Description

Technical Field

[0001] This utility model relates to the field of idler support technology, and in particular to a storage bracket for idler rollers of quay crane lifting wire ropes. Background Technology

[0002] Container terminal quay cranes require continuous operation, leading to frequent replacements of their lifting wire rope idlers due to high-frequency stress. Currently, the industry lacks dedicated storage facilities for these idlers, and they are often stored on temporary assembly racks or simply piled up in unused areas of the quay crane's main machine room. However, the movement of the quay crane can easily cause the idlers to shift, increasing the time and cost for maintenance personnel to locate them. Furthermore, the possibility of idlers slipping and causing safety accidents is high. Exposed idlers are also susceptible to contamination from dust, oil, and other pollutants, affecting their subsequent performance.

[0003] In existing related technologies, such as Chinese Patent No. CN217516425U, a movable idler roller bracket for winch wire ropes is disclosed. The core function of this bracket is to horizontally support the wire rope when the winch is working, and to extend the service life of the idler roller by adjusting the friction position between the idler roller and the wire rope. It is a functional support device in the working state. This bracket is only suitable for winch working scenarios and lacks the fixing and protection structures required for idler roller storage. It cannot meet the storage needs of quay crane hoisting wire rope idler rollers in the non-working state, and it is difficult to solve the technical problem of inconvenient storage of quay crane idler rollers.

[0004] Currently, the retrieval and storage of hoisting wire rope idlers for quay cranes still relies on the experience of maintenance personnel for manual handling. This is not only inefficient but also carries the risk of damage to the idlers during transport, further slowing down the quay crane maintenance process. Therefore, the industry urgently needs a storage rack specifically designed for hoisting wire rope idlers for quay cranes to achieve secure fixing, convenient retrieval and storage, and pollution protection of the idlers, thereby improving the standardization and safety of quay crane maintenance operations. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing idler roller supports, such as low handling efficiency, poor stability and safety, and to provide a storage support for quay crane lifting wire rope idlers.

[0006] This utility model is achieved through the following technical solution: a storage bracket for wire rope idlers of a quay crane, comprising a base; a rotatable support frame is provided on the top of the base, the support frame comprising a support plate and two upright plates; the support plate is rotatably connected to the top of the base, and the two upright plates are respectively connected to both ends of the support plate, the support plate and the two upright plates together forming a U-shaped space for storing wire rope idlers; the top of the upright plates is provided with U-shaped insertion holes adapted to the central axis of the wire rope idler, the wire rope idler is placed inside the U-shaped space, and both ends of the central axis are respectively inserted into the two U-shaped insertion holes; a pin mechanism is provided between the upright plates and the base, the position of the support frame can be fixed by the pin mechanism.

[0007] A further improvement of this utility model is that the support plate is provided with an assembly hole, the assembly hole is provided with a connecting bearing, the top of the base is provided with a vertical shaft adapted to the connecting bearing, and the base and the support plate are rotatably connected to the connecting bearing through the vertical shaft.

[0008] A further improvement of this utility model is that the assembly hole is a blind hole, the outer ring of the connecting bearing is interference-fitted with the assembly hole, and the inner ring of the connecting bearing is interference-fitted with the vertical shaft.

[0009] A further improvement of this utility model is that the pin mechanism includes a movable rod, a pin seat, and a pin hole. The movable rod is mounted on the upright plate through the pin seat, and the pin hole is a blind hole located at the top of the base corresponding to the position of the movable rod.

[0010] A further improvement of this utility model is that a magnetic seat A is provided on the upright plate, located directly above the movable rod. After the movable rod is pulled out of the pin hole, the magnetic seat A can fix the position of the movable rod.

[0011] A further improvement of this utility model is that a magnetic base B is provided at the bottom of the pin hole, and the magnetic base B can fix the position of the movable rod after the movable rod is inserted into the pin hole.

[0012] A further improvement of this utility model is that the base is mounted on the trolley, and the base is detachably connected to the trolley chassis by bolts.

[0013] A further improvement of this utility model is that the top of the trolley chassis is provided with an assembly groove that matches the base, and the base is disposed inside the assembly groove.

[0014] A further improvement of this utility model is that the end of the assembly groove away from the trolley handle is provided with an open insertion port, through which the base can be slidably inserted into the assembly groove.

[0015] A further improvement of this utility model is that a protective cover is provided on the outside of the support frame to cover the wire rope idler roller, and the protective cover is detachably connected to the top of the base by bolts.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are: 1. This bracket, through the U-shaped space enclosed by the support plate and the upright plate, and the U-shaped insertion at the top of the upright plate, can provide stable support and limit the movement of the wire rope idler. In conjunction with the pin mechanism to fix the rotatable support frame, it effectively prevents the idler from shifting and slipping during storage. The 360° rotating structure also breaks the limitation of the retrieval and storage angle, allowing maintenance personnel to conveniently retrieve and place the idler without adjusting their own position, greatly improving operational flexibility.

[0017] 2. This bracket adapts the base to the trolley chassis via an assembly groove, allowing the entire unit to be moved to accommodate different maintenance locations on the quay crane. The insertion port design of the assembly groove simplifies the base assembly and disassembly process, eliminating the need for precise alignment of bolt holes or lifting the base. This reduces labor intensity, while the detachable connection also facilitates individual maintenance of the base, enhancing the overall practicality of the bracket.

[0018] 3. This bracket can isolate dust, oil and other contaminants through the protective cover, preventing the service life of the idler rollers from being shortened due to exposure during storage. This is a protective function not covered in the existing technology. At the same time, the magnetic seat provides dual positioning for the movable rod of the pin mechanism, which can prevent the movable rod from shaking and being lost or accidentally dislodged, further avoiding safety hazards during storage and operation, making the storage of quay crane idler rollers more standardized and safe.

[0026] 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.

[0027] Now refer to Figure 1-5 The following is a description of a specific embodiment: The present invention provides a storage bracket for steel wire rope idlers used in quay crane lifting, comprising a base 1; a rotatable support frame 2 is provided on the top of the base 1, the support frame 2 comprising a support plate 201 and two upright plates 202; the support plate 201 is rotatably connected to the top of the base 1, and the two upright plates 202 are respectively connected to both ends of the support plate 201, the support plate 201 and the two upright plates 202 together forming a U-shaped space 3 for storing steel wire rope idlers 4; the top of the upright plate 202 is provided with a U-shaped insertion port 2021 adapted to the central axis 401 of the steel wire rope idler 4, the steel wire rope idler 4 is placed inside the U-shaped space 3, and both ends of the central axis 401 are respectively inserted into the two U-shaped insertion ports 2021; a pin mechanism 5 is provided between the upright plate 202 and the base 1, the position of the support frame 2 can be fixed by the pin mechanism 5.

[0028] In use, the support frame 2 can be rotated to an angle that facilitates the placement and removal of the idler rollers by means of the rotating connection structure between the support frame 2 and the top of the base 1. Then, the hoisting wire rope idler roller 4 is placed into the U-shaped space 3 enclosed by the support plate 201 and the two upright plates 202, so that the two ends of the central shaft 401 of the wire rope idler roller 4 are inserted into the U-shaped sockets 2021 at the top of the two upright plates 202. The initial positioning of the wire rope idler roller 4 is achieved by using the limiting effect of the U-shaped sockets 2021 on the central shaft 401. After the wire rope idler roller 4 is placed or the support frame 2 is rotated to the target position, the pin mechanism 5 between the upright plate 202 and the base 1 is inserted and fixed to restrict the rotational freedom of the support frame 2.

[0029] This bracket solves the problem of limited retrieval angle of the wire rope roller 4 through the rotatable support frame 2. The cooperation between the U-shaped space 3 and the U-shaped socket 2021 can stably support the wire rope roller 4 and prevent the wire rope roller 4 from shifting and slipping during storage. The pin mechanism 5 further fixes the position of the support frame 2, effectively solving the shortcomings of traditional temporary storage of rollers, such as easy shifting and poor safety, and improving the stability and retrieval convenience of the wire rope roller 4.

[0030] Specifically, refer to Figure 2 and Figure 3 The support plate 201 has an assembly hole 2011, and a connecting bearing 8 is provided inside the assembly hole 2011. The top of the base 1 is provided with a vertical shaft 7 that is adapted to the connecting bearing 8. The base 1 and the support plate 201 are rotatably connected to the connecting bearing 8 through the vertical shaft 7. The assembly hole 2011 is a blind hole. The outer ring of the connecting bearing 8 is interference-fitted with the assembly hole 2011, and the inner ring of the connecting bearing 8 is interference-fitted with the vertical shaft 7.

[0031] The rotation of the support plate 201 and the base 1 is achieved through the vertical shaft 7 and the connecting bearing 8. The vertical shaft 7 at the top of the base 1 is interference-fitted with the inner ring of the connecting bearing 8 in the mounting hole 2011 of the support plate 201, and the outer ring of the connecting bearing 8 is interference-fitted with the mounting hole 2011. When the support frame 2 needs to be rotated, the support plate 201 can rotate synchronously around the vertical shaft 7 with the inner ring of the connecting bearing 8. The interference fit structure can prevent loosening gaps between the support plate 201 and the vertical shaft 7, and between the connecting bearing 8 and the mounting hole 2011.

[0032] The structure of the vertical shaft 7 and the connecting bearing 8 with the interference fit ensures the smooth rotation of the support frame 2 and prevents shaking or abnormal noise during rotation. Compared with ordinary clearance fit, it greatly improves the firmness and service life of the rotating connection, and ensures that the support frame 2 rotates stably when maintenance personnel retrieve and store the wire rope idler roller 4, avoiding the wire rope idler roller 4 from being bumped due to structural loosening.

[0033] Specifically, refer to Figure 3The pin mechanism 5 includes a movable rod 501, a pin seat 502, and a pin hole 503. The movable rod 501 is mounted on the upright plate 202 via the pin seat 502. The pin hole 503 is a blind hole and is located at the top of the base 1 at a position corresponding to the movable rod 501.

[0034] When it is necessary to rotate the support frame 2, the movable rod 501 on the pin seat 502 is pulled out from the pin hole 503 at the top of the base 1 to release the fixation of the support frame 2; after the support frame 2 is rotated to the target position, the movable rod 501 is inserted into the corresponding pin hole 503 along the pin seat 502, and the rotation of the support frame 2 is restricted by the cooperation between the movable rod 501 and the pin hole 503; the pin hole 503 is set as a blind hole to avoid the movable rod 501 from penetrating the base 1 too much when inserted, which would cause structural interference.

[0035] The movable rod 501 and the pin seat 502 of the aforementioned pin mechanism 5 cooperate with the blind hole pin hole 503, making operation simple and convenient. It can quickly fix and unlock the support frame 2. Compared with traditional bolt fixing, the operation can be completed without tools, which greatly shortens the preparation time for the steel wire rope roller 4 to be retrieved and stored. The blind hole design avoids the problem of the movable rod 501 falling off or structural interference, thus improving the safety of use.

[0036] Specifically, refer to Figure 3 The upright plate 202 is provided with a magnetic seat A9 located directly above the movable rod 501. After the movable rod 501 is pulled out of the pin hole 503, the magnetic seat A9 can fix the position of the movable rod 501. The bottom of the pin hole 503 is provided with a magnetic seat B901. After the movable rod 501 is inserted into the pin hole 503, the magnetic seat B901 can fix the position of the movable rod 501.

[0037] When the movable rod 501 is pulled out to rotate the support frame 2, the movable rod 501 can be attracted to the magnetic seat A9 on the upright plate 202, and the position of the movable rod 501 is fixed by magnetic force to prevent the movable rod 501 from swinging freely and affecting the operation; when the movable rod 501 is inserted into the pin hole 503 to fix the support frame 2, the magnetic seat B901 at the bottom of the pin hole 503 will attract the end of the movable rod 501, so that the movable rod 501 is kept in the inserted state, and the movable rod 501 is prevented from accidentally coming out due to vibration.

[0038] This bracket solves the problems of the movable rod 501 not having a fixed position after being pulled out, being easy to lose or shake, through the design of the magnetic suction base A9, and enhances the fixed reliability of the movable rod 501 after it is inserted through the design of the magnetic suction base B901. The dual magnetic positioning further improves the ease of use and stability of the pin mechanism 5, reduces the operation steps for maintenance personnel to retrieve and store the wire rope roller 4, and improves work efficiency.

[0039] In one embodiment, reference Figure 4 The base 1 is mounted on the trolley and is detachably connected to the trolley chassis 6 by bolts. The top of the trolley chassis 6 is provided with an assembly groove 601 that is adapted to the base 1, and the base 1 is located inside the assembly groove 601.

[0040] The base 1 is initially positioned by the mounting groove 601 on the top of the trolley chassis 6. After the base 1 is placed into the mounting groove 601, it is detachably fixed by bolts passing through the connection holes between the base 1 and the trolley chassis 6. When it is necessary to move the storage position of the wire rope roller 4, pushing the trolley will move the base 1 and the wire rope roller 4 as a whole. If it is necessary to remove the base 1, the bolts can be loosened and the base 1 can be taken out from the mounting groove 601.

[0041] The design of the trolley chassis 6 enables the bracket to move as a whole, solving the problem that traditional fixed storage brackets cannot adapt to different maintenance positions of the quay crane. The mounting groove 601 can quickly position the base 1, preventing the base 1 from shifting on the trolley. The detachable bolt connection facilitates the individual maintenance or replacement of the base 1, improving the versatility and maintenance convenience of the bracket.

[0042] In one embodiment, reference Figure 4 The assembly groove 601 has an open insertion port 6011 at one end away from the trolley handle 602, and the base 1 can be slidably inserted into the assembly groove 601 through the insertion port 6011.

[0043] When installing base 1, there is no need to precisely align the bolt holes. Base 1 can be slid into the mounting groove 601 from the open insertion port 6011 at the end of the mounting groove 601 away from the trolley handle 602. After base 1 is slid to the appropriate position in the groove, it can be fixed with bolts. When removing base 1, loosen the bolts and slide base 1 out from insertion port 6011.

[0044] This bracket simplifies the assembly process of the base 1 and the trolley chassis 6 through the open insertion port 6011. Compared with the top snap-fit ​​installation in the prior art, it can be slid in and assembled without lifting the base 1, which reduces the labor intensity of installation and avoids the problem of difficult bolt hole alignment. It also significantly shortens the installation time of the base 1 and improves the assembly efficiency of the bracket.

[0045] In one embodiment, specifically, refer to Figure 5 The outer side of the support frame 2 is provided with a protective cover 10 that can cover the wire rope roller 4. The protective cover 10 is detachably connected to the top of the base 1 by bolts.

[0046] After the wire rope idler roller 4 is placed into the U-shaped space 3 of the support frame 2, the protective cover 10 is placed on the outside of the support frame 2. The protective cover 10 is detachably connected to the top of the base 1 by bolts. The protective cover 10 can cover the entire wire rope idler roller 4, preventing external dust, oil and other pollutants from contacting the wire rope idler roller 4. When it is necessary to remove or put away the wire rope idler roller 4, the protective cover 10 can be removed by loosening the bolts.

[0047] This bracket effectively isolates contaminants through the design of the protective cover 10, solving the problem in the prior art where exposed storage of wire rope rollers 4 is prone to dust and oil stains, leading to a shortened service life. The detachable design does not affect the normal handling of wire rope rollers 4. Compared with the fixed protective structure, it takes into account both the pollution protection of wire rope rollers 4 and the convenience of handling, extending the secondary use cycle of wire rope rollers 4.

[0048] 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.
