Description

Technical Field

[0001] This invention relates to the field of hook fixing equipment technology, and more particularly to a rotating hook box. Background Technology

[0002] In the field of lifting machinery products, as the application areas of cranes continue to expand, the requirements for the safe working load and lifting height of cranes are also increasing. For example, for offshore cranes and offshore wind power installation cranes, the safe working load and lifting height of the crane hook are large, and the self-weight of the hook also needs to be greater.

[0003] For example, when an offshore wind turbine installation crane is installed on an offshore wind turbine crane vessel, in order to save on deck layout control, the crane boom extends beyond the ship's side when it is resting. Under normal conditions, when the boom is resting, the hook will be raised to a position close to the boom head. This setting will cause the hook to swing due to the movement of the ship, which may easily collide with the boom structure or cause excessive twisting of the hook's wire rope, resulting in wire rope damage. In order to avoid the safety hazards caused by the swinging hook, the existing technology generally lowers the hook to a certain height and then places the hook in a hook box fixed on the deck.

[0004] However, the opening of the hook box in the existing technology is relatively small, and the hook is usually far away from the crane operator's cab. Affected by sea waves, the operation of placing the hook in the hook box is relatively laborious. It requires additional manual assistance to accurately align the hook before it can be put into the hook box. The whole process is time-consuming, laborious and inconvenient to operate.

[0005] Therefore, the existing technology has at least the following technical problems: the hook box in the existing technology requires the hook to be precisely aligned before it can be put in, which makes it inconvenient and inefficient to put the hook into the hook box. Summary of the Invention

[0006] This application provides a rotating hook box, which solves the technical problem in the prior art that the hook box can only be put in after the hook is precisely aligned, making it inconvenient and inefficient to put the hook into the hook box.

[0007] To address the aforementioned technical problems, this application provides a rotating hook box for accommodating lifting hooks, the rotating hook box comprising:

[0008] The first jaw component is fixedly connected to the base body;

[0009] The second jaw piece is movably disposed on one side of the first jaw piece. The second jaw piece is provided with an abutment portion. The second jaw piece can rotate relative to the first jaw piece when the hook pushes the abutment portion downward in the height direction, so that the second jaw piece and the first jaw piece enclose each other to form a box-like state, and the hook is stored in the enclosed box-like state.

[0010] Furthermore, the bottom of the second jaw member is hinged to the base, and the second jaw member is disposed on one side of the first jaw member, thereby rotating relative to the first jaw member.

[0011] Furthermore, a locking device is provided between the first jaw piece and the second jaw piece. When the second jaw piece rotates to form a box-like state with the first jaw piece, the locking device can fix the first jaw piece and the second jaw piece.

[0012] Furthermore, the first jaw member and the second jaw member are respectively provided with a positioning groove, and the first jaw member or the second jaw member is provided with a movable shaft pin. When the second jaw member rotates to form a box state with the first jaw member, the shaft pin can be inserted into the two positioning grooves so that the second jaw member is fixed in the current position.

[0013] Furthermore, the abutting portion is inclined relative to the main body portion of the second jaw member.

[0014] Furthermore, the abutting portion is perpendicular to the main body of the second jaw member, and the abutting surface of the abutting portion for contacting the hook is a gradually thinning arc-shaped guide surface.

[0015] Furthermore, a protective chain lock is connected between the first jaw piece and the second jaw piece, and the protective chain lock is used to limit and constrain the rotation angle of the second jaw piece.

[0016] Furthermore, the first jaw piece is fixed vertically relative to the base.

[0017] Furthermore, the box formed by the first jaw member and the second jaw member is open.

[0018] Furthermore, the first jaw plate is provided with a jaw for accommodating the second jaw plate. The first jaw plate can extend into or out of the jaw. When the first jaw plate extends into the jaw, the first jaw plate and the second jaw plate engage to form the box body.

[0019] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0020] (1) The rotating hook box provided by the present invention has a first jaw piece fixedly connected to the base body and a second jaw piece that can rotate relative to the base body. When the hook pushes the abutting part of the second jaw piece along the height direction, the second jaw piece rotates under the gravity of the hook and eventually rotates to form a box with the first jaw piece. As the hook moves downward along the height direction, the hook is also stored in the enclosed box, thus eliminating the need for alignment work of aligning the hook with the opening of the box in the prior art, reducing the difficulty of entering the hook box when the hook swings too much due to wind and waves, making the operation simple and convenient, and effectively improving the operation efficiency when the hook is placed in the hook box.

[0021] (2) The abutting part is located below the second jaw member. This arrangement ensures that when the hook abuts against the abutting part, it has already extended into the second jaw member, thereby ensuring that the rotated second jaw member can restrain the hook in the formed box.

[0022] (3) The contact surface of the abutment part for contacting the hook is a gradually thinning arc guide surface. When the hook contacts the abutment part, the smooth guide surface can guide the hook to move down gradually and ensure that it always contacts the hook, thereby preventing the second jaw piece from separating from the first jaw piece; and the smooth guide surface also makes it easy for the hook to be pulled out from the box formed by the first jaw piece and the second jaw piece.

[0023] (4) The box formed by the first jaw piece and the second jaw piece is open-mouthed. The two bends form a wider opening than the lower cavity. This setting can guide the hook into the lower end of the second jaw piece, thereby further reducing the difficulty of aligning the hook and entering the box.

[0024] (5) A protective chain lock is connected between the first jaw piece and the second jaw piece. The protective chain lock is used to limit and constrain the rotation angle of the second jaw piece. The protective chain lock 5 can limit the rotation angle of the second jaw piece and prevent the second jaw piece from rotating too much relative to the first jaw piece, which would prevent it from being able to enclose the box with the first jaw piece.

[0025] (6) A locking device is provided between the first jaw piece and the second jaw piece. When the second jaw piece rotates to form a box-like state with the first jaw piece, the locking device can fix the first jaw piece and the second jaw piece to maintain a stable box-like state.

[0026] (7) The first jaw plate is provided with a bite for accommodating the second jaw plate. The first jaw plate can extend into or out of the bite, so that the first jaw plate and the second jaw plate can form a relatively closed box. Attached Figure Description

[0035] This application provides a rotating hook box, which solves the technical problem in the prior art that the hook box can only be put in after the hook is precisely aligned, making it inconvenient and inefficient to put the hook into the hook box.

[0036] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0037] The rotating hook box of this application embodiment includes a first jaw and a second jaw member. The first jaw member is fixedly connected to the base, and the second jaw member rotates relative to the first jaw member. When the hook pushes the abutting part of the second jaw member along the height direction, the second jaw member rotates under the gravity of the hook and eventually rotates to form a box with the first jaw member. Since the hook itself is heavy, as the hook moves downward along the height direction, the hook is also stored in the box formed by the enclosure. This eliminates the need for the hook to be aligned with the opening of the box in the prior art, reduces the difficulty of the hook entering the hook box when the swing amplitude of the hook is too large due to wind and waves, and is simple and convenient to operate. It effectively improves the operating efficiency of placing the hook in the hook box and effectively solves the technical problem that the hook box in the prior art requires the hook to be accurately aligned before it can be put in, which makes it inconvenient and inefficient to put the hook into the hook box.

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] One or more embodiments of this application provide a rotating hook box, such as Figures 1 to 3 As shown, the rotating hook box is used to store the crane hook 8. The rotating hook box includes a first jaw 1 and a second jaw 2. The first jaw 1 is fixedly connected to the base. The bottom of the second jaw 2 is hinged to the base. The second jaw 2 is provided with an abutment part 6. The second jaw 2 can rotate relative to the base when the hook 8 pushes the abutment part 6 downward in the height direction, so that the second jaw 2 and the first jaw 1 enclose each other to form a box, and store the hook 8 in the enclosed box.

[0040] As can be seen from the above description, the rotating hook box provided in this application embodiment has a first jaw member 1 fixedly connected to the base, and a second jaw member 2 that can rotate relative to the base. When the hook 8 pushes the abutting part 6 of the second jaw member 2 along the height direction, the second jaw member 2 rotates under the gravity of the hook 8, and finally rotates to form a box state with the first jaw member 1. Since the hook 8 itself is heavy, as the hook 8 moves downward along the height direction, the hook 8 is also stored in the box formed by the enclosure. This eliminates the need for the hook 8 to be aligned with the opening of the box in the prior art, reduces the difficulty of the hook 8 entering the hook box when the swing amplitude is too large due to wind and waves, and makes the operation simple and convenient, effectively improving the operating efficiency when the hook 8 is placed in the hook box.

[0041] It should be noted that in each embodiment of this application, the offshore wind power crane vessel is used as the main object of the hook 8 for description. Based on this, the aforementioned base is the hull deck of the offshore wind power crane vessel, which will not be described again in the following text.

[0042] In some embodiments, the second jaw member 2 may also be movably disposed on the first jaw member 1. For example, the first jaw member 1 may have a mounting member extending toward the second jaw member 2, and the second jaw member 2 may be rotatably disposed on the mounting member. The key is to ensure that the second jaw member 2 can rotate relative to the first jaw member 1 as the hook 8 pushes the abutment portion 6 downwards in the height direction, so that the second jaw member 2 and the first jaw member 1 enclose each other to form a box-like state, and the hook 8 is housed within the enclosed box.

[0043] In some embodiments, the first jaw member 1 is fixedly arranged vertically relative to the base. The first jaw member 1 can be fixed to the deck by welding or by bolts, as long as the relative fixed state between the first jaw member 1 and the base is maintained.

[0044] In some embodiments, for example, the hinged connection between the second jaw member 2 and the base can be achieved by a pivot pin 3, that is, a boss is constructed on the base, and a through hole is provided on the second jaw member 2, and the pivot pin passes through the boss and the through hole together, thereby forming a hinged connection between the second jaw member 2 and the base.

[0045] In some embodiments, such as Figure 3 As shown, the aforementioned abutting part 6 is inclined relative to the main body of the second jaw member 2. Specifically, the abutting part 6 is perpendicular to the main body of the second jaw member 2, and the abutting surface 7 of the abutting part 6 for contacting the hook 8 is a gradually thinning arc-shaped guide surface.

[0046] In the above embodiment, the abutment portion 6 is disposed opposite to the lower part of the second jaw member 2. This arrangement ensures that when the hook 8 abuts against the abutment portion 6, it has already extended into the second jaw member 2, thereby ensuring that the rotated second jaw member 2 can constrain the hook 8 within the formed housing. The abutment surface 7 of the abutment portion 6 for contacting the hook 8 is a gradually thinning arc-shaped guide surface. Specifically, the end of the abutment portion 6 away from the main body of the second jaw member 2 is gradually thinned, such as... Figure 3 As shown, Figure 3 The direction of the middle arrow is the rotation direction of the second jaw piece 2. When the hook 8 contacts the abutment part 6, the smooth guide surface can guide the hook 8 to move down gradually and ensure that it always abuts the hook 8, thereby preventing the second jaw piece 2 from separating from the first jaw piece 1. The smooth guide surface also makes it easy for the hook 8 to be pulled out from the box formed by the first jaw piece 1 and the second jaw piece 2 for reuse.

[0047] In some embodiments, a locking device is provided between the first jaw member and the second jaw member. When the second jaw member rotates to form a box-like state with the first jaw member, the locking device can fix the first jaw member and the second jaw member to maintain a stable box-like state.

[0048] Specifically, such as Figure 2 As shown, the locking device 4 includes a positioning groove respectively disposed on the first jaw piece 1 and the second jaw piece 2, and a pivot pin movably disposed on the first jaw piece 1. When the second jaw piece 2 rotates to form a box state with the first jaw piece 1, the pivot pin can be inserted into the two positioning grooves to fix the second jaw piece 2 in the current position, thereby locking the box state formed by the second jaw piece 2 and the first jaw piece 1.

[0049] As an alternative implementation, the locking device 4 can also be provided on the second jaw member 2, as long as the shaft pin can pass through the positioning grooves of the first jaw member 1 and the second jaw member 2 together.

[0050] As an alternative implementation, exemplarily, a pawl can also be provided on the second jaw member 2. When the second jaw member 2 rotates to form a box-like state with the first jaw member 1, the pawl engages with a portion of the first jaw member 1 to form a fixed connection. Here, the locking device 4 is only described exemplarily in this embodiment. Any device that can lock or unlock the first jaw member 1 and the second jaw member 2 is acceptable and is not limited here.

[0051] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, a protective chain lock 5 connects the first jaw member 1 and the second jaw member 2. The protective chain lock 5 is used to limit and constrain the rotation angle of the second jaw member 2. Here, the length of the protective chain lock 5 is the chord length corresponding to the angle formed by the first jaw member 1 and the second jaw member 2. Setting the protective chain lock 5 can limit the rotation angle of the second jaw member 2, preventing the second jaw member 2 from rotating too much relative to the first jaw member 1, which would prevent it from being able to enclose the box with the first jaw member 1.

[0052] In some embodiments, the box formed by the first jaw member 1 and the second jaw member 2 is open. Specifically, the side of the first jaw member 1 facing the second jaw member 2 has a smooth transition bend, and the side of the second jaw member 2 facing the first jaw member 1 has a smooth transition bend. During the process of the first jaw member 1 and the second jaw member 2 forming the box, the two bends together form an opening that is wider than the lower cavity. This arrangement can guide the hook 8 into the lower end of the second jaw member 2, thereby further reducing the difficulty of aligning the hook 8 and entering the box.

[0053] In some embodiments, such as Figure 4 As shown, the first jaw plate 1 is provided with a jaw opening 11 for accommodating the second jaw plate 2. The first jaw plate 1 can extend into or out of the jaw opening 11. When the first jaw plate 1 extends into the jaw opening 11, the first jaw plate 1 and the second jaw plate 2 engage to form the housing. With this arrangement, when the first jaw plate 1 extends into the jaw opening 11, the first jaw plate 1 and the second jaw plate 2 can form a relatively closed housing.

[0054] The operation process of the rotating hook box provided in this embodiment is as follows:

[0055] In the initial state, the second jaw piece 2 is far away from the first jaw piece 1, and the protective chain lock 5 is taut. The hook 8 extends along the second jaw piece 2 and contacts the abutment part 6 of the second jaw piece 2. At this time, as the hook 8 continues to move downward, the abutment part 6 is driven by the gravity of the hook 8 to rotate the second jaw piece 2 towards the first jaw piece 1, gradually forming an enclosed box-like state. When the hook 8 extends along the edge of the abutment surface 7 and disengages from the abutment part 6 to contact the base, it just completes the enclosed box-like state. Finally, the locking device 4 is used to fix the second jaw piece 2 in this state, thus completing the storage of the hook 8.

[0056] When it is necessary to remove the hook 8, first use the locking device 4 to release the locking device of the second jaw piece 2, and then move the hook 8 vertically upward in the height direction.

[0057] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0058] (1) The rotating hook box provided by the present invention has a first jaw piece fixedly connected to the base body and a second jaw piece that can rotate relative to the base body.
