Description

Technical Field

[0001] This application relates to the field of anti-winding technology for gantry crane wire ropes, and in particular to an anti-winding device for the wire rope at the head of the gantry crane's trunk. Background Technology

[0002] Gantry cranes are key equipment in modern logistics, ports, shipbuilding, and other industries. Their core function is to efficiently and safely lift, load, unload, and stack heavy cargo. Through different structural designs (such as the luffing system and rotating mechanism), they can adapt to various complex working conditions, making them an indispensable piece of mechanical equipment for handling large cargo.

[0003] However, in actual use, during the closing process of the grab bucket at the bottom of the bin, the operator loosened the support wire rope too much, causing the opening and closing wire rope to become entangled with the support wire rope. During rapid lifting, the support wire rope was forcibly pulled into the protective cover of the opening and closing wire rope. At this time, the support wire rope was subjected to very complex forces. Under the combined action of tension, pressure and shear force, the support wire rope broke rapidly. Utility Model Content

[0004] To reduce the possibility of wire rope breakage, this application provides a device for preventing the wire rope from tangling around the head of a gantry crane's trunk beam.

[0005] The anti-entanglement device for the steel wire rope at the elephant trunk head of a gantry crane provided in this application adopts the following technical solution:

[0006] A device for preventing the steel wire rope from tangling around the trunk head of a gantry crane includes a housing body. The housing body has two arc-shaped grooves, which are respectively located on both sides of the housing body. An arc-shaped baffle is installed between the two arc-shaped grooves.

[0007] By adopting the above technical solution, the anti-winding device for the steel wire rope at the gantry crane's trunk beam head effectively prevents the steel wire rope from winding during operation by setting two arc-shaped grooves on the housing body and installing an arc-shaped baffle between the two arc-shaped grooves. The design of the arc-shaped grooves provides a clear running path for the steel wire rope, reducing the possibility of the steel wire rope deviating from the normal track. The arc-shaped baffle further blocks the mutual interference between the steel wire ropes, thereby significantly reducing the risk of the support steel wire rope and the opening and closing steel wire rope winding together, and improving the safety and stability of the gantry crane's operation.

[0008] In one specific implementation scheme, it further includes a transverse steel edge, wherein at least two sets of transverse steel edges are provided, and the transverse steel edges are respectively installed at both ends of the arc groove in the length direction. The transverse steel edges are set according to the width of the cover body, and the distance between adjacent transverse steel edges at both ends of the arc groove in the length direction is not less than the length of the arc groove.

[0009] By adopting the above technical solution, the transverse steel edging effectively enhances the structural strength of the casing body, preventing deformation caused by external forces during use. Specifically, the transverse steel edging is installed at both ends along the length of the arc-shaped groove, with a spacing not less than the length of the arc-shaped groove. This design forms a stable support structure, preventing the wire rope from deviating from its predetermined trajectory during operation, thereby reducing the risk of wire rope entanglement. Furthermore, the transverse steel edging is positioned corresponding to the width of the casing body, further improving the overall structural stability and ensuring good performance of the device under complex working conditions.

[0010] In one specific implementation, a trapezoidal baffle is also included, which is installed on the upper transverse steel edging and is arranged along the length of the transverse steel edging.

[0011] By adopting the above technical solution, the trapezoidal baffle is installed on the upper transverse steel edge and is set along the length of the transverse steel edge, which can effectively prevent the opening and closing wire rope from tangling with the support wire rope. Combined with the overall solution, the design of the arc-shaped groove and arc-shaped baffle provides a clear running path for the wire rope, while the transverse steel edge further restricts the range of motion of the wire rope. The addition of the trapezoidal baffle enhances the guiding and isolation effect on the wire rope, thereby significantly reducing the risk of wire rope entanglement and ensuring the safety and stability of the gantry crane during hoisting operations.

[0012] In one specific implementation scheme, one end of the arc-shaped baffle is fixedly connected to the middle part of the trapezoidal baffle.

[0013] By adopting the above technical solution, the design of fixing one end of the arc-shaped baffle to the middle part of the trapezoidal baffle enhances the guiding and protection effect of the wire rope, and improves the stability and reliability of the device.

[0014] In one specific implementation scheme, the system further includes arc-shaped steel edging, wherein at least four sets of arc-shaped steel edging are provided, and the arc-shaped steel edging are respectively installed on both sides of the arc groove width direction. The spacing between adjacent steel edgings on both sides of the same arc groove width direction is not less than the length of the arc groove.

[0015] By adopting the above technical solution, the arc-shaped extended steel edging effectively prevents the wire rope from deviating and tangling in the width direction of the arc groove, avoiding breakage due to complex stress. Specifically, at least four sets of arc-shaped extended steel edgings are installed on both sides of the arc groove width direction, ensuring the guiding and limiting function of the wire rope. Simultaneously, the distance between adjacent extended steel edgings on both sides of the same arc groove width direction is not less than the length of the arc groove, further enhancing the protection of the wire rope and reducing friction and interference between the wire rope and other components of the device. This improves the overall reliability and safety of the anti-tangling device for the wire rope at the gantry crane's trunk beam head.

[0016] In one specific implementation scheme, the arc-shaped baffle includes a plate and a baffle edge with steel trim. The plate is installed between two arc-shaped grooves, and the width of the plate gradually decreases from the higher end to the lower end. The baffle edge with steel trim is installed on the side of the plate away from the cover body.

[0017] By adopting the above technical solution, the arc-shaped baffle is composed of a plate and a steel edging. The plate is installed between two arc-shaped grooves, and the width of the plate gradually decreases from the higher end to the lower end. This design can effectively guide the movement path of the steel wire and prevent the steel wire from deviating from the normal track and becoming entangled. At the same time, the steel edging is installed on the side of the plate away from the cover body, further enhancing the limiting effect on the steel wire and preventing the steel wire from jumping out of the arc-shaped groove area. This significantly improves the reliability and safety of the anti-entanglement device for the steel wire rope at the elephant trunk head of the gantry crane.

[0018] In one specific implementation scheme, a plurality of through holes are sequentially formed on the plate along the arc direction.

[0019] By adopting the above technical solution, several through holes are sequentially opened on the plate of the arc-shaped baffle along the arc direction, which can effectively reduce the overall weight of the arc-shaped baffle, thereby reducing the load on the housing body during installation and use. At the same time, the through-hole design helps to optimize material distribution, reducing manufacturing costs while ensuring structural strength. In addition, the through-holes can also improve air circulation, reduce swaying caused by air resistance, and further enhance the stability and reliability of the anti-winding device for the steel wire rope at the gantry crane's trunk beam head in actual working conditions.

[0020] In one specific implementation scheme, reinforcing ribs are installed on both sides of the housing body, and the reinforcing ribs are provided with several threaded holes for fixing.

[0021] By adopting the above technical solution, the addition of reinforcing ribs significantly improves the structural strength of the housing body, effectively preventing deformation caused by external impacts or gravity during use, thereby ensuring the overall stability of the device. The threaded holes facilitate the fixed connection between the reinforcing ribs and the housing body, simplifying the installation process, improving assembly efficiency, enhancing connection reliability, and further extending the service life of the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting arc-shaped grooves and arc-shaped baffles on the housing body, the opening and closing wire ropes and the support wire ropes are effectively prevented from getting tangled, and the support wire ropes are prevented from being forcibly pulled into the protective cover of the opening and closing wire ropes, thus significantly reducing the risk of wire rope breakage.

[0024] 2. The design of the arc groove and arc baffle can guide the wire rope to move along a predetermined path, reduce mutual interference of the wire rope under complex working conditions, and improve the stability and safety of the gantry crane operation;

[0025] 3. The structure is simple and easy to install, and it can effectively protect the wire rope without changing the existing main structure of the gantry crane, thereby reducing maintenance costs and improving operational efficiency. Attached Figure Description

[0028] This application discloses an anti-entanglement device for the steel wire rope at the head of a gantry crane's trunk.

[0029] Figure 1 As shown, the anti-winding device for the steel wire rope at the head of the gantry crane's trunk beam includes a housing body 1, an arc-shaped baffle 2, and a transverse steel edging 3. Arc-shaped grooves 11 are formed on both sides of the arc-shaped sidewall of the housing body 1, and the transverse steel edging 3 is installed on both sides along the length of the arc-shaped grooves 11, forming a multi-layered protective structure that effectively reduces the risk of steel wire rope entanglement and improves overall safety.

[0030] The housing body 1 is made of high-strength steel plate, possessing excellent impact resistance and wear resistance. Its semi-enclosed arc-shaped structure better accommodates the installation requirements of the gantry crane's trunk-like head. The arc-shaped groove 11 is machined using a cutting process, with its edges chamfered to avoid unnecessary damage to the wire rope. For example, the arc-shaped groove 11 can be processed using laser cutting or CNC machine tools to ensure the precision and flatness of the groove opening.

[0031] Two sets of transverse steel edging 3 are provided, and the transverse steel edging 3 are respectively installed at both ends of the arc groove 11 in the length direction. The transverse steel edging 3 is set according to the width of the cover body 1, and the distance between adjacent transverse steel edging 3 at both ends of the arc groove 11 in the length direction is not less than the length of the arc groove 11.

[0032] In this embodiment, a trapezoidal baffle 4 is also included. The trapezoidal baffle 4 is installed on the upper transverse steel edging 3 and is set perpendicular to the protective cover plate. The trapezoidal baffle 4 is installed along the length of the transverse steel edging 3, and a section of the arc-shaped baffle 2 is fixedly connected to the middle part of the trapezoidal baffle 4.

[0033] The arc-shaped baffle 2 is made of wear-resistant material, such as high-molecular-weight polyethylene or stainless steel sheet 21, and its thickness can be adjusted according to actual needs, usually between 5mm and 10mm. One end of the arc-shaped baffle 2 is fixedly connected to the middle part of the trapezoidal baffle 4, and a stable fixation is achieved by welding or bolting. For example, the connection between the arc-shaped baffle 2 and the trapezoidal baffle 4 can be completed by spot welding or double-ended bolts to ensure connection strength and reliability.

[0034] Specifically, the arc-shaped baffle 2 includes a plate 21 and a baffle extension steel edging 22. The plate 21 is installed between the two arc-shaped grooves 11, and its width gradually decreases from the higher end to the lower end, forming a wedge-shaped structure, which can better guide the movement trajectory of the wire rope. The baffle extension steel edging 22 is installed on the side of the plate 21 away from the cover body 1, providing further protection. For example, the plate 21 can be made of aluminum alloy or stainless steel, with a thickness of 6mm to 8mm, and the surface is sandblasted to increase wear resistance and corrosion resistance.

[0035] In this embodiment, the application also includes an arc-shaped steel edge 5, of which four arc-shaped steel edges 5 are provided, and at least four sets of arc-shaped steel edges 5 are provided. The arc-shaped steel edges 5 are respectively installed on both sides of the arc groove 11 in the width direction, and the distance between adjacent steel edges located on both sides of the same arc groove 11 in the width direction is not less than the length of the arc groove 11.

[0036] Reinforcing ribs 6 are added to both sides of the housing body 1, and several threaded holes for fixing are opened on the reinforcing ribs 6. The addition of reinforcing ribs 6 not only enhances the overall rigidity of the housing body 1, but also improves the installation stability of the device, further enhancing the reliability and service life of the device.

[0037] Several through holes are sequentially formed along the curvature direction on the plate 21 of the arc-shaped baffle 2. The through holes not only reduce the overall weight of the device, but also improve ventilation and heat dissipation performance, reducing the risk of deformation of the device due to high temperature.

[0038] The implementation principle of the anti-entanglement device for the steel wire rope at the elephant trunk head of a gantry crane according to this application embodiment is as follows: By setting up a multi-layered protective structure including a cover body 1, an arc-shaped groove 11, an arc-shaped baffle 2, and a transverse steel edging 3, the movement range of the steel wire rope is effectively limited, avoiding direct contact between the opening / closing steel wire rope and the supporting steel wire rope. The wedge-shaped design of the arc-shaped baffle 2 can guide the movement trajectory of the steel wire rope and reduce the possibility of entanglement. At the same time, the multi-layered protective barrier of the transverse steel edging 3 further enhances the reliability of the device and significantly improves the safety of the gantry crane.

[0039] 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.
