Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting clamps, and more specifically to a full-mode lifting clamp. Background Art
[0002] In heavy industry, large and heavy products may be difficult to handle manually. Therefore, a lift connected to a clamping device may be used to lift and move heavy objects. The object may be clamped to a clamping device coupled to the lift. The lift can lift the object to a certain height and then transfer it to the appropriate location.
[0003] The clamping device may utilize a mechanism that converts the weight of the object into a clamping force, so that the clamping force applied by the clamping device on the object may be proportional to the weight of the object.
[0004] A Chinese patent (publication number: CN108455448B) discloses a clamping device for lifting and transferring objects, which also includes: a locking mechanism, wherein the locking mechanism is configured to fix the clamping claw support to the clamping rod at discrete positions. The specific embodiments of the patent and the drawings in the specification show locking mechanisms of multiple modes. These locking mechanisms have the following disadvantages: the locking mechanisms between different modes cannot be switched with each other, and some locking mechanisms have complex structures, so it is necessary to upgrade the structure. Utility Model Content
[0005] The purpose of the utility model is to solve the above technical problems and provide a full-mode lifting clamp.
[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0007] A full-mode lifting clamp comprises a clamping seat shell, a clamping pull rod, a movable clamp and a fixed clamp. The lifting clamp also comprises an automatic locking hook device and a semi-automatic locking hook device. A mounting groove is provided on the top of the clamping seat shell, and a mounting surface is provided on the clamping pull rod. The mounting surface and the mounting groove form a mounting platform, and the mounting platform is used to install the automatic locking hook device or the semi-automatic locking hook device.
[0008] The automatic locking hook device comprises a secondary seat, a main seat and a lock body;
[0009] The auxiliary seat is connected to the mounting slot by screws, a slot is provided on the auxiliary seat, and a through hole is provided on the top of the slot;
[0010] The main seat is provided with a mounting hole on the top, and the mounting hole is connected to the mounting surface by screws; the main seat is provided with a mounting chamber inside, and both ends of the mounting chamber are connected to the outside world, a cover plate is provided on the top of the mounting chamber, and a limiting step is provided on the mounting chamber;
[0011] The lock body includes an automatic lock hook and a lock hook tooth seat, the automatic lock hook includes a card plate and a column, the card plate and the column are integrally formed, the card plate is arranged below the installation chamber, the column is arranged inside the installation chamber, the card plate is buckled with the card slot, the upper and lower parts of the column are respectively provided with an upper cylindrical pin and a lower cylindrical pin, and the column is sleeved with the lock hook tooth seat. The upper cylindrical pin and the lower cylindrical pin are arranged in parallel, and a plug hole can be provided on the column for plugging and fixing the upper cylindrical pin, and the column, the upper cylindrical pin and the lower cylindrical pin can also be cast by integral molding.
[0012] The lock hook tooth seat includes a lock sleeve, the lock sleeve is sleeved with the column, and the upper end surface and the lower end surface of the lock sleeve are respectively provided with an upper lock tooth and a lower lock tooth. The upper lock tooth, the lower lock tooth and the lock sleeve are integrally formed, and the two sides of the main seat can be fixed to the lock sleeve by screws, or the main seat and the lock sleeve can be integrally formed.
[0013] The number of the upper locking teeth is 4 and they are distributed along the circumference of the lock sleeve. The connection between two adjacent upper locking teeth forms an upper locking groove. The number of the lower locking teeth is 4 and they are distributed along the circumference of the lock sleeve. The connection between two adjacent lower locking teeth forms a lower locking groove. The angle formed by the two adjacent upper locking grooves and the axis of the lock sleeve is exactly 90°, and the angle formed by the two adjacent lower locking grooves and the axis of the lock sleeve is exactly 90°. The upper locking groove and the lower locking groove are staggered by 45°, so that the upper locking groove is just aligned with the lower locking groove when rotated 45°.
[0014] The principle of automatic locking of the automatic locking hook device is: when the card plate is parallel to the through hole, the card plate can pass through the through hole, so that the clamping rod can move up to clamp the material. In the clamped state, under the gravity of the automatic locking hook, the upper cylindrical pin is hung on the upper locking groove. When the material is transferred to the destination, the lifting clamp needs to be moved out of the material. The specific operation is to lower the clamping rod so that the clamping rod moves down, the card plate first contacts the bottom of the slot, and then the lower cylindrical pin slides and rotates along the lower locking tooth to the lower locking slot, so that the card plate rotates 45°. At this time, the clamp The tightening rod moves down completely, and then the clamping rod is lifted. The upper cylindrical pin slides and rotates along the upper locking tooth to the upper locking groove, so that the clamping plate rotates another 45°, making the clamping plate perpendicular to the through hole. The clamping plate and the clamping groove contact each other to form a limit, and the clamping rod cannot leave the clamping seat shell. At this time, the lifting clamp is in the open state, and the lifting clamp leaves the material to complete the lifting. Therefore, through the automatic locking hook device, each time the clamping rod moves down and resets, the clamping plate can rotate 45°, and when the clamping rod moves up, the clamping plate can rotate 45° again, so that the clamp can repeat the automatic opening and closing action.
[0015] The semi-automatic hook lock device includes a semi-automatic base, a torsion spring, a semi-automatic hook lock and a hook lock seat.

The hook lock seat is fixed to the mounting surface by screws, and the hook lock seat is engaged with the semi-automatic hook lock. Manually pressing the semi-automatic hook lock causes the semi-automatic hook lock to disengage from the hook lock seat. At this time, the clamping rod can be moved up normally to clamp the material. When the lifting clamp needs to be transferred from the material, the clamping rod is completely moved down and reset, so that the hook lock seat is engaged with the semi-automatic hook lock. The opening and closing state of the semi-automatic hook lock device requires manual operation. Compared with the automatic hook lock device, it has lower cost and simpler structure, providing customers with more choices.
[0016] Both sides of the clamping seat shell are provided with a movable guide assembly, and the movable guide assembly includes a support shaft and a movable guide sleeve, the support shaft is fixedly connected to the clamping seat shell, and the support shaft is sleeved with the movable guide sleeve. When the clamping position of the lifting clamp needs to be adjusted, the position of the lifting clamp needs to be moved, and the movable guide sleeve is provided to facilitate the rapid transfer of the lifting clamp.
[0017] In the utility model, a fixed clamping plate and a clamping seat shell are fixedly installed by a clamping shaft; two sides of the top of the movable clamping plate are sleeved with the clamping shaft, and a slope is provided on one side of the movable clamping plate close to the clamping seat shell; a slope is provided on one side of the clamping seat shell close to the clamping seat shell, and rollers are provided on both sides of the bottom of the clamping rod.
