Description
Technical field
The utility model relates to a kind of weight-lifting equipment annex, is specifically related to a kind of automatic coupling and decoupling sling device.
Background technology
General lift beam, the form of arm-tie hanging hook has two kinds, one is that another kind is by electrically realizing automation by manpower.Manpower divide again two kinds, one realizes by physical push-and-pull completely, and another is a set of little mechanism of design, can alleviate the labour intensity of operator; The problem that solves for now by manpower is not subject to popular welcome, and employing electrically realizes automation cost can be increased a lot.
Utility model content
The technical matters that will solve of the present utility model is to provide a kind of automatic coupling and decoupling sling device, neither needs artificial, does not also need electrical control.
In order to solve above technical matters, the utility model by the following technical solutions:
A kind of automatic coupling and decoupling sling device, comprising:
Two groups of arm-tie framves, two groups of arm-tie framves are separately positioned on and lift inside beam two web, and often group comprises two spaced arm-ties, are integrated between the upper and lower two ends of arm-tie that two groups of arm-tie framves are relative by arm-tie pinned connection;
Two groups of rocking bar framves, often organize rocking bar frame and have two spaced rocking bars, rocking bar is fixedly connected with arm-tie, and often in group rocking bar frame two rocking bars be crisscross arranged, connected as one by rocking bar bearing pin between the rocking bar upper end that two groups of rocking bar framves are relative;
Two limiting stopper groups, every limiting stopper group comprises two limiting stoppers, limiting stopper be fixed on arm-tie lower outside and with lift beam and be fixedly connected with.
In above-mentioned automatic coupling and decoupling sling device preferred version, in two groups of arm-tie framves, between two arm-tie upper end two bearing pins, clearance is greater than chevron suspension hook external dimensional envelope.
In above-mentioned automatic coupling and decoupling sling device preferred version, in two groups of arm-tie framves, between two arm-tie lower end two bearing pins, clearance is less than the hook distance of chevron suspension hook.
In above-mentioned automatic coupling and decoupling sling device preferred version, rocking bar two ends are semicircular structure, and the diameter of lower end semicircular structure is greater than upper end semicircular structure diameter.
The utility model beneficial effect: neither need artificial, also do not need electrical control; Structure is simple, practical, solves chevron hook automatic hitch and unhook problem; Shorten the preparation before and after crane job and end time, improve production efficiency; Not only alleviate the manual labor of people but also reduce cost of labor.

Detailed description of the invention
Better understand the utility model for the ease of those skilled in the art, be described in further details below in conjunction with the drawings and specific embodiments to the utility model, following is only exemplary do not limit protection domain of the present utility model.
With reference to accompanying drawing 1, Fig. 2 and Fig. 3, a kind of automatic coupling and decoupling sling device, comprise two groups of arm-tie framves, two groups of rocking bar framves and two limiting stopper groups, two groups of arm-tie framves are separately positioned on and lift inside beam 1 liang of web, often group comprises between two spaced arm-ties, 5, the two groups of arm-tie that arm-tie frame is relative about 5 two ends by connecting as one with upper pin 6 and lower bearing pin 7 respectively; Often organize rocking bar frame and have two spaced rocking bars 3, rocking bar 3 is fixedly connected with arm-tie 5, and often in group rocking bar frame two rocking bars 3 be crisscross arranged, connected as one by rocking bar bearing pin 8 between rocking bar 3 upper end that two groups of rocking bar framves are relative; Every limiting stopper group comprises two limiting stoppers 2, limiting stopper 2 be fixed on arm-tie 5 lower outside and with lift beam 1 and be fixedly connected with.
In the present embodiment, in two groups of arm-tie framves, between two arm-tie 5 upper end two bearing pins, clearance is greater than chevron suspension hook 4 external dimensional envelope; In two groups of arm-tie framves, between two arm-tie 5 lower end two bearing pins, clearance is less than the hook distance of chevron suspension hook 4.
In the present embodiment, rocking bar 3 two ends are semicircular structure, and the diameter of lower end semicircular structure is greater than upper end semicircular structure diameter.
Utility model works process is as follows: with reference to accompanying drawing 4, under arm-tie 5 is in free state, on the limiting stopper 2 that arm-tie 5 leans on, can not fall down, the position of limiting stopper 2 will according to the size of chevron suspension hook 4, when making the spacing of two ends arm-tie 5 upper end two pin shaft hole be A, chevron suspension hook 4 can fall from top smoothly; With reference to accompanying drawing 5, when chevron suspension hook 4 fall always touch rocking bar bearing pin 8 time, utilize the pressure that the deadweight of chevron suspension hook 4 produces rocking bar 3, arm-tie 5 and upper pin 6 thereof toward side-sway in chevron suspension hook 4, in the process of pendulum, chevron suspension hook 4 can not produce with upper pin 6 or arm-tie 5 and interfere, until the center-of-gravity position of arm-tie 5 crosses lower bearing pin 7, thus make the upper pin 6 of arm-tie 5 lean against chevron suspension hook 4 staight shank position as shown in Figure 6, at this moment chevron suspension hook 4 stops declining; With reference to figure 7, chevron suspension hook 4 starts to rise, and along with chevron suspension hook 4 rises, the width between centers of the upper pin 6 of arm-tie 5 starts to increase, slowly with the hook of chevron suspension hook 4 apart from equal, so just achieve automatic hitch.The total centre of gravity of system remains on beyond size C, and arm-tie 5 and upper pin 6 just start to topple over toward both sides under the effect of conducting oneself with dignity, and when bottom fallen by chevron suspension hook 4, upper pin 6 is deviate from completely, and arm-tie 5 gets back to initial position, realizes automatically-unhooked.
Above only describes groundwork of the present utility model and preferred implementation, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection domain of the present utility model.
