Abstract
The invention discloses a portal crane with a jib structure. A supporting base is arranged at the center of the upper surface of a main beam of the portal crane, a jib crane is fixedly arranged on the supporting base, the supporting base is connected with the main beam by virtue of a fastening member, a joist steel operating track is welded under the main beam of the portal crane, a material in a working region below the main beam is hoisted by a hoisting hook controlled by an electric hoist, a rotary platform on the jib type crane is fixed on the supporting base, a jib luffing mechanism and a lifting mechanism are fixedly arranged on the rotary platform, a material in a region outside the main beam is hoisted a hoisting arm controlled by the jib luffing mechanism and by a hoisting hook controlled by the lifting mechanism, and a balance weight keeping running balanced is fixedly arranged on the other end face of the rotary platform. According to the technical scheme, the portal crane and the jib crane are combined into a whole, so that the engineering construction plant is saved; meanwhile, the portal crane and the jib crane can simultaneously work, so that the construction efficiency is effectively improved.
Description
Technical field:
The present invention relates to narrow space in engineering construction, a kind of transfer crane with jib structure used when limiting by workyard.
Background technology:
In the engineering constructions such as current building, railway, highway, often to carry out the carrying of a large amount of material, also will carry out the assembling of equipment at the scene, can engineering construction, because workyard is narrow and small, service conditions is limited, and the main equipment quantity can stayed into workyard limits to some extent, thus constrains speed of application, moreover, multiple stage hoisting crane cooperating, a large amount of uses must increase construction budget, brings economical burden to unit in charge of construction.
Summary of the invention:
Task of the present invention proposes one not limit by place, can a kind of transfer crane with jib structure of actv. lifting construction efficiency.
Task of the present invention completes like this, a kind of transfer crane with jib structure, it is characterized in that: the center above main beam of gantry crane is provided with bearing, bearing is fixed with arm derrick crane, described bearing is connected by fastener with between girder, I-beam section orbit is welded with below described main beam of gantry crane, material handling in girder lower work region controls suspension hook by electric block to lift by crane, turn table on described arm derrick crane is fixed on bearing, turn table is fixed with luffing mechanism and lifting mechanism, the material handling of girder exterior lateral area controls arm and the lifting of lifting mechanism control suspension hook by luffing mechanism, the other end of described rotary machinery is fixed with the counterweight keeping running balance.Arm on described arm derrick crane is fixed on one end of turn table, and described lifting mechanism is the suspension hook lifting that motor reel controls steel rope connects.Steel rope on described arm derrick crane is connected with motor reel by Shears top support.
The present invention has following effect: the technical program is combined as a whole at transfer crane and arm derrick crane, saves engineering construction place, but also can work simultaneously, lifting construction efficiency effectively.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
The problem that the technical program will solve is not by the restriction of workyard, and can lifting construction efficiency, transfer crane adopts electric block as lift system, work area is the carrying implementing material under crane girder, arm derrick crane work area is the carrying implementing material outside girder, mutual when working does not disturb, simultaneously can in the spatial synchronization work of narrow space.Specific embodiment is as follows: shown in Figure 1, and hoisting crane has two structure that hoists, and arm derrick crane is made up of main suspension hook 1, main arm 2, bearing 3, Shears 4, turning motor 5, main hoist structure 6, luffing mechanism 7, counterweight 8 and turn table 9; Transfer crane is made up of door frame operating unit 10, electric block 11, I-beam section orbit 12, door frame supporting leg 13, door frame girder 14.Center above described main beam of gantry crane is provided with bearing 3, be bolted between described bearing and girder, bearing is fixed with arm derrick crane, described arm derrick crane there is turn table 9, turn table is fixed with main arm 2 and Shears 4, Shears top support has steel rope to control suspension hook by main hoisting mechanism 6 to complete hoisting of weight, turn table is driven by turning motor 5 to be rotated, furtherly, main hoisting mechanism 6 is that the main suspension hook 10 controlled below steel rope by motor reel hoists and declines, luffing mechanism 7 controls main arm 2 to carry out luffing, in order to make turn table smooth running, the other end of turn table is provided with counterweight 8.Described auxiliary hoisting mechanism is the door frame steel structure being made up of transfer crane door frame supporting leg 13 and door frame girder 14, door frame steel structure runs driving 10 by door frame and drives operation, electric block 11 runs on I-beam section orbit 12, completes hoisting of girder lower work region weight.
More than that work is obstructed to workyard narrow space, to two kinds of hoisting cranes by connect combine after can save workyard, and can the description of effective lifting construction efficiency.
