Description

Technical Field

[0001] The utility model relates to the technical field of a cable-pulled suspended storage platform, in particular to a height adjustment device for a suspension ring of a suspended storage platform. Background Art

[0002] In order to make use of the indoor high space, hanging storage platforms suspended on the roof or house beams by cables such as steel wire ropes are gradually being promoted and applied.

[0003] Generally, the lower ends of multiple steel wire ropes are fixed to the four corners of the storage platform, such as the steel wire ropes are directly locked to the respective steel lifting rings through transition steel rings or directly locked to the respective steel lifting rings, and the lifting rings are then fixed to the respective corners of the horizontal beam or longitudinal beam of the storage platform. In actual use, due to fatigue and relaxation of cables such as steel wire ropes, after a period of use, the height of the entire storage platform or the height of one of the four corners needs to be adjusted in time.

[0004] The prior art hanging storage platform lifting ring height adjustment device still has the following shortcomings: the upper end of the adjusting bolt, which is generally made of steel, is fixed to the lifting ring, and the lower end of the adjusting bolt extends a long distance from the bottom surface of the horizontal beam or longitudinal beam of the storage platform. In actual use, people are sometimes touched or even scratched, and clothes are also scratched. In addition, since the upper end of the bolt is fixed to the lifting ring such as welding, generally only the beam fixing nut of the fixed beam is used, so the firmness, stability and reliability of the above structure after fixing are still insufficient. This structure also has a shortcoming. If a cross pin is set at the bottom end of the bolt to prevent the bolt and the nut from falling off from each other, the above-mentioned phenomenon of injuring people or scratching objects will be more serious. Therefore, generally no cross pin is set, which poses a certain safety hazard. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a height adjustment device for a suspension type storage platform lifting ring which can prevent the protruding end of the adjusting bolt from injuring people or scratching objects and has relatively good firmness and reliability after being fixed.

[0006] The technical solution of the utility model is to provide a height adjustment device for a hanging ring of a suspended storage platform, comprising a hanging ring and a bolt; a threaded hole is provided on the bottom ring of the hanging ring, the bolt passes through the bolt through hole on the beam of the suspended storage platform from bottom to top, the big head of the bolt at the bottom end of the bolt is axially limited on the bottom surface of the beam, the top surface of the beam is provided with a beam fixing nut screwed on the bolt, and the bolt is also screwed with a hanging ring fixing nut.

[0007] After adopting the above structure, the utility model of the hanging type storage platform lifting ring height adjustment device has the following advantages:

[0008] When the height of the device needs to be adjusted, first loosen the eye fixing nut and the beam fixing nut, then adjust the bolt upward or downward to the required height, and then tighten the two fixing nuts.

[0009] Since there is a threaded hole on the bottom ring of the lifting ring, the bolts are screwed and fixed from bottom to top. After tightening, the free ends of the bolts extending out of the threaded holes are both inside the two side rings of the lifting ring, preventing or even avoiding the disadvantage of the prior art that the bolts extend very long downward and easily scratch people or scratch clothes, thereby ensuring the friendliness of the free ends of the bolts in contact with people or objects.

[0010] Because there is a beam fixing nut screwed onto the bolt on the top surface of the beam, and a lifting ring fixing nut is also screwed onto the bolt, the structure is relatively simple and the height adjustment process is relatively convenient. The two fastening nuts also have their own division of labor and double fastening, which greatly improves the firmness, stability and reliability after height adjustment and fixation.

[0011] Furthermore, a transverse pin through hole is provided at the top of the bolt, and a transverse pin is accommodated in the transverse pin through hole to prevent the bolt and nut from falling off from each other. With the above structure, the phenomenon of the bolt and nut falling off caused by vibration during the use of the suspended storage platform such as loading and unloading goods can be prevented, thereby eliminating possible safety hazards.

[0012] Furthermore, the cross pin is a cotter pin, one end of which is a spherical big head, and the other end of the half pin that extends out of the cross pin through hole is bent into an arc, and the other half pin is shorter than the half pin and has an arc-shaped end. The above makes two improvements to the cotter pin of the prior art, one is that the big head is spherical, and the other is that the ends of the two halves of the pin are both arc-shaped. After adopting the above structure, the friendliness of the cotter pin in contact with people or objects is guaranteed, and the harmonious unity of preventing the bolts and nuts from falling off and preventing the cross pin from injuring people or scratching objects is achieved.

[0013] Furthermore, the lifting ring is waist-shaped with a height greater than a width. With the above structure, the height adjustment dimension of the bolt is greatly increased, which not only meets the actual height adjustment needs, such as the height adjustment within a range of 300mm, but also ensures that the bolt is arranged from bottom to top to prevent or even avoid the downward protruding part of the bolt from injuring people or scraping objects.

[0014] Furthermore, there is an opening on the bottom ring of the lifting ring, and a small-top-large-bottom-large frustum nut is fixed at the opening, and the threaded hole on the bottom ring of the lifting ring is the threaded hole of the frustum nut, and the bottom diameter of the frustum nut is larger than the diagonal size of the hexagon of the lifting ring fixing nut. After adopting the above structure, the contact area between the lifting ring fixing nut and the lifting ring bottom ring, i.e., the bottom surface of the frustum nut, is increased, and the firmness, stability and reliability of the re-fixation of the device after height adjustment are further guaranteed.

[0015] Furthermore, the beam is a rectangular steel tube, and the bolt holes are arranged on the top plate and the bottom plate of the rectangular steel tube. After adopting the above structure, the contact area between the bolt head at the bottom of the bolt and the bottom surface of the beam, and the contact area between the beam fixing nut and the top surface of the beam are both larger, which further ensures the firmness, stability and reliability of the re-fixation of the device after height adjustment.

[0016] Furthermore, the big head of the bolt is hemispherical with a bottom plane, and the bottom plane has a groove for the force-applying tool to apply force. With the above structure, it is convenient to tighten or loosen the bolt to ensure fixation or adjust the height, and further ensure the friendliness of the bottom end of the bolt to contact with people or objects.
