Description

Technical Field

[0001] This utility model relates to the field of engineering safety protection equipment technology, and in particular to a windproof device for cranes. Background Technology

[0002] Currently, outdoor cranes such as various gantry cranes and portal cranes are equipped with a variety of wind-resistant safety devices. Among them, wind-resistant cable devices are almost universally available on every crane. These devices are used to prevent accidents caused by strong winds after the crane has been shut down (if it is scheduled to resume work the next day). This type of wind-resistant device consists of four wind-resistant cables. One end of each cable is connected to a corner beam at the bottom of the crane (such as a crossbeam or end beam), and the other end is connected to a wind-resistant cable holder on the dock surface. The four cables simultaneously hold the four corners of the crane, thus achieving wind protection.

[0003] However, the commonly used wind-resistant cable device currently in use has the following main structure and operation method: one end of the wind cable is connected to a lug plate on a corner beam of the crane (such as a crossbeam or end beam) via a shackle, and the other end of the wind cable is connected to a screw fastener for adjusting the length of the wind cable. This screw fastener is then connected to a cable support on the ground via a shackle. When the crane needs to operate, the wind cable device must be removed beforehand, mainly by disassembling the connection to the cable support on the ground. Then, the wind cable, screw fastener, and shackle connected to the screw fastener are lifted together and placed on the lower beam support of the crane.

[0004] The applicant found the following main deficiencies in the existing wind cable windproof device: 1) After the lower end of the wind cable is disconnected from the wind cable seat, the wind cable, the spiral buckle and the shackle connected to the spiral buckle weigh tens or even hundreds of kilograms. It is very inconvenient to lift and place it on the support of the crane beam. It is difficult for one operator to lift and place it, and there is also a risk of falling and injuring the operator; 2) The upper end of the wind cable is connected to the crane beam with multiple shackles. The upper end of the wind cable does not need to be disassembled in daily life. The structure is complex and the cost is high.

[0005] Chinese patent document CN223016333U discloses a lightweight crane anti-tipping safety cable installation structure. This structure uses connector one and connector two to fix the auger and upper windproof rope to the crane, thereby reducing the weight of the moving parts and reducing the difficulty of loading and unloading. However, the auger and shackle are still located on the crane, which makes it inconvenient to adjust the tension of the windproof rope, affecting the wind protection effect of the crane. It is also inconvenient to inspect and maintain the auger and shackle. At the same time, the auger and other parts wobble when the crane is running, and may collide with the crane beam, damaging the surface anti-corrosion layer and local structure, affecting the service life of the whole machine, and also posing a risk of falling. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a crane windproof device that is easy to load and unload, easy to maintain and adjust, and has good safety.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A crane windproof device includes a cable, a screw buckle, an anchoring pit in the ground, and an anchoring seat fixedly installed in the anchoring pit. The upper end of the cable is connected to the connecting part of the crane, and the lower end is detachably connected to the upper end of the screw buckle. The lower end of the screw buckle is connected to the anchoring seat. When the cable is detached from the screw buckle, the screw buckle is accommodated in the anchoring pit.

[0008] As a further improvement to the above technical solution: The anchoring pit includes a main pit section and a groove section located on one side of the main pit section. The anchoring seat is located in the main pit section, and the groove section is used to accommodate the spiral buckle.

[0009] The pit section is located on the side of the main pit section near the connection part of the crane.

[0010] The groove is elongated. When the cable is connected to the spiral buckle, the projection of the line connecting the anchor seat and the crane connection on the horizontal plane is consistent with the axial direction of the groove.

[0011] The upper end of the spiral buckle is provided with a shackle, and the upper end of the spiral buckle is detachably connected to the cable through the shackle.

[0012] The upper end of the cable is hinged to the connection part of the crane.

[0013] The crane windproof device also includes a lug mounted on the connecting part of the crane, and the upper end of the cable is hinged to the lug by a pin.

[0014] The anchoring pit is also equipped with a protective cover.

[0015] The top surface of the anchoring pit is the ground reference surface.

[0016] The cable, spiral buckle, anchor seat and anchor pit are provided in multiple sets along the circumference of the crane.

[0017] Compared with the prior art, the advantages of this utility model are: 1. The crane windproof device of this utility model detachably connects the cable and the screw buckle. After use, the cable only needs to be lifted and placed on the crane for fixing, which reduces the weight of the part that the operator needs to lift. The installation and removal are simple and convenient. After the screw buckle is removed, it is placed in the anchoring pit, which facilitates the inspection of the screw buckle and the adjustment of the cable tension. It also prevents the screw buckle from colliding with the crane beam and damaging the surface anti-corrosion layer and local structure, thus extending the service life of the whole machine. At the same time, it also reduces the risk of the screw buckle and related accessories falling, which is safe.

[0018] 2. The crane windproof device of this utility model has a spiral buckle that is closer to the crane than the anchor seat after the spiral buckle is connected and tightened to the cable. The groove is located on the side of the main pit that is closer to the crane, which makes it easier to place the spiral buckle in the groove after the cable is disassembled from the spiral buckle, making the operation more convenient.

[0019] 3. The crane windproof device of this utility model has a long strip-shaped groove that can match the shape of the screw buckle. When the cable is connected to the screw buckle placed in the anchoring pit and the cable is tightened by adjusting the screw buckle, the projection of the connection between the anchor seat and the crane on the horizontal plane is consistent with the axial direction of the groove, so that the screw buckle is gradually tightened and raised in the groove, preventing the screw buckle from colliding with the inner wall of the groove.

[0020] 4. The crane windproof device of this utility model has a cable that is hinged to the crane through a pin and a lug. Compared with the existing method of connecting the cable to the crane beam with multiple shackles, the structure is simpler, the connection is more convenient, and the cost is lower.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figures 1 to 3 As shown, the crane windproof device of this embodiment includes a cable 1, a screw buckle 2, an anchoring pit 4 opened in the ground, and an anchoring seat 3 fixedly installed in the anchoring pit 4. The upper end of the cable 1 is connected to the connecting part of the crane, and the lower end is detachably connected to the upper end of the screw buckle 2. The lower end of the screw buckle 2 is connected to the anchoring seat 3. When the cable 1 and the screw buckle 2 are disassembled, the screw buckle 2 is accommodated in the anchoring pit 4.

[0030] In this embodiment of the crane windproof device, the lower end of the cable 1 is connected to the screw buckle 2 placed in the anchoring pit 4, and the screw buckle 2 is adjusted to tighten the cable 1, thus achieving windproof protection for the crane. Before the crane starts working, the connection between the cable 1 and the screw buckle 2 is disassembled, the screw buckle 2 is placed in the anchoring pit 4, and then the cable 1 is lifted and fixed onto the crane beam support for use after the work stoppage. This embodiment of the crane windproof device, by detachably connecting the cable 1 and the screw buckle 2, reduces the weight that operators need to lift after use, making installation and removal easy and convenient. The screw buckle 2, after being disassembled and placed in the anchoring pit 4, facilitates the maintenance of the screw buckle 2 and the adjustment of the cable 1 tension, and prevents the screw buckle 2 from colliding with the crane beam, damaging the surface anti-corrosion layer and local structure, extending the overall lifespan of the machine. It also reduces the risk of the screw buckle 2 and related accessories falling, ensuring good safety.

[0031] Furthermore, in this embodiment, the anchoring pit 4 includes a main pit portion 41 and a groove portion 42 disposed on one side of the main pit portion 41. The anchoring seat 3 is disposed in the main pit portion 41, and the groove portion 42 is used to accommodate the spiral buckle 2. The anchoring pit 4 is composed of two parts: the main pit portion 41 and the groove portion 42. The anchoring seat 3 is located in the main pit portion 41, and the disassembled spiral buckle 2 is located in the groove portion 42. The structure is simple.

[0032] Furthermore, in this embodiment, the groove portion 42 is located on the side of the main groove portion 41 near the crane's connection portion. Since the spiral buckle 2 is closer to the crane than the anchor seat 3 after it is connected and tightened to the cable 1, the groove portion 42 is located on the side of the main groove portion 41 near the crane, making it easier to place the spiral buckle 2 in the groove portion 42 after the cable 1 and spiral buckle 2 are disassembled, thus making the operation more convenient.

[0033] Furthermore, in this embodiment, the groove portion 42 is elongated. When the cable 1 is connected to the screw buckle 2, the projection of the connection between the anchor seat 3 and the crane on the horizontal plane is consistent with the axial direction of the groove portion 42. The elongated groove portion 42 can match the shape of the screw buckle 2. During the process of adjusting the screw buckle 2 to tighten the cable 1 after the cable 1 is connected to the screw buckle 2 placed in the anchoring pit 4, the screw buckle 2 gradually tightens and rises within the groove portion 42 because the projection of the connection between the anchor seat 3 and the crane on the horizontal plane is consistent with the axial direction of the groove portion 42, preventing the screw buckle 2 from colliding with the inner wall of the groove portion 42.

[0034] Preferably, in this embodiment, the pit portion 42 is rectangular, which is convenient for construction. Of course, in other embodiments, the pit portion 42 may also be cylindrical or other elongated shapes, or other shapes.

[0035] Furthermore, in this embodiment, the upper end of the spiral buckle 2 is provided with a shackle 21, and the upper end of the spiral buckle 2 is detachably connected to the cable 1 through the shackle 21. The spiral buckle 2 is detachably connected to the cable 1 through the shackle 21, which is simple in structure and easy to use. Of course, in other embodiments, the spiral buckle 2 and the cable 1 can also adopt other detachable connection methods.

[0036] Furthermore, in this embodiment, the upper end of the cable 1 is hinged to the connection part of the crane.

[0037] Furthermore, in this embodiment, the crane windproof device also includes a lug 51 disposed on the connecting part of the crane, and the upper end of the cable 1 is hinged to the lug 51 by a pin 52. The cable 1 is hinged to the crane by the pin 52 and the lug 51. Compared with the existing method of using multiple shackles 21 to connect the cable 1 to the crane beam, the structure is simpler, the connection is more convenient, and the cost is lower.

[0038] Furthermore, in this embodiment, a protective cover 6 is also provided on the anchoring pit 4. The protective cover 6 is located above the main pit 41 and the pit groove 42, which can prevent debris from entering the pit and prevent personnel from accidentally stepping in and getting injured, making it highly practical.

[0039] Furthermore, in this embodiment, the top surface of the anchoring pit 4 is the ground reference plane. The anchoring pit 4 is lower than the ground reference plane, and after the screw buckle 2 is removed and placed into the anchoring pit 4, it does not affect the normal passage of vehicles, etc.

[0040] Furthermore, in this embodiment, multiple sets of cables 1, screw buckles 2, anchor seats 3, and anchor pits 4 are provided along the circumference of the crane. These multiple sets of cables 1, screw buckles 2, anchor seats 3, and anchor pits 4 can anchor the crane in multiple directions, resulting in more stable anchoring and better wind resistance.
