Description

Increase high pedestal jib crane

Technical field

This utility model relates to a kind of hoisting crane, and particularly a kind of high pedestal jib crane of increasing belongs to hoisting crane manufacturing technology field.

Background technology

Weight-lifting equipment is used in a large number Dam and is built and the equipment erecting stage, because the former design lifting of this weight-lifting equipment is highly limited, can not satisfy the differing heights that install the camp site, the user just need to buy weight-lifting equipment again for solving practical problems, thereby increases construction budget and affect the duration.

Summary of the invention

Goal of the invention: the purpose of this utility model provides a kind of high pedestal jib crane of increasing that can satisfy different sling heights requirements.

Technical scheme: a kind of high pedestal jib crane of increasing, comprise the traveling gear, door frame, the section of increasing, rotary disk, operator's compartment, swing type mechanism, luffing mechanism, lifting mechanism, perpendicular tower and the crane arm that are installed on the ground rail, described traveling gear is installed in the door frame bottom, the described section of increasing is installed on the door frame, the described section of increasing top is provided with rotary disk, and rotary disk is connected by swing type mechanism with operator's compartment; The described section of increasing comprises lower pillar stand, central post, upper pillar stand and main chord, and described lower pillar stand, central post and upper pillar stand are respectively square truss structure, are bolted.

For the intensity that improves the section of increasing reduces its weight simultaneously, described main chord is the I-beam section structure.

In order to adapt to the needs of various working, the height of the described section of increasing can be regulated height as requested.

Beneficial effect: the utility model can adapt to the needs of various working and regulate the highest sling height, and can exchange with similar erecting equipment, for convenience detach, transportation, installs, and improves the on-the-spot range of use of user.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that the section of increasing of the present utility model is installed in the structural representation on the door frame;

Fig. 3 is that lower pillar stand of the present utility model is installed in the structural representation on the door frame.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, a kind of high pedestal jib crane of increasing, comprise the traveling gear 1, door frame 2, the section of increasing 3, rotary disk 4, operator's compartment 5, swing type mechanism 6, luffing mechanism 7, lifting mechanism 8, perpendicular tower 9 and the crane arm 10 that are installed on the ground rail, described traveling gear 1 is installed in door frame 2 bottoms, the described section of increasing 3 is installed on the door frame 2, the described section of increasing 3 tops are provided with rotary disk 4, and rotary disk (4) is connected by swing type mechanism 6 with operator's compartment 5; The described section of increasing 3 comprises lower pillar stand 31, central post 32, upper pillar stand 33 and main chord 34, and described main chord 34 is the I-beam section structure.The height of the described section of increasing 3 can be regulated height as requested.

As shown in Figure 2, the described section of increasing 3 comprises lower pillar stand 31, central post 32, upper pillar stand 33 and main chord 34, and described lower pillar stand 31, central post 32 and upper pillar stand 33 are respectively square truss structure, are bolted.

As shown in Figure 3, described lower pillar stand 31 is connected with plane four leg angle upper junction plates on the door frame 2.

After door frame is increased, when also needing to keep hanging 30t, make 30 tons of steel ropes into 5 multiplying powers by 6 multiplying powers.This scheme easy disassembly and transportation reach simultaneously hoisting crane and can hang down frame and overhead exchange according to user's operating needs, and namely a hoisting crane can be by two uses.
