Abstract
The utility model relates to a construction elevator, comprising a lifting frame, a lifting cage, a hoist, three steel wires and a plurality of pulleys. The pulley is fixed on the top of the lifting frame; one end of the steel wire is connected with the lifting cage after going round a pulley, and the other end of each steel wire is winded on the roller of the hoist after going around another pulley. The utility model is characterized in that the roller of the hoist is divided into three sub-rollers, and one end of each wire is connected with the lifting cage, and the other end is winded on one of the three sub-rollers separately. Comparing with the prior art, the utility model has the advantages of high safety and no slipping of the steel wires.
Description
Technical field:
The utility model relates to a kind of elevator, particularly a kind of construction elevator.
Background technology:
Existing building hoist comes branch to mainly contain single rope building hoist and four rope building hoists by promoting with the quantity of rope.The propulsion source of single rope building hoist mainly is a winch.Single rope building hoist is owing to only be to use single wire rope, in case wire cable rupture, cage will fall, and therefore, degree of safety is low, and use has been under an embargo.The propulsion source of four rope building hoists is a towing machine, its principle of work is to drive the cage rising, descend by traction sheave on the towing machine and the friction force between steel rope, this kind building hoist falls cage because of counterweight is unbalance easily automatically, even counterweight is not unbalance, also can skid between steel rope and traction sheave, this situation can be quickened the damage of steel rope, and particularly when starting, skidding is more serious.
Summary of the invention:
It is a kind of safe that goal of the invention of the present utility model is to provide, and the safety misadventure that cage falls can not take place because of the fracture of a certain steel rope, and the steel rope building hoist that can not skid.
The utility model is to realize like this, comprise raising legs, cage, winch, steel rope, pulley, pulley is fixed on the top of raising legs, steel rope one end is walked around pulley and is connected with cage, one end is walked around on the cylinder that pulley is wound on winch, and its special feature is that the cylinder on the winch is the sub-cylinder that three joints are separated, and steel rope is three, three steel rope one ends are connected with cage, and the other end is wound on respectively on the mutual sub-cylinder of separating of three joints.During use, winch drives cylinder and rotates, and makes cylinder do the action of folding and unfolding steel rope, and the drive cage is done to rise accordingly, descending motion, so that load, transport the construction article.
The utility model compared with the prior art, owing to adopted three knot cylinders to drive the motion of three steel ropes respectively independently, even wherein one or two wire cable ruptures wherein can not cause the appearance of the safety misadventure that cage falls yet at once, improved the safety performance of building hoist, simultaneously, winch drives the steel rope motion, does not just have the appearance of phenomenons such as skidding, guaranteed the service life of steel rope, therefore, the utlity model has safe, the advantage that steel rope can not skid.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of winch cylinder.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises raising legs 1, cage 2, winch 3, steel rope 4, rope regulator 18, pulley 5a, 5b, pulley 5a, 5b is fixed on the top of raising legs 1, steel rope 4 one ends are walked around pulley 5a and are connected with cage 2 by rope regulator 18, one end is walked around on the cylinder 6 that pulley 5b is wound on winch 3, its special feature is that the cylinder 6 on the winch 3 is the sub-cylinder 7 that three joints are separated, 8,9, each sub-cylinder 7,8,9 by dividing plate 10,11 separate, steel rope 4 is three, pulley 5a, 5b is three rope pulley groups, three steel rope 4 one ends are connected with cage 2, and the other end is wound on the cylinder 7 that three joints are separated mutually respectively, 8, on 9.
Here, in order securely three steel ropes to be securely fixed on the cylinder 7,8,9 separately, wherein side at cylinder 6 is provided with a steel rope briquetting 12, opposite side is provided with two steel rope briquettings 13,14, dividing plate 15,16 backs of steel wire penetrating drum 6 both sides on the sub-cylinder 7,9 are fixed on the dividing plate 15,16 by steel rope briquetting 12,13, and the steel rope on the sub-cylinder 8 successively passes dividing plate 10,15 backs and is fixed on the dividing plate 15 by briquetting 14.
In order to improve the safety performance of operation, prevent that cage 2 from use falling because of lifting rope 19 wear and rupture, be provided with insurance hawser 20 at rope regulator 18 and 2 of cages.Like this, even lifting rope 19 wear and rupture, insurance hawser 20 also can be held cage 2, prevents that cage 2 from falling.
Claims (4)
1, a kind of building hoist, comprise raising legs, cage, winch, steel rope, pulley, pulley is fixed on the top of raising legs, steel rope one end is walked around pulley and is connected with cage, one end is walked around on the cylinder that pulley is wound on winch, it is characterized in that the cylinder on the winch is the sub-cylinder that three joints are separated, and steel rope is three, three steel rope one ends are connected with cage, and the other end is wound on respectively on the mutual sub-cylinder of separating of three joints.
2, building hoist according to claim 1 is characterized in that being separated by dividing plate between each sub-cylinder.
