Description
Technical Field
[0001] The present application relates to the technical field of building construction, and in particular to a crane hook anti-unhooking device. Background Art
[0002] Crane hook is the most common type of lifting equipment in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism with the help of components such as pulleys.
[0003] In construction, strong winds are often encountered, which can easily cause the lifting rope of the hoisted object to fall off the hook. Therefore, how to prevent the lifting rope from falling off the crane hook is a technical problem that needs to be solved urgently. Utility Model Content
[0004] The present application provides a crane hook anti-unhooking device, which can effectively reduce the risk of a lifting rope being unhooked from the crane hook.
[0005] To achieve the above objectives, this application provides the following technical solutions:
[0006] The present application provides a crane hook anti-unhooking device, comprising a hook body, a locking piece and an anti-unhooking ring. The hook body has a connecting end and a free end that are far away from each other, the connecting end and the free end are spaced apart to form a lifting cavity, the lifting cavity has an opening, and the connecting end is used to connect with the movable pulley block structure of the crane. The locking piece is adjustably arranged at the connecting end. The anti-unhooking ring is passed through and hinged to the free end, and the anti-unhooking ring is used to lock and cooperate with the locking piece to switch between an open opening state or a closed opening state.
[0007] In the above scheme, the anti-unhooking device of the crane hook is used to prevent the lifting object from unhooking, so that the lifting object can be stably hooked in the hook body. Exemplarily, the anti-unhooking ring is located on the locking member, and the opening is open. The worker passes the lifting rope of the lifting object through the opening to hook it in the lifting cavity of the hook body, and then rotates the anti-unhooking ring so that the anti-unhooking ring is hung on the locking member and adjusts the position of the locking member, thereby realizing the mutual locking of the anti-unhooking ring and the locking member to close the opening and prevent the lifting rope from unhooking. When the lifting rope is to be removed, the position of the locking member is adjusted to release the mutual locking of the anti-unhooking ring and the locking member, and the anti-unhooking ring is rotated to open the opening, so as to remove the lifting rope from the lifting cavity.
[0008] According to some embodiments of the present application, the lifting cavity is through-connected along a first direction, and a through hole is formed at the free end, and the through hole passes through the free end along the first direction;
[0009] The anti-drop ring is passed through the through hole and can rotate along the axis of the through hole.
[0010] According to some embodiments of the present application, the hook body includes a main body portion and an attachment portion, the attachment portion is detachably connected to the main body portion, and an end of the attachment portion away from the main body portion is a free end.
[0011] In the above scheme, since the mounting portion is provided, the anti-slip ring can be disassembled along with the disassembly of the mounting portion, so that the anti-slip ring of the crane hook has the function of replacing the anti-slip ring. In some embodiments, the anti-slip ring of the crane hook can be improved on the existing hook, the main body can be the existing hook, and the mounting portion can be a structural member installed on the hook later.
[0012] According to some embodiments of the present application, the mounting portion is connected to the main body portion via a screw.
[0013] According to some embodiments of the present application, the connecting end has a notch, the notch is arranged toward the second direction, the first direction and the second direction are perpendicular to each other, and the locking member is configured to be adjustably arranged in the notch along the second direction.
[0014] In the above solution, the anti-slip ring can be locked between the notch and the locking member, or the anti-slip ring can be unlocked by adjusting the position of the locking member in the second direction.
[0015] According to some embodiments of the present application, a slot is formed at the connection end, the slot extends along the second direction and communicates with the notch, and the locking member is inserted into the slot;
[0016] The connection end is formed with a latch hole, which is communicated with the slot; the locking piece is formed with a through hole, which is used to correspond to the latch hole for the latch to be inserted.
[0017] In the above solution, the position of the locking member in the second direction can be adjusted by pulling out the latch; and the locking member can be fixed by inserting the latch and passing the latch through the through hole of the locking member.
[0018] For example, when the locking between the anti-drop ring and the locking member is required, the latch is pulled out to make the locking member come out of the slot, so that the locking member is away from the notch in the second direction, so that the anti-drop ring can be taken out. When locking is required, the anti-drop ring is hung on the locking member and the locking member is pushed into the slot so that the through hole and the latch hole are aligned, and then the latch is inserted.
[0019] According to some embodiments of the present application, the locking member includes a slider and a baffle, the slider extends along the second direction, the baffle extends along the third direction and is arranged at the end of the slider, the baffle is located outside the slot, the slider can slide to cooperate with the slot, and the first direction, the second direction and the third direction are perpendicular to each other.
[0020] In the above solution, the baffle can effectively limit the rotation of the anti-slip ring to play a locking role.
[0021] According to some embodiments of the present application, the locking member further includes a limiting plate, wherein along a third direction, one end of the limiting plate is connected to the sliding block, and the other end of the limiting plate is connected to the limiting plate, and the limiting plate extends toward the slot.
[0022] In the above solution, the setting of the limit plate can effectively limit the rotation of the anti-slip ring, thereby improving the anti-slip effect. BRIEF DESCRIPTION OF THE DRAWINGS
