Description

Technical Field

[0001] The utility model belongs to the technical field of spools, in particular to a spool lifting fixture. Background Art

[0002] After the production of steel wires is completed, spools are generally used for wire winding. When the spool is full of steel wires, due to the high weight of the spool, it is rather laborious to carry it manually. At this time, a lifting tool is used for transportation, which is time-saving and labor-saving.

[0003] However, conventional lifting tools all grip the flange edge of the spool. When the steel wire is wound around the spool, the reserved space of the flange edge is small, which is not conducive to the grasping of the lifting tool. At this time, the spool is likely to fall off, causing potential safety hazards. In addition, the flange edge of the spool is relatively thin, and it is easily damaged after long-term lifting, affecting the service life of the spool. Therefore, how to safely and stably lift the spool has become a problem to be solved. Content of the Utility Model

[0004] In view of the above technical problems, the utility model provides a spool lifting fixture to solve the problem of how to safely and stably lift the spool.

The connecting plate is arranged between the suspension bracket and the claw seat, and is fixedly connected to the suspension bracket and the claw seat. The two claws are symmetrically arranged in the claw seat rotatably. The two compression springs are both installed in the upper part of the claw seat, and respectively abut against the mutually remote sides of the tops of the two claws. The lower parts of the two claws respectively extend to the lower part of the claw seat. The cross-sectional shape and size of the lower part of the claw seat are smaller than the cross-sectional shape and size of the inner hole of the spool to be lifted. The push rod is slidably inserted through the connecting plate and the upper part of the claw seat and abuts against the mutually close sides of the tops of the two claws. The push rod seat is fixed above the connecting plate. The handle is hinged to the push rod seat. One end of the connecting rod is hinged to the handle, and the other end of the connecting rod is hinged to the top of the push rod, for driving the push rod to slide up and down in the claw seat, and driving the mutually close sides of the tops of the two claws to move up and down, so that the lower parts of the two claws rotate inwards and retract into the claw seat or rotate outwards and extend out of the claw seat.

[0021] Please refer to Figure 1, Figure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , an I - shaped reel lifting fixture 100 includes: a suspension bracket 1, a connecting plate 2, a claw seat 3, a push rod seat 4, a push rod 5, a connecting rod 6, a handle 7, two claws 8 and two compression springs 9.

[0022] The connecting plate 2 is arranged between the suspension bracket 1 and the claw seat 3, and the connecting plate 2 is fixedly connected to the suspension bracket 1 and the claw seat 3.

[0023] The two claws 8 are symmetrically arranged rotatably within the claw seat 3. The two compression springs 9 are both installed inside the upper part of the claw seat 3, and respectively abut against the mutually - remote sides of the tops of the two claws 8. The lower parts of the two claws 8 respectively extend to the lower part of the claw seat 3. The cross - sectional shape and size of the lower part of the claw seat 3 are smaller than the cross - sectional shape and size of the inner hole of the I - shaped reel 101 to be lifted. This facilitates the lower part of the claw seat 3 to extend into the inner hole of the I - shaped reel for loading and unloading the I - shaped reel.

[0024] The push rod 5 is slidably inserted vertically through the connecting plate 2 and the upper part of the claw seat 3 and then abuts against the mutually - close sides of the tops of the two claws 8.

[0025] The push rod seat 4 is fixed above the connecting plate 2. The handle 7 is hinged to the push rod seat 4. One end of the connecting rod 6 is hinged to the handle 7, and the other end of the connecting rod 6 is hinged to the top of the push rod 5, for driving the push rod 5 to slide vertically within the claw seat 3 and driving the mutually - close sides of the tops of the two claws 8 to move vertically, so that the lower parts of the two claws 8 can rotate inwards and retract into the lower part of the claw seat 3 or rotate outwards and extend out of the lower part of the claw seat 3. In this way, the lower parts of the two claws 8 can rotate inwards and retract to the lower part of the claw seat 3, or can also rotate outwards and extend out of the lower part of the claw seat 3 for clamping.

[0026] Optionally, the I - shaped reel lifting fixture 100 further includes a lifting ring 11, and the lifting ring 11 is arranged at the top of the suspension bracket 1. Such a setting facilitates the lifting of the lifting fixture.

[0027] Optionally, each claw 8 includes a transverse fixed end 81, a longitudinal extension end 82 and a lateral hook - out end 83. The central part of the transverse fixed end 81 is vertically connected to the top of the longitudinal extension end 82, and the inner side of the lateral hook - out end 83 is vertically connected to the bottom of the longitudinal extension end 82.

[0028] Preferably, each claw 8 is in a T - shape and is an integrally - formed part. Such a claw 8 is more firm and the lifting is more stable.

[0029] Preferably, the upper surface of the lateral hook - out end 83 is flat. This facilitates the realization of surface contact between the claw 8 and the inner hole of the I - shaped reel, thereby increasing the service life of the claw 8.

[0030] Preferably, the transverse fixed end 81 is rotatably arranged in the upper part of the hook seat 3, the longitudinal extension end 82 passes through the upper part of the hook seat 3 and enters the lower part of the hook seat 3, and the lateral hooking end 83 is completely retracted into the lower part of the hook seat 3 when the hook 8 rotates inward. This makes it easy for the hoisting part to enter the interior of the I-shaped wheel for hoisting.

[0031] Preferably, when the two transverse fixed ends 81 are rotated to form a horizontal straight line, the connecting rod 6 and the push rod 5 are in a straight line in the vertical direction. This is convenient for locking the up and down movement of the push rod 5, preventing the two hooks 8 from rotating and retracting, and ensuring the stability of the hoisting.

[0032] Optionally, the two hook claws 8 are rotatably arranged in the hook claw seat 3 through the pin shaft 80. This facilitates the hook claw 8 to be rotatably arranged in the hook claw seat 3.

[0033] Optionally, the connecting plate 2 is detachably fixedly connected to the hanger 1 and the hook seat 3. This facilitates the disassembly, assembly and maintenance of the hoisting fixture.

[0034] The use principle of the embodiment of the I-shaped wheel hoisting fixture 100 of the utility model is as follows:

[0035] During hoisting, first turn the handle 7 upwards, so that the hook claw 8 is retracted into the lower part of the hook claw seat 3 under the action of the compression spring 9. At this time, the lower part of the hook claw seat 3 is placed into the inner hole of the I-shaped wheel, and then turn the handle 7 downwards. Under the action of the connecting rod 6, the push rod 5 moves downwards, pushing against the top of the two hook claws 8 on the side close to each other and moving downwards, so that the lower part of the hook claw 8 extends outwards and hooks the pre-processed annular groove 1011 (such as Figure 4 As shown), the I-shaped wheel is hoisted and transported. After the hoisting and transportation is completed, the handle 7 is turned upward, the lower part of the hook 8 is retracted, and the I-shaped wheel hoisting fixture 100 can be separated from the I-shaped wheel 101.

[0036] The I-shaped wheel hoisting fixture of the utility model is easy to operate, safe and stable, not easy to fall off, can stably and safely load and transport the I-shaped wheel, and has little damage to the I-shaped wheel, thereby greatly extending the service life of the I-shaped wheel.
