DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] Please refer to Figure 1 , Figure 4 and Figure 6-Figure 7 The utility model provides a technical solution: a lifting quick-opening protection tooling, including a gasket 1, a first side ear 2 is fixedly welded at the lower left corner of the gasket 1, a second side ear 3 is fixedly welded at the lower right corner of the gasket 1, a notch is opened in the gasket 1 between the first side ear 2 and the second side ear 3, a U-shaped groove 4 is opened inside the first side ear 2, and an anti-slip rod 5 is rotatably connected inside the U-shaped groove 4.

[0026] The outer surface of the top of the gasket 1 is fixedly welded with a side ear 6, and the gasket 1 is arranged in a trumpet-radiated pattern. When the gasket 1 is placed at the connection between the steel wire rope and the steel casting, one side of the side ear 6 is located at the outer edge of the steel casting, and an inner angle is formed between the trumpet-radiated pattern of the gasket 1 and the side ear 6, so that the steel casting is clamped.

[0027] The inner circle radius of the washer 1 is 20 mm ± 1 mm. By adopting the above technical solution, the inner part of the washer 1 of the wire rope is prevented from slipping during hoisting.

[0028] In the specific implementation process, when it is necessary to hoist the cast steel workpiece, after the steel wire rope is strung, the steel wire rope is inserted from the notches of the two gaskets 1 respectively, and then the back sides of the two gaskets 1 are padded at the connection between the steel wire rope and the cast steel quick opening, so that the cast steel quick opening is located on the back side of the gasket 1. During lifting, the gasket 1 is tightened by the self-weight of the cast steel, so that the back inner angle of the gasket 1 clamps the cast steel to prevent it from sliding, thereby protecting the steel wire rope through the gasket 1. Before the application of the tooling, six steel wire ropes are required each year. After the application of the tooling, one steel wire rope is consumed every two years after being protected by the gasket 1. In comparison, the annual consumables before application are 6*1200, which is 7,200 yuan per year, and after application, the annual consumables are 600 yuan, which can save 6,600 yuan in consumables costs each year. Not only is the hoisting process safer, but the consumables cost is also greatly reduced.

[0029] Embodiment 2:

[0030] Please refer to Figure 2-Figure 4 The utility model provides a technical solution: a receiving groove 7 is opened inside the second side ear 3, and an adjusting groove 8 is opened on the second side ear 3 above the receiving groove 7. A rotating shaft 9 is rotatably connected inside the adjusting groove 8, and a blocking rod 10 is fixedly sleeved on the outer surface of the rotating shaft 9. A side plate 12 is fixedly connected inside the adjusting groove 8, and a coil spring 11 is fixedly sleeved on the outer surface of the rotating shaft 9, and the other end of the coil spring 11 is fixedly connected to the side plate 12.

[0031] In the specific implementation process, after the wire rope is inserted into the notch of the gasket 1, the anti-slip rod 5 is rotated. When the anti-slip rod 5 contacts the baffle rod 10, the baffle rod 10 is squeezed inward, so that the baffle rod 10 drives the rotating shaft 9 to rotate, and the winding spring 11 is wound. When the anti-slip rod 5 is detached from the surface of the baffle rod 10, the force on the baffle rod 10 disappears. At this time, the baffle rod 10 is reset under the action of the winding spring 11. After the wire rope is inserted into the inside of the gasket 1, the anti-slip rod 5 is used to prevent the wire rope from detaching from the inside of the gasket 1, and the baffle rod 10 is blocked by the limiting rod 16 to limit the anti-slip rod 5, thereby increasing the stability of the wire rope between the gaskets 1.

[0032] Embodiment 3:

[0033] Please refer to Figure 2-Figure 5 The utility model provides a technical solution: an insertion rod 13 is movably inserted into the top of the second side ear 3, a pull plate 14 is fixedly connected to the top outer surface of the insertion rod 13, a limiting rod 16 is fixedly connected to the bottom outer surface of the insertion rod 13, the limiting rod 16 is fitted with the outer surface of the blocking rod 10, a spring 15 is fixedly connected to the top outer surface of the second side ear 3, the top outer surface of the spring 15 is fixedly connected to the bottom outer surface of the pull plate 14, and the spring 15 is sleeved on the outer surface of the insertion rod 13.

[0034] A slide groove is provided inside the adjustment groove 8, and the width of the slide groove is greater than the width of the limiting rod 16. The slide groove provides a channel for the movement of the limiting rod 16, and when the pull plate 14 is pulled upward, the insertion rod 13 is driven to make the limiting rod 16 slide inside the slide groove.

[0035] During the specific implementation process, when it is necessary to remove the wire rope to disassemble the gasket 1, the pull plate 14 is pulled upward, and the pull plate 14 drives the insertion rod 13 to move upward, so that the spring 15 is stretched, and the insertion rod 13 drives the limiting rod 16 to move upward, so that the limiting rod 16 is disengaged from the surface of the baffle rod 10, and the baffle rod 10 is released from the limit. When the anti-detachment rod 5 is pulled outward, the baffle rod 10 can be driven to rotate outward, so that the anti-detachment rod 5 is disengaged from the accommodating groove 7, so that the notch of the gasket 1 is conductive, and then the wire rope can be separated from the gasket 1.

[0036] Working principle: When the utility model is in use, when it is necessary to lift the cast steel workpiece, after the steel wire rope is strung, the steel wire rope is respectively inserted from the notches of the two gaskets 1, and then the back sides of the two gaskets 1 are padded at the connection between the steel wire rope and the cast steel quick opening, so that the cast steel quick opening is located on the back side of the gasket 1. During lifting, the gasket 1 is tightened by the self-weight of the cast steel, so that the back inner angle of the gasket 1 clamps the cast steel to prevent it from sliding, thereby protecting the steel wire rope through the gasket 1. Before the application of the tooling, six steel wire ropes are required each year. After the application of the tooling, one steel wire rope is consumed every two years after being protected by the gasket 1. In comparison, the annual consumables before application are 6*1200, which is 7,200 yuan per year, and after application, the annual consumables are 600 yuan, which can save 6,600 yuan in consumables costs each year. Not only is the lifting process safer, but the consumables cost is also greatly reduced.

[0037] After the steel wire rope is stuck into the notch of the gasket 1, the anti-slip rod 5 is rotated. When the anti-slip rod 5 contacts the baffle rod 10, the baffle rod 10 is squeezed inward, so that the baffle rod 10 drives the rotating shaft 9 to rotate, and the winding spring 11 is wound. When the anti-slip rod 5 is detached from the surface of the baffle rod 10, the force on the baffle rod 10 disappears. At this time, the baffle rod 10 is reset under the action of the winding spring 11. After the steel wire rope is stuck into the inside of the gasket 1, the anti-slip rod 5 is used to prevent the steel wire rope from detaching from the inside of the gasket 1, and the baffle rod 10 is blocked by the limiting rod 16 to limit the anti-slip rod 5, thereby increasing the stability of the steel wire rope between the gaskets 1.

[0038] When it is necessary to remove the wire rope to disassemble the gasket 1, pull the pull plate 14 upwards, the pull plate 14 drives the insertion rod 13 to move upwards, so that the spring 15 is stretched, and the insertion rod 13 drives the limiting rod 16 to move upwards, so that the limiting rod 16 is disengaged from the surface of the baffle rod 10, and the baffle rod 10 is released from the limit. When the anti-detachment rod 5 is pulled outward, the baffle rod 10 can be driven to rotate outward, so that the anti-detachment rod 5 is disengaged from the accommodating groove 7, so that the notch of the gasket 1 is conductive, and the wire rope can be separated from the gasket 1.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
