Description
Technical field
This utility model relates to tail ring stand field, particularly relates to a kind of mobile tail ring stand.
Background technology
Tail ring stand or the last-of-chain ring of the hoist crane being currently known all are integrally fixed at hoisting chain tail end, simply play
One prevents the function that hoisting chain drops out during declining, cannot freely regulate hoisting-chain tail end adjustable height,
It is inconvenient for during use.
So being now badly in need of a kind of tail ring stand that can freely regulate hoisting chain tail end adjustable height.
Utility model content
The purpose of this utility model is to provide a kind of mobile tail ring stand, solves existing tail ring stand or last-of-chain ring can not regulate chain
The problem of bar tail end height.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
This utility model one moves tail ring stand, including the connecting portion being sequentially connected with, penetration portions and fastener；Described connection
Portion is hinged with the tail ring of hoisting chain；Described penetration portions includes two orthogonal strip the first through holes and strip second
Through hole, described first through hole and described second through hole are arranged in " ten " font, two orthogonal chain links that tolerable is adjacent
Pass through；Described fastener includes that strip third through-hole, described third through-hole and described first through hole are arranged in " one " font, and
Center side wall is got through.
Further, described connecting portion, penetration portions and fastener are formed in one structure.
Further, the length of described first through hole, the second through hole and third through-hole all with the chain link of hoisting chain
Longitudinal section width matches.
Further, the angle between described penetration portions and described fastener is not less than 90 °, and no more than 180 °.
Further, the angle between described penetration portions and described fastener is more than 90 °, and less than 180 °.
Further, the angle between described penetration portions and described fastener is 110 °.
Further, described connecting portion includes two ring ears opposed, and bearing pin is through described ring ear and hoisting chain
Tail ring, it is achieved connecting portion is hinged with hoisting chain tail ring.
Compared with prior art, Advantageous Effects of the present utility model is as follows:
This utility model is hinged to chain tail end by connecting portion, can prevent hoisting chain from dropping out during declining；Even
The portion that connects connects penetration portions and fastener, and penetration portions is provided with the first through hole in " ten " word arrangement and the second through hole, permissible
The orthogonal chain link of adjacent two is made to pass through, it is achieved regulation height；Chain can be moved to third through-hole by the first through hole
In, stop vertical chain link to pass through, it is achieved locking is fixing；Easy to use, efficiency is high, and structural strength is big, and service life is long.

Detailed description of the invention
As Figure 1-4, a kind of mobile tail ring stand, including the connecting portion 1 being sequentially connected with, penetration portions 2 and fastener 3；Institute
State connecting portion 1 hinged with the tail ring of hoisting chain；Described penetration portions 2 includes two orthogonal strip the first through hole 4 Hes
Strip the second through hole 5, described first through hole 4 arranges in " ten " font with described second through hole 5, two phases that tolerable is adjacent
The most vertical chain link passes through；Described fastener 3 includes strip third through-hole 6, described third through-hole 6 and described first through hole 4
Arrange in " one " font, and center side wall is got through, when hoisting chain is after the first through hole moves to third through-hole, adjacent two
Orthogonal chain link can only be achieved that the locking of hoisting chain by one, made this move tail ring stand and do not moving.
Specifically, described connecting portion 1, penetration portions 2 and fastener 3 are formed in one structure, it is ensured that mechanical strength, prolongation makes
Use the life-span.
In specific implementation process, the length of described first through hole the 4, second through hole 5 and third through-hole 6 all with hoisting chain
The longitudinal section width of chain link matches, to ensure that chain link can pass through the first through hole, the second through hole and third through-hole.It is disclosed
Specific embodiment, the end of the first through hole, the second through hole and third through-hole is curved, matches with the profile of chain link.
As shown in Figure 1,5, described connecting portion 1 includes two ring ears 7 opposed, and bearing pin passes described ring ear 7 and hoisting-chain
The tail ring of bar, it is achieved connecting portion 1 is hinged with hoisting chain tail ring, stable connection, structural strength is big, is moved easily tail ring stand
Rotate freely.
As in figure 2 it is shown, one of them specific embodiment, the angle between described penetration portions 2 and described fastener 3 is
110 °, the most easily distinguish penetration portions and two parts of fastener, and seamlessly transit, for locking under normal suspension status
State (with reference to Fig. 5), for intervening state (with reference to Fig. 6) after being lifted up.
Embodiment described above is only to be described optimal way of the present utility model, not to of the present utility model
Scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are new to this practicality
Various deformation that the technical scheme of type is made and improvement, all should fall into the protection domain that this utility model claims determine
In.
