Abstract

The invention relates to a special sling device used for lifting nuclear waste. The special sling device is characterized by comprising a connecting plate installed on the beam of a trolley frame, wherein the connecting plate is provided with a telescopic sleeve device; a steel wire rope system and a fixed pulley mechanism connected with the connecting plate are arranged in the telescopic sleeve device; the fixed pulley mechanism is fixed to the bottom end of the telescopic sleeve device; and the fixed pulley mechanism is provided with a special gripping apparatus connecting assembly. The special sling device has the advantages that the whole telescopic sleeve device is driven to move together with the steel wire rope when the steel wire ropes lifts up and falls down, the telescopic sleeve can integrally perform a guiding direction, so that the situation that the steel wire rope of the traditional crane swings can be avoided, accurate positioning can be guaranteed when the special sling device is used for lifting the nuclear waste without shifting and the like, and the operation safety performance of the lifting mechanism of the crane is improved.

Description

The special hanger device that is used for the handling nuke rubbish
Technical field
The invention belongs to hoisting crane manufacturing technology field, particularly relate to a kind of special hanger device that is used for the handling nuke rubbish.
Background technology
Hoisting crane is widely used in fields such as Aeronautics and Astronautics, nuclear power, and lifting mechanism has very important application as the main portion of hoisting crane in hoisting crane.Tradition lifting mechanism suspender is the structure that adopts the direct handling article of steel rope connecting shackle, when lifting altitude surpasses more than 3 meters or 3 meters, the situation that institute's handling weight waves along with steel rope can occur.Because the particularity of many working spaces and nuke rubbish radiation and harmfulness are very big; If adopt traditional suspension hook directly to come the handling nuke rubbish; Therefore; From the purpose of safety guard-safeguard, unforeseen circumstances appears waving etc. in the nuke rubbish article that must forbid institute's handling, so traditional lifting mechanism suspender is the specific (special) requirements that can't satisfy the handling nuke rubbish.
Summary of the invention
The present invention for solve the technical matters that exists in the known technology provide a kind of simple in structure, accuracy of positioning is high, handling is steady, prevent that article from waving and can guarantee the special hanger device that is used for the handling nuke rubbish of crane hoisting mechanism safe operation.
The technical scheme that the present invention takes for the technical matters that exists in the solution known technology is:
The special hanger device that is used for the handling nuke rubbish; It is characterized in that: comprise the connecting panel that is installed on the trolley frame crossbeam; The telescopic shaft device is housed on the said connecting panel; Be provided with in the said telescopic shaft device and the connecting panel bonded assembly wire rope rope fixed pulley mechanism that unifies, said fixed pulley mechanism and telescopic shaft device bottom are fixed, and special-purpose gripping apparatus coupling assembling is housed in fixed pulley mechanism.
The present invention can also adopt following technical scheme:
Said telescopic shaft device is to be made up of through the nested structure socket the more piece sleeve.
Said sleeve is to be made up of welding side's tube.
All be shaped on guide runner that is used to slide up and down and the locating piece that is used for fixing on said every joint sleeve.
Advantage and good effect that the present invention has are: because the present invention adopts technique scheme; The telescopic shaft device that play the guiding role promptly is housed on the trolley frame cross-beam connecting plate; Steel rope drives whole telescopic shaft device and moves with steel rope when hoisting and descend, and telescopic shaft integral body can play the effect of guiding; The situation that so not only can avoid the conventional hoist steel rope to wave; Can accurately locate when the handling nuke rubbish but also can guarantee it, situation such as skew can not occur, improve the safety performance of crane hoisting mechanism operation.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the structural representation of telescopic shaft device of the present invention;
Fig. 3 is the structural representation of fixed pulley of the present invention mechanism;
Fig. 4 is the lateral plan of Fig. 3.
Among the figure: 1, connecting panel; 2, telescopic shaft device; 2-1, sleeve; 2-2, guide runner; 2-3, locating piece; 3, fixed pulley mechanism; 4, special-purpose gripping apparatus coupling assembling; 5, steel rope system.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1-Fig. 4, be used for the special hanger device of handling nuke rubbish, comprise the connecting panel 1 that is installed on the trolley frame crossbeam.Telescopic shaft device 2 is housed on the said connecting panel, and said telescopic shaft device is to be made up of through the nested structure socket more piece sleeve 2-1, and two promptly adjacent joint sleeves are nested against one another respectively, and can move along same direction successively.On said every joint sleeve 2-1, all be shaped on guide runner 2-2 that is used to slide up and down and the locating piece 2-3 that is used for fixing, in the present embodiment, all be equipped with guide runner 2-2 and locating piece 2-3 on four faces of every joint sleeve 2-X.Because the height difference that crane job is on-the-spot; But what the sleeve of this telescopic shaft device adopted is nested structure; Can regulate the telescopic shaft height of devices according to operation field; Do not influence hoisting crane single-piece volume, this nested structure can satisfy the requirement of special operation condition, can save the space again simultaneously.In the present embodiment, said telescopic shaft device is to be made up of 5 joint sleeve 2-1, and said sleeve 2-1 is processed by welding side's tube.The sleeve quantity of said telescopic shaft device is not limited to 5 joints, also can increase according to the height at crane job scene or successively decrease.Be provided with in the said telescopic shaft device and connecting panel bonded assembly steel rope system 5 and fixed pulley mechanism 3, the 5th joint sleeve bottom of said fixed pulley mechanism and telescopic shaft device 2 is fixed, and special-purpose gripping apparatus coupling assembling 4 is housed in fixed pulley mechanism 3.
When steel rope hoists or descend; The drive telescopic shaft hoists synchronously or descends, and at this moment, telescopic shaft integral body can play the effect of guiding; Make the lifting mechanism of hoisting crane when the handling nuke rubbish, can guarantee accurate location; Can avoid steel rope to wave situation like this, guarantee safety under special circumstances, and then guarantee the safety performance of crane hoisting mechanism operation.
Principle of work of the present invention is:
When the lifting mechanism hoisting heavy of hoisting crane; Gravity is delivered in the fixed pulley mechanism 3 through steel rope system 5; Because fixed pulley mechanism is fixed on the 5th joint sleeve bottom of telescopic shaft device 2; Steel rope system will drive the 5th joint sleeve and rise and descend, and drive the 4th joint sleeve, the 3rd joint sleeve and other sleeve successively and rise gradually and descend.Steel rope is a stressed member in rising and decline process, and the telescopic shaft device only plays the effect of guiding, occurs waving in the time of can preventing steel rope handling weight like this, has increased lifting mechanism single-piece stability.
