Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ship loader technology, specifically relating to a ship loader pitch and slewing device. Background Technology
[0002] Ship loaders are large bulk material loading machines used in dock loading. They are one of the important pieces of equipment for loading and unloading bulk cargo at large port bulk cargo terminals, and can continuously load various bulk materials from barges onto ships.
[0003] Existing ship loader structures mostly consist of a movable support platform with a support frame mounted on it. A cantilever is hinged to one side of the bottom of the support frame, and the other end of the cantilever is connected to a wire rope. The wire rope is wound around a pulley at the top of the support frame and then connected to a winch. A counterweight is placed on the side of the support frame away from the cantilever. The winch is used to tilt the cantilever, and the rotation of the support frame is used to adjust the cantilever's direction. Conveying equipment is installed on the cantilever to transport materials. Because the support frame needs to support the entire tilting structure and complete the rotation, the size and strength requirements of its bearings are high, and the power demand is large. At the same time, the bearings are prone to damage due to the high pressure. Summary of the Invention
[0004] This invention addresses the problem that existing ship loader cantilever frames require high-quality bearings with high dimensions and strength, and also have significant power demands, leading to easy damage due to high bearing pressure. It provides a ship loader pitching and slewing device that uses a hinged cantilever frame on the support platform to rotate the hinged seat during swaying, eliminating the need to rotate the support frame. A hinged gooseneck frame is used to mount the first pulley, ensuring the wire rope does not twist or knot during cantilever swaying. This device effectively reduces bearing stress, lowers bearing strength requirements, reduces power consumption, and lowers costs while ensuring smooth pitching and swaying of the cantilever frame.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A ship loader pitch and slewing device includes a support platform with a hinge seat rotatably mounted on the support platform. A cantilever frame is hinged to the hinge seat. A support frame is fixedly mounted on the support platform. A steering device is provided on one side of the top of the support frame. The steering device includes a mounting base and a gooseneck frame. A first pulley is provided on the gooseneck frame. The gooseneck frame is hinged to the mounting base, and the mounting base is fixedly connected to the support frame. A winding device is provided on the support frame. A steel wire rope is wound on the winding device, and the other end of the steel wire rope passes over the first pulley and connects to the end of the cantilever frame away from the hinge seat. When the cantilever frame rotates around the hinge seat, the gooseneck frame swings at a certain angle, allowing the cantilever frame to swing smoothly.
[0007] Preferably, an inclined triangular bracket is fixedly provided at the upper end of the support frame, and the top of the triangular bracket extends out of one side of the support frame and is fixedly connected to the mounting base.
[0008] Preferably, the triangular bracket is provided with a second pulley, which is located below the mounting base, and the second pulley prevents the wire rope from interfering with the triangular bracket.
[0009] The first pulley is set to two, so that when the wire rope lifts one end of the cantilever, it is under multiple stresses, thus avoiding excessive stress on the wire rope.
[0010] Preferably, a connecting column is hinged at one end of the cantilever frame, and a third pulley is provided at the upper end of the connecting column. One end of the wire rope is connected to a winding device, and the other end is sequentially wound around a second pulley, a first pulley located above, a third pulley, and a first pulley located below before being fixedly connected to the connecting column.
[0011] Preferably, the mounting base has a through hole at the end away from the support frame, and the goose head frame is provided with a hinge shaft. The hinge shaft is located in the through hole and its two ends extend out of the through hole and are fixedly connected to the goose head frame. The goose head frame is hinged and installed by the cooperation between the hinge shaft and the through hole.
[0012] Preferably, the winding device is a winch fixedly mounted on a support frame.
[0013] Preferably, the support platform is equipped with rollers at its lower part to facilitate the movement of the ship loader.
[0014] Preferably, the hinge is rotatably connected to the support platform via a bearing.
[0015] Preferably, the support platform is further provided with a power device for driving the hinge seat to rotate.
[0016] The beneficial effects of this utility model through the above technical solution are as follows:
[0017] This utility model involves rotating and installing a hinge seat on a support platform, with one end of the cantilever frame hinged to the hinge seat. Without affecting the pitching motion of the cantilever frame, when the cantilever frame swings at a certain angle, the support frame does not need to rotate accordingly. Compared with the original bearing installed at the lower part of the support frame, the bearing installed at the lower end of the hinge seat bears less pressure, effectively extending the service life of the bearing, while also having lower requirements for the size and strength of the bearing.
[0018] By reducing the rotation of the support frame, the power input required to drive the cantilever to swing is reduced, thus reducing energy consumption and saving costs.
[0019] By setting up a steering device, the first pulley swings at a corresponding angle as the cantilever swings, ensuring the stability of the cantilever swing and ensuring the smooth operation of the ship loader. Attached Figure Description

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0025] like Figures 1-3 As shown, this embodiment provides a pitch and slewing device for a ship loader, characterized in that it includes a support platform 1, on which a hinge seat 2 is rotatably mounted, and a cantilever frame 3 is hingedly mounted on the hinge seat 2. Specifically, the hinge seat 2 is rotatably connected to the support platform 1 through a bearing. Compared with the existing ship loader where the bearing is connected between the support frame 4 and the support platform 1, this reduces the pressure of the support frame 4 on the bearing, extends the service life of the bearing, reduces the size and strength requirements of the bearing, and improves the applicability of the device.
[0026] The support platform 1 is also equipped with a power device (not shown in the figure) for driving the hinge seat to rotate. The power device is a motor or a motor reducer. The output end of the power device is fixedly connected to a first gear. A second gear is fixedly sleeved on the hinge seat 2. The first gear meshes with the second gear.
[0027] A support frame 4 is fixedly installed on the support platform 1. A steering device is provided on one side of the top of the support frame 4. The steering device includes a mounting base 5 and a gooseneck frame 6. The gooseneck frame 6 is provided with two first pulleys 7 arranged vertically. The gooseneck frame 6 is hinged to the mounting base 5. The mounting base 5 is fixedly connected to the support frame 4. When the cantilever frame 3 swings, since the gooseneck frame 6 is hinged to the mounting base 5, the gooseneck frame 6 swings at a corresponding angle, effectively preventing the wire rope 9 from detaching from the first pulley 7.
[0028] The support frame 4 is equipped with a winding device 8, on which a steel wire rope 9 is wound. The other end of the steel wire rope 9 passes over the first pulley 7 and is connected to the end of the cantilever frame 3 away from the hinge seat 2. The winding device 8 is a winch fixedly installed on the support frame 4. The cantilever frame 3 can be tilted by winding or releasing the steel wire rope 9 through the winding device 8.
[0029] An inclined triangular bracket 10 is fixedly installed at the upper end of the support frame 4. The top of the triangular bracket 10 extends out of one side of the support frame 4 and is fixedly connected to the mounting base 5. The triangular bracket 10 includes two support rods, and the two support rods and the top of the support frame 4 form a triangular frame structure for supporting the mounting base 5 and the goose head frame 6.
[0030] The triangular bracket 10 is equipped with a second pulley 11, which is located below the mounting base 5. One end of the cantilever frame 3 is hinged to a connecting column 12, and the upper end of the connecting column 12 is equipped with a third pulley 13. One end of the wire rope 9 is connected to the winding device 8, and the other end is wound sequentially around the second pulley 11, the upper first pulley 7, the third pulley 13, and the lower first pulley 7 before being fixedly connected to the connecting column 12. This winding of the wire rope 9 serves two purposes: firstly, the second pulley 11 allows the wire rope 9 to avoid interference with the triangular bracket 10; secondly, between the gooseneck frame 6 and the connecting column 12, at least three wire ropes bear the tension, ensuring the tension of the wire rope 9 on the cantilever frame 3 and preventing a single wire rope 9 from breaking due to excessive stress.
[0031] It should be noted that the steering device is vertically aligned with the hinge 2 to ensure that the steering angle is consistent when the cantilever 3 swings.
[0032] The mounting base 5 has a through hole 14 at one end away from the support frame 4. The goose head frame 6 is provided with a hinge shaft 15. The hinge shaft 15 is located in the through hole 14 and its two ends extend out of the through hole 14 and are fixedly connected to the goose head frame 6. The through hole 14 is rotatably connected to the hinge shaft 15 through a bearing. Thus, the through hole 14 and the hinge shaft 15 cooperate to realize the hinged installation of the goose head frame 6.
[0033] The support platform 1 is equipped with rollers 16 at its lower part to facilitate the movement of the ship loader.
[0034] When in use, when the cantilever 3 needs to be tilted, start the winch to wind up or release the wire rope 9 to achieve the tilting action of the cantilever 3.
[0035] When the cantilever 3 needs to swing at a certain angle, the power unit drives the hinge 2 to rotate at a certain angle, causing the cantilever 3 to swing at the corresponding angle, and causing the gooseneck frame 6 to swing at the corresponding angle, thus realizing the smooth swing of the cantilever 3 without the support frame rotating accordingly.
[0036] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
