Description

TECHNICAL FIELD

[0001] The present application relates to the field of shore cranes, in particular to the field of shore crane anchoring devices. BACKGROUND

[0002] A shore crane, also known as a shore bridge, is usually deployed in the coastal area. In order to ensure the stability and safety of the shore crane equipment, an anchoring device with anti-sliding function is generally provided in the direction of travel of the trolley of the shore crane.

[0003] The anchoring device of the shore crane is usually installed below the lower cross beam or the trolley balance beam, and uses a vertical insertion type anchoring plate. Since the positions of the pre-buried pits of the anchoring wharf and the pre-buried pits of the wind-resistant cable are relatively fixed, when there is an error in the manufacture or installation of the anchoring plate of the shore crane, it is difficult to ensure that both the wind-resistant cable and the anchoring plate of the shore crane can be accurately inserted into the pre-buried pit, and when necessary, the anchoring plate can only be partially trimmed to adapt to the size requirements. On the other hand, in order to ensure the smooth vertical insertion of the anchoring plate, the size of the anchoring plate is usually slightly smaller than that of the anchoring pit, and when there is a tendency for the trolley to move, the anchoring plate cannot be stressed in the first time, and the wind-resistant cable that has been tensioned and can only bear vertical force may bear horizontal force and be damaged. SUMMARY

[0004] An object of the present application is to provide a shore crane anchoring structure that can improve the adaptability of the anchoring plate and the anchoring pit.

[0005] To achieve the above-mentioned object, the shore crane anchoring structure comprises an anchoring support, a first pin shaft assembly and a second pin shaft assembly. The anchoring support is arranged at the bottom of the shore crane and comprises a containing space. The first pin shaft assembly is arranged in the containing space and comprises a first pin shaft and a first shaft sleeve, the first shaft sleeve being rotatably sleeved on the first pin shaft. The second pin shaft assembly is arranged below the containing space and comprises a second pin shaft and a second shaft sleeve, the axial direction of the second pin shaft being parallel to the first pin shaft, the second shaft sleeve being fixedly connected with the first shaft sleeve through a connecting frame, the second pin shaft being connected with the anchoring plate, and the second shaft sleeve being threadedly connected with the second pin shaft to adjust the relative position of the anchoring plate and the second shaft sleeve by means of the threaded connection.

[0006] In one or more embodiments, the axial direction of the first pin shaft is parallel to the length direction of the anchoring pit.

[0007] In one or more embodiments, a first handle is arranged on the second shaft sleeve and / or the connecting frame.

[0008] In one or more embodiments, the anchoring plate is provided with a pair of connecting plates, and the two ends of the second pin shaft are detachably connected with the connecting plates, respectively.

[0009] In one or more embodiments, the outer surface of the second pin shaft includes an exposed portion not covered by the second shaft sleeve, the exposed portion being provided with a pin hole for inserting a second handle.

[0010] In one or more embodiments, the second handle is connected to the anchoring bracket through a chain.

[0011] In one or more embodiments, the anchoring bracket is arranged on a cart traveling mechanism.

[0012] In one or more embodiments, the anchoring pit has any one of a rectangular, circular, or elliptical cross section.

[0013] Another object of the present application is to provide a shore crane comprising the shore crane anchoring structure described above.

[0014] The shore crane anchoring structure described above changes the gap between the left and right sides of the pin shaft and the anchoring pit through the threaded connection between the second shaft sleeve and the second pin shaft, thereby adjusting the matching degree of the anchoring plate and the anchoring pit; at the same time, when the shore crane does not need to be anchored, the second pin shaft assembly is rotated around the first pin shaft to the side away from the anchoring pit, which is convenient to store and does not interfere with other components.

[0041] The present application will be further described below in connection with specific embodiments and with reference to the attached drawings, in which more details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, that the present application can be practiced in a variety of ways beyond those specifically described herein without departing from the spirit and scope of the present application. Accordingly, the specific embodiments described herein should not be construed as limiting the scope of the present application.

[0042] It should be noted that these and other subsequent figures are merely examples and are not drawn to scale, and should not be used to limit the scope of the protection actually claimed for the present application.

[0043] The shore-based bridge includes a door frame structure, a girder structure, a lifting mechanism, a trolley traveling mechanism, and a large trolley traveling mechanism. The shore-based bridge is usually deployed in an area along the coast, which is directly threatened by typhoons, and therefore the shore-based bridge is usually equipped with an anchoring device with an anti-sliding function.

[0044] At present, the anchoring device of the shore-based bridge is mostly an insertion plate or an insertion pin, which is used to fix the shore-based bridge by cooperating with the anchoring pit pre-buried on the wharf. The anchoring pit is arranged around the parking position of the shore-based bridge, and the number is determined according to the scale and working conditions of the shore-based bridge. Each anchoring pit cooperates with each group of anchoring devices on the shore-based bridge, so that the insertion plate or the insertion pin is inserted into the anchoring pit to achieve fixation.

[0045] In their paper "Design of Automatic Anchoring Device for Gantry Crane Trolley" (Port Loading and Unloading, 2011, (04): 29-30), Luo Shidong et al. proposed an automatic anchoring device, including an anchoring seat, an anchoring pin, an anchoring self-locking plate, a spring, an anchoring lifting mechanism, and an anchoring lifting linkage structure. The anchoring seat and anchoring pin, like other anchoring methods, serve to fix the trolley. The anchoring lifting mechanism lifts the anchoring pin during the trolley's entry into and exit from the anchoring position. The anchoring linkage structure transmits the force and motion of the anchoring lifting mechanism to the anchoring pin. The anchoring self-locking protection device ensures that the anchoring pin is in a raised state when the trolley is not in an anchoring position, preventing damage caused by the trolley colliding with the anchoring mechanism due to strong winds or limit switch failure. This automatic anchoring device achieves automatic anchoring and eliminates the problem of anchor jamming, but it cannot solve the problem of how to accurately match the insert plate and the anchoring pit.

[0046] Chinese patent CN2866437Y discloses an adjustable anchoring device. Symmetrically arranged on both sides of the insert plate are threaded pairs consisting of screw sleeves and bolts on the anchoring seats. The screw sleeves are welded to the anchoring seats. Rotation adjusts the gap between the two bolts to accommodate the width requirements of the insert plate. Utilizing the engagement characteristics of the threaded pairs, the gap between the insert plate and the anchoring seats is eliminated, effectively limiting the horizontal swaying of mobile lifting equipment on rails during non-operation periods caused by the gap between the insert plate and the anchoring seats. However, this adjustment only addresses the gap between the insert plate and the anchoring seats and cannot solve the problem of the fit between the insert plate and the anchoring pit.

[0047] To address the above problems, this disclosure proposes a shore bridge anchorage structure, such as... Figure 1 As shown in Figure 3, it includes an anchor bracket 5, a first pin assembly 10, and a second pin assembly 20.

[0048] Anchoring bracket 5 is installed at the bottom of the quay crane, or on the trolley traveling mechanism 4, and has a accommodating space 50, such as through... Figure 1 The pair of vertical plates 51 and 51' shown are defined and formed.

[0049] The first pin assembly 10 is disposed within the accommodating space 50 and includes a first pin 11 and a first bushing 12, wherein the first bushing 12 is rotatably fitted onto the first pin 11.

[0050] The second pin assembly 20 is disposed below the accommodating space 50 and between the accommodating space 50 and the anchoring pit 2. It includes a second pin 21 and a second bushing 22. The axial direction of the second pin 21 is parallel to that of the first pin 11.

[0051] The second bushing 22 is fixedly connected to the first bushing 12 via a connecting bracket 30. For example, in... Figure 1 In the embodiment shown, the connecting frame 30 is in a constricted shape, with its wide end connected to the first bushing 12 and its narrow end connected to the second bushing 22.

[0052] Preferably, the connecting frame 30, the second shaft sleeve 22 and the first shaft sleeve 12 are welded with the same material to prevent cracking in the later stage and finally ensure the safety of the whole machine.

[0053] Since the three are fixedly connected, when the first shaft sleeve 12 rotates relative to the first pin shaft 11, the second shaft sleeve assembly as a whole will rotate.

[0054] The second pin shaft 21 is connected with the anchoring plate 3. Specifically, the anchoring plate 3 is provided with a pair of connecting plates 31, and the two ends of the second pin shaft 21 are respectively matched with the shaft holes on the connecting plates 31. The second pin shaft 21 and the connecting plates 31 are detachably connected.

[0055] The second shaft sleeve 22 is threadedly connected with the second pin shaft 21. The thread structure between the second shaft sleeve 22 and the second pin shaft 21 can adjust the relative position of the anchoring plate 3 and the second shaft sleeve 22. As shown in Figure 1 , if there is an error in the matching size of the second pin shaft 21 and the embedded pit 2, the relative position of the second pin shaft 21 between the direction L and the second shaft sleeve 22 is changed by rotating the second pin shaft 21 through the thread, and then the gap between the anchoring plate 3 and the anchoring pit 2 is adjusted, so as to finally realize the precise butt joint matching of the anchoring plate 3 and the anchoring pit 2, ensure the distance between the pin shaft and the anchoring pit, and prevent the wind cable from being subjected to excessive horizontal force.

[0056] In the embodiment shown in Figure 1 , the direction L is the length direction of the anchoring pit 2, and the axial direction of the first pin shaft 11 and the second pin shaft 12 is parallel to the length direction of the anchoring pit 2.

[0057] If the distance error is very large, the second pin shaft 21 can also be screwed out of the connecting plate 31 of the anchoring plate 3 for re-production and connection.

[0058] In an embodiment, the inner circumferential surface of the second shaft sleeve 22 is provided with an internal thread, and the middle region of the outer circumferential surface of the second pin shaft 21 is provided with an external thread, and the two side regions are not covered by the second shaft sleeve 22, which are bare parts 210. The bare part is provided with a pin hole 211 for inserting a second handle 62, as shown in Figure 4 and Figure 5 . After the second handle 62 is inserted into the pin hole, it acts as a rotating handle to rotate the second pin shaft 21, so that the second pin shaft 21 rotates relative to the second shaft sleeve 22, realizes the length adjustment of the pin shaft left and right, and then drives the anchoring plate 3 to move relative to the anchoring pit 2. The second handle 62 can be fixed on the anchoring support by a chain when not in use.

[0059] This structure does not need to specially modify the existing embedded parts and embedded pits of the wharf.

[0060] Since the second shaft sleeve 22, the connecting frame 30 and the first shaft sleeve 12 are fixedly connected, when the shore crane is working, i.e. in the anchoring non-working state, the second pin shaft assembly 20 is rotated to the upper side of the first pin shaft assembly 10, as shown in the figure, without interference with other components. The first handle 61 is arranged on the second shaft sleeve and / or the connecting frame, facilitating the overturning of the second pin shaft assembly. When anchoring is needed, the second pin shaft assembly is rotated around the first pin shaft through the connecting bracket, manually lowered between the anchoring pit and the accommodation space, and connected with the anchoring plate, and the relative position between the anchoring plate and the anchoring pit is adjusted by using the threaded pair. Figures 3A-3B

[0061] The connection of the second pin shaft and the connecting frame with the anchoring bracket through the first pin shaft assembly cancels the traditional vertical anchoring plate and the matching long handle for operation, greatly reduces the length and width required for installation of the anchoring device, is beneficial to the arrangement of the anchoring device when the number of wheels of the trolley is too large or the wheelbase is too large, avoids the interference of the long handle with the trolley guard rail, the trolley driving device, the electrical operation station, the cargo handling room and the platform and other objects, and also eliminates the need for two people to operate the anchoring.
