Description

Technical Field

[0001] This invention relates to the field of cable crane technology, and more specifically, to a cable crane. Background Technology

[0002] Cable cranes, as a type of lifting equipment with large spans and heavy tonnage, are widely used in various fields such as bridge construction, port lifting, large equipment installation, and hydropower station construction due to their advantages of wide coverage and strong lifting capacity. With the development of modern engineering construction towards large spans, heavy-duty operations, and multi-area operations, higher requirements are placed on the operational flexibility, structural stability, lifting efficiency, and accuracy of cable cranes.

[0003] Currently, most existing cable cranes adopt a fixed tower structure, with the tower fixedly connected to the foundation. This prevents flexible adjustment of the lifting position according to operational needs. When materials need to be lifted to different locations across a traversed area, it is often necessary to redeploy equipment or build auxiliary lifting facilities. This not only increases construction costs and preparation time but also severely limits operational efficiency, making it difficult to adapt to multi-area, dynamic lifting requirements. Some cable cranes with lateral movement functions have unreasonable lateral movement mechanism designs, often using a single drive method. These mechanisms are prone to jamming and deviation during lateral movement, and the locking structure after lateral movement lacks reliability, posing significant safety hazards and failing to meet the structural stability requirements during the lifting of large-tonnage materials.

[0004] In long-span operations, the tower structure of existing cable cranes is mostly a single column type, lacking effective support and stabilizing structure. When lifting heavy materials or encountering severe weather such as strong winds, the tower is easily subjected to lateral tension and eccentric force, causing it to sway, shift, or even deform. This not only affects the accuracy of material lifting but may also lead to equipment damage and seriously threaten operational safety. Summary of the Invention

[0005] The purpose of this invention is to provide a cable crane that addresses the shortcomings of existing technologies and solves the problems mentioned in the background section.

[0006] The technical solution of this invention is implemented as follows:

[0013] In some technical solutions of the present invention, a support frame is slidably provided in the sinking channel along the vertical direction, and a second hydraulic pushing structure is provided in the sinking channel. The telescopic end of the second hydraulic pushing structure is connected to the support frame. The walking structure is installed in the hollow area inside the support frame. When the first hydraulic pushing structure pushes the walking structure to move to the bottom of the sinking channel, the telescopic end of the second hydraulic pushing structure moves out of its body, and the top of the support frame is embedded in the bottom of the transverse sliding beam.

[0014] In some technical solutions of the present invention, a guide groove is provided on the inner wall of the sinking channel in the horizontal direction, and a limiting groove communicating with the guide groove is provided on the inner wall of the sinking channel in the vertical direction.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] Example This invention provides a cable crane, such as Figures 1-12 As shown, this design aims to solve the technical problems of existing cable cranes, such as the inability to flexibly adjust the working position, insufficient stability during large-span operations, low efficiency in lifting large-tonnage materials, and high resistance during sliding. It mainly includes a load-bearing structure 1, a sliding beam structure 3, a transverse sliding beam 4, a tower 5, a truss 6, a tower crane 7, a loading platform 8, a cable traction structure 9, a locking structure 11, and a hydraulic traction drive structure 12. The specific structure is as follows: This embodiment sets up two sets of load-bearing structures 1, symmetrically arranged on both sides of the work area. Each set of load-bearing structures 1 includes a base 2, which is cast from concrete with a reinforced steel cage. The base 2 is formed by excavating a foundation pit on the basis of the installation in the work area and then casting it, providing a stable support for the entire equipment and ensuring the overall load-bearing capacity of the equipment during the hoisting of large-tonnage materials. The foundation surface of the base 2 needs to be leveled to ensure the flatness and stability of subsequent component installation.

[0035] The sliding beam structure 3 is installed on the foundation surface of the base 2 and is set horizontally. Specifically, it includes two parallel limiting frames 301, each a positioning angle steel. Both limiting frames 301 are fixed to the foundation surface of the base 2 by anchor rods, forming a transverse sliding channel 302 that matches the dimensions of the transverse sliding beam 4. The transverse sliding beam 4 is welded from multiple steel plates. The transverse sliding beam 4 is slidably assembled within the transverse sliding channel 302 and can reciprocate transversely along the extension direction of the channel 302. A guide groove 303 is formed horizontally on the inner side wall of the limiting frame 301, and a limiting groove 304, communicating with the guide groove 303, is formed vertically at an angle. This provides installation and movement space for subsequent auxiliary guiding structures and, in conjunction with locking mechanisms, fixes the transverse sliding beam 4 within the transverse sliding channel 302.

[0036] Two towers 5 are fixedly installed on the transverse sliding beam 4. The two towers 5 are arranged symmetrically, and several trusses 6 are equidistantly arranged between them in the vertical direction. The two ends of the trusses 6 are fixedly connected to the two towers 5 respectively. Through the overall force characteristics of the trusses 6, the longitudinal and transverse forces on the towers 5 are dispersed, which enhances the structural rigidity and stability of the towers 5 and prevents the towers 5 from deforming due to large span and heavy load. This is suitable for large span operation requirements. Both towers 5 are bolted to the bottom of the sliding beam pressure beam. After the transverse sliding beam 4 reaches the preset moving position, the sliding beam pressure beam is fixed to the base 2 by the sliding beam pressure beam anchor rod. The sliding beam pressure beam anchor rod is φ32 precision threaded steel.

[0037] Tower crane 7 is installed in the middle of the transverse sliding beam 4. The main body of tower crane 7 extends outward after passing through several trusses 6, enabling auxiliary material hoisting and fine-tuning of position. Loading platform 8 is fixedly installed on the top of two towers 5. Cable traction structure 9 is installed on each loading platform 8. Several sets of cables are driven between the cable traction structures 9 at both ends of the transverse area. Driven by the cable traction structures 9, the cables form a hoisting channel across the working area, enabling the hoisting of large-tonnage materials.

[0038] A hydraulic traction drive structure 12 is provided on the base 2. This structure is connected to the transverse sliding beam 4 via a steel cable and is used to traction the transverse sliding beam 4 to reciprocate along the transverse channel 302. A locking structure 11 is provided in the transverse channel 302 of the sliding beam structure 3. The locking structure 11 includes several locking rods 1101. Several locking holes are opened on the side walls of the limiting frame 301. A limiting channel is opened on the side wall of the transverse sliding beam 4. After the locking rods 1101 pass through the two coaxial locking holes and the limiting channel, the transverse sliding beam 4 can be locked and fixed on the two limiting frames 301, realizing multiple fixing methods to prevent the transverse sliding beam 4 from being accidentally displaced during operation. The hydraulic traction drive structure 12 includes a tension beam installed on the base 2. The tension beam is equipped with a tension jack, and the steel cable extends outward after passing through the tension jack.

[0039] The base 2 is located in the area of ​​the transverse sliding channel 302 and is provided with a sinking channel 15. A traveling structure 13 is installed between the transverse sliding beam 4 and the displacement seat. An adjusting structure 14 is provided between the traveling structure 13 and the transverse sliding beam 4. The adjusting structure 14 is used to push the traveling structure 13 into the sinking channel 15 and make it contact the inner bottom wall of the sinking channel 15, assisting the transverse sliding beam 4 to move laterally. This avoids uneven local wear of the transverse sliding beam 4 during the transverse movement, which could cause the transverse sliding beam 4 to tilt and affect the cable traction structure 9 formed by the tower 5, resulting in the problem that the hoisting accuracy cannot be guaranteed.

[0040] The adjustment structure 14 includes several mounting cylinders 1401 mounted on the transverse sliding beam 4, each mounting cylinder 1401 containing a first hydraulic pushing structure 1402. A guide cylinder 1403 is rotatably mounted on the frame 1301 within the traveling structure 13. Partial sliding of the guide cylinder 1403 occurs within the mounting cylinder 1401. Two through slots 1404 are symmetrically formed on the outer wall of the mounting cylinder 1401 in the vertical direction, and two locking slots 1405 are formed circumferentially around the mounting cylinder 1401. The locking slots 1405 correspond to their respective through slots 1404 and 1405. An inclined connecting groove 1404 is provided between the two to ensure a smooth transition and connection between them. A bearing column 1406 connected to the guide cylinder 1403 is slidably provided in the groove 1404. The bearing column 1406 passes through the guide cylinder 1403 and extends outward to enhance its rigidity in connection with the guide cylinder 1403. The telescopic end of the first hydraulic pushing structure 1402 is rotatably connected to the guide cylinder 1403 through a load-bearing bearing. The telescopic structure composed of the hydraulic structure, the mounting cylinder 1401 and the guide cylinder 1403 improves the stability of this structure when it is moving.

[0041] A first drive motor 1302 is installed on the frame 1301 of the walking structure 13. An adjustment gear 1407 is installed on the outer wall of the guide cylinder 1403. A drive gear 1303 that meshes with the adjustment gear 1407 is installed on the output end of the first drive motor 1302. This is used to drive the guide cylinder 1403 to rotate, thereby switching the bearing column 1406 between the through groove 1404 and the locking groove 1405 and fixing the position of the walking structure 13.

[0042] A support frame 16 is slidably mounted on the sinking channel 15 in the vertical direction. A second hydraulic pushing structure 17 is mounted on the sinking channel 15 via a slide rail structure. The telescopic end of the second hydraulic pushing structure 17 is connected to the support frame 16. The traveling structure 13 is installed in the hollow area 1601 inside the support frame 16. When the first hydraulic pushing structure 1402 pushes the traveling structure 13 to move to the bottom of the sinking channel 15, the telescopic end of the second hydraulic pushing structure 17 extends, pushing the top of the support frame 16 to be embedded in the bottom of the transverse sliding beam 4, realizing the positioning connection between the support frame 16 and the transverse sliding beam 4, and providing auxiliary support for the transverse sliding beam 4 and the two towers 5. The transverse sliding beam 4 moves from inside the transverse channel 302 along the numerical direction to one-quarter of the height of the transverse channel 302, and most of the transverse sliding beam 4 is located inside the transverse channel 302 to prevent it from shifting and causing a safety accident. When the traveling structure is in stable contact with the sinking channel, the support frame 16 and the transverse sliding beam 4 disengage.

[0043] A slider structure 305 is slidably provided in the limiting groove 304 located inside the limiting frame 301. A long groove 306 is provided on the outer wall of the slider structure 305. A connecting column 1304 connected to the frame 1301 of the walking structure 13 is slidably provided in the long groove 306, so as to realize the linkage between the walking structure 13 and the slider structure 305. After the walking structure 13 returns to the initial position, the slider structure 305 enters the limiting groove 304 connected to the guide groove 303 to prevent the transverse sliding beam 4 from moving in the vertical direction. Both the guide groove 303 and the limiting groove 304 are wedge-shaped grooves or T-shaped grooves.

[0044] The top of the tower 5 is symmetrically provided with two sets of tension stabilizing structures 18 about the tower crane 7 as the axis of symmetry. The tension stabilizing structures 18 are in a tensioned state and are used to balance the eccentric force generated when the tower crane 7 is operating and the lateral tension generated when the cable is hoisting materials, so as to ensure the force balance at the top of the tower 5 and improve the stability of the tower 5.

[0045] The implementation process of this transverse large-span, large-tonnage cable crane mainly includes three stages: equipment installation, transverse adjustment, and hoisting operation. The specific steps are as follows: Equipment installation phase Based on the foundations spanning both sides of the area, two sets of load-bearing structures 1 are erected respectively, and the base platform 2 is fixedly installed on the foundations to ensure that the base platform 2 is installed flat and stable. On the foundation surface of the base platform 2, two limiting frames 301 are fixed in parallel to form a transverse channel 302. At the same time, a sinking channel 15 is reserved in the corresponding area of ​​the transverse channel 302 of the base platform 2. A bearing frame 16 and a second hydraulic pushing structure 17 are installed in the sinking channel 15, and the telescopic end of the second hydraulic pushing structure 17 is connected to the bearing frame 16. The transverse sliding beam 4 is slidably assembled on the transverse channel 16. Within the transfer channel 302, several mounting cylinders 1401 are installed on the transverse sliding beam 4. A first hydraulic pushing structure 1402 is installed within each mounting cylinder 1401. A guide cylinder 1403 is rotatably installed on the frame 1301 of the traveling structure 13. A portion of the guide cylinder 1403 is partially slidably fitted into the mounting cylinder 1401. A bearing column 1406 is installed and slidably positioned within the through groove 1404, completing the installation of the adjustment structure 14 and the traveling structure 13. The traveling structure 13 is then installed in the hollow area 1601 within the support frame 16. A first drive motor 1302 is installed on the frame 1301 of the traveling structure 13. An adjusting gear 1407 is installed on the outer wall of the guide cylinder 1403, so that the drive gear 1303 meshes with the adjusting gear 1407. Two towers 5 are installed on the transverse sliding beam 4. Several trusses 6 are installed equidistantly in the vertical direction between the two towers 5. A tower crane 7 is installed on the side wall of the transverse sliding beam 4, extending outward through the trusses 6. A loading platform 8 is installed on the top of the two towers 5, and a cable traction structure 9 is installed on the loading platform 8. Several sets of cables are installed between the cable traction structures 9 at both ends of the cross-area; locking holes are opened on the side wall of the limiting frame 301, and limiting channels are opened on the side wall of the transverse sliding beam 4. The locking rod 1101 and the sliding beam pressure anchor are prepared for use, and the assembly of the locking structure 11 is completed; two sets of traction stabilizing structures 18 are symmetrically installed on the top of the tower 5 with the tower crane 7 as the axis of symmetry. The traction stabilizing structures 18 are adjusted to the initial tension state, and then the locking rod 1101 and the sliding beam pressure anchor are installed at their preset positions to complete the installation of the entire equipment.

[0046] Lateral adjustment phase When the hoisting position of the equipment needs to be adjusted, firstly, the locking rod 1101 is pulled out from the locking hole and the limiting channel, and the sliding beam pressure anchor rod is released from the base 2, thereby releasing the locking structure 11 from locking the transverse sliding beam 4; then, the first hydraulic pushing structure 1402 in the adjustment structure 14 is activated. The telescopic end of the first hydraulic pushing structure 1402 pushes the guide cylinder 1403 to slide downward along the mounting cylinder 1401. The guide cylinder 1403 drives the bearing column 1406 to move vertically along the through groove 1404, thereby pushing the traveling structure 13 to... The bottom of the sinking channel 15 moves; simultaneously, the second hydraulic pushing structure 17 is activated, its telescopic end extends, pushing the support frame 16 upward, so that the top of the support frame 16 is embedded in the bottom of the transverse sliding beam 4, realizing the positioning connection between the two; the first drive motor 1302 is activated, the first drive motor 1302 drives the drive gear 1303 to rotate, driving the adjusting gear 1407 and the guide cylinder 1403 to rotate, so that the support column 1406 slides from the through groove 1404 into the locking groove 1405, fixing the position of the traveling structure 13; at the same time The hydraulic traction drive structure 12 is activated, and it pulls the transverse sliding beam 4 smoothly along the transverse channel 302 via a steel cable. During the transverse movement, the slider structure 305 slides horizontally along the guide groove 303, and the connecting column 1304 slides along the long groove 306, helping the transverse sliding beam 4 to remain stable. When the transverse sliding beam 4 reaches the target working position, the hydraulic traction drive structure 12 is deactivated, and the first drive motor 1302 is activated in reverse, causing the bearing column 1406 to slide back from the locking groove 1405 into the through groove 1404. The first hydraulic push structure 1402 is activated, and the traveling structure 13 is retracted from the sinking channel 15. At this time, the connecting column 1304, under the traction of the traveling structure 13, enters the limiting groove 304 from the guide groove 303 to mechanically limit the transverse sliding beam 4 and prevent it from swaying laterally. The second hydraulic push structure 17 is activated in the opposite direction to retract the telescopic end, so that the bearing frame 16 is separated from the transverse sliding beam 4. The locking rod 1101 passes through the coaxial locking hole and the limiting channel to lock and fix the transverse sliding beam 4, thus completing the transverse adjustment.

[0047] hoisting operation phase After the transverse sliding beam 4 is fixed, the cable traction structure 9 on the loading platform 8 is activated to drive the cable movement, hoisting the material onto the cable. Large-span, heavy-tonnage materials are hoisted via cable transmission. During hoisting, the tower crane 7 works in conjunction with the cable operation, adjusting the tower crane 7 to achieve precise fine-tuning of the material, ensuring accurate hoisting to the target position. During operation, the tension stabilization structure 18 adaptively adjusts its tension based on the force changes generated by the tower crane 7 operation and cable hoisting, balancing eccentric forces and lateral tension to ensure the stability of the tower 5. The truss 6 continues to function, dispersing the forces on the tower 5 and preventing deformation. After hoisting is completed, the cable traction structure 9 and tower crane 7 are shut down. If the working position needs adjustment, the steps of the transverse adjustment stage are repeated. If shutdown is required, ensure all components are in a stopped state and recheck the locking condition of the locking structure 11 to ensure equipment safety.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
