Description

Technical Field

[0001] The utility model relates to a vessel maintenance device for waterway management, in particular to a ten-meter single-vessel lifting device. Background Art

[0002] In the process of waterway management, traditional single-arm crane equipment is often used, especially when lifting a single ten-meter vessel. However, this type of equipment has exposed some significant defects in actual use. First, due to the limitations of the single-arm design, the lifting process is easily affected by the displacement of the ship's center of gravity and external environmental factors (such as wind), resulting in poor stability and increasing operational risks. Secondly, the lifting capacity of a single-arm crane is limited. Especially when faced with the increased weight of the anchor chain due to siltation, the equipment often cannot provide sufficient lifting force, making it difficult to successfully complete the task. In addition, the single-arm design lacks flexibility in complex construction environments. When encountering a large number of obstacles or requiring precise positioning, single-arm crane equipment cannot effectively cope with the situation, reducing work efficiency and increasing operational difficulty. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a ten-meter single ship lifting device, which can not only solve the problem that the boom cannot provide sufficient lifting force and has low stability when lifting a ten-meter single ship, but also solve the problem of poor flexibility.

[0004] In order to solve the above technical problems, the ten-meter single-ship lifting device of the utility model includes a No. 1 lifting body and a No. 2 lifting body located in the single-ship berthing area. The No. 1 lifting body is hung with a No. 1 lifting hoist, and the No. 2 lifting body is hung with a No. 2 lifting hoist. The No. 1 lifting body and the No. 2 lifting body are arranged relative to each other and can enable the No. 1 lifting hoist to be hoisted at the bow of the single ship, and the No. 2 lifting hoist to be hoisted at the stern of the single ship at the same time; through the coordinated work of the No. 1 lifting hoist and the No. 2 lifting hoist, the single ship can be lifted to realize the maintenance operation of the single ship.

[0005] The No. 1 lifting body and the No. 2 lifting body both include a lifting arm, a supporting base plate, a supporting rod connected between the lifting arm and the supporting base plate, and a fixing plate fixedly installed between the lifting arm and the supporting rod.

[0006] The front end of each boom is provided with a suspension component.

[0007] A supporting oblique beam is provided between the boom and the support rod; one end of the supporting oblique beam is fixed to the front of the boom, while the other end is fixed to the lower part of the support rod, forming a triangular structure to provide additional support for the boom.

[0008] The included angle between the boom and the support rod is in the range of 90°-120°.

[0009] A rotating support structure for supporting the support rod is installed on the support base plate, and the support rod is installed on the support base plate through the rotating support structure.

[0010] The rotating support structure includes a support sleeve fixedly mounted on the support base plate and a support shaft arranged in the support sleeve, an upper deep groove ball bearing and a lower deep groove ball bearing supported in the support sleeve are installed on the support shaft, and a thrust ball bearing located below the lower deep groove ball bearing is also arranged between the support sleeve and the support shaft, the support shaft extends out from above the support sleeve and is fixedly connected to the support rod 8, and the top of the upper deep groove ball bearing is sealed with a cover plate for positioning the upper deep groove ball bearing.

[0011] The support base plate is provided with a groove, into which a tapered roller bearing is embedded that is fitted with the support shaft 17 .

[0012] The No. 1 lifting hoist and the No. 2 lifting hoist are both electric hoists.

[0013] The support rod is fixedly mounted on the support base plate and at least three reinforcing rib plates are arranged on the support base plate and are distributed around the edges of the support rod.

[0014] The utility model has the advantages:

[0015] (1) By designing the relative arrangement of the No. 1 and No. 2 lifting bodies, which are located at the bow and stern respectively, higher stability is ensured during the lifting process, and the operational risks caused by the shift of the center of gravity of the ship are reduced; the coordinated work of the two lifting hoists enables the equipment to provide stronger lifting capacity, especially when facing the situation where the weight of the anchor chain increases due to siltation, ensuring the smooth completion of the lifting task.

[0016] (2) The entire device has a reasonable structural design. The supporting inclined beams set between the boom and the support rod form a triangular structure, which further enhances the support force and stability of the boom, thereby improving the flexibility and adaptability of the equipment in complex construction environments;

[0017] (3) The rotating support structure installed on the support base allows the boom to rotate flexibly, which enhances the accuracy of operation and makes it easier to deal with obstacles and special layouts.

[0018] (4) By designing the specific structure of the rotary support structure, on the one hand, the upper deep groove ball bearing and the lower deep groove ball bearing placed between the support shaft and the support sleeve are used for rotary support, and on the other hand, the thrust ball bearing located below the lower deep groove ball bearing is placed between the support sleeve and the support shaft, thereby achieving radial and axial support at the same time. The support is reliable, ensuring the reliability of use and extending the service life. On the other hand, the support sleeve is directly fixed to the support base plate, and the upper deep groove ball bearing is packaged and positioned by the cover plate, which makes it easy to install and disassemble, easy to maintain and replace, and has strong replaceability.

[0019] (5) By providing a groove on the support base plate and embedding a tapered roller bearing in the groove to be mounted in conjunction with the support shaft, the axial support and centering function of the tapered roller bearing is cleverly utilized, thereby further improving the stability and reliability of use.

[0024] The ten-meter single-ship lifting device of the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods. Example 1

[0025] like Figure 1 As shown, the 10-meter single ship lifting device of this embodiment includes a No. 1 lifting body 1 and a No. 2 lifting body 2 located in the single ship berthing area. The No. 1 lifting body 1 is located at the bow of the single ship, and the No. 2 lifting body 2 is located at the stern of the single ship. Figure 2It can be seen that the said No. 1 lifting body 1 and No. 2 lifting body 2 both include a boom 6, a supporting base plate 7, a supporting rod 8, a fixing plate 9 and a rotating support structure 12 installed on the supporting base plate 7 for supporting the supporting rod 8. When installed, the supporting rod 8 is installed on the supporting base plate 7 through the rotating support structure 12, thereby allowing the boom to rotate 360 degrees to achieve the purpose of flexible use; the fixing plate 9 is fixedly installed between the boom 6 and the supporting rod 8, and the angle between the boom 6 and the supporting rod 8 is in the range of 90 °-120°, the front end of each lifting arm 6 is provided with a suspension component 10, the No. 1 lifting body 1 and the No. 2 lifting body 2 are respectively hung with the No. 1 lifting hoist 3 and the No. 2 lifting hoist 4 through their own suspension components, the No. 1 lifting body 1 and the No. 2 lifting body 2 are arranged relative to each other and can enable the No. 1 lifting hoist 3 to be hoisted at the bow of the single ship, and the No. 2 lifting hoist to be hoisted at the stern of the single ship; through the coordinated work of the No. 1 lifting hoist 3 and the No. 2 lifting hoist 4, the single ship can be lifted to realize the maintenance operation of the single ship 5.

[0026] Furthermore, a supporting inclined beam 11 can be provided between the boom 6 and the support rod 8, with one end of the supporting inclined beam 11 fixed to the front of the boom 6 and the other end fixed to the lower part of the support rod 8, forming a triangular structure to provide additional support for the boom 6. At the same time, for the convenience of operation, both the No. 1 lifting hoist 3 and the No. 2 lifting hoist 4 can be electric hoists.

[0027] Furthermore, if Figure 3 As shown, the rotating support structure 12 includes a support sleeve 16 fixedly mounted on the support base plate and a support shaft 17 arranged in the support sleeve. The support shaft 17 is equipped with an upper deep groove ball bearing 14 and a lower deep groove ball bearing 13 supported in the support sleeve. A thrust ball bearing 15 located below the lower deep groove ball bearing 13 is also arranged between the support sleeve 16 and the support shaft 17. The support shaft 17 extends above the support sleeve and is fixedly connected to the support rod 8. The top of the upper deep groove ball bearing 14 is sealed with a cover plate 18 for positioning the upper deep groove ball bearing 14. The specific installation structure is as shown in FIG. Figure 4As shown, the support shaft 17 is processed with an upper limit step and a lower limit step, the upper part of the support sleeve 16 is processed with an upper mounting groove that cooperates with the upper limit step, and the lower part of the support sleeve 16 is processed with a lower mounting groove that cooperates with the lower limit step. The lower mounting groove is a two-step groove, and the bottom of the support sleeve 16 has a flange for installation with the support base plate. During installation, the lower deep groove ball bearing 13 is installed on the support shaft and limited by the lower limit step, and then the support shaft is installed from the bottom of the support sleeve 16. After installation, the lower deep groove ball bearing 13 is limited at the first step groove of the support sleeve, and then the thrust ball bearing 15 is also installed on the support shaft and is located below the lower deep groove ball bearing 13 and is located at the second step groove of the support sleeve. During installation, attention should be paid to the fixed installation of the moving ring of the thrust ball bearing 15. Installed on the support shaft, the static ring of the thrust ball bearing 15 is fixedly installed in the second-level stepped groove of the support sleeve to maintain reliable rotational support, and then the upper deep groove ball bearing 14 is installed at the upper limit step of the support shaft, and positioned in the upper mounting groove of the support sleeve. It is best to put the cover plate on the outside of the support shaft and press it on the top surface of the outer ring of the upper deep groove ball bearing 14. At this time, the support sleeve is fixedly installed and installed on the support base plate 7 by fasteners, and the cover plate is fixedly connected to the top surface of the support sleeve by fasteners. In addition, in order to facilitate the connection between the support shaft and the support rod, a boss can be cut on the upper part of the support shaft, and a positioning hole matching the boss is provided at the bottom of the support rod. After the positioning hole of the support rod is positioned and installed on the boss of the support shaft, the two are fixedly connected by installing fasteners around the support rod.

[0028] Furthermore, in order to further improve the flexibility of rotation and the stability and reliability of use, a groove can be processed on the support base plate 7, and a tapered roller bearing 19 is embedded in the groove to be installed in conjunction with the support shaft 17. At this time, a connecting section can be processed at the bottom of the support shaft. Since the tapered roller bearing is a separable rolling bearing, the inner ring and outer ring of the tapered roller bearing can be installed separately during installation, that is, the outer ring of the tapered roller bearing is fixedly installed in the groove, and the inner ring of the tapered roller bearing can be fixedly installed on the connecting section. The installation is very convenient. After installation, the tapered roller bearing can withstand the combined load of radial load and unidirectional load, thereby realizing the functions of unidirectional (axial) and radial load support and centering, further improving the load-bearing capacity, and achieving outstanding use effect. Example 2

[0029] The difference between this embodiment and embodiment 1 is that this embodiment does not include a rotating support structure. Specifically, in this embodiment, the support rod is directly mounted on the support base plate 7, and at least three reinforcing ribs are arranged on the support base plate and are distributed around the edges of the support rod. Although this structural design cannot perform a rotating operation, such a simple structure can reduce subsequent maintenance work.
