Description

The Current Collector Sleave start-stop system

Technical field

The utility model relates to a kind of Current Collector Sleave start-stop system, is specially the start-stop system who is used in the quadrangle steel structure Current Collector Sleave.

Background technology

Be accompanied by high speed development of national economy, the lifting lifting job is used more and more frequently and general in the every field of economic construction.Current Collector Sleave commonly used in the lifting lifting job comprises: suspender, be the rigidity load-engaging device, as: suspension hook, grab bucket, clamp, sucker, special hanger etc.; Rigging is for binding the flexible instrument of workpiece, as steel rope, loop chain, syntheticfibres suspender belt etc.; And end fitting, as suspension ring, shackle, wire clips etc.

During for the bigger article of lifting weight, use steel rope and quadrangle steel structure Current Collector Sleave usually, but in use there is very big potential safety hazard in existing quadrangle steel structure Current Collector Sleave.

For example, existing product the time directly utilizes guide rod to open anchor clamps in lifting, and that utilizes self gravitation and guide rod in hoisting process fixedly steps up article, and guide rod is easy to the phenomenon that occurs blocking when sliding.And, need use two anchor clamps when sometimes lifting big article, there is very big accident potential in the as easy as rolling off a log nonsynchronous phenomenon of anchor clamps that occurs in the use;

And for example, can also dispose at quadrangle steel structure Current Collector Sleave and a kind ofly to be used for controlling the mechanism that anchor clamps open and close specially, but its complex structure needs the keying that guide finger has come anchor clamps of self, move dumb, the use inconvenience.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of Current Collector Sleave start-stop system, its anchor clamps that overcome existing quadrangle steel structure Current Collector Sleave use guide rod control anchor clamps keying existence can not be opened rapidly, two anchor clamps use nonsynchronous defective simultaneously, and special mechanism control anchor clamps open and close that the anchor clamps that exist are opened rapidly, complicated in mechanical structure, the defective damaged easily, and custom-designed simple in structure, open and close rapid, easy to use, safe performance height, can be convenient for people to novel Current Collector Sleave start-stop system that existing installation transformation or new product are used.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

A kind of Current Collector Sleave start-stop system, it comprises a sleeve, this upper cartridge is provided with that the block teeth bottom is provided with block teeth on one, this sleeve inner is provided with a rotation core, one switch block is fixed on this rotation core, and between block teeth and this time block teeth, the bottom of this rotation core is provided with a tapered end to this switch block on this, and this tapered end is corresponding with the snap close that is arranged on the anchor clamps top.

In technique scheme, block teeth and this time block teeth are cyclic structure on this, offer the triangle teeth on it, and the tooth form angle of these teeth is 95 °, and all the other interior angles are 47 ° and 38 °, and should go up the tooth pitch setting of staggering of block teeth and this time block teeth.

This switch block also is a cyclic structure, and it has and should go up block teeth and this time block teeth ingear triangle teeth; This upper cartridge is welded with a flange, and this rotation core top is provided with a little axle, and it is by the intermediate throughholes of this flange; This switch block and this rotation core are fixed by pin; This sleeve is provided with and is press-fitted lubricating cup.

The utility model utilizes the interlock of switch block and block teeth tooth up and down to realize rotation core half-twist angle, reach the locked of control tapered end and snap close and relieving, and then the quadrangle of adjusting quadrangle steel structure Current Collector Sleave, the opening and closing of anchor clamps have also promptly been realized, it has advantages such as simple in structure, that safety performance is high, keying is rapid, both can transform existing installation, more help the popularization of new product.

The specific embodiment

As Fig. 1-shown in Figure 7, the utility model comprises the sleeve 2 with flange 1 welding, sleeve 2 tops are provided with block teeth 4, the bottom is provided with down block teeth 3, and sleeve 2 inside are provided with rotation core 8, and switch block 7 is fixedly welded on the rotation core 8 by pin 6, switch block 7 is arranged between block teeth 4 and the following block teeth 3, the bottom of rotation core 8 is provided with tapered end 9, and tapered end 9 is combined with special snap close 10, and snap close 10 is located on the anchor clamps.Last block teeth 4 and following block teeth 3 be cyclic structure, and offer the triangle teeth on it: the tooth form angle of these teeth is 95 °, and all the other interior angles are 47 ° and 38 °, and block teeth and this time block teeth tooth pitch setting of staggering on this.Rotation core 8 tops more carefully are a little axle, and it can be by the intermediate throughholes of flange 1.

Working process of the present utility model is as follows:

At first flange 1 is fixed on the crossbeam of Current Collector Sleave top, snap close 10 is fixed on the crossbeam of Current Collector Sleave bottom, the Current Collector Sleave start-stop system is vertical with horizontal surface, when anchor clamps do not press from both sides weight, anchor clamps are in open configuration, tapered end 9 rotates the teeth and the interlock mutually of following block teeth 3 of switch block 7 bottoms on the core 8 this moment in snap close 10 and locked with snap close 10;

When Current Collector Sleave put down the folder article, tapered end 9 can push up the bottom of snap close 10, and the switch block 7 on the rotation core 8 just can slide until the teeth and the interlock mutually of last block teeth 4 on switch block 7 tops along the tooth on the last block teeth 4, and at this moment tapered end 9 just can half-twist.

When Current Collector Sleave promotes article, rotation core 8 will be to downslide under the effect of self gravitation and article gravity, the teeth on switch block 7 tops of rotation on the core 8 just can with last block teeth 4 break away from until with following block teeth 3 interlocks, because the particularity of angle design, this moment, thereby tapered end 9 will break away from snap close 10 by half-twist, after tapered end 9 spins off from snap close 10, the parallelogram sturcutre of anchor clamps will elongate, anchor clamps will dwindle, thereby clamp article, can under the effect of article self gravitation, article be stepped up with rear jig.

When article were transferred, tapered end 9 also can touch the bottom of snap close 10, thereby tapered end 9 is again can half-twist stuck with snap close 10, keeps opening of anchor clamps.

The utility model is provided with on sleeve 2 and is press-fitted lubricating cup 5, is convenient for people to the lubricating oil of annotating, and makes 8 actions of rotation core more flexible; This start-stop system's closed design has simultaneously more effectively kept the in-to-in cleaning; Switch block 7 is fixed and is welded on the rotation core 8 by pin 6, more effective maintenance switch block 7 and the stability and the mechanical strength that rotate core 8; Sleeve 2 adopts solid drawn pipe, and briquetting, switch block all adopt quenching technical, have guaranteed the single-piece mechanical strength.

The utility model utilizes the switch block 7 and the interlock realization of upper and lower block teeth to rotate core 8 half-twist angles, reach control tapered end 9 and the locked of snap close 10 and relieving, and then the opening and closing of anchor clamps have been realized, it has advantages such as simple in structure, that safety performance is high, keying is rapid, both can transform existing installation, more help the popularization of new product.
