Description

Technical Field

[0001] This utility model relates to the field of lifting and hoisting technology, and in particular to a combined adjustable lifting clamp. Background Technology

[0002] An electric chain hoist, also known as a chain electric hoist, is a small and lightweight lifting device. It consists of an electric motor, a transmission mechanism, and a sprocket.

[0003] The existing technology, CN202411019521.1, describes a tooling structure for lifting materials in a confined space. However, the lifting tooling used in conjunction with this structure cannot be adjusted. If the product has a special structure and its weight is not in the center, it will tilt during lifting, causing the center to shift. Furthermore, some mechanisms may not be able to clamp or hold the product.

[0004] Therefore, a modular adjustable lifting clamp needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a combined adjustable lifting clamp to overcome the above-mentioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A combined adjustable lifting clamp includes a guide rail, characterized in that it further includes a lifting rod disposed on the guide rail, a lifting rod clamping block for fixing to the guide rail and for mounting the lifting rod, a lifting ring fitted onto the lifting rod by a fixing ring, clamping claws respectively disposed on both sides of the guide rail, and an adjustment module for driving the clamping claws to adjust their positions. The fixing ring is sleeved on the lifting rod and can move along the lifting rod. The lifting rod clamping block holds a locking piece for fixing and limiting the lifting rod. A portion of the lifting rod clamping block is fitted onto the guide rail. The lifting rod clamping block also has a through hole for mounting the lifting rod. The lifting rod clamping block can move along the guide rail.

[0008] Preferably, the guide rail is a circular guide rail, and two sets are arranged in parallel vertically.

[0009] Preferably, a number of guide rail fixing blocks are fitted on the guide rail, the guide rail fixing blocks fit the guide rail and are fixed and locked by screws and bolts, guide rail fixing blocks are respectively provided on both sides of the clamping claw, which also serve as a limit to restrict the movement of the clamping claw, and guide rail fixing blocks are also provided on both sides of the lifting rod clamping block.

[0010] Preferably, a locking slot is provided on the boom.

[0011] Preferably, the adjustment module includes a guide shaft disposed on the guide rail, a guide sleeve mounted on the clamping claw and sleeved outside the guide shaft, a lead screw threaded to the clamping claws on both sides, and a drive device for driving the lead screw to rotate.

[0012] Preferably, the gripping claw has a slot for engaging with the product gripper.

[0013] The beneficial effects of this utility model are: the clamping claws of this technical solution can be adapted to the actual shape of the item, and can grip internally or externally; at the same time, the position of the center of the lifting ring can be adjusted according to the needs, so as to ensure the balance during lifting and improve safety.

[0019] Reference Figures 1 to 4 A combined adjustable lifting clamp includes a guide rail 1, a lifting rod 4 disposed on the guide rail, a lifting rod clamping block 5 for fixing with the guide rail and for mounting with the lifting rod, a lifting ring 10 mounted on the lifting rod by a fixing ring 9, clamping claws 2 disposed on both sides of the guide rail, and an adjustment module for driving the clamping claws 2 to adjust their positions.

[0020] The guide rail is a circular guide rail, and two sets are arranged in parallel at the top and bottom. The two sets facilitate adjustment and ensure strength. When adjusting the position, the two sets of guide rails work together to ensure high stability and strength.

[0021] To fix the guide rail and prevent it from shaking, several sets of guide rail fixing blocks 3 are fitted onto the guide rail. The guide rail fixing blocks fit the guide rail and are fixed and locked in place by screws and bolts. Guide rail fixing blocks 3 are respectively provided on both sides of the clamping claw 2, which also limit the movement of the clamping claw 2. Guide rail fixing blocks 3 are also provided on both sides of the lifting rod clamping block to limit the lifting rod clamping block and fix the guide rail.

[0022] The fixing ring 9 is sleeved on the lifting rod and can move along the lifting rod 4, thereby driving the lifting ring 10 installed on the fixing ring 9 to move and adjust the center position of the lifting. The fixing ring 9 is fixedly connected to the lifting rod by a fixing nut. When it is moved to the lifting position that needs to be adjusted, tightening the fixing nut will fix the fixing ring, and loosening it will allow it to move along the lifting rod for adjustment.

[0023] The rod clamping block 5 holds a locking piece 8 for fixing and limiting the rod. Part of the rod clamping block 5 is fitted with the guide rail. The rod clamping block 5 also has a slot for the rod to pass through. The rod clamping block 5 can move along the guide rail to adjust its position and is fixed by bolts and nuts.

[0024] To further secure the guide rod, a locking slot is provided on the rod for the locking plate to be inserted. The locking plate 8 is placed between the rod clamping blocks 5 and is partially embedded in the rod's latch to achieve fixation.

[0025] The adjustment module includes a guide shaft mounted on the guide rail, a guide sleeve mounted on the clamping claws 2 and sleeved outside the guide shaft, a lead screw 7 threadedly connected to the clamping claws 2 on both sides, and a handwheel 6 for driving the lead screw to rotate. The handwheel can also be replaced with other driving devices such as a servo motor, as long as it can drive the lead screw to rotate. By driving the lead screw to rotate, the clamping claws 2 at both ends are moved. And through the guide shaft and the guide sleeve, they move along the guide shaft, driving the clamping claws 2 at both ends to move closer or further away, thereby realizing the clamping or releasing of the clamping claws 2.

[0026] The clamping claw 2 has a slot for cooperating with the product clamping claw. The product part is placed in the slot to achieve internal clamping or external gripping. Similarly, the clamping claw 2 can also achieve the above functions.

[0027] In this embodiment, the drive screw rotates, thereby moving the clamping claws 2 at both ends. Guided by the guide shaft and guide sleeve, the claws move along the guide shaft, causing them to move closer or further away, thus clamping or releasing them. This allows for horizontal and vertical position adjustment to maintain balance during lifting. When adjustment is needed, the nut is loosened, and the claw moves along the lifting rod 4, causing the lifting ring 10 installed on the fixed ring 9 to move, thus adjusting the lifting center position. Similarly, the lifting rod clamp 5 loosens its bolts and nuts and moves along the guide rail to adjust the position of the lifting rod.

[0028] The advantages of this utility model are that the clamping claws can be adapted to the actual shape of the item, and can grip internally or externally; at the same time, the position of the center of the lifting ring can be adjusted according to the needs, so as to ensure the balance during lifting and improve safety.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
