Abstract
Description
Technical Field
[0001] This utility model relates to the field of crane equipment technology, and in particular to a gantry anchoring device with a flexible connection. Background Technology
[0002] A gantry crane is a bridge-type crane whose bridge frame is supported on ground rails by outriggers on both sides. It is mainly used for loading and unloading of goods and bulk materials in outdoor freight yards and material yards.
[0003] When using gantry cranes outdoors, anchoring devices are required to secure their end beams to prevent displacement and tipping due to external forces when the crane is not in operation. Traditionally, gantry cranes use welding to attach the anchoring devices to the end beams. However, the high temperatures during welding often cause deformation of the end beams, affecting the crane's quality. Furthermore, the anchoring devices are frequently welded to the web of the end beam, leading to uneven stress on the beam and increased stress on the web, resulting in low safety performance. Welded connections also prevent disassembly of the anchoring devices, making maintenance inconvenient and potentially affecting the crane's movement and transportation. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a gantry anchoring device with a flexible connection, which makes the end beam more uniformly stressed, has high safety performance, and can also be disassembled, making it convenient for maintenance and repair of the anchoring device.
[0005] This utility model provides a gantry anchoring device with a flexible connection, including an anchoring bracket, an upper anchoring plate, a lower anchoring plate, a fixing cylinder, and an anchoring shaft.
[0006] The upper anchor plate and the lower anchor plate are arranged parallel to each other on one side of the anchor bracket. The upper anchor plate, the lower anchor plate and the anchor bracket form a C-shaped placement groove for the end beam to be inserted. Both the upper anchor plate and the lower anchor plate are provided with bolt groups for fixing the end beam.
[0007] The fixing cylinder is fixedly installed on the other side of the anchoring bracket, and the anchoring shaft passes through the fixing cylinder. The anchoring shaft can be moved downward and inserted into the anchoring groove on the foundation for fixation.
[0008] Furthermore, the cross-section of the anchoring shaft is rectangular, and two sets of support plates are symmetrically arranged inside the fixing cylinder. The gap between the two sets of support plates is greater than the width of the anchoring shaft and less than the length of the anchoring shaft.
[0009] Furthermore, the groove of the anchoring groove is rectangular, and the anchoring shaft is fitted with the groove.
[0010] Furthermore, limit plates are provided on both outer walls along the length of the anchoring shaft.
[0011] Furthermore, a lifting handle is provided at the top of the anchoring shaft.
[0012] Furthermore, a positioning block is fixedly provided at the end of both the upper anchor plate and the lower anchor plate away from the anchor bracket.
[0013] Furthermore, shear blocks are provided on both sides of the upper anchor plate and the lower anchor plate symmetrical about the positioning block.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] (1) The upper anchor plate, lower anchor plate and anchor bracket of this utility model are C-shaped. The end beam can be inserted into the C-shaped placement groove. Then the upper and lower sides of the end beam are fixed by the bolt group on the upper and lower anchor plates. Then the anchor shaft is inserted into the anchor groove on the foundation and fixed to complete the anchoring of the end beam. Compared with the traditional anchoring method of welding to the web of the end beam, this application makes the upper and lower sides of the end beam bear force, making the end beam bear force more evenly, avoiding excessive local force and deformation of the end beam, making the mechanical structure more reasonable and improving the stability of the anchoring device.
[0016] (2) Both the upper and lower anchor plates of this utility model are fixed to the end beam by bolt groups. By rotating the bolts, the anchoring device can be easily removed from the end beam for maintenance and repair.

It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0027] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] Please refer to Figures 1-3 The present invention provides a gantry anchoring device with a flexible connection. In the field of cranes, gantry cranes travel along the track to carry out lifting work. When fixation is required, the end beam 8 of the gantry crane is anchored by the anchoring device of this application to avoid external forces from pushing the gantry crane and causing accidents.
[0029] This application includes an anchor bracket 1, an upper anchor plate 2, a lower anchor plate 3, a fixing cylinder 4, and an anchor shaft 5.
[0030] The upper anchor plate 2 and the lower anchor plate 3 are arranged parallel to each other on one side of the anchor bracket 1. The upper anchor plate 2, the lower anchor plate 3 and the anchor bracket 1 form a C-shaped placement groove for the end beam 8 to be inserted. Both the upper anchor plate 2 and the lower anchor plate 3 are provided with bolt groups 6 for fixing the end beam 8. Specifically, the anchor bracket 1 has a cuboid structure. The upper anchor plate 2 and the lower anchor plate 3 have the same structure and are both fixedly connected to the anchor bracket 1.
[0031] The fixing cylinder 4 is fixedly installed on the other side of the anchoring bracket 1, and the anchoring shaft 5 passes through the fixing cylinder 4. The anchoring shaft 5 can move downward and be inserted into the anchoring groove 7 on the foundation for fixation. Specifically, multiple anchoring grooves 7 are provided on the foundation along the path of the track. The anchoring grooves 7 are structurally matched with the anchoring shaft 5, and the anchoring shaft 5 can be inserted into the anchoring groove 7 for stable fixation.
[0032] In this embodiment, the upper anchor plate 2, the lower anchor plate 3, and the anchor bracket 1 form a C-shape. The end beam 8 can be inserted into the C-shaped placement groove. The upper anchor plate 2 and the lower anchor plate 3 firmly hold the end beam 8 in place. Then, the bolt group 6 on the upper anchor plate 2 and the lower anchor plate 3 fixes the upper and lower sides of the end beam 8. Compared with the traditional anchoring method of welding to the web of the end beam, this application allows the upper and lower sides of the end beam 8 to be stressed, making the stress on the end beam 8 more uniform, avoiding excessive local stress and deformation of the end beam 8, making the mechanical structure more reasonable, and improving the stability of the anchoring device. When anchoring is required, the anchoring shaft 5 is inserted into the anchoring groove 7 on the foundation and fixed to complete the anchoring of the end beam 8. Moreover, the end beam 8 is connected to the upper anchor plate 2 and the lower anchor plate 3 by bolts, which makes it convenient to disassemble the anchoring device for maintenance and repair. When the gantry crane passes through narrow spaces, it is convenient to disassemble the anchoring device to avoid the anchoring device affecting the normal operation and transportation of the gantry crane.
[0033] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, the anchoring shaft 5 has a rectangular cross-section. Two sets of support plates 41 are symmetrically arranged inside the fixing cylinder 4. The gap between the two sets of support plates 41 is greater than the width of the anchoring shaft 5 and less than its length. Specifically, the fixing cylinder 4 is a cuboid structure with a hollow interior. The anchoring shaft 5 is movably inserted inside the fixing cylinder 4. The anchoring shaft 5 is also a cuboid structure with a rectangular cross-section. The gap between the two sets of support plates 41 is rectangular, and the width of the rectangular gap is greater than the width of the anchoring shaft 5 and less than its length. This allows the anchoring shaft 5 to pass through the gap and move up and down when the width direction of the anchoring shaft 5 is aligned with the width direction of the gap. When the length direction of the anchoring shaft 5 is aligned with the width direction of the gap, the bottom of the anchoring shaft 5 is placed on top of the support plate 41.
[0034] In this embodiment, during the normal operation of the gantry crane, the bottom of the anchor shaft 5 is placed on the top of the support plate 41 to prevent the anchor shaft 5 from extending below the fixed cylinder 4 and affecting the movement of the gantry crane.
[0035] When anchoring is required, pull the anchoring shaft 5 upwards, then rotate the anchoring shaft 5 90° so that the width direction of the anchoring shaft 5 is consistent with the width direction of the gap. Then, drive the anchoring shaft 5 through the gap between the two support plates 41 so that the bottom of the anchoring shaft 5 is inserted into the corresponding anchoring groove 7 and fixed, thus completing the anchoring of the end beam.
[0036] Preferably, a lifting handle 52 is provided at the top of the anchoring shaft 5. Specifically, the lifting handle 52 facilitates the lifting action of the anchoring shaft 5.
[0037] Preferably, the groove of the anchoring groove 7 is rectangular and transitionally fits with the anchoring shaft 5. Specifically, the bottom of the anchoring groove 7 is fixed to the foundation by a mounting plate and bolts. The anchoring shaft 5 fits into the anchoring groove 7, which can stably fix the anchoring shaft 5 and also facilitate the removal of the anchoring shaft 5 from the anchoring groove 7.
[0038] Preferably, limiting plates 51 are provided on both outer walls along the length of the anchor shaft 5. Specifically, the limiting plates 51 are positioned in the middle of the anchor shaft 5. When the anchor shaft 5 is inserted into the anchor groove 7 and fixed, the limiting plates 51 are engaged with the top of the support plate 41, thus limiting the anchor shaft 5 and ensuring its stable insertion into the anchor groove 7, preventing the bottom of the anchor shaft 5 from contacting and rubbing against the bottom of the anchor groove 7.
[0039] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, positioning blocks 21 are fixedly installed at the ends of the upper anchor plate 2 and the lower anchor plate 3 away from the anchor bracket 1. Specifically, two positioning blocks 21 are provided on both the upper anchor plate 2 and the lower anchor plate 3. When fixing the end beam 8, the end beam 8 is inserted between the upper anchor plate 2 and the lower anchor plate 3. When the edge of the end beam 8 is aligned with the edge of the positioning block 21, the threaded hole on the end beam 8 corresponds to the bolt on the thread assembly. The positioning blocks 21 facilitate the quick and easy positioning of the end beam 8, improving the efficiency of fixing the end beam 8.
[0040] In a preferred embodiment, such as Figure 1 and Figure 3 As shown, shear blocks 22 are provided on both sides of the upper anchor plate 2 and the lower anchor plate 3 symmetrically about the positioning block 21. Specifically, two shear blocks 22 are provided on both the upper anchor plate 2 and the lower anchor plate 3, which can strengthen the structural strength of the two sides of the upper anchor plate 2 and the lower anchor plate 3. The shear blocks 22 are in contact with the upper and lower sides of the end beam 8. When the end beam 8 is torn by external forces, the two sides of the upper anchor plate 2 and the lower anchor plate 3 are not in direct contact with the end beam 8. Moreover, the shear blocks 22 have greater stiffness and are not easily deformed by external forces, thus improving the shear resistance of the anchoring device.
[0041] Working principle:
[0042] The gantry crane travels along the track, and multiple anchoring grooves 7 are fixedly installed on the foundation near the track. Before anchoring, the end beam 8 is firmly clamped by the upper anchoring plate 2 and the lower anchoring plate 3. Then, the upper and lower sides of the end beam 8 are fixed by the bolt group 6 on the upper anchoring plate 2 and the lower anchoring plate 3. Compared with the traditional anchoring method of welding to the web of the end beam, this application makes the upper and lower sides of the end beam 8 bear the force, making the end beam 8 bear the force more evenly, avoiding the end beam 8 from being deformed due to excessive local stress, making the mechanical structure more reasonable, and improving the stability of the anchoring device. During anchoring, the gantry crane is stopped at the anchoring position, and the anchoring shaft 5 is pulled upward by the lifting handle 52. Then, the anchoring shaft 5 is rotated 90° so that the width direction of the anchoring shaft 5 is aligned with the width direction of the rectangular gap between the two support plates 41. This causes the anchoring shaft 5 to move downward, and the bottom of the anchoring shaft 5 is inserted into the anchoring groove 7 for fixation, thus completing the anchoring of the gantry crane. The structure is simple and easy to implement, and the anchoring device can be disassembled, making it convenient to remove the anchoring device for maintenance and repair, and facilitating the normal operation and transportation of the gantry crane.
