056] For example, the vertical plate 71 and the inclined plate 72 are integrally bent or welded together. It should be noted that the rope cover structure of this application has no large-area horizontal plates; all plates are vertical or inclined, thus making it less prone to water accumulation.

[0057] Firstly, in some alternative embodiments: see Figures 1 to 4 As shown, this application embodiment provides a wire rope dynamic sealing rope outlet cover, wherein the tilt angle of the tilt plate 72 of the wire rope dynamic sealing rope outlet cover is consistent with the tilt angle of the elastic sealing plate 4.

[0058] The wire rope dynamic sealing rope cover of this application embodiment achieves uniform sealing force after the pressure strip 8 is installed by using the angle consistency between the inclined plate 72 and the elastic sealing plate 4. Rainwater can smoothly slide down along the elastic sealing plate 4 and the inclined plate 72, thus extending the service life of the cover structure.

[0059] See Figures 1 to 4 As shown, a second aspect of this application provides a gantry crane, comprising:

[0060] The wire rope dynamic sealing rope cover in any of the above embodiments.

[0061] The gantry crane of this application significantly improves the smoothness and sealing performance of wire rope delivery by adopting the wire rope dynamic sealing rope cover of the above embodiment, while reducing maintenance requirements and improving the overall reliability of the equipment.
