Description

Technical Field

[0001] This application relates to the field of engineering machinery technology, specifically to a tie rod and guide pile assembly and a quay crane. Background Technology

[0002] A quay crane, also known as a quay gantry crane, has a front beam with a tilting function. Typically, the front beam is connected to the main steel structure of the quay crane via tie rods. When the front beam tilts up, the tie rods fold accordingly. However, because tie rods are slender members, they are unstable under pressure during folding. Therefore, existing technology often uses tie rod guide piles on the front beam. These guide piles usually consist of flared double-sided columns and supports, welded and fixed to the front beam. The width of the slots between the columns matches the width of the tie rods. During the tilting process, the tie rods are compressed and gradually fold into the guide piles. This prevents the tie rods from swaying and allows them to fold stably according to the designed folding method and angle, preventing structural damage or interference with surrounding components.

[0003] However, on the one hand, during the manufacturing stage of the quay crane, there are factors such as manufacturing errors, installation errors, tie rod deformation, and front beam deformation. On the other hand, during the use stage of the quay crane, there are factors such as wind load and deformation of the main steel structure of the quay crane. All of these factors can easily cause the tie rods to fail to fall into the tie rod guide piles normally. On-site, it is necessary to cut off the tie rod guide piles, re-determine the position and re-weld them, then grind the welds and repaint them. In addition, the tie rod guide piles weigh up to 1 ton, which makes the workload large and the implementation cost high. Summary of the Invention

[0004] In view of this, this application provides a tie rod and guide pile assembly and a quay crane to solve the problem in the prior art that the tie rod of the quay crane cannot fall into the tie rod guide pile normally, resulting in a large workload and high implementation cost for adjusting the tie rod guide pile.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A tie rod and guide post assembly, comprising:

[0007] The guide post has a slot with a width in the first direction;

[0008] Pull rod;

[0009] A guide base, the width of which is adapted to the width of the slot, and connected to the side of the tie rod facing the guide post;

[0010] In the first direction, the guide base is movable and fixed relative to the pull rod, so that the guide base is directly opposite the slot, and the width edge of the pull rod is always within the width edge of the guide base.

[0011] Optionally, one of the guide base and the pull rod is provided with an adjustment hole, and the other is provided with a positioning hole. The adjustment hole extends along the first direction, and the guide base and the pull rod are fastened together by a fastening assembly passing through the positioning hole and the adjustment hole.

[0012] Optionally, the depth of the slot is in the second direction; wherein,

[0013] The pull rod includes:

[0014] Tie rod middle plate;

[0015] A tie rod side plate is disposed opposite to the tie rod middle plate, is fixedly connected to the tie rod middle plate, and cooperates with the tie rod middle plate to form a tie rod groove;

[0016] The guide base includes:

[0017] The guide section is able to reach the bottom of the slot;

[0018] The connecting segment, along with the guide segment, is distributed sequentially in the second direction and extends into the tie rod groove and connects to the tie rod middle plate;

[0019] In the first direction, the connecting segment is movable in the tie rod groove, and the tie rod side plate is always located within the edge of the guide segment.

[0020] Optionally, the guide section is provided with a vertical plate extending along the second direction, and the tie rod side plate is at least partially located in the receiving space formed between the vertical plate and the connecting section.

[0021] Optionally, a reinforcing structure may also be included, which can be supported between the tie rod side plate and the upright plate to fix the relative position between the tie rod side plate and the upright plate.

[0022] Optionally, the reinforcement structure includes:

[0023] A reinforcing nut is attached to the side plate of the tie rod.

[0024] A reinforcing bolt is threadedly connected to the reinforcing nut along the first direction, passes through the tie rod side plate, and its end abuts against the upright plate.

[0025] Optionally, in the second direction, the guide segment tapers away from the connecting segment.

[0026] Optionally, the bottom of the slot is provided with a recess that matches the guide section.

[0027] Optionally, the guide pile includes:

[0028] Support;

[0029] The column is fixed to the support and is spaced apart in the first direction to form the slot;

[0030] The opening of the slot gradually widens in the direction away from the support.

[0031] A quay crane, comprising the guide pile assembly as described in any of the above.

[0032] The tie rod and guide post assembly provided in this application includes a guide post, a tie rod, and a guide base; the guide post has a slot with a width in a first direction; the guide base has a width that matches the width of the slot and is connected to the side of the tie rod facing the guide post; wherein, in the first direction, the guide base can move and be fixed relative to the tie rod so that the guide base is directly opposite the slot, and the width edge of the tie rod is always within the width edge of the guide base. With this configuration, the slot of the guide pile is no longer width-matched to the tie rod, but is instead widened. Simultaneously, the side of the tie rod facing the guide pile connects to a guide base, the width of which is greater than the width of the tie rod. Furthermore, the width of the guide base is compatible with the slot of the guide pile. Since the guide base can be fixed relative to the tie rod, when the guide base falls into the slot of the guide pile, the guide pile effectively limits and prevents swaying of the tie rod. If the tie rod or guide pile shifts, or the guide base cannot guide the tie rod into the guide pile—meaning the guide base and the slot of the guide pile are not aligned in the first direction—the relative position of the guide base and the tie rod in the first direction has an adjustment range. Therefore, while keeping both the tie rod and guide pile in their original positions, only the position of the guide base on the tie rod needs to be adjusted until the guide base is aligned with the slot of the guide pile again. This allows the guide base to guide the tie rod into the slot, solving the problem of high workload and implementation cost associated with adjusting the tie rod and guide pile after the tie rod fails to fall properly into the guide pile in existing technologies.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] like Figures 1-2 As shown, this application embodiment provides a tie rod and guide pile assembly, including a guide pile 1, a tie rod 2, and a guide base 3; the guide pile 1 is welded to the front beam 5, and multiple guide piles 1 are provided and spaced apart along the length direction of the front beam 5. The guide pile 1 has a slot 11 with a width in a first direction, which is the... Figure 2The guide base 3 is positioned along the X-axis; its width matches the width of the slot 11 and is connected to the side of the pull rod 2 facing the guide post 1, i.e., below the pull rod 2. In this first direction, the guide base 3 can move and be fixed relative to the pull rod 2, ensuring that the guide base 3 is directly opposite the slot 11, and the edge of the pull rod 2's width is always within the edge of the guide base 3's width. This means the width of the guide base 3 is greater than the width of the pull rod 2, ensuring that the guide base 3 guides the pull rod 2 into the slot 11. It should be noted that the guide post 1 functions only if the pull rod 2 can fall into the slot 11 without significant wobbling. Therefore, the width of the guide base 3 matching the width of the slot 11 means that the width of the guide base 3 is slightly smaller than the width of the slot 11. When they are directly opposite each other, the guide base 3 can fall precisely into the slot 11, satisfying the aforementioned prerequisite.

[0047] With this configuration, the slot 11 of the guide post 1 is no longer width-matched to the tie rod 2, but is instead widened. Simultaneously, the side of the tie rod 2 facing the guide post 1 is connected to the guide base 3. The width of the guide base 3 is greater than the width of the tie rod 2, and the width of the guide base 3 is matched with the slot 11 of the guide post 1. Since the guide base 3 can be fixed relative to the tie rod 2, when the guide base 3 falls into the slot 11 of the guide post 1, the guide post 1 effectively limits and prevents the tie rod 2 from shaking. If the tie rod 2 or the guide post 1 shifts, the guide base 3 will be unable to guide the tie rod 2 into the slot 11. In the case of guide pile 1, where the guide base 3 and the slot 11 of guide pile 1 cannot be aligned in the first direction, since the relative positions of guide base 3 and tie rod 2 in the first direction have an adjustment range, the position of guide base 3 on tie rod 2 can be adjusted only while tie rod 2 and guide pile 1 remain in their original positions until guide base 3 is aligned with slot 11 of guide pile 1 again. Guide base 3 can then guide tie rod 2 into slot 11, solving the problem of high workload and implementation cost of adjusting tie rod 2 and guide pile 1 after tie rod 2 cannot fall into guide pile 1 normally in the prior art.

[0048] Moreover, compared with the prior art, the solution provided in this application makes the width of the pull rod 2 smaller than the width of the slot 11, and the width difference is large, which also helps to reduce the possibility of the pull rod 2 colliding with the inner wall of the slot 11 during the folding process.

[0049] It should be noted that the length direction of the front girder 5 is the Y-axis direction in the figure. Since the front girder 5 needs to perform pitching motion in the quay crane, the Y-axis and Z-axis directions in the figure are based on the front girder 5 in the pitched state.

[0050] According to statistics on the offset between tie rod 2 and guide post 1 in the prior art, the offset distance is usually between 20mm and 40mm, including the endpoint values. Therefore, in this application, the relative position adjustment range between guide base 3 and tie rod 2 in the first direction is 20mm-40mm, including the endpoint values, that is, the distance traveled by guide base 3 from one extreme position to the other extreme position.

[0051] In one specific embodiment, such as Figures 3-5 As shown, one of the guide base 3 and the pull rod 2 is provided with an adjustment hole 31, and the other is provided with a positioning hole. The adjustment hole 31 extends along a first direction. The guide base 3 and the pull rod 2 are fastened together by a fastening assembly passing through the positioning hole and the adjustment hole 31. The adjustment hole 31 can be a slotted hole or a rectangular strip hole. The positioning hole is a round hole that fits the fastening assembly. The guide base 3 is provided with a slotted hole. The fastening assembly is a bolt and nut assembly or a screw and double nut assembly.

[0052] With this configuration, the guide base 3 and the pull rod 2 can be detachably connected, making production, design, and assembly convenient and quick. After loosening the fastening components, the guide base 3 can be adjusted relative to the pull rod 2. Once in position, the fastening components can be tightened again to secure the guide base 3 to the pull rod 2. Alternatively, one of the guide base 3 and the pull rod 2 can be fitted with a bolt, while the other has an adjustment hole 31. The bolt passes through the adjustment hole 31 and, with the help of a nut, securely connects the guide base 3 and the pull rod 2.

[0053] In another specific embodiment, the depth of the slot 11 is in the second direction, i.e. Figure 2 The Z-axis direction in; where,

[0054] The tie rod 2 includes a tie rod middle plate 21 and a tie rod side plate 22; the tie rod side plate 22 is arranged opposite to the tie rod middle plate 21, is fixedly connected to the tie rod middle plate 21 and cooperates with the tie rod middle plate 21 to form a tie rod groove 23, that is, the tie rod 2 is a commonly used I-beam or H-beam;

[0055] The guide base 3 includes a guide section 32 and a connecting section 33. The guide section 32 can reach the bottom of the slot 11 along the second direction. The connecting section 33 and the guide section 32 are distributed sequentially along the second direction and extend into the pull rod groove 23 and are connected to the pull rod middle plate 21. Specifically, the top surface of the connecting section 33 is provided with an oblong hole. In the first direction, during adjustment, the connecting section 33 can move along the first direction in the pull rod groove 23, and the pull rod side plate 22 is always located within the edge of the guide section 32. That is, when the connecting section 33 moves to the limit position in the pull rod groove 23, the pull rod side plate 22 is still within the edge of the guide section 32.

[0056] With this design, the guide base 3 is adapted to the conventional design of the tie rod 2. The connecting section 33 extends into the tie rod groove 23 for reliable connection. The guide section 32, which is wider than the connecting section 33, guides the tie rod 2 into the slot 11. The width of the guide section 32 is adapted to the width of the slot 11, and the guide section 32 can withstand the wear caused by possible collision with the guide pile 1. With this design, the original tie rod 2 can be used, resulting in low production or modification costs, strong practicality, and good performance.

[0057] In actual production and assembly, the guide base 3 can be a three-dimensional structure welded from multiple plates.

[0058] Based on the above, in a preferred embodiment, the widest edge of the guide section 32 is provided with a vertical plate 34 extending upward in the second direction, and the pull rod side plate 22 is at least partially located in the receiving space formed between the vertical plate 34 and the connecting section 33, that is, the bottom side of the pull rod side plate 22 is located in the receiving space.

[0059] With this configuration, the guide base 3 forms a semi-enclosed state for the pull rod 2, and the pull rod side plate 22 is protected by the upright plate 34. The upright plate 34 preferentially bears the impact that the guide base 3 may suffer when it falls into the slot 11, further ensuring that the pull rod 2 will not be impacted.

[0060] Furthermore, such as Figure 3 As shown, it also includes a reinforcing structure 4 disposed between the pull rod 2 and the guide base 3. The reinforcing structure 4 is located in the accommodating space and can be supported between the pull rod side plate 22 and the upright plate 34 to fix the relative position between the pull rod side plate 22 and the upright plate 34.

[0061] With this configuration, the connection between the guide base 3 and the tie rod 2 includes not only the connection between the connecting section 33 and the middle plate 21 of the tie rod, but also the reinforcement relationship between the relative positions of the tie rod side plate 22 and the upright plate 34. This strengthens the overall structural strength and connection strength of the guide base 3 and the tie rod 2. As a result, after the position between the guide base 3 and the tie rod 2 is adjusted and fixed, it is not easy for relative displacement to occur again, preventing the fastening components at the connecting section 33 from being subjected to shear force. Moreover, the inner side of the upright plate 34 has a load-bearing structure, which can reduce the possibility of deformation of the upright plate 34 due to collision and optimize the overall mechanical model of the guide base 3 and the tie rod 2.

[0062] Furthermore, the reinforcement structure 4 includes a reinforcement bolt 42 and a matching reinforcement nut 41; the reinforcement nut 41 is fixed to the tie rod side plate 22; the reinforcement bolt 42 is threadedly connected to the reinforcement nut 41 along the first direction, passes through the tie rod side plate 22 and its end abuts against the upright plate 34.

[0063] With this configuration, the reinforcing bolt 42 can be adjusted according to the change in the relative position between the guide base 3 and the tie rod 2, providing strong adaptability. Of course, in addition, it is also feasible to have threaded through holes on the tie rod side plate 22 and only provide reinforcing bolts 42 that are threadedly connected to the tie rod side plate 22; or, the accommodating space can be filled with a compressible pad as a reinforcing structure 4.

[0064] In another preferred embodiment, in the second direction, the guide segment 32 tapers away from the connecting segment 33, and preferably the guide segment 32 is V-shaped, so that the width of the widest part of the guide segment 32 is the width of the guide base 3.

[0065] With this configuration, the guide section 32 first reaches the slot 11 with a smaller width, which helps reduce the possibility of the guide base 3 colliding with the guide pile 1, allowing it to enter smoothly and optimizing the guiding effect.

[0066] Furthermore, the bottom of the slot 11 is preferably provided with a recess 12 that matches the guide section 32, or in other words, the recess 12 accommodates the guide section 32.

[0067] With this configuration, the guide section 32 is set to an irregular shape, and the bottom of the slot 11 is set to a matching recess 12, ensuring that the guide section 32 and the slot 11 have sufficient surface contact. This is beneficial to the good positional stability of the guide base 3 in the guide pile 1, thereby preventing the pull rod 2 from shaking in the slot 11.

[0068] In another specific embodiment, the guide pile 1 includes a support 13 and a column 14; the support 13 is used to weld to the front beam 5; the column 14 is fixed to the support 13, and the opposing columns 14 are spaced apart in a first direction and form slots 11; wherein, the opening of the slot 11 gradually expands in the direction away from the support 13, that is, in the second direction, it gradually expands from bottom to top.

[0069] This design makes it easier and faster for the guide base 3 to guide the tie rod 2 to fall into the guide pile 1.

[0070] Based on the aforementioned tie rod and guide pile assembly, this application also provides a quay crane including the aforementioned tie rod and guide pile assembly. Since this quay crane has the aforementioned tie rod and guide pile assembly, the beneficial effects brought by the tie rod and guide pile assembly are described above and will not be repeated here.
