Abstract
The utility model relates to the field of a crane, in particular to an improved structure of a single-beam hoist-type crane. The improved structure of the single-beam hoist-type crane is composed of a driver installing chamber, a cab, a platform, an upper support leg, lower support legs, a ladder and a lower beam, wherein the lower end of the platform is connected with the ladder; the upper end of the platform is fixed with the cab; the upper end of the cab is connected with the driver installing chamber; the driver installing chamber is connected with the upper support leg; and the lower ends of the lower support legs are fixed with the lower beam. The two lower support legs form a man-shaped structure. The improved structure of the single-beam hoist-type crane has the advantages that the carrying capability of the specific man-shaped structure of the lower support leg is better than that of the common single-beam crane; a space needs to be reserved on the two sides when the main beam of the common single-beam crane is welded with the upper support leg so as to ensure the security performance; moreover, with the adoption of the man-shaped structure, the materials are saved, the bearing effect is more excellent after welding. In addition, the vision of the cab is broadened so as to see the whole site when things are hanged, so that the accident ratio is reduced.
Description
Technical field
The utility model relates to the hoisting crane field, concretely, relates to a kind of improvement structure of single-beam cucurbit hoisting crane.
Background technology
Usually hoisting crane is by lifting mechanism, operating unit, luffing mechanism and swing type mechanism, adds metallic magnetism, engine installation, manipulation control and necessary auxiliary device and combines.
Single kingpost cantalever transfer crane is a kind of of transfer crane, and is simple in structure because of it, makes easy for installationly, and sole mass is little, and girder mostly is inclined to one side rail box frame structure.Compare with two girder transfer cranes, it is weak that integral rigidity is wanted.Single main door beam crane door leg has the manufacturing of L type and two kinds of form .L of C type type easy for installation, stressing conditions is good, sole mass is less, but, lift cargo is made or crooked shape by the leg of the smaller relatively .C type in space at supporting leg place, purpose is bigger horizontal space, so that goods passes through leg smoothly.
Summary of the invention
The purpose of this utility model provides a kind of improvement structure of single-beam cucurbit hoisting crane of easy to operate, safe and reliable, applied range.
The utility model is made of driver's installation room, driver's cab, platform, upper supporting leg, following supporting leg, ladder, cross sill; The platform lower end connects ladder, and the upper end is driver's cab fixedly, and the driver's cab upper end connects driver's installation room, and driver's installation room links to each other with upper supporting leg, and following supporting leg lower end has cross sill to fix.
Described supporting leg down is two, and forms " people " font structure.
Before the work, driver's cab rests in upper supporting leg becomes horizontality with platform position, and the driver enters driver's cab by ladder, controls hoisting crane.Then, the walking of dolly drives driver's cab and moves, make driver's cab with monkey below crane girder and platform along the rail parallel motion.After work was finished, the driver was by stop line, and driver's cab is rested in position before the work, and the driver walks out from ladder, leaves the operating room.
Advantage of the present utility model is: " people " font structure of following supporting leg uniqueness, and stressed better than common single-beam crane aspect stressed; Need guarantee safety performance in the both sides spacing when common single-beam crane girder and upper supporting leg welding, " people " font structure has been saved material, and welding back load-bearing effect is better; And make the broad view of driver's cab, can see entire field when hanging thing, reduced accident rate.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Reference numeral shown in Figure 1 is as follows: driver's installation room 1, driver's cab 2, platform 3, ladder 4, following supporting leg 6, upper supporting leg 7, cross sill 8.
The utility model is made of driver's installation room 1, driver's cab 2, platform 3, upper supporting leg 7, following supporting leg 6, ladder 4, cross sill 8; Platform 3 lower ends connect ladder 4, and the upper end is driver's cab 2 fixedly, and driver's cab 2 upper ends connect driver's installation room 1, and driver's installation room 1 links to each other with upper supporting leg 7, and following supporting leg 6 lower ends have cross sill 8 fixing.
Described supporting leg 6 down is two, and forms " people " font structure.
Principle of work of the present utility model is: before the work, driver's cab 2 rests in the position of 3 one-tenth horizontalitys of upper supporting leg 7 and platform, and the driver enters driver's cab 2 by ladder 4, controls hoisting crane.Then, the walking of dolly drives driver's cab 2 and moves, make driver's cab 2 with monkey below crane girder and platform 3 along the rail parallel motion.After work was finished, the driver was by stop line, and driver's cab is rested in position before the work, and the driver walks out from ladder 4, leaves the operating room.
" people " font structure of following supporting leg 6 uniquenesses, stressed better than common single-beam crane aspect stressed; Need guarantee safety performance in the both sides spacing when common single-beam crane girder and upper supporting leg welding, " people " font structure has been saved material, and welding back load-bearing effect is better; And make the broad view of driver's cab 2, can see entire field when hanging thing, reduced accident rate.
Claims (2)
