Description

Technical Field

[0001] The utility model relates to a motor rotor hoisting tool, in particular to a portable hoisting device which can keep the hoisting stable and reliable. Background Art

[0002] The rotor is assembled from a variety of heavier parts. During the rotor processing, it is often necessary to move the rotor. If it is directly moved manually, it will not only contaminate the outer surface of the rotor, but also be inconvenient to carry and easily cause safety risks of falling. At present, there are also some lifting mechanisms, which have a handle, and under the handle are L-shaped grippers that are cross-configured with each other, and the grippers have hinge points in different places. The problem with the above lifting mechanism is that since the components are connected by hinge points, the components on both sides are close to each other, which makes the lifting not very stable. Utility Model Content

[0003] The utility model aims to provide a rotor lifting fixture with an anti-loosening mechanism, and solves the technical problem of how to hoist the rotor stably.

[0004] A rotor lifting clamp with an anti-loosening mechanism comprises a connecting rod, a gripper, an anti-loosening mechanism, a plate, a grid rubber sheet, a first hinge shaft and a second hinge shaft; the connecting rod has two groups and is arranged in an articulated interval and a first hinge shaft is arranged at the end hinge position, each group of connecting rods has two connecting rods and is hinged to each other in a V shape; the gripper also has two groups and is arranged in an articulated interval and a second hinge shaft is arranged at the middle position, and the end position of the gripper is hinged to the other end position of the connecting rod; the first hinge shaft and the second hinge shaft are provided with an anti-loosening mechanism, and the anti-loosening mechanism is designed with an outer rod, an inner rod and a tightening knob; wherein one end of the outer rod is fixed on the first hinge shaft, one end of the inner rod is arranged on the second hinge shaft, and the other end is inserted into the interior of the outer rod, the tightening knob is screwed to the outer rod and squeezes the inner rod; the gripper is a J-shaped structure as a whole, and the arc position of the J-shaped structure is provided with a plate arranged up and down, and the outer surface of the plate has a grid rubber sheet.

[0005] The connecting rod and the upper half of the gripper are hinged to each other to form a diamond structure.

[0006] The pasting plate is arranged transversely between two spaced grippers.

[0007] The beneficial effects of the utility model are as follows: by configuring the first hinge shaft and the second hinge shaft, the lateral spacing distance between the two grippers is increased, thereby expanding the lateral gripping area, which makes the motor gripping more secure; at the same time, an anti-loosening mechanism is configured, and when the rotor is gripped to be lifted, the outer rod and the inner rod move outward through the pulling of the two hinge shafts, and at this time, the tightening knob is used to squeeze and tighten the inner rod, so that the relative position between the inner rod and the outer rod no longer changes, thereby avoiding the safety problem of the rotor falling caused by the possible loosening of the grippers.

[0017] Please refer to Figure 1 to Figure 2 The rotor lifting fixture with an anti-loosening mechanism in the figure is designed with two sets of connecting rods 1, two sets of grippers 3, an anti-loosening mechanism 2, two sets of plates 4, two sets of grid rubber sheets 6, a first hinge shaft 51, and a second hinge shaft 52; compared with the existing components, this case adds the design of the first hinge shaft 51, the second hinge shaft 52, and the anti-loosening mechanism 2, so that the rotor can be lifted more stably.

[0018] The connecting rod 1 in the figure is a sheet-like structure, which has two groups spaced apart from each other, each group has two connecting rods and are hinged at one end position by a first hinge shaft 51, and the length of the first hinge shaft 51 is the length of the interval between the two groups of connecting rods 1; the above-mentioned first hinge shaft 51 can be provided with a handle, so that the entire lifting clamp can be lifted by the handle, and the two connecting rods 1 of each group of connecting rods 1 are hinged to each other into a V-shaped structure, and are hinged to cooperate with the end position of the gripper 3 at the other end position, so that the upper half of the connecting rod 1 and the gripper 3 are hinged to each other into a diamond structure, so that its shape can be changed according to the lifting situation.

[0019] The grippers 3 in the figure also have two groups spaced apart from each other, each group having two grippers that are hinged in the middle through a second hinge shaft 52, and each gripper 3 is a J-shaped structure as a whole. The length of the second hinge shaft 52 is the length of the interval between the two groups of grippers 3; an anti-loosening mechanism 2 is arranged between the second hinge shaft 52 and the first hinge shaft 51, and the anti-loosening mechanism 2 is designed with an outer rod 21, an inner rod 22, and a tightening knob 23; wherein one end of the outer rod 21 is fixed on the first hinge shaft 51, one end of the inner rod 22 is fixed on the second hinge shaft 52, and the other end of the inner rod 22 is inserted into the other end of the outer rod 21 and the inner rod 22 and the outer rod 21 are fixed to each other by tightening the knob 23.

[0020] The plate 4 in the figure is a long strip structure, which is arranged above and below the arc portion of the J-shaped structure of the gripper 3 and is installed horizontally between two spaced grippers 3. The plate 4 can be directly welded to the gripper 3.

[0021] The mesh rubber sheet 6 in the figure is attached to the attachment plate 4 and faces the rotor. The mesh rubber sheet 6 has a certain thickness to ensure sufficient gripping friction force.
