The utility model discloses easily take place to traditional flexible hoist and hang the problem of living with the hoist and mount thing and improve, set up the gallows, gallows joint support pipe, flexible hoist such as chain sling, wire rope passes from the stay tube in, like this, has retrained flexible hoist by the stay tube, avoids hanging the hoist and mount thing at flexible hoist lax state. The utility model discloses be particularly suitable for with the hoist and mount of occasion instrument and equipment such as the underwater operation field of vision is not good, realized that flexible hoist prevents the purpose of hanging, be favorable to the safety of hoist and mount under water, smoothly go on.
Description
Technical Field
The utility model relates to a hoist, especially be used for underwater operation prevent hanging hoist.
Background
During underwater operation construction, objects such as underwater instruments and equipment which are put under water need to be hoisted in place by means of a lifting appliance. In the hoisting process, flexible chain, steel rope, sling and other slings are used, the sling is loosened after the hoisted object is in place during the hoisting process of the flexible slings, the flexible sling naturally droops without restriction, and the hoisted object is very easy to hang. Especially, when more structural members are distributed on the hoisted equipment, a hoisting event of the hoist is easy to occur, and the difficulty is caused to the underwater construction.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can prevent effectively to hang preventing of hanging for underwater operation of hoist and mount thing when flexible hoist relaxes and hang hoist.
The problem of the utility model is realized with following technical scheme:
the utility model provides a prevent hanging hoist for underwater operation, includes gallows, stay tube and flexible hoist cable, the gallows is the annular, and the stay tube sets up two at least, and the gallows is connected to the stay tube, and the radical of flexible hoist cable is the same with the figure of stay tube, and each flexible hoist cable passes in by each stay tube respectively, and rings are connected to the top of flexible hoist cable, rings under the sub-unit connection of flexible hoist cable.
Above-mentioned prevent hanging hoist for underwater operation welds a plurality of lug on the gallows, and every stay tube welds the connecting plate near the position on upper portion, and the round pin axle passes connecting plate and lug and hinges stay tube and gallows.
The anti-hanging lifting appliance for underwater operation is characterized in that the upper lifting ring is connected with the lifting hook through a pin, and the lower lifting ring is hinged with the lifting hole in the lifting object through a pin.
The anti-hanging lifting appliance for underwater operation is characterized in that four supporting tubes are arranged, and the flexible sling is a lifting chain.
The utility model discloses to the problem that traditional flexible hoist easily takes place to hang and drag with hoist and mount thing and improve, set up the gallows, gallows joint support tube, flexible hoist such as chain sling, wire rope pass from the stay tube in, like this, can retrain flexible hoist by the stay tube, avoid hanging hoist and mount thing at flexible hoist lax state. The utility model discloses be particularly suitable for with the hoist and mount of occasion instrument and equipment such as the underwater operation field of vision is not good, realized that flexible hoist prevents the purpose of hanging, be favorable to the safety of hoist and mount operation under water, smoothly go on.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
FIG. 1 is a schematic structural view of the utility model in use;
fig. 2 is a plan view of the present invention.
The reference numbers in the figures are: 1. a hook; 2. the lifting device comprises an upper lifting ring, 3, a flexible sling, 4, a supporting pipe, 5, a lifting frame, 6, a lower lifting ring, 7, a lifting object, 8, a lug, 9 and a connecting plate.
Detailed Description
Referring to fig. 1 and 2, the present invention includes a hanger 5, a support tube 4 and a flexible sling 3. The gallows is the annular, and the stay tube sets up two at least, and the figure of flexible hoist cable is the same with the figure of stay tube. In the embodiment shown, four support pipes are arranged, the four support pipes are distributed at the inner circumference of the hanging bracket, and the flexible sling in the embodiment shown is a sling chain. Each flexible sling passes through each supporting pipe, so that the supporting pipes can restrain the flexible slings when the flexible slings do not bear weight, and the flexible slings are prevented from swinging. The top of the flexible sling is connected with an upper lifting ring 2 through a pin shaft, and the upper lifting ring is connected with a lifting hook 1; the lower part of the flexible sling is connected with a lower lifting ring 6, and the lower lifting ring is hinged with a lifting hole on a lifting object 7 through a pin shaft. As can be seen from figure 1, the equipment is arranged on the upper part of the sling 7, the length dimension of the supporting tube is required to be larger than the height dimension of the equipment, and the position of the hanger on the supporting tube is also required to be higher than the height of the equipment. A plurality of lugs 8 are welded on the hanger, a connecting plate 9 is welded at the position, close to the upper part, of each supporting pipe, and a pin shaft penetrates through the connecting plate and the lugs to hinge the supporting pipes and the hanger. The hinge structure of the hanging bracket and the supporting pipe is convenient for changing the length of the hanging chain according to the hoisting requirement, and the angle of the supporting pipe relative to the hanging bracket is correspondingly changed.
Referring to fig. 1, the utility model discloses during the use, lower rings are articulated with the lewis hole of hoist and mount thing, and upper rings are articulated with the lifting hook, if need extend the lifting chain, can pull down the round pin axle of connecting upper rings and lifting chain upper portion, and a section chain that prolongs connects the lifting chain again and is connected with upper rings. After the hoist and mount thing is transferred to underwater suitable position, the sling chain lax flagging has the restraint of stay tube, reliably guarantees that the sling chain can not be dragged to equipment instrument.
