Description

Technical Field

[0001] The utility model relates to the technical field of lifting hooks, in particular to an inclined hook storage rack. Background Art

[0002] During the loading and unloading operation of maritime transportation, in order to facilitate the loading and unloading of goods, a crane for hoisting goods is often provided at the bow of the ship. The crane is provided with a boom, and a steel wire rope is provided on the boom, and the steel wire rope is connected to a lifting hook. After the crane finishes hoisting, that is, when the lifting hook of the crane is in a non-working state, it is necessary to store the lifting hook to prevent the lifting hook from swinging greatly when the ship encounters wind and waves, and eliminate potential safety hazards in the non-operation state.

[0003] For example, in the patent document with the Chinese patent application number 202211107688.4 and the publication date of January 31, 2023, it discloses a shipborne hook storage mechanism and a cargo ship. The shipborne hook storage mechanism includes a storage rack. One side of the storage rack is fixedly connected to the hull. The middle part of the upper end of the hook box is rotatably connected to the other side of the storage rack, and the rotation center line of the hook box extends along the left-right direction; the hook box is provided with a receiving groove for receiving the lifting hook. The opening of the receiving groove faces upward, and the lifting hook is arranged in the receiving groove. The lifting hook and the hook box form a balance pulley, and the center of mass of the balance pulley is located below the rotation center line of the hook box.

[0004] The above document discloses the specific structure of the hook box; however, since the ship is sailing on the sea, it is easy for the lifting hook to swing at too large an angle under the action of sea waves and wind and waves. At this time, the distance between the lifting hook and the boom is relatively large, making it difficult for the operator to quickly and accurately place the lifting hook back into the hook box. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an inclined hook storage rack, which can quickly and accurately store and place the lifting hook, saving time and effort, and at the same time ensuring the stability of the hook placement.

[0006] To achieve the above purpose, an inclined hook storage rack is applied to the placement of the lifting hook of a crane, including a bracket and a limiting device. The bracket includes a first bracket and a second bracket. The first bracket and the second bracket are fixedly connected by a connecting column. An included angle is formed between the first bracket and the second bracket at the fixed connection, and the angle of the included angle is 30°-45°. The second bracket is provided with an inclined surface, and buffer pads are fixedly arranged along the length direction of the second bracket on the inclined surface. The limiting device includes two or more limiting blocks. Limiting openings are formed between the limiting blocks located on the inclined surface. The limiting blocks are symmetrically arranged on both sides of the buffer pad with respect to the axis where the limiting opening is located and are perpendicular to the inclined surface. The limiting blocks are provided with inclined portions on one side of the limiting opening.

[0007] With the above settings, by setting the first bracket and the second bracket and making the included angle between the first bracket and the second bracket an acute angle, when the bracket is placed upright, the second bracket can be inclined with respect to the first bracket, facilitating the hook to be placed on the second bracket along the inclined surface of the second bracket. By providing a buffer gasket on the inclined surface, the friction between the hook and the inclined surface during the lowering process can be reduced, and at the same time, the inclined surface can support the hook. In addition, by providing limit blocks on both sides of the inclined surface, after the hook slides down a certain distance along the inclined surface, the limit blocks can block the hook from sliding down, enabling the hook to stop on the bracket, thus quickly achieving stable placement of the hook and saving manpower and time.

[0008] Furthermore, the limit blocks are arranged oppositely. A connecting portion is provided on one side of the limit block located at the limit opening, and the connecting portion is connected to the inclined portion.

[0009] With the above settings, it is convenient for the hook to slide into the limit opening along the inclined portion.

[0010] Furthermore, the included angle formed by connecting one end of the inclined portion to the top of the limit block is 120° - 135°, the included angle formed by connecting the other end of the inclined portion to one end of the connecting portion is 135° - 150°, and the other end of the connecting portion is perpendicularly connected to the bottom of the limit block.

[0011] With the above settings, the inclined portion can limit the hook that has slid into the limit opening, causing both sides of the hook to abut against the inclined portion, and the inclined portion to exert an obliquely upward and outward force on the hook, thereby stopping the hook on the second bracket.

[0012] Furthermore, the width between the inclined portions is greater than or equal to the width between the connecting portions.

[0013] With the above settings, it is convenient for the hook to pass through between the connecting portions, and both sides of the pulley on the hook are clamped on the inclined portions, thereby stably fixing the hook on the second bracket.

[0014] Furthermore, a support rod is provided at the bottom of the limit block. One end of the support rod is fixedly connected to the bottom of the limit block, and the other end of the support rod passes through the second bracket and abuts against the contact plane.

[0015] With the above settings, the support rod supports the limit block.

[0016] Furthermore, the width of the pulley on the hook is greater than the width between the inclined portions.

[0017] With the above settings, it is convenient for the inclined portions to clamp both sides of the pulley on the hook, thereby stopping the hook between the limit blocks for placement.

[0018] Further, more than two connecting rods are provided between the first bracket and the second bracket, and both ends of the connecting rods are fixedly connected to the first bracket and the second bracket respectively.

[0019] The above setting can strengthen the stability between the first bracket and the second bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0026] As Figures 1 to 5 shown, a slope - type hook storage rack is applied to the placement of the hook of a crane, and includes a bracket and a limiting device. The bracket includes a first bracket 1 and a second bracket 2. One end of the first bracket 1 is fixedly connected to one end of the second bracket 2 through a connecting column 3. An included angle a is formed between the first bracket 1 and the second bracket 2 at the connection. The angle of the included angle a is 30° - 45°. In this embodiment, the angle of the included angle a is 30°. An inclined surface 21 is provided on the second bracket 2. Along the length direction of the second bracket 2, a buffer gasket 22 is fixedly provided on the inclined surface 21. As Figure 3 shown, more than two countersunk holes 23 are provided on the buffer gasket 22. The buffer gasket 22 is fixed on the inclined surface 21 by bolts 24 passing through the countersunk holes 23. In this way, during the lowering process of the hook z1, the sliding friction between the hook z1 and the inclined surface 21 can be reduced, and the hook z1 can slide down along the inclined surface 21 under the action of its own gravity and slide into the limiting opening 5. In this embodiment, the buffer gasket 22 is a sleeper.

[0027] As Figure 1 、 2As shown in FIGS. 4 and 5, the limiting device includes more than two limiting blocks 4. In this embodiment, the number of the limiting blocks 4 is set to two. The limiting blocks 4 are oppositely arranged on the inclined surface 21. A limiting opening 5 is formed between the two limiting blocks 4. The two limiting blocks 4 are symmetrically arranged on both sides of the buffer gasket 22 with respect to the axis 6 where the limiting opening 5 is located and are perpendicular to the inclined surface 21. An inclined portion 41 and a connecting portion 42 are provided on one side of the limiting block 4 located at the limiting opening 5. The connecting portion 42 is connected to the inclined portion 41. As shown in the figure, one end of the inclined portion 41 is connected to the top of the limiting block 4 to form an included angle b, and the angle of the included angle b is 110° - 125°. The other end of the inclined portion 41 is connected to one end of the connecting portion 42 to form an included angle c, and the angle of the included angle c is 145° - 160°. The other end of the connecting portion 42 is perpendicularly connected to the bottom of the limiting block 4. In this embodiment, the angle of the included angle b is 110°, and the angle of the included angle c is 160°. In this way, the inclined portion 41 can limit the hook z1 sliding into the limiting opening 5, so that both sides of the pulley z2 on the hook z1 are abutted against the inclined portion 41, and the inclined portion 41 generates an obliquely upward and outward acting force on both sides of the pulley z2 on the hook z1, so that the pulley z2 on the hook z1 is clamped between the inclined portions 41, and further the hook z1 is stalled on the second bracket 2.

[0028] As Figure 4 and 5 shown, the width of the pulley z2 on the hook z1 is greater than the width between the inclined portions 41, and the width between the inclined portions 41 is greater than or equal to the width between the connecting portions 42, which is convenient for the hook z1 to pass through between the connecting portions 42. The inclined portions 41 are used to clamp both sides of the pulley z2 on the hook z1, so as to stop the hook z1 between the limiting blocks 4 for shelving.

[0029] As Figure 1 shown, a support rod 7 is provided at the bottom of the limiting block 4. One end of the support rod 7 is fixedly connected to the bottom of the limiting block 4, and the other end of the support rod 7 passes through the second bracket 2 and abuts against the contact plane. More than two connecting rods 8 are provided between the first bracket 1 and the second bracket 2. Both ends of the connecting rod 8 are fixedly connected to the first bracket 1 and the second bracket 2 respectively, so as to strengthen the stability between the first bracket 1 and the second bracket 2.

[0030] The working principle of the present utility model: The second bracket 2 and the first bracket 1 are inclined, then an inclined surface 21 is formed on the second bracket 2, and a buffer gasket 22 is arranged on the inclined surface 21. Then, opposite limiting blocks 4 are arranged on both sides of the buffer gasket 22. The limiting blocks 4 are used to limit the hook z1 sliding along the inclined surface 21, so that after the hook z1 slides along the inclined surface 21 into the limiting opening 5, it stays on the second bracket 2, playing a shelving role for the hook z1. In this way, the hook z1 can be quickly and stably shelved on the bracket, saving time and effort.
