Abstract
The utility model relates to a hoisting mechanism used for upright column hoisting comprising two groups of fixed pulleys, four groups of movable pulleys, hoisting cross beam and steel wire ropes. The utility model is characterized in that a hook of the hoisting machine is respectively connected with the centers of the two groups of fixed pulleys through the first steel wire rope, and two ends of the first steel wire rope are connected with the hoisting cross beam; the second steel wire rope is respectively coiled on the two groups of fixed pulleys, and the two ends of the second steel wire rope are respectively connected with the centers of the movable pulleys; the third steel wire rope is respectively coiled on the four groups of the movable pulleys, and two ends of the third steel wire rope are respectively connected with the connection points on the upright column. The utility model has three advantages: firstly, the mechanism has the simple structure, reliable and convenient use; secondly, the column can automatic turn to the upright state after being hoisted; thirdly, the mechanism has fast construction speed and less safety risks.
Description
Technical field
The utility model relates to a kind of lifting device, particularly a kind of derricking gear of being convenient to the column lifting.
Background technology
At present for the lifting of the large-scale column six suspension centre integral lifting that adopt more, only four main suspension centres are set at the column single face, lift by crane by main crane, two secondary suspension centres are sling column by secondary crane is auxiliary, after lifting by crane certain position, the rope of secondary suspension centre is removed, and column is aloft by manually it being overturn.Its weak point is: the one, and the column framework can't be in plumbness fully, is unfavorable for the in place installation of column framework in basic rim of a cup; The 2nd, for steel structure member, the column rod member is easy to generate distortion; The 3rd, both time-consuming when manually reversing, dangerous again.If the employing segmental hoisting, speed of application is slow, needs the workmen to carry out construction and installation in the junction of high-altitude member, and security risk is big.
Summary of the invention
The purpose of this utility model is exactly the weak point in the background technology, provides a kind of in hoisting process, the derricking gear of being convenient to the column lifting that can be overturn automatically by lifting components.
In order to achieve the above object, the utility model adopts following technical scheme: the derricking gear of being convenient to the column lifting, described derricking gear comprises two groups of fixed pulleys, four groups of movable pulleys, slinging beam and steel rope, the hook of lifting machine is connected with the center of two groups of fixed pulleys respectively by first steel rope, and be connected with slinging beam between the two ends of first steel rope, the winding of second steel rope difference is on two groups of fixed pulleys, the two ends of second steel rope are connected with the movable pulley center respectively, respectively winding is on four groups of movable pulleys for the 3rd steel rope, and each the 3rd steel rope two ends is connected with point of connection on the column respectively.
For a kind of optimization of the present utility model, the length of described slinging beam is greater than the width of column.
For a kind of optimization of the present utility model, described column is provided with two lifting cross sections up and down, is provided with four points of connection in each lifting cross section.
The utility model is compared with background technology, and it is simple in structure, reliable, easy to use having one; The 2nd, column turn to plumbness automatically after lifting; 30 speed of applications are fast, and security risk is little.
Description of drawings
Fig. 1 is one of a running condition scheme drawing of being convenient to the derricking gear of column lifting.
Fig. 2 be convenient to column lifting derricking gear the running condition scheme drawing two.
The specific embodiment
Embodiment 1: with reference to Fig. 1 and 2.Be convenient to the derricking gear of column lifting, described derricking gear comprises two groups of fixed pulleys 5, four groups of movable pulleys 6, slinging beam 2 and steel ropes, the hook 1 of lifting machine 4 is connected with the center of two groups of fixed pulleys 5 respectively by the first steel rope 3a, and be connected with slinging beam 2 between the two ends of the first steel rope 3a, the winding of second steel rope 3b difference is on two groups of fixed pulleys 5, the two ends of the second steel rope 3b are connected with movable pulley 6 centers respectively, respectively winding is on four groups of movable pulleys 6 for the 3rd steel rope 3c, and each the 3rd steel rope 3c two ends is connected with point of connection on the column 7 respectively.The length of described slinging beam 2 is greater than the width of column 7.
What need understand is: though the foregoing description has been done more detailed explanation to the utility model; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
Claims (2)
1. be convenient to the derricking gear that column lifts for one kind, it is characterized in that: described derricking gear comprises two groups of fixed pulleys, four groups of movable pulleys, slinging beam and steel ropes, the hook of lifting machine is connected with the center of two groups of fixed pulleys respectively by first steel rope, and be connected with slinging beam between the two ends of first steel rope, the winding of second steel rope difference is on two groups of fixed pulleys, the two ends of second steel rope are connected with the movable pulley center respectively, respectively winding is on four groups of movable pulleys for the 3rd steel rope, and each the 3rd steel rope two ends is connected with point of connection on the column respectively.
2. the derricking gear of being convenient to the column lifting according to claim 1, it is characterized in that: the length of described slinging beam is greater than the width of column.
