Description

Technical Field

[0001] The invention belongs to the technical field of mold lifting, and in particular relates to a lifting rope anti-falling device. Background Art

[0002] During the use of molds, it is often necessary to transport the molds. For the transportation of molds, a crane, a lifting rope and a lifting lug are usually used for lifting. Because the molds are generally large in size and have a certain weight, and some molds even weigh more than several tons, when transporting the molds, if the attached Figure 3 As shown in the figure, the lifting rope is directly hung on the lifting ring. When the mold is touched, the crane is frequently operated up and down, and the lifting rope may be separated from the lifting ring, causing the mold to fall and resulting in a safety accident. Summary of the Invention

[0003] The present invention aims to provide a device for preventing a lifting rope from falling off, so as to solve the problem that the existing lifting rope may fall off from the lifting ring and cause the mold to fall.

[0004] A lifting rope anti-fall device in this scheme includes a retaining ring and a shift rod, the shift rod includes a first shift rod and a second shift rod of the same axis, a gap is provided between the first shift rod and the second shift rod, the length of the gap is greater than the diameter of the lifting ring, the two ends of the retaining ring are respectively connected to the mutually close ends of the first shift rod and the second shift rod, an accommodating space is formed inside the retaining ring, and the lifting ring enters the accommodating space through the gap, a blind hole is provided on the first shift rod along its axis, and a through hole is provided on the second shift rod along its axis, a sliding shift rod is slidably connected to the through hole, the sliding shift rod can slide into the blind hole, and a locking member for fixing the sliding shift rod is provided on the second shift rod.

[0005] The working principle and beneficial effects of this solution are as follows: since the sliding lever slides in the through hole on the second sliding lever and can slide into the blind hole on the first lever, when lifting the mold, after the lifting rope is put on the lifting ring, the lifting ring is placed into the accommodating space from the gap, and then the sliding lever is slid through the center hole of the lifting ring and moved into the blind hole, and then the sliding lever is locked by the locking piece, so that the anti-slip device of this solution is installed on the lifting ring, and the first lever and the second lever are limited to prevent the lifting rope from falling off the lifting ring, thereby preventing the mold from falling.

[0006] Furthermore, the retaining ring is provided with a first threaded hole, to which a first screw is connected. With this arrangement, the first screw can be rotated to press against the lifting ring, thereby securing the lifting ring in the accommodation space, thereby securing the lifting rope anti-slip device of the present invention to the lifting ring and preventing it from shaking.

[0007] Furthermore, a rotation handle is provided at one end of the first screw away from the retaining ring, and the rotation handle is a second screw, which is perpendicular to the first screw. This arrangement facilitates the rotation of the first screw, and the first and second screws are waste screws, which are welded together to improve the utilization rate of waste materials.

[0008] Furthermore, the locking member includes a second threaded hole provided on the second lever, and a first locking screw connected to the second threaded hole, and the first locking screw is rotated to abut against the sliding lever. This arrangement facilitates the locking of the sliding lever.

[0009] Furthermore, a slider is provided within the first lever, and a spring is connected between the slider and the bottom of the blind hole. When the sliding lever moves into the blind hole, it pushes the slider and compresses the spring. With this arrangement, when removing the sliding lever, the first locking screw is rotated to no longer resist the sliding lever, and the spring force pushes the sliding lever outward, thereby facilitating the sliding lever to exit the blind hole and the gap, making it easier to remove the rope anti-slip device from the lifting ring.

[0010] Furthermore, an observation port is provided on the first gear lever. Through such a configuration, the length of the sliding gear lever extending into the blind hole can be checked through the observation port, which facilitates adjustment of the spring compression amount and avoids the situation where the restoring force of the spring is too large or too small after compression.

[0011] Furthermore, the locking member further includes a third threaded hole provided on the first lever, and a second locking screw connected to the third threaded hole, wherein the second locking screw is rotated to press against the sliding lever. This arrangement further increases the locking force on the sliding lever. BRIEF DESCRIPTION OF THE DRAWINGS
