Description

Technical Field

[0001] This utility model relates to the technical field of crane lifting tower devices, and in particular to lifting towers for ultra-large tonnage gantry cranes. Background Technology

[0002] Gantry cranes are a variation of bridge cranes. In ports, they are mainly used for loading and unloading cargo and bulk materials in outdoor freight yards and material yards. Their metal structure resembles a portal frame, with two legs supporting the main beam, allowing them to travel directly on ground-level rails. The main beam can have cantilever beams extending outwards at both ends. Gantry cranes are characterized by high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards.

[0003] The lifting tower of the ultra-large tonnage gantry crane can be used for lifting large objects.

[0004] When lifting large objects, some of these objects are irregularly shaped. Simply placing the steel cable lifting jack in a fixed position for lifting is not safe, especially for objects that are larger on one side than the other. This could cause the protruding part to collide with the supporting vertical lattice column. Therefore, we have designed an ultra-large tonnage gantry crane lifting tower, which can safely and stably lift objects of various shapes. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a lifting tower for an ultra-large tonnage gantry crane, which can facilitate the safe and stable lifting of objects of various shapes.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a lifting tower frame for an ultra-large tonnage gantry crane, comprising: Two vertical lattice columns; A crossbeam, which is mounted on two vertical lattice columns; Two steel strand lifting jacks are installed together with the bottom balance beam lifting device on the two steel strand lifting jacks; The lifting jack installation mechanism includes a base plate, which is installed on the top of a crossbeam. A limiting slide plate is connected to the base plate for left and right limiting sliding. Two steel strand lifting jacks are installed on the limiting slide plate. A drive mechanism is provided on the base plate to move the limiting slide plate, so that the steel strands on the two steel strand lifting jacks can safely lift irregularly shaped objects.

[0007] Furthermore, the bottom of the steel strands on both of the aforementioned steel strand lifting jacks are jointly equipped with a balance beam lifting device.

[0008] Furthermore, the drive mechanism includes two side plates, and the two sides of the base plate are fixedly connected to the side plates. A threaded rod is rotatably connected between the two side plates, and the limiting slide is threadedly connected to the outer wall of the threaded rod. It also includes a motor, and the power output end of the motor is connected to the threaded rod.

[0009] Furthermore, a back plate is fixedly connected to the base plate, and the limiting slide plate is slidably connected to the limiting groove on the back plate.

[0010] Furthermore, the vertical lattice column includes multiple three-dimensional frames that are detachably connected to each other. Each three-dimensional frame includes two base frames, and a standard section is detachably connected between the four corners of the two base frames. Each base frame includes four slats, and the length, width, and height of the four slats are equal to those of the standard section. Adjacent base frames of two adjacent three-dimensional frames are bolted together, and a first diagonal brace is fixedly connected between the diagonally opposite corners of the two base frames. The crossbeam is installed on the three-dimensional frame at the highest point.

[0011] Furthermore, the bottom of the bottom frame is detachably equipped with multiple bottom sections, and second diagonal bracing plates are installed crosswise between the multiple bottom sections.

[0012] Compared with the prior art, the beneficial effects of this utility model include: The device can disassemble vertical lattice columns, and each disassembled three-dimensional frame is composed of the same components, which makes it easy to replace when one component is damaged. The detachable three-dimensional frame reduces the space occupied, thus facilitating storage and transportation. The device can lift objects of different shapes stably and safely using two steel strands that move left and right simultaneously. Attached Figure Description

[0019] A base plate 12 is fixedly installed on the top of the crossbeam 2. A limiting slide plate 5 is slidably connected to the base plate 12 on the left and right sides. Side plates 10 are fixedly connected to both sides of the base plate 12. A threaded rod 8 is rotatably connected between the two side plates 10. The limiting slide plate 5 is threadedly connected to the outer wall of the threaded rod 8. A motor 11 is installed on one of the side plates 10. The power output end of the motor 11 is connected to the threaded rod 8.

[0020] A back plate 7 is fixedly connected to the base plate 12, and a limiting slide plate 5 is limited and slidably connected to the limiting slide groove 9 on the back plate 7.

[0021] Two steel strand lifting jacks 6 are installed on the limit slide plate 5. The bottom of the steel strands on the two steel strand lifting jacks 6 are installed together, and a balance beam lifting device 3 is fixedly installed at the joint.

[0022] Warning lights 4 and horn alarms are installed on both sides of the top of the rear panel 7.

[0023] The controller and battery are installed on the rear panel 7. The battery powers all electrical components. The controller is electrically connected to the motor 11, warning light 4, horn alarm, and steel strand lifting jack 6 to control the operation of the device. When the steel strand lifting jack 6 is started, the warning light 4 and horn alarm activate to alert personnel and prevent accidental injury during nighttime operations.

[0024] Example 2: Based on Example 1, technical means for facilitating the storage and transportation of vertical lattice columns 1 are added.

[0025] Key reference Figure 2 This embodiment also includes a standard section 13, a first diagonal brace 14, a bottom frame 15, a bottom section 16, and a second diagonal brace 17.

[0026] The vertical lattice column 1 comprises multiple detachably connected three-dimensional frames, which are fixed together vertically by screws and nuts. Each three-dimensional frame includes two base frames 15, and detachable standard sections 13 are fixedly connected between the four corners of the two base frames 15. Each base frame 15 includes four slats, the length, width and height of which are equal to those of the standard sections 13. The two base frames 15 of adjacent three-dimensional frames are installed together by bolts.

[0027] The bottom frame 15 has multiple bottom sections 16 that can be detachably installed at the bottom, and a second diagonal brace 17 is installed between the multiple bottom sections 16.

[0028] During transportation, multiple three-dimensional frames are separated, and the four slats of the base frame 15 and the standard section 13 on each frame are identical components, facilitating replacement and maintenance should one component be damaged. Furthermore, the separable components occupy minimal space, making disassembly, storage, and transportation convenient.

[0029] The other features of Example 2 are the same as those of Example 1.

[0030] In the specific implementation, the tower height of the vertical lattice column 1 is first determined, different numbers of three-dimensional frames are selected, and then the standard section 13, the bottom frame 15, and the first diagonal brace plate 14 are assembled and installed into a three-dimensional frame. When a component is damaged, it is easy to replace because they are all the same components.

[0032] Then the crossbeam 2 is installed on the two vertical lattice columns 1 to form a gantry structure.

[0033] When an object needs to be lifted, the positions of the two steel cable lifting jacks 6 are adjusted according to the shape of the object. If the left side of the object is too large, the drive motor 11 moves the two steel cable lifting jacks 6 to the right, allowing the lifted object to be safely placed between the two vertical lattice columns 1. If the right side of the object is too large, the drive motor 11 moves the two steel cable lifting jacks 6 to the left, ensuring the lifted object is safely placed between the two vertical lattice columns 1.
