Abstract
The utility model discloses a lifting device for construction of a coal bunker. A fixed pulley is arranged on a carrier plate of the coal bunker; a hoisting winch is arranged near the coal bunker; a suspension point is fixed at the position, which is far away from the fixed pulley, of the carrier plate of the coal bunker; a movable pulley is arranged on a lift rope point of a cage, and a wire rope of the lifting winch rotates around the fixed pulley and the movable pulley, and then is fixedly connected with the suspension point. The rotation problem in the lifting process is removed due to the fact that the cage bears the acting force in two slant directions.
Description
Technical field
The utility model relates to bont.
Background technology
At present in the district coal bin work progress, about the personnel, material lifting is a very important link.Existing bont is at the coal bunker top board fixed pulley to be installed, and at lifting winch of the other installation of coal bunker, the steel rope of lifting winch hangs upper cage by fixed pulley.Hang because cage belongs to single rope, the effect of force of inertia can make cage rotate in lifting, has caused certain hidden danger to safety in production.
Summary of the invention
The purpose of this utility model is in order to eliminate the problem that cage easily rotates in the lifting process, prior art to be improved, designing a kind of bont that does not rotate.
For achieving the above object, the technical solution of the utility model is, a kind of bont for the coal bunker construction, it is at the coal bunker top board fixed pulley to be installed, and at lifting winch of the other installation of coal bunker, it is characterized in that, fix a hitch point at the coal bunker top board away from the position of fixed pulley, a movable pulley is set on the rope point of cage, and the steel rope of lifting winch is walked around fixed pulley and movable pulley, then is fixedly connected on the hitch point.
The utility model has the advantages that: so because cage is subjected to two application forces obliquely to eliminate the rotational problems in the lifting process.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data, 1-coal bunker top board, 2-fixed pulley, 3-lifting winch, 4-cage, 5-movable pulley, 6-hitch point.
The specific embodiment
As shown in Figure 1, bont of the present utility model, at coal bunker top board 1 fixed pulley 2 to be installed, at the other lifting winch 3 of installing of coal bunker, fix a hitch point 6 at coal bunker top board 1 away from the position of fixed pulley 2, a movable pulley 5 is set on the rope point of cage 4, and the steel rope of lifting winch 3 is walked around fixed pulley 2 and movable pulley 5, then is fixedly connected on the hitch point 6.
Claims (1)
1. one kind is used for the bont that coal bunker is constructed, it is at the coal bunker top board fixed pulley to be installed, at the other lifting winch that is equipped with of coal bunker, it is characterized in that, be fixed with hitch point at the coal bunker top board away from the position of fixed pulley, be provided with movable pulley on the rope point of cage, the steel rope of lifting winch is walked around fixed pulley and movable pulley, then is fixedly connected on the hitch point.
